How to use "retry" into two deep begin/rescue/end ?

[Iñaki Baz Castillo]

Hi, in the code below I want "retry/break/XXXXX" (undefined) in SECOND BEGI=
N=20
to go back to FIRST BEGIN when "raise" instead of SECOND BEGIN but it goes =
to=20
SECOND BEGIN.

I think it's the expected behaviour but maybe there is a way to get what I=
=20
want, is it possible?


=2D-----------------------------------------------------------
class MyTcpServer < GServer

def serve(io)

loop do
begin # FIRST BEGIN
puts "welcome"
...
...
begin # SECOND BEGIN
raise
rescue
puts "ERROR"
retry/break/return/XXXXX # Restart from FIRST BEGIN (doesn't work)
end
...
...
rescue
$stderr.print "serve(io) ERROR: " + $!
end
end # loop do

end # def serve(io)
=2D-----------------------------------------------------------


Thanks a lot.

Can you combine the two?

class MyTcpServer < GServer

def serve(io)

loop do
begin # FIRST BEGIN
puts "welcome"
...
...
raise
...
...
rescue NameError # or whatever class of error you want to catch
$stderr.print "serve(io) ERROR: " + $!

rescue # most other stuff

=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 rescue # most other stuff

But what I want is going back to the previous/parent loop.

C:\family\ruby>cat test.rb
loop do
begin # FIRST BEGIN
puts "first welcome"

begin # SECOND BEGIN
raise "triggered ERROR in second begin"
rescue =3D>e
puts "rescuing error: "+e.message
puts "retrying to first welcome.."
sleep 1 # put this to slow down
next # this goes back to next loop
end
rescue
puts "Error in first welcome"
end
puts "this is never executed in this example "
end

C:\family\ruby>ruby test.rb
first welcome
rescuing error: triggered ERROR in second begin
retrying to first welcome..
first welcome

Yeah !! thanks a lot, I was looking for it but I've not found that "next"=20
command anywhere. Thanks
