-# Peridot
+# Obsolete
-Peridot is a framework for composed, intelligent and distributed user
-experiences.
-
-Applications not explicitly designed to interoperate (and possibly implemented
-in different programming languages) are ephemerally downloaded and dynamically
-composed to run in a shared context. The framework manages application
-lifecycle, resources and view hierarchy; and well as context and suggestion
-infrastructure.
-
-State of Peridot experiences is transparently synchronized across user devices
-using a distributed offline-first storage system.

-# Firestore-based cloud provider
-
-This directory contains a Firestore-based implementation of the [cloud provider]
-interface.
-
-[TOC]
-
-## Testing
-
-The tests are packaged with Ledger tests.
-
-In order to run the unit tests:
-
-```sh
-fx run-test -t cloud_provider_firestore_unittests ledger_tests
-```
-
-In order to run the [validation tests], follow the [cloud sync set-up
-instructions] to set up a Firestore instance, configure the build environment
-and obtain the sync parameters.
-
-Then, run the validation tests as follows:
-
-```sh
-fx run-test -t validation_firestore ledger_tests
-```
-
-Note that `validation_firestore` is only a launcher for the actual tests,
-`cloud_provider_validation_tests`. As a result, you will need to look at `fx
-log` output to see if the tests passed.
-

-# Configuration
-
-This document describes the configuration required for a Firestore Database
-project to be used with `cloud_provider_firestore`.
-
-*** note
-These instructions are relevant only when setting up one's own server instance,
-and not needed to use an existing server instance.
-***
-
-## Rules
-
-In the [Firebase Console], under `Database > Cloud Firestore > Rules`, set the
-rules to:
-
-```
-service cloud.firestore {
- match /databases/{database}/documents {
- match /users/{uid}/{everything=**} {
- allow read, write: if request.auth.uid == uid;
- }
- }
-}
-```
-
-[Firebase Console]: https://console.firebase.google.com/
-
-## Credentials
-
-In order to run tests (end-to-end sync tests, sync benchmarks, validation tests)
-against a Firestore instance, you need the following:
-
- - **API key** - available in `Project Settings / General`
- - **credentials file** for a service account - available in `Project Settings /
- Service accounts`. Click on "Generate new private key".
-
-See [cloud sync set-up instructions] for instructions on how to use this
-information to run these tests.

-# Coroutine library
-
-## Description
-This coroutine library can help you write highly asynchronous code, and avoid
-"callback hell". It does so by allowing a function (or method) to be paused and
-resumed by swapping [execution contexts](context/context.h). It makes the code
-*look* synchronous, while remaining asynchronous under the hood, with all the
-usual concurrency pitfalls, such as race conditions and deadlocks.
-
-Coroutines are different than multithreading, but both can be used together.
-See [CoroutineHandler](coroutine.h) for details.
-
-## Usage
-
-Here are some tips on good use of the Coroutine library.
-
-### Use CoroutineManager in classes
-
-Usually, coroutines created within a class object should not survive its
-destruction, whether because continuing the processing didn't make sense, or
-because resources captured by the coroutine would be destroyed (such as `this`).
-
-[CoroutineManager](coroutine_manager.h) is a proxy class for
-[CoroutineService](coroutine.h). `CoroutineManager` interrupts the coroutine it
-created when destroyed, and can be created using the `CoroutineService` vended
-by an `Environment` object.
-
-You should consider using `CoroutineManager` if you use coroutines in your
-class.
-
-Free-standing functions probably don't need `CoroutineManager` and can use
-`CoroutineService` directly.
-
-### When receiving INTERRUPTED, return
-
-`coroutine::ContinuationStatus::INTERRUPTED` means another part of your code
-requested the coroutine to terminate gracefully. This would be the case if the
-`CoroutineManager` or `CoroutineService` who created this coroutine are
-destroyed.
-
-This mechanism is needed because other parts of the program don’t know the heap
-allocations made inside the coroutine, as well as other cleanup performed by
-the destructors of objects created or owned by the coroutine. When a coroutine
-destruction is needed, it is resumed with an `ContinuationStatus::INTERRUPTED`
-and it is the coroutine's job to unwind its call stack.
-
-Usually, the only thing you need to do when receiving a
-`ContinuationStatus::INTERRUPTED` is to return immediately. Doing more work is
-dangerous as some objects you rely on may be destroyed already.
-
-
-### Don’t use Yield and Resume
-
-You probably don’t need to use `Yield()` and `Resume()` directly.
-[SyncCall](coroutine.h) is a utility function that can be used to wrap any
-asynchronous call, so that you don't have to use `CoroutineHandler` methods
-directly.
-
-If you have an asynchronous function with the signature
-`AsynchronousCall(Argument, std::function<void(Status, Result)>)`, then you can
-wrap it such as:
-``` cpp
-Argument argument(...)
-Status status;
-Result value;
-if (coroutine::SyncCall(handler,
- [argument](fit::function<void(Status, Result)> cb) {
- AsynchronousCall(argument, std::move(cb));
- }, &status, &value) == coroutine::ContinuationStatus::INTERRUPTED) {
- return Status::INTERRUPTED;
-}
-if (status != Status::OK)
- return status;
-Process(value);
-```
-
-`SyncCall` will ensure the asynchronous call is made and the coroutine paused,
-and then resumed when the asynchronous callback is executed.
-
-
-### Use coroutine::Wait with for loops
-
-Coroutines make it very easy to write asynchronous code, but the execution of
-the coroutine itself remains sequential. In particular, `for` loops are not run
-in parallel. If you can, avoid the following pattern:
-``` cpp
-std::vector<Result> results;
-for (auto& obj : objects_) {
- Result result;
- // Don't do that! SynchronousFrobinate does not need to wait for the previous
- // call to finish.
- if (SynchronousFrobinate(handler, obj, &result) ==
- coroutine::ContinuationStatus::INTERRUPTED) {
- return;
- }
- results.push_back(std::move(result));
-}
-```
-
-Instead, make the asynchronous calls directly and use
-[coroutine::Waiter](coroutine_waiter.h) to collate the results:
-``` cpp
-auto waiter = fxl::MakeRefCounted<
- callback::Waiter<Status, std::unique_ptr<Result>>>(Status::OK);
-
-for (auto& obj : objects_) {
- AsyncFrobinate(obj, waiter->NewCallback());
-}
-
-Status status; std::vector<std::unique_ptr<Result>> result;
-if (coroutine::Wait(handler, std::move(waiter), &s, &result) ==
- coroutine::ContinuationStatus::INTERRUPTED) {
- return Status::INTERRUPTED;
-}
-```

-## Generated ErrorNotifierDelegate ##
-
-The ledger API is sending a status and closing the connection on unexpected
-errors for every interface that extends ledger.ErrorNotifier. These interfaces
-must also implement a |Sync| method that will return when all requests called
-before the |Sync| call have been handled.
-
-When impementing such an interface, one must keep track of each connection to be
-able to close it with the correct status in case of error, and must also
-implement the |Sync| method.
-
-To reduce the amount of repeating code, the files in this directory allow to
-automatically generate an ErrorNotifierDelegate and an implementation of the
-base interface that delegates to it.
-
-When one wants to implement an interface extending ledger.ErrorNotifier, one
-therefore only need to implement the generated delegate interface. For each
-method in the initial interface, the delegate will have a corresponding method
-with an additional callback taking a ::fuchsia::ledger::Status. The implementor
-must call this additional callback when the call is finished, with either
-Status::OK if the call is successful, or with any error status if it is not.
-
-When one wants to bind a request, one can instantiate a new
-ErrorNotifierBinding, associating it with an implementation of the Delegate. The
-binding will take care of forwarding the call to the Delegate, as well as handling
-the error reporting and the |Sync| calls.
-
-For an example, see error\_notifier\_proxy\_base\_unittest.cc, which implements
-the ErrorNotifierTestDelegate interface that is automatically generated from the
-ErrorNotifierTest FIDL interface defined in fidl/error\_notifier\_test.fidl.

-# Peer-to-peer communication
-
-The Ledger supports peer-to-peer synchronization between devices able to communicate directly.
-
-# Protocol
-The protocol used for P2P communication is based on message passing. Messages
-are defined in //peridot/bin/ledger/p2p_sync/impl/message.fbs. This is not an
-RPC-like system : most messages do not expect any response, and the protocol
-should be resilient to devices not answering.

-// (base-to-left and base-to-right).
-// - At the initialization time, it advances each internal IP to their first
-// diff. Each IP (as viewed from here) is on one key: the key of the latest
-// diff it returned.
-// - We always advance the IP with the lowest key, or the one not finished yet.
-// If both are on the same key, we advance both.
-// - The current key considered by the ThreeWayIterator is the lowest key of the
-// latest left and right diffs. If one IP is finished, then the current key is
-// the key of the other IP's diff.
-// - When sending the ThreeWayIterator diff, we consider the current key (per
-// above). If both IPs are on the same key, the diff is easy (we just send
-// everything). However, if the IPs are on different keys, or one of them is
-// finished, we have to consider multiple cases:
-// - If the base entry is present, it means the key/value was present in the
-// base revision. Given that the other IP moved past this key, there is no
-// diff on that side and we copy the base entry to that side entry within
-// the tree-way diff change.
-// - If the base entry is not present, it means the key/value was not present
-// in the base revision and it is an addition.

-# benchmark
-
-## Overview
-This directory contains Ledger [trace-based benchmarks]. Each benchmark is
-implemented as a client connected to Ledger and using its API to perform one or
-more of its basic operations (creating a page, writing/deleting entries, ...).
-
-## Run benchmarks
-
-### Using trace spec files
-The easiest way to run a benchmark is using the associated trace spec file,
-for example:
-
-```
-trace record --spec-file=/pkgfs/packages/ledger_benchmarks/0/data/put.tspec
-```
-
-You can read more on the trace spec file format in the [trace-based benchmarking
-guide](https://fuchsia.googlesource.com/docs/+/master/development/benchmarking/trace_based_benchmarking.md#specification-file).
-
-### Tracing benchmark apps directly
-You can also trace the app directly:
-
-```
-trace record --categories=benchmark,ledger \
- fuchsia-pkg://fuchsia.com/ledger_benchmarks#meta/put.cmx \
- --entry-count=10 --transaction-size=1 --key-size=100 --value-size=100 \
- --refs=off
-```
-
-That would generate a trace result file (default: `/data/trace.json`), which can
-be analysed manually or using special tools.
-
-### Benchmark parameters
-
-\*.tspec files specify the parameters with which benchmark apps are run. You can
-override these by passing the "--append-args" argument to the `trace record`
-tool.
-Commonly used among all the ledger benchmarks are the following parameters:
-
-* `entry-count` for the number of entries to perform operations on
-* `unique-key-count` if the number of operations and the number of entries
- differ (i.e. some entries are overwritten), this denotes the number of unique
- entries in the page
-* `key-size` for the size of the key (in bytes)
-* `value-size` for the size of the value (in bytes)
-* `refs` with the values `on` or `off` for the reference strategy: if set to
- `on`, entries will be put using `CreateReference`/`PutAsReference`, otherwise
- they will be treated as inline entries.
-* `commit-count` for the number of commits made to the page
-* `transaction-size` for the number of operations in a single transaction
-
-Unless the name of the benchmark suggest otherwise, default values are:
-* `100` entries
-* key size `100`
-* value size `1000`
-Benchmarks under `sync` and `convergence` use smaller number of entries and
-smaller value size.
-
-### Benchmarks using sync
-
-Some benchmarks exercise cloud synchronization using `cloud_provider_firestore`.
-
-To run these, follow the [cloud sync set-up instructions] to set up a Firestore instance,
-configure the build environment and obtain the sync parameters needed below.
-
-Then, run the selected benchmark as follows:
-
-```sh
-trace record --spec-file=/pkgfs/packages/ledger_benchmarks/0/data/sync.tspec
-```
-
-### A note regarding benchmark apps
-Since the benchmark apps are designed to be used with tracing, running them
-without a tracing will not generate any results.
-
-## List of benchmarks
-
-Some of the benchmark apps have several corresponding tspec files, to exercise
-different possible scenarios of using Ledger. For example, `get_page` benchmark
-is used in `add_new_page.tspec` to emulate creating many pages with different
-IDs, and in `get_same_page.tspec` to create several connections to the same
-page.
-
-### Local benchmarks
-* __Get page__: How long does it take to establish a new page connection?
- * `add_new_page.tspec`: connection to the new page with previously unused
- ID.
- * `add_new_page_precached.tspec`: same as above, but waits for a precached
- Ledger Page to be ready before each request.
- * `get_same_page.tspec`: several connections to the same page
- * `get_page_id.tspec`: how long does the GetId() call takes on a newly
- created page?
-* __Put__: How long does it take to write data to a page? And how long before the
- client will receive a [PageWatcher notification] about its own change?
- * `put.tspec`: basic case
- * `put_big_entry.tspec`: writing big entries to the page
- * `put_as_reference.tspec`: entries are put as references (CreateReference +
- PutReference)
- * `transaction.tspec`: changes are made in a transaction
-* __Update entry__: How long does it take to update an existing value in Ledger
- (make several Put operations with the same key, but different values)?
- * `update_entry.tspec`: basic case
- * `update_big_entry.tspec`: put an entry of big size, then update its value
- * `update_entry_transactions.tspec`: changes are grouped in transactions
-* __Delete entry__: How long does it take to delete an entry from a page?
- * `delete_entry.tspec`: each entry is deleted separately (outside of a
- transaction)
- * `delete_big_entry.tspec`: same as above, but for big entries
- * `delete_entry_transactions.tspec`: deletions are grouped in transactions
- * `disk_space_cleared_page.tspec`: how much space does ledger take after the
- page was cleared out (all the entries deleted in one transaction)?
-* __Disk space__: How much disk space does ledger use to store pages, objects
- and commits?
- * `disk_space_empty_ledger.tspec`: empty ledger (with no pages)
- * `disk_space_empty_pages.tspec`: ledger containing only empty pages
- * `disk_space_entries.tspec`: ledger with one page containing some entries
- * `disk_space_small_keys.tspec`: same, but with small (10 bytes) keys.
- * `disk_space_updates.tspec`: ledger with one page containing only one
- entry, but long commit history
- * `disk_space_one_commit_per_entry.tspec`: ledger with one page containing
- several entries, each of them added in a separate commit
-
-### Sync benchmarks
-These benchmarks exercise synchronisation and need an ID of a Firestore instance
-passed to them as described [in a previous
-section](README.md#benchmarks-using-sync).
-
-* __Backlog__: How long does it take to download all existing data when
- establishing a new connection to an already populated data?
- * `backlog.tspec`: basic case
- * `backlog_big_entry.tspec`: page contains one entry, but of a big size
- * `backlog_big_entry_updates.tspec`: one big entry, but that was updated several
- times prior to the new connection (commit history)
- * `backlog_many_big_entries.tspec`: page contains several big entries
- * `backlog_many_small_entries.tspec`: many small entries
- * `backlog_small_entry_updates.tspec`: small entry, but a long commit
- history
- * `disk_space_synced_entries.tspec`: how much disk space does ledger take on a
- writer and a reader device, when several entries have been written (in one
- commit) on one device and then downloaded on another?
- * `disk_space_synced_entries_small_keys.tspec`: same, but with small (10
- bytes) keys.
- * `disk_space_synced_updates.tspec`: how much disk space does ledger take on a
- writer and a reader device, when several commits with updates has been made on
- one device and then downloaded on another?
-* __Convergence__: Several devices make concurrent changes to the page. How long does
- it take for all devices to see each other changes?
- * `convergence.tspec`: two devices
- * `multidevice_convergence`: several devices
-* __Fetch__: How long does it take to fetch a [lazy value]?
- * `fetch.tspec`: basic case
- * `fetch_partial_big_entry.tspec`: using FetchPartial (fetch in several
- parts) on a big entry
-* __Sync__: When one device makes changes to the page, how long does it take for
- another one to receive these changes?
- * `sync.tspec`: basic case
- * `sync_big_change.tspec`: syncing a big change (containing several write
- operations)

-// Disk space "general usage" benchmark.
-// This benchmark is used to capture Ledger disk usage over the set of common
-// operations, such as getting a new page, adding several entries to the page,
-// modifying the same entry several times.
-//
-// The emulated scenario is as follows:
-// First, |page_count| pages is requested from ledger. Then each page is
-// populated with |unique_key_count| unique entries, making |commit_count|
-// commits in the process (so if |commit_count| is bigger than
-// |unique_key_count|, some entries get overwritten in subsequent commits,
-// whereas if |commit_count| is smaller than |unique_key_count|, insertion
-// operations get grouped together into the requested number of commits). Each
-// entry has a key size of |key_size| and a value size of |value_size|. After
-// that, the connection to the ledger is closed and the size of the directory
-// used by it is measured and reported using a trace counter event.
-//
-// Parameters:
-// --page-count=<int> number of pages to be requested.
-// --unique-key-count=<int> number of unique keys contained in each page
-// after population.
-// --commit-count=<int> number of commits made to each page.
-// If this number is smaller than unique-key-count, changes will be bundled
-// into transactions. If it is bigger, some or all of the changes will use the
-// same keys, modifying the value.
-// --key-size=<int> size of a key for each entry.
-// --value-size=<int> size of a value for each entry.

