293 | |
294 2006-02-14 Dan Creswell <dan@dancres.org> | |
295 | |
296 * Fix EventGeneratorImpl/VisbilityImpl.ping() to not hold a lock across the | |

305 | |
306 2006-02-02 Dan Creswell <dan@dancres.org> | |
307 | |
308 * Rewrite the contents() core. It was just way too complex, had too much | |
309 retro-fitting and there have been some complaints of duplicates which will | |
310 be down to a hole in the overly complex locking scheme of the old version. | |
311 | |
312 2006-02-01 Dan Creswell <dan@dancres.org> | |
313 | |
314 * Make sure we check for expired transactions in loopback mgr at time of | |

322 | |
323 * Released 1.21-pre4 | |
324 | |
325 2006-01-29 Dan Creswell <dan@dancres.org> | |
326 | |
327 * Fix deadlock which can occur when an operation attempts to add state | |
328 to TxnState whilst it is concurrently being resolved. These operations | |
329 should receive an exception indicating a user-programming error | |
330 but instead cause deadlock. | |
331 | |
332 * Fix bug where we won't kill off associated notify's if we abort a | |
333 non-null transaction. | |
334 | |
335 2006-01-26 Dan Creswell <dan@dancres.org> | |
336 | |
337 * Make sure we close RandomAccessFiles used in logging to prevent some | |
338 OS'en running out of file handles (some seem to cleanup on their own). | |
339 | |
340 * Released 1.21-pre3 (limited circulation) | |
341 | |
342 2006-01-19 Dan Creswell <dan@dancres.org> | |
343 | |
344 * Add support for a loopback transaction manager which can be enabled by | |
345 defining it's Exporter using the configuration variable loopbackTxnExporter. | |
346 Note the manager can only be used to co-ordinate transactions against the | |
347 blitz instance that it shares the JVM with. It cannot co-ordinate multiple | |
348 and/or remote participants such as other Blitz instances | |
349 [EXPERIMENTAL - USE AT YOUR PERIL] | |
350 | |
351 2006-01-12 Dan Creswell <dan@dancres.org> | |
352 | |
353 * Fix bug in BlitzServiceImpl.newView where for JavaSpace05 compatibility | |
354 we should only hold locks if the transaction is non-null. Do the same | |
355 for LocalSpace. Thanks to Simon Vicary for the bug report and unit test | |
356 | |
357 * Released 1.21-pre2 | |
358 | |
359 2006-01-09 Dan Creswell <dan@dancres.org> | |
360 | |
361 * Remove unnecessary BitIndex copy from BitmapIndexer - BitIndex's are | |
362 thread safe so we can iterate without copying. | |
363 | |
364 2006-01-07 Dan Creswell <dan@dancres.org> | |
365 | |
366 * Revise transaction abort to spot situations where we needn't write an | |
367 entry to disk even though we have operations. This optimization is | |
368 triggered when the associated transaction is active and thus no records | |
369 have been written to disk such that undo can be done entirely in memory. | |
370 | |
371 * Fix an unlikely race condition where transaction operations could occur | |
372 after a decision had been taken to optimize and not emit a log record to | |
373 disk. These additional operations would invalidate the decision due to the | |
374 changes in state wrought on a transaction. | |
375 | |
376 2006-01-05 Dan Creswell <dan@dancres.org> | |
377 | |
378 * For write and write(Collection) have proxy populate stub and uuid fields | |
379 to save on network traffic and serialization costs. | |
380 | |
381 2006-01-04 Dan Creswell <dan@dancres.org> | |
382 | |
383 * Remove offset from MangledField and use the loop index server-side | |
384 to derive it. | |
385 | |
386 2006-01-03 Dan Creswell <dan@dancres.org> | |
387 | |
388 * Add support to experimental transport for transaction participant. | |
389 | |
390 * Fixed a socket leak in the experimental transport | |
391 | |
392 2005-12-29 Dan Creswell <dan@dancres.org> | |
393 | |
394 * Fix experimental transport to do readIfExists and takeIfExists correctly | |
395 rather than treat them like their normal brethren. | |
396 | |
397 2005-12-20 Dan Creswell <dan@dancres.org> | |
398 | |
399 * Released 1.20 | |
400 | |
401 2005-12-09 Dan Creswell <dan@dancres.org> | |
402 | |
403 * Make Blitz's internal view generation for contents methods strictly | |
404 apply the entry limit so as to cap memory usage. | |
405 | |
406 2005-12-08 Dan Creswell <dan@dancres.org> | |
407 | |
408 * Fix up nio experimental transport to allow clients to exit (convert | |
409 Txer to use of Daemon threads). | |
410 | |
411 2005-12-07 Dan Creswell <dan@dancres.org> | |
412 | |
413 * Add updateContents configuration variable which can be used to disable | |
414 dynamic updating of contents views - useful for memory consumption control. | |
415 | |
416 2005-12-03 Dan Creswell <dan@dancres.org> | |
417 | |
418 * Fixed deadlock when checkpointing happens concurrently with creation | |
419 of a store by EntryReposFactory | |
420 | |
421 * Released 1.19 | |
422 | |
423 2005-11-26 Dan Creswell <dan@dancres.org> | |
424 | |
425 * Make LocalSpace support JavaSpace05 and leases and proper RemoteEvent | |
426 setup | |
427 | |
428 * Updated documentation to make memory configuration information | |
429 more obvious. | |
430 | |
431 * Released 1.18 | |
432 | |

448 | |
449 * Optimize contents matching to stop doing hierarchy matching once one | |
450 of the template set has hit. | |
451 | |
452 2005-11-20 Dan Creswell <dan@dancres.org> | |
453 | |

460 * Fix a problem where duplicate Entry's could be returned from an | |
461 EntryView in presence of concurrent writes (affects contents()) | |
462 | |
463 * Released 1.16 | |
464 | |
465 2005-11-01 Dan Creswell <dan@dancres.org> | |

480 wasn't on disk | |
481 | |
482 * Fix a recovery issue where the pristine state of a write was inserted | |

484 | |
485 * Released 1.14 | |
486 | |
487 2005-10-20 Dan Creswell <dan@dancres.org> | |
488 | |

519 | |
520 2005-09-16 Dan Creswell <dan@dancres.org> | |

526 | |
527 * Implemented nio-based test transport | |
528 | |
529 * Fixed LeaseImpl to be public for nio test transport | |
530 | |
531 2005-09-11 Dan Creswell <dan@dancres.org> | |
532 | |
533 * Fixed installer to work with JINI 2.1 | |
534 | |

540 locking | |
541 | |
542 * Revised EntryViewAdmin to support leasing and optional transaction | |
543 locking | |
544 | |
545 * Merged tests for bulk ops, contents and visibility | |
546 | |
547 * Created configs for JINI 2.1 and 2.0 | |
548 | |
549 * Add preferred-list to dljar target in build.xml | |
550 | |
551 * Released 1.13-pre7 | |
552 | |
553 2005-09-09 Dan Creswell <dan@dancres.org> | |
554 | |
555 * Added bulk take and write to SpaceImpl | |
556 | |
557 * Added visibility/availability to SpaceImpl | |
558 | |
559 * Added remote interfaces for JavaSpace05 support | |
560 | |
561 2005-09-06 Dan Creswell <dan@dancres.org> | |
562 | |
563 * Fix race condition which could cause TxnPinger to abort a transaction | |
564 that was just committed. | |
565 | |
566 * Internally Released 1.13-pre6 | |
567 | |
568 2005-09-02 Dan Creswell <dan@dancres.org> | |
569 | |
570 * Make FindEntryOpInfo aggressively sync Entry deletion in cases where | |
571 the EntrySleeveImpl is on disk. This ensures better performance in | |
