This module has (now fairly distant) origins in Gisle Aas' Perl module HTTP::Cookies, from the libwww-perl library. Docstrings, comments and debug strings in this code refer to the attributes of the HTTP cookie system as cookie-attributes, to distinguish them clearly from Python attributes.

Return value is an integer. None is returned if the format of str is unrecognized, the time is outside the representable range, or the timezone string is not recognized. If the string contains no timezone, UTC is assumed. The timezone in the string may be numerical (like "-0800" or "+0100") or a string timezone (like "UTC", "GMT", "BST" or "EST"). Currently, only the timezone strings equivalent to UTC (zero offset) are known to the function. The function loosely parses the following formats: Wed, 09 Feb 1994 22:23:32 GMT -- HTTP format Tuesday, 08-Feb-94 14:15:29 GMT -- old rfc850 HTTP format Tuesday, 08-Feb-1994 14:15:29 GMT -- broken rfc850 HTTP format 09 Feb 1994 22:23:32 GMT -- HTTP format (no weekday) 08-Feb-94 14:15:29 GMT -- rfc850 format (no weekday) 08-Feb-1994 14:15:29 GMT -- broken rfc850 format (no weekday) The parser ignores leading and trailing whitespace. The time may be absent. If the year is given with only 2 digits, the function will select the century that makes the year closest to the current date. r r r r< N )STRICT_DATE_RErA groupsrJ rK rL rB floatr- lstrip WEEKDAY_REsubLOOSE_HTTP_DATE_RErV ) textrF grR r' r1 rS rT r+ r, rD r r r http2time s rd a ^ (\d{4}) # year [-\/]?

The function knows how to deal with ",", ";" and "=" as well as quoted values after "=". A list of space separated tokens are parsed as if they were separated by ";". If the header_values passed as argument contains multiple values, then they are treated as if they were a single value separated by comma ",". This means that this function is useful for parsing header fields that follow this syntax (BNF as from the HTTP/1.1 specification, but we relax the requirement for tokens). headers = #header header = (token | parameter) *( [";"] (token | parameter)) token = 1*<any CHAR except CTLs or separators> separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "\" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT quoted-string = ( <"> *(qdtext | quoted-pair ) <"> ) qdtext = <any TEXT except <">> quoted-pair = "\" CHAR parameter = attribute "=" value attribute = token value = token | quoted-string Each header is represented by a list of key/value pairs. The value for a simple token (not part of a parameter) is None. Syntactically incorrect headers will not necessarily be parsed as you would want. This is easier to describe with some examples: >>> split_header_words(['foo="bar"; port="80,81"; discard, bar=baz']) [[('foo', 'bar'), ('port', '80,81'), ('discard', None)], [('bar', 'baz')]] >>> split_header_words(['text/html; charset="iso-8859-1"']) [[('text/html', None), ('charset', 'iso-8859-1')]] >>> split_header_words([r'Basic realm="\"foo\bar\""']) [[('Basic', None), ('realm', '"foobar"')]] r z\1N,z^[=\s;]*rY )HEADER_TOKEN_RErA rm rC HEADER_QUOTED_VALUE_REHEADER_ESCAPE_REr` HEADER_VALUE_RErstripappendr^ startswithresubn) Z header_valuesresultrb Z orig_textpairsrF namevalueZnon_junkZ nr_junk_charsr r r split_header_wordsU s: . r| ([\"\\])c C s| g }| D ]h}g }|D ]F\}}|durPt d|sDtd|}d| }d||f }|| q|r|d| qd|S )a Do the inverse (almost) of the conversion done by split_header_words.

The old Netscape cookie format for Set-Cookie can for instance contain an unquoted "," in the expires field, so we have to use this ad-hoc parser instead of split_header_words. XXX This may not make the best possible effort to parse all the crap that Netscape Cookie headers contain. Ronald Tschalar's HTTPClient parser is probably better, so could do worse than following that if this ever gives any trouble. Currently, this is also used for parsing RFC 2109 cookies. )expiresdomainpathsecureversionportmax-ageF;=r Nr Tr )r 0) enumeratesplitstrip partitionrL r rd rt ) Z ns_headersZ known_attrsrx Z ns_headerry version_setiiZparamkeysepvallcr r r parse_ns_headers s> r z\.\d+$c C s: t | rdS | dkrdS | d dks2| d dkr6dS dS )z*Return True if text is a host domain name.FrY r .r TIPV4_RErA r r r r is_HDN s r c C sl | } | }| |kr dS t| s(dS | |}|dksB|dkrFdS |dsTdS t|dd shdS dS )a Return True if domain A domain-matches domain B, according to RFC 2965.

This is deliberately a very simple class. It just holds attributes. It's possible to construct Cookie instances that don't comply with the cookie standards. CookieJar.make_cookies is the factory function for Cookie objects -- it deals with cookie parsing, supplying defaults, and normalising to the representation used in this class. CookiePolicy is responsible for checking them to see whether they should be accepted from and returned to the server. Note that the port may be present in the headers, but unspecified ("Port" rather than"Port=80", for example); if this is the case, port is None.

I *think* it works, but there have been bugs in the past! This class differs from CookieJar only in the format it uses to save and load cookies to and from a file. This class uses the Mozilla/Netscape `cookies.txt' format. lynx uses this file format, too. Don't expect cookies saved while the browser is running to be noticed by the browser (in fact, Mozilla on unix will overwrite your saved cookies if you change them on disk while it's running; on Windows, you probably can't save at all while the browser is running). Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to Netscape cookies on saving. In particular, the cookie version and port number information is lost, together with information about whether or not Path, Port and Discard were specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the domain as set in the HTTP header started with a dot (yes, I'm aware some domains in Netscape files start with a dot and some don't -- trust me, you really don't want to know any more about this). Note that though Mozilla and Netscape use the same format, they use slightly different headers. The class saves cookies using the Netscape header by default (Mozilla can cope with that). z #( Netscape)?
