- logging an error message instead of raising an exception in case of
  unindex_object() failure

      - Collector #699: MailHosts created in 2.5 breaks in 2.6.

      - Collector #694: dtml-sendmail mailto specification replaces "To:" header.

Normalize whitespace (horizontal and vertical).

confusion caused by having the instance and the class have the same

ChrisM's changes here) it is no longer necessary to call
zLOG.initialize() in order to see logging output.

least 2.2.2.)

Add -v1 to TESTOPTS, so running the entire test suite is a little less
verbose.

Stringify the object in the exception in case its a list or tuple (an inscrutable error occurs if this is not done).

_doclose() twice (runsvr.py had a bug that caused the storages to be
closed twice).

Allowing DA to have an option connection hook which allows you to change the database connection at run time for a sqlmethod.

close(): The base class can now do all the work of closing, including
stopping the background threads.

log(): Much more convenient.

  severity level.  This allows the common names to be used for
  severities, not just integers.  This can make configuration data
  less obscure.

- Refactor initialize():
  get_environment_info() pulls information from the environment
  variables, and this gets passed to initialize_log(), which does
  nothing to determine the source of the configuration data.

- New method initialize_with_config():  Load information not provided
  by the environment from a ZConfig section.  This allows the
  environment to override a config file, and avoids having the
  application deal with the specific information needed to configure
  logging.

Jim suggests that autopack never do a full gc'ing pack by default, so
let's set the classicpack default to zero.

__init__(): Pass the absolute path to the DB environment's db_home  as
the name argument to the base class constructor.  This gives a unique
value for sortKeys().

env_from_string(): Keith Bostic suggests we stick with DB_RECOVER.

applied to ttheir modules.

When trusted code or module refreshes ask for a ModuleSecurityInfo object
that was already applied, previously a new one would be created, including
new ones for the parent packages. This could cause declartion for *other*
packages to be removed when this new Info object is reapplied later on.

Change one final use of the old regex module to ts_regex.

I would have expected "someone" to have removed it by now.

just slows the tests down (because we might have to wait up to 10
seconds for the thread to cleanly exit).

BerkeleyTestBase, one of the base classes is superfluous.

FullOpenCloseTest: New class to make sure that the checkpointing

DB_QUEUE tables.

close(): We can really simplify this and make it more robust for when
we add new tables, by relying on the fact that the base class
maintains its own list of opened tables, and the base class close()
method closes them in turn.

autopack(): Default the gc argument to False.

_collect_objs(), _mark(), _sweep(): Add an escape hatch for the pack
operation inside the inner loops of each of these methods.  That way,
we don't have to wait until the loops are finished to exit the pack
operation, if stop() has been requested by the main thread.

_Autopack: Use the _WorkThread base class.

the mark phase and during the sweep phase.  But this doesn't play
nicely with the escape hatch for pack, since if we raise a PackStop,
it's fine if we truncate the mark queue but not if we truncate the
sweep queue.  So the latter is now separated into the delqueue table.

Also, use the new extended _setupDB() arguments for the DB_QUEUE
tables.
