[Jython-users] How to recover from https://github.com/jython/jython/issues/93

[Juniarti S. <jun...@ya...>]

Hi,
When I use jython2.7.2 I am hitting issue #93 <https://github.com/jython/jython/issues/93>.
I thought the fix is in jython2.7.3 but even after I am using jython2.7.3 the file permission behavior remains.

Is there anything else need to be done to have the file permission working as before jython2.7.2?

Here is how to demonstrate the regression issue in jython:
Using jython271
Jython 2.7.1 (default:0df7adb1b397, Jun 30 2017, 19:02:43)
[OpenJDK 64-Bit Server VM (Red Hat, Inc.)] on java1.8.0_372
Type "help", "copyright", "credits" or "license" for more information.
">>> import copy"

Checking the permission of the newly compile script:
[root@juniredhat1 Lib]# ls -la copy*
-rw-r--r-- 1 root root 28015 Jun 2 09:45 'copy$py.class' ===> NOTED THE FILE PERMISSION THE SAME AS THE SOURCE
-rw-r--r-- 1 root root 27996 Jun 30 2017 'copy$py.class.org'
-rw-r--r-- 1 root root 11519 Jun 30 2017 copy.py
-rw-r--r-- 1 root root 13490 Jun 2 09:45 'copy_reg$py.class'
-rw-r--r-- 1 root root 6800 Jun 30 2017 copy_reg.py

=========================================================================
Using jython273
Jython 2.7.3 (tags/v2.7.3:5f29801fe, Sep 10 2022, 18:52:49)
[OpenJDK 64-Bit Server VM (Red Hat, Inc.)] on java1.8.0_372
Type "help", "copyright", "credits" or "license" for more information.
">>> import copy"

Checking the permission of the newly compile script:
-rw------- 1 root root 26875 Jun 2 09:48 'copy$py.class' ===> NOTED THE FILE PERMISSION GOT CHANGE AS ISSUE #93 <https://github.com/jython/jython/issues/93>
-rw-r--r-- 1 root root 26856 Sep 10 2022 'copy$py.class.org'
-rw-r--r-- 1 root root 11519 Sep 10 2022 copy.py
-rw-r--r-- 1 root root 12955 Sep 10 2022 'copy_reg$py.class'
-rw-r--r-- 1 root root 6800 Sep 10 2022 copy_reg.py

I opened GitHub issue https://github.com/jython/jython/issues/246 but no one has looked at it.

I am hoping, I will get quicker respond from posting it too. 

Can someone please help on this regression issue as it is breaking our customers?
Thank you,
Juni.

My (2¢) concern would be for newer features in Java like modules and, 
more recently, Virtual Threads and things of that nature.

[Anamitra B. <abh...@us...>]

thanks a lot for all the great info - we will do an end to end test with Jython soon on java 17 - based on our use cases. Will post the results when we get there.

Jython 2 is built with Java 8 and tested with Java 8 and Java 11.

The backwards compatibility of Java versions is very high. The byte code is stable. What varies slightly is the Java API, where methods may have been removed, or others overloaded in ways that affect exactly which is found during a call.

I ran the regression tests on an installed 2.7.3 with Java 17. The expected result is explained here:

https://jython-devguide.readthedocs.io/en/latest/release_jy.html#installation-regrtest<https://jython-devguide.readthedocs.io/en/latest/release_jy.html#installation-regrtest>

With Java 17 I got an additional failure from test_httplib that is to do with header data not expected by the test. That may well be satisfactory for your application. You'll do your own tests, of course, and can repeat ours fairly easily.

There may be a 2.7.4 this year, and it may be tested with Java 17, but an eventual Jython 3 will get most of the time.

Hi

just wondering if jython 273 supports java 17? From the jython.org<http://jython.org> website - its java 8 and java 11 - does not mention java 17. If not - is there a version of jython that is coming up that will support java 17?

Re: [Jython-users] Java 17 and support for jython

[Jeff A. <ja...@fa...>]

Jython 2 is built with Java 8 and tested with Java 8 and Java 11.

The backwards compatibility of Java versions is very high. The byte code 
is stable. What varies slightly is the Java API, where methods may have 
been removed, or others overloaded in ways that affect exactly which is 
found during a call.

I ran the regression tests on an installed 2.7.3 with Java 17. The 
expected result is explained here:

https://jython-devguide.readthedocs.io/en/latest/release_jy.html#installation-regrtest

With Java 17 I got an additional failure from test_httplib that is to do 
with header data not expected by the test. That may well be satisfactory 
for your application. You'll do your own tests, of course, and can

[Jython-users] [Jython-dev] Jython 2.7.3 Released

[Jeff A. <ja...@fa...>]

The Jython Project is pleased to announce the general availability of 
Jython 2.7.3 at Sonatype. (https://search.maven.org/search?q=g:org.python)

This is a maintenance release that incorporates a number of bug-fixes, 
some kindly offered as PRs by users. It is identical to the recent 
release candidate (rc1) of about 2 weeks ago. Please report problems on 
the issue tracker (https://github.com/jython/jython/issues).

