# # This is a valgrind suppression file that should be used when using valgrind. # # --------------------------------------------------------------------------- # Debian note: # The file Misc/valgrind-python.supp is placed in an modified form into the # directory /usr/lib/valgrind as python.supp. There's no need to to add it # with the --suppressions option. # The unmodified file is found in /usr/share/doc/python3.6/ # # The python3.6-dbg build has been compiled with -DPy_USING_MEMORY_DEBUGGER # so you can safely comment out the suppressions for PyObject_Free and # PyObject_Realloc. # --------------------------------------------------------------------------- # Here's an example of running valgrind: # # cd python/dist/src # valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp \ # ./python -E ./Lib/test/regrtest.py -u gui,network # # You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER # to use the preferred suppressions with 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 { ADDRESS_IN_RANGE/Invalid read of size 4 Memcheck:Addr4 fun:address_in_range } { ADDRESS_IN_RANGE/Invalid read of size 4 Memcheck:Value4 fun:address_in_range } { ADDRESS_IN_RANGE/Invalid read of size 8 (x86_64 aka amd64) Memcheck:Value8 fun:address_in_range } { ADDRESS_IN_RANGE/Conditional jump or move depends on uninitialised value Memcheck:Cond fun:address_in_range } # # Leaks (including possible leaks) # Hmmm, I wonder if this masks some real leaks.
