[ Impact ] * This error report is the equivalent for this bug in Noble: https://errors.ubuntu.com/problem/472e8b056e334653c0eab820f0d83e22949fcbee * AssertionError: cannot parse ProcMaps line: Error: [Errno 3] No such process: 'maps' ``` Traceback (most recent call last): File "/usr/share/apport/whoopsie-upload-all", line 246, in <module> main() File "/usr/share/apport/whoopsie-upload-all", line 228, in main stamps = collect_info() ^^^^^^^^^^^^^^ File "/usr/share/apport/whoopsie-upload-all", line 162, in collect_info res = process_report(r) ^^^^^^^^^^^^^^^^^ File "/usr/share/apport/whoopsie-upload-all", line 112, in process_report r.add_gdb_info() File "/usr/lib/python3/dist-packages/apport/report.py", line 1022, in add_gdb_info addr_signature = self.crash_signature_addresses() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/apport/report.py", line 1761, in crash_signature_addresses offset = self._address_to_offset(addr) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/apport/report.py", line 1969, in _address_to_offset self._build_proc_maps_cache() File "/usr/lib/python3/dist-packages/apport/report.py", line 2005, in _build_proc_maps_cache assert m, "cannot parse ProcMaps line: " + line ^ AssertionError: cannot parse ProcMaps line: Error: [Errno 3] No such process: 'maps' ``` * The upload fixes the bug as https://github.com/canonical/apport/pull/540 adds a fix to catch all error cases as the function _read_maps reads /proc/pid/maps but will return a string starting with Error: in case of an OSError. [ Test Plan ] * This crash can be reproduced by having apport try to process a crash - dump for a process that has already exited. + dump for a process that has already exited: + + ``` + FAKE_PID_DIR=$(mktemp -d) + FAKE_PID=99999 + + mkdir -p "$FAKE_PID_DIR/fd" + + mount --bind '$FAKE_PID_DIR' /proc/$FAKE_PID 2>/dev/null || true + apport -p $FAKE_PID 2>&1 || true + ``` * https://github.com/canonical/apport/pull/540 also introduced a unit test for this. [ Where problems could occur ] * We are adding an error case to the error handler so a syntax error might lead to incorrect error message or failure to build. * Since apport is primarily for crash reports, user experience is unlikely to be affected much.
