Jython NEWS

The features new in a given version are listed at the head of the section for

the final release of that version. Bugs fixed are listed under the next release

(frequently a beta) after they were fixed.

For more details, three sources are available according to type:

- [ n ], please see old bug tracker at https://bugs.jython.org.

- [ GH-n ], please see https://github.com/jython/jython.

- [ FM-n ], please see https://github.com/jython/frozen-mirror.

==============================================================================

Jython 2.7.5

==============================================================================

New Features

- Servlet support is updated to use the jakarta namespace. As part of this

change, the classes org.python.util.PyServlet, org.python.util.PyFilter

and org.python.util.PyServletInitializer have been relocated to a new

package org.python.servlet. Users should double-check that this change is

adjusted in their config if necessary.

The relocation allows adding the old classes (with javax.servlet imports)

to the classpath on top of jython.jar without name conflict. In many cases

this should suffice to retain workability of a legacy setup if needed.

- Upgrade of jffi to 1.3.14 eliminates the need for sun.misc.Unsafe, which is

deprecated for removal in Java 26. See https://github.com/jnr/jffi/issues/165

Jython 2.7.5a1 Bugs fixed

- [ GH-382 ] Java EE Servlet namespace changed from javax.servlet to jakarta.servlet

- [ GH-356 ] _ast.astlist.__add__ leads to Java exception

- [ GH-84 ] PyServlet will need to use the jakarta.servlet namespace

==============================================================================

Jython 2.7.4

==============================================================================

New Features

- When building a modular application or library, the jython-slim JAR may

be placed on the *module* path [GH-325]. It will export its usual

packages in an automatic module org.python.jython2. Application build

tools that create a run script will generally add the dependencies of

Jython to the module path automatically. The developer may have to add

(via the build script) --add-modules ALL-MODULE-PATH to the java command

to ensure that these dependencies are resolved.

- The jython-standalone JAR (module org.python.jython2.standalone) may

also be used. Many shaded (and some unshaded) dependencies are then

duplicated in its module, which can be a problem. It may be necessary to

--add-modules ALL-DEFAULT to ensure JDK classes are resolved.

==============================================================================

Jython 2.7.3

==============================================================================

New Features

- The jython command respects the PYTHONDONTWRITEBYTECODE environment

variable (GH-128).

- Under PR GH-101, the matching of sequence arguments to the parameters of

Java methods is improved (and in constructors under GH-201). A Java

varargs parameter does not match a final sequence in the call if an array

parameter could do so. (Thanks Peter Holloway.)

- array.array itemsize of unsigned types is now the same as their signed

counterparts, where previously it was mostly double. Internal

representations have changed. Anomalies have been eliminated between

itemsize and the serialisation (tostring() etc.) for unsigned types, and

in the range of values accepted in different contexts. The size of type

'u' (unicode character) is 4 on all platforms. Client code that was

working around these anomalies may have to change. Overall, the

experience should be closer to that with CPython.

- We no longer aspire to compile Jython with Java 7. (We may use Java 8

features.)

- The project has moved its home to GitHub (twice), and invites issue

reports there (not at bugs.jython.org).

==============================================================================

Jython 2.7.2

==============================================================================

New Features

- The main program behaves more like CPython in many small ways, including

a more correct treatment of the -i option. This simplifies support, and

may also make it unnecessary for users to work around differences from

CPython.

- python.startup registry property (and JYTHONSTARTUP environment variable)

added.

- Only the Jython command (class org.python.util.jython) now reads the

environment variable JYTHONPATH, not the core runtime, and it respects

the -E option (ignore environment). This change is for consistency with

CPython and with our handling of other environment variables. A pure Java

application that creates its own interpreter may use the system or

registry key "python.path" to add to sys.path, as documented.

- We no longer recommend overriding toString in PyObject sub-classes as a

way of defining string forms. Override __repr__, and if necessary __str__,

as is usual in Python. We recommend toString should return the same as

__str__ (or __unicode__).

- Experimentally, we use Gradle to build a JAR and POM that may be cited as

a dependency by other projects. The Jython project would like to know if

this is being done suitably for downstream use.

- The registry setting (or Java property) "python.verbose", and direct use

of the global org.python.core.Options.verbose are DEPRECATED: use a Java

logging properties file instead. Console messages are now produced via

java.util.logging (JUL), and the logger "org.python" or its descendants.

