This way, we can effectively kill all subprocesses. This worked for
slapproxy because Flask calls setsid internally, but slapgrid-* doesn't, so
they wouldn't be killed by killpg.

Fixes upgrade path from older erp5testnode version.

Note that it is useless to test simulation quantity in isSimulated
because even if it exists, we already failed to find a related SM.

This will be required to fix a possible race condition in causality_workflow

Otherwise, first test may fail if '--random_activity_priority=' option is used.

This fix is already applied to erp5.util.testnode, we duplicate
the fix. The code will move to library soon

The stop_condition() check is run once every beginning of loop tic, but if a loop
achieved a state of total failure, RuntimeError was raised before stop_condition()
had a chance to run.

So we call it again just one more time to see if we can avoid failing.

the code of some id generator can raise ValueError when objects
are not fully installed, and this is typically a case when the
compatibility code needs to run (like uid generation in the middle
of the installation of id generators objects)

This is used to get ongoing status even though there is no failures,
it allows to know what is going on on testnode side

This fix errors that could depend on environment (like python
version, mariadb version, etc)

The test was randomly failing since we were not getting last modification
date exactly the same way as the zope webdav support

Allow to override and address every individual menu item.

Css fixes.

- move "keep in draft state" field
- fix list of nodes displayed on event creation dialog
- display warning for mail message only

Forgot to drop extra threadframe references.

in Base_viewAddEventDialog:
- add sender&receiver
- change the destination state of the event based on who is the sender
- allow to keep event in draft state

in Event_viewCreateTicketWorkflowActionDialog:
- copy title from event
- make selection of resource dynamic based on ticket portal type
- fix some category definition on the created ticket

Changes to fix test_store_as_event from testNotificationTool and testMailFromMailMessageEvent from testERP5Credential

after_path_and_method_id argument was added to not activate when Crededial
request object is not indexed yet. This is needed because when the method
searchAndActivate from catalog is called, if the object is not indexed, the
e-mail is not sent.

And extended script Entity_sendEmail to use from_url parameter when it is not
None. This case happens when the sender is a string instead of one object in
ERP5
