+# `dumpstate` development tips
+
+## To build `dumpstate`
+
+Do a full build first:
+
+```
+m -j dumpstate
+```
+
+Then incremental ones:
+
+```
+mmm -j frameworks/native/cmds/dumpstate
+```
+
+If you're working on device-specific code, you might need to build them as well. Example:
+
+```
+mmm -j frameworks/native/cmds/dumpstate device/acme/secret_device/dumpstate/ hardware/interfaces/dumpstate
+```
+
+## To build, deploy, and take a bugreport
+
+```
+mmm -j frameworks/native/cmds/dumpstate && adb push ${OUT}/system/bin/dumpstate system/bin && adb shell am bug-report
+```
+
+## To build, deploy, and run unit tests
+
+First create `/data/nativetest`:
+
+```
+adb shell mkdir /data/nativetest
+```
+
+Then run:
+
+```
+mmm -j frameworks/native/cmds/dumpstate/ && adb push ${OUT}/data/nativetest/dumpstate_test* /data/nativetest && adb shell /data/nativetest/dumpstate_test/dumpstate_test
+```
+
+And to run just one test (for example, `DumpstateTest.RunCommandNoArgs`):
+
+```
+mmm -j frameworks/native/cmds/dumpstate/ && adb push ${OUT}/data/nativetest/dumpstate_test* /data/nativetest && adb shell /data/nativetest/dumpstate_test/dumpstate_test --gtest_filter=DumpstateTest.RunCommandNoArgs
+```
+
+## To take quick bugreports
+
+```
+adb shell setprop dumpstate.dry_run true
+```
+
+## To change the `dumpstate` version
+
+```
+adb shell setprop dumpstate.version VERSION_NAME
+```
+
+Example:
+
+```
+adb shell setprop dumpstate.version split-dumpsys && adb shell dumpstate -v
+```
+
+
+Then to restore the default version:
+
+```
+adb shell setprop dumpstate.version default
+```
+
+## Code style and formatting
+
+Use the style defined at the [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html)
+and make sure to run the following command prior to `repo upload`:
+
+```
+git clang-format --style=file HEAD~
+```
+
+## Useful Bash tricks
+
+```
+export BR_DIR=/bugreports
+
+alias br='adb shell cmd activity bug-report'
+alias ls_bugs='adb shell ls -l ${BR_DIR}/'
+
+unzip_bug() {
+ adb pull ${BR_DIR}/$1 && emacs $1 && mv $1 /tmp
+}
+
+less_bug() {
+ adb pull ${BR_DIR}/$1 && less $1 && mv $1 /tmp
+}
+
+rm_bugs() {
+ if [ -z "${BR_DIR}" ] ; then echo "Variable BR_DIR not set"; else adb shell rm -rf ${BR_DIR}/*; fi
+}
+
+```

+SurfaceReplayer Documentation
+===================
+
+[go/SurfaceReplayer](go/SurfaceReplayer)
+
+SurfaceReplayer is a playback mechanism that allows the replaying of traces recorded by
+[SurfaceInterceptor](go/SurfaceInterceptor) from SurfaceFlinger. It specifically replays
+
+* Creation and deletion of surfaces/displays
+* Alterations to the surfaces/displays called Transactions
+* Buffer Updates to surfaces
+* VSync events
+
+At their specified times to be as close to the original trace.
+
+Usage
+--------
+
+###Creating a trace
+
+SurfaceInterceptor is the mechanism used to create traces. The device needs to be rooted in order to
+utilize it. To allow it to write to the device, run
+
+`setenforce 0`
+
+To start recording a trace, run
+
+`service call SurfaceFlinger 1020 i32 1`
+
+To stop recording, run
+
+`service call SurfaceFlinger 1020 i32 0`
+
+The default location for the trace is `/data/SurfaceTrace.dat`
+
+###Executable
+
+To replay a specific trace, execute
+
+`/data/local/tmp/surfacereplayer /absolute/path/to/trace`
+
+inside the android shell. This will replay the full trace and then exit. Running this command
+outside of the shell by prepending `adb shell` will not allow for manual control and will not turn
+off VSync injections if it interrupted in any way other than fully replaying the trace
+
+The replay will not fill surfaces with their contents during the capture. Rather they are given a
+random color which will be the same every time the trace is replayed. Surfaces modulate their color
+at buffer updates.
