The order of outputting stored procedures is important. Stored
procedures must be available on view creation, for views which make use
of them. Make sure to print them before outputting tables.
Do not silence uncertain cases, or fix any bugs.
The only functional change should be that ha_federated::extra()
is not calling DBUG_PRINT to report an unhandled case for
HA_EXTRA_PREPARE_FOR_DROP.
While writing comments if database object names has a new
line character, then next line is considered a command, rather
than a comment.
This patch fixes the way comments are constructed in mysqldump.
(cherry picked from commit 1099f9d17b1c697c2760f86556f5bae7d202b444)
MYSQL_OPT_SSL_MODE option introduced.
It is set in case of --ssl-mode=REQUIRED and permits only SSL connection.
(cherry picked from commit 3b2d28578c526f347f5cfe763681eff365731f99)
DESCRIPTION
===========
Buffer overflow is reported in a lot of code sections
spanning across server, client programs, Regex libraries
etc. If not handled appropriately, they can cause abnormal
behaviour.
ANALYSIS
========
The reported casea are the ones which are likely to result
in SEGFAULT, MEMORY LEAK etc.
FIX
===
- sprintf() has been replaced by my_snprintf() to avoid
buffer overflow.
- my_free() is done after checking if the pointer isn't
NULL already and setting it to NULL thereafter at few
places.
- Buffer is ensured to be large enough to hold the data.
- 'unsigned int' (aka 'uint') is replaced with 'size_t'
to avoid wraparound.
- Memory is freed (if not done so) after its alloced and
used.
- Inserted assert() for size check in InnoDb memcached
code (from 5.6 onwards)
- Other minor changes

mysqldump --routine fails to dump databases containing backslash ("\")
character. This happened because escaped database name was being used as an
identifier while changing current database. Such identifers are not supposed
to be escaped, they must be properly quoted instead.
This includes fixing all utilities to not have any memory leaks,
as safemalloc warnings stopped tests from passing on MacOSX.
- Ensure that all clients takes character-set-dir, as the
libmysqlclient library will use it.
- mysql-test-run now passes character-set-dir to all external clients.
- Changed dynstr_free() so that it can be called twice (made freeing code easier)
- Changed rpl_global_gtid_slave_state to be allocated dynamicly as it
includes a mutex that needs to be initizlied/destroyed before my_end() is called.
- Removed rpl_slave_state::init() and rpl_slave_stage::deinit() as
their job are better handling by constructor and delete.
- Print alias instead of table_name in check_duplicate_key as
table_name may have been converted to lower case.
Other things:
- Fixed a case in time_to_datetime_with_warn() where we where
using && instead of & in tests
IMPLEMENTED IN ALL CLIENT PROGRAMS
Description: Option "enable-cleartext-plugin" is not
available for the following client utilities:-
mysqldump
mysqlimport
mysqlshow
mysqlcheck
Analysis: The unavailability of this option limits the
features like PAM authentication from using the above
mentioned utilities.
Fix: Option "enable-cleartext-plugin" is implemented in the
above mentioned client utilities.
~40% bugfixed(*) applied
~40$ bugfixed reverted (incorrect or we're not buggy)
~20% bugfixed applied, despite us being not buggy
(*) only changes in the server code, e.g. not cmakefiles
A new command line option "galera-sst-mode" was introduced
in mysqldump as part of fix for MDEV-6316. But, since the
fix was pushed to maria-10.0-galera branch, the mysqldump
tool supplied with mariadb client deb/rpm packages, does not
have this new opion.
This fix contains the same patch along with a test case.
Mysqldump overflows stack buffer when copying table name from commandline arguments resulting in stack corruption and ability to execute arbitrary code.
Fix: Check length of all positional arguments passed to mysqldump is smaller than NAME_LEN.
Note: Mysqldump heavily depends on that database objects (databases, tablespaces, tables, etc) are limited to small size (now it is 64).

MDEV-6344: mysqldump issues FLUSH TABLES, which gets written into binlog and replicated
Add a --gtid option (for compatibility, the original behaviour is preserved
when --gtid is not used).
With --gtid, --master-data and --dump-slave output the GTID position (the
old-style file/offset position is still output, but commented out). Also, a
CHANGE MASTER TO master_use_gtid=slave_pos is output to ensure a provisioned
slave is configured in GTID, as requested.
Without --gtid, the GTID position is still output, if available, but commented
out.
Also fix MDEV-6344, to avoid FLUSH TABLES getting into the binlog. Otherwise a
mysqldump on a slave server will silently inject a GTID which does not exist
on the master, which is highly undesirable.
Also fix an incorrect error handling around obtaining binlog position with
--master-data (was probably unlikely to trigger in most cases).
do_start_slave_sql() is called from maybe_exit().
We should not recurse when maybe_exit() is called for an error during do_start_slave_sql().
Also remove a meaningless (but safe) "goto err".
- MariaDB-5.5 part of the fix: since we can't easily fix query optimization for I_S tables,
run the affected-tablespaces query with semijoin=off. It happens to have a good query plan
with that setting.
[This is a forward-port to MariaDB 10.0]
