completing the reference
by Martin Bähr 16 Dec '03

16 Dec '03

hi, again and again i find it hard to locate certain pieces of documentation. problems as far as i can see them are: the chapterized reference manual contains a lot of stuff also found in the tree reference. (the module stuff (chapters 9-17)) the tutorial contains stuff that is not in the manual. (notably the definition of static) some things from the tutorial better fit into the reference: Terminology / Glossary Expressions (a tutorial should only explain things needed at that point) any objections to me trying to move things around and mess them up? :-) greetings, martin.

I think we have an interesting resolver problem: | Pike v7.5 release 15 running Hilfe v3.5 (Incremental Pike Frontend) | > Protocols.Bittorrent.Port; | ...Torrent.pike:377:Too many arguments to clone call. | ...Torrent.pike:377:Expected: function( : object(is 65691)) | ...Torrent.pike:377:Got : function(object(implements 65692) : void | mixed) | ...Torrent.pike:517:Must return a value for a non-void function. | ...Torrent.pike:654:Must return a value for a non-void function. | ...Torrent.pike:868:Must return a value for a non-void function. | ...Torrent.pike:906:Must return a value for a non-void function. | ...Torrent.pike:914:Must return a value for a non-void function. | ...Torrent.pike:917:Must return a value for a non-void function. | ...Torrent.pike:985:Must return a value for a non-void function. | ...Torrent.pike:1060:Class definition failed. | ...Torrent.pike:1070:Must return a value for a non-void function. | ...Torrent.pike:1123:Must return a value for a non-void function. | ...Port.pike:6:Error looking up 'Torrent' in module '.'. | ...Port.pike:27:Must return a value for a non-void function. | Compiler Error: 1:Error looking up 'Port' in module 'Bittorrent'. | Pike v7.5 release 15 running Hilfe v3.5 (Incremental Pike Frontend) | > Protocols.Bittorrent.Torrent; | (1) Result: Protocols.Bittorrent.Torrent | > Protocols.Bittorrent.Port; | (2) Result: Protocols.Bittorrent.Port Any clues how to fix that?

Freetype2
by Peter Bortas ＠ Pike developers forum 14 Dec '03

14 Dec '03

The Freetype people seems to have invented a new way of handling their headers. Is this solved in any of the trees? From the package available in latest Debian testing combined with 7.4-HEAD: conftest -g -mcpu=i686 -I/usr/include/freetype2 conftest.c -lfreetype -lz -ldl -lrt -lnsl -lm -lpthread -lcrypt 1>&5 In file included from configure:1104: /usr/include/freetype2/freetype/freetype.h:20:2: #error "`ft2build.h' hasn't been included yet!" /usr/include/freetype2/freetype/freetype.h:21:2: #error "Please always use macros to include FreeType header files." /usr/include/freetype2/freetype/freetype.h:22:2: #error "Example:" /usr/include/freetype2/freetype/freetype.h:23:2: #error " #include <ft2build.h>" /usr/include/freetype2/freetype/freetype.h:24:2: #error " #include FT_FREETYPE_H"

convenience function
by Mirar ＠ Pike developers forum 14 Dec '03

14 Dec '03

Any good place to put this convenience function? I seem to use it a lot, so I thought I should just add it to the tree. function(int,int:void) progress_bar(string name,int steps) { int inited=0; int lastpos=0; return lambda(int n,int m) { if (!inited) write(name+"["+"."*steps+"]\r"+name+"["),inited=1; int pos=(steps*n)/m; if (pos!=lastpos) { write("#"*(pos-lastpos)); lastpos=pos; } if (n==m) write("\n"); }; } It will output a progress bar, like my progress: [##########_ ] and end it with \n when it's full.

bittorrent
by Mirar ＠ Pike developers forum 14 Dec '03

14 Dec '03

I have added Bittorrent capabilities to Pike, under Protocols.Bittorrent. There is also an example of a tiny agent (what's it called - it's not really a client). Enjoy. :) I have a more elaborate downloader then the example in http://www.mirar.org/btdownload.pike.txt mostly containing of prettyprinting to a vt100(xterm)-like terminal of the current status (*lots* of flashing stuff).

