New submission from Mike Watkins <pyt...@mikewatkins.ca>:
HTTPMessage.getallmatchingheaders() stopped working sometime after
Python 3.0 release. In a recent (1 day ago) svn update the
implementation says the method was copied from rfc822.message; the
Python 3.x implementation is broken (iterates through self.keys instead
of header values). I've not looked back to see where the change was
introduced but I do know that it broke post 3.0 release.
But more importantly than the flaw in this method, the functionality is
duplicated elsewhere in Python 3.x.
I propose either deprecating getallmatchingheaders() or if it is to be
kept for compatibility, the fix can be simply replacing the method body
with:
self.get_all(name)
The docstring for get_all (defined in email.message) affirms that its
output is indeed compatible with that which was intended for
getallmatchingheaders().
get_all(self, name, failobj=None) method of client.HTTPMessage instance
Return a list of all the values for the named field.
These will be sorted in the order they appeared in the original
message, and may contain duplicates. Any fields deleted and
re-inserted are always appended to the header list.
If no such fields exist, failobj is returned (defaults to None).
I've tested the use of get_all against one web server (QP) which runs on
both Python 2.x and 3.x.
As a result of the broken getallmatchingheaders() the QP web server now
uses for the same purpose as getallmatchingheaders() instead:
get_all(name) (defined in email.message.Message in Py3k and
getheaders(name) (defined in rfc822.Message).
