[matplotlib-devel] Matplotlib PPA

[Thomas K. <th...@kl...>]

As a couple of people have noticed, my matplotlib-daily PPA has become
broken the other day, especially for 64-bit users. The root cause of this
is that building the docs now requires numpydoc, which is only packaged in
the development release of Ubuntu.

I've taken this as a prompt to switch the daily recipe builds to raring. I
think most people who had added my PPA were interested in a Python 3
package of matplotlib. So I've backported the 1.2.0 package to precise and
quantal, in another PPA:

https://launchpad.net/~takluyver/+archive/python3

If you were using python3-matplotlib from my PPA on precise or quantal, I
recommend that you switch to my python3 PPA. It's actually a downgrade, but
it's a stable version that shouldn't do anything unexpected.

If people want to keep running development versions of matplotlib on
precise/quantal, speak up: I can reconsider turning off the daily builds
for those versions.

Thanks,
Thomas

Technical detail, for anyone interested: the architecture-independent -data
and -doc packages are built on i386. When the docs fail to build, the -data
package isn't created. The amd64 build succeeded, but the
architecture-dependent packages require a precisely matching version of the
-data package. apt complains that python[3]-matplotlib has a missing
dependency.

Thanks.  Sorry about not communicating the new dependency very well.  As 
this only affects those building the docs (meaning primarily developers 
and not end-users) it wasn't given the same care.

We had had some back-and-forth about whether to include a local copy of 
numpydoc in matplotlib, but ultimately decided not to as this is 
generally not what packagers like to see.  In there a way to depend on 
numpydoc from the development release in your PPA (only as a build-time 
dependency?)

That's fine. I think I did see the discussion, but I didn't pay it much
attention.

If we want builds for pre-raring versions, I think the way to do it would
be to backport the numpydoc package, and put it in the PPA - it will use
packages in the same PPA to satisfy build dependencies. This is easy enough
to do if people want it, I'm just aware that each build runs for the best
part of an hour*, on two architectures times however many releases we
target. If people are actually interested in running the daily packages,
that's worth doing, but if not, I don't want to tie up Launchpad's build
farm. My own use was the Python 3 package, which 1.2.0 can now meet.

*If that seems like a long build time, it has to set up build dependencies,
build and test four times (Python 2 & 3, normal & debug), and build the
docs. It's about an hour on i386 (which does the docs), and about half an
hour on amd64.
