Patrick Steinhardt 20b4c175 2018-06-05T16:12:58 ignore: fix negative leading directory rules unignoring subdirectory files When computing whether a file is ignored, we simply search for the first matching rule and return whether it is a positive ignore rule (the file is really ignored) or whether it is a negative ignore rule (the file is being unignored). Each rule has a set of flags which are being passed to `fnmatch`, depending on what kind of rule it is. E.g. in case it is a negative ignore we add a flag `GIT_ATTR_FNMATCH_NEGATIVE`, in case it contains a glob we set the `GIT_ATTR_FNMATCH_HASGLOB` flag. One of these flags is the `GIT_ATTR_FNMATCH_LEADINGDIR` flag, which is always set in case the pattern has a trailing "/*" or in case the pattern is negative. The flag causes the `fnmatch` function to return a match in case a string is a leading directory of another, e.g. "dir/" matches "dir/foo/bar.c". In case of negative patterns, this is wrong in certain cases. Take the following simple example of a gitignore: dir/ !dir/ The `LEADINGDIR` flag causes "!dir/" to match "dir/foo/bar.c", and we correctly unignore the directory. But take this example: *.test !dir/* We expect everything in "dir/" to be unignored, but e.g. a file in a subdirectory of dir should be ignored, as the "*" does not cross directory hierarchies. With `LEADINGDIR`, though, we would just see that "dir/" matches and return that the file is unignored, even if it is contained in a subdirectory. Instead, we want to ignore leading directories here and check "*.test". Afterwards, we have to iterate up to the parent directory and do the same checks. To fix the issue, disallow matching against leading directories in gitignore files. This can be trivially done by just adding the `GIT_ATTR_FNMATCH_NOLEADINGDIR` to the spec passed to `git_attr_fnmatch__parse`. Due to a bug in that function, though, this flag is being ignored for negative patterns, which is fixed in this commit, as well. As a last fix, we need to ignore rules that are supposed to match a directory when our path itself is a file. All together, these changes fix the described error case.
Patrick Steinhardt 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.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Patrick Steinhardt 2480d0eb 2017-06-30T13:34:05 Add missing license headers Some implementation files were missing the license headers. This commit adds them.

Edward Thomson 90997e40 2015-05-12T12:14:55 attr: less path mangling during attribute matching When handling attr matching, simply compare the directory path where the attribute file resides to the path being matched. Skip over commonality to allow us to compare the contents of the attribute file to the remainder of the path. This allows us to more easily compare the pattern directly to the path, instead of trying to guess whether we want to compare the path's basename or the full path based on whether the match was inside a containing directory or not. This also allows us to do fewer translations on the pattern (trying to re-prefix it.)
Edward Thomson 9465bedb 2015-05-12T16:02:18 attr: don't mangle file path during attr matching When determining whether some file matches an attr pattern, do not try to truncate the path to pass to fnmatch. When there is no containing directory for an item (eg, from a .gitignore in the root) this will cause us to truncate our path, which means that we cannot do meaningful comparisons on it and we may have false positives when trying to determine whether a given file is actually a file or a folder (as we have lost the path's base information.) This mangling was to allow fnmatch to compare a directory on disk to the name of a directory, but it is unnecessary as our fnmatch accepts FNM_LEADING_DIR.
Edward Thomson ef6d0722 2015-05-12T13:06:05 attr: don't match files for folders When ignoring a path "foo/", ensure that this is actually a directory, and not simply a file named "foo".

