f894105d0d (tag: 8.5.beta4) Updated SageMath version to 8.5.beta4

[Steven Trogdon]

Something rather weird here. I'm unable to complete a pull of the latest 8.5.beta5 because of

Updating f894105d0d..b36eca1990

error: unable to unlink old 'docker/entrypoint.sh': Permission denied

Now entrypoint.sh is owned by root which I find strange

ls -al docker/entrypoint.sh

-rwxr-xr-x 1 root root 315 Aug 26 12:46 docker/entrypoint.sh

In fact in SAGE_ROOT there are numerous folders and a file owned by root

ls -al | grep 'root '

drwxr-xr-x  2 root     root   4096 Aug 26 12:46 .ci

drwxr-xr-x  2 root     root   4096 Aug 26 12:46 .circleci

drwxr-xr-x  3 root     root   4096 Aug 26 12:46 docker

Any idea as to what's with this? 8.5.beta4 was just fine.

I don't see anything like that here.

Did you maybe perform a "git pull" as root at some point?

[Steven Trogdon]

As far as I can recall 'git pull' was always done as a normal user. Note the timestamp on the folders, which predates 8.5.beta4. And this issue did not manifest itself then. But going forward, how to correct things?

Change to your SAGE_ROOT directory and run this as a normal user

$ sudo chown -v -R $(id -u):$(id -g) .

to set the owner and group of SAGE_ROOT (and recursively all
the included files and directories) to your user and your group.

[Steven Trogdon]

On my Gentoo changing the ownership was not sufficient. After changing the ownership I had to

git reset --hard HEAD

which revealed that

Updating f894105d0d..b36eca1990

error: The following untracked working tree files would be overwritten by merge:

To correct this:

git clean -f build/pkgs/barvinok/

git clean -f build/pkgs/isl/

git clean -f build/pkgs/lcalc/patches/

git clean -f build/pkgs/polylib/

and now 'git pull' is up to date. This is all very strange.

At some point you probably did *something* as root (and by "you" it
might not have even been an action you personally took, but maybe some
cron job you forgot about; who knows). But otherwise I don't think
there's any way that would have happened. This happens to me too
sometimes ¯\_(ツ)_/¯ Git repos don't store anything about uid/gid of
files (that would be disastrous); in fact IIRC the only information it
stores about file permissions is whether or not the executable bit
should be set.

On Ubuntu 18.04 running on Xeon E5-2623 + 16 GB RAM:

- python2:

  - incremental build (-j16) from 8.5.beta4 OK

  - all tests from ptestlong passed

 

- python3:

  - incremental build (-j16) from 8.5.beta4 OK

  - threejs viewer is now fully functional (at least as functional as with python2);

    for instance the S^2 notebook runs with python3 as well as with python2

On Ubuntu 16.04, the command

sage -t --all --optional=sage,optional,external

tests the following optional and external doctests:

Using --optional=bliss,cbc,ccache,cmake,dot2tex,external,gmpy2,lrslib,memlimit,mpir,normaliz,notedown,pandoc_attributes,pycosat,pynormaliz,python2,rst2ipynb,sage
External software detected for doctesting: ffmpeg,graphviz,gurobi,imagemagick,internet,latex,pandoc

and gives All tests passed except the following ones:

That’s interesting. I thought the failures in sage/databases/sql_db.py in sage-on-gentoo
were due to the use of a newer version of sqlite. But if you see it too that must be something
more subtle.

Could be caused by https://trac.sagemath.org/ticket/26702

[François Bissey]

This is definitely it. It introduced the doctests in question. I guess
I should have provided that extra info.

[Emmanuel Charpentier]

On Debian testing running onCore i5 + 8 GB RAM, I get three failures in one doctest :

----------------------------------------------------------------------

sage -t --long --warn-long 47.5 src/sage/interfaces/r.py  # 3 doctests failed

----------------------------------------------------------------------

 All three are dociuentation discordances in R (see attached file).

Probably a booboo, but I don't understand the root of the problem.

Probably due to https://trac.sagemath.org/ticket/26596, sorry. Was that a build using sage's build system (`make -j4 ptestlong` or similar) or the debian package?

[Timo Kaufmann]

I've created https://trac.sagemath.org/ticket/26791 for the rpy2 issue, please post there.

Built from a fresh clone of the develop branch on two macOS systems:

10.13.6 (2017 iMac Pro, 18-core Xeon W) - no problems with build and the testing (‘ptestlong’) yielded these (familiar) failures:

sage -t --long --warn-long 60.2 src/sage/combinat/designs/ext_rep.py # Killed due to abort
sage -t --long --warn-long 60.2 src/sage/doctest/external.py # Killed due to abort
sage -t --long --warn-long 60.2 src/sage/libs/singular/polynomial.pyx # 1 doctest failed

Logs available if needed.

10.11.6 (mid-2015 MBP, Quad-core Core i7) - no problems with build, and all tests passed.

I just created

https://trac.sagemath.org/ticket/26920 

for the issue with sql_db.py since it is still a problem with 8.5.rc0.
