uv does not understand -Nholepunch as documented

[reduzent]

I would like to test setups where both uv instances are running behind a NAT. The wiki suggests that there is a holepunch method for the flag -N. So, I installed nat-helper and a STUN server on a server with a public address and tried to run uv as follows:

./UltraGrid-1.7.6-x86_64.AppImage --tool uv -r jack -s jack --audio-codec PCM --audio-capture-format channels=2 -P30104:11064:5016:5014 -Nholepunch:room=testi:server=telematic.zhdk.ch

and I get:

stat: /tmp/.mount_UltraGLQtNbO/usr/lib/libselinux.so.1: no version information available (required by stat)
UltraGrid 1.7.6 (tags/v1.7.6^0 rev c019d8b2 built Aug 23 2022 06:39:16)

[NAT] Wrong renewal interval: room=testi:server=telematic.zhdk.ch, minimal: 31
Exit

It looks like uv thinks room=testi:server=telematic.zhdk.ch is a renewal interval. Am I doing something wrong or is the documentation outdated?

Hello,

The holepunch method for NAT traversal is not yet available in the stable releases. To use it, please try the continuous builds.

Ah, good to know. Many thanks!

It works in my test setup. This is exciting!
