The changes are +as follows: + +[#309] Implement auto-commit of transactions at the API. As well as + ensuring the atomicity of complex operations, this change simplified + code that simulated auto-commit internally and fixed a number of + bugs. + +[#321] Bulk-cursors no longer block checkpoints. We can't write files that + are being bulk-loaded, so change checkpoint to create checkpoints in + the metadata that, if accessed, look like empty files. + + Tighten down the requirements for bulk-load, the only thing that can + be bulk-loaded now is a newly created tree, not any empty file. + +[#329] Add dictionary support to variable-length column store objects. + Support large row-store reconciliation dictionaries: add a skiplist + as the indexing mechanism. + +[#333] Fix a leak of the in-memory transaction log structure and the LSM + data source handle. + +[#334] Fix a memory leak where a page's replacement address wasn't being + freed. + +* Check that LSM trees are not configured as column stores. + +* Fix a race when starting the LSM worker thread. It was possible for the + thread to exit immediately if it started fast enough. + +* Two fixes for LSM, one to ensure that cursors read from a checkpoint if + one is available. The other to reduce the number of empty chunks that can + be created initially. + +* Fix a bug that disabled bloom filters. + +* The configure script checks for Python support in SWIG. + +* If a drop operation fails to acquire all of the handle locks it needs, + make sure it releases the primary handle lock. + +* Fix a number of other minor bugs and memory leaks. + + WiredTiger release 1.3.0, 2012-09-17 ------------------------------------ |
