Older versions of git would only write peeled entries for
items under refs/tags/. Newer versions will write them for
all refs, and we should be prepared to handle that.
When diff encounters an untracked directory, there was a shortcut
that it took which is not compatible with core git. This makes
the default behavior no longer take that shortcut and instead look
inside the untracked directory to see if there are any untracked
files within it. If there are not, then the directory is treated
as an ignore directory instead of an untracked directory. This
has implications for the git_status APIs.
Add a new git_oid_strcmp that compares a string OID with a hex
oid for sort order, and then reimplement git_oid_streq using it.
This actually should speed up git_oid_streq because it only reads
as far into the string as it needs to, whereas previously it would
convert the whole string into an OID and then use git_oid_cmp.
git_oid_ncmp was making some assumptions about the length of
the data - this shifts the check to the top of the loop so it
will work more robustly, limits the max, and adds some tests
to verify the functionality.
This makes diff use the cvar cache for config options where
possible, and also adds support for a number of other config
options to diff including "diff.context", "diff.ignoreSubmodules",
"diff.noprefix", "diff.mnemonicprefix", and "core.abbrev".
To make this natural, this involved a rearrangement of the code
that allocates the diff object vs. the code that initializes it
based on the combination of options passed in by the user and
read from the config.
This commit includes tests for most of these new options as well.
The indexer was creating a packfile object separately from the
code in pack.c which was a problem since I put a call to
git_mutex_init into just pack.c. This commit updates the pack
function for creating a new pack object (i.e. git_packfile_check())
so that it can be used in both places and then makes indexer.c
use the shared initialization routine.
There are also a few minor formatting and warning message fixes.
This adds create and free callback to the git_objects_table so
that more of the creation and destruction of objects can be table
driven instead of using switch statements. This also makes the
semantics of certain object creation functions consistent so that
we can make better use of function pointers. This also fixes a
theoretical error case where an object allocation fails and we
end up storing NULL into the cache.
This adds some basic tests for the oidmap just to make sure that
collisions, etc. are dealt with correctly.
This also adds some tests for the new caching that check if items
are inserted (or not inserted) properly into the cache, and that
the cache can hold up in a multithreaded environment without error.
This moves most of the refdb stuff over to the include/git2/sys
directory, with some minor shifts in function organization.
While I was making the necessary updates, I also removed the
trailing whitespace in a few files that I modified just because I
was there and it was bugging me.
This moves some of the odb_backend stuff that is related to the
internals of an odb_backend implementation into include/git2/sys.
Some of the stuff related to streaming I left in include/git2
because it seemed like it would be reasonably needed by a normal
user who wanted to stream objects into and out of the ODB.
Also, I added APIs for traversing the list of backends so that
some of the tests would not need to access ODB internals.
It used to be separate as an attempt to make the querying easier, but
it didn't work out that way, so put all the data together.
Add git_refspec_string() as well to get the original string, which is
now stored alongside the independent parts.
Introduce git_remote_{fetch,push}_refspecs() to get a list of refspecs
from the remote and rename the refspec-adding functions to a less
silly name.
Use this instead of the vector index hacks in the tests.
A remote can have a multitude of refspecs. Up to now our git_remote's
have supported a single one for each fetch and push out of simplicity
to get something working.
Let the remotes and internal code know about multiple remotes and get
the tests passing with them.
Instead of setting a refspec, the external users can clear all and add
refspecs. This should be enough for most uses, though we're still
missing a querying function.
This adds a new variant iterator that is a raw filesystem iterator
for scanning directories from a root. There is still more work to
do to blend this with the working directory iterator.
