2011-11-30Makefile fixes for systems with $CXX other than g++.hans@chromium.org
- Makefile: Use $(CXX) for compiling C++ files, don't override the environment's value of $CXX - build_detect_platform: use $CXX instead of g++. Based on bug report from Theo Schlossnagle: http://code.google.com/p/leveldb/issues/detail?id=46 (Sync with uptream at 25807040.) git-svn-id: http://leveldb.googlecode.com/svn/trunk@56 62dab493-f737-651d-591e-8d6aee1b9529
2011-11-14Pass system's CFLAGS, remove exit time destructor, sstable bug fix.hans@chromium.org
- Pass system's values of CFLAGS,LDFLAGS. Don't override OPT if it's already set. Original patch by Alessio Treglia <alessio@debian.org>: http://code.google.com/p/leveldb/issues/detail?id=27#c6 - Remove 1 exit time destructor from leveldb. See http://crbug.com/101600 - Fix problem where sstable building code would pass an internal key to the user comparator. (Sync with uptream at 25436817.) git-svn-id: http://leveldb.googlecode.com/svn/trunk@55 62dab493-f737-651d-591e-8d6aee1b9529
2011-10-31A number of fixes:hans@chromium.org
- Replace raw slice comparison with a call to user comparator. Added test for custom comparators. - Fix end of namespace comments. - Fixed bug in picking inputs for a level-0 compaction. When finding overlapping files, the covered range may expand as files are added to the input set. We now correctly expand the range when this happens instead of continuing to use the old range. For example, suppose L0 contains files with the following ranges: F1: a .. d F2: c .. g F3: f .. j and the initial compaction target is F3. We used to search for range f..j which yielded {F2,F3}. However we now expand the range as soon as another file is added. In this case, when F2 is added, we expand the range to c..j and restart the search. That picks up file F1 as well. This change fixes a bug related to deleted keys showing up incorrectly after a compaction as described in Issue 44. (Sync with upstream @25072954) git-svn-id: http://leveldb.googlecode.com/svn/trunk@54 62dab493-f737-651d-591e-8d6aee1b9529
2011-10-05A number of bugfixes:gabor@google.com
- Added DB::CompactRange() method. Changed manual compaction code so it breaks up compactions of big ranges into smaller compactions. Changed the code that pushes the output of memtable compactions to higher levels to obey the grandparent constraint: i.e., we must never have a single file in level L that overlaps too much data in level L+1 (to avoid very expensive L-1 compactions). Added code to pretty-print internal keys. - Fixed bug where we would not detect overlap with files in level-0 because we were incorrectly using binary search on an array of files with overlapping ranges. Added "leveldb.sstables" property that can be used to dump all of the sstables and ranges that make up the db state. - Removing post_write_snapshot support. Email to leveldb mailing list brought up no users, just confusion from one person about what it meant. - Fixing static_cast char to unsigned on BIG_ENDIAN platforms. Fixes Issue 35 and Issue 36. - Comment clarification to address leveldb Issue 37. - Change license in posix_logger.h to match other files. - A build problem where uint32 was used instead of uint32_t. Sync with upstream @24408625 git-svn-id: http://leveldb.googlecode.com/svn/trunk@53 62dab493-f737-651d-591e-8d6aee1b9529
2011-09-26Sync with upstream @24213649.hans@chromium.org
Adding GNU/kFreeBSD support. As requested here: http://code.google.com/p/leveldb/issues/detail?id=38 Use uint64_t instead of size_t in MemEnvTest. As pointed out at http://code.google.com/p/leveldb/issues/detail?id=41 git-svn-id: http://leveldb.googlecode.com/svn/trunk@52 62dab493-f737-651d-591e-8d6aee1b9529
2011-09-15Sync with upstream @23860137.gabor@google.com
Fix GCC -Wshadow warnings in LevelDB's public header files, reported by Dustin. Add in-memory Env implementation (helpers/memenv/*). This enables users to create LevelDB databases in-memory. Initialize ShardedLRUCache::last_id_ to zero. This fixes a Valgrind warning. (Also delete port/sha1_* which were removed upstream some time ago.) git-svn-id: http://leveldb.googlecode.com/svn/trunk@51 62dab493-f737-651d-591e-8d6aee1b9529
2011-09-01Bugfixes: for Get(), don't hold mutex while writing log.gabor@google.com
- Fix bug in Get: when it triggers a compaction, it could sometimes mark the compaction with the wrong level (if there was a gap in the set of levels examined for the Get). - Do not hold mutex while writing to the log file or to the MANIFEST file. Added a new benchmark that runs a writer thread concurrently with reader threads. Percentiles ------------------------------ micros/op: avg median 99 99.9 99.99 99.999 max ------------------------------------------------------ before: 42 38 110 225 32000 42000 48000 after: 24 20 55 65 130 1100 7000 - Fixed race in optimized Get. It should have been using the pinned memtables, not the current memtables. git-svn-id: http://leveldb.googlecode.com/svn/trunk@50 62dab493-f737-651d-591e-8d6aee1b9529
2011-08-22Bugfix for issue 33; reduce lock contention in Get(), parallel benchmarks.gabor@google.com
- Fix for issue 33 (non-null-terminated result from leveldb_property_value()) - Support for running multiple instances of a benchmark in parallel. - Reduce lock contention on Get(): (1) Do not hold the lock while searching memtables. (2) Shard block and table caches 16-ways. Benchmark for evaluating this change: $ db_bench --benchmarks=fillseq1,readrandom --threads=$n (fillseq1 is a small hack to make sure fillseq runs once regardless of number of threads specified on the command line). git-svn-id: http://leveldb.googlecode.com/svn/trunk@49 62dab493-f737-651d-591e-8d6aee1b9529
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

2011-07-15Small 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
