# I recommend to use valgrind like this:
# G_DEBUG=gc-friendly G_SLICE=always-malloc valgrind --leak-check=full --log-file=out ./profanity
#
# This file is a combination of our own rules and
# * the glib2 suppressions file that usually can be found at /usr/share/glib-2.0/valgrind/glib.supp
# * python suppressions file from http://svn.python.org/projects/python/trunk/Misc/valgrind-python.supp

## glib 2.60.4 suppressions file:
# GLib Valgrind suppressions file
#
# This provides a list of suppressions for all of GLib (including GIO), for all
# Valgrind tools (memcheck, drd, helgrind, etc.) for the false positives and
# deliberate one-time leaks which GLib causes to be reported when running under
# Valgrind.
#
# When running an application which links to GLib under Valgrind, you can pass
# this suppression file to Valgrind using --suppressions=/path/to/glib-2.0.supp.
#
# http://valgrind.org/docs/manual/manual-core.html#manual-core.suppress
#
# Note that there is currently no way for Valgrind to load this automatically
# (https://bugs.kde.org/show_bug.cgi?id=160905), so the best GLib can currently
# do is to install this file as part of its development package.
#
# This file should be updated if GLib introduces a new deliberate one-time leak,
# or another false race positive in Valgrind: please file bugs at:
#
# https://gitlab.gnome.org/GNOME/glib/issues/new

## python suppressions file:
#
# This is a valgrind suppression file that should be used when using valgrind.
#
# Here's an example of running valgrind:
#
# cd python/dist/src
# valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp \
# ./python -E -tt ./Lib/test/regrtest.py -u bsddb,network
#
# You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER
# to use the preferred suppressions with Py_ADDRESS_IN_RANGE.
#
# If you do not want to recompile Python, you can uncomment
# suppressions for PyObject_Free and PyObject_Realloc.
#
# See Misc/README.valgrind for more information.
# all tool names: Addrcheck,Memcheck,cachegrind,helgrind,massif
