and clarifies the invariant in dict_table_get_on_id().
In Mar 2007 Marko observed a crash during recovery, the crash resulted from
an UNDO operation on a system table. His solution was to acquire an X lock on
the data dictionary, this in hindsight was an overkill. It is unclear what
caused the crash, current hypothesis is that it was a memory corruption.
The X lock results in performance issues by when undoing changes due to
rollback during normal operation on regular tables.
Why the change is safe:
======================
The InnoDB code has changed since the original X lock change was made. In the
new code we always lock the data dictionary in X mode during startup when
UNDOing operations on the system tables (this is a given). This ensures that
the crash Marko observed cannot happen as long as all transactions that update
the system tables follow the standard rules by setting the appropriate DICT_OP
flag when writing the log records when they make the changes.
If transactions violate the above mentioned rule then during recovery (at
startup) the rollback code (see trx0roll.c) will not acquire the X lock
and we will see the crash again. This will however be a different bug.
In semi-consistent read, only unlock freshly locked non-matching records.
Define DB_SUCCESS_LOCKED_REC for indicating a successful operation
where a record lock was created.
lock_rec_lock_fast(): Return LOCK_REC_SUCCESS,
LOCK_REC_SUCCESS_CREATED, or LOCK_REC_FAIL instead of TRUE/FALSE.
lock_sec_rec_read_check_and_lock(),
lock_clust_rec_read_check_and_lock(), lock_rec_enqueue_waiting(),
lock_rec_lock_slow(), lock_rec_lock(), row_ins_set_shared_rec_lock(),
row_ins_set_exclusive_rec_lock(), sel_set_rec_lock(),
row_sel_get_clust_rec_for_mysql(): Return DB_SUCCESS_LOCKED_REC if a
new record lock was created. Adjust callers.
row_unlock_for_mysql(): Correct the function documentation.
row_prebuilt_t::new_rec_locks: Correct the documentation.

message:
Followup to Bug#51920, fix binlog.binlog_killed
This is a followup to the fix of
Bug#51920 Innodb connections in row lock wait ignore KILL until lock wait
timeout
in that fix (rb://279) the behavior was changed to honor when a trx is
interrupted during lock wait, but the returned error code was still
"lock wait timeout" when it should be "interrupted".
This change fixes the non-deterministically failing test binlog.binlog_killed,
that failed like this:
binlog.binlog_killed 'stmt' [ fail ]
Test ended at 2010-05-12 11:39:08

InnoDB logs error repeatedly when trying to load page into buffer pool
In buf_page_get_gen() if we are unable to read a page (because of

error log with millions of entries in no time and we'd eventually run
out of disk space. This patch limits the number of attempts that we
make (currently set to 100) and after that we abort with a message.

branches/5.1: Merge r4922 from branches/zip.
This the fix for the first part of Bug #41609 from InnoDB Plugin to
the built-in InnoDB in MySQL 5.1. This allows InnoDB Hot Backup to
back up a database while the built-in InnoDB in MySQL 5.1 is creating
temporary tables. (This fix does not address the printouts about
missing .ibd files for temporary tables at InnoDB startup, which was
committed to branches/zip in r6252.)
rb://219 approved by Sunny Bains.
branches/zip: Distinguish temporary tables in MLOG_FILE_CREATE.
This addresses Mantis Issue #23 in InnoDB Hot Backup and some
of MySQL Bug #41609.
In MLOG_FILE_CREATE, we need to distinguish temporary tables, so that
InnoDB Hot Backup can work correctly. It turns out that we can do this
easily, by using a bit of the previously unused parameter for page number.
(The page number parameter of MLOG_FILE_CREATE has been written as 0
ever since MySQL 4.1, which introduced MLOG_FILE_CREATE.)
MLOG_FILE_FLAG_TEMP: A flag for indicating a temporary table in
the page number parameter of MLOG_FILE_ operations.
fil_op_write_log(): Add the parameter log_flags.
fil_op_log_parse_or_replay(): Add the parameter log_flags.
Do not replay MLOG_FILE_CREATE when MLOG_FILE_FLAG_TEMP is set in log_flags.
This only affects ibbackup --apply-log. InnoDB itself never replays file
operations.

branches/5.1: fix bug#3139: Mysql crashes: 'windows error 995'
after several selects on a large DB
During stress environment, Windows AIO may fail with error code
ERROR_OPERATION_ABORTED. InnoDB does not handle the error, rather
crashes. The cause of the error is unknown, but likely due to
faulty hardware or driver.
This patch introduces a new error code OS_FILE_OPERATION_ABORTED,
which maps to Windows ERROR_OPERATION_ABORTED (995). When the error
is detected during AIO, the InnoDB will issue a synchronous retry
(read/write).
This patch has been extensively tested by MySQL support.