-// --refs=(on|off) the reference strategy: on if every value is inserted
-// as a reference, off if every value is inserted as a FIDL array.
-// --update whether operations will update existing entries (put with existing
-// keys and new values)

-# Validation Test Suite for cloud providers
-
-This directory contains implementation-independent tests for implementations of
-the [CloudProvider] interface.
-
-In order to run the tests, run the `cloud_provider_validation_tests` binary with
-the cloud provider implementation exposed to it via the `svc` directory.
-
-We expect that individual cloud provider implementations would develop custom
-launcher applications that configure and run the validation tests against their
-implementation of CloudProvider ([example]).

-### StoryModel
-
-The `StoryModel` FIDL table is used to represent the state of a story.
-`sessionmgr` keeps a separate `StoryModel` in memory for each running story,
-and also persists changes to it onto storage. Mutations to `StoryModel` are
-done using the `StoryMutator` interface and changes from these mutations
-are notified to registered observers (using the `StoryObserver`
-interface).
-
-This directory defines classes that define the control flow for mutating a
-`StoryModel` FIDL table.
-
-The following interfaces are defined:
-
-* `StoryMutator`: Allows clients to issue a series of `StoryModelMutation`
- structs that describe mutations to a `StoryModel`.
-* `StoryObserver`: Used to ready `StoryModel` and observe changes to it.
- Changes to `StoryModel` may happen through `StoryMutator` or, in the
- case of a distributed storage implementation such as Ledger, from sync'ing
- with peers.
-interface. Allows clients to read the current `StoryModel` state, and register
-for updates when the `StoryModel` changes.
-
-Both of the above are abstract base classes to aid in testing: clients that
-wish to mutate and/or observe a `StoryModel` will accept a `StoryMutator`
-or `StoryObserver` as a constructor argument. Making them abstract allows
-injection of test implementations that do not require the full machinery
-introduced by `StoryModelOwner`.
-
-#### `StoryModelOwner` class
-
-`StoryModelOwner` is has its own implementations of `StoryMutator` and
-`StoryObserver`, and coordinates the flow of data from
-`StoryMutators` through a `StoryModelStorage`, applies those changes
-to a `StoryModel` and flows this new model to `StoryObserver` instances.
-It acts as a factory for its own implementations of `StoryMutators` and
-`StoryObservers`.
-
-#### `StoryModelStorage` interface
-
-Supplied to `StoryModelOwner` at the time of its creation, a
-`StoryModelStorage` is responsible for consuming mutation commands and
-updating its persistent storage layer by applying a set of mutation commands,
-as well as notifying of mutations that have been applied. A request to mutate
-does not necessary result in those exact mutations being observed (in the case
-of conflict resolution), nor do observed mutations imply a request was made (in
-the case of a `StoryModel` backed by distributed storage).
-
-A "no-op" StoryModelStorage (one that does not result in any disk-backed
-or other durable storage) would immediately notify of any incoming mutations
-without applying them anywhere. In this case the `StoryModel` would be resident
-in memory only.
-
-#### Flow of Control
-
-Mutation commands flow from anything that has a `StoryMutator` through a
-`StoryModelOwner`, `StoryModelStorage` and are translated into new
-`StoryModels`. From that point forward, observers see the new `StoryModel`
-values.
-
-```
-[some system] -> StoryMutator -> StoryModelOwner | commands
- | | "
- StoryModelStorage | "
- | | "
-[other system] <- StoryObserver <- StoryModelOwner $ model
-```
-
-### Example
-
-The constructor for your average System that both mutates and observes a
-`StoryModel` would look like:
-```
-class Foo : public System {
- public:
- Foo(std::unique_ptr<StoryMutator> mutator,
- std::unique_ptr<StoryObserver> observer, ...);
-};
-```
-
-In production, we will create this by leveraging the `StoryModelOwner` to
-create those dependencies:
-
-```
-// assume StoryModelOwner has already been defined.
-auto foo_system = std::make_unique<Foo>(owner->NewMutator(), owner->NewObserver(), ...);
-```
-
-For testing, we leverage test versions of both:
-```
-auto test_mutator = std::make_unique<TestStoryMutator>();
-auto test_observer = std::make_unique<TestStoryObserver>();
-
-// Retain pointers to both |test_mutator| and |test_observer| so we can trigger
-// behavior and validate side-effects.
-auto mutator_ptr = test_mutator.get();
-auto observer_ptr = test_observer.get();
-auto foo_system = std::make_unique<Foo>(std::move(test_mutator), std::move(test_observer));

-// them.
-//
-// c) New next proposals are also considered for interruption. The

-// should interruption, and, if so, makes further decisions about
-// when and how those interruptions should take place.
-//
-// 2) Storing the FIDL bindings for QueryHandlers and ProposalPublishers.
-//
-// a) ProposalPublishers (for Next Suggestions) can be registered via the
-// RegisterProposalPublisher method.
-//
-// b) QueryHandlers are currently registered through the
-// RegisterQueryHandler method.

-
-### select_variant
-List of "selectors" to request variant builds of certain targets.
-Each selector specifies matching criteria and a chosen variant.
-The first selector in the list to match a given target determines
-which variant is used for that target.
-
-Each selector is either a string or a scope. A shortcut selector is
-a string; it gets expanded to a full selector. A full selector is a
-scope, described below.
-
-A string selector can match a name in
-[`select_variant_shortcuts`](#select_variant_shortcuts). If it's not a
-specific shortcut listed there, then it can be the name of any variant
-described in [`known_variants`](#known_variants) and
-[`universal_variants`](#universal_variants) (and combinations thereof).
-A `selector` that's a simple variant name selects for every binary
-built in the target toolchain: `{ host=false variant=selector }`.
-
-If a string selector contains a slash, then it's `"shortcut/filename"`
-and selects only the binary in the target toolchain whose `output_name`
-matches `"filename"`, i.e. it adds `output_name=["filename"]` to each
-selector scope that the shortcut's name alone would yield.
-
-The scope that forms a full selector defines some of these:
-
- variant (required)
- [string or `false`] The variant that applies if this selector
- matches. This can be `false` to choose no variant, or a string
- that names the variant. See
- [`known_variants`](#known_variants) and
- [`universal_variants`](#universal_variants).
-
-The rest below are matching criteria. All are optional.
-The selector matches if and only if all of its criteria match.
-If none of these is defined, then the selector always matches.
-
-The first selector in the list to match wins and then the rest of
-the list is ignored. So construct more complex rules by using a
-"blacklist" selector with `variant=false` before a catch-all or
-"whitelist" selector that names a variant.
-
-Each "[strings]" criterion is a list of strings, and the criterion
-is satisfied if any of the strings matches against the candidate string.
-
- host
- [boolean] If true, the selector matches in the host toolchain.
- If false, the selector matches in the target toolchain.
-
- testonly
- [boolean] If true, the selector matches targets with testonly=true.
- If false, the selector matches in targets without testonly=true.
-
- target_type
- [strings]: `"executable"`, `"loadable_module"`, or `"driver_module"`
-
- output_name
- [strings]: target's `output_name` (default: its `target name`)
-
- label
- [strings]: target's full label with `:` (without toolchain suffix)
-
- name
- [strings]: target's simple name (label after last `/` or `:`)
-
- dir
- [strings]: target's label directory (`//dir` for `//dir:name`).

-### synthesize_packages
-List of extra packages to synthesize on the fly. This is only for
-things that do not appear normally in the source tree. Synthesized
-packages can contain build artifacts only if they already exist in some
-part of the build. They can contain arbitrary verbatim files.
-Synthesized packages can't express dependencies on other packages.
-
-Each element of this list is a scope that is very much like the body of
-a package() template invocation (see [//build/package.gni](https://fuchsia.googlesource.com/build/+/fb9b46cbb98da8b92fdfd2dc1a8beba0836807e8/package.gni)). That scope

-Each element of the list is one variant, which is a scope defining:
-
- `configs` (optional)
- [list of labels] Each label names a config that will be
- automatically used by every target built in this variant.
- For each config `${label}`, there must also be a target
- `${label}_deps`, which each target built in this variant will
- automatically depend on. The `variant()` template is the

- `default_shared_library_configs` list, respectively) after
- all other defaults (and this variant's configs) have been
- added.
-
- `deps` (optional)
- [list of labels] Added to the deps of every target linked in
- this variant (as well as the automatic `${label}_deps` for
- each label in configs).
-
- `name` (required if configs is omitted)
- [string] Name of the variant as used in
- [`select_variant`](#select_variant) elements' `variant` fields.
- It's a good idea to make it something concise and meaningful when
- seen as e.g. part of a directory name under `$root_build_dir`.
- If name is omitted, configs must be nonempty and the simple names
- (not the full label, just the part after all `/`s and `:`s) of these
- configs will be used in toolchain names (each prefixed by a "-"),
- so the list of config names forming each variant must be unique
- among the lists in `known_variants + extra_variants`.

- `toolchain_args` (optional)
- [scope] Each variable defined in this scope overrides a
- build argument in the toolchain context of this variant.
-
- `host_only` (optional)
- `target_only` (optional)
- [scope] This scope can contain any of the fields above.

-## What is Ledger?
-
-Ledger is a distributed storage system for Fuchsia.
-
-Each application (or more precisely, each [component]) running on behalf of a
-particular user has a separate data store provided and managed by Ledger, and
-vended to a client application by Fuchsia framework through its [component
-context].
-
-The data store for the particular component/user combination is private - not
-accessible to other apps of the same user, and not accessible to other users of
-the same app.
-
-Each data store is transparently **synchronized** across devices of its user
-through a [cloud provider]. Any data operations are made **offline-first** with
-no coordination with the cloud. If concurrent modifications result in a data
-conflict, the conflict is resolved using an app-configurable merge policy.
-
-Each data store is organized into collections exposing a **key-value store** API
-called *pages*. Page API supports storing data of arbitrary size, atomic changes
-across multiple keys, snapshots and modification observers.

