1) setuptools eggs
- Have to support legacy meta-data format
2) bdist
- Need to add python version for:
- compatibility info
- also provides delimeter between version # and platform
- Need to update setuptools/distribute to handle (or ignore) them.
3) New egg-like format "pbd"
- Arrange suffix so ignored by setuptools/distribute
- new-style meta data
- would be a zip file
- Essentially, .egg format with new-style meta data and different
suffix.
Option 3) looks the best to us, so we propose:
- Introduce a new binary distribution format with a ".pbd" suffix
and an egg-like structure.
An example file name:
ZODB3-3.10.0b1-py2.6-macosx-10.4-x86_64.pbd
- Deprecate bdist format.
D2/p will not support generation or installation of bdist
distributions.
In terms of distribution format, this sounds great; I think a clean
break and new format that existing systems will just naturally ignore is
the way to go.
Your message doesn't address the on-disk installed format. I hope that
the installed format (at least the d2/p default) will be consistent with
PEP 376 (unzipped and "flat"), not an egg-style importable zip file
relying on its own dedicated entry in a pth file.
yeah the installation format is PEP 376 for *all* distributions,
including the old ones:
whatever gets installed is converted into PEP 376 if it's not a
distutils2-based project
We're only talking here about a replacement for a binary *distribution*.
distutils' bdist is broken (the name of the file does not contain the py
version...) while
setuptools' egg would be a decent choice, it adds more legacy burden.
I am excited we had that discussion with Jim, 3) seems the way forward
for us.
