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

Pike 7.4.30
by Martin Nilsson (ja till euro, nej till cent) ＠ Pike (-) developers forum 15 Sep '03

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

(3) Result: 1 > Variable "x" is declared and accessible (1). I do something wrong? Regards, /Al

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

benchmark in xenofarm
by Mirar ＠ Pike developers forum 13 Sep '03

13 Sep '03

Hm, would it be possible to benchmark at the end of the xenofarm build? It would be interesting to be able to see performance graph versus revision (time). :) (But maybe people don't want to spend the extra cpu-minute or so?)

Pike on WinXP (native)
by Alexander Demenshin 13 Sep '03

13 Sep '03

Hi, Just tried to assemble, installed nt-tools, etc... Finally get trouble: configure: error: /bin/bash '/net/troll/E/pike-devel/7.4/src/modules/Gmp/configure' failed for Gmp Where to get GMP for win32 which will be recognized by Pike's configure? NB: If somebody curious - I just think that it might be useful if I install xenofarm client on WinXP... :) Regards, /Al

Mutex protection
by David Gourdelier 13 Sep '03

13 Sep '03

Hi again, I have another question regarding thread safe programming in Pike. If you have a global object m and that several threads can write to m->foo (where foo is a public variable of this object), then do you need to protect access to m->foo or the entire m object ? Is it the same if it is a mapping ? -- David Gourdelier

sdl
by Mirar ＠ Pike developers forum 10 Sep '03

10 Sep '03

I'm trying to get the SDL module running. At first, it didn't want to configure; when I tried to debug more specifically, it happily configured and built the SDL module, but it wont run: | > SDL; | Compiler Error: lib/modules/SDL.pmod:4:Illegal program pointer. | Compiler Error: 1:Undefined identifier "SDL". | > ___SDL; | Compiler Error: 1:Error resolving '___SDL'. | Compiler Exception: load_module("/usr/local/pike/7.5.12/lib/modules/___SDL.so") failed: /usr/local/pike/7.5.12/lib/modules/___SDL.so: undefined symbol: SDL_JoystickEventState | /usr/local/pike/7.5.12/lib/master.pike:741: | master()->low_findprog("/usr/local/pike/7.5.12/lib/modules | /___SDL",".so",Tools.Hilfe.StdinHilfe()->HilfeCompileHandl | er(),1) | /usr/local/pike/7.5.12/lib/master.pike:797: | master()->findprog("/usr/local/pike/7.5.12/lib/modules/___ | SDL","",Tools.Hilfe.StdinHilfe()->HilfeCompileHandler(),1) | /usr/local/pike/7.5.12/lib/master.pike:828: | master()->low_cast_to_program("/usr/local/pike/7.5.12/lib/ | modules/___SDL","/.",Tools.Hilfe.StdinHilfe()->HilfeCompil | eHandler(),1) | /usr/local/pike/7.5.12/lib/master.pike:1005: | master()->low_cast_to_object("/usr/local/pike/7.5.12/lib/m | odules/___SDL","/.",Tools.Hilfe.StdinHilfe()->HilfeCompile | Handler()) | /usr/local/pike/7.5.12/lib/master.pike:1471: | master()->findmodule("/usr/local/pike/7.5.12/lib/modules/_ | __SDL",Tools.Hilfe.StdinHilfe()->HilfeCompileHandler()) | /usr/local/pike/7.5.12/lib/master.pike:1726: | master()->resolv_base("___SDL","HilfeInput",Tools.Hilfe.St | dinHilfe()->HilfeCompileHandler()) | /usr/local/pike/7.5.12/lib/master.pike:1802: | master()->resolv("___SDL","HilfeInput",Tools.Hilfe.StdinHi | lfe()->HilfeCompileHandler()) Anyone who has an idea, or should I try to hunt it down? Looks like it doesn't link with libsdl to me, which seems odd... (Gentoo, libsdl-1.2.6.)

Unicode bug?
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 10 Sep '03

10 Sep '03

I noted something that looks like a bug in make_wordbits.pike in the Unicode module: At the end it adds an entry with: if( last_was ) { write( " {0x%06x-0x%06x}\n", last_was, c ); last_was=0; } I suspect it should be ',' instead of '-' between the numbers in the write() format there, or else the printed brace list ought to have another entry. Since I don't know anything at all about how this structure is used I haven't checked in a fix.
