Subject: [ruby-core:113302] [Ruby master Bug#19609] net/http ignores open_timeout, read_timeout on Windows

Issue #19609 has been reported by inversion (Yura Babak).



----------------------------------------

Bug #19609: net/http ignores open_timeout, read_timeout on Windows

https://bugs.ruby-lang.org/issues/19609



* Author: inversion (Yura Babak)

* Status: Open

* Priority: Normal

* ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt]

* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

----------------------------------------

This small sample works fine on Linux (it takes 2 seconds to finish) but on Windows, it always fails with a timeout after some **magical 21 seconds**.



``` ruby

require 'net/http'



uri = URI 'http://1.2.3.4'

http = Net::HTTP::new(uri.host, uri.port)

http.open_timeout = 2

http.read_timeout = 2



time_start = Time.now

begin

	response = http.get uri

rescue Exception

	puts $!.inspect

end

time_total = Time.now - time_start



puts time_total

```





Strange that I have installed different versions and the results are not consistent:



**ruby 3.2.2** (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt]:

```

#<Net::OpenTimeout: Failed to open TCP connection to 1.2.3.4:80 (execution expired)>

21.0494375

```



**ruby 3.1.2p20** (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]:

2.0190419   # ��� works as expected

```



**ruby 3.0.1p64** (2021-04-05 revision 0fb782ee38) [x64-mingw32]:
