* [PATCH] Fix buffer overflow in ce_flush().Qingning Huo2005-09-11
| | | | | | | Add a check before appending SHA1 signature to write_buffer, flush it first if necessary. Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Improve handling of "." and ".." in git-diff-*Linus Torvalds2005-08-16
| | | | | | | | | | | | | This fixes up usage of ".." (without an ending slash) and "." (with or without the ending slash) in the git diff family. It also fixes pathspec matching for the case of an empty pathspec, since a "." in the top-level directory (or enough ".." under subdirectories) will result in an empty pathspec. We used to not match it against anything, but it should in fact match everything. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] mmap error handlingPavel Roskin2005-07-29
| | | | | | | | | | | | | | | | | | I have reviewed all occurrences of mmap() in git and fixed three types of errors/defects: 1) The result is not checked. 2) The file descriptor is closed if mmap() succeeds, but not when it fails. 3) Various casts applied to -1 are used instead of MAP_FAILED, which is specifically defined to check mmap() return value. [jc: This is a second round of Pavel's patch. He fixed up the problem that close() potentially clobbering the errno from mmap, which the first round had.] Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Make "ce_match_path()" a generic helper functionLinus Torvalds2005-07-14
| | | | | | ... and make git-diff-files use it too. This all _should_ make the diffcore-pathspec.c phase unnecessary, since the diff'ers now all do the path matching early interally.
* [PATCH] Fix oversimplified optimization for add_cache_entry().Junio C Hamano2005-06-25
| | | | | | | | | | | | | | | | | | An earlier change to optimize directory-file conflict check broke what "read-tree --emu23" expects. This is fixed by this commit. (1) Introduces an explicit flag to tell add_cache_entry() not to check for conflicts and use it when reading an existing tree into an empty stage --- by definition this case can never introduce such conflicts. (2) Makes read-cache.c:has_file_name() and read-cache.c:has_dir_name() aware of the cache stages, and flag conflict only with paths in the same stage.

* read-cache.c: remove stray debugging printfLinus Torvalds2005-06-18
| | | | | Pointed out by Junio, part of my debugging of the rewrite of the file/dir conflict handling.
* Re-implement "check_file_directory_conflict()"Linus Torvalds2005-06-18
| | | | | | | | | | | | This is (imho) more readable, and is also a lot faster. The expense of looking up sub-directory beginnings was killing us on things like "git-diff-cache", even though that one didn't even care at all about the file vs directory conflicts. We really only care when somebody tries to add a conflicting name to stage 0. We should go through the conflict rules more carefully some day.
* [PATCH] Bugfix: read-cache.c:write_cache() misrecords number of entries.Junio C Hamano2005-06-10
| | | | | | | | | | | When we choose to omit deleted entries, we should subtract numbers of such entries from the total number in the header. Signed-off-by: Junio C Hamano <junkio@cox.net> Oops. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* git-read-tree: remove deleted files in the working directoryLinus Torvalds2005-06-09
| | | | Only when "-u" is used of course.

* [PATCH] check_file_directory_conflict path fixDavid Meybohm2005-05-27
| | | | | | | | | | | | | | | | | | | check_file_directory_conflict can give the wrong answers. This is because the wrong length is passed to cache_name_pos. The length passed should be the length of the whole path from the root, not the length of each path subcomponent. $ git-init-db defaulting to local storage area $ mkdir path && touch path/file $ git-update-cache --add path/file $ rm path/file $ mkdir path/file && touch path/file/f $ git-update-cache --add path/file/f <-- Conflict ignored $ Signed-off-by: David Meybohm <dmeybohmlkml@bellsouth.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Don't care about st_dev in the index fileLinus Torvalds2005-05-22
| | | | | | | | | Thomas Glanzmann points out that it doesn't work well with different clients accessing the repository over NFS - they have different views on what the "device" for the filesystem is. Of course, other filesystems may not even have stable inode numbers. But we don't care. At least for now.
* Include file cleanups..Linus Torvalds2005-05-22
| | | | | | | Add <limits.h> to the include files handled by "cache.h", and remove extraneous #include directives from various .c files. The rule is that "cache.h" gets all the basic stuff, so that we'll have as few system dependencies as possible.
* Introduce "base_name_compare()" helper functionLinus Torvalds2005-05-20
| | | | | | This one compares two pathnames that may be partial basenames, not full paths. We need to get the path sorting right, since a directory name will sort as if it had the final '/' at the end.
