When we push to update an existing ref, if:
* the object at the tip of the remote is not a commit; or
* the object we are pushing is not a commit,
it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge". We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.
If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged. In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time. And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage. As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.
In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.
Introduce new rejection reasons and reword the messages
appropriately.

The "nonfastforward" and "update" fields are only used while
deciding what value to assign to the "status" locally in a single
function. Remove them from the "struct ref".
The "requires_force" field is not used to decide if the proposed
update requires a --force option to succeed, or to record such a
decision made elsewhere. It is used by status reporting code that
the particular update was "forced". Rename it to "forced_update",
and move the code to assign to it around to further clarify how it
is used and what it is used for.

Add support for a pre-push hook which can be used to determine if the
set of refs to be pushed is suitable for the target repository. The
hook is run with two arguments specifying the name and location of the
destination repository.
Information about what is to be pushed is provided by sending lines of
the following form to the hook's standard input:
<local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF
If the hook exits with a non-zero status, the push will be aborted.
This will allow the script to determine if the push is acceptable based
on the target repository and branch(es), the commits which are to be
pushed, and even the source branches in some cases.

Pushing a non-fast-forward update to a remote repository will result in
an error, but the hint text doesn't provide the correct resolution in
every case. Give better resolution advice in three push scenarios:
1) If you push your current branch and it triggers a non-fast-forward
error, you should merge remote changes with 'git pull' before pushing
again.
2) If you push to a shared repository others push to, and your local
tracking branches are not kept up to date, the 'matching refs' default
will generate non-fast-forward errors on outdated branches. If this is
your workflow, the 'matching refs' default is not for you. Consider
setting the 'push.default' configuration variable to 'current' or
'upstream' to ensure only your current branch is pushed.
3) If you explicitly specify a ref that is not your current branch or
push matching branches with ':', you will generate a non-fast-forward
error if any pushed branch tip is out of date. You should checkout the
offending branch and merge remote changes before pushing again.
Teach transport.c to recognize these scenarios and configure push.c
to hint for them. If 'git push's default behavior changes or we
discover more scenarios, extension is easy. Standardize on the
advice API and add three new advice variables, 'pushNonFFCurrent',
'pushNonFFDefault', and 'pushNonFFMatching'. Setting any of these
to 'false' will disable their affiliated advice. Setting
'pushNonFastForward' to false will disable all three, thus preserving the
config option for users who already set it, but guaranteeing new
users won't disable push advice accidentally.

connect.c: drop path_match function
fetch-pack: match refs exactly
t5500: give fully-qualified refs to fetch-pack
drop "match" parameter from get_remote_heads
Providing a single "-v" to "git push" currently does
nothing. Giving two flags ("git push -v -v") turns on the
first level of verbosity.
This is caused by a regression introduced in 8afd8dc (push:
support multiple levels of verbosity, 2010-02-24). Before
the series containing 8afd8dc, the verbosity handling for
fetching and pushing was completely separate. Commit bde873c
refactored the verbosity handling out of the fetch side, and
then 8afd8dc converted push to use the refactored code.
However, the fetch and push sides numbered and passed along
their verbosity levels differently. For both, a verbosity
level of "-1" meant "quiet", and "0" meant "default output".
But from there they differed.
For fetch, a verbosity level of "1" indicated to the "fetch"
program that it should make the status table slightly more
verbose, showing up-to-date entries. A verbosity level of
"2" meant that we should pass a verbose flag to the
transport; in the case of fetch-pack, this displays protocol
debugging information.
As a result, the refactored code in bde873c checks for
"verbosity >= 2", and only then passes it on to the
transport. From the transport code's perspective, a
verbosity of 0 or 1 both meant "0".
Push, on the other hand, does not show its own status table;
that is always handled by the transport layer or below
(originally send-pack itself, but these days it is done by
the transport code). So a verbosity level of 1 meant that we
should pass the verbose flag to send-pack, so that it knows
we want a verbose status table. However, once 8afd8dc
switched it to the refactored fetch code, a verbosity level
of 1 was now being ignored. Thus, you needed to
artificially bump the verbosity to 2 (via "-v -v") to have
any effect.
We can fix this by letting the transport code know about the
true verbosity level (i.e., let it distinguish level 0 or
1).
We then have to also make an adjustment to any transport
methods that assumed "verbose > 0" meant they could spew
lots of debugging information. Before, they could only get
"0" or "2", but now they will also receive "1". They need to
adjust their condition for turning on such spew from
"verbose > 0" to "verbose > 1".

The get_remote_heads function reads the list of remote refs
during git protocol session. It dates all the way back to
def88e9 (Commit first cut at "git-fetch-pack", 2005-07-04).
At that time, the idea was to come up with a list of refs we
were interested in, and then filter the list as we got it
from the remote side.
Later, 1baaae5 (Make maximal use of the remote refs,
2005-10-28) stopped filtering at the get_remote_heads layer,
letting us use the non-matching refs to find common history.

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.

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.

