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.
It can be useful for the caller to know which update commands will be
sent to the server before the packfile is pushed up. git does this via
the pre-push hook.
We don't have hooks, but as it adds introspection into what is
happening, we can add a callback which performs the same function.
The regcomp function returns a non-zero value if compilation of
a regular expression fails. In most places we only check for
negative values, but positive values indicate an error, as well.
Fix this tree-wide, fixing a segmentation fault when calling
git_config_iterator_glob_new with an invalid regexp.
When no reference names could be found we did error out when trying to describe
a commit. This is wrong, though, when the option to fall back to a commit's
object ID is set.
git_checkout_tree() has some fallback behaviors for file systems
which don't have full support of filemodes. Generally works fine,
but if a given file had a change of type from a 0644 to 0755 (i.e.,
you add executable permissions), the fallback behavior incorrectly
triggers when writing hte updated index.
This would cause a git_checkout_tree() command, even with the
GIT_CHECKOUT_FORCE option set, to leave a dirty index on Windows.
Also added checks to an existing test to catch this case.
When there is a tag, we must make sure that we get all referenced
objects from this tag as well. This failing test shows that e.g. when
there is a tagged tree, we insert the top tree but do not descend, thus
causing the clone to have broken links.
Since the Linux platform has a case sensitive file system, the header name should be lower case for cross compiling purposes. (On Linux, the mingw header is called ```windows.h```).
This was but down to 5 when GitHub made a change to their server which
made them stop honouring the include-tag request.
This has recently been corrected, so we can bring it back up to six.
Currently git_submodule_sync writes the submodule's URL to the
key 'branch.<REMOTE_NAME>.remote' while the reference
implementation of `git submodule sync` writes to
'remote.<REMOTE_NAME>.url', which is the intended behavior
according to git-submodule(1).
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.
Clear the error message on git_libgit2_shutdown for all versions of
the library (no threads and Win32 threads). Drop the giterr_clear
in clar, as that shouldn't be necessary.
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.
We want to use the "checkout: moving from ..." message in order to let
git know when a change of branch has happened. Make the convenience
functions for this goal write this message.
This namespace is about behaving like git's branch command, so let's do
exactly that instead of taking a reflog message.
This override is still available via the reference namespace.
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.
When the repository does not contain an index, emulate git's behavior
and upgrade to `SAFE_CREATE`. This allows us to check out repositories
created with `git clone --no-checkout`.
A repository can have multiple "reserved names" now, not just
a single "short name" for the repository folder itself. Refactor
to include a git_repository__reserved_names that returns all the
reserved names for a repository.
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.
Introduce GITTEST_INVASIVE_FS_STRUCTURE for things that are invasive
to your filesystem structure (like creating folders at your filesystem
root) and GITTEST_INVASIVE_FS_SIZE for things that write lots of data.
Always lock the index when we begin the merge, before we write
any of the metdata files. This prevents a race where another
client may run a commit after we have written the MERGE_HEAD but
before we have updated the index, which will produce a merge
commit that is treesame to one parent. The merge will finish and
update the index and the resultant commit would not be a merge at
all.
Introduce `git_indexwriter`, to allow us to lock the index while
performing additional operations, then complete the write (or abort,
unlocking the index).
Correct the merge failed cleanup test. Merge data should not be
cleaned up on conflicts, only on actual failure. And ORIG_HEAD
should not be removed at all.
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.
It fails at least on my computer, though it may depend on some unpredictable
factors (say, will realloc() extend the memory segment in place, or it will
allocate new memory).
`p_stat` calls `git_win32_path_from_utf8`, which canonicalizes the
path. Do not further try to modify the path, else we trim the
trailing slash from a root directory and try to access `C:` instead
of `C:/`.
Test to ensure that we can create a repository at the filesystem
root. Introduces a new test environment variable,
`GITTEST_INVASIVE_FILESYSTEM` for tests that do terrible things like
escaping the clar sandbox and writing to the root directory. It is
expected that the CI builds will enable this but that normal people
would not want this.
The .gitattributes cache should not reload .gitattributes in the
middle of checking out, only between checkout operations. Otherwise,
we'll spend all our time stat'ing and read'ing the gitattributes.
The structinit tests don't make sense unless structure padding
is uniformly initialized, which is unlikely to happen on release
builds. Only enable them for DEBUG builds. Further, rename them
to core::structinit.
On case insensitive filesystems, we may have files in the working
directory that case fold to a name we want to write. Remove those
files (by default) so that we will not end up with a filename that
has the unexpected case.
The documentation for `git_path_join_unrooted` states that the base
length will be returned, so that consumers like checkout know where
to start creating directories instead of always creating directories
at the directory root.
The implementation of the hashsig API disallows computing a signature on
small files containing only a few lines. This new flag disables this
behavior.
git_diff_find_similar() sets this flag by default which means that rename
/ copy detection of small files will now work. This in turn affects the
behavior of the git_status and git_blame APIs which will now detect rename
of small files assuming the right options are passed.
Remove the hook symlink from the test resources, so that we can
have a source tree that is easy to zip up and copy around on systems
that don't support symlinks. Create it dynamically at test execution
instead.
