(lockmanager still fails unit tests)


BitKeeper/deleted/.del-Makefile.am~4375ae3d4de2bdf0:
  Delete: unittest/maria/Makefile.am
configure.in:
  silence up configure warnings, don't generate unittest/maria/Makefile

include/atomic/x86-gcc.h:
  s/LOCK/LOCK_prefix/
include/atomic/x86-msvc.h:
  s/LOCK/LOCK_prefix/
include/lf.h:
  pin asserts, renames
include/my_atomic.h:
  move cleanup
include/my_bit.h:
  s/uint/uint32/
mysys/lf_dynarray.c:
  style fixes, split for() in two, remove if()s
mysys/lf_hash.c:
  renames, minor fixes
mysys/my_atomic.c:
  run-time assert -> compile-time assert
storage/maria/Makefile.am:
  lockman here
storage/maria/unittest/Makefile.am:
  new unit tests
storage/maria/unittest/trnman-t.c:
  lots of changes
storage/maria/lockman.c:
  many changes:
  second meaning of "blocker"
  portability: s/gettimeofday/my_getsystime/
  move mutex/cond out of LOCK_OWNER - it creates a race condition
  that will be fixed in a separate changeset
  increment lm->count for every element, not only for distinct ones -
  because we cannot decrease it for distinct elements only :(
storage/maria/lockman.h:
  move mutex/cond out of LOCK_OWNER
storage/maria/trnman.c:
  move mutex/cond out of LOCK_OWNER
  atomic-ops to access short_trid_to_trn[]
