The new ellap (which replaces the sea.gp script in sage) is seriously buggy, evidently. Sometimes it works, but the first example I tried fails miserably.
? ellap(ellinit([1,2,7,4,3]),nextprime(10^20)) %1 = -4070602678 ? ellap(ellinit([1,2,3,4,5]),nextprime(10^20)) *** at top-level: ellap(ellinit([1,2,3 *** ^-------------------- *** ellap: bug in PARI/GP (Segmentation Fault), please report *** Break loop: type 'break' to go back to GP break> ? ellap(ellinit([1,2,3,4,5]),nextprime(10^25)) %2 = 1231939791654 ? ellap(ellinit([1,2,3,4,5]),nextprime(10^30)) %3 = 1790178944607137 ? ellap(ellinit([1,2,3,4,5]),nextprime(10^35)) *** at top-level: ellap(ellinit([1,2,3 *** ^-------------------- *** ellap: bug in PARI/GP (Segmentation Fault), please report *** Break loop: type 'break' to go back to GP break>
NOTE: To use ellap for big p, you *must* put the extracted data from seadata.tgz/data/* in local/share/pari, as explained here: http://pari.math.u-bordeaux.fr/packages.html
I'm reporting this bug upstream now.

As of right now, you can install this into 4.4.4 by doing:
1.
./sage -f -m http://sage.math.washington.edu/home/wstein/patches/pari-2.4.3.svn.p3.spkg
- import the patch called sagelib_9343.patch to the main Sage repo.
- import the patch extcode_9343.patch into the SAGE_ROOT/data extcode.

eclib compiles and runs fine with 2.4.3. It even now compiles with -ansi (which was not true before) and almost with -pedantic (just 4 extraneous semicolons need deleting; not worth a new spkg version).
comment:29 Changed 10 years ago by
lcalc has some problems with pari-2.4. I am not sure yet if they are minor or major.
Lcommandline_elliptic.cc: In function ‘void data_E(char*, char*, char*, char*, char*, int, Double*)’: Lcommandline_elliptic.cc:124: error: ‘lgeti’ was not declared in this scope make[1]: *** [Lcommandline_elliptic.o] Error 1
I'll be checking genus2reduction next.
comment:30 Changed 10 years ago by
lcalc problem is minor. Not sure why pariold.h is not properly included when it should be sourced from pari.h (in pari-2.3 it was sourced from paricom.h itself included from pari.h). Anyway replacing lgeti by (long)cgeti as would be done by pariold.h works like a charm.
comment:31 Changed 10 years ago by
genus2reduction suffer the same kind of problems. But it is more serious:
genus2reduction.c: In function ‘main’: genus2reduction.c:476: error: ‘polun’ undeclared (first use in this function) genus2reduction.c:476: error: (Each undeclared identifier is reported only once genus2reduction.c:476: error: for each function it appears in.) genus2reduction.c:600: error: ‘polx’ undeclared (first use in this function) genus2reduction.c:96: warning: ignoring return value of ‘scanf’, declared with attribute warn_unused_result genus2reduction.c:98: warning: ignoring return value of ‘scanf’, declared with attribute warn_unused_result genus2reduction.c: In function ‘factorpadicnonun’: genus2reduction.c:1676: error: ‘polx’ undeclared (first use in this function) genus2reduction.c: In function ‘polymini’: genus2reduction.c:1701: error: ‘polx’ undeclared (first use in this function) genus2reduction.c:1712: error: ‘zero’ undeclared (first use in this function) genus2reduction.c:1731: error: ‘un’ undeclared (first use in this function) genus2reduction.c: In function ‘discpart’: genus2reduction.c:1818: error: ‘polun’ undeclared (first use in this function) genus2reduction.c: In function ‘polyminizi’: genus2reduction.c:1856: error: ‘gi’ undeclared (first use in this function) genus2reduction.c:1859: error: ‘polx’ undeclared (first use in this function) genus2reduction.c: In function ‘polyminizi2’: genus2reduction.c:1939: error: ‘polx’ undeclared (first use in this function) genus2reduction.c:1942: error: ‘gi’ undeclared (first use in this function) genus2reduction.c: In function ‘zi2mod’: genus2reduction.c:2001: error: ‘gi’ undeclared (first use in this function)
polun, polx, zero and un were all defined in pariold.h but are not anywhere anymore in pari-2.4. I cannot track the definition of gi in anything from pari-2.3, anyone knows where that come from and what it should be replaced with? There is a line in pari-2.3 headers mentioning it but not a definition of it as far as I can see:
#define is_universal_constant(x) ((GEN)(x) >= gen_0 && (GEN)(x) <= gi)
this is in paristio.h form pari-2.3.5.

"Seems to"? The Sage test suite is a much better test suite for PARI than pari's own, IMHO.

I am working on the number field code in sage/rings/number_field/* Lots of doctests simply fail because ideals have different generators: "Fractional Ideal (a)" is the same ideal as "Fractional Ideal (-a)" but of course this makes doctests fail.

- Milestone changed from sage-4.5 to sage-5.0
Replying to cremona:
It's at http://pari.math.u-bordeaux.fr/cgi-bin/pkgreport.cgi?pkg=pari (#1075)
Karim Belabas writes:
Simpler symptom: nffactor(polcyclo(21,y), x^2-y^7); This is actually unrelated to #1070. It was due to an nf being replaced by nf.pol --- because we use Trager's trick in that range instead of a direct relative factorization, and don't need the nf data ---. Unfortunately, a branch of the code later tried to acces nf.index, thus accessing a random coefficient of the defining t_POL instead of the relevant nf data. Fixed in svn. Cheers, K.B.
so we now have another reason for upgrading the source in the spkg.

Sorry to disrupt this little love-in here, but that bug has already been found (#9205) and fixed, and the patch has a positive review, and will probably be merged in the next alpha.
There are about a hundred patches with positive review waiting on trac, many of which have something to do with number fields (as a consequence of the big number theory Sage days at MSRI). I'm disappointed to realise that you folks haven't taken this into account, which will most likely mean that your work getting the number theory code to pass doctests with the new Pari version will be reduced to complete junk when all your patches fail to apply to the next alpha.

It is related to the PARI upgrade because the new version of PARI fixes discrete logs (so, it fixes also #9205). Doing the upgrade of PARI made a doctest fail, because the "expected" result from the doctest was wrong.

That's pretty harsh. Anyway, the pari upgrade is higher priority, so in fact it will be the other way around.

When you use gp
it is running the command in a subprocess. Thus you'll never see any (nontrivial) CPU time.

comment:55 Changed 10 years ago by
I think I just had a small break-through:
The gp command now has the so-called "breakloop" on by default. This means the following: if Sage executes a command through the gp interface which gives errors, the following will be displayed in the pseudo-tty (invisible to the Sage user):
? 1/0 *** at top-level: 1/0 *** ^-- *** _/_: division by zero *** Break loop: type 'break' to go back to GP break>
Now gp just waits for user input. Since that input will never come, it just sits there forever.
I have a temporary workaround for this: in the directory SAGE_ROOT/local/bin, move "gp" to "gp-real". Then create the following shell script called "gp":
!/bin/bash mkdir -p $HOME/sage_debug export HOME=$HOME/sage_debug echo "breakloop = 0" >$HOME/.gprc # Remove --fast option exec $SAGE_ROOT/local/bin/gp-real --emacs --quiet --stacksize 100000000
This changes $HOME and makes a .gprc file in it which disables the break loop. It then runs gp without --fast, so that the .gprc file is read.

So, does you patch sort out all those issues (as well as the easy defult() ones)? If so, I clearly have wasted a lot of time today. This example makes it clear how extremely important it is that people say clearly what tey are working on. And I DID say clearly that I was working on everythin the elliptic_curves directory, which includes all the code which calls the Dokchiter script.
On your other point, well spotted. But would it not be simpler to send to the gp process on initialization the command gp._eval_line('breakloop=0;') ?

