Segmentation fault when precompiling assets

gabo-cs-zz commented 4 years ago

Sometimes, when I make some changes to my .scss files in my Rails 6 app, I get the following when running rails assets:precompile

And also, when deploying to Heroku, I get rubyDone in 4.85s. remote: /tmp/build_929254ebef3a89a9f40b4b26f007bde3/vendor/bundle/ruby/2.7.0/gems/sassc-2.3.0/lib/sassc/engine.rb:43: [BUG] Segmentation fault at 0x0000000000000000 remote: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux] -- Control frame information ----------------------------------------------- remote: c:0059 p:---- s:0449 e:000448 CFUNC :compile_data_context remote: c:0058 p:0314 s:0444 e:000443 METHOD /tmp/build_c5dc2802730effed8a887745a1195bb5/vendor/bundle/ruby/2.7.0/gems/sassc-2.3.0/lib/sassc/engine.rb:43 along with Aborted. remote: !

I don't get any other errors, so I think it's merely related to that compilation thing. I tried upgrading & downgrading the version of the gem but still can't get it through. I've been having this problem a while ago now and it had been sort of random, it wouldn't show up always, but recently, I get it almost every time I make a CSS change.

Can anybody help me out here? Thanks a lot in advance.

I believe I'm seeing the same thing while running tests on CircleCI. My test suite runs fine until it hits my integration tests which compile assets.

I've tried with these combos: ruby 2.6.6 & sassc 2.4.0 ruby 2.6.6 & sassc 2.3.0

Test output:

I saw something very similar after upgrading an older app to Sprockets 4, which introduced concurrent asset compilation. I'm guessing that something within sassc-ruby or libsass isn't thread-safe.

The problem goes away (for me) with Sprockets.export_concurrent = false in an initializer.

Yes, that's same as doing

config.assets.configure do |env|
    env.export_concurrent = false
end

in the application.rb, but not always works.

murtra commented 3 years ago

I'm having the same crash in development mode for an app that was recently upgraded to Sprockets 4 (Ruby 2.6.6, Rails 6.0.3). It's a random thing but happens very often.

Disabling concurrent asset compilation fixed the issue for me.

rlgreen91 commented 3 years ago

I'm seeing the same issues in our app, which uses Ruby 2.6.6 and Rails 5.0.7. The gem is at the most recent version, 2.4.0. This also occurred after an update to Sprockets 4.

The recommended solution of disabling concurrent asset compilation does not work when running our test suite locally.

bhserna commented 3 years ago

I was having a similar problem to @rlgreen91, my tests were also failing... And I found that the problem was in my code...

I was @importing a file from a dependency that I was just removed. After I removed the @import the segmentation fault was gone... It was not the best error message jeje, but the error was in my code.

... So if you are reading this thread, because you have a similar error, maybe your problem could also be a bad @import.

@bhserna your commented fixed my problem! Thhank you!

mvz commented 3 years ago

I have created an example app that reproduces this problem: https://github.com/mvz/example-app-sprockets-crash

stevenwilliamson commented 3 years ago

We are seeing the same problem segfault in the compile_data_context function. It is intermittent and we do not hit it every build but we tend to see the issue in CI when tests are running and Rails is compiling assets on the fly.

It does not look like there has been a commit to this repo for over a year, is this gem still active gem, is it deprecated, is it in maintenance, EOL?

It's not clear from looking at the Git repo if this is an active project or not, should we be using something else etc ?

epugh commented 3 years ago

@stevenwilliamson I am sympathetic!

I've been trying to figure out how to reduce the number of dependencies that I use in Rails, and this is an example of why... I'm maintaining an app that is 8 years old now, and it's a reminder that while my app may not change, the architectures under it are constantly evolving...

MarkerDave commented 3 years ago

We get the same error using Ruby 2.5.8 or 2.7.2 with rails 5.0.7.2, Sassc 2.4.0 and Sprockets 4.0. Setting export_concurrent = false does not fix the problem for us.

For any one still got this issue I've downgrade Sprocket gem to 3.7.2

gem 'sprockets', '3.7.2'

Then it's work. Please check more detail from https://github.com/rails/sprockets/issues/633

estebanz01 commented 2 years ago

Just adding another comment saying that disabling the concurrent mode fixes the issue for me. Basically, I did this:

Sprockets.export_concurrent = false if Rails.env.test?

So I can run the tests in my CI job.

uasi commented 2 years ago

I had the same issue on Intel Mac using Ruby 2.7.4, Rails 5.0.7.1, Sprockets 3.7.1, sassc 2.0.1, ffi 1.14.2, and libffi 3.4.2.

For me, only updating ffi gem to 1.15.4 fixed the issue. It seems the issue was triggered by a subtle incompatibility among libffi, ffi gem, and sassc native ext.

mfittko commented 2 years ago

For us the problem could be identified as iterating through a non thread-safe array in the manifest.json.erb file that is part of our asset pipeline, so maybe that helps some of you. We solved it by wrapping the array in Concurrent::Array.new. Might also work for a Concurrent::Hash.new, so check if you're having a loop within an erb file that is part of your pipeline.

jussihirvi commented 2 years ago

I use sass-rails, but stumbled on the same issue after upgrading ruby from 2.7.2 to 2.7.5, using rails 6.0.4.6 and sass-rails 6.0.0. Deleting everything from the assets folder (except config/manifest.js) did not help.

The problem vanished after I downgraded sass-rails to the newest 5.x version (5.1.0). I also had to downgrade sprockets from 4.0.3 to 3.7.2, because sass-rails 5.1.0 requires sprockets version <4.

kyrylo commented 2 years ago

@jussihirvi thank you! That helped me as well. I am tremendously grateful for your solution.

thisismydesign commented 1 year ago

I got this on sassc-2.4.0 and ruby-2.7.0

krzyczak commented 1 year ago

I just got the same issue with ruby 3.2 and rails 7.0.1 (Old macOS 13.10 - not sure if that's important).

I can confirm that adding Sprockets.export_concurrent = false solved the issue.

stanhu commented 8 months ago

I think we can close this issue because this is an issue with Sprockets, not with sassc-ruby.

I can reproduce the crash with Sprockets v3.7.2 and confirmed that it was indeed a thread-safety issue that has now been fixed in Sprockets v4.2.0 via https://github.com/rails/sprockets/pull/759. Those of you having trouble might want to upgrade to v4.2.1. I'm not sure if Sprockets.export_concurrent is still needed, but it might be.

In GitLab, we use Sidekiq to run background jobs to send notification e-mails. I can easily reproduce a seg fault by:

Clear the Sprockets cache: rm -rf tmp/cache/assets/sprockets/v3.0.
Run many instances of the job at the same time. In the Rails console, I scheduled the same job:

20.times { NewIssueWorker.perform_async(1, 1) }

I believe this was happening:

When multiple Sidekiq jobs attempt to render SCSS in notification e-mails, Sprockets invokes SassC::Rails::SassTemplate.call on a singleton object via processor_utils.rb.
Sprockets::Utils.module_include was previously not thread-safe, so the SASS functions list passed to libsass would be corrupted by one thread.
When libasss attempted to look up a SASS function, it would hit a seg fault if the function it needed wasn't in the list.

The following contains the Ruby and C backtrace:

I have tried to set the export_concurrent and try to not loading the rails app when doing precompile but without any success.

cesc1989 commented 3 months ago

As @stanhu suggested, I upgraded Sprockets gem to v4.2.1 and got it fix for me.

My setup:

Rails 7.0.4
Ruby 3.0.2
sass-rails 6.0.0

sass / sassc-ruby
