Bug #1322218 fix.

In the case if mysqld returns error don't continue mysql_install_db script
execution.

The second case when floating point error happens due to dividing by zero when
the number of records in "users" table is null or there is no such table is not
fixed as 5.1 does not contain such code.

Author: Vlad Lesin
Revision Date: 2014-09-09 12:21:53 UTC

Implement this
https://blueprints.launchpad.net/percona-server/+spec/binary-answer-5.6
blueprint.

The task can be splitted on server and client parts.

Server-side.

If we look into mysqld_stmt_prepare() function we can see the code like this:

Protocol *save_protocol= thd->protocol;
thd->protocol= &thd->protocol_binary;
stmt->prepare(...);
thd->protocol= save_protocol;

The THD class contains this members:

Protocol *protocol; // Current protocol
Protocol_text protocol_text; // Normal protocol
Protocol_binary protocol_binary; // Binary protocol

So for server-side is enough to add new command COM_STMT_EXECUTE_IMMEDIATE which
would do absolutely the same things as COM_QUERY does but with replacing
thd->protocol with &thd->protocol_binary before processing and restore protocol
pointer after processing.

Client side.

Standard C API has already have all necessary infrastructure to parse binary
protocol. So the task is to use this infrastructure. The idea is to add new
function mysql_stmt_execute_immediate() which would send
COM_STMT_EXECUTE_IMMEDIATE to server, initialize MYSQL_STMT object to use it
for parsing result with standard functions for parsing the result of
"execute prepared statement". As well mysql_stmt_bind_immediate() is necessary
to initialize certain MYSQL_STMT fields which are usually initialized inside of
mysql_stmt_prepare() and to invoke standard mysql_stmt_bind_result() function
to describe the result data.

There are two functions to execute prepared and non-prepared queries
correspondingly: mysql_stmt_execute() and mysql_real_query(). Both functions
use the same function cli_read_query_result() to get information about fields
count, their names. So this part of result parsing is the same. But rows parsing
is absolutely different.

For non-prepared query mysql_fetch_row()->read_one_row() calls just set pointers
in array of rows to the certain values in read packet. As all values are in the
text format we have the array of pointers to null-terminated strings as the
output of the function.

But when binary data are parsed in mysql_stmt_fetch()->stmt_fetch_row() the
functions use information about field types from MYSQL_STMT::bind array.
For each element of this array
mysql_stmt_bind_result()->setup_one_fetch_function() sets the pointer to the
function which parses binary data of corresponding type to the buffer. For
example fetch_result_int32() is set up for MYSQL_TYPE_LONG data type.

So we have to develop new function mysql_stmt_execute_immediate() which would
mix mysql_real_query() and mysql_stmt_execute().

Use tests/stmt_execute_immediate.cc as the source of information about the
sequence of C API calls to send query and receive and parse binary answer.

stmt_execute_immediate.cc could be the part of mysql_client_test.c but the
customer disabled this test in his tree.

The new parameter --binary-protocol is added to mysqltest to allow communication
between client and server with binary protocol without "prepare" using
mysql_stmt_execute_immedate() function to send query.

Author: Vlad Lesin
Revision Date: 2014-02-02 20:31:50 UTC

Bug #1268735 fixing is merged from 5.5.

The difference between 5.5 and this patches is the following:

      if (is_network_error(mysql_errno(mysql)))
      {
        mi->report(WARNING_LEVEL, mysql_errno(mysql),
                   "SET @master_heartbeat_period to master failed with error: %s",
                   mysql_error(mysql));
        mysql_free_result(mysql_store_result(mysql));
        goto network_err;
      }
- else if (!check_io_slave_killed(mi->io_thd, mi, NULL)) {
+ else {
        errmsg= "The slave I/O thread stops because SET @master_heartbeat_period "
          "on master failed.";
        err_code= ER_SLAVE_FATAL_ERROR;
        sprintf(err_buff, "%s Error: %s", errmsg, mysql_error(mysql));
        mysql_free_result(mysql_store_result(mysql));
        goto err;
      }

The initial code checked if the slave thread was killed in the case if there
was error in mysql_real_query(). To save this logic non-network error in
mysql_real_query() is treated as fatal error only if the slave thread was
not killed in 5.5. But as 5.6 upstream fix (see upstream revno: 2661.723.1)
does not contain this check it was decided do not include it in PS-5.6.

Revision Date: 2013-11-13 23:49:54 UTC

Bug #1227240 fix.

my.cnf can contain innodb_log_arch_dir option for server. xtrabackup can
use servers my.cnf. As innodb_log_arch_dir option can be used only for backup
preparing xtrabackup exits with error message in the case of backup with
innodb_log_arch_dir option. Such behavior does not allow to make backup if
default my.cnf contains innodb_log_arch_dir.

This fix ignores --innodb_log_arch_dir and --to-archived-lsn and outputs warning
if --prepare is not set.

Fast fix for bug #1156368.

The limit for max captured packet is currently defined in the code.
This limit checking adds some insurance that pcap packet was parsed
right. I think more flexible approach would be in letting this parameter
be a command line option.

Author: Vlad Lesin
Revision Date: 2013-08-07 06:03:17 UTC

Merged with mysql-5.5.33. Revision 4397 of lp:mysql-server/5.5 contains
partial fix for bug 1049871 / CVE-2012-4414. The fix is for the following
issue: "A long SET expression in LOAD DATA is incorrectly truncated when
written to the binary log."

When SET clauses are specified as a part of LOAD DATA statement, these SET
clause user command strings need to be stored as it is inorder to reconstruct
the original user command. These strings are stored as a part of SET clause item
tree's top most Item node's name itself, but Item::name can be of MAX_ALIAS_NAME
size.

Percona's fix just removes limit for Item::name but upstream fix uses new
String list to store the SET expression values.

This branch contains Percona's fix because upstream's fix cause rpl_mdev382
test failure, i.e. the last argument in SET argiments list is repeated twice
in binlog. This is an example from rpl_mdev382 result file diff:

As the number of open tables is increased, table lookup
(testing if a table is already open) and (in particular)
the case when a table is not open, became increasingly more
expensive.

The problem was caused by the open table lookup mechanism,
which was based on traversing a linked list comparing the
file names.

As the list was replaced by a hash table, the lookup
time dropped significantly when used on systems with
a large number of open tables.

The bug #801989 fix.

The main idea of this fix is to return "true" on success and "false" otherwise
from os_file_set_nocache(). That allows to process O_DIRECT flag setting failures.

If setting O_DIRECT failes on log files the srv_unix_file_flush_method is set
to SRV_UNIX_O_DIRECT value to do fsync() on log files. If O_DIRECT fails on
other files the error is ignored to do buffered I/O on filesystems that do not
support direct I/O(for example tmpfs).