Well, I fixed the dokchitser script so it would pass some doctests in number_field.py. But my fixes are very trivial (it took me no more than 5 minutes), so maybe you are making more serious changes to the file. In that case, you can safely ignore my patch.

Certainly, yes. That's why I called my solution a "work-around". What you want to do is every time a gp process gets started, the first line should be
default(breakloop,0);

Apologies for this outburst. I did waste time, but only because of my inferior gp-script debugging skills. Thanks to Jeroen there is a much simpler fix for what was troubling me!

I always compile my own copy of PARI/GP with -O3 -fomit-frame-pointer -march=core2 using the latest gcc and that seems to work fine.
The answer is at #7092: because of a failure to build pari with gcc-4.4.1 as distributed by Fedora 11, on ALL Linux systems the OPTFLAG is set to -O1 instead of -O3. Is there not a way to detect that particular compiler-distro combination? Otherwise all Linux users suffer!

It was a big mistake that #7092 got a positive review (from Jaap), and another mistake that the release manager (me) didn't reject that review. Anyway, thanks for tracking this down -- we should definitely make that -O1 hack only Fedora 11.

The type at the start of spkg-install is in the current version of pari. I'm puzzled it works at all, but it seems to.
I was mistaken on the LINKER FLAGS, as that include CFLAGS, so the -m64 will get there from that.
However, this still thinks gmp is broken. The version of Pari in Sage at the moment reports:
Checking for optional libraries and headers... ...Found libgmp in /rootpool2/local/kirkby/sage-4.5-hacked-for-64-bit-solaris/local/lib ...Found gmp header in /rootpool2/local/kirkby/sage-4.5-hacked-for-64-bit-solaris/local/include Using GNU MP, version 4.3.1 ...Found libX11 in /usr/openwin/lib ...Found X11 header files in /usr/openwin/include/X11
compared to this version, where I see:
Checking for optional libraries and headers... ...Found libgmp in /export/home/drkirkby/sage-4.5/local/lib ...Found gmp header in /export/home/drkirkby/sage-4.5/local/include ld.so.1: solaris-ix86-rlv23868: fatal: libgmp.so.10: open failed: No such file or directory ./Configure[79]: .: line 38: 24072: Killed ### Your version of GMP is too old for PARI.

So something has changed for the worst.
This version from svn wants bison too, so you will have to generate the files, since bison is not a prerequisite for Sage, and is not included in Sage.

Hi, John or someone else can perhaps convey this to the Pari developers. Would it be possible for them to add the -fPIC option on at least all Solaris systems. (Both SPARC and x86). If code goes into a shared library, it should be compiled position independent. It is unreliable if this is not done. There's some relevant information about this here.
http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Code-Gen-Options.html#Code-Gen-Options http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Link-Options.html#Link-Options
I believe it would be more reliable to build with -fPIC when the code is going into a shared library - irrespective of the platform. What one should ensure though is there is not a mixture of PIC and non-PIC code, as that can be unreliable too.
I've not had a chance to look at the other issues, but as far as I can see, this update completely breaks a 64-bit build on Solaris or OpenSolaris.
I've also noticed that Pari reports that readline is not working on Solaris systems. Yet the readline is definitely working in my Sage builds on Solaris. Several parts of Sage link against readline (Pari, gap, Singular, ECL, Python ...). None of them believe that readline is broken, but Pari does.

Looking at the error message above:
ld.so.1: solaris-ix86-rlv23868: fatal: libgmp.so.10: open failed: No such file or directory ./Configure[79]: .: line 38: 24072: Killed
and comparing it to the GMP libraries that were installed, the version numbers do not match. Pari is looking for libgmp.so.10
but I have the following GMP related files:
drkirkby@hawk:~/sage-4.5/local/lib$ ls -ld libgmp* -rwxr-xr-x+ 1 drkirkby staff 803 Jul 16 13:10 libgmp.la lrwxrwxrwx 1 drkirkby staff 15 Jul 16 13:10 libgmp.so -> libgmp.so.3.4.6 lrwxrwxrwx 1 drkirkby staff 15 Jul 16 13:10 libgmp.so.3 -> libgmp.so.3.4.6 -rwxr-xr-x+ 1 drkirkby staff 549536 Jul 16 13:10 libgmp.so.3.4.6 -rwxr-xr-x+ 1 drkirkby staff 919 Jul 16 13:10 libgmpxx.la lrwxrwxrwx 1 drkirkby staff 17 Jul 16 13:10 libgmpxx.so -> libgmpxx.so.3.1.6 lrwxrwxrwx 1 drkirkby staff 17 Jul 16 13:10 libgmpxx.so.3 -> libgmpxx.so.3.1.6 -rwxr-xr-x+ 1 drkirkby staff 26712 Jul 16 13:10 libgmpxx.so.3.1.6
i.e. there is nothing like a version 10. The installed libraries have a 3.x in them, but Pari is looking for a .10.
I've installed bison on the system, so the error message about a missing bison is not appearing any more, but that has not resolve either
- The readline issue, which I've had for ages. OR
- The gmp library issue, which is unique to this update, and does not show up in the version in Sage.

Thanks. I finished fixing the interfaces/gp and very nearly finished libs/pari/ . The serious issues are gone now. I fear that the flood of newly merged tickets for 4.5.2 will require some rebasing, so as soon as I have tidied up I will post the revised patches and a new spkg (p5). I have not touched anything in number_fields since you did, but it still might be a good idea to wait until I have posted what I have done.

I was planning to do this (report upstream). On the positive side, they just put in a patch which obviates the need for 2/3 of our patch to the header files paripriv/paridecl.h.
I think we will have a better chance of a positive reaction if we could report to pari a failure to build of pari as such and not pari-in-Sage, since they would reasonably reposond that as we patch some files they cannot be responsible. For this, just copy the src directory of the most recent spkg (or wait until I put up p5 later today) and try it directly, after ./Configure <whatever-params> and make whatever.

John, I'm going to attach to the ticket a failure observed with the Pari source code directly - outside of Sage. No compiler flags were set.
The hack of mine in Sage (adding -fPIC
) resolves this, but it would be better if it could be fixed upstream. The file was actually 5.1 MB in size, as there are over 95,000 error messages. I've reduce the filed to 23 KB, but removing tons of very similar looking messages. See the file:
Pari-trunk-failure-on-OpenSolaris_x64.log.txt
There are similar issues on Solaris 10 SPARC. I can attach a log if needed, or someone can just try to build on 't2' outside of Pari. You will see very similar.
I believe this should be applied on all platforms, as it will be more reliable. The code should be position independent if you are building shared libraries.

I mean someone could try this on 't2.math.washington.edu' without using Sage. I'm sure William would set up an account for a Pari developer. They only need the Pari source - no Sage code to reproduce this error.

6 in number_fields:

sage -t devel/sage-main/sage/schemes/elliptic_curves/heegner.py # 6 doctests failed
There is also a failing doctest for tanh in libs/pari/gen.pyx which I disabled temporarily. And there may be some doctests needing different 32-bit output; but I have done enough for now.
Independently of this I have upgraded the spkg to the latest svn, made the relavant changes to the patches in it, and added a spkg-test (with help from David Kirkby). I will put up a link to that when I have succeeded in spkg-ing it.

I think you are mistaken John. Further up the script is
cd src
so another src
would be an error.
I do sometimes think it is better to perhaps consider deleting all patches. I have just updated 'GSL' (#9533). GSL is a much simpler package I admit. I removed all patches. The new GSL package has built and passed all self-tests on Cygwin, Linux, HP-UX, OpenSolaris, OS X and Solaris. (Sage does not build fully on HP-UX, but enough of it builds to prove that GSL passes all tests).
I hope at some point you are going to test on 't2'. I simply do not have the time to test everyones updates on 't2'.

