Normally you'd pass a connection class to do_open, but it doesn't actually check for a class, and just expects a callable. As long as we behave just as a constructor would have, we should be OK. If it ever changes so that we *must* pass a class, we'll create an UnsafeHTTPSConnection class which just sets check_domain to False in the class definition, and choose which one to pass to do_open. )r� r� r� )r� rc rd r( r, r, r- � _conn_maker� s zHTTPSHandler._conn_makerc C sX z| � | j|�W S tk rR } z$dt|j�kr@td|j ��n� W 5 d }~X Y nX d S )Nzcertificate verify failedz*Unable to verify server certificate for %s)Zdo_openr� r r� �reasonr� r� )r� rY rL r, r, r- � https_open� s �zHTTPSHandler.https_openN)T)r� r� r� r� r� r� r, r, r, r- r� � s r� c @ s e Zd Zdd� ZdS )�HTTPSOnlyHandlerc C s t d| ��d S )NzAUnexpected HTTP request on what should be a secure connection: %s)r )r� rY r, r, r- � http_open� s �zHTTPSOnlyHandler.http_openN)r� r� r� r� r, r, r, r- r� � s r� � �r� � c @ s e Zd Zddd�ZdS )�HTTPr Nc K s& |dkr d }| � | j||f|�� d S r� ��_setupZ_connection_class�r� r� r� rd r, r, r- r� � s z HTTP.__init__)r N�r� r� r� r� r, r, r, r- r� � s r� c @ s e Zd Zddd�ZdS )�HTTPSr Nc K s& |dkr d }| � | j||f|�� d S r� r� r� r, r, r- r� � s zHTTPS.__init__)r Nr� r, r, r, r- r� � s r� c @ s e Zd Zddd�Zdd� ZdS )� Transportr c C s || _ tj�| |� d S ru )r� r r� r� �r� r� � use_datetimer, r, r- r� s zTransport.__init__c C s` | � |�\}}}tdkr(t|| jd�}n4| jr<|| jd krR|| _|t�|�f| _| jd }|S )Nr� )r� r r )� get_host_info� _ver_infor� r� � _connection�_extra_headersr ZHTTPConnection)r� r� �h�ehZx509r( r, r, r- �make_connection s zTransport.make_connectionN)r �r� r� r� r� r� r, r, r, r- r� s r� c @ s e Zd Zddd�Zdd� ZdS )� SafeTransportr c C s || _ tj�| |� d S ru )r� r r� r� r� r, r, r- r� s zSafeTransport.__init__c C sx | � |�\}}}|si }| j|d< tdkr:t|d f|�}n:| jrN|| jd krj|| _|tj|d f|�f| _| jd }|S )Nr� r� r r )r� r� r� r� r� r� r r� )r� r� r� r� rd r( r, r, r- r� s � z SafeTransport.make_connectionN)r r� r, r, r, r- r� s r� c @ s e Zd Zdd� ZdS )� ServerProxyc K st |� dd � | _}|d k r^t|�\}}|�dd�}|dkr@t}nt}|||d� |d< }|| _tjj | |f|� d S )Nr� r� r Zhttps)r� � transport) rh r� r rI r� r� r� r r� r� ) r� rZ rd r� rW r] r� Ztclsr\ r, r, r- r� , s zServerProxy.__init__Nr� r, r, r, r- r� + s r� c K s6 t jd dk r|d7 }nd|d< d|d< t| |f|�S )Nr r� �br �newliner� r� )rq r� r� )rX r� rd r, r, r- � _csv_open@ s r� c @ s4 e Zd Zed�ed�ed�d�Zdd� Zdd� Zd S ) �CSVBaserC �"r� )Z delimiterZ quotecharZlineterminatorc C s | S ru r, r� r, r, r- � __enter__R s zCSVBase.__enter__c G s | j �� d S ru )r� r� )r� r& r, r, r- �__exit__U s zCSVBase.