Is it okay to include Python library code in twisted for purposes of
backwards compatibility. Two examples recently:
- Heapq is new in python 2.3. Therefore, regardless of whether we
modify it or not, if we use it, we either need to depend on python >=
2.3, or include a copy for compatibility purposes. It has a pure python
- yacc on IRC wanted to use tempfile.mkstemp. This only exists on >=
2.3. Again, pure python implementation.
Glyph: a pronouncement is necessary on whether, and under what
conditions, it is acceptable to include PSF-licensed code in twisted.
a) It is always okay. Copy freely from python into twisted.
b) It is okay, as long as the modules are included for backwards
compatibility only and can be removed as soon as the minimum required
version moves up to 2.3 (or whatever the latest and greatest version we
need modules from). Also the code under PSF must be segregated in a
c) It is okay <fill in the blank>
d) It is never okay.
As you can probably tell, my initial inclination is (b).