I hope at some point you are going to test on 't2'. I simply do not have the time to test everyones updates on 't2'.
Well I hope someone is, but I'm busy with other things for the next 2 days and then away for 3 weeks without opportunity to do Sage stuff.

Some fixes in sage/rings/number_fields and doctest changes in sage/rings/polynomial/polynomial_element.pyx
comment:99 Changed 10 years ago by
I did a complete from scratch build of sage-4.5.1 with the new patches and did a long doctest. I got some more errors than John:
sage -t -long devel/sage-test/sage/schemes/elliptic_curves/heegner.py # 7 doctests failed sage -t -long devel/sage-test/sage/rings/number_field/number_field.py # 18 doctests failed sage -t -long devel/sage-test/sage/schemes/elliptic_curves/ell_point.py # 2 doctests failed sage -t -long devel/sage-test/sage/schemes/elliptic_curves/ell_generic.py # 1 doctests failed sage -t -long devel/sage-test/sage/rings/number_field/number_field_rel.py # 3 doctests failed sage -t -long devel/sage-test/sage/rings/number_field/number_field_element.pyx # 2 doctests failed sage -t -long devel/sage-test/sage/rings/number_field/number_field_ideal.py # 17 doctests failed sage -t -long devel/sage-test/sage/rings/number_field/number_field_ideal_rel.py # 3 doctests failed sage -t -long devel/sage-test/doc/en/constructions/algebraic_geometry.rst # 2 doctests failed sage -t -long devel/sage-test/sage/interfaces/gp.py # 2 doctests failed sage -t -long devel/sage-test/sage/schemes/elliptic_curves/ell_rational_field.py # 1 doctests failed
Some are probably because John did not do "long" doctests, but also in some cases I get PariError?: not enough memory. For example:
File "/usr/local/src/sage-newpari-4.5.1/devel/sage-test/sage/schemes/elliptic_curves/ell_generic.py", line 2646: sage: [t[1] for t in EllipticCurve(GF(10^60+3201),[0,a,0,b,0])._p_primary_torsion_basis(2)] Exception raised: [...] PariError: not enough memory (28)
I will have a look at these errors and see what I can fix.

All doctests are now fixed, except for some which hit PARI bug 1079 and some in sage/schemes/elliptic_curves. Apparently, the PARI update increased the memory requirements of some of the doctests, making them fail on my machine with 3GB RAM. However, these doctests already take a lot of memory with the vanilla sage 4.5.1, see also my post at sage-devel.

Bison, like autoconf and automake should not be necessary for end-users. Often developer additions don't have a 'configure' script - they rely on other developers making that from configure.ac. It is the same with bison - some files only need to be geneated and passed to the end users. As long as the timestamp on the files generated by bison is more recent than the files they were generated from, bison should not be necessary.
With regard to my own Solaris issue with -fPCI, shared libraries and Pari, I'm not sure how to observe what is happening, or where I can follow the Pari bug numbers referenced. Essentially one of the Pari developers disagreed with me, and said it is not necessary to use -fPIC when compiling 32-bit shared libraries on Solaris - only 64-bit ones. I responded that this is not so, and provided a link to something written by Casper Dik (a very knowledge Sun employee), that -fPIC is necessary. I gather that was passed on, but I don't see any record of it.
There's also the point I made that Pari is looking for a different version of GMP to what is in Sage when building a 64-bit version of Pari. The Pari developer believes it is finding another version before that one in Sage. IF that is so, that needs fixing in Sage. Somehow we need to ensure Pari first looks for the libraries in $SAGE_LOCAL/lib, and not in /usr/lib, /usr/local, or wherever else Pari may chose to look. The whole point of shipping a bunch of standard libraries with Sage is we know what ones are are used by Sage.

As I see it there are now two main issues:

Have the other issues that are circumvented by hacks to spkg-install been reported upstream? Such as:
# These two are needed so that Sage can catch pari's error signals. cp "$PATCHED/init.c" src/language/init.c cp "$PATCHED/mp.c" src/kernel/gmp/mp.c

Hi Dave we have some of these patch as well in Gentoo (and I mean in the distro
itself not just sage-on-gentoo). So I can fill in some gaps.
get_dlld: we have this
# propagate ldflags sed -i \ -e 's/-shared $extra/-shared $extra \\$(LDFLAGS)/' \ config/get_dlld || die "Failed to fix LDFLAGS"
We add -fpic on all platforms when building the library but not gp or static libraries.
But we have a patch I think originating from Debian to add support
for linux ppc 32 bits.
get_ld: when gp is compiled it uses libpari and is compiled -rpath to hardcode the libray location. I am not sure this is strictly necessary.
Not sure about the CYGWIN and OS X stuff.

My fault. I uploaded a new http://cage.ugent.be/~jdemeyer/pari-2.4.3.svn.p6.spkg which should fix this. (This is a small hack I added such that the SVN version is saved in patches/status such that it can appear in gp.version() for example).

So it seems we should remove the -fPIC patch for PPC Linux, and the -fPIC patch for Solaris will be able to be removed later, but not yet.
IMHO, it would be better to remove all the patch (or just comment them out for now), and put them back as and when they are needed, taking care (where possible), to check if the bugs they are supposed to fix reoccur. This is one of the more messy spkg-install files I've seen - though the ATLAS one is pretty messy too!

Perhaps spkg-check should do one of "make dyntest-all" or "make statest-all" instead of "make test-all" (which does both and takes twice as long)? Since we are only installing one copy of the binary gp (which is what is run in the tests) there's no need to make and test the other.

Why do you chose that name? The .p7 should only be integrated into Sage where there are 7 previous versions of 2.4.3. Since the software says
Shall we try to build pari 2.4.3 (development svn-12543) now (y/n)? [n]
I think a better name would be
pari-2.4.3.svn-12543
as that is the version of Pari that it is based upon. Then, assuming this version was merged, subsequent updates in Sage would be called pari-2.4.3.svn-12543.p0, pari-2.4.3.svn-12543.p1, pari-2.4.3.svn-12543.p2 etc.
Certainly, the first revision put into Sage should not have a patch level of 7.
http://www.sagemath.org/doc/developer/patching_spkgs.html
says If the upstream package is taken from some revision other than a stable version, you need to append the date at which the revision is made, e.g. the Singular package singular-3-1-0-4-20090818.p3.spkg is made with the revision as of 2009-08-18.
However, I think in this case, the fact the upstream does have a version number (in this case 2.4.3.svn-12543), that should be used rather than a date.

The new version has just patches/files/paripriv.h which gets copied on all 3 operating systems.

