executing
The problem is that mysql lacks information about the objects a view
depends on so it can't dump views and tables in the proper order.
Thus it needs to create "stand-in" myisam tables for each view while
dumping the tables that it later drops and replaces with the actual view
view definition.
But since views can have much more columns than an actual table creating
these stand-in tables may be problematic.
There's no way to portably find out how many columns an mysiam table
can have. It's a complicated formula depending on internal server constants.
Thus we can't have a reliable error check without repeating the logic and
the formula inside mysqldump.
1. Changed the type of the columns of the stand-in tables mysqldump
makes to satisfy view dependencies from the original type to smallint
to save on row space.
2. Added a warning on the mysqldump's standard error for a possible
problems replaying the dump file if the columns of a view exceed 1000.
3. Added a test case.
CAUSES RESTORE PROBLEM
Merging the fix from mysql-5.1 to mysql-5.5
mysql-test/t/mysqldump.test:
There is a difference in the testcase which is added as
part of this fix, when compared with mysql-5.1. In mysql-5.5
and mysql-5.6, "DROP mysql database" fails by enabling
logging, hence removed those lines.
CAUSES RESTORE PROBLEM
Problem Statement:
------------------
mysqldump is not having the dump stmts for general_log and slow_log
tables. That is because of the fix for Bug#26121. Hence, after
dropping the mysql database, and applying the dump by enabling the
logging, "'general_log' table not found" errors are logged into the
server log file.
Analysis:
---------
As part of the fix for Bug#26121, we skipped the dumping of tables
for general_log and slow_log, because the data dump of those tables
are taking LOCKS, which is not allowed for log tables.
Fix:
----
We came up with an approach that instead of taking both meta data
and data dump information for those tables, take only the meta data
dump which doesn't need LOCKS.
As part of fixing the issue we came up with below algorithm.
Design before fix:
1) mysql database is having tables like db, event,... general_log,
... slow_log...
2) Skip general_log and slow_log while preparing the tables list
3) Take the TL_READ lock on tables which are present in the table
list and do 'show create table'.
4) Release the lock.
Design with the fix:
1) mysql database is having tables like db, event,... general_log,
... slow_log...
2) Skip general_log and slow_log while preparing the tables list
3) Explicitly call the 'show create table' for general_log and
slow_log
3) Take the TL_READ lock on tables which are present in the table
list and do 'show create table'.
4) Release the lock.
While taking the meta data dump for general_log and slow_log the
"CREATE TABLE" is replaced with "CREATE TABLE IF NOT EXISTS".
This is because we skipped "DROP TABLE" for those tables,
"DROP TABLE" fails for these tables if logging is enabled.
Customer is applying the dump by enabling logging so, if the dump
has "DROP TABLE" it will fail. Hence, removed the "DROP TABLE"
stmts for those tables.
After the fix we could observe "Table 'mysql.general_log'
doesn't exist" errors initially that is because in the customer
scenario they are dropping the mysql database by enabling the
logging, Hence, those errors are expected. Once we apply the
dump which is taken before the "drop database mysql", the errors
will not be there.
client/mysqldump.c:
In get_table_structure() added code to skip the DROP TABLE stmts for general_log
and slow_log tables, because when logging is enabled those stmts will fail. And
replaced CREATE TABLE with CREATE IF NOT EXISTS for those tables, just to make
sure CREATE stmt for those tables doesn't fail since we removed DROP stmts for
those tables.
In dump_all_tables_in_db() added code to call get_table_structure() for
general_log and slow_log tables.

- mysql-test-run.pl --valgrind complains when all tests succeed.
- perfschema.all_instances fail on non-linux, where ENABLE_TEMP_POOL
is not set and therefore BITMAP mutex is not used.
- MDEV-132: main.mysqldump fails because it depends on exact size of stdio
buffers.
- MDEV-99: rpl.rpl_cant_read_event_incident fails due to a race where the
slave manages to connect while the test case is in the middle of setting up
the master, causing the slave to replicate extra/wrong events.
- MDEV-133: rpl.rpl_rotate_purge_deadlock fails because it issues a
DEBUG_SYNC SIGNAL immediately followed by RESET; this means that sometimes
the intended receipient has no time to see the signal before it is cleared
by the RESET, causing wait to timeout.
routines.
mysqldump in xml mode did not dump routines, events or
triggers.
This patch fixes this issue by fixing the if conditions
that disallowed the dump of above mentioned objects in
xml mode, and added the required code to enable dump
in xml format.
client/mysqldump.c:
BUG#11760384 - 52792: mysqldump in XML mode does not dump

