[Jython-users] Problem with imports

[Sébastien B. <seb...@te...>]

    Hi all,

I have currently a problem with imports I do not understand.
This is what happens (Jython 2.7.0, java 1.8.0u66, on debian 8):

----8< ---- 8< ----
./jython.sh
Jython 2.7.0 (default:9987c746f838, Apr 29 2015, 02:25:11) 
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_66
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys; sys.path
['', '/path/to/XMCDA-java.jar', '/home/bigaret/lang/python/Lib', '/home/bigaret/lang/python/jython-standalone-2.7.0.jar/Lib', '__classpath__', '__pyclasspath__/']
>>> import org.xmcda.parsers.xml   # this one fails here....
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named xmcda
>>> from org.xmcda.parsers.xml.xmcda_3_0 import XMCDAParser
>>> import org.xmcda.parsers.xml   # ...but now it succeeds
>>> org.xmcda.parsers.xml
<java package org.xmcda.parsers.xml 0x2>
>>> sys.path
['', '/path/to/XMCDA-java.jar', '/home/bigaret/lang/python/Lib', '/home/bigaret/lang/python/jython-standalone-2.7.0.jar/Lib', '__classpath__', '__pyclasspath__/']
----8< ---- 8< ----


Note that the first import fails, while the last (which is the same statement) succeeds --and sys.path was untouched, there is just an import between the two identical imports)

Does someone has any hint why I get such a strange behaviour, or can point me to the right documentation to read? I could unfortunately not find any hint on such peculiarities when searching in jython's doc or on the web in general.

Thanks in advance,

__ Sébastien.


NB: The jython.sh is a simple bash script:

----8< ---- 8< ----
#! /bin/bash
JAVA=/usr/local/java8/bin/java
JYTHON_STANDALONE_JAR=/home/bigaret/lang/python/jython-standalone-2.7.0.jar
XMCDA_LIB="/path/to/XMCDA-java.jar"

export JYTHONPATH="${XMCDA_LIB}"

"${JAVA}" -cp "${JYTHON_STANDALONE_JAR}" org.python.util.jython
----8< ---- 8< ----

(and I have the same behaviour when adding XMCDA_LIB to the java '-cp' argument.

[Jython-users] Jython slow compiled with OpenJDK on Centos6.7

[Matt R. <mjr...@gm...>]

Hi all

I built Jython from latest source on linux using Open JDK 7, Python 2.7. I
easy_install virtualenv then create and enter a new environment. When I run:

import timeit
timeit.timeit('"-".join(str(n) for n in range(1000))', number=10000)

I wait something of the order of 6 seconds before completion. For
comparison it's about 5 seconds using the system python which is more or
less expected.

When I install a python package, namely the testing library robotframework
via this virtual environments pip, then the execution time increases to 20
seconds. When I run tests via robot or install any python packages, it
takes a lot longer than normal. So much so that the 4 times slower observed
on the simple timeit above would be an improvement for these tasks!

What could be possible reasons for such a drastic reduction in performance?

[Jython-users] jarray broken in Jython 2.7.0?

[Chris C. <Chr...@ac...>]

TL;DR I need a way to convert str type into a Java array of bytes type, jarray used to be the way to do this with all previous versions of Jython before 2.7.

I'm seeing a change in behavior in Jython 2.7.0 compared with Jython 2.5.3 related to jarray and bytes.

    Jython 2.5.3 (2.5:c56500f08d34+, Aug 13 2012, 14:48:36)
    [Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_67
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import jarray
    >>> sval = 'a string'
    >>> print type(sval)
    <type 'str'>
    >>> x = jarray.array(sval, 'b')
    >>>

Above works fine.

    Jython 2.7.0 (default:9987c746f838, Apr 29 2015, 02:25:11)
    [Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_67
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import jarray
    >>> sval = 'a string'
    >>> print type(sval)
    <type 'str'>
    >>> x = jarray.array(sval, 'b')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: Type not compatible with array type

Above fails :-(

I can't see anything in the docs about this. There is the new bytearray support in Jython 2.7.0 which appears to work for the above example:

    >>> x = jarray.array(bytearray(sval), 'b')

But this doesn't really work once things get more complicated.

    >>> sval = ''.join([chr(z) for z in range(0xff + 1)])
    >>> x = jarray.array(bytearray(sval), 'b')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    OverflowError: value too large for byte

I don't even know what too large might mean, it seems to be a problem with values above 128.

