git-instaweb: Add support for running gitweb via 'plackup' PSGI is an interface between Perl web applications and web servers, and Plack is a Perl module and toolkit that contains PSGI middleware, helpers and adapters to web servers; see http://plackperl.org PSGI and Plack are inspired by Python's WSGI and Ruby's Rack (and probably JavaScript's Jack/JSGI). Plack core distribution includes HTTP::Server::PSGI, a reference PSGI standalone web server implementation. 'plackup' is a command line launcher to run PSGI applications from command line, connecting web app to a web server via Plack::Runner module. By default it uses HTTP::Server::PSGI as a web server. git-instaweb generates gitweb.psgi wrapper (in $GIT_DIR/gitweb). This wrapper uses Plack::App::WrapCGI to compile gitweb.cgi (which is a CGI script) into a PSGI application using CGI::Compile and CGI::Emulate::PSGI. git-instaweb then runs this wrapper, using by default HTTP::Server::PSGI standalone Perl server, via Plack::Runner. The configuration for 'plackup' is currently embedded in generated gitweb.psgi wrapper, instead of using httpd.conf ($conf). To run git-instaweb with '--httpd=plackup', you need to have instaled Plack core, CGI::Emulate::PSGI, CGI::Compile. Those modules have to be available for Perl scripts (which can be done for example by setting PERL5LIB environment variable). This is currently not documented.

'plackup' is a command line launcher to run PSGI applications from command line, connecting web app to a web server via Plack::Runner module. By default it uses HTTP::Server::PSGI as a web server. git-instaweb generates gitweb.psgi wrapper (in $GIT_DIR/gitweb). This wrapper uses Plack::App::WrapCGI to compile gitweb.cgi (which is a CGI script) into a PSGI application using CGI::Compile and CGI::Emulate::PSGI. git-instaweb then runs this wrapper, using by default HTTP::Server::PSGI standalone Perl server, via Plack::Runner. The configuration for 'plackup' is currently embedded in generated gitweb.psgi wrapper, instead of using httpd.conf ($conf). To run git-instaweb with '--httpd=plackup', you need to have instaled Plack core, CGI::Emulate::PSGI, CGI::Compile. Those modules have to be available for Perl scripts (which can be done for example by setting PERL5LIB environment variable). This is currently not documented.

gitweb: Incremental blame (using JavaScript) 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.
