By the way, are you doing if-elsif fallback chain, trying different mechanisms (like '/proc/loadavg', BSD::getloadavg, etc.), or did you made get_loadavg() into code reference, i.e. run it with $get_loadavg->(), which has the advantage that the gitweb admin can override it in gitweb config file (including such thing like simply using load average over last 5 minutes, and not over last minute)? > The second changes the error message to use/abuse die_error() > vs. doing it's own thing (though I still think this should be on by > default). True, the error message could use improvement (and not only using its own class instead of abusing 'readme' class, or renaming 'readme' class to something more generic). The problem with error message for this is who is the target of this message: is it gitweb administrator (who can change gitweb configuration), or is it gitweb user (who need to contact web admin). The problem with this patch is that for it to be useful for protecting against silent errors it should be on by default, but OTOH having it on by default is quite inconvenient. Best solution would be to treat core of this issue, namely eliminate silent errors and always provide some message in case of error. > Patch 4 I don't have anything to add or change at this point. > > This patch has me pondering and I'm unsure of what I'd suggest, mainly > because of the addition of the smart http support meaning that git:// > and http:// are legitimate and useful links for supporting full git > transactions. > > I may withdraw the patch entirely since the link on kernel.org has been > around for years, and I'm unsure if anything actually uses it (though I > can see it being useful still).

Also, it has to be _fast_, I think, i.e. no reading cloneurl and repo config (for gitweb.url) for each repository. You can always remove the check for "git://" prefix, and/or take first base in @git_base_url_list. > > I have given some initial thought to converting the $output options I'm > currently using to a print <FH> that Jakub is suggesting & exploring.

Errr... what? Forcing buffering (you need to read whole output into memory, including for snapshots (uncompressed in case of .tar.gz)) is IMVHO orthogonal to the issue of separating data & layout. BTW. Modern web server interfaces like Rack, PSGI/Plack etc. explicitly include streaming support. The advantage of doing 'print {$fh}' is that $fh can be \*STDOUT, can be \$buffer, but can be filehandle to (temporary) file on disk, and you can even "tee" it, i.e. both write to memory/file, and to STDOUT. The number of possible choices / possible improvements is much larger. And what is also important it means that people who do not use caching do not suffer latency penalty and memory pressure from caching infrastructure they do not use. P.S.
