Subject: [PATCH 1/1] perf python: Fix binding linkage due to rename and move of evsel__increase_rlimit()
Date: Fri, 27 Oct 2023 10:33:30 -0300	[thread overview]
Message-ID: <ZTu8Kgb2KqifMBZ3@kernel.org> (raw)
In-Reply-To: <CAM9d7cjhSSV+18ZCHLdTFpMM+MmpoDkYSGjUa5JKZp02Kx9XRw@mail.gmail.com>

The changes in ("perf evsel: Rename evsel__increase_rlimit to
rlimit__increase_nofile") ended up breaking the python binding that now
references the rlimit__increase_nofile function, add the util/rlimit.o
to the tools/perf/util/python-ext-sources to cure that.

This was detected by the 'perf test python' regression test:

  $ perf test python
   14: 'import perf' in python        : FAILED!

  $ perf test -v python
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
   14: 'import perf' in python                                         :
  --- start ---
  test child forked, pid 2912462
  python usage test: "echo "import sys ; sys.path.insert(0, '/tmp/build/perf-tools-next/python'); import perf" | '/usr/bin/python3' "
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf-tools-next/python/perf.cpython-311-x86_64-linux-gnu.so: undefined symbol: rlimit__increase_nofile
  test child finished with -1
  ---- end ----
  'import perf' in python: FAILED!
