Re: Status of RSS support

The API in XML.Tree is completely different. That's why I haven't converted Web.RDF already.

Status of RSS support
by Bill Welliver 26 Feb '05

26 Feb '05

I've been fiddling with Web.RSS in Pike 7.6, and I'm wondering what people are using it for. From what I can tell, it's RSS 1.0 only, and I've not been able to get it to successfully parse any of the RSS 1.0 files I've fed it. I'm not sure if I'm doing anything wrong or not. Anyone out there have any first hand knowledge of using it? On a side note, I wrote an RSS 2.0 parser; it's not complete yet, but I've had good luck with it so far. I'd be happy to pass it around if anyone's interested in helping out with it. Bill

PPC machine code vs gcc 4.0
by Jonas Walld�n ＠ Pike developers forum 25 Feb '05

25 Feb '05

I just tried compiling Pike 7.4 using gcc 4.0 (prerelease) on OS X and got an error about the CALL_MACHINE_CODE asm macro in src/code/ppc32.h clobbering r31 (which I guess is the purpose of that code). Any hints on how to get the compiler to accept it?

question about lock file or the "return -1"
by 雷炯 24 Feb '05

24 Feb '05

I wrote code : ====================================== int main() { Stdio.File f=Stdio.File("lockfile","cr"); object l=f->lock(); write("I lock the file"); sleep(8); return -1; } ======================================= I run this program in two processes,one after anthoer, the second process would write "I lock the file" after 8 secconds the first process start to run. But if i wrote ======================================= int main() { Stdio.File f=Stdio.File("lockfile","cr"); object l=f->lock(); write("I lock the file"); return -1; } ======================================= and run in two processes, one after anthoer, the second process would write "I lock the file" immediately after it started. I want to know why this happens, and why "return -1" is not work in this situation. I always think if I write "return -1" in the main(), the process will not quit and the file lock in the process will not destroy

GTK2
by Sebastian Kaminski 21 Feb '05

21 Feb '05

Hi, I'd like to use GTK+-2.x with Pike, but besides GTK2 not working with Pike there are some design flaws in the current implementation (as long as I read the source the right way). It seems that you can only use 1.2 or 2.x because there's only one GTK module. This is no problem within one program, but you have to decide when compiling Pike. In GTK 1.2 there are some identifiers that are missing in GTK 2.x and in the 2.x tree there are more widgets than in 1.2 so if a user would use Pike programs using 1.2 and 2.x he/she would need two different builds of Pike. There should be a clean distinction between GTK implementations, that's why I would suggest having an own module for GTK2. Any comments or aspects I may have overlooked? I already started implementing GTK2 as it's own module and got to the point where I can show a window with a label in it. I just wanted to ask if this makes sense or if anyone has already done this before I get to the real work. - Sebastian

pike on sparc
by Marc Dirix 20 Feb '05

20 Feb '05

Hi, On my sparc-linux it seems pike segfaults. According to gdb the location of the problem is interpreted.c In the function: eval_instruction_low. Exact location is line 1317 in the file. Seems the if-routine generates the segfault.

HTML/HTTP/XML/XHTML encoding/decoding
by Johan Sch�n (Opera, Firefruit) ＠ Pike (-) developers forum 18 Feb '05

18 Feb '05

I've been annoyed at the divergent and fragmented implementations of html_encode_string, http_decode_string, etc. in Pike for quite some time. This is what it looks like today, afaik: encode: decode: --------------------------------------------------- html | _Roxen.html_encode_string Protocols.HTTP.unentity (partial) http | Protocols.HTTP.http_encode_string _Roxen.http_decode_string xml | - - Where should we put these methods instead? Standards.{HTTP,HTML,XML}? Somewhere else?

HTML/HTTP/XML/XHTML encoding/decoding
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 17 Feb '05

17 Feb '05

Change that to Roxen.http_encode_url in the yet unreleased 4.1. The one in 4.0 doesn't handle eight bit chars correctly. (Hmm, wonder why I haven't backported it..)
