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.
Check whether the master and purge thread are active after creating them. Do
not proceed until both threads have started. We do this by checking whether a
slot has been reserved by both the respective threads.
Add srv_thread_has_reserved_slot() returns slot no or ULINT_UNDEFINED.

This bug fix requires that Bug #58912 be fixed as well (bzr revision id
marko.makela@oracle.com-20101221093919-mcmmgd4zpse9567d). Otherwise,
another double BLOB free could occur when InnoDB would try to perform
an update-in-place as delete-and-insert-by-update-in-place.
row_upd_clust_rec_by_insert(): Do not disown the externally stored
columns from the old record (btr_cur_mark_extern_inherited_fields())
until after checking the foreign key constraints and successfully
inserting the updated record. If a lock wait timeout occurs between
the delete-marking of the old record and the insertion of the updated
record, mark the columns inherited before retrying the insert.
Distinguish the state UPD_NODE_INSERT_BLOB from
UPD_NODE_INSERT_CLUSTERED.
btr_cur_del_mark_set_clust_rec(): Replace the cursor with
block,rec,index,offsets so that the offsets need not be recalculated.
Assert that rec is on a clustered index leaf page.
btr_cur_disown_inherited_fields(): Renamed from
btr_cur_mark_extern_inherited_fields(). Use
upd_get_field_by_field_no(). Assert that there are externally stored
columns. Assert that a mini-transaction is passed. Remove the return
status. (The only caller, row_upd_clust_rec_by_insert(), will have
determined that some fields have changed ownership.)
btr_cur_mark_dtuple_inherited_extern(): Rename to
row_upd_clust_rec_by_insert_inherit_func() and declare as static. Add
the debug parameters rec, offsets. When rec is given, assert that the
off-page columns match those in the inesrt tuple and that the off-page
columns are owned by the record. Assert that the non-updated off-page
columns in the insert tuple are owned, and mark them inherited.
row_upd_clust_rec_by_insert_inherit(): A wrapper macro for
row_upd_clust_rec_by_insert_inherit_func().
row_undo_mod_upd_exist_sec(): Adjust a comment about
row_upd_clust_rec_by_insert().

row_upd_changes_ord_field_binary(): Do not return TRUE if the update
vector changes a column that is covered by a prefix index, but does
not change the column prefix. Add the row_ext_t parameter for
determining whether the prefixes of externally stored columns match.
dfield_datas_are_binary_equal(): Add the parameter len, for comparing
column prefixes when len > 0.
innodb.test: Add a test case where the patch of Bug #55284 failed
without this fix.
rb:537 approved by Jimmy Yang
DROP/CREATE SCHEMA, CREATE TABLE, REPAIR.
The cause of assert was concurrent execution of
DROP DATABASE and REPAIR TABLE where first statement
deleted table's file .TMD at the same time as
REPAIR TABLE tried to read file details from the old file
that was just removed.
Additionally was fixed trouble when DROP TABLE try delete
all files belong to table being dropped at the same time
when REPAIR TABLE statement has just deleted .TMD file.
No regression test added because this would require adding a
sync point to mysys/my_redel.c. Since this bug is not present in
5.5+, adding test coverage was considered unnecessary.
The patch has been verified using RQG testing.
sql/sql_db.cc:
mysql_rm_known_files() modified: ignore possible ENOENT error
when trying delete all table's files. Such aggressive
algorithm permits skip already deleted (in another thread)
files.
Installation of Drop_table_error_handler as internal error handler
moved from mysql_rm_db() to mysql_rm_knowns_files() near to place
where source of possible errors (call to mysql_rm_table_part2) located.
storage/myisam/mi_check.c:
mi_repair() was modified: set param->retry_repair= 0

The crash happens only when lower_case_table_names=2, such as on MacOS,
when running the new testcase innodb-system-table-view. Specifically,
it crashes when any query is made against the INFORMATION_SCHEMA.
INNODB_SYS_FOREIGN table. The function dict_process_sys_foreign_rec()
is only used for displaying SYS_FOREIGN records so it does not need a
lookup version of those names to be allocated. In this patch, those new
function calls are deleted.

mysys/my_symlink.c:
Fix for bug#48451: my_seek and my_tell ignore MY_WME flag
- __attribute__((unused)) removed, as myf MyFlags is
actually used in the my_realpath() function.
storage/myisam/ha_myisam.cc:
Fix for bug#48451: my_seek and my_tell ignore MY_WME flag
- check my_seek() result.
Before this fix, the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS
used uppercase to name performance schema tables.
This is inconsistent since performance schema tables have been renamed to lowercase.
Also, an old table 'PROCESSLIST' was still visible,
even after this table got renamed to 'threads'.
This fix:
- correctly uses lowercases in the output, to match the current naming.
- replaced 'PROCESSLIST' with 'threads'.
Tested the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS manually.
No automated test cases can be written for this,
since the output is too platform dependent (sizes).

