# This AWK script reads the output of testfixture when compiled for memory
|
|
# debugging. It generates SQL commands that can be fed into an sqlite
|
|
# instance to determine what memory is never freed. A typical usage would
|
|
# be as follows:
|
|
#
|
|
# make -f memleak.mk fulltest 2>mem.out
|
|
# awk -f ../sqlite/tool/memleak2.awk mem.out | ./sqlite :memory:
|
|
#
|
|
# The job performed by this script is the same as that done by memleak.awk.
|
|
# The difference is that this script uses much less memory when the size
|
|
# of the mem.out file is huge.
|
|
