[runtests] Use fmemopen() again. Also replace fbl::unique_ptr with std::unique_ptr. The former is deprecated. This reverts commit 5bcd7e433a8151c58afb009cf5b5e336f43522c0. Reason for revert: All bots have been upgraded. Original change's description: > [runtests] Make runtests-utils-test compatible with earlier versions of macOS. > > -Support for fmemopen(), although a POSIX standard, is only supported > in more recent versions of macOS. > -The WriteSummaryJSON tests now take noticeably longer, so we mark these > tests as 'medium'. > > Tested: Both host and target versions of runtests-utils-test pass. > > Change-Id: Ia3b00eeaab2c339106c8bddebd088b9440b2ceb7 Test: CQ Bug: IN-499 #comment Change-Id: I5cb7e441877e41cfd40f4925ff092e8099d944f0
Zircon is the core platform that powers the Fuchsia OS. Zircon is composed of a microkernel (source in kernel/...) as well as a small set of userspace services, drivers, and libraries (source in system/...) necessary for the system to boot, talk to hardware, load userspace processes and run them, etc. Fuchsia builds a much larger OS on top of this foundation.
The canonical Zircon Git repository is located at: https://fuchsia.googlesource.com/zircon
The Zircon Kernel provides syscalls to manage processes, threads, virtual memory, inter-process communication, waiting on object state changes, and locking (via futexes).
Currently there are some temporary syscalls that have been used for early bringup work, which will be going away in the future as the long term syscall API/ABI surface is finalized. The expectation is that there will be about 100 syscalls.
Zircon syscalls are generally non-blocking. The wait_one, wait_many port_wait and thread sleep being the notable exceptions.
This page is a non-comprehensive index of the zircon documentation.
