# FCL silent-death soak (P13, 2026-10-07)
|
||||
|
||||
User request: soak FCL launches on the Y700 (Magma, Espryt control) to root-cause the "silent
|
||||
Magma death after MobileGL init" seen once in the P13 FCL smoke. User decision afterwards: the
|
||||
cause is FCL's, leave FCL as-is, no MobileGL workaround; recorded as a debt
|
||||
(`../../DEBTS.md`, "FCL game process can die silently").
|
||||
|
||||
## Result
|
||||
|
||||
Every silent death is `ApplicationExitInfo reason=2 (SIGNALED) status=34` - signal 34 is
|
||||
`SIGRTMIN+2`, the wake-up signal of Android libcore's `AsynchronousCloseMonitor`. No tombstone,
|
||||
no kgsl/GPU fault line, no debuggerd output, in any death.
|
||||
|
||||
Mechanism (ftrace `signal_generate` / `signal_deliver` filtered on `sig==34`, plus a 0.5 s
|
||||
sampler of `/proc/<pid>/status` `SigCgt`):
|
||||
|
||||
1. FCL's game process starts with Android's handler set (`SigCgt 0x6e400084f8`, bit 33 = sig 34
|
||||
caught).
|
||||
2. About 0.5 s after FCL logs `Renderer: MobileGLDev...` (JVM start for the game), the whole set
|
||||
is replaced by the JVM's (`SigCgt 0x1005cef`, later `0x2000000001005cef`): sig 34 is no longer
|
||||
caught.
|
||||
3. FCL's own okhttp stack (`Okio Watchdog` thread) times out a blocked read and sends sig 34 to the
|
||||
reading `onPool-worker-N` thread (`AsynchronousCloseMonitor::signalBlockedThreads`, `code=-6`
|
||||
= `SI_TKILL`).
|
||||
4. With the default disposition the kernel takes the fatal fast path: `signal_generate` with no
|
||||
`signal_deliver`, and the whole process dies. In the relaunched launcher process the same
|
||||
watchdog's signals are delivered to libcore's handler (`sa_handler=79a72f3fa0`) and nothing
|
||||
happens.
|
||||
|
||||
Renderer-independent: reproduced with the P13 library on both backends and with the pre-P13 (P12
|
||||
end, `743f4e8e`) library; several deaths happen before MobileGL has logged anything beyond FCL's
|
||||
renderer line. Rate depends on whether FCL's background network read times out in that window
|
||||
(network-dependent), not on the GL library. Untested with non-MobileGL renderers.
|
||||
|
||||
Fix belongs in FCL: save libcore's `SIGRTMIN+2` sigaction before creating the JVM and restore it
|
||||
after (or do not reset that signal). Left for the user.
|
||||
|
||||
## Soak sizes
|
||||
|
||||
| soak | library | runs | deaths (all status=34) |
|
||||
|---|---|---|---|
|
||||
| clean (`soak-p13-clean-summary.txt`, `soak2.sh` with the SigCgt sampler and per-run ftrace) | P13 FCL lib at `c1e985c8` | 30 (22 Magma, 8 Espryt) | 18: Magma 13/22, Espryt 5/8 |
|
||||
| P12 control (`soak-p12-control-summary.txt`) | P12 end `743f4e8e` | 10 Magma | 2 |
|
||||
|
||||
Earlier P13 runs (first 5-run soak) are not counted: two soak scripts were found driving the
|
||||
phone at once and force-stopping each other's runs; `soak2.sh` now takes a lock.
|
||||
|
||||
Per-death evidence kept here for one representative death (clean run 4, Magma): the ftrace
|
||||
excerpt (`run004-magma-ftrace-signal34.txt` - pid 27854 is the dying process's worker, generated
|
||||
with no delivery), the SigCgt transitions (`run004-magma-sigcgt-transitions.txt`) and the logcat
|
||||
lines (`run004-magma-logcat-excerpt.txt`). The full per-run logcat/dmesg/ftrace/exit-info
|
||||
captures stayed in the session scratchpad and were not committed.
|
||||
|
||||
Device restored afterwards: original FCL `libMobileGL.so` (md5 checked) and `config.json`, ftrace
|
||||
signal events and `tracing_on` off, `svc power stayon false`, anland relaunched.
