Moodle versions in git

Source: Moodle Tips

All versions of Moodle are appropriately tagged in the Moodle git repository (git:// so you can use the following to show the commits that relate to each version. Just a note too that major versions are branched using the convention MOODLE_XX_STABLE where XX is the version e.g. MOODLE_36_STABLE for Moodle 3.6.

git show-ref --tags

This gives you something like this:

30e069a061296bef321b31b791a4366a953cae23 refs/tags/v3.6.1
008baea92aa20ee7ff619d37cc6568b076cda00c refs/tags/v3.6.2
ec902921430745139548095e45380ed017acd770 refs/tags/v3.6.3

Here you can see that the v3.6.1 tag has the commit hash 30e069a061296bef321b31b791a4366a953cae23 (the tag is just an alias for that hash).

Use the version.php file to find out the details of that version using the tag as a shortcut e.g.

git show v3.6.1:version.php

Sometimes you want to know what files changed between versions, you can use git diff with the --stat option for that:

git diff v3.6.2 v3.6.3 --stat

If you use a diff/merge tool (e.g. Araxis Merge) you can use the --dir-diff to get a full directory comparison of changes between tags as well. Very handy.

git difftool --dir-diff v3.6.1 v3.6.2

One other useful thing is to look at the log between two tags like so:

git log --oneline v3.6.1..v3.6.2

Handy to see what Moodle fixes were added between tags (MDL-) which you can check against the Moodle Tracker
