2006-12-20simplify inclusion of system header files.Junio C Hamano
This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-17Default GIT_COMMITTER_NAME to login name in recieve-pack.Shawn O. Pearce
If GIT_COMMITTER_NAME is not available in receive-pack but reflogs are enabled we would normally die out with an error message asking the user to correct their environment settings. Now that reflogs are enabled by default in (what we guessed to be) non-bare Git repositories this may cause problems for some users who don't have their full name in the gecos field and who don't have access to the remote system to correct the problem. So rather than die()'ing out in receive-pack when we try to log a ref change and have no committer name we default to the username, as obtained from the host's password database.

2006-12-07change the unpack limit treshold to a saner valueNicolas Pitre
Currently the treshold is 5000. The likelihood of this value to ever be crossed for a single push is really small making it not really useful. The optimal treshold for a pure space saving on a filesystem with 4kb blocks is 3. However this is likely to create many small packs concentrating a large number of files in a single directory compared to the same objects which are spread over 256 directories when loose. This means we would need 512 objects per pack on average to approximagte the same directory cost (a pack has 2 files because of the index). But 512 is a really high value just like 5000 since most pushes are unlikely to have that many objects. So let's try with a value of 100 which should have a good balance between small pushes going to be exploded into loose objects and large pushes kept as whole packs. This is not a replacement for periodic repacks of course. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-11-24Allow git push to delete remote ref.Junio C Hamano
This allows you to say git send-pack $URL :refs/heads/$branch to delete the named remote branch. The refspec $src:$dst means replace the destination ref with the object known as $src on the local side, so this is a natural extension to make an empty $src mean "No object" to delete the target.

2006-11-03Teach receive-pack how to keep pack files based on object count.Shawn Pearce
Since keeping a pushed pack or exploding it into loose objects should be a local repository decision this teaches receive-pack to decide if it should call unpack-objects or index-pack --stdin --fix-thin based on the setting of receive.unpackLimit and the number of objects contained in the received pack. If the number of objects (hdr_entries) in the received pack is below the value of receive.unpackLimit (which is 5000 by default) then we unpack-objects as we have in the past. If the hdr_entries >= receive.unpackLimit then we call index-pack and ask it to include our pid and hostname in the .keep file to make it easier to identify why a given pack has been kept in the repository. Currently this leaves every received pack as a kept pack. We really don't want that as received packs will tend to be small. Instead we want to delete the .keep file automatically after all refs have been updated. That is being left as room for future improvement. Signed-off-by: Shawn O.

2006-09-21Add callback data to for_each_ref() family.Junio C Hamano
This is a long overdue fix to the API for for_each_ref() family of functions. It allows the callers to specify a callback data pointer, so that the caller does not have to use static variables to communicate with the callback funciton. The updated for_each_ref() family takes a function of type int (*fn)(const char *, const unsigned char *, void *) and a void pointer as parameters, and calls the function with the name of the ref and its SHA-1 with the caller-supplied void pointer as parameters. The commit updates two callers, builtin-name-rev.c and builtin-pack-refs.c as an example. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-20add receive.denyNonFastforwards config variableJohannes Schindelin

This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet.

2006-01-14Exec git programs without using PATH.Michal Ostrowski
The git suite may not be in PATH (and thus programs such as git-send-pack could not exec git-rev-list). Thus there is a need for logic that will locate these programs. Modifying PATH is not desirable as it result in behavior differing from the user's intentions, as we may end up prepending "/usr/bin" to PATH. - git C programs will use exec*_git_cmd() APIs to exec sub-commands. - exec*_git_cmd() will execute a git program by searching for it in the following directories: 1. --exec-path (as used by "git") 2. The GIT_EXEC_PATH environment variable. 3. $(gitexecdir) as set in Makefile (default value $(bindir)). - git wrapper will modify PATH as before to enable shell scripts to invoke "git-foo" commands. Ideally, shell scripts should use the git wrapper to become independent of PATH, and then modifying PATH will not be necessary.

2006-01-07[PATCH] Compilation: zero-length array declaration.Junio C Hamano
ISO C99 (and GCC 3.x or later) lets you write a flexible array at the end of a structure, like this: struct frotz { int xyzzy; char nitfol[]; /* more */ }; GCC 2.95 and 2.96 let you to do this with "char nitfol[0]"; unfortunately this is not allowed by ISO C90. This declares such construct like this: struct frotz { int xyzzy; char nitfol[FLEX_ARRAY]; /* more */ }; and git-compat-util.h defines FLEX_ARRAY to 0 for gcc 2.95 and empty for others. If you are using a C90 C compiler, you should be able to override this with CFLAGS=-DFLEX_ARRAY=1 from the command line of "make". Signed-off-by: Junio C Hamano <junkio@cox.net>

This reverts 6c5f9baa3bc0d63e141e0afc23110205379905a4 commit, whose change breaks gcc-2.95. Not that I ignore portability to compilers that are properly C99, but keeping compilation with GCC working is more important, at least for now.

2005-08-01[PATCH] Added hook in git-receive-packJosef Weidendorfer
Just before updating a ref, $GIT_DIR/hooks/update refname old-sha1 new-sha1 is called if executable. The hook can decline the ref to be updated by exiting with a non-zero status, or allow it to be updated by exiting with a zero status. The mechanism also allows e.g sending of a mail with pushed commits on the remote repository. Documentation update with an example hook is included. jc: The credits of the basic idea and initial implementation go to Josef, but I ended up rewriting major parts of his patch, so bugs are all mine. Also I changed the semantics for the hook from his original version (which were post-update hook) so that the hook can optionally decline to update the ref, and also can be used to implement the overall cleanups. The latter was primarily to implement a suggestion from Linus that calling update-server-info should be made optional. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-07-24[PATCH] Add update-server-info.Junio C Hamano
The git-update-server-info command prepares informational files to help clients discover the contents of a repository, and pull from it via a dumb transport protocols. Currently, the following files are produced. - The $repo/info/refs file lists the name of heads and tags available in the $repo/refs/ directory, along with their SHA1. This can be used by git-ls-remote command running on the client side. - The $repo/info/rev-cache file describes the commit ancestry reachable from references in the $repo/refs/ directory. This file is in an append-only binary format to make the server side friendly to rsync mirroring scheme, and can be read by git-show-rev-cache command. - The $repo/objects/info/pack file lists the name of the packs available, the interdependencies among them, and the head commits and tags contained in them. Along with the other two files, this is designed to help clients to make smart pull decisions. The git-receive-pack command is changed to invoke it at the end, so just after a push to a public repository finishes via "git push", the server info is automatically updated. In addition, building of the rev-cache file can be done by a standalone git-build-rev-cache command separately.

2005-06-30Do ref matching on the sender side rather than on receiverLinus Torvalds
This makes the receiver always send a full list of valid refs, which will allow us to do better packs, as well as handle creation of new refs. Eventually. Right now we just moved the matching and enabled it. So now you can do git-send-pack host:path branch1 branch2 to only send branches "branch1" and "branch2".
2005-06-30Add support for "forcing" a ref on the remote sideLinus Torvalds
A "old ref" of all zeroes is considered a "don't care" ref, and allows us to say "write the new ref regardless of what the old ref contained (or even if it existed at all)". This allows (if git-send-pack were to do it) creating new refs, and fixing up old ones.
