STDIN.raw changes stty mode #2065

It is still raw mode after STDIO.raw call but i expect it to match the mode used before the call.

It is not documented, but i guess IO.raw! should change stty mode, and IO.raw shouldn't.

The text was updated successfully, but these errors were encountered:

We have to review STDIN.raw, it was introduced when IO was blocking. Now that it's non-blocking, I don't know if that still works, has bugs or what. My guess is that it's completely broken.

This does not confirm nor refute @asterite 's last comment about reviewing how STDIN.raw works, but it makes sense to review. The methods in question were most recently touched by #2442 where it may have fixed this issue. I have not yet confirmed this.

It does not work for me. It may be dependent on OS or shell (I'm on OS X and zsh):

@veelenga This now seems more likely a zsh-induced issue, since the stty settings amy be set/overridden on a terminal-by-terminal basis.
Can you reproduce with bash, to isolate? I tried a naive install of zsh 5.2 (no special profile settings) and was unable to do so.

@miketheman you are right, this seems to be zsh-induced issue:

I believe that STDIN.raw is NOT the issue here. I think it's a red herring. Doing ANYTHING in crystal appears to screw up the mode. I stumbled across this yesterday when working on a git commit hook. I haven't yet pinned down a way to prove that it's the modes being screwed up but the evidence is strongly suggesting it.

the reason i can't prove it (yet) is that my crystal script in its entirety is as follows:

exit(0)

If i make a commit hook in bash, python, or anything else that just exits, everything is fine. Make it in crystal and something is borked.

My bash script in its entirety

#!/bin/bash

exit 0

Check out this
example video to see the practical effects of borking the mode.

I will readily admit that there is a possibility that this is being exposed because of my particular vim configuration, or by the fact that i use Fish shell, but that's not the point. The point is that the modes are being screwed and it's not possible to write a crystal app that does NOT screw them, but you can in any other language.

If anyone can suggest a way to prove without a doubt that it's the mode I'm all ears. Currently i'm wondering if i can convince git to execute something that would write the mode into the commit template.

And yes, if i run the crystal script NOT as part of a git hook then using vim immediately afterwards in the same terminal works fine. So, there's something that lingers when in that particular chain of events that makes this consistently reproducible.

masukomi · 2016-08-16T15:27:33Z

This issue is a big deal to me. I've been writing a cli tool that I really want to use a git hook, to solve some problems at work. I'm happy to go poke the compiler to try and fix it, but this isn't an area I'm particularly familiar with. If someone could help point me in the right area of the code to get me started I'll see if i can improve things, but with the exit(0) code seemingly causing the issue i'm just not sure where to start.

jhass · 2016-08-16T15:35:47Z

A good starting point should be attaching a strace to see what it does to the IO.

Sija · 2016-08-16T15:37:28Z

@jhass Assuming that's the Linux env we're talking about.

jhass · 2016-08-16T15:37:57Z

well, other platforms should have similar tools.

FWIW here's what I get.

You can see the ioctl calls setting the terminal modes.

ioctl(0, TCGETS, {c_iflags=0x6506, c_oflags=0x5, c_cflags=0xbf, c_lflags=0x8a3b, c_line=0, c_cc="\x03\x1c\x08\x15\x04\x00\x01\x00\x11\x13\x1a\x00\x12\x0f\x17\x16\x00\x00\x00"}) = 0

Here we query the current state before setting the raw mode.

ioctl(0, SNDCTL_TMR_START or TCSETS, {c_iflags=0x6004, c_oflags=0x4, c_cflags=0xbf, c_lflags=0xa30, c_line=0, c_cc[VMIN]=1, c_cc[VTIME]=0, c_cc="\x03\x1c\x08\x15\x04\x00\x01\x00\x11\x13\x1a\x00\x12\x0f\x17\x16\x00\x00\x00"}) = 0

This sets the raw mode

ioctl(0, SNDCTL_TMR_START or TCSETS, {c_iflags=0x6506, c_oflags=0x5, c_cflags=0xbf, c_lflags=0x8a3b, c_line=0, c_cc="\x03\x1c\x08\x15\x04\x00\x01\x00\x11\x13\x1a\x00\x12\x0f\x17\x16\x00\x00\x00"}) = 0

and this restores the FD exactly like it previously was.

Now onto:

Which set stdout (1) and stderr (2) into non blocking mode. This is probably done by libevent2, we should look into whether it has a teardown call that would undo it.

But I'm not certain it can affect the parent process.

You can try to unset it manually to see whether it makes any difference:

STDOUT.blocking = true
STDERR.blocking = true

masukomi · 2016-08-18T03:39:38Z

setting STDOUT and STDERR to blocking absolutely fixed my problem @jhass. Thank you! What's particularly interesting (to me at least) is that setting either of them to blocking fixes it. It doesn't seem to matter which one, as long as ONE is set that way.

I'd be curious if this fixes @veelenga 's problem too.

Also, I'm not sure if we have 2 different problems, or if the STDIN.raw thing isn't just a red herring. I feel like that @veelenga may have just found another decent way to exercise the problem and capture it.

The practical effect of this was that it screwed up vim when you used changelog_manager as a pre-commit hook. details here: crystal-lang/crystal#2065

acook · 2016-12-25T01:56:53Z

I just spent a couple of hours debugging a terminal redraw issue. Since I'm writing a commandline utility I assumed it had something to do with my terminal escape codes. Imagine my surprise when I discovered I could replicate the issue with touch empty.cr && crystal run empty.cr!

This issues breaks less and vim's ability to reliably draw, including git diff!

My workaround is to put @jhass's code into an ensure block before exiting.

For future reference I'm on Crystal 0.20.3 (2016-12-23) built through Homebrew on macOS 10.11.6 and iTerm2 3.0.13.

Terrible bug. Please fix this or point me to where I can fix it myself (presumably in the teardown code).

NOTE: This bug also affects the crystal command itself.
NOTE2: To workaround the issue with the command, you can do crystal <args> | tee /dev/null. This stops it from changing the state of the terminal.