I've found what the problem with the GMP and Readline are on Solaris. Setting CFLAGS to include -m64 flag is not sufficient, but setting
CC="$CC -m64"
works.
I also made a few other improvements to spkg-install.
- Allow one to set SAGE_DEBUG=yes to set no optimisation. Primarily for debugging purposes, but would also be useful if people (like on Fedora once) found gcc mis-compiled Pari.
- Check SAGE_ROOT actually exists as is required in the Sage Developers guide
- Allow the setting SAGE_TUNE_pari=yes to get increased performance, at a cost of letting Pari do the tuning.
I changed the filename to show the actual svn version - you can see this reported when you run configure.
New package at

What I had been planning to say about the spkg's name is:
I would think it worth keeping the svn snapshot number in there at all times. Even for alpha releases, as it's obvious then if its based on a different version of the upstream source code. Those editing this ticket will be in no doubt if the source has changed or not.
For actual packages in Sage, the Developers Guide says to have the date on SVN snapshots, but since we can get an actual number, that seems more sensible to me. Also, I've found if one puts a date, what often happens is someone updates the package and instead of putting .p0, then just change the date. At that point, the date bears no resemblance to what's in the upstream code on that date.
Anyway, http://boxen.math.washington.edu/home/kirkby/patches/pari-2.4.3svn-12543.spkg
will build properly on OpenSolaris.
I managed to get a core dump when tuning it, but that's less of an issue. I will report that upstream. I've found Bill very helpful. I've just reported the CC/CFLAGS bug upstream, though have got no feedback yet.
I can see tuning Pari is slow. I can build Pari in 33 seconds on this machine, but it was 24 minutes until I got a core dump when tuning. So I don't know how long tuning would take. But it seems sensible to give the user that option if they are blessed with lots of computer power or lots of patience. Looking at some of the timing data, it looked like the differences in algorithms was significant, and so worth optimising if you want to make a lot of use of Pari.
BTW, the source code in that package is the same as created by jdemeyer, and is not the latest upstream code as I write. But I chose not to change the source code - just spkg-install, so it will work properly on OpenSolaris.

cp: cannot access /export/home/drkirkby/sage-4.5.2.alpha0/spkg/build/pari-2.4.3svn-12543/patches/files/get_dlld
That's nothing I've touched - it appears in the previous version too. Seems like a patch that one tries to apply does not actually exist.

Minor improvements to spkg-check. Correct list of dependancies in SPKG.txt - they are MPIR, readline and termcap.
comment:136 Changed 10 years ago by
As noted, I improved spkg-check a bit. I just overwrote the package here
http://boxen.math.washington.edu/home/kirkby/patches/pari-2.4.3svn-12543.spkg
SPKG.txt needs to have all the changes made put into the file. It previously said the dependancy was GMP, but in fact it depends on MPIR, termcap and readline. Luckily spkg/standard/deps
does have the dependencies correctly listed.

It was agreed long ago on sage-devel that packages would be built with debugging information by default, since it makes finding bugs a lot easier. I initially thought that was a bad idea, as it increases the size of the objects. But it is negligible, and it makes no difference to run-time, so I concede it is sensible. That's the reason for the -g
Some software packages add -g anyway, in which case it could be removed, though I'm not sure its a good idea, since if the software changes that behaviour, we have lost the ability to easily debug problems.

New version of the PARI spkg: http://cage.ugent.be/~jdemeyer/sage/pari-2.4.3svn-12549.spkg.
Removed the non-existent get_dlld patching. Cleaned up patches/README.txt
comment:140 Changed 10 years ago by
Breaking news: I have succesfully built Sage 4.5.2.alpha0 from scratch with all the updates so far (without any trace of the old PARI package). This means that no other spkg's have to be fixed.
So I think the TODO list reduces to:
- Fixing the remaining doctest failures.
- Testing on as many platforms as possible.
- Reviewing everything and cleaning up.
I can help with the first and third of these, but not really the second.

No, the problem is upstream. Building PARI from SVN (outside of Sage, that is) now fails make test-all. I am reverting to 12546, that seems to work.

make test-all
will always fail with just the upstream source unless some of the tests are disabled, since they rely on one or more databased that are not in Sage unless optional components are installed.

The last patch fixes the tanh() issue, it was caused by RR(0.0)._pari_() creating an invalid GEN (it took me a very long time to figure this out).
I added a debug() function to gen objects calling dbgGEN() from the pari library, example:

What concerns me, is all this updating of svn. Sure some bugs might be fixed, but others are getting introduced. It would be nice if there was a stable version. Every time you update, so the testing needs to be done again. There was an earlier case I evaluated which it was ok, then someone updated and it was broken.
There's no point keep testing the code, if the source gets updated.
Personally, I'd revert to the svn which underwent a fair amount of testing.

To be more precise, 12543 was ok, 12549 failed all tests. What bugs has 12577 introduced?
Is there any chance of convincing the Pari developers to actually make a well-tested stable release? The Pari developers can make commits to svn more rapidly than Sage developers can test the code. That's 34 different source versions in 13 days. Would anyone like to try to convince me these are well tested?

We might discover bugs in PARI itself as well, which hopefully would get fixed upstream (quickly in the svn, but probably not immediately in a [new] stable version). I though would prefer to base the new spkg on an "official", i.e. stable version, too.
Personally, I'd revert to the svn which underwent a fair amount of testing.
I think since it seems a whole release will be dedicated to updating PARI, there will be enough testing anyway. But of course we'll have to freeze our snapshot at some point, when the appointed Sage release date/cycle comes close(r).

Well, I agree that we shouldn't upgrade the source all too often. But if the PARI developers fix a bug that we found, that is a good reason to update (and that is also why I updated to 12577).

I've changed the title to reflect more accurately what the ticket is. It's not an update to version 2.4.3 of Pari. Version 2.4.2 has not even been released - only an alpha of that is available
http://pari.math.u-bordeaux.fr/pub/pari/testing/pari-2.4.2.alpha.tar.gz
This is an svn snapshot, but the ticket title implied something quite different.
Note the developers guide says the date the snapshot was downloaded should be in the package name. However, that seems to cause confusion to me, as when people update the package, they keep changing the date, rather than adding .p0, .p1, .p2 etc. In any case, different snapshots can exist on the same day. Putting the actual snapshot number seems more sensible to me. So I think it would be better if this was called pari-svn12577.spkg, to reflect that fact it is a snapshot, and not a stable release as the package name would imply. Otherwise follow the developers guide. IMHO, this should not be called pari-2.4.3.
When 2.4.3 is released, it would seem sensible Pari is updated to a stable release. But that's less likely to happen if people see from the package name that we already have the latest release.
Of course, if the snapshot that's used gets updated, then that should be reflected in the ticket title!
BTW, before thinking about updating the snapshot once again, take a read of of the book The Mythical Man-Month in particular one of the authors points that in a suitably complex system there is a certain irreducible number of errors. Any attempt to fix observed errors tends to result in the introduction of other errors. I've certainly experienced this before many times - including a previous snapshot on this very ticket.

comment:174 Changed 9 years ago by
I suggest that when we are close to having a version of all this which we want to release (as 4.6.alpha0 or whatever), which is soon now, we (William or me probably) let the two lead Pari developers know that this is happening, and tell them which svn version we are considering going with. It may be that they recommend waiting for some bugs they know about and have nearly fixed. (But we cannot wait for ever, of course.)
It is also possible that they may be pleased that a certain Pari version has had extensive testing through being part of a Sage release (and they may even say so, though that is slightly less likely). In any case, when the new spkg and all the related patches are in Sage then it will be very easy to upgrade to to a new Pari svn for new bug fixes.

Following the detailed instructions in the ticket description, starting with a fresh build of 4.5.3.alpha0, I successfully installed the three spkgs (with SAGE_CHECK='yes') and both patches (sagelib and extcode) with no issues -- except that when I tried to install the lcalc spkg, it said "already installed", which I do not really understand. Jeroen?
Then, sage -tp 10 -long passed everything! So the rebase to 4.5.3.alpha0 is fine.
elliptic_curves/ell_rational_field.py: I checked that the new output from the doctest is as valid as the old one (there is just a slightly different LLL-reduced basis, which is a reasonable side-effect of changes to the pari library which does the LLL reduction).
I am uploading an extra little patch fixing that. Which just leaves heegner,py.

This is because the package at #9592 has the wrong name (it should be rebased on #9665 which is p1, and renamed to p2.)
Ahah! Well, as I said, everything worked and passed, so perhaps this means that no upgrade of lcalc is required after all?

Ahah! Well, as I said, everything worked and passed, so perhaps this means that no upgrade of lcalc is required after all?
John, could you try reinstalling the "old" lcalc p1 package (by ./sage -f ...

