jython-dev — Discussion of developing and enhancing Jython itself(!) (not how to use Jython)

Re: [Jython-dev] Jython 2.7 rc2 soft launch

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

We need help on the following multifactor testing, which I will explain in
more detail below:

   - Test on different operating systems and distributions, and their
   versions, including especially Windows, but also Linux (RHEL, Fedora,
   Ubuntu) and BSD variants. To be honest, I don't know what it would be on
   platforms like AIX, HPUX, and Solaris; and even less so on platforms like
   AS/400. However, Jython does code to support all of the above, so it's
   worth testing if you care about a given OS. Note that S/390 remains
   unsupported until we get feedback from S/390 users (
   http://bugs.jython.org/issue550200); but in theory this could be done in
   a future release, since JRuby has this support.
   - Different JVMs, including J9.
   - Internationalization, especially those using non Latin-1 characters.
   We have found and fixed issues in the past with Finnish, Japanese, and
   Turkish, but this may to extend to other languages and their corresponding
   locales.
   - Different installation logic - GUI, console, command line - supported
   by the installer
   - Choosing to install or not pip/setuptools in the installer
   - CPython 2.7 is and is not available; if so, it is used by the new
   jython.py launcher (implicitly used on Windows for jython.exe)
   - Using the pip (or easy_install) installed by ensurepip to install
   different types of tools that create executable scripts (so nose vs yolk)

Some details on what was changed for RC2; it's a bit much to read I agree,
but hopefully it explains the extent of what needs to be tested. RC2
includes changes for:

   - the installer itself
   - pip support, for Japanese locales, and perhaps other
   - setuptools, for Windows, to build executable scripts that use the
   older setuptools approach vs the newer distlib approach

New features in the installer:

   - Installer installs pip, setuptools by default, but custom builds can
   de-select. This does not change standalone usage. (Runs jython -m ensurepip
   as last install step.)
   - Installer makes jython.py be the default launcher (as bin/jython) if
   CPython 2.7 is available. On some platforms like RHEL 5, where CPython 2.7
   is not readily available, the old bash-based version of Jython is used.
   - Installer no longer supports using an alternative JRE when generating
   Jython launchers. Instead it 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.)

The installer itself supports three different use cases, with different
logic paths for determining what the user would like to have installed. All
three logic paths had to modified, so these need to be tested as well:

   - GUI installer. This installer is selected automatically if Java can
   connect to a GUI environment.
   - Console installer. This installer is the default without a GUI
   environment available. The text console prompts for options to be installed.
   - Command line installer. No interaction with the user.

Help is available about these installer options with
java -jar jython-installer-2.7-rc2.jar --help

Re: [Jython-dev] Jython 2.7.0 Release Candidate 2

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

Re timing of the soft RC2: the last dependency is updating NEWS so that it
reflects the work that has been done during the release candidate cycle. I
expect to have this complete in the next few hours, then Frank can put
together the release.

Re: [Jython-dev] Jython 2.7.0 Release Candidate 2

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

Peke,

I'm glad you asked! Curiously enough I did do some of this installer
testing while riding a bus without any internet connectivity (left my usual
hotspot at home), and it worked just fine. This is explained by the way
ensurepip works: ensurepip uses bundled wheels for setuptools and pip, so
no internet connectivity is used. You can also see this with the log
message ensurepip emits: Ignoring indexes: https://pypi.python.org/simple/

Likewise pip can be used for other offline access, but it becomes
substantially more interesting when it can access the PyPI site or a
suitable mirror. That's also why it needed suitable SSL support, as
provided by the socket-reboot work that took so much time last year.

Does "jython -m ensurepip" require network connection or are all
needed modules bundled in the installer?

Re: [Jython-dev] Jython 2.7.0 Release Candidate 2

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

These installer bugs are now fixed. We should be ready to try another soft
release candidate.

In addition, the Jython installer now will install setuptools and pip by
default (runs jython -m ensurepip) except for standalone jar (doesn't make
sense). One can also deselect this installation in the custom install.

