[uilib] `uilib.js` helper now honors explicit JSString (closes #4959538) Previously, if a JSString was inside a nested container (i.e. list or dict), it was handled as a string, not a verbatim js chunk (see docstring and test). So the following code:: >>> str(js.cw.pouet(1, {'callback': JSString('cw.mycallback')}) resulted in:: "cw.pouet(1, {'callback': 'cw.mycallback')})" while we expect (note the removed quotes):: "cw.pouet(1, {'callback': cw.mycallback)})" We use ``cubiweb.utils.js_dumps`` instead of ``cubicweb.utils.json_dumps`` which is aware of JSString.

from logilab.common.shellutils import generate_password
from cubicweb.server.utils import crypt_password

for user in rql('CWUser U WHERE U cw_source S, S name "system", U upassword P, U login L').entities():
    salt = user.upassword.getvalue()
    if crypt_password('', salt) == salt:
        passwd = generate_password()
        print 'setting random password for user %s' % user.login
        user.set_attributes(upassword=passwd)
