Change max age to 1 hour and 1 day

erp5_search_rank_catalog: do not destroy the previously calculated rank

erp5_search_rank_catalog: Show module content before tools content

erp5_search_rank_catalog: keep default value low, to prevent having huge rank score

Always reclaculate the full matrixbox content if one change is found.

Add mutex to prevent raise condition between render and getContent.

Drop not needed local cache.

With the new workflow implementation, error_message variable is required, because
we intentionally clone previous workflow history entries when passing transition,
as this leads to smaller pickle size

Use the html_viewer gadget

fix internal API mis-use and other small fixes

This was creating different message for each number of tasks

This uses an internal API that has changed in 0aeea3c4 (Validation
message translation, 2021-01-06)

With this, user can see stop_date from events

With TALES in default, we prevent acquisition from the start date. When default is None, the field will try to display now on the stop date.

The goal is, if stop_date is None, we don't display anything in this field.

stop date is very useful to Phone Call and Visit. For example, if you want to calculate the time spent in one phone call, you can handle it using start and stop date.

But, Event_view does not display stop_date. So, we display stop_date if hasDuration is True.

No need to introduce one more random number here,
anyway the tag that is passed to this script contains one, so use that

Base_report needs to get also the cleanup_tag
to make sure it is launched before active process is deleted

When rendering a proxy field, 3 different fields can come in play:
1. the field to be rendered
3. the template field (i.e. not a proxy field) that knows how to render
2. possibly an intermediate proxy field that contains the value to render

What's difficult when rendering a proxy field is to take the above 3 fields
into account and this commit does it by creating a temporary field:
1. 'field' variable in TALES
2. the value
3. the code

Before this commit, 1 could be wrong.

This was deprectated because we don't have get*ById for other modules
and tools, we just use OFS API. This should also be slightly faster
because one less method call (and one less call to warning)

exiting the context manager restores the original DateTime behavior

This tests the test framework, because this code is tricky.

I'm not sure if this is used, but not being valid python code cause
problems with code analysis tools

Maybe this made sense long time ago, but nowadays we are using
equivalence testers which tolerate date differences with more flexibility.

createDateTimeFromMillis was also problematic as it uses internal
private attributes of DateTime which is a pylint error with more recent
DateTime
