Subject: [ruby-core:117330] [Ruby master Bug#20168] Process won't exit when Ractor.select waiting a Ractor
Date: Tue, 26 Mar 2024 15:02:24 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-107474.20240326150223.17767@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20168.20240109092943.17767@ruby-lang.org
Issue #20168 has been updated by over.rye@gmail.com (Masato Ohba).
I think I have encountered the same issue. I was able to reproduce the problem using a simpler code that results in a process hang when a Ractor, which internally raises an exception, is passed to `Ractor.select`.
Here is the minimal code snippet that demonstrates the issue:
```ruby
ruby -e "r = Ractor.new{1/0}; Ractor.select(*[r])"
```
Notably, when I built Ruby using the branch from https://github.com/ruby/ruby/pull/9492, the issue did not occur. It appears that the changes in this branch might contain a fix or alter the behavior to prevent the hang.

Bug #20168: Process won't exit when Ractor.select waiting a Ractor
https://bugs.ruby-lang.org/issues/20168#change-107474
* Author: shia (Sangyong Sim)
* Status: Open
* ruby -v: 3.3.0
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
## Reproduction code
```ruby
trap(:INT) do
puts "SIGINT"
exit
end
trap(:TERM) do
puts "SIGTERM"
exit
end
r = Ractor.new do
loop do
sleep 1
end
end
Ractor.select(r) # stucked.
# SIGINT/SIGTERM sent to Ruby process(confirmed by trap),
# but process won't exit.
```
## Expected behavior
Process killed successfully with exit code 0.
## Affected Ruby version
3.3.0
3.2.x works as expected.
