Assignee set to ko1 (Koichi Sasada) Status changed from Open to Assigned ---------------------------------------- Bug #15885: Duplicated `:raise` tracepoint event when exception inside `load` call happens https://bugs.ruby-lang.org/issues/15885#change-80170 * Author: deivid (David Rodr�guez) * Status: Assigned * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Target version: * ruby -v: * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- Hi! A long time ago, [this ruby-core change](https://github.com/ruby/ruby/commit/1998039ea4f867583d7e37ce200a88490707c330) broke a test in byebug related to post-mortem debugging. See https://github.com/deivid-rodriguez/byebug/issues/165. The problem is that after the mentioned commit, the TracePoint API raises two `:trace` events when an exception happens during a `load` call. As a result, byebug ends up using the second `:raise` event, and that means post-mortem debugging leaves the user in an incorrect place. I managed to workaround the issue inside byebug with https://github.com/deivid-rodriguez/byebug/pull/562, but I thought it would be worth mentioning here since it seems like incorrect behavior to me. For what it's worth, reverting the referenced commit fixes the issue. I attach a patch doing that together with a test. ---Files-------------------------------- 0001-Single-raise-tracepoint-event-when-exception-inside-.patch (4.44 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