572 cases where we have to hit disk often such as swapping, cold-start | |
573 or FIFO. | |
574 | |
575 * Released 1.13-pre5 | |
576 | |
577 * Fix bug where transaction pinger might encounter | |
578 UnknownTransactionException for a transaction just committed and | |
579 then succeed with an abort thus erroneously undoing the transaction. | |
580 | |
581 2005-08-30 Dan Creswell <dan@dancres.org> | |
582 | |
583 * Refactor oid package to remove external dependency on UIDImpl. | |
584 Masking this makes it easier to introduce a new oid type as required for | |
585 fault tolerance. | |
586 | |
587 * Internally Released 1.13-pre4 | |
588 | |
589 2005-08-24 Dan Creswell <dan@dancres.org> | |
590 | |
591 * Added optional txn status checker which will detect transaction | |
592 manager death and abort associated transactions. Configured with | |
593 variable txnPingInterval as an interval in ms. | |
594 | |
595 * Display the codebase URL for a written Entry when dumping persistent | |
596 logs | |
597 | |
598 2005-08-10 Dan Creswell <dan@dancres.org> | |
599 | |
600 * Clean up some documentation re: JINI 2.1 | |
601 | |
602 * Update activation configuration | |
603 | |
604 * Released 1.13-pre3 | |
605 | |
606 2005-08-05 Dan Creswell <dan@dancres.org> | |
607 | |
608 * Revise persistent logger to use RandomAccessFile in sync mode which | |
609 is slightly faster than forced sync's via Channel. Note that buffer | |
610 size for the logger becomes a significant tuning factor and should be | |
611 sized to hold all concurrent transaction state at each log write. | |
612 | |
613 2005-07-22 Dan Creswell <dan@dancres.org> | |
614 | |
615 * Added support for logging failed takes and reads for use with | |
616 log dump tool. | |
617 | |
618 * Added versioning to Blitz log files | |
619 | |
620 * Added support for upgrade from 1.12 or less | |
621 | |
622 * Removed LoggableAction interface and support. Converted all code to | |
623 use of TxnOp which reduces duplication, increases generic code and | |
624 prepares the way for fault tolerance (fault tolerance preparation). | |
625 | |
626 * Associate lease renewals against Entry's under a write lock with | |
627 the transaction holding the lock rather than emitting them as | |
628 independent records (fault tolerance preparation). | |
629 | |
630 2005-07-21 Dan Creswell <dan@dancres.org> | |
631 | |
632 * Add support for emitting user data as part of a checkpoint snapshot | |
633 | |
634 * Add support for logging instance count summaries to checkpoint | |
635 snapshots and into the log files for use by log dumping tool and | |
636 associated analyzers. | |
637 | |
638 * Added a rudimentary command-line based monitoring tool which some | |
639 may prefer to dashboard | |
640 | |
641 2005-07-19 Dan Creswell <dan@dancres.org> | |
642 | |
643 * Added IOStat to provide statistics from the WriteDaemon. | |
644 | |
645 * Fix bug where FIFOAllocator might not correctly initialize. | |
646 | |
647 * Default write throttle to off. | |
648 | |
649 * Added documentation for log dumping tool | |
650 | |
651 * Released 1.12 | |
652 | |
653 2005-07-18 Dan Creswell <dan@dancres.org> | |
654 | |
655 * Reduce span of Db Txns in SpaceImpl | |
656 | |
657 * Released 1.11 | |
658 | |
659 2005-07-17 Dan Creswell <dan@dancres.org> | |
660 | |
661 * Make DumpEntries correctly initialize Disk before attempting to | |
662 scan. | |
663 | |
664 * Fix a problem where CacheIndexers weren't always notified of Entry | |
665 deletions leading to poor in-cache performance. | |
666 | |
