a7b4b639	2019-08-24T12:14:31	ignore: correct handling of nested rules overriding wild card unignore problem: filesystem_iterator loads .gitignore files in top-down order. subsequently, ignore module evaluates them in the order they are loaded. this creates a problem if we have unignored a rule (using a wild card) in a sub dir and ignored it again in a level further below (see the test included in this patch). solution: process ignores in reverse order. closes #4963
e54343a4	2019-06-29T09:17:32	fileops: rename to "futils.h" to match function signatures Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.
6f6340af	2019-07-18T11:57:55	ignore: fix determining whether a shorter pattern negates another When computing whether we need to store a negative pattern, we iterate through all previously known patterns and check whether the negative pattern undoes any of the previous ones. In doing so we call `wildmatch` and check it's return for any negative error values. If there was a negative return, we will abort and bubble up that error to the caller. In fact, this check for negative values stems from the time where we still used `fnmatch` instead of `wildmatch`. For `fnmatch`, negative values indicate a "real" error, while for `wildmatch` a negative value may be returned if the matching was prematurely aborted. A premature abort may for example also happen if the pattern matches a prefix of the haystack if the pattern is shorter. Returning an error in that case is the wrong thing to do. Fix the code to compare for equality with `WM_MATCH`, only. Negative values returned by `wildmatch` are perfectly fine and thus should be ignored. Add a test that verifies we do not see the error.
05f9986a	2019-06-14T08:06:05	attr_file: convert to use `wildmatch` Upstream git has converted to use `wildmatch` instead of `fnmatch`. Convert our gitattributes logic to use `wildmatch` as the last user of `fnmatch`. Please, don't expect I know what I'm doing here: the fnmatch parser is one of the most fun things to play around with as it has a shtload of weird cases. In all honesty, I'm simply relying on our tests that are by now rather comprehensive in that area. The conversion actually fixes compatibility with how git.git parser "" patterns when the given path does not contain any directory separators. Previously, a pattern "*.foo" erroneously wouldn't match a file "x.foo", while git.git would match. Remove the new-unused LEADINGDIR/NOLEADINGDIR flags for `git_attr_fnmatch`.
b3b6a39d	2019-06-07T11:12:54	attr_file: account for escaped escapes when searching trailing space When determining the trailing space length, we need to honor whether spaces are escaped or not. Currently, we do not check whether the escape itself is escaped, though, which might generate an off-by-one in that case as we will simply treat the space as escaped. Fix this by checking whether the backslashes preceding the space are themselves escaped.
10ac298c	2019-06-07T11:12:42	attr_file: fix unescaping of escapes required for fnmatch When parsing attribute patterns, we will eventually unescape the parsed pattern. This is required because we require custom escapes for whitespace characters, as normally they are used to terminate the current pattern. Thing is, we don't only unescape those whitespace characters, but in fact all escaped sequences. So for example if the pattern was "\", we unescape that to "". As this is directly passed to fnmatch(3) later, fnmatch would treat it as a simple glob matching all files where it should instead only match a file with name "*". Fix the issue by unescaping spaces, only. Add a bunch of tests to exercise escape parsing.
01dda5ff	2019-06-07T08:29:32	tests: unify ignore tests into their own dir We had several occasions where tests for the gitignore had been added to status::ignore instead of the easier-to-handle attr::ignore test suite. This most likely resulted from the fact that the attr::ignore test suite is not easy to discover inside of the attr folder. Furthermore, ignore being part of the attributes code is an implementation detail, only, and thus shouldn't be stressed as much. Improve this by moving both attr::ignore and status::ignore tests into a new ignore test suite.
