Jakub Narebski 6ee9033d67 gitweb: Refactor git_header_html
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
code easier to read.

Jakub Narebski 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).

Jonathan Nieder 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+$.

Jakub Narebski 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).

Jakub Narebski 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.

John 'Warthog9' Hawley 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]

John 'Warthog9' Hawley 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

Jakub Narebski 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.

Sebastien Cevey 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.

Sebastien Cevey 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.

Jakub Narebski 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.

Fraser Tweedale 0c8c385ef1 gitweb: supply '-n' to gzip for identical output
For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files.  Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.

Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems.  In particular, OpenBSD does not appear to
support it.

Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.

Jakub Narebski 2b1e17237b gitweb: Fix handling of fractional timezones in parse_date
Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.

This was caused by two mistakes:

* sign of timezone was applied only to hour part of offset, and not
  as it should be also to minutes part (this affected only negative
  fractional timezones).

* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
  so fractional part was discarded altogether ($h is hours, $m is
  minutes, which is always less than 60).

Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.

For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of
"Sat Jan 9 00:18:07 2010 +0530".

Kevin Cernekee 5e96a847b3 gitweb: fix #patchNN anchors when path_info is enabled
When $feature{'pathinfo'} is used, gitweb script sets the base URL to
itself, so that relative links to static files work correctly.  It
does it by adding something like below to HTML head:

  <base href="http://HOST/gitweb.cgi">

This breaks the "patch" anchor links seen on the commitdiff pages,
because these links, being relative (<a href="#patch1">), are resolved
(computed) relative to the base URL and not relative to current URL,
i.e. as:

  http://HOST/gitweb.cgi#patch1

Instead, they should look like this:

  35a9811ef9 (patch1)

Add an "-anchor" parameter to href(), and use href(-anchor=>"patch1")
to generate "patch" anchor links, so that the full path is included in
the patch link.

While at it, convert

  print "foo";
  print "bar";

to

  print "foo" .
        "bar";

in the neighborhood of changes.

Kevin Cernekee 6affdbe677 gitweb: highlight: replace tabs with spaces
Consider the following code fragment:

        /*
         * test
         */

vim ":set list" mode shows that the first character on each line is a
tab:

^I/*$
^I * test$
^I */$

By default, the "highlight" program will retain the tabs in the HTML
output:

$ highlight --fragment --syntax c test.c
        <span class="hl com">/*</span>
<span class="hl com">    * test</span>
<span class="hl com">    */</span>

vim list mode:

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

   1         /*
   2     * test
   3     */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

   1         /*
   2          * test
   3          */

This can be accomplished by specifying "--replace-tabs=8" on the
highlight command line.

Sylvain Rabot 3ca7353cab gitweb: remove unnecessary test when closing file descriptor
It happens that closing file descriptor fails whereas the blob is
perfectly readable.  According to perlman the reasons could be:

   If the file handle came from a piped open, "close" will additionally
   return false if one of the other system calls involved fails, or if the
   program exits with non-zero status.  (If the only problem was that the
   program exited non-zero, $! will be set to 0.)  Closing a pipe also waits
   for the process executing on the pipe to complete, in case you want to
   look at the output of the pipe afterwards, and implicitly puts the exit
   status value of that command into $?.

   Prematurely closing the read end of a pipe (i.e. before the process writ-
   ing to it at the other end has closed it) will result in a SIGPIPE being
   delivered to the writer.  If the other end can't handle that, be sure to
   read all the data before closing the pipe.

In this case we don't mind that close fails.

This fixes the issue with pathnames with embedded whitespace and

introduced esc_path_info() instead of esc_url() in href() subroutine.

Also while links are more clear not escaping space (' ') characters in

get discarded.

Jakub Narebski da4b2432cc gitweb: selectable configurations that change with each request
Allow selecting whether configuration file should be (re)parsed on each
request (the default, for backward compatibility with configurations that
change per session, see commit 7f425db (gitweb: allow configurations that
change with each request, 2010-07-30)), or whether should it be parsed only
once (for performance speedup for persistent environments, though currently
only FastCGI is able to make use of it, when flexibility is not important).

You can also have configuration file parsed only once, but have parts of
configuration (re)evaluated once per each request.

This is done by introducing $per_request_config variable: if set to code
reference, this code would be run once per request, while config file would
be parsed only once.  For example gitolite's contrib/gitweb/gitweb.conf
fragment mentioned in 7f425db could be rewritten as

  our $per_request_config = sub {
  	$ENV{GL_USER} = ($cgi && $cgi->remote_user) || "gitweb";
  };

to make use of this feature.

