Ah ok, if it helps in interactive mode, that's fair enough. And I'm happy if the retrieval in the other case is faster :) Cheers, gregor -- .''`.

I've implemented the 2nd part. It does solve (or work-around) the problem with pinto package. I'm still not sure if tearing down the async part is a good idea: it does make the code more complex, but it's helpful in interactive mode. I first need to check whether I can handle the async part with Future (or Promises). Hopefully, using one of these modules will make the async code more readable without removing the benefit of async code.

[ several seconds of dumbfounded silence ] ARRGGGHH I've worked countless hours to shoehorn AnyEvent and async stuff in Config::Model to run parrallel queries to madison. :-( In fact, madison API accepts several packages in a single URL like: http://qa.debian.org/cgi-bin/madison.cgi?package=perl-tk+perl&text=on This will be much faster than running several queries (even parrallel queries). Too bad I did not learn this a few months back. ok. Here's the plan: I'm going to remove all async stuff from Config::Model and Config::Model::Dpkg. This will make the code simpler, well, less complicated. I'll use the URL above to get all required information in blocking mode in C::M::Dpkg::Dependency. If I ever need to run parrallel queries. I'll use Coro or old school fork with IPC. Thoughts ? gregoa, thanks for the wake-up call :-) -- https://github.com/dod38fr/ -o- http://search.cpan.org/~ddumont/ http://ddumont.wordpress.com/ -o- irc: dod at irc.debian.org signature.asc Description: This is a digitally signed message part.

Fixing this properly will require to change all Config::Model code to make it asynchronous. (using Future or Promises). This is a huge work :-( The alternative is to remove the asynchronous stuff and to run the queries to madison in a blocking mode. But running these queries is quite long as soon as you have a lot of dependencies (~ 1s per dependency). The caching mechanism helps a bit but it's not a silver bullet. I'm still stratching my head ... -- https://github.com/dod38fr/ -o- http://search.cpan.org/~ddumont/ http://ddumont.wordpress.com/ -o- irc: dod at irc.debian.org
