Hans Wennborg	36a5f8ed7f	A number of fixes: ... - 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)	2011-10-31 17:22:06 +00:00
Hans Wennborg	26db4d971a	Sync with upstream @24213649. ... 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	2011-09-26 17:37:09 +01:00
Hans Wennborg	213a68eb68	Sync with upstream @23860137. ... 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.)	2011-09-12 10:21:10 +01:00