* [PATCH] Implement git-checkout-cache -u to update stat information in the cache.Junio C Hamano2005-05-19
| | | | | | | | | | With -u flag, git-checkout-cache picks up the stat information from newly created file and updates the cache. This removes the need to run git-update-cache --refresh immediately after running git-checkout-cache. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Kill a bunch of pointer sign warnings for gcc4Brian Gerst2005-05-18

* A stylistic fix to read-cache.cJunio C Hamano2005-05-08
| | | | | | | Changes "if (pointer == 0)" to "if (!pointer)" to match the rest of the code, noticed by Petr Baudis. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Add git-update-cache --replace option.Junio C Hamano2005-05-07
| | | | | | | | | | | | When "path" exists as a file or a symlink in the index, an attempt to add "path/file" is refused because it results in file vs directory conflict. Similarly when "path/file1", "path/file2", etc. exist, an attempt to add "path" as a file or a symlink is refused. With git-update-cache --replace, these existing entries that conflict with the entry being added are automatically removed from the cache, with warning messages. Signed-off-by: Junio C Hamano <junkio@cox.net>
* git-update-cache refuses to add a file where a directory is registed.Junio C Hamano2005-05-07
| | | | | | | And vice versa. The next commit will introduce an option --replace to allow replacing existing entries. Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Do not initialize sha1_file_directory by hand.Junio C Hamano2005-05-06
| | | | | | | | | | Some commands initialize sha1_file_directory by hand. There is no need to do so; sha1_file.c knows how to handle it. The next patch will remove the variable altogether. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Revert bogus optimization that avoids index file writesLinus Torvalds2005-05-06
| | | | | | | | | | It didn't properly mark all cache updates as being dirty, and causes merge errors due to that. In particular, it didn't notice when a file was force-removed. Besides, it was ugly as hell. I've put in place a slightly cleaner version, but I've not enabled the optimization because I don't want to be burned again.
* [PATCH] fix compare symlink against readlink not dataKay Sievers2005-05-06
| | | | | | | | | | | | Fix update-cache to compare the blob of a symlink against the link-target and not the file it points to. Also ignore all permissions applied to links. Thanks to Greg for recognizing this while he added our list of symlinks back to the udev repository. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] git and symlinks as tracked contentKay Sievers2005-05-05
| | | | | | | | | | Allow to store and track symlink in the repository. A symlink is stored the same way as a regular file, only with the appropriate mode bits set. The symlink target is therefore stored in a blob object. This will hopefully make our udev repository fully functional. :) Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Allow writing to the private index file mapping.Linus Torvalds2005-04-26
| | | | | We now modify the in-memory copy of the index file in "diff-cache", so we need to add PROT_WRITE.
* [PATCH] introduce xmalloc and xreallocChristopher Li2005-04-26
| | | | | | | | Introduce xmalloc and xrealloc to die gracefully with a descriptive message when out of memory, rather than taking a SIGSEGV. Signed-off-by: Christopher Li<chrislgit@chrisli.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* New "diff-cache" implementation.Linus Torvalds2005-04-22
| | | | | | | | | | This one is about a million times simpler, and much more likely to be correct too. Instead of trying to match up a tree object against the index, we just read in the tree object side-by-side into the index, and just walk the resulting index file. This was what all the read-tree cleanups were all getting to.
* Add support for a "GIT_INDEX_FILE" environment variable.Linus Torvalds2005-04-21
| | | | | | | | | We use that to specify alternative index files, which can be useful if you want to (for example) generate a temporary index file to do some specific operation that you don't want to mess with your main one with. It defaults to the regular ".git/index" if it hasn't been specified.
* Fix NSEC compile problem, and properly parse the rev-tree cmd line.Linus Torvalds2005-04-21
| | | | The rev-tree thing just happened to work. It shouldn't have.
* Make the sha1 of the index file go at the very end of the file.Linus Torvalds2005-04-20
| | | | This allows us to both calculate it and verify it faster.
* Speed up index file writing by chunking it nicely.Linus Torvalds2005-04-20
| | | | | | No point in making 17,000 small writes when you can make just a couple of hundred nice 8kB writes instead and save a lot of time.
