|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new command "git check-ignore" for debugging .gitignore files.

| | | | | | | | | | | | | | | | | | By the end of a directory traversal, a dir_struct instance will typically contains pointers to various data structures on the heap. clear_directory() provides a convenient way to reclaim that memory.

| * dir.c: keep track of where patterns came fromAdam Spiers2013-01-061-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For exclude patterns read in from files, the filename is stored in the exclude list, and the originating line number is stored in the individual exclude (counting starting at 1). For exclude patterns provided on the command line, a string describing the source of the patterns is stored in the exclude list, and the sequence number assigned to each exclude pattern is negative, with counting starting at -1. So for example the 2nd pattern provided via --exclude would be numbered -2. This allows any future consumers of that data to easily distinguish between exclude patterns from files vs. from the CLI.

| * dir.c: use a single struct exclude_list per source of excludesAdam Spiers2013-01-061-10/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously each exclude_list could potentially contain patterns from multiple sources. For example dir->exclude_list[EXC_FILE] would typically contain patterns from .git/info/exclude and core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain patterns from multiple per-directory .gitignore files during directory traversal (i.e. when dir->exclude_stack was more than one item deep). We split these composite exclude_lists up into three groups of exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each exclude_list now contains patterns from a single source. This will allow us to cleanly track the origin of each pattern simply by adding a src field to struct exclude_list, rather than to struct exclude, which would make memory management of the source string tricky in the EXC_DIRS case where its contents are dynamically generated. Similarly, by moving the filebuf member from struct exclude_stack to struct exclude_list, it allows us to track and subsequently free memory buffers allocated during the parsing of all exclude files, rather than only tracking buffers allocated for files in the EXC_DIRS group.

| | | | | | | | | | | | | | | | | | | | | | | | It is clearer to use a 'clear_' prefix for functions which empty and deallocate the contents of a data structure without freeing the structure itself, and a 'free_' prefix for functions which also free the structure itself. http://article.gmane.org/gmane.comp.version-control.git/206128 Signed-off-by: Adam Spiers <git@adamspiers.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * dir.c: refactor is_path_excluded()Adam Spiers2012-12-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a similar way to the previous commit, this extracts a new helper function last_exclude_matching_path() which return the last exclude_list element which matched, or NULL if no match was found. is_path_excluded() becomes a wrapper around this, and just returns 0 or 1 depending on whether any matching exclude_list element was found. This allows callers to find out _why_ a given path was excluded, rather than just whether it was or not, paving the way for a new git sub-command which allows users to test their exclude lists from the command line.

* attr: more matching optimizations from .gitignoreNguyễn Thái Ngọc Duy2012-10-151-0/+11
| | | | | | | | | | | | | | | | | | | | | | | .gitattributes and .gitignore share the same pattern syntax but has separate matching implementation. Over the years, ignore's implementation accumulates more optimizations while attr's stays the same. This patch reuses the core matching functions that are also used by excluded_from_list. excluded_from_list and path_matches can't be merged due to differences in exclude and attr, for example: * "!pattern" syntax is forbidden in .gitattributes. As an attribute can be unset (i.e. set to a special value "false") or made back to unspecified (i.e. not even set to "false"), "!pattern attr" is unclear which one it means. * we support attaching attributes to directories, but git-core internally does not currently make use of attributes on directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "git ls-files --exclude=t/ -i" does not show paths in directory t/ that have been added to the index, but it should. The excluded() API was designed for callers who walk the tree from the top, checking each level of the directory hierarchy as it descends if it is excluded, and not even bothering to recurse into an excluded directory. This would allow us optimize for a common case by not having to check if the exclude pattern "foo/" matches when looking at "foo/bar", because the caller should have noticed that "foo" is excluded and did not even bother to read "foo/bar" out of opendir()/readdir() to call it. The code for "ls-files -i" however walks the index linearly, feeding paths without checking if the leading directory is already excluded. Introduce a helper function path_excluded() to let this caller properly call excluded() check for higher hierarchies as necessary. Signed-off-by: Junio C Hamano <gitster@pobox.com>

|/ | | | | | | | | | | | | | | | | | | Multiple locations within this patch series alter a case sensitive string comparison call such as strcmp() to be a call to a string comparison call that selects case comparison based on the global ignore_case variable.

