[Numpy-discussion] Removing datetime support for 1.4.x series ?
Thu Feb 11 18:46:23 CST 2010
Does anyone think it's a good idea to provide any support for numpy
version selection, similar to wxPython's wxversion? What it does is
allow an installation to have default version that gets imported with
"import wx". Optionally, other versions can be installed, and selected
before the first "import wx".
This was added to wxPython when there was a lot of API breakage going on
(I think during the 2.4 - 2.6 transition). It's nice, because you can
have a set of installed utilities that rely on a given version, and then
develop your new stuff with a newer version without breaking anything.
In numpy's case, it might be messier, as there are a lot more packages
that depend on numpy, but it could still be helpful, and in fact, maybe
more necessary. Older versions of the MPL wx back-end were compiled
against specific versions of wx, and wxversion was helpful for that.
Anyway, it seems the big isuue is when an ABI-incompatible version of
numpy gets released, you can't even install it until you re-compile all
the packages you may have that are built against numpy. With version
selection, you could install and mess with it without breaking any
It may be that virtualenv (and friends) is the "right" way to handle
this now, however -- it wasn't around when wxversion was developed, and
it may be a better way to keep a whole stack of packages compatible.
Any point in thinking more about this?
