Scaleway user/vendor data API returns HTTP/404 if user/vendor data is not set. This function calls `url_helper.readurl` but instead of considering HTTP/404 as an error that requires a retry, it considers it as empty user/vendor data. Also, be aware the user data/vendor API requires the source port to be below 1024 to ensure the client is root (since non-root users can't bind ports below 1024). If requests raises ConnectionError (EADDRINUSE), the caller should retry to call this function on an other port.

Handle the retrying logic in case the source port is used. Scaleway metadata service requires the source port of the client to be a privileged port (<1024). This is done to ensure that only a privileged user on the system can access the metadata service. r r z*Trying to get %s data (bind on port %d)...z0.0.0.0r �[���N)�protoz0::zhttp://)r )r5 r< z%s-data downloadedz%Error while trying to get %s data: %s� )�range�max�LOG�debugr/ ZSessionr �netlocr$ Z getaddrinfoZ IPPROTO_TCPZAF_INET6� ValueErrorZmountr r> r r: �warning�time�sleep) Zapi_typer; r6 r5 �portr< Z localhostZ url_address�addressZ addr_protor4 r2 �last_excr r r �query_data_apid sL � ��� �� $rO c s� e Zd ZdZejejejej hiZ � fdd�Z e dd�� fdd� Z dd � Zd d � Zed d � �Zdd� Zedd� �Zedd� �Zdd� Zdd� Zd dd�Zedd � �Zed d � �Z� ZS ) �DataSourceScaleway�Scalewayc s� t t| ��|||� t�t�|ddgi �g�| _t| j�dt ��| _ t| j�dt ��| _ t| j�dt ��| _tj| _t| _d | _d | _d | _d | _d| _d| j�� v r�| j| jd 7 _d S )NZ datasourcerQ r6 r5 �max_waitT� metadata_urls)r rP r r Z mergemanydictZget_cfg_by_pathZds_cfg�int�get�DEF_MD_RETRIESr6 �DEF_MD_TIMEOUTr5 �DEF_MD_MAX_WAITrR r �UNSET�_network_config� DS_BASE_URLSrS � metadata_url� userdata_url�vendordata_url�ephemeral_fixed_address�has_ipv4�keys)r Zsys_cfg�distro�pathsr r r r � s" ��zDataSourceScaleway.__init__N)�ci_pkl_version�returnc sF t � �|� d dttd d d�}|D ] }t| |�s"t| ||| � q"d S )NT)r_ r` rR rS r] r^ )r � _unpicklerX r[ �hasattr�setattr)r rd Z attr_defaults�attrr r r rf � s � z DataSourceScaleway._unpicklec C s| t �� }tj|| j| jdd�\}}|rZt�d|� |� d�| _|� d�| _ |� d�| _ dS t�d|t t �� | �� t �dS ) zO Define metadata_url based upon api-metadata URL availability.
