Bug #10190
Updated by nobu (Nobuyoshi Nakada) over 9 years ago
I found a segmentation fault when `Thread::Queue` is attached to a dRuby server as a front object and `#push` is called from a dRuby client. Here are programs, a procedure and logs. ## server.rb ~~~ruby ~~~ require 'drb/drb' require 'thread' q = Queue.new DRb.start_service('druby://localhost:12345', q) DRb.thread.join ~~~ ## client.rb ~~~ruby ~~~ require 'drb/drb' require 'thread' DRb.start_service q = DRbObject.new_with_uri('druby://localhost:12345') q.push 1 ~~~ ## procedure ~~~ $ ruby server.rb # in another terminal $ ruby client.rb ~~~ ## server.rb log ~~~ /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:562: [BUG] Segmentation fault at 0x00000000000018 ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux] ~~~ ## client.rb log ~~~ /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:575:in `load': connection closed (DRb::DRbConnError) from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:637:in `recv_reply' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:936:in `recv_reply' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1222:in `send_message' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1110:in `block (2 levels) in method_missing' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1197:in `open' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1109:in `block in method_missing' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1128:in `with_friend' from /home/itiut/.linuxbrew/var/rbenv/versions/2.1.2/lib/ruby/2.1.0/drb/drb.rb:1108:in `method_missing' from client.rb:5:in `<main>' ~~~ I tried executing the procedure many times but the server's log contained detailed information only once or twice. Fortunately I found it in a terminal scrollback buffer, so I attach it.