667 2005-07-15 Dan Creswell <dan@dancres.org> | |
668 | |
669 * Fix a deadlock around TxnLocks which occurs under high load when | |
670 task bounds have been hit | |
671 | |
672 2005-07-14 Dan Creswell <dan@dancres.org> | |
673 | |
674 * Revise documentation to include new tools. Split out configuration | |
675 variables into sections and improved layout. | |
676 | |
677 * Revised output format of log dumping tool to be more parser friendly. | |
678 | |
679 2005-07-13 Dan Creswell <dan@dancres.org> | |
680 | |
681 * Convert an errant System.out to a Logger.log | |
682 | |
683 * Add support for manual triggering of lease reaping to complement | |
684 passive and automatic modes. Enabled by setting the relevant reap | |
685 time to LeaseReaper.MANUAL_REAP | |
686 | |
687 * Add a new tool, RequestReap to remotely trigger a manual lease reap. | |
688 | |
689 2005-06-30 Dan Creswell <dan@dancres.org> | |
690 | |
691 * Add more support for log dumping tool. In particular support more | |
692 of the possible records types. | |
693 | |
694 * Add a write queue throttle to prevent memory exhaustion and/or | |
695 overload. | |
696 | |
697 * Add more configuration settings for managing Db. | |
698 | |
699 * Improve recovery progress feedback. | |
700 | |
701 * Make sure we explicitly buffer logs we read during recovery. | |
702 | |
703 2005-06-27 Dan Creswell <dan@dancres.org> | |
704 | |
705 * Released 1.10 | |
706 | |
707 2005-06-26 Dan Creswell <dan@dancres.org> | |
708 | |
709 * Fix bug where transactions finalized in the commiting/aborting thread | |
710 caused deadlock owing to attempts to re-acquire mutex. | |
711 | |
712 2005-06-23 Dan Creswell <dan@dancres.org> | |
713 | |
714 * Fix lock conflict caused by parallel database existence tests and | |
715 database creation (workaround for a Db issue). | |
716 | |
717 2005-06-20 Dan Creswell <dan@dancres.org> | |
718 | |
719 * Make non-wildcard searches terminate immediately we determine there | |
720 cannot be a match. | |
721 | |
722 * Reduce de-serialization in searches | |
723 | |
724 * Reduce de-serialization in handling of recent writes | |
725 | |
726 2005-06-15 Dan Creswell <dan@dancres.org> | |
727 | |
728 * Add initial support for log dumping tool - good for debugging | |
729 both blitz and applications - see exactly what happened during a | |
730 run. | |
731 | |
732 2005-06-03 Dan Creswell <dan@dancres.org> | |
733 | |
734 * Fix database naming conflict caused by naming an Entry field meta | |
735 | |
736 * Released 1.09 | |
737 | |
738 2005-05-30 Dan Creswell <dan@dancres.org> | |
739 | |
740 * Change CacheIndexer default log level | |
741 | |
742 * Added ignoreLogConfig configuration variable to cause Blitz to ignore | |
743 logger Level configuration entry's in it's configuration file. This | |
744 allows a developer to use the standard logger configuration approach | |
745 when appropriate. | |
746 | |
747 2005-04-04 Dan Creswell <dan@dancres.org> | |
748 | |
749 * Fix WriteEntryOpInfo to markDirty committed entries if they are | |
750 not marked dirty when unpinned. If they are pinned they can't have | |
751 been written to disk yet and thus they should still be dirty but | |
752 mightn't be if they got temporarily dropped into WriteScheduler due | |
753 to cache pressure | |
754 | |
755 * Do a pre-check before executing some more costly logging statements | |
756 | |
757 * Don't bother asking for an Entry unless we're going to be able to | |
758 actually initialize an indexer with it | |
759 | |
760 * Tune Db/Java to handle swapping better | |
