pari-2.2.2.alpha released |
Hi, I've made a snapshot of my current sources as pari-2.2.2.alpha. You can find it at ftp://megrez.math.u-bordeaux.fr/pub/pari/unstable/pari-2.2.2.alpha.tgz This in an ALPHA version, so the usual caveats apply: it is unstable, probably contains severe bugs, and is not properly documented. It is definitely NOT adequate for site-wide installations. This snapshot fixes a number of bugs [some of which introduced in the previous one], but nothing major. I'm releasing it because it contains no critical bug I'm aware of, and the last snapshot is already about three months old. Have fun, Karim. P.S: The Changelog: Done for version 2.2.2 (released 10/01/2001): Fixed 1- qfbred(Qfb(4, 17, 18)) --> SIGFPE 2- broken compilation in arith.c when CC != gcc 3- nfhilbert (local case pr | 2) expected POLMOD argument without check 4- poldegree(P, t) slow when t != varn(P), and may not work in library mode 5- polrootspadic only worked when leading coeff was a unit 6- paddicappr was very slow (esp. when p was large) 7- Configure: check for 'double endianness' [used for double --> t_REAL conversion]. Previous check was failing on ARM architecture. 8- forsubgroup state not properly restored after ^C 9- libpari.so included symbols from libc without linking it explicitly (Debian requirement, and cleaner anyway) 10- recent pdftex failed to compile users.tex (\pdfannotlink undefined) 11- !nf.sign[1] was parsed as (!nf.sign)[1] 12- matrix(0,1) --> "identical index variables in matrix" [from 2.2.1 F48] 13- bnfinit could miss some relations in the "small norm" phase 14- x % y incorrect when y < 0 inexact (2 % -3. --> -1.) 15- typo in gcdreal (result < 0) [introduced in 2.2.1] 16- some obscure problems in rnfkummer 17- not enough GC in hnflll 18- sqrt(25 + O(2^5))^2 - 25 = O(2^4) 19- not enough GC when writing a t_PADIC 20- user member functions were very slow (unnecessary copy) 21- cd Oxxx; make -j4 bench ran things in the wrong order 22- poltchebi, pollegendre gave bogus output for negative degrees 23- possible SEGV or oo loop in polrootsmod when p not a prime 24- nfnewprec(bnf) could change bnf.gen (due to round-off errors) 25- SEGV in gcd(x,y) when operands have coeffs of the form Mod(t_INT,t_POL) 26- not enough GC in poldivres (= t_POL % t_POL) 27- issquare(Mod(3,27)) = 1 [from 2.2.1 C 10] 28- [BUG] message in 'elliptic' bench [made polroots more canonical] Changed 1- allow compressing *.dvi files for the online help system 2- index bound was restricted to MAXLONG in subgrouplist. Made it a GEN 3- try to guess correct precision earlier in polgalois/polroots 4- allow GP pointers to 'matrix components', e.g issquare(25,&x[i][j]) 5- changed assignment semantics to make it closer to C: x = y understood as (evaluate Y:=y, then set x:=Y), e.g i=0; i += (i=2) sets i to 4 (was 2) 6- output VECSMALLs as 'Vecsmall([...])' 7- more efficient polcoeff [also: made it independent of MAXVARN] 8- retuned bnfinit (let subfactorbase increase further): setrand(1);bnfinit(x^4 + 1159*x^2 + 335241) would never finish. 9- specified precisely lex() [see manual]. Now: lex([0,0],[0]) = 1 (was -1), lex(0,[0]) = -1 (was 0) 10- allow factorback(x, e) for prod x[i]^e[i] 11- don't store empty lines in history [cf 2.2.1 F57] 12- extend x \ y, x \/ y and divrem(x,y) XR 13- improvements in bnrstark (try harder to find modulus, need less memory) 14- global(x): ignore if x already global (used to raise a warning) BA 15- install: add RTLD_GLOBAL to dlopen flags [so that symbols can be used in other .so] 16- removed hack in gp_init.c [used "constant default args" to call print0] Added BA 1- New function 'vectorsmall'. 2- allow setting variable in divrem 3- GP operator #l for length(l) 4- a warning in zsign ("increase precision?") when dubious result 5- Montgomery reduction (only used in powmodulo() for now) 6- [experimental] basic tuning utilities (src/test/tune.c) [make tune] -- Karim Belabas Tel: (+33) (0)1 69 15 57 48 Dép. de Mathematiques, Bat. 425 Fax: (+33) (0)1 69 15 60 19 Université Paris-Sud Email: Karim.Belabas@math.u-psud.fr F-91405 Orsay (France) http://www.math.u-psud.fr/~belabas -- PARI/GP Home Page: http://www.parigp-home.de/
