497d9c3439 gitweb: clarify search results page when no matching commit found
When searching commits for a string that never occurs, the results
page looks something like this:

	projects / foo.git / search                                 \o/
	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).

7f425db914 gitweb: allow configurations that change with each request
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.

869d58813b gitweb: Move evaluate_gitweb_config out of run_request
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).

Former run() subroutine got renamed to run_request().  The new run()
subroutine can run multiple requests at once if run as FastCGI script.

To run gitweb as FastCGI script you must specify '--fastcgi' / '-f'
command line option to gitweb, otherwise it runs as an ordinary CGI
script.

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.

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
for other syntax highlighing solutions, or make it smarter by not
re-running `git cat-file` second time.

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).

Add some basic test of syntax highlighting (with 'highlight' as
prerequisite) to t/t9500-gitweb-standalone-no-errors.sh test.

While at it make git_blob Perl style prettier.

  Variable "$project_maxdepth" may be unavailable at gitweb.cgi line 2443.
  Variable "$projectroot" may be unavailable at gitweb.cgi line 2451.

Those are false positives; silence those warnings by explicitely

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.

This would make it easier in the future to add support or improve

It would also make it easier to make use of die_error() as an error

Perl 5 allows non-local jumps; the restriction is that you cannot jump

377bee3424 gitweb: href(..., -path_info => 0|1)
If named boolean option -path_info is passed to href() subroutine, it
would use its value to decide whether to generate path_info URL form.
If this option is not passed, href() queries 'pathinfo' feature to
check whether to generate path_info URL (if generating path_info link
is possible at all).

href(-replay=>1, -path_info=>0) is meant to be used to generate a key
for caching gitweb output; alternate solution would be to use freeze()
from Storable (core module) on %input_params hash (or its reference),
e.g.:
  $key = freeze \%input_params;
or other serialization of %input_params.

8de096b671 gitweb: simplify gitweb.min.* generation and clean-up rules
GITWEB_CSS and GITWEB_JS are meant to be "what URI should the installed
cgi script use to refer to the stylesheet and JavaScript", never "this

While we are at it, lose FILES that is used only for "clean" target in a
misguided way.  "make clean" should try to remove all the potential
build artifacts regardless of a minor configuration change. Instead of
trying to remove only the build product "make clean" would have created
if it were run without "clean", explicitly list the three potential build
products for removal.

0e6ce21361 Gitweb: add support for minifying gitweb.css
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.

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.

1df4876613 gitweb: Protect escaping functions against calling on undef
This is a bit of future-proofing esc_html and friends: when called
with undefined value they would now would return undef... which would
probably mean that error would still occur, but closer to the source
of problem.

This means that we can safely use
  esc_html(shift) || "Internal Server Error"
in die_error() instead of
  esc_html(shift || "Internal Server Error")

453541fcfc gitweb: esc_html (short) error message in die_error
The error message (second argument to die_error) is meant to be short,
one-line text description of given error.  A few callers call
die_error with error message containing unescaped user supplied data
($hash, $file_name).  Instead of forcing callers to escape data,
simply call esc_html on the parameter.

Note that optional third parameter, which contains detailed error
description, is meant to be HTML formatted, and therefore should be
not escaped.

While at it update esc_html synopsis/usage, and bring default error
description to read 'Internal Server Error' (titlecased).

e6e592db4c gitweb: Die if there are parsing errors in config file
Otherwise the errors can propagate, and show in damnest places, and
you would spend your time chasing ghosts instead of debugging real
problem (yes, it is from personal experience).

This follows (parts of) advice in `perldoc -f do` documentation.

This required restructoring code a bit, so we die only if we are reading
(executing) config file.  As a side effect $GITWEB_CONFIG_SYSTEM is always
available, even when we use $GITWEB_CONFIG.

57017b3e15 gitweb: Simplify (and fix) chop_str
The chop_str subroutine is meant to be used on strings (such as commit
description / title) *before* HTML escaping, which means before
applying esc_html or equivalent.

Therefore get rid of the failed attempt to always remove full HTML
entities (like e.g. &amp; or &nbsp;).  It is not necessary (HTML
entities gets added later), and it can cause chop_str to chop a string
incorrectly.

Specifically:

     API & protocol: support option to force written data immediately to disk

from http://git.kernel.org/?p=daemon/distsrv/chunkd.git;a=commit;h=3b02f749df2cb1288f345a689d85e7061f507e54

The short version of the title gets chopped to

     API ...

where it should be

     API & protocol: support option to force written data...
