Scrolling up works, but not down

[paps]

Currently on an unstable Debian, I'm using tig (version 2.0.2) in tmux (version 1.9) in xterm (version 308).

In my .gitconfig I have:

[tig]
    mouse = true

Moving with the arrow keys and JK works as excepted. Scrolling with the mouse wheel to go up also works as expected. However scrolling down with the mouse wheel does nothing...

Mind you, my mouse wheel works well everywhere else, be it in vim or tmux to scroll buffers (up AND down).

So, do you have any idea of what can cause this?

Thanks :)

I've tested with tmux 1.8, xterm 297 and tig 2.0.2 on OS X and have not able to reproduce it.
Will try to test on Ubuntu tomorrow.

To rule out any local configuration, could you try starting tig with?

TIGRC_SYSTEM= TIGRC_USER= tig

[paps]

Nope, still having the issue

I've been able to reproduce this with Ubuntu 14.04 in both xterm and gnome-terminal. Not sure if this is a problem in ncurses, the term database or the environment. Mouse events read with getmouse() when scrolling down simply returns ERR.

Curious if there's any fix for this yet?

@raduma No, I've not been able to figure out what is causing this issue. What version of ncurses, xterm, tmux, tig are you using?

[raduma]

Running tig on ubuntu trusty 14.04. It repro's when I run it directly under xterm, or when I run it via ssh from my macbook iterm2, or when I run it through tmux, either through xterm or ssh. Versions of stuff:

• tig version 2.0.3-12-gd4d11fa
• Xterm(297)
• tmux 1.8

Not sure exactly how to check the ncurses version. Maybe this?
$> ncurses5-config --version
5.9.20140118

Let me know if I can do anything to help you debug this. Happy to build and debug things locally if needed.

I'm getting this as well, running the latest tig on Linux Mint 17.

I have a feeling it's a curses problem. I ran this sample code and I'm getting the same issue.

Scrolling up works correctly (I get "Get mouse was ok"). Scrolling down shows "getMouse failed".

Versions:

• Xterm(297)
• ncurses: 5.9.20140118

Also happens on Xubuntu 14.04.

Thanks for giving this some more testing. I arrived at the same conclusion when I looked at this a while back.

I also have this problem on Arch Linux.
xterm: 322
urxvt: 9.22
ncurses: 6.0
tig: 2.1.1

Are there any news on this? Should this be reported upstream?

The same behavior on Fedora 22, tig 2.11, gnome-terminal 3.16.2 and ncurses-5.9-18.20150214

I've digged it a bit. The problem is ncurses is built without --enable-ext-mouse in e.g. Debian and with old events encoding there is no way to represent button5. Details:

Up and down is Ok, bug left and right not work. Can you support it?

Mac, iterm2 Build 3.1.5
