tests: Re-enable RPC tests for Windows

laanwj commented at 8:14 am on June 20, 2016: member

Try RPC tests in Travis windows builds.

Just a test, don’t merge this yet.

laanwj added the label Tests on Jun 20, 2016

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)

MarcoFalke commented at 9:11 am on June 20, 2016: member

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

laanwj commented at 9:12 am on June 20, 2016: member

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 commented at 10:01 am on June 20, 2016: member

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 commented at 10:43 am on June 20, 2016: member

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

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)

MarcoFalke commented at 3:09 pm on July 5, 2016:

Feel free to fix the nit in this pull.

MarcoFalke commented at 10:51 am on June 20, 2016: member

Thanks.

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

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.

laanwj commented at 12:39 pm on June 20, 2016: member

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

MarcoFalke commented at 3:04 pm on June 20, 2016: member

I’ve added a commit to https://github.com/bitcoin/bitcoin/pull/8216/commits/fa58f94ff7f097260ebee791008dab368c7ac318 which should improve that, but I think after enabling qt builds again, we are again at the limit…

laanwj commented at 8:31 am on June 21, 2016: member

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

tests: Accept quotes around alert message (windows compat)

`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.

tests: Re-enable RPC tests for Windows

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`.

MarcoFalke commented at 11:09 am on June 21, 2016: member

There was a timeout in

0  File "qa/pull-tester/rpc-tests.py", line 254, in get_next
1
2    (stdout, stderr) = proc.communicate(timeout=3)

but not due to the travis limit of 50 minutes.

MarcoFalke commented at 11:13 am on June 21, 2016: member

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 commented at 11:26 am on June 21, 2016: member

What is the three-second timeout waiting for?

MarcoFalke commented at 11:31 am on June 21, 2016: member

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.

MarcoFalke commented at 11:35 am on June 21, 2016: member

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.

MarcoFalke commented at 3:02 pm on July 5, 2016: member

@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.

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

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

MarcoFalke commented at 9:12 am on August 8, 2016: member

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 commented at 1:54 pm on August 13, 2016: member

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

MarcoFalke commented at 8:41 pm on August 17, 2016: member

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

theuni commented at 4:09 am on August 18, 2016: member

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

laanwj commented at 11:39 am on August 26, 2016: member

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

@theuni how is the qt bump going?
