Jeff King	25fd2f7a31	Fix ALLOC_GROW calls with obsolete semantics ALLOC_GROW now expects the 'nr' argument to be "how much you want" and not "how much you have". This fixes all cases where we weren't previously adding anything to the 'nr'. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	18 years ago
Jeff King	e96980ef81	builtin-add: simplify (and increase accuracy of) exclude handling 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.

Jeff King	2abd31b078	dir_struct: add collect_ignored option 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.

Jeff King	6815e56933	refactor dir_add_name 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>	18 years ago
Martin Waitz	302b9282c9	rename dirlink to gitlink. Unify naming of plumbing dirlink/gitlink concept: git ls-files -z '*.[ch]' \| xargs -0 perl -pi -e 's/dirlink/gitlink/g;' -e 's/DIRLNK/GITLINK/g;' Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Michael Spang	b991625611	dir.c: Omit non-excluded directories with dir->show_ignored This makes "git-ls-files --others --directory --ignored" behave as documented and consequently also fixes "git-clean -d -X". Previously, git-clean would remove non-excluded directories even when using the -X option.

Johannes Schindelin	c7f34c180b	dir.c(common_prefix): Fix two bugs 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.

Linus Torvalds	ab22aed3b7	Don't show gitlink directories when we want "other" files 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>	18 years ago
Linus Torvalds	095952585c	Teach directory traversal about subprojects 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).

Linus Torvalds	5d5cea67af	Avoid overflowing name buffer in deep directory structures This just makes sure that when we do a read_directory(), we check that the filename fits in the buffer we allocated (with a bit of slop) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Linus Torvalds	9fc42d6091	Optimize directory listing with pathspec limiter. 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.

Shawn O. Pearce	dc49cd769b	Cast 64 bit off_t to 32 bit size_t 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.

Andy Whitcroft	93d26e4cb9	short i/o: fix calls to read to use xread or read_in_full 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().

Junio C Hamano	4d06f8ac43	Fix 'git add' with .gitignore 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.

Junio C Hamano	e813d50e35	match_pathspec() -- return how well the spec matched 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>	18 years ago
Junio C Hamano	85023577a8	simplify inclusion of system header files. 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>	18 years ago
Junio C Hamano	f8a9d42872	read-tree: further loosen "working file will be lost" check. 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).

Pavel Roskin	a9486b02ec	Avoid C99 comments, use old-style C comments instead. 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. "gcc -std=c89 -pedantic" can flag many incompatible constructs as warnings, but C99 comments will cause it to emit an error.

Linus Torvalds	b4189aa848	Clean up git-ls-file directory walking library interface This moves the code to add the per-directory ignore files for the base directory into the library routine. That not only allows us to turn the function push_exclude_per_directory() static again, it also simplifies the library interface a lot (the caller no longer needs to worry about any of the per-directory exclude files at all).

Linus Torvalds	453ec4bdf4	libify git-ls-files directory traversal 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. The index matching and pathspec prefix calculation is still in ls-files.c, but this is a big part of it.
