=head1 NAME ObjStore - Perl Extension For C OODBMS =head1 SYNOPSIS Like perl? Sick of SQL? Ready to try something new? This extension implements databases that look exactly like normal perl. The same can also be extended with arbitrary C++ objects (!). =head1 PREREQUISITES You will need: - ObjectStore 5.1 (see http://www.odi.com; evaluations are available!) - Perl 5.005 (perl 5.004_04 might still work) - Tree::Fat perl extension - ExtUtils::ExCxx (only needed on Digital UNIX, HP (5.x), OS/2 (3.x), or MS Windows NT/95; send email) See http://www.perl.com/CPAN/authors/id/JPRIT/ ! =head1 R!CENT CHANGES ** 07-28-98 RELEASE 1.43 - Fixed index bugs. The lexicographical ordering logic was broken. Also there was a potential memory corruption problem. ** 07-27-98 RELEASE 1.42 - ObjectStore 5.1 is required. Static linkage is no longer supported. OTOH, it is now easy to create persistent C++ objects that are seemlessly integrated into perl databases. Raw C++ performance must be sacrificed no longer! As there is no longer any application schema, APIs to configure it have been removed. A new environment variable, OSPERL_SCHEMA_DBDIR, overrides the default schema directory. Indu Strypundit is quoted as calling this release a tour-de-force of technical bravada. "We suspected that the number forty-two in the version might be significant. It was." - Many of the core API classes have been through yet another round of extensive polishing in preparation for a binary API freeze (or at least a chill :-). The pathexam apparatus has been entirely rewritten and is now available at the perl level as ObjStore::PathExam. - Various osperlserver enhancements including: a -shutdown option, an -reload option, and a automatic snapshotting of all VERSIONs on startup (see ObjStore::Serve). - Simplified read-only protocol for indices. Either keys are indexable just once or they must be read-only. - A few more problems with exception handling were fixed. Errors were not being reported properly in rare circumstances. - Use the 'methods' command to enquire about available methods in posh (5.005 only). - Schema support for non-ObjStore::Index cursors and ObjStore::Set have been dropped. sync_INC/get_INC is no longer supported. The readonly method is no longer implemented (but you can still check easily with eval). see ./INSTALL for hints on installation see ./UPGRADE to evolve databases from prior releases see ./TODO for a list of stuff in the queue see ./CHANGES for a visionary perspective Perl-ObjectStore mailing list is waiting for your contribution-- - If you're having trouble or if you've run into a bug. - Any job postings (as long as they relate to this extension.
