Subject: [ruby-core:65108] [ruby-trunk - Bug #9356] TCPSocket.new does not	seem to handle INTR

Issue #9356 has been updated by Usaku NAKAMURA.


Perhaps, we should write a test that actually causes EINTR during `connect`.

But, when I committed r7931, there was a failure of an existing test, I guess.
At the moment, such failure has not been observed.
So, I think that there is not a big portability problem in this patch.

Thank you, Eric.

Bug #9356: TCPSocket.new does not seem to handle INTR

* Author: Charlie Somerville

* Backport: 1.9.3: UNKNOWN, 2.0.0: REQUIRED, 2.1: REQUIRED
----------------------------------------
TCPSocket.new does not seem to handle EINTR properly.

In the attached test script, I try to open a TCP connection to my server and make an HTTP request while a background thread continually sends a signal to the process.

This causes the #write call to fail with:

x.rb:13:in `write': Socket is not connected (Errno::ENOTCONN)
	from x.rb:13:in `<main>'

This also appears to affect 2.0.0. 1.9.3 is unaffected.
