Hack os.rename rather than the blob to avoid a testing artifact in the blob implementation.

Jim Fulton authored
- Unwritten blobs can now be read, and are empty. - Blobs are considered modified when opened for writing. This is a little bit more conservative than before but fixes a bug that a file opened with 'w' actually does modify the file and wasn't considered to be a change before. - Optimistic savepoints now work. - Fixed bug: could open multiple files for writing. - Fixed bug: aborting a transaction removed uncommitted data for uncommitted blobs. Todo: Need to remove uncommitted data file if a blob is GCed even when a transaction isn't aborted or when it hasn't been added to anything. - No-longer close files on transaction boundaries. This allows us to get rid of the transaction-manager dance.

object is a blob. YAGNI support for multiple blob implementations -- at least for now.

away -- even before they are placed in the cache. This causes a problem if the object's state has a (direct or indirect) reference to it. Added a pre-cache that allows the connection to return objects alreadey being loaded when necessary.

- Avoid more than one round-trip call when loading blobs via copy from the server. - Avoid loading large amounts of blob data into memory. The old storeBlob implementation was likely to queue blob adta faster than it could be sent, leading to a large memory foot print for the queue. Now, iterators are used to read data from files only when the network layer is ready to send it. - Fixed storeBlob to move the input file to the blob cache (when not sharing the blob directiry with the server). - Extended the loadBlob locking model to work with multiple processes by using file locks rather than threading locks. A common configuration is to use a client process per core, so that a machine is likely to have many client processes and it should be possible for the client processes to share a common blob cache.

Now it also truly consumes files. Binary mode is implicit.

Added a temporaryDirectory method for getting a directory to use for creating temporary files.

- Found and added a test for a race condition arising from creating and removing lock files. - Change to leave lock files behind. - Use the windows locking implementation from msvcrt from the standard library, rather than using a custom extension module.

simplify the code a little. (We'll be able to simplify more when we stop supporting versions.) Suppress version-deprecation warnings for tests.
