Subject: [python-numpy] Undefined symbols on several architectures

Date: Thu, 31 Aug 2017 09:15:14 +0200

Package: python-numpy
Version: 1.12.1-3+b2
Severity: serious
Affects: src:casacore

On several platforms, numpy cannot be loaded successfully due to missing
symbols:

    import numpy as NUM;
  File "/usr/lib/python2.7/dist-packages/numpy/__init__.py", line 166,
in <module>
    from . import random
  File "/usr/lib/python2.7/dist-packages/numpy/random/__init__.py", line
99, in <module>
    from .mtrand import *
ImportError:
/usr/lib/python2.7/dist-packages/numpy/random/mtrand.aarch64-linux-gnu.so:
undefined symbol: PyFPE_jbuf


The symbol that is reported as undefined varies between the platforms:

* arm64, s390x, alpha, hurd-i386: PyFPE_jbuf
* mips, mipsel, ppc64el, powerpc, ppc64: PyFPE_counter

These errors cause FTBFS for the "casacore" package:

https://buildd.debian.org/status/logs.php?pkg=casacore&ver=2.3.0-4

Got that error on amd64, too.

This started today, after the upgrading python2.7 packages to 2.7.14~rc1
in sid. Downgrading back to buster's 2.7.13-2 solves the problem.

I got the same error with Cython:

ImportError: /usr/lib/python2.7/dist-packages/Cython/Compiler/Code.x86_64-linux-gnu.so: undefined symbol: PyFPE_jbuf.  You should look at http://www.cython.org" 

It seems the following change in 2.7.14~rc1-1 broke the ABI:
  * Stop building the fpectl extension.

yes, that's intended. I'll add a break.  Are there other known packages besides
python-numpy?

Hi Mathias,

sorry, I don't see why uploading an unrelated package does actually
solve the problem? "Breaks" here does only prevent python3-numpy from
installed on sid, but it still allows python-numpy to be installed
together with the current Python 2.7?

This sounds a bit mystic to me.

Could you explain why this upload closes the bug?

Thank you very much

Ole

apprecommender uses python-numpy in its apprec-apt tool which is
called from an APT hook before apt installs or deinstalls any
packages. There it bails out like this on amd64:

Traceback (most recent call last):
  File "/usr/bin/apprec-apt", line 11, in <module>

This prevents any further installation or uninstallation of packages
with apt, aptitude, etc. without fiddling with hook configurations or
using dpkg to purge apprecommender.

sorry, but why the hell does apprecommender depend on python-numpy?

Which one do you mean?

Currently (from the tracker): Python 2.7 is still 2.7.14~rc1-2, and
Python 3.6 is still 3.6.2-3, both from yesterday, and both don't break
Cython. Cython also did not get an binNMU yet.

To me, this looks as it is still unresolved on both Python 2 and 3. I
just didn't want to create another issue since you do probably both in
the same step anyway.

Best regards

Ole

I'd even say "critical" instead of the previous "serious" since it
breaks unrelated packages like apt and aptitude. (But the "unrelated"
is discussable so I didn't raise the severity from serious.)

IMHO this issue (since there are breaks in the python packages) now
should be filed again against python-numpy and what else is affected.

Looks like python-scipy is also affected:

A complete list of all packages in unstable on amd64 that need rebuild
and Breaks is attached.

Additionally, Breaks are required for the following packages
that were already fixed in sid:
- cython
- cython3
- python-lxml
- python3-lxml

To avoid breaking testing, please keep these bugs open and RC until
all Breaks are in place.

Control: affects -1 + python-scipy python-fpylll

Cython autogenerated code uses the fpectl macros, so removing fpectl
breaks the ABI of probably all Cython modules, see [1] for a more
detailed explanation.

The last sagemath build [2] shows that at least also scipy and fpylll
are affected, with errors such as

ImportError:
/usr/lib/python2.7/dist-packages/scipy/linalg/_solve_toeplitz.arm-linux-gnueabihf.so:
undefined symbol: PyFPE_jbuf
ImportError:
/usr/lib/python2.7/dist-packages/fpylll/fplll/integer_matrix.arm-linux-gnueabihf.so:
undefined symbol: PyFPE_jbuf
ImportError: /usr/lib/python2.7/lib-dynload/_tkinter.so: undefined
symbol: PyFPE_jbuf, please install the python-tk package
