Any chance someone can give me review on the following tickets:

https://trac.sagemath.org/ticket/21233
https://trac.sagemath.org/ticket/23097

?

The first fixes the one consistently failing test on Cygwin. Florent
reviewed it once a long time ago and had some comments, but I believe
I've addressed his comments (I could be wrong there but I think the
code is fine as is).

The second fixes a bug that doesn't show up in any tests, but can
still lead to severe disk cluttering over time.

Thanks,
Erik

On Debian testing, running on Core i7 + 16 GB RAM, ptestlon passed with two transient failures :

----------------------------------------------------------------------
sage -t --long src/sage/plot/plot.py  # Timed out after testing finished
sage -t --long src/sage/homology/simplicial_complex.py  # 1 doctest failed
----------------------------------------------------------------------

Both passed when ran standalone.

I'll try to do that tonight (probably overnight, since I've only a (small) VM to test that on...).

On Ubuntu 16.04 x86_64 Xeon E5-2623 + 16 GB RAM, from a fresh git clone + pull develop, parallel (-j16) build OK and make ptestlong passed.

Eric.

[Emmanuel Charpentier]

Done. IO've given positive review to these two tickets, as well as to two tickets (#21399, #23339) pointed in the Wiki with long-standing needs_review status.

Is libvpx a new Sage dependency? For me building rc0 fails on Fedora 25 with

[dochtml]   File "sage/matrix/matrix_mod2_dense.pxd", line 4, in init sage.matrix.matrix_integer_dense (build/cythonized/sage/matrix/matrix_integer_dense.c:55469)

[dochtml] ImportError: libvpx.so.2: cannot open shared object file: No such file or directory

Makefile:985: recipe for target 'doc-html' failed

make[2]: *** [doc-html] Error 1

See http://users.ox.ac.uk/~coml0531/sage/install.log.txt

for the complete log.

[François Bissey]

HA! No it is not. You could do a search on sage-devel where it has been raised
before. In short libgd found libvpx and build itself with support for vpx.
Then libvpx has been upgraded in your distro…
https://groups.google.com/forum/#!msg/sage-devel/0-GMsiyK8yw/84uN8q3GAgAJ;context-place=forum/sage-devel
https://groups.google.com/forum/#!searchin/sage-release/libvpx%7Csort:relevance/sage-release/v6exlZDkXGc/DLctGMW7NDsJ
for example. There are a few more if you search.

[Dima Pasechnik]

ah, OK, thanks,

already pulled the trigger of distclean though :-)

[Sébastien Labbé]

On Ubuntu 16.04, make ptestlong finishes with two doctest failures that were already reported on this mailing list. Both doctests pass when run separately.

----------------------------------------------------------------------
sage -t --long --warn-long 61.4 src/sage/homology/simplicial_complex.py  # 1 doctest failed
sage -t --long --warn-long 61.4 src/sage/sat/boolean_polynomials.py  # 1 doctest failed
----------------------------------------------------------------------

See
https://trac.sagemath.org/ticket/15585
for the first one.

I created
https://trac.sagemath.org/ticket/23351
for the second one.

Which is possibly fixed by https://trac.sagemath.org/ticket/22462 (needs
review).

[Emmanuel Charpentier]

According to the patchbots, Trac#22462 fails to build. What does that mean exactly ?

[Ralf Stephan]

ImportError: cannot import name ContainChildren

[Emmanuel Charpentier]

Thkis I understood. But to me, it meas that, as proposed, the patch can't compile, and therefore, needs work. But I'm not sure of this interpretation (I do not (yet) understand) what the patchbot is supposed to do ; therefore, I do not jnow if this is a patchbot error or a real problem with the patch).

It's not a patchbot problem if you can reproduce it. Just check out the branch, start Sage.

Built from a git checkout. No problems (macOS 10.11.6. Quad-core Core i7). Testing (‘ptestlong’):
- first run yielded one failure
sage -t --long --warn-long 101.6 src/sage/libs/gap/assigned_names.py timed out
- reran the build (essentially just the testing) and all tests passed.
