2007-10-29Speedup scanning for excluded files.Libravatar Lars Knoll1-16/+43
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.

2007-10-21Fix directory scanner to correctly ignore files without d_typeLibravatar Linus Torvalds1-14/+38
On Fri, 19 Oct 2007, Todd T. Fries wrote: > If DT_UNKNOWN exists, then we have to do a stat() of some form to > find out the right type. That happened in the case of a pathname that was ignored, and we did not ask for "dir->show_ignored". That test used to be *together* with the "DTYPE(de) != DT_DIR", but splitting the two tests up means that we can do that (common) test before we even bother to calculate the real dtype. Of course, that optimization only matters for systems that don't have, or don't fill in DTYPE properly. I also clarified the real relationship between "exclude" and "dir->show_ignored". It used to do if (exclude != dir->show_ignored) { .. which wasn't exactly obvious, because it triggers for two different cases: - the path is marked excluded, but we are not interested in ignored files: ignore it - the path is *not* excluded, but we *are* interested in ignored files: ignore it unless it's a directory, in which case we might have ignored files inside the directory and need to recurse into it). so this splits them into those two cases, since the first case doesn't even care about the type. I also made a the DT_UNKNOWN case a separate helper function, and added some commentary to the cases. Linus Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-30Introduce remove_dir_recursively()Libravatar Johannes Schindelin1-0/+41
There was a function called remove_empty_dir_recursive() buried in refs.c. Expose a slightly enhanced version in dir.h: it can now optionally remove a non-empty directory. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-08-01get_relative_cwd(): clarify why it handles dir == NULLLibravatar Johannes Schindelin1-5/+10

2007-08-01Add functions get_relative_cwd() and is_inside_dir()Libravatar Johannes Schindelin1-0/+38
The function get_relative_cwd() works just as getcwd(), only that it takes an absolute path as additional parameter, returning the prefix of the current working directory relative to the given path. If the cwd is no subdirectory of the given path, it returns NULL. is_inside_dir() is just a trivial wrapper over get_relative_cwd().

2007-06-16Fix ALLOC_GROW calls with obsolete semanticsLibravatar Jeff King1-2/+2

2007-06-13builtin-add: simplify (and increase accuracy of) exclude handlingLibravatar Jeff King1-2/+14
Previously, the code would always set up the excludes, and then manually pick through the pathspec we were given, assuming that non-added but existing paths were just ignored. This was mostly correct, but would erroneously mark a totally empty directory as 'ignored'. Instead, we now use the collect_ignored option of dir_struct, which unambiguously tells us whether a path was ignored. This simplifies the code, and means empty directories are now just not mentioned at all. Furthermore, we now conditionally ask dir_struct to respect excludes, depending on whether the '-f' flag has been set. This means we don't have to pick through the result, checking for an 'ignored' flag; ignored entries were either added or not in the first place. We can safely get rid of the special 'ignored' flags to dir_entry, which were not used anywhere else.

2007-06-13dir_struct: add collect_ignored optionLibravatar Jeff King1-0/+12
When set, this option will cause read_directory to keep track of which entries were ignored. While this shouldn't effect functionality in most cases, it can make warning messages to the user much more useful. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-12refactor dir_add_nameLibravatar Jeff King1-11/+10
This is in preparation for keeping two entry lists in the dir object. This patch adds and uses the ALLOC_GROW() macro, which implements the commonly used idiom of growing a dynamic array using the alloc_nr function (not just in dir.c, but everywhere). We also move creation of a dir_entry to dir_entry_new. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-04-23dir.c(common_prefix): Fix two bugsLibravatar Johannes Schindelin1-1/+2
The function common_prefix() is used to find the common subdirectory of a couple of pathnames. When checking if the next pathname matches up with the prefix, it incorrectly checked the whole path, not just the prefix (including the slash). Thus, the expensive part of the loop was executed always. The other bug is more serious: if the first and the last pathname in the list have a longer common prefix than the common prefix for _all_ pathnames in the list, the longer one would be chosen. This bug was probably hidden by the fact that bash's wildcard expansion sorts the results, and the code just so happens to work with sorted input.

