Here we go with Ampoule 0.1, the first beta release after 5 alphas. Featuring this release is simply support for a timeout time to avoid having all processes in the pool stuck on some commands. Unfortunately today PyPI is a bit broken and I can't upload the release there yet, however it's available on launchpad: https://launchpad.net/ampoule/ampoule/0.1 Right now my launchpad issue tracker is empty, which means that I've now implemented all the features that I was originally looking for in a process pool. Now the ball is in your hands dear users! :). Give me features to implement and I'll be glad to work on them. For the bunch of you worried about maturity of the project: it's obviously very young but at adroll.com we are using it in production systems, specifically to drive a pool of gtkWebKit processes that take screenshots of web pages. In my view this is one of the worst cases for worker processes because web sites leak like hell, so far it's been working flawlessly for over a week. Maybe soon we'll release also that project as open source. So, have fun using it. Below a more detailed changeset. This release was sponsored by Super Happy Dev House ;P. Ampoule 0.1 (2008-11-15) ========================== Changes -------- - Fixed bug #276841: Add timeout for subprocess calls. The ProcessPool constructor now supports an additional timeout argument that specifies a pool level timeout, in seconds, before which every call ever made should return. Alternatively there is also a per-call mechanism. Currently this second per-call system is not available when using the remote pool service, so be sure to set the timeout command line parameter at an high enough level to satisfy all the possible commands. If a command doesn't require an answer the timeout doesn't apply, of course. The error returned when a call is timedout is 'error.ProcessTerminated'. On *nix systems the process is terminated with signal 9, on windows ampoule uses SIGTERM and returns error code 255. -- Valentino Volonghi aka Dialtone Now running MacOS X 10.5 Home Page: http://www.twisted.it http://www.adroll.com