Perhaps this would show the error #9592 (Jeroen's new lcalc spkg) is intended to fix.

I did that and it does not show the error. Note that Jeroen's patch at #9592 just changes one source file (src/Lcommand_line_elliptic.cc) and in that file changes
F[1] = lgeti(BIGDEFAULTPREC);
to
F[1] = (long)cgeti(BIGDEFAULTPREC);
and 4 similar lines. It is possible that during our work on this ticket some change in Pari means that old version works again. So I think that we can cancel #9592 and remove the new spkg from the instruction on this ticket. I will try that and report back.

OK, I see what is happening now. Applying JD's version of the lcalc patch does not work since there is a different p1 version of that which is now in the standard distribution (for 4.5.3.alpha0) so it does nothing when you try to install it since the name is the same.
I will take the real p1 from #9685 and add JD's extra patch to Lcommandline_elliptic.cc (being careful, since there's already a patch for that file) and make a p2 from it, then post a link to that here.

That should have said #9665; and in fact I can take it from SAGE_ROOT/spkg/standard from 4.5.3.alpha0.

See related discussions at #9665. The new lcalc spkg should be replaced by the one there.[Jeroen's p1 has been superceded by the p1 at #9665 which has now been merged. There's a suitable p2 at that ticket which can be linked to here after testing.]
I checked that the lcalc p2 spkg from #9665 builds fine (and really does build!), and am re-testing everything.

Yes. I could reproduce the build error of the old lcalc spkg with new PARI; John's new one (p2) at #9592 (Jeroen's p1 rebased on Sage's current one) builds.
The number (and type) of warnings I get by doing so (building lcalc) though is IMHO a shame. Besides other annoying warnings, there are twelve deprecation warnings (with gcc 4.4.4). (Of course many warnings have the same origin, but that makes fixing them even easier. This isn't meant as an offense, but rather a suggestion.)

--- The difference is just that the vectors with given norm output by pari are now in a different order. This causes some output to be slightly different in Sage, but is not a bug. So it is 100% safe to change the output in heegner.py to match what gets output now.
---
Regarding the error in ell_rational_field.py -- the *only* remaining issue -- this is a doctest that John Cremona introduced for trac 4525: http://trac.sagemath.org/sage_trac/ticket/4525
The difference is that "a" LLL reduced basis is now slightly different. This seems extremely plausible, since PARI's LLL code was completely changed in this new version (I recall Bill A. telling me they incorporated a version of fplll into PARI). So very likely that doctest is fine too. John C is the one who should sign off on it though, not Robert B (you're in the clear).
I've taken the liberty of posting a patch that fixes the heegner.py tests, and also the one LLL test in ell_rational_field.py (though I'd like to hear from John C. about that).

William, I had already posted a patch for the LLL-reduced basis thing (see a few comments up) but you can be forgiven for not noticing it in this crowded ticket! Yours does the same as mine and also fixes the heegner stuff, so mine could be deleted. [Your diagnosis is 100% correct]

#9591 (genus2reduction) still needs to be resolved I believe. That's not even marked for review.
I wish I knew why people keep putting tickets related to this being due to a upgrade to pari 2.4.3, when not even 2.4.2 has ever been released.

Yes: from http://pari.math.u-bordeaux.fr/ we see:
* PARI is a C library, allowing fast computations. * gp is an easy-to-use interactive shell giving access to the PARI functions. * GP is the name of gp's scripting language.

The official name of MATLAB is MATLAB, but still the Sage has:
Mission: Creating a viable free open source alternative to Magma, Maple, Mathematica and Matlab.
I've tried suggesting we call MATLAB by its official name, but that fell on deaf ears.
In general, I'd rather call programs by their official name, though in same cases, the programs themselves are not consistent!

I just tried the steps outlined at the top.
- Pari installed ok
- genus2reduction installed ok
- lcalc installed ok.
- extcode_9343_combined3.patch patch to data/extcode installed ok.
Then when I tried to apply the library patches, I was less than successful. I'm not sure though if the
hg qpush -a
was the right thing to do after hg qimport
of the library patches. So I could have made a mistake, but this is what I did, and this is what results I got. (This is an OpenSolaris system, which apart from some numerical noise issues, and a totally busted sympow
otherwise passes all the doc tests.)

You're applying the patches in the wrong order. I usually do

which should work fine. Maybe there is a better way, I don't know much about Mercurial.

My complete new spkg and patch install and test on a 32-bit Ubuntu (Intel, gcc 4.2.4) went smoothly, with only the 32/64 issues with the new analytic rank as Jeroen found. So I popped the last patch and pushed the replacement, and now that works fine.

Sure -- what is (possibly) counter intuitive is the *order* in which they are applied, which is the reverse of the order they were imported. For this reason I find "hg qpush -a" rarely useful.

I decided to test the http://cage.ugent.be/~jdemeyer/sage/sage-4.6.prealpha0.tar on my OpenSolaris machine. Sage has never passed all the doc tests on OpenSolaris, so I did not expect it to. I'll list the failures and what I think they are due to. There's one unexecpted failure.
A better test would be on 't2', but that takes forever to build Sage. This is an order of magnitude quicker.
The following tests failed: sage -t -long devel/sage/sage/lfunctions/sympow.py # 13 doctests failed sage -t -long devel/sage/sage/rings/polynomial/polynomial_quotient_ring.py # 1 doctests failed sage -t -long devel/sage/sage/modular/abvar/abvar.py # 1 doctests failed sage -t -long devel/sage/sage/modular/hecke/submodule.py # 1 doctests failed sage -t -long devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py # 17 doctests failed sage -t -long devel/sage/sage/stats/hmm/chmm.pyx # 3 doctests failed sage -t -long devel/sage/sage/symbolic/expression.pyx # 2 doctests failed ---------------------------------------------------------------------- Total time for all tests: 1913.9 seconds
1) devel/sage/sage/lfunctions/sympow.py
SYMPOW is the worst code I've ever seen in Sage and is broken on Solaris x86 (#9703), Cygwin (#9166) and reportedly ArchLinux too. The examples at http://www.sagemath.org/doc/reference/sage/lfunctions/sympow.html do not work if you try them on sage.math, so I we can ignore this failure. The code in SYMPOW is so bad, I can't really be bothered to try to fix it.
2) devel/sage/sage/rings/polynomial/polynomial_quotient_ring.py
An unexpected failure.
3) devel/sage/sage/modular/abvar/abvar.py
Caused by SYMPOW. So we can ignore that.
4) devel/sage/sage/modular/hecke/submodule.py
Again, caused by SYMPOW, so we can ignore that.
5) devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py
Again, caused by SYMPOW, so we can ignore that.
6) devel/sage/sage/stats/hmm/chmm.pyx
This is numerical noise, #9735, which will hopefully be merged soon.
7) devel/sage/sage/symbolic/expression.pyx
Again numerical noise (#9689 & #9693).
So the unexpected failure I see was this one:

Note the machine I used is 64-bit (it has a quad core 3.33 GHz Intel Xeon W3580 CPU), but the build was performed 32-bit. Both Solaris and OpenSolaris build 32-bit applications by default - for 64-bit, you need to add the -m64
compiler switch when building. The 64-bit builds of Sage are not very successful yet.
Does anyone know what the result should be? For the first result, I get the real number 2.9757207403766761469671194565
but the expected value is the complex number 2.9757207403766761469671194565 - 1.2983430720865060515202099613e-47*I
So for the real part I get exactly the same number, but I get no imaginary part whatsoever.
I assume someone here must know the maths behind this, and know whether the result is supposed to be real or complex. If it should really be real (so the number I got is actually the more accurate of the two), then putting dots would be very dangerous. Then a result of 2.9757207403766761469671194565 + 1e300*I
would still pass! That's almost entirely imaginary, with a very small real part in comparison to the massive imaginary component.

