Gitweb links to a number of static files such as CSS stylesheets,
favicon or the git logo. When, such as with the default Makefile, the
paths to these files are relative (i.e. doesn't start with a "/"), the
files become inaccessible in any view other tha project list and summary
page if gitweb is invoked with a non-empty PATH_INFO.
Fix this by adding a <base> element pointing to the script's own URL,
which ensure that all relative paths will be resolved correctly.

The output of commitdiff_plain is not intended for git-am:
* when given a range of commits, commitdiff_plain publishes a single
patch with the message from the first commit, instead of a patchset
* the hand-built email format replicates the commit summary both as
email subject and as first line of the email itself, resulting in
a duplication if the output is used with git-am.
We thus create a new view that can be fed to git-am directly, allowing
patch exchange via gitweb. The new view exposes the output of git
format-patch directly, limiting it to a single patch in the case of a
single commit.
A configurable upper limit defaulting to 16 is imposed on the number of
commits which will be included in a patchset, to prevent DoS attacks on
the server. Setting the limit to 0 will disable the patch view, setting
it to a negative number will remove the limit.

Luben Tuikov changed 'lineno' link from leading to commit which gave
current version of given block of lines, to leading to parent of this
commit in 244a70e (Blame "linenr" link jumps to previous state at
"orig_lineno"). This made possible data mining using 'blame' view.
The current implementation calls rev-parse once per each blamed line
to find parent revision of blamed commit, even when the same commit
appears more than once, which is inefficient.
This patch mitigates this issue by caching $parent_commit info in
%metainfo, which makes gitweb call rev-parse only once per each
unique commit in the output from "git blame".
In the tables below you can see simple benchmark comparing gitweb
performance before and after this patch

As you can see the greater ratio of lines in file to unique commits
in blame output, the greater gain from the new implementation.
Legend:
[1] Number of lines:
$ wc -l <file>
[2] Number of unique commits in the blame output:
$ git blame -p <file> | grep author-time | wc -l
[3] Time for running "git blame -p" (user time, single run):
$ time git blame -p <file> >/dev/null
[4] Time to run gitweb as Perl script from command line:
$ gitweb-run.sh "p=.git;a=blame;f=<file>" > /dev/null 2>&1
The gitweb-run.sh script includes slightly modified (with adjusted
pathnames) code from gitweb_run() function from the test script
t/t9500-gitweb-standalone-no-errors.sh; gitweb config file
gitweb_config.perl contents (again up to adjusting pathnames; in
particular $projectroot variable should point to top directory of git
repository) can be found in the same place.
Discussion
~~~~~~~~~~
A possible future improvement would be to open a bidi pipe to
"git cat-file --batch-check", (like in Git::Repo in gitweb caching by
Lea Wiemann), feed $long_rev^ to it, and parse its output, which is
in the following form:
926b07e694599d86cec668475071b32147c95034 commit 637
This would mean one call to git-cat-file for the whole 'blame' view,
instead of one call to git-rev-parse per each unique commit in blame
output.
Yet another solution would be to change use of validate_refname() to
validate_revision() when checking script parameters (CGI query or
path_info), with validate_revision being something like the following:
sub validate_revision {
my $rev = shift;
return validate_refname(strip_rev_suffixes($rev));
}
so we don't need to calculate $long_rev^, but can pass "$long_rev^" as
'hb' parameter.
This solution has the advantage that it can be easily adapted to future
incremental blame output.

Use new insert_file() subroutine to insert HTML chunks from external
files: $site_header, $home_text (by default indextext.html),
$site_footer, and $projectroot/$project/REAME.html.
All non-ASCII chars of those files will be broken by Perl IO layer
without decoding to utf8, so insert_file() does to_utf8() on each
printed line; alternate solution would be to open those files with
"binmode $fh, ':utf8'", or even all files with "use open qw(:std :utf8)".
Note that inserting README.html lost one of checks for simplicity.

The gitweb_get_feature() function retrieves the configuration parameters
for the feature (such as the list of snapshot formats or the list of
additional actions), but it is very often used to see if feature is
enabled (which is returned as the first element in the list).
Because accepting the returned list in the scalar context by mistake
yields the number of elements in the array, which is non-zero in all
cases, such a mistake would result in a bug for the latter use, with
disabled features appearing enabled. All existing callers that call the
function for this purpose assign the return value in the list context to
retrieve the first element, but that is only because we fixed careless
callers recently.
This adds gitweb_check_feature() as a wrapper to gitweb_get_feature() that
can be called safely in the scalar context to see if a feature is enabled
to reduce the risk of future bugs. Callers of "get" that use the call
only to see if the feature is enabled are updated to call this wrapper.

ModPerl::Registry precompiles scripts by wrapping them
in a subroutine. This causes ordinary subroutines of the
script to become nested, and warnings appear:
gitweb.cgi: Variable "$path_info" will not stay shared
This warning means that $path_info was declared as 'my',
and thus according to the perl evaluation rules all nested
subroutines will retain a reference to the instance of the
variable used in the first invocation of the master script.
When the script (i.e. the master meta-subroutine) is executed
the second time, it will use a new instance, so the logic
breaks. To avoid this it is necessary to declare all global
variables as 'our', which places them at the package level.

We parse requests for $project/snapshot/$head.$sfx as equivalent to
$project/snapshot/$head?sf=$sfx, where $sfx is any of the known
(although not necessarily supported) snapshot formats (or its default
suffix).
The filename for the resulting package preserves the requested
extensions (so asking for a .tgz gives a .tgz, and asking for a .tar.gz
gives a .tar.gz), although for obvious reasons it doesn't preserve the
basename (git/snapshot/next.tgz returns a file names git-next.tgz).
This introduces a potential case for ambiguity if a project has a head
that ends with a snapshot-like suffix (.zip, .tgz, .tar.gz, etc) and the
sf CGI parameter is not present; however, gitweb only produces URLs with
the sf parameter currently, so this is only a potential issue for
