Send storage size info to all clients at end of pack and
commit.

understandable.

Sped up startup a tiny bit by not doing synchronous get_info call on
startup. Instead, server will send info asynchrously on startup.

to avoid a security problem arising from the way that Zope
changes the effective user id. The first cache file gets created while
Zope is root, so it can't be reopened as nobody.

mechanism is messed up. In this case, we just close the connection,
which will ultimately cause us to reconnect.

This is important since storea is an asynchronous routine.

- Return error is we get a begin request from a connection that
  already has an active transaction.

- Log connections and disconnection logging. Someone (Sam) decided to
  comment this out of the asyncore code.

- Include connection id in debugging messages.

the connection to the storage server is disconnected.

as root on Unix.

Added a signal handler to (gracefully) close storages when killed.
This causes FileStorages to get their indexes written.

and notification propagation, but i got carried away and tried to fill
in some pieces otherwise slightly mysterious to me...

storing serial numbers in the temporary file holding local transaction
data.

Also added error check in temporary file management to detect
unexpected end-of-file conditions.

the trunk. :(

The bug caused pack to missadjust backward file pointers
in some cases involving versions and undo.

tempfiles do *not* perpetually accumulate.  (TemporaryFile reliably is
removed when the program is done with it, under both windows and
unix.)

ClientCache.__init__(): Set up the first TemporaryFile, and set both
self._p file names to None, to signify use of temp files.

ClientCache.checkSize(): Switch over to other persistent cache file if
self._p has names, or a new TemporaryFile if they're None.

(I included some comments to the code i touched, to ease the passage
of anyone else who winds up on that path...)

for versions when non-version data was committed.


Fixed bug in invalidation of objects that were committed from one
version to another. The objects were not invalidated in the old version.

methods.

Added logic to handle case where object *only* has version data.

Made debug logging a tad more verbose.

Errors in pickling exceptions were misshandled, causing the server
to fail.

when server comes back.

Fixed totallu broken 'versions', 'commitVersion', and 'abortVersion'
methods.

Added logic to handle case where object *only* has version data.

Fixed bug in handling of data for objects created in a version
(for which there is no non-version data).

server to implement vote correctly.
