Setting TCPSocket timeout has no effect
---------------------------------------
Key: JRUBY-6098
URL: https://jira.codehaus.org/browse/JRUBY-6098
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.6RC1
Environment: # java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.2) (suse-4.3.1-i386)
OpenJDK Server VM (build 20.0-b11, mixed mode)
Reporter: Xuân Baldauf
For a TCPSocket socket,
{noformat}socket.setsockopt(Socket::SOL_SOCKET,TCPSocket::SO_RCVTIMEO,
1000){noformat}
has no effect, as
{noformat}
Timeout::timeout(1) do
socket.read
end
{noformat}
has no effect, as
{noformat}socket.to_channel.socket.setSoTimeout(1000){noformat}
has no effect.
Thus, there is no real means to prevent resource leaks or filedescriptor leaks
in a networked application where remote hosts may not respond (and thus not
properly close the connection) from time to time, as the app itself will read
indefinitely once it attempts to read.
