  branches/zip: page_cur_insert_rec_zip(): When allocating insert_buf
  from the free list, zero out the DB_TRX_ID and DB_ROLL_PTR of the
  deleted record if the new record would not overwrite these
  fields. This fixes a harmless content mismatch reported by
  page_zip_validate() that was reported as Issue #111.

  Revert our temporary fix for Bug#40360 Binlog related errors with binlog off

  This bug was fixed in MySQL code.

  Our fix went into r2944 and r2947, but this patch does not entirely revert
  those revisions because we want to leave the test case that was introduced
  and also r2944 itself reverted r2935 and r2936. So if we completely revert
  r2944 and r2947 then we would loose the test and will restore r2935 and
  r2936.

  This resolves Issue#108 We should remove ib_bin_log_is_engaged() once mysql
  add an equivallent, see Bug#40360

    branches/5.1 bug#40760

    The config param innodb_thread_concurrency is dynamically set and is
    read when a thread enters/exits innodb. If the value is changed between
    the enter and exit time the behaviour becomes erratic.
    The fix is not to use srv_thread_concurrency when exiting, instead use
    the flag trx->declared_to_be_inside_innodb.

      message:
        A fix for Bug#22891 "session level max_allowed_packet can be
        set but is ignored".

        This patch makes @@session.max_allowed_packed and
        @@session.net_buffer_length read-only as suggested in the bug
        report. The user will have to use SET GLOBAL (and reconnect)
        to alter the session values of these variables.

        The error string ER_VARIABLE_IS_READONLY is introduced.

        Tests are modified accordingly.

  branches/zip: row_merge_drop_temp_indexes(): Replace the WHILE 1 with
  WHILE 1=1 in the SQL procedure, so that the loop will actually be
  entered and temporary indexes be dropped during crash recovery.
  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.
  CREATE TABLE innodb_table_monitor(a INT)ENGINE=InnoDB;
  -- This will dump the InnoDB dictionary to the error log, without the index.

  branches/zip: Always check for "row too large" when executing SQL to create
  an index or table.  We have to skip this check when loading table definitions
  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.

  dict_create_index_step(): Pass strict=TRUE to dict_index_add_to_cache().

  trx_is_strict(), thd_is_strict(): Remove.

  innodb-zip.test: Test in innodb_strict_mode=OFF.

  branches/zip: implement the delayloading of externals for the plugin
  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

    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.

  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

  "flags" with "format_id", because this function should deal with file
  format identifiers, not with table flags.

  trx_sys_file_format_max_write(), trx_sys_file_format_max_set(): Add a
  const qualifier to the parameter "name".

  ha_innodb.cc: Correct the spelling in some comments: "side effect".
  Remove redundant prototypes for some static callback functions.

  innodb_file_format_name_update(), innodb_file_format_check_update():
  Correct the function signature.  Use appropriate pointer type conversions.

  MYSQL_SYSVAR_STR(file_format), MYSQL_SYSVAR_STR(file_format_check):
  Remove the type conversions from the callback function pointers.  When
  the function signatures match, no type conversion is needed.  The type
  conversions would only prevent compilation warnings for any mismatch.

Fix Bug#25640:

Introduce an user visible parameter innodb_stats_sample (default 8,
min 1, max 1000) and use that parameter instead of the
BTR_KEY_VAL_ESTIMATE_N_PAGES macro. Remove this macro.

468d425d53 branches/zip: Hide some global variables that were accidentally not hidden
in r2276.  Now the following symbols will be exported when InnoDB is built
as a dynamic plugin:

* the virtual method pointer table of class ha_innodb
* the three variables that MySQL will reference when linking at runtime:

	_mysql_plugin_declarations_
	_mysql_plugin_interface_version_
	_mysql_sizeof_struct_st_plugin_

Furthermore, the following symbols are weak globals, to allow us to access
the built-in InnoDB in the mysqld executable, in case it contains a statically
linked InnoDB:

	builtin_innobase_plugin
	innodb_hton_ptr

1d1dc31a06 branches/zip: Introduce UNIV_INTERN, a linkage specifier for InnoDB-global
symbols.  Use it for all definitions of non-static variables and functions.

lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static.  It is
referenced from pars0grm.c.

