| -# Usage: do_malloc_test <test number> <options...>
|
| -#
|
| -# The first argument, <test number>, is an integer used to name the
|
| -# tests executed by this proc. Options are as follows:
|
| -#
|
| -# -tclprep TCL script to run to prepare test.
|
| -# -sqlprep SQL script to run to prepare test.
|
| -# -tclbody TCL script to run with malloc failure simulation.
|
| -# -sqlbody TCL script to run with malloc failure simulation.
|
| -# -cleanup TCL script to run after the test.
|
| -#
|
| -# This command runs a series of tests to verify SQLite's ability
|
| -# to handle an out-of-memory condition gracefully. It is assumed
|
| -# that if this condition occurs a malloc() call will return a
|
| -# NULL pointer. Linux, for example, doesn't do that by default. See
|
| -# the "BUGS" section of malloc(3).
|
| -#
|
| -# Each iteration of a loop, the TCL commands in any argument passed
|
| -# to the -tclbody switch, followed by the SQL commands in any argument
|
| -# passed to the -sqlbody switch are executed. Each iteration the
|
| -# Nth call to sqliteMalloc() is made to fail, where N is increased
|
| -# each time the loop runs starting from 1. When all commands execute
|
| -# successfully, the loop ends.
