portable_pty 0.0.4

Cross-platform pseudo-terminal (PTY) for Dart. Spawns shell subprocesses on Linux, macOS, and Windows via a Rust native library. On web, connects through WebSocket or WebTransport to a remote PTY server.

Changelog

0.0.4

• Default native shell resolution now uses /system/bin/sh on Android instead of /bin/sh, matching the platform shell layout.
• Android PTY startup now normalizes termios flags on the opened TTY so line discipline, echo, newline handling, and UTF-8 input behave like an interactive shell session.
• Native Android artifacts need to be rebuilt for this change before the next prebuilt release.

0.0.3+2

• Build-hook progress now logs to stdout so successful prebuilt selection does not show up as ERROR: in Flutter builds.
• Non-fatal cache and download fallback paths are now emitted as Warning: messages instead of stderr noise.

0.0.3+1

• Auto-download prebuilt native libraries from GitHub Releases during the build hook — no more manual dart run portable_pty:setup required.
• Build hook resolution order: env var → local .prebuilt/ → auto-download (cached in outputDirectoryShared) → build from source.
• SHA256 hash verification of downloaded artifacts.
• Fixed _findPrebuiltInProjectRoots() to also match directories with pubspec.yaml + pkgs/ (monorepo/workspace roots).
• Updated setup script default tag to v0.0.3.

0.0.3

• Fixed child process exit codes being incorrectly reported as 0 when running under the Dart test runner. The Dart VM's internal waitpid(-1, 0) thread was reaping PTY children before tryWait() could capture their exit status.
• SIGCHLD handler now extracts exit status from the siginfo_t structure (populated by the kernel at signal delivery time), unaffected by concurrent reaping from other threads.
• Added lock-free PID registry (64 slots) with signal chaining and automatic re-installation if overwritten.
• SIGCHLD is blocked during spawn to prevent a race between child exit and PID registration.
• Cached exit code on the PTY handle so repeated tryWait/wait calls return consistent results.
• Pre-emptive waitpid and kill(pid, 0) fallback paths for robustness when the SIGCHLD handler misses a coalesced signal.

0.0.2

• Added dart run portable_pty:setup command to download prebuilt native libraries for downstream consumers.
• Build hook now finds prebuilt libraries at the consuming project's .prebuilt/<platform>/ directory, eliminating the need to modify the pub cache.
• Build hook search order: env var, monorepo .prebuilt/, project .prebuilt/.

0.0.1+1

• Bumped package version to 0.0.1+1.
