Subject: [ruby-core:94522] [Ruby master Bug#12702] DRb client fails when calling out-of-process remote method with a block
Date: Sat, 24 Aug 2019 03:21:19 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-80963.20190824032118.35b1b6e075878ba9@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-12702.20160824114621@ruby-lang.org
Issue #12702 has been updated by jeremyevans0 (Jeremy Evans).
Status changed from Open to Rejected
This is a bug in your code, you are not calling `DRb.start_service` in the client program. The client program needs a DRb server running in order to handle the sending-block-to-remote-method case. See the example in the "Client code" section of the `DRb` module rdoc.

Bug #12702: DRb client fails when calling out-of-process remote method with a block
https://bugs.ruby-lang.org/issues/12702#change-80963
* Author: djellemah (John Anderson)
* Status: Rejected
* Priority: Normal
* Assignee: seki (Masatoshi Seki)
* Target version:
* ruby -v: ruby 2.4.0dev (2016-08-24 trunk 55999) [x86_64-linux]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
See attached code for test case.
applies to ruby-2.3.1 and ruby-2.4.0dev (2016-08-24 trunk 55999)
The problem starts in DRbObject#method_missing where
the code following DRb.here? is used for the in-process case which works.
But the code in the block for
succ, result = self.class.with_friend(@uri) do
is used for the out-of-process case. Here, DrbMessage#send_request fails
because b is a Proc, and in DrbMessage#dump the call to make_proxy fails
because DRbObject.new(b) fails.
