This changes the git_remote_download() API, but the existing one is
silly, so you don't get to complain.
The new API allows to know how much data has been downloaded, how many
objects we expect in total and how many we've processed.
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.
The code used to assume that there had to be data after the newline in
a tree cache extension entry. This isn't true for a childless
invalidated entry if it's the last one, as there won't be any children
nor a hash to take up space.
Adapt the off-by-one comparison to also work in this case. Fixes#633.
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.
This will allow us to index a packfile as soon as we receive it from
the network as well as storing it with its final name so we don't need
to pass temporary file names around.
As parents are older than their children, we're appending to the
commit list most of the time, which makes an ordered linked list quite
inefficient.
While we're there, don't sort the results list in the main loop, as
we're sorting them afterwards and it creates extra work.
There is no need walk down the parents of a merge base to mark them as
uninteresting because we'll never see them. Calculate the merge bases
in prepare_walk() so mark_uninteresting() can stop at a merge base
instead of walking all the way to the root.
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.
