- src/, build/, package.json: switch from electerm desktop source to the
electerm-web codebase (same base as electerm-android) — pure-node backend,
no electron APIs
- build/web/build.mjs: vite frontend + esbuild backend bundle into
entry/src/main/resources/resfile/electerm (readable directly at runtime,
no extraction)
- scripts/prepare-node.sh: download hqzing/ohos-node v24.19.0, strip,
install as entry/libs/arm64-v8a/libnode.so
- entry module rewritten as pure ArkTS app:
- Index.ets: Web component + start node backend via
childProcessManager.startNativeChildProcess + HTTP poll + loadUrl
- cpp/node_launcher.c: native child entry that execv()s libnode.so
(memfd fallback if the lib dir is noexec), full boot log
- cpp/node_ctl.c: NAPI kill(pid) for EntryAbility.onDestroy
- scripts/build-web-app.sh: unsigned hvigor assembleApp + hap-sign-tool
signing, entry module only (no web_engine)
- .github/workflows/build-web.yml: CI for dev2 branch

The bare entry/src/main/resources/rawfile ignore rule was for the old electron build's generated rawfile content; dev2 generates nothing there and the Web component loads loading.html from $rawfile. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…s resources Device log (cloud debug) showed the native child spawn worked (cterm:Native_libnode_launcher0, pid 56633) but exited with the launcher's code 40 (script missing): the packaged HAP contains resources/resfile/electerm (plural), Index.ets built .../entry/resource/... - resolveScriptPath(): try both bundleCodeDir shapes, verify with fs.stat - switch Index logging to hilog (console.info is filtered in release — that's why no electerm.Index lines appeared in the device log) - on boot failure, dump node-boot.log tail via hilog for cloud-debug - EntryAbility.onDestroy: actually kill the child (BackendManager), the old LocalStorage lookup always failed - launcher: retry boot log via /data/storage/el2/base junction if the parent's filesDir path is not mounted in the child namespace - build-web-app.sh: extract SDK version with python (BSD sed lacks \+, broke local builds with SDK component missing) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…reen The 13:25 device capture started after spawn and showed only connection- refused polling — child fate unknown, node-boot.log unreachable from the cloud-debug mirror. Make the next round self-diagnosing: - dataDir now uses /data/storage/el2/base/files/electerm-data when the junction exists (mounted in every app process incl. the native child, unlike the parent's sandbox-style filesDir string) - while polling, the overlay shows the latest node-boot.log line (~2s), so a stuck/failing boot is readable from the screen mirror alone - on timeout the overlay shows the last log line (or 'no node-boot.log — child never ran'), and the 800-char tail goes to hilog (electerm.Index) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ode= param) Device round 2: script path fixed (exit 40 gone) but launcher exited 41 — none of the el1-junction candidates matched in the native child's mount namespace. Now: - launcher logs every step to native hilog (electerm.launcher, via libhilog_ndk.z.so) so diagnosis no longer depends on pulling the boot log - node binary candidates: parent-provided node= param (verbatim), dladdr() on Main() (authoritative load path), every arm64 .so dir visible in /proc/self/maps, then the el1 junction layouts - Index.ets logs the libs dir listing (parent-side proof whether the installer extracted the 92MB libnode.so) and passes node= through Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ument execv(libnode.so) and memfd execveat both failed on device (exit 42) — suspected XPM code-integrity / noexec on the bundle mount. New ladder step 6a: exec the system's own signed ld-musl loader with the node binary as its program argument; the loader maps the binary itself (PROT_EXEC mmap, same as dlopen which provably works for app .so files in this process). Also logs node stat() mode/size and the mountinfo options of the containing mount, so noexec/code-integrity is visible in node-boot.log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Device test: execv errno=13 EACCES — even loader-exec. XPM only runs signed code. Build now embeds a code signature in the node ELF via the official binary-sign-tool (openharmony/developtools_hapsigner dist, sha256-pinned download): - cert mode with the APP signing identity when KEYSTORE_PASSWORD/ KEY_PASSWORD are set (CI), self-sign fallback (local) - packed-HAP verification step fails the build if the signature is lost during packaging - entry build-profile: nativeLib.debugSymbol.strip=false so the non-alloc signature section is never stripped - libnode.so is signed in place; restore locally with git checkout -- entry/libs/arm64-v8a/libnode.so Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Third device failure with errno=13: direct execv, exec via the signed system loader, and memfd execveat are ALL refused for the app child — even with the binary cert-signed with the APP identity. XPM blocks the exec syscall for app processes, not the signature. New strategy 1 (nodejs-mobile / WineHua pattern): dlopen the bundled node binary and call its exported embedder entry int node::Start(int argc, char *argv[]) (_ZN4node5StartEiPPc) on a dedicated 32MB-stack thread. OHOS musl's load_library has no PT_INTERP/DF_1_PIE rejection, so the PIE executable loads as a shared object. dlopen is how app code legitimately gets mapped executable (nativespawn loaded this very launcher). Falls back to the exec ladder only if dlopen/dlsym cannot start. Also: chdir(dataDir) before running node; the failure overlay now shows the last 8 boot-log lines so the whole dlopen → dlsym → Start ladder is readable from the screen alone.

