157005 - DNS: resolution with large responses does not complete

Status: VERIFIED WORKSFORME

Description

[Anders Eriksson]

check out http://ftp.us.kernel.org/. The browser (1.0rc2) hangs forever trying
to resolve the name. A check with nslookup shows:


<shell>$ nslookup ftp.us.kernel.org
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.

which makes me think that perhaps mozilla (which has its own dns resolver,afaik)
does not handle large DNS responses correctly.

I'm runing on rehad 7.2, with
mozilla-nss-1.0rc2-0
mozilla-js-debugger-1.0rc2-0
mozilla-psm-1.0rc2-0
mozilla-1.0rc2-0
mozilla-dom-inspector-1.0rc2-0
mozilla-nss-devel-1.0rc2-0
mozilla-nspr-1.0rc2-0
mozilla-devel-1.0rc2-0
mozilla-nspr-devel-1.0rc2-0
mozilla-chat-1.0rc2-0
mozilla-mail-1.0rc2-0


Hope this helps!

wfm with win2k build 20020710..

Reporter:
Your build is too old. -> invalid

Please reopen if you see this with a recent build from mozilla.org. (1.1a or later)

we don't have a resolver, but we do have some higher-level caching.

Putting a large, (likely TCP-transfered) request into the testcases is something
I have wanted to do for a long time.

REOPEN: I'd like a WFM in linux. This could be a platform specific problem.

WORKSFORME.  Linux RedHat 7.2, Moz 1.0.1 and current trunk.
