pari-2.0.9.alpha update |
Hello all, yet another update (alpha, yes, see below). ftp://megrez.math.u-bordeaux.fr/pub/pari/unix/pari.tar.gz The diff file with previous version 2.0.8.alpha can be found at ftp://megrez.math.u-bordeaux.fr/pub/pari/2.0.8.a-2.0.9.a.gz This update was scheduled to be a beta, but 1) some bugfixes had to hit highly sensitive areas of the code. 2) we received many interesting contributions/improvements. So I decided to postpone the beta by two weeks and to release another alpha snapshot in the meantime. Please crash-test this version with your favourite applications, it _is_ the last one of the alpha cycle. Enjoy ! Karim. P.S: The MPQS implementation kindly adapted from the LiDIA code by Thomas Papanikolaou and Xavier Roblot and announced by Thomas on this list, is still not too well integrated within PARI (it does not communicate well with PARI's ECM, and is thus very inefficient when "small" factors survive the trial division stage; it works well on balanced numbers). I made it available through the new (and hopefully temporary) function factorint(). Hopefully, a patch will be available soon... P.S2: The Changelog: =========================================================================== Done for version 2.0.9 alpha (released 16/06/98): Fixed 1- typo in qfbhclassno (SEGV when result in (1/3)Z) 2- too much memory allocated in factmod /factcantor (use clones) 3- removed the -DREADLINE_LIBRARY hack, use <readline/readline.h> and not <readline.h> 4- version 2.0.8 did not compile with readline 1.* 5- after gaffect(0, padic), padic was unsuitable for further gaffect 6- length(a string) gave number of non code words, not string length. 7- factorpadic(polynomial of degree one) did not convert coeffs to padics 8- reduction mod p^r forgotten in gaffsg(s,t_PADIC). 9- default(realprecision,,1) did not return # significant digits. 10- typo in nfmodprinit (return x instead of 1-x) 11- matinverseimage did not check its arguments 12- mathess([;]) --> SEGV 13- matid(-100) --> SEGV 14- mateigen([;]) --> SEGV 15- matmultodiagonal([;],Mat(1)) --> SEGV 16- vecextract([;],"..") --> SEGV 17- introduced in 2.0.8 (Added 3-): aliases/user function + <TAB> ==> SEGV GN 18- (t_RFRAC) ^ t_INT took an unreasonable amount of time. 19- prevent quick succession of ^C from corrupting memory in recover() 20- hyperu could enter an infinite loop due to round-off errors XR 21- matadjoint(Mat(n)) returned Mat(n), not Mat(1) 22- matadjoint([;]) returned [[;]] (???) 22- wrap some long error messages XR 23- inefficiencies in rnfpolredabs XR 24- nffactor (wrong format for discriminant computation + problems with unseparable polynomials + compute disc only once). HC 25- typos in kummer.c GN 26- check environment variable LINES, not ROWS 27- introduced in 2.0.7 (Fixed 7-): lift(Mod(O(2^0)*x, x^3 - 2)^4) was a zero polynomial with non-zero sign (=> pb when normalizing in poldivres) 28- timer always returned 0 if times() was used (e.g linux-alpha) 29- kill'ing the argument of a user function corrupted the function. 30- make clean did not remove pariinline.h 31- incorrect memcopy in identifier, case 's' (removed * sizeof(long)) 32- online help for ?. (nf.nf does not exist) 33- lisseq0: gnil not respected after break/next. avma=av too brutal after return. 34- ellwp assumed precdl > 3 35- under emacs, \c + hit return froze emacs (Emmanuel Kowalski) 36- (f()= f()=x); f; didn't set f properly GN 37- comments in anal.c 38- qflllgram([;]) --> SEGV 39- no online help for bernfrac 40- from 2.0.6 (Fixed-8): in padicff2, forgot to raise ideal to power e Changed 1- improved (trivially) gneg (case t_INTMOD), gtopoly 2- use macro is_bigint() instead of tests (ulong)x[2] < VERYBIGINT (led to typos as in Fixed-4 in 2.0.8) 3- improved poldivres by replacing many gsub by 1 gneg + many gadd 4- in pvaluation check for small integer 5- internal function rnfelement_*mod (prhall=NULL instead of gzero) 6- improved mathess 7- added error message "inconsistent data in" in parierr.h 8- gpui[gs] renamed to gpow[gs] GN 9- improved probable-primality tests ('end matching') 10- moved pseudo primality and ECM stuff into ifactor1.c GN 11- raise to an integer power using left-shift binary (new functions powi and powgi) 12- add some details in the online help headers GN 13- nextprime, precprime now accept real arguments TP 14- improved the alpha micro kernel (addllx and subllx) 15- simplified poltschirnaus 16- cleaned up identifier(): #ifdef __hpux__ + call_fun() modified 17- taylor() improved (one gerepile removed) 18- unified the treatment of zero series 19- gerepilemany faster and more efficient memory-wise (copy to heap first) GN 20- improved stack checking in lllgramall Removed 1- global variable defaultpadicprecision. 2- function compute_prhall (nfmodprinit is better) 3- function [g]pseudopremier (miller[rabin] better) Added 1- function egalii 2- support for cygwin32 in Configure (Andy Stubbs) 3- new function gunclone to delete a clone (killbloc should be used by the analyser only) 4- comments in anal.c TP+XR 5- new function factorint(), using MPQS (_experimental_). -- Karim Belabas email: Karim.Belabas@math.u-psud.fr Dep. de Mathematiques, Bat. 425 Universite Paris-Sud Tel: (33 1) 01 69 15 57 48 F-91405 Orsay (France) Fax: (33 1) 01 69 15 60 19 -- PARI/GP Home Page: http://pari.home.ml.org