The jython command configures a ConsoleLogger for "org.python" and by

default a format for messages generally similar to that in v2.7.1,

preceded by the logger name and JUL severity. The volume of messages is

controlled by your logging preferences, but by default is unchanged from

v2.7.1. Each -v option on the command line makes the logging one step

finer on the JUL scale. Error messages from Python and stack traces are

unaffected. When embedded in your application, Jython makes no logging

configuration changes: messages from the "org.python" name space merge

with those of your application.

- There is much improved support for locale, but as a backward-incompatible

change, it is provided as an opt-in. Define property

python.locale.control=settable on the command line or via the Jython

registry, to enable. This may become the default in a later version.

- The default location of the Jython package cache has moved from the

installation directory to the current working directory and is called

".jython_cache". Previously, Jython installed system-wide either exposed

the cache as world read-write (a security risk) or disabled it.

- BouncyCastle SSL support is incomplete as bundled. The Jython JAR is not

signed, and may not be trusted by your JVM as a security provider. This

manifests as a PEMException: "Unable to create OpenSSL PBDKF:

PBKDF-OpenSSL SecretKeyFactory not available" during certain operations.

If this is a problem, place genuine BouncyCastle JARs on the class path,

and Jython will use those in preference to the classes we include.

The slim JAR does not suffer this problem.

New Features

- Updated Netty to 4.1.11, ASM to 5.2, BouncyCastle to 1.57, Commons Compress to 1.14,

Guava to 22.0, ICU4J to 59.1, JFFI to 1.2.15, JNR-JFFI to 2.1.5, JNR-POSIX to 3.0.41,

JNR-Constants 0.9.9, JLine to 2.14.3, MySQL Connector to 5.1.42, PostgreSQL to 42.1.1

Note:

You might find it strange that Jython bundles guava-22.0-android.jar rather than guava-22.0.jar.

This is the official way to support Java 7 with Guava > 20.0, also on non-Android platforms.

See https://github.com/google/guava/wiki/Release22#guava-release-220-release-notes.

- There is now support for non-ascii paths in all (home, installation, temporary)

directories, which previously caused failures. sys.getplatformencoding() returns

'utf-8' as the nominal file-system encoding, irrespective of localization. This may

differ from what CPython reports on the same OS. In Jython a file path presented

as bytes is the UTF-8 encoding of the unicode file path as Java sees it. (See issues

#1839 and #2356.) This matter is unrelated to file.encoding or the console.

New Features

- Recognize cpython_cmd property to automatically build CPython bytecode for oversized

functions (e.g. jython -J-Dcpython_cmd=python). This is especially convenient when

installing things like SymPy via pip; it would frequently prompt you to provide yet

another pyc-file. Now just run: pip install --global-option="-J-Dcpython_cmd=python" sympy

- SymPy is now workable. (However it runs somewhat slow; some profiling will be required.)

- Updated ucnhash to support name lookup for Unicode 9.0 (like in u'\N{name}').

- Jython doc-entries in Java-code (__doc__foo) now accept anything that implements

java.lang.CharSequence (PyString implements CharSequence now as well).

This allows Jython-friendly Java-code without PyString-induced dependency on Jython.

- Provided a painless way to deal with long-standing Issue 527524 - "Cannot compile to use

methods exceeding JVM size restrictions": If a CPython 2.7 bytecode-file (.pyc) exists,

Jython automatically uses that bytecode to represent oversized functions and methods,

while methods with proper size are still compiled to JVM bytecode.

The crucial bytecode sections from the pyc-file are embedded seamlessly into the created

class-file, so you wouldn't have to distribute the pyc-file at all.

Current implementation of this feature is provisional and might change in future versions.

Issue 527524 was still not listed as solved, because Jython cannot yet create the pyc-file

by itself.

- Support for CPython bytecode (.pyc-files) was updated to Python 2.7 bytecode (from 2.5).

- Buffer API changes allow java.nio.ByteBuffer to provide the storage when a PyBuffer

is exported. This is to support CPython extensions via JyNI, but has other uses too

(including access to direct memory buffers from Python). There is no change at the

Python level or for client code using PyBuffer via the "fully encapsulated" API. It

risks breaking code that makes direct access to a byte array via PyBuffer, implements

the PyBuffer interface, or extends implementation classes in org.python.core.buffer.