Maybe rather than directly testing the answer, one could do something like this:
sage: x = [calculation]; abs(x - 2.975975720740376676146967119) < 10^(-27) True
That would be less dangerous, while still allowing the necessary flexibility.

The first question I personally need answering is should the number be real or complex?
I might guess the small imaginary component should not be there at all, but would my guess be right? I'm not a mathematician.
Only when I know the answer to that question do I feel able to comment on a test.
Given the number of digits that are printed (> 16), this would suggest to me that arbitrary precision maths is being used, and not just a floating point processor. If so, the answer should be the same irrespective of whether the machine is 32-bit or 64-bit. Rounding errors occur in floating point processors - they do not on integer arithmetic if done properly.
If this is being done with just an FPU, then printing these number of digits is a bit pointless.

It is real. The list is the list of values of z^2
as z runs over the roots of f = x^5 + x + 17
, which has exactly one real root, listed first. Apart from precision the output should be the same as
sage: [z[0]^2 for z in f.roots(CC)] [2.97572074037668, -2.40889943716139 + 1.90254105303505*I, -2.40889943716139 - 1.90254105303505*I, 0.921039066973047 - 3.07553311884578*I, 0.921039066973047 + 3.07553311884578*I]
The function being tested is rather general, so one could not expect the function's code to test for this special case (I think). Still, it is disappointing that the imaginary part is not a better approximation to zero than it is.

It is a complex embedding, so the output is a ComplexNumber, ideally with real part zero. The precision is 100 bit. This indeed makes 10^{{-27} a bit disappoint. }

Whilst the doctest can be changed to make this pass, is a real bug being covered up?
Can anyone explain why a calculation performed with integers should differ depending on whether the program is compiled 32-bit or 64-bit? Since to me, of the arbitrary precision maths is implemented correctly, they should give the same result. I never get any issues like this with the MPFR tests.

Replying to drkirkby:

I would rather say on the contrary. The problem was that we were computing the roots of a polynomial with complex non-exact roots. I.e.: instead of computing the roots of x^{5+x-17, we were computing the roots of (1.0 + 0.0*I)*x}5 + ... I changed that in my patch.
Can anyone explain why a calculation performed with integers should differ depending on whether the program is compiled 32-bit or 64-bit? Since to me, of the arbitrary precision maths is implemented correctly, they should give the same result.
This is not always true because the precisions might be different. In PARI, the precision is always a multiple of the machine word size. If you try to compute with 90 bits of precision, you will get 96 bits of precision on a 32-bit machine but you will get 128 bits of precision on a 64-bit machine.
If might be possible to change this such that PARI always uses a multiple of 64 bits of precision (I have been thinking about this), but it's not so easy.

OK, fair point. Now I understand. I was under the impression 100 bits were being used.

I copied all the authors to reviewers, as I think everyone that has wrote part of it has reviewed part of it. I also added Leif and François as reviewers, as they have contributed too. But I've not done an extensive search to see who should be on the reviewer and the author list. I suspect there are some missing.

I'm pretty sure this will fix it. In PARI 2.3.x, we patched get_dlcflags

I think spkg-install

- Shouldn't
SAGE_TUNE_pari
beSAGE_TUNE_PARI
? - I don't understand why we unconditionally add
--graphic=none
to./Configure
. (This is already added if$PARI_EXTRA_OPTS
are empty.) - The test of
$?
at the bottom is redundant/superfluous, or even wrong; we should simplyexit 1
there, or change the wholeif-then
logic, e.g. usingelif
. (Shouldn't it be a build error if$SAGE_LOCAL/lib/libpari.so

I forget who it was, but someone proposed something like this SAGE_THREADS_$packagename where the '$packagename' would be lower case. I think that's quite a reasonable idea. It potentially allows the name to be automatically generated.
If you want to clean it up, it would be better to open another ticket for that.

When were these dropped - since I tested this on OpenSolaris, or are these other changes? I can't keep up with the changes on this ticket!
Without trying to build in HP-UX I don't know for sure what will be needed, and I don't have time to try that now.

In that case, it's pointless worrying about them now. Sage will not build with SunStudio? and does not build on HP-UX. These are two things I'd like to fix (especially the former), but they are not critical to this ticket. Any issues like that can go on another ticket.

comment:281 Changed 9 years ago by
I can confirm what John found on 't2.math' - this package is now broken on Solaris 10 SPARC in at least 32-it mode.
This is on my own personal machine, a Sun Blade 1000 with a pair of 900 MHz UltraSPARC III+ CPUs. It runs the very first release of Solaris 10 (March 2005), whereas t2.math runs a quite recent version.
I think we are seeing the problems of working with unstable snapshots. An updated Pari was working on 't2' a few weeks ago - I posted the list of test failures above. Since then, the snapshot has been updated, which no doubt fixes one problem, but creates another. Last I noticed, the upstream snapshot was being updated three times per day on average. Clearly the snapshots are not well tested, yet we are using them, and doing the tests ourselves.
I suggest that we report this, and try to get a fix. But rather than download the latest snapshot, we just apply the fix we actually need. Otherwise we have to go thought a lengthly test cycle again. I'm sure it will be tempting to update to the latest snapshot to get even more bugs fixed, but how many will be added?
Worth reading is a book by Fred Brooks called The Mythical Man-Month.
Of particular note here is is point that that in a suitably complex system there is a certain irreducible number of errors. Any attempt to fix observed errors tends to result in the introduction of other errors.

Hmmm, I reproducably get (PARI-catched) segfaults (everytime at the same point) on Ubuntu 9.04 x86_64 (Core2, gcc 4.5.0)...
Same here, Gentoo Linux, x86_64 Intel Core2, 64bit, gcc 4.6.0.
So tuning is completely broken.
It works on OpenSolaris - or at least it did do when I tested it before.

It's now busted on OpenSolaris too!

Btw, FLTK-devel was installed (and almost all X11 developer packages); PARI correctly did not attempt to build with this (since we configure with --graphic=none

I think I've found the culprit of #9722 (PARI attempting to use FLTK for no reason): Lots of "local" variables used in the PARI scripts aren't reset/initialized.
Try, e.g.:
$ export with_fltk=yes $ ./Configure --graphic=none
in the PARI source directory, or
$ export with_fltk=yes $ unset PARI_EXTRA_OPTS $ ./sage -f pari-2.3.5.p2 # or the appropriate PARI version, e.g. 2.4.3.svn-12577.p2
in $SAGE_ROOT
.
comment:293 Changed 9 years ago by
(The above doesn't fail in all cases, but PARI attempts to use X11 or FLTK despite --graphic=none
given. On Ubuntu, I had to create a symbolic link from /usr/lib/libfltk.so
to /usr/lib/libfltk.so.1.1
to produce the compilation error reported at #9722, with X11 developer packages, and with just FLTK, not FLTK-devel installed.)

Thanks for setting up the Wiki page.
I'm working on #9722 btw, still hoping that it will make it into 4.5.3, since I don't believe 4.6 will be ready in time, and/or don't expect people to install a brand new major release (despite the ".0" missing) right before a new semester starts.
I'll take a closer look at p3 later; I don't think PARI_EXTRA_OPTS

Jeroen, IIRC 4.6.prealpha1 is based on 4.5.3.alpha0, and doesn't contain all of the latest (#9343) changes, so perhaps update/correct the Wiki page s.t. people will test the lastest PARI(-related) spkgs and patches, not the old one(s) contained in the complete Sage distribution.
Please excuse if I'm wrong here...
(In case you prepare a new one, I think it should be prealpha2 to avoid confusion with the previous one.)

comment:302 follow-up: ↓ 392 Changed 9 years ago by
I found out what prevents PARI/GP from compiling on Solaris. The problem is that /bin/sh
from Solaris doesn't know about test -e <filename>
.
So there are two solutions:
Solution 1: In Configure
, replace
#! /bin/sh
by
#!/usr/bin/env bash
Solution 2: In config/Makefile.SH
, replace all occurances of
test -e
by
test -f
Using either of these solutions makes PARI/GP compile.
Since Sage assumes the existence of bash
, we might as well apply the first solution anyway. I will report this upstream.

