2012-03-30gitweb: refactor If-Modified-Since handlingLibravatar W. Trevor King1-28/+29
The current gitweb only generates Last-Modified and handles If-Modified-Since headers for the git_feed action. This patch breaks the Last-Modified and If-Modified-Since handling code out from git_feed into a new function exit_if_unmodified_since. This makes the code easy to reuse for other actions. Only gitweb actions which can easily calculate a modification time should use exit_if_unmodified_since, as the goal is to balance local processing time vs. upload bandwidth.

When using regexp search ('sr' parameter / $search_use_regexp variable is true), check first that regexp is valid. Without this patch we would get an error from Perl during search (if searching is performed by gitweb), or highlighting matches substring (if applicable), if user provided invalid regexp... which means broken HTML, with error page (including HTTP headers) generated after gitweb already produced some output. Add test that illustrates such error: for example for regexp "*\.git" we would get the following error: Quantifier follows nothing in regex; marked by <-- HERE in m/* <-- HERE \.git/ at /var/www/cgi-bin/gitweb.cgi line 3084.

2012-02-26gitweb: Highlight matched part of project description when searching projectsLibravatar Jakub Narebski1-2/+6
Use esc_html_match_hl() from earlier commit to mark match in the _whole_ description when searching projects. Currently, with this commit, when searching projects there is always shown full description of a project, and not a shortened one (like for ordinary projects list view), even if the match is on project name and not project description. Because we always show full description of a project, and not possibly shortened name, there is no need for having full description on mouseover via title attribute. Showing full description when there is match on it is useful to avoid situation where match is in shortened, invisible part. On the other hand that makes project search different than projects list view; also there can be problems with overly-long project descriptions.

2012-02-26gitweb: Introduce esc_html_match_hl and esc_html_hl_regionsLibravatar Jakub Narebski1-0/+41
The esc_html_match_hl() subroutine added in this commit will be used to highlight *all* matches of given regexp, using 'match' class. Ultimately it is to be used in all match highlighting, starting with project search, which does not have it yet. It uses the esc_html_hl_regions() subroutine, which is meant to highlight in a given string a list of regions (given as a list of [ beg, end ] pairs of positions in string), using HTML <span> element with given class. It could probably be used in other places that do highlighting of part of ready line, like highlighting of changes in a diff (diff refinement highlighting). Implementation and enhancement notes: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * Currently esc_html_hl_regions() subroutine doesn't accept any parameters, like esc_html() does. We might want for example to pass nbsp=>1 to it. It can easily be done with the following code: my %opts = grep { ref($_) ne "ARRAY" } @sel; @sel = grep { ref($_) eq "ARRAY" } @sel; This allow adding parameters after or before regions, e.g.: esc_html_hl_regions("foo bar", "mark", [ 0, 3 ], -nbsp => 1); * esc_html_hl_regions() escapes like esc_html(); if we wanted to highlight with esc_path(), we could pass subroutine reference to now named esc_gen_hl_regions(). esc_html_hl_regions("foo bar", "mark", \&esc_path, [ 0, 3 ]); Note that this way we can handle -nbsp=>1 case automatically, e.g. esc_html_hl_regions("foo bar", "mark", sub { esc_html(@_, -nbsp=>1) }, [ 0, 3 ]); * Alternate solution for highlighting region of a string would be to use the idea that strings are to be HTML-escaped, and references to scalars are HTML (like in the idea for generic committags). This would require modifying gitweb code or esc_html to get list of fragments, e.g.: esc_html(\'<span class="mark">', 'foo', \'</span>', ' bar', { -nbsp => 1 }); or esc_html([\'<span class="mark">', 'foo', \'</span>', ' bar'], -nbsp=>1); esc_html_match_hl() could be then simple wrapper around "match formatter", e.g. esc_html([ render_match_hl($str, $regexp) ], -nbsp=>1); Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-02-23gitweb: Faster project searchLibravatar Jakub Narebski1-2/+7
Before searching by some field the information we search for must be filled in, but we do not have to fill other fields that are not involved in the search. To be able to request filling only specified fields, fill_project_list_info() was enhanced in previous commit to take additional parameters which specify part of projects info to fill. This way we can limit doing expensive calculations (like running git-for-each-ref to get 'age' / "Last changed" info) to doing those only for projects which we will show as search results. This commit actually uses this interface, changing gitweb code from the following behavior fill all project info on all projects search projects to behaving like this pseudocode fill search fields on all projects search projects fill all project info on search results With this commit the number of git commands used to generate search results is 2*<matched projects> + 1, and depends on number of matched projects rather than number of all projects (all repositories). Note: this is 'git for-each-ref' to find last activity, and 'git config' for each project, and 'git --version' once. Example performance improvements, for search that selects 2 repositories out of 12 in total: * Before (warm cache): "This page took 0.867151 seconds and 27 git commands to generate." * After (warm cache): "This page took 0.673643 seconds and 5 git commands to generate."

