Category: Lisp Core Group: None Status: Open Resolution: None Priority: 5 Submitted By: Raymond Toy (rtoy) Assigned to: Nobody/Anonymous (nobody) Summary: subres gcd wrong Initial Comment: Here is an example of where subres produces the wrong result but spmod is ok. p:(x^3+1)/(2*x^5+2); q:(sqrt(5)+5)/(20*x^2+(10*sqrt(5)10)*x+20); gcd:subres; ratsimp(p+q); => ((sqrt(5)+5)*x^32*sqrt(5)*x^22*sqrt(5)*x+sqrt(5)15)/(80*x^5+80) But now see what happens with spmod: gcd:spmod; ratsimp(p+q); => ((sqrt(5)+5)*x^5+(5*sqrt(5)5)*x^4+10*x^310*x^2+(5*sqrt(5)+5)*x +sqrt(5)15) /(20*x^7+(10*sqrt(5)10)*x^6+20*x^5+20*x^2+(10*sqrt(5)10)*x+20) factor(%): => (sqrt(5)*x^5+5*x^55*sqrt(5)*x^45*x^4+10*x^310*x^2+5*sqrt(5)*x+5*x +sqrt(5)15) /(10*(x+1)*(2*x^2sqrt(5)*xx+2)*(x^4x^3+x^2x+1)) Maxima doesn't notice but the numerator has the factor 2*x^2sqrt(5)*xx+2: divide((sqrt(5)*x^5+5*x^55*sqrt(5)*x^45*x^4+10*x^310*x^2+5*sqrt(5)*x+5*x +sqrt(5)15), (2*x^2sqrt(5)*xx+2)); => [((sqrt(5)+5)*x^32*sqrt(5)*x^22*sqrt(5)*x+sqrt(5)15)/2,0] So the final result of ratsimp is ((sqrt(5)+5)*x^32*sqrt(5)*x^22*sqrt(5)*x+sqrt(5)15)/2/(10*(x+1)*(x^4x^3+x^2x+1)); Notice that the numerator matches the numerator for the subres result, but the denominator is off by a factor of 4!

Category: Xmaxima Group: None >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Closing xmaxima issues "kill TERM 1" Initial Comment: At least for my particular setup, xmaxima has a very unfortunate behaviour at shutdown. I'm running a Linux x86 box, KDE 3.4, Tcl 8.4, maxima 5.9.1. Somehow, it seems that "pid" is set to 1 in line 13603 of xmaxima. This sends a kill TERM to every process it can, wiping out my login session and any associated jobs running. If run as root, it wipes out every logged in session and every running daemon. A sanity check on that parameter might be in order before issuing the kill on Linux.  >Comment By: Robert Dodier (robert_dodier) Date: 20060516 21:11 Message: Logged In: YES user_id=501686 Fixed by modifying the #+clisp version of GETPID in src/server.lisp (r1.10) so that it calls PROCESSID. Bug not observed in Xmaxima from Maxima 5.9.3 / Clisp 2.34, and referredto Redhat Bugzilla item is closed. Closing this report as fixed.  Comment By: Kevin Kofler (kevinkofler) Date: 20050922 20:53 Message: Logged In: YES user_id=573515 Please look at the Red Hat bugzilla #168451, they have pretty much tracked it down. Looks like it depends on the LISP runtime (Fedora uses clisp). https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=168451  Comment By: Robert Dodier (robert_dodier) Date: 20050922 14:38 Message: Logged In: YES user_id=501686 To the anonymous person or persons adding comments to this item: can you PLEASE PLEASE PLEASE login or leave an email address or something? PLEASE. I would like to fix this bug  really I would  but I can't reproduce it, and therefore I need your help to track down what's going on here.

Robert Dodier  Comment By: Nobody/Anonymous (nobody) Date: 20050922 13:06 Message: Logged In: NO Hello. Installed Maxima 5.9.1 today and the first time I tried it, it crashed my xserver.

I didn't realize that marking it "pending" would cause it to be closed in 14 days automatically. Oh well.  Comment By: SourceForge Robot (sfrobot) Date: 20050914 20:20 Message: Logged In: YES user_id=1312539 This Tracker item was closed automatically by the system. It was previously set to a Pending status, and the original submitter did not respond within 14 days (the time period specified by the administrator of this Tracker).  Comment By: Nobody/Anonymous (nobody) Date: 20050831 14:58 Message: Logged In: NO No, I'm afraid my version of xmaxima is uptodate, I installed from maxima5.9.1, and have never installed any version previously. I'm still getting "kill TERM 1". My RunMaxima.tcl file is version 1.18, and the version string embedded in the concatenated xmaxima file in my path matches that value. If you see the loop at line 295, it will only continue to the "xmaxima is running" state when pid becomes something other than "none". Apparently, it's coming back set to 1.  Comment By: Robert Dodier (robert_dodier) Date: 20050831 08:37 Message: Logged In: YES user_id=501686 It would appear that you're running an old version of xmaxima; at present the default value for pid is "none". The "kill 1" bug appears to have been fixed in r1.15 interfaces/xmaxima/Tkmaxima/RunMaxima.tcl (see http://cvs.sf.net/viewcvs.py/maxima/maxima/ and drill down from there). If your xmaxima says ``set pid 1'' instead of ``set pid "none"'' then your version is out of date. Is there more than one xmaxima on your system?
