* ph/transport-with-gitfile:
Fix is_gitfile() for files too small or larger than PATH_MAX to be a gitfile
Add test showing git-fetch groks gitfiles
Teach transport about the gitfile mechanism
Learn to handle gitfiles in enter_repo
enter_repo: do not modify input
Move most of the code from read_bundle_header() to parse_bundle_header()
that takes a file descriptor that is already opened for reading, and make
the former responsible only for opening the file and noticing errors.
As a logical consequence of this, is_bundle() helper function can be
implemented as a non-complaining variant of read_bundle_header() that
does not return an open file descriptor, and can be used to tighten
the check used to decide the use of bundle transport in transport_get()
function.

The logic to check whether a file is a gitfile used the heuristics that
a gitfile cannot be larger than PATH_MAX or smaller than 10 bytes (as
its contents is "gitdir: " followed by a path) and returned early.
But it returned with a wrong value. It should have said "this cannot
possibly be a gitfile" by returning 0, but it returned 1 instead. Our
test cases do not cover this, as the bundle files produced are smaller
than PATH_MAX, except on Windows.
While at it, fix the faulty logic that the path stored in a gitfile cannot
be larger than PATH_MAX-sizeof("gitdir: ").

suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.

The transport_get() function assumes that a regular file is a
bundle rather than a local git directory. Look inside the file
for the telltale "gitlink: " header to see if it is actually a

With the usual "git" transport, a large-ish transfer with "git fetch" and
"git pull" give progress eye-candy to avoid boring users. However, not
when they are reading from a bundle. I.e.
$ git pull ../git-bundle.bndl master
This teaches bundle.c:unbundle() to give "-v" option to index-pack and
tell it to give progress bar when transport decides it is necessary.
The operation in the other direction, "git bundle create", could also
learn to honor --quiet but that is a separate issue.

When working with submodules it is easy to forget to push a
submodule to the server but pushing a super-project that
contains a commit for that submodule. The result is that the
superproject points at a submodule commit that is not available
on the server.
This adds the option --recurse-submodules=check to push. When
using this option git will check that all submodule commits that
are about to be pushed are present on a remote of the submodule.

The foreach_alt_odb function triggers a callback for each
alternate object db we have, with room for a single void
pointer as data. Currently, we always call refs_from_alternate_cb
as the callback function, and then pass another callback (to
receive each ref individually) as the void pointer.
This has two problems:
1. C technically forbids stuffing a function pointer into
a "void *". In practice, this probably doesn't matter
on any architectures git runs on, but it never hurts to
follow the letter of the law.
2. There is no room for an extra data pointer. Indeed, the
alternate_ref_fn that refs_from_alternate_cb calls
takes a void* for data, but we always pass it NULL.
Instead, let's properly stuff our function pointer into a
data struct, which also leaves room for an extra
caller-supplied data pointer. And to keep things simple for
existing callers, let's make a for_each_alternate_ref
function that takes care of creating the extra struct.

The receiving end of "git push" advertises the objects that the repository
itself does not use, but are at the tips of refs in other repositories
whose object databases are used as alternates for it. This helps it avoid
having to receive (and the pusher having to send) objects that are already
available to the receiving repository via the alternates mechanism.
Tweak the helper function that implements this feature, and move it to
transport.[ch] for future reuse by other programs.

When pushing via builtin transports (like file://, git://), the
underlying transport helper (in this case, git-pack-objects) did not get
the --progress option, even if it was passed to git push.
Fix this, and update the tests to reflect this.
Note that according to the git-pack-objects documentation, we can safely
apply the usual --progress semantics for the transport commands like
clone and fetch (and for pushing over other smart transports).

The script calling git push --porcelain --dry-run can see clearly from the
output if an update was rejected. However, it will probably need to distinguish
this condition from the push failing for other reasons, such as the remote not
being reachable.
This patch modifies git push --porcelain to print "Done" after the rest of its
output unless any errors have occurred. For the purpose of the "Done" line,
knowing a ref will be rejected in a --dry-run does not count as an error.
Actual rejections in non --dry-run pushes do count as errors.

Set transport->progress in transport.c::transport_set_verbosity() after
checking for the appropriate conditions (eg. --progress, isatty(2)),
and thereafter use it without having to check again.
The rules used are as follows (processing aborts when a rule is
satisfied):
1. Report progress, if force_progress is 1 (ie. --progress).
2. Don't report progress, if verbosity < 0 (ie. -q/--quiet).
3. Report progress if isatty(2) is 1.
This changes progress reporting behaviour such that if both --progress
and --quiet are specified, progress is reported.
In two areas, the logic to determine whether to *not* show progress is
changed to simply use the negation of transport->progress. This changes
behaviour in some ways (see previous paragraph for details).

It is a separate configuration option in order to allow a sensible

for repositories or which require urls that do not specify the system
used by the repository at that location. However, this only affects
how the name of the helper is determined, not anything about the

location is not specified with a url.
Also, have the message for a fetch say "foreign" if there is no url.

