:alt: Documentation Status
Venusian is a library which allows framework authors to defer
decorator actions. Instead of taking actions when a function (or
class) decorator is executed at import time, you can defer the action
usually taken by the decorator until a separate "scan" phase.
See the "docs" directory of the package or the online documentation at
https://docs.pylonsproject.org/projects/venusian/en/latest/
3.0.0 (2019-10-04)
------------------
- This release matches 2.0.0 other than in the version number. This fixes an
issue with Requires-Python metadata not being uploaded correctly to PyPi.
This version is only compatible with Python 3.5+
2.0.0 (2019-10-04)
------------------
- Drop support for Python 2.7, 3.3, and 3.4
- Removed the usage of the ``imp`` module to squelch the warnings regarding a
deprecated modules. See https://github.com/Pylons/venusian/pull/63 and
https://github.com/Pylons/venusian/issues/57
1.2.0 (2019-01-08)
------------------
- Add support for Python 3.7.
- Drop support for Python 3.3.
1.1.0 (2017-04-24)
------------------
- Updated to using py.test instead of nosetest, and added support for Python
3.4 -> 3.6
- Make scanning more resilient of metaclasses that return proxies for any
attribute access.
- Fix bug where using the same venusian decorator on both a class and its
methods would cause the method decorations to be ignored. See
https://github.com/Pylons/venusian/issues/40
- Drop support for Python 2.6.
- Drop support for Python 3.2: it is no longer supported by current
packaging / CI tools.
- Support loaders that require the module name as argument to their
``get_filename()`` method. This fixes problems with zipped packages
on Python 3.
- Micro-optimization when ignores are used (see
https://github.com/Pylons/venusian/pull/20).
- A tox run now combines coverage between Py2 and Py3.
1.0 (2014-06-30)
----------------
- Fix an issue under PyPy > 2.0 where attached decorators may not be found.
- Drop support of Python 2.4 / 2.5 / Jython.
- Add ``lift`` and ``onlyliftedfrom`` class decorators to allow for inheritance
of venusian decorators attached to superclass methods. See the API
documentation for more information.
- Fix bug where otherwise undecorated subclass of a superclass that had
venusian decorators on it would inherit its superclass' decorations.
Venusian decorators should have never been inherited implicitly. See
https://github.com/Pylons/venusian/issues/11#issuecomment-4977352
1.0a8 (2013-04-15)
------------------
- Pass ``ignore`` argument along recursively to ``walk_packages`` so custom
ignore functions will ignore things recursively. See
https://github.com/Pylons/venusian/pull/16
- Don't run tox tests under Python 2.4 anymore (tox no longer supports 2.4).
1.0a7 (2012-08-25)
------------------
- Venusian now works on Python 3.3b2+ (importlib-based).
- Use nose-exclude instead of relying on fragile module-scope code to ensure
we don't get errors resulting from import of fixture code during
"nosetests".
- Bug fix: no longer suppress ``ImportError`` while scanning by default. If
you want to suppress ``ImportError`` while scanning, you'll now need use an
``onerror`` callback as described in the documentation.
1.0a6 (2012-04-23)
------------------
- Don't ignore decorated objects within their original locations if they
happen to be imported into another module (remove ``seen`` set from invoke
in venusian scanning). See https://github.com/Pylons/venusian/pull/13 .
1.0a5 (2012-04-21)
------------------
- Slightly less sucky way to ignore objects during scanning that are only
imported into a module but not actually defined there. See 1.0a4 change
notes for rationale. Now instead of checking whether the module of the
*scanned object* matches the module being scanned, we check whether the
module of the *Venusian attachment* matches the module being scanned. This
allows some genuine uses of imported objects as Venusian scan targets while
preventing inappropriate double-scanning of objects that have a venusian
attachment which just happen to be imported into other scanned modules.
- Add ``dev`` and ``docs`` setup.py commands (ala Pyramid).
1.0a4 (2012-04-16)
------------------
- Attempt to ignore objects during scanning that are only imported into a
module but not actually defined there. This is a semantics change, but
it's the right thing to do, because I found myself facing a situation like
this::
# in a module named "one"
from two import anotheradecoratedthing
@adecorator
def adecoratedthing(): pass
# and scanning both modules
scan('one')
scan('two')
In this case you'd wind up with two repeated registrations for
"anotherdecoratedthing", which isn't what anyone expects.
1.0a3 (2012-02-08)
------------------
- Add an ``ignore`` argument to the ``scan`` method of a ``Scanner``. This
argument allows a user to ignore packages, modules, and global objects by
name during a ``scan``. See the "ignore Scan Argument" in the narrative
documentation for more details.
1.0a2 (2011-09-02)
------------------
- Close ImpLoader file handle to avoid resource warnings on Python 3.
1.0a1 (2011-08-27)
------------------
- Python 3 compatibility.
- Allow an ``onerror`` callback to be passed to ``Scanner.scan()``.
0.9 (2011-06-18)
----------------
- Prevent corner case scan-time exception when trying to introspect insane
module-scope objects. See https://github.com/Pylons/venusian/issues/5 .
0.8 (2011-04-30)
----------------
- Normal "setup.py test" can't support running the venusian tests under py
2.4 or 2.5; when it scans the 'classdecorators' fixture, it barfs. To get
around this, we used to depend on ``nose`` in ``setup_requires`` and tell
"setup.py test" to use nose by setting test_suite to "nose.collector" but
we can't anymore because folks use Venusian in systems which install from
pip bundles; pip bundles do not support setup_requires. So, sorry, we're
painted into a corner; at this point you just have to know to install nose
and run "setup.py nosetests" rather than "setup.py test". Or just run
"tox" which tests it under all Pythons.
0.7 (2011-03-16)
----------------
- Use Pylons theme in documentation.
- Fix orphaned pyc test on pypy.
- Fix GitHub Issue #1: subclasses of decorated classes that do not
have any decorations should not inherit the decorations of their
parent classes.
- Fix GitHub Issue #2: scans should only "find" each object once per
scan, regardless of how many modules that object is imported into.
0.6 (2011-01-09)
----------------
- Some metaclasses (Elixir's) don't raise an AttributeError when asked for a
nonexistent attribute during a scan. We now catch all exceptions when
interrogating an object for ``__venusian_callbacks__`` rather than just
AttributeError.
0.5 (2010-12-19)
----------------
- Make ``codeinfo`` attribute available as an attribute of the AttachInfo
object. It will be a tuple in the form ``(filename, lineno, function,
sourceline)`` representing the context of the venusian decorator. Eg.
``('/home/chrism/projects/venusian/tests/test_advice.py', 81,
'testCallInfo', 'add_handler(foo, bar)')``
0.4 (2010-09-03)
----------------
- Bug fix: when a venusian decorator used as a class decorator was
used against both a class *and* a subclass of that class, the
superclass and subclass would effectively share the same set of
callbacks. This was not the intent: each class declaration should
have its own local set of callbacks; callbacks added via decorations
should not be inherited, and a superclass should not receive its
subclass' decorations.
- Arrange test fixtures into a single directory.
0.3 (2010-06-24)
----------------
- Ignore orphaned modules (``.pyc`` or ``.pyo`` files without a
corresponding ``.py`` file) during a scan.
0.2 (2010-04-18)
----------------
- Add the concept of scan categories (see the "Scan Categories"
section of the documentation) to allow an application to make use of
more than one Venusian-using framework simultaneously.
0.1 (2010-02-15)
----------------
- Initial release.
