On case insensitive systems, when given a user-provided path in the
higher-level index addition functions (eg `git_index_add_bypath` /
`git_index_add_frombuffer`), examine the index to try to match the
given path to an existing directory.
Various mechanisms can cause the on-disk representation of a folder
to not match the representation in HEAD or the index - for example,
a case changing rename of some file `a/file.txt` to `A/file.txt`
will update the paths in the index, but not rename the folder on
disk.
If a user subsequently adds `a/other.txt`, then this should be stored
in the index as `A/other.txt`.
We create a lockfile to update files under GIT_DIR. Sometimes these
files are actually located elsewhere and a symlink takes their place. In
that case we should lock and update the file at its final location
rather than overwrite the symlink.
Some nicer refactoring for index iteration walks.
The index iterator doesn't binary search through the pathlist space,
since it lacks directory entries, and would have to binary search
each index entry and all its parents (eg, when presented with an index
entry of `foo/bar/file.c`, you would have to look in the pathlist for
`foo/bar/file.c`, `foo/bar` and `foo`). Since the index entries and the
pathlist are both nicely sorted, we walk the index entries in lockstep
with the pathlist like we do for other iteration/diff/merge walks.
When using literal pathspecs in diff with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`
turn on the faster iterator pathlist handling.
Updates iterator pathspecs to include directory prefixes (eg, `foo/`)
for compatibility with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`.
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.
When given a pathlist, don't assume that directories sort before
files. Walk through any list of entries sorting before us to make
sure that we've exhausted all entries that *aren't* directories.
Eg, if we're searching for 'foo/bar', and we have a 'foo.c', keep
advancing the pathlist to keep looking for an entry prefixed with
'foo/'.
When parsing user-provided regex patterns for functions, we must not
fail to provide a diff just because a pattern is not well
formed. Ignore it instead.
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.
While we download the remote's remote-tracking branches, we don't
download the tag. This points to the tag auto-follow rules interfering
with the refspec.
When we pass the path of a repository to `_bypath()`, we should behave
like git and stage it as a `_COMMIT` regardless of whether it is
registered a a submodule.
When we have an error renaming the lockfile, we need to make sure
that we remove it upon cleanup. For this, we need to keep track of
whether we opened the file and whether the rename succeeded.
If we did create the lockfile but the rename did not succeed, we
remove the lockfile. This won't protect against all errors, but
the most common ones (target file is open) does get handled.
The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.
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.
When we rename a submodule, we should be merging two sets of information
based on whether their path is the same. We currently only deduplicate
on equal name, which causes us to double-report.
Introduce `git__getenv` which is a UTF-8 aware `getenv` everywhere.
Make `cl_getenv` use this to keep consistent memory handling around
return values (free everywhere, as opposed to only some platforms).
Don't use the filter's free callback to free the actual data structure
holding the filter, as we may not always actually initialize it (the
test may be skipped).
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.
When a refspec contains no rhs and thus won't cause an explicit update,
we skip all the logic, but that means that we don't update FETCH_HEAD
with it, which is what the implicit rhs is.
Add another bit of logic which puts those remote heads in the list of
updates so we put them into FETCH_HEAD.
When we don't own a buffer (asize=0) we currently allow the usage of
grow to copy the memory into a buffer we do own. This muddles the
meaning of grow, and lets us be a bit cavalier with ownership semantics.
Don't allow this any more. Usage of grow should be restricted to buffers
which we know own their own memory. If unsure, we must not attempt to
modify it.
We test the generation of the textual patch via the patch function,
which are just one of two possibilities to get the output.
Add a second patch generation via the diff function to make sure both
outputs are in sync.
