221063 - 100% CPU loop when subscribing and profile's News directory has not been created

Status: RESOLVED EXPIRED

(SeaMonkey :: MailNews: Message Display, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030908 Debian/1.4-4

Since I can't get trn working, I fired up 1.4 and tried to subscribe to a Moz
newsgroup.  When I clicked on "Retrieve messages for account," everything
instantly hung with the CPU getting smoked; strace showed

open("/home/pme/.mozilla/default/jx7zv382.slt/News/news.day.sbcglobal.net/netscape.public.mozilla.unix.msf",
O_RDWR|O_CREAT|O_TRUNC, 0666) = -1 ENOENT (No such file or directory)
stat64("/home/pme/.mozilla/default/jx7zv382.slt/News/news.day.sbcglobal.net/netscape.public.mozilla.unix.msf",
0xbfffee80) = -1 ENOENT (No such file or directory)
unlink("/home/pme/.mozilla/default/jx7zv382.slt/News/news.day.sbcglobal.net/netscape.public.mozilla.unix.msf")
= -1 ENOENT (No such file or directory)
stat64("/home/pme/.mozilla/default/jx7zv382.slt/News/news.day.sbcglobal.net/netscape.public.mozilla.unix.msf",

0xbfffee80) = -1 ENOENT (No such file or directory)

and so on, over and over.

The "News" directory never existed.  Making that directory and the nntpserver
directory under that one by hand allowed Mozilla to break out of its loop and
retrieve the messages.


Reproducible: Always

Steps to Reproduce:
1. If you have a news directory in your profile, delete it.  (I didn't have one,
but I presume that Mozilla is simply assuming it's already there, created by...
something else...)
2.  Subscribe to a newsgroup and get the list of postings.  Have a second CPU
handy, you'll need it.
3.  mkdir the missing profile directories.

Actual Results:  
Infinite loop.


Expected Results:  
Better error handling.  No assumption making.  Actually check that directories
exist before traversing them.



This profile was /not/converted from a Netscape profile or anything like that. 
Maybe that's what normally creates the news dir?
