| 03:43 | Change the default page size for new database files to 4096 (from 1024). Except, when building the testfixture, preserve the legacy page size. Also fix a comment on SQLITE_MAX_ATTACHED. check-in: 2e8a9ca9 user: drh tags: trunk | |
| 03:20 | Detect the presence of pread()/pwrite() system calls on unix systems and use them if available. check-in: 82cbf5ad user: drh tags: trunk | |
| 03:14 | Further fixes to the pread()/pwrite() enabling logic. Closed-Leaf check-in: 38fb54e7 user: drh tags: pread | |
| 02:59 | Add the test_bestindex.c file to Makefile.in and Makefile.msc so that "make test" will work again. check-in: 6ec6b6a9 user: drh tags: trunk | |
