git_repository_free() calls git_odb_free() if the owned odb is not null.
According to the doc, when setting a new odb through git_repository_set_odb() the caller has to take care of releasing the odb by himself.
Adds a new public reference function `git_reference_lookup_oid`
that directly resolved a reference name to an OID without returning
the intermediate `git_reference` object (hence, no free needed).
Internally, this adds a `git_reference_lookup_resolved` function
that combines looking up and resolving a reference. This allows
us to be more efficient with memory reallocation.
The existing `git_reference_lookup` and `git_reference_resolve`
are reimplmented on top of the new utility and a few places in the
code are changed to use one of the two new functions.
This updates to the latest clar which includes the helpers
`cl_assert_equal_s` and `cl_assert_equal_i`. Convert the code
over to use those and remove the old libgit2-only helpers.
git_repository_free() calls git_index_free() if the owned index is not null.
According to the doc, when setting a new index through git_repository_set_index() the caller has still to take care of releasing the index by itself.
In order to cope with this, this fix makes sure the index refcount is incremented when a new repository is being plugged a new index.
This adds preliminary support for pathspecs to diff and status.
The implementation is not very optimized (it still looks at
every single file and evaluated the the pathspec match against
them), but it works.
It's implemented in revwalk.c so it has access to the revision
walker's commit cache and related functions. The algorithm is the one
used by git, modified so it fits better with the library's functions.
The code was already there, so factor it out and let users push an OID
by giving it a reference name. Only refs to commits are
supported. Annotated tags will throw an error.
Add a new command `git_repository_open_ext` with extended options
that control how searching for a repository will be done. The
existing `git_repository_open` and `git_repository_discover` are
reimplemented on top of it. We may want to change the default
behavior of `git_repository_open` but this commit does not do that.
Improve support for "gitdir" files where the work dir is separate
from the repo and support for the "separate-git-dir" config. Also,
add support for opening repos created with `git-new-workdir` script
(although I have only confirmed that they can be opened, not that
all functions work correctly).
There are also a few minor changes that came up:
- Fix `git_path_prettify` to allow in-place prettifying.
- Fix `git_path_root` to support backslashes on Win32. This fix
should help many repo open/discover scenarios - it is the one
function called when opening before prettifying the path.
- Tweak `git_config_get_string` to set the "out" pointer to NULL
if the config value is not found. Allows some other cleanup.
- Fix a couple places that should have been calling
`git_repository_config__weakptr` and were not.
- Fix `cl_git_sandbox_init` clar helper to support bare repos.
When processing status for a newly checked out repo, it is
possible that there will be submodules that have not yet been
initialized. The only way to distinguish these from untracked
directories is to have some knowledge of submodules. This
commit adds a new submodule API which, given a name or path,
can determine if it appears to be a submodule and can give
information about the submodule.
There was an error in the tree iterator where it would
delete two tree levels instead of just one when popping
up a tree level. Unfortunately the test data for the
tree iterator did not have any deep trees with subtrees
in the middle of the tree items, so this problem went
unnoticed. This contains the 1-line fix plus new test
data and tests that reveal the issue.
This gives `git_status_foreach()` back its old behavior of
emulating the "--untracked=all" behavior of git. You can
get any of the various --untracked options by passing flags
to `git_status_foreach_ext()` but the basic version will
keep the behavior it has always had.
This fixes the bug that @nulltoken found (thank you!) where
if there were untracked directories alphabetically after the
last tracked item, the diff implementation would deref a NULL
pointer.
The fix involved the code which decides if it is necessary
to recurse into a directory in the working dir, so it was
easy to add a new option `GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS`
to control if the contents of untracked directories should be
included in status.
This "fixes" the broken t18 status tests to accurately reflect
the new behavior for "created" untracked subdirectories. See
discussion in the PR for more details.
This also contains the submodules unit test that I forgot to
git add, and ports most of the t18-status.c tests to clar (still
missing a couple of the git_status_file() single file tests).
This is a work in progress. This adds two new sets of tests,
the issue_592 tests from @nulltoken's pull request #601 and
some new tests for submodules. The submodule tests still have
issues where the status is not reported correctly. That needs
to be fixed before merge.
This includes a few cleanups that came up while converting
these files.
This commit introduces a could new git error classes, including
the catchall class: GITERR_INVALID which I'm using as the class
for invalid and out of range values which are detected at too low
a level of library to use a higher level classification. For
example, an overflow error in parsing an integer or a bad letter
in parsing an OID string would generate an error in this class.
This converts the map validation function into a macro, tweaks
the GITERR_OS system error automatic appending, and adds a
tentative new error access API and some quick unit tests for
both the old and new error APIs.
This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
the new style of error handling. Also got the unix and win32
versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.
