mariadb/storage/maria/ma_rsame.c
unknown df843c4ce2 Fixed problems with ma_test2 and mi_test2 on high-byte-first system
Fixed bug in ma_test2 when last row in table is deleted
Fixed that ma_test_recovery.pl works on Solaris (by using digest instead of md5sum)
Fixed some compiler warnings generated by the Forte compiler


dbug/dbug.c:
  Added cast to get rid of compiler warning
mysys/lf_alloc-pin.c:
  Added cast to get rid of compiler warning
mysys/my_bitmap.c:
  Removed impossible DBUG_ASSERT()'s to get rid of compiler warnings
mysys/my_compress.c:
  Removed wrong cast to get rid of compiler warning
storage/maria/lockman.c:
  Added cast to get rid of compiler warning
storage/maria/ma_open.c:
  Added fix from MyISAM to allocate space in key buffer for nod pointer
storage/maria/ma_recovery.c:
  Fixed initialization that caused compiler warning
storage/maria/ma_rsame.c:
  More DBUG_PRINT
storage/maria/ma_scan.c:
  Better comment
storage/maria/ma_statrec.c:
  More DBUG_PRINT and comments
  Fixed indentation
BitKeeper/etc/ignore:
  added storage/maria/unittest/tmp/*
storage/maria/ma_test2.c:
  Fixed bug that caused maria_rsame() to fail if test removed last row
  Fixed wrong usage of longget();  Should be uint4korr()
storage/maria/unittest/ma_test_recovery.pl:
  Use md5sum or digest to calculate md5.
  This allows this script to be run on Linux and Solaris
storage/myisam/mi_test2.c:
  Fixed wrong usage of longget();  Should be uint4korr()
strings/ctype.c:
  Added casts to get rid of compiler warnings
sql-bench/myisam.cnf:
  New BitKeeper file ``sql-bench/myisam.cnf''
