Bug 27231

Summary:	NFS client-side locking problem
Product:	Base System	Reporter:	quinot <quinot>
Component:	bin	Assignee:	Alfred Perlstein <alfred>
Status:	Closed FIXED
Severity:	Affects Only Me
Priority:	Normal
Version:	5.0-CURRENT
Hardware:	Any
OS:	Any

Description quinot 2001-05-09 18:10:00 UTC

	Many programs (such as mutt and the GNOME panel) that try to
	lock files on remote file systems exhibit various problems
	since NFS client-side locking was implemented.

	Specifically: mutt hangs when trying to lock the mailbox,
	and GNOME panel hangs (in fifoow) when trying to save its
	configuration file.

	The NFS servers are Solaris 2.6 and 2.8 boxen.

	I understand that this PR is very vague, but if anyone can suggest
	more specific tests, I'll be glad to experiment and report more
	precise results.

Please bring this issue up on -current. Because -current 
is a development branch, it's generally not considered 
a good subject of PR's.

I am still seeing this problem on -CURRENT as of:

FreeBSD shalmaneser.enst.fr 5.0-CURRENT FreeBSD 5.0-CURRENT #15: Thu Jun  7 17:54:30 CEST 2001     quinot@shalmaneser.enst.fr:/usr/obj/usr/src/sys/SHALMANESER  i386

[ Cc: GNATS so the PR can be reopened. ]

Thomas.

I 'implemented' locking, might as well take another shot at it. :)

I have done a few tests and was unable to reproduce the problem,
so it definitely looks good. I'll continue testing for a few days
and report the results.

Thanks for taking care of this issue!
Thomas.

Still no problem, so I guess this PR can be closed. :)

Thanks!