This is preventing blob/binary support from working in jyjdbc (https://bitbucket.org/clach04/jyjdbc/) with Jython 2.7.0, binary works fine in Jython 2.2 and 2.5.3.

Thanks,

Chris

Re: [Jython-users] converting java byte[] to Jython str/unicode

[Jeff E. <jem...@fr...>]

Since I use Jython primarily to script my Java application, I tend to use Java API's and would do it this way:

from java.nio.charset import Charset
from java.lang import String
s = str(String(aByteArray,Charset.forName('UTF-8')))

but I would omit the str() part and just keep the Java String and let Jython convert if and when it needs to.

s = String(aByteArray,Charset.forName('UTF-8'))

[Jython-users] converting java byte[] to Jython str/unicode

[Master Of T. <hi....@bt...>]

Hi,

I am having java byte[] available to me from JDBC driver which Id
like to convert to Jython str/unicode types (with specified charset when
converting to unicode eg. utf8).

Whats the best way to do this?

... unless of course its as simple as:

s_str = str(rs.getString(...))
s_unicode = str(rs.getString(...)).decode('utf8')

[Jython-users] how to do AJAX http-post (URLEncoded) from jython?

[Fernando C. <fc...@gm...>]

Hi there,

I worked on a script to scrap some information from a web site.
Before, I just used a shell script that called wget with the right
parameters to do a session log-in, retrieve the session cookies, then
afterwards perform the required calls to several .php scripts to
retrieve the info I wanted to a file on disk, which I ten parsed.

BUT the server changed its code, and while the URLs for the PHP
scripts remain the same, what was passed before as HTTP-GET requests
is now handled via POST URLencoded AJAX requests, and the server is
refusing http get requests so  my scripts work no more.

Q: what would be the easiest way to redo my scripts in Jython,
particularly, is there any built-in code to deal with ajax POST
requests, and urlencode? or any third party Java library that is known
to work well from Jython?

Thanks in advance.

Re: [Jython-users] Cannot Install Sphinx1.3.3 Into Jython2.7.0

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

David,

Thanks for this experience report! It's great to hear that Sphinx works
without problems for you, once you applied the workaround you found. We
still want to fix the failing Sphinx tests (see
http://bugs.jython.org/issue2288), but I suspect these are edge cases for
Python compatibility at this point for Jython.

re os.makedirs - in general, I have found the Java-based solution found as
part of Java 7 is very robust (especially on Windows). The one change I
would make in your solution is to use
https://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#createDirectories(java.nio.file.Path,%20java.nio.file.attribute.FileAttribute...),
so you can get the mode set. Making this be the default implementation in
the os module makes sense to me.

Lastly, it would be great if you could submit a bug report, including
traceback, etc, so we can trap the error you are seeing and turn it into an
appropriate OSError, with errno properly set.

- Jim

Re: [Jython-users] Cannot Install Sphinx1.3.3 Into Jython2.7.0

[David C. <dav...@gm...>]

Here I am, reporting back as I now have *working* Sphinx documentation for
my Jython+JavaFX project!  Thank you for your support.

The root issue seems to have been the OS.  I upgraded the server from
Ubuntu 12.04.5 to Ubuntu 14.04.4 and was able to install Jython 2.7.0
without the 'passwd.pw_passwd' exception.

After the fact, I discovered that I was using this java:

$ java -version
java version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

And that the JAVA_HOME environment variable was unset.

I was able to install Sphinx1.3.3 into this Jython instance and generate my
documentation after overcoming only a few additional obstacles.

1.  os.makedirs() failed for me.  I replaced the default implementation of
os.makedirs() in $JYTHON_HOME/Lib/os.py with this and was able to keep
moving:

    import java.io.File
    return java.io.File(name).mkdirs()

My own failure of os.makedirs() looked exactly like this issue:
http://bugs.jython.org/issue1885

2.  To get my JavaFX-dependent modules to import, I had to do some hackery
on the headless server to ensure that the JavaFX runtime was already
running, and running in headless mode with Monocle.  (But, that has nothing
to do with Jython.)

Thanks again for your support and for the great platform that is Jython.
This story has a happy ending.

David

Re: [Jython-users] Help with broken code

[Rafael B. <be...@hs...>]

First of all, I appreciate your continued interest in helping me with the problem.  I am using jython2.7.0.  I’ve tried the program on two versions of the Mac OS, El Capitan and an older version on another computer (I don’t recall the number off hand).   

