# Uncomment exactly one of the lines labelled (A), (B), and (C) below
# to switch between compilation modes.
Release 1.18 Changes 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 <cstdatomic> to <atomic>. 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 <cstdatomic> 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 <sys/stat.h> 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)

Platform detection during build, plus compatibility patches for machines 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: https://leveldb.googlecode.com/svn/trunk@34 62dab493-f737-651d-591e-8d6aee1b9529

Added bloom filter support. In particular, we add a new FilterPolicy class. An instance of this class can be supplied in Options when opening a database. If supplied, the instance is used to generate summaries of keys (e.g., a bloom filter) which are placed in sstables. These summaries are consulted by DB::Get() so we can avoid reading sstable blocks that are guaranteed to not contain the key we are looking for. This change provides one implementation of FilterPolicy based on bloom filters. Other changes: - Updated version number to 1.4. - Some build tweaks. - C binding for CompactRange. - A few more benchmarks: deleteseq, deleterandom, readmissing, seekrandom. - Minor .gitignore update.

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/moe MOE_MIGRATED_REVID=113407013

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/moe MOE_MIGRATED_REVID=148914642

Add LEVELDB_EXPORT macro to export public symbols. gcc defaults to exporting all symbols, but other linkers do not. Adding the LEVELDB_EXPORT macro allows a project to set LEVELDB_SHARED_LIBRARY when building/linking with leveldb as a shared library. This is to allow leveldb to be created as a shared library on all platforms support by Chrome and enables a fix for https://bugs.chromium.org/p/chromium/issues/detail?id=764810. This also has the benefit of reducing the shared library size from 418863 to 380367 bytes (64-bit Linux). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=171037148

Replace SSE-optimized CRC32C in POSIX port with external library. Maintaining a hardware-accelerated CRC32C implementation tailored for all modern platforms deserves a repository of its own. We extracted the implementation here into https://github.com/google/crc32c and improved it in that repository. This CL removes the SSE-optimized implementation from this codebase, and adds the ability to use the google/crc32c library, if it is present on the system. The benchmarks below show the performance impact of the change. In summary, open source builds that use the google/crc32c library can expect a 3x improvement in CRC32C throughput, whereas builds that do not use the library will see a 50% drop in CRC32C throughput. This translates in much smaller changes in overall leveldb performance.

Remove static initializer; fix endian-ness detection; fix build on various platforms; improve android port speed. Avoid static initializer by using a new portability interface for thread-safe lazy initialization. Custom ports will need to be extended to implement InitOnce/OnceType/LEVELDB_ONCE_INIT. Fix endian-ness detection (fixes Powerpc builds). Build related fixes: - Support platforms that have unversioned shared libraries. - Fix IOS build rules. Android improvements - Speed up atomic pointers - Share more code with port_posix. Do not spin in a tight loop attempting compactions if the file system is inaccessible (e.g., if kerberos tickets have expired or if it is out of space).

Add LEVELDB_EXPORT macro to export public symbols. gcc defaults to exporting all symbols, but other linkers do not. Adding the LEVELDB_EXPORT macro allows a project to set LEVELDB_SHARED_LIBRARY when building/linking with leveldb as a shared library. This is to allow leveldb to be created as a shared library on all platforms support by Chrome and enables a fix for https://bugs.chromium.org/p/chromium/issues/detail?id=764810. This also has the benefit of reducing the shared library size from 418863 to 380367 bytes (64-bit Linux). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=171037148

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/moe MOE_MIGRATED_REVID=113407013

LevelDB 1.13 Fix issues 77, 87, 182, 190. Additionally, fix the bug described in https://groups.google.com/d/msg/leveldb/yL6h1mAOc20/vLU64RylIdMJ where a large contiguous keyspace of deleted data was not getting compacted. Also fix a bug where options.max_open_files was not getting clamped properly.

Added bloom filter support. In particular, we add a new FilterPolicy class. An instance of this class can be supplied in Options when opening a database. If supplied, the instance is used to generate summaries of keys (e.g., a bloom filter) which are placed in sstables. These summaries are consulted by DB::Get() so we can avoid reading sstable blocks that are guaranteed to not contain the key we are looking for. This change provides one implementation of FilterPolicy based on bloom filters. Other changes: - Updated version number to 1.4. - Some build tweaks. - C binding for CompactRange. - A few more benchmarks: deleteseq, deleterandom, readmissing, seekrandom. - Minor .gitignore update.

C binding for leveldb, better readseq benchmark for SQLite. - 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: https://leveldb.googlecode.com/svn/trunk@46 62dab493-f737-651d-591e-8d6aee1b9529

Release 1.18 Changes 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 <cstdatomic> to <atomic>. 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 <cstdatomic> 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 <sys/stat.h> 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)

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 we can now avoid three fdatasync calls and a compaction per open: Before: ~80000 microseconds After: ~130 microseconds Details: (1) Added Options::reuse_logs (currently defaults to false) to control new behavior. The intention is to change the default to true after some baking. (2) Added Env::NewAppendableFile() whose default implementation returns a not-supported error. (3) VersionSet::Recovery attempts to reuse the MANIFEST from which it 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.

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/moe MOE_MIGRATED_REVID=113407013

A number of smaller fixes and performance improvements: - 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

C binding for leveldb, better readseq benchmark for SQLite. - 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: https://leveldb.googlecode.com/svn/trunk@46 62dab493-f737-651d-591e-8d6aee1b9529

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/moe MOE_MIGRATED_REVID=148914642

Add LEVELDB_EXPORT macro to export public symbols. gcc defaults to exporting all symbols, but other linkers do not. Adding the LEVELDB_EXPORT macro allows a project to set LEVELDB_SHARED_LIBRARY when building/linking with leveldb as a shared library. This is to allow leveldb to be created as a shared library on all platforms support by Chrome and enables a fix for https://bugs.chromium.org/p/chromium/issues/detail?id=764810.

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/moe MOE_MIGRATED_REVID=113407013

Add LEVELDB_EXPORT macro to export public symbols. gcc defaults to exporting all symbols, but other linkers do not. Adding the LEVELDB_EXPORT macro allows a project to set LEVELDB_SHARED_LIBRARY when building/linking with leveldb as a shared library. This is to allow leveldb to be created as a shared library on all platforms support by Chrome and enables a fix for https://bugs.chromium.org/p/chromium/issues/detail?id=764810.

C binding for leveldb, better readseq benchmark for SQLite. - 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: https://leveldb.googlecode.com/svn/trunk@46 62dab493-f737-651d-591e-8d6aee1b9529

Replace SSE-optimized CRC32C in POSIX port with external library. Maintaining a hardware-accelerated CRC32C implementation tailored for all modern platforms deserves a repository of its own. We extracted the implementation here into https://github.com/google/crc32c and improved it in that repository. This CL removes the SSE-optimized implementation from this codebase, and adds the ability to use the google/crc32c library, if it is present on the system. The benchmarks below show the performance impact of the change. In summary, open source builds that use the google/crc32c library can expect a 3x improvement in CRC32C throughput, whereas builds that do not use the library will see a 50% drop in CRC32C throughput. This translates in much smaller changes in overall leveldb performance.
