add submodule tests
This patch adds 17 tests which check behaviour related to submodules.
The commit problem reported by semarie@ is covered, as well as many
other cases I could think of.
To cover merges I have chosen to write tests for 'got cherrypick'.
Cherrypick runs the same merge code as histedit and rebase. Therefore,
the latter two commands do not need any submodule tests of their own.
Since submodule tree entries are never added to the file index, use cases
which operate on the file index only, or which don't use tree objects,
will not need any tests. This includes cases like marking files for removal
with 'got rm' or staging changes for commit.
All tests simply verify the existing behaviour.
This already provides some insights:
Several commands will try to look up the ID contained in the submodule
tree entry, which will usually fail, unless the (SHA1-wise) same object
happens to exist in both the outer repository and the submodule.
E.g. 'got cat' will show the commit pointed to by a submodule, provided
that a commit with the same ID exists in the local repository. Otherwise
'got cat' will raise an error.
Updating to, and merging, commits which contain changes to submodule tree
entries is already working. Even in cases where a submodule would clash with
a file. Submodule tree entries are simply ignored. If the only path changed in
a commit is a submodule tree entry this results in no-op updates and merges.
And such commits show up with an empty path list in 'got log -P'.
An attempt to commit a file where a submodule exists will fail, and Got will
ask the user to update and try again. But the next commit attempt will fail
in the same way :)
I think this set of tests shows that there is a lot of room for improvement
in behaviour, especially regarding the reporting of error conditions.
With tests it will be much easier for us to see the impact of any changes
we might want to make going forward. We can discuss such changes on a
case-by-case basis, and always adjust test expectations as needed.
Ok? Can anyone think of important test cases I have missed?