I’ve been swamped with work the last couple of days, so I haven’t had a chance to try your suggestions, but I will soon.  I will post my result on the mailing list.  Meanwhile, I continue to welcome any new insights on the problem.

Cordially,
Rafael

Rafael, sorry, I had read your email too quickly and had misconcepted the issue in the sense
that the window would not display at all. (That's why I suggested to call frame.show
and try the JOptionPane-based test program.)
Given that the window actually *does* display makes my suggestions rather irrelevant I suppose.

However, I can also not reproduce the *actual* issue on my system - here the button causes
the console to print "Clicked!" as expected (using Jython 2.7.1 beta 3 and Java 7).
Maybe you can first check that it's not a console issue: Let the click change the button-
or frame capture instead. Does ordinary console printing work?
What Jython- and Java version are you using?

Hello Rafael,

trying your program on linux, it works like expected.
However, did you try to call frame.show()?
(maybe instead of frame.visible = True)

If this also fails, can you confirm that the equivalent Java-program would work?
Given that it works on my setup, it is possible that on your system
something with Java is broken rather than with Jython.

In case you don't speak Java, try the trivial swing program:

from javax.swing import JOptionPane
JOptionPane.showInputDialog("Hello Jython");

in Java:

public static class TestSwing {
  public static void main(String[] args) {
    javax.swing.JOptionPane.showInputDialog("Hello Jython");
  }
}

If this works in Java, but not in Jython, I'd suggest to file an issue on bugs.jython.org.
Also helpful: Did you apply some specific change that broke the program? Some update of
Java or Jython, or some System update? Every information about what caused the breakage
is helpful.

Best

Stefan

Re: [Jython-users] Help with broken code

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

Hello Rafael,

trying your program on linux, it works like expected.
However, did you try to call frame.show()?
(maybe instead of frame.visible = True)

If this also fails, can you confirm that the equivalent Java-program would work?
Given that it works on my setup, it is possible that on your system
something with Java is broken rather than with Jython.

In case you don't speak Java, try the trivial swing program:

from javax.swing import JOptionPane
JOptionPane.showInputDialog("Hello Jython");

in Java:

public static class TestSwing {
  public static void main(String[] args) {
    javax.swing.JOptionPane.showInputDialog("Hello Jython");
  }
}

If this works in Java, but not in Jython, I'd suggest to file an issue on bugs.jython.org.
Also helpful: Did you apply some specific change that broke the program? Some update of
Java or Jython, or some System update? Every information about what caused the breakage
is helpful.

Best

Stefan

The demo program below used to work, but now, when the button is clicked, nothing happens, although the window displaying the button does open just fine.  I run it in the Macintosh Unix terminal.  Any assistance with this problem would be greatly appreciated.

Rafael Bejarano

from javax.swing import JButton, JFrame
frame = JFrame('Hello, Jython!', defaultCloseOperation = JFrame.EXIT_ON_CLOSE, size = (300,300))
def change_text(event):
	print "Clicked!"

button = JButton('Click Me!', actionPerformed=change_text)
frame.add(button)
frame.visible = True

[Jython-users] JyNI 2.7-alpha.3 released!

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

Following up on the recent release of Jython 2.7.1 beta 3
I am proud to announce the release of JyNI 2.7-alpha.3.

Take a look at

jyni.org

or go directly to the release:

https://github.com/Stewori/JyNI/releases/tag/v2.7-alpha.3

Binaries are provided for target platforms JyNI is tested on.
It should in principle be buildable/workable also on other posix platforms.

Main new features are:

* OS-X support
* CPython-compatible garbage collection of native objects
* capable of loading ctypes (core functionality tested)


What comes next?
----------------

With this release I updated jyni.org/#roadmap; take a look to
learn about plans for alpha.4, alpha.5 and beta.1.
However, before I continue work toward alpha.4 I will check
some Python frameworks that have ctypes-only native dependency
for workability (e.g. PyOpenGL).


Wish List
---------

With this release I also introduce the Wish List section
jyni.org/#wish-list.
The intention of this list is to focus on actually *needed* API
with priority before attempting exhaustive API support.
If you have desire for a specific extension to work, send me a mail
regarding jyni.org/#wish-list and I will check whether your
extension is a "low hanging fruit" that can be supported via
minor improvements. Especially extensions from the above mentioned
category of ctypes-only-dependency highly qualify.


