Junio C Hamano	383f85b72a	Free compressed buffer after write_sha1_file() is done. This does not matter for commands that write just a handful SHA1 files, but is noticeable in git-convert-cache which essentially traverses the entire object database. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Junio C Hamano	ace1534d6f	Introduce SHA1_FILE_DIRECTORIES to support multiple object databases. SHA1_FILE_DIRECTORIES environment variable is a colon separated paths used when looking for SHA1 files not found in the usual place for reading. Creating a new SHA1 file does not use this alternate object database location mechanism. This is useful to archive older, rarely used objects into separate directories.

Junio C Hamano	bf60144c0a	[PATCH] Remove unused sha1_file_directory variable. Now all the users have gone. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Linus Torvalds	a31c6d022e	sha1_file: make the new sha1 object writing be coda-friendly. Coda doesn't like cross-directory hardlinks. So try to fall back on a plain rename instead.	20 years ago
Linus Torvalds	aac1794132	Improve sha1 object file writing. Make it much safer: we write to a temporary file, and then link that temporary file to the final destination. This avoids all the nasty races if several people write the same object at the same time. It should also result in nicer on-disk layout, since it means that objects all get created in the same subdirectory. That makes a lot of block allocation algorithms happier, since the objects will now be allocated from the same zone.	20 years ago
Junio C Hamano	74400e7175	Add git-write-blob. A new command, git-write-blob, is introduced. This registers the contents of any file on the filesystem as a blob in the object database and reports its SHA1 to the standard output. To implement it, the patch promotes index_fd() from a static function in update-cache.c to extern and moves it to a library source, sha1_file.c. This command is used to update git-merge-one-file-script so that it does not smudge the work tree. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Linus Torvalds	ca4c7db9ef	Remove the ugly jit-style parent syntax. If somebody wants it later, we can re-do it, but for now we consider it an experiment that wasn't worth it. Git will still honor symbolic names, it just won't look up parents for you. Of course, you can always do it by hand if you want to.	20 years ago
Linus Torvalds	35ad33823e	Add "look up parent" logic for the simple names. It uses the jit syntax, at least for now. 0-xxxx is the first parent of xxxx, while 1-xxxx is the second, and so on. You can use just "-xxxx" for the first parent, but a lot of commands will think that the initial '-' implies a command line flag.	20 years ago
Linus Torvalds	3c249c9506	Add "get_sha1()" helper function. This allows the programs to use various simplified versions of the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by the .git/HEAD file etc. For example, this commit has been done with git-commit-tree $(git-write-tree) -p HEAD instead of the traditional "$(cat .git/HEAD)" syntax.	20 years ago
Junio C Hamano	40469ee9c6	[PATCH] Rename and extend read_tree_with_tree_or_commit_sha1 This patch renames read_tree_with_tree_or_commit_sha1() to read_object_with_reference() and extends it to automatically dereference not just "commit" objects but "tag" objects. With this patch, you can say e.g.: ls-tree $tag read-tree -m $(merge-base $tag $HEAD) $tag $HEAD diff-cache $tag diff-tree $tag $HEAD Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Christopher Li	812666c8e6	[PATCH] introduce xmalloc and xrealloc Introduce xmalloc and xrealloc to die gracefully with a descriptive message when out of memory, rather than taking a SIGSEGV.

Linus Torvalds	f5b913c9cb	Fix up the types in write_sha1_file Use "unsigned long" for the size, like we do everywhere else.	20 years ago
Linus Torvalds	a44c9a5e2e	Simplify "write_sha1_file()" interfaces The write function now adds the header to the file by itself, so there is no reason to duplicate it among all the users any more.	20 years ago
Andreas Gal	da6abf5d9c	[PATCH] fix segfault in fsck-cache Here is how to trigger it: echo blob 100 > .git/objects/00/ae4e8d3208e09f2cf7a38202a126f728cadb49 Then run fsck-cache. It will try to unpack after the header to calculate the hash, inflate returns total_out == 0 and memcpy() dies. The patch below seems to work with ZLIB 1.1 and 1.2.

Daniel Barkalow	8237b1854c	[PATCH] Additional functions for the objects database This adds two functions: one to check if an object is present in the local database, and one to add an object to the local database by reading it from a file descriptor and checking its hash.

Linus Torvalds	144bde78e9	Use O_NOATIME when opening the sha1 files. We really don't care about atime, and it sucks to dirty the inode cache just for it. This is more than a one-liner only because we need to be able to clear the O_NOATIME flag in case some of the objects are owned by others (in which case open will return EPERM), and because not everybody has the O_NOATIME flag.	20 years ago
Linus Torvalds	860edf7a71	Fix up some problems from the commit->tree helper patch	20 years ago
Junio C Hamano	f4913f91a9	[PATCH] Accept commit in some places when tree is needed. This patch implements read_tree_with_tree_or_commit_sha1(), which can be used when you are interested in reading an unpacked raw tree data but you do not know nor care if the SHA1 you obtained your user is a tree ID or a commit ID. Before this function's introduction, you would have called read_sha1_file(), examined its type, parsed it to call read_sha1_file() again if it is a commit, and verified that the resulting object is a tree. Instead, this function does that for you. It returns NULL if the given SHA1 is not either a tree or a commit.

Linus Torvalds	706bc531a1	Make "write_sha1_file()" exit early if the file already exists. Avoid the compression.	20 years ago
Linus Torvalds	d98b46f8d9	Do SHA1 hash _before_ compression. And add a "convert-cache" program to convert from old-style to new-style.	20 years ago
Linus Torvalds	0fcfd160b0	Split up read-cache.c into more logical clumps. Do the usage and error reporting in "usage.c", and the sha1 file accesses in "sha1_file.c". Small, nice, easily separated parts. Good.	20 years ago
