Bug #15886: return in rescue block breaks Timeout.timeout
https://bugs.ruby-lang.org/issues/15886#change-78349
* Author: moio (Silvio Moioli)
* Status: Rejected
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
Passing `Timeout.timeout` a block with a rescue clause that contains a return statement prevents `Timeout::Error` to be raised as expected.
Reproducer:
``` ruby
require 'timeout'
begin
Timeout.timeout(1) do
begin
sleep 10
ensure
puts "ensure block executed"
## commenting line below restores expected behaviour
return true
end
end
rescue Timeout::Error => e
puts "EXPECTED BEHAVIOUR: timeout error rescued"
end
```
Expected output:
```
ensure block executed
EXPECTED BEHAVIOR: timeout error rescued
```
Actual output:
```
ensure block executed
```
