[tryton-debian] Bug#847436: tryton-server: Upgrade does not work without tryton-modules-webdav

[Raphaël Hertzog]

Source: tryton-server
Version: 4.2.0-1
Severity: important

I'm upgrading a 3.8 instance towards 4.2 (on a jessie system) and in the
process tryton-modules-webdav has not been installed.

When I try to run the upgrade process I get this failure:

$ sudo -u tryton trytond-admin -c /etc/tryton/trytond.conf --all -d tryton
Traceback (most recent call last):
  File "/usr/bin/trytond-admin", line 21, in <module>
    admin.run(options)
  File "/usr/lib/python2.7/dist-packages/trytond/admin.py", line 53, in run
    pool.init(update=options.update, lang=list(lang))
  File "/usr/lib/python2.7/dist-packages/trytond/pool.py", line 155, in init
    lang=lang)

    _load_modules()

    graph = create_graph(module_list)[0]
  File "/usr/lib/python2.7/dist-packages/trytond/modules/__init__.py", line 159, in create_graph
    info = get_module_info(module)
  File "/usr/lib/python2.7/dist-packages/trytond/modules/__init__.py", line 143, in get_module_info
    with tools.file_open(os.path.join(name, 'tryton.cfg')) as fp:
  File "/usr/lib/python2.7/dist-packages/trytond/tools/misc.py", line 76, in file_open
    raise IOError('File not found : %s ' % name)
IOError: File not found : /usr/lib/python2.7/dist-packages/trytond/modules/webdav/tryton.cfg 

BTW, the NEWS.Debian should really instruct the user to run the upgrade
with the rights of the tryton user (it suggests root since the command
line starts with "#") and it should also include the "-c /etc/tryton/trytond.conf"
otherwise you get other weird failures like this one:
$ sudo -u tryton trytond-admin --all -d tryton
Traceback (most recent call last):
  File "/usr/bin/trytond-admin", line 18, in <module>
    config.update_etc(options.configfile)
  File "/usr/lib/python2.7/dist-packages/trytond/config.py", line 73, in update_etc
    read_files = self.read(configfile)
  File "/usr/lib/python2.7/ConfigParser.py", line 302, in read
    fp = open(filename)
TypeError: coercing to Unicode: need string or buffer, NoneType found

And the "-v" flag would be welcome as well, otherwise you have the
feeling that the upgrade gets stuck and you wonder what is going on.

Cheers,
