2009-12-14ie_match_stat(): do not ignore skip-worktree bit with CE_MATCH_IGNORE_VALIDNguyễn Thái Ngọc Duy
Previously CE_MATCH_IGNORE_VALID flag is used by both valid and skip-worktree bits. While the two bits have similar behaviour, sharing this flag means "git update-index --really-refresh" will ignore skip-worktree while it should not. Instead another flag is introduced to ignore skip-worktree bit, CE_MATCH_IGNORE_VALID only applies to valid bit. Signed-off-by: Nguyễn Thái Ngọc Duy <> Signed-off-by: Junio C Hamano <>
2009-08-18check_path(): allow symlinked directories to checkout-index --prefixJunio C Hamano
Merlyn noticed that Documentation/ no longer correctly removes old installed documents when the target directory has a leading path that is a symlink. It turns out that "checkout-index --prefix" was broken by recent b6986d8 (git-checkout: be careful about untracked symlinks, 2009-07-29). I suspect has_symlink_leading_path() could learn the third parameter (prefix that is allowed to be symlinked directories) to allow us to retire a similar function has_dirs_only_path(). Another avenue of fixing this I considered was to get rid of base_dir and base_dir_len from "struct checkout", and instead make "git checkout-index" when run with --prefix mkdir the leading path and chdir in there. It might be the best longer term solution to this issue, as the base_dir feature is used only by that rather obscure codepath as far as I know. But at least this patch should fix this breakage.

This helps to notice when something's going wrong, especially on systems which lock open files. I used the following criteria when selecting the code for replacement: - it was already printing a warning for the unlink failures - it is in a function which already printing something or is called from such a function - it is in a static function, returning void and the function is only called from a builtin main function (cmd_) - it is in a function which handles emergency exit (signal handlers) - it is in a function which is obvously cleaning up the lockfiles Signed-off-by: Alex Riesen <> Signed-off-by: Junio C Hamano <>
2009-04-20Windows: Skip fstat/lstat optimization in write_entry()Johannes Sixt
Commit e4c72923 (write_entry(): use fstat() instead of lstat() when file is open, 2009-02-09) introduced an optimization of write_entry(). Unfortunately, we cannot take advantage of this optimization on Windows because there is no guarantee that the time stamps are updated before the file is closed: "The only guarantee about a file timestamp is that the file time is correctly reflected when the handle that makes the change is closed." ( The failure of this optimization on Windows can be observed most easily by running a 'git checkout' that has to update several large files. In this case, 'git checkout' will report modified files, but infact only the timestamps were incorrectly recorded in the index, as can be verified by a subsequent 'git diff', which shows no change. Dmitry Potapov reports the same fix needs on Cygwin; this commit contains his updates for that. Signed-off-by: Johannes Sixt <> Signed-off-by: Junio C Hamano <>
2009-02-10write_entry(): use fstat() instead of lstat() when file is openKjetil Barvik
Currently inside write_entry() we do an lstat(path, &st) call on a file which have just been opened inside the exact same function.

2009-01-18lstat_cache(): introduce has_dirs_only_path() functionKjetil Barvik
The create_directories() function in entry.c currently calls stat() or lstat() for each path component of the pathname 'path' each and every time. For the 'git checkout' command, this function is called on each file for which we must do an update (ce->ce_flags & CE_UPDATE), so we get lots and lots of calls. To fix this, we make a new wrapper to the lstat_cache() function, and call the wrapper function instead of the calls to the stat() or the lstat() functions. Since the paths given to the create_directories() function, is sorted alphabetically, the new wrapper would be very cache effective in this situation. To support it we must update the lstat_cache() function to be able to say that "please test the complete length of 'name'", and also to give it the length of a prefix, where the cache should use the stat() function instead of the lstat() function to test each path component.

