Provide a DEFAULT_PAGER knob so packagers can set the fallback
pager to something appropriate during the build.
Examples:
On (old) solaris systems, /usr/bin/less (typically the first less
found) doesn't understand the default arguments (FXRS), which
forces users to alter their environment (PATH, GIT_PAGER, LESS,
etc) or have a local or global gitconfig before paging works as
expected.
On Debian systems, by policy packages must fall back to the
'pager' command, so that changing the target of the
/usr/bin/pager symlink changes the default pager for all packages
at once.

Refuse to use $VISUAL and fall back to $EDITOR if TERM is unset
or set to "dumb". Traditionally, VISUAL is set to a screen
editor and EDITOR to a line-based editor, which should be more
useful in that situation.
vim, for example, is happy to assume a terminal supports ANSI
sequences even if TERM is dumb (e.g., when running from a text
editor like Acme). git already refuses to fall back to vi on a
dumb terminal if GIT_EDITOR, core.editor, VISUAL, and EDITOR are
unset, but without this patch, that check is suppressed by

Since a0e4639 (filter-branch: fix ref rewriting with
--subdirectory-filter, 2008-08-12) git-filter-branch has done
nearest-ancestor rewriting when using a --subdirectory-filter.
However, that rewriting strategy is also a useful building block in
other tasks. For example, if you want to split out a subset of files
from your history, you would typically call
git filter-branch -- <refs> -- <files>
But this fails for all refs that do not point directly to a commit
that affects <files>, because their referenced commit will not be
rewritten and the ref remains untouched.
The code was already there for the --subdirectory-filter case, so just
introduce an option that enables it independently.

an extra '--' was used as path filter in the call to git-rev-list that
determines the commits that shall be rewritten.
To keep the argument handling sane, we filter $@ to contain only the
non-revision arguments, and store all revisions in $ref_args. The
$ref_args are easy to handle since only the SHA1s are needed; the
actual branch names have already been stored in $tempdir/heads at this
point.
An extra separating -- is only required if the user did not provide
any non-revision arguments, as the latter disambiguate the
$filter_subdir following after them (or fail earlier because they are
ambiguous themselves).
Thanks to Johannes Sixt for suggesting this solution.

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

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.

So I think it is okay if "show-ref -h" (but not "show-ref

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

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

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.

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
shortened to to 7 characters
* otherwise if 'h' / $hash parameter is tag name (it begins with
'refs/tags/' prefix, use tag name (with 'refs/tags/' stripped
* otherwise if 'h' / $hash parameter starts with 'refs/heads/' prefix,
strip this prefix, convert '/' into '.', and append shortened SHA-1
after '-', i.e. use <sanitized hash>-<shortened sha1>

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.

Once upon a time, format-patch would use its default stat

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

the default behavior. We do this by parsing "-p" ourselves

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

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 '|'

clients may access from the repository, or they just want to
encourage clients to use the more bandwidth efficient transport.
If http.getanyfile is set to false the backend CGI will return with
'403 Forbidden' when an object file is accessed by a dumb client.

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".

To clarify what part of the HTTP transprot is being tested we change
the URLs used by existing tests to include /dumb/ at the start,
indicating they use the non-Git aware code paths.

The upload-pack requests are mostly plain text and they compress
rather well. Deflating them with Content-Encoding: gzip can easily
drop the size of the request by 50%, reducing the amount of data
to transfer as we negotiate the common commits.

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.

Discover refs via smart HTTP server when available
Instead of loading the cached info/refs, try to use the smart HTTP
version when the server supports it. Since the smart variant is
actually the pkt-line stream from the start of either upload-pack
or receive-pack we need to parse these through get_remote_heads,
which requires a background thread to feed its pipe.
