getId.  This is a change designed to make it possible to disambiguate user names and user ids in subclasses of user folders, while still doing the "right thing" with respect to local data structures that keep pointers to user ids (eg. local roles, etc.)

Zope tree every time the DAV Lock Manager control panel is visited, it
gives the user a chance to specify a path to start from, shortening
query times (especially in large databases).

PageTemplateFiles were previously owned by whatever object contained
them.  This resulted in very hard bugs if the user who owned the
container was removed.  Since PageTemplateFiles come from the
filesystem, they are now "unowned", similar to DTMLFiles.  Security is
still applied, but now it is applied correctly.

Ahem, *cough*: "Please run the test suite before checking in a change! At
the very least run the tests for the package you changed."

Date is a required header in RFC822 and RFC2822, so MailHost now adds it if it doesn't exist.

Note that I'm not sure the pids written to the pidfile always make
sense.

in addition to the loads and stores.

as pruning of old no longer existing modules).

when it caught a signal related to any of these signal numbers. ;-)  Instead, it
actually tries now to kill its child process with the same signal.

Pidfile handling improved.

When Zope is started under zdaemon, it no longer writes its own pidfile.  Instead, it passes in the path to Z2.pid to zdaemon as its pidfile name.  The 'zProcessManager.pid' file is no longer ever written.

This caused a change to the -Z option of z2.py which should be mostly backwards-compatible (unless people were relying on zProcessManager.pid to be written).  Now the -Z option is a boolean.  -Z1 means use a daemon.  -Z0 means dont.  The default is -Z1.

Write pidfiles out with trailing newlines.

Minor reorganization of "SignalPasser" code (move it from its own module into zdaemon).

is not authenticated to access. However, any custom filter set through
setChildAccess was getting the unfiltered list of child nodes. Change this
so a filtered list of nodes s handed to the custom filter.

Modified the translation service to return None if no translation exist.
So now using i18n tags without a translation service should give the
same behavior as before. The tests reflect that.

requires.

- Refactor tree method to allow callback function (set with
  setStateFunction) to influence node state.

- hasChildren now stores the result of getChildren in a local cache, which
  getChildren uses and clears on a subsequent call. This was needed to avoid
  generating the children list for open nodes twice.

- hasChildren now flattens its return value to a boolean; tree relies on
  this.
