Description Erwan David 2010-03-15 12:30:08 UTC 
latest tmux port does not work with either zsh or sh : shell has display
problems, and session may even block (seen when using less).

How-To-Repeat: tmux new-session with zsh or sh as shell : prompt does not appear. After
several press on return it may appear but line editing is broken.

Hi,

   Would you give a more detailed description of how about
the error produced ? I tested with sh and csh, it work well.

Hello Wen & Co.

I can confirm seeing this bug in tmux 1.2 on a relatively recent releng_7/amd64 jail.

All shells seemed to be affected, with or without special tmux configuration (I use the screen-like bindings, but the bug was present with and without them).

Have rolled back to tmux 1.1 now which fixes the issue.

It looked like there was an issue with screen updating - you typed something in and nothing echoed back. Starting a fresh tmux session just came back with blank screens.

Regards,

Alex

I was told it works on FreeBSD 8, but I am under 7.2, and cannot upgrade OS 
right now.

Symptoms are the same for any shell :

tmux new-session : nothing is shown
Return -> % is written
Return -> prompt is written
then cycle, return after a command shows a %, then return->result then 
return->prompt

When a command issues more than 1 page result everything is blocked in the 
client

C-b d detachs, then tmux kill-session kills everything.

TERM variables are OK : xterm-color before launching tmux (ssh from MacOS X 
terminal.app or from an xterm under linux), screen inside tmux

Hi all,

I'm seeing the same issue.  My uname -a is

FreeBSD eponine.barakmich.com 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Wed 
Apr 23 01:45:39 PDT 2008     
root@fantine.barak.photonzero.com:/usr/obj/usr/src/sys/BARAK0AMD64  amd64

Erwan's description is the same as mine -- blank screen; pressing 
"Enter" a few times shows % followed by an (older) prompt line. I have 
tried many different shells, and the result is the same.

I can confirm I tried it on FreeBSD 8.0-RELEASE inside a virtual machine 
and tmux 1.2 worked just fine, so there's something subtly different.

Downloaded and compiled my own copy of tmux 1.1 and it didn't show any 
trouble. I wonder what changed?

On #tmux, I got the following info :
setting export EVENT_NOKQUEUE=1 and everything works.
It seems tmux hits a bug on FreeBSD 7 kqueue implementation.
It should work better with defining HAVE_BROKEN_KQUEUE in configure for 
FreeBSD 7.