761 | |
762 * Add a static serialVersionUID to DashboardUI::Factory to avoid | |
763 problems with differences in Inca X releases | |
764 | |
765 * Optimize swapping in transient mode | |
766 | |
767 * Released 1.08 | |
768 | |
769 2005-03-31 Dan Creswell <dan@dancres.org> | |
770 | |
771 * Fix a bug where transaction locks might be released prematurely | |
772 at commit/abort | |
773 | |
774 2005-03-21 Dan Creswell <dan@dancres.org> | |
775 | |
776 * Lower layers of blitz.entry can end up with CacheIndexer's full of | |
777 DELETED Entry's which are wasted matches. Fix CacheIndexers to ignore | |
778 such Entry's | |
779 | |
780 2005-03-15 Dan Creswell <dan@dancres.org> | |
781 | |
782 * Added support for per-Entry type constraints. See | |
783 org.dancres.blitz.config.EntryConstraint | |
784 | |
785 * Added CacheSize constraint to override the global cache setting | |
786 and set a cache size for a specific Entry type. This replaces the | |
787 old mechanism for setting Entry specific cache size - update your | |
788 .config's accordingly | |
789 | |
790 * Added Fifo constraint to enforce FIFO ordering in searches and | |
791 writes for a specific Entry type. | |
792 | |
793 * Added support for Entry browsing to Dashboard - contributed | |
794 by Phil Bishop at Inca X | |
795 | |
796 * Released 1.07 | |
797 | |
798 2005-03-08 Dan Creswell <dan@dancres.org> | |
799 | |
800 * Make StartDashboard's timeout configurable via system property. | |
801 To override the default timeout, specify -DmaxDiscover=<ms> | |
802 | |
803 * Released 1.06 | |
804 | |
805 2005-03-04 Dan Creswell <dan@dancres.org> | |
806 | |
807 * Added disableBitmaps boolean config variable to disable bitmap | |
808 indexing if it proves un-performant or broken. | |
809 | |
810 2005-03-03 Dan Creswell <dan@dancres.org> | |
811 | |
812 * Added support for JavaSpaceAdmin interface as implemented by | |
813 Outrigger. This will allow appropriate space browsers to interrogate | |
814 and modify the contents of a Blitz instance. | |
815 | |
816 * Fix a bug where renew/cancel didn't manage stats correctly | |
817 | |
818 2005-03-01 Dan Creswell <dan@dancres.org> | |
819 | |
820 * Moved reset of stats from SleeveCache::close to | |
821 SleeveCache::deleteAll. | |
822 | |
823 * Added support for caching indexing using Bitmaps. Applicable in | |
824 situations where caches are of fixed size they are much quicker | |
825 than the equivalent HashMapIndexer whilst having similar memory | |
826 consumption in most cases. | |
827 | |
828 2005-02-19 Dan Creswell <dan@dancres.org> | |
829 | |
830 * Added support for remote triggering of Entry cleanup. | |
831 | |
832 * SpaceImpl::find should abort a null transaction in face of exceptions | |
833 not prepAndCommit | |
834 | |
835 * Upgraded to Db 1.7.1 | |
836 | |
837 2005-02-08 Dan Creswell <dan@dancres.org> | |
838 | |
839 * Fixed a nasty race condition in LockCache where an old reference | |
840 can cause invalidation of a current lock. | |
841 | |
842 * Merge support from FT for individual Entry cache sizes. | |
843 | |
844 * Released 1.05 | |
845 | |
846 2005-01-13 Dan Creswell <dan@dancres.org> | |
847 | |
848 * Fix a deadlock which can occur in writing Entry's with small cachesize | |
849 | |
850 * Speculative deadlock fix which might occur in updating Entry's with | |
851 small cachesize | |
852 | |
853 * Split retry/deadlock avoidance code into a framework (RetryingUpdate | |
854 and RetryableOperation) | |
855 | |
856 * Use deadlock avoidance framework in various parts of EntryStorage | |