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).

transport_get_remote_refs() in tranport.c checks transport->remote_refs
to determine whether transport->get_refs_list() should be invoked. The
logic is "if it is NULL, we haven't run ls-remote to find out yet".
However, transport->remote_refs could still be NULL while cloning from
an empty repository. This causes get_refs_list() to be run unnecessarily.

If this is set, the url is not required, and the transport always uses

It is a separate configuration option in order to allow a sensible
configuration for foreign systems which either have no meaningful urls
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
interaction with the helper, and the contruction is such that, if the

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.

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.

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

In the case where a program was not found, it was still the task of the

but only few callers actually reported a specific error (though many call
sites report a generic error message regardless of the cause).

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.

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
by "git merge" to automagically create its messages.

Earlier, the rsync tests were disabled by default, as they needed a
running rsyncd daemon. This was only due to the limitation that our
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
space in their name.

For native-protocol pushes (and other protocols as they are converted
to the new method), this moves the refspec match, tracking update, and
report message out of send-pack() and into transport_push(), where it
can be shared completely with other protocols. This also makes fetch
and push more similar in terms of what code is in what file.

A new inline function is_dot_or_dotdot is used to check if the
directory name is either "." or "..". It returns a non-zero value if
the given string is "." or "..". It's applicable to a lot of Git
source code.

With all calls to alloc_ref() gone, we can remove it and then we're free
to give alloc_ref_from_str() the shorter name. It's a much nicer
interface, as the callers always need to have a name string when they
allocate a ref anyway and don't need to calculate and pass its length+1
any more.

Replace pairs of alloc_ref() and strcpy() with alloc_ref_from_str(),
simplifying the code.
In connect.c, also a pair of alloc_ref() and memcpy() is replaced --
the additional cost of a strlen() call should not have too much of an
impact. Consistency and simplicity are more important.
In remote.c, the code was allocating 11 bytes more than needed for
the name part, but I couldn't see them being used for anything.

The new -v option forces the progressbar, even in case the output
is not a terminal. This can be useful if the caller is an IDE or
wrapper which wants to scrape the progressbar from stderr and show
its information in a different format.

"git push" enhancement allows the receiving end to report not only its own
refs but refs in repositories it borrows from via the alternate object
store mechanism. By telling the sender that objects reachable from these
extra refs are already complete in the receiving end, the number of
objects that need to be transfered can be cut down.
These entries are sent over the wire with string ".have", instead of the
actual names of the refs. This string was chosen so that they are ignored
by older programs at the sending end. If we sent some random but valid
looking refnames for these entries, "matching refs" rule (triggered when
running "git push" without explicit refspecs, where the sender learns what
refs the receiver has, and updates only the ones with the names of the
refs the sender also has) and "delete missing" rule (triggered when "git
push --mirror" is used, where the sender tells the receiver to delete the
refs it itself does not have) would try to update/delete them, which is
not what we want.
This prepares the send-pack (and "push" that runs native protocol) to
accept extended existing ref information and make use of it. The ".have"
entries are excluded from ref matching rules, and are exempt from deletion
rule while pushing with --mirror option, but are still used for pack
generation purposes by providing more "bottom" range commits.

Currently, when cloning from invalid HTTP URL, git clone will possibly
return curl error, then a confusing message about remote HEAD and then
return success and leave an empty repository behind, confusing either
the end-user or the automated service calling it (think repo.or.cz).
This patch changes the error() calls in get_refs_via_curl() to die()s,
akin to the other get_refs_*() functions.

The earlier built-in conversion seems to have broken "git-clone"; this
teaches the command to honor the "-q" option again when talking to the
remote end over native transports (file://, git:// and ssh://).

Fetching the objects doesn't actually modify the list in any of the
code paths, so this will allow code that fetches the entire (const)

If the remote peer upload-pack process supports the include-tag
protocol extension then we can avoid running a second fetch cycle
on the client side by letting the server send us the annotated tags
along with the objects it is packing for us. In the following graph
we can now fetch both "tag1" and "tag2" on the same connection that
we fetched "master" from the remote when we only have L available
on the local side:
T - tag1 S - tag2
/ /
L - o ------ o ------ B
\ \
\ \
origin/master master
The objects for "tag1" are implicitly downloaded without our direct
knowledge. The existing "quickfetch" optimization within git-fetch
discovers that tag1 is complete after the first connection and does
not open a second connection.

We always report to the user the list of refs we got from the first
connection, even if we do multiple connections. But we should always
use each connection's own list of refs in the communication with the
server, in case we got a different server out of DNS rotation or the
timing was surprising or something.

In transport.c, proxy setting (the one from the remote conf) was set through
curl_easy_setopt() call, while http.c already does the same with the
http.proxy setting. We now just use this infrastructure instead, and make
http_init() now take the struct remote as argument so that it can take the
http_proxy setting from there, and any other property that would be added
later.
At the same time, we make get_http_walker() take a struct remote argument
too, and pass it to http_init(), which makes remote defined proxy be used
for more than get_refs_via_curl().
We leave out http-fetch and http-push, which don't use remotes for the
moment, purposefully.
