XtraDB compile error with VS 10 64-bit

[Hakan Küçükyılmaz]

Compiling XtraDB with VS 2010 on 64-bit Windows fails with several errors all of the type:

Error 10 error C2440: 'initializing' : cannot convert from 'ulint *' to 'unsigned long *' C:\Users\hakan\work\monty_program\maria-5.2\storage\xtradb\handler\ha_innodb.cc 10410

The code in question is:

Error 10 error C2440: 'initializing' : cannot convert from 'ulint *' to 'unsigned long *' C:\Users\hakan\work\monty_program\maria-5.2\storage\xtradb\handler\ha_innodb.cc 10410

static MYSQL_SYSVAR_ULONG(use_purge_thread, srv_use_purge_thread,
  PLUGIN_VAR_RQCMDARG | PLUGIN_VAR_READONLY,
  "Number of purge devoted threads. #### over 1 is EXPERIMENTAL ####",
  NULL, NULL, 1, 0, 64, 0);

And line 10410 is
  NULL, NULL, 1, 0, 64, 0);

The problem is that xtradb tries to store a ulint using unsigned long. This works on all architecures except 64 bit Windows because ulint is defined as __int64 on that. There is currently no MYSQL_SYSVAR_xx that matches this, so I have added a MYSQL_SYSVAR_ULINT and changed the calls to this. See the attached patch.

[Bo Thorsen (bo.thorsen)]

New attempt at a patch. This one doesn't modify plugin.h but is local to xtradb.

[Bo Thorsen (bo.thorsen)]

Here is a smaller patch, which is the one I'll push to MariaDB.
