Previous commit make gitweb use esc_html_match_hl() to mark match in
the _whole_ description of a project when searching projects.
This commit makes gitweb highlight match in _shortened_ description,
based on match in whole description, using esc_html_match_hl_chopped()
subroutine.
If match is in removed (chopped) part, even partially, then trailing
"... " is highlighted.

Use esc_html_match_hl() from earlier commit to mark match in the
_whole_ description when searching projects.
Currently, with this commit, when searching projects there is always
shown full description of a project, and not a shortened one (like for
ordinary projects list view), even if the match is on project name and
not project description. Because we always show full description of a
project, and not possibly shortened name, there is no need for having
full description on mouseover via title attribute.
Showing full description when there is match on it is useful to avoid
situation where match is in shortened, invisible part. On the other
hand that makes project search different than projects list view; also
there can be problems with overly-long project descriptions.

Use esc_html_match_hl() introduced in previous commit to escape HTML
and mark match, using span element with 'match' class. Currently only
the 'path' part (i.e. the project name) is highlighted; match might be
on the project description. Highlighting match in description is left
for next commit.
The code makes use of the fact that defined $search_regexp means that
there was search going on.

The esc_html_match_hl() subroutine added in this commit will be used
to highlight *all* matches of given regexp, using 'match' class.
Ultimately it is to be used in all match highlighting, starting
with project search, which does not have it yet.
It uses the esc_html_hl_regions() subroutine, which is meant to
highlight in a given string a list of regions (given as a list of
[ beg, end ] pairs of positions in string), using HTML <span> element
with given class. It could probably be used in other places that
do highlighting of part of ready line, like highlighting of changes
in a diff (diff refinement highlighting).
Implementation and enhancement notes:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Currently esc_html_hl_regions() subroutine doesn't accept any
parameters, like esc_html() does. We might want for example to
pass nbsp=>1 to it.
It can easily be done with the following code:
my %opts = grep { ref($_) ne "ARRAY" } @sel;
@sel = grep { ref($_) eq "ARRAY" } @sel;
This allow adding parameters after or before regions, e.g.:
esc_html_hl_regions("foo bar", "mark", [ 0, 3 ], -nbsp => 1);
* esc_html_hl_regions() escapes like esc_html(); if we wanted to
highlight with esc_path(), we could pass subroutine reference
to now named esc_gen_hl_regions().
esc_html_hl_regions("foo bar", "mark", \&esc_path, [ 0, 3 ]);
Note that this way we can handle -nbsp=>1 case automatically,
e.g.
esc_html_hl_regions("foo bar", "mark",
sub { esc_html(@_, -nbsp=>1) },
[ 0, 3 ]);
* Alternate solution for highlighting region of a string would be to
use the idea that strings are to be HTML-escaped, and references to
scalars are HTML (like in the idea for generic committags).
This would require modifying gitweb code or esc_html to get list of
fragments, e.g.:
esc_html(\'<span class="mark">', 'foo', \'</span>', ' bar',
{ -nbsp => 1 });
or
esc_html([\'<span class="mark">', 'foo', \'</span>', ' bar'],
-nbsp=>1);
esc_html_match_hl() could be then simple wrapper around "match
formatter", e.g.
esc_html([ render_match_hl($str, $regexp) ], -nbsp=>1);

Before searching by some field the information we search for must be
filled in, but we do not have to fill other fields that are not
involved in the search.
To be able to request filling only specified fields,
fill_project_list_info() was enhanced in previous commit to take
additional parameters which specify part of projects info to fill.
This way we can limit doing expensive calculations (like running
git-for-each-ref to get 'age' / "Last changed" info) to doing those
only for projects which we will show as search results.
This commit actually uses this interface, changing gitweb code from
the following behavior
fill all project info on all projects
search projects
to behaving like this pseudocode
fill search fields on all projects
search projects
fill all project info on search results
With this commit the number of git commands used to generate search
results is 2*<matched projects> + 1, and depends on number of matched
projects rather than number of all projects (all repositories).
Note: this is 'git for-each-ref' to find last activity, and 'git config'
for each project, and 'git --version' once.
Example performance improvements, for search that selects 2
repositories out of 12 in total:
* Before (warm cache):
"This page took 0.867151 seconds and 27 git commands to generate."
* After (warm cache):
"This page took 0.673643 seconds and 5 git commands to generate."
Now imagine that they are 5 repositories out of 5000, and cold or
trashed cache case.

