2011-08-16Bugfixes for iterator and documentation.gabor@google.com
- Fix bug in Iterator::Prev where it would return the wrong key. Fixes issues 29 and 30. - Added a tweak to testharness to allow running just some tests. - Fixing two minor documentation errors based on issues 28 and 25. - Cleanup; fix namespaces of export-to-C code. Also fix one "const char*" vs "char*" mismatch. git-svn-id: http://leveldb.googlecode.com/svn/trunk@48 62dab493-f737-651d-591e-8d6aee1b9529

2011-08-05C binding for leveldb, better readseq benchmark for SQLite.gabor@google.com
- Added a C binding for LevelDB. May be useful as a stable ABI that can be used by programs that keep leveldb in a shared library, or for JNI API. - Replaced SQLite's readseq benchmark to a more efficient version. SQLite readseq speeds increased by about a factor of 2x from the previous version. Also updated benchmark page to reflect readseq speed up. git-svn-id: http://leveldb.googlecode.com/svn/trunk@46 62dab493-f737-651d-591e-8d6aee1b9529
2011-07-29Improved benchmark, fixed bugs and SQLite parameters.gabor@google.com
- Based on suggestions on the sqlite-users mailing list, we removed the superfluous index on the primary key for SQLite's benchmarks, and turned write-ahead logging ("WAL") on. This led to performance improvements for SQLite. - Based on a suggestion by Florian Weimer on the leveldb mailing list, we disabled hard drive write-caching via hdparm when testing synchronous writes. This led to performance losses for LevelDB and Kyoto TreeDB. - Fixed a mistake in 2.A.->Random where the bar sizes were switched for Kyoto TreeDB and SQLite. git-svn-id: http://leveldb.googlecode.com/svn/trunk@45 62dab493-f737-651d-591e-8d6aee1b9529

2011-07-27Adding FreeBSD support, removing Chromium files, adding benchmark.gabor@google.com
- 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: http://leveldb.googlecode.com/svn/trunk@40 62dab493-f737-651d-591e-8d6aee1b9529
2011-07-21Speed up Snappy uncompression, new Logger interface.gabor@google.com
- 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: http://leveldb.googlecode.com/svn/trunk@39 62dab493-f737-651d-591e-8d6aee1b9529
2011-07-19Sun Studio support, and fix for test related memory fixes.gabor@google.com

2011-07-15Small tweaks and bugfixes for Issue 18 and 19.gabor@google.com
Slight tweak to the no-overlap optimization: only push to level 2 to reduce the amount of wasted space when the same small key range is being repeatedly overwritten. Fix for Issue 18: Avoid failure on Windows by avoiding deletion of lock file until the end of DestroyDB(). Fix for Issue 19: Disregard sequence numbers when checking for overlap in sstable ranges. This fixes issue 19: when writing the same key over and over again, we would generate a sequence of sstables that were never merged together since their sequence numbers were disjoint. Don't ignore map/unmap error checks. Miscellaneous fixes for small problems Sanjay found while diagnosing issue/9 and issue/16 (corruption_testr failures). - log::Reader reports the record type when it finds an unexpected type. - log::Reader no longer reports an error when it encounters an expected zero record regardless of the setting of the "checksum" flag. - Added a missing forward declaration. - Documented a side-effects of larger write buffer sizes (longer recovery time). git-svn-id: http://leveldb.googlecode.com/svn/trunk@37 62dab493-f737-651d-591e-8d6aee1b9529
2011-06-30Fixed a snappy compression wrapper bug (passing wrong variable).gabor@google.com
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: http://leveldb.googlecode.com/svn/trunk@36 62dab493-f737-651d-591e-8d6aee1b9529

2011-06-29Platform detection during build, plus compatibility patches for machines ↵gabor@google.com
without <cstdatomic>. 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: http://leveldb.googlecode.com/svn/trunk@34 62dab493-f737-651d-591e-8d6aee1b9529

2011-06-22A number of smaller fixes and performance improvements:gabor@google.com
- 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: http://leveldb.googlecode.com/svn/trunk@32 62dab493-f737-651d-591e-8d6aee1b9529
2011-06-07sync with upstream @21706995hans@chromium.org
Fixed race condition reported by Dave Smit (dizzyd@dizzyd,com) on the leveldb mailing list. We were not signalling waiters after a trivial move from level-0. The result was that in some cases (hard to reproduce), a write would get stuck forever waiting for the number of level-0 files to drop below its hard limit. The new code is simpler: there is just one condition variable instead of two, and the condition variable is signalled after every piece of background work finishes. Also, all compaction work (including for manual compactions) is done in the background thread, and therefore we can remove the "compacting_" variable. git-svn-id: http://leveldb.googlecode.com/svn/trunk@31 62dab493-f737-651d-591e-8d6aee1b9529
