Sorry. > Hi, I did take a look how tmux works and what is going on in Cygwin. Here is short summary of my findings. * Tmux sends each client stdio fd to the server through socket. Cygwin does not support passing file descriptors over to other processes so this fails. * Tmux has a hack for Cygwin where it opens tty by name provided by client... And now there are two cases: 1. When there is no pseudo terminal. cmd.exe, (WT and most other terminal emulators out there) * Tmux server will try to open /dev/cons by name provided by client, but this fails with ENOENT, because server process doesn't see this device. 2. When there is allocated pseudo terminal * Tmux server will try to open /dev/pty by name provided by client and actually work. Is there a way to make tmux work with /dev/cons? I have seen in docs /dev/cons1 Console device names are pseudo device names, only accessible ... from processes within this very console session. This is due to a restriction in Windows. So it likely means that whatever we do it will not be accessible from another process. Is this docs still holds true in latest Windows? I have seen a path to always allocate pty for native applications, maybe this would actually resolve this problem too.

> You can try another pty emulator. F.e. wintty. Not really interested in some dead projects ;p Let me rephrase the question, because I misspoke. Currently Cygwin works acceptably only under Mintty as far as I can see. Running it from cmd or any of terminal emulators listed before result in sub-par performance. Even things like Home button to move cursor doesn't work, as originally stated tmux doesn't work and so on. Now that Windows is making improvements to their console https://devblogs.microsoft.com/commandline/windows-command-line-introducing-the-windows-pseudo-console-conpty/ it may be good time to improve Cygwin's compatibility. Since my first mail I looked at git log and seen pty related changes, compiled latest Cygwin, but it doesn't work better and even worse, because mouse stopped working over ssh in tmux. That said, I guess my really questions are: 1. Is the goal to improve Windows console compatibility? 2. If yes, what is the current status and challenges? 3. And my original question will the tmux work? :) Projects like Windows Terminal are convenient way to have PS, CMD, Cygwin and its child MSYS in one window hence I am wondering if it will be possible without drawbacks. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

"tmux open terminal failed: not a terminal" in terminal emulators other than mintty
Hi, I'm not exactly sure who to blame for this issue, but I figured I will ask you guys. Tmux fails to open in anything else than mintty it seems like. It works from ssh session, probably because pseudo-tty is allocated, but except that tmux will fail. There are multiple reports about that, without solutions: https://github.com/cmderdev/cmder/issues/453 https://github.com/alacritty/alacritty/issues/1687 https://github.com/zeit/hyper/issues/3608 https://github.com/microsoft/terminal/issues/5132 Do you think we could make it work without using mintty? If yes, should the changes be made in the Cygwin, tmux or terminal emulator code? Any pointer would be good so I can poke others :) Thanks, Kacper -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
