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.

An optional -action_extra parameter is given to git_header_html() to

this can be used to specify that the remotes view is being used for a

Eli Barzilay noticed that

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

Now evaluate_git_version() is inside run_request() to be called for each

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

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

t7105-reset-patch.sh
t7501-commit.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.

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).

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 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

This commit implements both 1.) and 2.), i.e. gitweb_get_feature() doesn't

project), and git_get_project_config() returns early if $git_dir is not

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")

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).

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. & or ). It is not necessary (HTML
entities gets added later), and it can cause chop_str to chop a string
incorrectly.

This changes slightly the behavior of gitweb, so that it verifies
that the box isn't inundated with before attempting to serve gitweb.
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.

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>

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.

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

because setting $t0 variable needs to be done fairly early to have

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.

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.

For example for "Junio C Hamano" initials would be "JH". Of course
initials are added (below shortened SHA-1 of blamed commit) only if
group of lines that blame the same commit has 2 or more lines in it.
Initials are extracted using i18n /\b([[:upper:]])\B/g regexp.
Additionally initials help to distinguish boundary commits, as they
use bold weight font too (in addition to shortened SHA-1 of commit).

Use "no-previous" class to mark blamed commits which do not have
"previous" header. Those are commits in which blamed file was created
(added); this includes boundary commits. This means that 'linenr'
link leads to blamed commit, not (one of) parent of blamed commit.
Therefore currently line number for such commit uses bold weight font
to denote this situation; the effect is subtle.
Use "multiple-previous" class in the opposite situation, where blamed
commit has multiple "previous" headers (is an evil merge). Currently
this class is not used for styling. In this situation 'linenr' link
leads to first of "previous" commits (first parent).

Luben Tuikov changed 'lineno' link (line number link) from pointing to
'blame' view at given line at blamed commit, to the one at parent of
blamed commit in
244a70e (Blame "linenr" link jumps to previous state at
"orig_lineno", 2007-01-04).
This made it possible to do data mining using 'blame' view, by going
through history of a line using mentioned line number link.
Original implementation called "git rev-parse <commit>^" to find SHA-1
of a parent of a given commit once per each blamed line. In
39c19ce (gitweb: cache $parent_commit info in git_blame(),
2008-12-11)
this was improved so rev-parse was called once per each unique commit
in git-blame output. Alternate solution would be to relax validation
for 'hb' parameter by allowing extended SHA-1 syntax of the form
<rev>^ (perhaps redirecting to gitweb URL with <rev>^ resolved, in
practice moving call to rev-parse to 'the other side of link').
This solution had a bug that it didn't work for boundary commits.
Boundary commits don't have parents, so "git rev-parse <commit>^"
returned literal "<commit>^" (which didn't exists). Gitweb didn't
detect this situation and passed this result literally as 'hb'
parameter in 'linenr' link. Following such link currently gives
400 - Invalid hash base parameter
error; 'hb' parameter is restricted via validate_refname to correct
refnames and doesn't allow for extended SHA-1 syntax. This bug could
have been fixed alternatively by checking if commit is boundary commit,
or check if rev-parse result is unchanged (still ends in '^' prefix).
The solution employing rev-parse to find parent of commit had inherent
problem if blamed commit renamed file; then name of file would be
different in its parent. Solving this outside git-blame would be
difficult and costly (at least cost of additional fork for extra git
command).
Currently gitweb uses information in "previous" header, which was
introduced by Junio C Hamano in
96e1170 (blame: show "previous" information in
--porcelain/--incremental format, 2008-06-04)
This (currently undocumented) header has the following format:
"previous <sha1 of parent commit> <filename at parent>"
Using "previous" header solves both problem of performance and the
problem that blamed commit could have renaming blamed file.
Because "previous" header can be repeated for the same commit when
blamed commit is merge (has more than one parent), and we are
interested usually in _first_ parent, currently we store only first
value if blame header repeats. Using first parent (first "previous"
line) was what gitweb did before; without this change gitweb would use
last parent instead.
If there is no previous commit 'linenr' link points to blamed commit
and blamed filename, making it work correctly for boundary commits.

Use "boundary" class to mark boundary commits, which currently results
in using bold weight font for SHA-1 of a commit (to be more exact for
all text in the first cell in row, that contains SHA-1 of a commit).
Detecting boundary commits is done by watching for "boundary" header
in "git blame -p" output. Because this header doesn't carry
additional data the regular expression for blame header fields
had to be slightly adjusted.
With current gitweb API only root (parentless) commits can be boundary
commits.

A little background: some web browsers turn on strict (and
unforgiving) XML validating mode for XHTML documents served using
application/xhtml+xml content type. This means among others that
control characters are forbidden to appear in gitweb output.
CGI.pm does by default slight escaping (using simple_escape subroutine
from CGI::Util) of all _attribute_ values (depending on the value of
autoEscape, by default on). This escaping, at least in CGI.pm version
3.10 (most current version at CPAN is 3.43), is minimal: only '"',
'&', '<' and '>' are escaped using named HTML entity references
(", &, < and > respectively). But simple_escape does
not do escaping of control characters such as ^X which are invalid in
XHTML (in strict mode).
If by some accident commit message do contain some control character
in first 50 characters (more or less) of first line of commit message,
and this line is longer than 50 characters (so gitweb shortens it for
display), then gitweb would put this control character in title
attribute (and CGI.pm would not remove them). The tag _contents_ is
safe because it is escaped using esc_html() explicitly, and it
replaces control characters by their printable representation.
While at it: chop_and_escape_str doesn't need capturing group.

