tests: Re-enable RPC tests for Windows #8227

laanwj · 2016-06-20T08:14:36Z

Try RPC tests in Travis windows builds.

Just a test, don't merge this yet.

laanwj · 2016-06-20T09:07:36Z

p2p-versionbits-warning.py fails while shutting down the nodes. ~~This seems to be a randomly occuring issue, not related to the specific test.~~

~~It looks like this isn't working, or that the http shutdown is taking too long and thus quitting without returning anything: https://github.com/bitcoin/bitcoin/blob/master/src/httpserver.cpp#L485~~

~~Conclusion: not safe to enable P2P tests for windows yet in travis. They tend to work, but this shutdown issue would introduce too many false positives.~~ (this conclusion was wrong, see below)

maflcko · 2016-06-20T09:11:09Z

Isn't it also failing the assert(self.vb_pattern.match(alert_text))?

laanwj · 2016-06-20T09:12:53Z

Ok that's one confusing error, yes that one's failing too. That seems specific to this test.
Let's see if it is repeatable.

laanwj · 2016-06-20T10:01:30Z

Okay at least the error is consistent. I retriggered Travis and it happens again, same place, same error.

And the 32-bit windows build fails due to the same reason.

Edit: I can also reproduce it locally in a depends build.

laanwj · 2016-06-20T10:43:56Z

I've pushed a commit that should get past this problem.

maflcko · 2016-06-20T10:51:14Z

qa/rpc-tests/p2p-versionbits-warning.py

Nit: I think it is good practice to put those in the header.

Yeah, unless there is a specific reason for late binding (there doesn't seem to be here)

Feel free to fix the nit in this pull.

maflcko · 2016-06-20T10:51:16Z

Thanks.

If this passes, make sure to remove any remaining -win hacks from the script.

laanwj · 2016-06-20T11:21:21Z

It passed! Reorganized the commits and removed any mention of -win in rpc-tests.py. I may be looking past it, but I didn't find any use of that option anywhere.

utACK 39d28c6

laanwj · 2016-06-20T12:39:02Z

Looks like there are timeout issues, run times for the windows tests are on the limit of what travis allows

maflcko · 2016-06-20T15:04:40Z

I've added a commit to fa58f94 which should improve that, but I think after enabling qt builds again, we are again at the limit...

laanwj · 2016-06-21T08:31:00Z

Re-triggered this after merging #8216, let's see if this is more reliable.

`p2p-versionbits-warning.py` uses an alertnotify that writes to a file using `echo`. Windows `echo` doesn't strip quotes. So accept the alert message to be surrounded by quotes in the regular expression.

Re-enable the RPC tests for Windows. The issues preventing running the RPC tests on windows have been resolved by upgrading to Trusty. Remove the `-win` option from `rpc-tests.py`.

maflcko · 2016-06-21T11:09:28Z

There was a timeout in

  File "qa/pull-tester/rpc-tests.py", line 254, in get_next

    (stdout, stderr) = proc.communicate(timeout=3)

but not due to the travis limit of 50 minutes.

maflcko · 2016-06-21T11:13:02Z

This should not happen: It can either mean there is a zombie bitcoind running which can not be stopped (a bug we should fix) or the windows tests are running generally really slow. Bumping the timeout to 5 secs or more should fix it then.

laanwj · 2016-06-21T11:26:12Z

What is the three-second timeout waiting for?

maflcko · 2016-06-21T11:31:23Z

If it has to wait, there is most likely a bug elsewhere in the framework. Ideally there should be no timeout set, but it has to be set to anything to change the default: https://docs.python.org/3/library/subprocess.html#subprocess.Popen.communicate.

maflcko · 2016-06-21T11:35:26Z

Unfortunately running the tests in parallel will hide what actually happened until the stderr and stdout are retrieved.

I could come up with a -legacy arg to run the test sequentially with real time stdout like was done previously, for debugging purposes.

maflcko · 2016-07-05T15:02:12Z

@laanwj I ran this locally to see what is the cause of the intermittent fails, but I couldn't figure it out. It has nothing to do with the timeout=3. (You could set it to less without any issues)

I'd suggest you cherry-pick/pull fa9d398 and we just merge it. Someone can figure out later why parallel test don't work fine with wine/win.

laanwj · 2016-07-11T11:08:14Z

@MarcoFalke Thanks - cherry-picked your commit, let's see what travis does now.

laanwj · 2016-07-11T12:50:35Z

Ugh win32 build https://travis-ci.org/bitcoin/bitcoin/jobs/143858179: The job exceeded the maximum time limit for jobs, and has been terminated.

maflcko · 2016-08-08T09:12:19Z

The job exceeded the maximum time limit for jobs, and has been terminated.

Dropping the java block tester at the same time could improve the run time.

laanwj · 2016-08-13T13:54:36Z

Good point, that is due to be disabled now: #4545 (comment)

maflcko · 2016-08-17T20:41:18Z

Hmm, 71fd4eb is still taking about 48 minutes with empty cache, when rebased on current master.

theuni · 2016-08-18T04:09:24Z

FYI I'm working on a qt 5.7 bump that changes the build significantly. I'm hoping for a reasonable speedup there.

laanwj · 2016-08-26T11:39:44Z

Closing this for now, can be reopened after the 5.7 bump.

laanwj · 2016-10-20T16:41:28Z

@theuni how is the qt bump going?
