81951 - Keyboard+scrollbars don't respond during "Transferring data from ..." (while a new page is loading)

Status: RESOLVED DUPLICATE of bug 76495

(Core :: XUL, defect)

Description

[doctor__j]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9+) Gecko/20010518
BuildID:    2001051804

Reproducible: Always
Steps to Reproduce:
1. Load any URL (preferrably some sites which are slow to connect)
2. When you see "Transferring data from ..." in the status bar, enter some
keyboard shortcuts, like Ctrl-N, Alt-F, etc. or even just press Alt key to raise
up the File menu tab.
3. Mozilla doesn't accept your keypress.  Only mouse can do the control at this
moment until the browser starts to render the page.

Expected Results:  Keypress is processed any time during browsing.

i cannot repro this either [winnt, linux, mac] using 2001.05.31.0x comm bits.
[eg, http://www.voodooextreme.com]

is this [still] a problem for anyone else? if so, pls do reopen.

Still happens using Win32 build 2001062606.

Timing is important in reproducing this bug.

Keyboard is not responding when the page content is just being downloaded,
before the content being rendered out on the screen.  Try again a few times if
you can't catch the bug.
I am on 56k connection.  I think this helps to extend the timeframe in which I
can reproduce this bug.

This is a major problem for keyboard users.  Mouse users can escape most web
site "lock-ins" (intentional or unintentional) by pressing the back button twice
quickly, but pressing alt+left twice quickly doesn't have the same effect
because of this bug.  See dup bug 87963.

akkana, kathy, are either of you able to repro this on linux or mac
[respectively]? looks like a slow connection helps here --also see jesse's
testcase in 87963... i'll check this out in a bit...

Well, I never get the "transferring data from ..." message; my status bar stays
on "Connecting to..." until the whole page is loaded.  But it's true that I
can't seem to stop the load by hitting a keyboard shortcut like alt-backarrow,
while mousing twice on the backarrow button is marginally more successful.

This might be related to focus; there's no telling what the focus manager might
be doing with the focus while a page is loading, and perhaps the focus is
somewhere where no key bindings work.  All of the sample pages in this bug and
87963 involve lots of popups (and juggling cookie dialogs when I go there the
first time; after the first time, they are no longer slow to load because
they're coming from cache) so the focus is changing all over the place and it's
not surprising that it's not back in the main window.

It would be useful to have a page which was reliably slow to load regardless of
connection speed (a CGI with a delay loop?) yet had no popups or other focus
changes.

I got it!  I got it!

Repro steps...

1. Go to the URL above
(http://tinderbox.mozilla.org/bonsai/cvsquery.cgi?module=MozillaTinderboxAll&date=explicit&mindate=993752700).
2. Observe the following messages in status bar:
   a) Resolving host tinderbox.mozilla.org 
   b) Connecting to tinderbox.mozilla.org
   c) Transferring data from tinderbox.mozilla.org
   d) Connecting to bonsai.mozilla.org
   e) Transferring data from bonsai.mozilla.org
3. When message (e) is shown in status bar, try any keyboard nav.  Then you'll
see that bug...

Would this include that the browser freezes while it is downloading mail?
Unfreezes when downloading mail stops (tested on pop3)
