Rev	Summary	Authors	Date
1143.2.15	This patch does the following: This patch does the following: 1) The transaction log now writes a 4-byte header containing the type of message which follows the header. This allows us to future-proof the transaction log in order to allow BLOBs to be written in chunks to the log file along with GPB Transaction messages. 2) The algorithm which writes Transaction messages to the transaction log has been improved. Instead of 3 separate calls to pwrite(), I have now reduced that to a single call to pwrite() and a raw buffer is used to construct the raw bytes that get written in bulk to the transaction log at the atomic offset. 3) Update the transaction_reader and transaction_writer programs for the above changes.

1143.2.12	Fixes 64-bit length encoding to be 32-bit, which is what is ... Fixes 64-bit length encoding to be 32-bit, which is what is supported by GPB. We will need to use a segment strategy for large blob records.	Jay Pipes	15 years ago

1143.2.10	Phase 2 new replication work: Phase 2 new replication work: * Removes old replication.proto file, old command_transform library * Removes use of korr.h macro calls in favor of GPB's CodedOutputStream API. * Updates transaction_log, default_replicator, and filtered_replicator module to use new Transaction message. * Updates ReplicationServices to construct the new Transaction messages and associated Statement sub-messages * Corrects transaction boundaries. AUTOCOMMIT now works properly, and I have added a new test case to verify AUTOCOMMIT variable modification of the way in which Transaction messages are bundled up and sent across to replicators.

1143.2.7	Based on IRC discussions with Brian, this patch reworks the ... Based on IRC discussions with Brian, this patch reworks the Statement message to SQL transformation code by having multi-key Insert, Update, and Delete statements generate multiple SQL strings. The transformStatementToSql() method now accepts a reference to a vector of strings, and when it finds a Statement message which should be converted to multiple SQL strings, it appends a transaction start and commit/rollback around the SQL strings which would compose an atomic unit of change. See the transaction_writer.cc and transaction_reader.cc program updates for example code of how the new library interface works.	Jay Pipes	15 years ago

New transaction proto file containing message definitions to be used in new replication system, which supports group commit behaviour. New statement_transform library files with utility methods used in converting transaction messages into SQL strings. Update transaction_reader and transaction_writer programs to use CodedOutput and CodedInputStream from GPB library and got rid of calls to korr.h macros entirely.	Jay Pipes	15 years ago
