2.7.1

  • Fixed invariants leak between related classes (#297)

This is a critical bugfix patch version. We introduced a bug in 2.7.0 (#292) where invariants defined on derived classes leaked up to parent classes. This bug is fixed in this version.

2.7.0

  • Allowed to enforce invariants on attribute setting (#292)

    Originally, we had enforced invariants only at calls to "normal" methods, and excluded __setattr__ since it is usually too expensive to verify invariants whenever setting an attribute.

    However, there are use cases where the users prefer to incur to computational overhead for correctness. To that end, we introduced the feature to steer when the invariants are enforced (at method calls, on setting attributes, or in both situations).

2.6.6

  • Updated typeguard and deal to latest versions (#284)

    This change is needed so that distributions can successfully run the necessary tests with the development dependencies. Previously, the dependencies were outdated, and the old versions were already deprecated in distributions (notably, typegard and deal).

2.6.5

  • Added Python 3.11 to the list of supported Pythons (#280)

  • Fixed deal dependency marker (#279)

    This patch is important as we silently broke setup.py, which was tolerated by older versions of setuptools, but not any more by the newer ones. With this patch, icontract's setup.py is made valid again.

2.6.4

  • Restored Python 3.6 support (#274)

    The support for Python 3.6 has been dropped in #257 as GitHub removed its support in the CI pipeline. With this patch, we restored the support of Python 3.6. Notably, we had to add the package contextvars conditioned on Python 3.6.

  • Refactored and added tests for integrators (#182)

2.4.0

  • Integrated with icontract-hypothesis (#179)
  • Refactored for icontract-hypothesis (#178)
  • Added special arguments _ARGS and _KWARGS (#176)

  • Added support for named expressions in contracts (#166)

2.3.7

  • Acted upon deprecation warning ins ast module when generating the violation error message.

2.3.6

  • Denormalized icontract_meta so that icontract can be installed on readthedocs.

2.3.5

  • Disabled invariant checks during the construction to avoid attribute errors on uninitialized attributes

2.3.4

  • Added icontract_meta to setup.py
  • Noted that contracts on *args and **kwargs are known issues

2.3.3

  • Fixed performance regression due to state

2.3.2

  • Fixed bug related to threading.local and mutables

2.3.1

  • Fixed race conditions in endless recursion blockers

2.3.0

  • Disabled recursion in the contracts
  • Upgraded min version of asttokens to 2

2.2.0

  • Made compatible with Python 3.8

2.1.0

  • Made snapshot accept multiple arguments

2.0.7

  • Fixed mypy complaints in clients due to import aliases

2.0.6

  • Added location to errors on calls with missing arguments

2.0.5

  • Improved error message on unexpected arguments in a call
  • Distinguished between optional and mandatory arguments in conditions. Default argument values in conditions are accepted instead of raising a misleading "missing argument" exception.
  • Added a boolyness check to detect if the condition evaluation can be negated. If the condition evaluation lacks boolyness, a more informative exception is now raised. For example, this is important for all the code operating with numpy arrays where boolyness is not given.
  • Added contract location to require, ensure and snapshot. This feature had been erroneously omitted in 2.0.4.

  • Added contract location to the message of the violation error

2.0.3

  • Fixed representation of numpy conditions