When core.ignorecase=true, the *_icase() versions perform a case insensitive comparison. Like Linus' earlier ignorecase patch, these may ignore filename conventions on certain file systems. By isolating filename comparisons to certain functions, support for those filename conventions may be more easily met.

* Add 'fill_directory()' helper function for directory traversalLinus Torvalds2009-07-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | Most of the users of "read_directory()" actually want a much simpler interface than the whole complex (but rather powerful) one. In fact 'git add' had already largely abstracted out the core interface issues into a private "fill_directory()" function that was largely applicable almost as-is to a number of callers. Yes, 'git add' wants to do some extra work of its own, specific to the add semantics, but we can easily split that out, and use the core as a generic function. This function does exactly that, and now that much simplified 'fill_directory()' function can be shared with a number of callers, while also ensuring that the rather more complex calling conventions of read_directory() are used by fewer call-sites. This also makes the 'common_prefix()' helper function private to dir.c, since all callers are now in that file.

This attempts to extend the exclude mechanism so that it would while not matching a regular file or a symbolic link "foo". In order to differentiate a directory and non directory, this passes down the type of path being checked to excluded() function. A downside is that the recursive directory walk may need to run lstat(2) more often on systems whose "struct dirent" do not give the type of the entry; earlier it did not have to do so for an excluded path, but we now need to figure out if a path is a directory before deciding to exclude it. This is especially bad because an idea similar to the earlier CE_UPTODATE optimization to reduce number of lstat(2) calls would by definition not apply to the codepaths involved, as (1) directories will not be registered in the index, and (2) excluded paths will not be in the index anyway.

* per-directory-exclude: lazily read .gitignore filesJunio C Hamano2007-11-291-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | Operations that walk directories or trees, which potentially need to consult the .gitignore files, used to always try to open the .gitignore file every time they entered a new directory, even when they ended up not needing to call excluded() function to see if a path in the directory is ignored. This was done by push/pop exclude_per_directory() functions that managed the data in a stack. This changes the directory walking API to remove the need to call these two functions. Instead, the directory walk data structure caches the data used by excluded() function the last time, and lazily reuses it as much as possible. Among the data the last check used, the ones from deeper directories that the path we are checking is outside are discarded, data from the common leading directories are reused, and then the directories between the common directory and the directory the path being checked is in are checked for .gitignore file. This is very similar to the way gitattributes are handled. This API change also fixes "ls-files -c -i", which called excluded() without setting up the gitignore data via the old push/pop functions.

* core.excludesfile clean-upJunio C Hamano2007-11-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are inconsistencies in the way commands currently handle the core.excludesfile configuration variable. The problem is the variable is too new to be noticed by anything other than git-add and git-status. * git-ls-files does not notice any of the "ignore" files by default, as it predates the standardized set of ignore files. The calling scripts established the convention to use .git/info/exclude, .gitignore, and later core.excludesfile. * git-add and git-status know about it because they call add_excludes_from_file() directly with their own notion of which standard set of ignore files to use. This is just a stupid duplication of code that need to be updated every time the definition of the standard set of ignore files is changed. * git-read-tree takes --exclude-per-directory=<gitignore>, not because the flexibility was needed. Again, this was because the option predates the standardization of the ignore files. * git-merge-recursive uses hardcoded per-directory .gitignore and nothing else. git-clean (scripted version) does not honor core.* because its call to underlying ls-files does not know about it. git-clean in C (parked in 'pu') doesn't either. We probably could change git-ls-files to use the standard set when no excludes are specified on the command line and ignore processing was asked, or something like that, but that will be a change in semantics and might break people's scripts in a subtle way. I am somewhat reluctant to make such a change. On the other hand, I think it makes perfect sense to fix git-read-tree, git-merge-recursive and git-clean to follow the same rule as other commands. I do not think of a valid use case to give an exclude-per-directory that is nonstandard to read-tree command, outside a "negative" test in the t1004 test script. This patch is the first step to untangle this mess. The next step would be to teach read-tree, merge-recursive and clean (in C) to use setup_standard_excludes().

* Speedup scanning for excluded files.Lars Knoll2007-10-291-0/+7
| | | | | | | | | | | | Try to avoid a lot of work scanning for excluded files, by caching some more information when setting up the exclusion data structure. Speeds up 'git runstatus' on a repository containing the Qt sources by 30% and reduces the amount of instructions executed (as measured by valgrind) by a factor of 2.