The git-remote-curl backend detects if the remote server supports
the git-receive-pack service, and if so, runs git-send-pack in a
pipe to dump the command and pack data as a single POST request.
The advertisements from the server that were obtained during the
discovery are passed into git-send-pack before the POST request
starts. This permits git-send-pack to operate largely unmodified.
For smaller packs (those under 1 MiB) a HTTP/1.0 POST with a
Content-Length is used, permitting interaction with any server.
The 1 MiB limit is arbitrary, but is sufficent to fit most deltas
created by human authors against text sources with the occasional
small binary file (e.g. few KiB icon image). The configuration
option http.postBuffer can be used to increase (or shink) this
buffer if the default is not sufficient.
For larger packs which cannot be spooled entirely into the helper's
memory space (due to http.postBuffer being too small), the POST
request requires HTTP/1.1 and sets "Transfer-Encoding: chunked".
This permits the client to upload an unknown amount of data in one
HTTP transaction without needing to pregenerate the entire pack
file locally.

cmd_ls_remote() was calling transport_get() with a NULL remote and a
non-NULL url in the case where it was run outside a git
repository. This involved a bunch of ill-tested special
cases. Instead, simply get the struct remote for the URL with
remote_get(), which works fine outside a git repository, and can also
take global options into account.
This fixes a tiny and obscure bug where "git ls-remote" without a repo
didn't support global url.*.insteadOf, even though "git clone" and
"git ls-remote" in any repo did.
Also, enforce that all callers provide a struct remote to transport_get().

The remote helper interface now supports the push capability,
which can be used to ask the implementation to push one or more
specs to the remote repository. For remote-curl we implement this
by calling the existing WebDAV based git-http-push executable.
Internally the helper interface uses the push_refs transport hook
so that the complexity of the refspec parsing and matching can be
reused between remote implementations. When possible however the
helper protocol uses source ref name rather than the source SHA-1,
thereby allowing the helper to access this name if it is useful.
>From Clemens Buchacher <drizzd@aon.at>:
update http tests according to remote-curl capabilities
o Pushing packed refs is now fixed.
o The transport helper fails if refs are already up-to-date. Add
a test for that.
o The transport helper will notice if refs are already
up-to-date. We therefore need to update server info in the
unpacked-refs test.
o The transport helper will purge deleted branches automatically.
o Use a variable ($ORIG_HEAD) instead of full SHA-1 name.

If all refs sent by the remote repo during a fetch are reachable
locally, then no further conversation is performed with the remote. This
check is skipped when the --depth argument is provided to allow the
deepening of a shallow clone which corresponding remote repo has no
changed.
However, some additional filtering was added in commit c29727d5 to
remove those refs which are equal on both sides. If the remote repo has
not changed, then the list of refs to give the remote process becomes
empty and simply attempting to deepen a shallow repo always fails.
Let's stop being smart in that case and simply send the whole list over
when that condition is met. The remote will do the right thing anyways.
Test cases for this issue are also provided.

Convert existing die(..., strerror(errno)) to die_errno()
die_errno(): double % in strerror() output just in case
Introduce die_errno() that appends strerror(errno) to die()
In the case where a program was not found, it was still the task of the
caller to report an error to the user. Usually, this is an interesting case
but only few callers actually reported a specific error (though many call
sites report a generic error message regardless of the cause).
With this change the error is reported by run_command, but since there is
one call site in git.c that does not want that, an option is added to
struct child_process, which is used to turn the error off.

The motivation for this change is that system call failures are serious
errors that should be reported to the user, but only few callers took the
burden to decode the error codes that the functions returned into error
messages.
If at all, then only an unspecific error message was given. A prominent
example is this:
$ git upload-pack . | :
fatal: unable to run 'git-upload-pack'
In this example, git-upload-pack, the external command invoked through the
git wrapper, dies due to SIGPIPE, but the git wrapper does not bother to
report the real cause. In fact, this very error message is copied to the
syslog if git-daemon's client aborts the connection early.
With this change, system call failures are reported immediately after the
failure and only a generic failure code is returned to the caller. In the
above example the error is now to the point:
$ git upload-pack . | :
error: git-upload-pack died of signal
Note that there is no error report if the invoked program terminated with
a non-zero exit code, because it is reasonable to expect that the invoked
program has already reported an error. (But many run_command call sites
nevertheless write a generic error message.)
There was one special return code that was used to identify the case where
run_command failed because the requested program could not be exec'd. This
special case is now treated like a system call failure with errno set to
ENOENT. No error is reported in this case, because the call site in git.c
expects this as a normal result. Therefore, the callers that carefully
decoded the return value still check for this condition.

I used the following criteria when selecting the code for replacement:
- it was already printing a warning for the unlink failures
- it is in a function which already printing something or is
called from such a function
- it is in a static function, returning void and the function is only
called from a builtin main function (cmd_)
- it is in a function which handles emergency exit (signal handlers)
- it is in a function which is obvously cleaning up the lockfiles

When pulling from a remote, the full URL including username
is by default added to the commit message. Since it adds
very little value but could be used by malicious people to
glean valid usernames (with matching hostnames), we're far
better off just stripping the username before storing the
remote URL locally.
Note that this patch has no lasting visible effect when
"git pull" does not create a merge commit. It simply
alters what gets written to .git/FETCH_HEAD, which is used

Earlier, the rsync tests were disabled by default, as they needed a

rsync transport only allowed full URLs of the form
rsync://<host>/<path>
Relaxing the URLs to allow
rsync:<path>
permitted the change in the tests to run whenever rsync is available,
without requiring a fully configured and running rsyncd.
While at it, the tests were fixed so that they run in directories with a
