* improve documentation for key: True flag in attributes.yml
* improve documentation for the ldap filters and their templating
* improve comment in the .ini file
previously, the default logger was passed, this logger was using the
default configuration and log level, not honoring log level in
particular.
As a consequence, it was impossible to get debug logs from the backend.
This is now working as expected.
The id of the user is passed through the querystring in this page.
But the id was not properly escaped to be included as a querystring
parameter leading to weird issues like.
Now the escaping is done by in the templates.
We need to remove the previous escaping done by hand in the code.
Otherwise, we end-up with double escaping and funky displaying of
fields.
* few small cleanup in html template (avoid empty tbody, put id between
quotes)
* switch to tidylib to validate the html instead of the previous hack
calling an external service (https://html5.validator.nu/)
* remove the previous validator script
* add exception for tidylib on empty <span> (these are required by
bootstrap)
With python 2 it was possible to do exception[0][...] to recover
details about an exception.
It's no longer authorized with python 3.
Now, we must do something like exception.args or exception.urls.
fortunately this syntax also works with python 2.
So we use it for both.
in python 2, (html) escape is part of the cgi module
in python 3, it's part of the html module
we now do a conditional import depending on the version, and name the
function html_escape.
python-ldap talks in bytes,
as the rest of ldapcherry talks in unicode utf-8:
* everything passed to python-ldap must be converted to bytes
* everything coming from python-ldap must be converted to unicode
The previous statement was true for python-ldap < version 3.X.
With versions > 3.0.0 and python 3, it gets tricky,
some parts of python-ldap takes string, specially the filters/escaper.
so we have now:
*_byte_p2 (unicode -> bytes conversion for python 2)
*_byte_p3 (unicode -> bytes conversion for python 3)
*_byte_p23 (unicode -> bytes conversion for python AND 3)