+
+**Options:**
+
+- -m pause the replayer at the start of the trace for manual replay
+- -t [Number of Threads] uses specified number of threads to queue up actions (default is 3)
+- -s [Timestamp] switches to manual replay at specified timestamp
+- -n Ignore timestamps and run through trace as fast as possible
+- -l Indefinitely loop the replayer
+- -h displays help menu
+
+**Manual Replay:**
+When replaying, if the user presses CTRL-C, the replay will stop and can be manually controlled
+by the user. Pressing CTRL-C again will exit the replayer.
+
+Manual replaying is similar to debugging in gdb. A prompt is presented and the user is able to
+input commands to choose how to proceed by hitting enter after inputting a command. Pressing enter
+without inputting a command repeats the previous command.
+
+- n - steps the replayer to the next VSync event
+- ni - steps the replayer to the next increment
+- c - continues normal replaying
+- c [milliseconds] - continue until specified number of milliseconds have passed
+- s [timestamp] - continue and stop at specified timestamp
+- l - list out timestamp of current increment
+- h - displays help menu
+
+###Shared Library
+
+To use the shared library include these shared libraries
+
+`libsurfacereplayer`
+`libprotobuf-cpp-full`
+`libutils`
+
+And the static library
+
+`libtrace_proto`
+
+Include the replayer header at the top of your file
+
+`#include <replayer/Replayer.h>`
+
+There are two constructors for the replayer
+
+`Replayer(std::string& filename, bool replayManually, int numThreads, bool wait, nsecs_t stopHere)`
+`Replayer(Trace& trace, ... ditto ...)`
+
+The first constructor takes in the filepath where the trace is located and loads in the trace
+object internally.
+- replayManually - **True**: if the replayer will immediately switch to manual replay at the start
+- numThreads - Number of worker threads the replayer will use.
+- wait - **False**: Replayer ignores waits in between increments
+- stopHere - Time stamp of where the replayer should run to then switch to manual replay
+
+The second constructor includes all of the same parameters but takes in a preloaded trace object.
+To use add
+
+`#include <frameworks/native/cmds/surfacereplayer/proto/src/trace.pb.h>`
+
+To your file
+
+After initializing the Replayer call
+
+ replayer.replay();
+
+And the trace will start replaying. Once the trace is finished replaying, the function will return.
+The layers that are visible at the end of the trace will remain on screen until the program
+terminates.
+
+
+**If VSyncs are broken after running the replayer** that means `enableVSyncInjections(false)` was
+never executed. This can be fixed by executing
+
+`service call SurfaceFlinger 23 i32 0`
+
+in the android shell
+
+Code Breakdown
+-------------
+
+The Replayer is composed of 5 components.
+
+- The data format of the trace (Trace.proto)
+- The Replayer object (Replayer.cpp)
+- The synchronization mechanism to signal threads within the Replayer (Event.cpp)
+- The scheduler for buffer updates per surface (BufferQueueScheduler.cpp)
+- The Main executable (Main.cpp)
+
+### Traces
+
+Traces are represented as a protobuf message located in surfacereplayer/proto/src.
+
+**Traces** contain *repeated* **Increments** (events that have occurred in SurfaceFlinger).
+**Increments** contain the time stamp of when it occurred and a *oneof* which can be a
+
+ - Transaction
+ - SurfaceCreation
+ - SurfaceDeletion
+ - DisplayCreation
+ - DisplayDeleteion
+ - BufferUpdate
+ - VSyncEvent
+ - PowerModeUpdate
+
+**Transactions** contain whether the transaction was synchronous or animated and *repeated*
+**SurfaceChanges** and **DisplayChanges**
+
+- **SurfaceChanges** contain an id of the surface being manipulated and can be changes such as
+position, alpha, hidden, size, etc.
+- **DisplayChanges** contain the id of the display being manipulated and can be changes such as
+size, layer stack, projection, etc.
+
+**Surface/Display Creation** contain the id of the surface/display and the name of the
+surface/display
+
+**Surface/Display Deletion** contain the id of the surface/display to be deleted
+
+**Buffer Updates** contain the id of the surface who's buffer is being updated, the size of the
+buffer, and the frame number.
+
+**VSyncEvents** contain when the VSync event has occurred.
+
+**PowerModeUpdates** contain the id of the display being updated and what mode it is being
+changed to.
