Uploading a file via script (using launchpadlib) results in truncated file.

[Christopher Lee]

When adding a file to a milestone using launchpadlib we are seeing that a byte is being truncated from one of the files.

The file in question is the juju core source tarball[1]. If we upload the same file manually using the web UI it works as expected.

I suspect that (a) the file in question ends with a carriage return byte and (b) you're using Python 3 to do the upload. Could you confirm or deny these two things?

a) I'm not sure, what's the best way to test this?

b) this using python 2.7.12

@Colin, I grabbed the file that Chris mentioned in the bug bug report, and the last character is in fact a carriage return (0x0d).

Can we please get some movement on this as it is the only thing currently blocking our release automation?

Thanks.

This is essentially bug 1729754. There are possibly some differences in details, as there are a couple of different types of possible corruption (handling of line separators in the middle of the file, and handling of a CR at the end), but I'm working on a set of fixes that will cover both.
