2008-07-03 Version 1.1.0-beta released 2008-06-26 Steve Chu * unix socket connectivity now has be well tested. 2008-06-13 Steve Chu * some code refactoring to improve a bit performance 2008-06-11 Steve Chu * now '-b' option is a tuning way, not a limit. item size that smaller than '-b' value use fast freelist alloc, otherwise, use system 'malloc' instead. Many thanks to Davies Liu for patches and ideas. 2008-06-03 Steve Chu * new support to BerkeleyDB 4.7 - new version is BerkeleyDB 4.7 only, due to the changed bdb api - 'rep_set_request' now use time, not the number of messages * Bugfix: 'pkget' and "multiple get" that return lots of items may cause memory overflow so the daemon crashes. Thanks to Davies Liu * flooded verbose messages of bdb and replication now move to '-vv' option 2008-04-13 Steve Chu * Changes: - allow limitation to 'pkget' and 'pvget' command, use 'pkget/pvget [limit]' to get limited matched items. - 'memcache.py' is also patched for this feature. 2008-04-03 Steve Chu * New features: - add '-T' option to set database type, 'btree' or 'hash' - add '-E' option to enable second database, so we can use 'pvget' - new command 'pkget' that you can get items with a key prefix - new command 'pvget' that you can get items with a value prefix * Changes: - add support to memcache.py for 'pkget' and 'pvget' command, see 'tools/memcache.py' 2008-03-21 Version 1.0.3 released 2008-03-21 Steve Chu * Bugfix: --with-bdb can not find libdb.so and db.h 2008-03-17 Steve Chu * add a '-A' option to set page size, and also can get this value from 'stats bdb' 2008-03-07 Steve Chu * new private command 'rep_set_request' available, to set wehther it allows bulk transfer and also can get this value from 'stats rep'. See 'doc/replication.txt' * mdbtop.py update 2008-03-06 Steve Chu * new private command 'rep_set_bulk' available, to set wehther it allows bulk transfer and also can get this value from 'stats rep'. See 'doc/replication.txt' 2008-03-05 Steve Chu * add 'next_lsn' to 'stats rep' to show master-slave sync status * Make the default ack policy 'DB_REPMGR_ACKS_ONE_PEER' * upgrade 'mdbtop.py' for better rendering 2008-03-04 Version 1.0.2-beta released 2008-03-03 Steve Chu * replication configure changed and improved: - Make the default ack policy 'DB_REPMGR_ACKS_ALL_PEERS' - Make the default ack timeout 20 millisecond - two new private commands 'rep_set_ack_policy' and 'rep_set_ack_timeout' are available to set ack_policy and ack_timeout, and 'stats rep' also includes this two value. See 'docs/replication.txt' 2008-02-29 Steve Chu * give a warning if item buffer size larger than 256KB * memcache.py is patched for private commands. See 'tools/memcache.py' 2008-02-26 Steve Chu * Bugfix: incr/decr is not atomic in multithread, porting mistake from memcached 2008-02-21 Version 1.0.1-beta released 2008-02-21 Steve Chu * Bugfix: some private commands may cause seg fault 2008-02-20 Steve Chu * Bugfix: incr/decr command did not update length string 2008-02-18 Steve Chu * merge all read-only private command of replication into 'stats rep' that memcached client can read it. Original commands are still available. 'stats bdb' is also provided. * 'mdbtop.py', a new monitor tool is added for easy maintaining. See 'tools/mdbtop.py' 2008-02-14 Big Version 1.0.0-beta released 2008-02-01 Steve Chu * Almost entire code is rewritten based on Memcached 1.2.x. * More memcache protocol compatibility, now multiple get and flags are supported, also udp and unix socket is ready(not yet tested). * big performance improved due to memcached 1.2.x code base. Thread is used to resolve the blocked I/O. * use standard build tool, "./configure;make;make install" and done. * two new pravite command for replication to set/get priority. See "doc/replication.txt". 2008-01-21 Version 0.1.1 released 2008-01-21 Steve Chu * Bug fix: out string 'NOT STORED' breaks clients, it should be 'NOT_STORED'! 2007-11-05 Version 0.1.0 released 2007-10-30 Cao Kai , Steve Chu * big replication code merged, let's ship it! using option "-R" to enable replication, two private command is added for replication: db_ismaster, db_whoismaster * code refactor for performance and readability 2007-10-23 Version 0.0.4 released 2007-10-22 Steve Chu * add a new struct db_settings for all db related configures. * big code cleanup for performance. * "-L" option now uses a unit of kbytes. 2007-10-19 Cao Kai * add option "-C" and create a separate thread to do periodic checkpoint * add option "-D" and create a separate thread to do periodic deadlock detecting 2007-10-15 Novey Donar * remove the item key in data.data, about 50% db file size reduced, but not compatible with previous versions, warning to use. 2007-10-08 Steve Chu * add option "-L" to allow to set transaction log buffer * add option "-N" to allow to set DB_TXN_NOSYNC flag, if someone wanted lots of performance improved, but warning to use, because it loses transaction's durability 2007-09-29 Version 0.0.3 released 2007-09-29 Steve Chu * add command "flush_all" that will truncate a database, warning to use. * lots of code formated * Bugfix: Now using "-u" option can get proper db file mode 2007-09-21 Version 0.0.2 released 2007-09-20 Steve Chu * move some macro to memcachedb.h * rename chkpoint to db_checkpoint, for consistency. * add new command "db_archive" to remove log files that are no longer needed * README updated 2007-09-19 Steve Chu * enlarge incr value to unsigned int to conform memcache protocol, now supports max value of 4294967295. 2007-09-18 Version 0.0.1 released
