// This file implements a simple standalone program used to test whether
|
|
// or not the SQLite library is threadsafe.
|
|
//
|
|
// Testing the thread safety of SQLite is difficult because there are very
|
|
// few places in the code that are even potentially unsafe, and those
|
|
// places execute for very short periods of time. So even if the library
|
|
// is compiled with its mutexes disabled, it is likely to work correctly
|
|
// in a multi-threaded program most of the time.
|
|
//
|
|
// This file is NOT part of the standard SQLite library. It is used for
|
|
// testing only.
