Jython NEWS
The features new in a given release are generally listed under the section for the "b1" release
of that version.
For more details, three sources are available according to type:
- [ n ], please see https://hg.python.org/jython.
- [ GH-n ], please see https://github.com/jython/jython.
- [ FM-n ], please see https://github.com/jython/frozen-mirror.
Jython 2.7.3a1
Bugs fixed
- [ GH-138 ] Upgrade Guava to 31.0.1 (CVE-2020-8908)
- [ GH-139 ] Make gradlew executable on Unix/Mac
- [ GH-119 ] array.array itemsize and serialisation anomalies for unsigned types
- [ GH-122 ] Upgrade Apache commons-compress to 1.21
- [ GH-57 ] JavaWebStart compatibility broken

- [ GH-2 ] Transfer closed-fixed issues in NEWS from frozen-mirror
New Features
- 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).

- [ 2715 ] Restrict array.array support for buffer protocol
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 is not affected.

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

- Fix reflection-based garbage collection traversal for CPython compatible gc semantics
- [ 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

- [ 2224 ] id(...) now persists object resurrection and a pattern is provided to solve similar issues
(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
sematics: 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.
Jython 2.7b3
