27975 - [meta] "Conn:" network availability features

Status: RESOLVED WORKSFORME

(Core :: Networking, defect, P3)

Description

[Warren Harris]

Currently we don't deal very well with the the absence of a network connection. 
We hang on unix, and bring up the dialer on Windows. (Not sure about Mac.)

I understand that Travis might have access to some code to implement this for 
Windows. Assigning to him for now. 

See bug 7428 about the hang on unix. Bug 21835 about SetOffline (an 
alternative perhaps).

Reassigning all travis bugs to Valeski for triage. Don thought these were
all docshell related. Travis is no longer at netscape so these bugs are
unowned.

I'm reassigning 23 bugs to Valeski right now. To search for them,
search for "BUGSFORMERLYKNOWNASTRAVIS" in the description. The url below 
should work.

mass move, v2.
qa to me.

Comment 4

[benc]

Early bug number, no mindlessly long discussion... so I'm going to meta all the
general connectivity bugs here.

Comment 5

[Matthew T (active 1999-2002)]

These sorts of bugs?

Comment 6

[benc]

Sure. Hopefully I can clean everything up at once this week...

Comment 7

[benc]

Ha ha. "last week"...

Okay, I'm working on this more now...

Here's a summary of what I am looking at:

1- Behavior if disconnected (no PPP or PPPoE connection when launched).
2- Behavior when network changes.

Since these problems are often system specific, I'm creating one bug per OS per
feature.

If necessary, I might create an intermediate layer of meta bugs per feature that
glob the OS bugs, since that is the most likely way people will want to fix
problems.

Lots of thse bugs are lying around the component, so the dupe cleanup maybe out
of order, even though I prefer to dupe to the lowest number bug, it may not be
possible this time.

Since we are a network application using the system stack, the basic model is
that we call for data, and if it doesn't come back, we should error accurately,
and if possibly helpfully.

Assuming all basic network errors in an environment with good connectivity work,
the most basic bug needed is: bug 164715.

Some operating systems offer dial-on demand features. If we can work with them,
we should.

Mac OS X has dial on demand, but the implementation is not transparent. See bug
150729. 

I'll continue to add more information here.

Mozilla 1.1 and Netscape 7.0 seem to do dial on-demand in Win98. I do not recall
this working before. 

I do not use dialup on my Linux system currently, so if someone could help, that
would be great.

Quick-launch and VPN software are two other items that need to be addressed.

Comment 9

[benc]

Refresh of DNS servers, needed for continutity of DNS service after switching
networks, seems to work correctly in Win98 and somewhat (as mentioned above) in
Mac OS X.

In Linux, it seems to be broken, after being fixed for a while. I need to verify
the fix with an old build, then file or find a new bug for the regression.

adt: removed nsbeta1 nomination.  Please nominate individual bugs as appropriate.

Comment 11

[benc]

The DNS problem was fixed some time ago.

:bagder has done a lot of work here.. followups with specifc action items welcome.
