 | |
| ** This is a program used for testing SQLite, and specifically for testing
 | |
| ** the ability of independent processes to access the same SQLite database
 | |
| ** concurrently.
 | |
| **
 | |
| ** Compile this program as follows:
 | |
| **
 | |
| **    gcc -g -c -Wall sqlite3.c $(OPTS)
 | |
| **    gcc -g -o mptest mptest.c sqlite3.o $(LIBS)
 | |
| **
 | |
| ** Recommended options:
 | |
| **
 | |
| **    -DHAVE_USLEEP
 | |
| **    -DSQLITE_NO_SYNC
 | |
| **    -DSQLITE_THREADSAFE=0
 | |
| **    -DSQLITE_OMIT_LOAD_EXTENSION
 | |
| **
 | |
| ** Run like this:
 | |
| **
 | |
| **     ./mptest $database $script
 | |
| **
 | |
| ** where $database is the database to use for testing and $script is a
 | |
| ** test script.