857 | |
858 * Relax isolation levels on disk-based tuple scans. Reduces lock | |
859 conflicts, lock demands and increases concurrency. Also yields a | |
860 performance improvement even in cache-restricted cases. | |
861 | |
862 * Big thanks to Dylan Wilson for all his testing and reporting effort | |
863 that fuelled the above changes and has resulted in a better product. | |
864 | |
865 * Fixed the release scripts to uniquely name the installer to | |
866 fix SourceForge name conflicts. | |
867 | |
868 * Released 1.04 | |
869 | |
870 2005-01-10 Dan Creswell <dan@dancres.org> | |
871 | |
872 * Fix a deadlock which can occur during deletion of large Entry's. | |
873 (Thanks to Dylan Wilson for a great bug report). | |
874 | |
875 2004-12-31 Dan Creswell <dan@dancres.org> | |
876 | |
877 * Fix a minor problem where an abort can dump a non-fatal | |
878 UnknownTransactionException during recovery. Recovery will still | |
879 complete and no damage has been done. | |
880 | |
881 2004-12-29 Dan Creswell <dan@dancres.org> | |
882 | |
883 * Fixed a bug in meta.Registry where initializer results were not | |
884 forcible commited to disk. | |
885 | |
886 * Released 1.03 | |
887 | |
888 2004-12-20 Dan Creswell <dan@dancres.org> | |
889 | |
890 * Make Blitz obey the contents of initialGroups | |
891 | |
892 * Released 1.02 | |
893 | |
894 2004-12-14 Dan Creswell <dan@dancres.org> | |
895 | |
896 * Make new version attributes override those in LookupStorage | |
897 | |
898 * Released 1.00 | |
899 | |
900 * Fix a deadlock between checkpointer and processing of newly | |
901 arrived Entry's being passed to blocked search tasks | |
902 (thanks to Joseph Wang for another quality bug report) | |
903 | |
904 * Released 1.01 | |
905 | |
906 2004-12-01 Dan Creswell <dan@dancres.org> | |
907 | |
908 * Upgraded to Db/Java 1.7.0 | |
909 | |
910 * Released 0.99 | |
911 | |
912 * Merged FieldsStat from -idev | |
913 | |
914 * Merged Entry structure stuff from -idev dashboard | |
915 | |
916 2004-11-15 Dan Creswell <dan@dancres.org> | |
917 | |
918 * Released 0.98 | |
919 | |
920 2004-11-14 Dan Creswell <dan@dancres.org> | |
921 | |
922 * Reduced -dl.jar footprint | |
923 | |
924 * Merged new rio config containing serviceui support (contributed by | |
925 Jerome Bernard) | |
926 | |
927 2004-11-05 Dan Creswell <dan@dancres.org> | |
928 | |
929 * Fixed dashboard to not tweak the look and feel when run as ServiceUI | |
930 | |
931 2004-11-04 Dan Creswell <dan@dancres.org> | |
932 | |
933 * Added a setContent(null) into ArcCache when swapping a CBD to | |
934 b1 or b2 - reduces memory footprint | |
935 | |
936 2004-10-26 Dan Creswell <dan@dancres.org> | |
937 | |
938 * FindEntryOpInfo should not unpin an Entry - that should only be done | |
939 by WriteEntryOpInfo. This could lead to inaccurate notify behaviour | |
940 under very rare circumstances | |
941 | |
942 2004-09-30 Dan Creswell <dan@dancres.org> | |
943 | |
944 * Fix bug where prepared state may not be restored correctly | |
945 during recovery | |
946 | |
947 * Release 0.97 | |
948 | |
949 2004-09-23 Dan Creswell <dan@dancres.org> | |
950 | |
951 * Fix a deadlock induced by checkpointing whilst an EntryRepository | |
952 is being demand loaded (thanks to Joseph Wang for a great bug report) | |
953 | |
954 * Released 0.96 | |
955 | |
956 2004-09-21 Dan Creswell <dan@dancres.org> | |
957 | |
958 * Fix a potential lock conflict when searches are happening whilst | |
959 WriteDaemon performs a delete | |
960 | |
