+ Revision 580.15 2001/07/29 22:24:04 nbryant
+ - added a new function to the database interface, cdb_close_cursor(). always
+ call this when you're finished with a traversal but didn't bother reading all
+ the way to the end.
+
+ - removed several cdb_begin_transaction()/cdb_end_transaction() calls that are
+ no longer needed because of the read-only cursor support.
+
+ Revision 580.14 2001/07/29 20:56:09 nbryant
+ change ForEachRoom to use read-only cursors by default. it can be overridden to
+ still use read/write cursors by doing:
+
+ cdb_begin_transaction();
+ ForEachRoom(...);
+ cdb_end_transaction();
+
+ the only place I found where it appears necessary to do so is check_ref_counts,
+ so this checkin affects that function too.

+ Revision 580.13 2001/07/29 20:06:33 nbryant
+ generate symlinks to .libs in modules directory
+
+ Revision 580.12 2001/07/28 00:02:50 nbryant
+ implemented read-only cursors. one of the advantages to these is that
+ transactions can be avoided; a cursor operation that occurs within a
+ transaction will often acquire a read lock on every single database page. in
+ general, the Sleepycat documentation recommends avoiding transaction-protected
+ read-only operations where practical. read/modify/write operations can still
+ be transaction protected, of course.
+
+ to use a read-only cursor, call cdb_rewind without a previous call to
+ cdb_begin_transaction. the DB driver will notice this and prevent the current
+ thread from modifying data or starting a transaction until the cursor is
+ closed.
+
+ Revision 580.11 2001/07/27 20:45:44 nbryant
+ libtool has matured a lot since the last time i looked at it (years ago)
+ so we now use it to handle the details of building shared libraries and
+ the linker flags for the main executable.
+
+ in theory this should bring a lot more portability to the dynloader
+ subsystem and enable us to do things like transparently detect GNU vs Sun
+ linkers on solaris, for example
+
+ Revision 580.10 2001/07/27 03:29:04 nbryant
+ missed one thing in the autoconf move
+
+ Revision 580.9 2001/07/27 02:57:43 nbryant
+ support one cursor per database rather than one global cursor
+
+ Revision 580.8 2001/07/27 01:32:07 nbryant
+ remove the automatic transaction demarcation on singleton read operations
+
+ Revision 580.7 2001/07/26 21:43:46 nbryant
+ - move to autoconf 2.52
+ - random warning fix
+ - check for db 3.3