- Updated Netty to 4.1.4

- Fixed platform.mac_ver to provide actual info on Mac OS similar to CPython behavior.

- Added uname function to posix module. The mostly Java-based implementation even

works to some extend on non-posix systems (e.g. Windows).

Jython 2.7rc2

Bugs fixed

- [ 2301 ] time.strftime now always returns a bytestring (fixes pip on Japanese locales)

- [ 2297 ] Updates Jython installer to use jython.exe

- [ 2298 ] Fix setuptools wheel bundled by ensurepip so it checks for Windows on Jython

- [ 2300 ] Fix bin/jython.py to not consume subcommand args

New features

- Installer installs pip, setuptools by default, but custom builds can de-select.

Does not change standalone usage. (Runs jython -m ensurepip as last install step.)

- Makes jython.py be the default launcher (as bin/jython) if CPython 2.7 is available.

Removed support

- Installer no longer supports using an alternative JRE when generating Jython launchers.

Instead just use JAVA_HOME environment variable to select the desired JRE.

(Removed because of the new native launcher, jython.exe, that is now used on Windows.)

Jython 2.7rc1

Bugs fixed

- [ 1793 ] Fix relative seek in read/write mode via a non-buffered readinto() method

- [ 2282 ] Speed up startup with compiled $py.class files included for standalone, full jars

- [ 1371, 2283, 2296 ] More robustness wrt security managers, python.home, import of non-ascii names

- [ 1491 ] Windows launcher now uses jython.exe (built with PyInstaller) instead of jython.bat

This means that pip, nosetests, yolk, and other installed tool scripts finally work on Windows

New features

- Can add a __dict__ slot descriptor to a subclass of Java classes, such as java.util.HashMap

- Directly execute zip files or dirs with top level __main__.py to support wrapper scripts

generated by distlib, part of pip

- Reflection-based traversal is now activated by default as a fallback for ordinary traversal.

This impacts third-party extenders of PyObject. A warning is emitted that suggests next steps

on how to avoid this cost.

- Uses classpath wildcard in jython.py/jython.exe to minimize the launcher command line,

(main benefit is Jython developers on Windows using dev builds)

- Adds new Jython launcher written in Python, bin/jython.py, to be run by CPython 2.7

(i.e. attributes bound to a PyObject via a WeakHashMap) in an analogue way (See JyAttribute.java).

New features

- Full support of Python buffer protocol, along with Java ByteBuffer support

- Add index to PyUnicode facilitating O(1) access to strings beyond the BMP.

- java.util.{Map, List, Set} are now treated as subclasses of the

corresponding Python abstract base classes

- jythonlib module to simplify usage of Java internals from Python;

weakref collections now directly use corresponding collections from

Google Guava and java.util

- CPython's _json.c was ported to Java to speed up JSON encoding/decoding

- Upgraded third party libraries

- Initial support for ensurepip module

- Callbacks can be registered/unregistered to be notified when

bytecode is loaded, using jythonlib.bytecodetools

- Jython now features an optional, but recommended-to-implement traverseproc-mechanism

like CPython. This enables some new gc-features to optionally emulate CPython-specific

gc-behavior. See doc in gc.java and Traverseproc.java.

Potentially backwards breaking changes, removing silent errors:

- remove method on proxied List objects now follows Python

semantics: a ValueError is raised if the item is not found in the

java.util.List. In the past, Java semantics were used, with a

boolean returned indicating if the item was removed or

not. Given how this interacted with Jython, such remove

invocations were in the past silent, and perhaps were actually a

bug.

- d[key_not_present], if d implement java.util.Map, no longer

returns None, but raises KeyError, which means this behavior now

matches standard dict semantics.

- Abstract methods of an inherited class or interface from Java now raise

NotImplementedError, instead of returning None (in Java, null) or some

"zero", if they are not implemented in the extending Python class.

- os.getenv, os.listdir, sys.argv now return unicode instead of

str values if a given value is not ascii, thus allowing such

values to be passed through to Java, eg

java.io.File(sys.argv[1]). Earlier such behavior was potentially

silently failing in Python functions, but passing through to

Java because of bug 2037. This behavior conforms with Python

3.x, which uses Unicode.
