[tahoe-dev] [tahoe-lafs] #734: Tahoe CLI with unicode patches applied fails when stdout is redirected

Thanks for that, I'll try it out - first apply the Unicode patch, then this

Should I still use unicode patch files used on 1.4.1 attached to
http://allmydata.org/trac/tahoe/raw-attachment/ticket/534 ? Will they apply

In the meantime, can anyone please help me with :


/usr/bin/python /usr/src/tahoe/darcs/09-08-05_18-15/tahoe/bin/tahoe backup

sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use
a text_factory that can interpret 8-bit bytestrings (like text_factory =
str). It is highly recommended that you instead just switch your application
to Unicode strings.

/usr/bin/python /usr/src/tahoe/darcs/09-08-05_18-15/tahoe/bin/tahoe
--version :

allmydata-tahoe: 1.5.0-r4043, foolscap: 0.4.2, pycryptopp: 0.5.16, zfec:
1.4.4, Twisted: 8.2.0, Nevow: 0.9.32, zope.interface: 3.5.0, python: 2.6.0,
platform: Linux-SuSE_11.1-x86_64-64bit_ELF, sqlite: 3.6.4, simplejson:
2.0.7, argparse: 0.8.0, pyOpenSSL: 0.7, pyutil: 1.3.30, zbase32: 1.1.1,
setuptools: 0.6c12dev, pysqlite: 2.4.1

I suspect this has nothing to do with missing Unicode patch, as the filename
in question has no characters that would be/should be unicode encoded?

Much appreciated,

Andrej Falout
