Make generated log record and + operation types public. [#1106] + +* Allow eviction worker threads to be started and stopped dynamically. + Applications that use the `eviction_workers` configuration should see the + upgrading documentation on how to use this feature. + [#1116, #1143, #1158] + +Other significant changes: + +* Improve performance and reduce latency during checkpoints and LSM merges. + Remove uses of the checkpoint lock other than serializing checkpoints: + compact holds the schema lock, so it doesn't need to hold the checkpoint + lock, the new WT_BTREE handle close lock prevents checkpoints from colliding + with handle close, so LSM doesn't need the checkpoint lock either. + +* Some minor cleanups, setting the internal session's name in a few places. + [#1073] + +* Grab the live lock when loading a checkpoint in diagnostic mode: that could + race with a read. [#1102] + +* Instead of keeping a list of file URIs for checkpoint to flush, open a handle + and stash it. [#1114] + +* Add a new OS-layer function __wt_fsync_async to flush a file without waiting + for the results, call it from the Btree flush-leaves code so pages start + flushing while we're working the rest of the checkpoint. [#1136, #1152] + +* Wait for the handle flush lock when writing the leaf pages instead of + returning EBUSY. [#1136] + +* Add a wtperf page to the documentation, describe how to simulate workloads + and view statistics. [#1147] + +* Flag new structures not listed in PREDEFINE. [#1148] + +* Return EBUSY if no async handles available and fix ex_async to look for it. + [#1153] + +* Fix some problems with navigation in the reference guide. + +* Bump the number of slots for internal sessions: we have a lot more than 2 + now. Add a test for `session_max` settings, make sure we add enough to + account for at least the default internal sessions. + +* Remove tcbench: we're no longer maintaining it. + + WiredTiger release 2.3.0, 2014-07-29 ------------------------------------ @@ -1,4 +1,4 @@ -WiredTiger 2.3.1: (July 30, 2014) +WiredTiger 2.3.1: (August 14, 2014) This is version 2.3.1 of WiredTiger. diff --git a/build_posix/aclocal/version-set.m4 b/build_posix/aclocal/version-set.m4 index 7da359b97c5..291ae33cccb 100644 --- a/build_posix/aclocal/version-set.m4 +++ b/build_posix/aclocal/version-set.m4 @@ -3,7 +3,7 @@ dnl build by dist/s_version VERSION_MAJOR=2 VERSION_MINOR=3 VERSION_PATCH=1 -VERSION_STRING='"WiredTiger 2.3.1: (July 30, 2014)"' +VERSION_STRING='"WiredTiger 2.3.1: (August 14, 2014)"' AC_SUBST(VERSION_MAJOR) AC_SUBST(VERSION_MINOR) |
