Per your request, here's a cc: on the new Ganymede release info. Thanks, Jon ---------------------------------------------------------------------- Ganymede 0.97 is now available for download at ftp://ftp.arlut.utexas.edu/pub/ganymede/ Ganymede is a GPL'ed network directory management system written in Java, providing support for team management of NIS, DNS, etc. -- This release includes a fix to the distribution that caused the schema editor to throw a ClassNotFoundException when examining namespaces. This release includes a number of changes to bring Ganymede closer to being ready for production use. This includes better handling of the journal, database backups, and old versions of emitted build files. The big new feature in this release is that it is now possible to register, unregister, and edit scheduling parameters for all server-side tasks through the Ganymede client, rather than having to edit the server startup java code. Unfortunately, this required an incompatible change in the basic schema definition for the Task object type, so Ganymede 0.97 will not work properly with a ganymede.db file from Ganymede 0.96 or earlier. Ganymede 0.97 comes with new schema files for all of the schema kits, so if you were using one of the included schema files, just re-load your database from the standard input files and you'll be set. -------------------- Changes from 0.96 to 0.97 ------------------- RELEASE DATE: February 10, 1999 1. [DISTRIBUTION] Fixes to the distribution set There was an error in scripts/sync_tree.admin.in.. it didn't include the NameSpaceEditor class required by the admin console's schema editor, so editing namespaces in the schema editor was broken in 0.96. Thanks to frederick.j.dickey@boeing.com for reporting this. 2. [DOCUMENTATION] Fixes to the customization guide The DBEditObject customization guide has lots of references to javadoc pages, but the method links weren't properly constructed for use with the 1.2 javadoc output format. You should now be able to click on method names in the customization guide and be taken directly to the method docs. Brought the guide's content up to date with recent changes to DBEditObject. 3. [SERVER] Amended journal loading code for production mode The journal loading code in the Ganymede server now simply complains politely to stderr if the journal is truncated inappropriately, rather than throwing an IOException. This allows the server to recover gracefully if the server was killed while in the middle of writing a transaction to its journal. The Ganymede server no longer keeps the old journal files around, but rather just keeps a single back-up. While it was entertaining doing a hexdump on old journal files to see what had been done, it cluttered the db directory more than being of any use. 4. [SERVER] Changed how file backups are handled Previously, all of the schema kits' builder tasks copied individual files to file.<date> when the builder task was re-run. Now any time a builder task is executed, the existing output files are zipped into a file named <date>.zip in an 'old' directory in the output directory. Actually, didn't modify all of the kits.. I didn't bother to modify the ganymede.old kit, which is really in need of a major overhaul. The ganymede.db file itself is now archived when the newly created archive task is run (on command by an admin console currently), or when the server starts up with a dirty journal. 5. [SERVER] Enhanced Task Management The server's task scheduling system was basically replaced. The old 'Builder Task' object type is now a generic 'Task' type, with support for editing scheduling parameters directly from the Ganymede client. You can now add, remove, or tweak any task's scheduling parameters from the Ganymede client. Previously, of course, all but the builder tasks were configured by hand in Ganymede.java. Now it will be possible for Ganymede adopters to have total control over task registration and scheduling without having to edit code. The downside to this is that the server will not have the 'standard' tasks scheduled unless the ganymede.db file you are using has the tasks registered. Most importantly, the change from Builder Task to Task object types is an incompatible change from 0.96 and previous releases. You will need to start from scratch with the schema files included in the Ganymede 0.97 release in order to get the new Task object definition that the server now requires. Or, if you are particularly enthusiastic and don't want to lose data already in Ganymede, you could use the schema editor to bring your pre-0.97 datafile into compliance with the 0.97 Task object schema. Generally, I am not committing to a freeze on the basic schema definition until 1.0. I don't expect any more incompatible changes to the basic schema, but no promises until 1.0. See doc/server.html for a guide on the new task scheduling system. 6. [CLIENT] Better taskbar icons Brian reworked the taskbar significantly, with bigger and nicer taskbar icons. The dialogs brought up when the toolbar buttons are clicked have been reworked a bit to be more distinctive. More work coming to the client's GUI in 0.98. 7. [CLIENT] Fixes to date GUI code The date selector dialog now properly shows the time of day set in a date field. You could set the time of day before, but upon reloading, it would not be displayed properly. ------------------------------------------------------------------------------- Jonathan Abbey jonabbey@arlut.utexas.edu Applied Research Laboratories The University of Texas at Austin -------------------------------------------------------------------------------