961 2004-09-16 Dan Creswell <dan@dancres.org> | |
962 | |
963 * Fix a CacheIndexer initialization bug which can break all cache | |
964 matching and associated reads/takes. Typical symptom was an | |
965 ArrayIndexOutOfBoundsException which could be easily confused with | |
966 a false positive caused by Entry schema changes. | |
967 | |
968 2004-09-09 Dan Creswell <dan@dancres.org> | |
969 | |
970 * Fix silly incorrect optimization that breaks matching. | |
971 | |
972 * Released 0.94 | |
973 | |
974 2004-08-22 Dan Creswell <dan@dancres.org> | |
975 | |
976 * Added HostStat | |
977 | |
978 * Added new examples for EntrySizer and a simple HelloWorld | |
979 | |
980 * Added template configurations for handling large objects | |
981 | |
982 * Released 0.93 | |
983 | |
984 2004-08-21 Dan Creswell <dan@dancres.org> | |
985 | |
986 * Tweaked SleeveCache to not bother searching if no entry's are | |
987 present rather than hit cache and then EntryStorage | |
988 | |
989 * Added diagnostic output to CacheIndexer | |
990 | |
991 * Added ServiceUI to the list of required packages for compilation | |
992 | |
993 * Added a snapshot test (from the JSIP package - thanks to Phil and | |
994 Nige) | |
995 | |
996 2004-08-06 Dan Creswell <dan@dancres.org> | |
997 | |
998 * SpaceImpl::write was holding txn open way longer than it needs to. | |
999 | |
1000 2004-08-05 Dan Creswell <dan@dancres.org> | |
1001 | |
1002 * Added throttling support on event and task queues to prevent | |
1003 high-load from causing runaway heap consumption problems. Configured | |
1004 via eventQueueBound and taskQueueBound respectively | |
1005 | |
1006 * Added support for multiple event processor threads in EventQueue | |
1007 to allow for balancing between event generation (typically from writes) | |
1008 and matching/dispatching as remote events. Configured via | |
1009 maxEventProcessors | |
1010 | |
1011 2004-08-03 Dan Creswell <dan@dancres.org> | |
1012 | |
1013 * Make sure we close ObjectStreams used during (un)mangling. | |
1014 This is for tidyness/robustness - doesn't seem to cause a memory leak. | |
1015 | |
1016 2004-08-02 Dan Creswell <dan@dancres.org> | |
1017 | |
1018 * Remove need for initialAttrs to be specified. | |
1019 | |
1020 * Released 0.92 | |
1021 | |
1022 2004-07-31 Dan Creswell <dan@dancres.org> | |
1023 | |
1024 * Added EntrySizer utility to class to assist in storage/memory | |
1025 usage estimation. | |
1026 | |
1027 2004-07-29 Dan Creswell <dan@dancres.org> | |
1028 | |
1029 * Fix build/release to include currently linked je.jar | |
1030 | |
1031 * Released 0.91 | |
1032 | |
1033 2004-07-26 Dan Creswell <dan@dancres.org> | |
1034 | |
1035 * Merged ServiceUI support for dashboard | |
1036 | |
1037 * Released 0.90 | |
1038 | |
1039 2004-07-16 Dan Creswell <dan@dancres.org> | |
1040 | |
1041 * Revised LockMgr to use a reference queue against a standard | |
1042 HashMap rather than SoftHashMap which is less efficient. | |
1043 | |
1044 * Merged a patch from Sleepycat to fix an errant | |
1045 LogFileNotFoundException | |
1046 | |
1047 2004-07-15 Dan Creswell <dan@dancres.org> | |
1048 | |
1049 * Turn off lock timeouts which seem to be breaking things | |
1050 under load | |

1554 * Released V1.1.2 | |
1555 | |
1556 * Fixed a deadlock. Rarely happens as it requires a particular step | |
1557 in checkpoint to happen at exactly the same time as a del of an | |
1558 EntrySleeve from an index. Both the checkpoint and the del must | |
1559 hit the same page at pretty much the same time and in one particular | |
1560 order | |