This is a work-in-progress port of the CPython dev guide. It's a great
format, and contains useful information for a new developer, but it's less
in-depth about Jython internals than the above guide.

Yes.

Please file a bug against http://bugs.jython.org/ so we can track if you do
so. Pull requests by themselves really don't have the context we need,
especially for prioritization. (Occasionally I have committed a lower
priority change as we wrap up 2.7.0, but I'm trying to stay disciplined and
focus only on urgent bugs at this point.)

FWIW, the use of bitbucket for PRs is discouraged because it's really time
consuming to get a usable diff that we can commit, just due to how
hg.python.org is managed.

Lastly, I personally consider myself a terrible, nonscalable select loop ;)
- there's more email, pull requests on github and bitbucket, bugs, tweets,
IRCs, etc, than I could ever respond to, and that's just my Jython work.
Other Jython developers here are in the same situation.


> I'm struggling with mercurial at the moment.

One goal of the next dev cycle (2.7.1) is to transition to
https://github.com/jython - as you can see it's waiting to be filled in.
Something we will work on during the PyCon sprints for sure!


> 3. Any recommendations of easy issues that I can try to fix ?
> I was thinking maybe
> http://bugs.jython.org/issue1376 ?

That's a good one, because it does go into internals, such as __dir__ vs
__rawdir__, but it's not so difficult either. Trace this through its
implementation in PyObject and other places that override it in the
inheritance hierarchy. Good luck, we hope to see a good PR! Specifically if
you do tackle http://bugs.jython.org/issue1376, mention your PR there.

One more thing: the best way to get help is to hang out on #jython on
freenode and ask questions - and ideally answer them!

[Jython-dev] Questions on Getting Started

[Gautam K. <gau...@gm...>]

Hi,

I'm trying to get started with contributing to Jython, I have a few
questions,

1. Which Developer Guide is considered the primary ?

https://wiki.python.org/jython/JythonDeveloperGuide
 OR
http://www.jython.org/devguide/ ?

2. I noticed that there was a github (https://github.com/jythontools/jython)
mirror, Is it
being actively used ?
Would it be alright if I fork and sent patches as pull requests ?
I'm struggling with mercurial at the moment.

3. Any recommendations of easy issues that I can try to fix ?
I was thinking maybe
http://bugs.jython.org/issue1376 ?

Gautam

[Jython-dev] Jython 2.7.0 Release Candidate 2

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

We have identified the following four bugs that need to be fixed for the
next release candidate of Jython 2.7.0:

http://bugs.jython.org/issue2297 - the installer on Windows currently
assumes that jython.bat still exists, instead of its replacement, a native
jython.exe installer. This problem slipped through because we were not
testing the installer on Windows, assuming it was not platform dependent.

I also plan to make the new Jython launcher script, src/shell/jython.py,
which is wrapped as jython.exe by PyInstaller, be the default launcher on
non-Windows platforms if CPython 2.7 is available, since we are going to be
touching this codepath in the installer to fix this jython.bat vs
jython.exe issue. Also, since the installer is touched, we should be able
to add automatic installation of ensurepip.

http://bugs.jython.org/issue2300 - the new Jython launcher (jython.py)
currently swallows arguments. jython.py uses argparse, but the arg parsing
needs more help because jython.py is then used as the launcher for tools
like pip, yolk, etc. I have a fix that's almost ready to go.

http://bugs.jython.org/issue2298 - setuptools currently doesn't check if
the underlying platform is Windows, so it uses the wrong approach for
building executable scripts. This is an easy fix, and we fixed the same
issue in distlib. We are going to build our own wheel for now that we
bundle as part of ensurepip, however I've been in contact with Jason
Coombs, maintainer of setuptools to get this upstreamed once we have
finalized our fixes. Vinay Sajip, the maintainer of distlib, is also
working on an upstream fix for the changes we need.

http://bugs.jython.org/issue2301 - ensurepip fails on Japanese locales,
because of a problem in logging timestamps from the ensurepip module. Such
timestamps are written like "日 3/29 14:55:13 2015". Naturally the last
thing we want is for logging to cause failures like this! Should be an easy
fix.

