Suspend doesn't work in cmd
Hi, Control keys doesn't seem to be working correctly under cmd. STR: 1. Run bash in cmd.exe 2. Run anything, in my case "seq 1 10" 3. Try to suspend job with CTRL+Z or suspend printing with CTRL+S Ii will ignore request. Works in mintty, doesn't in cmd.

I though I lost it, because indeed there is prerequisite. It fails when there is at least one pty allocated. STR: 1. Open mintty (will allocate pty) 2.

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.

Console doesn't work correctly under anything else than cmd or mintty
Hi, I was testing latest master (e637d53) and console is clunky in anything that isn't cmd.exe or mintty. I tested Microsoft Terminal and ConEmu. For example navigating with arrows doesn't work in vim. In zsh searching history with up arrow when there is beginning of the command doesn't work. And so on, sometimes Home button doesn't work to jump to beginning of the line or Backspace to clear input. It used to work better. I have tried CYGWIN=disable_pcon but didn't help really. Is it known problem? Is there a workaround? Should this be fixed in Cygwin or somewhere else?

Re: "tmux open terminal failed: not a terminal" in terminal emulators other than mintty
> 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
Re: ACL: Why SYSTEM doesn't have full access set on newly created files?
> It is easily fixable by mounting directories outside Cygwin tree with "noacl" flag. > It is even required to do so, if you expect interoperation between Cygwin and > native tools. Indeed, this is acceptable workaround for me. Then again it is not really interoperable out of the box, even tho it may looks like. I mean all Windows drives are mounted, you can easily jump through all directories, mess with them until you find that it doesn't work and it is " required" to access those files differently. One may be fooled by the seemingly no boundary between Cygwin and Windows. > Don't do that on Cygwin directory tree, you break Cygwin doing this. I was talking about project cloned outside Cygwin tree, by using Cygwin's git. I do understand that Cygwin sysroot is it's own thing. Also the Cygwin tree have let say "normal" permissions set. I mean there is not deny on SYSTEM and so on. > Answered multiple time in the last 20 years. Read the docs. If it were so easy to find. And it was changed like 5 years ago how ACLs are handled, so I really doubt it was described 20 years ago. I just wanted to understand why SYSTEM described in Cygwin's docs as "A special account which has all kinds of dangerous rights, sort of an uber-root account." have those rights limited. > They are in correct order. Just not canonical order, which Explorer only supports. I was not implying they are in incorrect order...

ACL: Why SYSTEM doesn't have full access set on newly created files?
Hi, I know that Cygwin tries to emulate UNIX permissions using ACL. But I don't understand why SYSTEM doesn't have Full Control allowed or even modify. Shouldn't generally SYSTEM have access to everything? I have cloned git repository of UWP application, and deployment fails in VS with error: "DEP0700: Registration of the app failed. [0x80070005] Deployment Register operation with target volume F: on Package ... from: (AppxManifest.xml) failed with error 0x80070005." It is easily fixable by adding Full Control for SYSTEM on all files, but that wasn't my first idea, so it took some time :) Long story short, it fails and might be not obvious for the user why, at the first glance. Also when accessing ACL from Explorer it throws: "The permissions on are incorrectly ordered, which may cause some entries to be ineffective." And forces me to reorder them if I want to edit. That said, I have three questions: 1. Could Cygwin by default give SYSTEM full control? If not, why? 2. Could Cygwin put ACL in order, so Windows doesn't complain about it? 3. Do we need "NULL SID" entry? -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
"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?
