travis-ci timeouts when using `--coverage`? #88

Open abathur opened 6 years ago

abathur commented 6 years ago

I'm not sure if I've stumbled into a real issue, or just fallen into a documentation hole.

I had a bear of a time getting travis-ci set up this time. When I use run_tests --coverage, I get a timeout waiting for ST3 to respond. When I use run_tests without coverage, they run fine. The raw logs for both runs show the bootstrap installing sublime-coverage:

...
Running command: bootstrap 
copy the package to sublime package directory

download sublime-coverage tag: 1.0.0
bdda8348acf163fbb2c7e276d7d5415c2d0fa4bb

installing sublime text 3
...

Here's an example of the time-out/coverage run:

[0K$ sh travis.sh run_tests --coverage
Running command: run_tests --coverage
Schedule:
  output: /home/travis/.config/sublime-text-3/Packages/User/UnitTesting/Constellation/result
  syntax_test: False
  color_scheme_test: False
  coverage: True
  package: Constellation
Wait for Sublime Text response
.Xlib:  extension "RANDR" missing on display ":99.0".
............................................................Timeout: Sublime Text is not responding

Here's an example of one succeeding without:

[0K$ sh travis.sh run_tests
Running command: run_tests 
Schedule:
  output: /home/travis/.config/sublime-text-3/Packages/User/UnitTesting/Constellation/result

Cloning your package and running UnitTesting reveals that there is an error in the source code

With run_tests --coverage, UnitTesting would first reload the package first. The error may explain why UnitTesting is not responding. Also, you are using DeferrableTestCase but deferred is not set to true.

@randy3k Not running master, or my output would show the same.

I'd already wiped the debug branch I was working on, but I've re-produced the issue for you:

Broken/coverage: https://travis-ci.org/abathur/constellation/jobs/364712602 Working/no-coverage: https://travis-ci.org/abathur/constellation/jobs/364710289

abathur commented 6 years ago

@randy3k I saw that you were able to reproduce this CI failure on a fork yesterday. I also noticed that you've bumped versions, so ran the failing build again to see. It still breaks, but the output is a little different, so I thought I'd update you in case it saves a any work:

Maybe Sublime Text is not responding or the tests outputis being written to the wrong file.

Done. Your build exited with 1.

@randy3k I figured this out today. I'm tempted to close because this is mostly my fault, but I'll see what you think since it was a little tricky.

I'm not quite certain from here why the "timeout" messages on travis-ci. I suspect the above errors are just eating critical output and leaving it puzzled.

I'm fine with closing this unless you have some ideas about how one platform or the other could detect and message more clearly in this case.

randy3k commented 6 years ago

how about using yield form https://docs.python.org/3/whatsnew/3.3.html#pep-380?

abathur commented 6 years ago

I've got my tests working already; I needed to split methods up along similar lines for entirely different reasons, which is how I noticed what was going on.

But yes, the test method could have properly handled yield in a sub-call if I had been paying enough attention. :)

abathur commented 6 years ago

Though, I did get this other response (https://github.com/emanuelen5/Word-highlighter/commit/1fe8c0eccc22a78569a7d509e4d3f1ae0a71b2aa#commitcomment-30289483) from @emanuelen5; it sounds like his case was a simple syntax error. Maybe there's just a broader problem with the coverage script swallowing other messages (perhaps if they don't fit some format?)

randy3k commented 6 years ago

A syntax error like that is always fatal. This is the reason for the timeout.

randy3k commented 6 years ago

Wait, I may have misunderstood the issue, the error was from the test suite....there may be something fishy there.
