- 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.
view definition
During SHOW CREATE VIEW there is no reason to 'anonymize'
errors that name objects that a user does not have access
to. Moreover it was inconsistently implemented. For example
base tables being referenced from a view appear to be ok,
but not views. The manual on the other hand is clear: If a
user has the privileges SELECT and SHOW VIEW, the view
definition is available to that user, period. The fix
changes the behavior to support the manual.

SHOW CREATE VIEW from this check.

Bug#35996: The fix: An Internal_error_handler that hides

no Internal_error_handler.
* 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.
Details:
1. Add missing "disconnect <session>"
2. Take care that the disconnects are finished when the test terminates
3. Replace error names by error numbers
4. Minor beautifying of script code
Fix mysql-test-run.pl to not terminate early when warnings in error logs are detected during
server shutdown. Instead, give a nice summary report at the end of the failures.
Fix code to make 100% sure no failures will go undetected.
Revert earlier wrong change.
Fix race with port allocation semaphore file permissions.
Adjust testsuite to copy with new PBXT engine now in the tree. The PBXT engine causes an
extra table to appear in the INFORMATION_SCHEMA. This causes different output for a few
test cases.
dbug/dbug.c:
If DbugParse() is called multiple times, the stack->keywords for the
top stack frame could be overwritten without being freed, causing a
memory leak reported by Valgrind.

mysql-test/lib/mtr_report.pm:
Give a nice summary report at the end of tests of any warnings seen in logs during
server shutdowns.
mysql-test/lib/mtr_unique.pm:
Move chmod 777 to greatly reduce the risk of leaving the port semaphore file unaccessible
bu other users.
mysql-test/mysql-test-run.pl:
Don't abort in case of warnings detected, instead give a nice summary report.
Fix code to make 100% sure no failures will go undetected.
Revert earlier wrong change when master disconnects early.

Document potential problem with String::c_ptr() and String() constructor with caller-supplied buffer.
storage/archive/azio.c:
Silence Valgrind false warning for libz.
The problem:
I_S views table does not check the presence of SHOW_VIEW_ACL|SELECT_ACL
privileges for a view. It leads to discrepancy between SHOW CREATE VIEW
and I_S.VIEWS.
The fix:
added appropriate check.

The fix is: if user has privileges to view fields and user has any
(insert,select,delete,update) privileges on underlying view
then 'show fields' and select from I_S.COLUMNS table are sucsessful.

Bug#18282 "INFORMATION_SCHEMA.TABLES provides inconsistent info about invalid views"
This bug caused crashes or resulted in wrong data being returned
when one tried to obtain information from I_S tables about views
using stored functions.
It was caused by the fact that we were using LEX representing
statement which were doing select from I_S tables as active LEX
when contents of I_S table were built. So state of this LEX both
affected and was affected by open_tables() calls which happened
during this process. This resulted in wrong behavior and in
violations of some of invariants which caused crashes.
This fix tries to solve this problem by properly saving/resetting
and restoring part of LEX which affects and is affected by the
process of opening tables and views in get_all_tables() routine.
To simplify things we separated this part of LEX in a new class
and made LEX its descendant.

sql/sql_lex.cc:
To simplify saving/resetting and restoring part of LEX which
affects and is affected by the process of opening tables and
views we moved it to new class Query_tables_list and made LEX
descendant of this class. Also introduced two LEX methods
which can be used to save and reset or to restore this state.
sql/sql_lex.h:
To simplify saving/resetting and restoring part of LEX which
affects and is affected by the process of opening tables and
views we moved it to new class Query_tables_list and made LEX
descendant of this class. Also introduced two LEX methods
which can be used to save and reset or to restore this state.
sql/sql_show.cc:
Now in get_all_tables() routine we properly save/reset and
restore part of LEX (statement table list and information
about routines used) which affects and is affected by the
process of opening tables and views.
sql/sql_table.cc:
Now we clean-up LEX after opening table (view) in two stages.
In the first stage we call LEX::cleanup_after_one_table_open()
to clean-up selects lists and derived tables state. In the
second stage which happens after close_thread_tables() is
invoked we call Query_tables_list::reset_query_tables_list(FALSE)
to rollback changes in Query_tables_list.
Crash happened when one selected data from one of INFORMATION_SCHEMA
tables and in order to build its contents server had to open view which
used stored function and table or view on which one had not global or
database-level privileges (e.g. had only table-level or had no
privileges at all).
The crash was caused by usage of check_grant() function, which assumes
that either number of tables to be inspected by it is limited explicitly
or table list used and thd->lex->query_tables_own_last value correspond
to each other (the latter should be either 0 or point to next_global
member of one of elements of this table list), in conditions when
above assumptions were not true. This fix just explicitly limits
number of tables to be inspected. Other negative effects which are
caused by the fact that thd->lex->query_tables_own_last might not
be set properly during processing of I_S tables are less disastrous
and will be reported and fixed separetely.
