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.

  unaccessible because they start with an underscore.

- Add a test suite for the Tree.py module.

string of setChildAccess. This is quite different from the old
implementation, but as that old implementation never worked anyway, this
change won't break any code elsewhere.

as endoded node ids can start with a '.' as well. Also more rigorously test
for an encoded depth when decoding.

- SimpleTree could not build a tree from anything but the ZODB root object,
  because the REQUEST object could no longer be acquired once a tree root object
  was wrapped inside a tree node class.

- TreeMaker.setChildAccess(filter=...) didn't work because the acquisition
  filter used was using too many arguments.

Also, sort imports alphabetically.
