As refdb and odb backends can be allocated by client code, libgit2
can’t know whether an alternative memory allocator was used, and thus
should not try to call `git__free` on those objects.
Instead, odb and refdb backend implementations must always provide
their own `free` functions to ensure memory gets freed correctly.
When we do not trust the on-disk mode, we use the mode of an existing
index entry. This allows us to preserve executable bits on platforms
that do not honor them on the filesystem.
If there is no stage 0 index entry, also look at conflicts to attempt
to answer this question: prefer the data from the 'ours' side, then
the 'theirs' side before falling back to the common ancestor.
Document that `GIT_DIFF_PATHSPEC_DISABLE` is not necessarily about
explicit path matching, but also includes matching of directory
names. Enforce this in a test.
libgit2 implementations of smart subtransports can simply reach through
the structure, but external implementors cannot.
Add these two functions as a way for the smart subtransports to get the
callbacks as set by the user.
This lock/unlock pair allows for the cller to lock a configuration file
to avoid concurrent operations.
It also allows for a transactional approach to updating a configuration
file. If multiple updates must be made atomically, they can be done
while the config is locked.
When a configuration file is locked, any updates made to it will be done
to the in-memory copy of the file. This allows for multiple updates to
happen while we hold the lock, preventing races during complex
config-file manipulation.
git_fetch_options was missing from the API docs because it lacked a
documentation comment above the struct declaration.
I used the git_checkout_options docstring as a template.
Also fixes a typo in git_remote_prune_refs (remote, not reamote).
Removing a reflog upon ref deletion is something which only some
backends might wish to do. Backends which are database-backed may wish
to archive a reflog, log-based ones may not need to do anything.
The function was removed, but its declaration and changelog entry about
its removal were forgotten.
The comment in the test doesn't make any sense as the function doesn't
exist anymore, so get rid of it as well.
Allow custom filters with wildcard attributes, so that clients
can support some random `filter=foo` in a .gitattributes and look
up the corresponding smudge/clean commands in the configuration file.
We currently recommend using `git_buf_grow` in order to make a buffer
make an owned copy of the memory it points to. This is not behaviour we
should encourage, so remove this recommendation.
The function itself is not changed, as we need to remain compatible, but
it will be changed not to allow usage on borrowed buffers.
