S )wa HTTP cookie handling for web clients.
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.

distributed with the Python standard library, but are available from

a Returns time in seconds since epoch of time represented by a string.
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.

dd|\}} |}qW |r | | q W |S )am Parse header values into a list of lists containing key,value pairs.
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*
separators = "(" | ")" | "<" | ">" | "@"
| "," | ";" | ":" | "\" | <">
| "/" | "[" | "]" | "?" | "="
| "{" | "}" | SP | HT
quoted-string = ( <"> *(qdtext | quoted-pair ) <"> )
qdtext = >
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"')]]

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.

A and B may be host domain names or IP addresses.
RFC 2965, section 1:
Host names can be specified either as an IP address or a HDN string.
Sometimes we compare one host name with another. (Such comparisons SHALL
be case-insensitive.) Host A's name domain-matches host B's if
* their host name strings string-compare equal; or
* A is a HDN string and has the form NB, where N is a non-empty
name string, B has the form .B', and B' is a HDN string. (So,
x.y.com domain-matches .Y.com but not Y.com.)
Note that domain-match is not a commutative operation: a.b.c.com
domain-matches .c.com, but not the reverse.

dS )r a HTTP Cookie.
This class represents both Netscape and RFC 2965 cookies.
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.

attrs_set is the list of lists of key,value pairs extracted from
the Set-Cookie or Set-Cookie2 headers.
Tuples are name, value, standard, rest, where name and value are the
cookie name and value, standard is a dictionary containing the standard
cookie-attributes (discard, secure, version, expires or max-age,
domain, path and port) and rest is a dictionary containing the rest of
the cookie-attributes.

"Set-Cookie3" is the format used by the libwww-perl library, not known
to be compatible with any browser, but which is easy to read and
doesn't lose information about RFC 2965 cookies.

WARNING: you may want to backup your browser's cookies file if you use
this class to save cookies. 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).
