Credit to Mark Williams for these. .. _mbox: https://en.wikipedia.org/wiki/Mbox éNi@c@s"eZdZdZd dd„Zdd„ZdS) Úmbox_readonlydira&A subclass of :class:`mailbox.mbox` suitable for use with mboxs insides a read-only mail directory, e.g., ``/var/mail``. Otherwise the API is exactly the same as the built-in mbox. Deletes messages via truncation, in the manner of `Heirloom mailx`_. Args: path (str): Path to the mbox file. factory (type): Message type (defaults to :class:`rfc822.Message`) create (bool): Create mailbox if it does not exist. (defaults to ``True``) maxmem (int): Specifies, in bytes, the largest sized mailbox to attempt to copy into memory. Larger mailboxes will be copied incrementally which is more hazardous. (defaults to 4MB) .. note:: Because this truncates and rewrites parts of the mbox file, this class can corrupt your mailbox. Only use this if you know the built-in :class:`mailbox.mbox` does not work for your use case. .. _Heirloom mailx: http://heirloom.sourceforge.net/mailx.html NTécCstj ||||¡||_dS)N)ÚmailboxÚmboxÚ__init__Úmaxmem)ÚselfÚpathÚfactoryÚcreater©r úZ/var/www/html/stable-diffusion-webui/venv/lib/python3.9/site-packages/boltons/mboxutils.pyrHszmbox_readonlydir.__init__c CsÔ|js"|jrt |j¡d|_dS|jdus0J‚|j dd¡|j ¡}||jkrft  d|j|f¡‚|j d¡t   ¡}i}|  |¡t |j ¡ƒD]|}|j|\}}|j |¡| |¡| ¡}|j td||j ¡ƒ¡}|dkrðqü| |¡qÊ|| ¡f||<| |¡qš| ¡|_|j d¡| d¡|j|jkrX|j | ¡¡n$| d¡}|slq||j |¡qX|j ¡Wdƒn1sœ0Y||_d|_d|_|jrÐtj|jdddS) zñWrite any pending changes to disk.
