CopyCat v3.04.0 (4th of April 2013)

TCcReplicator

• Fixed a bug whereby empty string values were sometimes changed

into nulls.

• FIBPlus connector : improved recovery after connection loss :
  sometimes connection would not resume correctly after network error was
  fixed.
• CopyCat now checks the number of rows affected by either the
  update or insert into the destination database and raises an error if
  ever neither the update nor the insert was successful.

CopyCat V3.03.0 (1st of August 2012)

• New database adaptor for SQLite
• XMLRPC server and CopyCat transport server for iOS (written in
  objective-C, compatible with Delphi CopyCat XMLRPC transports.

• Added AutoCommit property on client transport. Setting
  autocommit optimizes communication by not explicitly starting nor ending
  transactions. This implies that the server side must automatically
  commit after executying every query.
• Added property EncodeStringsAsBase64 to TCcRtcClientTransport
  and TCcRtcServerTransport.

• Added parameters TableName and Fields to OnRowReplicated
  event, allowing to access the table name of the row just replicated, as
  well as the values of the fields transfered.
• Added parameters ReplicateRow and AbortAndTryLater to the
  OnRowReplicating event. If ReplicateRow is set to false, the row is not
  replicated and the row is discarded from RPL$LOG. If AbortAndTryLater is
  set to true, replication of the row is aborted, and will be tried again
  next replication cycle (ie, the row is left in RPL$LOG).
• Renamed OnAbort event OnReplicationAborted. It it called only
  when replication is explicitly aborted via the AbortReplication method
  or by setting CanContinue to false in the OnReplicationError event.
• Added property TrimCharFields. If set to True, TCcReplicator
  will trim all char, varchar or memo fields that are read from the source
  database before replicating them to the destination database.

• Added multi-configuration abilities. This means that multiple
  replication configurations can be created for the same database,
  allowing separate lists of tables, replication conditions, and
  replication nodes to be configured independantly from each other.
• You can now define replication configuration at design time,
  using the new Tables property. Double-clicking on this property allows
  you to define the list of tables to replicate for the current
  configuration (defined by the ConfigName property), along with the
  conditions for each, as well as the list of nodes to replicate towards
  (corresponding to the RPL$USERS table). You can then roll out this
  configuration at run time by calling the GenerateConfig property. This
  will create triggers for all the tables defined in your configuration,
  or recreate them if any of the configuration options has changed. If you
  want to define several replication configurations, then you need one
  TCcConfig instance for each configuration.
• New IncludedFields property in the Tables list allows you to
  specify the list of fields to include in the replication triggers. This
  means that the change will only be logged for replication (in RPL$LOG)
  if at least one of the included fields has changed. Thus empty updates
  or updates of fields that are of no interest to the replication config
  can be excluded, thereby lightening the replication load. If no
  IncludedFields are set, the default is to include all fields, as before.
• New IncludedFields property in the Tables list allows you to
  set a list of fields to exclude from the replication triggers. This is
  just a shortcut for adding all but the fields specified to the
  IncludedFields list.
• New procedure RPL$FORCE_REPL allows to force replication of a
  certain set of rows, within the context of a certain config. This can be
  useful when the IncludedFields property is used.
• Added multiple data types in order to handle all the new
  TDataType values. This fixes a bug that occured with some Firebird
  dialect 3 datatypes, when replicating over XMLRPC or RTC transports.
