On proper git commit messages and frequent git pushesMar 28, 2015
Note: this is a rant on how people use git.
Yesterday, I decided to switch from awesome to dwm. I tried to apply one of the available dwm patches, only to notice it doesn't work with the latest version of dwm. So, I decided to have a look at the source and try to troubleshoot it myself. Running git log I was faced with this commit history:
cdec978 - applied Lukas' focus suggestion at startup, thanks (1 year, 7 months ago) ... d83454f - applied Peters two patches, please test hg tip, if nothing breaks this is 5.9 (3 years, 9 months ago) 27b0142 - applied Garys patch in a slightly modified way (3 years, 9 months ago) 867ba36 - applied Nicolas Capit's patch as interim solution until the multiscreen support is reworked in 6.0 (3 years, 9 months ago)
This is just an excerpt, but these commits messages provide no information on what was changed, how it affects the code base or any valuable input of any kind.
In the end, I'll probably use
git bisect to troubleshoot this issue,
but it would be nice and helpful if I could get some extra information
from the commit history.
Update: for the record, the bug was in my config.h after all.
Another common pitfall I see often, is that people don't realise that
git is decentralized. Being decentralized means, you can code on your
git add -
git commit, test everything and once
you're satisfied with the output and are SURE that everything works
as expected, then AND ONLY then, push to the upstream
repo. Otherwise, you end up with multiple commits for something that
could be squashed in a single commit.
On big projects like the Linux kernel or QEMU, you'll often see patches that are sent multiple times before being merged, just to address the above issues. Unfortunately, this doesn't seem to be a big deal for a lot of newer and smaller projects.Tags: rant software
