Backport the fix to 5.5, because it fails there too
The patch fixes two test failures:
- on slow builders, sometimes a connection attempt which should
fail due to the exceeded number of thread_pool_max_threads
actually succeeds;
- on even slow builders, MTR sometimes cannot establish the
initial connection, and check-testcase fails prior to the
test start
The problem with check-testcase was caused by connect-timeout=2
which was set for all clients in the test config file. On slow
builders it might be not enough.
There is no way to override it for the pre-test check, so it needed
to be substantially increased or removed.
The other problem was caused by a race condition between sleeps
that the test performs in existing connections and the connect
timeout for the connection attempt which was expected to fail.
If sleeps finished before the connect-timeout was exceeded, it
would allow the connection to succeed.
To solve each problem without making the other one worse,
connect-timeout should be configured dynamically during the test.
Due to the nature of the test (all connections must be busy
at the moment when we need to change the timeout, and cannot execute
SET GLOBAL ...), it needs to be done independently from the server.
The solution:
- recognize 'connect_timeout' as a connection option in mysqltest's
"connect" command;
- remove connect-timeout from the test configuration file;
- use the new connect_timeout option for those connections which
are expected to fail;
- re-arrange the test flow to allow running a huge SLEEP
without affecting the test execution time (because it would be
interrupted after the main test flow is finished).
The test is still subject to false negatives, e.g. if the connection
fails due to timeout rather than due to the exceeded number of
allowed threads, or if the connection on extra port succeeds due
to a race condition and not because the special logic for the extra
port. But those false negatives have always been possible there
on slow builders, they should not be critical because faster builders
should catch such failures if they appear.

mysqldump/mysql_install_db.exe fail
The bug is described in
https://connect.microsoft.com/VisualStudio/Feedback/Details/1902345
When reading from a pipe in text mode, using CRT function such as fread(),
some newlines may be lost. Workaround is to use binary mode on reading side
and if necessary, replace \r\n with \n.
Add some event types for the compressed event, there are:
QUERY_COMPRESSED_EVENT,
WRITE_ROWS_COMPRESSED_EVENT_V1,
UPDATE_ROWS_COMPRESSED_EVENT_V1,
DELETE_POWS_COMPRESSED_EVENT_V1,
WRITE_ROWS_COMPRESSED_EVENT,
UPDATE_ROWS_COMPRESSED_EVENT,
DELETE_POWS_COMPRESSED_EVENT.
These events inheritance the uncompressed editor events. One of their constructor functions and write
function have been overridden for uncompressing and compressing. Anything but this is totally the same.
On slave, The IO thread will uncompress and convert them When it receiving the events from the master.
So the SQL and worker threads can be stay unchanged.
Now we use zlib as compress algorithm. It maybe support other algorithm in the future.
RUNNING FIREWALL
mysqladmin shutdown will try to extract the server's pid file before executing
the actual shutdown command.
It will do that by executing a SHOW VARIABLES query and processing the result.
However if that query fails it print a (somewhat confusing) error mesasage
and will still continue to do the shutdown command.
If that passes then the mysqladmin user will get an error but the shutdown will
still be successful.
This is confusing so the error message text is changed to say that this is a
non-fatal error and execution continues.
No test case added since it'd require a selective query failure device that's
not available in 5.5.
The issue was that when running with valgrind the wait for master_pos_Wait()
was not long enough.
This patch also fixes two other failures that could affect rpl_mdev6020:
- check_if_conflicting_replication_locks() didn't properly check domains
- 'did_mark_start_commit' was after signals to other threads was sent which could
get the variable read too early.
a correct fix:
* store properly quoted table names in tables4repair/etc lists
* tell handle_request_for_tables whether the name is aalready properly quoted
* test cases for all uses of fix_table_name()
It happens when you are trying to read two or more log files from a
remote server using mysqlbinlog utility.
The reason for this is no matching mysql_close() that concludes the
life time of 'mysql' struct describing connection to the server.
This happens when mysqlbinlog is invoked with connecting to the server
and requesting more than one binlog file. In such case
dump_remote_log_entries() keeps calling safe_connect() per eachfile,
never caring to invoke mysql_close(). Only the final safe_connect()'s
allocation effect are cleaned by the base code.
That is with 2 files there's one 'mysql' connection descriptor struct
uncleaned/deallocated.
We are backporting the bug 21255763 (pushed in mysql-trunk)
in the earlier version of MySQL starting from 5.5 to 5.7.
which was pushed in mysql-trunk.
Fix:
Invoke mysql_close() just before mysql_init() in safe_connect()
defined in mysqlbinlog.cc. That makes possibly previously used 'mysql' be
reclaimed prior a new one is allocated.
`--help` is a perfectly valid parameter and both `mysqladmin` and
`mysql_waitpid` should exit with success (zero errror code).

