This specifies a little the scope of the variable to make it
more realistic with the actual values it may have. We do have
a static typed compiled language, why don't we use it?
To be able to search in this for every kind of operator.
As we cannot do a migration, we have to add a new key to the property
dictionary (@"version_number") which stores the version:
version = exchange_globcnt(CN >> 16)
Instead of the CN structure which is stored in @"version" key.
This way we can do searches for CN to download only missing data from the
given state of the client for this kind of messages.
The operation RopFastTransferSourceCopyTo calls the available
properties for a message using the instance method. It seems the
preferred method by Outlook to synchronise a FAI message. OpenChange
calls the message to get the available properties, so the instance
method is called. As it is specialised to return the custom hack
FAI properties, we have to call that class method instead of using
generic one available at NSObject (MAPIStoreProperties) class.
This avoids crashing the Outlook client after we synchronise the
calendar folder after changing the timeframe view (eg from day view
to month view).
There were cases where only the change key was updated (GCS) or
others were the change key was updated with wrong info.
This changeset has as goal to update the predecessor change list
and, change key if required, on saving taking into account the latest information
given by the client in high level ROPs such as ImportMessageMove
or SetProperties, and merge it with information provided by the server
backend (IMAP server, SOGo DB) using `synchroniseCache`.
