Re: [sage-devel] Trouble building cython

[Zachary Scherr]

I need to sign off for the night, but the numpy error is definitely related 
to gfortran.  If you have gcc installed via homebrew then it should come 
with the latest version of gfortran.  You can see from your config.log file 
that gfortran is not found:

configure:7281: checking for gfortran
configure:7311: result: no

and other standard homebrew packages are not found, like openblas:

configure:12171: checking BLAS library
configure:12190: result: openblas
configure:12239: checking whether any of gfortran is installed as or will 
be installed as SPKG
configure:12243: result: yes; install openblas as well
configure:13540: no suitable system package found for SPKG openblas

are you aware if you have gcc and openblas installed via homebrew? I also 
see that you didn't run "source .homebrew-build-env" before running 
./configure since I don't see certain items on your path.  If you go to the 
sage installation guide 
at 
https://doc.sagemath.org/html/en/installation/source.html#macos-recommended-installation
 
you can see a list of homebrew packages you might want to have before 
installing sage.  I think if you get everything in working order with 
homebrew then you shouldn't have any issues installing sage.  Here is my 
best suggestion as to what to try:

- fix all "brew doctor" warnings.  This might not be necessary, but I get 
worried when I see so many warnings.  You can probably just delete all the 
suggested files and you should be fine.

- install all the recommended homebrew packages.  If any are already 
installed then maybe try "brew reinstall" to make sure it is installed 
properly.  If you think you have homebrew gcc installed then you should be 
able to do "which gfortran" and "gfortran --version".  That should 
hopefully show you that you have gfortran 10.2.0_3.

- in your sage folder under the develop branch you should run the commands 
I mentioned, and don't skip out on "source .homebrew-build-env":

>> make distclean
>> ./bootstrap
>> source .homebrew-build-env
>> ./configure

Before running "make -j4 build" you can look at config.log and make sure 
that it picked up all of the relevant homebrew packages.

Re: [sage-devel] Trouble building cython

[Zachary Scherr]

At some point you should deal with those warnings, but I don't think that 
is what is causing your problems (although they are probably symptomatic of 
other possible issues).  

The config.log file you posted earlier is picking up a lot of packages that 
were built by sage and not from homebrew.  Do you have the config.log file 
that you got after running make distclean?

Re: [sage-devel] Trouble building cython

[Zachary Scherr]

In your original config.log, it looked like sage was picking up its own 
fortran:

configure:11991: gfortran has already been installed by SageMath
configure:39396: result: gfortran-9.2.0: 
 already installed as an SPKG

The current version of gfortran from homebrew is 10.2.0 version 3

Copyright (C) 2020 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

./configure should be picking up homebrew's gfortran (installed with gcc), 
and it seems from your config.log file that you do have homebrew and 
therefore you should have the most recent gfortran.
Do you have the newest config.log file from after running make distclean? 
You may also want to try running

brew doctor

to see if there is something wrong with your homebrew.

 So I tried your second suggestion and it seems to be working so far,
 but it is still compiling.

Another thing that a downstream package can do is declare an 
"install_requires" on the Sage library, specifying a supported range of 
versions. Then we should be able to use the dependency resolution by pip to 
be sure to install a compatible version.

Note https://trac.sagemath.org/ticket/30912 updates the metadata of the 
Sage library, defining the distribution name "sagemath-standard". (Another 
distribution that could be used for versioning is "sage_conf".)

Also note the pip dependency resolver has just changed with the update to 
pip 20.3.3 in #30589 (see 
https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020).

I think that if we do not provide explicit version of downstream
packages, we are going to run into troubles, as we can not expect users
to use latest Sagemath version when they install some downstream
package.

To take the previous example:

https://github.com/mkauers/ore_algebra/commit/8c678f9c70aee8df211c04211dd2f7e230a4770f

without versionning on our side, if a user tries to install ore_algebra
after 7 November 2017 while using 8.0, they would get import errors.

Note also that this downstream change was done during the preparation of
8.1 (that was released on 7 December 2017), so even up-to-date
non-developer users would have been running 8.0 at that time and
therefore get errors.

I do not see how having ore_algebra in PyPI would fix the issue of not
providing downstream versions.

Re: [sage-devel] Trouble building cython

[Zachary Scherr]

yea, something seems messed up.  For example, the numpy problem was fixed 
on beta 6 and should still be fixed in beta 7.  It looks like somehow you 
have old files hanging around which are causing problems.  Hopefully make 
distclean will clean everything and let you start fresh.