Commit ff7f218 (gitweb: Fix file links in "grep" search, 2012-01-05), added $file_href variable, to reduce duplication and have the fix applied in single place. Unfortunately it made variable defined inside the loop, not taking into account the fact that $file_href was set only if file changed. Therefore for files with multiple matches $file_href was undefined for second and subsequent matches. Fix this bug by moving $file_href declaration outside loop. Adds tests for almost all forms of sarch in gitweb, which were missing from testuite. Note that it only tests if there are no warnings, and it doesn't check that gitweb finds what it should find.

2012-02-17gitweb: Fix "heads" view when there is no current branchLibravatar Jakub Narebski1-2/+2
In a repository whose HEAD points to an unborn branch with no commits, "heads" view and "summary" view (which shows what is shown in "heads" view) compared the object names of commits at the tip of branches with the output from "git rev-parse HEAD", which caused comparison of a string with undef and resulted in a warning in the server log. This can happen if non-bare repository (with default 'master' branch) is updated not via committing but by other means like push to it, or Gerrit. It can happen also just after running "git checkout --orphan <new branch>" but before creating any new commit on this branch. Rewrite the comparison so that it also works when $head points at nothing; in such a case, no branch can be "the current branch", add a test for it. While at it, rename local variable $head to $head_at, as it points to current commit rather than current branch name (HEAD contents). The code still incorrectly shows all branches that point at the same commit as what HEAD points as "the current branch", even when HEAD is detached. Fixing this bug is outside the scope of this patch. Reported-by: Rajesh Boyapati Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-02-03gitweb: Allow UTF-8 encoded CGI query parameters and path_infoLibravatar Jakub Narebski1-8/+8
Gitweb forgot to turn query parameters into UTF-8. This results in a bug that one cannot search for a string with characters outside US-ASCII. For example searching for "Michał Kiedrowicz" (containing letter 'ł' - LATIN SMALL LETTER L WITH STROKE, with Unicode codepoint U+0142, represented with 0xc5 0x82 bytes in UTF-8 and percent-encoded as %C5%82) result in the following incorrect data in search field MichaÅ\202 Kiedrowicz This is caused by CGI by default treating '0xc5 0x82' bytes as two characters in Perl legacy encoding latin-1 (iso-8859-1), because 's' query parameter is not processed explicitly as UTF-8 encoded string. The solution used here follows "Using Unicode in a Perl CGI script" article on http://www.lemoda.net/cgi/perl-unicode/index.html: use CGI; use Encode 'decode_utf8; my $value = params('input'); $value = decode_utf8($value); Decoding UTF-8 is done when filling %input_params hash and $path_info variable; the former requires to move from explicit $cgi->param(<label>) to $input_params{<name>} in a few places, which is a good idea anyway. Also add -override=>1 parameter to $cgi->textfield() invocation in search form. Otherwise CGI would use values from query string if it is present, filling value from $cgi->param... without decode_utf8(). As we are using value of appropriate parameter anyway, -override=>1 doesn't change the situation but makes gitweb fill search field correctly. We could simply use the '-utf8' pragma (via "use CGI '-utf8';") to solve this, but according to CGI.pm documentation, it may cause problems with POST requests containing binary files, and it requires CGI 3.31 (I think), released with perl v5.8.9.

Reusing $project instead of adding a new parameter would have been nicer from a UI point-of-view (including PATH_INFO support) but would complicate the $project validating code that is currently being used to ensure nothing is exported that should not be viewable.

Use of the filter option of git_get_projects_list is currently limited to forks. It currently assumes the project belonging to the filter directory was already validated to be visible in the project list. To make it more generic add an optional argument to denote visibility verification is still needed. If there is a projects list file (GITWEB_LIST) only projects from this list are returned anyway, so no more checks needed. If there is no projects list file and the caller requests strict checking (GITWEB_STRICT_EXPORT), do not jump directly to the given directory but instead do a normal search and filter the results instead. The only effect of GITWEB_STRICT_EXPORT without GITWEB_LIST is to make sure no project can be viewed without also be found starting from project root. git_get_projects_list without this patch does not enforce this but all callers only call it with a filter already checked this way. With this parameter a caller can request this check if the filter cannot be checked this way. Signed-off-by: Bernhard R.