The current implementation only hyperlinks the first hash on
a given line of the commit message. It seems sensible to
highlight all of them if there are multiple, and it seems
plausible that there would be multiple even with a tidy line
length limit, because they can be abbreviated as short as 8
characters.
Benchmark:
I wanted to make sure that using the 'e' switch to the Perl regex
wasn't going to kill performance, since this is called once per commit
message line displayed.
In all three A/B scenarios I tried, the A and B yielded the same
results within 2%, where A is the version of code before this patch
and B is the version after.
1: View a commit message containing the last 1000 commit hashes
2: View a commit message containing 1000 lines of 40 dots to avoid
hyperlinking at the same message length
3: View a short merge commit message with a few lines of text and
no hashes
All were run in CGI mode on my sub-production hardware on a recent
clone of git.git. Numbers are the average of 10 reqests per second
with the first request discarded, since I expect this change to affect
primarily CPU usage. Measured with ApacheBench.
Note that the web page rendered was the same; while the new code
supports multiple hashes per line, there was at most one per line.
The primary purpose of scenarios 2 and 3 were to verify that the
addition of 1000 commit messages had an impact on how much of the time
was spent rendering commit messages. They were all within 2% of 0.80
requests per second (much faster).
So I think the patch has no noticeable effect on performance.

When a feature like "blame" is permitted to be overridden in the
repository configuration but it is not actually set in the repository,
a warning is emitted due to the undefined value of the repository
configuration, even though it's a perfectly normal condition.
Emitting warning is grounds for test failure in the gitweb test
script.
This error was caused by rewrite of git_get_project_config from using
"git config [<type>] <name>" for each individual configuration
variable checked to parsing "git config --list --null" output in
commit b201927 (gitweb: Read repo config using 'git config -z -l').
Earlier version of git_get_project_config was returning empty string
if variable do not exist in config; newer version is meant to return
undef in this case, therefore change in feature_bool was needed.
Additionally config_to_* subroutines were meant to be invoked only if
configuration variable exists; therefore we added early return to
git_get_project_config: it now returns no value if variable does not
exists in config. Otherwise config_to_* subroutines (config_to_bool
in paryicular) wouldn't be able to distinguish between the case where
variable does not exist and the case where variable doesn't have value
(the "[section] noval" case, which evaluates to true for boolean).
While at it fix bug in config_to_bool, where checking if $val is
defined (if config variable has value) was done _after_ stripping
leading and trailing whitespace, which lead to 'Use of uninitialized
value' warning.
Add test case for features overridable but not overriden in repo
config, and case for no value boolean configuration variable.

CGI::url() has some issues when rebuilding the script URL if the script

Another issue is that the resulting URL cannot be used for the <base>

otherwise.
We fix this by building the proper base URL ourselves, and improve the

Additionally t/t9500-gitweb-standalone-no-errors.sh had to be modified

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

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".

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.

Among others, here are the highlights:
* move variable declaration closer to the place it is set and used,
if possible,
* uniquify and simplify coding style a bit, which includes removing
unnecessary '()'.
* check type only if $hash was defined, as otherwise from the way
git_get_hash_by_path() is called (and works), we know that it is
a blob,
* use modern calling convention for git-blame,
* remove unused variable,
* don't use implicit variables ($_),

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.

* gb/gitweb-snapshot-pathinfo:
gitweb: embed snapshot format parameter in PATH_INFO
gitweb: retrieve snapshot format from PATH_INFO
gitweb: make the supported snapshot formats array global
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.

When PATH_INFO is active, get rid of the sf CGI parameter by embedding

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
hand-coded URLs for extremely unusual project.

<$git_dir/ctags/*> does not correctly enumerate the cloud tags files at
all.

immediately yields undef, which in turn gives an undef value warning to

Since input parameters can be obtained both from CGI parameters and
PATH_INFO, we would like most of the code to be agnostic about the way
parameters were retrieved. We thus collect all the parameters into the
new %input_params hash, delaying validation after the collection is
completed.
Although the kludge removal is minimal at the moment, it makes life much
easier for future expansions such as more extensive PATH_INFO use or
other form of input such as command-line support.

The "Content tags" (nothing to do with usual Git tags!) are free-form
strings that are attached to random projects and displayed in the
well-known Web2.0-ish tag cloud above project list.
The feature will make use of HTML::TagCloud if available, but will
still display (less pretty) list of tags in case the module is not
installed.
The tagging itself is not done by gitweb - user-provided external
helper CGI needs to be provided; one example is the tagproj.cgi
of Girocco. This functionality might get integrated to gitweb
in the future.
The tags are stored one-per-file in ctags/ subdirectory. The reason
they are not stored in the project config file is that you usually
want to give anyone (even CGI scripts) permission to create new tags
and they are non-essential information, and thus you would make
the ctags/ subdirectory world-writable.
