If the crash is new, it will be added to the duplicate database and the function returns None. If the crash is already known, the function returns a pair (crash_id, fixed_version), where fixed_version might be None if the crash is not fixed in the latest version yet. Depending on whether the version in report is smaller than/equal to the fixed version or larger, this calls close_duplicate() or mark_regression(). If the report does not have a valid crash signature, this function does nothing and just returns None. By default, the report gets download()ed, but for performance reasons it can be explicitly passed to this function if it is already available. �-init_duplicate_db() needs to be called before�DuplicateSignature�Package� Nr ���z0SELECT count(*) FROM crashes WHERE crash_id == ?z7INSERT INTO crashes VALUES (?, ?, ?, CURRENT_TIMESTAMP))r �download�_mark_dup_checked�crash_signature�_duplicate_search_signature�_duplicate_db_sync_status�split�KeyError� IndexError�apport� packaging�compare_versions�mark_regression�crash_signature_addresses�#_duplicate_search_address_signature�close_duplicate�_duplicate_db_merge_id�#_duplicate_db_add_address_signaturer+ r, r0 r r- )r �idr �sig�existing�ex_id�_�report_package_version� master_id� master_ver�ex_ver�addr_sig� addr_matchr6 �count_idr r r �check_duplicate� sr � � z CrashDatabase.check_duplicatec C s* | j �d�sdS dD ]�}|dkr d|v r|d }n |�� }n|�� }|s%q | �|�}|s/ dS tj�| j d |t|��}zt |�}|� � � d�}|� � d|v rRW q W n t tfy^ Y q w |�� D ].}z|�dd�\} } t| �} W n ty| Y qcw | |kr�| �|| �} | s�d } | S qcq dS ) a� Check if the crash db already knows about the crash signature. Check if the report has a DuplicateSignature, crash_signature(), or StacktraceAddressSignature, and ask the database whether the problem is already known.

Create a number of text files in the given directory which Apport clients can use to determine whether a problem is already reported to the database, through the known() method. This directory is suitable for publishing to the web. The database is indexed by the first two fields of the duplicate or crash signature, to avoid having to download the entire database every time.

This should happen noninteractively. If the implementation supports it, and a function progress_callback is passed, that is called repeatedly with two arguments: the number of bytes already sent, and the total number of bytes to send. This can be used to provide a proper upload progress indication on frontends. Implementations ought to "assert self.accepts(report)". The UI logic already prevents uploading a report to a database which does not accept it, but for third-party users of the API this should still be checked.