-# API Guide
-
-This document describes how to use Ledger for synchronized application storage
-in a client application. The goal of the document is to explain the key concepts
-and the most common operations, not necessarily to cover the entire API surface.
-
-[TOC]
-
-## Connecting to Ledger
-
-The Ledger API is exposed through a [FIDL interface].
-
-Access to Ledger is vended from the `fuchsia::modular::ComponentContext` of the running
-application. Each application component has a separate private data store for
-each user on behalf of which it runs.
-
-|||---|||
-#### C++
-
-``` cpp
-module_context->GetComponentContext(
- component_context_.NewRequest());
-fuchsia::ledger::LedgerPtr ledger;
-ledger.set_error_handler([](zx_status_t status) {
- // Handle ledger and connection errors.
-});
-component_context_->GetLedger(ledger.NewRequest());
-```
-
-#### Dart
-
-``` dart
-moduleContext.getComponentContext(
- componentContext.ctrl.request());
-final LedgerProxy ledger = new LedgerProxy();
-ledger.ctrl.error.then((ProxyError error) {
- // Handle ledger and connection errors.
-});
-componentContext.getLedger(ledger.ctrl.request());
-```
-|||---|||
-
-*** aside
-Note that the Ledger connection is provided through a FIDL *interface request*,
-so it can be immediately used to make requests.
-***
-
-## Working with pages
-
-Data stored in Ledger is grouped into separate independent key-value stores
-called *pages*.
-
-Pages are identified by ids of 16 bytes each. When creating a page, the
-application can pick its id (for example, to create/access a page with a name
-that is fixed and known in advance), or can request a new unique id to be
-generated by Ledger (for example, to create pages that correspond 1-1 to
-business logic objects). Ledger also offers a convenience method `GetRootPage()`
-which retrieves the page with id `[0, 0 ... , 0]`.
-
-|||---|||
-#### C++
-
-``` cpp
-fuchsia::ledger::PagePtr page;
-ledger->GetRootPage(page.NewRequest(),
- [] (fuchsia::ledger::Status status) {
- if (status != fuchsia::ledger::Status::OK) {
- // Handle errors.
- }
-});
-page.set_error_handler([] (zx_status_t status) {
- // Handle connection errors.
-});
-```
-
-#### Dart
-
-``` dart
-final PageProxy page = new PageProxy();
-_ledger.getRootPage(
- page.ctrl.request(), (Status status) {
- if (status != Status.ok) {
- // Handle errors.
- }
-});
-page.ctrl.error.then((ProxyError error) {
- // Handle connection errors.
-}
-```
-|||---|||
-
-## Page API
-
-Each page exposes a key-value store API.
-
-The state of each page changes in commits which form a DAG. This DAG is not
-directly exposed to the developer through the Ledger API, but we mention it as
-it helps to understand how the page operations described below behave.
-
-*** promo
-History of a page can and does diverge when the page is modified concurrently on
-multiple devices (or even locally on separate connections to the same page).
-However, it's important to note that any given local page connection (/page
-proxy) always tracks **one path** through the commit history and only advances
-forward.
-***
-
-### Writing
-
-Values can be written/modified using mutation methods of the Page interface.
-
-There are two ways to write a value into a page:
-
- - directly, passing the value in a FIDL message (that's `Put()` and
- `PutWithPriority()` methods). This is handy, but note that the developer
- needs to ensure that the value does not exceed the maximum payload size of a
- FIDL message.
- - in two steps: first streaming the data to be written to a "reference", and
- then setting the value using the reference. (through a combination of
- `CreateReferenceFromSocket()`, `CreateReferenceFromBuffer()` and
- `PutReference()`. Note that the created reference is temporary and not
- persisted through app restarts - it must be set through `PutReference()`, or
- discarded.
-
-### Reading
-
-In order to ensure that reads across multiple entries (key-value pairs) are
-consistent, read operations are exposed through a snapshot API. Snapshot of the
-page can be obtained:
-
- - directly from the page interface (`GetSnapshot()`), yielding a snapshot
- corresponding to the state of the page tracked by this page connection
- - through the [watcher](#Watch) interface, which when delivering each
- notification allows to also request the snapshot corresponding to the state
- associated with the notification
-
-Once the snapshot is obtained, data can be read using the `GetEntries()` method
-which retrieves multiple entries, or the `Get()` method which retrieves the
-value associated with the particular key.
-
-#### Range queries
-
-The `GetEntries()` method takes a `key_start` argument, allowing the app to
-perform a *range query*. In order to retrieve all entries between two keys, we
-need to call `GetEntries()` with the first key passed as `key_start`, and
-continue reading the paginated response as long as the returned values are in
-the desired range.
-
-### Lazy values
-
-`PutWithPriority()` and `PutReference()` methods allow the app to write a value
-as a *lazy value*. Compared with the default *eager values*, lazy values are not
-guaranteed to be proactively fetched to the local device when the Page syncs to
-the state that contains them. The **keys** of the lazy values are always synced
-eagerly, but the value itself might be missing.
-
-To ensure predictable performance of read operations, `Get()` and `GetEntries`
-methods never retrieve the missing lazy values from the network - these must be
-explicitly requested through a dedicated `Fetch()` method.
-
-### Watch
-
-The client application can register a watcher to be notified of changes to the
-state tracked by the local page connection. As typically we are interested in
-retrieving the initial base state at the moment of registering the watcher,
-the watchers are registered using the `GetSnapshot()` method.
-
-[C++ watcher example], [Dart watcher example].
-
-`GetSnapshot()` takes an optional `key_prefix` parameter, which allows the
-client app to register specifically for change notifications within a particular
-prefix of keys.
-
-### Transactions
-
-Transactions allow the application to make a set of changes that are guaranteed
-to be synced and surfaced atomically. A client application would typically:
-
- - start a transaction
- - get a snapshot of the page state through `GetSnapshot()` or a watcher (see
- below), and read the data
- - make changes through the Page interface
- - commit the transaction
-
-Once a transaction is started, the state of the page tracked on the page
-connection is pinned and won't advance until the transaction is either committed
-or aborted - this ensures that the transaction writes affect precisely the state
-visible on the page snapshot.
-
-There can be only one transaction in progress per `Page` connection, but
-clients can create multiple connections to the same page. Each of these
-connections can run a transaction independently from the others.
-
-*** note
-*Watch and transactions*: As starting a transaction pins the state of the page
-visible on the particular page connection, the client app won't receive any
-watch notifications (for watchers registered on this page connection) while the
-transaction is in progress.
-
-Conversely, on a page connection with registered watchers, a
-`StartTransaction()` call will only return when the app finishes processing all
-pending change notification. This ensures the app knows the base state of the
-page when performing a transaction.
-***
-
-## Conflict resolution
-
-If the page history has diverged and has more than one head, conflict resolution
-will be invoked to merge the heads.
-
-*** aside
-Note that this condition is not associated with any particular local page
-connection - there could be multiple local page connections on different
-divergent heads. Conflict resolution is therefore configured through the Ledger
-connection.
-***
-
-By default, a key-by-key last-one-wins policy is used to merge divergent
-commits, based on best-effort, not-guaranteed-to-be-right, timestamps of each
-commit.
-
-The client might opt for a different merge policy by implementing the
-`ConflictResolverFactory` interface and setting it through a Ledger connection.
-
-Available conflict resolution policies:
-
- - last-one-wins (the default): `LAST_ONE_WINS`
-
- For each entry modified on both sides, `LAST_ONE_WINS` takes the entry from
- the most recent commit; for each entry modified only on one side (e.g.:
- when adding a new key, or when modifying an existing one), the modification
- is carried over. The most recent commit is determined using timestamps
- assigned to the commits by the devices that created them. Note, however that
- these timestamps are not guaranteed to be accurate.
- - custom, invoked only for conflicting (modified on both branches being
- merged) entries: `AUTOMATIC_WITH_FALLBACK`
-
- For all modified keys, if either they are modified only on one side, or
- changed in the same way (added/updated with the same value, or deleted) in
- both sides, `AUTOMATIC_WITH_FALLBACK` applies the change automatically. If,
- however any key is modified on both sides with a non identical change, the
- app gets a callback with all changed entries from both sides (not just the
- conflicting ones).
- - custom, invoked for all merges (even if the entries modified by each branch
- are non-conflicting): `CUSTOM`
-
- Conflicting changes are ignored and there are no merges performed.
-
-
-See also [Conflict Resolution](conflict_resolution.md).
-
-## Synchronization
-
-Synchronization is configured at the Ledger level as described in the [user
-guide](user_guide.md). Once configured, the Ledger will upload local changes,
-and download changes made by other devices. These operations will happen
-automatically in the background, and clients do not have to manage them.

-# Architecture
-
-This document explains the internal architecture of Ledger.
-
-[TOC]
-
-## Overview
-
-The Ledger implementation is logically composed of the following components:
-
- - **Storage** that stores and provides access to the data locally,
- - client components that interact with storage:
- - **Local client** that exposes Ledger FIDL API to locally running apps,
- - **Cloud sync** that synchronizes the Ledger state across devices
-
-
-
-All of these components run together within the Ledger process.
-
-## Storage
-
-*** promo
-Ledger stores data in key-value stores called pages. A page changes in atomic
-commits, each commit adding, removing or modifying one or more entries in the
-key-value store.
-
-The commit history of each page forms a DAG in which each commit has either no
-parents (initial commit), 1 parent (regular commit) or 2 parents (merge commit).
-***
-
-The Storage component persists:
-
- - the commit history of each page
- - immutable storage objects holding the state of each page
- - sync metadata, including synchronization state of each object
-
-The contents of each commit are key-value pairs (entries), stored in a
-B-Tree-like structure with the following main properties:
-
- - entries are ordered by the keys, permitting efficient evaluation of range
- queries
- - tree nodes are immutable, allowing referencing the same node from two (or
- more) different commits and thus avoiding duplicating the state among
- different commits with similar content
- - the B-Tree is history-independent, i.e. given the same set of entries, the
- resulting structure of the tree will be the same, independently of the
- insertion order. This property permits to efficiently compute the diff
- between two given commits.
-
-Storage exposes a key-value API to Local client and creates new storage objects
-and commits in response to modifications the Local client makes. Similarly,
-Storage receives commits and storage objects synced from other devices from
-Cloud Sync.
-
-Code:
-
- - [/bin/ledger/storage], in particular:
- - [/bin/ledger/storage/public] contains the public (exposed to other components) API
- - [/bin/ledger/storage/impl] contains the implementation
- - [/bin/ledger/storage/impl/btree] contains the implementation of the B-tree
-
-## Local client
-
-Local Client exposes a FIDL API to apps running on the device. In response to
-modifications to the key-value store requested by apps connecting to Ledger, it
-makes corresponding calls to Storage.
-
-When notified about a conflict by Storage, Local client resolves it according to
-the policy selected by the client app, calling back to it if necessary - see

-## Cloud sync
-
-Cloud sync is notified by Storage about new locally-produced commits and is

-# Conflict Resolution
-
-This document explains how Ledger handles conflicts.
-
-[TOC]
-
-## Conflicts
-
-Ledger is an offline-first database - devices can naturally diverge when making
-concurrent changes and thus, the change history forms a directed acyclic graph
-(DAG) of [commits](architecture.md#Storage). Whenever the local history DAG has
-more than one head commit, i.e. more than one leaf in the DAG, we call this
-state a **conflict**.
-
-*** aside
-A conflict can be created by **two devices** making a concurrent modification of
-the Ledger state, but also by a **single device** making two concurrent changes
-to the local state - this is usually not desirable, but certainly possible.
-***
-
-Whenever a conflict arises, Ledger by default merges the local heads
-automatically, using an entry-by-entry last-one-wins policy based on
-non-reliable timestamps of the two commits being merged. See the [Merge
-Strategies](#Merge-Strategies) section for more details.
-
-Client apps that want to override this behavior can opt for either one of the
-predefined merging policies or use a custom policy and handle the merges
-themselves, see [Conflict Resolution](api_guide.md#Conflict-resolution) in the
-API Guide.
-
-## Convergence
-
-As the same conflict can be resolved concurrently on two devices, the resulting
-state can once more be different between devices. This can potentially create a
-situation where two or more devices keep creating merge commits that are then
-synced and merged again. This situation is called a **merge storm**.
-
-Ledger employs a number of strategies in order to prevent merge storms:
-
- - a device uploads local changes **only** when the local state is resolved
- (there is a single local head). If the local state is divergent, the device
- first resolves the conflicts and only later uploads the result.
- - identical merge of two commits made concurrently on multiple devices results
- in the exact same commit (as long as the conflict resolver makes the same
- decisions, i.e. is deterministic). This is ensured because commits are
- content-addressed based on the B-tree content and the commit metadata; and
- commit metadata of a merge commit, including the commit timestamp, depends
- only on the parent commits - the timestamp is selected as the biggest of two
- parent timestamps.
- - when merging **two merge commits**, Ledger waits with exponential backoff,
- allowing one device to win the race and have a final say on the resolved state.
- The exponential backoff should occur only if the two devices create
- conflicting merge commits, e.g. if the conflict resolution is not
- deterministic (see below).
-
-## Merge Strategies
-
-For each [page](data_organization.md#Pages), client apps can define a *merge
-strategy*. These strategies determine the behavior of Ledger when a conflict is
-detected, and are appropriate for different situations.
-
-To avoid merge storms (as described above), we ensure that any automatic merge
-strategy is **deterministic**, so that two devices seeing the same conflict
-reach the same resolution.
-
-### Last-one-wins
-
-The *last-one-wins* merge strategy is the default one, i.e. the one applied if
-the client app didn't configure any other strategy. When using this strategy,
-the client app delegates all merging to Ledger and doesn't have to handle
-merges.
-
-The last-one-wins strategy operates by taking, for each conflicting key/value
-pair, the one present in the latest commit, ordered by creation timestamp.
-However, if a key/value pair is modified by one commit only (added, removed, or
-changed value), the modification is taken, regardless of the timestamp.
-
-This strategy is very convenient for applications that use Ledger to store
-independent key/value pairs, as it removes the burden of merging from the
-client application entirely. Storing independent key/value user preferences
-would be a good case for this strategy.
-
-*** aside
-The creation timestamps are generated on each device. Thus, unsynchronized
-clocks or clock drift between devices may result in older values taking
-precedence over new ones.
-
-We think this is fine because:
-* We want a fully automatic merge strategy for developers who don't have
-cross-key consistency needs and want to keep their app simple. Others should
-use the more advanced policies with custom mergers.
-* We could do an "arbitrary-one wins" merge policy and use the ordering of an
-internal ID other than a timestamp. As long as this ID (as the timestamp) is
-fixed for a given commit, then the merge is deterministic and we can have a
-valid merge. It seemed better to us to use a policy that makes sense to users
-in the usual case, rather than a random-looking policy.
-* This merge policy operates per key/value pair. This means that the timestamp
-is used only when a value has been changed on both sides: any merge strategy
-must discard at least one of the two values. We think this case is narrow
-enough that clock synchronization issues would be very limited.
-* This is only at the merge level. No other part of Ledger uses these
-timestamps. In particular, if a user ends up in a case of doing a merge with
-last-one-wins, drifted clocks, and conflicting keys, nothing in Ledger would
-break.
-
-***
-
-### Automatic with fallback
-
-The *automatic with fallback* merge strategy attempts to automatically merge
-commits when no key/value pair conflicts, and defer to a [custom conflict
-resolver](#Custom-conflict-resolvers) when at least one key/value pair
-conflicts.
-
-When using this strategy, client applications need to write a custom conflict
-resolver, but its usage is limited: if the client application modified
-disjointed (different) parts of a page on two devices, the modifications of
-each device will be applied automatically and the custom conflict resolver will
-not be called. However, if an entry was modified on both sides to contain
-different values, then the custom conflict resolver will be called.
-
-This strategy is convenient if a client application stores independent
-key/value pairs, but wants to control how the values are merged when modified on
-both places. For example, when storing a list as value, a client app may want
-to merge the list as to keep the modifications of both sides instead of picking
-only one. This strategy can also be used to prompt the user to choose the
-resolution they want.
-
-### Custom
-
-The *Custom* merge strategy defers to the client app each time there is a
-conflict. Remember, however, that Ledger does not consider a change from
-another device to be conflicting if there were no local changes during the same
-period, and will simply fast-forward the Ledger state.
-
-This strategy is useful when the client app is storing key/value pairs that
-have dependencies that need to be enforced by business-logic.
-
-### Custom conflict resolvers
-
-In order to facilitate convergence, any custom conflict resolution implemented
-by the client app should be **deterministic** - that is, the resulting merge
-commit should depend only on the two commits being merged. This ensures that the
-same conflict resolved concurrently on two devices yields the very same result.
-
-The pair of commits passed to the conflict resolver is ordered deterministically
-by Ledger, so the conflict resolver doesn’t need to be **commutative**.
-
-## Case studies
-
-This section discusses conflict resolution behavior in a number of scenarios.
-
-### Offline
-
-When a device that has been making modifications offline goes back online, the
-device downloads remote modifications first, then resolves any conflicts, and
-only after that uploads its own changes to the cloud. This way the other devices
-that are online and in sync with each other only need to fast-forward to catch
-up with remote changes. We sacrifice sync latency (it takes longer for changes
-from the offline device to be visible to others) for faster convergence and less
-bandwidth spend.
-
-
-
-### Online
-
-When two online devices make a concurrent change (that is, both make their
-changes before seeing changes from the other device), the convergence is ensured
-as long as the conflict resolver is deterministic (see [Custom conflict
-resolvers](#Custom-conflict-resolvers)). When two devices concurrently resolve
-the same conflict, they produce the same resulting merge commit. This commit can
-be then uploaded to the cloud twice, once by each device, but any extra
-occurrences will be ignored by each participant and will not trigger further
-merges.

