2180:
2181: Fixed:
2182: 1- rare bug in gadd (PADIC + PADIC) which caused one of the arguments

2184: 2- typos in refcard
2185: 3- galois.c still couldn't compile on the HP (_INCLUDE_POSIX_SOURCE)
2186: 4- introduced in 2.0.2: item 14 used gexpo incorrectly (bnfinit sometimes
2187: did not give units it could have computed)
2188: 5- replaced INFINITY by pariINFINITY in rootpol.c (cancels Warning on OS/2)
2189: 6- on OS/2, target ../gp-$dft in o.xxx/Makefile could not be built
2190: (extraneous $exe_suff)
2191: 7- command line switches so that one can enter them with or without white
2192: space (new function read_arg in gp.c)
2193: 8- setdcolors so that it can't unset disable_colors if we are under emacs
2194: 11- random did not check its argument correctly (random(2^32) was accepted)
2195: 12- b=10; for(a=1,b, b=2) exited immediately, whereas the upper bound is
2196: supposed to be evaluated only once
2197: 13- reorganized the error recovery system (initially because errpile could
2198: cause SEGV on Linux systems)
2199: 14- typo. problems in doc and refcard (interletter spacing in $nfz$...)
2200:
2201: Changed:
2202: 1- Reorganized Makefile.SH: extraction twice as fast
2203: 2- pari.menu and pariemacs.txt rewritten, pari.el updated
2204: 3- expanded the man gp.1 to mention command line switches
2205: 4- the implied input from non-interactive input command (like extern and
2206: read) does not go into the GP history (%x) anymore (it never went into
2207: readline's). The final output (value of last expression evaluated) of
2208: course still does!
2209: 5- updated chapter 5 of the User's Manual (removed obsolete information)
2210:
2211: Added:
2212: 1- better settings for handling the Meta key under readline in
2213: examples/Inputrc

2219: 5- overloaded the "." (member) operator to concatenate as strings if LHS is
2220: a string
2221: 6- .gprc accepts some limited preprocessing directive (#if READL and
2222: #if EMACS (and #ifnot as well)). Updated lib/gprc.default to reflect the
2223: changes
2224:
2225: Removed:
2226: 1- some unused, undocumented functions (allocatemem(), checksqid())
2227: made static some other (op_ReIm)
2228:
2229: ===========================================================================
2230: Done for version 2.0.2.alpha (released 15/12/1997):
2231:
2232: Fixed:
2233: 1- typos in the documentation for the random() function
2234: 2- removed an extra -emacs flag in pari.el
2235: 3- decodefactor was incorrectly remembered by whatnow (it's factorback now)
2236: 4- test mode did not prevent all prompt expansion (==> bug in make test)
2237: 5- gphelp stopped abruptly when meeting a cross-referencing macro
2238: 6- zetainit now aborts cleanly when disc. too big (caused memory fault)
2239: 7- exceedingly rare bug in the printing of real numbers (missing decimals)
2240: 8- too early rounding in polroots which in rare cases made GP think some
2241: error had happened
2242: 9- text overflowed the manual pages (and tutorial) on non-A4 paper
2243: 10- polred incorrectly assumed that nf arguments were totally real (in a non
2244: critical part: that just led to some unnecessary computations)
2245: 11- polred(f,2) could try to overwrite universal integer gzero
2246: 12- check if we are using GNU as or GNU ld in Configure
2247: 13- empty -R argument to $CC when building GP without graphics (==> link
2248: failed)
2249: 14- bnfinit acts sensibly when fundamental units are too large (before:
2250: "overflow in R*R")
2251: 15- cleaned up buch2.c (removed ideallllredpart1, removed gerepile in
2252: class_group_generators(), not_given now called from getfu)
2253: 16- nfgaloisconj(...,2) was unusable (tried an illegal multiplication)
2254: 17- is_totally_split was very inefficient (==> nfgaloisconj was very slow)
2255: 18- some unimportant typos (gexpo) in polgalois
2256: 19- compiling without readline gave a Warning in gp.c (already_hist)
2257: 20- some make programs don't like $< (suppressed from doc/Makefile)
2258: 21- ellap sometimes assumed wrongly that coeffs of the curve were integers
2259: 22- flag 0 and 1 in ellap had been mixed up
2260: 23- print an extra \n before an error message if last output did not
2261: include it
2262: 24- component(any non recursive type) gave a SEGV
2263: 25- suminf / prodinf / prodeuler assumed they treated a real expression
2264: 26- lindep / algep had problems with numbers having a rational component
2265: 27- last significant digits of bessel* and hyperu were wrong (now only the
2266: last one is)
2267: 28- expi now returns a long as documented (expi(gzero) returned 0 on 64-bit
2268: machines!)
2269: 29- g++ could not compile libpari.a (casts missing, extraneous extern "C",
2270: faulty inline, etc.)
