Luben Tuikov 2e7766655a URL: allow port specification in ssh:// URLs
Allow port specification in ssh:// URLs in the
usual notation:

	ssh://[user@]host.domain[:<port>]/<path>

This allows git to be used over ssh-tunneling
networks.

Linus Torvalds 72a4f4b657 connect: accept file:// URL scheme
We might make it something like: "if you use an url, we don't default to
local", so the difference would be that

	git clone file:///directory/to/repo

would work the way it does now, but

	git clone /directory/to/repo

would default to "-l" behaviour. That kind of would make sense (and should
be easy to implement.

This adds support for "file://" URL to underlying connect
codepath to make it happen.

Matthias Lederhofer 892c41b98a introduce GIT_WORK_TREE to specify the work tree
setup_gdg is used as abbreviation for setup_git_directory_gently.

The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option).  Additionally
there is a command line option --work-tree which sets the
environment variable.

setup_gdg does the following now:

GIT_DIR unspecified
repository in .git directory
    parent directory of the .git directory is used as work tree,
    GIT_WORK_TREE is ignored

GIT_DIR unspecified
repository in cwd
    GIT_DIR is set to cwd
    see the cases with GIT_DIR specified what happens next and
    also see the note below

GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
    cwd is used as work tree

GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
    the specified work tree is used

Note on the case where GIT_DIR is unspecified and repository is in cwd:
    GIT_WORK_TREE is used but is_inside_git_dir is always true.
    I did it this way because setup_gdg might be called multiple
    times (e.g. when doing alias expansion) and in successive calls
    setup_gdg should do the same thing every time.

Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:

(1) is_bare_repository
    A repository is bare if core.bare is true or core.bare is
    unspecified and the name suggests it is bare (directory not
    named .git).  The bare option disables a few protective
    checks which are useful with a working tree.  Currently
    this changes if a repository is bare:
        updates of HEAD are allowed
        git gc packs the refs
        the reflog is disabled by default

(2) is_inside_work_tree
    True if the cwd is inside the associated working tree (if there
    is one), false otherwise.

(3) is_inside_git_dir
    True if the cwd is inside the git directory, false otherwise.
    Before this patch is_inside_git_dir was always true for bare
    repositories.

When setup_gdg finds a repository git_config(git_default_config) is
always called.  This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.

inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository.  The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

Linus Torvalds 608d48b220 Fix "getaddrinfo()" buglet
At least in Linux glibc, "getaddrinfo()" has a very irritating feature (or
bug, who knows..).

Namely if you pass it in an empty string for the service name, it will
happily and quietly consider it identical to a NULL port pointer, and
return port number zero and no errors. Which obviously will not work.

Maybe that's what it's really expected to do, although the man-page for
getaddrinfo() certainly implies that it's a bug.

So when somebody passes me a "please pull" request pointing to something
like the following

	git://git.kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb.git

(note the extraneous colon at the end of the host name), git would happily
try to connect to port 0, which would generally just cause the remote to
not even answer, and the "connect()" will take a long time to time out.

So to work around the glibc feature/bug, just notice this empty port case
automatically. Also, add the port information to the error information
when it fails to look up (maybe it's the host-name that fails, maybe it's
the port-name - we should print out both).

Junio C Hamano cc44c7655f Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily.  Leftover from this will be fixed in a separate step, including
idiotic conversions like

    if (!strncmp("foo", arg, 3))

  =>

Junio C Hamano ec587fde0a Make sure git_connect() always give two file descriptors.
Earlier, git_connect() returned the same fd twice or two
separate fds, depending on the way the connection was made (when
we are talking to the other end over a single socket, we used
the same fd twice, and when our end is connected to a pipepair
we used two).

This forced callers who do close() and dup() to really care
which was which, and most of the existing callers got this
wrong, although without much visible ill effect.  Many were
closing the same fd twice when we are talking over a single
socket, and one was leaking a fd.

This fixes it to uniformly use two separate fds, so if somebody
wants to close only reader side can just do close() on it
without worrying about it accidentally also closing the writer
side or vice versa.

     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).

Junio C Hamano d4f694ba89 Allow git push to delete remote ref.
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.

Junio C Hamano 29561ad0ad refs outside refs/{heads,tags} match less strongly.
This changes the refname matching logic used to decide which ref
is updated with git-send-pack.  We used to error out when
pushing 'master' when the other end has both 'master' branch and
a tracking branch 'remotes/$name/master' but with this, 'master'
matches only 'refs/heads/master' when both and no other 'master'
exist.

Pushing 'foo' when both heads/foo and tags/foo exist at the
remote end is still considered an error and you would need to
disambiguate between them by being more explicit.

When neither heads/foo nor tags/foo exists at the remote,
pushing 'foo' when there is only remotes/origin/foo is not
ambiguous, while it still is ambiguous when there are more than
one such weaker match (remotes/origin/foo and remotes/alt/foo,
for example).

Andy Whitcroft c41e20b30b send-pack: remove remote reference limit
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.

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*.

Linus Torvalds 2718ff098a Improve git-peek-remote
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.

Junio C Hamano f0b7367cb1 Restore SIGCHLD to SIG_DFL where we care about waitpid().
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.

 * 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.

Paul Collins f801477645 proxy-command support for git://
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.

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"))

Junio C Hamano 15e02b372d send-pack: allow generic sha1 expression on the source side.
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.

Junio C Hamano f88395ac23 Renaming push.
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.

Linus Torvalds 2386d65822 Add first cut at "git protocol" connect logic.
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).

Junio C Hamano b10d0ec732 [PATCH] Use sq_quote() to properly quote the parameter to call shell.
This tries to be more lenient to the users and stricter to the
attackers by quoting the input properly for shell safety,
instead of forbidding certain characters from the input.

Things to note:

 - We do not quote "prog" parameter (which comes from --exec).
   The user should know what he is doing.  --exec='echo foo'
   will supply the first two parameters to the resulting
   command, while --exec="'echo foo'" will give the first
   parameter, a single string with a space inside.

 - We do not care too much about leaking the sq_quote() output
   just before running exec().