-# Data in Storage
-
-Storage implements persistent representation of data held in Ledger. Such data
-include:
-
-- commit, value and tree node objects
-- journal entries and metadata
-- information on head commits
-- information on which objects have been synced to the cloud
-- other synchronization metadata, such as the time of the last synchronization
- to the cloud
-
-All data and metadata added in storage are persisted using LevelDB. For each
-[page](data_organization.md#Pages) a separate LevelDB instance is created in a
-dedicated filesystem path of the form:
-`{repo_dir}/{serialization_version}/ledgers/{ledger_dir}/{page_id_base64}/leveldb`.
-
-Additionally, metadata about all pages of a single user are persisted in a
-separate LevelDB instance. This includes information such as the last time a
-page was used.
-
-The rest of the document describes the key and value representation for each row
-created in LevelDB to store each data type.
-
-[TOC]
-
-# Per Page data storage
-
-## Commit objects
-
-- Row key: `commits/{commit_id}`
-- Row value: Contains the creation `timestamp`, `generation` (i.e. length of the
- longest path to the first commit created for this page), `root_node_id` and
- `parent_ids`, as serialized by Flatbuffers (see [commit.fbs]).
-
-## Value and tree node objects
-
-In storage there is no difference in the representation of value and node
-objects. Since these two types of objects can be quite big, they might be split
-in multiple pieces. Each **piece** is serialized in LevelDB as follows:
-
-- Row key: `objects/{object_digest}`
-- Row value: `{object_content}`
-
-For value objects, `{object_content}` is the actual user defined content, while
-for tree nodes, it is the list of node entries (key, object_id and priority),
-references to child nodes, and the node level. Tree node content is serialized
-using Flatbuffers (see [tree_node.fbs]).
-
-Note that when a Ledger user inserts a key-value pair, the key is stored in a
-tree node, while the value is stored separately, as described above.
-
-### Splitting objects in pieces
-
-Value or tree node objects might be split into smaller pieces that are stored
-separately. When processing a large object, its content is fed into a rolling
-hash which determines how the object should be split into chunks. For each such
-chunk, whose size is always between 4KiB and 64KiB, an identifier is computed
-and added in a list. Based on the rolling hash algorithm this list is split into
-index files, containing references (identifiers) towards either chunks of the
-original object's content, or other index files. At the end of the algorithm,
-the data chunks and index files form a tree, where the content of the object is
-stored on the leaves.
-
-See also [split.h] and [split.cc] for more details.
-
-## Journals
-
-Changes in Page (Put entry, Delete entry, Clear page) that have not yet been
-committed are organized in [journals]. A journal can be explicit, when it is
-part of an explicitly created transaction or part of a merge commit, or
-implicit, for any other case. On a system crash all explicit journals are
-considered invalid and once the system restarts they are removed from the
-storage. Implicit ones on the other hand, are immediately committed on system
-restart.
-
-A common prefix for all explicit journal entries (`journals/E`) helps remove
-them all together when necessary, and an additional metadata row, for implicit
-journals only, helps retrieve the ids of the not-yet-committed journals.
-
-Journal entry keys (for both implicit and explicit journals) are serialized in
-LevelDB as:
-
-Row key: `journals/{journal_id}/entry/{user_defined_key}`
-
-`{journal_id}` has an `E` prefix if the journal is explicit or an `I` prefix if
-it's implicit.
-
-- If the journal entry is about adding a new or updating an existing Ledger
-key-value pair, then:
-
- Row value: `A{priority_byte}{object_identifier}`
-
- Where `{priority_byte}` is either `E` if the priority is Eager, or `L` if it's
- Lazy.
-
-- If the journal entry is about removing and existing key-value pair, the value
- is:
-
- Row value: `D`
-
-Moreover, if a journal contains a page clear operation, a row with an empty
-value is added to the journal. If it is present, when the journal is commited,
-the previous state of the page must be discarded.
-
-- Row key: `journals/{journal_id}/C`
-- Row value: (empty value)
-
-### Metadata row for implicit journals
-
-For every implicit journal an additional row is kept in LevelDB:
-- Row key: `journals/implicit_metadata/{journal-id}`
-- Row value: `{base_commit_id}`
-
-`{base_commit_id}` is the parent commit of this journal. Note that implicit
-journals always have a single parent (merge commits cannot be implicit
-journals).
-
-## Head commits
-
-The list of head commits is updated and maintained in storage. For each head a
-separate row is created:
-- Row key: `heads/{commit_id}`
-- Row value: `{creation_timestamp}`
-
-## Synchronization status
-
-### Commits
-A row is added for each commit that has been created locally, but is not yet
-synced to the cloud:
-- Row key: `unsynced/commits/{commit_id}`
-- Row value: `{generation}`
-
-### Value and Tree Node Objects
-Each piece, i.e. part of a value or tree node object, can be in any of the
-following states:
-
-- transient: the object piece has been used in a journal that is not yet committed
-- local: the object piece has been used in a commit, but is still not synced
-- synced: the object piece has been synced to the cloud
-
-For each piece, a status row is stored:
-
-- Row key: `{status}/object_digests/{object_piece_identifier}`
-- Row value: (empty value)
-
-Where status is one of `transient`, `local`, or `synced`.
-
-## Cloud sync metadata
-
-The cloud sync component persists in storage rows with some metadata.
-
-- Row key: `sync_metadata/{metadata_type}`
-- Row value: `{metadata_value}`
-
-Currently, cloud sync only stores a single such line, which contains the
-server-side timestamp of the last commit fetched from the cloud.
-
-
-# Pages metadata storage
-
-Additionally to user-created content and metadata on this content, Ledger
-persists information on Page usage, such as the timestamp of when each page was
-last used. This information is used for page eviction, i.e. removing local
-copies of pages, in order to free up device storage when that is necessary.
-
-Page usage information is stored in a dedicated path: `{repo_dir}/page_usage_db`
-using LevelDB.
-
-## Timestamp of last usage
-For each page that is locally stored on the device a row is created in the
-underlying database:
-
-- Row key: `opened/{ledger_name}{page_id}`
-- Row value: `{timestamp}` or `{0}`
-
-`{timestamp}` is the timestamp from when the given page was last closed. If the
-page is currently open, the value is a 0 timestamp.

-# Data Organization
-
-This document describes recommended practices for structuring data that is
-stored in Ledger. We assume that the reader is already familiar with Ledger [API
-surface](api_guide.md).
-
-[TOC]
-
-## Pages
-
-Data stored in Ledger is grouped into separate independent key-value stores
-called *pages*.
-
-Deciding how to split data into pages has the following implications:
-
- - atomic changes across multiple values are possible only within one page, so
- if there's data that has to be modified together, it must belong to the
- same page
- - the current state of each page is either entirely present or entirely absent
- on disk (save for [lazy values](api_guide.md#lazy-values)), hence splitting
- data into multiple pages allows granular optimization of which data to keep
- on disk on each device
-
-There are no restrictions on how many pages a client application can use.
-
-## Entries
-
-Each page stores an ordered list of key-value pairs, also called *entries*.
-
-Both keys and values are arbitrary byte arrays - the client application is free
-to construct the keys and values as needed based on their needs, but see some
-guidance below.
-
-### Key ordering
-
-Entries are sorted by key in the lexicographic order of the byte array. Entry
-retrieval methods always return them in order, it is also possible to use a
-range query to retrieve only a part of the ordered list.
-
-The lexicographic byte array ordering of the keys implies the following caveats:
-
- - **number ordering**: a key of `[1, 0, 0]` is ordered before the key of `[2]`.
- If ordering between the items is important, it is essential to add padding to
- any numbers that are part of the key, so that their width is fixed
- - **string ordering**: ordering of unicode strings in a way that matches human
- expectations is non-trivial and byte-array ordering of utf8/16/32 strings is
- unlikely to yield good results.
-
-### Range queries
-
-The entries stored in a page are sorted by keys, and can be retrieved using
-either exact matching or [range queries](api_guide.md#range-queries).
-
-Because of the range query support, it might be desirable to construct the keys
-in a way that matches the querying needs of the application. For example, a
-messaging application which needs to retrieve only the messages not older than a
-week might wish to structure the data as follows:
-
- - **key**: {timestamp}-{message UUID}
- - **value**: {message content}
-
-*** note
-**Caveat**: as the range queries can currently only yield results in the
-increasing order, in order to retrieve the newest messages, the timestamp needs
-to be constructed as (BIG NUMBER minus the current time).
-***
-
-Then, a [range query](api_guide.md#range-queries) can be used to retrieve the
-messages after the given timestamp.
-
-*** note
-Ledger does not support custom indexes and queries by value. Please do let us
-know about your use cases if this limitation prevents you from adopting Ledger.
-***
-
-### Avoiding collisions
-
-[UUIDs] should be used as part of the entry key in order to avoid unintended
-collisions, where needed. For example, a messaging application might want to
-include an UUID of a message stored in a Ledger entry as part of the entry key,
-in order to avoid collisions between two messages of the same timestamp:
-
- - **key**: {timestamp}-**{message UUID}**
- - **value**: {message content}
-
-## Granularity
-
-Deciding how to split page data into entries has implications on querying
-ability and [conflict resolution](api_guide.md#Conflict-resolution).
-
-If two pieces of data can change **independently** (for example: a name and an
-email of a contact in a contacts app), it is beneficial to put these pieces of
-data in separate entries. Because conflicts are resolved entry-by-entry,
-concurrent modifications of different entries can be automatically merged by the
-default conflict resolution policy.
-
-On the other hand, if two pieces of data are **related** (when one changes, the
-other piece of data needs to change accordingly), we need to either:
-
- - put them in the same entry (and serialize them in the application)
- - put them in separate entries, but use a custom conflict resolution policy
- to preserve the invariants
- - put them in separate entries, but consistently always modify both of them
- together within a [transaction](api_guide.md#transactions)

-`https://console.firebase.google.com/project/<project id>`.
-
-## Configuration
-Go to the [Firebase Console](https://console.firebase.google.com/), and open
-your project.
-
-In `Database / Rules`, paste the rules below and click "Publish".
-
-```
-{
- "rules": {
- ".read": false,
- ".write": false,

-# Life of a Put
-
-This document explains how Ledger works by following the mechanics of a single
-Put operation.
-
-The Putting of a value happens in 2 major stages:
-1. Locally updating the btree to take into account the new key-value.
-2. Synchronizing the new key-value with the cloud and other devices.
-
-## 1. Local update
-The client facing API of Ledger is defined in [ledger.fidl].
-There are multiple methods to do put operations, with slightly different
-semantics. For this example we can use the FIDL method
-``Put(array<uint8> key, array<uint8> value) => (Status status);``.
-
-This FIDL interface is implemented by PageImpl, which takes a generated callback
-type (PutCallback) used to pass the completion status back to the client.
-
-### Storing the Value to disk
-The first step to handling the FIDL call is storing the *value* (which can be
-large, e.g. multiple GB) onto the disk. The value (which can be passed as a byte
-array, a [VMO], or a socket) is wrapped in a DataSource.
-The data in the DataSource is cut in chunks (see [dynamic chunking] for an
-explanation of the idea, and the [splitting implementation] for details).
-The chunks not already on disks are then written to disk.
-
-*** note
-**A note regarding writing to disk:** Ledger writes all its data to disk using
-[LevelDB]. LevelDB's cache makes reading and writing data faster than when using
-the filesystem.
-***
-
-### Draining the pending PageWatcher updates
-Clients can register PageWatchers to observe changes to Pages. Before creating
-the [commit], we drain the pending updates to the PageWatchers registered for
-the given Page connection. After draining the pending updates, we stop the
-BranchTracker from sending new updates until we've handled the change.
-
-If the Put is part of a transaction, we wait for all PageWatchers to have
-handled the updates before continuing to the next step. The PageWatchers say
-that they've handled the OnChange by calling the (generated) OnChangeCallback.
-
-### Journals
-All changes are first written in a Journal before being committed. There are two
-types of journals: *explicit* journals when clients starts a transaction, and
-*implicit* journals when clients do a change without having started a
-transaction first.
-
-Changes in explicit journals are guaranteed to be seen together: a PageSnapshot
-and/or a PageWatcher will either contain/see **all** the changes, or none. If
-for some reason Ledger is unexpectedly closed, any non completed explicit
-transaction is dropped.
-
-In contrast, PageSnapshots and/or PageWatchers may see the individual changes
-from an implicit journal, and if Ledger is unexpectedly closed any in-progress
-implicit journal will be committed during the next startup.
-
-### Finishing a transaction
-When a transaction is completed, a commit is appended to one of the Page's
-heads.
-
-The BranchTracker of the Page connection is informed of this new commit as to
-make sure it tracks that branch and not some other branch. Not doing so would
-make changes seem to “disappear” as clients would see a different branch than
-the one with their change. The BranchTracker then notifies the relevant
-registered Watchers of the change.
-If there are multiple heads, the MergeResolver starts the process of merging the
-heads.

-# Style Guide
-
-This document describes the conventions adopted in Ledger for the relevant
-languages: English and C++.
-
-[TOC]
-
-## English
-
-This section applies to written communication in docs, code comments, commit
-messages, emails, etc.
-
-### ledger vs Ledger vs the ledger vs ...
-
-The project and the resulting application are called "Ledger". It is a proper
-name, hence it is not preceded by an article.
-
-**Do**: *Ledger synchronizes user data across devices*
-
-**Don't**: *~~the Ledger~~ synchronizes user data across devices*
-
-**Don't**: *~~ledger~~ synchronizes user data across devices*
-
-All of the data stored in Ledger on behalf of a user is sometimes referred to as
-this user's ledger. In that case "ledger" is a common name - not capitalized and
-preceded by an article.
-
-**Do**: *each user has a separate ledger*
-
-**Don't**: *each user has ~~separate Ledger~~*
-
-## C++
-
-Ledger, like the rest of Fuchsia, follows [Google C++ Style Guide]. In a few
-cases not covered there, we choose a convention.
-
-### Naming of callback parameters
-
-If there is a need to distinguish callback parameters of a method or a class,
-call them `on_<event>`.
-
-**Do**: `std::function<void(int)> on_done`
-
-**Don't**: ~~`std::function<void(int)> done_callback`~~
-
-### Usage of fxl::StringView vs std::string
-
-This section discusses which string types to use for C++ API arguments.
-
-Use a `fxl::StringView` (non-ref) if the functionality just reads the string:
-`fxl::StringView` can handle any stream of bytes without copies.
-
-Use a `std::string` (non-ref) if:
-
- - the functionality needs to take ownership of the string (it allows users of
- the functionality to `std::move` the string if they don't reuse it
- afterwards), or
- - you need to pass the string over to a function that requires an
- `std::string`.
-
-You might want to use a `const std:string&` (const ref), if you need to call a
-function that itself takes a `const std:string&` (and you cannot or don't want
-to change it to take an `fxl::StringView`).

