Now in extras-devel.

Currently Maemo5 has python2.5. There are some interesting python2.7 applications which can't be ported to N900.

Check python2.7-minimal from extras-devel.

*Packages are fully optified.
*Python2.5 and python2.7 can be simultaneously installed

There are no yet modules for python2.7, but in some cases it is possible to use modules from python2.5.

It is not intended that existing and working applications use python2.7, but if new application needs python2.7 it states that explicitly.

--------
First test: AdvancedCaching (this is existing application and works great with python2.5)

Code:

/opt/agtl-maemo/core.py
-#!/usr/bin/python
+#!/usr/bin/python2.7

+import sys
+sys.path.append('/usr/lib/pymodules/python2.5')
+sys.path.append('/usr/lib/pymodules/python2.5/gtk-2.0')
+sys.path.append('/usr/lib/python2.5/site-packages/')
+sys.path.append('/usr/lib/python2.5/lib-dynload/')

-> works.
---------
Some existing applications fail to start with python2.7, and I'm suspecting mismatch of old python2.5 modules, so maybe modules (or some of them) must be recompiled against new python. I'm asking You to test and report your thoughts. What modules cause errors?

----------------

[EDIT]
ctypes works with version 2.7.3~rc2-2.1-maemo6 (on extras-devel)

Is it really optified without the trickery used for Python 2.5?. That would be really a definitive improvement over current installation.

Have you tried to build it with Linaro toolchain and Thumb2?. It could give a boost to Python applications (specially startup times). Then, you could use CSSU's Thumb repository to upload this package (if freemangordon agrees).

Yes, it "just" installs itself to /opt/python27
("just" = You can count how many modifications and commits it took to achieve this.)

Not yet. I'm waiting instructions how to participate thumb2. I really respect extras-devel way, i.e. developers send source code and very same builder builds deb-packages.

This is an excelent news, because python 2.5 have any problem with any packages for example wifite_r85, pyrit and others. This required python 2.7. Wait that you compiled python2.7 completely and upload to repositories.

Here are some errors that usually come with some applications using python

with pyrit)

Code:

/home/user # pyrit
Traceback (most recent call last):
   File "/usr/bin/pyrit", line 4, in <module>
          import pyrit_cli
   File "isr/bin/pyrit_cli.py", line 32, in <module>
          import cpyrit.cpyrit
ImportError: No module named cpyrit.cpyrit

Something similar occurs with other packages
I would like to continue testing the improvements that are implemented with python

Regards.

@AapoRantalainen - check your debian/control file (along with others that may be affected) in the package you sent to autobuilder, it seems line endings are windoze style.

Hmm, what instructions do you need?

I did not have many issues with running wifite_r85 on python 2.5, more info check here.

I send debian/control.in and builder generates debian/control.

For testing I sent only debian-directory without source files, and then I get error log as expected. I will continue investigation.

there is debian/control in .tar.gz file you have sent to autobuilder. And this is what autobuilder tries to parse before executing debian/rules.
