* connect.c: finish_connect(): allow null pid parameterFranck Bui-Huu2006-09-121-2/+11
| | | | | | | | | | | | | | git_connect() can return 0 if we use git protocol for example. Users of this function don't know and don't care if a process had been created or not, and to avoid them to check it before calling finish_connect() this patch allows finish_connect() to take a null pid. And in that case return 0. [jc: updated function signature of git_connect() with a comment on its return value. ] Signed-off-by: Franck Bui-Huu <vagabon.xyz@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Fix a memory leak in "connect.c" and die if command too long.Christian Couder2006-09-101-3/+14
| | | | | | | | | | | Use "add_to_string" instead of "sq_quote" and "snprintf", so that there is no memory allocation and no memory leak. Also check if the command is too long to fit into the buffer and die if this is the case, instead of truncating it to the buffer size.

* send-pack: remove remote reference limitAndy Whitcroft2006-09-051-1/+1
| | | | | | | | | | | | | | | | When build a pack for a push we query the remote copy for existant heads. These are used to prune unnecessary objects from the pack. As we receive the remote references in get_remote_heads() we validate the reference names via check_ref() which includes a length check; rejecting those >45 characters in size. This is a miss converted change, it was originally designed to reject messages which were less than 45 characters in length (a 40 character sha1 and refs/) to prevent comparing unitialised memory. check_ref() now gets the raw length so check for at least 5 characters.

* Replace uses of strdup with xstrdup.Shawn Pearce2006-09-021-3/+3
| | | | | | | | | | | | | | | | Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code.

* Convert memcpy(a,b,20) to hashcpy(a,b).Shawn Pearce2006-08-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | 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. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

* finish_connect(): thinkofixJunio C Hamano2006-08-151-8/+3
| | | | | | | | | | | | | All but one callers have ignore the return value from this function, but the only caller, builtin-tar-tree.c::remote_tar(), assumed it returns non-zero on failure and zero on success. The implementation however was returning either the waited pid (which must be the same as its input) or -1 (an error). Fix this thinko, while getting rid of an assignment of return value from waitpid() into a variable of type int. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Improve git-peek-remoteLinus Torvalds2006-07-041-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes git-peek-remote able to basically do everything that git-ls-remote does (but obviously just for the native protocol, so no http[s]: or rsync: support). The default behaviour is the same, but you can now give a mixture of "--refs", "--tags" and "--heads" flags, where "--refs" forces git-peek-remote to only show real refs (ie none of the fakey tag lookups, but also not the special pseudo-refs like HEAD and MERGE_HEAD). The "--tags" and "--heads" flags respectively limit the output to just regular tags and heads, of course. You can still also ask to limit them by name too. You can combine the flags, so git peek-remote --refs --tags . will show all local _true_ tags, without the generated tag lookups (compare the output without the "--refs" flag). And "--tags --heads" will show both tags and heads, but will avoid (for example) any special refs outside of the standard locations. I'm also planning on adding a "--ignore-local" flag that allows us to ask it to ignore any refs that we already have in the local tree, but that's an independent thing. All this is obviously gearing up to making "git fetch" cheaper. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

* Restore SIGCHLD to SIG_DFL where we care about waitpid().Junio C Hamano2006-06-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | It was reported that under one implementation of socks client "git clone" fails with "error: waitpid failed (No child processes)", because "git" is spawned after setting SIGCHLD to SIG_IGN. Arguably it may be a broken setting, but we should protect ourselves so that we can get reliable results from waitpid() for the children we care about. This patch resets SIGCHLD to SIG_DFL in three places: - connect.c::git_connect() - initiators of git native protocol transfer are covered with this. - daemon.c::main() - obviously. - merge-index.c::main() - obviously. There are other programs that do fork() but do not waitpid(): http-push, imap-send. upload-pack does not either, but in the case of that program, each of the forked halves runs exec() another program, so this change would not have much effect there.

* git-proxy updates.Junio C Hamano2005-11-211-7/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on top of the git-proxy mechanism Paul Collins did, and updates its configuration mechanism. * GIT_PROXY_COMMAND environment variable is used as the catch-all fallback, as in the original. This has not changed. * Renames proxy configuration variables to core.gitproxy; this has become a multi-value variable per list discussion, most notably from suggestion by Linus. [core] ;# matches www.kernel.org as well gitproxy = netcatter for kernel.org gitproxy = netscatter for sample.xz gitproxy = none for mydomain.xz gitproxy = netcatter-default The values are command names, followed by an optional " for " and domainname; the first tail-match of the domainname determines which proxy command is used. An entry without " for " matches any domain and can be used as the default. The command name "none" is special -- it tells the mechanism not to use any proxy command and use the native git:// connection. Signed-off-by: Junio C Hamano <junkio@cox.net>
* proxy-command support for git://Paul Collins2005-11-211-1/+71
| | | | | | | | | | | | | | | | | | Here is an updated patch that first looks for GIT_PROXY_COMMAND in the environment and then git.proxycommand in the repository's configuration file. I have left the calling convention the same argv[1] is the host and argv[2] is the port. I've taken the hostname parsing verbatim from git_tcp_connect(), so it should now support an explicit port number and whatever that business with the square brackets is. (Should I move this to a helper function?) Regarding internal vs. external hosts, the proxy command can simply run netcat locally to internal hosts, so perhaps that is sufficient.

* send-pack: allow generic sha1 expression on the source side.Junio C Hamano2005-08-061-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends the source side semantics to match what Linus suggested. An example: $ git-send-pack kernel.org:/pub/scm/git/git.git pu^^:master pu would allow me to push the current pu into pu, and the commit two commits before it into master, on my public repository. The revised rule for updating remote heads is as follows. $ git-send-pack [--all] <remote> [<ref>...] - When no <ref> is specified: - with '--all', it is the same as specifying the full refs/* path for all local refs; - without '--all', it is the same as specifying the full refs/* path for refs that exist on both ends; - When one or more <ref>s are specified: - a single token <ref> (i.e. no colon) must be a pattern that tail-matches refs/* path for an existing local ref. It is an error for the pattern to match no local ref, or more than one local refs. The matching ref is pushed to the remote end under the same name. - <src>:<dst> can have different cases. <src> is first tried as the tail-matching pattern for refs/* path. - If more than one matches are found, it is an error. - If one match is found, <dst> must either match no remote ref and start with "refs/", or match exactly one remote ref. That remote ref is updated with the sha1 value obtained from the <src> sha1. - If no match is found, it is given to get_extended_sha1(); it is an error if get_extended_sha1() does not find an object name. If it succeeds, <dst> must either match no remote ref and start with "refs/" or match exactly one remote ref. That remote ref is updated with the sha1 value.

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