`revwalk.h:commit_lookup()` -> `git_revwalk__commit_lookup()`
and make `git_commit_list_parse()` do real error checking that
the item in the list is an actual commit object. Also fixed an
apparent typo in a test name.
Moved it into graph.{c,h} which i created for the new "graph"
functions namespace. Also adjusted the function prototype
to use `size_t` and `const git_oid *`.
There are many scattered functions that look into the contents of
buffers to do various text manipulations (such as escaping or
unescaping data, calculating text stats, guessing if content is
binary, etc). This groups all those functions together into a
new file and converts the code to use that.
This has two enhancements to existing functionality. The old
text stats function is significantly rewritten and the BOM
detection code was extended (although largely we can't deal with
anything other than a UTF8 BOM).
This fixes some missed places where we can apply const-ness to
various public APIs.
There are still some index and tree APIs that cannot take const
pointers because we sort our `git_vectors` lazily and so we can't
reliably bsearch the index and tree content without applying a
`git_vector_sort()` first.
This also fixes some missed places where size_t can be used and
where const can be applied to a couple internal functions.
This makes the diff functions that take callbacks both take
the payload parameter after the callback function pointers and
pass the payload as the last argument to the callback function
instead of the first. This should make them consistent with
other callbacks across the API.
Without this change, any failed assertion in the second (or a later) test
inside a test suite has a chance of double deleting memory, resulting in
a heap corruption. See #1096 for details.
This leaves alone the test cases where we "just" use cl_git_sandbox_init()
and cl_git_sandbox_cleanup(). These methods already take good care to not
double delete a repository.
Fixes#1096
The workdir iterator has always tried to ignore .git files, but
it turns out there were some bugs. This makes it more robust at
ignoring .git files.
This also makes iterators always check ".git" case insensitively
regardless of the properties of the system. This will make libgit2
skip ".GIT" and the like. This is different from core git, but on
systems with case insensitive but case preserving file systems,
allowing ".GIT" to be added is problematic.
A number of diff APIs and the `git_checkout_index` API take a
`git_repository` object an operate on the index. This updates
them to take a `git_index` pointer explicitly and only fall back
on the `git_repository` index if the index input is NULL. This
makes it easier to operate on a temporary index.
The index iterator could previously only be created from a repo
object, but this allows creating an iterator from a `git_index`
object instead (while keeping, though renaming, the old function).
The reset hard tests had hardcoded expected file content and was
not correctly compensating for CRLF filtering when a file needed
to be reverted by the reset hard. This fixes that.
The existing p_lstat implementation on win32 is not quite POSIX
compliant when setting errno to ENOTDIR. This adds an option to
make is be compliant so that code (such as checkout) that cares
to have separate behavior for ENOTDIR can use it portably.
This also contains a couple of other minor cleanups in the
posix_w32.c implementations to avoid unnecessary work.
Returning NULL for the string when we haven't signaled an error
condition is counter-intuitive and causes unnecessary edge
cases. Return an empty string when asking for a string value for a
configuration variable such as '[section] var' to avoid these edge
cases.
If the distinction between no value and an empty value is needed, this
can be retrieved from the entry directly. As a side-effect, this
change stops the int parsing functions from segfaulting on such a
variable.
The `git_reset` API with the HARD option is still slightly
broken, but this test now does exercise the ability of the
command to revert modified files.
This is a major reworking of checkout strategy options. The
checkout code is now sensitive to the contents of the HEAD tree
and the new options allow you to update the working tree so that
it will match the index content only when it previously matched
the contents of the HEAD. This allows you to, for example, to
distinguish between removing files that are in the HEAD but not
in the index, vs just removing all untracked files.
Because of various corner cases that arise, etc., this required
some additional capabilities in rmdir and other utility functions.
This includes the beginnings of an implementation of code to read
a partial tree into the index based on a pathspec, but that is
not enabled because of the possibility of creating conflicting
index entries.
So, @nulltoken created a failing test case for checkout that
proved to be particularly daunting. If checkout is given only
a very limited strategy mask (e.g. just GIT_CHECKOUT_CREATE_MISSING)
then it is possible for typechange/rename modifications to leave it
unable to complete the request. That's okay, but the existing code
did not have enough information not to generate an error (at least
for tree/blob conflicts).
This led me to a significant reorganization of the code to handle
the failing case, but it has three benefits:
1. The test case is handled correctly (I think)
2. The new code should actually be much faster than the old code
since I decided to make checkout aware of diff list internals.
3. The progress value accuracy is hugely increased since I added
a fourth pass which calculates exactly what work needs to be
done before doing anything.
* Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing
combinations of flags
* Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that
are left empty after removal
* Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file,
not a dir (previously an EEXISTS error was ignored, even for
files) and enable this flag for git_futils_mkpath2file call
* Improve accuracy of error messages from git_futils_mkdir
Apparently git_remote_list() includes even remotes for which git_remote_load() would fail. Sorry @nulltoken, false alarm.
This reverts commit f358ec143c.
This fix makes libgit2 capable of parsing annotated tag objects that lack
the optional message/description field.
Previously, libgit2 treated this field as mandatory and raised a tag_error on
such tags. However, the message field is optional.
An example of such a tag is refs/tags/v2.6.16.31-rc1 in Linux:
$ git cat-file tag refs/tags/v2.6.16.31-rc1
object afaa018cefb6af63befef1df7d8febaae904434f
type commit
tag v2.6.16.31-rc1

This improves docs in some of the public header files, cleans
up and improves some of the example code, and fixes a couple
of pedantic warnings in places.
This adds a new API that allows users to reload the config if the
file has changed on disk. A new config callback function to
refresh the config was added.
The modified time and file size are used to test if the file needs
to be reloaded (and are now stored in the disk backend object).
In writing tests, just using mtime was a problem / race, so I
wanted to check file size as well. To support that, I extended
`git_futils_readbuffer_updated` to optionally check file size in
addition to mtime, and I added a new function `git_filebuf_stats`
to fetch the mtime and size for an open filebuf (so that the
config could be easily refreshed after a write).
Lastly, I moved some similar file checking code for attributes
into filebuf. It is still only being used for attrs, but it
seems potentially reusable, so I thought I'd move it over.
This improves the naming for the rename related functionality
moving it to be called `git_diff_find_similar()` and renaming
all the associated constants, etc. to make more sense.
I also moved the new code (plus the existing `git_diff_merge`)
into a new file `diff_tform.c` where I can put new functions
related to manipulating git diff lists.
This also updates the implementation significantly from the
last revision fixing some ordering issues (where break-rewrite
needs to be handled prior to copy and rename detection) and
improving config option handling.
