16:44 <sewn> why does foot --server occasionally die with "failed to dispatch pending Wayland events: Broken pipe" through out the day?

16:48 <dnkl> the compositor is killing the connection

16:48 <vyivel> sewn: because the compositor has closed the connection, probably due to a protocol error

16:57 <sewn> arent clients able to print out a protocol error before they die?

17:09 <aljustiet> Yay, I can know search gentoo wiki directly from the url bar

17:28 <vyivel> sewn: wl_display.error handler does that

17:29 <vyivel> there's also wl_display_get_protocol_error() except it doesn't provide the message

18:19 <constxd> hi any any terminal experts there?

18:25 <jpp> Ask your question and we'll see!

18:26 <constxd> i am wondering how does ioctl() work. or win32 Console API calls. how is it possible that a windows program on a remote machine invoking SetConsoleMode() can, over an SSH connection, cause my local terminal running under linux to change into raw input mode? question applies to TIOCS ioctls as well

18:28 <constxd> surely it isn't just writing some bytes to the pty or it wouldn't be a syscall

18:30 <bapt> m

19:16 <rockorager> constxd: It doesn't change your local terminal

19:17 <rockorager> The terminal is dumb, it moves the cursor and places text on the screen

19:21 <constxd> rockorager: it must change my local terminal

19:28 <rockorager> constxd: why do you say that

19:33 <rockorager> If you use bash as your shell, it doesn't reset the terminal mode. from bash, ssh into a machine. make sure you are in bash again. `stty raw`. type and press enter, you will see you are in raw mode

19:34 <rockorager> kill ssh from your local machine

19:34 <rockorager> in bash, press some keys and you will see you are not in raw mode

19:36 <rockorager> https://asciinema.org/a/HKxR0amJjDnZewVU2gv6j0H9u

19:41 <constxd> rockorager: ok so then what is happening

19:41 <rockorager> what do you mean

19:41 <constxd> foot -> bash -> ssh -> bash -> ./my_prog

19:41 <constxd> i am in cooked mode

19:41 <constxd> my_prog calles tcsetattr()

19:42 <constxd> suddenly i am in raw mode

19:43 <rockorager> the remote pty is in raw mode

19:43 <constxd> hmm

19:43 <constxd> so foot doesn't behave differently at all

19:44 <constxd> it always writes to the pty immediately as soon as you press a key. and cooked/raw is purely in the kernel pty layer

19:45 <rockorager> yes

19:45 <constxd> but what about TIOCGWINSZ surely that requires some action from foot

19:47 <rockorager> signals work over ssh

19:48 <constxd> is it that foot called TIOCSWINSZ earlier and the kernel remembers the window size

19:49 <constxd> like ultimately only foot can know how many lines and columns there really are

19:49 <rockorager> or rather, ssh forwards that signal

19:49 <rockorager> https://www.ietf.org/rfc/rfc4254.txt

19:49 <rockorager> section 6.7

19:50 <rockorager> So ssh locally catches the SIGWINCH, sends that message, and the remote pty changes size

19:51 <constxd> ok i think i get it now

19:51 <constxd> ty

19:53 <rockorager> np
