backend/system resolves config and data from $HOME or the OS
equivalent, and Android has neither: buildUserDirPath switches on
runtime.GOOS with cases for darwin, linux and windows and a default
returning errUnsupportedOS. So NewYellowJacketApp failed and main()
called os.Exit(1) about six milliseconds after the JNI bridge came up.
That failure is invisible in all three places anyone would look. There
is no panic, no AndroidRuntime stack and no tombstone, because os.Exit
is not a crash; Go's stdout does not reach logcat, so the slog line
naming the error is discarded; and ActivityManager respawns the process
fast enough that pidof always answers, so a crash-looping app looks
alive.
main() now sets the override before anything asks for a path.
application.Mobile.StoragePath() is the platform's own answer --
getFilesDir() on Android, Application Support on iOS -- and returns ""
on desktop, where UseHomeOverride is a no-op, so this needs no build
tag and changes nothing off mobile. resolveUserDirPath already honours
YJ_HOME on every OS, so there was a seam for it.
The knowledge stays in main(): backend/system gains no import of the
Wails application package, for the same reason backend/events is split
by the indexbuild tag.
UseHomeOverride's two rules are tested because nothing else would
notice them breaking. An empty base does nothing, which is exactly the
desktop case. And an override already set wins, so YJ_HOME still
relocates a sandbox on the one platform that would otherwise decide for
itself.
This is not the end of the port. The app now reaches the database and
takes SIGSYS on the x86_64 emulator -- modernc.org/libc issues a raw
lstat syscall on linux/amd64 and Android's seccomp forbids it. arm64,
which is what ships to phones, has no lstat syscall at all and routes
through fstatat, so it is structurally unaffected. See NOTES.md.
Add a central job registry that library scans and search index builds
report into, so background work is visible instead of buried in the
settings page.
- backend/jobs: registry with per-job ring-buffer logs, capability-driven
controls, and one coalesced JobsChanged snapshot at 4Hz
- pause survives restart via a job_state table; a paused scan is adopted
back on launch and skipped by the soft scan
- top-bar indicator, popover, details drawer and a Jobs page replacing
the config page's scan UI; per-library start/stop retained
- scan timing breakdown moves into the job log, Full rescan to the Jobs
page; delete the orphaned library-manager component
Also add cmd/indexbuild and cmd/indexexport so the explore index can be
built once centrally rather than by every install, which today streams
~205GB from the ListenBrainz spark dump on first run. indexbuild picks
build/refresh/rebuild from index state; the Gitea workflow runs it on
push, weekly, or manually and publishes only when content changed.
fresh-install no longer defaults YJ_HOME under /tmp: it is tmpfs on most
distros, and the import needs ~6GB of real disk.
