# Valgrind suppressions for known false positives in the nvme-cli test suite.
#
# Used automatically by: meson test --setup valgrind
#
# Three categories of suppressions are defined here:
#
#   1. Bash interpreter internals — the valgrind exe_wrapper invokes bash
#      directly for shell-script-based tests. Leaks from bash itself are
#      not our code.
#
#   2. CPython interpreter internals — Python test scripts import our libnvme
#      Python bindings. CPython's import machinery, marshal, and unicode
#      internals generate reports that are not leaks in our code.
#      Two obj: patterns are needed: one for distros where Python is a static
#      binary (/usr/bin/python3.*) and one for distros where it is dynamically
#      linked against a shared library (*libpython3*).
#
#   3. SWIG module teardown — SWIG allocates a varlink object during module
#      initialisation that CPython never releases during interpreter shutdown.
#      This is a known SWIG limitation, not a leak in libnvme.
