Fix threadtest3 so that it builds using the autoconf build system. (check-in: d96de532cc user: dan tags: trunk)
11:51

01:48
A unix VFS change replaces fsync() with fstat() when using SQLITE_NO_SYNC, so set PRAGMA synchronous=OFF in the sysfault-3 test to avoid erroneously causing errors in xSync. (check-in: 4f7f355021 user: drh tags: trunk)
2015-12-02
20:53

19:15
Fix the threadtest3 test program so that it works with VFSes that omit the xCurrentTime() method and supply only xCurrentTimeInt64(). (check-in: 3b155855f3 user: drh tags: trunk)
18:17
Fix the schemalint.tcl script to handle identifiers that require quoting. (check-in: 451e0fafbe user: dan tags: schemalint)