--FLUSH-LOG BREAKS CONSISTENCY
The transaction started by mysqldump gets committed
implicitly when flush-log is specified along with
single-transaction option, and hence can break
consistency.
This is because, COM_REFRESH is executed in order
to flush logs and starting from 5.5 this command
performs an implicit commit.
Fixed by making sure that COM_REFRESH is executed
before the transaction has started and not after it.
Note : This patch triggers following behavioral
changes in mysqldump :
1) After this patch we no longer flush logs before
dumping each database if --single-transaction
option is given like it was done before (in the
absence of --lock-all-tables and --master-data
options).
2) Also, after this patch, we start acquiring
FTWRL before flushing logs in cases when only
--single-transaction and --flush-logs are given.
It becomes safe to use mysqldump with these two
options and without --master-data parameter for
backups.
client/mysqldump.c:
Bug#12809202 61854: MYSQLDUMP --SINGLE-TRANSACTION
--FLUSH-LOG BREAKS CONSISTENCY
Added logic to make sure that, if flush-log option
is specified, mysql_refresh() is never executed after
the transaction has started.
Added verbose messages for all the executions of
mysql_refresh() in order to track its invocation.

This fixes a bug that when you use mysqldump --no-create-info to generate a dump that you want to merge with an existing table,
you can get an innodb table with duplicated unique keys.
Patch orignally by Eric Bergen.
client/mysqldump.c:
Only use UNIQUE_CHECKS=0 for tables that are created.
This solves the issue that you can't get duplicate unique keys when merging two dumps.

("-") IN DATABASE NAMES IN ALTER DATABASE.
mysqldump did not quote database name in 'ALTER DATABASE'
statements in its output. This can further cause a failure
while loading if database name contains a hyphen '-'.
This happened as, while printing the 'ALTER DATABASE'
statements, the database name was not quoted.
Fixed by quoting the database name.

"set optimizer_switch to e or d causes invalid memory writes/valgrind warnings":
due to prefix support, the argument "e" was overwritten with its full value
"engine_condition_pushdown", which caused a buffer overrun.
This was wrong usage of find_type(); other wrong usages are fixed here too.
Please start reading with the comment of typelib.c.
client/mysqldump.c:
A bug: find_type() expects a bitmap as 3rd argument
(each bit is a flag controlling a behaviour of the function);
here it was instead passed the length of the string to search!
That could give random behaviour of find_type()
depending on the string.
We rather need to pass a correct flag to find_type().
The correct flag is FIND_TYPE_BASIC (0).
Flag 8 is not needed as buff cannot have a comma (see how buff is filled).
Flag 1 looks like a superfluous restriction.
Flag 4 is not user-friendly (why use
--compatible=2 rather than --compatible=mysql40 ?, and
we probably not commit to "2" always meaning "mysql40"
until the end of times).
include/mysql.h.pp:
This isn't a problematic API change as we go from char* to const char*:
existing code will run unchanged.
include/typelib.h:
named constants. Not an enum to not significantly change
the declaration of find_type() which would be an API change
(typelib.h is included in mysql.h).
mysql-test/r/mysqldump.result:
correct result (see the two requested modes in SQL_MODE)
mysql-test/suite/sys_vars/t/optimizer_switch_basic.test:
test for BUG#59894. The second SET used to crash.
mysql-test/t/mysqldump.test:
we had no test for multiple modes in --compatible, which is
supported according to --help
mysys/typelib.c:
Fix for BUG#59894. parse_name() is asked to match "e" with a row
of the TYPELIB (the TYPELIB lists permitted flags of optimizer_switch;
and comes from optimizer_switch_names[] of sys_vars.cc).
find_type() is capable of supporting prefixes, but if it is not
passed flag 2 in third argument, it will overwrite its first
argument (the string to search for) with the complete name,
here overwriting "e" with "engine_condition_pushdown". But
as this "e" was a buffer allocated in an Item, it was not big
enough to host the longer name, thus the crash.
We don't need to know the complete flag's name; the output used
from find_type() is just the flag's number (== function's return
code). So we can pass flag 2 to find_type() in parse_name().
After doing this fix and the other fixes in this patch, all usages
of find_type() were using flag 2; in most usages the string to search for,
is not guaranteed to be long enough to host the complete name
(it is either directly from argv, or from alloc_root/my_malloc
done in an earlier call).
Thus, flag 2 is here made implicit: callers need not pass it anymore,
it is always automatically turned on.
This allows to eliminate an oddity: parse_name() took a const char**,
and then removed "const" before calling find_type(), which could
theoretically modify the pointed data, thus lying on constness.
Last, constants for find_type() are now named.
sql-common/client.c:
Two bugs:
1) The enum was not in sync with the array (due to a bad porting of WL 1054;
the extra OPT_ values are about options present in 5.1 and deleted in 5.5);
added a compile_time_assert() to make sure this doesn't happen again
2) find_type() was writing past the end of opt_arg; as opt_arg was allocated
with alloc_root() with no extra space, this was an overrun; it could be seen
when
** building with -DWITH_VALGRIND -DHAVE_purify -DEXTRA_DEBUG
** making execution go through the faulty code; this faulty
code is executed only if the client asks to read a configuration
file like this:
mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "/tmp/cnf.cnf");
so by adding such line to the start of mysql_client_test.c::client_connect(),
we could see the valgrind warning:
==30548== Invalid write of size 1
==30548== at 0x4C2624C: strcpy (mc_replace_strmem.c:303)

