      branches/zip: trx_undo_prev_version_build(): Remove a bogus warning · 3ab0d2d1
      marko authored
      about undo_rec possibly being uninitialized.  When trx_undo_get_undo_rec()
      leaves undo_rec uninitialized, both functions will return DB_MISSING_HISTORY
      without dereferencing undo_rec.
      
      This closes Mantis issue #7.

      branches/zip: Hide some global variables that were accidentally not hidden · 468d425d
      marko authored
      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

      branches/zip: Make the changes to pars0grm.c that were promised in r2276. · fe5e0b72

      pars/pars0grm.h: Remove.  The primary file is include/pars0grm.h.
      
      pars/make_bison.sh: Add from trunk.  Somehow, this file was not merged
      at the same time with make_flex.sh.  Add sed magic for replacing the
      file name and for hiding yychars, yynerrs, yylval, and yyparse.
      
      pars/pars0grm.c: Apply the changes made by make_bison.sh.

      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.

      branches/zip: row_sel_get_clust_rec_for_mysql(): Similar to the function · 793b1fe3
      marko authored
      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.