__exit__N)r� r� r� r� �defaultsr� r� r, r, r, r- r� K s �r� c @ s( e Zd Zdd� Zdd� Zdd� ZeZdS )� CSVReaderc K s\ d|kr4|d }t jd dkr,t�d�|�}|| _nt|d d�| _tj| jf| j�| _d S )Nr� r r� r� rb rG ) rq r� r� r� r� r� �csvrK r� )r� rd r� r, r, r- r� Z s zCSVReader.__init__c C s | S ru r, r� r, r, r- �__iter__e s zCSVReader.__iter__c C sF t | j�}tjd dk rBt|�D ] \}}t|t�s |�d�||< q |S �Nr r� r� )�nextrK rq r� r7 rx r r� )r� r( r[ r� r, r, r- r� h s zCSVReader.nextN)r� r� r� r� r� r� �__next__r, r, r, r- r� Y s r� c @ s e Zd Zdd� Zdd� ZdS )� CSVWriterc K s$ t |d�| _tj| jf| j�| _d S )Nr� )r� r� r� �writerr� )r� rX rd r, r, r- r� s s zCSVWriter.__init__c C sN t jd dk r>g }|D ]"}t|t�r.|�d�}|�|� q|}| j�|� d S r� )rq r� rx r r� r" r� �writerow)r� �rowrG r� r, r, r- r� w s zCSVWriter.writerowN)r� r� r� r� r� r, r, r, r- r� r s r� c sH e Zd Zeej�Zded< d � fdd� Zdd� Zdd � Zd d � Z � Z S ) � Configurator� inc_convertZincNc s" t t| ��|� |pt�� | _d S ru )�superr r� ra r� rj )r� �configrj �� __class__r, r- r� � s zConfigurator.__init__c s� ��fdd��� � d�}t|�s*��|�}� � dd �}� � dd�}|r\t�fdd�|D ��}� �fd d�� D �}t|�}|||�}|r�|�� D ]\}} t||�| �� q�|S ) Nc sv t | ttf�r*t| �� fdd�| D ��}nHt | t�rhd| krH��| �}qri }| D ]}� | | �||< qPn ��| �}|S )Nc s g | ] }� |��qS r, r, )rN r[ ��convertr, r- rO � s zBConfigurator.configure_custom.<locals>.convert.<locals>.<listcomp>�())rx r r{ �type�dict�configure_customr )�or( r� )r r� r, r- r � s z.Configurator.configure_custom.<locals>.convertr r z[]r, c s g | ] }� |��qS r, r, )rN r r r, r- rO � s z1Configurator.configure_custom.<locals>.<listcomp>c s$ g | ] }t |�r|�� | �f�qS r, )r )rN r� )r r r, r- rO � s )rh r r r{ r r� �setattr) r� r r~ Zpropsrc r� rd r( rB rI r, )r r r� r- r � s z Configurator.configure_customc C s4 | j | }t|t�r0d|kr0| �|� | j |< }|S )Nr )r rx r r )r� r� r( r, r, r- � __getitem__� s zConfigurator.__getitem__c C sF t j�|�s t j�| j|�}tj|ddd��}t�|�}W 5 Q R X |S )z*Default converter for the inc:// protocol.rG r� r� ) ra rb �isabsr$ rj r� r� r� r� )r� r� r� r( r, r, r- r � s zConfigurator.inc_convert)N) r� r� r� r r Zvalue_convertersr� r r r � __classcell__r, r, r r- r � s r c @ s* e Zd ZdZd dd�Zdd� Zdd � ZdS ) �SubprocessMixinzC Mixin for running subprocesses and capturing their output FNc C s || _ || _d S ru )�verbose�progress)r� r r r, r, r- r� � s zSubprocessMixin.__init__c C sj | j }| j}|�� }|sq^|dk r.|||� q |s@tj�d� ntj�|�d�� tj�� q |�� dS )z� Read lines from a subprocess' output stream and either pass to a progress callable (if specified) or write progress information to sys.stderr.
