| 07:25 | Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM. (check-in: 456bd5c6 user: dan tags: trunk) | |
| 06:13 | Changes to exclusive2.test to make it more deterministic. (check-in: 84b0c2bc user: dan tags: trunk) | |
| 00:07 | Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order to distinguish it from PGroup.mxPinned. Fix the computation of n90pct so that it does not overflow adversely on excessively large cache sizes. (check-in: c85202ba user: drh tags: trunk) | |
