pari-2.2.12 released |
Dear PARI enthusiast, I would like to announce the release of pari-2.2.12-BETA. The sources and a pre-compiled binary for Windows can be obtained through the address http://pari.math.u-bordeaux.fr/download.html This is now a BETA release of the PARI/GP system, since the code is stable enough for widespread testing. Please test and report problems in 2.2.12, we need your help ! See http://pari.math.u-bordeaux.fr/Bugs/ for how to report problems. Have fun, Karim. P.S: The Changelog (cleanup and minor bugfixes). Done for version 2.2.12 (released 24/01/2006): Fixed 1- incorrect detection of EditLine library 2- issquare(Mod(2,9)) --> 1 [ should be 0 ]. Implicitly assumed v_p(N) odd for all primes divising the modulus N. BA 3- poltschirnhaus(ffinit(2,4)) could return 0. BA 4- Configure -a did not propose fltk and Qt as graphic engine. 5- g()=local(x;f) -- oo-loop [#352] 6- charpoly( Mod(a, b) ) --> wrong result when 'a' is not a t_POL or t_INT. 7- \p2051 log(exp(-1)) --> printing bug [#357] 8- bad argument checks in qfrep() / qfminim() [#359] 9- fix mkintn to work as documented (even when leading word is 0) BA 10- [Linux] gp only accepts one SIGINT in batch mode [#251, #370] (initial patch JD). 11- contfrac(5/3.) was wrong: [1,2] instead of [1,1,2]. For a t_REAL x, when the last partial quotients of a lower and upper bound differ by 1, choose the one associated to the digits of x (followed by infinitely many 0s) unless it was too small and the next partial quotient was 1. [#371] 12- bnfisintnorm: results could have a wrong sign [#372] 13- isprime(N,2): oo loop if N is a perfect square 14- \p n was limited to a value ~ 10 times smaller than the actual limit BA 15- qfbsolve fix 2.2.11-F86 was not sufficient. 16- (1 + O(2))^2 was less precise than sqr(1+O(2)) 17- in the extended help pager, typing ' ' then \n would skip one page [#375] BA 18- config/has_stat.c didn't work with g++ 19- charpoly/minpol(Mod(a,T)) was only monic if T was. BA 20- 'make install' did not work if 'prefix' contained spaces 21- has_dlopen always compiled in on Mac OS X, even if present in libc 22- unsafe handling of t_QFI/t_QFR (setsigne) [#384] 23- idealaddtoone didn't handle zero ideals [#386] 24- workaround a bug in g++ version 3.4.1 (Mandrakelinux 10.1 3.4.1-4mdk) infinite loop on factor(41093858855767145965571) 25- constlog2() was not restartable [ no way to set glog2 = NULL ] 26- sloppy arg check in ellchangecurve [#388] 27- [internal] gprec_w reduced the accuracy of real 0s [#396] 28- wrong arg check in matsolve [#400] 29- minpoly([;]) --> SEGV 30- y*x^3/( 1+x+x^2 +O(y)) -> gerepile error [#403] 31- poldivrem didn't handle properly multivariate polynomials [#402] 32- insufficient accuracy in ellheight --> singular curve, SEGV [#404] 33- [MacOS X + fltk] installed gp binary couldn't use hi-res graphics (resource fork not copied) IZ 34- [2.2.9-A20] -fno-strict-aliasing not supported in older gcc 35- heapsize reported by getheap() were wrong (overestimate). 36- gerepile error in nfgaloisapply [#408] 37- wrong results in bessel functions at non-integer indices (typo in isint(t_REAL) ) [#409] Changed 1- speed up prime() by using checkpoints. 2- allow lists with vector entries in listsort (use lexsort) 3- allow vector of points in ellisoncurve() 4- tunings in quadclassunit (#298 / #355) 5- [Configure:] take CPPFLAGS into account 6- 'int' C type is now reserved for -1/0/1 values. Use 'long' otherwise. 