2009-11-14gitweb: Make 'history' view (re)use git_log_generic()Libravatar Jakub Narebski1-89/+57
Make git_history use git_log_generic, passing git_history_body as one of its paramaters. This required changes to git_log_generic, in 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.

Put the common parts of git_log and git_shortlog into git_log_generic subroutine: git_log and git_shortlog are now thin wrappers calling git_log_generic with appropriate arguments. The unification of code responsible for 'log' and 'shorlog' actions lead to the following changes in gitweb output * 'tree' link in page_nav now uses $hash parameter, as was the case for 'shortlog' but not for 'log' * 'log' view now respect $hash_parent limiting, like 'shortlog' did * 'log' view doesn't have special case for empty list anymore, and it always uses page_header linking to summary view, like 'shortlog' did.

2009-11-08gitweb: Smarter snapshot namesLibravatar Mark Rada1-16/+60
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> Signed-off-by: Mark Rada <marada@uwaterloo.ca> Signed-off-by: Shawn O.

In pathinfo mode, we use <base href> that refers to the base location of gitweb in order for various external media links to work well. However, this means that for the page to refer to itself, it must regenerate full link, and this is exactly what the blob view page did not do for line numbers.

It's nice to search for an author by merely clicking on their name in gitweb. This is usually faster than selecting the name, copying the selection, pasting it into the search box, selecting between author/committer and then hitting enter. Linkify the avatar icon in log/shortlog view because the icon is directly adjacent to the name and thus more related. The same is not true when in commit/tag view where the icon is farther away.

The custom CGI escaping done in esc_param failed to escape UTF-8 properly. Fix by using CGI::escape on each sequence of matched characters instead of sprintf()ing a custom escaping for each byte.

2009-09-01gitweb: Create links leading to 'blame_incremental' using JavaScriptLibravatar Jakub Narebski1-9/+19
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.

2009-09-01gitweb: Incremental blame (using JavaScript)Libravatar Jakub Narebski1-87/+187
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 git-instaweb.sh was taken from Pasky's patch.

2009-09-01gitweb: Add optional "time to generate page" info in footerLibravatar Jakub Narebski1-0/+29
Add "This page took XXX seconds and Y git commands to generate" to page footer, if global feature 'timed' is enabled (disabled by default). Requires Time::HiRes installed for high precision 'wallclock' time. Note that Time::HiRes is being required unconditionally; this is because setting $t0 variable needs to be done fairly early to have running time of the whole script. If Time::HiRes module were required only if 'timed' feature is enabled, the earliest place where starting time ($t0) could be calculated would be after reading gitweb config, making "time to generate page" info inaccurate.

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 hovering the ref markers, only the text in the hovered ref marker is underlined; previously, hovering any written part of the subject column led to complete underlying of everything at the same time, with unpleasing effects.

2009-08-06gitweb: add support for XZ compressed snapshotsLibravatar Mark A Rada1-0/+9
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.

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.

2009-07-25gitweb: Mark commits with no "previous" in 'blame' viewLibravatar Jakub Narebski1-1/+6
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). Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-07-25gitweb: Use "previous" header of git-blame -p in 'blame' viewLibravatar Jakub Narebski1-14/+15
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.

2009-07-25gitweb: Mark boundary commits in 'blame' viewLibravatar Jakub Narebski1-2/+4
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. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-06-30gitweb: (gr)avatar supportLibravatar Giuseppe Bilotta1-3/+80
Introduce avatar support: the feature adds the appropriate img tag next to author and committer in commit(diff), history, shortlog, log and tag views. Multiple avatar providers are possible, but only gravatar is implemented at the moment. Gravatar support depends on Digest::MD5, which is a core package since Perl 5.8. If gravatars are activated but Digest::MD5 cannot be found, the feature will be automatically disabled. No avatar provider is selected by default, except in the t9500 test.

Collect all author display code in appropriate functions, making it easier to extend these functions on the CGI side. We also move some of the presentation code from hard-coded HTML to CSS, for easier customization. A side effect of the refactoring is that now localtime is always displayed with the 'at night' warning.

2009-05-22gitweb: Sanitize title attribute in format_subject_htmlLibravatar Jakub Narebski1-1/+2
Replace control characters with question mark '?' (like in chop_and_esc_str). 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 (&quot;, &amp;, &lt; and &gt; 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.