Edward Thomson d4b1b767 2015-02-03T00:03:49 checkout: cache system attributes file location
Edward Thomson 9f779aac 2015-01-29T14:40:55 attrcache: don't re-read attrs during checkout During checkout, assume that the .gitattributes files aren't modified during the checkout. Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.
Jacques Germishuys 6f73e026 2014-12-24T11:42:50 Plug some leaks
Vicent Marti 72d00241 2014-11-21T13:32:21 attr_file: Do not assume ODB data is NULL-terminated That's a bad assumption to make, even though right now it holds (because of the way we've implemented decompression of packfiles), this may change in the future, given that ODB objects can be binary data. Furthermore, the ODB object can return a NULL pointer if the object is empty. Copying the NULL pointer to the strbuf lets us handle it like an empty string. Again, the NULL pointer is valid behavior because you're supposed to check the *size* of the object before working on it.
Carlos Martín Nieto 6069042f 2014-11-05T16:51:39 ignore: don't leak rules into higher directories A rule "src" in src/.gitignore must only match subdirectories of src/. The current code does not include this context in the match rule and would thus consider this rule to match the top-level src/ directory instead of the intended src/src/. Keep track fo the context in which the rule was defined so we can perform a prefix match.
Carlos Martín Nieto 5c54e216 2014-11-05T16:07:07 ignore: consider files with a CR in their names We currently consider CR to start the end of the line, but that means that we miss cases with CR CR LF which can be used with git to match files whose names have CR at the end of their names. The fix from the patch comes from Russell's comment in the issue. This fixes #2536.
Russell Belfer a0cacc82 2014-08-08T15:18:40 For negative matches, always use leading dir match
Russell Belfer f25bc0b2 2014-08-08T14:51:36 Fix rejection of parent dir of negated ignores While scanning through a directory hierarchy, this prevents a positive ignore match on a parent directory from blocking the scan of a directory when a negative match rule exists for files inside the directory.
Russell Belfer 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.
Russell Belfer 17ef678c 2014-04-21T11:55:57 Fix some coverity-found issues
Russell Belfer ac16bd0a 2014-04-18T15:45:59 Minor fixes Only apply LEADING_DIR pattern munging to patterns in ignore and attribute files, not to pathspecs used to select files to operate on. Also, allow internal macro definitions to be evaluated before loading all external ones (important so that external ones can make use of internal `binary` definition).
Russell Belfer 916fcbd6 2014-04-18T14:42:40 Fix ignore difference from git with trailing /* Ignore patterns that ended with a trailing '/*' were still needing to match against another actual '/' character in the full path. 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.
Russell Belfer e3a2a04c 2014-04-18T14:29:58 Preload attribute files that may contain macros There was a latent bug where files that use macro definitions could be parsed before the macro definitions were loaded. Because of attribute file caching, preloading files that are going to be used doesn't add a significant amount of overhead, so let's always preload any files that could contain macros before we assemble the actual vector of files to scan for attributes.
Russell Belfer 823c0e9c 2014-04-17T11:53:13 Fix broken logic for attr cache invalidation The checks to see if files were out of date in the attibute cache was wrong because the cache-breaker data wasn't getting stored correctly. Additionally, when the cache-breaker triggered, the old file data was being leaked.
Russell Belfer e6e8530a 2014-04-14T12:31:17 Lock attribute file while reparsing data I don't love this approach, but achieving thread-safety for attribute and ignore data while reloading files would require a larger rewrite in order to avoid this. If an attribute or ignore file is out of date, this holds a lock on the file while we are reloading the data so that another thread won't try to reload the data at the same time.
Russell Belfer 2e9d813b 2014-04-11T12:12:47 Fix tests with new attr cache code
Russell Belfer 7d490872 2014-04-10T22:31:01 Attribute file cache refactor This is a big refactoring of the attribute file cache to be a bit simpler which in turn makes it easier to enforce a lock around any updates to the cache so that it can be used in a threaded env. Tons of changes to the attributes and ignores code.
Russell Belfer 40ed4990 2014-02-11T14:45:37 Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.
Russell Belfer 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.
Linquize 66566516 2013-09-08T17:15:42 Fix warning
Russell Belfer 4ba64794 2013-08-09T10:52:35 Revert PR #1462 and provide alternative fix This rolls back the changes to fnmatch parsing from commit 2e40a60e847d6c128af23e24ea7a8efebd2427da except for the tests that were added. Instead this adds couple of new flags that can be passed in when attempting to parse an fnmatch pattern. Also, this changes the pathspec match logic to special case matching a filename with a '!' prefix against a negative pattern. This fixes the build.
Russell Belfer 33d532dc 2013-08-09T09:32:06 Merge pull request #1462 from yorah/fix/libgit2sharp-issue-379 status: fix handling of filenames with special prefixes
Russell Belfer 22b6b82f 2013-06-20T12:16:06 Add status flags to force output sort order Files in status will, be default, be sorted according to the case insensitivity of the filesystem that we're running on. However, in some cases, this is not desirable. Even on case insensitive file systems, 'git status' at the command line will generally use a case sensitive sort (like 'ls'). Some GUIs prefer to display a list of file case insensitively even on case-sensitive platforms. This adds two new flags: GIT_STATUS_OPT_SORT_CASE_SENSITIVELY and GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY that will override the default sort order of the status output and give the user control. This includes tests for exercising these new options and makes the examples/status.c program emulate core Git and always use a case sensitive sort.

Russell Belfer 5540d947 2013-03-15T16:39:00 Implement global/system file search paths The goal of this work is to expose the search logic for "global", "system", and "xdg" files through the git_libgit2_opts() interface. Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places.

Russell Belfer ca1b6e54 2012-07-31T17:02:54 Add template dir and set gid to repo init This extends git_repository_init_ext further with support for initializing the repository from an external template directory and with support for the "create shared" type flags that make a set GID repository directory. This also adds tests for much of the new functionality to the existing `repo/init.c` test suite. Also, this adds a bunch of new utility functions including a very general purpose `git_futils_mkdir` (with the ability to make paths and to chmod the paths post-creation) and a file tree copying function `git_futils_cp_r`. Also, this includes some new path functions that were useful to keep the code simple.

Russell Belfer 2a99df69 2012-05-24T17:14:56 Fix bugs for status with spaces and reloaded attrs 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.