-# Testing
-
-This document describes different test types used in Ledger.
-
-*** note
-All of the tests run on a Fuchsia device (real or emulated). For the tests below
-we indicate the commands to trigger the execution from the host machine, but the
-execution itself happens on the target.
-***
-
-[TOC]
-
-## TL;DR
-
-```sh
-fx run-test ledger_tests
-```
-
-This command will run the following tests, that are enabled by default:
-
-* [unit tests](#unit-tests)
-* [integration tests](#integration-tests)
-* [local end-to-end tests](#local-e2e)
-* [Firestore cloud provider] unit tests
-
-It will not run the following tests, that need to be configured and executed
-manually:
-
-* [synchronization end-to-end tests](#sync-e2e)
-* [performance tests][benchmarks]
-* [fuzz tests](#fuzz-tests)
-* [Firestore cloud provider] end-to-end tests
-
-## Unit tests
-
-**Unit tests** are low-level tests written against the smallest testable parts
-of the code. Tests for `some_class.{h,cc}` are placed side-by-side the code
-being tested, in a `some_class_unittest.cc` file.
-
-Unit tests are regular [Google Test] tests. Most of them use our own
-[TestLoopFixture] base class to conveniently run them with a fake clock, and
-simulated multi-thread, in order to know when nothing will ever happen again.
-
-All unit tests in the Ledger tree are built into a single `ledger_unittests`
-binary. The binary is self-contained: it contains both the tests and the Ledger
-logic under test linked into a single Google Test binary.
-
-You can run it from the host with:
-
-```sh
-fx run-test -t ledger_unittests ledger_tests
-```
-
-## Integration tests
-
-**Integration tests** are written against client-facing FIDL services exposed by
-Ledger, although these services still run in the same process as the test code.
-
-Integration tests inherit from [IntegrationTest] and are placed under
-[/bin/ledger/tests/integration].
-
-All integration tests in the Ledger tree are built into a single
-`ledger_integration_tests` binary. You can run it from the host:
-
-```sh
-fx run-test -t ledger_integration_tests ledger_tests
-```
-
-*** aside
-Some of the integration tests emulate multiple Ledger instances synchronizing
-data with each other. Through advanced build magic and [testing abstractions],
-these are run both as integration tests (against fake in-memory implementation
-of the cloud provider interface), and as end-to-end synchronization tests
-(against a real server).
-***
-
-## End-to-end tests
-
-**End-to-end tests** are also written against client-facing FIDL services
-exposed by Ledger, but in this case the test code runs in a separate process,
-and connects to Ledger the same way any other client application would do. This
-is the highest-level way of testing that exercises all of the Ledger stack.
-
-### Local tests {#local-e2e}
-
-End-to-end tests not depending on cross-device synchronization are called "local
-end-to-end tests" and are defined in [/bin/ledger/tests/e2e_local]. All local
-end-to-end tests are built into a single `ledger_e2e_local` binary. You can run
-it from the host:
-
-```sh
-fx run-test -t ledger_e2e_local ledger_tests
-```
-
-### Synchronization tests {#sync-e2e}
-
-Synchronization end-to-end tests create multiple local Ledger instances
-configured to synchronize using a cloud provider backed by a real server. The
-cloud provider instances are set up to represent the same virtual user,
-therefore emulating multiple devices synchronizing their Ledger data through the
-real server.
-
-*** note
-Those tests exercise cloud sync against a real server. They are not run by
-default, and you need to follow the instructions below to set up server access
-and run them manually.
-***
-
-<a name="cloud-sync"></a>
-First, ensure you have an instance of the server configured and take note of the
-configuration params (service account credentials file and API key) - in order
-to obtain those, follow the [server configuration] instructions.
-
-Then, create a json sync credentials file file of the following format:
-```javascript
-{
- "api-key": "<API_KEY>",
- "service-account": <SERVICE_ACCOUNT_FILE_CONTENT>
-}
-```
-where <API_KEY> is the api key retrieved from the firebase console, and
-<SERVICE_ACCOUNT_FILE_CONTENT> is the content of the service account credentials
-file.
-
-Then, put the sync credentials file whenever you like, and set the full path to
-it in the GN variable:
-
-```sh
-fx set x64 --args ledger_sync_credentials_file=\"/full/path/to/sync_credentials.json\"
-```
-
-After rebuilding, the credentials file will be automatically embedded in the
-relevant sync test binaries. You will still need to pass the remaining
-parameters (server ID and API key) as command line parameters.
-
-You can now run the tests from the host as follows:
-
-```sh
-fx run-test -t ledger_e2e_sync ledger_tests
-```
-
-## Performance tests
-
-For performance tests, see [benchmarks].
-
-## Fuzz tests
-
-Ledger uses LibFuzzer for fuzz tests. We have a single fuzz package called
-`ledger_fuzzers`. It can be built as follows:
-
-```sh
-fx set x64 --monolith peridot/packages/tests/ledger --fuzz-with asan
-fx full-build
-```
-
-And then run:
-
-```sh
-fx fuzz start ledger
-```
-
-You can refer to the full [fuzzing] instructions for details.

-# User Guide
-
-[TOC]
-
-## Prerequisites
-
-### Disk Storage
-
-Ledger writes all data under `/data/modular/<USER_ID>/LEDGER`. In order for data
-to be persisted, ensure that a persistent partition is mounted under /data. See
-[minfs setup](https://fuchsia.googlesource.com/zircon/+/master/docs/minfs.md).
-
-### Networking
-
-Follow the instructions in
-[netstack](https://fuchsia.googlesource.com/netstack/+/d24151e74c745358b102f4f33a3c5f4d720ddc52/README.md)
-to ensure that your Fuchsia has Internet access.
-
-Run `curl` to verify that it worked:
-
-```
-curl http://example.com
-```
-
-You should see the HTML content of the `example.com` placeholder page.
-
-## Cloud sync
-
-When running in the guest mode, Ledger works locally but does not synchronize data
-with the cloud.
-
-When running in the regular mode, Ledger automatically synchronizes user data
-using a communal cloud instance.
-
-## Reset
-
-Deleting persistent storage (e.g. `rm -rf /data`) does not erase the Ledger
-state in the cloud, which will be synced back the next time a user signs in.
-
-In order to reset the Ledger state in the cloud, visit
-https://fuchsia-ledger.firebaseapp.com/ , sign in with the account you want to
-reset and hit the erase button.
-
-Any device that has local account state synced with the cloud before the erase
-becomes at this point incompatible with the cloud. Ledger will detect this on
-each device upon the next attempt to sync, erase all local data and log the user
-out. The account is usable again immediately after logging back in.
-
-## Debug and inspect
-
-The **Ledger Debug Dashboard** allows you to inspect the local state of the Ledger.
-
-You need to point your browser to the port 4001 of the Fuchsia machine to access
-the dashboard of the current user.
-The dashboard is also accessible from any device connected to the fuchsia machine
-on the same local network.
-
-The dashboard exposes the instances for the current user. When you select an instance,
-it displays its pages. When you select a page, it displays the commits graph, where the root node is
-colored in a different color than the other nodes. When you select a commit,
-it displays its entries (keys, values, priorities), generation (internal Ledger counter)
-and timestamp.

-# Lint
-
-We use clang-tidy to lint C++ code and aim to keep the repository warning-clean.
-The linter is configured in the [.clang-tidy](../.clang-tidy) file.
-
-## How to lint
-
-In order to run the current CL through the linter (assuming the current
-directory is `//peridot`), run:
-
-```
-../scripts/git-file-tidy [--out-dir out/debug-x64]
-```
-
-In order to run the entire repository through the linter, add `--all`. You can
-also add `--fix` in order to automatically generate fixes for some (but not all)
-of the warnings.
-
-## Suppressing warnings
-
-Any warning can be suppressed by adding a `// NOLINT` comment on the line on
-which it occurs. It is also possible to disable the check entirely within Ledger
-repository by editing the [.clang-tidy](../.clang-tidy) file.
-
-## Disabled checks
-
-This list tracks the reasons for which we disabled particular [checks]:
-
- - `clang-analyzer-core.NullDereference`, `clang-analyzer-unix.Malloc` - these
- checks are triggering memory access warnings at rapidjson callsites (despite
- the header filter regex) and we didn't find a more granular way to disable
- them
- - `clang-diagnostic-unused-command-line-argument` - ninja-generated compilation
- database contains the linker argument which ends up unused and triggers this
- warning for every file
- - `misc-noexcept*` - Fuchsia doesn't use C++ exceptions
- - `modernize-deprecated-headers` - Fuchsia uses old-style C headers
- - `modernize-raw-string-literal` - the check was suggesting to convert `\xFF`
- literals, which we'd rather keep in the escaped form.
- - `modernize-return-braced-init-list` - concerns about readability of returning
- braced initialization list for constructor arguments, prefer to use a
- constructor explicitly
- - `modernize-use-auto` - not all flagged callsites seemed worth converting to
- `auto`
- - `modernize-use-equals-delete` - flagging all gtest TEST_F
- - `modernize-use-equals-default` - Ledger chose not to impose a preference for
- "= default"
- - `performance-unnecessary-value-param` - it was flagging view classes
- which we prefer to pass by value
- - `readability-implicit-bool-conversion` - Fuchsia C++ code commonly uses implicit
- bool cast of pointers and numbers

-## Agents
-
-An `Agent` is a singleton-per-session component which runs outside of
-the scope of a Story without any graphical UI.
-
-Agents can schedule tasks (i.e. they can register to be woken up by the
-framework to perform work), and provide services to other modular components.
-
-Any modular component can connect to an agent and access its services (including
-modules, shells, and other agents).
-
-### Environment
-
-An agent is given access to two services provided by the modular framework in
-its incoming namespace:
-
-* `fuchsia.modular.ComponentContext` which gives the agent access to
- functionality which is shared across components run under the modular
- framework (e.g. modules, shells, agents).
-* `fuchsia.modular.AgentContext` which gives agents access to agent specific
- functionality, like creating entity references and scheduling tasks.
-
-An agent is expected to provide two services to the modular framework in its
-outgoing namespace:
-
-* `fuchsia.modular.Agent` which allows the framework to forward connection
- requests from other components and tell the agent to run tasks.
-* `fuchsia.modular.Lifecycle` which allows the framework to signal the agent
- to terminate gracefully.
-
-The aforementioned services enable communication between agents and the modular
-framework, but agents can also expose custom FIDL services to components. For a
-more detailed explanation of the mechanism which enables this service exchange
-see Communication Mechanisms below.
-
-### Lifecycle
-
-For most agents, when a component connects to an agent the framework will give
-the component an `AgentController`. When the connecting component drops the
-`AgentController` connection, and there are no outstanding connections, the
-agent will be killed by the framework.
-
-There are some agents for which the `sessionmgr` maintains an `AgentController`,
-and thus the agent remains alive for the duration of the session. These
-"session" agents also get access to `fuchsia.modular.PuppetMaster` in their
-incoming namespace.
-
-### Communication mechanisms
-
-Components can communicate with agents in two different ways: either by
-connecting to a FIDL service exposed by the agent, or over a `MessageQueue`.
-
-Which communication method is appropriate depends on the semantics of the
-messages being passed. FIDL requires both agent and client to be running,
-whereas message queues allow the life cycles of the sender and receiver to be
-different.
-
-#### FIDL Services
-
-The modular framework will forward a `fuchsia.sys.ServiceProvider` request via
-`fuchsia::modular::Agent.Connect` call, and will also provide the agent with an
-identifier for the client which is requesting the service provider.
-
-Any services added to the service provider will be exposed directly to the
-connecting component.
-
-To illustrate this, consider a module connecting to an agent:
-
-The module calls `ConnectToAgent` on its `ComponentContext`, which contains a
-`ServiceProvider` request as well as an `AgentController` request.
-
-The agent controller request is used by the framework to keep the agent alive
-until the agent controller is closed by the client. If more than one client is
-connected to the same agent, the agent will be kept alive until all agent
-controllers have been closed.
-
-The service provider request is forwarded to the agent, along with a string
-which identifies the client connecting to the agent.
-
-#### Message Queues
-
-Messages sent over message queues are untyped, but allow the life cycles of the
-reader and writer to be decoupled. For example, an agent may provide a module
-with a message queue which it can use to send messages to the agent. The agent
-can then register to be woken up when a message is delivered on the queue.

-## Entities
-
-The Fuchsia entity model facilitates information interchange by defining a
-common interface for _describing_, _referencing_, _accessing_, and _mutating_
-data objects (entities) which are shared between components (modules, agents,
-shells) running in the modular framework. It consists of the following major
-concepts:
-
-* Entities: the data objects shared between components.
-* Entity references: a serializable token which can be used to retrieve an
- `Entity` handle.
-* `Entity`: An interface which gives access to a shared data object.
-* `EntityProvider`: the interface which allows agents to expose entities to
- the system.
-* `EntityResolver`: the Fuchsia API for requesting an `Entity` handle for a
- given reference.
-
-### Lifecycle
-
-The lifecycle of the data backing an `Entity` is controlled by the
-`EntityProvider`. The lifecycle of the `Entity` handle is controlled by
-`sessionmgr`.
-
-#### Entities owned by Agents
-
-Agents don't create `Entity` handles directly. Agents connect to the
-`EntityReferenceFactory` which provides the agent with an entity reference in
-exchange for a `cookie`. The entity reference can then be shared with other
-modular components which can use their `EntityResolver` to dereference it into
-an `Entity` interface.
-
-Calls on that `Entity` interface will then be forwarded to the agent, along with
-the associated cookie.
-
-The agent is thus responsible for storing and providing the entity data,
-associating it with the correct cookie, and optionally handling requests for
-mutating the entity data.
-
-#### Entities owned by a Story
-
-Modules can create entities explicitly via their `ModuleContext` by providing a
-`fuchsia.mem.Buffer` and an associated type. The framework manages the lifecycle
-of such entities by storing them in the story's record. For this reason, when
-the story is deleted, so is the entity. Agents and modules outside the story can
-dereference the entity so long as the story still exists.
-
-#### Entity Resolution
-
-This section describes the internals of entity resolution.
-
-`EntityProviderRunner` implements the `fuchsia::modular::EntityResolver`
-interface, and is also responsible for creating entity references by
-implementing the `fuchsia::modular::EntityReferenceFactory` interface. A single
-instance of the `EntityProviderRunner` manages all the entity providers running
-in the system.
-
-The first step in entity resolution (i.e. the first thing which happens when
-`ResolveEntity` is called) is the runner determines whether the entity is
-provided by an agent or by the modular framework by inspecting the entity
-reference. The runner then asks an `EntityProviderLauncher` to launch the
-appropriate entity provider.
-
-If the entity provider is an agent, an `AgentController` is passed to the
-launcher, and the runner keeps the agent controller alive until the client
-closes the `Entity`.
-
-Each `Entity` request has an associated `EntityController` which the entity
-runner owns. The `EntityController` owns the `AgentController` if the entity
-provider was an agent, and is responsible for forwarding the entity interface
-methods to the entity provider.

-## Intents
-
-An `Intent` is used to instruct a module to perform an action. The intent
-contains the action name, the arguments for the action parameters, and an
-optional handler which explicitly specifies which module is meant to perform the
-action.
-
-### Declaring Actions
-
-Modules can declare which actions they handle, and their associated parameters
-in their [module facet](module_facet.md). The modular framework will then index
-the module and treat it as a candidate for any incoming intents which contain
-the specified action, and don't have an explicit handler set.
-
-### Handling Intents
-
-When an intent is resolved the framework determines which module instance will
-handle it.
-
-The framework then connects to the module's `fuchsia::modular::IntentHandler`
-service, and calls `HandleIntent()`. The framework will connect to the intent
-handler interface each time a new intent is seen for a particular module
-instance, and intents can be sent to modules which are already running. Modules
-are expected to handle the transition between different intents gracefully.
-
-### Example
-
-To illustrate the intended use of intents, consider the following fictional
-example: a new story has been created with a module displaying a list of
-restaurants and the module wants to show directions to the currently selected
-restaurant.
-
-The restaurant module creates an intent with a `com.fuchsia.navigate` action
-with two parameters `start` and `end`, both of type `com.fuchsia.geolocation`
-and passes it to the modular framework via `ModuleContext.AddModuleToStory`.
-
-At this point, the framework will search for a module which has declared support
-for the `com.fuchsia.navigate` action. Once such a module is found, it is added
-to the story and started. The framework then connects to the started module's
-`IntentHandler` service and provides it with the intent.
-
-At this point, the restaurant list module's selected restaurant changes. It
-again creates an intent, with the same action as before but with new location
-arguments and calls `ModuleContext.AddModuleToStory`.
-
-The framework now knows there is already a module instance running (in this case
-`AddModuleToStory` uses the `name` parameter to identify module instances)o
-explicitly specify a which can handle the given action, and connects to its
-`IntentHandler` interface and provides it with the new intent. The navigation
-module can then update its UI to display directions to the new restaurant.
-
-If the restaurant module wanted a specific module (e.g. `Fuchsia Maps`) to
-handle the intent, it would set the `Intent.handler` to the component URL for
-the module.

