This has the implication that for a given path, we cannot always decide whether it references a directory or a file, and we need to distinguish those cases because ignore rules may treat those differently. E.g. given the following gitignore file: * !/**/ we'd only want to unignore directories, while keeping files ignored. But still, calling `git_ignore_path_is_ignored("dir/")` will say that this directory is ignored because it treats "dir/" as a file path. As said, the `is_ignored` function cannot always decide whether the given path is a file or directory, and thus it may produce wrong results in some cases. While this is unfixable in the general case, we can do better when we are being passed a path name with a trailing path separator (e.g. "dir/") and always treat them as directories.

251d8771	2018-04-06T12:24:10	attr_file: fix handling of directory patterns with trailing spaces When comparing whether a path matches a directory rule, we pass the both the path and directory name to `fnmatch` with `GIT_ATTR_FNMATCH_DIRECTORY` being set. `fnmatch` expects the pattern to contain no trailing directory '/', which is why we try to always strip patterns of trailing slashes. We do not handle that case correctly though when the pattern itself has trailing spaces, causing the match to fail. Fix the issue by stripping trailing spaces and tabs for a rule previous to checking whether the pattern is a directory pattern with a trailing '/'. This replaces the whitespace-stripping in our ignore file parsing code, which was stripping whitespaces too late. Add a test to catch future breakage.

2d9ff8f5	2017-07-10T09:36:19	ignore: honor case insensitivity for negative ignores When computing negative ignores, we throw away any rule which does not undo a previous rule to optimize. But on case insensitive file systems, we need to keep in mind that a negative ignore can also undo a previous rule with different case, which we did not yet honor while determining whether a rule undoes a previous one. So in the following example, we fail to unignore the "/Case" directory: /case !/Case Make both paths checking whether a plain- or wildcard-based rule undo a previous rule aware of case-insensitivity. This fixes the described issue.
b8922fc8	2017-07-07T13:27:27	ignore: keep negative rules containing wildcards Ignore rules allow for reverting a previously ignored rule by prefixing it with an exclamation mark. As such, a negative rule can only override previously ignored files. While computing all ignore patterns, we try to use this fact to optimize away some negative rules which do not override any previous patterns, as they won't change the outcome anyway. In some cases, though, this optimization causes us to get the actual ignores wrong for some files. This may happen whenever the pattern contains a wildcard, as we are unable to reason about whether a pattern overrides a previous pattern in a sane way. This happens for example in the case where a gitignore file contains ".c" and "!src/.c", where we wouldn't un-ignore files inside of the "src/" subdirectory. In this case, the first solution coming to mind may be to just strip the "src/" prefix and simply compare the basenames. While that would work here, it would stop working as soon as the basename pattern itself is different, like for example with "x.c" and "!src/.c. As such, we settle for the easier fix of just not optimizing away rules that contain a wildcard.

Mark when we're handing a star-star so we jump over the elements in our attempt to match the part of the pattern that comes after the star-star. While here, tighten up the check so we don't allow invalid rules through.

1fbeb2f0	2014-09-15T21:59:23	Fix attribute lookup in index for bare repos When using a bare repo with an index, libgit2 attempts to read files from the index. It caches those files based on the path to the file, specifically the path to the directory that contains the file. If there is no working directory, we use `git_path_dirname_r` to get the path to the containing directory. However, for the `.gitattributes` file in the root of the repository, this ends up normalizing the containing path to `"."` instead of the empty string and the lookup the `.gitattributes` data fails. This adds a test of attribute lookups on bare repos and also fixes the problem by simply rewriting `"."` to be `""`.

This cleans up that code to work more robustly even if there is a test failure. This also fixes some valgrind warnings where scanning search paths for separators could end up doing a little bit of sketchy data access when coming to the end of search list.

Unfortunately, the relative path to the .gitignore file was being applied to the global core.excludesfile if that was also named ".gitignore". This fixes that with more precise matching and includes test for ignore rules with leading slashes (which were the primary example of this being broken in the real world). This also backports an improvement to the file context logic from the threadsafe-iterators branch where we don't rely on mutating the key of the attribute file name to generate the context path.

25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
