Upgrade: Singular 4.2.0, pysingular 0.9.7 #25993

jdemeyer · 2018-08-03T10:24:51Z

Tarball: see checksums.ini on the branch

Use make SAGE_SPKG="sage-spkg -o" singular-clean sagelib-clean build to automatically download and install.

"Critical" because it enables supporting newer versions of FLINT.

We use the Singular development branch (spielwiese) + PR Singular/Singular#1058 in order to build documentation. The tarball is made from https://github.com/mkoeppe/Singular/tree/Release-4-2-0-p1%2Bsage

Upstream: Fixed upstream, but not in a stable release.

Sigh. So I have to upgrade the group cohomology package earlier than I thought. I'll see what I can do (after grading some exam).

comment:6

The ticket description prominently tells that the group cohomology package is failing, but the title of the ticket is about upgrading Singular.

So, just to be sure about the topic of this ticket:

Is this ticket about upgrading Singular, which means that a new ticket for upgrading the group cohomology package needs to be created? If this is so, which of the tickets should depend on the other?
Is this ticket only about upgrading the group cohomology package? Looking at the commits, I suppose that this is not the case.

Replying to @jdemeyer:

It's not clear to me whether this is a Singular bug or a p_group_cohomology bug.

Most likely it is an API change.

jdemeyer · 2018-08-03T10:47:29Z

comment:8

This ticket is about upgrading Singular. If the p_group_cohomology package must be changed, ideally it should be done in a way which makes it compatible both with Singular 4.1.1p3 as well as earlier versions. In that case, the upgrade of p_group_cohomology can be done on a different ticket and #25993 should depend on that.

Concerning the commit history, only the last commit belongs to this ticket. The rest belongs to #24735 which is an upgrade of Singular to 4.1.1p2.

I see. Do you know if the breakage already happens in p2?

PS: I recently added a patch to Singular which backports a bugfix that is important to me. Is that bugfix in Singular-4.1.1?

I know that it does not occur. That's also a good reason to do the upgrade in two steps: first to 4.1.1p2 which works fine and then to 4.1.1p3 (or a later version) once p_group_cohomology is fixed.

Thank you! That sounds like a good plan. And do you know about the backported bug fix?

That's hard to say if you don't say which patch you mean. In any case, all patches which are currently (in Sage 8.3.rc3) applied to Singular are included in Singular 4.1.1p2.

Note that you said 4.1.1 but I guess you really care about 4.1.1p2 or 4.1.1p3. Despite what the version numbers suggest, experience shows that Singular adds non-trivial changes in such patch-releases.

It is backport_std.patch

I see. I thought that the "p something" patch level is Sage's addition of patches, not Singular's.

No, Sage's p levels have a dot. So you can have a Singular package version number like 4.1.1p2.p0 (where 4.1.1p2 comes from Singular upstream and .p0 from Sage). I know, it's confusing :-)

At least this time, it's not the fault of Sage but Singular :-)

I created #26001 to deal with the now needed upgrade of the group cohomology package. I suggest that I bae #26001 on top of #24735 (which by now is positively reviewed) and make the new ticket a dependency for the upgrade of Singular to version 4.1.1.p3.

simon-king-jena · 2018-08-05T11:19:55Z

Changed dependencies from #24735 to #24735 #26001

Replying to @kiwifb:

Question. Apart from the windows packaging stuff, is there any major change to take into account past 4.2.0_p1? As in, can a linux packager use 4.2.0_p1 and expect it to work?

Everything works fine with upstream 4.2.0_p1 and the sagelib changes in this ticket. Only caveat is that you need to install singular.idx manually.

Is singular.idx missing in the tarball?

Thanks, I thought that you could know already :) I already patch for singular.idx installation, nothing new there.

No, it is just not (no longer?) installed by make install.
