The offset of an object in the pack is recorded as a 4-byte integer in the index file. When reading the offset from the mmap'ed index in prepare_pack_revindex(), the address is dereferenced as a long*. This works fine as long as the long type is four bytes wide. On NetBSD/sparc64, however, a long is 8 bytes wide and so dereferencing the offset produces garbage.

Currently we unpack the delta data from the pack and then unpack the base object to apply that delta data to it. When getting an object that is deeply deltified, we can reduce memory footprint by unpacking the base object first and then unpacking the delta data, because we will need to keep at most one delta data in memory that way.

When generating a new pack, notice if we have already needed objects in existing packs. If an object is stored deltified, and its base object is also what we are going to pack, then reuse the existing deltified representation unconditionally, bypassing all the expensive find_deltas() and try_deltas() calls. Also, notice if what we are going to write out exactly match what is already in an existing pack (either deltified or just compressed). In such a case, we can just copy it instead of going through the usual uncompressing & recompressing cycle.

The real problem triggered an earlier fix was that an alternate entry was pointing at a removed directory. Complaining on object/pack directory that cannot be opendir-ed produces noise in an ancient repository that does not have object/pack directory and has never been packed. Detect the real user error and report it. Also if opendir failed for other reasons (e.g. no read permissions), report that as well. Spotted by Andrew Vasquez <andrew.vasquez@qlogic.com>.

Use stat() to explicitly check for existence rather than relying on the non-portable EEXIST error in sha1_file.c's safe_create_leading_directories(). There certainly are optimizations possible, but then the code becomes almost the same as that in coreutil's lib/mkdir-p.c. Other uses of EEXIST seem ok. Tested on Solaris 8, AIX 5.2L, and a few Linux versions. AIX has some unrelated (I think) failures right now; I haven't tried many recent gits there. Anyone have an old Ultrix box to break everything? ;) Also remove extraneous #includes. Everything's already in git-compat-util.h, included through cache.h.

This reverts c5ced645 commit. It turns out that doing this check every time we map the idx file is quite expensive. A corrupt idx file is caught by git-fsck-objects, so this check is not strictly necessary. In one unscientific test, 0.99.9m spent 10 seconds usertime for the same task 1.1.3 takes 37 seconds usertime. Reverting this gives us the performance of 0.99.9 back.

If the config variable 'core.sharedrepository' is set, the directories $GIT_DIR/objects/ $GIT_DIR/objects/?? $GIT_DIR/objects/pack $GIT_DIR/refs $GIT_DIR/refs/heads $GIT_DIR/refs/heads/tags are set group writable (and g+s, since the git group may be not the primary group of all users). Since all files are written as lock files first, and then moved to their destination, they do not have to be group writable. Indeed, if this leads to problems you found a bug. Note that -- as in my first attempt -- the config variable is set in the function which checks the repository format. If this were done in git_default_config instead, a lot of programs would need to be modified to call git_config(git_default_config) first.

We somehow ended up registering packs in alternate object directories as "dir/object//pack/pack-*", which confusd the update-server-info code very badly. Also we did not attempt to detect a mistake of listing the object directory itself as one of the alternates. This does not lead to incorrect behaviour, but is simply wasteful, so try to do so when we are trivially able to. Signed-off-by: NJunio C Hamano <junkio@cox.net>

Recent FAT workaround caused compilation trouble on OpenBSD; different platforms use different error codes when we try to hardlink the temporary file to its final location. Existing Coda hack also checks its own error code, but the thing is, the case we care about is if link failed for a reason other than that the final file has already existed (which would be normal, or it could mean collision). So just check the error code against EEXIST. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This starts using the "user.name" and "user.email" config variables if they exist as the default name and email when committing. This means that you don't have to use the GIT_COMMITTER_EMAIL environment variable to override your email - you can just edit the config file instead. The patch looks bigger than it is because it makes the default name and email information non-static and renames it appropriately. And it moves the common git environment variables into a new library file, so that you can link against libgit.a and get the git environment without having to link in zlib and libcrypt. In short, most of it is renaming and moving, the real change core is just a few new lines in "git_default_config()" that copies the user config values to the new base. It also changes "git-var -l" to list the config variables. Signed-off-by: NLinus Torvalds <torvalds@osdl.org> Signed-off-by: NJunio C Hamano <junkio@cox.net>

The http commit walker cannot use the same temporary file creation code because it needs to use predictable temporary filename for partial fetch continuation purposes, but the code to move the temporary file to the final location should be usable from the ordinary object creation codepath. Export move_temp_to_file from sha1_file.c and use it, while losing the custom relink_or_rename function from http-fetch.c. Also the temporary object file creation part needs to make sure the leading path exists, in preparation of the really lazy fan-out directory creation. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This makes it possible to have a "sparse" git object subdirectory structure, something that has become much more attractive now that people use pack-files all the time. As a result of pack-files, a git object directory doesn't necessarily have any individual objects lying around, and in that case it's just wasting space to keep the empty first-level object directories around: on many filesystems the 256 empty directories will be aboue 1MB of diskspace. Even more importantly, after you re-pack a project that _used_ to be unpacked, you could be left with huge directories that no longer contain anything, but that waste space and take time to look through. With this change, "git prune-packed" can just do an rmdir() on the directories, and they'll get removed if empty, and re-created on demand. This patch also tries to fix up "write_sha1_from_fd()" to use the new common infrastructure for creating the object files, closing a hole where we might otherwise leave half-written objects in the object database. [jc: I unoptimized the part that really removes the fan-out directories to ease transition. init-db still wastes 1MB of diskspace to hold 256 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories, but runs mkdir() immediately after that -- reducing the saving from 150KB to 146KB. These parts will be re-introduced when everybody has the on-demand capability.] Signed-off-by: NLinus Torvalds <torvalds@osdl.org> Signed-off-by: NJunio C Hamano <junkio@cox.net>

Upon receiving such a patch, if the patch did not apply cleanly to the target tree, the recipient can try to find the matching old objects in her object database and create a temporary tree, apply the patch to that temporary tree, and attempt a 3-way merge between the patched temporary tree and the target tree using the original temporary tree as the common ancestor.

An entry in the alternates file can name a directory relative to the object store it describes. A typical linux-2.6 maintainer repository would have "../../../torvalds/linux-2.6.git/objects" there, because the subsystem maintainer object store would live in /pub/scm/linux/kernel/git/$u/$system.git/objects/ and the object store of Linus tree is in /pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects/ This unfortunately is different from GIT_ALTERNATE_OBJECT_DIRECTORIES which is relative to the cwd of the running process, but there is no way to make it consistent with the behaviour of the environment variable. The process typically is run in $system.git/ directory for a naked repository, or one level up for a repository with a working tree, so we just define it to be relative to the objects/ directory to be different from either ;-). Later, the dumb transport could be updated to read from info/alternates and make requests for the repository the repository borrows from. Signed-off-by: NJunio C Hamano <junkio@cox.net>
