Revision history for Proc-Spawner (EXPERIMENTAL)

0.02  unreleased (2026-11-02)
      - Documentation: POD for Proc::ShellSubset, Proc::ShellSubset::Small and
        Proc::ShellSubset::Large; doc/large-subset/ (the large parser's
        specification, how its corpus coverage is measured, with the scripts in
        doc/large-subset/tools/, and its history); doc/parsers/ (the base
        parser's grammar and the provenance of its corpus tests); three more
        decision pages in doc/checklists/.
      - t/parsers.t also checks that Proc::ShellSubset::Small parses every test
        string as Proc::ShellSubset does, and, with dash and bash in PATH, that
        both shells accept what only the large grammar accepts; the checks that
        need dash and bash are skipped without them (they used to fail).
      - The message for a construct outside the subset found at run time
        (status 248) now names Proc::ShellSubset::Large, not ShellSubsetLarge.
      - Every module has $VERSION.
      - t/dash.t: each run has its own tmp/ for the battery strings that wrote fixed
        files in /tmp, and ignores the length of process IDs turned into N.
        Test runs at the same time no longer fail each other (probably the
        unexplained failure X20).  The kill -INT $$ strings are marked FLAKY:
        X19 also shows with a subshell.

0.01  unreleased (2026-11-02)
      - First version: Proc::Spawner (posix_spawn with every glibc 2.39 setting, the
        one event loop), Proc::Spawner::Graph (the executable spawn graph),
        Proc::ShellSpawn (runs shell one-liners without fork), and the parsers
        Proc::ShellSubset, Proc::ShellSubset::Small, Proc::ShellSubset::Large.
      - Builds with older glibc (seen failing on 2.36): Makefile.PL probes for each
        posix_spawn extension, and an option the libc lacks follows UNSUPPORTED.
      - No "Hexadecimal number > 0xffffffff" warning from t/spawner.t or $((0x...)).
      - Tests: t/graph.t, t/parsers.t, t/dash.t besides t/spawner.t.
      - Former names: PosixSpawn (now inside Proc::Spawner), ShellSpawn,
        ShellSubset, ShellSubsetSmall, ShellSubsetLarge.
