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.
