* `Socket.tcp` and `TCPSocket.new` raises `IO::TiemoutError` with user specified timeout
In https://github.com/ruby/ruby/pull/11880, `rsock_connect()` was changed to raise `IO::TimeoutError` when a user-specified timeout occurs.
However, when `TCPSocket.new` attempts to connect to multiple destinations, it does not use `rsock_connect()`, and instead raises `Errno::ETIMEDOUT` on timeout.
As a result, the exception class raised on timeout could differ depending on whether there were multiple destinations or not.
To align this behavior with the implementation of `rsock_connect()`, this change makes `TCPSocket.new` raise `IO::TimeoutError` when a user-specified timeout occurs.
Similarly, `Socket.tcp` is updated to raise `IO::TimeoutError` when a timeout occurs within the method.
(Note that the existing behavior of `Addrinfo#connect_internal`, which Socket.tcp depends on internally and which raises `Errno::ETIMEDOUT` on timeout, is not changed.)
* [ruby/net-http] Raise `Net::OpenTimeout` when `TCPSocket.open` raises `IO::TimeoutError`.
With the changes in https://github.com/ruby/ruby/pull/15602, `TCPSocket.open` now raises `IO::TimeoutError` when a user-specified timeout occurs.
This change updates #connect to handle this case accordingly.

The try-open_timeout-then-fallback-to-timeout introduced in
https://github.com/ruby/net-http/commit/1903cedd8cd0 works well, but when it errors
due to any reason in Rubies which do not support `open_timeout`, it
spits the rescued ArgumentError that is unrelated to user code and not
actionable.

This patch suppresses the ArgumentError by moving the retry out of the
rescue clause.
https://github.com/ruby/net-http/commit/86232d62f5
For open_timeout support detection, the previous implementation relied
on an ArgumentError being raised and then rescued. In Ruby, rescue is a
rather expensive operation and should be avoided when possible.
This patch reduces the number of begin-rescues by remembering if the
TCPSocket implementation supports open_timeout.
https://github.com/ruby/net-http/commit/06d982f3a1
This patch replaces the implementation of #open_timeout from Timeout.timeout from the builtin timeout in TCPSocket.open, which was introduced in Ruby 3.5 (https://bugs.ruby-lang.org/issues/21347).
The builtin timeout in TCPSocket.open is better in several ways than Timeout.timeout. It does not rely on a separate Ruby Thread for monitoring Timeout (which is what the timeout library internally does).
Furthermore, it is compatible with Ractors, as opposed to Timeout.timeout (it internally uses Thread::Mutex which can not be used in non-main Ractors).
This change allows the following code to work.
require 'net/http'
Ractor.new {
uri = URI('http://example.com/')
http = Net::HTTP.new(uri.host, uri.port)
http.open_timeout = 1
http.get(uri.path)
}.value
In Ruby <3.5 environments where `TCPSocket.open` does not have the `open_timeout` option, I have kept the behavior unchanged. net/http will use `Timeout.timeout { TCPSocket.open }`.
https://github.com/ruby/net-http/commit/728eb8fc42
Freeze `Net::HTTP::SSL_IVNAMES`, `Net::HTTPResponse::CODE_CLASS_TO_OBJ`
and `Net::HTTPResponse::CODE_TO_OBJ` to improve Ractor compatibility.
This change allows the following code to work:
Ractor.new {
uri = URI.parse('http://example.com')
http = Net::HTTP.new(uri.host, uri.port)
http.open_timeout = nil
http.read_timeout = nil
http.get('/index.html')
}
