There were two newly enabled warnings:
1. cast for a function pointers. Affected sql_analyse.h, mi_write.c
and ma_write.cc, mf_iocache-t.cc, mysqlbinlog.cc, encryption.cc, etc
2. memcpy/memset of nontrivial structures. Fixed as:
* the warning disabled for InnoDB
* TABLE, TABLE_SHARE, and TABLE_LIST got a new method reset() which
does the bzero(), which is safe for these classes, but any other
bzero() will still cause a warning
* Table_scope_and_contents_source_st uses `TABLE_LIST *` (trivial)
instead of `SQL_I_List<TABLE_LIST>` (not trivial) so it's safe to
bzero now.
* added casts in debug_sync.cc and sql_select.cc (for JOIN)
* move assignment method for MDL_request instead of memcpy()
* PARTIAL_INDEX_INTERSECT_INFO::init() instead of bzero()
* remove constructor from READ_RECORD() to make it trivial
* replace some memcpy() with c++ copy assignments
- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)
- Also fix printf-format warnings
Make the above mentioned warnings fatal.
- fix pthread_join on Windows to set return value.
- Removing the "diff_if_only_endspace_difference" argument from
MY_COLLATION_HANDLER::strnncollsp(), my_strnncollsp_simple(),
as well as in the function template MY_FUNCTION_NAME(strnncollsp)
in strcoll.ic
- Removing the "diff_if_only_space_different" from ha_compare_text(),
hp_rec_key_cmp().
- Adding a new function my_strnncollsp_padspace_bin() and reusing
it instead of duplicate code pieces in my_strnncollsp_8bit_bin(),
my_strnncollsp_latin1_de(), my_strnncollsp_tis620(),
my_strnncollsp_utf8_cs().
- Adding more tests for better coverage of the trailing space handling.
- Removing the unused definition of HA_END_SPACE_ARE_EQUAL

Base code and idea from a patch from by plinux at Taobao.
The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC.
Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc().
There are plenty of new asserts to ensure that for a debug server the counting is correct.
Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS.
- The later is there mainly to show how query is progressing.
The following changes in interfaces was needed to get this to work:
- init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root()
- my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC
- Added flag for hash_init() so that one can mark hash table to be thread specific.
- Added flags to init_tree() so that one can mark tree to be thread specific.
- Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG.
- Added flag to Warning_info::Warning_info() if the structure should be fully initialized.
- String elements can now be marked as thread specific.
- Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC.
- Changed type of myf from int to ulong, as this is always a set of bit flags.
Other things:
- Removed calls to net_end() and thd->cleanup() as these are now done in ~THD()
- We now also show EXAMINED_ROWS in SHOW PROCESSLIST
- Added new variable 'memory_used'
- Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory.
- Removed calls to the obsoleted function init_dynamic_array()
- Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...)

Problem:-
In case of blob data field, UNION ALL doesn't give correct result.
Analysis:-
In MyISAM table, when we dont want to check for the distinct for particular
key, we set the key_map to zero.
While writing record in MyISAM table, we check the distinct with the help
of keys, by checking whether that key is active in key_map and then writing
the record.
In case of blob field, we are checking for distinct by unique constraint,
where we are not checking whether that unique key is active or not in key_map.
Solution:
Before checking for distinct, check whether any key is active in key_map.
storage/myisam/mi_write.c:

consistent with mi_write();
- always use keyinfo->ck_delete()/ck_insert() instead of _mi_ck_delete()/_mi_ck_write()
to handle index properly, as it may be of B-tree or R-tree type.

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.
Note: This patch only removed LGPL licensed files
in MySQL 5.1, and is the second of a set of
patches to remove LGPL from all trees.
(See Bug# 11840513 for details)
and 'THREAD_SAFE_CLIENT'.
As of MySQL 5.5, we no longer support non-threaded
builds. This patch removes all references to the
obsolete THREAD and THREAD_SAFE_CLIENT preprocessor
symbols. These were used to distinguish between
threaded and non-threaded builds.
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
client/mysqldump.c:
Pass my_free directly as its signature is compatible with the
callback type -- which wasn't the case for free_table_ent.

When MyISAM writes newly created index page it may be
initialized partially. In other words some bytes of
sensible data and uninitialized tail of the page may
go into index file.
Under certain rare circumstances these hunks of memory
may contain data that would be otherwise inaccessible
to user, like passwords or data from other tables.
Fixed by initializing memory for temporary MyISAM key
buffer to '\0'.
No test case for this fix as it is heavily covered by
existing tests.
storage/myisam/mi_open.c:
When creating new MI_INFO object, initialize MI_INFO::buff.
This is done to ensure that we never write uninitialized
memory hunks to index file.
storage/myisam/mi_page.c:
No need to silence memory error detector anymore,
page buffer is always initialized.
storage/myisam/mi_write.c:
Fixed invalid memory read of 2 bytes. new_right_length
is length of data on a page, including first 2 bytes
that store this length itself. pos + k_length is pure
data excluding these 2 bytes containing length.
storage/myisam/rt_index.c:
To avoid uninitialized data write, create new page
on info->buff, instead of locally allocated buffer.
Note: second key block on info->buff is used here,
because first block is used by called functions.
storage/myisam/rt_split.c:
To avoid uninitialized data write, create new page
on info->buff, instead of locally allocated buffer.
Add some extra error output and code cleanup in an attempt to fix/debug

- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.
This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.
This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.
* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff

- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements

Added SEARCH_INSERT to be used when inserting new keys
Added SEARCH_PART_KEY for partial searches
Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID

include/my_handler.h:
Make next_flag 32 bit to make sure we can handle all SEARCH_ bits

mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag

Use 'file->start_state' as default state for transactional tables without versioning
At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
Updated comment
