#
# 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/ns3-dev-test-runner-debug
# --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/ns3-dev-test-runner-debug
# --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/ns3-dev-test-runner-debug
# --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:
#
# {
# Suppress invalid read size errors in SendPreq() when using HwmpProtocolMac
# Memcheck:Addr8
# fun:*HwmpProtocolMac*SendPreq*
# }
#
# Now, when you run valgrind the error will be suppressed.

# If we're not running an example, we're running a test suite.

# that was written to a temporary file to avoid collisions.
#
# Now that we are executing sequentially in the main thread, we can
# concatenate the contents of the associated temp file to the main
# results file and remove that temp file.
#
# One thing to consider is that a test suite can crash just as
# well as any other program, so we need to deal with that
# possibility as well. If it ran correctly it will return 0
# if it passed, or 1 if it failed. In this case, we can count
# on the results file it saved being complete. If it crashed, it
# will return some other code, and the file should be considered
# corrupt and useless. If the suite didn't create any XML, then
# we're going to have to do it ourselves.
#
# Another issue is how to deal with a valgrind error. If we run
# a test suite under valgrind and it passes, we will get a return
# code of 0 and there will be a valid xml results file since the code
# ran to completion. If we get a return code of 1 under valgrind,
# the test case failed, but valgrind did not find any problems so the
# test case return code was passed through. We will have a valid xml
# results file here as well since the test suite ran. If we see a
# return code of 2, this means that valgrind found an error (we asked
# it to return 2 if it found a problem in run_job_synchronously) but
# the suite ran to completion so there is a valid xml results file.
# If the suite crashes under valgrind we will see some other error
# return code (like 139). If valgrind finds an illegal instruction or
# some other strange problem, it will die with its own strange return
# code (like 132). However, if the test crashes by itself, not under
# valgrind we will also see some other return code.
#
# If the return code is 0, 1, or 2, we have a valid xml file. If we
# get another return code, we have no xml and we can't really say what
# happened -- maybe the TestSuite crashed, maybe valgrind crashed due
# to an illegal instruction. If we get something beside 0-2, we assume
# a crash and fake up an xml entry. After this is all done, we still
# need to indicate a valgrind error somehow, so we fake up an xml entry
# with a VALGR result. Thus, in the case of a working TestSuite that
# fails valgrind, we'll see the PASS entry for the working TestSuite
# followed by a VALGR failing test suite of the same name.