+
+To output the contents of a trace in a readable format, execute
+
+`**aprotoc** --decode=Trace \
+-I=$ANDROID_BUILD_TOP/frameworks/native/cmds/surfacereplayer/proto/src \
+$ANDROID_BUILD_TOP/frameworks/native/cmds/surfacereplayer/proto/src/trace.proto \
+ < **YourTraceFile.dat** > **YourOutputName.txt**`
+
+
+###Replayer
+
+Fundamentally the replayer loads a trace and iterates through each increment, waiting the required
+amount of time until the increment should be executed, then executing the increment. The first
+increment in a trace does not start at 0, rather the replayer treats its time stamp as time 0 and
+goes from there.
+
+Increments from the trace are played asynchronously rather than one by one, being dispatched by
+the main thread, queued up in a thread pool and completed when the main thread deems they are
+ready to finish execution.
+
+When an increment is dispatched, it completes as much work as it can before it has to be
+synchronized (e.g. prebaking a buffer for a BufferUpdate). When it gets to a critical action
+(e.g. locking and pushing a buffer), it waits for the main thread to complete it using an Event
+object. The main thread holds a queue of these Event objects and completes the
+corresponding Event base on its time stamp. After completing an increment, the main thread will
+dispatch another increment and continue.
+
+The main thread's execution flow is outlined below
+
+ initReplay() //queue up the initial increments
+ while(!pendingIncrements.empty()) { //while increments remaining
+ event = pendingIncrement.pop();
+ wait(event.time_stamp(); //waitUntil it is time to complete this increment
+
+ event.complete() //signal to let event finish
+ if(increments remaing()) {
+ dispatchEvent() //queue up another increment
+ }
+ }
+
+A worker thread's flow looks like so
+
+ //dispatched!
+ Execute non-time sensitive work here
+ ...
+ event.readyToExecute() //time sensitive point...waiting for Main Thread
+ ...
+ Finish execution
+
+
+### Event
+
+An Event is a simple synchronization mechanism used to facilitate communication between the main
+and worker threads. Every time an increment is dispatched, an Event object is also created.
+
+An Event can be in 4 different states:
+
+- **SettingUp** - The worker is in the process of completing all non-time sensitive work
+- **Waiting** - The worker is waiting on the main thread to signal it.
+- **Signaled** - The worker has just been signaled by the main thread
+- **Running** - The worker is running again and finishing the rest of its work.
+
+When the main thread wants to finish the execution of a worker, the worker can either still be
+**SettingUp**, in which the main thread will wait, or the worker will be **Waiting**, in which the
+main thread will **Signal** it to complete. The worker thread changes itself to the **Running**
+state once **Signaled**. This last step exists in order to communicate back to the main thread that
+the worker thread has actually started completing its execution, rather than being preempted right
+after signalling. Once this happens, the main thread schedules the next worker. This makes sure
+there is a constant amount of workers running at one time.
+
+This activity is encapsulated in the `readyToExecute()` and `complete()` functions called by the
+worker and main thread respectively.
+
+### BufferQueueScheduler
+
+During a **BuferUpdate**, the worker thread will wait until **Signaled** to unlock and post a
+buffer that has been prefilled during the **SettingUp** phase. However if there are two sequential
+**BufferUpdates** that act on the same surface, both threads will try to lock a buffer and fill it,
+which isn't possible and will cause a deadlock. The BufferQueueScheduler solves this problem by
+handling when **BufferUpdates** should be scheduled, making sure that they don't overlap.
+
+When a surface is created, a BufferQueueScheduler is also created along side it. Whenever a
+**BufferUpdate** is read, it schedules the event onto its own internal queue and then schedules one
+every time an Event is completed.
+
+### Main
+
+The main exectuable reads in the command line arguments. Creates the Replayer using those
+arguments. Executes `replay()` on the Replayer. If there are no errors while replaying it will exit
+gracefully, if there are then it will report the error and then exit.

+/**
+ * OMX_CONFIG_ANDROID_VENDOR_EXTENSIONTYPE is the structure for an Android vendor extension
+ * supported by the component. This structure enumerates the various extension parameters and their
+ * values.
+ *
+ * Android vendor extensions have a name and one or more parameter values - each with a string key -
+ * that are set together. The values are exposed to Android applications via a string key that is
+ * the concatenation of 'vendor', the extension name and the parameter key, each separated by dot
+ * (.), with any trailing '.value' suffix(es) removed (though optionally allowed).
