repoze.tm2 2.2.0

Description:

repoze.tm2 2.2.0

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).

Installation
Install using setuptools, e.g. (within a virtualenv):
$ easy_install repoze.tm2
or using pip:
$ pip install repoze.tm2


Usage
For details on using the various components, please see the
documentation in docs/index.rst. A rendered version of that documentation
is also available online:

Changelog

2.2.0 (2023-01-16)

Add support for Python 3.7, 3.8, 3.9, 3.10, and 3.11.
Drop suppport for Python 2.7, 3.4, 3.5 and 3.6.
Add Github Actions workflow running unit tests / coverage for PRs.



2.1 (2016-06-03)

Add support for Python 3.4, 3.5 and PyPy3.
Drop support for Python 2.6 and 3.2.
Add support for testing under Travis.



2.0 (2013-06-26)

Avoid swallowing the original exception while aborting the transaction
in middleware. See PR #3.



2.0b1 (2013-04-05)

Middleware is now a generator, to deal appropriately with application
iterators which are themselves not lists.
Convert use of deprecated failIf/failUnless to assertFalse/assertTrue.
Add support for testing under supported Pythons using Tox.
Add explicit support for Python 3.2 ad 3.3.
Drop support for Python 2.4, 2.5.



1.0 (2012-03-24)

Run OOTB under Python 2.4 / 2.5 (pin ‘transaction’ dependency to
a supported version when running under 2.4 / 2.5).



1.0b2 (2011-07-18)

A new header X-Tm is now honored by the default_commit_veto commit
veto hook. If this header exists in the headerlist, its value must be a
string. If its value is commit, the transaction will be committed
regardless of the status code or the value of X-Tm-Abort. If the value
of the X-Tm header is abort (or any other string value except
commit), the transaction will be aborted regardless of the status code
or the value of X-Tm-Abort.
Use of the X-Tm-Abort header is now deprecated. Instead use the
X-Tm header with a value of abort instead.
Add API docs section.



1.0b1 (2011-01-19)

Added repoze.tm.default_commit_veto commit veto hook. This commit veto
hook aborts for 4XX and 5XX response codes, or if there’s a header named
X-Tm-Abort in the headerlist and allows a commit otherwise.
Documented commit veto hook.



1.0a5 (2009-09-07)

Don’t commit after aborting if the transaction was doomed or if the
commit veto aborted.
Don’t use “real” transaction module in tests.
100% test coverage.



1.0a4 (2009-01-06)

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 (2008-08-03)
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 (2008-07-15)

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 (2008-01-09)

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 (2007-10-11)

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 (2007-09-25)

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 (2007-09-21)


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 (2007-09-18)

Depend on rerolled ZODB 3.7.1 instead of zopelib.
Add license and copyright, change trove classifiers.



0.4 (2007-09-17)

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 (2007-09-14)

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



0.2 (2007-09-13)

Provide after_end API for registering callbacks at transaction end.



0.1 (2007-09-10)

Initial Release
