The contents of `data` are masked with `mask`, as specified in section 5.3 of RFC 6455. Note that this function mutates the `data` argument. This pure-python implementation may be replaced by an optimized version when available. � c s s | ]}t | V qd S )N)rZ )r$ �nr! r! r" rV � s z)_websocket_mask_python.<locals>.<genexpr>Nr r( � )� isinstance� bytearray�AssertionError�len� translate)r[ rB rT rU �c�dr! r! r" �_websocket_mask_python s rf )�_websocket_mask_cython� �_WS_DEFLATE_TRAILINGz�^(?:;\s*(?:(server_no_context_takeover)|(client_no_context_takeover)|(server_max_window_bits(?:=(\d+))?)|(client_max_window_bits(?:=(\d+))?)))*$� _WS_EXT_REzpermessage-deflate([^,]+)?�_WS_EXT_RE_SPLITF)�extstr�isserverrE c C s� | sdS d}d}x�t �| �D ]�}|�d�}|s4d}P t�|�}|r�d}|r�|�d�rxt|�d��}|dksr|dk rxd}q |�d�r�d}P q�|�d �r�t|�d ��}|dks�|dk r�td ��|�d �r�d}P q |s td |�d� ��q W ||fS ) N)r Fr Fr � r\ r) T� zInvalid window sizer( z#Extension for deflate not supported)rk �finditer�grouprj �matchr# rR )rl rm �compress� notakeover�extZdefextrr r! r! r" � ws_ext_parse� s> rv rn )rs rm �server_notakeoverrE c C s^ | dk s| dkrt d��dg}|s,|�d� | dk rF|�dt| � � |rT|�d� d�|�S ) Nr) rn zCCompress wbits must between 9 and 15, zlib does not support wbits=8zpermessage-deflateZclient_max_window_bitszserver_max_window_bits=Zserver_no_context_takeoverz; )� ValueError�appendrM �join)rs rm rw Z enabledextr! r! r" � ws_ext_gen� s r{ c @ s e Zd ZdZdZdZdZdS )� WSParserStater r( r^ r\ N)r r r � READ_HEADER�READ_PAYLOAD_LENGTH�READ_PAYLOAD_MASK� READ_PAYLOADr! r! r! r" r| � s r| c @ s� e Zd Zdee eedd�dd�Zdd�dd�Ze e ee f d �d d �Z e e ee f d �d d �Z e e e eee eee f d�dd�ZdS )r TN)�queue� max_msg_sizers rE c C sp || _ || _d | _t� | _tj| _d | _d| _ d | _ t� | _ d| _ d| _ d | _d| _d| _d | _d | _|| _d S )NF� r )r� � _max_msg_size�_excr` �_partialr| r} �_state�_opcode� _frame_fin� _frame_opcode�_frame_payload�_tail� _has_mask� _frame_mask�_payload_length�_payload_length_flag� _compressed�_decompressobj� _compress)rF r� r� rs r! r! r" rK s" zWebSocketReader.__init__)rE c C s | j �� d S )N)r� �feed_eof)rF r! r! r" r� s zWebSocketReader.feed_eof)rB rE c C sR | j rd|fS y | �|�S tk rL } z|| _ | j�|� dS d }~X Y nX d S )NT)Tr� )r� � _feed_data� Exceptionr� � set_exception)rF rB �excr! r! r" � feed_data s zWebSocketReader.feed_datac C s� �x�| � |�D �]x\}}}}|r8| js8tjtj d�| _|tjk�r"t|�dkr�t|d d� �d }|dk r�|t kr�t t j d|� ���y|dd � � d�}W n0 tk r� } zt t jd�|�W d d }~X Y nX ttj||�} n4|�rt t j d|� d |� d |����nttjdd �} | j�| d� q|tjk�rL| j�ttj|d �t|�� q|tjk�rv| j�ttj|d �t|�� q|tjtjfk�r�| jd k�r�t t j d |����q|�s|tjk�r�|| _| j�|� | j�r�t| j�| jk�r�t t j d � t| j�| j���q| j�r*|tjk�r*t t j d � |���|tjk�rR| jd k �sFt �| j}d | _| j�|� | j�r�t| j�| jk�r�t t j d � t| j�| j���|�r�| j�t � | j� | j| j�} | jj!�r�t| jj!�} t t j d� | j| | j���n t"| j�} | j�#� |tjk�rly*| � d�} | j�ttj| d �t| �� W n2 tk �rh } zt t jd�|�W d d }~X Y nX q| j�ttj| d �t| �� qW dS )N)�wbitsr( r i� zInvalid close code: zutf-8zInvalid UTF-8 text messagezInvalid close frame: � � zUnexpected opcode=z Message size {} exceeds limit {}z<The opcode in non-fin frame is expected to be zero, got {!r}z-Decompressed message size {} exceeds limit {})Fr� )$� parse_framer� �zlib� decompressobj� MAX_WBITSr r2 rb �UNPACK_CLOSE_CODEr' r r r �decode�UnicodeDecodeErrorr r r� r� r0 r1 r. r/ r� r- r� �extendr� r �formatra ri � decompress�unconsumed_tailrW �clear) rF rB �fin�opcode�payload� compressedZ close_codeZ close_messager� �msgZpayload_merged�leftr6 r! r! r" r� & s� zWebSocketReader._feed_data)�bufrE c C s� g }| j r | j | d }| _ d}t|�}�xD| jtjk�rr|| dk�rp|||d � }|d7 }|\}}|d?
