Introduce usagef() that takes a printf-style format
Some new callers would want to use printf-like formatting, when issuing
their usage messages. An option is to change usage() itself also be like
printf(), which would make it similar to die() and warn().
But usage() is typically fixed, as opposed to die() and warn() that gives
diagnostics depending on the situation. Indeed, the majority of strings
given by existing callsites to usage() are fixed strings. If we were to
make usage() take printf-style format, they all need to be changed to have
"%s" as their first argument.
So instead, introduce usagef() so that limited number of callers can use
it.

Dump usage instead. Humans wanting to pass the URL -h/ to curl for some
reason can use 'git http-push -h/' explicitly. Scripts expecting to
access an HTTP repository at URL '-h' will break, though.
Also delay finding a git directory until after option parsing, so
"http-push -h" can be used outside any git repository.

format-patch: Add "--no-stat" as a synonym for "-p"
"-p" means "generate patch" in 'git log' and 'git diff', so it's
quite surprising that it means "suppress diffstat" in

Keep the "-p" option for backward compatibility, but add
"--no-stat" as a more intuitive synonym. For backward compatibility
with scripts, we must allow combinations of --stat and --no-stat.

format-patch documentation: Remove diff options that are not useful
To simplify reading the documentation for format-patch, remove the
description of common diff options that are not useful for the
purpose of the command (i.e. "Prepare patches for e-mail submission").
Specifically, this removes the description of the following options:
Jeff King recently reinstated -p to suppress the default diffstat
(as -p used to work before 68daa64, about 14 months ago).
However, -p is also needed in combination with certain options
(e.g. --stat or --numstat) in order to produce any patch at all.
The documentation does not mention this.
Since the purpose of format-patch is to produce a patch that
can be emailed, it does not make sense that certain combination
of options will suppress the generation of the patch itself.
Therefore:
* Update 'git format-patch' to always generate a patch.
* Since the --name-only, --name-status, and --check suppresses
the generation of the patch, disallow those options,
and remove the description of them in the documentation.
* Remove the reference to -p in the description of -U.
* Remove the descriptions of the options that are synonyms for -p
plus another option (--patch-with-raw and --patch-with-stat).
* While at it, slightly tweak the description of -p itself
to say that it generates "plain patches", so that you can
think of -p as "plain patch" as an mnemonic aid.

t5551-http-fetch: Work around broken Accept header in libcurl
Unfortunately at least one version of libcurl has a bug causing
it to include "Accept: */*" in the same POST request where we have
already asked for "Accept: application/x-git-upload-pack-response".
This is a bug in libcurl, not Git, or our test vector. The
application has explicitly asked the server for a single content
type, but libcurl has mistakenly also told the server the client
application will accept */*, which is any content type.
Based on the libcurl change log, this "Accept: */*" header bug
may have been fixed in version 7.18.1 released March 30, 2008:
http://curl.haxx.se/changes.html#7_18_1
Rather than require users to upgrade libcurl we change the test
vector to trim this line out of the 2nd request.

http-backend: Protect GIT_PROJECT_ROOT from /../ requests
Eons ago HPA taught git-daemon how to protect itself from /../
attacks, which Junio brought back into service in d79374c7b58d
("daemon.c and path.enter_repo(): revamp path validation").
I did not carry this into git-http-backend as originally we relied
only upon PATH_TRANSLATED, and assumed the HTTP server had done
its access control checks to validate the resolved path was within
a directory permitting access from the remote client. This would
usually be sufficient to protect a server from requests for its
/etc/passwd file by http://host/smart/../etc/passwd sorts of URLs.
However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an
additional method of configuring the CGI. When this environment
variable is used the web server does not generate the final access
path and therefore may blindly pass through "/../etc/passwd"
in PATH_INFO under the assumption that "/../" might have special
meaning to the invoked CGI.
Instead of permitting these sorts of malformed path requests, we
now reject them back at the client, with an error message for the
server log. This matches git-daemon behavior.

Once upon a time, format-patch would use its default stat
plus patch format only when no diff format was given on the
command line. This meant that "format-patch -p" would
suppress the stat and show just the patch.
Commit 68daa64 changed this to keep the stat format when we
had an "implicit" patch format, like "-U5". As a side
effect, this meant that an explicit patch format was now
ignored (because cmd_format_patch didn't know the reason
that the format was set way down in diff_opt_parse).
This patch unbreaks what 68daa64 did (while still preserving
what 68daa64 was trying to do), reinstating "-p" to suppress
the default behavior. We do this by parsing "-p" ourselves
in format-patch, and noting whether it was used explicitly.

with a run of "footer" lines, to cover S-o-b's friends, e.g. Acked-by.

t1200: prepare for merging with Fast-forward bikeshedding
A tree-wide bikeshedding to replace "fast forward" into "fast-forward" is

Sigh... This kind of headache is the primary reason we try not to allow
such a tree-wide bike-shedding, but the damage has already been done.
Instead of using bare "cmp", use "test_cmp". Output when the test is run
with a -v option becomes easier to diagnose when something goes wrong
because on saner platforms test_cmp uses "diff -u".
There is no need to put an extra backslash to a line that ends with a '|'

