Sure, I can put different things there, but that would also be a change in
semantics.
The backwards compat class, HTTP, preserves the API completely -- even down
to how it reacts in error situations. (although, it *can* raise errors that
it didn't before, when you use methods in the wrong order)
I'd like to make a change in the semantics for this particular error
condition. Where a client used to be able to do:
errcode, errmsg, hdrs = h.getreply()
if errcode == -1:
file = h.getfile()
print 'ERROR: some kind of error occurred'
print ' partial read:', `errmsg`
print ' next 100 bytes:', `file.read(100)`
I'd like to eliminate that "next 100 bytes" ability, and just close the
socket when a protocol error occurs. Before making a change in behavior for
this (central) class, I'd like to get some feedback. Some voting?
Cheers,
