Get-PinnedGit no longer invokes tar at all (no $inboxTar seam exists since the PortableGit pin), so the C# stub tar.exe and the Invoke-Native override that bound it were never reached: the test compiled a stub for nothing and its docstring described a mechanism the installer does not have. Keep the real-download Get-PinnedGit run under a bzip2-less PATH and the git.exe + bash.exe contract checks; that is what the test proves.

"""Pinned git staging must not need a bzip2-capable tar (#122512, #122774).
|
|
|
|
Stock Windows 10 ships a System32 tar.exe without a bzip2 filter, so the
|
|
old .tar.bz2 pin died at stage=prerequisites ("tar.exe: Error opening
|
|
archive: Can't initialize filter; unable to run program \"bzip2 -d\"").
|
|
Get-PinnedGit now stages the PortableGit self-extractor, which needs
|
|
neither tar nor bzip2. The driver below runs the real Get-PinnedGit
|
|
against the real pinned archive with a PATH that carries no bzip2 (or
|
|
anything else to fall back on) and demands a working git.exe plus the
|
|
bundled bash contract pm/shell.py relies on.