If $per_request_config is not a code reference, it is taken to be boolean
variable, to choose between running config file for each request
(flexibility), and running config file only once (performance in
persistent environments).

The default value for $per_request_config is 1 (true), which means that
old configuration that require to change per session (like gitolite's)
will keep working.

While at it, make it so evaluate_git_version() is run only once.

Jakub Narebski d0af3734f1 gitweb: Improve behavior for actionless path_info gitweb URLs
Eli Barzilay noticed that

  http://server/gitweb/project/<commit-sha1>

link goes to 'shortlog' view, while 'commit' view would be more
useful, but that 'shortlog' action is more apropriate for

  http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

links.

Therefore for the case when we don't have either action, or filename,
or parent hash [base] in path_info-based URL, i.e. for

  http://server/gitweb/project/<object-id>

link, instead of using 'shortlog' view we allow dispatch() subroutine
to detect type of object and use appropriate action (in most case it
would be either 'commit' action, or 'tag', or 'tree' for top
directory).

Now evaluate_git_version() is inside run_request() to be called for each
request, instead of once per starting gitweb; this currently matters only
when using FastCGI interface (gitweb.fcgi).

This change was done because evaluate_git_version() uses $GIT variable,
which can be set / modified by gitweb config file, but the variable is
modified this way by gitweb config file used in gitweb tests.  Without
this change there is spurious extra output from t9500 test when tests are

Ævar Arnfjörð Bjarmason d48b284183 perl: bump the required Perl version to 5.8 from 5.6.[21]
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.

However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:

    sub run_cmd_pipe {
           my $fh = undef;
           open($fh, '-|', @_) or die;
           return <$fh>;
    }

Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):

    t2016-checkout-patch.sh
    t3904-stash-patch.sh
    t3701-add-interactive.sh
    t7105-reset-patch.sh
    t7501-commit.sh
    t9700-perl-git.sh

Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.

The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.

All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

When searching commits for a string that never occurs, the results
page looks something like this:

	summary | ... | tree          [commit] search: [ kfjdkas ] [ ]re
	first ⋅ prev ⋅ next

	Merge branch 'maint'

	Foo: a demonstration project

Without a list of hits to compare it to, the header describing the
commit named by the hash parameter (usually HEAD) may itself look
like a hit.  Add some text (“No match.”) to replace the empty
list of hits and avoid this confusion.

While at it, remove some nearby dead code, left behind from a
simplification a few years ago (v1.5.4-rc0~276^2~4, 2007-11-01).

gitolite's contrib/gitweb/gitweb.conf includes:

	$ENV{GL_USER} = $cgi->remote_user || "gitweb";

which is useful for setups where a user has to be authenticated
to access certain repos.  Perhaps other typical configurations
change per session in other ways, too.

v1.7.2-rc2~6 (gitweb: Move evaluate_gitweb_config out of run_request,
2010-07-05) broke such configurations for a speedup, by loading
the configuration once per FastCGI process.

Probably in the end there should be a way to specify in the
configuration whether a particular installation wants the speedup or
the flexibility.  But for now it is easier to just undo the relevant
change.

This partially reverts commit 869d58813b.

Move evaluate_gitweb_config() and evaluate_git_version() out of
run_request() to run(), making them not run one for each request.
This changes how git behaves in FastCGI case.

This change makes it impossible to have config which changes with
request, but I don't think anyone relied on such (hidden action)
behavior.

While at it, reset timer and number of git commands at beginning of
run_request() in new reset_timer() subroutine.  This fixes case when
gitweb was run using FastCGI interface: time is reported for request,
and not for single run of gitweb script.  This changes slightly
behavior in non-FastCGI case: the number of git commands reported is
1 less (running `git --version` one per gitweb is not counted now).

Jakub Narebski c2394fe934 gitweb: Put all per-connection code in run() subroutine
All code that is run per-connection (as opposed to those parts of gitweb
code that can be run once) is put into appropriate subroutines:
 - evaluate_uri
 - evaluate_gitweb_config
 - evaluate_git_version (here only because $GIT can be set in config)
 - check_loadavg (as soon as possible; $git_version must be defined)
 - evaluate_query_params (counterpart to evaluate_path_info)
 - evaluate_and_validate_params
 - evaluate_git_dir (requires $project)
 - configure_gitweb_features (@snapshot_fmts, $git_avatar)
 - dispatch (includes setting default $action)

The difference is best viewed with '-w', '--ignore-all-space' option,
because of reindent caused by putting code in subroutines.

