So far they only create a repo, setup the "origin"
remote, and fetch. The API probably needs work as
well; there's no way to get progress information
at this point.
Also uncovered a shortcoming; git_remote_download
doesn't fetch over local transport.
The second call to assert_config_entry_on_init_bytype is cleaned up by
the main cleanup function, but that overwrites the first _repo. Make
sure that one doesn't leak.
This fixes git_index_add and git_index_append to behave more like
core git, preserving old filemode data in the index when adding
and/or appending with core.filemode = false.
This also has placeholder support for core.symlinks and
core.ignorecase, but those flags are not implemented (well,
symlinks has partial support for preserving mode information in
the same way that git does, but it isn't tested).
git_commit() and git_tag() no longer prettify the
message by default. This has to be taken care of
by the caller.
This has the nice side effect of putting the
caller in position to actually choose to strip
the comments or not.
There are three actual changes in this commit:
1. When the trailing newline of a file is removed in a diff, the
change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed
to the callback. Previously, the `ADD_EOFNL` constant was given
which was just an error in my understanding of when the various
circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and
should never be generated. A new newline is simply an `ADD`.
2. Rewrote the `diff_delta__merge_like_cgit` function that contains
the core logic of the `git_diff_merge` implementation. The new
version doesn't actually have significantly different behavior,
but the logic should be much more obvious, I think.
3. Fixed a bug in `git_diff_merge` where it freed a string pool
while some of the string data was still in use. This led to
`git_diff_print_patch` accessing memory that had been freed.
The rest of this commit contains improved documentation in `diff.h`
to make the behavior and the equivalencies with core git clearer,
and a bunch of new tests to cover the various cases, oh and a minor
simplification of `examples/diff.c`.
File modes were both not being ignored properly on platforms
where they should be ignored, nor be diffed consistently on
platforms where they are supported.
This change adds a number of diff and status filemode change
tests. This also makes sure that filemode-only changes are
included in the diff output when they occur and that filemode
changes are ignored successfully when core.filemode is false.
There is no code that automatically toggles core.filemode
based on the capabilities of the current platform, so the user
still needs to be careful in their .git/config file.
- Do not create new levels of fanout when creating notes from libgit2
- Insert a note in an existing matching fanout
- Remove a note from an existing fanout
- Cleanup git_note_read, git_note_remove, git_note_foreach, git_note_create methods in order use tree structures instead of tree_oids
git_status_file would always return GIT_ENOTFOUND for these files.
The underlying bug was that git__strcmp_cb, which is used by
git_path_with_stat_cmp to sort entries in the working directory,
compares strings based on unsigned chars (this is confirmed by the
strcmp(3) manpage), while git__prefixcmp, which is used by
workdir_iterator__entry_cmp to search for a path in the working
directory, compares strings based on char. So the sort puts this path at
the end of the list, while the search expects it to be at the beginning.
The fix was simply to make git__prefixcmp compare using unsigned chars,
just like strcmp(3). The rest of the change is just adding/updating
tests.
This test is intended to verify that 64-bit
machines can handle parsing dates in 2039 and
beyond, and fails on 32-bit machines. It is now
omitted when run on a 32-bit machine to eliminate
an expected failure.
The error codes from failed lookups of system and global files
on Windows were not consistent with the codes returned on other
platforms. This makes the error detection patterns match and
adds a unit test for the various errors.
This fixes two bugs:
* Issue #728 where git_status_file was not working for files
that contain spaces. This was caused by reusing the "fnmatch"
parsing code from ignore and attribute files to interpret the
"pathspec" that constrained the files to apply the status to.
In that code, unescaped whitespace was considered terminal to
the pattern, so a file with internal whitespace was excluded
from the matched files. The fix was to add a mode to that code
that allows spaces and tabs inside patterns. This mode only
comes into play when parsing in-memory strings.
* The other issue was undetected, but it was in the recently
added code to reload gitattributes / gitignores when they were
changed on disk. That code was not clearing out the old values
from the cached file content before reparsing which meant that
newly added patterns would be read in, but deleted patterns
would not be removed. The fix was to clear the vector of
patterns in a cached file before reparsing the file.
