2016-05-10Merge branch 'sk/gitweb-highlight-encoding'Libravatar Junio C Hamano1-0/+3
Some multi-byte encoding can have a backslash byte as a later part of one letter, which would confuse "highlight" filter used in gitweb. * sk/gitweb-highlight-encoding: gitweb: apply fallback encoding before highlight
2016-05-03gitweb: apply fallback encoding before highlightLibravatar Shin Kojima1-0/+3
Some multi-byte character encodings (such as Shift_JIS and GBK) have characters whose final bytes is an ASCII '\' (0x5c), and they will be displayed as funny-characters even if $fallback_encoding is correct. This is because `highlight` command always expects UTF-8 encoded strings from STDIN. $ echo 'my $v = "申";' | highlight --syntax perl | w3m -T text/html -dump my $v = "申"; $ echo 'my $v = "申";' | iconv -f UTF-8 -t Shift_JIS | highlight \ --syntax perl | iconv -f Shift_JIS -t UTF-8 | w3m -T text/html -dump iconv: (stdin):9:135: cannot convert my $v = " This patch prepare git blob objects to be encoded into UTF-8 before highlighting in the manner of `to_utf8` subroutine.

2016-01-12gitweb: squelch "uninitialized value" warningLibravatar Øyvind A. Holm1-1/+1
git_object() chomps $type that is read from "cat-file -t", but it does so before checking if $type is defined, resulting in a Perl warning in the server error log: gitweb.cgi: Use of uninitialized value $type in scalar chomp at [...]/gitweb.cgi line 7579., referer: [...] when trying to access a non-existing commit, for example: http://HOST/?p=PROJECT.git;a=commit;h=NON_EXISTING_COMMIT Check the value in $type before chomping. This will cause us to call href with its action parameter set to undef when formulating the URL to redirect to, but that is harmless, as the function treats a parameter that set to undef as if it does not exist.

2014-11-18gitweb: hack around CGI's list-context param() handlingLibravatar Jeff King1-1/+5
As of CGI.pm's 4.08 release, the behavior to call CGI::param() in a list context is deprecated (because it can be potentially unsafe if called inside a hash constructor). This causes gitweb to issue a warning for some of our code, which in turn causes the tests to fail. Our use is in fact _not_ one of the dangerous cases, as we are intentionally using a list context. The recommended route by 4.08 is to use the new CGI::multi_param() call to make it explicit that we know what we are doing. However, that function is only available in 4.08, which is about a month old; we cannot rely on having it. One option would be to set $CGI::LIST_CONTEXT_WARN globally, which turns off the warning. However, that would eliminate the protection these newer releases are trying to provide. We want to annotate each site as OK using the new function. So instead, let's check whether CGI provides the multi_param() function, and if not, provide an implementation that just wraps param(). That will work on both old and new versions of CGI. Sadly, we cannot just check defined(\&CGI::multi_param), because CGI uses the autoload feature, which claims that all functions are defined. Instead, we just do a version check.

2013-08-30gitweb: Fix the author initials in blame for non-ASCII namesLibravatar Ævar Arnfjörð Bjarmason1-0/+1
Change the @author_initials feature Jakub added in v1.6.4-rc2-14-ga36817b to match non-ASCII author initials as intended. The regexp Jakub added was intended to match non-ASCII (/\b([[:upper:]])\B/g). But in Perl this doesn't actually match non-ASCII upper-case characters unless the string being matched against has the UTF8 flag. So when we open a pipe to "git blame" we need to mark the file descriptor we're opening as utf8 explicitly. So as a result it abbreviates me to "AB" not "ÆAB", entirely because "Æ" isn't /[[:upper:]]/ unless the string being matched against has the UTF8 flag. Here's something that demonstrates the issue: #!/usr/bin/env perl use strict; use warnings; binmode STDOUT, ':utf8' if $ENV{UTF8}; open my $fd, "-|", "git", "blame", "--incremental", "--", "Makefile" or die "Can't open: $!"; binmode $fd, ":utf8" if $ENV{UTF8}; while (my $line = <$fd>) { next unless my ($author) = $line =~ /^author (.*)/; my @author_initials = ($author =~ /\b([[:upper:]])\B/g); printf "%s (%s)\n", join("", @author_initials), $author; } When that's run with and without UTF8 being true in the environment it gives, on git.git: $ UTF8=0 perl author-initials.pl | sort | uniq -c | sort -nr | head -n 5 99 JH (Junio C Hamano) 35 JN (Jonathan Nieder) 35 JK (Jeff King) 20 JS (Johannes Schindelin) 16 AB (Ævar Arnfjörð Bjarmason) $ UTF8=1 perl author-initials.pl | sort | uniq -c | sort -nr | head -n 5 99 JH (Junio C Hamano) 35 JN (Jonathan Nieder) 35 JK (Jeff King) 20 JS (Johannes Schindelin) 16 ÆAB (Ævar Arnfjörð Bjarmason) Acked-by: Jakub Narębski <jnareb@gmail.com> Tested-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Tested-by: Simon Ruderich <simon@ruderich.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The bug is manifest when running gitweb in a persistent process (e.g. FastCGI, PSGI), and it's easy to reproduce. If a gitweb request includes the searchtext parameter (i.e. s), subsequent requests using the project_list action--which is the default action--and without a searchtext parameter will be filtered by the searchtext value of the first request. This is because the value of the $search_regexp global (the value of which is based on the searchtext parameter) is currently being persisted between requests.

