Mac and linux (can't check windows) die going to MyNetscape.com. here's the mac
stack trace:

 Closing log
On windows, I can't reproduce the crash in viewer. But it does just load a blank
window. If I set EXPAT=1 in the runtime environment, apprunner will run, but
going to http://my.netscape.com give a blank window only.

This may be related to the other parser problem that waterson and hyatt have
been working on today. I'm adding them to the cc list.

Still happens for me, debug build, apprunner, 4/7/99.

Reopening bug.

Target Milestone: M4
Accepting bug.  Will look into it as soon as my build completes.
Setting milestone to M4...
Assignee: nisheeth → gagan
Status: ASSIGNED → NEW
So, as of 3 pm's cvs update today, no builds on any platform crash on My
Netscape.

All of the builds don't load the page properly, however.  On Win32, you see the
top part of the My Netscape page only if you set breakpoints.  If you run
without breakpoints, the top part of the page gets replaced by a blank window.

On Mac, the top part appears and then the webshell keeps getting netlib
notifications of url load progress.

I think Gagan should take a look at this bug.  I'm assigning this to him.
Meanwhile, I'll look and see what comes into the parser for this page...
Target Milestone: M4 → M6
Marking till Necko lands...
I still crash, debug build, 4/9/99. Something is wrong here.
I don't think this should be marked M6. We need My Netscape to load - we have
bookmarks to it. Changing to M4 and cc'ing important people.

We need a stack trace here. Could someone get it.

Since nisheeth was the initial owner of this, I am assigning it to him. Plus
gagan is on vacation.
for m4 we are going to have to punt on my.netscape.com.
its been removed from the toolbar.
we will add a release note items that several problems are under investigation
for this site.

I have tested My Netscape on a debug build of the M4 branch on Mac and Win32 and
they do not crash.  The Linux build does crash and the call stack is:

There are two separate problems with My Netscape.  One is network related and
one is layout related.  When I store a local copy of the my netscape page and
try to load it, the page loads fine but the layers that make up each box on the
page are not positioned properly; they overlap, creating unreadable content.
When I try to access My Netscape from the web, I get the same infinite loop
problem I commented about earlier.  The top part of My Netscape is rendered and
gets blanked out soon after.  Netlib keeps sending url load notifications to the
web shell and OnConnectionsComplete() never gets called.

To summarize:

Windows:
--------

Loading from web: Keeps cycling.  Only top part of page is displayed which is
blanked out soon after.  No crash.

Loading from local file system: Page displays.  Layout of layers is messed up.

Mac:
----

Same as for windows

Linux:
------

Loading from web: Crash in netlib with the call stack given above.

Loading from local file system: Same results as on Windows and Mac.

I am assigning this bug to Gagan to deal with the networking problem and marking
it M5 because of the crash on Linux.  I am going to create a new bug to deal
with the layout problems on the my.netscape.com page and assign it to me.
Deffered till Necko lands...
Target Milestone: M6
Per chofmann, we will put this on M6 and Release Note for M5 if still occuring.

Summary: crash going to myNetscape (viewer, apprunner) → crash going to myNetscape (viewer, apprunner)- Linux
Per DP's suggestion marking these till M8. Though Necko lands with M7, we will
be able to verify it for M8.

Summary: crash going to myNetscape (viewer, apprunner)- Linux → Linux/Gtk/NSPR: Timers misfiring
Renaming this bug so I can find it when I get more dups.
Can we try to look at this during M7, with an early copy
of necko?
*** Bug 7110 has been marked as a duplicate of this bug. ***
Summary: Linux/Gtk/NSPR: Timers misfiring → Gtk/NSPR: Timers misfiring
I'm moving this to target M9, Necko will be enabled somewhere during late M8 or
early M9.  We will need to get on this and it cannot be postponed past the M9
milestone.
Changing all Networking Library/Browser bugs to Networking-Core component for
Browser.

Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do
this in a bulk change.  If this happens, I will fix. ;-)
Summary: Gtk/NSPR: Timers misfiring → NECKO: Gtk/NSPR: Timers misfiring
Pl. verify with Necko.

My Netscape is now loading fine on all platforms (7/30 builds), if only we could
post and get our personalized pages :-)
Bulk move of all Networking-Core (to be deleted component) bugs to new
Networking component.
