If the expression for a virtual column of table contained datetime
comparison then the execution of the second query that used this
virtual column caused a crash. It happened because the execution
of the first query that used this virtual column inserted a cached
item into the expression tree. The cached tree was allocated in
the statement memory while the expression tree was allocated in
the table memory.
Now the cached items that are inserted into expressions for virtual
columns with datetime comparisons are always allocated in the same
mem_root as the expressions for virtual columns. So now the inserted
cached items are valid for any queries that use these virtual columns.
The issue was that we didn't always check result of ha_rnd_init() which caused a problem for handlers that returned an error in this code.
- Changed prototype of ha_rnd_init() to ensure that we get a compile warning if result is not checked.
- Added ha_rnd_init_with_error() that prints error on failure.
- Checked all usage of ha_rnd_init() and ensure we generate an error message on failures.
- Changed init_read_record() to return 1 on failure.

The problem was duplicated memory usage with long packed keys.
There were two problems that caused wrong results reported with this bug.
1. In some cases stored(persistent) virtual columns were not marked
in the write_set and in the vcol_set bitmaps.
2. If the list of fields in an insert command was empty then the values of
the stored virtual columns were set to default.
To fix the first problem the function st_table::mark_virtual_columns_for_write
was modified. Now the function has a parameter that says whether the virtual
columns are to be marked for insert or for update.
To fix the second problem a special handling of empty insert lists is
added in the function fill_record().
If a virtual column was used in the ORDER BY clause of a query
and some of the columns this virtual column was based upon were
not referenced anywhere in the query then the execution of the
query could cause an assertion failure.
It happened because in this case the bitmap of the columns used
for ordering keys was not formed correctly.
There was no error thrown when creating a table with a virtual table
computed by an expression returning a row.
This caused a crash when inserting into the table.
Removed periods at the end of the error messages for virtual columns.
Adjusted output in test result files accordingly.
The functions mysql_delete and mysql_update lacked calls of
updated_virtual_fields(). This caused wrong results for
some DELETEs/UPDATEs.
Added test cases for this bug.
Most of the changes are backports from MySQL 5.5. Please note
that the 64-bit build fails with VS 2010 and the 32-bit build
has problems running mysql-test-run.pl.
* Added files for compiling with VS 2010 and added them
to Makefile.am.
* ifdef'ed ETIMEDOUT, because it is defined by VS 2010 now
* Removed not needed /MAP's from cmake files
- Fixed memory leaks in mysqldump
- Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
- Fixed realloc() problem that caused out of memory when running mysqldump.test on OpenSolaris
client/mysqldump.c:
Fixed memory leaks
Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
client/mysqltest.cc:
Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
include/my_global.h:
Added simple macro val_or_null() to simplify detecting of NULL strings for printf
sql/handler.cc:
Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
sql/sql_db.cc:
Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
Removed testing of 'new_db_name' as this is guranteed never NULL
sql/sql_show.cc:
Fixed printf of NULL which caused crashes on OpenSolaris when using --debug
storage/csv/ha_tina.cc:
Fixed realloc() problem that caused out of memory when running mysqldump.test on OpenSolaris
(OpenSolaris default malloc() can't handle a lot of reallocs() of strings that are growing one byte at a time)
This did speed up logging to cvs with a magnitude for large strings.
storage/maria/unittest/ma_pagecache_single.c:
Check if we can flush write locked page for normal flush
Check that we can't flush read locked page with FLUSH_KEEP_LAZY (used by checkpoint)
- Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
- Fixed a rase condition when two threads calls external_lock and thr_lock() in different order. When this happend the transaction that called external lock first
and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
- Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id
- Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
- Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
client/mysqldump.c:
Add "" around error message to make it more readable
client/mysqltest.cc:
Free environment variables
mysql-test/r/mysqldump.result:
Updated results
mysql-test/r/openssl_1.result:
Updated results
mysql-test/suite/maria/r/maria-recover.result:
Updated results
mysql-test/suite/maria/r/maria3.result:
Updated results
mysql-test/suite/maria/t/maria3.test:
Added more test of temporary tables
storage/maria/ha_maria.cc:
Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
Start transaction in ma_block_get_status() instead of in ha_maria::external_lock().
- This fixes a rase condition when two threads calls external lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
Store latest transaction id in controll file if recovery was done.
- This allows one to run maria_chk on an automatcally recovered tables without warnings about too small transaction id
storage/maria/ha_maria.h:
Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
storage/maria/ma_blockrec.h:
Added new function "_ma_block_get_status_no_versioning()"
storage/maria/ma_init.c:
Added hook to create trn in ma_block_get_status() if we are using MariaDB
storage/maria/ma_open.c:
Ensure we call _ma_block_get_status_no_versioning() for transactional tables without versioning (like tables with fulltext)
storage/maria/ma_pagecache.c:
Allow one to flush blocks that are pinned for read.
This fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
storage/maria/ma_recovery.c:
Set maria_recovery_changed_data to 1 if recover changed something.
Set max_trid_in_control_file to max found trn if we found a bigger trn.
The allows will ensure that the control file is up to date after recovery which allows one to run maria_chk on the tables without warnings about too big trn
storage/maria/ma_state.c:
Call maria_create_trn_hook() in _ma_setup_live_state() instead of ha_maria::external_lock()
This ensures that 'state' and trn are in sync and thus fixes the race condition mentioned for ha_maria.cc
storage/maria/ma_static.c:
Added maria_create_trn_hook() and maria_recovery_changed_data
storage/maria/maria_def.h:
Added MARIA_HANDLER->external_ptr, which is used to hold MariaDB thd.
Added some new external variables
Removed reference to non existing function: maria_concurrent_inserts()
