I post a similar message to rails mailing list since I encountered
this problem during development of a rails application, but now the
problem is more ruby specific, so I decided to post here.
Basically, I have to implement a critical section like this to avoid
/* begin critical section /
filename = generate_filename
break unless File.exist?(filename)
/ end */
Somebody said I could open a file with exclusive lock, but I do not
know an atomic way. Could anyone help? Thanks alot!