Jakub Narebski 592ea4173a gitweb: Refactor syntax highlighting support
This refactoring (adding guess_file_syntax and run_highlighter
subroutines) is meant to make it easier in the future to add support

Instead of looping over list of regexps (keys of %highlight_type hash),
make use of the fact that choosing syntax is based either on full
basename (%highlight_basename), or on file extension (%highlight_ext).

Jakub Narebski 7a59745710 gitweb: Add custom error handler using die_error
Change the default message for errors (for fatalsToBrowser) to use
die_error() subroutine.  This way errors (and explicitely calling 'die
MESSAGE') would generate 'Internal Server Error' error message.

Note that call to set_message is intentionally not put in BEGIN block;
we set error handler to use die_error() only after we are sure that we
can use it, after all needed variables are set.

Due to the fact that error handler set via set_message() subroutine
from CGI::Carp (in the fatalsToBrowser case) is called after HTTP
headers were already printed (with exception of MOD_PERL), gitweb
cannot return 'Status: 500 Internal Server Error'.

Thanks to the fact that die_error() no longer uses 'exit', errors
would be logged by CGI::Carp, independent on whether default error
handler is used, or handle_errors_html which uses die_error is used.

The build system added support minifying gitweb.js through a
JavaScript minifier, but most minifiers come with support for
minifying CSS files as well, so we should use it if we can.

This patch will add the same facilities to gitweb.css that
gitweb.js has for minification. That does not mean that they
will use the same minifier though, as it is not safe to assume
that all JavaScript minifiers will also minify CSS files.

This patch also adds the GITWEB_PROGRAMS variable to the Makefile
to keep a list of potential gitweb dependencies separate from
OTHER_PROGRAMS when we need to know just the gitweb dependencies.

Though the bandwidth savings will not be as dramatic as with
the JavaScript minifier, every byte saved is important.

Jakub Narebski 9be3614eff gitweb: Fix project-specific feature override behavior
This commit fixes a bug in processing project-specific override in
a situation when there is no project, e.g. for the projects list page.

When 'snapshot' feature had project specific config override enabled
by putting
  $feature{'snapshot'}{'override'} = 1;

(or equivalent) in $GITWEB_CONFIG, and when viewing toplevel gitweb
page, which means the projects list page (to be more exact this
happens for any project-less action), gitweb would put the following
Perl warnings in error log:

  gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2065.
  fatal: error processing config file(s)
  gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2221.
  gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2218.

The problem is in the following fragment of code:

  # path to the current git repository
  our $git_dir;
  $git_dir = "$projectroot/$project" if $project;

  # list of supported snapshot formats
  our @snapshot_fmts = gitweb_get_feature('snapshot');
  @snapshot_fmts = filter_snapshot_fmts(@snapshot_fmts);

For the toplevel gitweb page, which is the list of projects, $project is not
defined, therefore neither is $git_dir.  gitweb_get_feature() subroutine
calls git_get_project_config() if project specific override is turned
on... but we don't have project here.

Those errors mentioned above occur in the following fragment of code in
git_get_project_config():

  	# get config
  	if (!defined $config_file ||
  	    $config_file ne "$git_dir/config") {
  		%config = git_parse_project_config('gitweb');
  		$config_file = "$git_dir/config";
  	}

git_parse_project_config() calls git_cmd() which has '--git-dir='.$git_dir

There are (at least) three possible solutions:
1. Harden gitweb_get_feature() so that it doesn't call
   git_get_project_config() if $project (and therefore $git_dir) is not
   defined; there is no project for project specific config.
2. Harden git_get_project_config() like you did in your fix, returning early
   if $git_dir is not defined.
3. Harden git_cmd() so that it doesn't add "--git-dir=$git_dir" if $git_dir
   is not defined, and change git_get_project_config() so that it doesn't
   even try to access $git_dir if it is not defined.

This commit implements both 1.) and 2.), i.e. gitweb_get_feature() doesn't
call project-specific override if $git_dir is not defined (if there is no
project), and git_get_project_config() returns early if $git_dir is not
defined.

Add a test for this bug to t/t9500-gitweb-standalone-no-errors.sh test.

If the box is overloaded, it basically returns a 503 Server Unavailable
until the load falls below the defined threshold.  This helps dramatically
if you have a box that's I/O bound, reaches a certain load and you
don't want gitweb, the I/O hog that it is, increasing the pain the
server is already undergoing.

This behavior is controlled by $maxload configuration variable.
Default is a load of 300, which for most cases should never be hit.
Unset it (set it to undefined value, i.e. undef) to turn off checking.

