117460 - Import of proxy-configuration from NN 4.75 causes error

Status: VERIFIED DUPLICATE of bug 115720

(Core :: Networking, defect)

Description

[Claudius Ohrt]

From Bugzilla Helper:
BuildID:    2001122106

After importing the proxy-configuration from NN 4.75 the settings are wrong and 
not changeable any more.
The prefs-line in Netscape Navigator prefs-file reads
user_pref("network.proxy.type", 3);
Having this line in the Mozilla prefs-file will cause an undefined 
proxy-configuration. If you could define a valid one there would be no problem. 
Unfortunately, Mozilla is not able to change this to valid entry.

Reproducible: Always
Steps to Reproduce:
1. Configure NN 4.75 to "no proxy"
2. Install Mozilla and import NN settings
3. Try to change Mozilla's proxy-settings

Actual Results:  Mozilla will not save proxy-preferences.

Expected Results:  The best solution would be that Mozilla will correctly import 
Netscape Navigator preferences in the first place.
It should at least be possible to correct the invalid entry afterwards.

networking? or profile migration?

This is probably a dupe of, or related to, bug 98234. cc'ing tingley to whom it
is currently assigned.

I think this is probably not a dup of bug 98234 (the value of '3' appears to be
the key here, which isn't what's going on in that other, highly confusing, bug.
 But if fixing this somehow made that go away, I wouldn't complain.)

Confirming this.  It could be fixed either in the migration code (catching the
bad value) or in the network code (nsProtocolProxyService could reset bad type
values to "no proxy" or some other default when it encounters them -- although
this shouldn't ever happen except after profile migration).  I'm tempted to send
it to migration, but I don't know the precedent for where the buck stops on this
sort of issue.

[As a side note, there are indications that profile migration for the proxy
stuff is under-loved:

Over to migration.  I do not think that every component should be looking for
bad preference values and reseting them.
