Summary: added a new option db_log_dir, which points the log dir. Inside that dir, in order to make log names unique, the log file name is prefixed with the leveldb data dir absolute path.

- LevelDB patch for FreeBSD. This resolves Issue 22. Contributed by dforsythe (thanks!). - Removing Chromium-specific files. They are now going to live in the Chromium repository. - Adding a benchmark page comparing LevelDB performance to SQLite and Kyoto Cabinet's TreeDB, along with code to generate the benchmarks. Thanks to Kevin Tseng for compiling the benchmarks, and Scott Hess and Mikio Hirabayashi for their help and advice. git-svn-id: https://leveldb.googlecode.com/svn/trunk@40 62dab493-f737-651d-591e-8d6aee1b9529

- Removed one copy of an uncompressed block contents changing the signature of Snappy_Uncompress() so it uncompresses into a flat array instead of a std::string. Speeds up readrandom ~10%. - Instead of a combination of Env/WritableFile, we now have a Logger interface that can be easily overridden applications that want to supply their own logging. - Separated out the gcc and Sun Studio parts of atomic_pointer.h so we can use 'asm', 'volatile' keywords for Sun Studio. git-svn-id: https://leveldb.googlecode.com/svn/trunk@39 62dab493-f737-651d-591e-8d6aee1b9529

Change atomic_pointer.h to prefer a memory barrier based implementation over a <cstdatomic> based implementation for the following reasons: (1) On a x86-32-bit gcc-4.4 build, <ctdatomic> was corrupting the AtomicPointer. (2) On a x86-64-bit gcc build, a <ctstdatomic> based acquire-load takes ~15ns as opposed to the ~1ns for a memory-barrier based implementation. Fixes issue 9 (corruption_test fails) http://code.google.com/p/leveldb/issues/detail?id=9 Fixes issue 16 (CorruptionTest.MissingDescriptor fails) http://code.google.com/p/leveldb/issues/detail?id=16 git-svn-id: https://leveldb.googlecode.com/svn/trunk@36 62dab493-f737-651d-591e-8d6aee1b9529

This revision adds two major changes: 1. build_detect_platform which generates build_config.mk with platform-dependent flags for the build process 2. /port/atomic_pointer.h with anAtomicPointerimplementation for platforms without <cstdatomic> Some of this code is loosely based on patches submitted to the LevelDB mailing list at https://groups.google.com/forum/#!forum/leveldb Tip of the hat to Dave Smith and Edouard A, who both sent patches. The presence of Snappy (http://code.google.com/p/snappy/) and cstdatomic are now both detected in the build_detect_platform script (1.) which gets executing during make. For (2.), instead of broadly importing atomicops_* from Chromium or the Google performance tools, we chose to just implement AtomicPointer and the limited atomic load and store operations it needs. This resulted in much less code and fewer files - everything is contained in atomic_pointer.h. git-svn-id: https://leveldb.googlecode.com/svn/trunk@34 62dab493-f737-651d-591e-8d6aee1b9529

- Implemented Get() directly instead of building on top of a full merging iterator stack. This speeds up the "readrandom" benchmark by up to 15-30%. - Fixed an opensource compilation problem. Added --db=<name> flag to control where the database is placed. - Automatically compact a file when we have done enough overlapping seeks to that file. - Fixed a performance bug where we would read from at least one file in a level even if none of the files overlapped the key being read. - Makefile fix for Mac OSX installations that have XCode 4 without XCode 3. - Unified the two occurrences of binary search in a file-list into one routine. - Found and fixed a bug where we would unnecessarily search the last file when looking for a key larger than all data in the level. - A fix to avoid the need for trivial move compactions and therefore gets rid of two out of five syncs in "fillseq". - Removed the MANIFEST file write when switching to a new memtable/log-file for a 10-20% improvement on fill speed on ext4. - Adding a SNAPPY setting in the Makefile for folks who have Snappy installed. Snappy compresses values and speeds up writes. git-svn-id: https://leveldb.googlecode.com/svn/trunk@32 62dab493-f737-651d-591e-8d6aee1b9529
