  Fix Bug#39939 DROP TABLE/DISCARD TABLESPACE takes long time in
  buf_LRU_invalidate_tablespace()

  Improve implementation of buf_LRU_invalidate_tablespace by attempting
  hash index drop in batches instead of doing it one by one.

  branches/5.1: ha_innobase::delete_all_rows(): In response to a user asking
  <http://forums.innodb.com/read.php?4,215,215> why DELETE FROM t is not
  mapped to TRUNCATE TABLE t as it is in MyISAM, note in a comment that
  DELETE is transactional while TRUNCATE is not.

0eff3d3ca6 branches/zip: Simplify the autoinc initialization code. This removes the
non-determinism related to reading the table's autoinc value for the first
time. This change has also reduced the sizeof dict_table_t by sizeof(ibool)
bytes because we don't need the dict_table_t::autoinc_inited field anymore.

This also fixes Bug#39830 Table autoinc value not updated on first insert.

  branches/5.1: Since handler::get_auto_increment() doesn't allow us
  to return the cause of failure we have to inform MySQL using the

  Fix Bug#39438 Testcase for Bug#39436 crashes on 5.1 in fil_space_get_latch
  
  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
  mysql-test case and thus this test innodb_bug39438 must be added to the
  list of exceptional test cases that are allowed to print warnings. For this,
  the following patch must be applied to the mysql source tree:

  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.

9bbd5454db branches/zip:
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.

      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.

4c37fb93be branches/zip:
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.

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>

    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.

	kilobytes (1, 2, 4, 8, or 16; default 8)

KEY_BLOCK_SIZE=1, 2, 4, 8, or 16: implies ROW_FORMAT=COMPRESSED;
ignored if ROW_FORMAT is not COMPRESSED

KEY_BLOCK_SIZE=anything else: ignored

The InnoDB row format is displayed in the 4th column (Row_format) of
the output of SHOW TABLE STATUS.  The Create_options column may show
ROW_FORMAT= and KEY_BLOCK_SIZE=, but they do not necessarily have
anything to do with InnoDB.

The table format can also be queried like this:

SELECT table_schema, table_name, row_format
FROM information_schema.tables
WHERE engine='innodb' and row_format in ('Compressed','Dynamic');

When Row_format='Compressed', KEY_BLOCK_SIZE should usually correspond
to the compressed page size.  But the .frm file could be manipulated
to show any KEY_BLOCK_SIZE.

For some reason, INFORMATION_SCHEMA.TABLES.CREATE_OPTIONS does not
include KEY_BLOCK_SIZE.  It does include row_format (spelled in
lowercase).  This looks like a MySQL bug, because the table
INFORMATION_SCHEMA.TABLES probably tries to replace SHOW TABLE STATUS.
I reported this as Bug #35275 <http://bugs.mysql.com/35275>.

ha_innobase::get_row_type(): Add ROW_TYPE_COMPRESSED, ROW_TYPE_DYNAMIC.

ha_innobase::create(): Implement ROW_FORMAT=COMPRESSED and
ROW_FORMAT=DYNAMIC.  Do not throw errors for wrong ROW_FORMAT or
KEY_BLOCK_SIZE, but issue warnings instead.

ha_innobase::check_if_incompatible_data(): Return COMPATIBLE_DATA_NO
if KEY_BLOCK_SIZE has been specified.

innodb.result: Adjust the result for the warning issued for ROW_FORMAT=FIXED.

innodb-zip.test: Add tests.  Query INFORMATION_SCHEMA.TABLES for ROW_FORMAT.

86361e032b branches/zip: Implement the configuration parameter and settable global
variable innodb_file_format.  Implement file format version stamping of
*.ibd files and SYS_TABLES.TYPE.

This change breaks introduces an incompatible change for for
compressed tables.  We can do this, as we have not released yet.

innodb-zip.test: Add tests for stricter KEY_BLOCK_SIZE and ROW_FORMAT
checks.

DICT_TF_COMPRESSED_MASK, DICT_TF_COMPRESSED_SHIFT: Replace with
DICT_TF_ZSSIZE_MASK, DICT_TF_ZSSIZE_SHIFT.

