Backport #3853: Multiple IO problems when threading is used

• Status: Closed
• Assignee: -

=begin

• File.read(path) sometimes returns empty string although file is not empty
• File.read(path, File.size(path)) somtimes returns nil although file is not empty

It seems as if the file reached eof. This happens only when threading is used. There seems to be some kind of race condition.

Ruby version is 1.8.7-p302 (on x86_64-linux and x86-linux).
This problem doesn't exist on 1.9 (tested with 1.9.1p429).

This can be a real bug but we cannot check it without a reproducible code snippet.

=begin
Well, until now I couldn't reproduce it in a simple snippet but it happens quite often in my application. I hoped that someone might have observed something similar. I try to create a snippet.
