Hi,
this patch series starts to parse TAP output generated by our tests when
executing them via Meson. This has the benefit that Meson starts to
understand skipped tests and reports how many subtests have been
executed:
```
$ meson test t002*
ninja: Entering directory `/home/pks/Development/git/build'
1/10 t0024-crlf-archive OK 0.17s 2 subtests passed

10/10 t0027-auto-crlf OK 26.35s 2600 subtests passed
Ok: 9
Fail: 0
Skipped: 1
```
This new feature is only enabled with Meson 1.8 and newer, which
contains a bugfix that we have upstreamed [1] to make the TAP parser
work in `meson test --interactive` mode.
Despite the changes to Meson itself, this patch series also contains a
couple of fixes for our test suite that caused us to not generate proper
TAP output.
Changes in v2:
- Add a patch to fix an unexpectedly passing test on macOS.
- A couple more fixes for broken TAP output.
- Link to v1: https://lore.kernel.org/r/20250506-pks-meson-tap-v1-0-5aaab2942a4c@xxxxxx
Changes in v3:
- Split up the patch that silences output into multiple patches and
rework them a bit.
- Remove redirect that was retained by accident from an earlier
version.
- Slight rewording of a commit message.
- Treat unexpected passes as failure in prove(1) and when executing
the test directly.
- Link to v2: https://lore.kernel.org/r/20250527-pks-meson-tap-v2-0-ae360f77786e@xxxxxx
Changes in v4:
- Fix references to git-p4(1), which was mistyped as git-b4(1).
- A couple of commit message improvements.
- Avoid duplicate test names in t4041.
- Link to v3: https://lore.kernel.org/r/20250530-pks-meson-tap-v3-0-676f5e41f2e4@xxxxxx
Thanks!
