2005-10-08[PATCH] If NO_MMAP is defined, fake mmap() and munmap()Libravatar Johannes Schindelin1-0/+16
Since some platforms do not support mmap() at all, and others do only just so, this patch introduces the option to fake mmap() and munmap() by malloc()ing and read()ing explicitely. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de>
2005-10-07Show original and resulting blob object info in diff output.Libravatar Junio C Hamano1-0/+1
This adds more cruft to diff --git header to record the blob SHA1 and the mode the patch/diff is intended to be applied against, to help the receiving end fall back on a three-way merge. The new header looks like this: diff --git a/apply.c b/apply.c index 7be5041..8366082 100644 --- a/apply.c +++ b/apply.c @@ -14,6 +14,7 @@ // files that are being modified, but doesn't apply the patch // --stat does just a diffstat, and doesn't actually apply +// --show-index-info shows the old and new index info for... ... 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. The patch lifts the code to compute the hash for an on-filesystem object from update-index.c and makes it available to the diff output routine. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-01Add git-symbolic-refLibravatar Junio C Hamano1-0/+2
This adds the counterpart of git-update-ref that lets you read and create "symbolic refs". By default it uses a symbolic link to represent ".git/HEAD -> refs/heads/master", but it can be compiled to use the textfile symbolic ref. The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah .git/HEAD' have been converted to use new git-symbolic-ref command, so that they can deal with either implementation.

2005-10-01Use resolve_ref() to implement read_ref().Libravatar Junio C Hamano1-0/+1
Symbolic refs are understood by resolve_ref(), so existing read_ref() users will automatically understand them as well. Signed-off-by: Junio C Hamano <junio@twinsun.com>
2005-10-01[PATCH] Allow reading "symbolic refs" that point to other refsLibravatar Linus Torvalds1-0/+1
This extends the ref reading to understand a "symbolic ref": a ref file that starts with "ref: " and points to another ref file, and thus introduces the notion of ref aliases. This is in preparation of allowing HEAD to eventually not be a symlink, but one of these symbolic refs instead. [jc: Linus originally required the prefix to be "ref: " five bytes and nothing else, but I changed it to allow and strip any number of leading whitespaces to match what update-ref.c does.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-09-24Diff clean-up.Libravatar Junio C Hamano1-3/+3
This is a long overdue clean-up to the code for parsing and passing diff options. It also tightens some constness issues. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-20[PATCH] Return proper error valud from "parse_date()"Libravatar Linus Torvalds1-1/+1
Right now we don't return any error value at all from parse_date(), and if we can't parse it, we just silently leave the result buffer unchanged. That's fine for the current user, which will always default to the current date, but it's a crappy interface, and we might well be better off with an error message rather than just the default date. So let's change the thing to return a negative value if an error occurs, and the length of the result otherwise (snprintf behaviour: if the buffer is too small, it returns how big it _would_ have been). [ I started looking at this in case we could support date-based revision names. Looks ugly. Would have to parse relative dates.. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-20Show modified files in git-ls-filesLibravatar Junio C Hamano1-0/+1
Add -m/--modified to show files that have been modified wrt. the index. [jc: The original came from Brian Gerst on Sep 1st but it only checked if the paths were cache dirty without actually checking the files were modified. I also added the usage string and a new test.] Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-08-29Revert "Replace zero-length array decls with []."Libravatar Junio C Hamano1-4/+4
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. We would probably end up declaring with "name[1]" and teach the allocator to subtract one if we really aimed for portability, but that is left for later rounds.

2005-08-23Fix ?: statements.Libravatar Jason Riedy1-0/+4
Omitting the first branch in ?: is a GNU extension. Cute, but not supported by other compilers. Replaced mostly by explicit tests. Calls to getenv() simply are repeated on non-GNU compilers. Signed-off-by: Jason Riedy <ejr@cs.berkeley.edu>

2005-08-17[PATCH] Export relative path handling "prefix_path()" functionLibravatar Linus Torvalds1-0/+1
Not all programs necessarily have a pathspec array of pathnames, some of them (like git-update-cache) want to do things one file at a time. So export the single-path interface too. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-08-16[PATCH] Make "git diff" work inside relative subdirectoriesLibravatar Linus Torvalds1-0/+3
We always show the diff as an absolute path, but pathnames to diff are taken relative to the current working directory (and if no pathnames are given, the default ends up being all of the current working directory). Note that "../xyz" also works, so you can do cd linux/drivers/char git diff ../block and it will generate a diff of the linux/drivers/block changes.

2005-08-15Alternate object pool mechanism updates.Libravatar Junio C Hamano1-2/+3
It was a mistake to use GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable to specify what alternate object pools to look for missing objects when working with an object database. It is not a property of the process running the git commands, but a property of the object database that is partial and needs other object pools to complete the set of objects it lacks. This patch allows you to have $GIT_OBJECT_DIRECTORY/info/alternates whose contents is in exactly the same format as the environment variable, to let an object database name alternate object pools it depends on.

