Bus Error with Unicorn 6.0 on OpenBSD/adJ 6.8 with Ruby 3.0

Bus Error with Unicorn 6.0 on OpenBSD/adJ 6.8 with Ruby 3.0

[vtamara]

Hi

Launching a rails application with Ruby 3, Unicorn 6 on OpenBSD/adJ 6.8, 
I'm
experiencing a lot of "Bus Error" and "Segmentation Faults" during 
aproximately half hour. Around the first 10 minutes the application is 
not accessible from a browser. After it is possible to use the 
application and after half hour it runs withouth errors.  Pasting below 
what appears in the log file after launching the application at 9:29AM 
and trying to use it at 9:30AM:

It failed 175 times between 9:30 and 9:56 (around 7 times per minute).

I'm pasting below details of the first errors (the others are very 
similar):

+Cc: Jeremy Evans, who is more familiar with OpenBSD and Ruby 3.0 than I
cf. https://yhbt.net/unicorn-public/6acb1c84c7392d7b4a64572b20498549@pasosdeJesus.org/

vtamara: did previous versions of Ruby, unicorn, or OpenBSD work
for your app?

Is preload_app in use?  If so, does the problem manifest without
preload_app?

Are you using Ractor or any other new/experimental stuff
in Ruby?

Can you reproduce the problem with a simple "hello world"-style app?

That's a strange one, I wonder if OpenBSD getenv(3) has some
restrictions or other odd behaviors with it?

Do you have any code/dependencies which are calling "ENV#[]=" in
Ruby; setenv()/putenv() in C, or modifying "environ" directly
in C?

Especially in sub-threads/Ractors at startup...

Any other .so extensions?  C extensions can do any number of

I'll be happy to look into this if a minimal self-contained reproducible
example is posted.  Personally, I run my Ruby apps on OpenBSD amd64 with
Unicorn, and haven't seen similar errors.  However, I don't use
preload_app and use fairly minimal dependencies.

Thanks,
Jeremy

Hi

Thank you very much for the reply and the interest in helping.

The application was working withouth issue on OpenBSD/adJ amd64 6.7, 
ruby 2.7 and unicorn 6.0.  So there is something in conflict betweeen 
Unicorn 6.0 with OpenBSD/adJ 6.8 and ruby 3.0.

I don't have a hello world example at hand, but some projects that 
present this problem when I run them on OpenBSD/adJ amd64 6.8, nginx 
1.18.0, node 12.16.1, PostgreSQL 13.2, Ruby 3.0, Rails 6.1 and Unicorn 
6.0 are:

https://github.com/pasosdeJesus/cor1440
https://github.com/pasosdeJesus/cor1440_pdJ
https://github.com/pasosdeJesus/sivel2
https://github.com/pasosdeJesus/si_anzorc
https://github.com/pasosdeJesus/si_asom
https://github.com/pasosdeJesus/si_codacop
https://github.com/pasosdeJesus/sivel2_mujeresindigenas/

The simplest of them is https://github.com/pasosdeJesus/cor1440, althoug 
it requires:
* PostgreSQL
* nginx
* nodejs
* yarn. I install it with: doas pkg_add bash; ftp -o- 
https://yarnpkg.com/install.sh | bash
* A directory /var/www/bundler/ruby/3.0 where I install the gems with 
the permissions of a user (not root) that runs the application, and 
better running:
   bundle config path /var/www/bundler/.
* unicorn installed globally with:
   doas gem install unicorn
   doas ln -s /usr/local/bin/unicorn_rails30 /usr/local/bin/unicorn

To create the PostgreSQL user (in the following example sipdes) and a 
database for the production environment  (in the following example 
cor1440gen_pro):

   doas su - _postgresql
   createuser -h /var/www/var/run/postgresql/ -U postgres -s sipdes
   createdb -h /var/www/var/run/postgresql/ -U postgres -O sipdes 
cor1440gen_pro
   psql -h /var/www/var/run/postgresql/ -U postgres
   postgres=# alter user sipdes with password 'xyz';
   postgres=# \q
   exit