This is fixed by having find_type() not overwrite anymore.

When mysqldump tries to dump information in xml format,
the result does not contain field level comments.
In order to retrieve various informations for a field/column,
mysqldump currently uses 'show fields from <tab>' statement.
The attributes returned by the statement lacks the information
regarding field comments.
Fixed by changing the query to one that probes I_S to retrieve
required field informations, including the field comment.
client/mysqldump.c:
Bug#13618 : mysqldump --xml omits comment on table field.
Replaced the 'show fields' command by a statement that
queries I_S, in order to retrieve information on all the
attributes that 'show fields' returns along-with an additional
column_comment information.

and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
- Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id
- Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
- Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.

- This fixes a rase condition when two threads calls external lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
Store latest transaction id in controll file if recovery was done.
- This allows one to run maria_chk on an automatcally recovered tables without warnings about too small transaction id

storage/maria/ma_open.c:
Ensure we call _ma_block_get_status_no_versioning() for transactional tables without versioning (like tables with fulltext)
storage/maria/ma_pagecache.c:
Allow one to flush blocks that are pinned for read.
This fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
storage/maria/ma_recovery.c:
Set maria_recovery_changed_data to 1 if recover changed something.
Set max_trid_in_control_file to max found trn if we found a bigger trn.
The allows will ensure that the control file is up to date after recovery which allows one to run maria_chk on the tables without warnings about too big trn
storage/maria/ma_state.c:
Call maria_create_trn_hook() in _ma_setup_live_state() instead of ha_maria::external_lock()
This ensures that 'state' and trn are in sync and thus fixes the race condition mentioned for ha_maria.cc
storage/maria/ma_static.c:
Added maria_create_trn_hook() and maria_recovery_changed_data
storage/maria/maria_def.h:
Added MARIA_HANDLER->external_ptr, which is used to hold MariaDB thd.
Added some new external variables
Removed reference to non existing function: maria_concurrent_inserts()

to string conversions and vice versa"
Initial import of the dtoa.c code and custom wrappers around it
to allow its usage from the server code.
Conversion of FLOAT/DOUBLE values to DECIMAL ones or strings
and vice versa has been significantly reworked. As the new
algoritms are more precise than the older ones, results of such
conversions may not always match those obtained from older
server versions. This in turn may break compatibility for some
applications.
This patch also fixes the following bugs:
- bug #12860 "Difference in zero padding of exponent between
Unix and Windows"
- bug #21497 "DOUBLE truncated to unusable value"
- bug #26788 "mysqld (debug) aborts when inserting specific

