1143.3.8	Merge trunk: Merge trunk:	Jay Pipes	15 years ago
1143.3.7	Fix up duplicate plugin names in transaction log as well as ... Fix up duplicate plugin names in transaction log as well as fix 2 transactoin log test cases to remove non-deterministic columns from output.	Jay Pipes	15 years ago
1143.3.6	Merge trunk Merge trunk	Jay Pipes	15 years ago
1143.3.5	Merge trunk Merge trunk	Jay Pipes	15 years ago
1143.3.4	Adds INFORMATION_SCHEMA views for the transaction log: Adds INFORMATION_SCHEMA views for the transaction log: TRANSACTION_LOG TRANSACTION_LOG_ENTRIES TRANSACTION_LOG_TRANSACTIONS Adds a new user-defined function: PRINT_TRANSACTION_MESSAGE(filename, offset) Adds tests for all of the above Implementation notes: An indexer now runs when transaction messages are applied to the transaction log. It creates a simple index of the transaction log entries. This index is used when the information schema views' fillTable() method is called.	Jay Pipes	15 years ago
1143.3.3	Fix stupid error in calculation of filename vs. filepath in Fix stupid error in calculation of filename vs. filepath in transaction log.	Jay Pipes	15 years ago

1143.3.1	Merge trunk Merge trunk	Jay Pipes	15 years ago
1143.2.35	Adds support for BLOB fields in the replication stream. Note... Adds support for BLOB fields in the replication stream. Note that this does not yet support extremely large BLOB data. Extremely large BLOB data will be written to the transaction log in specialized transaction log entries for that. In this patch, we simply allow the main Transaction message and the reader/writer programs to work with binary data properly. Adds a simple test for BLOB fields and the transaction log. The problem was figuring out how to correctly replace embedded NUL characters in the output of the transaction reader with \\0 so that mysqltest.cc wouldn't puke when cat'ing the result of the reading of the transaction log when BLOB data was contained.

1143.2.34	Updated filtered_replicator test due to new tests for UPDATE... Updated filtered_replicator test due to new tests for UPDATE.	Jay Pipes	15 years ago
1143.2.33	This patch fixes a bug in the replication service and transa... This patch fixes a bug in the replication service and transaction proto file that was occurring when an UPDATE statement was SETting a field to a value by referencing the field itself. For instance, imagine the following scenario: CREATE TABLE t1 (id INT NOT NULL PRIMARY KEY, count INT NOT NULL); INSERT INTO t1 (id, counter) VALUES (1,1),(2,2),(3,3); UPDATE t1 SET counter = counter + 1 WHERE id IN (1,2); Previously, the UpdateHeader message contained a single set_value byte array containing the new value to set the field to. However, in scenarios such as the above, for each record being updated, the value that the field would be set to is different. Therefore, this patch moves the set_value byte array from the UpdateHeader message into the UpdateRecord message and names it after_value to match the existing before_value byte array. This patch adds a test case to the existing update.test case in the transaction log suite and modifies the statement_transform library to properly handle the above scenario.	Jay Pipes	15 years ago
1143.2.32	Merge trunk Merge trunk	Jay Pipes	15 years ago
1143.2.31	Add test case for when a transaction is manually started but... Add test case for when a transaction is manually started but no data modification occurs. This happens, for instance, when sysbench runs, and was causing major performance degradation because lots of blank transactions were being written to the transaction log needlessly.	Jay Pipes	15 years ago
1143.2.30	Mac doesn't have fdatasync() :( transaction_log.cc now uses Mac doesn't have fdatasync() :( transaction_log.cc now uses mysys/my_sync.cc's my_sync() call to handle this.	Jay Pipes	15 years ago
1143.2.29	Added fdatasync() calls to transaction_log.cc. Not sure how... Added fdatasync() calls to transaction_log.cc. Not sure how nobody caught this :)	Jay Pipes	15 years ago
1143.2.28	Moves all calls to replication services' commitNormalTransac... Moves all calls to replication services' commitNormalTransaction() into the ha_commit_one_phase() block.	Jay Pipes	15 years ago
1143.2.27	Corrects problems where REPLACE and INSERT ... ON DUPLICATE ... Corrects problems where REPLACE and INSERT ... ON DUPLICATE KEY UPDATE were not properly logging the atomic change in server state to the transaction log. The problem had to do with the log_row_for_replication() method not completely understanding whether a call to ha_update_row() had really been called during a REPLACE or INSERT call. See my blog entries for an overly-elaborate explanation as to what was really going on: http://www.jpipes.com/index.php?/archives/301-Pop-Quiz-What-Does-REPLACE-Do.html http://www.jpipes.com/index.php?/archives/303-The-Deal-with-REPLACE-..-Or-Is-It-UPDATE.html http://jpipes.com/index.php?/archives/305-Yet-Another-Post-on-REPLACE.html Added test cases for REPLACE and INSERT .. ON DUPLICATE KEY UPDATE.	Jay Pipes	15 years ago
