Currently, embedders have to build a binary for each test file. After this CL, embedders can still choose to have a binary for each test file, by linking each test file with a googletest target that includes main() (usually "gtest_main"). Embedders can also choose to build a single binary for almost all test files, and link with a googletest target that includes main(). The latter is more convenient for projects that have very few test binaries, like Chromium. PiperOrigin-RevId: 419470798

Other files opened by leveldb are not affected because by and large they are using CreateFileA, which does not allow inheritance when lpSecurityAttributes is null (ref: https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilea) However, fopen() _does_ allow inheritance, and it needs to be expressly disabled. https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/fopen-wfopen?view=msvc-160

As reported in Github issue #339, it is incorrect to split the same user key across multiple compacted files since it causes tombstones/newer-versions to be dropped, thereby exposing obsolete data. There was a fix for #339, but it ended up not fully fixing the problem. (It checked for boundary problems in the first level being compacted, but not the second). This problem was revealed by Github issue 887. We now adjust boundaries to avoid splitting user keys in both the first level and the second level. PiperOrigin-RevId: 374921082

It is additionally beneficial with larger block sizes and keys with common prefixes. Add a benchmark "seekordered" to db_bench that reuses iterators across increasing seeks. Add support to the benchmark to count comparisons made and to support common key prefix length. Change benchmark random seeds to be reproducible for entire benchmark suite executions but unique for threads in different benchmarks runs. This changes a benchmark suite of readrandom,seekrandom from having a 100% found ratio as previously it had the same seed used for fillrandom. ./db_bench --benchmarks=fillrandom,compact,seekordered --block_size=262144 --comparisons=1 --key_prefix=100 without this change (though with benchmark changes): seekrandom : 55.309 micros/op; (631820 of 1000000 found) Comparisons: 27001049 seekordered : 1.732 micros/op; (631882 of 1000000 found) Comparisons: 26998402 with this change: seekrandom : 55.866 micros/op; (631820 of 1000000 found) Comparisons: 26952143 seekordered : 1.686 micros/op; (631882 of 1000000 found) Comparisons: 25549369 For ordered seeking, this is a reduction of 5% comparisons and a 3% speedup. For random seeking (with single use iterators) the comparisons and speed are less than 1% and likely noise. PiperOrigin-RevId: 351149832
