  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.

  innodb_bug36169.test: Ensure that none of the tables can be created.

  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

  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:

  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

    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.

  branches/zip:

  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

  branches/zip: ha_innobase::create(): Remove the dependences on
  DICT_TF_ZSSIZE_MAX, so that the code can be compiled with a different
  uncompressed page size by redefining UNIV_PAGE_SIZE_SHIFT in univ.i.
  Currently, the allowed values are 12, 13, or 14 (4k, 8k, 16k).

  Make the default compressed page size half the uncompressed page size.
  The previous default was 8 kilobytes, which is the same when compiling
  with the default 16k uncompressed page size.

  trx_sys_file_format_max_upgrade(): Rename from
  trx_sys_file_format_max_update().  Improve the documentation.  Add a
  const qualifier to the parameter "name".  Replace the parameter
  "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.

  branches/zip: Skip the undo log size check on REDUNDANT and COMPACT tables.

  In ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPRESSED, column prefix indexes
  require that prefixes of externally stored columns be written to the
  undo log. This may make the undo log record bigger than the record on
  the B-tree page.  The maximum size of an undo log record is the page
  size.  That must be checked for, in dict_index_add_to_cache().

  dict_index_add_to_cache(): Skip the undo log size check for REDUNDANT
  and COMPACT tables. These tables store prefixes of externally stored
  columns locally within the clustered index record.  There are no special
  considerations for the undo log record size.

  innodb-index.test: Ensure that the check exists for ROW_FORMAT=DYNAMIC,
  but not for ROW_FORMAT=COMPACT.

  This fixes issue #99.  rb://28 approved by Sunny.

  branches/zip: When the server crashes while freeing an externally stored
  column of a compressed table, the BTR_EXTERN_LEN field in the BLOB pointer
  will be written as 0.  Tolerate this in the functions that deal with
  externally stored columns.  This fixes Issue #80 and was posted at rb://26.

  Note that the clustered index record is always deleted or purged last,
  after any secondary index records referring to it have been deleted.

  btr_free_externally_stored_field(): On an uncompressed table, zero out
  the BTR_EXTERN_LEN, so that half-deleted BLOBs can be detected after
  crash recovery.

  btr_copy_externally_stored_field_prefix(): Return 0 if the BLOB has been
  half-deleted.

  row_upd_ext_fetch(): Assert that the externally stored column exists.

  row_ext_cache_fill(): Allow btr_copy_externally_stored_field_prefix()
  to return 0.

  row_sel_sec_rec_is_for_blob(): Return FALSE if the BLOB has been half-deleted.
  This is correct, because the clustered index record would have been deleted
  or purged last, after any secondary index records referring to it had been
  deleted.

2c2b06ad75 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.

previous versions of the row.

innodb-zip.test: New file, for tests of the compression.

upd_field_t: Add orig_len, the original length of new_val.

btr_push_update_extern_fields(): Restore the original prefix of the column.
Add the parameter heap where memory will be allocated if necessary.

trx_undo_rec_get_col_val(): Add the output parameter orig_len.

trx_undo_page_report_modify_ext(): New function: Write an externally
stored column to the undo log.  This is only called from
trx_undo_page_report_modify(), and this is the only caller of
trx_undo_page_fetch_ext().

trx_undo_update_rec_get_update(): Read the original length of the column
prefix to upd_field->orig_len.

3152fe562c branches/zip: row_sel_get_clust_rec_for_mysql(): Similar to the function
row_sel_get_clust_rec(), return if a previous version of the clustered index
record does not exist in the read view.  This bug was made and found by
Heikki.  It was harmless as long as the clustered index record contained
a long enough local prefix of externally stored columns, to allow secondary
index records to be built without fetching BLOBs.

InnoDB transactions should never look at a clustered index record whose
transaction identifier (DB_TRX_ID) is not visible in the transaction's
read view.

d0d9299177 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.

was added to the background drop queue.

938774502a branches/zip: When logging updates or deletes in the undo log, store long
enough prefixes of externally stored columns, so that purge will not have
to dereference any BLOB pointers, which may be invalid.  This will not be
necessary for logging inserts, because inserts are no-ops in purge, and
the record will remain locked during transaction rollback.

TODO: in dict_build_table_def_step() or dict_build_index_def_step(),
prevent the creation of tables with too many columns for which a
prefix index is defined.  This is because there is a size limit of undo
log records, and for each prefix-indexed column, the log must store
REC_MAX_INDEX_COL_LEN + BTR_EXTERN_FIELD_REF_SIZE bytes.

trx_undo_page_report_insert(): Assert that the index is clustered.

trx_undo_page_fetch_ext(): New function, for fetching the BLOB prefix
in trx_undo_page_report_modify().

trx_undo_page_report_modify(): Write long enough prefixes of the externally
stored columns to the undo log.

trx_undo_rec_get_partial_row(): Remove the parameter "ext".  Assert that
the undo log contains long enough prefixes of the externally stored columns.
