XXX The deferred name isn't perfect, but async is already taken.

When a block transaction is stopped because the client disconnects,
log a message at INFO level.

Add a message at BLATHER level when a transaction acquires the commit
lock.

- Cache the translations from severity to level and string in dicts,
  so these are normally done with a single dict.get() call rather than
  a Python function call.

- Extract the PEP 282 level first, and check it against the effective
  level of the logger, so we can take an early exit if the logger
  won't handle the event.

- Got rid of textwrap.  It slows things down, can frustrate grepping
  programs, and wasn't effective unless you were using Python 2.3
  anyway.

- Got rid of the addHandler(NullHandler()) (seems like superstition).

- Got rid of the log_format class variable (YAGNI).

the schema component library.  (The facility itself still needs to be
documented.)

The strategy classes stopped being useful, because the code had been
modified to always use one of the strategies.  The classes were left
behind because editing the code to use a single class was too much
work at the time.

Move all the logic back into ZEOStorage.  Rename non-public methods on
the class to start with _.  Use lambda: rather than getattr()() to
invoke the method that gets delayed waiting for the storage lock.

XXX Need to settle on a good name for this var and make sure the
schema and code agree on it.

- add a simple example of basic usage that should satisfy many
  applications

possibly being removed in the future.

There's now concrete test of recursively defined section types.

implemented.

available or not, and also fixes to all the tests so they won't crap
out or complain if not.

To test whether these storages are avialable (including all package
dependencies), do:

import BDBStorage
if BDBStorage.is_available:
    # okay to use

Also, in BDBStorage/__init__.py do some cross-platform compatibility
for the bsddb module; in Python 2.3 we can just use the built-in
module, but in earlier Pythons we have to use bsddb3.  Now you can
just use "from BDBStorage import db" to get the proper db object.

that OIDs are required to be strings, but AdaptableStorage permits any
length, and so might other storages.

- Renamed most files (especially python modules) to lower case.

- Moved views and interfaces into separate hierarchies within each
  project, where each top-level directory under the zope package
  is a separate project.

- Moved everything to src from lib/python.

  lib/python will eventually go away. I need access to the cvs
  repository to make this happen, however.

There are probably some bits that are broken. All tests pass
and zope runs, but I haven't tried everything. There are a number
of cleanups I'll work on tomorrow.

it goes to the start of the new log file.

self._tbuf was unexpectedly None.  The only way this can happen is
when the storage is closed (probably by a different thread); close()
sets _tbuf to None.  It turns out that a TransactionBuffer instance
can safely be closed more than once, so there's no need to set _tbuf
to None in the close() method.

recent confusion would have been avoided had the instructions been
followed.

I am glad to make this commit that fixes up a lot of the FTP
implementation. I fixed the behavior of many of the FTP commands,
including LIST, SIZE, and CWD.

I moved the original VFSFile/DirectoryView into abstract classes and wrote
a special implementation for each content type, which makes the code much
more flexible.

Also I finally implemented a smart way of adding files via VFS through
file extension introspection, based on Jim's ExtensionViewName proposal.

I am adding documentation in the DevelCookbook right now and will later
add a README file.

TODOs:

- make VFS View names flexible, so that file extensions specify views.

- Simplify ZCML directives, so that one can add new extensions for Add views
  quicker. A solution might look like that:

      <vfs:view
          name=".dtml"
          for="Zope.App.OFS.Container.IAdding."
          factory=".DTMLPageAdd."
          permission="Zope.ManageContent">
        <vfs:extension name=".html" />
        <vfs:extension name=".xul" />
        <vfs:extension name=".xml" />
        ...
      </vfs:view>

  This method would also be good for defining a default fiel extension.

- Show an object with its default file extension.

bsddb3Storage becomes BDBStorage
Full becomes BDBFullStorage
Minimal becomes BDBMinimalStorage

- start_zeo_server():  Only quote the command line args for Windows;
  these break the tests on Linux, which would only need the quoting if
  the shell were involved: it's not for os.spawnve().

Merge to HEAD: The ZEO unit tests and wo_pcgi.py didn't run on Windows if the path to the python executable included a space.

to a previously created storage.

Starts near the end of the file and reads forward, looking for a
complete snapshot.  If it doesn't find one, move farther from the end
and repeat.

XXX This approach does N**2 reads, where N is the number of times we
need to move further back and retry.  When we move backwards, we
double the distance from the end of the file.