-## Modules
-
-A `Module` is a component which displays UI and runs as part of a `Story`.
-
-Multiple modules can be composed into a single story, and modules can add other
-modules to the story they are part of. Module's can either embed other modules
-within their own content, or they can delegate visual composition to the
-`StoryShell`.
-
-### Environment
-
-A module is given access to two services provided by the modular framework in
-its incoming namespace:
-
-* `fuchsia.modular.ComponentContext` which gives the agent access to
- functionality which is shared across components run under the modular
- framework (e.g. modules, shells, agents).
-* `fuchsia.modular.ModuleContext` which gives modules access to module
- specific functionality, like adding other modules to its story and creating
- entities.
-
-A module is expected to provide two services to the modular framework in its
-outgoing namespace:
-
-* `fuchsia.ui.app.ViewProvider` which is used to display the module's UI.
-* `fuchsia.modular.Lifecycle` which allows the framework to signal the module
- to terminate gracefully.
-* `fuchsia.modular.IntentHandler` which allows the framework to send
- [intents](intent.md) to the module.
-
-### Lifecycle
-
-A module's lifecycle is bound to the lifecycle of the story it is part of. In
-addition, a given module can have multiple running instances in a single story.
-
-When a module starts another module it is given a module controller which it can
-use to control the lifecycle of the started module.
-
-### Communication Mechanisms
-
-Modules communicate with other modules via intents and entities, and with agents
-via FIDL and message queues.

-# Module Facet
-
-Modules declare their run-time capabilities (e.g. which Intent actions they
-handle) in the module facet of their [component manifest][component-manifest]
-(i.e. their `.cmx` file).
-
-## What is a facet?
-
-Component facets are sections in the component manifest which aren't consumed
-directly by the component manager, but are left to be defined and consumed by
-other parts of Fuchsia. The Modular framework defines a `fuchsia.module` facet
-which module authors use to define module specific properties.
-
-This document describes how to declare a module facet in your component
-manifest.
-
-## Example
-
-The following is an excerpt of a component manifest that defines a module facet.
-
-```
-{
- "facets": {
- "fuchsia.module": {
- "@version": 2,
- "suggestion_headline": "See details about person",
- "intent_filters": [
- {
- "action": "com.google.fuchsia.preview.v1",
- "parameters": [
- {
- "name": "entityToPreview",
- "type": "https://fuchsia.com/types/Friend"
- }
- ]
- }
- ],
- "composition_pattern": "ticker"
- }
- }
-}
-```
-
-This module can be launched using an Intent with the action
-`com.google.fuchsia.preview.v1` action, and a `entityToPreview` parameter of
-type `https://fuchsia.com/types/Friend`.
-
-## Module Facet fields
-
-The module facet is defined under the `fuchsia.module` facet in a component
-manifest. See [example](#example).
-
-* `@version` **unsigned integer** *(required)*
- - Describes the version of the module facet. The fields below indicate
- which minimum `@version` they require.
- - **example**: `2`
-* `composition_pattern`: **string** *(optional)*
- - **minimum `@version`**: 1
- - **possible values:**
- * `ticker`: Show the module at the bottom of the screen underneath another
- module.
- * `comments-right`: show the module to the right of other modules.
- - **example**: `"ticker"`
- - Specifies the compositional pattern that will be used by the story shell
- to display this module along-side other modules in the story. For
- example, the ticker pattern gives a signal to the story shell that the
- module should be placed below another module that it may share a link
- with.
-* `suggestion_headline`: **string** *(optional)*
- - **minimum `@version`**: 2
- - **possible values**: UTF-8 string
- - **example**: `"See details about this person"`
- - A human-readable string that may be used when suggesting this Module.
-* `placeholder_color`: **string** *(optional)*
- - **minimum `@version`**: 2
- - **possible values**: hex color code, leading with a hashtag (`#`)
- - **example**: `"#ff00ff"`
- - Defines the color of the placeholder widget used while the module loads.
-* `intent_filters`: **IntentFilter[]** *(optional)*
- - **minimum `@version`**: 2
- - **possible values**: JSON list of [IntentFilter](#IntentFilter)
- - **example**: See [example](#example).
- - A list of different Intent types this Module is able to handle. An
- action dictates a semantic function this Module implements, as well as
- the role of each of its parameters. When resolving an intent to a
- module, the intent resolver uses an index of these intent filter lists
- to determine which modules can handle an intent.
-
-### IntentFilter
-
-`IntentFilter` is a JSON object used to describe an intent type that a module is
-able to handle. The following describes the fields of the IntentFilter JSON
-object:
-
-* `action`: **string** *(required)*
- - **minimum `@version`**: 2
- - **possible values**: ASCII string
- - The action this module is able to handle.
-* `parameters`: **ParameterConstraint[]** *(required)*
- - **minimum `@version`**: 2
- - **possible values**: JSON List of
- [ParameterConstraint](#ParameterConstraint)
- - Describes the names and types of the parameters required to execute the
- specified action. Parameters are typically passed in as Entities.
-
-### ParameterConstraint
-
-`ParameterConstraint` describes a particular intent parameter's name, and it's
-acceptable type.
-
-* `name`: **string** *(required)*
- - **minimum `@version`**: 2
-* `type`: **string** *(required)*
- - **minimum `@version`**: 2
- - Type that is valid for this parameter.
-
-See [example](#example).

-## Overview
-
-Modular is the application framework for Fuchsia. It manages user experiences by
-composing UI, data, and users from a diverse set of components into logical and
-visual containers called Stories.
-
-The framework defines classes of components to extend user experiences and
-provides software primitives for component composition, communication, task
-delegation, state management and data sharing.
-
-### Requirements to use Modular
-
-Modular supports software written in any language (e.g. Flutter, C++) for any
-Fuchsia supported runtime, as long as it is a Fuchsia Component.
-
-The Modular Framework communicates with components it launches via FIDL, the
-standard IPC mechanism for Fuchsia.
-
-### Extension Points
-
-The framework defines several different classes of components which can be
-implemented by developers to extend the behavior of user experiences:
-
-1. [Modules](module.md) are components which display UI and are visually
- composed in a [Story](story.md).
-1. [Agents](agent.md) are components which run in the background to provide
- services and data to Modules and other Agents.
-1. [Shells](shell.md) manage system UI and mediate user interactions.
-1. [EntityProviders](entity.md) are components which provide access to data
- object (entities) which are shared between components running in modular.
-
-### `basemgr` and `sessionmgr`
-
-After Fuchsia device startup, `basemgr` and `sessionmgr` are processes that
-provide session management, component lifecycle management and state management.
-
-* [`basemgr`](basemgr.md) is responsible for user authentication and
- authorization. It leverages the Base Shell to present UI.
-
-* [`sessionmgr`](sessionmgr.md) is responsible for the lifecycle of Stories,
- Modules and Agents, as well as service and state coordination between them.
- It leverages Session and Story Shells to manage the visual composition of
- these components.

-## Shells
-
-Shells are components which are responsible for composing UI. There are three
-shells:
-
-* `BaseShell` displays UI associated with a device, prior to a session being
- started.
-* `SessionShell` displays the UI associated with a given session (e.g. list of
- stories, settings UI).
-* `StoryShell` displays a single story (i.e. the composition of the modules in
- a story, each story gets its own `StoryShell` instance).
-
-### Environment
-
-A shell is given access to two services provided by the modular framework in its
-incoming namespace:
-
-* `fuchsia.modular.ComponentContext` gives the agent access to functionality
- which is shared across components run under the modular framework (e.g.
- modules, shells, agents).
-* `fuchsia.modular.[Base,Session,Story]ShellContext` gives access to shell
- specific functionality for each type of shell, respectively.
-
-A shell is expected to provide two services to the modular framework in its
-outgoing namespace:
-
-* `fuchsia.modular.[Base,Session,Story]Shell` the modular framework uses to
- communicate requests to display UI.
-* `fuchsia.modular.Lifecycle` allows the framework to signal the shell to
- terminate gracefully.
-
-### Lifecycle
-
-The three shells have varying lifecycles:
-
-* `BaseShell` runs between the time `basemgr` starts up until a session has
- been established, and on demand thereafter to faciliate authentication
- requests.
-* `SessionShell` runs for the duration of a session.
-* `StoryShell` runs while its associated story is running.

-
-A story is a logical container for composing a set of modules.
-

-
-### Presentation

-# How-To: Write a Module in C++
-
-## Overview
-
-A `Module` is a UI component that can participate in a [Story](link to story doc),
-potentially composed of many different `Module`s. A `Module`'s lifecycle is tightly
-bound to the story to which it was added. In addition to the capabilities
-provided to all Peridot components via `fuchsia::modular::ComponentContext`, a `Module` is given
-additional capabilities via its `fuchsia::modular::ModuleContext`.
-
-## `SimpleMod`
-
-`SimpleMod` is a `Module` communicates with `SimpleAgent` via a `fuchsia::modular::MessageQueue`, and
-displays the messages from `SimpleAgent` on screen.
-
-### Mod Initialization
-
-The first step to writing a `Module` is implementing the initializer.
-
-```c++
-#include <lib/component/cpp/startup_context.h>
-#include <lib/app_driver/cpp/module_driver.h>
-#include <lib/async-loop/cpp/loop.h>
-#include <ui/cpp/fidl.h>
-
-namespace simple {
-
-class SimpleModule : fuchsia::ui::viewsv1::ViewProvider {
- public:
- SimpleModule(
- modular::ModuleHost* module_host,
- fidl::InterfaceRequest<fuchsia::ui::viewsv1::ViewProvider> view_provider_request)
- : view_provider_binding_(this) {
- view_provider_binding_.Bind(std::move(view_provider_request));
-}
-
- private:
- modular::ModuleHost* module_host_;
- fidl::Binding<fuchsia::ui::viewsv1::ViewProvider> view_provider_binding_;
- std::set<std::unique_ptr<SimpleView>> views_;
-};
-
-} // namespace simple
-```
-
-The `ModuleHost` provides `SimpleModule` with its `StartupContext` and
-`fuchsia::modular::ModuleContext`.
-
-The `ViewProvider` request allows the system to connect to `SimpleModule`'s view.
-TODO: Update guide to explain view connections.
-
-### Connecting to `SimpleAgent`
-
-In order to provide `SimpleAgent` with a message queue `SimpleModule` first
-needs to connect to the agent via its `fuchsia::modular::ComponentContext`.
-
-```c++
-// Get the component context from the module context.
-modular::fuchsia::modular::ComponentContextPtr component_context;
-module_host->module_context()->GetComponentContext(
- component_context.NewRequest());
-
-// Connect to the agent to retrieve it's outgoing services.
-modular::fuchsia::modular::AgentControllerPtr agent_controller;
-fuchsia::sys::ServiceProviderPtr agent_services;
-component_context->ConnectToAgent("system/bin/simple_agent",
- agent_services.NewRequest(),
- agent_controller.NewRequest());
-```
-
-### Creating a `fuchsia::modular::MessageQueue`
-
-`SimpleModule` needs to create a message queue and retrieve its token to hand
-it over to `SimpleAgent` so it can write messages to it.
-
-```c++
-// Request a new message queue from the component context.
-modular::MessageQueueClient message_queue;
-component_context->ObtainMessageQueue("agent_queue",
- message_queue.NewRequest());
-
-// Get the token for the message queue and send it to the agent.
-message_queue.GetToken(fxl::MakeCopyable(
- [agent_service = std::move(agent_service)](fidl::StringPtr token) {
- agent_service->SetMessageQueue(token);
- }));
-```
-
-### Communicating with `SimpleAgent
-
-In order to receive messages on the newly created message queue, `SimpleModule`
-registers a receiver callback with `MessageQueueClient`. Here, the receiver is a
-lambda that gets called with new messages.
-
-```c++
-// Register a callback with a message queue client that logs any
-// messages that SimpleAgent sends
-message_queue.RegsiterReceiver(
- [](std::string msg, fit::function<void()> ack) {
- ack();
- FXL_LOG(INFO) << "New message: " << msg;
- });
-```
-
-### Running the Module
-
-```c++
-int main(int argc, const char** argv) {
- async::Loop loop(&kAsyncLoopConfigAttachToThread);
- auto context = component::StartupContext::CreateFromStartupInfo();
- modular::ModuleDriver<simple::SimpleModule> driver(context.get(),
- [&loop] { loop.Quit(); });
- loop.Run();
- return 0;
-}
-```
-
-`ModuleDriver` is a helper class that manages the `Module`'s lifecyle. Here it is
-given a newly created `StartupContext` and a callback that will be executed
-when the `Module` exits. `ModuleDriver` requires `SimpleModule` to implement the
-constructor shown above, as well as a `Terminate`:
-
-```c++
-void Terminate(const std::function<void()>& done);
-```
-
-The module is responsible for calling `done` once its shutdown sequence is complete.

