Subject: [PATCH 1/6] BUG#21490 - No warning issued for deprecated replication
 parameters This patch deprecates the replication startup options in the
 configuration file and on the command line. The options deprecated include:

MASTER_HOST, MASTER_USER, MASTER_PASSWORD, MASTER_PORT, MASTER_CONNECT_RETRY,
MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH, MASTER_SSL_CERT, MASTER_SSL_KEY,
and MASTER_SSL_CIPHER

The code is designed to print the warning message once.

Subject: [PATCH 2/6] Bug#25815 Data truncated for column TEXT Problem: "Data
 truncated" warning was incorrectly generated when storing a Japanese
 character encoded in utf8 into a cp932 column. Reason: Incorrect wrong
 warning condition compared the original length of the character in bytes
 (which is 3 in utf8) to the converted length of the character in bytes (which
 is 2 in cp932). Fix: use "how many bytes were scanned from input" instead of
 "how many bytes were put to the column" in the condition.

Subject: [PATCH 3/6] Fix for BUG#24432 "INSERT... ON DUPLICATE KEY UPDATE
 skips auto_increment values". When in an INSERT ON DUPLICATE KEY UPDATE,
 using an autoincrement column, we inserted some autogenerated values and also
 updated some rows, some autogenerated values were not used (for example, even
 if 10 was the largest autoinc value in the table at the start of the
 statement, 12 could be the first autogenerated value inserted by the
 statement, instead of 11). One autogenerated value was lost per updated row.
 Led to exhausting the range of the autoincrement column faster. Bug
 introduced by fix of BUG#20188; present since 5.0.24 and 5.1.12. This bug
 breaks replication from a pre-5.0.24 master. But the present bugfix, as it
 makes INSERT ON DUP KEY UPDATE behave like pre-5.0.24, breaks replication
 from a [5.0.24,5.0.34] master to a fixed (5.0.36) slave! To warn users
 against this when they upgrade their slave, as agreed with the support team,
 we add code for a fixed slave to detect that it is connected to a buggy
 master in a situation (INSERT ON DUP KEY UPDATE into autoinc column) likely
 to break replication, in which case it cannot replicate so stops and prints a
 message to the slave's error log and to SHOW SLAVE STATUS. For
 5.0.36->[5.0.24,5.0.34] replication we cannot warn as master does not know
 the slave's version (but we always recommended to users to have slave at
 least as new as master). As agreed with support, I'll also ask for an alert
 to be put into the MySQL Network Monitoring and Advisory Service.

From 8b1609a63717227b8931bb3a7fdaf45a43b831c7 Mon Sep 17 00:00:00 2001
From: "guilhem@gbichot3.local" <>
Date: Thu, 15 Feb 2007 15:39:03 +0100
Subject: [PATCH 4/6] Fix for BUG#25507 "multi-row insert delayed + auto
 increment causes duplicate key entries on slave" (two concurrrent connections
 doing multi-row INSERT DELAYED to insert into an auto_increment column,
 caused replication slave to stop with "duplicate key error" (and binlog was
 wrong)), and BUG#26116 "If multi-row INSERT DELAYED has errors,
 statement-based binlogging breaks" (the binlog was not accounting for all
 rows inserted, or slave could stop). The fix is that: if (statement-based)
 binlogging is on, a multi-row INSERT DELAYED is silently converted to a
 non-delayed INSERT. Note: it is not possible to test BUG#25507 in 5.0
 (requires mysqlslap), so it is tested only in the changeset for 5.1. However,
 BUG#26116 is tested here, and the fix for BUG#25507 is the same code change.

Subject: [PATCH 5/6] Backport from the Falcon tree. When opening/creating the
 transaction coordinator's log, if binlog is used, the tc log is the binlog so
 we use the binlog's name; otherwise we use the mmap-based log, named after
 the mandatory argument of the --log-tc option (meant for that).

Subject: [PATCH 6/6] the fix for BUG#24432   "INSERT... ON DUPLICATE KEY
 UPDATE skips auto_increment values" didn't make it into 5.0.36 and 5.1.16, so
 we need to adjust the bug-detection-based-on-version-number code. Because the
 rpl tree has a too old version, rpl_insert_id cannot pass, so I disable it
 (like is already the case in 5.1-rpl for the same reason), and the repl team
 will re-enable it when they merge 5.0 and 5.1 into their trees (thus getting
 the right version number).
