Fixed by deleting the sequence if we where not able to initialize it
I also noticed that we didn't always set the error message when
check_killed(), which could lead to aborted queries without error
beeing properly set. Fixed by default setting error message if
check_error() noticed that killed had been called.
This allowed me to remove a lot of calls to thd->send_kill_message().
Handle string length as size_t, consistently (almost always:))
Change function prototypes to accept size_t, where in the past
ulong or uint were used. change local/member variables to size_t
when appropriate.
This fix excludes rocksdb, spider,spider, sphinx and connect for now.
* get_rec_bits() was always reading two bytes, even if the
bit field contained only of one byte
* In various places the code used field->pack_length() bytes
starting from field->ptr, while it should be field->pack_length_in_rec()
* Field_bit::key_cmp and Field_bit::cmp_max passed field_length as
an argument to memcmp(), but field_length is the number of bits!
Most "new" failures fixed in the following files:
- sql_select.cc
- item.cc
- item_func.cc
- opt_subselect.cc
Other things:
- Allocate udf_handler strings in mem_root
- Required changes in sql_string.h
- Add mem_root as argument to some new [] calls
- Mark udf_handler strings as thread specific
- Removed some comment blocks with code
The issue was that r_loops, r_rows and r_filtered in ANALYZE FORMAT= JSON were not
calculated for the table on which we were performing the MRR scan in the BKA join
Fixed this by adding respective counter in the JOIN_TAB_SCAN_MRR::open and JOIN_TAB_SCAN_MRR::next
- Added sql/mariadb.h file that should be included first by files in sql
directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables
that must be done before my_global.h is included)
- Removed a lot of include my_global.h from include files
- Removed include's of some files that my_global.h automatically includes
- Removed duplicated include's of my_sys.h
- Replaced include my_config.h with my_global.h
Also, implement MDEV-11027 a little differently from 5.5 and 10.0:
recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
Workaround for join_cache + index on vcols + keyread bug.
Initialize the record to avoid caching garbage in non-read fields.
A proper fix (do not cache non-read fields at all) is done in 10.2
in commits 5d7607f340f..8d99166c697
This fixes a bug where handler::read_range_first (for example)
needed to compare vcol values that were not calculated yet.
As a bonus it fixes few cases where vcols were calculated twice
- Part 4: Removing calls to sql_alloc() and sql_calloc()
Other things:
- Added current_thd in some places to make it clear that it's called (easier to remove later)
- Move memory allocation from Item_func_case::fix_length_and_dec() to Item_func_case::fix_fields()
- Added mem_root to some new calls
- Fixed some wrong UNINIT_VAR() calls
- Fixed a bug in generate_partition_syntax() in case of errors
- Added mem_root to argument to new thread_info
- Simplified my_parse_error() call in sql_yacc.yy
- Added mem_root to all calls to new Item
- Added private method operator new(size_t size) to Item to ensure that
we always use a mem_root when creating an item.
This saves use once call to current_thd per Item creation
Avoided exponential recursive calls of JOIN_CACHE::join_records() in the case
of non-nested outer joins.
A different solution is required to resolve this performance problem for
nested outer joins.
The method JOIN_CACHE::init may fail (return 1) if some conditions on the
used join buffer is not satisfied. For example it fails if join_buffer_size
is greater than join_buffer_space_limit. The conditions should be checked
when running the EXPLAIN command for the query. That's why the method
JOIN_CACHE::init has to be called for EXPLAIN commands as well.
This is port of fix for MySQL BUG#17647863.

message:
Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM
Rename test() macro to MY_TEST() to avoid conflict with libc++.
- Run probes like MYSQL_INSERT_SELECT_START or
MYSQL_MULTI_DELETE_START for EXPLAIN, too.
We should run them, because 1. EXPLAIN SELECT does it, and
2. MySQL also does it.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Solaris fixes:
- Fixed that wait_timeout_func and wait_timeout tests works on solaris
- We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
- Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Added missing sync_with_master
Other bug fixes:
- Free memory for rpl_global_gtid_binlog_state before exit() to avoid 'accessing uninitalized mutex' error.
BUILD/FINISH.sh:
Fixed issues on Solaris with ksh
BUILD/compile-solaris-amd64-debug:
Added missing -m64 flag
configure.cmake:
We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO)
mysql-test/suite/rpl/t/rpl_gtid_mdev4473.test:
- Added missing sync_with_master (fix by knielsen)
sql-common/client.c:
Added () to get rid of compiler warning
sql/item_strfunc.cc:
Fixed compiler warning
sql/log.cc:
Free memory for static variable rpl_global_gtid_binlog_state before exit()
- If we are compiling with safemalloc, we would try to call sf_free() for some members after sf_terminate() was called, which would result of trying to access the uninitalized mutex 'sf_mutex'
sql/multi_range_read.cc:
Fixed compiler warnings of converting double to ulong.
sql/opt_range.cc:
Fixed compiler warnings of converting double to ulong or uint
- Better to have all variables that can be number of rows as 'ha_rows'
sql/rpl_gtid.cc:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/rpl_gtid.h:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/set_var.cc:
Fixed compiler warning
sql/sql_join_cache.cc:
Fixed compiler warnings of converting double to uint
sql/sql_show.cc:
Added cast to get rid of compiler warning
sql/sql_statistics.cc:
Remove code that didn't do anything.
(store_record() with record[0] is a no-op)
storage/xtradb/os/os0file.c:
Added __attribute__ ((unused))
support-files/compiler_warnings.supp:
Ignore warnings from atomic_add_64_nv
(was not able to fix this with a cast as the macro is a bit different between systems)
vio/viosocket.c:
Added more DBUG_PRINT
