- Marked a couple of tests with --big
- Fixed xtradb/handler/ha_innodb.cc to call explain_filename()
storage/xtradb/handler/ha_innodb.cc:
Call explain_filename() to get proper names for partitioned tables
- Make index condition pushdown be controlled by an @@optimizer_switch flag,
not by @@engine_condition_pushdown
- Make MRR buffer size be controlled by @@mrr_buffer_size, not
by @@read_rnd_buffer_size
- Move parts of code to separate files
- Code cleanup
- Add --sorted_result to some SELECTs in tests.
The problem is a somewhat common misusage of the strmake function.
The strmake(dst, src, len) function writes at most /len/ bytes to
the string pointed to by src, not including the trailing null byte.
Hence, if /len/ is the exact length of the destination buffer, a
one byte buffer overflow can occur if the length of the source
string is equal to or greater than /len/.
client/mysqldump.c:
Make room for the trailing null byte.
libmysql/libmysql.c:
Add comment, there is enough room in the buffer.
Increase buffer length, two strings are concatenated.
libmysqld/lib_sql.cc:
Make room for the trailing null byte.
mysys/default.c:
Make room for the trailing null bytes.
mysys/mf_pack.c:
Make room for the trailing null byte.
server-tools/instance-manager/commands.cc:
Copy only if overflow isn't possible in both cases.
server-tools/instance-manager/listener.cc:
Make room for the trailing null byte.
sql/log.cc:
Make room for the trailing null byte.
sql/sp_pcontext.h:
Cosmetic fix.
sql/sql_acl.cc:
MAX_HOSTNAME already specifies space for the trailing null byte.
sql/sql_parse.cc:
Make room for the trailing null byte.
sql/sql_table.cc:
Make room for the trailing null byte.
WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface"
WL#2475 "Batched range read functions for MyISAM/InnoDb"
"Index condition pushdown for MyISAM/InnoDB"
Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614:
There could be observed the following problems:
1. EXPLAIN did not mention pushdown conditions from on expressions in the
'extra' column. As a result if a query had no where conditions pushed
down to a table, but had on conditions pushed to this table the 'extra'
column in the EXPLAIN for the table missed 'using where'.
2. Conditions for ref access were not eliminated from on expressions
though such conditions were eliminated from the where condition.
- 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.
- Read plug.in to fid the name of the engine to link with, does not have
to be same as engine dir
- Use engine dir when figuring out which libraries to build limbysqld with
"Merge Monty's fixes from main into release branch" .. cset):
- mysql_get_server_name() is a new client API function and so should
be exported from libmysql[d].

mysql_get_server_name() is a new client API function and so should

Backport from 6.0 to 5.1.
Only those sync points are included, which are used in debug_sync.test.
The Debug Sync Facility allows to place synchronization points
in the code:
open_tables(...)
DEBUG_SYNC(thd, "after_open_tables");
lock_tables(...)
When activated, a sync point can
- Send a signal and/or
- Wait for a signal
Nomenclature:
- signal: A value of a global variable that persists
until overwritten by a new signal. The global
variable can also be seen as a "signal post"
or "flag mast". Then the signal is what is
attached to the "signal post" or "flag mast".
- send a signal: Assign the value (the signal) to the global
variable ("set a flag") and broadcast a
global condition to wake those waiting for
a signal.
- wait for a signal: Loop over waiting for the global condition until
the global value matches the wait-for signal.
Please find more information in the top comment in debug_sync.cc
or in the worklog entry.

Restore a stub of the removed mysql_odbc_escape_string function
to fix a ABI breakage. The function was intended to be private
and used only by Connector/ODBC, but, unfortunately, it was exported
as part of the ABI. Nonetheless, only a stub is restored as the
original function is inherently broken and shouldn't be used.
This restoration only applies to MySQL 5.0. This will be addressed
differently in later versions -- reworked library versioning.

* Finished Monty and Jani's merge

xtradb.
- Define and pass compile time path variables as pre-processor definitions to
mimic the makefile build.
- Set new CMake version and policy requirements explicitly.
- Changed DATADIR to MYSQL_DATADIR to avoid conflicting definition in
Platform SDK header ObjIdl.h which also defines DATADIR.
an assertion in a debug build.
The reason is that the C API doesn't support multiple result sets for prepared
statements and attempting to execute a stored routine which returns multiple result
sets sometimes lead to a network error. The network error sets the diagnostic area
prematurely which later leads to the assert when an attempt is made to set a second
server state.
This patch fixes the issue by changing the scope of the error code returned by
sp_instr_stmt::execute() to include any error which happened during the execution.
To assure that Diagnostic_area::is_sent really mean that the message was sent all
network related functions are checked for return status.

This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client

The reason for the error is incorrectly specified link dependencies
for mysql_embedded, mysqltest_embedded and mysql_client_test_embedded
in CMakeLists.txt (ADD_DEPENDENCIES should be TARGET_LINK_LIBRARIES)
libmysqld/CMakeLists.txt:
changed library type for libmysqld to SHARED instead of
MODULE. MODULE in CMake notation is a shared library that
is used only in dlopen/dlsym/LoadLibrary scenarios.
Hence it was impossible to use TARGET_LINK_LIBRARIES with
a MODULE.
libmysqld/examples/CMakeLists.txt:
Use TARGET_LINK_LIBRARIES (instead of previously incorrectly
used ADD_DEPENDENCIES) to specify link dependency from libmysqld

--extra-port=# ; Extra tcp port that uses the old one-thread-per-connection method