* Split up read-cache.c into more logical clumps.Linus Torvalds2005-04-18
| | | | | | | Do the usage and error reporting in "usage.c", and the sha1 file accesses in "sha1_file.c". Small, nice, easily separated parts. Good.
* [PATCH] fix bug in read-cache.c which loses files when merging a treeJames Bottomley2005-04-18
| | | | | | | | | I noticed this when I tried a non-trivial scsi merge and checked the results against BK. The problem is that remove_entry_at() actually decrements active_nr, so decrementing it in add_cache_entry() before calling remove_entry_at() is a double decrement (hence we lose cache entries at the end).
* [PATCH] Fix +x-related show-diff false positivesPetr Baudis2005-04-17
| | | | | | | | | | | | This fixes show-diff listing all +x files as differring. Signed-off-by: Petr Baudis <pasky@ucw.cz> [ That's what I get for working on a G5 - my testing was all big-endian in the first place. -- Linus ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] update-cache --remove marks the path merged.Junio C Hamano2005-04-17
| | | | | | | | | | | | | When update-cache --remove is run, resolve unmerged state for the path. This is consistent with the update-cache --add behaviour. Essentially, the user is telling us how he wants to resolve the merge by running update-cache. Signed-off-by: Junio C Hamano <junkio@cox.net> Fixed to do the right thing at the end. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Be much more liberal about the file mode bits.Linus Torvalds2005-04-16
| | | | | | We only really care about the difference between a file being executable or not (by its owner). Everything else we leave for the user umask to decide.
* When inserting a index entry of stage 0, remove all old unmerged entries.Linus Torvalds2005-04-16
| | | | This allows you to actually tell git that you've resolved a conflict.
* Make cache entry comparison take the new "state" flag into account.Linus Torvalds2005-04-15
| | | | | This is what allows us to have multiple states of the same file in the index, and what makes it always sort correctly.
* Convert the index file reading/writing to use network byte order.Linus Torvalds2005-04-15
| | | | | | | This allows using a git tree over NFS with different byte order, and makes it possible to just copy a fully populated repository and have the end result immediately usable (needing just a refresh to update the stat information).
* Fix read-cache.c collission check logic.Linus Torvalds2005-04-13
| | | | | | Not only did it test the #define the wrong way around, but it also leaked file descriptors and VM space. This should fix it.

* [PATCH] Consolidate the error handlingPetr Baudis2005-04-13
| | | | | | | Now there is error() for "library" errors and die() for fatal "application" errors. usage() is now used strictly only for usage errors. Signed-off-by: Petr Baudis <pasky@ucw.cz>
* [PATCH] Make nsec checking optionalPetr Baudis2005-04-13
| | | | | | | | | The nsec field of ctime/mtime is now checked only with -DNSEC defined during compilation. nsec acts broken since it is stored in the icache but apparently just gets to zero when flushed to filesystem not supporting it (e.g. ext3), creating illusions of false changes. At least that's my impression. Signed-off-by: Petr Baudis <pasky@ucw.cz>
* [PATCH] SHA1 naive collision checkingPetr Baudis2005-04-13
| | | | | | | | When compiled with -DCOLLISION_CHECK, we will check against SHA1 collisions when writing to the object database. From: Christopher Li <chrislgit@chrisli.org> Signed-off-by: Petr Baudis <pasky@ucw.cz>
* Rename ".dircache" directory to ".git"Linus Torvalds2005-04-11
| | | | I started out calling the tool "dircache". That's clearly moronic.
* Fix "usage()" to do the missing line termination.Linus Torvalds2005-04-11
| | | | It got broken when I changed it to use stdarg.
* Fix off-by-one error in removal of cache entry.Linus Torvalds2005-04-10
| | | | | | Also make the return value of "cache_name_pos()" be sane: positive or zero if we found it (it's the index into the cache array), and "-pos-1" to indicate where it should go if we didn't.
* Add "-R" flag to "diff-tree", so that it will recursively traverse a tree of ↵Linus Torvalds2005-04-10
| | | | | | | | trees as it diffs them. This makes diff-tree usable again in the new world order.
* Make "update-cache" a bit friendlier to use (and harder to mis-use).Linus Torvalds2005-04-10
| | | | | | | It now requires the "--add" flag before you add any new files, and a "--remove" file if you want to mark files for removal. And giving it the "--refresh" flag makes it just update all the files that it already knows about.
