| 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 stabalized, 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. | = Jython Roadmap = |
| Line 3: | Line 3: |
| 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. PEPs 292, 305, 324 and 327 should be doable with trunk as can the template removal tasks and bugtests migration at the end of the list. | |

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
- Import Python from the classpath
- Performance improvements
Future?
- Translate summer of code compiler to Java *Incorporated, except for pyc support