 Probably the thing to try would be:

 make distclean

 and then you can build from scratch via:

 ./bootstrap
 source .homebrew-build-env
 ./configure
 make -j4 build

 But if you want to try cleaning wheel first before starting from 
 scratch, you could just try

 make wheel-clean
 make -j4 build

 but it might be better to clean everything and start from scratch.

I must have typed it wrong. The second option you gave failed on numpy, but

I meant "requirements.txt" actually.

That's right, this is an important distinction.

As Vincent has pointed out, we currently do not use version constraints for 
these (downstream) user packages. 

I think it should be the responsibility of the downstream package to define 
a versioning policy - define when they plan to drop support for a 
particular Sage version. 
Then we can use an appropriate version constraint in the 
"install-requires.txt" file for this package in build/pkgs.

Another question: what happens if at the end of a Sage release cycle,

Setting type to "experimental" would be good enough, I think. This already 
issues a scary warning.

I would suggest that we remove them from that page when 9.3 is released.

Re: [sage-devel] Trouble building cython

Are you sure you typed it correctly? Maybe try running

./bootstrap

to make sure that the make targets are in order.

Re: [sage-devel] Trouble building cython

I tried make distclean and got an error “make: *** No rule to make target
‘distclean’. Stop.”

So I tried your second suggestion and it seems to be working so far, but it
is still compiling.

Re: [sage-devel] Trouble building cython

[Zachary Scherr]

Probably the thing to try would be:

make distclean

and then you can build from scratch via:

./bootstrap
source .homebrew-build-env
./configure
make -j4 build

But if you want to try cleaning wheel first before starting from scratch, 
you could just try

make wheel-clean
make -j4 build

but it might be better to clean everything and start from scratch.

Re: [sage-devel] Trouble building cython

[Trevor Karn]

I do not see pep425tags.py in that directory.

trevorkarn@Trevors-MacBook-Air sage % cd
/Users/trevorkarn/Applications/sage/local/lib/python3.9/site-packages/wheel/

trevorkarn@Trevors-MacBook-Air wheel % ls

__init__.py __pycache__ cli metadata.py util.py wheelfile.py

__main__.py bdist_wheel.py macosx_libfile.py pkginfo.py vendored

Is there a way to clean the build environment?

Trevor Karn

Re: [sage-devel] Trouble building cython

[Dima Pasechnik]

the only explanation for pep425tags.py would be an unclean build
environment - e.g. weird env vars set, or strange stuff in PATH.

Re: [sage-devel] Trouble building cython

[Zachary Scherr]

I really don't understand.  The Cython log file shows that the problem is in

/Users/trevorkarn/Applications/sage/local/lib/python3.9/site-packages/wheel/pep425tags.py

I could be mistaken, but I don't think pep425tags.py has been a part of the 
wheel package for a while now.  Certainly when I looked at wheel on my sage 
there was no such file.

Can you go to your 
"/Users/trevorkarn/Applications/sage/local/lib/python3.9/site-packages/wheel/" 
directory and take a look at __init__.py.  Does the version say 0.36.2?

Re: [sage-devel] Trouble building cython

[Trevor Karn]

I also have this. Is there any reason it might be calling python instead of
python3?

trevorkarn@Trevors-MacBook-Air sage % python3 --version

Python 3.9.1

trevorkarn@Trevors-MacBook-Air sage % python --version

Python 2.7.16

[sage-devel] Re: [GSoC Mentors Announce] Now Accepting GSoC 2021 Mentoring Organization Applications until Feb 19

[mmarco]

I have participated as mentor other years... but this year I just don't 
think I have the needed energy.

I think Harald's proposal to pass this year and reconsider the next one 
makes sense (sadly).

Could it be that you need to update your Homebrew (?) python3 package?
What version do you have now?
E.g. on a box where the latest Sage builds I have

sorry, I was not clear. What I meant to say that it appears to be a
well-known issue in the Python@macOS universe,
and lately all seems to be OK with Sage.

To figure out exactly goes wrong in your case, we need to know where
Python3 used in Sage is coming from.
Please post the top-level config.log

Thanks for sending that link. I am confused though, because it says a fix
was issued. Does that mean it should work now?

And yes, I am on the most recent develop branch

Re: [sage-devel] Re: Help needed with adding user packages as optional/experimental packages

[Vincent Delecroix]

For most of the packages, there is no explicit version tracking. On
the current rather small list only ore_algebra has an explicit
reference to a commit in requirements.txt

$ cat admcycles/requirements.txt
admcycles

$ cat surface_dynamics/requirements.txt
surface_dynamics

$ cat ore_algebra/requirements.txt
git+https://github.com/mkauers/ore_algebra@6826ac49b4cdf66a563449aced21a2fd1fd085c9#egg=ore_algebra

If instead ore_algebra would properly release on PyPI, the
sage side of things would be simpler.