+ *
+ * Extension names and parameter keys are subject to the following rules:
+ * - Each SHALL contain a set of lowercase alphanumeric (underscore allowed) tags separated by
+ * dot (.) or dash (-).
+ * - The first character of the first tag, and any tag following a dot SHALL not start with a
+ * digit.
+ * - Tags 'value', 'vendor', 'omx' and 'android' (even if trailed and/or followed by any number
+ * of underscores) are prohibited in the extension name.
+ * - Tags 'vendor', 'omx' and 'android' (even if trailed and/or followed by any number
+ * of underscores) are prohibited in parameter keys.
+ * - The tag 'value' (even if trailed and/or followed by any number
+ * of underscores) is prohibited in parameter keys with the following exception:
+ * the parameter key may be exactly 'value'
+ * - The parameter key for extensions with a single parameter value SHALL be 'value'
+ * - No two extensions SHALL have the same name
+ * - No extension's name SHALL start with another extension's NAME followed by a dot (.)
+ * - No two parameters of an extension SHALL have the same key
+ *
+ * This config can be used with both OMX_GetConfig and OMX_SetConfig. In the OMX_GetConfig
+ * case, the caller specifies nIndex and nParamSizeUsed. The component fills in cName,
+ * eDir and nParamCount. Additionally, if nParamSizeUsed is not less than nParamCount, the
+ * component fills out the parameter values (nParam) with the current values for each parameter
+ * of the vendor extension.
+ *
+ * The value of nIndex goes from 0 to N-1, where N is the number of Android vendor extensions
+ * supported by the component. The component does not need to report N as the caller can determine
+ * N by enumerating all extensions supported by the component. The component may not support any
+ * extensions. If there are no more extensions, OMX_GetParameter returns OMX_ErrorNoMore. The
+ * component supplies extensions in the order it wants clients to set them.
+ *
+ * The component SHALL return OMX_ErrorNone for all cases where nIndex is less than N (specifically
+ * even in the case of where nParamCount is greater than nParamSizeUsed).
+ *
+ * In the OMX_SetConfig case the field nIndex is ignored. If the component supports an Android
+ * vendor extension with the name in cName, it SHALL configure the parameter values for that
+ * extension according to the parameters in nParam. nParamCount is the number of valid parameters
+ * in the nParam array, and nParamSizeUsed is the size of the nParam array. (nParamSizeUsed
+ * SHALL be at least nParamCount) Parameters that are part of a vendor extension but are not
+ * in the nParam array are assumed to be unset (this is different from not changed).
+ * All parameter values SHALL have distinct keys in nParam (the component can assume that this
+ * is the case. Otherwise, the actual value for the parameters that are multiply defined can
+ * be any of the set values.)
+ *
+ * Return values in case of OMX_SetConfig:
+ * OMX_ErrorUnsupportedIndex: the component does not support the extension specified by cName
+ * OMX_ErrorUnsupportedSetting: the component does not support some or any of the parameters
+ * (names) specified in nParam
+ * OMX_ErrorBadParameter: the parameter is invalid (e.g. nParamCount is greater than
+ * nParamSizeUsed, or some parameter value has invalid type)
+ *
+ * STRUCTURE MEMBERS:
+ * nSize : size of the structure in bytes
+ * nVersion : OMX specification version information
+ * cName : name of vendor extension
+ * nParamCount : the number of parameter values that are part of this vendor extension
+ * nParamSizeUsed : the size of nParam
+ * (must be at least 1 and at most OMX_MAX_ANDROID_VENDOR_PARAMCOUNT)
+ * param : the parameter values

+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate
+ as of the date such litigation is filed.
+
+ 4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without
+ modifications, and in Source or Object form, provided that You
+ meet the following conditions:
+

+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and

+ (d) If the Work includes a "NOTICE" text file as part of its
+ distribution, then any Derivative Works that You distribute must
+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.
+ Notwithstanding the above, nothing herein shall supersede or modify
+ the terms of any separate license agreement you may have executed
+ with Licensor regarding such Contributions.

+ origin of the Work and reproducing the content of the NOTICE file.
+
+ 7. Disclaimer of Warranty. Unless required by applicable law or
+ agreed to in writing, Licensor provides the Work (and each
+ Contributor provides its Contributions) on an "AS IS" BASIS,
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the
+ appropriateness of using or redistributing the Work and assume any
+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.
