Bug#939303: matplotlib2: FTBFS unsatisfied b-d

2019-09-10 Thread Rebecca N. Palmer 

Control: tags -1 patch

The dependency chain involved is

matplotlib2 -> python-mpltoolkits.basemap -> python-pyproj, python-pyshp

where all but the first no longer exist as Python 2 packages (and pyproj 
has also moved to a Python 3 only new upstream version).


Searching the code suggests that matplotlib2 no longer uses basemap 
(doc/pyplots/plotmap.py no longer even exists), and hence that a fix is 
to simply remove the build-dependency:

The package builds and passes autopkgtests with this, but that's all the 
testing it's had.  (The build-time tests are skipped with TypeError: 
object of type 'MarkDecorator' has no len().  I suspect this is an 
unrelated incompatibility with the current version of pytest, but 
haven't investigated.)

Bug#939303: matplotlib2: FTBFS unsatisfied b-d on python-pyshp

Version: 2.2.3-6
Severity: serious
Justification: fails to build from source

Hi,

src:matplotlib2 currently FTBFS because its build dependencies cannot be
satisfied in Debian unstable. It follows some evidence:

Or the debcheck results:

https://qa.debian.org/dose/debcheck/src_unstable_main/1567400407/packages/matplotlib2.html

This failure is also important, because matplotlib2 is necessary to
compile build-essential. See the dependency graph here:

Thanks!
