-*************************************************************************
-** This file contains code to implement a fault-injector used for
-** testing and verification of SQLite.
-**
-** Subsystems within SQLite can call sqlite3FaultStep() to see if
-** they should simulate a fault.  sqlite3FaultStep() normally returns
-** zero but will return non-zero if a fault should be simulated.
-** Fault injectors can be used, for example, to simulate memory
-** allocation failures or I/O errors.
-**
-** The fault injector is omitted from the code if SQLite is
-** compiled with -DSQLITE_OMIT_FAULTINJECTOR=1.  There is a very
-** small performance hit for leaving the fault injector in the code.
-** Commerical products will probably want to omit the fault injector
-** from production builds.  But safety-critical systems who work
-** under the motto "fly what you test and test what you fly" may
-** choose to leave the fault injector enabled even in production.
