`sk` suddenly stop working (no response) #308

JodyStats · 2020-04-20T14:12:01Z

Hi, I am a big fan of Rust and has since moved to sk from fzf. Thanks for the great work.

Before updating 0.8.1, sk was working fine at all. After updating, all of a sudden it just stops working. sk does not have any response. I use fzf side-by-side with sk and fzf is still working as normal.

Using pacman. I removed skim. Reinstall it. Issue persists.

# Start cleanly
bash --noprofile --norc

@JodyStats Would you please turn on the log and try to reproduce?

RUST_LOG=debug sk 2> x.log

And paste the content of x.log here?

JodyStats · 2020-04-21T02:10:37Z

Sure. I also did both RUST_LOG and strace for ya

@lotabout The issue is v0.8.1 released a month ago. I install v0.8.0 from source and sk works per normal

mkdir ~/dev
cd ~/dev
curl -LJO https://github.com/lotabout/skim/archive/v0.8.0.zip
unzip skim-0.8.0.zip
./skim-0.8.0/install
export PATH="$PATH:$HOME/dev/skim-0.8.0/bin"

sk --version
# 0.8.0

sk
# It works
sk
# It works
sk
# It works

kvnxiao · 2020-05-30T08:59:07Z

I am also having this issue with 0.8.1

lotabout · 2020-06-25T02:55:32Z

@JodyStats It's been quite a while. I tried to reproduce this issue with archlinux docker image but failed to reproduce.

# cat /etc/os-release
NAME="Arch Linux"
PRETTY_NAME="Arch Linux"
ID=arch
BUILD_ID=rolling
ANSI_COLOR="38;2;23;147;209"
HOME_URL="https://www.archlinux.org/"
DOCUMENTATION_URL="https://wiki.archlinux.org/"
SUPPORT_URL="https://bbs.archlinux.org/"
BUG_REPORT_URL="https://bugs.archlinux.org/"
LOGO=archlinux

Could you please download the pre-built packages and check if you could reproduce?
https://github.com/lotabout/skim/releases/tag/v0.8.1

And also the frequency of this problem? Thanks!

kvnxiao · 2020-06-25T06:52:48Z

@lotabout
Using sk downloaded from the pre-built 0.8.1 (skim-v0.8.1-x86_64-unknown-linux-gnu.tar.gz), it simply stops responding through my ssh connection to my Ubuntu 20.04 LTS (GNU/Linux 5.4.0-37-generic x86_64) server.

It simply hangs, and I am unable to provide input to it. I cannot Ctrl+C it either.

~~So the frequency of this problem is every time I try to use sk, meaning that I am actually unable to use it in its entirety.~~ This issue occurs about 8/10 times when trying to launch sk, which is the majority of the time.

There is also no output during the hang when I attempt to use RUST_BACKTRACE=1 RUST_LOG=debug sk 2> x.log:

[2020-06-25T06:46:18Z DEBUG sk] query_history_file: None
[2020-06-25T06:46:18Z DEBUG sk] cmd_history_file: None
[2020-06-25T06:46:18Z DEBUG sk] query_history: []
[2020-06-25T06:46:18Z DEBUG sk] cmd_history: []

# END OF LOG

For what it's worth, I am accessing my server through ssh on a Windows 10 desktop.

EDIT:

I have even built the binary from source using cargo install skim, which builds v0.8.1, and the same results are happening.

lotabout · 2020-06-25T07:00:12Z

@kvnxiao Happens every time?

kvnxiao · 2020-06-25T07:00:25Z

Yep, every time.

lotabout · 2020-06-25T07:02:21Z

@kvnxiao Thanks for the information. I'll try to grab a Ubuntu 20.04 to reproduce.

kvnxiao · 2020-06-25T07:09:23Z

Also just attempted to test 0.8.0, and would mention that this issue happens to 0.8.0 too (where I have to pkill sk to terminate it from hanging), but approximately 1-2 times out of 10 tries, it works. The rest of the time it hangs.

kvnxiao · 2020-06-25T07:15:55Z

@lotabout I apologize, my previous comment saying that it happens every time in v0.8.1 is incorrect. It does start up on v0.8.1 only sometimes (to the same effect as 0.8.0).

I took a screen recording of my terminal sessions on 0.8.1, please take a look:

lotabout · 2020-06-26T01:01:47Z

@kvnxiao Would you please help me to reproduce with RUST_BACKTRACE=full RUST_LOG=trace sk 2> x.log and post the log?

Also, it would be great help if you could rebuild skim with debug symbols enabled before reproducing. (set debug=true in skim's Cargo.toml)

[profile.release]
lto = true
debug = true

I've tried to setup a Ubuntu 20.04(virtual machine) + ssh (from mac), no luck with reproducing.
I know there could be potential dead locks with tuikit but unable to locate the exact line.

kvnxiao · 2020-06-26T01:06:14Z

This is all I see after building with debug = true and using RUST_BACKTRACE=full RUST_LOG=trace sk 2> x.log

After this, it hangs, and I have to sudo pkill sk, and the log is still the same.

kvnxiao · 2020-06-26T01:08:11Z

When it does work in the off chance,

these are the logs I get:

lotabout · 2020-06-26T01:08:54Z

@kvnxiao Thanks, I'll have a look.

lotabout · 2020-06-26T02:14:16Z

@kvnxiao Could you try the below pre-built version? Expectation: the below package would fix the issue.

skim-debug.tar.gz

If you worried about the pre-built image, would you please try:

git clone -b fix/init-hang git@github.com:lotabout/tuikit.git

modify skim's Cargo.toml

tuikit = {path = "../tuikit"} # point to the cloned tuikit repo

cargo build --release
use the binary ./target/release/sk to reproduce.

lotabout · 2020-06-26T02:22:28Z

@kvnxiao However I believe your case is different with @JodyStats 's.

Your logs shows that skim(tuikit) is waiting for the cursor position(^[<row>;<col>R) while the report is not complete.

[2020-06-26T01:05:21Z TRACE tuikit::input] next_key_timeout
[2020-06-26T01:05:21Z TRACE tuikit::input] get_chars: buf: [27]
[2020-06-26T01:05:21Z TRACE tuikit::input] get_chars: buf: [91]

So that sk hangs on waiting for the remaining keys. The above fix should avoid the hanging situation, but you may still get the wrong cursor position since the report is still not complete.

While in @JodyStats 's case it might be some dead lock caused by a thread panic. Which I also failed to reproduce.

kvnxiao · 2020-06-26T02:24:39Z

@lotabout Can confirm that the new binary you uploaded works 100% of the time (at least when I tried to start sk about 20 times)

lotabout · 2020-06-26T02:25:26Z

@kvnxiao Thanks! I'll commit the changes to master.

kvnxiao · 2020-06-26T04:02:16Z

@lotabout Thanks! could you also publish the 0.8.2 update on crates.io?

lotabout · 2020-06-26T06:42:37Z

done.
