NAME
ObjStore - Perl Extension For ObjectStore OODBMS
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 (!).
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/ !
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 <when> 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).
