| 20:17 | New simplified memory initialization for MacOS. file: [c12a4253] check-in: [055b36f1] user: drh branch: trunk, size: 9098 | |
|
2017-03-18
| ||
| 13:59 | 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. file: [79bf195f] check-in: [4e6a03d9] user: drh branch: trunk, size: 9909 | |
|
2017-02-08

|
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: [abe6ee46] check-in: [9e92a5ed] user: drh branch: trunk, size: 9198 | |

|
2012-01-18

| 12:46 | Add the SQLITE_WITHOUT_MSIZE and SQLITE_WITHOUT_ZONEMALLOC macros in mem1.c to disable the use of _msize() on windows and the zone memory allocator on Apple products, respectively. file: [3137fd0e] check-in: [238e35a4] user: drh branch: trunk, size: 8634 | |

| ||
| 04:33 | Use the ROUND8() macro to round an integer up to the nearest multiple of 8 and ROUNDDOWN8() macro to round down to the nearest multiple of 8. This is a cosmetic change. (CVS 6372) file: [e6d5c239] check-in: [db1d4d2f] user: danielk1977 branch: trunk, size: 3711 | |
|
2008-12-10

|
2008-03-18

|
2007-09-02
| ||
| 17:50 | Fix function name typo in mem1.c. This bug managed to make it into the tree because the code in mem1.c is only compiled when the -DSQLITE_MEMDEBUG compile-time option is omitted.
