2015-04-22ignore: info/exclude should trump core.excludesfileLibravatar Junio C Hamano1-3/+7
$GIT_DIR/info/exclude and core.excludesfile (which falls back to $XDG_HOME/git/ignore) are both ways to override the ignore pattern lists given by the project in .gitignore files. The former, which is per-repository personal preference, should take precedence over the latter, which is a personal preference default across different repositories that are accessed from that machine. The existing documentation also agrees. However, the precedence order was screwed up between these two from the very beginning when 896bdfa2 (add: Support specifying an excludes file with a configuration variable, 2007-02-27) introduced core.excludesfile variable.

2015-04-16add_excludes_from_file: clarify the bom skipping logicLibravatar Junio C Hamano1-4/+5
Even though the previous step shifts where the "entry" begins, we still iterate over the original buf[], which may begin with the UTF-8 BOM we are supposed to be skipping. At the end of the first line, the code grabs the contents of it starting at "entry", so there is nothing wrong per-se, but the logic looks really confused. Instead, move the buf pointer and shrink its size, to truly pretend that UTF-8 BOM did not exist in the input. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-04-16dir: allow a BOM at the beginning of exclude filesLibravatar Carlos Martín Nieto1-1/+7
Some text editors like Notepad or LibreOffice write an UTF-8 BOM in order to indicate that the file is Unicode text rather than whatever the current locale would indicate. If someone uses such an editor to edit a gitignore file, we are left with those three bytes at the beginning of the file. If we do not skip them, we will attempt to match a filename with the BOM as prefix, which won't match the files the user is expecting.

2015-03-24report_path_error(): move to dir.cLibravatar Junio C Hamano1-0/+43
The expected call sequence is for the caller to use match_pathspec() repeatedly on a set of pathspecs, accumulating the "hits" in a separate array, and then call this function to diagnose a pathspec that never matched anything, as that can indicate a typo from the command line, e.g. "git commit Maekfile". Many builtin commands use this function from builtin/ls-files.c, which is not a very healthy arrangement. ls-files might have been the first command to feel the need for such a helper, but the need is shared by everybody who uses the "match and then report" pattern. Move it to dir.c where match_pathspec() is defined. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-20cleanup duplicate name_compare() functionsLibravatar Jeremiah Mahler1-2/+1
We often represent our strings as a counted string, i.e. a pair of the pointer to the beginning of the string and its length, and the string may not be NUL terminated to that length. To compare a pair of such counted strings, unpack-trees.c and read-cache.c implement their own name_compare() functions identically. In addition, the cache_name_compare() function in read-cache.c is nearly identical. The only difference is when one string is the prefix of the other string, in which case name_compare() returns -1/+1 to show which one is longer, and cache_name_compare() returns the difference of the lengths to show the same information. Unify these three functions by using the implementation from cache_name_compare(). This does not make any difference to the existing and future callers, as they must be paying attention only to the sign of the returned value (and not the magnitude) because the original implementations of these two functions return values returned by memcmp(3) when the one string is not a prefix of the other string, and the only thing memcmp(3) guarantees its callers is the sign of the returned value, not the magnitude.

Discard the unnecessary 'nr_spaces' variable, remove 'strlen()' and improve the 'if' structure. Switch to pointers instead of integers to control the loop. Slightly more rare occurrences of 'text \ ' with a backslash in between spaces are handled correctly. Namely, the code in 7e2e4b37 (dir: ignore trailing spaces in exclude patterns, 2014-02-09) does not reset 'last_space' when a backslash is encountered and the above line stays intact as a result.

2014-02-24pathspec: pass directory indicator to match_pathspec_item()Libravatar Nguyễn Thái Ngọc Duy1-2/+2
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?

2013-09-17dir: revert work-around for retired dangerous behaviorLibravatar Eric Sunshine1-15/+3
directory_exists_in_index_icase() dangerously assumed that it could access one character beyond the end of its directory argument, and that that character would unconditionally be '/'. 2eac2a4c (ls-files -k: a directory only can be killed if the index has a non-directory, 2013-08-15) added a caller which did not respect this undocumented assumption, and 680be044 (dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage, 2013-08-23) added a work-around which temporarily appends a '/' before invoking directory_exists_in_index_icase().

2013-09-17name-hash: stop storing trailing '/' on paths in index_state.dir_hashLibravatar Eric Sunshine1-1/+1
When 5102c617 (Add case insensitivity support for directories when using git status, 2010-10-03) added directories to the name-hash there was only a single hash table in which both real cache entries and leading directory prefixes were registered. To distinguish between the two types of entries, directories were stored with a trailing '/'. 2092678c (name-hash.c: fix endless loop with core.ignorecase=true, 2013-02-28), however, moved directories to a separate hash table (index_state.dir_hash) but retained the (now) redundant trailing '/', thus callers continue to bear the burden of ensuring the slash's presence before searching the index for a directory. Eliminate this redundancy by storing paths in the dir-hash without the trailing '/'. An important benefit of this change is that it eliminates undocumented and dangerous behavior of dir.c:directory_exists_in_index_icase() in which it assumes not only that it can validly access one character beyond the end of its incoming directory argument, but also that that character will unconditionally be a '/'. This perilous behavior was "tolerated" because the string passed in by its lone caller always had a '/' in that position, however, things broke [1] when 2eac2a4c (ls-files -k: a directory only can be killed if the index has a non-directory, 2013-08-15) added a new caller which failed to respect the undocumented assumption.

2013-08-15ls-files -k: a directory only can be killed if the index has a non-directoryLibravatar Junio C Hamano1-2/+27
"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.

:(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.
