142989 - Preview and full screen message window never completes loading message if opened full screen while the same msg is loading in the preview pane

Status: RESOLVED WORKSFORME

(MailNews Core :: Networking: IMAP, defect)

Description

[Ian Batterbee]

If a message is loading in the preview panel, and I double click on the message
um, summary screen (the one line per message bit), it opens a new window with
the message in it (as expected)

There seems to be a problem where the message in the window will only load up to
the point where the message had loaded to in the preview pane when the new
window opened. The preview panel also fails to get any more data as if there is
a contention problem.

This is difficult to reproduce on a fast connection since the message has to be
very large so that you CAN open a new window before the preview pane has loaded
completely, but it is quite easy to do on a dialup connection. I can just do it
with a 50k text message by tripple clicking it on a 128kilobit connection.. so a
 message with 200-300k of text should be a good size to try this with. 

It seems that the second imap connection uses the data that the first has
already loaded, but then sit there and prevent each other from getting any more
data.

An added problem is that the local imap cache doesn't realise that the message
is only partially loaded, and further references to that email will only load it
up to the point it already has. Since it thinks it is a good cached copy, the
only way I could find to reread the message completely was to close mozilla down
and restart it, change folders, load a few more messages, change back, click on
the message ONCE (to get it to load in the preview pane), and then once it was
fully loaded, open it in a new window, which succeeded because the preview pane
had finished with the imap connection.


Steps to reproduce:
1. Find yourself a slow network connection.. The slower the better.
2. Make sure the message preview panel is enabled
3. Load a message, and while it is loading in the preview, double click the
message to cause it to open in a new window.
4. Watch the preview and the full screen messages.. they should never complete
loading the message (but are typically 'stuck' at different positions in the
message)

Reporter, could you please retest with a more newer version of mozilla, either
the latest milestone or a recent nightly?
