Restored behavior of ZCatalog when arguments with empty string are passed in. These values are effectively ignored by searchResults. If only empty values are passed, then it returns all results (assuming you passed an empty filter).

Removed "optimize" argument which was an attempt to "fix" searchResults for programmatic use. Also replaced comments this optimized behavior.

Eventually a new API will be added for "explicit" programmatic queries, for now we will suffer along with searchResults as it is. Extending it with additional dwim is not a path worth traveling.

although TemporaryStorage does not actually support versions.

"bareword" except: pass in a try: statement.  It now writes
a log message before passing.

_apply_index or index_object.

Fixed and added test cases to unittests.

parameter like "description:test" where test is a codec that's
apparently registered but not found.

(description:test was actually a typo in CMF's topic_editTopic.py)

The placement of the return for showEntry was preventing the error from being copied to the event log, even if the user had chosen to enable copying to the event log.

  * Collector #446 - Index managment permissions fixed

  * Index managment ui is now integrated into ZCatalog rather than being
    a tab leading to the Indexes subobject manage_main

ZCTextIndex fixed to work under this management scheme and now can be instantiated without that silly "extra" record thingy.

Updated Overview managment screen so it shows more info about the index.

"python setup.py build_ext -i" works.  This is only temporary... I'm
waiting for Matt Behrens to replace it with his complete setup.py.

weightedIntersection.

Added ability for site error log to return the url to the log entry and pass it to the standard_error_message to make a link from it.

reason for it not being enabled before.

chain for its transient object container.

Changed session data manager to splice itself into the transient
object container's acquisition path before returning a session
data object via getSessionData.

Updated unit tests to reflect changes.

returning X, contradicting the docs and common sense.
difference(None, X) continues to return None.

- removed obsolete code trying to deal with a trailing 'L' for longs

Changes:

 - More stable under high usage, especially in the face of
   situations under which there are many ZODB conflict
   errors. The previous implementation had stability problems
   when many conflict errors were encountered; especially
   conflicts that were generated as a result of a simultaneous
   change to a subobject of the TOC (such as in the case of a Zope
   application which makes heavy use of both frames and
   sessions).

 - More conflict-resistant.  Instead of ignoring the likelihood
   that multiple threads will attempt to perform the same actions
   simultaneously in methods of the TOC (which often causes
   conflicts), the new implementation attempts to avoid conflicts
   by employing a chance-based housekeeping model.  In this model,
   one thread is "elected" by chance to do the kinds of tasks that
   cause the most conflicts.

 - Now uses a "timeslice" based model instead of a "ring" based
   model.  This also helps cut down on conflicts and makes
   the code slighly less obfuscated (not much, though! ;-)

 - Quite a few more comments in the code.

 - Changes to the sessioning stresstest (which exposed the
   bug that made me reimplement the TOC in the first place).

 - Updates to unit tests.

 - A "HowTransienceWorks.stx" document which attempts to
   explain how the code works.  It's not stellar, but
   it's a start.

 - Changes to the TransientObject class that the TOC
   hands out (typically as a "session data object"), in order
   to make invalidation less Rube-Goldberg-ish.

The structure of the TOC object has changed enough that in order to
maintain b/w compatibility, an in-place upgrade of "old" instances
is implied by running them with this code.   "Upgraded" instances
are not backwards-incompatible, however, so folks can hopefully
move back and forth between Zope versions without much hassle.
