      FileStoragePacker: open the filestorage in unbuffered mode. Transactions · 3a7a90f6
      Tim Peters authored
      can still be in progress, and they're written to the same physical file via
      a different file object.  Using buffered I/O in the packer creates the
      possiblity for the packer to see stale data from its file object's stdio
      buffers.  This is now known to happen under Linux, Gentoo, OS X, Cygwin,
      and Debian.  It apparently doesn't happen under native Windows, which is
      why everyone except me has been seeing the new checkPackLotsWhileWriting
      test fail.
      
      This will probably need to be backported everywhere, but first I want to
      see in which new way checkPackLotsWhileWriting fails on 48 Linux boxes
      overnight <wink>.

      By popular demand, FileStorage.pack() no longer propagates a · 00f6abf3
      Tim Peters authored
          FileStorageError:  The database has already been packed to a
          later time or no changes have been made since the last pack
      
      exception.  Instead that message is logged (at INFO level), and
      the pack attempt simply returns then (no pack is performed).
      
      Incidentally, this should repair frequent reports of failure in the
      new checkPackLotsWhileWriting test.  On non-Windows systems, it
      seems that the worker thread often didn't get enough cycles to commit
      a change between the main thread's attempts to run pack() (and so
      the exception above got raised then).

      checkPackLotsWhileWriting: remove excess generality. Only one client · e15aeeca

      thread is interesting here, so removed the hair catering to the possiblity
      of N > 1 threads.

      Make _added_during_commit a regular instance variable.  Don't use
      try/finally to reset it; just clear it at the start of a transaction.
      XXX There was a test that needed to be removed, but it seemed to be
      just a shallow test that try/finally was used.  Can't see any feature
      that depends on specific of error handling: The txn is going to abort.
      
      Remove unused _opened instance variable.
      Split commit() into two smaller parts.
      Get rid of extra manipulation of _creating.
      Don't look for _p_serial of None; z64 is now required.
      Undo local variable aliases in subtransaction methods.
      
      Also, trivial change to pickle cache API -- get() works like dict get().

      New (but disabled for now) test checkPackLotsWhileWriting reliably dies · 4a6f51c1

          CorruptedError:  ... transaction with checkpoint flag set
      
      on my box when doing the ZEO flavor of FileStorage.  This is like the
      other pack-while-writing tests, but uses only 1 client thread that does
      twice as much, and packs repeatedly for so long as that thread runs.  I
      usually see it fail before the fourth pack attempt.
