2008-02-22Avoid unnecessary "if-before-free" tests.Jim Meyering
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: 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];a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <>.

* jc/gitignore-ends-with-slash: gitignore: lazily find dtype gitignore(5): Allow "foo/" in ignore list to match directory "foo"
2008-02-05gitignore: lazily find dtypeJunio C Hamano
When we process "foo/" entries in gitignore files on a system that does not have d_type member in "struct dirent", the earlier implementation ran lstat(2) separately when matching with entries that came from the command line, in-tree .gitignore files, and $GIT_DIR/info/excludes file. This optimizes it by delaying the lstat(2) call until it becomes absolutely necessary. The initial idea for this change was by Jeff King, but I optimized it further to pass pointers to around.

2008-02-05gitignore(5): Allow "foo/" in ignore list to match directory "foo"Junio C Hamano
A pattern "foo/" in the exclude list did not match directory "foo", but a pattern "foo" did. 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.

2008-01-23Create pathname-based hash-table lookup into indexLinus Torvalds
This creates a hash index of every single file added to the index. 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.

2008-01-21Make on-disk index representation separate from in-core oneLinus Torvalds
This converts the index explicitly on read and write to its on-disk format, allowing the in-core format to contain more flags, and be simpler. In particular, the in-core format is now host-endian (as opposed to the on-disk one that is network endian in order to be able to be shared across machines) and as a result we can dispense with all the htonl/ntohl on accesses to the cache_entry fields. This will make it easier to make use of various temporary flags that do not exist in the on-disk format. Signed-off-by: Linus Torvalds <>

2007-11-29per-directory-exclude: lazily read .gitignore filesJunio C Hamano
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.

2007-11-16Fix per-directory exclude handing for "git add"Junio C Hamano
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 <>
2007-11-14core.excludesfile clean-upJunio C Hamano
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(). Signed-off-by: Junio C Hamano <>

2007-10-21Fix directory scanner to correctly ignore files without d_typeLinus Torvalds
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 <>

2007-06-13builtin-add: simplify (and increase accuracy of) exclude handlingJeff King
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. Signed-off-by: Jeff King <> Signed-off-by: Jonas Fonseca <> Signed-off-by: Junio C Hamano <>

2007-04-23dir.c(common_prefix): Fix two bugsJohannes Schindelin
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.

2007-04-12Teach directory traversal about subprojectsLinus Torvalds
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).

2007-04-01Optimize directory listing with pathspec limiter.Linus Torvalds
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_tShawn O. Pearce
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().

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. Signed-off-by: Junio C Hamano <>

I'll use it for builtin-rm.c too. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
2006-05-17Clean up git-ls-file directory walking library interfaceLinus Torvalds
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).

2006-05-17libify git-ls-files directory traversalLinus Torvalds
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. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
