After (1) Building a fresh 4.7.alpha5 from scratch, (2) installing the spkg lined here with "sage -f", (3) applying the patch here to the sage library and (4) running "sage -b", I find that the Sage build will not start up properly:
ImportError Traceback (most recent call last) ... /home/jec/sage-4.7.alpha5.11130/local/lib/python2.6/site-packages/sage/misc/functional.py in <module>() 36 37 ---> 38 from sage.rings.complex_double import CDF 39 from sage.rings.real_double import RDF, RealDoubleElement 40 /home/jec/sage-4.7.alpha5.11130/local/bin/gen.pxd in init sage.rings.complex_double (sage/rings/complex_double.c:15178)() ImportError: /home/jec/sage-4.7.alpha5.11130/local/lib/python2.6/site-packages/sage/libs/pari/gen.so: undefined symbol: defaultOut Error importing ipy_profile_sage - perhaps you should run %upgrade?

so I cannot test anything.

I am currently testing this. To avoid duplication of effort, I'll fix things I find in the elliptic_curves directory only.
Sounds good, I will look at everything else.
comment:23 Changed 9 years ago by
I added a patch which fixes the doctest failures in sage/rings/polynomial/polynomial_quotient_ring.py . In all cases the new output was equivalent to the old.
There are now just some failures in sage/schemes/elliptic_curves/ell_rational_field.py (2 doctests failed) and sage/schemes/elliptic_curves/ell_number_field.py (1 doctests failed).
comment:24 Changed 9 years ago by
- Reviewers set to John Cremona
- Status changed from needs_work to needs_review
ell_rational_field.py: only one failure, looks completely trivial but will be left until #11005 to be fixed.
ell_number_field.py: one failure, even more trivial: the final output is exactly the same as it was but the verbose output is a little different, so this can be easily cleaned up at #11005.
As far as I am concerned this needs *no more work* on this ticket, but I'll delay marking it positive review until the same is possible at #11005. Still, it certainly gets "needs review" on that basis.

That's all I have time for today, so I hope things look similar on the other 32-bit system being tested.

I have added a new patch (which affects 4 files in sage/rings) after which all doctests pass on both 32- and 64-bit, apart from the simon-related ones.
That means that it is time to check #11005 on top of all this.

A reasonable assumption, but...for a while now I have used Sage's Pari and NTL builds rather than building them myself independently, so I cannot yet confirm. (However, eclib's use of Pari is minimal, it's only for integer factorization.)
I am also preparing a new version of eclib, so I will combine these two tasks, though I don't have any time for this this week.

So is the "Needs work" just because this ticket is dependent on #11005? I am planning to look now at the doctest failures relating to the Simon scripts and fix them, so that this ticket can then be closed, and the additional work needed on #11005 can depend on this.

That's precisely what I proposed.
OK, so that's what I am working on doing. Patch up shortly. However, I ran into something awkward: the script ellQ.gp in data/extcode/pari/simon crashed randomly in the function ellredgen (using this new pari version). I saw that the offending lines had been changed in the newer ellQ.gp as found in #11005, so I made the same changes. This sorts the problem, but it means that for this ticket to be finished we need to also make a small patch to extcode. Any problems with that?

Well I considered that I had reviewed (positively) everything except my last patch fixing the Simon doctests so that's the only thing left needing a review (from you perhaps, especially as you made some extra fixes for 32/64 bit issues).

Starting with a clean 4.7.1.rc1 (I think) I successfully applied both spkgs (using SAGE_CHECK=yes) and 5 patches to sagelib and 1 to data/extcode, and did sage -ba.
Sage now starts up OK but I'm having a lot of problems with any more testing. For example, moving into devel/sage and doing "../../sage -tp 20 ./sage" results in very many errors, looks like in every file, like this:
Traceback (most recent call last): File "/home/jec/.sage//tmp/facade_sets.py", line 2, in <module> from sage.all_cmdline import *; File "/home/jec/sage-4.7.1.rc1/local/lib/python/site-packages/sage/all_cmdline.py", line 24, in <module> raise ValueError, msg ValueError: Attempted relative import in non-package
I checked (using bash's history) that I had remembered to hg qpush each patch.
Does this make any sense? I suppose I could rebuild 4.7.1.rc1 from scratch.