2005-08-06Redo the templates generation and installation.Libravatar Junio C Hamano1-4/+0
Per discussion with people interested in binary packaging, change the default template location from /etc/git-core to /usr/share/git-core hierarchy. If a user wants to run git before installing for whatever reason, in addition to adding $src to the PATH environment variable, git-init-db can be run with --template=$src/templates/blt/ parameter.

2005-08-03Renaming push.Libravatar Junio C Hamano1-0/+3
This allows git-send-pack to push local refs to a destination repository under different names. Here is the name mapping rules for refs. * If there is no ref mapping on the command line: - if '--all' is specified, it is equivalent to specifying <local> ":" <local> for all the existing local refs on the command line - otherwise, it is equivalent to specifying <ref> ":" <ref> for all the refs that exist on both sides. * <name> is just a shorthand for <name> ":" <name> * <src> ":" <dst> push ref that matches <src> to ref that matches <dst>. - It is an error if <src> does not match exactly one of local refs. - It is an error if <dst> matches more than one remote refs. - If <dst> does not match any remote refs, either - it has to start with "refs/"; <dst> is used as the destination literally in this case. - <src> == <dst> and the ref that matched the <src> must not exist in the set of remote refs; the ref matched <src> locally is used as the name of the destination. For example, - "git-send-pack --all <remote>" works exactly as before; - "git-send-pack <remote> master:upstream" pushes local master to remote ref that matches "upstream". If there is no such ref, it is an error. - "git-send-pack <remote> master:refs/heads/upstream" pushes local master to remote refs/heads/upstream, even when refs/heads/upstream does not exist. - "git-send-pack <remote> master" into an empty remote repository pushes the local ref/heads/master to the remote ref/heads/master.

2005-08-02[PATCH] Parallelize pulling by sshLibravatar barkalow@iabervon.org1-1/+2
This causes ssh-pull to request objects in prefetch() and read then in fetch(), such that it reduces the unpipelined round-trip time. This also makes sha1_write_from_fd() support having a buffer of data which it accidentally read from the fd after the object; this was formerly not a problem, because it would always get a short read at the end of an object, because the next object had not been requested. This is no longer true. Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-07-31Teach parse_commit_buffer about grafting.Libravatar Junio C Hamano1-0/+2
Introduce a new file $GIT_DIR/info/grafts (or $GIT_GRAFT_FILE) which is a list of "fake commit parent records". Each line of this file is a commit ID, followed by parent commit IDs, all 40-byte hex SHA1 separated by a single SP in between. The records override the parent information we would normally read from the commit objects, allowing both adding "fake" parents (i.e. grafting), and pretending as if a commit is not a child of some of its real parents (i.e. cauterizing).

2005-07-23[PATCH] Add update-server-info.Libravatar Junio C Hamano1-0/+3
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.

2005-07-14Make "ce_match_path()" a generic helper functionLibravatar Linus Torvalds1-0/+1
... 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.
2005-07-14Fix up read_tree() pathspec matching to use "const char **"Libravatar Linus Torvalds1-1/+1
The same way the other pathspecs work. Also fix missing success return from the matching - not that anything actually uses this yet ;)
2005-07-14Start adding interfaces to read in partial treesLibravatar Linus Torvalds1-1/+1
The same way "git-diff-tree" can limit its output to just a set of matches, we can read in just a partial tree for comparison purposes.
2005-07-13Add first cut at "git protocol" connect logic.Libravatar Linus Torvalds1-0/+10
Useful for pulling stuff off a dedicated server. Instead of connecting with ssh or just starting a local pipeline, we connect over TCP to the other side and try to see if there's a git server listening. Of course, since I haven't written the git server yet, that will never happen. But the server really just needs to listen on a port, and execute a "git-upload-pack" when somebody connects. (It should read one packet-line, which should be of the format "git-upload-pack directoryname\n" and eventually we migth have other commands the server might accept).

This patch makes the first half of write_sha1_file() and index_fd() externally visible, to allow callers to compute the object ID without actually storing it in the object database.

2005-07-06[PATCH] clone-pack.c:write_one_ref() - Create leading directories.Libravatar Junio C Hamano1-0/+2
The function write_one_ref() is passed the list of refs received from the other end, which was obtained by directory traversal under $GIT_DIR/refs; this can contain paths other than what git-init-db prepares and would fail to clone when there is such.

2005-07-05Add "git_path()" and "head_ref()" helper functions.Libravatar Linus Torvalds1-0/+1
"git_path()" returns a static pathname pointer into the git directory using a printf-like format specifier. "head_ref()" works like "for_each_ref()", except for just the HEAD.
