+#***********************************************************************
+# This file attempts to check the library in an out-of-memory situation.
+# When compiled with -DSQLITE_DEBUG=1, the SQLite library accepts a special
+# command (sqlite_malloc_fail N) which causes the N-th malloc to fail. This
+# special feature is used to see what happens in the library if a malloc
+# were to really fail due to an out-of-memory situation.

+
+# 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.
