Subject: [PATCH v2] t2400: Fix test failures when using grep 2.5
Date: Sun, 16 Jul 2023 03:38:42 +0000 [thread overview]
Message-ID: <20230716033743.18200-1-jacobabel@nullpo.dev> (raw)
In-Reply-To: <20230715025512.7574-1-jacobabel@nullpo.dev>
Replace all cases of `\s` with `[[:blank:]]` or ` ` as older versions
of GNU grep (and from what it seems most versions of BSD grep) do not
handle `\s`.
For the same reason all cases of `\S` are replaced with `[^ ]`. It's not
an exact replacement (as it does not match tabs) but it is close enough
for this use case.
Replacing `\S` also needs to occur as `\S` is technically PCRE and not
part of ERE even though most modern versions of grep accept it as ERE.
This commit also drops `--sq` from a rev-parse call as it appears to be
a no-op.

This patch is in response to build failures on GGG's Cirrus CI
freebsd_12 build jobs[1] and was prompted by a discussion thread [2].
These failures seem to be caused by the behavior outlined in [3].
Changes from v1:
* Change `[[:space:]]` to ` ` where possible and `[[:blank:]]`
(tabs and spaces) otherwise as it is more accurate than `[[:space:]]` [4].
* Change `[^[:space:]]` to `[^ ]` [4]. Technically `[^[:blank:]]` would be
more accurate but tabs shouldn't be present where this `[^ ]` is used.
* Drop `--sq` from rev-parse [4] (after further discussion [5]).
* Update commit message to match changes.