With nginx suppossng I will run the application in localhost over SSL, 
what I do is to choose an unused port (let's say 2009) and add to the 
/etc/nginx/nginx.conf configuration in its http block:

  upstream unicorncor1440 {
	  server 127.0.0.1:2009 fail_timeout=0;
   }

I also add a server block inside the http block with:

   server {
       listen 443 ssl;
       ssl_certificate /etc/ssl/server.crt;
       ssl_certificate_key /etc/ssl/private/server.key;
       root /var/www/htdocs/cor1440/;
       server_name 127.0.0.1;
       error_log logs/cor1440.rror.log;

       location /cor1440 {
         try_files $uri @unicorncor1440;
       }

       location @unicorncor1440 {
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto $scheme;
         proxy_set_header Host $http_host;
         proxy_redirect off;
         proxy_pass http://unicorncor1440;
         error_page 500 502 503 504 /500.html;
         keepalive_timeout 10;
       }

       location ^~ /cor1440/assets/ {
         gzip_static on;
         expires max;
         add_header Cache-Control public;
         root /var/www/htdocs/cor1440/public/;
       }

       location ^~ /cor1440/images/ {
         gzip_static on;
         expires max;
         add_header Cache-Control public;
         root /var/www/htdocs/cor1440/public/;
       }

       location ^~ /cor1440/packs/ {
         gzip_static on;
         add_header Cache-Control public;
         root /var/www/htdocs/cor1440/public/;
       }
     }

And restarted nginx:

   doas rcctl restart nginx

Then to configure:

   cd /tmp
   git clone git@github.com:pasosdeJesus/cor1440
   doas mv cor1440 /var/www/htdocs/
   doas chown -R $USER:$USER /var/www/htdocs/cor1440
   cd /var/www/htdocs/cor1440
   mkdir .bundle
   echo '---' > .bundle/config
   echo 'BUNDLE_PATH: "/var/www/bundler"' >> .bundle/config
   echo 'BUNDLE_DISABLE_SHARED_GEMS: "true"' >> .bundle/config
   bundle

Here some gems will require installing with special permissions for 
example:

   doas gem install --install-dir /var/www/bundler/ruby/3.0 unicorn

Other gems that will require this kind of installation will be:
   racc nio4r websocket-driver bcrypt bindex msgpack ffi redcarpet kgio 
libxml-ruby pg
   nokogiri bootsnap puma sassc

Once bundle runs completely:

   cp .env.plantilla .env
   vi .env

There I set the variables:
* BD_USUARIO with the database user,
* BD_CLAVE with the password
* BD_PRO with the name of the production database
* CONFIG_HOSTS=127.0.0.1
* DIRAP with the path to the application
* RAILS_ENV=production
* PUERTOUNICORN with the port I choosed and set in nginx.conf
* USUARIO_AP with the operating system user who will run the application

Prepare credentials and database:

   bin/rails credentials:edit
   RAILS_ENV=production bin/rails credentials:edit
   bin/railsp db:setup  db:migrate sip:indices

Precompile assets:

   CXX=c++ yarn
   doas ln -s /usr/local/bin/node /tmp  # To overcome bug of node with 
rails on OpenBSD
   bin/railsp assets:precompile

Run the application with:
   SECRET_KEY_BASE=cf46 DIRAP=/var/www/htdocs/cor1440/ bin/u.sh

Trying to see the application running with a browser in 
https://127.0.0.1/cor1440 will produce the errors described in 
log/unicorn.log.

Blessings. Thank you.

Unfortunately, given the required amount of setup, I don't think I'll
have time to look into this.  The best way to debug this is to start
removing code/dependencies piece by piece until the problem goes away.
Once the problem goes away, add that code back, and make sure it fails
again, then start removing other code/dependencies.  Repeat this process
until you have the most minimal example, where removing any additional
code/dependencies will stop the code from failing.

Sorry,
Jeremy

The above is exactly what I would do, too.

I would also try to correlate the time of Bus Errors with logs
of when + which requests are failing, and try replaying only
those requests to narrow things down.

Also, do you have core dumps enabled?  Enable those
("ulimit -c unlimited" in sh), and run gdb on them as you get
them.  The .gdbinit in the source tree of the Ruby version
you're using is helpful not just for Ruby itself, but
also C extensions, too.  I'm no a gdb expert, but it's
well-documented and has built-in help.

Bus Error with Unicorn 6.0 on OpenBSD-current (6.9) with Ruby 3.0 in minimal rails application

[vtamara]

Good evening

I found that the problem happens also:

1. In OpenBSD-current (what will be 6.9 soon) --for that reason I copy 
to ports-openbsd
2. With what I consider the minimal rails application,  started with the 
flag --minimal, running with sqlite, i.e:

rails new --minimal ap61

The configuration of gems in /var/www/bundler and the configuration of 
nginx is as I explained in the previous email  
https://yhbt.net/unicorn-public/20210404200358.GA32719@dcvr/T/#mcf469c2eb443db6c9e4fee55afa3b252606c27f2 
but  changing cor1440 with ap61.
