20250809.0 Sat Aug 9 2025

20250715.0_01 Tue Jul 15 2025
- #172 - Reduce delays in detecting child exit

20231003.0 Mon Oct 2 2023
Windows now matches other platforms in that a child calling exit(N) causes
result() to return N and full_result() to return N << 8. On Windows, before
this change, result() was returning N >> 8, and full_result() was returning N.
Programs having workarounds for this may need to condition those workarounds on
$IPC::Run::VERSION.
- #157 - On Windows, avoid hang under IPCRUNDEBUG.
- Refresh "cpanfile" from Makefile.PL, to allow use on Windows.
- #163 - Normalize shebangs to /usr/bin/perl
- Fix or skip all tests recently seen to fail on Windows.
- Include t/result.t in releases.
- #168 - Make full_result() and result() Windows behavior match non-Windows.
20220807.0 Mon Aug 1 2022
If your applications rely on portability to Windows, see new documentation
sections "argument-passing rules are program-specific" and "batch files". This
release fixes bugs in runs of Windows programs that use standard command line
parsing rules. Runs of non-standard programs may require changes. Notable
non-standard programs include cmd.exe, cscript.exe, and Cygwin programs.
- #140 - skip t/pty.t test on NetBSD too
- Add strict/warnings
- #142 - Follow Windows argument quoting rules
- #146 - allow win32_newlines.t to actually run
- #150 - Make t/pty.t test pass on OpenBSD.
- #148 - Support Win32 commands having nonstandard command line parsing rules
- Support executing Win32 batch files.
- Add IPC::Run::Win32Process, for delivering nonstandard command lines.
- Fix reporting of Win32::Process::Create() errors.
- #156 - On Windows, avoid hang when closing read end of pipe.
- #155 - Ignore known test failure on msys. - t/windows_search_path.t
- Avoid warning with IPCRUNDEBUG, in Windows spawned children.
- Use $^X, not 'perl', in tests.
- Thanks to the New active developer: Noah Misch!