We are no longer inviting bugs at bugs.jython.org, which in due course 
will become read-only (as its python.org equivalent did this year). Bugs 
on the old tracker, whilst not entirely ignored, will not be migrated en 
masse to GitHub: if you care about one particularly, it would help us if 
you could raise it on GitHub, with a link to the b.j.o. entry.

Re: [Jython-users] Jython 2.7.3b1 Released

[Jeff A. <ja...@fa...>]

Further to the off-repo experimental work (VSJ) Jim references, as I 
became reasonably sure of the implementation approach, I migrated code 
to the "main" (not "master") branch of the Jython repo,. We will make 
"main" the default when Jython 3 is viable (agreed on jython-dev).

See https://github.com/jython/jython/tree/main

Where possible, the migration is a graft into prior work moved from 
Jython 2. For this reason, a lot of Jython 2 code waits unchanged on 
this branch in ~/src, but this folder is not referenced in the build. 
(~/core is where it's at.) I'm re-using even the core built-ins, but the 
problem of "new patch, old garment" means there is not much original but 
the shape, by the end of the replacement. As Jim says, I expect to 
re-use increasingly, with change only at the detailed level.

I took a break to release 2.7.3, so as to honour the contributions 
people had made since 2.7.2,. I hope the beta is nearly adequate, so I 
can work mostly on VSJ and 3.8.

Jeff,

This is really awesome news! Glad for the hard work that it took to get to

Re: [Jython-users] Jython 2.7.3b1 Released

[Jim B. <jim...@py...>]

Jeff M.,

I would take a look at Jeff A.'s work on
https://the-very-slow-jython-project.readthedocs.io/en/latest/index.html to
see the design notes and some implementation details for what could be
Jython 3 core. This represents a much more sustainable effort that fits
into current Java's capabilities, at the risk of taking a very long time to
complete. However, I would suspect that a lot of the current library code
could be reused in some way.

Lastly, I see you are also in the Boulder area.

Re: [Jython-users] Jython 2.7.3b1 Released

[Jeff M. <jef...@za...>]

Any update on Jython3? Every once in awhile I do a quick check and it seems
pretty dead, but maybe I'm looking in the wrong git etc?

https://github.com/jython/jython3 is years old .. just an experiment I
gather

The main git is https://github.com/jython/jython it appears; not sure if
theres python 3 stuff mixed in there somewhere?

[Jython-users] Jython 3 and jsr223

Re: [Jython-users] how to run jython coverage with an explicit java.exe?

[Jeff A. <ja...@fa...>]

Hi Hartmut. Thanks for experimenting with solutions.

I've never used coverage myself, but when I run jython (on Windows) it 
picks up the JVM on my path.

I do not understand why, in your account of the error, 
coverage-script.py is in the Jython bin directory. I would expect that 
to be in site-packages, or somewhere of its own, and the paths to 
modules it needs would then be on the sys.path. The error about not 
being able to find a module does not scream "wrong JVM" to me.

pkg_resources is in site-packages, as part of the pip installation we 
do. However, pip as a whole is broken for all versions of Jython thanks 
to changes at pypi.org and our slowness to adapt. pkg_resources is not 
necessarily affected.

Running the jython.jar directly may not work well because additional 
JARs you may need are precluded by the -jar option. The jython.exe 
launcher has a --print command that tells you what it would have done, 
which is useful when you need to roll your own command line. --help will 
tell you which environment variables it pays attention to in creating 
that command.

[Jython-users] how to run jython coverage with an explicit java.exe?

[Niemann, H. <har...@si...>]

Hi!

I need to specify which java is used for a coverage run.

I am using Jython 2.7.0 and coverage 3.4.3

I used to use "coverage.exe" but how could I tell it which java to start?

I succeded starting "jython.exe  coverage-script.py" , but same problem: which java VM is used?

I can run Jython with an explicit JAVA executable and some simple example
%JAVA64% -jar "somepath\jython.jar" %JYTHON_DIR%\bin\hello.py

But when I combine these to

%JAVA64% -jar "C:\SIBAS32\JAVA_LIBS\jython\jython.jar" %JYTHON_DIR%\bin\coverage-script.py

I get
Traceback (most recent call last):
  File "C:\DEVTOOLS\Jython\2.7.0\bin\coverage-script.py", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

So I would need to convince coverage.exe or jython.exe to use the Java.exe I want, or teach java.exe -jar ... coverage-script.py where to look for the pkg_resources directory.