Currently it requires that '/proc/loadavg' file exists, otherwise the
load check is bypassed (load is taken to be 0).  So platforms that do
not implement '/proc/loadavg' currently cannot use this feature
(provisions are included for additional checks to be added by others).

There is simple test in t/t9501-gitweb-standalone-http-status.sh to
check that it correctly returns "503 Service Unavailable" if load is
too high, and also if there are any Perl warnings or errors.

Jakub Narebski b2c2e4c22c gitweb.js: Workaround for IE8 bug
In Internet Explorer 8 (IE8) the 'blame_incremental' view, which uses
JavaScript to generate blame info using AJAX, sometimes hang at the
beginning (at 0%) of blaming, e.g. for larger files with long history
like git's own gitweb/gitweb.perl.

The error shown by JavaScript console is "Unspecified error" at char:2
of the following line in gitweb/gitweb.js:

  if (xhr.readyState === 3 && xhr.status !== 200) {

Debugging it using IE8 JScript debuger shown that the error occurs
when trying to access xhr.status (xhr is XMLHttpRequest object).
Watch for xhr object shows 'Unspecified error.' as "value" of
xhr.status, and trying to access xhr.status from console throws error.

This bug is some intermittent bug, depending on XMLHttpRequest timing,
as it doesn't occur in all cases.  It is probably caused by the fact
that handleResponse is called from timer (pollTimer), to work around
the fact that some browsers call onreadystatechange handler only once
for each state change, and not like required for 'blame_incremental'
as soon as new data is available from server.  It looks like xhr
object is not properly initialized; still it is a bug to throw an
error when accessing xhr.status (and not use 'null' or 'undefined' as
value).

Work around this bug in IE8 by using try-catch block when accessing
xhr.status.

Internet Explorer 8 stops at beginning of blame filling with the
following bug:

It has a firstChild which is a text node containing only whitespace
(single space character) in other web browsers (Firefox 3.5, Opera 10,

particular passing more things as parameters.

While refactoring common code of 'log', 'shortlog' and 'history' view,
we did unify pagination, using always the form used by 'history' view,
namely
  first * prev * next
in place of
  HEAD * prev * next
used by 'log' and 'shortlog' views.

The 'history' view now supports commit limiting via 'hpb' parameter,
similarly to 'shortlog' (and 'log') view.  Performance of 'history'
view got improved a bit, as it doesn't run git_get_hash_by_path for
"current" version in a loop.  Error detection and reporting for
'history' view changed a bit.

Mark Rada b629275fd0 gitweb: Smarter snapshot names
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>

Linkify the avatar icon in log/shortlog view because the icon is directly

Jakub Narebski c4ccf61f4c gitweb: Create links leading to 'blame_incremental' using JavaScript
The new 'blame_incremental' view requires JavaScript to run.  Not all
web browsers implement JavaScript (e.g. text browsers such as Lynx),
and not all users have JavaScript enabled.  Therefore instead of
unconditionally linking to 'blame_incremental' view, we use JavaScript
to convert those links to lead to view utilizing JavaScript, by adding
'js=1' to link.

Currently the only action that takes 'js=1' into account is 'blame',
which then acts as if it was called as 'blame_incremental' action.
Possible enhancement would be to do JavaScript redirect by setting
window.location instead of modifying $format and $action in
git_blame_common() subroutine.

The only JavaScript-aware/using view is currently 'blame_incremental'.
While at it move reading JavaScript to git_footer_html() subroutine.
Note that in this view we do not add 'js=1' currently (even though
perhaps we should; note that for consistency we should also add 'js=1'
in links added by JavaScript part of 'blame_incremental').

This idea was originally implemented by Petr Baudis in
  http://article.gmane.org/gmane.comp.version-control.git/47614
but it added <script> element with fixBlameLinks() function in page
header, to be added as onload event using 'onload' attribute of HTML
'body' element: <body onload="fixBlameLinks();">.  This version adds
script at then end of page (in the page footer), and uses JavaScript
'window.onload=fixLinks();'.  Also in Petr version only links marked
with 'blamelink' class were modified, and they were modified by
replacing "a=blame" by "a=blame_incremental"... which doesn't work for
path_info links, and might replace wrong part if there is "a=blame" in
project name, ref name or file name.

