If binary is False, binary data is not loaded; the dictionary key is created, but its value will be an empty string. If it is True, it is transparently uncompressed and available as dictionary byte array values. If binary is 'compressed', the compressed value is retained, and the dictionary value will be a CompressedValue object. This is useful if the compressed value is still useful (to avoid recompression if the file needs to be written back). file needs to be opened in binary mode. If key_filter is given, only those keys will be loaded. Files are in RFC822 format, but with case sensitive keys.

If only_new is True, only keys which have been added since the last load() are written (i. e. those returned by new_keys()). If a value is a string, it is written directly. Otherwise it must be a tuple of the form (file, encode=True, limit=None, fail_on_empty=False). The first argument can be a file name or a file-like object, which will be read and its content will become the value of this key. 'encode' specifies whether the contents will be gzip compressed and base64-encoded (this defaults to True). If limit is set to a positive integer, the file is not attached if it's larger than the given limit, and the entire key will be removed. If fail_on_empty is True, reading zero bytes will cause an IOError. file needs to be opened in binary mode.

It needs to be opened in binary mode. If a value is a string or a CompressedValue, it is written directly. Otherwise it must be a tuple containing the source file and an optional boolean value (in that order); the first argument can be a file name or a file-like object, which will be read and its content will become the value of this key. The file will be gzip compressed, unless the key already ends in .gz. attach_treshold specifies the maximum number of lines for a value to be included into the first inline text part. All bigger values (as well as all non-ASCII ones) will become an attachment, as well as text values bigger than 1 kB. Extra MIME preamble headers can be specified, too, as a dictionary. skip_keys is a set/list specifying keys which are filtered out and not written to the destination file. priority_fields is a set/list specifying the order in which keys should appear in the destination file. � r6 r rD Nr� r! r� z.gzr r Tr$ � applicationzx-gzipzContent-Disposition� attachment)�filenamer� r� i� z: � z: z )�_charsetz.txt�inlinerC )(rI �sortedr: r[ rS r� ri r r r� rl rQ r! r r r r r� r r� r � add_header� set_payloadr r� r* r= r� rX rj r/ �rstriprY r� r r rs �attach� as_stringrZ )r r% �attach_treshold� extra_headers� skip_keys�priority_fieldsr[ �text� attachments�counter�priority_fieldr� r� � attach_valuer� �io�gfr' �attr� �lines�msg�ar r r � write_mime� s� � � zProblemReport.write_mimec C s� t |d�sJ �|�dd��dd��dd��� s td| ��t|t�sXt |d�sXt|t�rRt|�dksDt|�dkrRt|�d krR|d d v rRt |d d�sXt |d d �sXtd | ��| j � ||�S )N�isalnum�.r� �-�_z[key '%s' contains invalid characters (only numbers, letters, '.', '_', and '-' are allowed)rD r� r� )TFr r! zGvalue for key %s must be a string, CompressedValue, or a file reference) r� r� r� rr ri r �tupler* � TypeErrorr: � __setitem__)r r� r� r r r r� ~ s �0 � � zProblemReport.__setitem__c C s t | j�� �| j S )z�Return newly added keys.
