| 19:56 | Add APIs to allow fts5 to be augmented with ranking and snippet functions. Does not work yet. check-in: a235305d42 user: dan tags: matchinfo | |
| 19:02 | Add the sqlite4_kvfactory typedef to the interface and use that typedef throughout the implementation. This check-in also includes some unrelated cleanup of the sqlite4.h file. check-in: a2630e5d90 user: drh tags: trunk | |
| 18:41 | Fix a memory leak in fts5.c. check-in: 7bc0e58875 user: dan tags: trunk | |
| 18:24 | Add files "mem.h" and "mem.c". These are not currently linked into the build and have never been tested. At the moment they should be considered working notes, not real code. The code contained in these files might get folded into the build, or it might be deleted. check-in: e9efc61a51 user: drh tags: trunk | |
