possible 1.8.3 / 1.9.1 intertalk issue

[vikarti]

I have system which was running 1.8.3+I2P patches(from Killyourtv.i2p) later it was updated to 1.9.1 CentOS 5 I also have this from deep-check on

/root/tahoe is path to old tahoe install(1.8.3 i2p one needed to be installed with python 2.6 for some reason)

1.8.3/i2p is no longer in $PATH/PYTHONPATH(but this folder is still present on machine).

tahoe --version from this machine

[root@lalangamena .tahoe]# tahoe --version

I don't exactly knew how this happen. how they become intermingled.as I said - old one is not in PATH/PYTHONPATH. Moving /root/tahoe away resulted in

[root@lalangamena ~]# tahoe restart
Traceback (most recent call last):
  File "/root/tahoe-new/allmydata-tahoe-1.9.1/support/bin/tahoe", line 9, in <module>

so this looks like 1.9.1's setup.py somehow got it's hands on parts of old install?

[killyourtv]

FWIW, the I2P installer script will use whatever "python" points to, it doesn't depend on python2.6.

At the end of the installation you're advised to set the PATH and PYTHONPATH accordingly. I'd guess that you may have left the old installation defined in the PATH.

Make sure the old path is not defined in PATH and PYTHONPATH then try to reinstall.

[davidsarah]

Possibly related to #1669 (notice the "ValueError (need more than 8 values to unpack)"), but the mixture of 1.8.3 and 1.9.1 code means that we can't conclude anything concrete from this traceback.

How was the installation updated to 1.9.1? Using tahoe setup.py install? It seems as though it is using the 1.9.1 Tahoe code with the dependencies (Twisted, foolscap, etc.) that were installed for 1.8.3+I2P. That could result in using a wrong version of a dependency if its requirement changed, although it is not as bad as mixing files within the same Python package.

[davidsarah]

After moving /root/tahoe back, please do tahoe --version-and-path

Replying to vikarti:

how? I don't use install. just python setup.py build / python setup.py test on new one

Oh, ok. I was confused by the /root paths and the fact that you're using tahoe to run. You should be using bin/tahoe (in this case /root/tahoe-new/bin/tahoe) to run an instance of Tahoe that has been built rather than installed.

What does

root@lalangamena ~]# which tahoe

say?

BTW, I don't recommend running Tahoe as root.

[davidsarah]

Replying to killyourtv:

At the end of the [1.8.3+I2P] installation you're advised to set the PATH and PYTHONPATH accordingly.

Oh, that could confuse things no end. It shouldn't be necessary to set PYTHONPATH; as long as you're running the tahoe script that is in the bin/ directory of the build you want, that should be sufficient.

[vikarti]

at this time

[root@lalangamena ~]# which tahoe
/root/tahoe-new/allmydata-tahoe-1.9.1/bin/tahoe

which is correct. I can't reproduce this one(with 1.8.3 paths) anymore

It shouldn't be necessary to set PYTHONPATH; as long as you're running the tahoe script that is in the bin/ directory of the build you want, that should be sufficient. If you set PYTHONPATH as well, then you're explicitly asking for a mixture of the code pointed to by PYTHONPATH and the code from that build.

That was a holdover from when duck was handling it. I'll test without PYTHONPATH being set and report back if it is required. If it is not needed (of course) I'll advise people to not set it any longer.

OK, thanks.