2008-03-19Fix possible Solaris problem in 'checkout_entry()'Linus Torvalds
Currently when checking out an entry "path", we try to unlink(2) it first (because there could be stale file), and if there is a directory there, try to deal with it (typically we run recursive rmdir). We ignore the error return from this unlink because there may not even be any file there. However if you are root on Solaris, you can unlink(2) a directory successfully and corrupt your filesystem. This moves the code around and check the directory first, and then unlink(2). Also we check the error code from it. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
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 <>

2007-09-29strbuf change: be sure ->buf is never ever NULL.Pierre Habouzit
For that purpose, the ->buf is always initialized with a char * buf living in the strbuf module. It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

2007-09-17Rewrite convert_to_{git,working_tree} to use strbuf's.Pierre Habouzit
* Now, those functions take an "out" strbuf argument, where they store their result if any. In that case, it also returns 1, else it returns 0. * those functions support "in place" editing, in the sense that it's OK to call them this way: convert_to_git(path, sb->buf, sb->len, sb); When doable, conversions are done in place for real, else the strbuf content is just replaced with the new one, transparentely for the caller. If you want to create a new filter working this way, being the accumulation of filter1, filter2, ... filtern, then your meta_filter would be: int meta_filter(..., const char *src, size_t len, struct strbuf *sb) { int ret = 0; ret |= filter1(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } ret |= filter2(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } .... return ret | filtern(..., src, len, sb); } That's why subfilters the convert_to_* functions called were also rewritten to work this way.

This makes .gitattributes files to be read from the index when they are not checked out to the work tree. This is in line with the way we always allowed low-level tools to operate in sparsely checked out work tree in a reasonable way. It swaps the order of new file creation and converting the blob to work tree representation; otherwise when we are in the middle of checking out .gitattributes we would notice an empty but unwritten .gitattributes file in the work tree and will ignore the copy in the index.

2007-07-18Do not expect unlink(2) to fail on a directory.Junio C Hamano
When "git checkout-index" checks out path A/B/C, it makes sure A and A/B are truly directories; if there is a regular file or symlink at A, we prefer to remove it. We used to do this by catching an error return from mkdir(2), and on EEXIST did unlink(2), and when it succeeded, tried another mkdir(2). Thomas Glanzmann found out the above does not work on Solaris for a root user, as unlink(2) was so old fashioned there that it allowed to unlink a directory. As pointed out, this still doesn't guarantee that git won't call "unlink()" on a directory (race conditions etc), but that's fundamentally true (there is no "funlink()" like there is "fstat()"), and besides, that is in no way git-specific (ie it's true of any application that gets run as root).

2007-03-03Add core.symlinks to mark filesystems that do not support symbolic links.Johannes Sixt
Some file systems that can host git repositories and their working copies do not support symbolic links. But then if the repository contains a symbolic link, it is impossible to check out the working copy. This patch enables partial support of symbolic links so that it is possible to check out a working copy on such a file system. A new flag core.symlinks (which is true by default) can be set to false to indicate that the filesystem does not support symbolic links. In this case, symbolic links that exist in the trees are checked out as small plain files, and checking in modifications of these files preserve the symlink property in the database (as long as an entry exists in the index). Of course, this does not magically make symbolic links work on such defective file systems; hence, this solution does not help if the working copy relies on that an entry is a real symbolic link.

2007-02-27convert object type handling from a string to a numberNicolas Pitre
We currently have two parallel notation for dealing with object types in the code: a string and a numerical value.