So three fairly small bugs, plus one with straightforward changes to the
installer. I hope to see a soft availability of the RC2 in the next few
days.

Re: [Jython-dev] Jython 2.7 rc1 soft launch take 2

[<fwi...@gm...>]

OK, here are the official release links:

standalone: http://search.maven.org/remotecontent?filepath=org/python/jython-standalone/2.7-rc1/jython-standalone-2.7-rc1.jar
installer: http://search.maven.org/remotecontent?filepath=org/python/jython-installer/2.7-rc1/jython-installer-2.7-rc1.jar

I have not announced because there is a severe windows issue. I will
announce later (maybe tonight) once a workaround is found, so we don't
get flooded with bug reports on it.

Re: [Jython-dev] Jython 2.7 rc1 soft launch take 2

[<fwi...@gm...>]

I accidentally included some extraneous files in the first soft
launch. I've put up a new one. Since no one has found any trouble with
the first try, I'll leave this up for just 24 hours and then make it
the real rc1 unless something bad comes up.

The releases:

Installer: https://oss.sonatype.org/content/repositories/orgpython-1041/org/python/jython-installer/2.7-rc1/jython-installer-2.7-rc1.jar

Standalone: https://oss.sonatype.org/content/repositories/orgpython-1042/org/python/jython-standalone/2.7-rc1/jython-standalone-2.7-rc1.jar

The parent directories of each of the above have the checksums, source
jars, javadocs, etc.

[Jython-dev] Jython 2.7 rc1 soft launch

So finally, we are on release candidates!

The releases:

Installer: https://oss.sonatype.org/content/repositories/orgpython-1038/org/python/jython-installer/2.7-rc1/jython-installer-2.7-rc1.jar

Standalone: https://oss.sonatype.org/content/repositories/orgpython-1039/org/python/jython-standalone/2.7-rc1/jython-standalone-2.7-rc1.jar

Re: [Jython-dev] Planning a Release Candidate for Jython 2.7.0

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

All urgent bugs have been fixed, along with some bugs that should have been
marked as such. I would like to highlight the last fix, by Santoso Wijaya,
in https://hg.python.org/jython/rev/b597f478d5ab:

Introduce and use an overloaded non-buffered readinto() method
> for BufferedReader when #read(int size) is given an explicit size to read

This changeset fixed a problem with relative seeks of files, and how that
interacted with buffering; see http://bugs.jython.org/issue1793

We are now ready to build the 2.7.0 release candidate. Expect this to be
available very shortly!

[Jython-dev] Google Summer of Code

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

Jython plans to participate in the Google Summer of Code for 2015. If you
are interested, I have outlined a number of projects on our ideas page that
students could work on:

   - Work on JyNI, which adds C extension API support to Jython
   - Performance optimizations, including startup time
   - Python bytecode compiler for Python source (must be written in Java!)

See https://github.com/jythontools/gsoc2015 for the ideas page. Pull
requests and comments gladly accepted to expand this list of ideas.

The ideal student must be a very strong Java developer, with an existing
track record of projects on such sites as GitHub and BitBucket. Knowledge
of C and especially of the CPython source code invariably helps. Ideally
you will also become a Jython committer as a result of your intense
participation this summer.

Note that the deadline for student proposals is very soon, Friday March 27.
I apologize we are just getting our participation for GSOC together, but we
have also been busy finalizing the Jython 2.7.0 release candidate.

Re: [Jython-dev] Jython 2.7

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

I expect this week we will have a soft release of the release candidate. I
have postponed or fixed the remaining urgent bugs that require code
development. Now the only remaining bug is packaging,
http://bugs.jython.org/issue2282, which requires a change in the build.xml.
However, if it proves to be too hard it will also get postponed, since a
workaround does exist AND we are going to update packaging in a future
release, namely support of Maven builds with
