TestAttachDenied - timing out

Hi all,

I’ve been running the test suite for quite some time on the Linux side. I pretty consistently see this test case file:


time out on my Linux setup (prior to any of my test runner changes). I’m noticing it is now showing up on the Google Linux buildbot (here - build 6802).

I just wanted to throw out there that this isn’t a new phenomenon on my end (Ubuntu 14.04 x86_64 built with clang 3.6 and tested with inferiors built with clang 3.6).

That said, I’m going to disable the test and look into why it is timing out so our poor Google test runner doesn’t take forever to go through the tests.

I’ll file a ticket and look into it.

I disabled it on Linux with this:

svn commit
Sending functionalities/process_attach/attach_denied/TestAttachDenied.py
Transmitting file data .
Committed revision 248846.

I killed build 6803 on the Linux buildbot since the tests would have taken 25+ minutes to run through the timeout on the theory that getting the results net faster would be better. 6804+ should have the test disabled that was timing out.

Test used to be flaky from time to time but in http://lab.llvm.org:8011/builders/lldb-x86_64-ubuntu-14.04-cmake/builds/6802 it failed consistently for all configurations - that’s pretty suspicious.
Test inferior writes some output to stdout and stderr - I don’t have a lot of context about http://reviews.llvm.org/D13124 but as I can see all standard streams are set to subprocess.PIPE, as a guess
maybe inferior tries to write sth in stdout/stderr but nobody is reading this data on python side.

Thanks, Oleksiy!