Any changes in p4 / prealpha3 other than the Solaris fix?
In sage-4.6.prealpha3, I merged #9703 and #9735 which hopefully makes Sage pass all tests on Solaris.
It was not necessary to include #9703 and #9735 for Sage to pass all doc tests on Solaris 10 (SPARC), which is the only currently supported version of Solaris on Sage. Both of those tickets only affect x86 versions. They will not do any harm, but they were unnecessary.
However, since #9703 has been merged, I would request that anyone that builds sage-4.6.prealpha3.tar, that they report on ticket #9703 of the success or failure of these three tests:
sage -t -long devel/sage/sage/modular/abvar/abvar.py # sage -t -long devel/sage/sage/lfunctions/sympow.py # sage -t -long devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py
#9703 still awaits positive review, so clearly evidence it is working on many systems will add to the confidence that the ticket is valid. Just adding a quick comment like "The three tests passed on <your system>" would be useful.
Neither are those two tickets sufficient to cause all doc tests on Solaris 10 on x86 or OpenSolaris on x86, though they will reduce the number of failures. A couple more tickets need to be merged to get all doc tests to pass on Solaris 10 x86 - these are #9689 and #9693. However, that's outside the scope of the Pari upgrade, so I'm not expecting you to merge them, though if you did create a later alpha, I would not object if you did merge them!

If you have little patience, I'll backport the changes from #9722 to #9343, perhaps a little bit cleaner regarding the messages/graphics detection when no graphics support was requested (I'd like to keep that, i.e. not completely disabling it). In addition, we should catch illegal parameters to --graphic=

I don't know if you plan to make further changes to the PARI spkg.
comment:314 follow-up: ↓ 318 Changed 9 years ago by
From a first glance, the graphics detection in svn-12577 is cleaner, so the changes regarding that will be, too.
It's still not robust, and needs the same fixes as PARI 2.3.5, e.g.
- add
libstdc++
forplotfltk
, - handle libraries in
.../lib64
directories, - make sure FLTK include directory really exists,
- less annoying/clarified messages.
I haven't yet dealt with graphics support using Qt, which can break the build, too. I.e., the detection should be improved to either give an error earlier or disable Qt in case not all required components are available.
Most of the other changes (spkg-install
) still apply. In addition, there are superfluous tests of $?
at the end which I had not removed in 2.3.5.p4 (but added comments to remove them).

Try sage -docbuild reference html. Or look in the build log? I think that "make" does not build the docs (I may be wrong on that) but "make testlong" does, so it might be in the test log. Anyway, if you touch the offending files and do docbuild reference html it will presumable process them again.

Yes, they usually drown in the flood of Sphinx messages. (And even worse, Sphinx errors, too.)
I normally do e.g. grep -i warn dochtml.log
; grepping for "error" gives also lines with filenames containing it... ;-)
In case you've deleted the log, you have to touch the sources before doing make doc
, e.g. by ./sage -ba-force
, but that would cause a rebuild of all Cython files, and Sphinx would rebuild the whole reference manual from scratch. So better just touch the files mentioned in the warning messages, and do ./sage -b
, then make doc
, and carefully watch what rushes down the screen... ;-)

Well, installing Tachyon actually did not fail; I hadn't looked at the whole log.
It first tries a 32-bit build (prepending -m32

Leif,
you should open a ticket for this Tachyon problem. Put what info you have and cc me. I'd like to know of anything that adds -m32
as that sort of thing could screw up on any system, but particularly might screw up on systems were we add -m64
as we do on 64-bit Solaris builds. As you say, it's well off topic for this ticket, which is already very very long.

I guess John C. will know. I just wonder where we should address such issues; #8664 (with #5847 mandatory) is likely to go into the 4.6 series. (Though perhaps not 4.6.0, I'm not the release manager.)
What exactly might I know?

P.S.: Perhaps "just" some rare incompatibility of PARI to the new GMP/MPIR.
At least PARI 2.4.3.svn-12577.p4 passes its test suite with MPIR 2.1.1.

I think my guess (that you would know the code) was right. :-)
It's exactly the two long doctests you added at #8319 (as part of a regression doctest) that individually both segfault with MPIR 2.1.1 and ECM 6.3, in EllipticCurvePoint_number_field.height()
. Tagging these two doctests # not tested

OK, here's one way of testing this (perhaps). I made an input file for gp which computes that same example: http://www.warwick.ac.uk/staff/J.E.Cremona/pari-test.gp

The segfaults when doctesting happen in libgmp.so

The 32-bit Fedora machine segfaults at Q.height()

I was actually thinking (fearing) it was a Sage/Cython? bug, but can meanwhile reproduce the segfault with a GP script; going to sort out if it's PARI's or MPIR's fault.

If I understand correctly, this is a probably a Pari bug, which the Pari developers will hopefully fix. (It might not be of course - I'm not saying it is a Pari bug).
I would suggest that it would suggest it might be wiser to just add the bug fix to the Sage package, and not use the very latest svn checkout. That should reduce the chance of you getting any new bugs that might have been created. Since these are only svn snapshots, they can't be expected to be as stable as a well tested release.
Of course, it would be wise to ask the Pari developers too, but my general feeling is that it would be wise to make major changes now.

This wasn't meant as an offense; perhaps I should have written "... does not fully resemble what Sage does".

Yes, and that's what crashes with MPIR 2.1.1.
Sage's EllipticCurvePoint_number_field.height()
first calls self.has_finite_order()
, which in turn calls self.order()
, which uses PARI's orderell()
(deprecated, ellorder()
in the GP interpreter).

If the Pari upgrade is stalled over some issues, it might be worth considering putting the upgrade off for the a release. That would not slow the Pari upgrade, if the tickets merged had an almost zero probability of conflicting with the upgrade.
- #9766 is for example a ticket I reviewed, which is an update to an SPKG.txt file only.
That's an extreme example, but there must be other tickets which have a very small probability of affecting the Pari upgrade.
That said, I'm glad the 4.5.3.alpha2 has become available, and people are having time to test that without 4.5.3 being rushed out.

I lost track of who is doing what, so I don't know what (or who) we are waiting for. Or who will be the one to actually give it a positive review. Presumably what we want is that as soon as 4.5.3 is released the current prealpha of 4.6 is released as an alpha? What is to stop that happening now?

As far as I know, the only remaining issue is to port #9722 to #9343. I believe leif is working on that (If leif is unable to do it, I'm also willing to take care of that).
The large number of doctests without errors for sage-4.6.prealpha3 seem to indicate that the patches are fine.
I also would very much like somebody to have a look at #9400, because it also touches a lot of PARI code (the patch for #9400 has been included in 4.6.prealpha2 and 4.6.prealpha3).

