124036 - Saving to a slow device blocks progress dialog from displaying

Status: NEW

(Firefox :: File Handling, defect)

Description

[Bill Law]

This is another error encountered while working on a new set of progress-dialog
code.

If I save to a diskette, then the progress dialog never updates.  All I see is
the title bar.  This is reproducible 99% of the time in my debug builds.  My
theory is that if the time it takes to do the Write() exceeds the time between
OnDataAvailable calls, then things get horked.

I'm assigning this to myself.  I want to re-investigate this after my new
progress  dialog code lands.

This is reproducible with the current code, I believe.

It seems like it might behave differently (worse) for ftp.

A possible fix would be to make the network callback/notification events have 
lower priority.  That way, the drawing events would have a chance to get 
processed.

That isn't likely to happen soon, and it wouldn't be me that fixed it, probably.

Reassigning to networking component owner to see if an owner can be found for 
this.

+helpwanted: developer requests can go directly to eng.

btw, is this an all/all bug?
