Dancer and forking
by Andrew Beverley 10 Jul '15

10 Jul '15

Dear all, Is there anything that I should be aware of if using fork() in a dancer application? I have some cache update code which can take a while to run, so I'd rather do it in the background. I've therefore done something like this: post '/data' => sub { my $template = ...; fork and return $template; update_cache; exit; } The actual code is in a module, but you get the idea. Thanks, Andy

Dancer2 v0.161000 on its way to CPAN
by Sawyer X 08 Jul '15

08 Jul '15

Hi everyone, A new version of Dancer2 is on its way to CPAN as we speak. It has a lot of exciting changes that I want to share with you. First of all, it's significantly faster, since the request object is now fully based on Plack::Request. I'm very proud of that. There are still additional spots we want to improve (I'm looking at you, parameters!) and we have room for further optimizations (in fact there's a branch waiting for merging that optimizes it even further), but it's at a much better standing as of this release. Security has improved thanks to work by Andy Beverley (thanks!) and Russell Jenkins (G'day!). Thanks goes to long-time community member, Pedro Melo! The build and install time for Dancer2 has now been substantially improved. We removed unnecessary dependencies (prompted by David Golden!) and no longer require memory cycle tests (unless you have it installed) or Module::Build, since we already support MakeMaker. We now handle a long-standing issue of sending non-hash data. JSON (and other serializers) allow you to serialize arrays or strings but parameters don't work that way. Until now that would crash (and get caught by Dancer, of course, but still annoying), whereas now it silently ignores them for the parameters, but still makes them available via "request->data". An additional "VERSION" method fix, thanks to Miyagawa for reporting! The old dispatcher which goes into effect when you call the "dance" method (although we recommend "to_app" instead) had a small bug fix provided. Changelog with ticket numbers is included below. A big thanks to everyone involved with this release and this lovely community. >From the Dancer core dev team with love, Sawyer. 0.161000 2015-07-08 14:57:16+02:00 Europe/Amsterdam [ BUG FIXES ] * GH #915, #930: Check existence of optional extension headers when behind proxy. (Andy Beverley, Pedro Melo, Russell Jenkins) * GH #926, #940: Set session directory default to $apprdir/session. (Russell Jenkins) * GH #936, #939: Use the error_template configuration on a 404. (Russell Jenkins) * GH #844, #937: Non-hash serialized params do not cause a crash. (Sawyer X) * GH #943: Pass @_ to UNIVERSAL's VERSION so it validates version number. (Sawyer X) * GH #934: Cleanup internals in the old Dispatcher. (Russell Jenkins) [ DOCUMENTATION ] * Sanitize Changes * GH #938: Fix POD link to params keyword. (Ludovic Tolhurst-Cleaver) * GH #935: Provide more details and considerations when using behind_proxy. (Andy Beverley) [ ENHANCEMENT ] * GH #933: use note in tests to produce cleaner non-verbose output (Vernon) * Remove unnecessary dependencies: build chain should be smaller. (Sawyer X) * No need for Module::Build. (Sawyer X) * GH #911: Dancer2 request object is now a subclass of Plack::Request. It's also much faster now. (Sawyer X)
