Because imap protocol connections (which are channels) run through a cache,
|
|
it isn't always the case that when you want to run a url, you actually get
|
|
a connection back right away. Often times, the url goes into a queue until
|
|
a connection becomes available.
|
|
|
|
Unfortunately, if we want to be a truly pluggable protocol with necko, necko
|
|
requires the ability to get a channel back right away when it wants to run
|
|
a url. It doesn't let you wait until an imap connection becomes available.
|
|
|
|
So I've created the notion of a "mock channel". This mock channel is what
|
|
gets returned to necko (or other callers) when they ask the imap service
|
|
for a new channel for a url. The mock channel has "mock" implementations
|
|
of nsIChannel. Eventually, when we actually assign the url to a real
|
|
channel, we set the real channel on the mock channel. From that point forward,
|
|
the mock channel forwards channel calls directly to the real channel.
|
|
|
|
In short, this class is how I'm solving the problem where necko wants
|
|
a channel back as soon as they ask for when with the fact that it
|
|
may be a while until the url is loaded into a connection.
