nice-to-have-function

Image.Image->apply_matrix is not always very useful... I'm a little busy myself, otherwise I would provide a patch, my suggestion is that someone adds a function that does this to Image.Image: Image.Image convol(Image.Image i, array(array(array(array(float)))) foo) { Image.Image ret; array(array(array(array(int)))) foo1= ( array(array(array(array(int)))) ) (foo[*][*][*][*]*100000); for(int x=0;x<3;x++) { array(int) c1=({ 0,0,0 }); c1[x]=255; array(array(array(int))) foo2=foo1[*][*][x]; for(int y=0;y<3;y++) { array(array(int)) foo3=foo2[*][*][y]; int sum=`+(0, @ foo3*({})); array(int) c2=({ 0,0,0 }); c2[x]=255; Image.Image tmp; tmp=i->gray(@c1)->apply_matrix(foo3,0,0,0, sum?100000.0/sum:1.0)*c2; if(ret) ret+=tmp; else ret=tmp; } } return ret; } I've need a function like this twice now, so I think it would be useful. Also, the implementation above is grossly inefficient.. If anybody knows a faster way to do the same thing with the currently available Image operations, let me know. Possible extentions to this function: o Add the results to an image to avoid the clipping that would occur if you did the addition afterwards. o Add x-stride and y-stride to allow it to compute only every x:th and y:th pixel to allow scaling in the same step. (Is it even possible to scale an image without averaging right now?)

Since it breaks in post modules, you should already have a (broken) pike compiled. Try to run bin/pike --gdb and see if you get the error. / Martin Nilsson (DivX Networks) Previous text: >2004-08-26 09:24: >Subject: Re: There's no master to handle the error.

#pike 7.2 does something bad...

'#pike 7.2' does something bad in Pike v7.6.6. This programs dumps core: #!/usr/local/bin/pike #pike 7.2 mixed noise1, noise2; import Image; //Needed for crash, I think int main(int argc, array(string) argv) { write("Hello!\n"); noise1=Image(147,140)->copy(0,0,60, 68); write("Hello 1!\n"); noise2=noise1->scale(2.0); //->scale 2.1 works! write("Hello 1b!\n"); noise2=noise2->copy(0,0,60, 68); //This always crash write("Bye!\n"); }

Hello, We've got a specific error on OpenBSD Sparc64 when trying to compile Shuffler : Making post_modules/Shuffler /home/kiwi/src/xenoclient/pike-7.7/red-pill.oav.net/buildtmp/Pike-v7.7- snapshot/build/openbsd-3.5-sparc64/pike -DNOT_INSTALLED -DPRECOMPILED_SEARCH_MORE -m/home/kiwi/src/xenoclient/pike-7.7/red-pill.oav.net/buildtmp/Pike- v7.7-snapshot/build/openbsd-3.5-sparc64/master.pike /home/kiwi/src/xenoclient/pike-7.7/red-pill.oav.net/buildtmp/Pike-v7.7- snapshot/src/post_modules/Shuffler/make_sources.pike /home/kiwi/src/xenoclient/pike-7.7/red-pill.oav.net/buildtmp/Pike-v7.7- snapshot/src/post_modules/Shuffler sources.h sources_to_compile There's no master to handle the error.

Segfault in backend
by David Gourdelier 23 Aug '04

23 Aug '04

Hi, While trying the Shuffler module, I had the following segfault: #0 0x0809ba20 in really_free_compat_cb_box () #1 0x406887d0 in f_Shuffle_create () from /usr/local/pike/7.6.13/lib/modules/Shuffler.so #2 0x08074ee1 in low_mega_apply () #3 0x0807608e in mega_apply () #4 0x00000004 in ?? () #5 0x088c1124 in ?? () #6 0x0000000b in ?? () #7 0x00000000 in ?? () #8 0xfffce50c in ?? () #9 0xbf7ff624 in ?? () #10 0x080dfbd7 in call_pike_initializers () Previous frame inner to this frame (corrupt stack?) The really_free_compat_cb_box function is located in backend.cmod so I guess it's backend related. The problem is 100% reproductible and I can add any debug/line of code to help for fixing it. I'm using pike 7.6.13 from CVS (built the 15/08) / David

pike -t5 fails
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 23 Aug '04

23 Aug '04

I've compiled pike 7.7 from recent CVS with CONFIGARGS="--with-debug --with-rtldebug --with-dmalloc --without-copt". The resulting binary is executable and seems to work. However, when trying bin/pike -tX (X>1), the binary fails to start hilfe. Am I the only one with this problem or can someone reproduce this behaviour?

Pikefarm client problem
by Mikael Brandström 23 Aug '04

23 Aug '04

Hi, today I tried setting up the xenofarm client to compile pike on my Mac. It is running MacOS 10.3.5 (i.e. Darwin 7.5.0) and fink. Compiling Pike suceeds (I've tried it outside xenofarm), but xenofarm fails when assembling the result with the following lines from the xeonfarmclient.txt: BEGIN response_assembly PASS END cd build/xenofarm && tar cf - . > ../../xenofarm_result.tar tar: ./compilelog.txt: file changed as we read it tar: Error exit delayed from previous errors make: *** [xenofarm] Error 2 Any clues on how to fix this error? cheers, Mikael

CMOD and namespace placement
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 23 Aug '04

23 Aug '04

I want to write a module Bar that should work like a pmod-file and that should appear within the Pike namespace as Foo.Bar. What is the (best) way of doing that using CMOD?

pike 7.6 bump version ?
by Xavier Beaudouin 23 Aug '04

23 Aug '04

Hello there, Can pike 7.6 be bumped version ? Because Bill have fixed some SSL problems that can help us @Caudium Group to identifiate the good pike to run with Caudium 1.3 ? 7.6.11 is from 01/07/2004... So it can be good to have 7.6.13 from August ? Thanks, /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader.
