# The change history of PyCall ## 1.5.1 * Fix memory leak in rich compare methods (#167, #168). *mknkmyza* ## 1.5.0 * Fix to prevent distutils deprecation warning (#159) *Christopher Dilks* * Drop Python 2.7 support * Fix memory leak of Python objects. (#129) This should fixes #128 and maybe also fixes #164. *mknkmyza* ## 1.4.2 * Add supports of unary operators: `+@`, `-@`, `~` * Fix `without_gvl` for exceptions occurred in the given block * Add PyCall.setattr and PyCall.delattr ## 1.4.1 * Fix SEGV occurred on Windows * Add PyCall.iterable ## 1.4.0 * Explicitly states that Windows is not supported yet in README * Add PyCall.same? * Improve conda support * Fat gem is no longer supported * Use WeakMap for caching PyPtr instances ## 1.3.1 * Stop using `&proc` idiom to prevent warnings *Kenta Murata* ## 1.3.0 * Add `PyCall.without_gvl` for explicitly releasing the RubyVM GVL * Fix for missing if in PyObjectWrapper *Kouhei Sutou* * Fix for Anaconda environment *Ryo MATSUMIYA* * Fix against `unknown symbol "PyInt_AsSsize_t"` (Fiddle::DLError) *Kouhei Sutou* * Fix for `TypeError: Compared with non class/module` *Archonic* ## 1.2.1 * Prevent circular require in pycall/iruby.rb ## 1.2.0 * Add `PyCall::Tuple#to_ary` *Naoto Takai* * Release GVL while the Python interpreter is running * Drop support Ruby 2.2.x and 2.1.x * Release GVL while the Python interpreter is running [Fix #45] * Add public header file * Use PyPtr.none? instead of removed PyCall.none? *Kouhei Sutou* * Export PyObject convert functions *Kouhei Sutou* * Support multiple candidates of Python command in `PyCall.init` * Now, `PyCall.init` tries `python3` command before `python` in default * Drop Ruby 2.2 and 2.1 supports * Add `PyCall::PyTypeObjectWrapper#<` as `Class#<` * Support class inheritance in python type mapping ## 1.0.3 * Fix anaconda support to define the environment variable `PYTHONHOME`. https://github.com/mrkn/pycall.rb/issues/37 ## 1.0.2 * Fix the bug that a large Python string is broken when it converted to Ruby string https://github.com/mrkn/pycall.rb/issues/32 ## 1.0.1 * Add PyTypeObject#===. ## 1.0.0 * `#[]` and `#[]=` accept a `Range` and an `Enumerable`, which is genated by `Range#step`, as a slice. * Rewrite almost all fundamental parts of PyCall as C extension. * PyCall now calls `Py_DecRef` in the finalizer of `PyCall::PyPtr`. * Change the system of object mapping between Python and Ruby, drastically. Now PyCall does not have `PyObject` class for wrapper objects. Instead, PyCall generally makes `Object` instances and extends them by `PyObjectWrapper` module. But for Python module objects, PyCall makes anonymous `Module` instances that are extended by `PyObjectWrapper` module. Moreover for Python type objects, PyCall makes `Class` instances and extends them by `PyTypeObjectWrapper` module. * Change `PyCall.eval` to be a wrapper of `__builtins__.eval` in Python. This means that `filename:` and `input_type:` parameters are dropped. Instead, two new parameters `globals:` and `locals:` are introduced. `globals:` is used for specifying a dictionary that is the global namespace referred by the evaluated expression. `locals:` is used for specifying a mapping object that is the local namespace referred by the evaluated expression. * Add `PyCall.exec` for the replacement of the former `PyCall.eval` with `input_type: :file`. It has `globals:` and `locals:` parameters for the same meaning as the new `PyCall.eval` described above. * Drop `PyCall.wrap_ruby_callable` and `PyCall.wrap_ruby_object` always craetes a callable Python object taht has an ID of the given Ruby object.