Slightly different solution was implemented by Martin Koegler in
  http://thread.gmane.org/gmane.comp.version-control.git/47902/focus=47905
Here GitAddLinks() function was in gitweb.js file, not as contents of
<script> element.  It was also included in page header (in <head>
element) though, which means waiting for a script to load (and run).
It was smarter in that to "fix" (modify) link, it split URL, modified
value of 'a' parameter, and then recreated modified link.  It avoids
trouble with "a=blame" as substring in project name or file name, but
it doesn't work with path_info URL/link in the way it was written.

Jakub Narebski 4af819d4ca gitweb: Incremental blame (using JavaScript)
Add 'blame_incremental' view, which uses "git blame --incremental"
and JavaScript (Ajax), where 'blame' use "git blame --porcelain".

 * gitweb generates initial info by putting file contents (from
   "git cat-file") together with line numbers in blame table
 * then gitweb makes web browser JavaScript engine call startBlame()
   function from gitweb.js
 * startBlame() opens XMLHttpRequest connection to 'blame_data' view,
   which in turn calls "git blame --incremental" for a file, and
   streams output of git-blame to JavaScript (gitweb.js)
 * XMLHttpRequest event handler updates line info in blame view as soon
   as it gets data from 'blame_data' (from server), and it also updates
   progress info
 * when 'blame_data' ends, and gitweb.js finishes updating line info,
   it fixes colors to match (as far as possible) ordinary 'blame' view,
   and updates information about how long it took to generate page.

Gitweb deals with streamed 'blame_data' server errors by displaying
them in the progress info area (just in case).

The 'blame_incremental' view tries to be equivalent to 'blame' action;
there are however a few differences in output between 'blame' and
'blame_incremental' view:

 * 'blame_incremental' always used query form for this part of link(s)
   which is generated by JavaScript code.  The difference is visible
   if we use path_info link (pass some or all arguments in path_info).
   Changing this would require implementing something akin to href()
   subroutine from gitweb.perl in JavaScript (in gitweb.js).
 * 'blame_incremental' always uses "rowspan" attribute, even if
   rowspan="1".  This simplifies code, and is not visible to user.
 * The progress bar and progress info are still there even after
   JavaScript part of 'blame_incremental' finishes work.

Note that currently no link generated by gitweb leads to this new view.

This code is based on patch by Petr Baudis <pasky@suse.cz> patch, which
in turn was tweaked up version of Fredrik Kuivinen <frekui@gmail.com>'s
proof of concept patch.

This patch adds GITWEB_JS compile configuration option, and modifies
git-instaweb.sh to take gitweb.js into account.  The code for

Giuseppe Bilotta 01b89f0cd5 gitweb: pull ref markes pull out of subject <a> element
Since 4afbaef (gitweb: ref markers link to named shortlogs, 2008-09-02),
ref markers that accompany the subject in views such as shortlog and
history point to something different from the subject itself. Therefore,
they should not be included in the same <a> element.

Benefits of the change are:

 * better compliance to the XHTML standards, that forbid links within
   links even though the restriction cannot be imposed via DTD; this also
   benefits visualization in some older browsers;

 * when hovering the subject, only the subject itself is underlined; when

Mark A Rada cbdefb5ac4 gitweb: add support for XZ compressed snapshots
The XZ compression format uses the LZMA2 compression algorithm, which
often yields higher compression ratios than both GZip and BZip2 at the
cost of using more CPU time and RAM. XZ is the slowest for compression,
but still much faster than BZip2 for decompression, almost comparable
to GZip (see benchmarks below).

Some simple benchmarks show the pros and cons of using XZ compression;
starting with an already tarball'd archive of the repos listed below.
Memory usage seemed to be consistent for any given algorithm at their
respective default compression levels.

From a time and memory perspective, nothing compares to GZip, but if
given an average upload speed of 20KB/s, it would take ~400 seconds
longer to transfer the BZip2'd kernel snapshot than the XZ snapshot;
the transfer time difference is even greater between GZip and XZ. The
real time savings are relatively the same for all test cases, but less
dramatic for smaller repositories.

XZ decompresses ~1.8-2 times slower than GZip, and ~2.7-3.75 times
faster than BZip2; XZ gets relatively faster as snapshots get larger.
However, XZ takes relatively longer to compress as snapshots get larger.

The downside for XZ'd snapshots is the large CPU and memory load put on
the server to generate the compressed snapshot, though XZ will
eventually
have threading support, and the real clock time for making XZ'd
snapshots
would decrease if the server had a beefy multi-core CPU.

XZ compression is disabled by default to allow upgrades to take place
without any surprises, as the CPU and memory requirements will be an
issue for high load or lightweight servers. Also, the XZ format is still
new (format declared stable ~6 months ago), and there have been no
"stable" releases of the utils yet.
