Upgraded ISH using apk update / apk upgrade now FiSH no longer works

Hi

I just ran apk update and apk upgrade and now the Friendly Interactive Shell (FiSH) no longer works, can't run ls or clear in it, it just dies

Running Alpine Linux 3.12.0

Maybe do this?

echo “http://dl-cdn.alpinelinux.org/alpine/v3.13/main
http://dl-cdn.alpinelinux.org/alpine/v3.13/community
http://dl-cdn.alpinelinux.org/alpine/edge/main

http://dl-cdn.alpinelinux.org/alpine/latest-stable/community” > /etc/apk/repositories; apk update; apk upgrade

I'm getting a lot of "not found" errors by copying and pasting your answer into ish

Maybe I'm missing keys or something?

It's splitting your response by return character, hmm I'll need to take out the new lines

Maybe do this?

Having multiple versions of alpine is a bad idea; this is three. You should choose one.

I have a workaround. Downgrade to fish-2.6.0-r2 and apk add python2. This works whether or not you’re running Alpine v.3.12.x like you say you are, because the problem evidently relates to a stubbed syscall in iSH (91) and all of 1.1.2; BtW. apk foo does not “update/upgrade iSH”, only on Alpine’s apps and for apk’s repository list itself.

@62f

apk add fish-2.6.0-r2

Gives an error that the Aplinev3.13 main and community repos are unable to select the packages...

Any suggestions?

It seems that the clear command is not the only casualty; after one or two entries of any sort, any of the newer fish versions locks iSH up even ^C, then iSH cannot run any commands at all, although the web-based online help browser seems to work for extended periods. Despite the fact that I was using fish before, an update to musl seems to have nipped off that bud from a very low level across the board. Even using another of the prebuilt Alpine mini-filesystems to take the major version of Alpine down to the lowest possible subversion hasn't helped, and I presuppose that htop's only salvation also lies in retrograding its apk by several steps.

Just now it did seem as if I have found yet another workaround fish & fish which ran current versions of fish fairly well, until discovering any iOS task switch immediately freezes it. The latter versions log a 375 stub in dmesg with every command, while the working version offishdoes not.

iSH (1.1.2 build 100) & fresh fish:

still flaky & fried!

Bootingfish as iSH v101(1.1.2)'s default shell visually registers input yet output-wise remains catatonic.

Oddly enough, fish still responds to the TAB key to produce the predictive list of commands

Implicit example for a non-destructive app-regression : https://github.com/ish-app/ish/issues/1269#issuecomment-781817483 @StewAlexander-com "apk add fish-2.6.0-r2" is not how apk functions.

Maybe do this?

Having multiple versions of alpine is a bad idea; this is three. You should choose one.

I went with v3.13 and that solved all IO ERROR issues for me.

@josteink except that the OP title isn’t simply about fixing apk repository I/O errors, it’s about fish ‘dying’. #1320 is #1213 , not this bug.

Any progress with this? I can confirm that this issue still exists quite frequently, to the point where FiSH is unusable in any normal capacity.

I have it set as my default shell for the app and simply navigating around the file system with cd or checking running processes with ps will cause the described behavior. I can’t get it to happen consistently enough to determine a cause, but it definitely happens consistently enough to be unreliable. :(

iSH v1.2.2 (Build 178) and fish v3.1.2. From my testing here’s what else I can determine about this issue:

1. This error requires a command be run inside fish. Spamming the Return key without running a command prior never causes fish to die/freeze up. Additionally, fish doesn’t care if it’s the default shell or if it’s called from another shell, this seems to be consistent regardless of how you enter the fish shell.
2. This error seems to require multi-line output from fish to occur. I cannot get this error to occur if I run a command or any series of commands that simply output a single line of text then output the prompt. But if the command outputs multiple lines of text, or if the command outputs text not in a regular output flow—i.e., uses tabs like with ls—it seems like that can help cause fish to die either soon after or upon execution of that command. The issue also can prop up if you use the tab suggestions and there’s multiple columns and rows of suggestions, but it doesn’t fail if there’s only a single row of suggestions.
3. This appears possibly be related to how iSH renders outputs or handles text. I don’t know if that’s true, but there is a difference in when commands are run in ash vs fish. The prompt in fish noticeably takes time to appear while the ash prompt is always instantly there with no delay, no matter how fast the Return key is spammed. I don’t even know if this observation is something noteworthy or not towards this issue, but this ‘delayed prompt’ doesn’t exist in sh, bash, zsh, dash, csh or tcsh. It’s exclusive to fish.

@kgsbowtie

Sounds like #1273. Unfortunately I don't know of any way to fix it.

Any progress, how can I help?

This problem still exists, any progress?

Still looking on any updates here - @Practicalbutterfly5 are you still seeing the problem?

Yes still same problem.

@Practicalbutterfly5 😒, thanks for the update -- keeping this issue open until there's a fix or someone telling us that it can't be, and the reason

Hi! iSH 1.3 is out which might have resolved this problem (this sounds like the same issue described in #1764 and #2018). Could you please give it a try after updating, and let us know in the case you're still running into issues with fish? Thank you!

Tested this for a whole day, with all my fish plugins and customizations. Works perfect 👌 thanks!
