64b1cb74f8 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.

548d3464dc Show usage string for 'git http-push -h'
http-push already knows how to dump usage if it is given no options, but
it interprets '-h' as the URL to a remote repository:

    $ git http-push -h
    error: Cannot access URL -h/, return code 6

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.

2cfa8330e4 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
'git format-patch'.

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.

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:

  --raw
  -z
  --color
  --no-color
  --color-words
  --diff-filter
  -S
  --pickaxe-all
  --pickaxe-regex

02bc5b03f5 format-patch: Always generate a patch
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.

This only changes the behavior of "git check-ref-format -h"

This change cannot be breaking backward compatibility, since any
valid refname must contain a /.   Most existing scripts use
arguments such as "heads/$foo".  If some script checks the
refname "-h" alone, git check-ref-format will still exit with
nonzero status, and the only detrimental side-effect will be a
usage string sent to stderr.

16679e373f Teach the --multiple option to 'git fetch'
Add the --multiple option to specify that all arguments are either
groups or remotes. The primary reason for adding this option is
to allow us to re-implement 'git remote update' using fetch.

It would have been nice if this option was not needed, but since
the colon in a refspec is optional, it is in general not possible
to know whether a single, colon-less argument is a remote or a
refspec.

9c4a036b34 Teach the --all option to 'git fetch'
'git remote' is meant for managing remotes and 'git fetch' is meant
for actually fetching data from remote repositories. Therefore, it is
not logical that you must use 'git remote update' to fetch from
more than one repository at once.

Add the --all option to 'git fetch', to tell it to attempt to fetch
from all remotes. Also, if --all is not given, the <repository>
argument is allowed to be the name of a group, to allow fetching
from all repositories in the group.

Other options except -v and -q are silently ignored.

e62b393505 Show usage string for 'git show-ref -h'
This only changes the behavior of "git show-ref -h" without any
other options and arguments.

"show-ref -h" currently is short for "show-ref --head", which
shows all the refs/* and HEAD, as opposed to "show-ref" that
shows all the refs/* and not HEAD.

Does anybody use "show-ref -h"?  It was in Linus's original, most
likely only because "it might be handy", not because "the command
should not show the HEAD by default for such and such reasons".
So I think it is okay if "show-ref -h" (but not "show-ref
--head") gives help and exits.

If a current script uses "git show-ref -h" without any other
arguments, it would have to be adapted by changing "-h" to
"--head".

203666352f 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.

34b6cb8bb0 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 d79374c7b5
("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 917adc0360 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.

b629275fd0 gitweb: Smarter snapshot names
Teach gitweb how to produce nicer snapshot names by only using the
short hash id.  If clients make requests using a tree-ish that is not
a partial or full SHA-1 hash, then the short hash will also be appended
to whatever they asked for.  If clients request snapshot of a tag
(which means that $hash ('h') parameter has 'refs/tags/' prefix),
use only tag name.

Update tests cases in t9502-gitweb-standalone-parse-output.

Gitweb uses the following format for snapshot filenames:
  <sanitized project name>-<version info>.<snapshot suffix>
where <sanitized project name> is project name with '.git' or '/.git'
suffix stripped, unless '.git' is the whole project name.  For
snapshot prefix it uses:
  <sanitized project name>-<version info>/
as compared to <sanitized project name>/ before (without version info).

Current rules for <version info>:
* if 'h' / $hash parameter is SHA-1 or shortened SHA-1, use SHA-1

3ce9450a81 gitweb: Document current snapshot rules via new tests
Add t9502-gitweb-standalone-parse-output test script, which runs
gitweb as a CGI script from the commandline and checks that it
produces the correct output.

Currently this test script contains only tests of snapshot naming
(proposed name of snapshot file) and snapshot prefix (prefix of files
in the archive / snapshot).  It defines and uses 'tar' snapshot
format, without compression, for easy checking of snapshot prefix.
Testing is done using check_snapshot function.

Gitweb uses the following format for snapshot filenames:
  <sanitized project name>-<hash parameter><snapshot suffix>
where <sanitized project name> is project name with '.git' or '/.git'
suffix stripped, unless '.git' is the whole project name.  For
snapshot prefix it uses simply:
  <sanitized project name>/

Disadvantages of current snapshot rules:
* There exists convention that <basename>.<suffix> archive unpacks to
  <basename>/ directory (<basename>/ is prefix of archive).  Gitweb
  does not respect it
* Snapshot links generated by gitweb use full SHA-1 id as a value of
  'h' / $hash parameter.  With current rules it leads to long file
  names like e.g. repo-1005c80cc11c531d327b12195027cbbb4ff9e3cb.tgz
* For handcrafted URLs, where 'h' / $hash parameter is a symbolic
  'volatile' revision name such as "HEAD" or "next" snapshot name
  doesn't tell us what exact version it was created from
* Proposed filename in Content-Disposition header should not contain
  any directory path information, which means that it should not
  contain '/' (see RFC2183)... which means that snapshot naming is
  broken for $hash being e.g. hirearchical branch name such as
  'xx/test'

This would be improved in next commit.

69a9cd31b1 Documentation: add "Fighting regressions with git bisect" article
This patch adds an asciidoc version of the "Fighting regressions with
git bisect" article that the author wrote for the Linux-Kongress
2009 (http://www.linux-kongress.org/2009).

This paper might be interesting to people who want to learn as much as
possible about "git bisect" from a single document.

The slides of the related presentation are available at:

http://www.linux-kongress.org/2009/slides/fighting_regressions_with_git_bisect_christian_couder.pdf

But the Linux Kongress people will not publish this paper online because
they print the papers on their UpTimes magazine
(http://www.lob.de/isbn/978-3-86541-358-1). But they don't take away the
rights of the author (which is very nice), so I have the right to publish
it.

b1b952043f MSVC: Add support for building with NO_MMAP
When the NO_MMAP build variable is set, the msvc linker complains:

    error LNK2001: unresolved external symbol _getpagesize

The msvc libraries do not define the getpagesize() function,
so we move the mingw_getpagesize() implementation from the
conditionally built win32mmap.c file to mingw.c.
