* Switch from C headers to C++ headers.Victor Costan2020-04-291-2/+1
| | | | | | | | | | | | | | | This CL makes the following substitutions. * assert.h -> cassert * math.h -> cmath * stdarg.h -> cstdarg * stddef.h -> cstddef * stdint.h -> cstdint * stdio.h -> cstdio * stdlib.h -> cstdlib * string.h -> cstring PiperOrigin-RevId: 309080151
* Correct class/structure declaration order.Chris Mumford2019-05-031-2/+2
| | | | | | | | | | | | | 1. Correct the class/struct declaration order to be IAW the Google C++ style guide[1]. 2. For non-copyable classes, switched from non-implemented private methods to explicitly deleted[2] methods. 3. Minor const and member initialization fixes.

* Format all files IAW the Google C++ Style Guide.Chris Mumford2019-05-021-10/+7
| | | | | | Use clang-format to correct formatting to be in agreement with the [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html). Doing this simplifies the process of accepting changes. Also fixed a few warnings flagged by clang-tidy. PiperOrigin-RevId: 246350737

* Extend thread safety annotations.costan2018-03-161-2/+2
| | | | | | | | | | | | | | | | | | | This CL makes it easier to reason about thread safety by: 1) Adding Clang thread safety annotations according to comments. 2) Expanding a couple of variable names, without adding extra lines of code. 3) Adding const in a couple of places. 4) Replacing an always-non-null const pointer with a reference. 5) Fixing style warnings in the modified files. This CL does not annotate the DBImpl members that claim to be protected by the instance mutex, but are accessed without the mutex being held. Those members (and their unprotected accesses) will be addressed in future CLs. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=189354657
* Added bloom filter support.v1.4Sanjay Ghemawat2012-04-171-0/+11
| | | | | | | | | | | | | | | | | | | | 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.
* A number of fixes:Hans Wennborg2011-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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)
