2013-03-28dir.c::match_pathname(): pay attention to the length of string parametersLibravatar Jeff King1-1/+12
This function takes two counted strings: a <pattern, patternlen> pair and a <pathname, pathlen> pair. But we end up feeding the result to fnmatch, which expects NUL-terminated strings. We can fix this by calling the fnmatch_icase_mem function, which handles re-allocating into a NUL-terminated string if necessary. While we're at it, we can avoid even calling fnmatch in some cases. In addition to patternlen, we get "prefix", the size of the pattern that contains no wildcard characters. We do a straight match of the prefix part first, and then use fnmatch to cover the rest. But if there are no wildcards in the pattern at all, we do not even need to call fnmatch; we would simply be comparing two empty strings.

2013-03-28dir.c::match_pathname(): adjust patternlen when shifting patternLibravatar Jeff King1-0/+1
If we receive a pattern that starts with "/", we shift it forward to avoid looking at the "/" part. Since the prefix and patternlen parameters are counts of what is in the pattern, we must decrement them as we increment the pointer. We remembered to handle prefix, but not patternlen. This didn't cause any bugs, though, because the patternlen parameter is not actually used. Since it will be used in future patches, let's correct this oversight.

2013-03-28dir.c::match_basename(): pay attention to the length of string parametersLibravatar Junio C Hamano1-4/+36
The function takes two counted strings (<basename, basenamelen> and <pattern, patternlen>) as parameters, together with prefix (the length of the prefix in pattern that is to be matched literally without globbing against the basename) and EXC_* flags that tells it how to match the pattern against the basename. However, it did not pay attention to the length of these counted strings. Update them to do the following: * When the entire pattern is to be matched literally, the pattern matches the basename only when the lengths of them are the same, and they match up to that length. * When the pattern is "*" followed by a string to be matched literally, make sure that the basenamelen is equal or longer than the "literal" part of the pattern, and the tail of the basename string matches that literal part. * Otherwise, use the new fnmatch_icase_mem helper to make sure we only lookmake sure we use only look at the counted part of the strings. Because these counted strings are full strings most of the time, we check for termination to avoid unnecessary allocation.

2013-01-07status: always report ignored tracked directoriesLibravatar Antoine Pelisse1-6/+3
When enumerating paths that are ignored, paths the index knows about are not included in the result. The "index knows about" check is done by consulting the name hash, not the actual contents of the index: - When core.ignorecase is false, directory names are not in the name hash, and ignored ones are shown as ignored (directories can never be tracked anyway). - When core.ignorecase is true, however, the name hash keeps track of the names of directories, in order to detect additions of the paths under different cases. This causes ignored directories to be mistakenly excluded when enumerating ignored paths. Stop excluding directories that are in the name hash when looking for ignored files in dir_add_name(); the names that are actually in the index are excluded much earlier in the callchain in treat_file(), so this fix will not make them mistakenly identified as ignored.

2013-01-06dir.c: keep track of where patterns came fromLibravatar Adam Spiers1-6/+20
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 Spiers1-19/+45
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.

2013-01-01dir.c: Make git-status --ignored more consistentLibravatar Antoine Pelisse1-20/+78
The current behavior of git-status is inconsistent and misleading. Especially when used with --untracked-files=all option: - files ignored in untracked directories will be missing from status output. - untracked files in committed yet ignored directories are also missing. - with --untracked-files=normal, untracked directories that contains only ignored files are dropped too. Make the behavior more consistent across all possible use cases: - "--ignored --untracked-files=normal" doesn't show each specific files but top directory. It instead shows untracked directories that only contains ignored files, and ignored tracked directories with untracked files. - "--ignored --untracked-files=all" shows all ignored files, either because it's in an ignored directory (tracked or untracked), or because the file is explicitly ignored.

2012-12-28dir.c: refactor is_excluded_from_list()Libravatar Adam Spiers1-9/+28
The excluded function uses a new helper function called last_exclude_matching_from_list() to perform the inner loop over all of the exclude patterns. The helper just tells us whether the path is included, excluded, or undecided. However, it may be useful to know _which_ pattern was triggered. So let's pass out the entire exclude match, which contains the status information we were already passing out. Further patches can make use of this.

2012-12-19add global --literal-pathspecs optionLibravatar Jeff King1-6/+19
Git takes pathspec arguments in many places to limit the scope of an operation. These pathspecs are treated not as literal paths, but as glob patterns that can be fed to fnmatch. When a user is giving a specific pattern, this is a nice feature. However, when programatically providing pathspecs, it can be a nuisance. For example, to find the latest revision which modified "$foo", one can use "git rev-list -- $foo". But if "$foo" contains glob characters (e.g., "f*"), it will erroneously match more entries than desired. The caller needs to quote the characters in $foo, and even then, the results may not be exactly the same as with a literal pathspec. For instance, the depth checks in match_pathspec_depth do not kick in if we match via fnmatch. This patch introduces a global command-line option (i.e., one for "git" itself, not for specific commands) to turn this behavior off. It also has a matching environment variable, which can make it easier if you are a script or porcelain interface that is going to issue many such commands. This option cannot turn off globbing for particular pathspecs. That could eventually be done with a ":(noglob)" magic pathspec prefix. However, that level of granularity is more cumbersome to use for many cases, and doing ":(noglob)" right would mean converting the whole codebase to use "struct pathspec", as the usual "const char **pathspec" cannot represent extra per-item flags.

2012-11-26pathspec: apply "*.c" optimization from excludeLibravatar Nguyễn Thái Ngọc Duy1-2/+16
When a pattern contains only a single asterisk as wildcard, e.g. "foo*bar", after literally comparing the leading part "foo" with the string, we can compare the tail of the string and make sure it matches "bar", instead of running fnmatch() on "*bar" against the remainder of the string. -O2 build on linux-2.6, without the patch: $ time git rev-list --quiet HEAD -- '*.c' real 0m40.770s user 0m40.290s sys 0m0.256s With the patch $ time ~/w/git/git rev-list --quiet HEAD -- '*.c' real 0m34.288s user 0m33.997s sys 0m0.205s The above command is not supposed to be widely popular. It's chosen because it exercises pathspec matching a lot. The point is it cuts down matching time for popular patterns like *.c, which could be used as pathspec in other places.

Teach git to read various information from $XDG_CONFIG_HOME/git/ to allow the user to avoid cluttering $HOME. * mm/config-xdg: config: write to $XDG_CONFIG_HOME/git/config file when appropriate Let core.attributesfile default to $XDG_CONFIG_HOME/git/attributes Let core.excludesfile default to $XDG_CONFIG_HOME/git/ignore config: read (but not write) from $XDG_CONFIG_HOME/git/config file

Attempt to optimize matching with an exclude pattern with a deep directory hierarchy by taking the part that specifies leading path without wildcard literally.
2012-06-25Let core.excludesfile default to $XDG_CONFIG_HOME/git/ignoreLibravatar Huynh Khoi Nguyen Nguyen1-1/+6
To use the feature of core.excludesfile, the user needs: 1. to create such a file, 2. and add configuration variable to point at it. Instead, we can make this a one-step process by choosing a default value which points to a filename in the user's $HOME, that is unlikely to already exist on the system, and only use the presence of the file as a cue that the user wants to use that feature. And we use "${XDG_CONFIG_HOME:-$HOME/.config/git}/ignore" as such a file, in the same directory as the newly added configuration file ("${XDG_CONFIG_HOME:-$HOME/.config/git}/config). The use of this directory is in line with XDG specification as a location to store such application specific files.
