The error is like [1] where the file is not encoded utf-8.

1:

+ f = open(trfile, encoding='utf-8')

`f = open(trfile, encoding='latin-1')`

could be a (temporary?) solution.

Yes, it's the best long term solution.

Definitely. But who is providing that file?

`f = open(trfile, encoding='latin-1')`

could be a (temporary?) solution.

Andreas, it's possible that changing the encoding will fix the bug for
some files but you will get new errors on other files (encoded in
utf-8). Trying several encoding or using 'chardet' library could be a
better workaround.

Would you mind providing a patch with chardet?

Kind regards

Andreas.

Hi St�phane,

thanks for your patch which I applied in the python3 branch. Unfortunately
it does not solve the issue:


udd(python3) $ ./update-and-run.sh ddtp
Traceback (most recent call last):
File "/srv/udd.debian.org/udd//udd.py", line 88, in <module>
exec("gatherer.%s()" % command)
File "<string>", line 1, in <module>
File "/srv/udd.debian.org/udd/udd/ddtp_gatherer.py", line 127, in run
h.update(f.read())
File "/usr/lib/python3.8/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc5 in position 11: invalid continuation byte


Thanks a lot anyway

Andreas.

There is a patch attached to this e-mail.

I used [1] for the base file. I don't think the patch is great (because
there are two 'open()' calls) but it has minimal modifications of the
current source code. I think it's a better solution for the success the migration to python3 (because it avoid introducing bugs during the migration).

Feel free to ask for more explanations or other stuff if you need.

Hi,

Do all those people in Cc need to read this? If you really want to keep
this public, maybe debian-qa@ is enough? (I personally don't feel I
need to read this at this time; if I had time to spend on UDD, I would
fix actual bugs)

Thanks

Lucas

While you can download the files from any Debian mirror I've attached
/srv/mirrors/debian/dists/stretch-proposed-updates/main/i18n/Translation-en.bz2
to this mail. My guess is that translations from stretch will not be
touched any more and thus we need to cope somehow with the existing
encoding.

Thanks a lot for your help

Andreas.