-# How-To: Write an fuchsia::modular::Agent in C++
-
-## Overview
-
-An `fuchsia::modular::Agent` is a Peridot component that runs without any direct user interaction.
-The lifetime of a single fuchsia::modular::Agent instance is bounded by its session. It can be
-shared by mods across many stories. In addition to the capabilities provided to all
-Peridot components via `fuchsia::modular::ComponentContext`, an `fuchsia::modular::Agent` is given additional
-capabilities via its `fuchsia::modular::AgentContext`.
-
-See [the simple directory](../simple/) for a complete implementation of
-the `fuchsia::modular::Agent` described here.
-
-## SimpleAgent
-
-`SimpleAgent` is an `fuchsia::modular::Agent` that periodically writes a simple message to
-a `fuchsia::modular::MessageQueue` (a common communication channel).
-
-`SimpleAgent` implements the `Simple` FIDL interface which exposes the
-ability to control which `fuchsia::modular::MessageQueue` the messages will be sent to.
-
-```
-library simple;
-
-[Discoverable]
-interface Simple {
- // Provides the Simple interface with a message queue to which
- // messages will be written periodically.
- 1: SetMessageQueue(string queue_token);
-};
-```
-
-### fuchsia::modular::Agent Initialization
-
-The first step to writing an `fuchsia::modular::Agent` is implementing the initializer:
-
-```c++
-#include <lib/app_driver/cpp/agent_driver.h>
-
-class SimpleAgent {
- public:
- SimpleAgent(AgentHost* const agent_host) {
- ...
- }
-};
-```
-
-The `AgentHost` parameter provides the `fuchsia::modular::Agent` with an `StartupContext`
-and an `fuchsia::modular::AgentContext`.
-
-#### `StartupContext`
-
-`StartupContext` gives the `fuchsia::modular::Agent` access to services provided to it by
-other system components via `incoming_services`. It also allows the `fuchsia::modular::Agent`
-to provide services to other components via `outgoing_services`.
-
-#### `fuchsia::modular::AgentContext`
-
-`fuchsia::modular::AgentContext` is an interface that is exposed to all `Agents`.
-For example, it allows agents to schedule `Task`s that will be executed at
-specific intervals.
-
-`fuchsia::modular::AgentContext` also gives `fuchsia::modular::Agent`s access to `fuchsia::modular::ComponentContext` which is an
-interface that is exposed to all Peridot components (i.e. `fuchsia::modular::Agent` and `Module`).
-For example, `fuchsia::modular::ComponentContext` provides access to `Ledger`, Peridot's cross-device
-storage solution.
-
-### Advertising the `Simple` Interface
-
-In order for the `SimpleAgent` to advertise the `Simple` interface to the system
-it needs to provide it in its `outgoing_services`.
-
-```c++
- SimpleAgent(AgentHost* const agent_host) {
- services_.AddService<Simple>(
- [this](fidl::InterfaceRequest<Simple> request) {
- simple_impl_->Connect(std::move(request));
- });
- }
-
- void Connect(
- fidl::InterfaceRequest<fuchsia::sys::ServiceProvider> outgoing_services) {
- services_.AddBinding(std::move(outgoing_services));
- }
-
- private:
- // The services namespace that the `Simple` service is added to.
- component::ServiceNamespace services_;
-
- // The implementation of the Simple service.
- std::unique_ptr<SimpleImpl> simple_impl_;
-```
-
-In the initializer above, `SimpleAgent` adds the `Simple` service to its `ServiceNamespace`.
- When `SimpleAgent` receives a `Connect` call, it needs to bind the handle held by `request`
- to the concrete implementation in `services_`. It does this by calling
-`AddBinding(std::move(outgoing_services))`.
-
-Now, when a component connects to the `SimpleAgent`, it will be able to connect
-to the `SimpleInterface` and call methods on it. Those method calls will be
-delegated to the `simple_impl_` per the callback given to `AddService()`.
-
-```c++
-class SimpleImpl : Simple {
- SimpleImpl();
- ~SimpleImpl();
-
- void Connect(fidl::InterfaceRequest<Simple> request);
-
- std::string message_queue_token() const { return token_; }
-
- private:
- // |Simple| interface method.
- void SetMessageQueue(fidl::StringPtr queue_token);
-
- // The bindings to the Simple service.
- fidl::BindingSet<Simple> bindings_;
-
- // The current message queue token.
- std::string token_;
-};
-```
-
-The `SimpleImpl` could be part of the `SimpleAgent` class, but it's good practice
-to separate out the implementation of an `fuchsia::modular::Agent` from the implementation(s) of the
-interface(s) it provides.
-
-## Running the fuchsia::modular::Agent
-
-```c++
-int main(int /*argc*/, const char** /*argv*/) {
- async::Loop loop(&kAsyncLoopConfigAttachToThread);
- auto context = component::StartupContext::CreateFromStartupInfo();
- modular::AgentDriver<simple_agent::SimpleAgent> driver(
- context.get(), [&loop] { loop.Quit(); });
- loop.Run();
- return 0;
-}
-```
-
-`AgentDriver` is a helper class that helps manage the `fuchsia::modular::Agent` lifecycle. Here
-it is given a newly created `StartupContext` and a callback that will be
-executed when the `fuchsia::modular::Agent` exits. `AgentDriver` requires `SimpleAgent` to
-implement three methods, one of which is `Connect` which was shown above.
-
-The other two are:
-
-```c++
-void RunTask(const fidl::StringPtr& task_id,
- const std::function<void()>& done) {
- done();
-}
-
-void Terminate(const std::function<void()>& done) { done(); }
-```
-
-`RunTask` is called when a task, scheduled through `fuchsia::modular::AgentContext`'s `ScheduleTask`,
-is triggered.
-
-`Terminate` is called when the framework requests `fuchsia::modular::Agent` to
-exit gracefully.
-
-## Connecting to SimpleAgent
-
-To connect to the `SimpleAgent` from a different component:
-
-```c++
-// The agent is guaranteed to stay alive as long as |agent_controller| stays in scope.
-fuchsia::modular::AgentControllerPtr agent_controller;
-fuchsia::sys::ServiceProviderPtr agent_services;
-SimpleServicePtr agent_service;
-component_context->ConnectToAgent(agent_url,
- agent_services.NewRequest(),
- agent_controller.NewRequest());
-ConnectToService(agent_services.get(), agent_service.NewRequest());
-agent_service->SetMessageQueue(...);
-```
-
-Here the component context is asked to connect to the fuchsia::modular::Agent at `agent_url`, and is
-given a request for the services that the `SimpleAgent` will provide via `agent_services`,
-and a controller for the `fuchsia::modular::Agent` via `agent_controller`.
-
-Then the client connects to the `Simple` interface by invoking `ConnectToService` with
-a request for a new `SimpleServicePtr`. This interface pointer can be used immediately
-to provide the agent with the token for the `fuchsia::modular::MessageQueue` to send messages to.
-
-See the [SimpleModule](how_to_write_a_mod.md) guide for a more in-depth example.

-# todo (headless)
-
-Example module that uses Ledger to store internal data.
-
-To run the module, run:
-
-```
-basemgr --base_shell=dev_base_shell --session_shell=dev_session_shell --session_shell_args=--root_module=example_todo_headless
-```
-
-This is a headless module, taking no input and writing the output to stdout.
-
-The module keeps a list of todo items in a Ledger page, randomly adds and
-removes items, and prints the state after each modification. Items generated by
-each instance are tagged with a unique tag. To observe the application running
-on multiple devices and synchronizing the state using Ledger, [set up Cloud
-Sync](https://fuchsia.googlesource.com/ledger/+/HEAD/docs/user_guide.md#Setup)
-and run the module on each device.
-
-Example output:
-
-```
-[00053.199] 02933.02949> --- To Do ---
-[00053.199] 02933.02949> [ 18355 ] write a spec for the law of gravity

-// This file provides a tool to serialize arbitrary data structures
-// into JSON, and back. It specifically supports serialization of FIDL
-// data (structs, arrays, maps, and combinations thereof), but FIDL is
-// not a requirement. For example, support for STL containers in
-// addition to FIDL containers is easy to add once we need it.
-//
-// We use JSON as the serialization format to store structured values
-// (and at times also structured keys) in the ledger.
-//
-// The design is inspired by Sun RPC's XDR, specifically the definiton
-// of "filters". A filter function takes an operation and a data
-// pointer, and depending on the operation parameter either serializes
-// or deserializes the data. There is one such filter function for
-// every data type. A filter for a simple data type does different
-// things for serialization and deserialization, so having a single
-// one for both operations instead of two separate functions barely
-// reduces code size. However, the efficiency of this design shows in
-// composition: A filter for a struct can be written by simply calling
-// the filters for each field of the struct and passing the operation
-// parameter down. Thus, a filter function for a struct is half the
-// code size of a pair of serialization/deserialization functions.
-//
-// NOTES:
-//
-// XDR is not sync: Although the XDR operation can be applied to an
-// existing instance of the output end (an existing FIDL struct, or an
-// existing JSON AST), full synchronization of the data structure is
-// not guaranteed. All data that exist in the input are added to the
-// output, but not necessarily all data that don't exist in the input
-// are removed from the output. Also, if an error occurs, the output
-// is left in some intermediate state. The most suitable use for
-// updates as of now is to always create a fresh output instance, and
-// if the transciption succeeds, replace the previous instance by the
-// fresh instance.
-//
-// XDR is not about resolving conflicts: If an existing output
-// instance is updated using XDR, we might improve accuracy of
-// removing data that no longer exist, but it is out of the scope of
-// XDR (at least for now) to note that input data conflict with
-// existing output data, and resolving the conflict. Conflict
-// resolution between different versions of data is most likely
-// handled outside XDR.
-//
-// It may be that we will use XDR to support conflict resolution in a
-// data type agnostic way: Instead of defining a conflict resolution
-// between e.g. STL or FIDL data structures, we might instead define
-// XDR filters for them, translate all values to JSON, apply conflict
-// resolution to JSON, and translate the result back.
-//
-// SCHEMA VERSION BACK COMPATIBILITY:
-//
-// The schema of the persistent data is defined in terms of filter functions. In
-// order to support new versions of the code reading versions of the data
-// written by old versions of the code, filter functions are always defined by
-// the client at the top level entry points as lists, never as single functions.
-//
-// The lists contain the filter for the current version of the schema at the
-// top, and filters for reading previous versions into the current version of
-// the code below.
-//
-// Whenever the storage schema changes, a new version of the filter is created
-// and add it to the version list.
-//
-// If the memory schema changes, filters of all versions are adjusted as
-// necessary.
-//
-// Filters that don't change can be reused between versions. If a filter does
-// not change, but the ones that it uses do change, templates can be used to
-// save on code duplication.
-//
-// TODO(mesch): Right now there is no way to ensure that old versions of the
-// code will never read new versions of the data. Support for this is expected
-// from the Ledger, and partially from an upcoming API for explicit version
-// numbers.
-//
-// See comments on XdrFilterType, XdrRead(), and XdrWrite() for details.

-Here is code that helps clients of modular with testing.
-
-When linked against the `//peridot/lib/testing` library target, a test
-application can use the functions in `lib/testing/testing.h` to interact with
-the `TestRunner` service in its environment. This is the standard way to test
-multi-process modular applications; these functions allow a test to declare
-failure, and signal tear down of tests to the TestRunner service.
-
-See [//peridot/tests](/peridot/tests) for more details on running
-tests.

-# AppDriver
-
-App driver is a small framework that supports life cycle management of fidl
-components by implementing the fuchsia::modular::Lifecycle FIDL service.
-
-There are three flavors of app driver: for generic components (AppDriver), for
-components that are run as Modules (ModuleDriver), and for components that are
-run as Agents (AgentDriver). Agents and Modules have additional facets at
-initialization in addition to the asynchronous teardown sequence that fuchsia::modular::Lifecycle
-imposes. See the .h files for details.

-// # Futures
-//
-// A *future* is an object representing the eventual value of an asynchronous
-// operation. They are a useful complement to callback functions or lambdas
-// because they are _composable_: asynchronous operations can be sequentially
-// executed, and an async operation's result can be passed to another async
-// operation, like a Unix pipeline.
-//
-// To use a future:
-//
-// 1. A *producer*, typically an async operation, creates a Future with
-// Future<ResultType>::Create().
-// 2. The producer starts its async operation (e.g. a network request or disk
-// read).
-// 3. The producer synchronously returns the Future to a *consumer*.
-// 4. A consumer attaches a *callback* lambda to the Future using Then(). (The
-// callback can be attached to the future any time after the future is
-// created, before or after the async operation is finished.)
-// 5. Some time later, when the producer's async operation is finished, the
-// producer *completes* the future with a *result* using Complete(result).
-// |result| is 0 to N movable or copyable values, e.g. Complete(),
-// Complete(value), Complete(value1, value2, ...).
-// 6. The consumer's callback is invoked after the future is completed, with the
-// completed result passed as zero or more parameters to the callback.
-//
-// The following example shows a simple use case:
-//
-// Producer:
-//
-// FuturePtr<Bytes> MakeNetworkRequest(NetworkRequest& request) {
-// auto f = Future<Bytes>::Create("NetworkRequest"); // a "trace_name" that's
-// // logged when things go
-// // wrong
-// auto network_request_callback = [f] (Bytes bytes) {
-// f->Complete(bytes);
-// };
-// PerformAsyncNetworkRequest(request, network_request_callback);
-// return f;
-// }
-//
-// Client:
-//
-// FuturePtr<Bytes> f = MakeNetworkRequest();
-// f->Then([] (Bytes bytes) {
-// ProcessBytes(bytes);
-// });
-//
-// ## Chaining and sequencing futures
-//
-// Futures can be composed; this is commonly called "chaining". Methods that
-// attach callbacks, such as Then(), will return another Future: the returned
-// Future is completed once the previous callback has finished executing. For
-// example:
-//
-// Client:
-//
-// ShowProgressSpinner(true);
-// FuturePtr<Bytes> f = MakeNetworkRequest(request);
-// f->AsyncMap([] (Bytes zipped_bytes) {
-// // Use AsyncMap() if your callback wants to return another Future.
-// FuturePtr<Bytes> f = UnzipInBackground(zipped_bytes);
-// return f;
-// })->Map([] (Bytes unzipped_bytes) {
-// // Use Map() if your callback returns a non-future: the callback's return
-// // value will be wrapped up into the returned Future.
-// JPEGImage image = DecodeImageSynchronously(unzipped_bytes);
-// return image;
-// })->AsyncMap([] (JPEGImage image) {
-// FuturePtr<> f = UpdateUIAsynchronously(image);
-// return f;
-// })->Then([] {
-// // Use Then() if your callback returns void. Note that Then() still returns
-// // a Future<>, which will be completed only when your callback finishes
-// // executing.
-// ShowProgressSpinner(false);
-// });
-//
-// ## Memory Management & Ownership
-//
-// FuturePtr is a fxl::RefPtr, which is a smart pointer similar to
-// std::shared_ptr that holds a reference count (refcount). When you call
-// Future::Create(), you are expected to maintain a reference to it. When the
-// Future is deleted, its result and callbacks are also deleted.
-//
-// Each method documents how it affects the future's refcount. To summarize:
-//
-// * Calling Then() on a future does not affect its refcount. This applies to
-// all methods that returns a chained future, such as AsyncMap() and Map().
-// * However, calling Then() on a future will cause that future to maintain a
-// reference to the returned chained future. So, you do not need to maintain a
-// reference to the returned future.
-// * Calling Complete() does not affect the future's refcount.
-// * Unlike Complete(), the closure returned by Completer() _does own_ the
-// future, so you do not need to maintain a reference to the future after
-// calling Completer(). (You do need to maintain a reference to the closure,
-// however.)
-// * Wait(futures) returns a future that every future in |futures| owns, so you
-// do not need to maintain a reference to the returned future. The callback
-// attached to each future in |futures| will also keep a reference to
-// themselves, so that if a future that is Wait()ed on otherwise goes out of
-// scope, the future itself is kept alive.
-//
-// See each method's documentation for more details on memory management.
-//
-// ## Use Weak*() variants to cancel callback chains
-//
-// "Weak" variants exist for all chain/sequence methods (WeakThen(),
-// WeakConstThen(), WeakMap() and WeakAsyncMap()). These are almost identical
-// to their non-weak counterparts but take an fxl::WeakPtr<T> as a first
-// argument. If, at callback invocation time, the WeakPtr is invalid, execution
-// will halt and no future further down the chain will be executed.
-//
-// Example:
-//
-// FuturePtr<> f = MakeFuture();
-// f->WeakThen(weak_ptr_factory.GetWeakPtr(), [] {
-// FXL_LOG(INFO) << "This won't execute";
-// })->Then([] {
-// FXL_LOG(INFO) << "Neither will this";
-// });
-// weak_ptr_factory.InvalidateWeakPtrs();
-// f->Complete();
-//
-// ## Use Wait() to synchronize on multiple futures
-//
-// If multiple futures are running, use the Wait() function to create a
-// Future that completes when all the futures passed to it are completed:
-//
-// FuturePtr<Bytes> f1 = MakeNetworkRequest(request1);
-// FuturePtr<Bytes> f2 = MakeNetworkRequest(request2);
-// FuturePtr<Bytes> f3 = MakeNetworkRequest(request3);
-// Wait<Future<>>("Network requests", {f1, f2, f3})->Then([] {
-// AllNetworkRequestsAreComplete();
-// });
-//
-// See the Wait() function documentation for more details.
-//
-// ## Use Completer() to integrate with functions requiring callbacks
-//
-// Use the Completer() method to integrate with existing code that uses callback
-// functions. Completer() returns an std::function<void(Result)> that, when
-// called, calls Complete() on the future. Re-visiting the first example:
-//
-// Without Completer():
-//
-// FuturePtr<Bytes> MakeNetworkRequest(NetworkRequest& request) {
-// auto f = Future<Bytes>::Create("NetworkRequest");
-// auto network_request_callback = [f] (Bytes bytes) {
-// f->Complete(bytes);
-// };
-// PerformAsyncNetworkRequest(request, network_request_callback);
-// return f;
-// }
-//
-// With Completer():
-//
-// FuturePtr<Bytes> MakeNetworkRequest(NetworkRequest& request) {
-// auto f = Future<Bytes>::Create("NetworkRequest");
-// PerformAsyncNetworkRequest(request, f->Completer());
-// return f;
-// }
-//
-// ## Use error values to propagate errors back to consumers
-//
-// If the future can fail, use a value (or multiple values) that's capable of
-// storing both the error and a successful result to propagate the return value
-// back to the consumer. For example:
-//
-// FuturePtr<std::error_code, Bytes> f = MakeNetworkRequest();
-// f->Then([] (std::error_code error, Bytes bytes) {
-// if (error) {
-// // handle error
-// } else {
-// // network request was successful
-// ProcessBytes(bytes);
-// }
-// });
-//
-// ## fuchsia::modular::Future vs other Futures/Promises
-//
-// If you are familiar with Futures & Promises in other languages, this Future
-// class is intentionally different from others, to better integrate with
-// Fuchsia coding patterns:
-//
-// * NOT THREADSAFE. This will change in the future when thread safety is
-// required, but there are no use cases yet. (YAGNI!)
-// * Support for multiple result values via variadic template parameters. This
-// is required for smooth integration with the fuchsia::modular::Operation
-// class.
-// * Only a single callback can be set via Then(), since move semantics are used
-// so heavily in Fuchsia code. (If multiple callbacks were supported and the
-// result is moved, how does one move the result from one callback to
-// another?)
-// * Multiple callbacks can be set if the callback lambda takes the result via
-// const&. In this case, use ConstThen() to attach each callback, rather
-// than Then(). ConstThen() calls can also be chained, like Then().
-// * There are no success/error callbacks and control flows: all callbacks are
-// "success callbacks".
-// * The traditional reason for error callbacks is to convert exceptions into
-// error values, but Google C++ style doesn't use exceptions, so error
-// callbacks aren't needed.
-// * There's some argument that using separate success/error control flow
-// paths is beneficial. However, in practice, a lot of client code using
-// this pattern don't attach error callbacks, only success callbacks, so
-// errors often go unchecked.
-// * If error values need to be propagated back to the client, use a dedicated
-// error type. (Note that many built-in types may have values that can be
-// interpreted as errors, e.g. nullptr, or 0 or -1.) This also forces a
-// consumer to inspect the type and check for errors.
-// * No cancellation/progress support. Adding cancellation/progress:
-// * adds more complexity to the futures implementation,
-// * can be implemented on top of a core futures implementation for the few
-// cases where they're required, and
-// * typically requires extra cancel/progress callbacks, which adds more
-// control flow paths.
-// * see fxl::CancelableCallback if you need cancellation.
-// * No execution contexts (yet).
-// * There needs to be a comprehensive story about runloops etc first.

