The git_buf_text_gather_stats call returns a boolean indicating if
the file looks like binary data. That shouldn't be an error; it
should be used to skip CRLF processing though.
Fixed the filter order to match core Git, too.
This test demonstrates an interesting behavior of core Git (which
is totally reasonable and which libgit2 matches, although mostly
by coincidence). If you use the ident filter and commit a file
with a garbage ident in it, like '$Id: this is just garbage$' and
then immediately do a 'git checkout-index' with the new file, Git
will not consider the file out of date and will not overwrite the
file with an updated $Id$. Libgit2 has the same behavior. If you
remove the file and then do a checkout-index, it will be replaced
with a filtered version that has injected the OID correctly.
There were a lot of places in the test code base that were creating
a commit from the index on the current branch. This just adds a
helper to handle that case pretty easily. There was only one test
where this change ended up tweaking the test data, so pretty easy
and mostly just a cleanup.
These are a couple of new clar helpers for testing that a file
has expected contents that I extracted from the checkout code.
Actually wrote this as part of an abandoned earlier attempt at a
new filters API, but it will be useful now for some of the tests
I'm going to write.
This is just a bunch of small fixes that I noticed while looking
at the UTF8 and UTF16 path stuff. It fixes a slowdown in looking
for an empty directory (not exiting loop asap), makes the dir name
in the git__DIR structure be a GIT_FLEX_ARRAY to save an allocation,
and fixes some slightly odd assumptions in the cl_getenv helper.
The git_status_file API was doing a hack to deal with files that
are inside ignored directories. The status scan was not reporting
any file in this case, so git_status_file would attempt a final
"stat()" call, and return IGNORED if the file actually existed.
On case-insensitive filesystems where core.ignorecase is set
incorrectly, this magic check can "succeed" and report a file
as ignored when it should actually return ENOTFOUND.
Now that we have the GIT_STATUS_OPT_RECURSE_IGNORED_DIRS, we can
use that flag to make sure that git_status_file() will look into
ignored directories and eliminate the hack completely, so we give
the correct error.
This adds a helper function for the cases where you want to
quickly set a single boolean config value for a repository.
This allowed me to remove a lot of code.
This switches the APIs for setting and getting the global/system
search paths from using git_strarray to using a simple string with
GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment
PATH variable would contain. This makes it simpler to get and set
the value.
I also added code to expand "$PATH" when setting a new value to
embed the old value of the path. This means that I no longer
require separate actions to PREPEND to the value.
The cppcheck static analyzer generates warnings for a bunch of
places in the libgit2 code base. All the ones fixed in this
commit are actually false positives, but I've reorganized the
code to hopefully make it easier for static analysis tools to
correctly understand the structure. I wouldn't do this if I
felt like it was making the code harder to read or worse for
humans, but in this case, these fixes don't seem too bad and will
hopefully make it easier for better analysis tools to get at any
real issues.
This adds a failure reporting function that is called by
cl_git_pass which captures the actual error return code and
the error message if available in the failure report.
