status_check.yml stops its E2E matrix at 36 and says the android-37.0 image is why. That is established locally under -gpu host and under ANGLE, and it is not established for CI: runners use -gpu swiftshader_indirect, and the one local measurement of that mode was void for a local reason -- Fedora denies execheap to SwiftShader's JIT, so the emulator died before the guest mattered. What CI does at API 37 has therefore never actually been measured. This is that E2E job with the matrix replaced by workflow_dispatch inputs, so a hypothesis costs a dispatch rather than a commit: renderer, API level, image target, channel, SystemUI disable, boot timeout, whether the suite runs at all, and free-form emulator and Gradle arguments. It triggers on nothing else and gates nothing. It calls .github/scripts/e2e-run.sh rather than forking it, and pins the same disk-size, ram-size, action SHAs and KVM setup as the job it copies, so a run here measures the renderer and not a different device. The watchdog is load-bearing rather than decorative. The emulator action calls killEmulator() from its own catch block, so a run whose emulator never boots is torn down before any script: line executes and leaves nothing behind -- which is the exact failure shape API 37 is suspected of. It starts before the action, samples sys.boot_completed, the surfaceflinger and zygote pids and the hasReadColorBufferDma abort count every 20 s, and keeps a rolling copy of the crash buffer so the last read survives the teardown.

# ---------------------------------------------------------------------------
|
|
# WHAT THIS IS FOR, AND WHY IT IS SEPARATE
|
|
#
|
|
# status_check.yml's E2E matrix stops at API 36 because the android-37.x emulator
|
|
# images abort surfaceflinger inside their own gralloc mapper. That was established
|
|
# locally, under -gpu host and under ANGLE (docs/api-37-emulator-crash.md). It was
|
|
# NOT established on a GitHub runner: CI runs -gpu swiftshader_indirect, and the one
|
|
# local measurement of that mode was void for a purely local reason (Fedora's SELinux
|
|
# denies execheap to SwiftShader's Reactor JIT -- docs/local-emulator.md). So what CI
|
|
# actually does at API 37 is an open question, and this workflow is the instrument for
|
|
# answering it.
|
|
#
|
|
# It is a copy of that E2E job with the matrix replaced by workflow_dispatch inputs,
|
|
# so one hypothesis costs one dispatch rather than one commit. It triggers on nothing
|
|
# else: no push, no pull_request, no schedule. Nothing depends on it and it gates
|
|
# nothing.
|
|
#
|
|
# TWO THINGS THIS DELIBERATELY DOES NOT DO:
|
|
#
|
|
# - It does not fork .github/scripts/e2e-run.sh. That script owns the FAILED-vs-WEDGED
|
|
# split, the SIGQUIT thread dump and the streamed logcat, and it is the copy CI
|
|
# exercises every day. This calls it, exactly as status_check.yml does.
|
|
# - It does not change status_check.yml. If a configuration here turns out to work,
|
|
# the change to the real matrix is proposed separately.
|
|
#
|
|
# THE WATCHDOG IS THE POINT, not a nicety. reactivecircus/android-emulator-runner calls
|
|
# killEmulator() from its own catch block, so a run whose emulator never boots is torn
|
|
# down before a single `script:` line executes -- no probe, no e2e-run.sh, no artifacts,
|
|
# nothing to read afterwards. That is precisely the failure shape API 37 is suspected of.
|
|
# The watchdog therefore starts BEFORE the action, from outside it, and samples the device
|
|
# on its own clock.
