Signoff? Compare with my version of this patch: http://repo.or.cz/w/git/jnareb-git.git/commitdiff/0dd15cb3f18e2a26fc834fd3b071e6d3ecc00557 in the gitweb/cache-kernel branch: http://repo.or.cz/w/git/jnareb-git.git/shortlog/refs/heads/gitweb/cache-kernel My commit message looks like the following: .... gitweb: Print to explicit filehandle (preparing for caching) This means replacing print <something>; by print {$out} <something>; and binmode STDOUT, <layer>; by binmode $out, <layer>; where $out is global variable set to \*STDOUT at the beginning of gitweb, but after reading gitweb config. This way it would be simple to e.g. tie output filehandle or use PerlIO layers to simultaneously write to standard output and to some specified file (like "tee" utility does), or redirect output to a scalar, or a file. die_error (re)sets $out to \*STDOUT; we would (probably) want to treat errors in a special way, and do not cache them. The only other differences are reindent of continued lines (if needed), and sometimes word-wrapping lines which this change made too long.

Second, there is no need for separate filehandle for binary files, if you do it correctly (i.e. call binmode on filehandle, and not on STDOUT). When caching is enabled, and 'print {$output_handle} <sth>' prints to in-memory file (or even directly to cache file) it would do conversion, so when reading from cache file we can dump it raw, in binary mode. Third, wouldn't it be better to use shorter variable name, e.g. $out or $oh, instead of $output_handle? We would be able to align print(f) statements without making lines much longer. Fourth, there is slight difference between our $out = *STDOUT; and out $out = \*STDOUT; In the former we have global variable, in latter we have indirect filehandle. CGI::Cache uses the latter form, IIRC. > @@ -3313,7 +3320,7 @@ EOF > if ($use_pathinfo) { > $action .= "/".esc_url($project); > } > - print $cgi->startform(-method => "get", -action => $action) . > + print {$output_handler} $cgi->startform(-method => "get", -action => $action) . > "<div class=\"search\">\n" . > (!$use_pathinfo && > $cgi->input({-name=>"p", -value=>$project, -type=>"hidden"}) . "\n") . Here for example after change gitweb source stops being nicely aligned. OTOH it makes for bigger patch. In my version I did realign.
