Changelog

This changelog only contains changes from the first pypi release (0.5.4.3) onwards.

• Next version - unreleased

• 0.7.1 - 12-16-2019

  • Updated the keyword safe list for Python 3.

  • Automatic conversion of CharSequence from Python strings.

  • java.lang.AutoCloseable supports Python “with” statement.

  • Hash codes for boxed types work properly in Python 3 and can be used as dictionary keys again (same as JPype 0.6). Java arrays have working hash codes, but as they are mutable should not be used as dictionary keys. java.lang.Character, java.lang.Float, and java.lang.Double all work as dictionary keys, but due to differences in the hashing algorithm do not index to the same location as Python native types and thus may cause issues when used as dictionary keys.

  • Updated getJVMVersion to work with JDK 9+.

  • Added support for pickling of Java objects using optional module jpype.pickle

  • Fixed incorrect string conversion on exceptions. str() was incorrectly returning getMessage rather than toString.

  • Fixed an issue with JDK 12 regarding calling methods with reflection.

  • Removed limitations having to do with CallerSensitive methods. Methods affected are listed in caller-sensitive. Caller sensitive methods now receive an internal JPype class as the desut

  • Fixed segfault when converting null elements while accessing a slice from a Java object array.

  • PyJPMethod now supports the FunctionType API.

  • Tab completion with Jedi is supported. Jedi is the engine behind tab completion in many popular editors and shells such as IPython. Jedi version 0.14.1 is required for tab completion as earlier versions did not support annotations on compiled classes. Tab completion with older versions requires use of the IPython greedy method.

  • JProxy objects now are returned from Java as the Python objects that originate from. Older style proxy classes return the inst or dict. New style return the proxy class instance. Thus proxy classes can be stored on generic Java containers and retrieved as Python objects.

• 0.7.0 - 2019

  • Doc strings are generated for classes and methods.

  • Complete rewrite of the core module code to deal unattached threads, improved hardening, and member management. Massive number of internal bugs were identified during the rewrite and corrected. See the JPype 0.7 Core ChangeLog for details of all changes.

  • API breakage:

    • Java strings conversion behavior has changed. The previous behavior was switchable, but only the default convert to Python was working. Converting to automatically lead to problems in which is was impossible to work with classes like StringBuilder in Java. To convert a Java string use str(). Therefore, string conversion is currently selected by a switch at the start of the JVM. The default shall be False starting in JPype 0.8. New code is encouraged to use the future default of False. For the transition period the default will be True with a warning if not policy was selected to encourage developers to pick the string conversion policy that best applies to their application.

    • Java exceptions are now derived from Python exception. The old wrapper types have been removed. Catch the exception with the actual Java exception type rather than JException.

    • Undocumented exceptions issued from within JPype have been mapped to the corresponding Python exception types such as TypeError and ValueError appropriately. Code catching exceptions from previous versions should be checked to make sure all exception paths are being handled.

    • Undocumented property import of Java bean pattern get/set accessors was removed as the default. It is available with import jpype.beans, but its use is discouraged.

  • API rework:

    • JPype factory methods now act as base classes for dynamic class trees.

    • Static fields and methods are now available in object instances.

    • Inner classes are now imported with the parent class.

    • jpype.imports works with Python 2.7.

    • Proxies and customizers now use decorators rather than exposing internal classes. Existing JProxy code still works.

    • Decorator style proxies use @JImplements and @JOverload to create proxies from regular classes.

    • Decorator style customizers use @JImplementionFor

    • Module jpype.types was introduced containing only the Java type wrappers. Use from jpype.types import * to pull in this subset of JPype.

  • synchronized using the Python with statement now works for locking of Java objects.

  • Previous bug in initialization of arrays from list has been corrected.

  • Added extra verbiage to the to the raised exception when an overloaded method could not be matched. It now prints a list of all possible method signatures.

  • The following is now DEPRECATED

    • jpype.reflect.* - All class information is available with .class_

    • Unncessary JException from string now issues a warning.

  • The followind is now REMOVED

    • Python thread option for JPypeReferenceQueue. References are always handled with with the Java cleanup routine. The undocumented setUsePythonThreadForDaemon() has been removed.

    • Undocumented switch to change strings from automatic to manual conversion has been removed.

    • Artifical base classes JavaClass and JavaObject have been removed.

    • Undocumented old style customizers have been removed.

    • Many internal jpype symbols have been removed from the namespace to prevent leakage of symbols on imports.

  • promoted `–install-option` to a `–global-option` as it applies to the build as well as install.

  • Added `–enable-tracing` to setup.py to allow for compiling with tracing for debugging.

  • Ant is required to build jpype from source, use --ant= with setup.py to direct to a specific ant.

• 0.6.3 - 2018-04-03

  • Java reference counting has been converted to use JNI PushLocalFrame/PopLocalFrame. Several resource leaks were removed.

  • java.lang.Class<>.forName() will now return the java.lang.Class. Work arounds for requiring the class loader are no longer needed. Customizers now support customization of static members.

  • Support of java.lang.Class<>

    • java.lang.Object().getClass() on Java objects returns a java.lang.Class rather than the Python class

    • java.lang.Object().__class__ on Java objects returns the python class as do all python objects

    • java.lang.Object.class_ maps to the java statement java.lang.Object.class and returns the java.lang.Class<java.lang.Object>

    • java.lang.Class supports reflection methods

    • private fields and methods can be accessed via reflection

    • annotations are avaiable via reflection

  • Java objects and arrays will not accept setattr unless the attribute corresponds to a java method or field whith the exception of private attributes that begin with underscore.

  • Added support for automatic conversion of boxed types.

    • Boxed types automatically convert to python primitives.

    • Boxed types automatically convert to java primitives when resolving functions.

    • Functions taking boxed or primitives still resolve based on closest match.

  • Python integer primitives will implicitly match java float and double as per Java specification.

  • Added support for try with resources for java.lang.Closeable. Use python “with MyJavaResource() as resource:” statement to automatically close a resource at the end of a block.

• 0.6.2 - 2017-01-13

  • Fix JVM location for OSX.

  • Fix a method overload bug.
