This does not require chroot() or root privileges, it just instructs gdb to search for the files there.

This is suitable for identifying duplicates. For signal crashes this the concatenation of ExecutablePath, Signal number, and StacktraceTop function names, separated by a colon. If StacktraceTop has unknown functions or the report lacks any of those fields, return None. In this case, you can use crash_signature_addresses() to get a less precise duplicate signature based on addresses instead of symbol names. For assertion failures, it is the concatenation of ExecutablePath and assertion message, separated by colons. For Python crashes, this concatenates the ExecutablePath, exception name, and Traceback function names, again separated by a colon. For suspend/resume failures, this concatenates whether it was a suspend or resume failure with the hardware identifier and the BIOS version, if it exists. r� r� )r� r� Nra r� �kernelz^\s*\#\d+\s\[\w+\]\s(\w+)r� r� r� r� rq z0x[0-9a-f]{6,}�ADDRr� z%s:%sz.^(?:([\w:~]+).*|(<signal handler called>)\s*)$r� r� rE z(\w+): r r z)^\s+File "([^"]+).*line (\d+).*\sin (.*)$r� z:%s@%sr� z(%s)�_PythonExceptionQualifierr� r� �suspend�resumer� z:%szdmi.bios.versionr� Fr� zBUG: unable to handlez ^BUG: unable to handle (.*) at z.could not parse expected problem type line: %szIP: z Call Trace:Tr� )rT rj r r� r� r� �subr r r" �islinkr r� r` r� rl r� � _extract_function_and_addressr� )r� �sig�regexr r� r� �linesr �loc_rer� �exc_name� in_trace_bodyr� �parsedr� r r r �crash_signatured s� � �� � �� zReport.crash_signaturec C s> t �d|�}|r |�d�}|sJ d| ��|d dkr |S d S )Nz \[.*\] (.*)$r� z,could not parse expected call trace line: %sr �?)rT rl r� )r� r r% r� r r r r � s z$Report._extract_function_and_addressc C s d| vs d| vs d| vrdS d| d v rdS g }d}| d � � D ]:}|�d�rR|�� d }|�d �s3q t|d �}|d k r=q | �|�}|rN|�|�d d �� n|d7 }t|�dkrZ nq |dkrit|�| dk ridS |dkrst|�dk s}|dkrt|�dk rdS d| d | d d �|�f S )a� Compute heuristic duplicate signature for a signal crash. This should be used if crash_signature() fails, i. e. Stacktrace does not have enough symbols. This approach only uses addresses in the stack trace and does not rely on symbol resolution. As we can't unwind these stack traces, we cannot limit them to the top five frames and thus will end up with several or many different signatures for a particular crash. But these can be computed and synchronously checked with a crash database at the client side, which avoids having to upload and process the full report. So on the server-side crash database we will only have to deal with all the equivalence classes (i. e. same crash producing a number of possible signatures) instead of every single report.
