Zope-like transaction manager via WSGI middleware

Project Description
repoze.tm2 (Transaction Manager)
===============================

Middleware which uses the ZODB transaction manager to wrap a call to
its pipeline children inside a transaction. This is a fork of the
``repoze.tm`` package which depends only on the ``transaction``
package rather than the entirety of ZODB (for users who don't rely on ZODB).

See docs/index.rst for documentation.


1.0a4 (2009/1/6)
================

- RESTify CHANGES, move docs in README.txt into Sphinx.

- Remove ``setup.cfg`` (all dependencies available via PyPI).

- Synchronization point with ``repoze.tm`` (0.9).

1.0a3
=====

Allow ``commit_veto`` hook to be specified within Paste config, ala::

[filter:tm]
use = repoze.tm:make_tm
commit_veto = some.package:myfunction

``myfunction`` should take three args: environ, status, headers and
should return True if the txn should be aborted, False if it should be
committed.

Initial PyPI release.

1.0a2 (2008/7/15)
=================

- Provide "commit_veto" hook point (contributed by Alberto Valverde).

- Point easy_install at http://dist.repoze.org/tm2/dev/simple via setup.cfg.

1.0a1
=====

- Fork point: we've created repoze.tm2, which is repoze.tm that has a
dependency only on the 'transaction' package instead of all of ZODB.

- Better documentation for non-Zope usage in README.txt.

0.8
===

- Relaxed requirement for ZODB 3.7.2, since we might need to use the
package with other verions. Note that the tests which depend on
transaction having "doom" semantics don't work with 3.7.2, anyway.

0.7
===

- Depend on PyPI release of ZODB 3.7.2. Upgrade to this by doing
bin/easy_install -U 'ZODB3 >= 3.7.1, < 3.8.0a' if necessary.

0.6
===

- after_end.register and after_end.unregister must now be passed a
transaction object rather than a WSGI environment to avoid the
possibility that the WSGI environment used by a child participating
in transaction management won't be the same one used by the
repoze.tm package.

- repoze.tm now inserts a key into the WSGI environment
(``repoze.tm.active``) if it's active in the WSGI pipeline. An API
function, repoze.tm:isActive can be called with a single argument,
the WSGI environment, to check if the middleware is active.

0.5
===

- Depend on rerolled ZODB 3.7.1 instead of zopelib.

- Add license and copyright, change trove classifiers.

0.4
===

- Depend on zopelib rather than ZODB 3.8.0b3 distribution, because the
ZODB distribution pulls in various packages (zope.interface and ZEO
most notably) that are incompatible with stock Zope 2.10.4 apps and
older sandboxes. We'll need to revisit this.

0.3
===

- Provide limited compatibility for older transaction package versions
which don't support the 'transaction.isDoomed' API.

0.2
===

- Provide after_end API for registering callbacks at transaction end.

0.1
===

- Initial Release
