We do not error on "merge conflicts"; on the contrary, merge conflicts
are a normal part of merging. We only error on "checkout conflicts",
where a change exists in the index or the working directory that would
otherwise be overwritten by performing the checkout.
This *may* happen during merge (after the production of the new index
that we're going to checkout) but it could happen during any checkout.
Mark the `old_file` and `new_file` sides of a delta with a new bit,
`GIT_DIFF_FLAG_EXISTS`, that introduces that a particular side of
the delta exists in the diff.
This is useful for indicating whether a working directory item exists
or not, in the presence of a conflict. Diff users may have previously
used DELETED to determine this information.
It's not always obvious the mapping between stage level and
conflict-ness. More importantly, this can lead otherwise sane
people to write constructs like `if (!git_index_entry_stage(entry))`,
which (while technically correct) is unreadable.
Provide a nice method to help avoid such messy thinking.
When diffing against an index, return a new `GIT_DELTA_CONFLICTED`
delta type for items that are conflicted. For a single file path,
only one delta will be produced (despite the fact that there are
multiple entries in the index).
Index iterators now have the (optional) ability to return conflicts
in the index. Prior to this change, they would be omitted, and callers
(like diff) would omit conflicted index entries entirely.
This can be used by tools to show mesages about failing to communicate
with the server. The error message in this case will often contain the
server's error message, as far as it managed to send anything.
When we fail to read from stdout, it's typically because the URL was
wrong and the server process has sent some output over its stderr
output.
Read that output and set the error message to whatever we read from it.
These were left over from the culling as it's not clear which use-cases
might benefit from this. It is not clear that we want to support any
use-case which depends on changing the remote's idea of the base
refspecs rather than passing in different per-operation refspec list, so
remove these functions.
In `git_rebase_operation_current()`, indicate when a rebase has not
started (with `GIT_REBASE_NO_OPERATION`) rather than conflating that
with the first operation being in-progress.
The default behaviour for the packbuilder is to perform the work in a
single thread, which is fine for the public API, but we currently have
no way for a user to determine the number of threads to use when
creating the packfile, which makes our clone behaviour over the
filesystem quite a bit slower than what git offers.
This is a very particular scenario, in which we avoid spawning git by
being ourselves the server-side, so it's probably ok to auto-set the
threading, as the upload-pack process would do if we were talking to
git.
When we rename a reference, we want the old and new ids to be the same
one (as we did not change it). The normal code path looks up the old id
from the current value of the brtanch, but by the time we look it up, it
does not exist anymore and thus we write a zero id.
Pass the old id explicitly instead.
This changes the get_entry() method to return a refcounted version of
the config entry, which you have to free when you're done.
This allows us to avoid freeing the memory in which the entry is stored
on a refresh, which may happen at any time for a live config.
For this reason, get_string() has been forbidden on live configs and a
new function get_string_buf() has been added, which stores the string in
a git_buf which the user then owns.
The functions which parse the string value takea advantage of the
borrowing to parse safely and then release the entry.
The signature for the reflog is not something which changes
dynamically. Almost all uses will be NULL, since we want for the
repository's default identity to be used, making it noise.
In order to allow for changing the identity, we instead provide
git_repository_set_ident() and git_repository_ident() which allow a user
to override the choice of signature.
git_index_add_frombuffer enables now to store a memory buffer in the odb
and to store an entry in the index directly if the index is attached to a
repository.
