problem building pike7.6 on alpha
by Henrik Andreasson 09 May '08

09 May '08

Anybody with a Alpha around to test this? http://buildd.debian.org/fetch.cgi?&pkg=pike7.6&ver=7.6.112-1&arch=alpha&st… I saw a discusion about this maybe being libjpeg's fault, if it's so can we workaround it or help fix libjpeg. This stops pike76 from entering testing, thus being a part of lenny. //Henrik Andreasson

MySQL Stored procedures, empty resultset problem
by cschalkwijk 09 May '08

09 May '08

On calling a stored procedure which has (results in) an empty resultset, I get the following error message: PROCEDURE {SPROC_NAME} can't return a result set in the given context When looking up the error message on the MySQL website, the explanation does not seem to match the problem, because when there is a result (one or more) in the resultset, the problem does not occur. What am I doing wrong? (using the connect_option 0x20000 does not make a difference) Greetings Coen __________________________________________________________ Deze e-mail en de inhoud is vertrouwelijk en uitsluitend bestemd voor de geadresseerde(n).

Very strange string literal problems
by cschalkwijk 06 May '08

06 May '08

(["connect_options":2]) When I tried adding the above mapping to my code. Roxen started, but remains unreachable via a webbrowser. But, and this is the strange part, when I change the string literal from "connect_options" to for example "variable", Roxen starts and is available. Isn't this strange?! I know this is the exact cause for the change to occur, since it is truly the only thing that was changes. Oh, I forgot to mention that I'm NOT EVEN USING the mapping :) . The error/strange behaviour purely results from creating the mapping: catch { mapping(string:int) tst_opt = (["connect_options":2]); dbconn = Sql.Sql( QUERY(db_string)); }; I didn't get to the part of actually using the mapping yet. __________________________________________________________ Deze e-mail en de inhoud is vertrouwelijk en uitsluitend bestemd voor de geadresseerde(n).

Spear !
by PeterPan 06 May '08

06 May '08

Hi! Pike team. I hooked Pike's compile_string() and compile_file(), and got a "new" language. I named it "Spear". In Spear, you can embed C code in Pike, and reference the variables each other. see the example: $ cat hello.spear #! /usr/bin/env spear void main() { C.INCLUDE("#include <stdio.h>"); C.CC("gcc -shared -fPIC"); string s="pike"; int n=2008; float pi=3.1415926535; C{ char* str="c string"; int m=514; double e=1.41421; printf("hello world!\n"); printf("printf %s string\n",STRING{s}); printf("printf pike int: %d\n",INT{n}); printf("printf pike float: %f\n",FLOAT{pi}); P{s="modify";} printf("%s pike var\n",STRING{s}); P{write("write %s\n",STRING{str});} P{write("write c int: %d\n",INT{m});} P{write("write c float: %f\n",FLOAT{e});} } } $ pike -x spear hello.spear hello world! printf pike string printf pike int: 2008 printf pike float: 3.141593 modify pike var write c string write c int: 514 write c float: 1.414 How to install: Extract the attachment in Pike-v7.7-snapshot and make. Please see the README-spear: $ cat README-spear Install: tar xzvf snapshot.tar.gz cd Pike-v7.7-snapshot tar xzvf ../Pike-Spear-vN.N.NNNNNNNNN.tar.gz Note: * src/Makefile.in is base on Pike-v7.7.44-20080421, do a vimdiff before use with a diffrent version of Pike.

...hm, I thought I had a newer Pike. Doesn't trigger with 7.7.39, is it fixed?

inherit resolving problem
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 03 May '08

03 May '08

If I create a module X.pmod with the contents class Y { class X { } } and then tries to run the following program class Z { inherit X.Y; } void main() { } I will get the error that 'Index Y not present in module "X".' Doing other things with X.Y is however possible, like declaring a variable "X.Y foo;" in the Z class or making the statement werror("%O\n", indices(X.Y)); in main().
