Jython Roadmap

Position Now

(Least edited February 2013.)

v2.5.3 is current.

Current Plan

(Least edited February 2013: Needs more detail.)

v2.5.x versions may appear consolidating bug-fixes
v2.6 is skipped
v2.7 is the main focus of current work. A beta is imminent (February 2013).
v3.x (3.3 probably) is under consideration.

Who is doing what?

Bug fixes: anyone

Towards v2.7

math module: Oti
documentation, text_xrange.py, test_complex.py: Josh
grammar cleanup, test_class.py: Frank
itertools, collections: Jim
mercurial move, abcs, exceptions, posix/ntpath, io, tarfile: pjenvey
bytearray, buffer API and a partial memoryview: Jeff

Towards v3.3

Use of Java 7 invokedynamic: Jim?

Scraps of former plans

When the page bore a roadmap was for v2.6, this material was in it. Some of it is still accurate for v2.7, some is probably complete now, and some is no longer relevant. Those who know which is which are able to improve the roadmap!

2.6.0

Upgrade to Python 2.6 language and builtins, along with a substantial subset of the stdlib
Redesign PySystemState, ThreadState API
Mark true-public APIs with a suitable annotation; deprecate and/or remove obsolete APIs
Remove all user-visible singletons in org.python.core, especially any static public fields (like those in PySystemState)
Performance!
Require minimum Java 6, rip out Java 5 compatibility:
- Generic.newSetFromMap
- Believe we can remove the xercesImpl jar, livetribe-jsr223-2.0.5.jar
- can start utilizing jsr199 (the Java compiler API) for certain things (mostly for unittests I believe)
- Other things..

2.6.? (TBD)

unicodedata
cjkcodecs: yyamano
bz2 module
ReplaceJythonc
MigrateBugtests
Import Python from the classpath
Performance improvements

Future?

ctypes module
Translate summer of code compiler to Java *Incorporated, except for pyc support

 Line 1:
-This is a specific list of the features needed to make releases towards Jython 2.5.  The first alpha will be made once Jython supports all CPython 2.5 language level features.      After the alphas have stabilized, all the library and Jython-only features will be completed in the beta series of releases.  Once all the features are present in the betas, we'll go into release candidate mode until 2.5 is finally released.

Just because a feature is in the beta list, that doesn't mean it can't land before the alpha release.  It only means it isn't necessary before the alpha.  Actually since all of the alpha features are dependent on the new compiler and parser, the beta tasks can be a good starting point.