2271: 30- cleaned up the enums in gp.h
2272: 31- incorrect target veryclean in doc/Makefile
2273:
2274: Changed:
2275: 1- '_' is now valid in GP identifiers
2276: 2- removed subsections from table of contents. pages in the manual are now
2277: numbered consecutively
2278: 3- gexpo now accepts exact 0 arguments (return -HIGHEXPOBIT)
2279: gexpo for complex numbers now return max(gexpo(Re), gexpo(Im))
2280: 4- parts of lib/gprc.default
2281: 5- the second argument of subgrouplist is now optional
2282:
2283: Removed:
2284: 1- buggy label/goto functions
2285: 2- (now unused) error messages: labeler, gexpoer2
2286: 3- _ as shorthand for conj()
2287: 4- (useless, undocumented) function gnormalize
2288: 5- some files in the lib directory (functions, gp)
2289:
2290: Added:
2291: 1- some files in the lib directory (README, pari.xbm, xgp)
2292:
2293: ==============================================================================
2294: Done for version 2.0.1.alpha (released 29/11/1997):
2295:
2296: Fixed:
2297: 1- multiple factors forgotten when factoring univariate pols over Z
2298: 2- extraneous modifications of the random seed (period of random
2299: generator was ridiculously small for some buchxxx functions). Change
2300: the bench results (in a non essential way)
2301: 3- bad terminal size determination
2302: 4- aliases incorrectly killed (possible SEGV)
2303: 5- incrementing/decrementing array elements with the (valid) syntax
2304: v[i]++ / v[i]-- caused a weird error message
2305: 6- subgrouplist() could end up by a SEGV on Linux systems
2306: LG 7- on HP-UX, flag -Aa not taken into account in Configure (caused it to
2307: fail on has_TIOCGWINSZ.c)
2308: LG 8- added a missing #define _INCLUDE_POSIX_SOURCE in galois.c
2309: (7 & 8 independently fixed by OV)
2310: GN 9- the script examples/cl.gp called vecconcat() instead of concat()
2311: GN 10- make install-sta rebuilt gp-sta unnecessarily
2312: GN 11- many, many typos in the tutorial
2313: 12- tu / fu applied incorrectly to a bnfclassunit
2314: 13- bnfclassunit did not output a valid object (matrix whose elements were
2315: rows instead of columns)
2316: 14- conversion bug from t_QUAD to t_REAL/t_COMPLEX
2317: 15- off-by-1 error in the history recovery after an error
2318: 16- in fprintferr() (debug messages), embedded %Z did not work correctly
2319: 17- rnfequation over Q yielded a SEGV
2320: 18- string() in compatibility mode corrupted the stack
2321: 19- it is now safe to have colours in prompt and input line under readline
2322: 20- default colours restored upon exiting
2323: 21- default colors in lib/gprc.default used 0 instead of -1 for "no color"
2324: 22- psi and lngamma could give wrong results when the argument was not real
2325: 23- the make test-graphic bench was missing a newline
2326: 24- Pol(break) gave a SEGV
2327: 25- x=1; Pol(1) gave a stupid error message
2328: IZ 26- tutorial.tex was unnecessarily rebuilt
2329: 27- typos in ggcd (cases nobody will ever access: gcd of a non-reduced
2330: LG fraction with an intmod, etc.)
2331: LG 28- incorrect handling of integrals of vectors
2332: 29- gcd of polynomials with non-exact coeffs gave stupid results (they are
2333: still often wrong, since the mathematical notion is rather imprecise)
2334: 30- typos in rnfkummer (incorrect flag handling)
2335: 31- typo in idealpowprime (negative exponent gave wrong denominator)
2336: 32- multiplication t_COMPLEX x t_COMPLEX used 4 mult. instead of 3
2337: 33- some modular functions (j, f, f2) rewritten to take advantage of new eta
2338: function (trueta)
2339:
2340: Changed:
2341: 1- ?? (gphelp) starts in detex mode (-d) from a console window. tmp files
2342: now placed according to the $TMPDIR environment variable (in /tmp by
2343: default)
2344: 2- /usr/local/lib/pari/data is a better place for the Galois resolvents
2345: (which are not included yet in the standard distribution)
2346: 3- The example for prompt in gprc.default to discuss escape sequences under
2347: readline
2348: 4- Configure now starts by searching the toplevel directory for a temporary
2349: readline installation
2350: 5- The output of default(colors) was confusing. It is a string now
2351: 6- third argument of polinterpolate can be arbitrary and is now optional
2352: ("x" by default) (it had to be numeric)
2353: 7- directory configure renamed config, some of the Makefiles in there as
2354: well (to avoid confusion)
2355: 8- the low_stack macro to facilitate dynamic stack expansion
2356: 9- if, back to GP main loop, the last command was a print1(), output an
2357: extra newline. This way the prompt is guaranteed to be anchored on
2358: column 1 (suppresses a readline display bug as well)
2359: 10- Due to 9, pari.el now supposes the prompt starts in col. 1
2360: 11- Better handling of version numbers (LG)
2361: 12- decodefactor() renamed to factorback()
2362:
2363: Removed:
2364: 1- The (unused, undocumented) Malloc_Procs functions and macros
2365: 2- The (now unused) error message numvarer
2366: 3- some (useless, undocumented) targets in the top Makefile
2367: 4- (useless, undocumented) function polgcd()
2368:
2369: Added:
2370: 1- This file !
2371: 2- new flags -ch, -cb, -cu (colour support) to gphelp (see its header)
2372: IZ 3- OS/2 (+ enough tools...) supported by Configure
2373: 4- file examples/Inputrc (example of .inputrc for readline)
2374: 5- Weber f1 function implemented
2375: 6- Karatsuba multiplication t_REAL x t_REAL (development code, not used by
2376: PARI yet). Test it with install if you wish
