From: Greg.mpls@... Date: 2018-03-30T18:07:24+00:00 Subject: [ruby-core:86407] [Ruby trunk Bug#14642] Fiber make crash on Windows - webrick/httpproxy.rb ? Issue #14642 has been updated by MSP-Greg (Greg L). I did a vc14 build (`ruby 2.6.0dev (2018-03-31 trunk 63043) [x64-mswin64_140]`), it behaves the same as the MinGW build. Using the test `TestWEBrickHTTPProxy#test_proxy` in `test/webrick/test_httpproxy.rb`, when `HTTPProxyServer#perform_proxy_request` (`lib/webrick/httpproxy.rb`) is called link - https://github.com/ruby/ruby/blob/46b391ff731d66883082e6347d5fc4e54386d7bd/lib/webrick/httpproxy.rb#L298-L347. The code runs to line 334, the `Fiber.yield` statement, and stops, as in back to command prompt, with no indication of the problem. The fiber is first started by `req_fib.resume` on line 339. Thanks, Greg ---------------------------------------- Bug #14642: Fiber make crash on Windows - webrick/httpproxy.rb ? https://bugs.ruby-lang.org/issues/14642#change-71336 * Author: usa (Usaku NAKAMURA) * Status: Assigned * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Target version: * ruby -v: trunk r62966 * Backport: 2.3: DONTNEED, 2.4: DONTNEED, 2.5: DONTNEED ---------------------------------------- We found that r62966 causes crash on Windows. Of course, the patch seems to be no problem, so I guess that this code just happened to reveal a potential bug. FYI, AppVayor and mswinci both reported the crash, but they didn't show any details. Stable versions don't contain the patch, but will be backported later, maybe. -- https://bugs.ruby-lang.org/ Unsubscribe:
