When checking out with the GIT_CHECKOUT_REMOVE_UNTRACKED option
and there was an entire tree in the working directory and in the
index that is not in the baseline nor target commit, the tree was
correctly(?) removed from the working directory but was not
successfully removed from the index. This fixes that and adds a
test of the functionality.
For clone to work as expected, it should be using a SAFE_CREATE
checkout (i.e. create files that are missing, even if the target
tree matches the current HEAD).
Test a number of other cases, including intentionally forced
conflicts and deeper inspection that trees get created properly.
There is a still a bug in checkout because the first test here
(i.e. test_checkout_typechange__checkout_typechanges_safe) should
be able to pass with GIT_CHECKOUT_SAFE as a strategy, but it will
not because of some lingering submodule checkout issues.
Stash was sometimes obscuring the actual error code, replacing it
with a -1 when there was more descriptive value. This updates
stash to preserve the original error code more reliably along
with a variety of other error handling tweaks.
I believe this is an improvement, but arguably, preserving the
underlying error code may result in values that are harder to
interpret by the caller who does not understand the internals.
Discussion is welcome!
Previously a NULL oid was handled like an empty buffer and
returned a status empty string. This makes git_oid_tostr()
set the output buffer to the empty string instead.
Make checkout update entries in the index for all files that are
updated and/or removed, unless flag GIT_CHECKOUT_DONT_UPDATE_INDEX
is given. To do this, iterators were extended to allow a little
more introspection into the index being iterated over, etc.
This flips checkout back to be driven off the changes between
the baseline and the target trees. This reinstates the complex
code for tracking the contents of the working directory, but
overall, I think the resulting logic is easier to follow.
I've tried to map out the detailed behaviors of checkout and make
sure that we're handling the various cases correctly, along with
providing options to allow us to emulate "git checkout" and "git
checkout-index" with the various flags. I've thrown away flags
in the checkout API that seemed like clutter and added some new
ones. Also, I've converted the conflict callback to a general
notification callback so we can emulate "git checkout" output and
display "dirty" files.
As of this commit, the new behavior is not working 100% but some
of that is probably baked into tests that are not testing the
right thing. This is a decent snapshot point, I think, along the
way to getting the update done.
This adds a failure reporting function that is called by
cl_git_pass which captures the actual error return code and
the error message if available in the failure report.
* gen_pktline() in smart_protocol.c was skipping refspecs that deleted
refs that were not advertised by the server. The new behavior is to
send a delete command with an old-id of zero, which matches the behavior
of the official git client.
* Update test_network_push__delete() in reaction to above fix.
* Obviate messy logic that handles missing push_spec rrefs by canonicalizing
push_spec. After calculate_work(), loid, roid, and rref, are filled in with
exactly what is sent to the server
