[Bug 1152222] Re: pycurl fails with TypeError: string argument expected, got 'bytes'

[Dmitrijs Ledkovs]

I'm not sure if this is a bug in pycurl. I see a few fixes w.r.t.
python3 bytes/string handling in pycurl uploaded by mterry (see
https://launchpad.net/ubuntu/+source/pycurl/+changelog ). My naïve
expectation is that "over the wire" we always pass and receive Bytes,
and it's our job to encode/decode that before sending/receiving.
Attaching a hacking patch, which makes thin-client-config-agent work
against pycurl in raring. Not sure if it will work against quantal and
earlier as well. Assigning to Mterry the pycurl portion of the bug
report & asking to review merge proposal as well.

Title:
  thin-client-config-agent fails in pycurl with TypeError: string
  argument expected, got 'bytes'

Status in “pycurl” package in Ubuntu:
  Confirmed
Status in “thin-client-config-agent” package in Ubuntu:
  Confirmed

Bug description:
  When using thin-client-config-agent, the recent release of the pycurl
  package breaks the Remote Login feature.

  The following test shows the error:

  echo -n "test" | /usr/bin/thin-client-config-agent test at example.com
  TypeError: string argument expected, got 'bytes'
  Exception: <class 'pycurl.error'>
  (23, 'Failed writing header')
  { "Error": "Contact your administrator" }

  This is the regression as of version 7.19.0-5ubuntu6 of the package.

  Previously, on quantal and up to raring 7.19.0-5ubuntu3 the expected result was:
  Invalid username or password
  { "Error": "Invalid username or password" }
