| ||
| 16:18 | [c5d2b974] part of check-in [a80ae2c9] Dozens and dozens of typo fixes in comments. This change adds no value to the end product and is disruptive, so it is questionable whether or not it will ever land on trunk. (check-in: [a80ae2c9] user: drh branch: typos, size: 9098) | |
|
2017-03-21
| ||
| 20:17 | [c12a4253] part of check-in [055b36f1] New simplified memory initialization for MacOS. (check-in: [055b36f1] user: drh branch: trunk, size: 9098) | |
|

| ||
| 13:59 | [79bf195f] part of check-in [4e6a03d9] Only do the specialized MacOS single-core zone_malloc initialization if compiled with the SQLITE_MIGHT_BE_SINGLE_CORE flag. This avoids a (harmless) warning about OSAtomicCompareAndSwapPtrBarrier() being deprecated. (check-in: [4e6a03d9] user: drh branch: trunk, size: 9909) | |
|
2017-02-08
