[Bug 1612948] Re: axi-cache conversion to python3 broke the script

[dino99]

On bionic, getting rid of that error (dirty tweak until proper fix):

oem at ubuntu:~$ axi-cache
" No module named 'ConfigParser': only help functions are implemented, for the sake of help2man "

***********
First find location:
- ConfigParser.py from /usr/lib/python2.7
- configparser.py from /usr/lib/python3.6

As the axi-cache script request ConfigParser.py, then give it satisfaction:
" sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py "

Then tested with "axi-cache info" & "axi-cache show gdm3" : no more
complaint !!!

***********
Voila, simple dirty tweak, but works at least about the error; still need to know if apt-xapian-index works better or not.
The python3 port is still not complete, and python2.7 is still not completely removed. Will probably done with the 18.10 cycle.

If you want the same dirty tweak working on xenial, ..., then check the
pathes first.

Title:
  axi-cache conversion to python3 broke the script

Status in apt-xapian-index package in Ubuntu:
  Confirmed

Bug description:
  axi-cache, the script command line in apt-xapian-index, is now converted to python3.
  In python3 afaik module ConfigParser is now renamed in configparser.

  running axi-cache, throw an error:

  mizio at sammiz:~$ axi-cache 
  No module named 'ConfigParser': only help functions are implemented, for the sake of help2man

  if I edit axi-cache, fixing the module name (row 50, "from
  configparser import RawConfigParser" instead of "from ConfigParser..."
  all seems ok:

  
  mizio at sammiz:~$ axi-cache 
  Usage: axi-cache [options] command [args]

  Query the Apt Xapian index.

  Commands:
  <...>

  But this fix isn't sufficient. The script not seems to me really
  python3 compatible, ie:

  mizio at sammiz:~$ axi-cache search brasero
  4 results found.
  Results 1-4:
  100% b'brasero-cdrkit' - (unknown by apt)
  98% b'brasero-common' - (unknown by apt)
  77% b'gir1.2-brasero-3.0' - (unknown by apt)
  71% b'brasero' - (unknown by apt)
  Traceback (most recent call last):
    File "/usr/bin/axi-cache", line 852, in <module>
      sys.exit(ui.perform())
    File "/usr/bin/axi-cache", line 847, in perform
      return f(self.args)
    File "/usr/bin/axi-cache", line 547, in do_search
      self.print_matches(self.db.get_matches())
    File "/usr/bin/axi-cache", line 808, in print_matches
      sugg = self.clean_suggestions(self.db.get_suggestions(count=7, filter=DB.TermFilter(stemmer=self.db.stem, exclude=self.args)))
    File "/usr/bin/axi-cache", line 310, in get_suggestions
      return self.enquire.get_eset(count, rset, filter)
    File "/usr/bin/axi-cache", line 118, in __call__
      return term[0].islower()
  AttributeError: 'int' object has no attribute 'islower'

  for this reason I suggest to revert the "python3 conversion" or ask
  the upstream to convert the script.
