The changes are as follows: + +[#370] Document that applications are responsible for figuring out their + upgrade path if they might swap out compression engines. + +[#371] When a single session was used to reconcile multiple btrees, one of + which had dictionaries configured and one of which didn't, we failed to + clear the dictionary when starting page reconciliation. Be consistent, + never use anything other than the btree handle's configuration to decide + if we're using a dictionary in a reconcilation run. + +[#372] Fix several potential integer overflow bugs. + +[#373] Fix a bug where calls that performed an operation on multiple objects + (such as creating a table that implicitly creates a column group) + could leave the metadata incomplete if a process exited without + calling `WT_CONNECTION::close`. + Hold the schema lock while opening tables. Fixes the error "cannot be + opened until all column groups are created" message when create calls + race with open_cursor. + +[#374] Fix a race that caused crashes when using the Python API with + multi-threaded code. + +[#375] Fix a bug in __wt_cond_wait - so that it returns after timeout expires. + +* Protect the list of LSM trees with the schema lock to avoid races during + create. + +* Update ex_test_perf to output statistics during populate and improve timing + accuracy. + +* Skew eviction in favor of leaf pages - which improves read-only performance + for large LSM trees. + +* Hold the LSM tree lock while gathering statistics. + +* Fix a bug in bulk load of bitmap files. + +* Fix a related bug in the bloom code that uses bitmap stores. + +* Don't attempt to drop the first chunk of an LSM tree before creating it. + +* Instead of entering a fake key cell after the last cell on the page just + in case the page ends with a key cell which has no value, use the end of + the page to detect that case. + +* Cache cursor key/value formats in Python, to save a native call from every + get_key/value. + +* Don't sync the directory after open if the global "sync" flag is false. + +* Fix a race for LSM trees that could happen if two threads race to open a + cursor and drop the LSM tree. + WiredTiger release 1.3.4, 2012-10-19 ------------------------------------ |