Java failure
by Jonas Walld�n ＠ Pike developers forum 12 Dec '03

12 Dec '03

Does someone (i.e. Marcus :-) have the source to conftest.class which is used by the Java testsuite? I'm seeing an error on OS X (both JDK 1.3.1 and 1.4.1) where double values are sent as either 0.0 or Inf so I'd be interested in adding debug code to the Java side. Could this be as simple as a struct padding or data alignment error? None of the other data types in that test fail, only double values.

How to dump pike modules in a fakeroot/sandbox environment?
by Rainer Groesslinger 11 Dec '03

11 Dec '03

Hi, I am having a problem building pike in a fakeroot/sandbox'ed environment and *additionally* dump the pike modules. (to avoid those problems you surely have heard about hundred times when building in a fakeroot and then try to run a pike application using a module: /usr/lib/pike/.../.../whatever.pmod.o:-: Warning: Decode failed: Failed to decode program) The problem I am having is, pike seems to be able to dump the modules when installing in a fakeroot environment from what I can read in the install scripts but it cannot do it without violating the sandbox (e.g. writing outside the fakeroot). In short, I do the following (after pike was built using make CONFIGUREARGS="..." etc.): sed -i s/rm$mod\+\"\.o\"$\;/\{\}/ for install.pike, which results in the following: --- install.pike.orig +++ install.pike @@ -1096,7 +1096,7 @@ rm("dumpmodule.log"); foreach(to_dump, string mod) - rm(mod+".o"); + {} // Dump 25 modules at a time I need to do this, because otherwise the sandbox is violated since pike directly wants to do some action in /usr/lib/... Then I use the following command to install pike: make INSTALLARGS="--traditional" buildroot="${D}" install ("${D}" being the virtual "/") Because of the change to install.pike, the modules aren't dumped automagically, and to be honest, I feel a bit lost now how I can dump the modules to avoid those fakeroot/decode problems with the modules, but without violating the sandbox. Thanks in advance for your answers, -- Rainer Groesslinger <rainer.groesslinger(a)gmx.net>

client-server/agent testsuite
by Mirar ＠ Pike developers forum 10 Dec '03

10 Dec '03

Is there any smooth way to test the Pike Protocols, for instance for client/server applications where you need to be asynchronous or to spawn off subprocesses? Is it possibly to design such a setup?

is there a fully supported win32 build available ?
by Jed Adams 09 Dec '03

09 Dec '03

according to the latest release 7.4.31 DVB................. no (dependencies failed) FFmpeg.............. no (dependencies failed) GTK.GlArea.......... no (dependencies failed) GTK.GladeXML........ no (dependencies failed) Gdbm................ no (dependencies failed) Gnome............... no (dependencies failed) Image.SVG........... no (dependencies failed) Image.TIFF.......... no (tifflib version 42) Mird................ no (no system libmird, can not use included) Oracle.............. no (dependencies failed) PDF.PDFlib.......... no (dependencies failed) PDF.Panda........... no (dependencies failed) Perl................ no (forced without) Postgres............ no (dependencies failed) SDL_mixer........... no (dependencies failed) Ssleay.............. no (forced without) now out of all of these i'm really interested in GTK.GlArea and also the build i have doesn't have GLUT support either i've looked at most of the samples and the few i can find for GL use either of these so my question is , is anyone working on either of these ? or is there a nice tutorial on building the whole shebang on windoze ? thamks for your time Jed

"thread_create"
by Jaroslaw Sitek 08 Dec '03

08 Dec '03

Hello I would like to ask if there were any changes in implementing threads between version 7.2 and 7.4 (stable) or rather what exactly has changed? The code of my function (implemented in master): object _load_thread(string path, mixed ... args) { program prg = _compile(path); string objid; object obj; array(string|int) err; if (objs[path]) return objs[path]; if (!prg) return 0; err = catch { obj = prg(@args); thread_create(obj->run); }; if (err) { werror(err[0]); werror(describe_backtrace(err[1])); } ... works perfectly in version 7.2, it creates suitable number of threads when it is called on a given objects. But the same function called on the same objects in version 7.4 creates only one (first) thread and though the compiler doesn't return any error messages when the function is initialized, threads are not 'loaded'. To check if threads are created I simply: ps aux|grep pike There are no names of threads, just the process is visibly divided into as many threads as the number of objects called in individual call. Could anyone tell me what is the problem? My system: Linux, Debian, i686 Aron@Valhalla
