Module `ThunkIoDisk.MakeRacyTestSpawner`Source

RacyTestSpawner is a functional pure-OCaml spawner that changes directories in a racy, thread-unsafe way.

You'll likely prefer to make a pure-OCaml spawner that is race-free where you'll need to shell out to "/bin/sh" or "cmd.exe" and put a "cd <directory>" in the script. Or use a library like Janestreet's spawn.

spawn ?stdout ?stderr ~unix_cmdline ~windows_appname ~windows_cmdline ~envmods ~dir () spawns a process with environment modifications envmods in the directory dir.

The unix_cmdline is the Unix/native process launch representation: (command, args) where command is the executable path and args is the argv tail used by Unix spawning.

The windows_appname is the exact Windows application name passed directly to CreateProcessW as lpApplicationName. The caller will use MlFront_Core.Platform.Windows.cmd_quote_word to quote it correctly; they must not use Filename.quote since that varies based on the current execution platform.

The windows_cmdline is the exact Windows command line passed directly to CreateProcessW as lpCommandLine. The caller will use MlFront_Core.Platform.Windows.cmd_quote_cmdline to quote it correctly; they must not use Filename.quote_command since that varies based on the current execution platform.

The runtime spawner must not apply any extra quoting or rewriting to either windows_appname or windows_cmdline.

The standard output/error files stdout and stderr are used if specified.
