There has been discussion for a while about making some set of
the `giterr_set` type functions part of the public API for code
that is implementing new backends to libgit2. This makes the
`giterr_set_str()` and `giterr_set_oom()` functions public.
Fixed some minor `git_repository_hashfile` issues:
- Fixed incorrect doc (saying that repo could be NULL)
- Added checking of object type value to acceptable ones
- Added more tests for various parameter permutations
The existing `git_odb_hashfile` does not apply text filtering
rules because it doesn't have a repository context to evaluate
the correct rules to apply. This adds a new hashfile function
that will apply repository-specific filters (based on config,
attributes, and filename) before calculating the hash.
In the process of adding tests for the max file size threshold
(which treats files over a certain size as binary) there seem to
be a number of problems in the new code with detecting binaries.
This should fix those up, as well as add a test for the file
size threshold stuff.
Also, this un-deprecates `GIT_DIFF_LINE_ADD_EOFNL`, since I
finally found a legitimate situation where it would be returned.
This commit adds a max_size value in the public `git_diff_options`
structure so that the user can automatically flag blobs over a
certain size as binary regardless of other properties.
Also, and perhaps more importantly, this moves binary detection
to be as early as possible in the diff traversal inner loop and
makes sure that we stop loading objects as soon as we decide that
they are binary.
The `git_diff_iterator_num_files` API was problematic, since we
don't actually know the exact number of files to be iterated over
until we load those files into memory. This replaces it with a
new `git_diff_iterator_progress` API that goes from 0 to 1, and
moves and renamed the old API for the internal places that can
tolerate a max value instead of an exact value.
This refactors the diff output code so that an iterator object
can be used to traverse and generate the diffs, instead of just
the `foreach()` style with callbacks. The code has been rearranged
so that the two styles can still share most functions.
This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses
that as a common error code for marking the end of iteration when
using a iterator style of object.
This expands the types of peeling that `git_object_peel` knows
how to do to include TAG -> BLOB peeling, and makes the errors
slightly more consistent depending on the situation. It also
adds a new special behavior where peeling to ANY will peel until
the object type changes (e.g. chases TAGs to a non-TAG).
Using this expanded peeling, this replaces peeling code that was
embedded in `git_tag_peel` and `git_reset`.
It's not really needed with the current code as we have EOS and the
sideband's flush to tell us we're done.
Keep the distinction between processed and received objects.
This is a big redesign of the git_submodule_status API and the
implementation of the redesigned API. It also fixes a number of
bugs that I found in other parts of the submodule API while
writing the tests for the status part.
This also fixes a couple of bugs in the iterators that had not
been noticed before - one with iterating when there is a gitlink
(i.e. separate-work-dir) and one where I was treating anything
even vaguely submodule-like as a submodule, more aggressively
than core git does.
This cleans up a number of items suggested during code review
with @vmg, including:
* renaming "outside repo" config API to `git_config_open_default`
* killing the `git_config_open_global` API
* removing the `git_` prefix from the static functions in fileops
* removing some unnecessary functionality from the "cp" command
This extends git_repository_init_ext further with support for
initializing the repository from an external template directory
and with support for the "create shared" type flags that make a
set GID repository directory.
This also adds tests for much of the new functionality to the
existing `repo/init.c` test suite.
Also, this adds a bunch of new utility functions including a
very general purpose `git_futils_mkdir` (with the ability to
make paths and to chmod the paths post-creation) and a file
tree copying function `git_futils_cp_r`. Also, this includes
some new path functions that were useful to keep the code
simple.
