file_peek and async_connect
by Arne Goedeke ＠ Pike developers forum 30 Jul '07

30 Jul '07

I found some strange behaviour using async_connect when connecting to unbound ports on localhost. The callback is never called. Try something like this: void cb(mixed ... args) { write("cb: %O\n", args); } int main () { object o = Stdio.File(); o->async_connect("127.3.3.5", 3245, cb); return -1; } A reason I found for that (not sure if there are more issues, it fixes this problem though) is that 1) in __stdio_close_callback() read(0,1) is used to check if data can be read from the socket instead of peek(). 2) file_peek() does not check for POLLERR or POLLHUP and therefore returns true even if the socket has been closed or some error occured using peek() instead of read(0,1) in __stdio_close_callback() and adding }else if (fds.revents & (POLLERR | POLLHUP)){ ret=0; to file_peek() fixed this issue for me. The same problem may occur when using select() in file_peek(), I did not test that though. arne

SDL/GL(UE) on Darwin
by Johan Sundstr�m (Achtung Liebe!) ＠ Pike (-) developers forum 29 Jul '07

29 Jul '07

I've been looking into running a GLUE application under OS X, and hit the error described on http://www.ogre3d.org/wiki/index.php/MacLibrary (a slew of NSAutreleasepool warnings followed by a "*** Uncaught exception: <NSInternalInconsistencyException> Error (1002) creating CGSWindow") and a crash in SDL.set_video_mode on its first glGet call. This (completely naïve) approach based on the suggestions offered did not seem to do much good: Index: src/post_modules/SDL/SDL.cmod =================================================================== RCS file: /pike/data/cvsroot/Pike/7.7/src/post_modules/SDL/SDL.cmod,v retrieving revision 1.29 diff -u -r1.29 SDL.cmod --- src/post_modules/SDL/SDL.cmod 12 Nov 2005 20:37:07 -0000 1.29 +++ src/post_modules/SDL/SDL.cmod 29 Jul 2007 21:07:04 -0000 @@ -151,6 +151,13 @@ *! */ PIKEFUN void init(int flags) { + /* init needed on XDarwin: http://www.ogre3d.org/wiki/index.php/MacLibrary */ + void* cocoa_lib; + cocoa_lib = dlopen( "/System/Library/Frameworks/Cocoa.framework/Cocoa", RTLD_LAZY ); + void (*nsappload)(void); + nsappload = (void(*)()) dlsym( cocoa_lib, "NSApplicationLoad"); + nsappload(); + if( SDL_Init(flags) == -1) { Pike_error("SDL Initialization failed: %s\n", SDL_GetError()); }

Monger
by Peter Bortas ＠ Pike developers forum 28 Jul '07

28 Jul '07

Monger still gives a backtrace if you try to query a nonexistent module. Would be nice to have fixed before the next stable and should be easy to fix for anyone that has 10min free. Example: % pike -x monger --query gazonk No such module gazonk. /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:428: Tools.Monger.MongerUser()->xmlrpc_handler()->_caller()->`()("gazonk") /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:196: Tools.Standalone.monger()->get_module_action_data("gazonk",0) /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:165: Tools.Standalone.monger()->do_query("gazonk",0) /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:123: Tools.Standalone.monger()->main(3,({"/usr/local/pike/7.6.117/lib/modules/T ools.pmod/Standalone.pmod/monger.pike","gazonk"}))

Re: [Announce] Pike: an Introduction now available
by Jonas Walld�n ＠ Pike developers forum 25 Jul '07

25 Jul '07

Speaking of that, one not-so-minor cosmetic detail that I'd like to see changed in the book is the page header font size. Right now it is very big which causes the headers to look like section titles in the main flow of the text. This has confused me more than once when browsing Grubba's copy. For an example, look at http://www.lulu.com/browse/preview.php?fCID=78730 and navigate to, say, page 2. (FYI, while looking at the web preview I noticed a typo on page iv: "Institionen" -> "Institutionen".)

[Announce] Pike: an Introduction now available
by H.William Welliver III 25 Jul '07

25 Jul '07

[My apologies for the double posting. I was apparently too excited to include a subject in my previous post. ] Good evening Pike fans, We're pleased to announce the immediate availability of Pike: An Introduction. Three years in the making, Pike: An Introduction is the definitive introduction to the Pike programming language. Weighing in at almost 300 pages, the book contains numerous examples which coincide with topics of discussion, as well as a chapter on the basics of several popular modules. Proceeds from sales of Pike: An Introduction will be used to help fund Pike development and marketing. That means that, in addition to getting up to speed on your favorite programming language, you'll also be helping to advance and promote Pike. We expect the book to be available at online outlets such as Amazon or Barnes and Noble in about a month. Until then, you can get your copy from Lulu, our printing vendor for USD 29.95. In addition to getting your book sooner, Lulu's commissions are lower, meaning that a larger percentage of your purchase price will be made available for supporting the Pike community. Learn more about the book, and purchase your copy today by visiting: http://book.gotpike.org/ As always, your comments and suggestions are welcome! Best, Bill Welliver and Martin Bähr, editors !DSPAM:469c3c07195971412658825!

Ubuntu
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 24 Jul '07

24 Jul '07

I just reinstalled Ubuntu and it looks like I'm having some problems with some of the modules in 7.6. To get GTK to configure I added my own GTK_CONFIG=/usr/bin/gtk-config after the detection. To get freetype to compile I added my own FT_CONFIG="/usr/bin/freetype-config". How should this really be solved?

thread_create() doc
by Hedda (www.linkmeet.com/_SOF2007Cortege) ＠ Pike (-) developers forum 18 Jul '07

Shouldn't thread_create() be listed on namespace predef on http://pike.ida.liu.se/generated/manual/modref/ ? Or is it somehow hated because Thread.Thread()->create() exists?

Protocols.DNS.gethostbyname()
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 17 Jul '07

17 Jul '07

I came across a problem in Protocols.HTTP.Session last week. It seems the Session module uses gethostbyname() to perform DNS lookups and then randomly selects one of the returned IP addresses. This can cause problems under 7.7 if the selected IP is an IPv6 address and the host doesn't have IPv6 connectivity. Rather than rewriting the Session module DNS lookup, I would like to add an optional argument to the gethostbyname() method to allow selection of the types to be returned. Any thoughts?