e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding., 2007-12-04) was meant to make gitweb faster by using Perl's internals (see subsection "Messing with Perl's Internals" in Encode(3pm) manpage) Simple benchmark confirms that (old = 00f429a, new = this version): old new old -- -65% new 189% -- Unfortunately it made fallback mode of to_utf8 do not work... except for default value 'latin1' of $fallback_encoding ('latin1' is Perl native encoding), which is why it was not noticed for such long time. utf8::valid(STRING) is an internal function that tests whether STRING is in a _consistent state_ regarding UTF-8. It returns true is well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held as bytes (both these states are 'consistent'). For gitweb the second option was true, as output from git commands is opened without ':utf8' layer. What made it work at all for STRING in 'latin1' encoding is the fact that utf8:decode(STRING) turns on UTF-8 flag only if source string is valid UTF-8 and contains multi-byte UTF-8 characters... and that if string doesn't have UTF-8 flag set it is treated as in native Perl encoding, i.e. 'latin1' / 'iso-8859-1' (unless native encoding it is EBCDIC ;-)). It was ':utf8' layer that actually converted 'latin1' (no UTF-8 flag == native == 'latin1) to 'utf8'. Let's make use of the fact that utf8:decode(STRING) returns false if STRING is invalid as UTF-8 to check whether to enable fallback mode.

2011-12-18gitweb: esc_html() site name for title in OPMLLibravatar Jürgen Kreileder1-1/+2
This escapes the site name in OPML (XML uses the same escaping rules as HTML). Also fixes encoding issues because esc_html() uses to_utf8(). Signed-off-by: Jürgen Kreileder <jk@blackdown.de> Acked-by: Jakub Narębski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-12-18gitweb: Call to_utf8() on input string in chop_and_escape_str()Libravatar Jürgen Kreileder1-0/+1
a) To fix the comparison with the chopped string, otherwise we compare bytes with characters, as chop_str() must run to_utf8() for correct operation b) To give the title attribute correct encoding; we need to mark strings as UTF-8 before outpur Signed-off-by: Jürgen Kreileder <jk@blackdown.de> Acked-by: Jakub Narębski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-10-31gitweb: Add navigation to select side-by-side diffLibravatar Kato Kazuyoshi1-0/+23
Add to the lower part of navigation bar (the action specific part) links allowing to switch between 'inline' (ordinary) diff and 'side by side' style diff. It is not shown for combined / compact combined diff.

2011-10-31gitweb: Use href(-replay=>1,...) for formats links in "commitdiff"Libravatar Jakub Narebski1-8/+8
Use href(-replay->1,...) in (sub)navigation links (like changing style of view, or going to parent commit) so that extra options are preserved. This is needed so clicking on such (sub)navigation link would preserve style of diff; for example when using "side-by-side" diff style then going to parent commit would now also use this style.

2011-10-31gitweb: Give side-by-side diff extra CSS stylingLibravatar Jakub Narebski1-10/+29
Use separate background colors for pure removal, pure addition and change for side-by-side diff. This makes reading such diff easier, allowing to easily distinguish empty lines in diff from vertical whitespace used to align chunk blocks. Note that if lines in diff were numbered, the absence of line numbers [for one side] would help in distinguishing empty lines from vertical align.

2011-10-31gitweb: Add a feature to show side-by-side diffLibravatar Kato Kazuyoshi1-11/+105
This commits adds to support for showing "side-by-side" style diff. Currently you have to hand-craft the URL; navigation for selecting diff style is to be added in the next commit. The diff output in unified format from "git diff-tree" is reorganized to side-by-side style chunk by chunk with format_sidebyside_diff_chunk(). This reorganization requires knowledge about diff line classification, so format_diff_line() was renamed to process_diff_line(), and changed to return tuple (list) consisting of class of diff line and of HTML-formatted (but not wrapped in <div class="diff ...">...</div>) diff line. Wrapping is now done by caller, i.e. git_patchset_body(). Gitweb uses float+margin CSS-based layout for "side by side" diff. You can specify style of diff with "ds" ('diff_style') query parameter. Currently supported values are 'inline' and 'sidebyside'; the default is 'inline'. Another solution would be to use "opt" ('extra_options') for that... though current use of it in gitweb seems to suggest that "opt" is more about passing extra options to underlying git commands, and "git diff" doesn't support '--side-by-side' like GNU diff does, (yet?).

2011-10-31gitweb: Extract formatting of diff chunk headerLibravatar Jakub Narebski1-47/+67
Refactor main parts of HTML-formatting for diff chunk headers (formatting means here adding links and syntax hightlighting) into separate subroutines: * format_unidiff_chunk_header for ordinary diff, * format_cc_diff_chunk_header for combined diff (more than one parent) This makes format_diff_line() subroutine easier to follow.
