2 # This is a valgrind suppression file that should be used when using valgrind.
|
|
|
3 #
|
|
|
4 # Here's an example of running valgrind:
|
|
|
5 #
|
|
|
6 # cd python/dist/src
|
|
|
7 # valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp \
|
|
|
8 # ./python -E -tt ./Lib/test/regrtest.py -u bsddb,network
|
|
|
9 #
|
|
|
10 # You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER
|
|
|
11 # to use the preferred suppressions with Py_ADDRESS_IN_RANGE.
|
|
|
12 #
|
|
|
13 # If you do not want to recompile Python, you can uncomment
|
|
|
14 # suppressions for PyObject_Free and PyObject_Realloc. [ => DONE BY SJO ]
|
|
|
15 #
|
|
|
16 # See Misc/README.valgrind for more information.
|
|
|
17
|
|
|
18 # all tool names: Addrcheck,Memcheck,cachegrind,helgrind,massif
