Started from a clean copy of 7.3.beta8 develop
and pulled in changes for this ticket. Ran make
and got this error:
The following package(s) may have failed to build (not necessarily during this run of 'make all'): * package: sagelib7.3.beta5 log file: /Users/Masson/Downloads/GitHub/sage/logs/pkgs/sagelib7.3.beta5.log build directory: /Users/Masson/Downloads/GitHub/sage/local/var/tmp/sage/build/sagelib7.3.beta5
Ran make
again on develop
with no problem.

Any update on the 7.3.beta5 error message? Something on my end or yours?

Replying to paulmasson:
Started from a clean copy of 7.3.beta8
develop
and pulled in changes for this ticket.
How did you "pull in" the changes? BTW, if you do git trac checkout 21034
you will always get the Sage version of the branch in 21034, regardless of your develop. Also a hint: make start
will skip building the expensive step of building the docs.
You should also download the pynac tarball and copy it into upstream/
before making.
comment:8 Changed 4 years ago by
Originally did git trac pull 21034
. This time did git trach checkout 21034
and getting same error. Then also copied pynac tarball to upstream
folder and still getting error. Last bit not building is this:

Can't review until it builds completely.
comment:9 Changed 4 years ago by
In comment:5 you write about starting from beta8 but the output shows beta5. Can you please confirm that beta8 develop compiles cleanly? I'm asking because on the sagedevel there are several reports about problems of beta8 on MacOS.

7.3.beta8 develop compiles cleanly on Mac OS X El Capitan

Branch pushed to git repo; I updated commit sha1. New commits:
0eb21db  Merge branch 'develop' into t/21034/upgrade_to_pynac_0_6_8

comment:12 Changed 4 years ago by
beta9 is now merged into the branch and has all recent MacOS fixes. Please either do git trac pull 21034
in your local copy of this branch, or delete your local copy of this branch and do a git trac checkout 21034
. And try again.
comment:13 Changed 4 years ago by
Sorry Ralf, but still getting the error. Curiously even though it references "sagelib7.3.beta5.log" this file hasn't been modified building either beta8 or beta9.
Before you ask, 7.3.beta9 develop also compiles cleanly on Mac OS X El Capitan.
Looking back to the pynac 0.6.7 upgrade, there is a comment from Travis that looks relevant. This prompted me to see which beta included 0.6.7 and sure enough it was beta5.
I'll be the first to admit knowing nothing about building tarballs, but are you sure there isn't a problem there? The tarball for 0.6.8 isn't downloading automatically to the upstream
folder.
comment:14 Changed 4 years ago by
Paul, Sage cannot download pynac0.6.8 because this is only possible after this ticket is merged. As a reviewer you need to download manually and copy it into upstream. Note however that the tarball might be deleted again by Sage at some time. So always make sure it's there before compiling this branch.
comment:15 Changed 4 years ago by
This time I downloaded the tarball to upstream
, deleted the local branch, did git trac checkout 21034
, confirmed the tarball was in place and ran make
. Unfortunately, same error. Tarball still there after make
errors out. What now?
comment:16 Changed 4 years ago by
In an effort to move this forward, I did make distclean
followed by make
. The latter fails for both master
and develop
, so there are Mac issues at play. Will report on sagedevel.
comment:17 Changed 3 years ago by
Not a Mac problem after all. I accidentally merged #21006 some time ago which left behind an empty package folder named "prompt_toolkit". Any package following it alphabetically was ignored, including pynac.
comment:18 Changed 3 years ago by
Finally built this ticket! Some preliminary questions:
1) The second plot in #18368 still throws an error. Have you modified the behavior of the zeta function in Pynac or just the polylog? If the latter, the doctest you included doesn't appear to address the problem with the zeta function on that ticket.
2) Numerical evaluation of the beta function looks good, so that fixes #15196. I have noticed however that evaluating the beta function at poles returns NaN
rather than unsigned infinity. Is this something that needs to be addressed in Sage or Pynac?
3) The description of #20888 makes it sound like an existing LaTeX string in Pynac overrides one in Sage. Is that correct? If so, shouldn't entries in Sage always take precedence?
4) This ticket doesn't appear to change anything for #20455. Does that ticket need to be addressed in Sage using behavior now available from Pynac?
Will do more testing tomorrow. Thanks for putting up with my build issue.
comment:19 Changed 3 years ago by
 Description modified (diff)
1) Yes, only part of #18368 is fixed, 2) the infinity problem has to be addressed in Sage and it's the same problem as #19439 so it should go in that ticket, 3) Yes, and this is only one example where Pynac code overrides Sage code (I don't think this is a problem in principle), 4) Good Question, in the process of implementation I had to revise my opinion, let's discuss that in #20455.

Doctests pass. Documentation builds. Outstanding issues will be addressed on indicated tickets.
Good to go.
