Platforms: Unix, MacOS, Windows

Module author: René Köcher <shirk@bitspin.org>

class synfu.fucore.FUCore(conf)¶

FUCore contains the generic code and utility methods shared by both synfu.postfilter.PostFilter and synfu.reactor.Reactor.

All of this methods are private and should only be called by subclasses.

_log(message, *args, **kwargs)¶

Log a message using syslog as well as sys.stdout.

Parameters:	message – The pre-formatted log message. rec – Optional recursion level used to indent messages. verbosity – Minimal verbosity required to display this message.
Returns:	None

_is_cancel(message)¶

Check if the passed message is a CANCEL message.

This will try to match FUCore.CANCEL_EXP against all Control: headers contained in message.

Parameters:	message – A email.message object.
Returns:	True or False

_find_list_tag(message, rec=0, plain=False)¶

Filter message for a valid list tag.

This method will scan the passed in messages headers looking for a hint to the used list-tag.

The following headers will be checked (in order):

• X-SynFU-Tags (explicit List-Tags supplied by synfu-news2mail)
• [X-]List-Post
• [X-]List-Id
• [X-]AF-Envelope-to

If any of these is found it will be converted into a regular expression which can be used to remove the List-Tag from arbitrary headers.

Parameters:	message – A email.message object. rec – Optional recursion level used to indent messages. plain – If True return the plain List-Tag (no regexp)
Returns:	Either a re.SRE_PATTERN or a string

_filter_headers(list_tag, headers, outlook_hacks=False, fix_dateline=False, rec=0)¶

Filter a list of headers according to the global settings.

This method will filter the passed in header list by matching a series of expressions and filters to it:

• if list_tag is specified and matched in the Subject: header it will be removed
• if outlook_hacks is enabled then outlook-style AW:/FWD:/... subjects will be converted to RFC compliant versions
• if fix_dateline is enabled Date-headers with broken timezone (like those sent by Incredymail) will get their timezone fixed.
• all tags matching FUCore.HEADER_IGN will be discarded with the exception of X-No-Archive.

Parameters:	list_tag – A re.SRE_PATTERN as returned by FUCore._find_list_tag(). headers – A list of (key, value) headers outlook_hacks – If True convert AW:/FWD:/... subjects to RFC versions. rec – Optional recursion level used to indent messages.
Returns:	The filtered header list.
