* git-add: no need for -f when resolving a conflict in already tracked pathJeff King2009-05-31
| | | | | | | | | | | | | | | | | | | | | | | | When a path F that matches ignore pattern has a conflict, "git add F" insisted the -f option be given, which did not make sense. It would have required -f when the path was originally added, but when resolving a conflict, it already is tracked. So this should work (and does): $ echo file >.gitignore $ echo content >file $ git add -f file ;# need -f because we are adding new path $ echo more content >>file $ git add file ;# don't need -f; it is not actually an "other" file This is handled under the hood by the COLLECT_IGNORED option to read_directory. When that code finds an ignored file, it checks the index to make sure it is not actually a tracked file. However, the test it uses does not take into account unmerged entries, and considers them to still be ignored. "git ls-files" uses a more elaborate test and gets the right answer and the same test should be used here. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* dir.c: clean up handling of 'path' parameter in read_directory_recursive()Linus Torvalds2009-05-16
| | | | | | | | | | | | | | | | | | | | | | | | Right now we pass two different pathnames ('path' and 'base') down to read_directory_recursive(), and the only real reason for that is that we want to allow an empty 'base' parameter, but when we do so, we need the pathname to "opendir()" to be "." rather than the empty string. And rather than handle that confusion in the caller, we can just fix read_directory_recursive() to handle the case of an empty path itself, by just passing opendir() a "." ourselves if the path is empty. This would allow us to then drop one of the pathnames entirely from the calling convention, but rather than do that, we'll start separating them out as a "filesystem pathname" (the one we use for filesystem accesses) and a "git internal base name" (which is the name that we use for git internally). That will eventually allow us to do things like handle different encodings (eg the filesystem pathnames might be Latin1, while git itself would use UTF-8 for filename information).

The reason? The argument list is actually something different from what you think it is. For git, it's a "pathspec", so what actualy happens is that in *both* cases, it will really traverse the whole tree, and then match every file it finds against the pathspec. So think of the arguments not as a file list, but as a random bunch of patterns to match against the files you have! Which is why the cost is actually approximately O(n*m), where "n" is the size of the working tree, and "m" is the number of pathspecs. So the reason "git add ." is fast is actually that "m" in that case is just 1 (just one trivial pattern), and then "git add *" is slow because "m" is large (lots of complicated patterns). In both cases, 'n' is the same (== the whole set of files in your working tree). Anyway, here's a trivial patch that doesn't change this fundamental fact, but that avoids doing anything *expensive* until we've done some cheap initial tests. It may or may not help your test-case, but it's pretty simple and it matches the other git optimizations in this area (ie "conceptually handle the general case, but optimize the simple cases where we can exit early") Notice how this patch doesn' actually change the fundamental O(n^2) behaviour, but it makes it much cheaper by generally avoiding the expensive 'fnmatch' and 'strlen/strncmp' when they are obviously not needed.

Additionaly match_one() was modified to allow a name[] that is not NUL terminated. This allows us to check if the name matched the pathspec exactly instead of recursively.

* Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

This attempts to extend the exclude mechanism so that it would while not matching a regular file or a symbolic link "foo". In order to differentiate a directory and non directory, this passes down the type of path being checked to excluded() function. A downside is that the recursive directory walk may need to run lstat(2) more often on systems whose "struct dirent" do not give the type of the entry; earlier it did not have to do so for an excluded path, but we now need to figure out if a path is a directory before deciding to exclude it. This is especially bad because an idea similar to the earlier CE_UPTODATE optimization to reduce number of lstat(2) calls would by definition not apply to the codepaths involved, as (1) directories will not be registered in the index, and (2) excluded paths will not be in the index anyway.

