Not only returns start and stop dates, but also quantity defined
on presence periods. This make it possible to set 3 hours availability
in a time range of 10 hours.

When a Group Calendar or a Group Presence Period is updated, it's necessary
to update related Group Assignment stock catalog data since values are dependent.

This allows to define specific security setting and workflow for Group Calendar Assignments. Before
they were inside Group Calendars. Now a Group Calendar Assignment use the specialise Base
Category to specify the corresponding Group Calendar.

Improve sql query to consider only accountable lines and get the avaibility with many nodes in the same query

Move changes on asMovementList method from PresencePeriod to GroupCalendarAssignment to keep Leave Period working as Expected.

This reverts commit cbf5d46e3c1d3e76c6a5376e08617851ce03773c.

remove the calendar base category on Assignment portal type because the relation between Assignment and Group Calendar is obsolete

Add Group Calendar Assignment portal type. It will be used to set the relation with the source and the period

otherwise pylint-1.2.0 seems not working.

ERP5VCS: fix error with recent versions of Git when there's no upstream configured for current branch

constraint_type should be a string instead of a list.

fixup! fix unicodeconflictresolver that was causing the same error when logging the problematic text

fillRecursivePathList could load massive amounts of objects (ex:
all signatures below portal_synchronizations) even if no object was to
be removed. Instead, just iterate given lists (objects handled by
current instance, and actions to perform) and do as much rocessng before
actually attempt to load any object.

Sadly, the data structures available to this code induce an ugly O(n*m)
code, which may be optimised to O(m + log(n)) with more complex code if
really needed (but then, data structure should be improved, with a much
broader effect).

It was unreliable because done only for the first test.
Code needing this information can simply call startZServer, which will simply
return host/port of already started ZServer.

because the list of threads for Anonymous should be provided through predicate in Web Section, not from the module itself.

this commit prevents generating needless activities at the beginning of tests.

No specific role should be defined for test-related portal_types.

ERP5ProjectUnitTestDistributor.startTestSuite doesn't know about computer_guid parameter.

This is a new preference for uses of resources that can be used when creating a response to an event. The create response dialog uses it in two places:
- Only resources with this uses are proposed
- Only notification messages that creates events with resource with this use are proposed
