Hi Erik,
The build system shows you the commit message recorded in the super-repository
for each change, including the commits in the submodules. If everything is
working well, this is usually enough to tell what is wrong. If you want to be
more certain, and not rely on the commit messages in the super-repo or
submodules being accurate, you can check the exact differences as follows.
First check out the git super-repository containing the Einstein Toolkit:
git clone --recursive
https://bitbucket.org/einsteintoolkit/einsteintoolkit.git
Next identify the two commits that you want to compare. You can get these from
Jenkins by clicking on the build and reading what it says next to "Revision".
In this case, the commits are 63280a1829c497e99fc45e6e5e3c929b605a52ca and
cf35c92b2c588220e3902817e43a76d33bcd412e.
You can get the changes in the super-repository with
git diff
63280a1829c497e99fc45e6e5e3c929b605a52ca..cf35c92b2c588220e3902817e43a76d33bcd412e
This does not recurse into the submodules and show their diffs, it just reports
the change to the version of the submodule. It would be nice if there was a
built-in way to do this easily in Git, but there isn't. Instead, you can use
this
while read a submodule range; do (echo "Submodule $submodule"; cd
$submodule; git diff ${range%*:}); done < <(git diff --submodule
63280a1829c497e99fc45e6e5e3c929b605a52ca..cf35c92b2c588220e3902817e43a76d33bcd412e|grep
'^Submodule')
This will give you the complete diffs of all submodule changes between the two
super-repository commits.