-//
-// Held by a unique_ptr<> in the OperationContainer, so instances of derived
-// classes need to be created with new.
-//
-// Advantages of using an Operation instance to implement asynchronous fidl
-// method invocations:
-//
-// 1. To receive the return callback, the interface pointer on which the method
-// is invoked needs to be kept around. It's tricky to place a move-only
-// interface pointer on the capture list of a lambda passed as argument to
-// its own method. An instance is much simpler.
-//
-// 2. The capture list of the callbacks only holds this, everything else that
-// needs to be passed on is in the instance.
-//
-// 3. Completion callbacks don't need to be made copyable and don't need to be
-// mutable, because no move only pointer is pulled from their capture list.
-//
-// 4. Conversion of Handle to Ptr can be done by Bind() because the Ptr is
-// already there.
-//
-// Use of Operation instances must adhere to invariants:
-//
-// * Deleting the operation container deletes all Operation instances in it, and
-// it must be guaranteed that no callbacks of ongoing method invocations are
-// invoked after the Operation instance they access is deleted. In order to
-// accomplish this, an Operation instance must only invoke methods on fidl
-// pointers that are either owned by the Operation instance, or that are owned
-// by the immediate owner of the operation container. This way, when the
-// operation container is deleted, the destructors of all involved fidl
-// pointers are called, close their channels, and cancel all pending method
-// callbacks. If a method is invoked on a fidl pointer that lives on beyond
-// the lifetime of the operation container, this is not guaranteed.

-# We follow these conventions for the organization of the sources, build rules,
-# and packages here:
-#
-# 1. All the binaries used in tests are run through a basemgr invocation
-# configured in modular_tests.json. It usually does not ever make sense to
-# run a test component binary directly, especially not as a test. Therefore,
-# all binaries are deployed in their own packages, so that they are not run
-# automatically by roller scripts. Instead, only the run_modular_tests.sh
-# script is present in /system/test/, which then invokes the test runner,
-# which in turn invokes all the test component binaries in the right
-# configuration.
-#
-# 2. The component binary as well as its package is named with a prefix that
-# tells the test it belongs to, followed by "_test", optionally followed by a
-# name component indicating its function if there are multiple components of
-# the same type in a single test, followed a suffix indicating the component
-# type. This way, all components belonging to the same test are
-# lexicographically sorted together.
-#
-# 3. Common components shared between tests are named after their function
-# followed by a suffix indicating the component type.
-#
-# 4. The suffix that indicates the component type (i.e. the primary service
-# provided by the component) is:
-#
-# - _module -- Module
-# - _agent -- Agent
-# - _session_shell -- SessionShell
-# - _base_shell -- BaseShell
-# - _story_shell -- StoryShell
-# - _service -- FIDL interfaces
-#
-# 5. The main sources of the components are named like the binaries they create.
-#
-#
-# HOW TO ADD A NEW INTEGRATION TEST
-#
-# 1. Add a new subdirectory with rules for the test components (session shells,
-# modules, agents). Define all test components as executable_package()s.
-#
-# 2. Add the newly defined packages for all test components to

-# Testing
-
-Modular has two types of tests, unit tests and integration tests.
-
-## Unit tests
-
-Unit tests are low-level tests written against the smallest testable parts of
-the code. Tests for `some_class.{h,cc}` are placed side-by-side the code being
-tested, in a `some_class_unittest.cc` file.
-
-Unit tests are regular [Google Test] tests, although most of them use our own
-[TestLoopFixture] base class to conveniently run delayed tasks with a
-timeout, ensuring that a failing test does not hang forever.
-
-All Modular unit tests in the peridot tree are built into a single
-`modular_unittests` binary, which can be executed on fuchsia by running
-`/system/test/modular_unittests`.
-
-## Integration tests
-
-Integration tests are written against client-facing FIDL services exposed by
-Modular and run through the [Test Runner] framework in a fuchsia instance
-running on either the build host using QEMU or on a target device.
-
-There are two ways to invoke the test suite, remotely from the build host or
-directly on the fuchsia instance.
-
-### Starting tests remotely from the build host
-
-The test runner discovers the running fuchsia instance automatically, but will
-stop with an error if there is more than one. To fix the problem, specify the
-device name with the `--server` parameter.
-
-In order to run tests from your workstation, a `test_runner` must be running
-under fuchsia. In order to start `test_runner`, you can either:
-
-* Use a gn module to automatically start `test_runner` at fuchsia boot
- time using [boot_test.config](boot_test.config). At build time on your
- workstation, do:
-
-```
-fx set x64 --packages peridot/packages/products/test_modular
-```
-
-* Alternatively, invoke `test_runner` manually after starting fuchsia. In a
- shell on your fuchsia device, do:
-
-```
-run test_runner
-```
-
-Each subdirectory of `peridot/tests` contains one integration test. They
-are all run together by the test runner as specified by the
-[modular_tests.json](modular_tests.json) configuration file:
-
-```
-fx exec garnet/bin/test_runner/run_test \
- --test_file=peridot/tests/modular_tests.json
-```
-
-### Starting the test suite directly under fuchsia
-
-`run_modular_tests.sh` is a command that runs all of the Modular tests. It is
-based on the [Test Runner] framework, but runs the tests without requiring
-`test_runner` to be running under fuchsia.
-
-Run it from the fuchsia shell:
-
-```
-$ /pkgfs/packages/modular_tests/0/test/run_modular_tests.sh
-```
-
-You can also run specific tests by using their name. For example this
-will run only the *link_update* test (as described in
-[modular_tests.json](modular_tests.json)).
-
-```
-$ /pkgfs/packages/modular_tests/0/test/run_modular_tests.sh link_update
-```

-#
-# 1. All the binaries used in tests are run through a basemgr invocation

-#
-# 2. The component binary as well as its package is named with a prefix that

-#
-# 1. Add a new subdirectory with rules for the test components (session shells,

-#
-# 2. Add the newly defined packages for all test components to
-# //peridot/packages/benchmarks/modular.
-#
-# 3. Add a tspec file for the benchmark in the newly added subdirectory.
-#
-# 4. Add an entry for the tspec file to the resources = field of the
-# modular_benchmarks build rule.
-#
-# 5. Add an entry for the test to run_modular_benchmarks.sh.

-This directory contains components and configuration that are used by multiple
-integration tests.
-
-Specifically, there is a module `NullModule` which doesn't do anything and just
-sits there.
-
-It is deployed as its own package and has a module manifest in its package. It
-is added to the configuration of the `fuchsia::modular::ModuleResolver` so it can be started by an
-`fuchsia::modular::Intent`.

-# embed_shell integration test
-
-This test executes the interaction of embedding modules with the story shell.
-
-Modules can start other modules. They can do this either by *embedding* the view
-of the other module into their own view, or by instructing the story runner to
-send the view of the newly started module to the story shell. In that case, the
-story shell is supplied with the view of the started module, an ID for it, the
-ID of the view of the parent module, and the *surface relationship* of the new
-module to its parent module. This information is used to layout the views of the
-modules and provide navigation between them.
-
-A subtlety arises when module one embeds module two, which starts module three,
-but in the story shell. In that case, the story shell doesn't know about the
-direct parent of module three, because it's embedded and its view is not sent to
-the story shell. Instead, module one must be used as the display parent module
-declared to the story shell for the view of module three.
-
-This test executes that behavior. In this test, we use the following concrete
-module implementations:
-
- * *one*: `embed_shell_test_parent_module`
- * *two*: `embed_shell_test_child_module`
- * *three*: `common_null_module`

-Tests that calls to ModuleContext.RemoveSelfFromStory() are handled correctly by the framework.
-
-The session shell starts a story and adds two modules to it. It then signals the
-first module to call ModuleContext.RemoveSelfFromStory and verifies that the
-module is stopped. The session shell then signals the second module to
-ModuleContext.RemoveSelfFromStory, and verifies that the story is stopped as
-well.

-It specifically tests that message queues are persistent between invocations of
-agents, and that a message sent to the message queue of agent while the agent is
-not running can be received by the agent when it's started again.

-# session_shell integration test
-
-This test exercises the APIs exposed to the session shell:
-
-* Create, start, stop, delete stories.
-
-* See existing stories as long as they are not deleted.
-
-* Add modules to existing stories.
-
-* Be notified when story state changes.
-
-* Be notified through SessionShell.AttachView() of a new story view when story
- start is requested by RequestStart().
-
-* Be notified through SessionShell.DetachView() of a story going away.
-
-* StoryRunner tolerates a session shell not responding fast enough to
- SessionShell.DetachView().
-
-* On logout, no DetachView() calls are made for still running stories.
-
-The test code is invoked as a session shell from basemgr and executes a
-predefined sequence of steps, rather than to expose a UI to be driven by user
-interaction, as a session shell normally would. I.e. the test is implemented as a
-session shell component.

-# story_shell test
-
-This test executes the story shell. Below is the sequence of actions and
-verifications. All actions and verifications are driven by the session shell. The
-story shell just responds.
-
-* Create a story and start it.
-* Verify the contents of the link. The first time the story shell is created the
- link content is empty. If the content is empty, write to the link and verify
- those contents when the story shell is restarted.
-* Add a top level module to the story. The module is specified by an intent. The
- intent is resolved to a module that possesses a manifest. The manifest
- specifies a composition pattern.
-* We verify that the story shell receives the notification that the module has
- started, including the manifest.
-* Stop the story. Start the story again.
-* We verify that the story shell receives the same notification about the
- started module as before, including the manifest.
-
-We also verify that the story receives the manifest regardless of how the intent
-we use to add the module is resolved, i.e. regardless of whether it specifies
-the action or the package of the module. For that, we run the whole sequence
-above again, but use intents that specify handlers rather than actions to add
-the modules.
-
-For each event we would like to verify, the story shell writes to TestStore
-using Put(). The session shell uses Get() to register handlers for the keys it
-expects the story shell to Put(), and continues when it has seen all the keys.

-# trigger integration test
-
-This test verifies that Agents are woken up on triggers for:
- 1. New messages on a queue.
- 2. An explicitly deleted message queue.
- 3. A message queue being deleted as part of story tear down.
-
-The general structure of the test is a session shell is created, which
-in turn creates a story and adds the test module to it.
-
-The test module then verifies (1) and (2) by interacting with the
-test agent. It also creates a message queue that it does not delete
-explicitly and hands the token to the session shell.
-
-Once (1) and (2) have been verified, the session shell deletes the story
-and waits for the token it was handed by the module to appear in the
-test store. This signals that the agent was woken by the deletion trigger
-for that queue.

-The modp_b64.c file was modified to remove the inclusion of modp's config.h
-and to fix compilation errors that occur under VC8. The file was renamed
-modp_b64.cc to force it to be compiled as C++ so that the inclusion of
-basictypes.h could be possible.
-
-The modp_b64.cc and modp_b64.h files were modified to make them safe on
-64-bit systems.
-The modp_b64.cc was modified to avoid misaligned read/write on
-little-endian hardware.
-
-modp_b64 was modified to produce base64url.