2007-04-12Don't show gitlink directories when we want "other" filesLibravatar Linus Torvalds1-0/+2
When "show_other_directories" is set, that implies that we are looking for untracked files, which obviously means that we should ignore directories that are marked as gitlinks in the index. This fixes "git status" in a superproject, that would otherwise always report that subprojects were "Untracked files:" Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-11Teach directory traversal about subprojectsLibravatar Linus Torvalds1-18/+115
This is the promised cleaned-up version of teaching directory traversal (ie the "read_directory()" logic) about subprojects. That makes "git add" understand to add/update subprojects. It now knows to look at the index file to see if a directory is marked as a subproject, and use that as information as whether it should be recursed into or not. It also generally cleans up the handling of directory entries when traversing the working tree, by splitting up the decision-making process into small functions of their own, and adding a fair number of comments. Finally, it teaches "add_file_to_cache()" that directory names can have slashes at the end, since the directory traversal adds them to make the difference between a file and a directory clear (it always did that, but my previous too-ugly-to-apply subproject patch had a totally different path for subproject directories and avoided the slash for that case).

2007-03-31Optimize directory listing with pathspec limiter.Libravatar Linus Torvalds1-5/+91
The way things are set up, you can now pass a "pathspec" to the "read_directory()" function. If you pass NULL, it acts exactly like it used to do (read everything). If you pass a non-NULL pointer, it will simplify it into a "these are the prefixes without any special characters", and stop any readdir() early if the path in question doesn't match any of the prefixes. NOTE! This does *not* obviate the need for the caller to do the *exact* pathspec match later. It's a first-level filter on "read_directory()", but it does not do the full pathspec thing. Maybe it should. But in the meantime, builtin-add.c really does need to do first read_directory(dir, .., pathspec); if (pathspec) prune_directory(dir, pathspec, baselen); ie the "prune_directory()" part will do the *exact* pathspec pruning, while the "read_directory()" will use the pathspec just to do some quick high-level pruning of the directories it will recurse into.

2007-03-07Cast 64 bit off_t to 32 bit size_tLibravatar Shawn O. Pearce1-2/+2
Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: Shawn O.

2007-01-08short i/o: fix calls to read to use xread or read_in_fullLibravatar Andy Whitcroft1-1/+1
We have a number of badly checked read() calls. Often we are expecting read() to read exactly the size we requested or fail, this fails to handle interrupts or short reads. Add a read_in_full() providing those semantics. Otherwise we at a minimum need to check for EINTR and EAGAIN, where this is appropriate use xread().

2006-12-29Fix 'git add' with .gitignoreLibravatar Junio C Hamano1-3/+5
When '*.ig' is ignored, and you have two files f.ig and d.ig/foo in the working tree, $ git add . correctly ignored f.ig but failed to ignore d.ig/foo. This was caused by a thinko in an earlier commit 4888c534, when we tried to allow adding otherwise ignored files. After reverting that commit, this takes a much simpler approach. When we have an unmatched pathspec that talks about an existing pathname, we know it is an ignored path the user tried to add, so we include it in the set of paths directory walker returned. This does not let you say "git add -f D" on an ignored directory D and add everything under D. People can submit a patch to further allow it if they want to, but I think it is a saner behaviour to require explicit paths to be spelled out in such a case.

2006-12-25match_pathspec() -- return how well the spec matchedLibravatar Junio C Hamano1-16/+35
This updates the return value from match_pathspec() so that the caller can tell cases between exact match, leading pathname match (i.e. file "foo/bar" matches a pathspec "foo"), or filename glob match. This can be used to prevent "rm dir" from removing "dir/file" without explicitly asking for recursive behaviour with -r flag, for example. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-20simplify inclusion of system header files.Libravatar Junio C Hamano1-3/+0
This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>

This follows up commit ed93b449 where we removed overcautious "working file will be lost" check. A new option "--exclude-per-directory=.gitignore" can be used to tell the "git-read-tree" command that the user does not mind losing contents in untracked files in the working tree, if they need to be overwritten by a merge (either a two-way "switch branches" merge, or a three-way merge).

This creates a new git-runstatus which should do roughly the same thing as the run_status function from git-commit.sh.

This doesn't make the code uglier or harder to read, yet it makes the code more portable. This also simplifies checking for other potential incompatibilities.

This moves the code to add the per-directory ignore files for the base directory into the library routine.

This moves the core directory traversal and filename exclusion logic into the general git library, making it available for other users directly. If we ever want to do "git commit" or "git add" as a built-in (and we do), we want to be able to handle most of git-ls-files as a library. NOTE! Not all of git-ls-files is libified by this.