Commit ff7f218 (gitweb: Fix file links in "grep" search, 2012-01-05),
added $file_href variable, to reduce duplication and have the fix
applied in single place.
Unfortunately it made variable defined inside the loop, not taking into
account the fact that $file_href was set only if file changed.
Therefore for files with multiple matches $file_href was undefined for
second and subsequent matches.
Fix this bug by moving $file_href declaration outside loop.

In a repository whose HEAD points to an unborn branch with no commits,
"heads" view and "summary" view (which shows what is shown in "heads"
view) compared the object names of commits at the tip of branches with the
output from "git rev-parse HEAD", which caused comparison of a string with
undef and resulted in a warning in the server log.
This can happen if non-bare repository (with default 'master' branch)
is updated not via committing but by other means like push to it, or
Gerrit. It can happen also just after running "git checkout --orphan
<new branch>" but before creating any new commit on this branch.
Rewrite the comparison so that it also works when $head points at nothing;
in such a case, no branch can be "the current branch", add a test for it.
While at it, rename local variable $head to $head_at, as it points to
current commit rather than current branch name (HEAD contents).
The code still incorrectly shows all branches that point at the same
commit as what HEAD points as "the current branch", even when HEAD is
detached. Fixing this bug is outside the scope of this patch.

gitweb: move hard coded .git suffix out of git_get_projects_list
Gitweb forgot to turn query parameters into UTF-8. This results in a bug
that one cannot search for a string with characters outside US-ASCII. For
example searching for "Michał Kiedrowicz" (containing letter 'ł' - LATIN
SMALL LETTER L WITH STROKE, with Unicode codepoint U+0142, represented
with 0xc5 0x82 bytes in UTF-8 and percent-encoded as %C5%82) result in the
following incorrect data in search field
MichaÅ\202 Kiedrowicz
This is caused by CGI by default treating '0xc5 0x82' bytes as two
characters in Perl legacy encoding latin-1 (iso-8859-1), because 's'
query parameter is not processed explicitly as UTF-8 encoded string.
The solution used here follows "Using Unicode in a Perl CGI script"
article on http://www.lemoda.net/cgi/perl-unicode/index.html:
use CGI;
use Encode 'decode_utf8;
my $value = params('input');
$value = decode_utf8($value);
Decoding UTF-8 is done when filling %input_params hash and $path_info
variable; the former requires to move from explicit $cgi->param(<label>)
to $input_params{<name>} in a few places, which is a good idea anyway.
Also add -override=>1 parameter to $cgi->textfield() invocation in search
form. Otherwise CGI would use values from query string if it is present,
filling value from $cgi->param... without decode_utf8(). As we are using
value of appropriate parameter anyway, -override=>1 doesn't change the
situation but makes gitweb fill search field correctly.
We could simply use the '-utf8' pragma (via "use CGI '-utf8';") to solve
this, but according to CGI.pm documentation, it may cause problems with
POST requests containing binary files, and it requires CGI 3.31 (I think),
released with perl v5.8.9.

This commit changes the project listing views (project_list,
project_index and opml) to limit the output to only projects in a
subdirectory if the new optional parameter ?pf=directory name is
used.
The implementation of the filter reuses the implementation used for
the 'forks' action (i.e. listing all projects within that directory
from the projects list file (GITWEB_LIST) or only projects in the
given subdirectory of the project root directory without a projects
list file).
Reusing $project instead of adding a new parameter would have been
nicer from a UI point-of-view (including PATH_INFO support) but
would complicate the $project validating code that is currently
being used to ensure nothing is exported that should not be viewable.

Use of the filter option of git_get_projects_list is currently limited
to forks. It currently assumes the project belonging to the filter
directory was already validated to be visible in the project list.
To make it more generic add an optional argument to denote visibility
verification is still needed.
If there is a projects list file (GITWEB_LIST) only projects from
this list are returned anyway, so no more checks needed.
If there is no projects list file and the caller requests strict
checking (GITWEB_STRICT_EXPORT), do not jump directly to the
given directory but instead do a normal search and filter the
results instead.
The only effect of GITWEB_STRICT_EXPORT without GITWEB_LIST is to make
sure no project can be viewed without also be found starting from
project root. git_get_projects_list without this patch does not enforce
this but all callers only call it with a filter already checked this
way. With this parameter a caller can request this check if the filter
cannot be checked this way.

