Sure enough, having manually performed the same steps as this test, `git status` tells us the following: # On branch master # # Initial commit # # Changes to be committed: # (use "git rm --cached <file>..." to unstage) # # new file: force.txt # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # ../.gitignore # child1/ # child2/ i.e. neither child1 nor child2 is ignored.

f554611a	2014-05-06T12:41:26	Improve checks for ignore containment The diff code was using an "ignored_prefix" directory to track if a parent directory was ignored that contained untracked files alongside tracked files. Unfortunately, when negative ignore rules were used for directories inside ignored parents, the wrong rules were applied to untracked files inside the negatively ignored child directories. This commit moves the logic for ignore containment into the workdir iterator (which is a better place for it), so the ignored-ness of a directory is contained in the frame stack during traversal. This allows a child directory to override with a negative ignore and yet still restore the ignored state of the parent when we traverse out of the child. Along with this, there are some problems with "directory only" ignore rules on container directories. Given "a/*" and "!a/b/c/" (where the second rule is a directory rule but the first rule is just a generic prefix rule), then the directory only constraint was having "a/b/c/d/file" match the first rule and not the second. This was fixed by having ignore directory-only rules test a rule against the prefix of a file with LEADINGDIR enabled. Lastly, spot checks for ignores using `git_ignore_path_is_ignored` were tested from the top directory down to the bottom to deal with the containment problem, but this is wrong. We have to test bottom to top so that negative subdirectory rules will be checked before parent ignore rules. This does change the behavior of some existing tests, but it seems only to bring us more in line with core Git, so I think those changes are acceptable.
0f603132	2014-05-01T14:47:33	Improve handling of fake home directory There are a few tests that set up a fake home directory and a fake GLOBAL search path so that we can test things in global ignore or attribute or config files. 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.

This is not the same behavior as core Git. Instead, we strip a trailing '/' off of any patterns that were matching and just take it to imply the FNM_LEADING_DIR behavior.

6a0956e5	2014-04-18T10:32:35	Pop ignore only if whole relative path matches When traversing the directory structure, the iterator pushes and pops ignore files using a vector. Some directories don't have ignore files, so it uses a path comparison to decide when it is right to actually pop the last ignore file. This was only comparing directory suffixes, though, so a subdirectory with the same name as a parent could result in the parent's .gitignore being popped off the list ignores too early. This changes the logic to compare the entire relative path of the ignore file.

a9528b8f	2014-04-14T15:59:48	Fix core.excludesfile named .gitignore Ignore rules with slashes in them are matched using FNM_PATHNAME and use the path to the .gitignore file from the root of the repository along with the path fragment (including slashes) in the ignore file itself. 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.
8f7bc646	2014-04-10T16:33:39	Fix bug popping ignore files during wd iteration There were a couple bugs in popping ignore files during iteration that could result in incorrect decisions be made and thus ignore files below the root either not being loaded correctly or not being popped at the right time. One bug was an off-by-one in comparing the path of the gitignore file with the path being exited during iteration. The second bug was not correctly truncating the path being tracked during traversal if there were no ignores on the list (i.e. when you have no .gitignore at the root, but do have some in contained directories).