Russell Belfer 41a82592 2012-05-15T14:17:39 Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

Russell Belfer f917481e 2012-05-03T16:37:25 Support reading attributes from index Depending on the operation, we need to consider gitattributes in both the work dir and the index. This adds a parameter to all of the gitattributes related functions that allows user control of attribute reading behavior (i.e. prefer workdir, prefer index, only use index). This fix also covers allowing us to check attributes (and hence do diff and status) on bare repositories. This was a somewhat larger change that I hoped because it had to change the cache key used for gitattributes files.

Russell Belfer 01fed0a8 2012-04-25T10:36:01 Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.
Russell Belfer 19fa2bc1 2012-04-17T15:12:50 Convert attrs and diffs to use string pools This converts the git attr related code (including ignores) and the git diff related code (and implicitly the status code) to use `git_pools` for storing strings. This reduces the number of small blocks allocated dramatically.
Russell Belfer 14a513e0 2012-04-13T15:00:29 Add support for pathspec to diff and status This adds preliminary support for pathspecs to diff and status. The implementation is not very optimized (it still looks at every single file and evaluated the the pathspec match against them), but it works.
Russell Belfer 95dfb031 2012-03-30T14:40:50 Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.

Vicent Martí c63793ee 2012-03-02T03:51:45 attr: Change the attribute check macros The point of having `GIT_ATTR_TRUE` and `GIT_ATTR_FALSE` macros is to be able to change the way that true and false values are stored inside of the returned gitattributes value pointer. However, if these macros are implemented as a simple rename for the `git_attr__true` pointer, they will always be used with the `==` operator, and hence we cannot really change the implementation to any other way that doesn't imply using special pointer values and comparing them! We need to do the same thing that core Git does, which is using a function macro. With `GIT_ATTR_TRUE(attr)`, we can change internally the way that these values are stored to anything we want. This commit does that, and rewrites a large chunk of the attributes test suite to remove duplicated code for expected attributes, and to properly test the function macro behavior instead of comparing pointers.
Vicent Martí 13224ea4 2012-02-27T04:28:31 buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.
Russell Belfer e4eb94a2 2012-01-31T14:02:52 Fix issue with ignoring whole directories Now that is_dir is calculated correctly for attr/ignore paths, it is possible to use it so that ignoring "dir/" will properly match the directory name and ignore the entire directory.
Russell Belfer adc9bdb3 2012-01-31T13:59:32 Fix attr path is_dir check When building an attr path object, the code that checks if the file is a directory was evaluating the file as a relative path to the current working directory, instead of using the repo root. This lead to inconsistent behavior.

Russell Belfer 1744fafe 2012-01-17T15:49:47 Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
Russell Belfer 83bfbdf5 2012-01-16T18:00:18 Remove poor git__removechar function Going back over this, the git__removechar function was not needed (only invoked once) and is actually mislabeled. As implemented, it really only made sense for removing backslash characters, since two of the "removed" characters in a row would include the second one -- i.e. it really implements stripping backslash-escaped strings where a backslash allows internal whitespace in a word.
Russell Belfer a51cd8e6 2012-01-16T16:58:27 Fix handling of relative paths for attrs Per issue #533, the handling of relative paths in attribute and ignore files was not right. Fixed this by pre-joining the relative path of the attribute/ignore file onto the match string when a full path match is required. Unfortunately, fixing this required a bit more code than I would have liked because I had to juggle things around so that the fnmatch parser would have sufficient information to prepend the relative path when it was needed.
Russell Belfer df743c7d 2012-01-09T15:37:19 Initial implementation of gitignore support Adds support for .gitignore files to git_status_foreach() and git_status_file(). This includes refactoring the gitattributes code to share logic where possible. The GIT_STATUS_IGNORED flag will now be passed in for files that are ignored (provided they are not already in the index or the head of repo).
Russell Belfer bd370b14 2011-12-30T15:00:14 Improved gitattributes macro implementation This updates to implementation of gitattribute macros to be much more similar to core git (albeit not 100%) and to handle expansion of macros within macros, etc. It also cleans up the refcounting usage with macros to be much cleaner. Also, this adds a new vector function `git_vector_insert_sorted()` which allows you to maintain a sorted list as you go. In order to write that function, this changes the function `git__bsearch()` to take a somewhat different set of parameters, although the core functionality is still the same.
Russell Belfer c6d2a2c0 2011-12-29T21:31:30 Fixed up memory leaks
Russell Belfer 73b51450 2011-12-28T23:28:50 Add support for macros and cache flush API. Add support for git attribute macro definitions. Also, add support for cache flush API to clear the attribute file content cache when needed. Additionally, improved the handling of global and system files, making common utility functions in fileops and converting config and attr to both use the common functions. Adds a bunch more tests and fixed some memory leaks. Note that adding macros required me to use refcounted attribute assignment definitions, which complicated, but probably improved memory usage.
Russell Belfer ee1f0b1a 2011-12-16T10:56:43 Add APIs for git attributes This adds APIs for querying git attributes. In addition to the new API in include/git2/attr.h, most of the action is in src/attr_file.[hc] which contains utilities for dealing with a single attributes file, and src/attr.[hc] which contains the implementation of the APIs that merge all applicable attributes files.