Me, too. Also, it looks as if there was a lack of (other, "independent") reviewers, or at least people testing this. I still don't know if this has been tested on Cygwin, and, if there were any issues, if we should address them here. (Mike has provided a "follow-up" Lcalc to make it work on Cygwin; I'm not sure if that's the only required change w.r.t. prealpha3.)
Presumably what we want is that as soon as 4.5.3 is released the current prealpha of 4.6 is released as an alpha?
I actually expected a 4.5.3 release candidate rather than an alpha2, and 4.5.3 released earlier. 4.6.prealpha3 is still based on 4.5.3.alpha1, but as far as I know the only changes in 4.5.3.alpha2 are fixing numerical noise in doctests, and #9722, which I am porting to the new PARI; Mitesh will know better.
What is to stop that happening now?
Regarding this ticket, the only things I'm aware of are:
- preparing a PARI 2.4.3.svn-12577.p5 spkg, with the fixes from #9722, and in addition disabling the use of GMP internals by PARI by default (with an option to make PARI use them)
- fixing Sphinx warnings
- adding more documentation (strings) and doctests to (at least)
sage/libs/pari/gen.pyx
(cf. this comment and the corresponding attachment).
I don't know if further (new?) PARI functions should be wrapped; I only came across the deprecated orderell()
.
IMHO other things (e.g. Lcalc spkg improvements; I've commented on Mike's follow-up #9775) should be addressed during the normal 4.6 release cycle.
I guess an official 4.6.alpha would be tested by far more people, on a broader variety of systems. Same for 4.5.3 (final). If any problems arise with the latter, they should be fixed during the preparation of 4.6 alphas, not in our inofficial prealphas.
Replying to jdemeyer:
[...] port #9722 to #9343. I believe leif is working on that.
Yes. Unfortunately the MPIR 2.1.1 issue took too much of my time and resources; I now consider it (more or less) "resolved", and continue the work on the PARI 2.4.3.svn-12577.p5 spkg.
The large number of doctests without errors for sage-4.6.prealpha3 seem to indicate that the patches are fine.
Hopefully. It might also indicate a lack of (appropriate) doctests... ;-)
(E.g., despite the obvious bug in MPIR 2.1.1, Sage 4.5.3.alpha2 and 4.6.prealpha3 - with PARI not using GMP internals - both passed all long tests on two systems with it. There have been similar cases in the past.)

I'm assuming you refer to the "GMP internals" mentioned in #9837? Note that these are actually documented GMP internals, so it's not as bad as it sounds. So I would prefer not to touch that code and leave PARI using documented GMP/MPIR internals as it is.

I'll release a 4.5.3.rc0 later today (or possibly, tomorrow) which, if there are no new blockers, will become Sage 4.5.3 a week later. Soon after that, I'll start merging positively-reviewed (PR) tickets (listed at reports {11} and {32}) into 4.6.alpha0.
If the essential PARI upgrade tickets are
- PR at that time, I'll merge them (and perhaps other PR PARI-related tickets) into 4.6.alpha0 and leave the other PR tickets for 4.6.alpha1 (or later).
- Not PR at that time, I'll merge other PR tickets into 4.6.alpha0 and leave the PARI tickets for 4.6.alpha1 (or later).
Either way, I don't plan to release Sage 4.6 (== 4.6.0) until it's sufficiently stable.

I think that would be a bad idea. It's difficult to say for sure without knowing what was changed in all 11 different svn snapshots, but given these are only snapshots with little testing, I think you have a reasonable probability of hitting another bug.

The prealpha4 passed ptestlong
on Ubuntu 10.04 x86_64 (Core2) and Fedora 13 x86 (Pentium 4 Prescott), too. Installing the package with SAGE_CHECK=yes
also works.
Tuning now doesn't give an error on the former, but still hangs on the latter (see previous posts).
The patch to tune.c
from svn 12588 is a one-liner btw.

Having produced a tar file for people to test, it would have been wise to get some more feedback before setting it to positive review.
I'm going to build it now on OpenSolaris. Nice thing about that is that's it's very quick. Downloading the tarball is less so!

If so, you could try reinstalling the PARI package with PARI_EXTRA_OPTS="--graphic=auto"
or e.g. X11
; best once with X11 development files present, and once in addition without (a functional) xmkmf
. (I don't know what X11 [development] packages OpenSolaris provides.) :-)

Took more than three times longer than usual for me yesterday...

Is the
PARI_EXTRA_OPTS="--graphic=auto"
just an environment variable I should set? If so, that will be trivial. I'm actually building two copies of Sage at the minute on this machine, so its under a heavy load, but I'll try this later
I see your point elsewhere about Qt. I have some Qt libraries on here, which come as part of Mathematica. Not sure if I should set LD_LIBRARY_PATH to include them. Let me know.

Yes, that's passed (verbatim) to PARI's Configure
by Sage, so do
export PARI_EXTRA_OPTS="--graphic=X11"
(--graphic=auto
will pick X11 if it's found, otherwise try FLTK and Qt.)

I don't think Mathematica ships with Qt development files... (But there should be such OpenSolaris packages. If you choose X11, PARI will just use "plain" X11.)
W.r.t. #9603, my main machine is still headless... :/

It doesn't always hang at exactly the same point (of output), but this might simply be due to unflushed buffers; the point where it "stops" only differs by some lines (different size / threshold for the same function, when attempting to tune REMIIMUL_LIMIT
if I understand correctly). When I interrupt the tuning from within a Sage build with Control-C, I get cores dumped. Plain PARI seems to catch the signal (properly) and exits with
^C *** user interrupt. *** Error in the PARI system. End of program.
but continues compilation (which of course fails).

On a Pentium 4 (Northwood), PARI self-tuning works, and make test-all
apparently passes all tests except those few that require extra data files, though the self-test also ends with
+++ [BUG] Total bench for gp-sta is 585030 +++ [BUG] Total bench for gp-dyn is 592375 ...
I'm not sure what that's intended to mean.
This is with gcc 4.2.1 and GMP 4.3.2 though.

This means that some self-tests failed. Normally you can see which tests failed by looking at the last lines of the output of make test-all
.

Yes, and these are exactly the six (IIRC) tests that need extra data; I verified that by looking at the diffs. I don't know what "total bench" and the numbers express. (It's near to, but not the seconds the tests took... ;-) )

Oh, it might be the (CPU) time in ms the test(s) took (sum about 20 minutes), but the "[BUG]" next to it is quite irritating.
Btw, tuning also works on the Pentium 4 Prescott with GMP 4.2.4 and gcc 4.3.3, so perhaps there's a bug in GMP; a bug in gcc (4.4.4) is IMHO rather unlikely.

But there another test fails (in linear-{sta,dyn
}) which is not due to missing data files; perhaps numerical noise... (Both diffs are identical.)

This shouldn't happen, can you make a new ticket and post the the linear-sta.dif
?

prealpha4 worked fine for me on 32-bit and 64-bit linux.
Now that 4.5.3 has been released it would be great of we could get this as the beginning of an actual 4.6.0 series.

What do you see as the window for merging changes into 4.6? I'd like to finish some significant changes to fast_callable, but don't think they should be introduced in a point-point release. 4.6 sounds like a good release for the changes.
Up to three weeks. I think there will be three alphas for the 4.6 cycle, since I'll focus on the PARI upgrade (#9343 and related tickets) for 4.6.alpha0. For alpha1 and alpha2, I plan to merge most of the other positively reviewed tickets waiting at reports 11 and 32:
http://trac.sagemath.org/sage_trac/report/11 http://trac.sagemath.org/sage_trac/report/32
Of course, how it really goes will depend significantly on build and test reports. [...]

It should, since test -e ...

Dave, what shell is /bin/sh

/bin/sh
is a borne shell, but it is not POSIX compatible, since to make it POSIX compatible would break backwards compatibility in Solaris.
There are however other shells, such as /usr/xpg4/bin/sh
which are POSIX compatible. Hence there is a need to work around the Solaris shell /bin/sh
, and do not assume that it is POSIX compatible, since it is not.

NOTE: According to http://pari.math.u-bordeaux.fr/packages.html, there are now two seadata tarballs; we'll have to make one standard, and one optional.
