_Z2HOST / _Z2PORT no longer exist in Zope4, something was added in
component/egg-patch/Zope/0001-OFS-XMLExportImport.patch in SlapOS
software release, but we never had a strong need to patch there, we
were doing this so that Testing.ZopeTestCase.utils.makerequest creates
a REQUEST to this host:port, but now that Zope's startZServer no longer,
the REQUEST created by Testing.ZopeTestCase.base.app is always to
nohost:80, so we need to rewrap the app in request to our host:port.

Update to https://github.com/plone/Products.PortalTransforms/blob/3.2.0/Products/PortalTransforms/transforms/rest.py
because Zope4 no longer ship with a reStructuredText module and recommend
using docutils directly instead, which is what upstream did.

( in zope4py2 branch this was working because slapos patch
component/egg-patch/Zope/0001-OFS-XMLExportImport.patch used to bring
back reStructuredText but we don't seem to need it )

_Z2HOST / _Z2PORT no longer exist in Zope4, something was added in
component/egg-patch/Zope/0001-OFS-XMLExportImport.patch in SlapOS
software release, but we never had a strong need to patch there, we
were doing this (I guess) so that Testing.ZopeTestCase.utils.startZServer
knows that a server is already running and refuse to start another one,
but now that Zope's startZServer no longer exist, a local variable is
just fine.

Use correct portal type.

- Display the editor in ERP5 language, not browser language
 - Use PDF viewer for Drawing preview
 - Supports password protected PDFs
 - Others small changes

and several small fixes or changes to make this easier

This was a workaround for ChromeOS, but we realized it was not really good.
Disable it for the same reasons as slapos!1196 :

 - not everybody use ChromeOS
 - this breaks the ctrl+click shortcut to go to definition/follow link
 - it makes ERP5 monaco editor behaves differently from others monaco editor
 - ChromeOS users can use chrome://flags/#use-search-click-for-right-click

When cleaning up Wendelin from restricted python pandas code
(see https://lab.nexedi.com/levin.zimmermann/wendelin/tree/remove-redundant-pandas),
it turned out that there was one line still missing in erp5.
This missing line caused a failed test in wendelin functional tests:

  https://erp5js.nexedi.net/#/test_result_module/20220614-1B46817BD/6

Readding the line fixed the test.

create_server returns either a BaseWSGIServer or a MultiSocketServer,
but add_task only exists in BaseWSGIServer - and the implementation is
simply [1]:

    def add_task(self, task):
        self.task_dispatcher.add_task(task)

by using self.task_dispatcher.add_task directly, we are compatible with
both cases.

This is relevant when running timerserver with runUnitTest, where we
create multiple sockets, one for http and one for web-dav.

The default TestCase.__call__ collects errors in a test result that
was never retrieved, so errors were silently ignored.

By using TestCase.debug , we let errors propagate.

Minimal reproduction is running directly (ie. not with python -m unittest)
a script like this:

    import unittest

    class T(unittest.TestCase):
      def method(self):
        print('ah ?')
        boom
        print('oh')

    t = T("method")
    t()  # no error
    t.debug()  # NameError: name 'boom' is not defined

This helps debugging concurrency problems

This allows running tests using a timer server loop, that will invoke
process timer on all subscribers.
The need for this is to test a custom tool using timer server.

It was enough for 2 nodes, but with 4 nodes I sometimes saw errors.

This was a deprecated method that no longer exists since ZEO 4
https://github.com/zopefoundation/ZEO/commit/5423f110ddc1034ea0954495957894c60f6da78c

_setUpDummyMailHost is also used to prevent accidentally sending "real"
emails, so we also like to have it enabled for other nodes.

jslint complain about trailing commas

It does not make any sense to open PDF files from this gadget.

Also remove duplicate line with documentProperties

This is intended to store sensitive documents that users will only
be able to view from ERP5, but not to easily print or download.

To use this, some customization is needed. First, PDF needs to be
saved with a password. Then, PDF_getContentPassword type based method
needs to be customized to return the password.

When using this, we use different password for each document, by
deriving a password from a master key using document properties (such
as document reference for example)

A new option render option, "language" is passed to the gadget. It is
a two letter code as used by Localier.

Both CKEditor and pdf.js have support for translations and already
include translations for many languages. Before this change, they were
auto detecting the browser language and displaying in the browser
language, ignoring the language that was selected in ERP5. With this
change, they use the language selected in ERP5.

For CKEditor, we need to set the language only it is actually supported,
otherwise CKEditor crash. pdf.js does not this, but we had to call
ourselves initialize - which is probably better, because it was a promise
not awaited.

I'm not sure what was the problem from this comment, but we render
the gadget in an iframe so there's no need to change the DOM like this.
Probably this was a problem in early versions when it was in the same
page.

also change the content type in so that they are exported as text in
business template

This is the URL to download, it currently does not support range
requests, but it sets cache headers properly, unlike /getData which
is an accessor
