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. Signed-off-by: Jacob Abel <jacobabel@xxxxxxxxxx> --- 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. 1. https://github.com/gitgitgadget/git/pull/1550/checks?check_run_id=14949695859 2. https://lore.kernel.org/git/CALnO6CDryTsguLshcQxx97ZxyY42Twu2hC2y1bLOsS-9zbqXMA@xxxxxxxxxxxxxx/ 3. https://stackoverflow.com/questions/4233159/grep-regex-whitespace-behavior 4. https://lore.kernel.org/git/vn5sylull5lqpitsanlyan5fafxj5dhrxgo6k65c462dhqjbno@uwghfyfdixtk/ 5. https://lore.kernel.org/git/bj27nq5aputhd66rkqer37vuc7qogpmn6nqyusladdy4k5it7k@u3yvvivrixsy/ Range-diff against v1: 1: 39f57add45 ! 1: ef4ebd7350 t2400: Fix test failures when using grep 2.5 @@ Metadata ## Commit message ## t2400: Fix test failures when using grep 2.5 - Replace all cases of `\s` with `[[:space:]]` as older versions of GNU - grep (and from what it seems most versions of BSD grep) do not handle - `\s`. + 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 `[^ ]`.