2007-02-14Lazy man's auto-CRLFLinus Torvalds
It currently does NOT know about file attributes, so it does its conversion purely based on content. Maybe that is more in the "git philosophy" anyway, since content is king, but I think we should try to do the file attributes to turn it off on demand. Anyway, BY DEFAULT it is off regardless, because it requires a [core] AutoCRLF = true in your config file to be enabled. We could make that the default for Windows, of course, the same way we do some other things (filemode etc). But you can actually enable it on UNIX, and it will cause: - "git update-index" will write blobs without CRLF - "git diff" will diff working tree files without CRLF - "git checkout" will write files to the working tree _with_ CRLF and things work fine. Funnily, it actually shows an odd file in git itself: git clone -n git test-crlf cd test-crlf git config core.autocrlf true git checkout git diff shows a diff for "Documentation/docbook-xsl.css". Why? Because we have actually checked in that file *with* CRLF! So when "core.autocrlf" is true, we'll always generate a *different* hash for it in the index, because the index hash will be for the content _without_ CRLF. Is this complete? I dunno. It seems to work for me. It doesn't use the filename at all right now, and that's probably a deficiency (we could certainly make the "is_binary()" heuristics also take standard filename heuristics into account). I don't pass in the filename at all for the "index_fd()" case (git-update-index), so that would need to be passed around, but this actually works fine. NOTE NOTE NOTE! The "is_binary()" heuristics are totally made-up by yours truly. I will not guarantee that they work at all reasonable. Caveat emptor. But it _is_ simple, and it _is_ safe, since it's all off by default. The patch is pretty simple - the biggest part is the new "convert.c" file, but even that is really just basic stuff that anybody can write in "Teaching C 101" as a final project for their first class in programming. Not to say that it's bug-free, of course - but at least we're not talking about rocket surgery here. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
2007-02-13Mark places that need blob munging later for CRLF conversion.Linus Torvalds
Here's a patch that I think we can merge right now. There may be other places that need this, but this at least points out the three places that read/write working tree files for git update-index, checkout and diff respectively. That should cover a lot of it [jc: git-apply uses an entirely different codepath both for reading and writing]. Some day we can actually implement it. In the meantime, this points out a place for people to start. We *can* even start with a really simple "we do CRLF conversion automatically, regardless of filename" kind of approach, that just look at the data (all three cases have the _full_ file data already in memory) and says "ok, this is text, so let's convert to/from DOS format directly". THAT somebody can write in ten minutes, and it would already make git much nicer on a DOS/Windows platform, I suspect. And it would be totally zero-cost if you just make it a config option (but please make it dynamic with the _default_ just being 0/1 depending on whether it's UNIX/Windows, just so that UNIX people can _test_ it easily).

2006-02-09"Assume unchanged" gitJunio C Hamano
This adds "assume unchanged" logic, started by this message in the list discussion recently: <> This is a workaround for filesystems that do not have lstat() that is quick enough for the index mechanism to take advantage of. On the paths marked as "assumed to be unchanged", the user needs to explicitly use update-index to register the object name to be in the next commit. You can use two new options to update-index to set and reset the CE_VALID bit: git-update-index --assume-unchanged path... git-update-index --no-assume-unchanged path... These forms manipulate only the CE_VALID bit; it does not change the object name recorded in the index file. Nor they add a new entry to the index. When the configuration variable "core.ignorestat = true" is set, the index entries are marked with CE_VALID bit automatically after: - update-index to explicitly register the current object name to the index file. - when update-index --refresh finds the path to be up-to-date. - when tools like read-tree -u and apply --index update the working tree file and register the current object name to the index file. The flag is dropped upon read-tree that does not check out the index entry. This happens regardless of the core.ignorestat settings. Index entries marked with CE_VALID bit are assumed to be unchanged most of the time. However, there are cases that CE_VALID bit is ignored for the sake of safety and usability: - while "git-read-tree -m" or git-apply need to make sure that the paths involved in the merge do not have local modifications. This sacrifices performance for safety. - when git-checkout-index -f -q -u -a tries to see if it needs to checkout the paths. Otherwise you can never check anything out ;-). - when git-update-index --really-refresh (a new flag) tries to see if the index entry is up to date. You can start with everything marked as CE_VALID and run this once to drop CE_VALID bit for paths that are modified. Most notably, "update-index --refresh" honours CE_VALID and does not actively stat, so after you modified a file in the working tree, update-index --refresh would not notice until you tell the index about it with "git-update-index path" or "git-update-index --no-assume-unchanged path". This version is not expected to be perfect. I think diff between index and/or tree and working files may need some adjustment, and there probably needs other cases we should automatically unmark paths that are marked to be CE_VALID. But the basics seem to work, and ready to be tested by people who asked for this feature. Signed-off-by: Junio C Hamano <>

As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

2005-07-14Fix replacing of a directory with a file/symlink in git-checkout-cacheLinus Torvalds
The symlink case had never worked, and the file case was broken by the O_EXCL change because the error return changed from EISDIR to EEXIST. Fix both problems by just moving the test for an existing directory to a more logical place.
