py-libxml2 does not install libxslt module

[sfiera@…]

The current version of the py-libxml2 module works by extracting specific portions of the libxml2 package. This doesn't include the libxslt module, though. There's a python-specific package available, which will be used by this portfile:

We need to do what the FreeBSD folks did. Remove python bindings from libxml2. The patches to do this could be directly cribbed from theirs. Then the same thing needs to be done for port libxslt AND then a new py-libxslt created since one does not exist in DP. This is just like FreeBSD did so you have:

libxml2 libxslt py-libxml2 py-libxslt

and no conflicts between them. This would take care of this bug and 5255 and 5355 as well. It would be a quick job for a motivated person. Anyone?

so you'd have:

libxml2 libxslt py-libxml2 py-libxslt

Then again, is there a good reason that libxml2 and py-libxml2 cannot be combined into one? I'm just wondering if it is really necessary to have 4 ports instead of a libxml2 and libxslt that also install their python support by default, or maybe as a +python variant for each. I don't know why the FreeBSD folks chose to use a separate port so I guess all options should be considered.

I think that a variant would currently be a bad idea since AFAIK, one can't depend on a variant and some installations may fail due to that (e.g. if some user needs the variant but hasn't chosen it).

Perhaps because it would take more memory and would need more dependencies. For instance, "port info py-libxml2" says that it depends on python24. I certainly don't want to be forced to install python24[*] just because I want libxml2.

[*] meaning more maintainance, more compilation time, more disk space and more risk of install failure for someone who doesn't need python.

Yeah you're right. I was up late last night and guess I wasn't thinking so well this morning. The reasons seem perfectly clear now. Now if only someone who's interested will take an hour or so and just mimic the FreeBSD patches for libxml2 and libxslt and then make a py-libxslt port. I 've done enough bug squashing for now.

As far as I can tell, libxslt does not itself have the ability to build the python bindings - there is no setup.py included with it. The current py-libxml2 portfile already does what you suggested, though, and it would probably be possible to tweak the above portfile such that it would depend on py-libxml2 and only install the libxslt bindings.