* | Create pathname-based hash-table lookup into indexLinus Torvalds2008-01-22

Right now that hash index isn't actually used for much: I implemented a "cache_name_exists()" function that uses it to efficiently look up a filename in the index without having to do the O(logn) binary search, but quite frankly, that's not why this patch is interesting. No, the whole and only reason to create the hash of the filenames in the index is that by modifying the hash function, you can fairly easily do things like making it always hash equivalent names into the same bucket. That, in turn, means that suddenly questions like "does this name exist in the index under an _equivalent_ name?" becomes much much cheaper. Guiding principles behind this patch: - it shouldn't be too costly. In fact, my primary goal here was to actually speed up "git commit" with a fully populated kernel tree, by being faster at checking whether a file already existed in the index. I did succeed, but only barely: Best before: [torvalds@woody linux]$ time git commit > /dev/null real 0m0.255s user 0m0.168s sys 0m0.088s Best after: [torvalds@woody linux]$ time ~/git/git commit > /dev/null real 0m0.233s user 0m0.144s sys 0m0.088s so some things are actually faster (~8%). Caveat: that's really the best case. Other things are invariably going to be slightly slower, since we populate that index cache, and quite frankly, few things really use it to look things up. That said, the cost is really quite small. The worst case is probably doing a "git ls-files", which will do very little except puopulate the index, and never actually looks anything up in it, just lists it. Before: [torvalds@woody linux]$ time git ls-files > /dev/null real 0m0.016s user 0m0.016s sys 0m0.000s After: [torvalds@woody linux]$ time ~/git/git ls-files > /dev/null real 0m0.021s user 0m0.012s sys 0m0.008s and while the thing has really gotten relatively much slower, we're still talking about something almost unmeasurable (eg 5ms). And that really should be pretty much the worst case. So we lose 5ms on one "benchmark", but win 22ms on another. Pick your poison - this patch has the advantage that it will _likely_ speed up the cases that are complex and expensive more than it slows down the cases that are already so fast that nobody cares. But if you look at relative speedups/slowdowns, it doesn't look so good. - It should be simple and clean The code may be a bit subtle (the reasons I do hash removal the way I do etc), but it re-uses the existing hash.c files, so it really is fairly small and straightforward apart from a few odd details. Now, this patch on its own doesn't really do much, but I think it's worth looking at, if only because if done correctly, the name hashing really can make an improvement to the whole issue of "do we have a filename that looks like this in the index already". And at least it gets real testing by being used even by default (ie there is a real use-case for it even without any insane filesystems). NOTE NOTE NOTE! The current hash is a joke. I'm ashamed of it, I'm just not ashamed of it enough to really care. I took all the numbers out of my nether regions - I'm sure it's good enough that it works in practice, but the whole point was that you can make a really much fancier hash that hashes characters not directly, but by their upper-case value or something like that, and thus you get a case-insensitive hash, while still keeping the name and the index itself totally case sensitive.

| * file_exists(): dangling symlinks do existJunio C Hamano2007-11-22
| | | | | | | | | | | | | | | | | | This function is used to see if a path given by the user does exist on the filesystem. A symbolic link that does not point anywhere does exist but running stat() on it would yield an error, and it incorrectly said it does not exist. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | per-directory-exclude: lazily read .gitignore filesJunio C Hamano2007-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Operations that walk directories or trees, which potentially need to consult the .gitignore files, used to always try to open the .gitignore file every time they entered a new directory, even when they ended up not needing to call excluded() function to see if a path in the directory is ignored. This was done by push/pop exclude_per_directory() functions that managed the data in a stack. This changes the directory walking API to remove the need to call these two functions. Instead, the directory walk data structure caches the data used by excluded() function the last time, and lazily reuses it as much as possible. Among the data the last check used, the ones from deeper directories that the path we are checking is outside are discarded, data from the common leading directories are reused, and then the directories between the common directory and the directory the path being checked is in are checked for .gitignore file. This is very similar to the way gitattributes are handled. This API change also fixes "ls-files -c -i", which called excluded() without setting up the gitignore data via the old push/pop functions.

* Fix per-directory exclude handing for "git add"Junio C Hamano2007-11-16
| | | | | | | | | | | | | | | | | | | In "dir_struct", each exclusion element in the exclusion stack records a base string (pointer to the beginning with length) so that we can tell where it came from, but this pointer is just pointing at the parameter that is given by the caller to the push_exclude_per_directory() function. While read_directory_recursive() runs, calls to excluded() makes use the data in the exclusion elements, including this base string. The caller of read_directory_recursive() is not supposed to free the buffer it gave to push_exclude_per_directory() earlier, until it returns. The test case Bruce Stephens gave in the mailing list discussion was simplified and added to the t3700 test. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* core.excludesfile clean-upJunio C Hamano2007-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are inconsistencies in the way commands currently handle the core.excludesfile configuration variable. The problem is the variable is too new to be noticed by anything other than git-add and git-status. * git-ls-files does not notice any of the "ignore" files by default, as it predates the standardized set of ignore files. The calling scripts established the convention to use .git/info/exclude, .gitignore, and later core.excludesfile. * git-add and git-status know about it because they call add_excludes_from_file() directly with their own notion of which standard set of ignore files to use. This is just a stupid duplication of code that need to be updated every time the definition of the standard set of ignore files is changed. * git-read-tree takes --exclude-per-directory=<gitignore>, not because the flexibility was needed. Again, this was because the option predates the standardization of the ignore files. * git-merge-recursive uses hardcoded per-directory .gitignore and nothing else. git-clean (scripted version) does not honor core.* because its call to underlying ls-files does not know about it. git-clean in C (parked in 'pu') doesn't either. We probably could change git-ls-files to use the standard set when no excludes are specified on the command line and ignore processing was asked, or something like that, but that will be a change in semantics and might break people's scripts in a subtle way. I am somewhat reluctant to make such a change. On the other hand, I think it makes perfect sense to fix git-read-tree, git-merge-recursive and git-clean to follow the same rule as other commands. I do not think of a valid use case to give an exclude-per-directory that is nonstandard to read-tree command, outside a "negative" test in the t1004 test script. This patch is the first step to untangle this mess. The next step would be to teach read-tree, merge-recursive and clean (in C) to use setup_standard_excludes().

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>
