This reverts commit 89aa2a6b.
The assumption that FOR UPDATE was unnecessary is wrong: when SQLDict
reserves similar activities, it will race against these primo-reservations.
So this change actually opens the possibility for duplicate activity
reservation.
Revert this change until (hopefully) a better fix is implemented.

In case of network problems, the http requests made to google during
login may take too long and cause global unavailability of the ERP5
instance.

Today we saw in long request logs:

oauth2client does not expose an API to set a timeout, but it allows
passing a custom http instance where we can set a timeout.

On Zope2 this method does not exist and this caused a test failure

To write a pid file so that logrotate can send us signals. This is
still needed for neo storage for now.

See nexedi/slapos!1395

Loading ZConfig will initialize storage and generally might do things
that will cause messages to be emitted.
One actual problem is with neo storage, which configure root logger
when it's not already configured [1], this was causing all logged
messages to be logged in the console when using neo storage.

It is easy to see contents ordered by id by default in ERP5Site.

Protect data from human error. There are unbelievable mistakes. ERP5
is a place to store important data that must not be deleted easily.

Errors in getObject (typically, unauthorized) were hidden by another
error in finally block, because popRequest can only be called if
pushRequest was executed before.

The roles were missing

Thanks to Vincent Pelletier for his help on this bug fix.

also set hide_rows_on_no_search_criterion to force displaying the list
even without search, this is a report, we we always want to see records.

This is done on the process running test (by
ERP5TypeTestCaseRequestConnection) and when using timerserver loop (by
TimerServer which calls publish_module), but this was never set in
processing_node.

Before 3b874e49 (ERP5Type/tests: review requests in tests, 2023-04-19)
getRequest could find a request anyway, because the test pached
getRequest to find a request from the app, but after this change
executing activities in an instance running with runUnitTest without
test specified failed with:

    Module importlib, line 37, in import_module
      __import__(name)
    Module Products.ERP5Type.dynamic.component_package, line 412, in load_module
      return self.__load_module(fullname)
    Module Products.ERP5Type.dynamic.component_package, line 379, in __load_module
      erp5.component.ref_manager.add_module(module)
    Module Products.ERP5Type.dynamic.dynamic_module, line 75, in add_module
      self.add_request(get_request())
    Module Products.ERP5Type.dynamic.dynamic_module, line 53, in add_request
      self.setdefault(last_sync, (WeakSet(), set()))[0].add(request_obj)
    Module _weakrefset, line 86, in add
      self.data.add(ref(item, self._remove))
  TypeError: cannot create weak reference to 'NoneType' object

( maybe we remove processing_node and use only timerserver, these two
methods are more or less equivalent for simple cases and timerserver is
closer to what a "real" zope does )

unittest executes the cleanups after `tearDown`, after the ZODB
connection is closed, so accessing database objects cause errors.

According to python unittest documentation, it is safe to call
`doCleanups` ourselves when we need the cleanup to be executed earlier,
this is a typical case where we want the cleanup to be called before
closing the database connections.

ID is not something we like to show to users, modification date and
validation state can be better - this assumes that most of the
relation are made to nodes, which typically have a validation state
and not a simulation state.

The general idea of this patch is that now that we are using
zope.globalrequest, we no longer need to patch get_request, we can
simply call zope.globalrequest.setRequest with the request from the
test and restore the "real" request afterwards.

To achieve this, we reuse Testing.ZopeTestCase.connections.registry,
which already has the logic of cleaning up resources in the right place
and use a "Request" resource that calls setRequest(test_request) and
setRequest(real_request) when closed, so that:
 - test runs with an independant request
 - this test request is closed at the end
 - the real request is restored at the end

This also fixes a bug with self.publish when runnning
ERP5TypeLiveTestCase from portal_components of a running instance,
after a call to self.publish the current request was lost.

The testing for this revealed that ERP5TypeLiveTestCase.publish way
of dealing with zope.security interaction was not always correct: when
running a live test inside runUnitTest (like we do here in
testDynamicClassGeneration), there is no security interaction. This
was reviewed to use the high level API instead of changing directly the
internal storage.

This can be useful when making a report on movements and when we list
properties of the movements that depend on the side but are not
directly exposed on MovementHistoryListBrain. One use case was
`Movement_getSpecificReference`, which shows `source_reference` when
the brain is for the source and `destination_reference` otherwise.

With this new approach, instead of guessing we record the "is_source"
information at indexing time, when we know this for sure.

This also simplifies `MovementHistoryListBrain.date` and
`MovementHistoryListBrain.mirror_date` which no longer need to guess
the side and fix a problem that because this guessing was done using
`movement.getSourceUid()` - which cause security errors when users can
not access the source of the movement.

When editing a state permission mapping the roles were not sorted,
because WorkflowState_getPermissionMatrixContext uses a set. Sort
before setting the attribute, to prevent useless diffs in ZODB history
and business template.

default activate() behavior is to not queue the activity if another
activity with the same path/method_id already exist. We don't want this
here.

We don't even use the new updateLocalRolesOnSecurityGroups instead,
because roles are supposed to be applied by an interaction workflow.

to make it easier to find related documents

This compatibibility script was guessing the side, but this is exposed
in brain

The way addToDate was working with dates was not good, and creating
confusion when removing 1 month from the last days of a 31-day month, as
the previous day had less days than the current month:

date = DateTime(2023, 5, 31)
print date
print addToDate(date, month=-1)
> 2023/05/31 00:00:00 GMT+2
> 2023/05/01 00:00:00 GMT+2

This was even more confusing in March, with february having only 28
days:

date = DateTime(2023, 3, 31)
print date
print addToDate(date, month=-1)
> 2023/03/31 00:00:00 GMT+2
> 2023/03/03 00:00:00 GMT+2

The new behavior is to, when removing a month, if the new day of the new
month is more than the number of days in month to default to the last
day of the month. For exemple, removing one month from 31/05 becomes
30/04, and from there it will add/remove the days as necessary.

The real issue being that removing a month is ambiguous and can mean
a different thing for different people.

For reference, the reference implementation of timedelta in python
doesn't support adding months:

https://docs.python.org/3/library/datetime.html#datetime.timedelta

I hope my solution will make the more sense in ERP5's context.

For zope, a request to /erp5/person_module/person1 or
/erp5/organisation_module/person_module/person1 can both be resolved
and are (more or less) equivalent. This change brings support for
similar request paths for Open API Connectors.

( until we finalize the complete integration of SlapOS parameter
editor )