Enjoy!

[Jython-users] jython2.7.0 DATE issue

[Tami T. <tta...@us...>]

Last year, I posted a question on zxJDBC + jython2.7.0 DATE issue, but it 
was not really a zxJDBC issue.

Instead, there seems an issue somewhere in JTable-related code. 
When I ran the attached code with Jython 2.7.0, I see "2015-12-30" and 
"2015-12-31", which should be  "2015-12-31" and "2016-01-01".
When  I ran the attached code with Jython 2.5.3, I see correct results.

Can I report this as a bug?

[Jython-users] PyVmMonitor 1.0.1 released

[Fabio Z. <fa...@gm...>]

PyVmMonitor 1.0.1 is now available for download

*Release Highlights:*

   - Pstats files may be passed in the command line to be opened in
   pyvmmonitor-ui.
   - Fixed issue opening PyVmMonitor in Mac OS (El Capitan).
   - Opening PStats file may fail because it's linked to a Python version,
   so, in such a situation, PyVmMonitor allows opening it using a different
   interpreter.
   - Command line examples are properly wrapped with quotes on Windows.

See: http://www.pyvmmonitor.com for more information.

*What is PyVmMonitor?*

PyVmMonitor is a profiler with a simple goal: being the best way to profile
a Python program.

*Features*

   - Attach profiler to a running (CPython) program
   - Deterministic profiling through cProfile/profile integration
   - On demand profiling with Yappi integration
   - Analyze existing PStats results
   - Open DOT files
   - Programatic API access
   - Profile on a different machine
   - Multiple processes support (multiprocessing, django...)
   - Live sampling/CPU view
   - Select time range
      - Group samples by method or line
   - PyDev integration
   - PyCharm integration

Enjoy!

[Jython-users] problem with zxJDBC and clobs

[Jon C. <jon...@gm...>]

I've run into a problem with zxJDBC and clobs.  The code:

from com.ziclix.python.sql import zxJDBC as DBAPI
...
 crs.execute("update session set xml=? "
                "where "
                "id=1",
                [xml_clob],
                {0:DBAPI.CLOB})


Generates the error:

   crs.execute("update session set xml=? "
   Error: ORA-01461: can bind a LONG value only for insert into a LONG
column
   [SQLCode: 1461], [SQLState: 72000]



I have to use the actual clob datatype here, as using the STRING data type
produces:

   crs.execute("update session set xml=? "
   Error: error setting index [1], type [12] [SQLCode: 0]
   setString can only process strings of less than 32766 chararacters
[SQLCode: 17157]

The problem is no longer critical to me as I've managed to work around it
by using direct JDBC calls:

   ps=db.__connection__.prepareStatement("update session set xml=? "
                                          "where "
                                          "id=1"
                                          )
    ps.setStringForClob(1,xml_clob)
    ps.executeUpdate()


However, even with that workaround, I'm a bit nervous as to if that
statement executes in the same transaction as the others.

Is the zxJDBC clob code broken, or am I somehow using it incorrectly?

FWIW, I'm running Jython 2.7.0 installed via brew on Mac OS 10.10.5.

Thanks for any help you can provide.

[Jython-users] PyDev 4.5.1 Released

[Fabio Z. <fa...@gm...>]

Release Highlights:
-------------------------------

* Debugger

* Cython speedup modules are now available for the debugger (see
performance improvements at:
https://www.speedtin.com/reports/7_pydevd_cython).

* It is considerably faster even without the speedup modules (see
performance improvements at:
https://www.speedtin.com/reports/8_pydevd_pure_python).

* When debugging multiple processes the console wasn't being updated to the
selected stack in the debug view.

* Many bug-fixes.

* Improved the search to always play safe and update the index so that the
matches are always consistent (#PyDev-634).

* Fixed issue renaming top-level module on refactoring.

* Refactoring has option to rename variable to a standard case style.

* Improved the parser that extracted the outline for global tokens to deal
with async and consider declarations inside ifs.

* Code completion of properties with @property no longer shows arguments
parenthesis (#PyDev-453).

* Preventing a freeze if some code-analysis takes too much time
(#PyDev-636).

* Ctrl+1 can be used to wrap/unwrap the contents of brackets (patch by
yohell).