The latter type I've already seen while trying to ./sage -f the previous Pari (2.4.3.alpha.px), but I haven't seen the first kind or second kind before. Something similar to the third one I've seen in some build notes of William's as being a problem with gmp being -I'ed before some other include directories, and the first one looks like one of these "double inclusion" problems.

Looks as if you're somehow^{TM} mixing the old PARI (at least the static library libpari.a

I have no idea why this happens. Can you try to build http://boxen.math.washington.edu/home/jdemeyer/release/sage-4.7.1.rc1-pari-2.5.0/sage-4.7.1.rc1-pari-2.5.0.tar from scratch and test that? If this works, probably you did something wrong in merging the spkgs/patches.

Interestingly, it works fine from scratch (building)! Sorry for the noise, if noise it was.
Is there something about Pari that you shouldn't build it twice in the same location? I notice that it removes and replaces various things in $SAGE_LOCAL
before it's all done, so maybe that could happen. In principle, one should be able to ./sage -f
a new version, have something break, and then be able to ./sage -f
the original version and have everything fine. Or not even HAVE to ./sage -f
the original version. The fact that this doesn't work is not good - shouldn't we only copy things over/delete things after the build has successfully completed?

Well the gp executable is linked against libpari and there is a danger that the old one will be used when linking if you are not careful enough. It should be ok in principle but the precaution of removing previous libpari is a good one.

before it's all done, so maybe that could happen.
The PARI spkg doesn't delete anything of previous installs in advance. (The .alpha
.p5
though had a bug which caused the install script not to exit with an error if make
failed. Also, on Cygwin make -k
("keep going") was used, but that shouldn't matter here, and has been removed in the 2.5.0 spkgs.)
In principle, one should be able to
./sage -f
a new version, have something break, and then be able to./sage -f
the original version and have everything fine. Or not even HAVE to./sage -f
the original version.
Both should^{TM} be possible, at least unless the build succeeds but the actual installation fails at some point, in which case the former method should still work.
The fact that this doesn't work is not good - shouldn't we only copy things over/delete things after the build has successfully completed?
That's what we do.
Well the gp executable is linked against libpari and there is a danger that the old one will be used when linking if you are not careful enough. It should be ok in principle but the precaution of removing previous libpari is a good one.
Things are a little different on Cygwin, since the Sage Cygwin developers ;-) copy the DLL also to $SAGE_LOCAL/bin
such that gp
will find its shared library also there.
PARI (2.4.3) prepends its build path (with -L
) when using -lpari
, except for when it links gp
[-2.4
] "in place", but this happens after the new shared library (.so*
, *.dll
on Cygwin) has been copied and new symbolic links have been created. The new static library is built and copied later though, but that shouldn't matter unless gp
is statically linked on Cygwin, which shouldn't be the case.
If despite that something weird happens, this is IMHO limited to Cygwin; you may attach your spkg install logs ($SAGE_ROOT/spkg/logs/pari-*.log
) such that we can check this.
We also didn't have problems with upgrading to 2.4.3 btw., except that initially some dependencies of Sage's extension modules were missing such that those didn't get rebuilt in the first place (and used the old ones with a different version they had been linked to earlier).

ValueError?: Attempted relative import in non-package
I have no idea why this happens. Can you try to build http://boxen.math.washington.edu/home/jdemeyer/release/sage-4.7.1.rc1-pari-2.5.0/sage-4.7.1.rc1-pari-2.5.0.tar from scratch and test that? If this works, probably you did something wrong in merging the spkgs/patches.
I'm downloading that now and will report back.

