11031d7e9f add receive.denyNonFastforwards config variable
If receive.denyNonFastforwards is set to true, git-receive-pack will deny
non fast-forwards, i.e. forced updates. Most notably, a push to a repository
which has that flag set will fail.

As a first user, 'git-init-db --shared' sets this flag, since in a shared
setup, you are most unlikely to want forced pushes to succeed.

2d10c55537 git log: Unify header_filter and message_filter into one.
Now we can tell the built-in grep to grep only in head or in
body, use that to update --author, --committer, and --grep.

Unfortunately, to make --and, --not and other grep boolean
expressions useful, as in:

	# Things written by Junio committed and by Linus and log
	# does not talk about diff.

	git log --author=Junio --and --committer=Linus \
		--grep-not --grep=diff

we will need to do another round of built-in grep core
enhancement, because grep boolean expressions are designed to
work on one line at a time.

83b5d2f5b0 builtin-grep: make pieces of it available as library.
This makes three functions and associated option structures from
builtin-grep available from other parts of the system.

 * options to drive built-in grep engine is stored in struct
   grep_opt;

 * pattern strings and extended grep expressions are added to
   struct grep_opt with append_grep_pattern();

 * when finished calling append_grep_pattern(), call
   compile_grep_patterns() to prepare for execution;

 * call grep_buffer() to find matches in the in-core buffer.

This also adds an internal option "status_only" to grep_opt,
which suppresses any output from grep_buffer().  Callers of the
function as library can use it to check if there is a match
without producing any output.

cd90e75ff4 gitweb: Even more support for PATH_INFO based URLs
Now the following types of path based URLs are supported:

* project              overview (summary) page of project
* project/branch       shortlog of branch
* project/branch:file  file in branch, blob_plain view
* project/branch:dir/  directory listing of dir in branch, tree view

The following shortcuts works (see explanation below):

* project/branch:      directory listing of branch, main tree view
* project/:file        file in HEAD (raw)
* project/:dir/        directory listing of dir in HEAD
* project/:            directory listing of project's HEAD

We use ':' as separator between branch (ref) name and file name
(pathname) because valid branch (ref) name cannot have ':' inside.
This limit applies to branch name only. This allow for hierarchical
branches e.g. topic branch 'topic/subtopic', separate remotes
tracking branches e.g. 'refs/remotes/origin/HEAD', and discriminate
between head (branch) and tag with the same name.

Empty branch should be interpreted as HEAD.

If pathname (the part after ':') ends with '/', we assume that pathname
is name of directory, and we want to show contents of said directory
using "tree" view. If pathname is empty, it is equivalent to '/' (top
directory).

If pathname (the part after ':') does not end with '/', we assume that
pathname is name of file, and we show contents of said file using
"blob_plain" view.

Pathname is stripped of leading '/', so we can use ':/' to separate
branch from pathname. The rationale behind support for PATH_INFO based
URLs was to support project web pages for small projects: just create
an html branch and then use an URL like
  http://nowhere.com/gitweb.cgi/project.git/html:/index.html
The ':/' syntax allow for working links between .html files served
in such way, e.g. <a href="main.html"> link inside "index.html"
would get
  http://nowhere.com/gitweb.cgi/project.git/html:/main.html.

c774b2dcf6 Patch for http-fetch.c and older curl releases
Older curl releases do not define CURLE_HTTP_RETURNED_ERROR, they
use CURLE_HTTP_NOT_FOUND instead. Newer curl releases keep the
CURLE_HTTP_NOT_FOUND definition but using a -DCURL_NO_OLDIES

header.

This patch makes our code written for newer releases of the curl
library but allow compiling against an older curl (older than
0x070a03) by defining the missing CURLE_HTTP_RETURNED_ERROR as a
synonym for CURLE_HTTP_NOT_FOUND.

f2b5792564 Fix git-am safety checks
An earlier commit cbd64af added a check that prevents "git-am"
to run without its standard input connected to a terminal while
resuming operation.  This was to catch a user error to try
feeding a new patch from its standard input while recovery.