…th lost its dir Device log (temp/2026-08-28 15_03_43.log) shows: - node stat mode=100644: hvigor installs libs without the execute bit, execve returns EACCES for that plain reason — the el1 mount is rw,nosuid,nodev,noatime, NOT noexec - loader execv errno=2: findLoader sliced the maps line at 'ld-musl', dropping /lib/ — exec'd a bare filename Fixes: - strategy 2: copy the signed binary into the app-owned el2 data dir (data/bin/node), chmod 0755, exec the copy — size-checked, copied once, kept across restarts - findLoader takes the full last path token of the maps line - chmod failures are logged everywhere now Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Device log (temp/2026-08-28 16_00_16.log): dlopen succeeded, node::Start resolved and entered, then the node thread died of signal 31 (SIGSYS, si_code=1 SYS_SECCOMP) — the app sandbox seccomp filter kills syscalls V8 probes at startup (membarrier / pkey_mprotect / perf_event_open class). The signal was delivered to a handler (OHOS DfxSignalHandler), so it is catchable: install our own SIGSYS handler that logs the trapped syscall number (si_syscall), advances PC past the 4-byte svc instruction, and sets x0 = -ENOSYS. V8/uv treat those probes as optional and degrade gracefully on ENOSYS. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Device: SIGSYS shim worked — node ran deep into libuv and died on assert(fd > STDERR_FILENO) in uv__close. That assert fires when a uv handle ends up on fd 0/1/2, i.e. a stdio slot was closed and reused. - setupStdioForNode(): snapshot the fd table the child was born with into the boot log, then close 0/1/2 and rebuild deterministically (0=/dev/null, 1=2=boot log, log reopened on slot 1) — the nodejs-mobile pattern; no closed or aliased stdio slots can exist - installCrashMarkers(): SIGABRT/SEGV/BUS/ILL/FPE handlers log which signal killed the child before re-raising — an assert-abort now leaves a marker in the boot log instead of a silent end Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Numbers taken from the SDK's asm-generic/unistd.h (aarch64) — the log now reads 'syscall 283 (membarrier)' instead of a bare number. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The nativespawn child runs under a stricter seccomp filter than the app itself — node's libuv aborts there (SIGABRT; the fd>-2 assert in uv__close fires on uv_loop_init's error path when epoll-class syscalls come back ENOSYS from the SIGSYS shim). The MAIN app process runs libuv-class loops of its own (NETSTACK/curl), so node now runs there, the electron-harmony pattern: - libnode_ctl.so startBackend(entryParams): dlopen libnode.so + node::Start on a 32MB-stack pthread in the app process, SIGSYS shim + crash markers, same node-boot.log channel (tag electerm.embed) - Index.ets tries in-process first, falls back to startNativeChildProcess - BackendManager: skip kill for in-process mode (it IS the app) - node-boot.log hilog dump at failure: 800 → 2400 chars Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ilog The in-process run killed the whole app on node's first fatal signal (app closes instantly, no overlay, no dump — the capture window missed it entirely). Now: - fatal signals print the marker to hilog IMMEDIATELY (electerm.embed 'fatal: signal N on tid T') — survives the process - if the signal hit the node thread, park that thread forever instead of dying: the app stays on the loading screen and the 8-line overlay shows the boot-log tail - boot log truncated per attempt so the overlay reflects this run Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The cloud-debug hilog export delivers the OLDEST buffered lines and system noise (~1600 lines/s) flushes the ring long before the 90s boot deadline — every evidence dump so far landed outside the exported window. Now the tail (last 1100 chars) is re-dumped to hilog every ~2s while waiting, so a copy of the ladder + crash marker always sits inside whatever window survives. Failure overlay: 8 → 14 lines.

