Preserve a Morsel's coded_value exactly as received from the server.
|
|
This function ensures that cookie encoding is preserved exactly as sent by
|
the server, which is critical for compatibility with old servers that have
|
strict requirements about cookie formats.
|
|
This addresses the issue described in https://github.com/aio-libs/aiohttp/pull/1453
|
where Python's SimpleCookie would re-encode cookies, breaking authentication
|
with certain servers.
|
|
Args:
|
cookie: A Morsel object from SimpleCookie
|
|
Returns:
|
A Morsel object with preserved coded_value

Replace function for _unquote_sub regex substitution.
|
|
Handles escaped characters in cookie values:
|
- Octal sequences are converted to their character representation
|
- Other escaped characters are unescaped by removing the backslash

Note: The original implementation checked for None, but we've removed

that check since all callers already ensure the value is not None.

Parse a Cookie header according to RFC 6265 Section 5.4.
|
|
Cookie headers contain only name-value pairs separated by semicolons.
|
There are no attributes in Cookie headers - even names that match
|
attribute names (like 'path' or 'secure') should be treated as cookies.
|
|
This parser uses the same regex-based approach as parse_set_cookie_headers
|
to properly handle quoted values that may contain semicolons. When the
|
regex fails to match a malformed cookie, it falls back to simple parsing
|
to ensure subsequent cookies are not lost
|

|
Args:
|
header: The Cookie header value to parse
|
|
Returns:
|
List of (name, Morsel) tuples for compatibility with SimpleCookie.update()

Parse cookie headers using a vendored version of SimpleCookie parsing.
|
|
This implementation is based on SimpleCookie.__parse_string to ensure
|
compatibility with how SimpleCookie parses cookies, including handling
|
of malformed cookies with missing semicolons.
|
|
This function is used for both Cookie and Set-Cookie headers in order to be
|
forgiving. Ideally we would have followed RFC 6265 Section 5.2 (for Cookie
|
headers) and RFC 6265 Section 4.2.1 (for Set-Cookie headers), but the
|
real world data makes it impossible since we need to be a bit more forgiving.
|
|
NOTE: This implementation differs from SimpleCookie in handling unmatched quotes.
|
SimpleCookie will stop parsing when it encounters a cookie value with an unmatched
|
quote (e.g., 'cookie="value'), causing subsequent cookies to be silently dropped.
|
This implementation handles unmatched quotes more gracefully to prevent cookie loss.
|
