- switched from mmap based writing to simpler stdio based writing. Has a minor impact (0.5 microseconds) on microbenchmarks for asynchronous writes. Synchronous writes speed up from 30ms to 10ms on linux/ext4. Should be much more reliable on diverse platforms. - compaction errors now immediately put the database into a read-only mode (until it is re-opened). As a downside, a disk going out of space and then space being created will require a re-open to recover from, whereas previously that would happen automatically. On the plus side, many corruption possibilities go away. - force the DB to enter an error-state so that all future writes fail when a synchronous log write succeeds but the sync fails. - repair now regenerates sstables that exhibit problems - fix issue 218 - Use native memory barriers on OSX - fix issue 212 - QNX build is broken - fix build on iOS with xcode 5 - make tests compile and pass on windows