In the child we rebuilt stdio, so assert/abort text reached the log; in embed mode node's stderr was the app's fd 2 (/dev/null) — abort messages vanished, leaving only the crash marker. Redirect 1/2 onto the boot log (the app runtime logs via hilog, not stdio) so the next run shows the actual assertion text. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…g truncation Device evidence (17:23:49): in-main-process run got all the way to node::Start on tid 30146; the ONLY seccomp-trapped syscall is io_uring_setup (425) → ENOSYS, which libuv handles gracefully (uv__iou_init returns on ringfd<0). Signal 6 abort follows inside node/V8 startup — but its stderr text never reached us: hilog truncates messages at ~140 bytes and ArkWeb stdout junk buries the file tail. - pipe fd 1/2 to a reader thread that logs every line to the boot log AND hilog ([io] prefix, electerm.embed) — assert/abort text arrives live, un-truncated - UV_USE_IO_URING=0 (the one trapped syscall, now skipped up front) - tail dumps split into 110-char chunks, one hilog line each Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The libuv assert (fd > STDERR_FILENO, uv__close core.c:646) names the dying function but not its caller; static analysis of every startup uv__close path (loop init fail paths, io_uring init, signal pipes) came back clean, so make the next device run self-diagnosing: - crashMarkerHandler: backtrace() up to 24 frames, each annotated with dladdr symbol+offset (libnode.so is unstripped — real symbol names are resolvable) and written to the boot log AND hilog, plus full backtrace_symbols_fd dump to the boot log. - Before the stdio pipe: fstat fds 0/1/2 and open /dev/null onto any EBADF fd — a closed std fd at app spawn means pipe() returns fd 0/1, dup2(x,x) no-ops, close() re-closes it, and every later cleanup closes a std fd, tripping exactly this assert. Repair + log the fd layout. - node_ctl built with -fno-omit-frame-pointer so backtrace() walks our frames reliably. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…e of the uv__close assert Device backtrace (b3ba359 run, symbolized against the unstripped libnode.so) finally named the abort caller: uv__close_nocheckstdio ← uv__close (assert fd > STDERR_FILENO) ← uv__iou_init fail path (linux.c:624) ← uv__platform_loop_init ← uv_loop_init (loop.c:79) ← node::tracing::LegacyTracingAgent ctor ← node::tracing::Agent::CreateDefault ← node::V8Platform::Initialize ← node::InitializeOncePerProcessInternal ← node::Start Chain of events: io_uring_setup is seccomp-trapped (SIGSYS), the shim resumed with x0 = -ENOSYS (-38); OHOS musl's syscall() passes raw x0 through WITHOUT upstream musl's __syscall_ret errno-translation, so uv__iou_init received ringfd = -38, passed its 'if (ringfd == -1) return;' guard, failed mmap/epoll_ctl on the bogus fd, and its cleanup called uv__close(-38) → libuv assert → SIGABRT on the node thread. Fix: return exactly -1 (the universal failure value every caller checks) and set errno = ENOSYS (TLS store, async-signal-safe) in BOTH shims — node_ctl.c (main process) and node_launcher.c (native child, which died of the same assert). The tracing-agent loop is the FIRST libuv loop node creates, so this fired before any script ran. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Device log 18_11_18 (521ce7a): the uv__close assert is GONE (the -1 shim fix worked) but the node thread now dies of SIGSEGV inside strlen called from printf machinery, with the interrupted frames being uv__io_uring_setup <- uv__iou_init — i.e. the crash is INSIDE our own SIGSYS handler: its first-sight logging used logWrite (vsnprintf + OH_LOG_Print), which take libc locks; the second seccomp trap fired while the node thread held one, so the handler's own formatting crashed. Classic async-signal-safety violation. - sigsysHandler (node_ctl.c + node_launcher.c): logging is now async-signal-safe — fixed strings + manual decimal into a stack buffer, write(2) only, to the boot log and to fd 2 (the main-process stdio pipe, where the reader thread relays it to hilog in normal context). Per-syscall dedup via a 512-bit bitmap. - stdioReaderThread: filter ArkWeb/chromium framework lines (nweb_, render_, updater, cloud-control, compositor, …) so node's console output, asserts and stack traces are not buried — the on-screen boot overlay shows the boot log tail and was 100% ArkWeb spam last run. - Generated backend entry (build/web/build.mjs): append [backend] milestones directly to node-boot.log (entry running / bundle imported / uncaughtException / unhandledRejection / exit code) — direct file writes bypass stdout entirely, immune to fd-level noise. - CI: setup-java v4 -> v5 (v4 is deprecated).