7- Fl_inv and Fl_div now raise an error when divisor not invertible [ used to return 0 ] 8- removed the threshold that prevented exponent overflow in exp(-10^10) and returnd 0. instead [ either return correct digits or raise an exception ]. VL 9- honor C_INCLUDE_PATH in Configure (for get_readline) 10- [readline] remove old hack bypassing a bug in readline-2.0 [ did not release SIGINT ]: useless nowadays, and used deprecated functions. 11- export combine_factors [ needed by giac ] 12- do not alias labs to abs in paricom.h 13- randomize polredabs() to improve bound on difficult fields, e.g. f(k) = { p = polcompositum(x^6-3*k^3,x^6-3*k^3)[4]; polredabs(poltschirnhaus(poltschirnhaus(p)),16) } for k = 2, 5, 6, 8, ... 14- try more names in 'pari_unique_filename' (26^2 instead of 26)) 15- remove GCC_INLINE from CFLAGS. Define DISABLE_INLINE or DISABLE_VOLATILE to prevent the compiler from inlining or using the 'volatile' keyword 16- let paripriv.h include parinf.h 17- rename 'prec' -> 'precreal' [ from paripriv.h ] BA 18- define INLINE to 'inline static' for C++ compilers also 19- rename polx -> pol_x, polun -> pol_1 20- make hell, hell2 static to elliptic.c 21- rename decomp -> Z_factor, decomp_limit -> Z_factor_limit 22- rename wf -> weberf, wf1 -> weberf1, wf2 -> weberf2 23- make incpos / incneg static 24- export setseriesprecision, setrealprecision BA 25- make pari restartable 26- [initialization of GP hashtables] remove the 'module' structure, simplify pari_addfunctions, plug helpmessages in initializing entree arrays. 27- rename err -> pari_err, pariputsf -> pariprintf 28- rename rnfhermitebasis -> rnfhnfbasis 29- forbid t_STR, t_VECSMALL and t_LIST in gvar. 30- cleanup mpqs use of temporary files 31- pari_unique_filename now MT-safe, returns a malloc'ed buffer. 32- default() now always returns the value of the (possibly changed) default. No need for a flag anymore. The construction default(def,,1) is still valid but deprecated (the flag is ignored). 33- increase default accuracy in ellinit() when curve has large coefficients [ avoid large relative error on periods, #404 ] 34- qfminim(,,,0) often gives wrong results for matrices with large entries. Test whether rounding errors occur and abort if so [#407] 35- qfminim(x,b,m,flag): b and m are now optional. Allow omitting b (formerly b=0) if flag = 2 also. 36- eval("1a") is now '1' again (was "a" since 2.2.10) Removed BA 1- gnuplot graphic engine (complicated, did not work from gnuplot-4 on) 2- has_sigrelse.c & has_sigsetmask.c [ deprecated, unused after C-10 ] 3- src/desc/Makefile 4- log2old ( = 2atanh(1/3) ) 5- src/desc/gen_help BA 6- obsolete macros INIT_JMP/INIT_SIG Added 1- library function ellisoncurve() BA 2- library functions related to sorting: gen_sort_aux, gen_search_aux, vecsmall_indexsort 3- functions strtoi, strtor BA 4- function minpoly() 5- function zeromatcopy() BA 6- support for GNU/kFreeBSD and other GNU userlands. 7- document ZY_ZXY_rnfequation and ZY_ZXY_resultant 8- function pari_warn() used instead of pari_err() for warnings 9- function pari_add_function, pari_add_module 10- doc/develop.tex 11- library function uisprime, uissquarerem, Z_issquare, Z_issquarerem 12- library function pari_unique_dir 13- library function gp_default 14- library function rowcopy (GP2C) 15- library function traverseheap -- Karim Belabas Tel: (+33) (0)5 40 00 26 17 Universite Bordeaux 1 Fax: (+33) (0)5 40 00 69 50 351, cours de la Liberation http://www.math.u-bordeaux.fr/~belabas/ F-33405 Talence (France) http://pari.math.u-bordeaux.fr/ [PARI/GP]
