Subject: retry / redo question


Hi,

i have a ruby script that does for 1 - n  folders a
cp_r of every folder to an existing cvs workspace
and afterwards the cvs operations 
update to determine if add is needed
add if needed 1-n times
commit

As the cvs CLI lacks a recursive parameter for
the update / add  commands, means when a new file
like subfolder/subfile.txt comes in 
the add command only recognizes subfolder, but the 
subfile.txt only after a 2nd add command

 i have to do =

1. updpipe=IO.popen("#{CVSEXE} -d #{CVSROOT} update")
     updpipe.readlines.each { |x| 
       updfiles<<'.'<<'/'<<x[2..-2]<<' ' }

to determine whether there are new files to be added

if updfiles != 0 i have to execute the cvs add command =

2.addpipe=IO.popen("#{CVSEXE} -d #{CVSROOT} add #{updfiles.to_s}")
   addpipe.readlines.each { |x| 
   addfiles<<'.'<<'/'<<x[2..-2]<<' ' }

this add command gives me other folders or files that are also to be
added, if there are more to be added, i.e subfolders/subfiles ...

so i have to do the cvs add in a loop until nothing more comes
back from that cvs add command. 

then i have to do a final commit =

3.system("#{CVSEXE}","-d","#{CVSROOT}","commit","-m","bla bla bla bla")


Now i'm looking for the best loop construct, i know
the addfiles array has to be cleared after every cvs add before
executing cvs add again

There is something like retry/redo i tried with retry after and before
the end of a while loop 

updfiles=Array.new
updpipe=IO.popen("#{CVSEXE} -d #{CVSROOT} update")
     updpipe.readlines.each { |x| 
       updfiles<<'.'<<'/'<<x[2..-2]<<' ' }

while updfiles.length > 0
	addfiles=Array.new
	addpipe=IO.popen("#{CVSEXE} -d #{CVSROOT} add #{updfiles.to_s}")
	addpipe.readlines.each { |x| 
	addfiles<<'.'<<'/'<<x[2..-2]<<' ' }	
updfiles.clear
addfiles.clear
	updpipe.readlines.each { |x| 
	updfiles<<'.'<<'/'<<x[2..-2]<<' ' }
end
*retry*

but got :

retry outside of rescue clause (LocalJumpError)


What's the right loop ?
Is there a solution without retry / redo ?
