(Fwd) Views on DBI 2.0
- Forwarded message from Marcin Guzowski mar...@guzowski.info - Date: Mon, 29 Dec 2008 05:14:17 -0800 (PST) From: Marcin Guzowski mar...@guzowski.info To: Tim Bunce tim.bu...@pobox.com Subject: Views on DBI 2.0 Hi Tim, We have developed a distributed system written in Perl that needs to maintain multiple db connections across multiple threads (across multiple processes). Unfortunately, we can't use current DBI 1.x module, because it's not threading-safe. AFAIR DBI 2.0 should fix this problem and could be used in multi-threaded apps, is that true? Have you any idea when DBI 2.0 will be out? Cheers, Marcin - End forwarded message -

Have you any idea when DBI 2.0 will be out? I think the plan, to the extent there is a plan, is 'sometime after Perl 6 is available'. It is interesting to speculate 'When will Perl 6 be available'. -- Jonathan Leffler jonathan.leff...@gmail.com #include disclaimer.h Guardian of DBD::Informix - v2008.0513 - http://dbi.perl.org Blessed are we who can laugh at ourselves, for we shall never cease to be amused.

Cheers, Marcin - End forwarded message - Marcin: perhaps if you could elaborate on your architectural needs, it might be possible to discuss threaded options for DBI 1.x with you. FWIW: I've implemented a (heavyweight) Erlang-esque solution in DBIx::Threaded, and had hoped to improve upon it via Thread::Sociable (www.presicient.com/sociable). Alas, other commitments have forced me to suspend development of the latter, but it may possible to resurrect it. Also, recent announcements wrt Perl6's development may disappoint the threads enthusiasts among us. E.g., they've cut STM, and I suspect other threads related features may also be on the chopping block in the interest of delivering a GA language implementation in the next 18 months (Concurrency can be a harsh mistress...)