And the "$pfxlen + 1" is supposed to mean "the length of the prefix, plus

$pfxlen, this basically eats the first character of the path, and yields
"404 - No projects found".

e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding.,

Simple benchmark confirms that (old = 00f429a, new = this version):
old new

new 189% --
Unfortunately it made fallback mode of to_utf8 do not work... except
for default value 'latin1' of $fallback_encoding ('latin1' is Perl
native encoding), which is why it was not noticed for such long time.
utf8::valid(STRING) is an internal function that tests whether STRING
is in a _consistent state_ regarding UTF-8. It returns true is
well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held
as bytes (both these states are 'consistent'). For gitweb the second
option was true, as output from git commands is opened without ':utf8'
layer.
What made it work at all for STRING in 'latin1' encoding is the fact
that utf8:decode(STRING) turns on UTF-8 flag only if source string is
valid UTF-8 and contains multi-byte UTF-8 characters... and that if
string doesn't have UTF-8 flag set it is treated as in native Perl
encoding, i.e. 'latin1' / 'iso-8859-1' (unless native encoding it is
EBCDIC ;-)). It was ':utf8' layer that actually converted 'latin1'
(no UTF-8 flag == native == 'latin1) to 'utf8'.
Let's make use of the fact that utf8:decode(STRING) returns false if
STRING is invalid as UTF-8 to check whether to enable fallback mode.

This commits adds to support for showing "side-by-side" style diff.
Currently you have to hand-craft the URL; navigation for selecting
diff style is to be added in the next commit.
The diff output in unified format from "git diff-tree" is reorganized to
side-by-side style chunk by chunk with format_sidebyside_diff_chunk().
This reorganization requires knowledge about diff line classification,
so format_diff_line() was renamed to process_diff_line(), and changed to
return tuple (list) consisting of class of diff line and of
HTML-formatted (but not wrapped in <div class="diff ...">...</div>) diff
line. Wrapping is now done by caller, i.e. git_patchset_body().
Gitweb uses float+margin CSS-based layout for "side by side" diff.
You can specify style of diff with "ds" ('diff_style') query
parameter. Currently supported values are 'inline' and 'sidebyside';
the default is 'inline'.
Another solution would be to use "opt" ('extra_options') for that...
though current use of it in gitweb seems to suggest that "opt" is more
about passing extra options to underlying git commands, and "git diff"
doesn't support '--side-by-side' like GNU diff does, (yet?).

...foo?js=0#l199
were not recognized as having 'js' query parameter already.
2. The 'js' query parameter, in the form of either '?js=1' or ';js=1'
was appended at the end of URI, even if it included a fragment
(had a hash part). This lead to the incorrect links like this
...foo#l199?js=1
instead of adding query parameter as last part of query, but
before the fragment part, i.e.
...foo?js=1#l199

The current code, as is, passes control characters, such as form-feed
(^L) to highlight which then passes it through to the browser. User
agents (web browsers) that support 'application/xhtml+xml' usually
require that web pages declared as XHTML and with this mimetype are
well-formed XML. Unescaped control characters cannot appear within a
contents of a valid XML document.
This will cause the browser to display one of the following warnings:
* Safari v5.1 (6534.50) & Google Chrome v13.0.782.112:
This page contains the following errors:
error on line 657 at column 38: PCDATA invalid Char value 12
Below is a rendering of the page up to the first error.
* Mozilla Firefox 3.6.19 & Mozilla Firefox 5.0:
XML Parsing Error: not well-formed
Location:
http://path/to/git/repo/blah/blah
Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7
using arch/ia64/kernel/unwind.c from the Linux kernel.
When syntax highlighter is not used, control characters are replaced
by esc_html(), but with syntax highlighter they were passed through to
browser (to_utf8() doesn't remove control characters).
Introduce sanitize() subroutine which strips forbidden characters, but
does not perform HTML escaping, and use it in git_blob() to sanitize
syntax highlighter output for XHTML.
Note that excluding "\t" (U+0009), "\n" (U+000A) and "\r" (U+000D) is
not strictly necessary, atleast for currently the only callsite: "\t"
tabs are replaced by spaces by untabify(), "\n" is stripped from each
line before processing it, and replacing "\r" could be considered
improvement.

Because of backward compatibility we cannot change gitweb to always
use /etc/gitweb.conf (i.e. even if gitweb_config.perl exists). For
common system-wide settings we therefore need separate configuration
file: /etc/gitweb-common.conf.
Long description:
gitweb currently obtains configuration from the following sources:
1. per-instance configuration file (default: gitweb_conf.perl)
2. system-wide configuration file (default: /etc/gitweb.conf)
If per-instance configuration file exists, then system-wide
configuration is _not used at all_. This is quite untypical and
suprising behavior.
Moreover it is different from way git itself treats /etc/git.conf. It
reads in stuff from /etc/git.conf and then local repos can change or
override things as needed. In fact this is quite beneficial, because
it gives site admins a simple and easy way to give an automatic hint
to a repo about things the admin would like.
On the other hand changing current behavior may lead to the situation,
where something in /etc/gitweb.conf may interfere with unintended
interaction in the local repository. One solution would be to
_require_ to do explicit include; with read_config_file() it is now
easy, as described in gitweb/README (description introduced in this
commit).
But as J.H. noticed we cannot ask people to modify their per-instance
gitweb config file to include system-wide settings, nor we can require
them to do this.
Therefore, as proposed by Junio, for gitweb to have centralized config
elements while retaining backwards compatibility, introduce separate
common system-wide configuration file, by default /etc/gitweb-common.conf

This patch broadens downgrading to 'text/plain' further, to any

application/mathml+xm (*.mathml)
application/docbook+xml (*.docbook)

Probably most useful is serving XHTML files as text/plain in

Because file with 'image/svg+xml' mimetype can be compressed SVGZ

One of mechanism enabled by setting $prevent_xss to true is 'blob_plain'
view protection. With XSS prevention on, blobs of all types except a
few known safe ones are served with "Content-Disposition: attachment" to
make sure they don't run in our security domain.
Instead of serving text/* type files, except text/plain (and including
text/html), as attachements, downgrade it to text/plain. This way HTML
pages in 'blob_plain' (raw) view would be displayed in browser, but
safely as a source, and not asked to be saved.

v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are
handled, 2011-04-29) tried to make gitweb's tag cloud feature more
intuitive for webmasters by checking whether the ctags/<label> under
a project's .git dir contains a number (representing the strength of
association to <label>) before treating it as one.
With that change, after putting '$feature{'ctags'}{'default'} = [1];'
in your $GITWEB_CONFIG, you could do
echo Linux >.git/ctags/linux
and gitweb would treat that as a request to tag the current repository
with the Linux tag, instead of the previous behavior of writing an
error page embedded in the projects list that triggers error messages
from Chromium and Firefox about malformed XML.
Unfortunately the pattern (\d+) used to match numbers is too loose,
and the "XML declaration allowed only at the start of the document"
error can still be experienced if you write "Linux-2.6" in place of
"Linux" in the example above. Fix it by tightening the pattern to

If there is a possibility that your logic could take longer to execute
than the interval time, it is recommended that you recursively call a
named function using window.setTimeout rather than window.setInterval.
Therefore instead of using setInterval as an alternate way of invoking
handleResponse (because some web browsers call onreadystatechange only
once per each distinct state, and not for each server flush), use
setTimeout and reset it from handleResponse. As a bonus this allows
us to get rid of timer if it turns out that web browser calls
onreadystatechange on each server flush.
While at it get rid of `xhr' global variable, creating it instead as
local variable in startBlame and passing it as parameter, and of
`pollTimer' global variable, passing it as member of xhr object
(xhr.pollTimer).

This patch is based on Kevin Cernekee's <cernekee@gmail.com>
patch series entitled "gitweb: introduce localtime feature". While
Kevin's patch changed the server side output so that the timezone
was output from gitweb itself, this has a number of drawbacks, in
particular with respect to gitweb-caching.
This patch takes the same basic goal, display the appropriate times in
a given common timezone, and implements it in JavaScript. This
requires adding / using a new class, "datetime", to be able to find
elements to be adjusted from JavaScript. Appropriate dates are
wrapped in a span with this class.
Timezone to be used can be retrieved from "gitweb_tz" cookie, though
currently there is no way to set / manipulate this cookie from gitweb;
this is left for later commit.
Valid timezones, currently, are: "utc", "local" (which means that
timezone is taken from browser), and "+/-ZZZZ" numeric timezone as in
RFC-2822. Default timezone is "local" (currently not configurable,
left for later commit).
Fallback (should JavaScript not be enabled) is to treat dates as they
have been and display them, only, in UTC.
Pages affected:
* 'summary' view, "last change" field (commit time from latest change)
* 'log' view, author time
* 'commit' and 'commitdiff' views, author/committer time
* 'tag' view, tagger time
