When mysqlbinlog was given the --database=X flag, it always printed
'ROLLBACK TO', but the corresponding 'SAVEPOINT' statement was not
printed. The replicated filter(replicated-do/ignore-db) and binlog
filter (binlog-do/ignore-db) has the same problem. They are solved
in this patch together.
After this patch, We always check whether the query is 'SAVEPOINT'
statement or not. Because this is a literal check, 'SAVEPOINT' and
'ROLLBACK TO' statements are also binlogged in uppercase with no
any comments.
The binlog before this patch can be handled correctly except one case
that any comments are in front of the keywords. for example:
/* bla bla */ SAVEPOINT a;
/* bla bla */ ROLLBACK TO a;

Several items said to be deprecated in the 4.1 manual
have never been removed. This worklog adds deprecation
warnings when these items are used, and warns the user
that the items will be removed in MySQL 5.6.
A couple of previously deprecation decision have been
reversed (see single file comments)
escaped field names
When in mixed or statement mode, the master logs LOAD DATA
queries by resorting to an Execute_load_query_log_event. This
event does not contain the original query, but a rewritten
version of it, which includes the table field names. However, the
rewrite does not escape the field names. If these names match a
reserved keyword, then the slave will stop with a syntax error
when executing the event.
We fix this by escaping the fields names as it happens already
for the table name.
Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.
For application compatibility reasons MySQL converts "<autoincrement_column> IS NULL"
predicates to "<autoincrement_column> = LAST_INSERT_ID()" in the first SELECT following an
INSERT regardless of whether they're top level predicates or not. This causes wrong and
obscure results when these predicates are combined with others on the same columns. Fixed
by only doing the transformation on a single top-level predicate if a special SQL mode is
turned on (sql_auto_is_null).
Also made sql_auto_is_null off by default.

The 'BEGIN/COMMIT/ROLLBACK' log event could be filtered out if the
database is not selected by --database option of mysqlbinlog command.
This can result in problem if there are some statements in the
transaction are not filtered out.
To fix the problem, mysqlbinlog will output 'BEGIN/ROLLBACK/COMMIT'
in regardless of the database filtering rules.

"load data" statements were written to the binlog as a mix of the original statement
and bits recreated from parse-info. This relied on implementation details and broke
with IGNORE_SPACES and versioned comments.
We now completely resynthesize the query for LOAD DATA for binlog (which among other
things normalizes them somewhat with regard to case, spaces, etc.).
We have already parsed the query properly, so we make use of that rather
than mix-and-match string literals and parsed items.
This should make us safe with regard to versioned comments, even those
spanning multiple tokens. Also no longer affected by IGNORE_SPACES.
The --hexdump option crashed mysqlbinlog when used together
with the --read-from-remote-server option due to use of
uninitialized memory.
Since Log_event::print_header() relies on temp_buf to be
initialized when the --hexdump option is present,
dump_remote_log_entries() was fixed to setup temp_buf to point
to the start of a binlog event as done in
dump_local_log_entries().
The root cause of this bug is identical to the one for
bug #17654. The latter was fixed in 5.1 and up, so this
patch is backport of the patches for bug #17654 to 5.0.
Only 5.0 needs a changelog entry.

Signed integer format specifier forced to print the binlog header with server_id
negative if the unsigned value sets the sign-bit ON.
Fixed with correcting the specifier to correspond to typeof(server_id) == ulong.
Replaced Unix calls with mysql-test-run's built-in functions / SQL manipulation where possible.
Replaced error codes with error names as well.
Disabled two tests on Windows due to more complex Unix command usage

slave
The stored-routine code took the contents of the (lowest) parser
and copied it directly to the binlog, which causes problems if there
is a special case of interpretation at the parser level -- which
there is, in the "/*!VER */" comments. The trailing "*/" caused
errors on the slave, naturally.
Now, since by that point we have /properly/ created parse-tree (as
the rest of the server should do!) for the stored-routine CREATE, we
can construct a perfect statement from that information, instead of
writing uncertain information from an unknown parser state.
Fortunately, there's already a function nearby that does exactly
that.
---
Update for Bug#36570. Qualify routine names with db name when
writing to the binlog ONLY if the source text is qualified.
Problem: a typo in the code. When autocommit, foreign_key_checks,
sql_auto_is_null, or unique_checks changes, it prints "SET", and then a
comma-separated list of assignments. However, it does not print the
assignment to the @@autocommit variable.
Fix: print the @@autocommit variable.
Problem: in mixed and statement mode, a query that refers to a
system variable will use the slave's value when replayed on
slave. So if the value of a system variable is inserted into a
table, the slave will differ from the master.
Fix: mark statements that refer to a system variable as "unsafe",
meaning they will be replicated by row in mixed mode and produce a warning
in statement mode. There are some exceptions: some variables are actually
replicated. Those should *not* be marked as unsafe.
BUG#34732: mysqlbinlog does not print default values for auto_increment variables
Problem: mysqlbinlog does not print default values for some variables,
including auto_increment_increment and others. So if a client executing
the output of mysqlbinlog has different default values, replication will
be wrong.
Fix: Always print default values for all variables that are replicated.
I need to fix the two bugs at the same time, because the test cases would
fail if I only fixed one of them.

The reason of this bug is that when mysqlbinlog dumps a query, the query is written to
output with a delimeter appended right after it, if the query string ends with a '--'
comment, then the delimeter would be considered as part of the comment, if there are any
statements after this query, then it will cause a syntax error.
Start a newline before appending delimiter after a query string

The client program 'mysqlbinlog' crashed when trying to print a User_var_log_event holding
a floating-point value since the format specifier for my_b_printf() does not support
floating-point format specifiers.
This patch prints the floating-point number to an internal buffer, and then writes
that buffer to the output instead.
When running mysqlbinlog on a 64-bit machine with a corrupt relay log,
it causes mysqlbinlog to crash. In this case, the crash is caused
because a request for 18446744073709534806U bytes is issued, which
apparantly can be served on a 64-bit machine (speculatively, I assume)
but this causes the memcpy() issued later to copy the data to segfault.
The request for the number of bytes is caused by a computation
of data_len - server_vars_len where server_vars_len is corrupt in such
a sense that it is > data_len. This causes a wrap-around, with the
the data_len given above.
This patch adds a check that if server_vars_len is greater than
data_len before the substraction, and aborts reading the event in
that case marking the event as invalid. It also adds checks to see
that reading the server variables does not go outside the bounds
of the available space, giving a limited amount of integrity check.
