on Windows, which includes:
* Load mysqld.map and insert all symbol/address pairs into hash for
quick access
* Resolves all external data variables. The delayloading mechanism
in MSVC does not support automatic imports of data variables.
A workaround is to explicitly handle the data import using the delay
loader during the initialization of the plugin.
* Resolves all external functions during run-time, by implementing
the delayed loading helper function delayLoadHelper2, which is
called by run-time as well as HrLoadAllImportsForDll.
The delay loader reuses the hash implementation in InnoDB. The normal
hash_create (in hash0hash.c) creates hash tables in buffer pool. But
the delay loader is invoked before the engine is initialized, and
buffer pools are not ready yet. Instead, the delay loader has its own
implementation of hash_create() and hash_table_free(), called
wdl_hash_create() and wdl_hash_table_free().
This patch should be used with other two patches in order to build
a dynamically linked plugin on Windows:
* patch for tmpfile functions (r2886)
* patch for "build" files (to be committed)
The list of file changed:
handler/handler0vars.h: new file, defines a list of external data
variables (no external functions).
handler/win_delay_loader.cc: new file, the implementation of the delay
loader for Windows plugin.
handler/ha_innodb.cc: add a header file, and changes for copying the

In ha_innobase::info() - do not try to get the free space for a tablespace
which has been discarded with ALTER TABLE ... DISCARD TABLESPACE or if the
.ibd file is missing for some other reason.
ibd_file_missing and tablespace_discarded are manipulated only in
row_discard_tablespace_for_mysql() and in row_import_tablespace_for_mysql()
and the manipulation is protected/surrounded by
row_mysql_lock_data_dictionary()/row_mysql_unlock_data_dictionary() thus we
do the same in ha_innobase::info() when checking the values of those members
to avoid race conditions. I have tested the code-path with UNIV_DEBUG and
UNIV_SYNC_DEBUG.
Looks like it is not possible to avoid mysqld printing warnings in the

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.

message:
Bug#20129: ALTER TABLE ... REPAIR PARTITION ... complains that
partition is corrupt
The main problem was that ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR
PARTITION took another code path (over mysql_alter_table instead of
mysql_admin_table) which differs in two ways:
1) alter table opens the tables in a different way than admin tables do
resulting in returning with error before it tried the command
2) alter table does not start to send any diagnostic rows to the client
which the lower admin functions continue to use -> resulting in
assertion crash
The fix:
Remapped ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR PARTITION to use
the same code path as ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE t.
Adding check in mysql_admin_table to setup the partition list for
which partitions that should be used.
Partitioned tables will still not work with
REPAIR TABLE/PARTITION USE_FRM, since that requires moving partitions
to tables, REPAIR TABLE t USE_FRM, and check that the data still
fulfills the partitioning function and then move the table back to
being a partition.
NOTE: I have removed the following functions from the handler
interface:
analyze_partitions, check_partitions, optimize_partitions,
repair_partitions
Since they are not longer needed.
THIS ALTERS THE STORAGE ENGINE API
I have verified that OPTIMIZE TABLE actually rebuilds the table
and calls ANALYZE.

------------------------------------------------------------------------
The cardinality of every index (the number of different key values) is
calculated when the table is opened, at SHOW TABLE STATUS,
ANALYZE TABLE and on other circumstances (like when the table has
changed too much). Note that if the mysql client is running with the
auto-rehash setting turned on (default) this causes all tables to be
opened when it starts.
Previously InnoDB sampled 8 random pages from the index to get an
estimate of the cardinality. Now the number of sampled pages can be
changed via the global parameter innodb_stats_sample_pages which can
be tuned at runtime. The default value for this parameter is 8.
If the value of this parameter is changed, there may be serious problems:
- small values (say, 1) can cause an error in table stats;
- values much larger than 8 (say, 100), can cause a big slowdown in
table opening time, SHOW TABLE status, etc.
- query plans may be different from the old ones.

message:
Bug#31210: INSERT DELAYED crashes server when used on partitioned tables
Problem was an unclear error message since it could suggest that
MyISAM did not support INSERT DELAYED.
Changed the error message to say that DELAYED is not supported by the
table, instead of the table's storage engine.
The confusion is that a partitioned table is in somewhat sense using
the partitioning storage engine, which in turn uses the ordinary
storage engine. By saying that the table does not support DELAYED we
do not give any extra informantion about the storage engine or if it
is partitioned.

Rewrite the function innodb_plugin_init() to support parameters in
different order (in static and dynamic InnoDB) and to support more
parameters in the static InnoDB.
The previous implementation traversed both lists at the same time,
skipping parameters in the dynamic list that do not exist in the static
list. E.g. both lists were allowed to be static=(a, b, c),
dynamic=(a, b, c) or static=(a, b, c), dynamic=(a, b, x, c).
With the new implementation they are allowed to be
static=(a, b, c), dynamic=(b, a, c) or
static=(a, b, x, c), dynamic=(b, a, c) in addition.
The new implementation has complexity O(N^2) while the old one was O(N),
but this is acceptable sacrifice provided that innodb_plugin_init() is
called once per InnoDB lifetime and that N=39 currently, and N is not
going to increase much in the future, N=number of the InnoDB parameters.

from os_file_handle_error(). Also, checks for full path pattern during

Implement the system tablespace tagging described on the wiki:
https://svn.innodb.com/innobase/InnoDB_version_and_feature_compatibility
A brief description of the changes:
* The file format tag will be saved in the trx system page, starting at
(UNIV_PAGE_SIZE - 16) for 8 bytes.
* The configuration parameter innodb_file_format_check is introduced.
This variable can be set to on/off and any of the supported file
formats in the configuration file, but can only be set to any of
the supported file formats during runtime. The default is on.
* During table create/open, check the current file format against
the max in file_format_max. If the current file format is newer,
update file_format_max and tag the system tablespace with the
newer one in a normal mtr.
* During startup, write the tag to the error log and check it against
DICT_TF_FORMAT_MAX. Refuse to start with error, if
-- DICT_TF_FORMAT_MAX < the tag, and
-- innodb_file_format_check is ON
Print out a warning , if
-- DICT_TF_FORMAT_MAX < the tag, but
-- innodb_file_format_check is off
* The system tablespace tag is re-settable using:
set innodb_file_format_check = <file_format>
Approved by: Sunny
Add InnoDB version in these places:
* In INFORMATION_SCHEMA.PLUGINS.PLUGIN_VERSION, only 1.2 out of 1.2.3
because MySQL supports only one dot there
* At startup:
"080501 12:28:06 InnoDB Plugin 1.0.1 started; log sequence number 46509"
* In a server variable innodb_version;
mysql> select @@innodb_version;

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.

described in Mantis#30. Specifically:
- Allow innodb_file_format to take string arguments
- Make innodb_file_format system variable a string instead of a number
- Implement the callback functions
- Update warning messages
Three new functions are implemented:
file_format_name_lookup(): Validate the file format name and return
its corresponding id.
innodb_file_format_check(): Check if it is a valid file format. This
function is registered as a callback with MySQL.
innodb_file_format_update(): Update the global variable using the
"saved" value. This functions is registered as a callback with MySQL.
Introduced a new session level config param innodb_strict_mode.
If it is set we do extra checking at time of table creation
and fail if any invalid combination of KEY_BLOCK_SIZE
or ROW_FORMAT is specified.
