14569cd810 gitweb: Git config keys are case insensitive, make config search too
"git config -z -l" that gitweb uses in git_parse_project_config() to
populate %config hash returns section and key names of config
variables in lowercase (they are case insensitive).  When checking
%config in git_get_project_config() we have to take it into account.

131d6afcba gitweb: Introduce common system-wide settings for convenience
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

e8c3531717 gitweb: Serve */*+xml 'blob_plain' as text/plain with $prevent_xss
Enhance usability of 'blob_plain' view protection against XSS attacks
(enabled by setting $prevent_xss to true) by serving contents inline
as safe 'text/plain' mimetype where possible, instead of serving with
"Content-Disposition: attachment" to make sure they don't run in
gitweb's security domain.

This patch broadens downgrading to 'text/plain' further, to any
*/*+xml mimetype.  This includes:

  application/xhtml+xml    (*.xhtml, *.xht)
  application/atom+xml     (*.atom)
  application/rss+xml      (*.rss)
  application/mathml+xm    (*.mathml)
  application/docbook+xml  (*.docbook)
  image/svg+xml            (*.svg, *.svgz)

Probably most useful is serving XHTML files as text/plain in
'blob_plain' view, directly viewable.

Because file with 'image/svg+xml' mimetype can be compressed SVGZ
file, we have to check if */*+xml really is text file, via '-T $fd'.

86afbd02c8 gitweb: Serve text/* 'blob_plain' as text/plain with $prevent_xss
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.

Extract the following parts into separate subroutines:

 * finding correct MIME content type for HTML pages (text/html or
   application/xhtml+xml?) into get_content_type_html()
 * printing <link ...> elements in HTML head into print_header_links()
 * printing navigation "breadcrumbs" for given action into
   print_nav_breadcrumbs()
 * printing search form into print_search_form()

This reduces git_header_html to two pages long (53 lines), making gitweb

1ae05be4aa gitweb: Make git_search_* subroutines render whole pages
Move git_header_html() and git_footer_html() invocation from git_search()
to individual git_search_* subroutines.

While at it, reorganize search-related code a bit, moving invoking of git
commands before any output is generated.

This has the following advantages:

  * gitweb now shows an error page if there was unknown search type
    (evaluate_and_validate_params checks only that it looks sanely);
    remember that we shouldn't call die_error after any output.

  * git_search_message is now safe agains die_error in parse_commits
    (though this is very unlikely).

  * gitweb now can check errors while invoking git commands and show
    error page (again, quite unlikely).

2c162b56f3 gitweb: do not misparse nonnumeric content tag files that contain a digit
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
^\d+$.

42ab5d40de gitweb.js: use setTimeout rather than setInterval in blame_incremental.js
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).

JavaScript is single-threaded, so there is no need for protection
against re-entrancy via inProgress variable.

In particular calls to setInterval handler are stacked if handler
doesn't finish before new interrupt (before new interval).  The same
happens with events - they are (hopefully) stacked if even handler
didn't finish work.

2e987f9240 gitweb: Make JavaScript ability to adjust timezones configurable
Configure JavaScript-based ability to select common timezone for git
dates via %feature mechanism, namely 'javascript-timezone' feature.

The following settings are configurable:
* default timezone (defaults to 'local' i.e. browser timezone);
  this also can function as a way to disable this ability,
  by setting it to false-ish value (undef or '')
* name of cookie to store user's choice of timezone
* class name to mark dates

NOTE: This is a bit of abuse of %feature system, which can store only
sequence of values, rather than dictionary (hash); usually but not
always only a single value is used.

2ae8da2552 gitweb.js: Add UI for selecting common timezone to display dates
This will modify HTML, add CSS rules and add DOM event handlers so
that clicking on any date (the common part, not the localtime part)
will display a drop down menu to choose the timezone to change to.

Currently menu displays only the following timezones:

  utc
  local
  -1200
  -1100
  ...
  +1100
  +1200
  +1300
  +1400

In timezone selection menu each timezone is +1hr to the previous.  The
code is capable of handling fractional timezones, but those have not
been added to the menu.

All changes are saved to a cookie, so page changes and closing /
reopening browser retains the last known timezone setting used.

[jn: Changed from innerHTML to DOM, moved to event delegation for
onclick to trigger menu, added close button and cookie refreshing]

291e52bd19 gitweb: JavaScript ability to adjust time based on timezone
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

This means that both 'summary' and 'log' views now display localtime.

now one can easily see which commits in a series are made "atnight"

54b1479a77 gitweb.js: Extract and improve datetime handling
Move formatDateISOLocal(epoch, timezone) function (and also helper
timezoneOffset(timezoneInfo) function it requires) from common-lib.js to
datetime.js

Add new functions:
* localTimezoneOffset - to get browser timezone offset in seconds
* localTimezoneInfo   - to get browser timezone in '(+|-)HHMM' format
* formatTimezoneInfo - turn offset in hours and minutes into '(+|-)HHMM'
* parseRFC2822Date - to parse RFC-2822 dates that gitweb uses into epoch
* formatDateRFC2882 - like formatDateISOLocal, only RFC-2822 format

All those functions are meant to be used in future commit
'gitweb: javascript ability to adjust time based on timezone'

An alternative would be to use e.g. Datejs (http://www.datejs.com)
library, or JavaScript framework that has date formatting (perhaps as
a plugin).

