* Support receiving server capabilitiesJohannes Schindelin2005-10-28
| | | | | | | | | | | | | | | | | | This patch implements the client side of backward compatible upload-pack protocol extension, <20051027141619.0e8029f2.vsu@altlinux.ru> by Sergey. The updated server can append "server_capabilities" which is supposed to be a string containing space separated features of the server, after one of elements in the initial list of SHA1-refname line, hidden with an embedded NUL. After get_remote_heads(), check if the server supports the feature like if (server_supports("multi_ack")) do_something(); Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
* pack-objects: Allow use of pre-generated pack.Junio C Hamano2005-10-26
| | | | | | | | | | | | | | | | git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache directory, when a necessary pack is found. This is hopefully useful when upload-pack (called from git-daemon) is expected to receive requests for the same set of objects many times (e.g full cloning request of any project, or updates from the set of heads previous day to the latest for a slow moving project). Currently git-pack-objects does *not* keep pack files it creates for reusing. It might be useful to add --update-cache option to it, which would allow it store pack files it created in the pack-cache directory, and prune rarely used ones from it.

* Ignore funny refname sent from remoteJunio C Hamano2005-10-15
| | | | | | | | | This allows the remote side (most notably, upload-pack) to show additional information without affecting the downloader. Peek-remote does not ignore them -- this is to make it useful for Pasky's automatic tag following. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Unlocalized isspace and friendsLinus Torvalds2005-10-14
| | | | | | | | | Do our own ctype.h, just to get the sane semantics: we want locale-independence, _and_ we want the right signed behaviour. Plus we only use a very small subset of ctype.h anyway (isspace, isalpha, isdigit and isalnum). Signed-off-by: Junio C Hamano <junkio@cox.net>
* Keep track of whether a pack is local or notLinus Torvalds2005-10-13

* Use git config file for committer name and email infoLinus Torvalds2005-10-11
| | | | | | | | | | | | | | | | | | | | | | 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: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

* Use the same move_temp_to_file in git-http-fetch.Junio C Hamano2005-10-10
| | | | | | | | | | | | | | | | | 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: Junio C Hamano <junkio@cox.net>
* Add ".git/config" file parserLinus Torvalds2005-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a first cut at a very simple parser for a git config file. The format of the file is a simple ini-file like thing, with simple variable/value pairs. You can (and should) make the variables have a simple single-level scope, ie a valid file looks something like this: # # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = "/usr/local/bin/gnu-diff -u" renames = true which parses into three variables: "core.filemode" is associated with the string "false", and "diff.external" gets the appropriate quoted value. Right now we only react to one variable: "core.filemode" is a boolean that decides if we should care about the 0100 (user-execute) bit of the stat information. Even that is just a parsing demonstration - this doesn't actually implement that st_mode compare logic itself. Different programs can react to different config options, although they should always fall back to calling "git_default_config()" on any config option name that they don't recognize.

* [PATCH] If NO_MMAP is defined, fake mmap() and munmap()Johannes Schindelin2005-10-08

* Show original and resulting blob object info in diff output.Junio C Hamano2005-10-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add git-symbolic-refJunio C Hamano2005-10-01
| | | | | | | | | | | | | 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.

* [PATCH] Allow reading "symbolic refs" that point to other refsLinus Torvalds2005-10-01
| | | | | | | | | | | | | | | | 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>

* [PATCH] Return proper error valud from "parse_date()"Linus Torvalds2005-09-20
| | | | | | | | | | | | | | | | | | | 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.

Not that I ignore portability to compilers that are properly C99, but keeping compilation with GCC working is more important, at least for now.

* Alternate object pool mechanism updates.Junio C Hamano2005-08-15

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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).

* [PATCH] Add update-server-info.Junio C Hamano2005-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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).
