configure
by Martin Nilsson (har bott i google) ＠ Pike (-) developers forum 28 Mar '03

28 Mar '03

configure.in in _math says AC_CHECK_HEADERS(ieeefp.h fp_class.h floatingpoint.h) and later does #ifdef HAVE_FP_CLASS_H #include <fpclass.h> #endif in the test for HAVE_WORKING_FPSETMASK. HAVE_FP_CLASS_H is not used at all in math.c. There is at least one thing wrong here, right?

%-8F

Is it a conscious choice that %F doesn't honor the minus flag? | > sscanf("\0\0\0\0\x29\xf0\x3c\x41","%8F",x),x; | Result: 0.000000 | > sscanf("\0\0\0\0\x29\xf0\x3c\x41","%-8F",x),x; | Result: 0.000000 | > sscanf(reverse("\0\0\0\0\x29\xf0\x3c\x41"),"%8F",x),x; | Result: 1896489.000000 | > sprintf("%8F",1896489.0); | Result: "A<ð)\0\0\0\0" | > sprintf("%-8F",1896489.0); | Result: "A<ð)\0\0\0\0" It makes it a bit unnecessary difficult to read binary floats produced by Intel machines.

SDL-fel
by Peter Bortas ＠ Pike developers forum 24 Mar '03

24 Mar '03

The problem with the SDL module is that the configure test doesn't find _main. I don't know why yet, but I have removed the kludge. configure:1069: checking for SDL - version >= 1.2.0 configure:1190: /mnt/aphraelraid/home/peter/hack/Pike/7.4/build/windows_xp-5.1.2600-x86/smartlink rntcl -o conftest -I/usr/local/include -I/usr/X11R6/include -R/usr/local/lib -L/usr/local/lib -R/usr/X11R6/lib -L/usr/X11R6/lib conftest.c -lshell32 -lkernel32 -lws2_32 -ladvapi32 -lm -lsdl 1>&5 LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main conftest.exe : fatal error LNK1120: 1 unresolved externals CL returned error code 2.

for-loop optimization
by Marcus Agehall (Tr�dl�s) ＠ Pike (-) developers forum 21 Mar '03

21 Mar '03

I just wrote a for-loop like this: string foo="gazonk"; for(int i=0;i<sizeof(foo);i++) { ... do stuff ... if (sometimes) foo = foo[1..]; ... do stuff ... } The problem I discoverd was that when the length of foo is changed, the loop still tries to loop over the original length of foo. The problem dissappeard when I replace sizeof(foo) with a variable and update it when changing the length of foo. Is this the correct behaviour or is the optimizer doing more than it should here?

reasons why pike is better than python?
by Martin Baehr 21 Mar '03

21 Mar '03

hi, someone posted this url: http://trific.ath.cx/resources/python/optimization/ in roxenchat with the comment that pike should have similar comments to help people optimize their code. to me this page much more reads like a list of reasons not to use pike. could someone please assert that pike doesn't have issues like these? of course some optimization suggestions pointing out what things are in fact slow would be nice too. greetings, martin.

Pike 7.4.18?
by Martin Nilsson (har bott i google) ＠ Pike (-) developers forum 20 Mar '03

20 Mar '03

It has been time for a new Pike 7.4 release for some time. How about setting sunday as a goal for source release and binaries after that as they become ready? I've made a quick summary of the changes from 7.4.10 up to 2003-03-18 21:25:45. The changes with quotations are raw CVS messages that are a bit lacking in information. Those of you responsible for them (mostly grubba I think) please make a sentence or two describing the actual bug fixed. Also, please add descriptions of changes made after 2003-03-18 21:25:45.
