We’re pleased to announce the release of CopyCat Developer version 3.7.1!
The changes in this release are as follows:
– XE7 support
– Major performance and memory management improvements of big logs. Instead of loading the whole list of changes to replicate into memory at once, it is now streamed in row by row.
– The UPDATE OR INSERT statement is now used in FB 2.1+, in order to reduce the number of statements needed and thus optimize performance.
– Internal changes enabling the use of prepared queries during replication, thus again dramatically improving performance.
– Improved performance of TCcConnection.GetFieldType
– Fixed a memory leak that caused problems with long-running replication cycles.
– Fixed a bug in the millisecond handling in Firebird.
We’re pleased to announce a new minor release of CopyCat Developer, containing the following changes :
- Added method ConnectAndRemoveConfig to TCcConfig, allowing to entirely remove all replication meta-data (that is, the RPL$ tables, the triggers, etc) from the database. (Firebird/Interbase only).
- Added packages for NexusDB connector for old Delphi versions (D5 to XE4).
- Improved timestamp formatting when timestamp fields are used as part of a primary key, so that milliseconds and 100 microseconds are included. (Firebird/Interbase only).
- Improved floating point formatting when numeric fields are used as part of a primary key, so that the decimal formatting settings of the machine have no impact on the formatting used. (Firebird/Interbase only).
- Fixed a bug sometimes causing some of the tables of the database not to be found (Firebird/Interbase only).
- Added FireDAC connector package for XE4.
We are pleased to announce a new release of CopyCat Developer Tools, version 3.06.0! Registered users can download it from their private download page.
Changes in this release include :
- XE6 support
- NexusDB support
- Support for mobile platforms (iOS / Android)
- Added IBDAC connector
- Added DataSnap transport
- Added FireDAC connector
- Added new Demo project in Examples\Demo
- Added index on RPL$LOG.PRIMARY_KEY_VALUES in Firebird 2.5+ for the sake of optimization
- Added support for replicating tables with no primary key : in such cases, CopyCat will first look for any unique index to use instead of the PK, and if none are available, then rows will be identified based on all the fields of the table (excluding varchars longer than 200 characters and blobs).
- Added support for various field types that were missing (ftGuid in ADO connector, ftTimeStamp, ftFmtBCD, ftWord, ftLongWord…)
- Added TFDMemTable as an optional ancestor for TCcMemoryData, activated by setting compiler conditional CC_MEMDS_FIREDAC in CC.INC. Using this feature is necessary on mobile platforms, as the built-in memory dataset does not support the nextgen compiler.
- Added PKSynchronization property to TCcReplicator. If set to false (the default), the primary key synchronization system is disabled, which allows some optimizations of the code internally.
- Added Priority property in TCcConfigTable so you can set the replication priority of a table through the TCcConfig.Tables property.
- TCcReplicator.Log is now reinitilized at the very start of replication, before the log is loaded. That way, if replication is aborted and then restarted, the TCcLog.LineCount and CurrentLine properties will be correct.
- TCcReplicator now automatically disconnects if Replicate is called with a connection is already open, unless that connection had been opened by the replicator itself (using KeepConnection for example). That addresses a common mistake people made when trying to replicate, as a connection open outside of TCcReplicator will cause the rows replicated to bounce back and forth between nodes.
- Fixed problem in the installer causing the components to not be installed in the IDE
- Changed date format used for MS SQL to ‘YYYY-MM-DDThh:mm:ss[.mmm]’, so that it works in all locales.
- Fixed bug causing empty string to convert to NULL in some cases.
- Fixed several bugs causing binary blob data to get replicated incorrectly for ADO, RTC and XMLRPC connectors
- Fixed bug causing XMLRPC server to fail completely when using Indy 10 in the newer IDE versions
- Changed TCcConnection.InTransaction property to reflect value of underlying transaction object : thus, if a connection was lost, CopyCat will not erroneously consider the transaction to still be open.
- Fixed a bug causing the TCcReplicator.AutoCommit property to fail
- Fixed bug that caused replication of ftWideString fields to fail when using versions of Delphi older than BDS 2006.
- Various other minor bug fixes