DICT_TF_FORMAT_MASK, DICT_TF_FORMAT_SHIFT, DICT_TF_FORMAT_51,
DICT_TF_FORMAT_ZIP: File format version, stored in table->flags,
in the .ibd file header, and in SYS_TABLES.TYPE.

dict_create_sys_tables_tuple(): Write the table flags to SYS_TABLES.TYPE
if the format is at least DICT_TF_FORMAT_ZIP.  For old formats
(DICT_TF_FORMAT_51), write DICT_TABLE_ORDINARY as the table type.

DB_TABLE_ZIP_NO_IBD: Remove the error code.  The error handling is done
in ha_innodb.cc; as a failsafe measure, dict_build_table_def_step() will
silently clear the compression and format flags instead of returning this
error.

dict_mem_table_create(): Assert that no extra bits are set in the flags.

dict_sys_tables_get_zip_size(): Rename to dict_sys_tables_get_flags().
Check all flag bits, and return ULINT_UNDEFINED if the combination is
unsupported.

dict_boot(): Document the SYS_TABLES columns N_COLS and TYPE.

dict_table_get_format(), dict_table_set_format(),
dict_table_flags_to_zip_size(): New accessors to table->flags.

dtuple_convert_big_rec(): Introduce the auxiliary variables
local_len, local_prefix_len.  Store a 768-byte prefix locally
if the file format is less than DICT_TF_FORMAT_ZIP.

dtuple_convert_back_big_rec(): Restore the columns.

srv_file_format: New variable: innodb_file_format.

fil_create_new_single_table_tablespace(): Replace the parameter zip_size
with table->flags.

fil_open_single_table_tablespace(): Replace the parameter zip_size_in_k
with table->flags.  Check the flags.

fil_space_struct, fil_space_create(), fil_op_write_log():
Replace zip_size with flags.

fil_node_open_file(): Note a TODO item for InnoDB Hot Backup.
Check that the tablespace flags match.

fil_space_get_zip_size(): Rename to fil_space_get_flags().  Add a
wrapper for fil_space_get_zip_size().

fsp_header_get_flags(): New function.

fsp_header_init_fields(): Replace zip_size with flags.

FSP_SPACE_FLAGS: New name for the tablespace flags.  This field used
to be called FSP_PAGE_ZIP_SIZE, or FSP_LOWEST_NO_WRITE.  It has always
been written as 0 in MySQL/InnoDB versions 4.1 to 5.1.

MLOG_ZIP_FILE_CREATE: Rename to MLOG_FILE_CREATE2.  Add a 32-bit
parameter for the tablespace flags.

ha_innobase::create(): Check the table attributes ROW_FORMAT and
KEY_BLOCK_SIZE.  Issue errors if they are inappropriate, or warnings
if the inherited attributes (in ALTER TABLE) will be ignored.

PAGE_ZIP_MIN_SIZE_SHIFT: New constant: the 2-logarithm of PAGE_ZIP_MIN_SIZE.

c853494ea2 branches/zip: Make innodb_file_per_table a settable global variable.
There is one consideration: fil_init() chooses the tablespace hash size
based on the initial value of srv_file_per_table.  However, this is nothing
new: InnoDB could be started with innodb_file_per_table=0 even though
*.ibd files exist.

srv_file_per_table: Declare as my_bool instead of ibool, because
MYSQL_SYSVAR_BOOL() expects a pointer to my_bool.  Document the
variable also in srv0srv.h.

innobase_start_or_create_for_mysql(): Note why it is OK to temporarily
clear srv_file_per_table.

innobase_file_per_table: Remove.

149298b7ac branches/zip: row_raw_format_str_convert(): Rename to
innobase_raw_format(), move the definition from row0row.c to 
ha_innodb.cc. After this change, row0row.c no longer references 
system_charset_info (Mantis issue #17). Patch prepared by Vasil, 
tested by Calvin, and reviewed by Marko.

26402257da branches/zip:
Use innobase_strcasecmp() insteaed of strcasecmp() in i_s.cc and get rid
of strings.h (that file is not present on Windows).

Move the prototype of innobase_strcasecmp() from ha_innodb.cc and
dict0dict.c to ha_prototypes.h.

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.
