Change subject: [subprocess] test to repro deadlock in Subproces::Run() ...................................................................... Patch Set 4: (1 comment) Thank you for review! http://gerrit.cloudera.org:8080/#/c/12740/3/src/kudu/util/subprocess-test.cc File src/kudu/util/subprocess-test.cc: http://gerrit.cloudera.org:8080/#/c/12740/3/src/kudu/util/subprocess-test.cc@375 PS3, Line 375: size_t msg_id = 0; > why not have a while (!done) with a atomic<bool> done set by the main threa I wanted to clearly see if the sub-process deadlocks and capture the stack if that happens. I added alarm() a bit later. :) If targeting for successful cases only it's a good idea to introduce the atomic variable, thanks.