While at it escape '-' in character class inside tzRe regexp, as
recommended by JSLint (http://www.jslint.com).

4dfa207eec gitweb.js: Provide default values for padding in padLeftStr and padLeft
This means that one can use padLeft(4, 2) and it would be equivalent
to runing padLeft(4, 2, '0'), and it would return '04' i.e. '4' padded
with '0' to width 2, to be used e.g. in formatting date and time.

This should make those functions easier to use.  Current code doesn't
yet make use of this feature.

e2895de4d8 gitweb.js: Update and improve comments in JavaScript files
This consists of adding a few extra explanation, fixing descriptions
of functions to match names of parameters in code, adding a few
separators, and fixing spelling -- while at it spell 'neighbor' using
American spelling (and not as 'neighbour').

This is post-split cleanup.

9a86dd5710 gitweb: Split JavaScript for maintability, combining on build
Split originally single gitweb.js file into smaller files, each
dealing with single issue / area of responsibility.  This move should
make gitweb's JavaScript code easier to maintain.

For better webapp performance it is recommended[1][2][3] to combine
JavaScript files.  Do it during build time (in gitweb/Makefile), by
straight concatenation of files into gitweb.js file (which is now
ignored as being generated).  This means that there are no changes to
gitweb script itself - it still uses gitweb.js or gitweb.min.js, but
now generated.

d940c9015d gitweb: Optional grouping of projects by category
This adds the $projects_list_group_categories option which, if enabled,
will result in grouping projects by category on the project list page.
The category is specified for each project by the $GIT_DIR/category file
or the 'gitweb.category' variable in its configuration file. By default,
projects are put in the $project_list_default_category category.

Note:
- Categories are always sorted alphabetically, with projects in
  each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
  category headers are only displayed for projects present on the page.

The feature is inspired from Sham Chukoury's patch for the XMMS2
gitweb, but has been rewritten for the current gitweb code. The CSS
for categories is inspired from Gustavo Sverzut Barbieri's patch to
group projects by path.

Thanks to Florian Ragwitz for Perl tips.

[jn: Updated to post restructuring projects list generation, fixed bugs,
 added very basic test in t9500 that there are no warnings from Perl.]

4b9447f98e gitweb: Mark matched 'ctag' / contents tag (?by_tag=foo)
It might have been hard to discover that current view is limited to
projects with given content tag (ctag), as it was distinquished only
in gitweb URL.  Mark matched contents tag in the tag cloud using
"match" class, for easier discovery.

This commit introduces a bit of further code duplication in
git_populate_project_tagcloud().

e4e3b32bd2 gitweb: Modularized git_get_project_description to be more generic
Introduce a git_get_file_or_project_config utility function to
retrieve a repository variable either from a plain text file in the
$GIT_DIR or else from 'gitweb.$variable' in the repository config
(e.g. 'description').

This would be used in next commit to retrieve category for a project,
which is to be stored in the same way as project description.

0368c492d6 gitweb: Change the way "content tags" ('ctags') are handled
The major change is removing the ability to edit content tags (ctags)
in a web browser.

The interface was created by gitweb, while actual editing of tags was
to be done by external script; the API was not defined, and neither
was provided example implementation.  Such split is also a bit fragile
- interface and implementation have to be kept in sync.  Gitweb
provided only ability to add tags; you could not edit tags nor delete
them.

Format of ctags is now described in the comment above git_get_project_ctags
subroutine.  Gitweb now is more robust with respect to original ctags
format; it also accepts two new formats: $GIT_DIR/ctags file, with one
content tag per line, and multi-value `gitweb.ctag' config variable.

Gathering all ctags of all project is now put in git_gather_all_ctags
subroutine, making git_project_list_body more clear.

git_populate_project_tagcloud subroutine now generates data used for
tag cloud, including generation of ctag link, also in the case
HTML::TagCloud module is unavailable.  Links are now generated using
href() subroutine - this is more robust, as ctags might contain '?',
';' and '=' special characters that need to be escaped in query param.
Shown tags are HTML-escaped.

The generation of tag cloud in git_show_project_tagcloud in the case
when HTML::TagCloud is not available is now changed slightly.

The 'content tags' field on project summary page is made more in line
with other fields in "projects_list" table.  Because one cannot now
add new tags from web interface, this field is no longer displayed
when there are no content tags for given project.

0fa920c35c gitweb: Split git_project_list_body in two functions
Extract the printing of project rows (body/contents of projects list
table) on the 'project_list' page into a separate git_project_list_rows
function. This makes it easier to reuse the code to print different
subsets of the whole project list.

12b1443c2c gitweb: Restructure projects list generation
Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.

Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects.  Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.

Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed).  Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.

Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.

The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results).  If 'ctags' feature is disabled, then searching by tag is
too.

The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.

Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.

While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.
