#
# Short note on generating suppressions:
#
# See the valgrind documentation for a description of suppressions. The easiest
# way to generate a suppression expression is by using the valgrind
# --gen-suppressions option. To do that you have to figure out how to run the
# test in question.
#
# If you do "test.py -v -g -s <suitename> then test.py will output most of what
# you need. For example, if you are getting a valgrind error in the
# devices-mesh-dot11s-regression test suite, you can run:
#
# ./test.py -v -g -s devices-mesh-dot11s-regression
#
# You should see in the verbose output something that looks like:
#
# Synchronously execute valgrind --suppressions=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/testpy.supp
# --leak-check=full --error-exitcode=2 /home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/build/debug/utils/test-runner
# --suite=devices-mesh-dot11s-regression --basedir=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev
# --tempdir=testpy-output/2010-01-12-22-47-50-CUT
# --out=testpy-output/2010-01-12-22-47-50-CUT/devices-mesh-dot11s-regression.xml
#
# You need to pull out the useful pieces, and so could run the following to
# reproduce your error:
#
# valgrind --suppressions=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/testpy.supp
# --leak-check=full --error-exitcode=2 /home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/build/debug/utils/test-runner
# --suite=devices-mesh-dot11s-regression --basedir=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev
# --tempdir=testpy-output
#
# Hint: Use the first part of the command as is, and point the "tempdir" to
# somewhere real. You don't need to specify an "out" file.
#
# When you run the above command you should see your valgrind error. The
# suppression expression(s) can be generated by adding the --gen-suppressions=yes
# option to valgrind. Use something like:
#
# valgrind --gen-suppressions=yes --suppressions=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/testpy.supp
# --leak-check=full --error-exitcode=2 /home/craigdo/repos/ns-3-allinone-dev/ns-3-dev/build/debug/utils/test-runner
# --suite=devices-mesh-dot11s-regression --basedir=/home/craigdo/repos/ns-3-allinone-dev/ns-3-dev
# --tempdir=testpy-output
#
# Now when valgrind detects an error it will ask:
#
# ==27235== ---- Print suppression ? --- [Return/N/n/Y/y/C/c] ----
#
# to which you just enter 'y'<ret>.
#
# You will be provided with a suppression expression that looks something like
# the following:
# {
# <insert_a_suppression_name_here>
# Memcheck:Addr8
# fun:_ZN3ns36dot11s15HwmpProtocolMac8SendPreqESt6vectorINS0_6IePreqESaIS3_EE
# fun:_ZN3ns36dot11s15HwmpProtocolMac10SendMyPreqEv
# fun:_ZN3ns36dot11s15HwmpProtocolMac18RequestDestinationENS_12Mac48AddressEjj
# ...
# the rest of the stack frame
# ...
# }
#
# You need to add a supression name which will only be printed out by valgrind in
# verbose mode (but it needs to be there in any case). The entire stack frame is
# shown to completely characterize the error, but in most cases you won't need
# all of that info. For example, if you want to turn off all errors that happen
# when the function (fun:) is called, you can just delete the rest of the stack
# frame. You can also use wildcards to make the mangled signatures more readable.
#
# I added the following to the testpy.supp file for this particular error:
#
# {
# Supress invalid read size errors in SendPreq() when using HwmpProtocolMac
# Memcheck:Addr8
# fun:*HwmpProtocolMac*SendPreq*
# }
#
# Now, when you run valgrind the error will be suppressed.
