Upgrade to Singular-4.x.x #17254

Closed jdemeyer closed 8 years ago

jdemeyer commented 10 years ago

Lots of stuff has changed in Singular 4. This is a big update.

Build system completely changed, and a lot of internal stuff.

Original upstream tarball at www.mathematik.uni-kl.de/ftp/pub/Math/Singular/SOURCES/4-0-3/: singular-4.0.3p3 dot tar dot gz

Modified tarball made with spkg-src at:

This corresponds to commit a070b84d whose message tells 4.0.3p3 and on which this branch was based:

You can also make your own tarball based on this commit or another one with

env SINGULAR_GIT_COMMIT=a070b84d ./sage --sh build/pkgs/singular/spkg-src
./sage --package fix-checksum singular

This script is loosely based on the make_tar.sh script from upstream.

Depends on #17635

Yeah, the update is non trivial, that's a reason to get #17184 (and so #16882) inbetween.

Replying to @jpflori:

Yeah, the update is non trivial

I wonder if we even have a Sage developer who is familiar enough with Singular to do this (for the record: not me, I know nothing about Singular).

that's a reason to get #17184 (and so #16882) inbetween.

Of course, I'm not arguing with that.

Maybe Burcin would do... IIRC the update was proposed as a GSoC project.

Q: where to get the singular tarball for this commit? I get a failure at 

Trying to download http://www.sagemath.org/packages/upstream/singular/singular-4.0.1p1.tar.bz2

2.

Update to Singular 4.0.1

Maybe Burcin would do...

Could the update to 4.0.1. be done by at least two or three persons to spread the knownledge about Singular internals?

You have to put a tarball repackaged by the spkg-src script in the upstream folder directly. Once the ticket is merged, the tarball will be put on the official mirror and could be downloaded automatically but not at the moment.

I've put a repackaged tarball at:

(I'm not sure the checksums will the same as what Jeroen branch expect, run ./sage -sh sage-fix-pkg-checksums after you have downloaded the tarball to fix this.)

And I'd be happy to work on the upgrade and learn more about Singular's internals, but please also review the "easy" #17184 (where I've already learnt some stuff) firsT.

Singular 4.0.1. compiles now in sage but sage does not yet - I just pushed a branch 'u/jakobkroeker/ticket/17254'. You have to correct the 'singular-4.0.1p1.tar.bz2' tarball to get it work ( the 'm4' folder is missing).

For the moment I removed some patches; we probably will have to adjust them later on. For example there is meanwhile no such thing like 'lomalloc_ndebug' so if we want to disable some debug functionality or output for omalloc we have to do that by passing appropriate flags to omalloc/configure, e,g '--enable-optimizationflags --disable-debug --without-debug' ?

Also I disabled the currently broken '--enable-debugoutput' configure flag for the standalone 'factory' and informed Oleksander Motsak about the issue.

Could someone of you take care of the sage compile errors and figure out what is going wrong and/or ask for help in the Singular forum? I can't do that easily, because within the Singular-team I'm out-of-favor because I constantly criticise their software and thus I will likely get little or no support.

Confirm; cannot reproduce the issue. So likely I didn't use the recent tarball, or I screwed something up.

I'm guilty ;-)

comment:22

After a little more tweaking and temporarily disabling the extension fields/rings, I was able to build some parts of sage with Singular 4.0.1 on a 'fc18 system' and then.. sage crashes at start! That happens because I didn't update ring creation right - I only recently discovered examples at './libpolys/tests/rings_test.h'. And some sage packages create common rings at loading time.

remaining riddles:

See branch u/jakobkroeker/ticket/17254 and some notes at https://github.com/jakobkroeker/jk_test_sage/issues/13

If a build get stuck before errors described above, then maybe a 'make distclean' is necessary. And of course, the Singular tarball http://boxen.math.washington.edu/home/jdemeyer/spkg/singular-4.0.1p1.tar.bz2 is required.

Any help appreciated.

I'm busy and can't work on the ticket currently and expect to have time for the ticket at end of June, not earlier...

with the state as is, sage should build and start (using the Singular tarball from above), but extension fields and transcendental fields are not functional yet and also a cython Singular-interface cleanup has to be done.

I'm at SD64.25 and am willing to work on this, but I'll need some hand-holding since I haven't worked on a package like this before. Do you have any suggestions for ways to test extension and transcendental fields?

I just applied this to 6.4.1 and encountered the message,

Any ideas what causes this?

I haven't looked yet at the new singular 4.0.x but the first port of call would be to check if the header is indeed installed in $SAGE_LOCAL/include.

Shortly after, that installation of Sage fell completely apart (not sure why) so now I'm working on Sage-6.7.

On 6.7, git identifies some issues with merging in singular.pyx and ring.pyx, but they're fairly clear to fix, so I did. (Unless they weren't easy.) Things went much further this time, until I encountered this error:
