Hello,
I'm sending it here to devel list because after asking around at IRC and
also to friends we ended up with no reasonable explanation about what
happened, and it lead me to consider maybe it could be a bug (!?!?)
I'm running git 2.26.2 on macOS Catalina.
We first noted a package built from pfSense FreeBSD-ports repository [1]
was missing a patch and then after investigate we found these relevant
information (it's all about RELENG_2_4_5 branch):
1. The original commit made in Jan 3 is present in the repo:
❯ git log RELENG_2_4_5 | grep -A5 53e5b36834f1
commit 53e5b36834f1
Author: jim-p <jimp@xxxxxxxxxxx>
Date: Fri Jan 3 11:50:09 2020 -0500
Allow sshguard to process via stdin again. Issue #9971
2. Despite the fact commit was present, the change it introduced was not
present on repository contents.
3. This commit changed the file
security/sshguard/files/patch-src_sshguard.in as we can see:
❯ git show 53e5b36834f1 -- security/sshguard/files/patch-src_sshguard.in
commit 53e5b36834f1
Author: jim-p <jimp@xxxxxxxxxxx>
Date: Fri Jan 3 11:50:09 2020 -0500
Allow sshguard to process via stdin again. Issue #9971

4. Here the odd facts start, git log doesn't show this commit when
filtering the file it changed, which btw, was never moved/renamed.
❯ git log RELENG_2_4_5 -- security/sshguard/files/patch-src_sshguard.in
commit 88d6f4488ab5
Author: delphij <delphij@xxxxxxxxxxx>
Date: Sun Nov 10 18:34:54 2019 +0000
Remove redundant pidfile check.
This fixes an issue that SSHguard won't start after an incompelete
shutdown.
PR: ports/241751
Approved by: portmgr (bugfix blanket)

5. After trying to understand what happened, --follow parameter was used
and it shows that commit. As I mentioned previously, the change it did
on that file was not there, and no other commit reverting it show up.
❯ git log RELENG_2_4_5 --follow -M --
