float type weirdness
by Alexander Demenshin 19 Sep '03

19 Sep '03

Hi, I was surprised that float type is somewhat "special", like here: float x = 0.0; // OK, I can live with the fact that I just can't assign "0" :) // However, it would be convenient to make an exception for this // special case (zero) if (!x) something(); // Will be never called, since x is _always_ true // while it is (numerically) is zero (7.4.20) Is this intentional? According to the tutorial: "When Pike encounters an if statement, it first calculates the value of the expression. Pike then checks if this value is true or false. The value zero (0) is considered to be false, and everything else is true." It is not mantioned that "zero" has to be integer zero, and everywhere else (C, Perl etc) float zero is false.

Catching segfault
by David Gourdelier 15 Sep '03

15 Sep '03

Hello list, I have a segfault with a Pike that happens rarely on a busy Camas server. To get a backtrace and fill a bug report I've tried to run it into gdb however I didn't get any segfault for now and I can't run it into gdb for a long time since it is a production server (I saw this error only one time on the development server, too few traffic). Maybe it's not even possible to have a segfault inside gdb because of a strange side effects (maybe the segfault occurs only on a fast process or something). So I'd like to know if it would be possible to catch SIGSEGV in Pike and output a backtrace so that: . You might get more bug reports. . It would be possible to track problems when it's not possible to run inside a debugger or that the error don't happen in this case. Thank you for your reply. -- David Gourdelier

Segfault with GMP (7.4.27/CVS)
by Alexander Demenshin 15 Sep '03

15 Sep '03

Hi, Got it (takes several minutes on P4-1.7G): Pike v7.4 release 27 running Hilfe v3.5 (Incremental Pike Frontend) > gauge { Gmp.fac(10000000); }; Segmentation fault Why I tried this? Just to make some load and measure memory usage :) But there is a problem anyway... Just imagine Pike script in Roxen/Caudium trying to do this... When argument is 10 times less, it is OK. Regards, /Al

How about making a new 7.4 release this week? I've already taken the time to do the most boring part; updating CHANGES.

IDA's policy on Pike contributions
by Alexander Demenshin 14 Sep '03

14 Sep '03

Hi, I am not quite sure that this list is right place to ask, but anyway... There is following policy (at http://pike.ida.liu.se/development/cvs/policies.xml): ---snip--- Pike copyrights - we consider all contributions to Pike donations and _claim copyright_ for the entire Pike repository. This also means that IDA will have full power to take _legal actions_ against anyone who would actually manage to break the license. ---snip--- If I undesrtand this right, it basically means that I can't use my code anymore as I wish (and lose my copyright), once it is officially accepted and used in Pike. With policy like this no wonder that contributions from the community are so small... Regards, /Al
