      A better solution would be to define a const_page_cur_t and a

      marko authored
      The size of the buffer pool can be one page smaller than the requested
      size when os_mem_alloc_large() returns something that is not
      aligned by UNIV_PAGE_SIZE.  This test may still fail on systems with
      a big os_large_page_size.

      branches/zip: Allow a dynamically loaded InnoDB storage engine plugin · 15e0e266
      marko authored
      to replace a built-in instance of InnoDB in mysqld.  This is work in
      progress, with several limitations:
      
      * Other plugins defined in the builtin InnoDB are not disabled.
        However, InnoDB in MySQL 5.1 only defines the storage engine plugin,
        no INFORMATION_SCHEMA plugins.
      
      * The global C symbols in ha_innodb.so except innodb_hton_ptr and
        builtin_innobase_plugin will have to be redefined, e.g., by objcopy.
      
      * The storage engine cannot be called "InnoDB" to avoid a conflict with
        the builtin name.  Here we call it InnoDBzip.
      
      innobase_hton_name[]: Rename to "InnoDBzip" when building a dynamic plugin.
      
      innodb_plugin_init(): New function for the dynamic plugin, to copy
      and redirect configuration parameters from the builtin InnoDB.
      
      innodb_dynamic: New configuration parameter.  This has to be added
      to the builtin InnoDB in MySQL 5.1.  Also, innodb_hton_ptr must be made
      global there.
      
      innobase_init(): Interpret the parameter innodb_dynamic.
      
      Makefile.am: Redefine class ha_innobase to ha_innodb by a preprocessor
      define.  Apparently, C++ classes cannot be easily renamed by objcopy.

      branches/zip: innodb-index.result: Adapt the results to a patch from MySQL. · dcde0edf
      marko authored
      Unfortunately, the patch seems to prevent MySQL from utilizing secondary
      indexes in the ORDER BY clauses.  Thus, the test no longer checks if newly
      created indexes are well-formed.
      
      ChangeSet@1.2528.98.1  2007-08-02 12:45:56-07:00  igor@mysql.com
      
      Fixed bug#28404.
      This patch adds cost estimation for the queries with ORDER BY / GROUP BY
      and LIMIT. 
      If there was a ref/range access to the table whose rows were required
      to be ordered in the result set the optimizer always employed this access
      though a scan by a different index that was compatible with the required 
      order could be cheaper to produce the first L rows of the result set.
      Now for such queries the optimizer makes a choice between the cheapest
      ref/range accesses not compatible with the given order and index scans
      compatible with it.