Bug#35297 SHOW CREATE EVENT does not show the DEFINER:
update test result after a merge from now.
DECIMAL and TIMESTAMP used to have NUM_FLAG, but NEWDECIMAL was forgotten.
It's correct that TIMESTAMP does not have the flag nowadays (manual will be updated, connectors
developers will be notified).
client/mysqldump.c:
IS_NUM_FIELD(f) removed and replaced by its definition (f>flags & NUM_FLAG).
include/mysql.h:
- IS_NUM_FIELD() is removed because name is too close to IS_NUM() and it is not used a lot
- INTERNAL_NUM_FIELD() is removed:
* it forgets to test NEWDECIMAL (when IS_NUM() was updated for NEWDECIMAL we forgot
to update INTERNAL_NUM_FIELD()), that's why client didn't mark NEWDECIMAL with NUM_FLAG (a bug).
* it has an obsolete test for length of the TIMESTAMP field: test became accidentally wrong when length
of TIMESTAMP was changed to always be 19 (when the format was changed from YYYYMMDDhhmmss to
YYYY-MM-DD hh:mm:ss), never 8 or 14 anymore. That obsolete test caused TIMESTAMP to lose NUM_FLAG,
which was an accidental but good change (see below).
* IS_NUM() should be used instead
- IS_NUM(f) is changed: TIMESTAMP used to be parsable as a number without quotes (when it was formatted as
"YYYYMMDDhhmmss"); but it is not anymore (now that it is "YYYY-MM-DD hh:mm:ss"), so it should not have NUM_FLAG
(mysqldump needs to quote TIMESTAMP values), so IS_NUM() should return false for it.

when used with --tab
1) New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE).
mysqldump is updated to use this in --tab mode.
2) ESCAPED BY/ENCLOSED BY field parameters are documented as
accepting CHAR argument, however SELECT .. INTO OUTFILE
silently ignored rests of multisymbol arguments.
For the symmetrical behavior with LOAD DATA INFILE the
server has been modified to fail with the same error:
ERROR 42000: Field separator argument is not what is
expected; check the manual
3) Current LOAD DATA INFILE recognizes field/line separators
"as is" without converting from client charset to data
file charset. So, it is supposed, that input file of
LOAD DATA INFILE consists of data in one charset and
separators in other charset. For the compatibility with
that [buggy] behaviour SELECT INTO OUTFILE implementation
has been saved "as is" too, but the new warning message
has been added:
Non-ASCII separator arguments are not fully supported
This message warns on field/line separators that contain
non-ASCII symbols.
client/mysqldump.c:
mysqldump has been updated to call SELECT ... INTO OUTFILE
statement with a charset from the --default-charset command
line parameter.

Added test case for bug #30946.
sql/field.cc:
String conversion code has been moved from check_string_copy_error()
to convert_to_printable() for reuse.
sql/share/errmsg.txt:
New WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED message has been added.
sql/sql_class.cc:
The select_export::prepare() method has been modified to:
1) raise the ER_WRONG_FIELD_TERMINATORS error on multisymbol
ENCLOSED BY/ESCAPED BY field arguments like LOAD DATA INFILE;
2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message on non-ASCII field or line separators.
The select_export::send_data() merhod has been modified to
convert item data to output charset (see new SELECT INTO OUTFILE
syntax). By default the BINARY charset is used for backward
compatibility.
sql/sql_class.h:
The select_export::write_cs field added to keep output
charset.
sql/sql_load.cc:
mysql_load has been modified to warn on non-ASCII field or
line separators with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message.
sql/sql_string.cc:
New global function has been added: convert_to_printable()
(common code has been moved from check_string_copy_error()).
sql/sql_string.h:
New String::is_ascii() method and new global convert_to_printable()
function have been added.
sql/sql_yacc.yy:
New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE). By default the BINARY charset is used for
backward compatibility.
mysqldump --tab still dumped triggers to stdout rather than to
individual tables.
We now append triggers to the .sql file for the corresponding
table.
--events and --routines correspond to a database rather than a
table and will still go to stdout with --tab unless redirected
with --result-file (-r).
client/mysqldump.c:
Extend open_sql_file_for_table() so we can open-append.
Change dump_triggers_for_table() so it will append its
output to the table's .sql-file when --tab is used.
mysql-test/r/mysqldump.result:
Show that when using --tab, triggers now end up in the .sql
file with the corresponding table (after that table), while
--routines and --events go to stdout or --result-file.
mysql-test/t/mysqldump.test:
Show that when using --tab, triggers now end up in the .sql
file with the corresponding table (after that table), while
--routines and --events go to stdout or --result-file.