Best
Vincent

PS: still there is the issue of "old" SageMath versions that might
not be compatible with "recent" package versions. The only mechanism
is to tight a single version of a package to a SageMath version as it
was done with ore_algebra. The latter is quite restrictive given that
packges might evolve between two sage releases.

We should notice that, contrary to other packages, those packages should
be considered as downstream (not upstream), and this should be reflected
in our release process.

Indeed, their code get adapted after Sage changes, see e.g. (randomly
chosen examples):

https://github.com/mkauers/ore_algebra/commit/2d71b50ebad81e62432482facfe3f78cc4961c4f
https://github.com/mkauers/ore_algebra/commit/8c678f9c70aee8df211c04211dd2f7e230a4770f

For upstream packages (especially important ones), they should usually
be merged in the beginning of a new release (on beta[n] with small n),
so that incompatibilities could be reported and fixed before the
official release.

In the current case, it should be the opposite, after downstream adapted
their code to our changes, so that those packages are not broken for the
official release.

Hence, there should be a way to update the versions of such packages
during beta[-1] (the one before rc0), at least those packages should be
tagged "downstream" somewhere (e.g.  whithin SPKG.rst file or whatever),
so that someone could have a look before the rc.

While our naming of development releases is pretty poor (beta or rc), we
should perhaps indicate somewhere which intervals are reserved for
backward-incompatible changes, and so on.

Another question: what happens if at the end of a Sage release cycle,
the downstream package is still broken ? Shall we remove the package
from build/pkgs ? Shall we add a temporary patch within the spkg
directory ? Or add a "broken" keyword for the "type" file ?

Re: [sage-devel] possible bug: kernel of ring homomorphism

[Akos M]

It seems that unfortunately the problem persists for multivariate rings as 
well:

A. = QQ[]
B. = QQ[]
H = B.quotient(B.ideal([B.2]))
f = A.hom([H.0, H.1], H)
f
f.kernel()

Ring morphism: 
 From: Multivariate Polynomial Ring in t, u over Rational Field 
 To: Quotient of Multivariate Polynomial Ring in x, y, z over Rational 
Field by the ideal (z) 
 Defn: t |--> xbar 
   u |--> ybar 
Ideal (-t, -u, 0) of Multivariate Polynomial Ring in t, u over Rational 
Field

I have the impression that the fact that the ring homomorphism is to a 
quotient ring introduces the error, but that's just a wild guess.

Re: [sage-devel] possible bug: kernel of ring homomorphism

A wild guess would be that it's due to univariate and multivariate
rings handled by different backends in Sage, one sees this kinds of
corner cases errors.

Re: [sage-devel] possible bug: kernel of ring homomorphism

It looks like a bug to me.   f.kernel() expands to
f._inverse_image_ideal(f.codomain().zero_ideal()) and
f.codomain().zero_ideal() looks OK so the problem must be in the
inverse image.  The author is apparently Simon King (2011).  Simon,

[sage-devel] possible bug: kernel of ring homomorphism

[Akos M]

Hi, 

I'm not sure whether this is a bug or not, but the kernel of a ring 
homomorphism to a quotient ring gives unexpected results:

A. = QQ[] 
B. = QQ[] 
H = B.quotient(B.ideal([B.1])) 
f = A.hom([H.0], H) 
f 
f.kernel()

outputs:
Ring morphism: From: Univariate Polynomial Ring in t over Rational Field 
To: Quotient of Multivariate Polynomial Ring in x, y over Rational Field by 
the ideal (y) Defn: t |--> xbar 
Principal ideal (t) of Univariate Polynomial Ring in t over Rational Field

whereas the kernel of f:A[t]->B[x,y]->B[x,y]/(y), for f(t)=x should be (0).

Is this a bug?
Thanks,
Akos

 Hi John,
 IIRC, a dict has its keys automatically sorted in the output. However, 
 if the dict is inside of another object, then no sorting is done. So if it 
 is a simple dict with a total ordering on the keys, then you can simply 
 put the output. You can also run sorted() on the items if they dicts are 
 inside of other objects. Otherwise you might be better off testing the 
 individual aspects you want, such as specific values are correct. Could 
 you point to which ticket and/or test you want?
