Bug 271545 – Portage v2.1.6.11 does not require correct version of python

• Status: VERIFIED FIXED
• Product: Portage Development

[Description Mike Duncan 2009-05-28 15:24:43 UTC]

Portage v2.1.6.11 does not require Python v2.5 or above. Because portage now uses the IncrementalEncoder (http://www.python.org/doc/2.5.2/lib/incremental-encoder-objects.html) within the codecs module, a version of 2.5 or higher is required for portage to function **at all**.

Reproducible: Always

Steps to Reproduce:
1. equery list | grep python
sys-apps/python-2.4.3-r1
dev-python/pycrypto-2.0.1-r6
dev-python/python-fchksum-1.7.1
2. grep python_dep /usr/portage/sys-apps/portage/portage-2.1.6.11.ebuild
python_dep=">=dev-lang/python-2.4"
DEPEND="${python_dep}
RDEPEND="${python_dep}
3. emerge -v portage
...
4. emerge --info
Traceback (most recent call last):
File "/usr/bin/emerge", line 29, in ?
import _emerge
File "//usr/lib/portage/pym/_emerge/__init__.py", line 26, in ?
import portage
File "//usr/lib/portage/pym/portage/__init__.py", line 8215, in ?
_ensure_default_encoding()
File "//usr/lib/portage/pym/portage/__init__.py", line 7796, in _ensure_default_encoding
encodings = _gen_missing_encodings(missing_encodings)
File "//usr/lib/portage/pym/portage/__init__.py", line 7706, in _gen_missing_encodings
class AsciiIncrementalEncoder(codecs.IncrementalEncoder):
AttributeError: 'module' object has no attribute 'IncrementalEncoder'

Actual Results:  
All portage utilities, including emerge, ebuild, and equery, all produced these results with python-2.4.3-r1 and portage-2.1.6.11 packages installed.

Traceback (most recent call last):
File "/usr/bin/emerge", line 29, in ?
import _emerge
File "//usr/lib/portage/pym/_emerge/__init__.py", line 26, in ?
import portage
File "//usr/lib/portage/pym/portage/__init__.py", line 8215, in ?
_ensure_default_encoding()
File "//usr/lib/portage/pym/portage/__init__.py", line 7796, in _ensure_default_encoding
encodings = _gen_missing_encodings(missing_encodings)
File "//usr/lib/portage/pym/portage/__init__.py", line 7706, in _gen_missing_encodings
class AsciiIncrementalEncoder(codecs.IncrementalEncoder):
AttributeError: 'module' object has no attribute 'IncrementalEncoder'


Expected Results:  
Portage utilities should work normally.

To fix this issue after the install of portage-2.1.6.11, I needed to manually install python some where on the system and use that version to firstly uninstall the python package and then install the newer python v2.5+ package. You need to uninstall python first because of a file conflict with the python-updater binary now in a separate package from python.

Thanks, I've updated the dependency in CVS.

Hi, Portage 2.2_rc33 works with dev-lang/python-2.4.4-r15
so could python_dep be changed to:

python_dep=">=dev-lang/python-2.4.4-r15" ?

I'll later check what about dev-lang/python-2.4.6

No. It doesn't work.

$ grep -r IncrementalEncoder . | grep -v /\.svn/
./pym/portage/__init__.py:              class AsciiIncrementalEncoder(codecs.IncrementalEncoder):
./pym/portage/__init__.py:                      incrementalencoder=AsciiIncrementalEncoder,

Right.. Thx for clarification.