Actually, according to
	nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:

* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs

The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.

The class ha_innodb is renamed from class ha_innobase by a #define.  Thus,
there will be no clash with the builtin InnoDB.  However, there will be some
overhead for invoking virtual methods of class ha_innodb.  Ideas for making
the vtable hidden are welcome.  -fvisibility=hidden is not available in GCC 3.

Change the format of TRX_IDs in INFORMATION_SCHEMA tables from DEC to
HEX.

The current TRX_IDs are hard to remember and track down: 426355, 428466,
428566, etc.

In HEX:
* there are less "digits", the strings are shorter;
* since there are 16 instead of 10 "digits", the chance of having
  repeating ones are smaller.

The above look like 68173, 689B2, 68A16 in HEX.

acf84dfb75 branches/zip: Fast index creation: Lock the data dictionary only after
acquiring the table lock.  The data dictionary should not be locked for
long periods.  Before this change, in the worst case, the dictionary
would be locked until the expiration of innodb_lock_wait_timeout.

Virtually, transaction-level locks (locks on database objects, such
as records and tables) have a latching order level of SYNC_USER_TRX_LOCK,
which is above any InnoDB rw-locks or mutexes.  However, the latching
order of SYNC_USER_TRX_LOCK is never checked, not even by UNIV_SYNC_DEBUG.

71a4f691b2 branches/zip: Fast index creation: Remove the ROW_PREBUILT_OBSOLETE nonsense.
Active transactions must not switch table or index definitions on the fly,
for several reasons, including the following:

 * copied indexes do not carry any history or locking information;
   that is, rollbacks, read views, and record locking would be broken

 * huge potential for race conditions, inconsistent reads and writes,
   loss of data, and corruption

Instead of trying to track down if the table was changed during a transaction,
acquire appropriate locks that protect the creation and dropping of indexes.

innodb-index.test: Test the locking of CREATE INDEX and DROP INDEX.  Test
that consistent reads work across dropped indexes.

lock_rec_insert_check_and_lock(): Relax the lock_table_has() assertion.
When inserting a record into an index, the table must be at least IX-locked.
However, when an index is being created, an IS-lock on the table is
sufficient.

row_merge_lock_table(): Add the parameter enum lock_mode mode, which must
be LOCK_X or LOCK_S.

row_merge_drop_table(): Assert that n_mysql_handles_opened == 0.
Unconditionally drop the table.

ha_innobase::add_index(): Acquire an X or S lock on the table, as appropriate.
After acquiring an X lock, assert that n_mysql_handles_opened == 1.
Remove the comments about dropping tables in the background.

ha_innobase::final_drop_index(): Acquire an X lock on the table.

dict_table_t: Remove version_number, to_be_dropped, and prebuilts.
ins_node_t: Remove table_version_number.

enum lock_mode: Move the definition from lock0lock.h to lock0types.h.

ROW_PREBUILT_OBSOLETE, row_update_prebuilt(), row_prebuilt_table_obsolete():

row_prebuilt_t: Remove the declaration from row0types.h.

6a6d7a9b09 branches/zip:
* Change terminology:
  wait lock -> requested lock
  waited lock -> blocking lock
  new: requesting transaction (the trx what owns the requested lock)
  new: blocking transaction (the trx that owns the blocking lock)

* Add transaction ids to INFORMATION_SCHEMA.INNODB_LOCK_WAITS. This is
  somewhat redundant because transaction ids can be found in INNODB_LOCKS
  (which can be joined with INNODB_LOCK_WAITS) but would help users to
  write shorter joins (one table less) in some cases where they want to
  find which transaction is blocking which.
