Bug #1540

read on win32 now defaults to blocking

Added by rogerdpack (Roger Pack) about 13 years ago. Updated about 11 years ago.

Status:
Third Party's Issue
Priority:
Normal
Target version:
ruby -v:
TRUNK
Backport:
[ruby-core:23638]

Description

=begin
Currently the win32.{c,h} files override calls to "read" in the code with windows style read calls.
The goal being to give read the same semantics on both linux and windows, for c ruby code.

With 1.8.6 the calls to read on linux+windows defaulted to non blocking.
Now (perhaps inadvertently) with 1.9, on linux they default to non blocking, and on windows blocking. This breaks libraries that do their own "readability" checks then calls to read (like rev, eventmachine).
The request is to go to non blocking for linux+windows for 1.9, unless this is an expected change.
Thanks!

=begin
Appears that with 1.9 + windows you must use fcntl [instead of direct ioctlsocket] so that ruby adds the socket to its internal list of non blocking descriptors. EventMachine wasn't doing that [since it wasn't necessary with 1.8] but it seems to be working now.
You can probably close this.
Thanks to Bill Kelly for figuring it out.