The top level directory "/smart/" of the test Apache server is mapped
through our git-http-backend CGI, but uses the same underlying
repository space as the server's document root. This is the most
simple installation possible.
Server logs are checked to verify the client has accessed only the
smart URLs during the test. During fetch testing the headers are
also logged from libcurl to ensure we are making a reasonably sane
HTTP request, and getting back reasonably sane response headers
from the CGI.
When validating the request headers used during smart fetch we munge
away the actual Content-Length and replace it with the placeholder
"xxx". This avoids unnecessary varability in the test caused by
an unrelated change in the requested capabilities in the first want
line of the request. However, we still want to look for and verify
that Content-Length was used, because smaller payloads should be
using Content-Length and not "Transfer-Encoding: chunked".
When validating the server response headers we must discard both
Content-Length and Transfer-Encoding, as Apache2 can use either
format to return our response.
During development of this test I observed Apache returning both
forms, depending on when the processes got CPU time. If our CGI
returned the pack data quickly, Apache just buffered the whole
thing and returned a Content-Length. If our CGI took just a bit
too long to complete, Apache flushed its buffer and instead used
"Transfer-Encoding: chunked".

The git-remote-curl backend detects if the remote server supports
the git-upload-pack service, and if so, runs git-fetch-pack locally
in a pipe to generate the want/have commands.
The advertisements from the server that were obtained during the
discovery are passed into git-fetch-pack before the POST request
starts, permitting server capability discovery and enablement.
Common objects that are discovered are appended onto the request as
have lines and are sent again on the next request. This allows the
remote side to reinitialize its in-memory list of common objects
during the next request.
Because all requests are relatively short, below git-remote-curl's
1 MiB buffer limit, requests will use the standard Content-Length
header and be valid HTTP/1.0 POST requests. This makes the fetch
client more tolerant of proxy servers which don't support HTTP/1.1
or the chunked transfer encoding.

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.

either line- or word- oriented diff output."
* introduce fn_out_consume_word_diff() that is "this is called every time
a line worth of diff becomes ready from the lower-level diff routine,

This patch is to at least abstract the details of "this totally different

We can later refactor it by introducing fn_out_consume_word_diff(), taking
the second route above, but that is a separate topic.
There is not enough justification for doing this. We do not update
things in .git/branches and .git/remotes anymore, but still do read
information from there and will keep doing so.
Besides, this breaks quite a lot of tests in t55?? series.

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.

Some transports, like the native pack transport implemented by
fetch-pack, support useful features like depth or include tags.
These should be exposed if the underlying helper knows how to
use them.

remote-helpers: Fetch more than one ref in a batch
Some network protocols (e.g. native git://) are able to fetch more
than one ref at a time and reduce the overall transfer cost by
combining the requests into a single exchange. Instead of feeding
each fetch request one at a time to the helper, feed all of them
at once so the helper can decide whether or not it should batch them.

fetch: Allow transport -v -v -v to set verbosity to 3
Helpers might want a higher level of verbosity than just +1 (the
porcelain default setting) and +2 (-v -v). Expand the field to
allow verbosity in the range -1..3.

We will need the walker, url and remote in other functions as the
code grows larger to support smart HTTP. Extract this out into a
set of globals we can easily reference once configured.

Add multi_ack_detailed capability to fetch-pack/upload-pack
When multi_ack_detailed is enabled the ACK continue messages returned
by the remote upload-pack are broken out to describe the different
states within the peer. This permits the client to better understand
the server's in-memory state.
The fetch-pack/upload-pack protocol now looks like:
NAK
---------------------------------
Always sent in response to "done" if there was no common base
selected from the "have" lines (or no have lines were sent).
* no multi_ack or multi_ack_detailed:
Sent when the client has sent a pkt-line flush ("0000") and
the server has not yet found a common base object.
* either multi_ack or multi_ack_detailed:
Always sent in response to a pkt-line flush.
ACK %s
-----------------------------------
* no multi_ack or multi_ack_detailed:
Sent in response to "have" when the object exists on the remote
side and is therefore an object in common between the peers.
The argument is the SHA-1 of the common object.
* either multi_ack or multi_ack_detailed:
Sent in response to "done" if there are common objects.
The argument is the last SHA-1 determined to be common.
The remote side wants the client to consider this object as
common, and immediately stop transmitting additional "have"
lines for objects that are reachable from it. The reason
the client should stop is not given, but is one of the two
cases below available under multi_ack_detailed.
ACK %s common
-----------------------------------
* multi_ack_detailed only:
Sent in response to "have". Both sides have this object.
Like with "ACK %s continue" above the client should stop
sending have lines reachable for objects from the argument.
The client should stop transmitting objects which are reachable
from the argument, and send "done" soon to get the objects.
If the remote side has the specified object, it should
first send an "ACK %s common" message prior to sending
"ACK %s ready".
Clients may still submit additional "have" lines if there are
more side branches for the client to explore that might be added
to the common set and reduce the number of objects to transfer.
