|
2017-02-15

| 15:09 | Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. file: [ca8440ed] check-in: [810d2932] user: drh branch: trunk, size: 42667 | |
|
2017-02-09

| 00:32 | Change the sqlite3Atoi64() routine so that it returns failure if not all of the input characters are consumed, even if it consumed all characters up to the first 0x00. This has no impact on external APIs as far as I can tell. file: [1d2f9cc9] check-in: [46d4ffff] user: drh branch: trunk, size: 39662 | |
|
2016-04-27
| ||
| 15:24 | More simplification of the sqlite3AtoF() routine. Add special comments to indicate branches that are for optimization purposes only and that give the correct answer even if always or never taken. file: [d0899604] check-in: [0065fe97] user: drh branch: trunk, size: 39446 | |

|
2016-02-25

2015-01-10
| ||
| 16:49 | Improvements to compile-time-option hygiene. Use "#if OPTION" instead of "#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work. Add the "Have-Not" configuration in releasetest.tcl which disables all of the "HAVE_component" compile-time options. file: [98a7627c] check-in: [9e92a5ed] user: drh branch: trunk, size: 36197 | |
