define security on the right class
use newstyle class so that slots is effective
cleanup whitespace and indentation

This reverts commit ca125dac which came
from a misunderstanding. The code does not modify or convert any date, it just
display a default timezone when creating a new object.

Also fix the date field to have a timezone property in former proxy field library

This reverts commit fd28ecaf which is no longer needed as the try/except of the NotConverted exception has been fixed at a lower level

Redefining class prevent the try/except from working as
it is not the same class which is raised.
Fix import order to prevent looping

Take into account remarks done by Julien and Vincent.
Also stop using deletePycFiles for git repositories, git clean -fdx
is doing better (it remove more useless files if needed)

this generated errors when looking at alarm results

Using an instance of the class from the script create a huge memory leak
in zope which does not happen when instanciating class from the code.
The issue seems to come from the use by the matribox as simple test cases
of instanciation from script do not reproduce the memory leak

It is automatically created and provided by the ondatachannel event listener.
This bypasses some Chrome bugs.

This converts the WebSocket/RTC APIs into renderJS methods.

because inkscape DPI handling differs by its value.

Drop dead code.
Update a few archaisms.
Simplify code.
Improve coding style, reduce indentation.
Escape rendering.

Add support for visibility checking.
Use portal_type accessors, not properties.
Also, original implementation of getDefaultModuleId would get the object,
then its id. getDefaultModuleValue using it, it was getting the object,
then its id, then the object again...
Also, follow naming convention: getters returning documents are named
getXxxValue, not getXxx.

Favicons accidentally got lost in the change.

Reduce fragmentation by aggregating chunks when writing.
Aggregation is controlled by two new properties, chunk_size and
max_chunk_size.
Implement defragmentation.

Code tolerates this with no change.
Allows jumping to an existing relation without having to hard-code
(potentially a lot of) portal types.

Also, do not use getBaseCategoryDict to avoid mutating cached value and use
a set rather than a None-value dict.
Also, access portal_categories from portal explicitly rather than relying
on acquisition.

"to split" is an irregular verb.
Also, drop badly-worded comment.

Accelerate debugging by providing relevant values right away.

getPhysicalPath is too slow to be called this often.
Flush cache on object clone, which is only useful as an after-renaming
event here.
