| 12:18 | Small size and performance improvement in pcacheManageDirtyList() by not zeroing the PgHdr.pDirtyNext and PgHdr.pDirtyPrev pointers for PgHdr objects that are not on the dirty list. (check-in: 919863b148 user: drh tags: trunk) | |
|
2017-08-31
| ||
| 21:11 | Clarify the documentation about "protected" versus "unprotected" sqlite3_value objects. No changes to code. (check-in: 4094a3410e user: drh tags: trunk) | |

| 20:21 | Faster memory allocation from lookaside by not trying to keep track of the number of outstanding allocations, and rather computing that value only when requested. (check-in: a06263f1ef user: drh tags: trunk) | |
| 17:52 | Add a Tcl script to run the performance tests described in README-server-edition.html. (check-in: 1b3df8ffc5 user: dan tags: server-process-edition) | |
