This avoids taking a performance hit when a huge page +needs to be reconciled. Add a new memory_max_page configuration option. + +[#419] If a page splits, it potentially creates a merge-split internal page +and we potentially walk that page during fast-delete. The WT_REF.addr field +doesn't point to a cell in that case and we'll drop core. + +[#424] Add clarification wording for boolean configuration strings. + +[#425] Perform checkpoints in the calling thread, don't block eviction: when +evicting in a file that is being checkpointed, only evict clean pages. Also +Do compaction in the calling thread instead of interrupting the eviction +thread to do the work. + +[#426] Fixes for automake 1.3.x. Allow examples to run in parallel: give +each a unique home directory. + +Make the tree build without HAVE_VERBOSE. + +Fix some issues with LSM rename and add a Python test. + +Track when cursors refer to memory returned by WiredTiger, copy it if +required before dropping hazard pointers that might be protecting it. + +Verify shouldn't ever modify the file -- don't bother checking for dirty +pages, just discard everything. + +When rolling forward to resolve key prefix compression, don't copy the key, +we only need a reference to it, should speed up tables with lots of key +prefix compression. + +Requested changes for the WT_COMPRESSOR::compress_raw method API: pass in the +configured object's page size as a convenience, and if +WT_COMPRESSOR::pre_size is set, use it to determine the size of the +destination buffer, rather than using the object's page size as the maximum +needed. + + WiredTiger release 1.4.1, 2012-12-12 ------------------------------------ |
