2017-02-17
| ||
| 23:52 | Fix the #endif location for an #ifndef SQLITE_UNTESTABLE macro in the command-line shell. check-in: 8cc9d74c user: drh tags: trunk | |
| 02:04 | Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. check-in: 218b2bbb user: drh tags: trunk | |
| 01:43 | Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. check-in: 8a03be1d user: drh tags: trunk | |
|
2017-02-16
| ||

| 18:30 | Minor enhancement to mutex tracing on Win32. check-in: 830b9235 user: mistachkin tags: trunk | |

Fix a bug in R-Tree that occurs when compiling on a known little-endian machine without the use of intrinsic byteswapping functions. check-in: 798fb9d7 user: drh tags: trunk | |