Built with no problems. But "make ptestlong" failed 100% just as before. The install and ptestlong logs are at http://www.warwick.ac.uk/staff/J.E.Cremona/ptestlong.log and http://www.warwick.ac.uk/staff/J.E.Cremona/install.log

The strange thing is that the traceback you get seems totally unrelated to PARI.

I know, it is mad. After this happened with my 4.7.1.rc1 yesterday I wanted to review something else, so I did that using my 4.7.1.rc0 which was untouched, and found the exact same errors arising whenever I tried "sage -t". This is on a machine I have been using for Sage development and testing for a year, on which no-one but me installs stuff.
Here are some possibly relevant environment variables (not changed recently):
SAGE_PARALLEL_SPKG_BUILD=yes SHELL=/bin/bash LD_LIBRARY_PATH=:/usr/local/lib:/home/jec/sage-current/local/lib
The reason for the LD_LIBRARY_PATH is that I use Sage's built libraries for other work (libntl and libpari); but seeting that to just /usr/local/lib made no difference anyway.

Same happens with just ./sage -t ...
or make test[long]
, i.e. non-parallel?
We had strange errors with ptest[long]
or ./sage -tp N ...
when SAGE_PATH
was set (even to the empty string).

That is not set:
jec@fermat%env | grep SAGE SAGE_PARALLEL_SPKG_BUILD=yes
make testlong was no better, neither is testing a single file (e.g. ./sage -t devel/sage/sage/rings/infinity.py). Sage does start up properly.
Looking at the actual error message (why not?) I see that it complains that the line
from sage.all_cmdline import *;
which is presumably included in the testing framework, causes sage.all_cmdline.py to be imported, and then in line 24 of that file the line 24:
raise ValueError, msg
raises the error, with the message coming from a few lines above where there is a try/except block containing
from sage.all import * from sage.calculus.predefined import x preparser(on=True)
and this is causing some kind of circular import.
Anyway, by 4.7 build which I have been using for weeks, and which passed all the tests when I built it, now gives rise to exactly the same problem. So this is nothing to do with any of the code on this ticket, but instead something weird that has happened with my Sage installations.
Here's an idea: I have several background jobs running sage; is it possible that this is the problem? They will also be writing to ~/.sage. I'll try again when they have finished.

Well, easily checked:
$ env DOT_SAGE=/tmp ./sage -t devel/sage/sage/rings/infinity.py

considering the amount of broken test you have, does sage even start properly without wanting to test it.

Yes, all the version I have start and run fine, but none of them cab run any tests. I have never seen this before, but it's something to do with my setup (and several sage jobs running in the background on the same machine) so we should probably not fill up more of this ticket with it -- as long as someone else can do some testing!

Build against current 4.7.2_alpha0 on linux amd64. No problem that can be attributed to pari after running the long tests.

By deleting most of my ~/.sage I successfully ran all the tests (i.e. make ptestlong completed successfully). This is on 64-bit ubuntu.
Sorry for the noise -- is there any reason not to give this a positive review and get it into the 4.7.2 series as soon as possible?

Positive review for trac_11130-doctest-poly.patch and 11130_sagelib32.patch. To make things simpler, I have folded these two patches into my 11130_sagelib.patch (in any case, the commit message of one of your patches needed to be fixed). Together with John's earlier review of my 11130_sagelib.patch, this one patch now has positive review.

John, your patch changes the functionality of the simon_two_descent()
function by adding a new option store_gens
. I have two problems with this:
- I think a ticket related to upgrading PARI is not the correct place to make such a change (or at least, it should be justified why).
- I don't like how
store_gens
changes the output of the function. The name op this option does not imply that the output would be changed. I can agree that you store the saturated points (as before), but why also return the saturated points? This is a real functional change.

I am currently testing this. To avoid duplication of effort, I'll fix things I find in the elliptic_curves directory only.
