'bat cache --build' crashes on armv7 #1149

Closed eggbean closed 3 years ago

eggbean commented 4 years ago

I have been able to add a .tmTheme for Sublime Text with success, but I cannot get this .tmLanguage file working. It is for the configuration file language for Mikrotik routers.

https://github.com/Kentzo/MikrotikScript/blob/master/MikrotikScript.tmLanguage

Is there anything I can do to make this work?

I added the file to ~/.config/bat/syntaxes/ and did bat cache --build, but it didn't work. Is there anything more I need to do?

sharkdp commented 4 years ago

Does the syntax show up when you run bat --list-languages?

eggbean commented 4 years ago

No, it doesn't. Is the TextMate format for syntaxes not supported, like it is for themes? I have tried to use a ruby-based converter to turn it into .sublime-syntax format, but I haven't had any luck with it.

sharkdp commented 4 years ago

Ah, I missed that. No, it is not supported. You can use Sublime Text to convert it (see README here: https://github.com/sharkdp/bat/tree/master/assets)

eggbean commented 4 years ago

I had to get some help with the conversion, but I get a segmentation fault error when I try bat cache -b with the converted file.

This is the converted file: http://sprunge.us/NYvb7P

Apparently it's probably not a problem with the syntect library and could be bat specific?

sharkdp commented 4 years ago

It does work fine for me:

▶ wget -O ~/.config/bat/syntaxes/mikrotik.sublime-syntax http://sprunge.us/NYvb7P  
…

▶ bat cache --build
Writing theme set to /home/shark/.cache/bat/themes.bin ... okay
Writing syntax set to /home/shark/.cache/bat/syntaxes.bin ... okay
Writing metadata to folder /home/shark/.cache/bat ... okay

▶ bat --list-languages | grep Mikrotik
Mikrotik Script:rsc

Note that the file has Windows line endings. But it doesn't seem to cause any problems for me.

eggbean commented 4 years ago

I just tried again. Yes, it works on x86_64, but it results in Segmentation Fault on ARM.

I usually do router stuff on a Raspberry Pi which is connected to it. Not a major problem, as I could just use my laptop instead, but is this something I could resolve?

eth-p commented 4 years ago

A segfault? That (likely) isn't going to be happening somewhere in our Rust code, as we don't make much use of unsafe.

I suspect this is going to turn out to be an issue with a dependency, but I don't have an ARM platform to test it on. Are you able to get us a stack trace, and is there any more info you can give us about your platform?

E.g. Processor model, was bat compiled with armhf, etc.

sharkdp commented 4 years ago

A segfault? That (likely) isn't going to be happening somewhere in our Rust code, as we don't make much use of unsafe.

Another option could be an illegal instruction if the executable was compiler for a non-compatible platform. But that would usually trigger a SIGILL.

eggbean commented 4 years ago

Sorry, I forgot to reply earlier. It's a Raspberry Pi 3B, so it has a Quad Core 1.2GHz Broadcom BCM2837 64bit CPU. It's running Raspberry Pi OS and I think the package must be from the Debian repository.

This is the output of strace. Is this enough? http://sprunge.us/CGV3Wv

sharkdp commented 4 years ago

Interesting. It looks like it crashes directly after the whole mikrotik.sublime-syntax has been successfully read.

The next step inside syntect (the library which does the syntax highlighting and manages sublime syntaxes) is the serde deserialization from YAML to an actual Rust object (no, syntect does not use serde_yaml for that). Maybe something goes wrong in this step? I will try to debug this on a RPi.

sharkdp commented 4 years ago

@eggbean Maybe you could run bat with gdb (even if it's not a debug build) to get a partial backtrace?

> gdb bat
gdb> run cache --build

# wait for it to crash

gdb> backtrace

Ahh, damn. That's not very helpful, unfortunately.

I went ahead and tried to reproduce this on my RPi 3b. I see the exact same crash as well!

Next, I tried to minimize the mikrotik.sublime-syntax file, to see if it is actually related to the content. Turns out it is! This is the "minimal" example which still leads to a crash:

This lead me to think that it would be related to the regex engine (oniguruma) - which is actually a C dependency and may very well segfault. Indeed, I was able to reproduce the error with this simple program:

with the following Cargo.toml file:

[dependencies]
onig = { version = "6.0", default-features = false }

which I cross-compiled via

cross build --target armv7-unknown-linux-musleabihf
sharkdp commented 4 years ago

I would suspect that it's also possible to reproduce the error with a simple C program, but I don't have a full-fledged dev. environment on my RPi and I don't really want to go down the route of cross-compiling a C program.

Maybe this is a bug that only appears on 32bit systems? (ARMv7 is 32bit). I think it should be reported upstream, but it would be great to get some confirmation first. The following C program should maybe lead to the crash on ARMv7:

#include <stdio.h>
#include <string.h>
#include "oniguruma.h"

extern int main(int argc, char* argv[])
{
  int r;
  regex_t* reg;
  OnigErrorInfo einfo;
  OnigEncoding use_encs[1];

(if someone wants to try this, I cloned the oniguruma repo and modified the samples/simple.c program. The examples can be built with cmake)

@eggbean: as a workaround for now, you could try to tweak (or remove) this long regex from the converted sublime syntax such that the segfault does not appear. Another option would be to build a fancy-regex-version of bat. Note, however, that some other syntaxes might not work as expected.

I think I will have to wait in hope that this apparent bug gets fixed and use my laptop instead in the mean time. Tell me if there is anything else I can do, but I would need instructions. Thanks for your help.

If I pin the version of onig_sys to 69.5.1, I can actually reproduce the crash with cross run (which is just fantastic: it cross-compiles the code for ARM and then executes it with QEMU):

▶ cross run --target armv7-unknown-linux-musleabihf 
    Finished dev [unoptimized + debuginfo] target(s) in 0.03s
     Running `qemu-arm /target/armv7-unknown-linux-musleabihf/debug/onig-segfault`
Segmentation fault (core dumped)

If I use the latest version of onig, I can not reproduce the crash. Seems like this problem has been fixed upstream. This should fix it in bat as well: #1495