We strip underscores from keys before looking through git-config output for them.

As a result, we end up creating a dictionary of one-to-one elements when the intent was to map mutliple related types to one main type (e.g., bash, ksh, zsh, and sh should all map to sh since they share similar syntax, but we ended up just mapping "bash" to "bash" and so forth).

2012-08-15gitweb: URL-decode $my_url/$my_uri when stripping PATH_INFOLibravatar Jay Soffian1-0/+5
When gitweb is used as a DirectoryIndex, it attempts to strip PATH_INFO on its own, as $cgi->url() fails to do so. However, it fails to account for the fact that PATH_INFO has already been URL-decoded by the web server, but the value returned by $cgi->url() has not been. This causes the stripping to fail whenever the URL contains encoded characters. To see this in action, setup gitweb as a DirectoryIndex and then use it on a repository with a directory containing a space in the name. Navigate to tree view, examine the gitweb generated html and you'll see a link such as: <a href="/test.git/tree/HEAD:/directory with spaces">directory with spaces</a> When clicked on, the browser will URL-encode this link, giving a $cgi->url() of the form: /test.git/tree/HEAD:/directory%20with%20spaces While PATH_INFO is: /test.git/tree/HEAD:/directory with spaces Fix this by calling unescape() on both $my_url and $my_uri before stripping PATH_INFO from them.

And when the line we saw is not a signed-off-by line, we reset $signoff to false before running the remainder of the loop. Hence, the check for $signoff that attempts to remove an extra empty line between two signed-off-by line was not doing anything useful. Rename $empty to a more explicit name $skip_blank_line to tell us to skip a blank line when we see one, set it after we see and emit a blank line (to avoid showing more than one empty lines in a raw) or after we handle a signed-off-by line (to avoid empty lines after such a line), to fix this bug, and get rid of the $signoff variable that is not useful.

2012-04-11gitweb: Refinement highlightning in combined diffsLibravatar Michał Kiedrowicz1-13/+42
The highlightning of combined diffs is currently disabled. This is because output from a combined diff is much harder to highlight because it is not obvious which removed and added lines should be compared. Current code requires that the number of added lines is equal to the number of removed lines and only skips first +/- character, treating second +/- as a line content, Thus, it is not possible to simply use existing algorithm unchanged for combined diffs. Let's start with a simple case: only highlight changes that come from one parent, i.e. when every removed line has a corresponding added line for the same parent. This way the highlightning cannot get wrong. For example, following diffs would be highlighted: - removed line for first parent + added line for first parent context line -removed line for second parent +added line for second parent or - removed line for first parent -removed line for second parent + added line for first parent +added line for second parent but following output will not: - removed line for first parent -removed line for second parent +added line for second parent ++added line for both parents In other words, we require that pattern of '-'-es in pre-image matches pattern of '+'-es in post-image. Further changes may introduce more intelligent approach that better handles combined diffs.

2012-04-11gitweb: Highlight interesting parts of diffLibravatar Michał Kiedrowicz1-12/+95
Reading diff output is sometimes very hard, even if it's colored, especially if lines differ only in few characters. This is often true when a commit fixes a typo or renames some variables or functions. This commit teaches gitweb to highlight characters that are different between old and new line with a light green/red background. This should work in the similar manner as in Trac or GitHub. The algorithm that compares lines is based on contrib/diff-highlight. Basically, it works by determining common prefix/suffix of corresponding lines and highlightning only the middle part of lines. For more information, see contrib/diff-highlight/README. Combined diffs are not supported but a following commit will change it. Since we need to pass esc_html()'ed or esc_html_hl_regions()'ed lines to format_diff_lines(), so it was taught to accept preformatted lines passed as a reference.

2012-04-11gitweb: Push formatting diff lines to print_diff_chunk()Libravatar Michał Kiedrowicz1-19/+18
Now lines are formatted closer to place where we actually use HTML formatted output. This means that we put raw lines in the @chunk accumulator, rather than formatted lines. Because we still need to know class (type) of line when accumulating data to post-process and print, process_diff_line() subroutine was retired and replaced by diff_line_class() used in git_patchset_body() and new restructured format_diff_line() used in print_diff_chunk(). As a side effect, we have to pass \%from and \%to down to callstack. This is a preparation patch for diff refinement highlightning. It's not meant to change gitweb output.

2012-04-11gitweb: Use print_diff_chunk() for both side-by-side and inline diffsLibravatar Michał Kiedrowicz1-16/+39
This renames print_sidebyside_diff_chunk() to print_diff_chunk() and makes use of it for both side-by-side and inline diffs. Now diff lines are always accumulated before they are printed. This opens the possibility to preprocess diff output before it's printed, which is needed for diff refinement highlightning (implemented in incoming patches). If print_diff_chunk() was left as is, the new function print_inline_diff_lines() could reorder diff lines. It first prints all context lines, then all removed lines and finally all added lines. If the diff output consisted of mixed added and removed lines, gitweb would reorder these lines. This is true for combined diff output, for example: - removed line for first parent + added line for first parent -removed line for second parent ++added line for both parents would be rendered as: - removed line for first parent -removed line for second parent + added line for first parent ++added line for both parents To prevent gitweb from reordering lines, print_diff_chunk() calls print_diff_lines() as soon as it detects that both added and removed lines are present and there was a class change, and at the end of chunk.
