classified as a simple INSERT. For REPLACE statements we don't acquire
the special AUTOINC lock for AUTOINC_NEW_STYLE_LOCKING with this fix.

Fix Bug#36819 ut_usectime does not handle errors from gettimeofday

by retrying gettimeofday() several times if it fails in ut_usectime().
If it fails on all calls then return error to the caller to be handled
at higher level.

Update the variable innodb_row_lock_time_max in SHOW STATUS output only
if ut_usectime() was successful.

Fix Bug#11894 innodb_file_per_table crashes w/ Windows .sym symbolic
link hack

The crash was due to un-handled error 3 (path not found). In the case
of file per table, change the call to os_file_handle_error_no_exit()
from os_file_handle_error(). Also, checks for full path pattern during
table create (Windows only), which is used in symbolic link and temp
table creation.

    Use pkglibdir to simplify pkgplugindir, and fix the path in a
    couple of Makefiles.  Continuation of the fix for bug#31736.

Add vim modeline to hint it that plug.in is a config file
so it can be colorized.

Non-functional change: use tabs for indentation in plug.in.

Fix r2430, it should be CFLAGS="$CFLAGS ..." not CFLAGS="..."

Use CFLAGS instead of INNODB_CFLAGS to avoid having incompatible flags
inserted in CFLAGS and INNODB_CFLAGS and to avoid compiling mysql and
innodb with different flags.

Discussed with:	Sunny

* Use INNODB_CFLAGS insead of cluttering CFLAGS with InnoDB specific
  flags. CFLAGS are used to compile every file in the MySQL source tree.

* Add INNODB_DYNAMIC_CFLAGS to the flags of the dynamic plugin and use
  -prefer-non-pic to make the dynamic plugin faster on i386.

Fix Bug#36169 create innodb compressed table with too large row size crashed

Sometimes it is possible that
row_drop_table_for_mysql(index->table_name, trx, FALSE); is invoked in
row_create_index_for_mysql() when the index object is freed so copy the
table name to a safe place beforehand and use the copy.

and handler_delete

Add the calls to ha_statistic_increment() in ha_innobase::delete_row()
and ha_innobase::update_row().

In InnoDB, the row count is only a rough estimate used by SQL
optimization. InnoDB is now return row count 0 for TRUNCATE operation.

INFORMATION_SCHEMA.TABLES.DATA_FREE.

Swap the order in which mysql_thd, mysql_query_str and *mysql_query_str
are checked for non-NULL.

Suggested by:	Marko

Check whether *trx->mysql_query_str is != NULL in addition to
trx->mysql_query_str. This adds more safety.

  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.

Fix Bug#34300 Tinyblob & tinytext fields currupted after export/import and alter in 5.1

Copy the BLOB fields, that are stored internally, to a safe place
(prebuilt->blob_heap) when converting a row from InnoDB format to
MySQL format in row_sel_store_mysql_rec().

The bug was introduced in:

 Optimize BLOB selects by using prebuilt->blob_heap directly instead of first
 reading BLOB data to a temporary heap and then copying it to
 prebuilt->blob_heap.

the size of the UNDO slots cache lists (insert and upate). If either of
cached lists has more than 500 entries then we add any UNDO slots that are
freed, to the common free list instead of the cache list, this is to avoid
the case where all the free slots end up in only one of the lists on startup
after a crash.

Tested with test case for 26590 and passes all mysql-test(s).

 
Fix Bug#34823:

This is a combination of changes that forward port the scalability fix applied to 5.0
through r1001.
It reverts changes r149 and r122 (these were 5.1 specific changes made in lieu of
scalability fix of 5.0)
Then it applies r1001 to 5.0 which is the original scalability fix.
Finally it applies r2082 which fixes an issue with the original fix.
