[resolved] bitcoin 0.13.0 tests fail with python-3.4

[AliceWonderMiscreations]

CentOS 7 user. That means system python is 2.7.5

That wasn't a problem with bitcoin 0.12.x

With bitcoin 0.13.0 it isn't a problem with building but it is a problem with make qa/pull-tester/rpc-tests.py

It wants python3 - I build in mock and python3 is in EPEL so I added python34 to the BuildRequires

Now when building it can find python3 but -

Code:

+ pushd src
~/build/BUILD/bitcoin-0.13.0/src ~/build/BUILD/bitcoin-0.13.0
+ srcdir=.
+ test/bitcoin-util-test.py
+ popd
+ qa/pull-tester/rpc-tests.py -extended
~/build/BUILD/bitcoin-0.13.0

During handling of the above exception, another exception occurred:

I'm guessing there is some python module I'm missing but its not an import error, so I don't know.

I'm not a python guru but I thought one of the reasons Python3 was suppose to be so great is because UnicodeEncodeError would be a thing of the past. Ah well.

Anyone know what I might be missing?

Right now the chroot buildroot environment *just* has python34 (Python 3.4), probably not what most people coding pythons scripts expect.

Any suggestions appreciated, especially suggestions that work.

Make an issue on Github about it.

It looks like this was fixed 15 days ago in master here.

As a workaround, check that your default locale ends in ".utf8" by running "localectl status". If it already does, then I'm not sure what workaround might work (unless you modified the locale just for your user).

If it doesn't end in ".utf8", see here to change it.

Thanks!

I'm attempting a build with

Code:

export LANG=en_US.utf8

before the test now. Hopefully that fixes it.

If not I may wait to update to 0.13.1 if the issue is fixed in git (but I'll do a git checkout to check)

[AliceWonderMiscreations]

I can confirm that fixes it. Thank you!