When MySQL Bug #20877 was fixed in r834, this function was
accidentally modified to return 0 or 1. Apparently, the only impact of
this bug is that fixed-length columns cannot be updated in-place from

fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
storage size as they should, no matter if NULL or non-NULL. The bug
caused fixed-length NULL columns to occupy 1 byte.

branches/5.1: This bug has always existed but was masked by other errors. The
fix for bug# 38839 triggered this bug. When the offset and increment are > 1
we need to calculate the next value taking into consideration the two
variables. Previously we simply assumed they were 1 particularly offset was
never used. MySQL does its own calculation and that's probably why it seemed
to work in the past. We would return what we thought was the correct next
value and then MySQL would recalculate the actual value from that and return
it to the caller (e.g., handler::write_row()). Several new tests have been
added that try and catch some edge cases. The tests exposed a wrap around
error in MySQL next value calculation which was filed as bug 39828. The tests
will need to be updated once MySQL fix that bug.
One good side effect of this fix is that dict_table_t size has been
reduced by 8 bytes because we have moved the autoinc_increment field to
the row_prebuilt_t structure. See review-board for a detailed discussion.

branches/5.1 issue# 4
Fixed a timing hole where a thread dropping an index can free the
in-memory index struct while another thread is still using
that structure to remove entries from adaptive hash index belonging
to one of the pages that belongs to the index being dropped.
The fix is to have a reference counter in the index struct and to
wait for this counter to drop to zero beforing freeing the struct.

the size of the UNDO slots cache lists (insert and upate). If either of
cached lists has more than 500 entries then we add any UNDO slots that are
freed, to the common free list instead of the cache list, this is to avoid
the case where all the free slots end up in only one of the lists on startup
after a crash.

Fixed bug#30059.
Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.

This is a combination of changes that forward port the scalability fix applied to 5.0
through r1001.
It reverts changes r149 and r122 (these were 5.1 specific changes made in lieu of
scalability fix of 5.0)
Then it applies r1001 to 5.0 which is the original scalability fix.
Finally it applies r2082 which fixes an issue with the original fix.

We don't rely on *first_value to be 0 when checking whether

ChangeSet@1.2536.50.1 2007-08-02 12:45:56-07:00 igor@mysql.com
Fixed bug#28404.
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT.
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.

bug #28404.

Enclose rw_lock_validate() in #ifdef UNIV_DEBUG. It is only called by
debug assertions.

Revision r1850:
Implement this feature request:
http://bugs.mysql.com/30706
* Add a function that returns the number of microseconds since
epoch - ut_time_us().
* Add (innodb|innobase|srv)_replication_delay MySQL config parameter.
* Add UT_WAIT_FOR() macro that waits for a specified condition to occur
until a timeout elapses.
* Using all of the above, handle the replication thread specially in
srv_conc_enter_innodb().

Revision r1873:
snprintf() should always return non-negative result. According to
Microsoft documentation about _vscprintf():
If format is a null pointer, the invalid parameter handler is invoked,
as described in Parameter Validation. If execution is allowed to
continue, the functions return -1 and set errno to EINVAL.
The UNIX variant of snprintf() segfaults if format is a NULL pointer
(similar to strlen(NULL) for example), so it is better to conform to
this behavior and crash our custom Windows version instead of
returning -1. Noone would expect -1 to be returned from snprintf().
Cosmetic: Add a space after typecast.
Approved by: Marko
Revision r1862:
Add ut_snprintf() function. On Windows this needs to be implemented
using auxiliary functions because there is no snprintf-variant on
Windows that behaves exactly as specified in the standard:
* Always return the number of characters that would have been printed
if the size were unlimited (not including the final `\0').
* Always '\0'-terminate the result
* Do not touch the buffer if size=0, only return the number of characters
that would have been printed. Can be used to estimate the size needed
and to allocate it dynamically.
See http://www.freebsd.org/cgi/query-pr.cgi?pr=87260 for the reason why
2 ap variables are used.

Revision r1787:
Move the prototype of innobase_print_identifier() from ut0ut.c to
ha_prototypes.h. Enclose the definitions in ha_prototypes.h in
#ifndef UNIV_HOTBACKUP.
Revision r1789:
ut_print_namel(): Do not assume that all '/' are separators between
database and table names.
Approved by Heikki.
Revision r1936:
ut_print_buf(): Add a Valgrind check that the buffer is wholly defined.
