* fix(linux): restore Ubuntu 20.04 launch by pinning node-pty glibc symbols (#9902)
The bundled node-pty pty.node is compiled from source in release CI on
ubuntu-latest (glibc 2.39). glibc's 2.32-2.34 libpthread/libutil merge
relocated openpty/forkpty (GLIBC_2.34) and pthread_sigmask (GLIBC_2.32)
into libc under new symbol versions, so the from-source build bound to
versions absent on Ubuntu 20.04 (glibc 2.31). The main process imports
node-pty at startup, so the app crashed on launch. pty.node is the sole
blocker (Electron needs GLIBC_2.25; other native modules <= 2.17).
- Patch node-pty: a .symver shim pins the 3 symbols to their pre-merge
version (GLIBC_2.2.5 x64 / GLIBC_2.17 arm64), and Linux-only ldflags
force libutil.so.1/libpthread.so.0 back into DT_NEEDED. Guarded to
Linux; macOS/Windows untouched.
- Add a packaging gate (verify-linux-glibc-floor.cjs, afterPack): reads
each bundled native binary's objdump -p version needs and fails the
Linux build if any strong GLIBC_/GLIBCXX_/CXXABI_ node exceeds stock
Ubuntu 20.04 (glibc 2.31 / GLIBCXX_3.4.28 / CXXABI_1.3.12). Catches
GLIBC_ABI_DT_RELR, rejects GLIBC_PRIVATE, skips weak needs, fail-closed.
- Docs + tests; the lazy sherpa-onnx speech prebuilt (GLIBCXX_3.4.29,
never loaded at launch) is a documented libstdc++-floor exemption.
* fix(linux): assert DT_NEEDED provider deps in the glibc-floor gate
Harden the packaging gate (flagged in adversarial re-eval): the version-floor
check alone can false-pass if the patch's forced `-l:libutil.so.1` ever silently
drops — the pinned openpty@GLIBC_2.2.5 still resolves from libc's compat alias at
build time, but fails to load on Ubuntu 20.04 where openpty/forkpty live only in
libutil. The gate now also asserts that any binary importing openpty/forkpty
keeps libutil.so.1 in DT_NEEDED. Validated on a real symver-pinned .so with
libutil dropped (now fails) vs. present (passes). Documents the recommended
real-host smoke-test follow-up.