On
https://www.jython.org/jython-old-sites/archive/21/docs/interpreter.html
I found the sentence
"jython is a short script that invokes your local JVM, [..]"
which unfortunately does not tell me how the JVM is selected from the (four?) JVMs I have installed.

What would you recommend?

Regards
Hartmut

[Jython-users] Support for python 3

[Simon K. <sim...@do...>]

Dear Jython Users,

I can see that you have published a page with a roadmap to Jython 3 and that this question has been asked a few times in the past!

We use Jython in one of our products and some customers would like to have Python 3 scripting supported. So, can I ask about the status of Jython 3 and when support for Python 3 scripting might be released?

Many thanks,
Simon

[Jython-users] Python doc generation from Java source

[Nicolas F. <ni...@pn...>]

Hello Jython users,

We use Jython to allow our customers to write extensions for our software
written in Java. The public code is accessible in a jar, say *a.jar*, and
the javadoc bundle for that jar is say, *a.zip*.

Users writing non-trivial Python script extensions would like to use
full-blown IDEs like Eclipse+pydev or PyCharm. I was wondering how to
integrate javadoc as Python documentation within those projects: can those
IDEs somewhat take the javadoc zip and figure out what doc entry to fetch
and how to convert it from the javadoc html format?

Example: a.jar contains com/abc/Foo.class; a.zip has a javadoc entry for Foo
from com.abc import Foo
a = Foo()

I would like the IDE to know that the doc for com.abc.Foo is located in the
javadoc zip archive, fetch it and offer it to the user.

Do you know of any existing IDE plugin that could do that?

Thank you,

[Jython-users] How to configure setup.py to distribute egg

[James K. <jwk...@gm...>]

I’m using Netbeans with Python and jython plugins. I started a python
project and wrote my code. I import standard JAVA packages and only one
Java add-in

import gnu.io

import gnu.io.RXTXPort as RXTX      (RXTX is added to JDK/JRE and JRE I
assume this will be a dependency)

The program runs fine from within Netbeans and now I want to make an egg.

The project SRC folder contains 29 .py  + 25 .class + 7 .jpg + 2 .XML
files  and   __INIT__.py

I right-click the project and use CLEAN and BUILD EGG

This puts a setup.py file in the source directory and creates a built and
info folder.

I also issued the Jython command from within the project SRC
folder            jython setup.py  bdist_egg

Both methods run to completion and produce the following

<folder> build>

               <subfolder> bdist.java1.80_251     (which is empty)

+ <folder> dist

           <file> JythonProject0.1-py2.7.egg      (contents = list of
egg-info files)

+  <folder>JythonProject.egg-info  with

          <file>  dependency_links.txt          (no content)

          <file> PKG-INFO                                (summary of
setup.py entries)

          <file> SOURCES.txt                           (setup.py + list of
these files)

          <file> top_level.txt                           (no content)



I’ve studied about the structure of the setup.py file but I’ll admit that
without an example I’m left confused about the syntax of filling in the
blanks.

QUESTION: how do I add my source data to get a working egg?

Setup.py =

from setuptools import setup, find_packages



setup (

       name='JythonProject',

       version='0.1',

       packages=find_packages(),   ***  (supposed to find all .PY files ?)

                                                          *** how to
include CLASS files?

       # Declare your packages' dependencies here, for eg:

       install_requires=[],   *** my RXTX?  <path>xx.JAR?

       # Fill in these to make your Egg ready for upload to

       # PyPI

       author='jwkel',

       author_email='jwk...@gm...',

       #summary = 'Just another Python package for the cheese shop',

       url='', *** none

Re: [Jython-users] How to install pillow

[Stefan R. <ste...@gm...>]

Hello Régis,
Pillow appears to be largely written in C, looking at
https://github.com/python-pillow/Pillow/tree/master/src. C-extensions are
not supported by Jython. I once started the JyNI project to compensate this
gap, but I never tested Pillow and probably it wouldn't work with current
JyNI out of the box. Unfortunately I cannot afford to continue work on JyNI
in foreseeable future.
I think you'd be best off by using a Java-native imaging solution, e.g.
ImageJ. (However, I am not aware of how Pillow and ImageJ features compare
in detail.)
If it really must be Pillow, then Jython is probably not the right choice
for you. You'd like to try JEP, Py4J or JPY. There is also GraalPython, but
AFAIK its C-extension support is still fairly experimental. Probably still
worth a try.

Best regards

Stefan