To fix Bug#58226 (speed up UNIV_DEBUG), among other things we no longer
disable the inlining of the functions that are defined in InnoDB .ic files.
Inside UNIV_MEM_DEBUG, there was an implicit type conversion from void*
that is all right in C, but not in C++. Now that inlining was enabled,
the C++ compiler would see the code and complain.
Approved by Jimmy Yang on IRC.
ibuf_page(): Renamed to ibuf_page_low(). Add the parameters file, line
so that the latch diagnostics will be more meaningful.
In debug builds, add the parameter ibool x_latch. When x_latch=FALSE,
do not x-latch the page, but only buffer-fix it for reading the bit.
In UNIV_SYNC_DEBUG, display a message if an insert buffer bitmap page
was already latched. (The message should be displayed in those cases
where the code would have previously failed.)
ibuf_page(): A wrapper macro for ibuf_page_low(). Pass x_latch=TRUE.
ibuf_bitmap_page_get_bits(): Renamed to ibuf_bitmap_page_get_bits_low().
In UNIV_DEBUG, add the parameter latch_mode.
Remove the parameter mtr unless UNIV_DEBUG is defined.
ibuf_bitmap_page_get_bits(): A wrapper macro for
ibuf_bitmap_page_get_bits_low(). Pass latch_type=MTR_MEMO_PAGE_X_FIX.
buf_page_get_gen(): Use ibuf_page_low(x_latch=FALSE) in the debug assertion.
This avoids the possible deadlock.
archive_discover
Fixed buffer underrun in cleanup_dirname().
Also fixed that original (unencoded) database and table
names were used to discover archive tables.
mysql-test/r/archive.result:
A test case for BUG#58205.
mysql-test/t/archive.test:
A test case for BUG#58205.
mysys/mf_pack.c:
Fixed buffer underrun in cleanup_dirname(), when
it gets path like "a/../" (relative path, where
first directory is to be cut off).
storage/archive/ha_archive.cc:
Handler discover method gets database and table
names as is. It must use build_table_filename()
to get name similar to what it gets on create()
and open().
This is a code cleanup.
The implementation of a storage engine (subclasses of handler) is not supposed
to call my_error() directly inside the engine implementation,
but only return error codes, and report errors later at the demand
of the sql layer only (if needed), using handler::print_error().
This fix removes misplaced calls to my_error(),
and provide an implementation of print_error() instead.
Given that the sql layer implementation of create table, ha_create_table(),
does not use print_error() but returns ER_CANT_CREATE_TABLE directly,
the return code for create table statements using the performance schema
has changed to ER_CANT_CREATE_TABLE.
Adjusted the test suite accordingly.
Do not disable InnoDB inlining when UNIV_DEBUG is defined. The
inlining is now solely controlled by the preprocessor symbol
UNIV_MUST_NOT_INLINE and by any compiler options.
mtr_memo_contains(): Add an explicit type conversion from void*, so
that the function can be compiled by a C++ compiler. Previously, this
function was never seen by the C++ compiler, because it is only
present in UNIV_DEBUG builds and InnoDB inlining used to be disabled.
buf_flush_validate_skip(): A wrapper that skips most calls of
buf_flush_validate_low(). Invoked by debug assertions in
buf_flush_insert_into_flush_list() and buf_flush_remove().
fil_validate_skip(): A wrapper that skips most calls of
fil_validate(). Invoked by debug assertions in fil_io() and fil_io_wait().
os_aio_validate_skip(): A wrapper that skips most calls of
os_aio_validate(). Invoked by debug assertions in
os_aio_func(), os_aio_windows_handle() and os_aio_simulated_handle.
os_get_os_version(): Only include this function if __WIN__ is defined.
sync_array_deadlock_step(): Slight optimizations. This function is a
major CPU consumer in UNIV_SYNC_DEBUG builds.
InnoDB does not attempt to handle lower_case_table_names == 2 when looking
up foreign table names and referenced table name. It turned that server
variable into a boolean and ignored the possibility of it being '2'.
The setting lower_case_table_names == 2 means that it should be stored and
displayed in mixed case as given, but compared internally in lower case.
Normally the server deals with this since it stores table names. But
InnoDB stores referential constraints for the server, so it needs to keep
track of both lower case and given names.
This solution creates two table name pointers for each foreign and referenced
table name. One to display the name, and one to look it up. Both pointers
point to the same allocated string unless this setting is 2. So the overhead
added is not too much.
Two functions are created in dict0mem.c to populate the ..._lookup versions
of these pointers. Both dict_mem_foreign_table_name_lookup_set() and
dict_mem_referenced_table_name_lookup_set() are called 5 times each.
