prevent concurrent cleanups in multi-threaded mysqlimport
(they can happen if many threads get an error at the same time),
safe_exit() is not thread-safe.
MYSQLADMIN -U ROOT -P
DESCRIPTION
===========
Crash occurs when no command is given while executing
mysqladmin utility.
ANALYSIS
========
In mask_password() the final write to array 'temp_argv'
is done without checking if corresponding index 'argc'
is valid (non-negative) or not. In case its negative
(would happen when this function is called with 'argc'=0),
it may cause a SEGFAULT. Logically in such a case,
mask_password() should not have been called as it would do
no valid thing.
FIX
===
mask_password() is now called after checking 'argc'. This
function is now called only when 'argc' is positive
otherwise the process terminates
MULTIPLE THREADS
Description:- The utility "mysqlimport" does not use
multiple threads for the execution with option
"--use-threads". "mysqlimport" while importing multiple
files and multiple tables, uses a single thread even if the
number of threads are specified with "--use-threads" option.
Analysis:- This utility uses ifdef HAVE_LIBPTHREAD to check
for libpthread library and if defined uses libpthread
library for mutlithreaing. Since HAVE_LIBPTHREAD is not
defined anywhere in the source, "--use-threads" option is
silently ignored.
Fix:- "-DTHREADS" is set to the COMPILE_FLAGS which will
enable pthreads. HAVE_LIBPTHREAD macro is removed.
As the MF_THREAD_SPECIFIC was introduced to the alloc_root's and
the prealloc added to the statement::mem_root and statement::result.alloc, we have to adjust
the embedded server to it. The preallocation was removed for the embedded server as it
makes no sence for it. The msyqltest should free the statement inside the proper thead to
make the memory statistics happy.
Description:- mysqlslap is a diagnostic utility designed to
emulate client load for a MySQL server and to report the
timing of each stage. This utility crashes when invalid
values are passed to the options 'num_int_cols_opt' or
'num_chars_cols_opt' or 'engine'.
Analysis:- mysqlslap uses "parse_option()" to parse the
values specified to the options 'num_int_cols_opt',
'num_chars_cols_opt' and 'engine'. These options takes
values separated by commas. In "parse_option()", the comma
separated values are separated and copied into a buffer
without checking the length of the string to be copied. The
size of the buffer is defined by a macro HUGE_STRING_LENGTH
whose value is 8196. So if the length of the any of the
comma separated value exceeds HUGE_STRING_LENGTH, will
result in a buffer overflow.
Fix:- A check is introduced in "parse_option()" to check
whether the size of the string to be copied is more than
HUGE_STRING_LENGTH. If it is more, an error, "Invalid value
specified for the option 'xxx'" is thrown.
Option length was incorrectly calculated for the last comma
separated value. So fixed that as well.
mysqldump now attempts to make use of the INFORMATION_SCHEMA tables.
If the table name is not found with a case sensitive search, it
fallbacks to a case insensitive search.
Part 1: first 2 cases of valgrind complain. context_analysis_only can be used on non-started LEX (opening tables)
obviouse fixes in DBUG and is_lex_started assignment.
in when using vio->read_timeout (and write_timeout) to set
timeouts of a new vio, as in:
vio_timeout(vio, 0, old_vio.read_timeout)
vio_timeout(vio, 0, old_vio.write_timeout)
remember that timeouts are stored in ms, but vio_timeout()'s
argument is in seconds.
Change mysqlcheck option to upgrade-views={NO,YES,FROM_MYSQL}
mysql_upgrade now runs upgrade-views=yes to perform a checksum of all
views and add mariadb-version by default. upgrade-views=from_mysql if
MySQL is detected as teh origin version.
Allow tables and views to be repaired in same command.
Make error messages represent if it is a REPAIR TABLE or REPAIR VIEW
Honor write_binlog even for REPAIR VIEW .. FROM MYSQL
opt_all_in_1 does a list of REPAIR TABLE and a list of REPAIR VIEW
If a table list is passes this is corrected with the right command
Add static vars on phases to make merging consistent.

Removed 'galera-sst-mode' option from mysqldump and added logic

donor node and send it to the joiner node.
partially cherry-pick from mysql/5.6.
No test case (mysql/5.6 test case is useless, the correct
test case uses too much memory)
