2014-07-14prep_exclude: remove the artificial PATH_MAX limitLibravatar Nguyễn Thái Ngọc Duy1-1/+1
This fixes a segfault in git-status with long paths on Windows, where PATH_MAX is only 260. This also fixes the problem of silently ignoring .gitignore if the full path exceeds PATH_MAX. Now add_excludes_from_file() will report if it gets ENAMETOOLONG.

2014-02-24pathspec: pass directory indicator to match_pathspec_item()Libravatar Nguyễn Thái Ngọc Duy1-3/+7
This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce the same output. Previously only the version without trailing slash returns the difference (if any). That's the effect of new ce_path_match(). dir_path_match() is not executed by the new tests. And it should not introduce regressions. Previously if path "dir/" is passed in with pathspec "dir/", they obviously match. With new dir_path_match(), the path becomes _directory_ "dir" vs pathspec "dir/", which is not executed by the old code path in m_p_i(). The new code path is executed and produces the same result. The other case is pathspec "dir" and path "dir/" is now turned to "dir" (with DO_MATCH_DIRECTORY). Still the same result before or after the patch. So why change? Because of the next patch about clean.c. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

"git ls-files -k" needs to crawl only the part of the working tree that may overlap the paths in the index to find killed files, but shared code with the logic to find all the untracked files, which made it unnecessarily inefficient. * jc/ls-files-killed-optim: dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage t3010: update to demonstrate "ls-files -k" optimization pitfalls ls-files -k: a directory only can be killed if the index has a non-directory dir.c: use the cache_* macro to access the current index
2013-08-15ls-files -k: a directory only can be killed if the index has a non-directoryLibravatar Junio C Hamano1-1/+2
"ls-files -o" and "ls-files -k" both traverse the working tree down to find either all untracked paths or those that will be "killed" (removed from the working tree to make room) when the paths recorded in the index are checked out. It is necessary to traverse the working tree fully when enumerating all the "other" paths, but when we are only interested in "killed" paths, we can take advantage of the fact that paths that do not overlap with entries in the index can never be killed. The treat_one_path() helper function, which is called during the recursive traversal, is the ideal place to implement an optimization. When we are looking at a directory P in the working tree, there are three cases: (1) P exists in the index. Everything inside the directory P in the working tree needs to go when P is checked out from the index. (2) P does not exist in the index, but there is P/Q in the index. We know P will stay a directory when we check out the contents of the index, but we do not know yet if there is a directory P/Q in the working tree to be killed, so we need to recurse. (3) P does not exist in the index, and there is no P/Q in the index to require P to be a directory, either. Only in this case, we know that everything inside P will not be killed without recursing. Note that this helper is called by treat_leading_path() that decides if we need to traverse only subdirectories of a single common leading directory, which is essential for this optimization to be correct. This caller checks each level of the leading path component from shallower directory to deeper ones, and that is what allows us to only check if the path appears in the index. If the call to treat_one_path() weren't there, given a path P/Q/R, the real traversal may start from directory P/Q/R, even when the index records P as a regular file, and we would end up having to check if any leading subpath in P/Q/R, e.g. P, appears in the index.

2013-07-15pathspec: support :(glob) syntaxLibravatar Nguyễn Thái Ngọc Duy1-5/+4
:(glob)path differs from plain pathspec that it uses wildmatch with WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The difference lies in how '*' (and '**') is processed. With the introduction of :(glob) and :(literal) and their global options --[no]glob-pathspecs, the user can: - make everything literal by default via --noglob-pathspecs --literal-pathspecs cannot be used for this purpose as it disables _all_ pathspec magic. - individually turn on globbing with :(glob) - make everything globbing by default via --glob-pathspecs - individually turn off globbing with :(literal) The implication behind this is, there is no way to gain the default matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get new globbing or literal. The old fnmatch behavior is considered deprecated and discouraged to use.

2013-07-15add parse_pathspec() that converts cmdline args to struct pathspecLibravatar Nguyễn Thái Ngọc Duy1-0/+2
Currently to fill a struct pathspec, we do: const char **paths; paths = get_pathspec(prefix, argv); ... init_pathspec(&pathspec, paths); "paths" can only carry bare strings, which loses information from command line arguments such as pathspec magic or the prefix part's length for each argument. parse_pathspec() is introduced to combine the two calls into one. The plan is gradually replace all get_pathspec() and init_pathspec() with parse_pathspec(). get_pathspec() now becomes a thin wrapper of parse_pathspec(). parse_pathspec() allows the caller to reject the pathspec magics that it does not support. When a new pathspec magic is introduced, we can enable it per command after making sure that all underlying code has no problem with the new magic. "flags" parameter is currently unused. But it would allow callers to pass certain instructions to parse_pathspec, for example forcing literal pathspec when no magic is used. With the introduction of parse_pathspec, there are now two functions that can initialize struct pathspec: init_pathspec and parse_pathspec. Any semantic changes in struct pathspec must be reflected in both functions. init_pathspec() will be phased out in favor of parse_pathspec().