The assumption of the check was that it is an indication that a
new patch is being fed if the standard input is not connected to
a terminal.  It is however not quite correct (the standard input
can be /dev/null if the user knows the operation does not need
any input, for example).  This broke t3403 when the test was run
with its standard input connected to /dev/null.

When git-am is given an explicit command such as --skip, there
is no reason to insist that the standard input is a terminal; we
are not going to read a new patch anyway.

Credit goes to Gerrit Pape for noticing and reporting the
problem with t3403-rebase-skip test.

9c95fbf94f upload-archive: monitor child communication even more carefully.
The current code works like this: if others flags than POLLIN is
raised we assume that (a) something bad happened and the child died or
(b) the child has closed the pipe because it had no more data to send.

For the latter case, we assume wrongly that one call to
process_input() will empty the pipe. Indeed it reads only 16Ko of data
by call and the the pipe capacity can be larger than that (on current
Linux kernel, it is 65536 bytes). Therefore the child can write 32ko
of data, for example, and close the pipe. After that poll will return
POLLIN _and_ POLLHUP and the parent will read only 16ko of data.

This patch forces the parent to empty the pipe as soon as POLLIN is
raised and even if POLLHUP or something else is raised too.

Moreover, some implementations of poll might return POLLRDNORM flag
even if it is non standard.

This patch removes the custom tree walker tree_traverse(), and makes
generate_tar() use write_tar_archive() and the infrastructure provided
by git-archive instead.

As a kind of side effect, make write_tar_archive() able to handle NULL
as base directory, as this is what the new and simple generate_tar()
uses to indicate the absence of a base directory.  This was simpler
and cleaner than playing tricks with empty strings.

the plain file contents of some file contained in the repository.

This is especially useful to support project web pages for small

4be609625e apply --unidiff-zero: loosen sanity checks for --unidiff=0 patches
In "git-apply", we have a few sanity checks and heuristics that
expects that the patch fed to us is a unified diff with at least
one line of context.

 * When there is no leading context line in a hunk, the hunk
   must apply at the beginning of the preimage.  Similarly, no
   trailing context means that the hunk is anchored at the end.

 * We learn a patch deletes the file from a hunk that has no
   resulting line (i.e. all lines are prefixed with '-') if it
   has not otherwise been known if the patch deletes the file.
   Similarly, no old line means the file is being created.

And we declare an error condition when the file created by a
creation patch already exists, and/or when a deletion patch
still leaves content in the file.

These sanity checks are good safety measures, but breaks down
when people feed a diff generated with --unified=0.  This was
recently noticed first by Matthew Wilcox and Gerrit Pape.

This adds a new flag, --unified-zero, to allow bypassing these
checks.  If you are in control of the patch generation process,
you should not use --unified=0 patch and fix it up with this
flag; rather you should try work with a patch with context.  But
if all you have to work with is a patch without context, this
flag may come handy as the last resort.

a1565c447d gitweb: Allow for href() to be used for links without project param
Make it possible to use href() subroutine to generate link with
query string which does not include project ('p') parameter.
href() used to add project=$project to its parameters, if it
was not set (to be more exact if $params{'project'} was false).
Now you can pass "project => undef" if you don't want for href()
to add project parameter to query string in the generated link.

Links to "project_list", "project_index" and "opml" (all related
to list of all projects/all git repositories) doesn't need project
parameter. Moreover "project_list" is default view (action) if
project ('p') parameter is not set, just like "summary" is default
view (action) if project is set; project list served as a kind
of "home" page for gitweb instalation, and links to "project_list"
view were done without specyfying it as an action.

Convert remaining links (except $home_link and anchor links)
to use href(); this required adding 'order => "o"' to @mapping
in href(). This finishes consolidation of URL generation.
