I am using system-provided sonic-pi on Ubuntu 20.04. When stopping a loop, a thread terminates with exception:
#<Thread:0x000055f182e5a758 /usr/lib/sonic-pi/server/sonicpi/lib/sonicpi/runtime.rb:778 run> terminated with exception (report_on_exception is true):
/usr/lib/ruby/2.7.0/set.rb:328:in `each_key': ret: 2, hash modified during iteration (RuntimeError)
from /usr/lib/ruby/2.7.0/set.rb:328:in `each'
from /usr/lib/sonic-pi/server/sonicpi/lib/sonicpi/runtime.rb:409:in `__join_subthreads'
from /usr/lib/sonic-pi/server/sonicpi/lib/sonicpi/runtime.rb:782:in `block in __spider_eval'
This failure seems similar to one described here [1], which has been confirmed as a bug in Ruby [2]. The issue has received a one-line patch, which has been incorporated in Ruby v2.7.1.
[1] https://github.com/kpumuk/meta-tags/issues/209
[2] https://bugs.ruby-lang.org/issues/16503 |
[Impact]
Ruby code cannot iterate over hashes while the garbage collector is started.
This was fixed upstream here:
https://bugs.ruby-lang.org/issues/16503
https://github.com/ruby/ruby/commit/8e8841f6bf58031a1fe5b0dbacb5a1fb442102df
[Test Plan]
$ lxc launch ubuntu-daily:focal ruby27-hash-iteration
$ lxc shell ruby27-hash-iteration
# apt update && apt upgrade -y && apt install -y ruby
# cat <<EOF >bug.rb
h = {a:1, b:2, c:3, d:4, e:5, f:6, g:7, h:8}
h.each{|k,v| GC.start; h.delete(k)}
EOF
# ruby bug.rb
Traceback (most recent call last):
1: from bug.rb:2:in `<main>'
bug.rb:2:in `each': ret: 2, hash modified during iteration (RuntimeError)
The error above should not happen.
[Where problems could occur]
This is a one line fix which should be straightforward, but if something happens it would be related to the .each method since the modification is there. Any unexpected behavior in .each might be related to this change.