ERROR MESSAGE
Description:- Mtr test, "main.mysqldump" is failing with an
assert when "mysqlimport" client utility is executed with
the option "--use_threads".
Analysis:- "mysqlimport" uses the option, "--use_threads",
to spawn worker threads to complete its job in parallel. But
currently the main thread is not waiting for the worker
threads to complete its cleanup, rather just wait for the
worker threads to say its done doing its job. So the cleanup
is done in a race between the worker threads and the main
thread. This lead to an assertion failure.
Fix:- "my_thread_join()" is introduced in the main thread to
join all the worker threads it have spawned. This will let
the main thread to wait for all the worker threads to
complete its cleanup before calling "my_end()".
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

An addition to original patch:
- use FN_REFLEN instead of HOST_NAME_MAX (the latter can be undefined)
- avoid calling gethostname() on every prompt construction by caching it
Introduce `\H` option which behaves mostly like `\h`. The only exception is
when the client connects to the server hosted on localhost. In this case, the
hostname will be used instead.
- Removed some QQ markers
- Removed some rows not compatible with valgrind 3.9.0
- Made mysql_install_db.sh more silent by default. --verbose now gives more information
- Added assert that auto-increment doesn't generate 0 (safety)
- Removed thd->set_time() in some places as it's set in init_for_queries()
- Fixed some --big tests in tokudb
- Fixed a bug in mysql_client_test.cc where sql_mode was not properly reset
mysql.cc:
Unlike the main MYSQL structure, kill_mysql did not have MYSQL_OPT_PROTOCOL set.
Move all connection-related settings to a separate function and

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
The following left in semi-improved state to keep patch size reasonable:

While querying INFORMATION SCHEMA, check for a table's engine
only used table name, but not schema name; so, if there were different
rows with the same table name, a wrong one could be retrieved.
The result of the check affected the decision whether the contents
of the table should be dumped, and whether a DELAYED option can be used.
Fixed by adding a clause for table_schema to the query.

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.
There are three Log_event::read_log_event() methods:
1. read the event image from IO_CACHE into String
2. create Log_event from the in-memory event image
3. read the event image from IO_CACHE and create Log_event
The 3rd was reading event image into memory and invoking the 2nd to
create Log_event. Now the 3rd also uses the 1st to read the event image
from IO_CACHE into memory, instead of duplicating its functionality.
- If run with valgrind, mysqltest will now wait longer when syncronizing slave with master
- Ensure that we wait with cleanup() until slave thread has stopped.
- Added signal_thd_deleted() to signal close_connections() that all THD's has been freed.
- Check in handle_fatal_signal() that we don't use variables that has been freed.
- Increased some timeouts when run with --valgrind
Other things:
- Fixed wrong test in one_thread_per_connection_end() if galera is used.
- Removed not needed calls to THD_CHECK_SENTRY() when we are calling 'delete thd'.

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.

remember that timeouts are stored in ms, but vio_timeout()'s

Change mysqlcheck option to upgrade-views={NO,YES,FROM_MYSQL}

Problem: For every event read, mysqlbinlog calls localtime() which in turn
calls stat(/etc/localtime) which is causing kernel mutex contention.
Analysis and Fix:
localtime() calls stat(/etc/localtime) for every instance of the call
where as localtime_r() the reentrant version was optimized to store
the read only tz internal structure. Hence it will not call
stat(/etc/localtime). It will call only once at the beginning.
The mysql server is calling localtime_r() and mysqlbinlog tool is
one place where we are still using localtime().
Once the process (mysqlbinlog) is started if timezone is changed
it will be not picked up the the process and it will continue
with the same values as the beginning of the process. This
behavior is in-lined with mysql server.
Also adding localtime_r() and gmtime_r() support for windows.

mysqlimport had code for multi-threaded import. By mistake it was disabled for
many years, at least since 5.5 (more likely even in 5.1), but mysqlimport happily
accepted (and ignored) --use-threads option ever since.
After Mroonga merge HAVE_LIBPTHREAD became defined and multi-threaded import
suddenly came to life. As it exit() the program brutally on any error (never mind
that some import threads may be running) mysys rightfully complains. Safemalloc
complains too in debug builds.
Fix: don't try a clean exit on an error, don't shutdown mysys and tell safemalloc
to shut up. Yes, and remove #ifdef HAVE_LIBPTHREAD, since 5.5 the client library
is always multi-threaded.

The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare
identically was seen as different strings. (Space was handled correctly, but not NBSP)
This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by.
Fixed by removing all characters that compares as end space when creating a hash.
Other things:
- Fixed that --sorted_results also works for errors in mysqltest.
- Speed up hash by not comparing strings that has different hash.
- Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers.
This was previously done for some functions, but not for all.
- Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.

fix readline/libedit detection:
* search in readline/, editline/ and edit/readline/
* fix typos CMAKE_REQUIRES_LIBRARIES -> CMAKE_REQUIRED_LIBRARIES
* use correct libedit API
* use different cmake variables for libedit and readline
Merged lp:maria/maria-10.0-galera up to revision 3880.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.

mysqldump:
- Added --log-queries to allow one to disable logging for the dump
sql/log_event.cc:
- Removed setting of enable_slow_log as it's not required anymore.
sql/sql_parse.cc:
- Set enable_slow_log to value of thd->variables.sql_log_slow as this will speed up tests if slow log is disabled.
- opt_log_slow_admin_statements can now only disable slow log, not enable it.
sql/sql_explain.cc:
- Minor cleanup
Other things:
- Added sql_log_slow to system variables.
- Changed opt_slow_log to global_system_variables.sql_log_slow in all files
- Updated tests to reflect changes
