Non-functional change in win-plugin/win-plugin.diff: fix the file name
before the diff, this is irrelevant but it is nice to be the same as
the file name on the following line.
* Remove a change from win-plugin/win-plugin.diff about time_t because
MySQL has used VS2005 for building 5.1.30.
* Adjust the line numbers so the patch applies cleanly without fuzz and
offset messages.

Thanks to Sunny Bains for pointing this out.
Tested as follows:
Set a breakpoint in row_merge_rename_indexes.
CREATE TABLE t(a INT)ENGINE=InnoDB;
CREATE INDEX a ON t(a);
-- The breakpoint will be reached. Kill and restart mysqld.
SHOW CREATE TABLE t;
-- This shows the MySQL .frm file, without and index.

-- This will dump the InnoDB dictionary to the error log, without the index.

from the data dictionary, because we could otherwise refuse to load old
tables (even uncompressed ones). This addresses Issue #119.
The first "row too large" check was implemented in MySQL 5.0.3
to address MySQL Bug #5682. In the InnoDB Plugin 1.0.2, a more
accurate check was implemented in innodb_strict_mode. We now
make the check unconditional.

Revert our temporary fix for "Bug#40360 Binlog related errors with binlog off"
(r2935, r2936) and deploy MySQL's one, but put the function
mysql_bin_log_is_engaged() inside mysql_addons.cc instead of in mysql's log.cc
and use a different name for it so there is no collision when MySQL adds this
function in log.cc.

1. We add a vector of locks to trx_t. This array contains the autoinc
locks granted to a transaction. There is one per table.
2. We enforce releasing of these locks in the reverse order from the
one in which they are acquired. The assumption is that since the
AUTOINC locks are statement level locks. Nested statements introduced
by triggers are stacked it should hold.
There was some cleanup done to the vector code too by adding const and
some new functions. Rename dict_table_t::auto_inc_lock to autoinc_lock.

Followup to r2935: add the Windows Delay Loader stuff for the MySQL
variable that we are accessing. If someday we have another solution for
Bug#40360 Binlog related errors with binlog off
then this should also be reverted.
Fix "Bug#40360 Binlog related errors with binlog off" in InnoDB code in order
to have a Bug#40360-free InnoDB Plugin 1.0.2.
The fix does check whether binary logging is enabled in MySQL by accessing the
opt_bin_log global variable that is defined in sql/mysqld.cc.
In case MySQL does develop another solution to this via Bug#40360 then we can
revert this patch (except the mysql-tests).
The windows-plugin part of this fix will be committed as a separate commit to
ease eventual merge into branches/5.1 [note from the future: the separate
commit went into r2936].

branches/5.1: dtype_get_sql_null_size(): return the correct storage
size of a SQL NULL column. (Bug #40369)
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
or to SQL NULL, even in ROW_FORMAT=REDUNDANT. After this fix,
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.

when INNODB_DYNAMIC_PLUGIN is specified.
The changes are:
CMakeLists.txt: add project ha_innodb for dynamic plugin on Windows.
ha_innodb depends on project mysqld.
ha_innodb.def: a new file with standard exports for a dynamic plugin.
Two new files will be added:
* sql/mysqld.def: .def file for 32-bit compiler
* sql/mysqld_x64.def: .def file for x64 compiler
It is also required to apply a patch to the MySQL source tree. The
patch is described in win-plugin/README:
win-plugin/win-plugin.diff - a patch to be applied to MySQL source
tree. When applied, the following files will be modified:
* CMakeLists.txt: add INNODB_DYNAMIC_PLUGIN and _USE_32BIT_TIME_T
* sql/CMakeLists.txt: add mysqld.def or mysqld_x64.def for mysqld
* win/configure.js: add INNODB_DYNAMIC_PLUGIN
* win/build-vs71.bat: provide an option to specify CMAKE_BUILD_TYPE
* win/build-vs8.bat: provide an option to specify CMAKE_BUILD_TYPE
* win/build-vs8_x64.bat: provide an option to specify CMAKE_BUILD_TYPE
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
system variables.
handler/handler0alter.cc: add a header file
handler/i_s.cc: add a header file
