      Turn off MUCH_RING_CHECKING. · 1cb93e7d
      Jeremy Hylton authored
      I think it's safe to run this code without extra checking.

      Add a bunch more tests of the LRU cache mechanism and of DB methods. · 43fa28e3

      Remove the cache_deactivate_after argument from the cPickleCache · 8007802d
      Jeremy Hylton authored
      constructor, since it is ignored and there is no current plan to
      support two caches with almost-but-not-quite-the-same arguments.
      
      This change has effects in many files.  The Connection and DB don't
      pass this argument and don't bother setting it explicitly when it is
      reset via DB APIs like setCacheDeactivateAfter().  XXX These APIs
      remain, since existing code may depend on them, but they have no
      effect.
      
      New policy in cPersistence.c: A Persistent object can't have its
      _p_jar set or deleted once it is in a cache.  Persistent already
      implemented this policy for _p_oid; it seems safer to do the same for
      the jar.
      
      Add ringlen() method to cache objects (implemented as cc_ringlen).
      This returns the length of the doubly linked list of non-ghost
      objects.  Same as len(cache.lru_items()), but more efficient.  Only
      used for testing at the moment.
      
      In ring_corrupt(), don't raise a new exception if one has already been
      set.  The old behavior masked useful information about the original
      error / traceback.

      Sundry changes. · 046da4a8
      Jeremy Hylton authored
      Implement behavior for minimize() and full_sweep() as discussed on
      zodb-dev.  minimize() ghostifies all unmodified objects.  full_sweep()
      with age==0 is the same as minimize(), otherwise it's the same as
      incrgc().
      
      Reformat and/or reindent lots of code.
      
      Use PyObject_Compare() instead of PyObject_Cmp() because it has a
      simpler return value.
      
      Fix a few more PyDict_SetItem() and PyDict_DelItem() calls to make
      correct check for error return.

      Refactor the commit() method. · 56ab4405
      Jeremy Hylton authored
      Break up the logic into a bunch of helper methods:
       _commit_objects()
       _commit_subtrans()
       _finish_one()
       _finish_rest()
      and possibly
       _commit_error()
      
      As a result of the changes, the high-level logic of a commit fits into
      28 lines inside a try/finally.  There are lots of details hidden in
      the methods, but the names capture the high-level behavior of the
      helpers.

      Wrap abort_sub() call in try/except that logs exception and continues. · 722fc658
      Jeremy Hylton authored
      This fixes the transient failure in testExceptionInSubAbortSub() and
      is presumed to be correct, too.  The old code had the comment:
          # This should never fail
      but did not to guarantee that it never failed.  I'm assuming that the
      write fix is to log the error and ignore it, because that's what the
      call to tpc_abort() immediately above does.
      
      XXX commit() is a really long method.  It would be nice to break it up
      into easier-to-understand chunks.

      Move cc_oid_unreferenced() into the C API and out of Python. · 75ee5c7a
      Jeremy Hylton authored
          The rationale is that this is an internal detail of the cache
          implementation called by Per_dealloc().  It's nice to make it
          fast, and it's good to prevent it from being called with anything
          other than an about-to-be-freed object.
      
          As a result of it being in the C API, omit tests of refcounts.  We
          would have been in Per_dealloc() otherwise.
      
          Initialize the percachdel slot of cPersistenceAPIstruct to NULL in
          cPersistence.  In cPickleCache, import the CObject and fill in the
          struct.
      
      Also, reformat many of the comments so that all the text starts to the
      right of the /*.
      
      Fiddle the text of the placeholder comment.  I think I understand it
      now :-).
      
      Add an XXX comment about the "old" cache API e.g. fullsweep and
      reallyfullsweep.
      
      Fix cc_get().  object_from_oid() doesn't ever set an exception.
      
      Remove a Py_FatalError() check from the end of a module init
      function.  We don't do that anymore.