The function to convert UTF-16 to UTF-8 was only allocating a
buffer of wcslen(utf16str) bytes for the UTF-8 string, but that
is not sufficient if you have multibyte characters, and so when
those occured, the conversion was failing. This updates the
conversion functions to use the Win APIs to calculate the correct
buffer lengths.
Also fixes a comparison in the unit tests that would fail if
you did not have a particular environment variable set.
On Windows, we are having problems with home directories
that have non-ascii characters in them. This rewrites the
relevant code to fetch environment variables as UTF-16 and
then explicitly map then into UTF-8 for our internal usage.
Creating a workdir iterator on a directory with absolutely
no files was returning an error (GIT_ENOTFOUND) instead of
an iterator for nothing. This fixes that and includes two
new tests that cover that case.
There was a bug where tracked files inside directories that were
inside ignored directories where not being found by status. To
make that a little clearer, if you have a .gitignore with:
ignore/
And then have the following files:
ignore/dir/tracked <-- actually a tracked file
ignore/dir/untracked <-- should be ignored
Then we would show the tracked file as being removed (because
when we got the to contained item "dir/" inside the ignored
directory, we decided it was safe to skip -- bzzt, wrong!).
This update is much more careful about checking that we are
not skipping over any prefix of a tracked item, regardless of
whether it is ignored or not.
As documented in diff.c, this commit does create behavior that
still differs from core git with regards to the handling of
untracked files contained inside ignored directories. With
libgit2, those files will just not show up in status or diff.
With core git, those files don't show up in status or diff
either *unless* they are explicitly ignored by a .gitignore
pattern in which case they show up as ignored files.
Needless to say, this is a local behavior difference only, so
it should not be important and (to me) the libgit2 behavior
seems more consistent.
The goal of this work is to rewrite git_status_file to use the
same underlying code as git_status_foreach.
This is done in 3 phases:
1. Extend iterators to allow ranged iteration with start and
end prefixes for the range of file names to be covered.
2. Improve diff so that when there is a pathspec and there is
a common non-wildcard prefix of the pathspec, it will use
ranged iterators to minimize excess iteration.
3. Rewrite git_status_file to call git_status_foreach_ext
with a pathspec that covers just the one file being checked.
Since ranged iterators underlie the status & diff implementation,
this is actually fairly efficient. The workdir iterator does
end up loading the contents of all the directories down to the
single file, which should ideally be avoided, but it is pretty
good.
Since we now rely on it (at least under Solaris), I figured we probably
want to make sure it's accurate. The new test makes sure that creating a
file with a name of length FILENAME_MAX+1 fails.
This fix complements cb0ce16bbe and cover the following additional use cases
- retrieving an object which has been previously searched, found and cached
- retrieving an object through an non ambiguous abbreviated id
This makes the git attributes and git ignores cache check
stat information before using the file contents from the
cache. For cached files from the index, it checks the SHA
of the file instead. This should reduce the need to ever
call `git_attr_cache_flush()` in most situations.
This commit also fixes the `git_status_should_ignore` API
to use the libgit2 standard parameter ordering.
exp() is already defined in math.h. This leads to LMSVC complaining
..\..\libgit2\tests-clar\diff\blob.c(5): error C2365: 'exp' : redefinition; previous definition was 'function'
Renaming the variable fixes this issue.
When a repo is first created, there is no HEAD yet and attempting
to diff files in the index was showing nothing because a tree
iterator could not be constructed. This adds an "empty" iterator
and falls back on that when the head cannot be looked up.
This has the nice side effect of making test_attr_repo__staging_properly_normalizes_line_endings_according_to_gitattributes_directives() test pass again on Windows. This test started to fail after commit 674a198 was applied.
'git commit' and 'git tag -a' enforce some conventions, like cleaning up excess whitespace and making sure that the last line ends with a '\n'. This fix replicates this behavior.

MINGW32 does not define _mktemp_s, so we can just use _mktemp instead. See
the non-compressed/non-base64-encoded version of the patch here:
http://gist.github.com/2605249
Depending on the operation, we need to consider gitattributes
in both the work dir and the index. This adds a parameter to
all of the gitattributes related functions that allows user
control of attribute reading behavior (i.e. prefer workdir,
prefer index, only use index).
This fix also covers allowing us to check attributes (and
hence do diff and status) on bare repositories.
This was a somewhat larger change that I hoped because it had
to change the cache key used for gitattributes files.
