f3f13973 - Separate Env tests from PosixEnv tests.

Wed, 01 Mar 2017 20:05:47 +0000

Separate Env tests from PosixEnv tests.env_test.cc defines EnvPosixTest which tests the Env implementation returned by Env::Default(). The naming is a bit unfortunate, as the tests in env_test.cc are written against the Env contract, and therefore are applicable to any Env implementation. An instance of the confusion caused by the naming is [] which added a dependency from env_test.cc to EnvPosixTestHelper, which is closely coupled to EnvPosix.This change disentangles EnvPosix-specific test code into a env_posix_test.cc file. The code there uses EnvPosixTestHelper and specifically targets the EnvPosix implementation. env_test.cc now implements EnvTest, and contains tests that are also applicable to other ports, which may define their own Env implementation.-------------Created by MOE: https://github.com/google/moeMOE_MIGRATED_REVID=148914642 List of files: /leveldb-1.20/Makefile

ea175e28 - Implement support for Intel crc32 instruction (SSE 4.2)

Mon, 27 Feb 2017 22:29:18 +0000

Implement support for Intel crc32 instruction (SSE 4.2)This change authored by vadimskipin and submitted via: https://github.com/google/leveldb/pull/309Changes made to support iOS builds and other architectureswithout support for SSE 4.2.db_bench reports original crc32 speed at: crc32c : 3.610 micros/op; 1082.0 MB/s (4K per op)with this change performance has increased to: crc32c : 0.843 micros/op; 4633.6 MB/s (4K per op)-------------Created by MOE: https://github.com/google/moeMOE_MIGRATED_REVID=148694935 List of files: /leveldb-1.20/Makefile

adbe3eb0 - Putting build artifacts in subdirectory.

Fri, 29 Jan 2016 23:58:37 +0000

Putting build artifacts in subdirectory.1. Object files, libraries, and compiled executables are put into subdirectories.2. The shared library is linked from individual object files. This provides for greater parallelism on large desktops while at the same time making for easier builds on small (i.e. embedded) systems. Fixes issue #279.3. One program, db_bench, is compiled using the shared library.4. The source file for "leveldbutil" was renamed from leveldb_main.cc to leveldbutil.cc. This provides for simpler makefile rules.5. Because all targets placed the library (libleveldb.a) at the top level, the last platform built (desktop/device) always overwrote any prior artifact.-------------Created by MOE: https://github.com/google/moeMOE_MIGRATED_REVID=113407013 List of files: /leveldb-1.20/Makefile

889de31a - Let LevelDB use xcrun to determine Xcode.app path instead of using a hardcoded path.

ac1d69da - LevelDB now attempts to reuse the preceding MANIFEST and log file when re-opened.

Thu, 11 Dec 2014 16:13:18 +0000

LevelDB now attempts to reuse the preceding MANIFEST and log file when re-opened.(Based on a suggestion by cmumford.)"open" benchmark on my workstation speeds up significantly since wecan now avoid three fdatasync calls and a compaction per open: Before: ~80000 microseconds After: ~130 microsecondsDetails:(1) Added Options::reuse_logs (currently defaults to false) to controlnew behavior. The intention is to change the default to true after somebaking.(2) Added Env::NewAppendableFile() whose default implementation returnsa not-supported error.(3) VersionSet::Recovery attempts to reuse the MANIFEST from whichit is recovering.(4) DBImpl recovery attempts to reuse the last log file and memtable.(5) db_test.cc now tests a new configuration that sets reuse_logs to true.(6) fault_injection_test also tests a reuse_logs==true config.(7) Added a new recovery_test.

b234f65b - Added a new fault injection test.

Thu, 11 Dec 2014 15:59:38 +0000

Added a new fault injection test.This test is intended to ensure leveldb properly detects and recovers fromfaults - specifically unwritten file data lost as a result of a system reset. List of files: /leveldb-1.20/Makefile

803d6920 - Release 1.18

Tue, 16 Sep 2014 21:19:52 +0000

Release 1.18Changes are:* Update version number to 1.18* Replace the basic fprintf call with a call to fwrite in order to work around the apparent compiler optimization/rewrite failure that we are seeing with the new toolchain/iOS SDKs provided with Xcode6 and iOS8.* Fix ALL the header guards.* Createed a README.md with the LevelDB project description.* A new CONTRIBUTING file.* Don't implicitly convert uint64_t to size_t or int. Either preserve it as uint64_t, or explicitly cast. This fixes MSVC warnings about possible value truncation when compiling this code in Chromium.* Added a DumpFile() library function that encapsulates the guts of the "leveldbutil dump" command. This will allow clients to dump data to their log files instead of stdout. It will also allow clients to supply their own environment.* leveldb: Remove unused function 'ConsumeChar'.* leveldbutil: Remove unused member variables from WriteBatchItemPrinter.* OpenBSD, NetBSD and DragonflyBSD have _LITTLE_ENDIAN, so define PLATFORM_IS_LITTLE_ENDIAN like on FreeBSD. This fixes: * issue #143 * issue #198 * issue #249* Switch from to . The former never made it into the standard and doesn't exist in modern gcc versions at all. The later contains everything that leveldb was using from the former. This problem was noticed when porting to Portable Native Client where no memory barrier is defined. The fact that is missing normally goes unnoticed since memory barriers are defined for most architectures.* Make Hash() treat its input as unsigned. Before this change LevelDB files from platforms with different signedness of char were not compatible. This change fixes: issue #243* Verify checksums of index/meta/filter blocks when paranoid_checks set.* Invoke all tools for iOS with xcrun. (This was causing problems with the new XCode 5.1.1 image on pulse.)* include only once, and fix the following linter warning: "Found C system header after C++ system header"* When encountering a corrupted table file, return Status::Corruption instead of Status::InvalidArgument.* Support cygwin as build platform, patch is from https://code.google.com/p/leveldb/issues/detail?id=188* Fix typo, merge patch from https://code.google.com/p/leveldb/issues/detail?id=159* Fix typos and comments, and address the following two issues: * issue #166 * issue #241* Add missing db synchronize after "fillseq" in the benchmark.* Removed unused variable in SeekRandom: value (issue #201) List of files: /leveldb-1.20/Makefile

e353fbc7 - Release LevelDB 1.17

Thu, 01 May 2014 20:43:12 +0000

Release LevelDB 1.17- Cleanup: delete unused IntSetToString It was added in http://cr/19491949 (and was referenced at the time). The last reference was removed in http://cr/19507363. This fixes warning/error with pre-release crosstoolv18: 'std::string leveldb::{anonymous}::IntSetToString(const std::set&)' defined but not used [-Werror=unused-function]- Added arm64 and and armv7s to IOS build as suggested on leveldb mailing list.- Changed local variable type from int to size_t This eliminates compiler warning/error and resolves https://code.google.com/p/leveldb/issues/detail?id=140 List of files: /leveldb-1.20/Makefile

0cfb990d - Release LevelDB 1.15

Tue, 10 Dec 2013 18:36:31 +0000

Release LevelDB 1.15- 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 List of files: /leveldb-1.20/Makefile