2013-04-15dir.c: git-status --ignored: don't scan the work tree twiceLibravatar Karsten Blees1-1/+2
'git-status --ignored' still scans the work tree twice to collect untracked and ignored files, respectively. fill_directory / read_directory already supports collecting untracked and ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED flag to enable this has some git-add specific side-effects (e.g. it doesn't recurse into ignored directories, so listing ignored files with --untracked=all doesn't work). The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored files in dir_struct.entries[] (instead of dir_struct.ignored[] as DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git. We don't want to break the existing API, so lets introduce a new flag DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar to DIR_COLLECT_FILES, but will recurse into sub-directories based on the other flags as DIR_SHOW_IGNORED does. In dir.c::read_directory_recursive, add ignored files to either dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move the DIR_COLLECT_IGNORED case here so that filling result lists is in a common place. In wt-status.c::wt_status_collect_untracked, use the new flag and read results from dir_struct.ignored[]. Remove the extra fill_directory call. builtin/check-ignore.c doesn't call fill_directory, setting the git-add specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity. Update API documentation to reflect the changes. Performance: with this patch, 'git-status --ignored' is typically as fast as 'git-status'.

2013-04-15dir.c: unify is_excluded and is_path_excluded APIsLibravatar Karsten Blees1-3/+3
The is_excluded and is_path_excluded APIs are very similar, except for a few noteworthy differences: is_excluded doesn't handle ignored directories, results for paths within ignored directories are incorrect. This is probably based on the premise that recursive directory scans should stop at ignored directories, which is no longer true (in certain cases, read_directory_recursive currently calls is_excluded *and* is_path_excluded to get correct ignored state). is_excluded caches parsed .gitignore files of the last directory in struct dir_struct. If the directory changes, it finds a common parent directory and is very careful to drop only as much state as necessary. On the other hand, is_excluded will also read and parse .gitignore files in already ignored directories, which are completely irrelevant. is_path_excluded correctly handles ignored directories by checking if any component in the path is excluded. As it uses is_excluded internally, this unfortunately forces is_excluded to drop and re-read all .gitignore files, as there is no common parent directory for the root dir. is_path_excluded tracks state in a separate struct path_exclude_check, which is essentially a wrapper of dir_struct with two more fields. However, as is_path_excluded also modifies dir_struct, it is not possible to e.g. use multiple path_exclude_check structures with the same dir_struct in parallel. The additional structure just unnecessarily complicates the API. Teach is_excluded / prep_exclude about ignored directories: whenever entering a new directory, first check if the entire directory is excluded. Remember the excluded state in dir_struct. Don't traverse into already ignored directories (i.e. don't read irrelevant .gitignore files). Directories could also be excluded by exclude patterns specified on the command line or .git/info/exclude, so we cannot simply skip prep_exclude entirely if there's no .gitignore file name (dir_struct.exclude_per_dir). Move this check to just before actually reading the file. is_path_excluded is now equivalent to is_excluded, so we can simply redirect to it (the public API is cleaned up in the next patch). The performance impact of the additional ignored check per directory is hardly noticeable when reading directories recursively (e.g. 'git status'). However, performance of git commands using the is_path_excluded API (e.g. 'git ls-files --cached --ignored --exclude-standard') is greatly improved as this no longer re-reads .gitignore files on each call.

2013-01-06dir.c: keep track of where patterns came fromLibravatar Adam Spiers1-2/+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.

2013-01-06dir.c: use a single struct exclude_list per source of excludesLibravatar Adam Spiers1-10/+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.

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.

"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>

2011-09-06consolidate pathspec_prefix and common_prefixLibravatar Junio C Hamano1-0/+1
The implementation from pathspec_prefix (slightly modified) replaces the current common_prefix, because it also respects glob characters. Based on a patch by Clemens Buchacher. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* nd/maint-setup: Kill off get_relative_cwd() setup: return correct prefix if worktree is '/' Conflicts: dir.c setup.c
2011-03-28Kill off get_relative_cwd()Libravatar Nguyễn Thái Ngọc Duy1-1/+0
Function dir_inside_of() does something similar (correctly), but looks easier to understand and does not bundle cwd to its business. Given get_relative_cwd's only user is is_inside_dir, we can kill it for good. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-28setup: return correct prefix if worktree is '/'Libravatar Nguyễn Thái Ngọc Duy1-0/+1
The same old problem reappears after setup code is reworked. We tend to assume there is at least one path component in a path and forget that path can be simply '/'.

2011-02-03pathspec: add match_pathspec_depth()Libravatar Nguyễn Thái Ngọc Duy1-0/+3
match_pathspec_depth() is a clone of match_pathspec() except that it can take depth limit. Computation is a bit lighter compared to match_pathspec() because it's usually precomputed and stored in struct pathspec. In long term, match_pathspec() and match_one() should be removed in favor of this function. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-02-03tree_entry_interesting(): support depth limitLibravatar Nguyễn Thái Ngọc Duy1-0/+1
This is needed to replace pathspec_matches() in builtin/grep.c. max_depth == -1 means infinite depth. Depth limit is only effective when pathspec.recursive == 1. When pathspec.recursive == 0, the behavior depends on match functions: non-recursive for tree_entry_interesting() and recursive for match_pathspec{,_depth} Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-10-06Add string comparison functions that respect the ignore_case variable.Libravatar Joshua Jensen1-0/+4
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. Behaviorally, when core.ignorecase=false, the *_icase() versions are functionally equivalent to their C runtime counterparts. 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.
