Process.run
by Peter Bortas (nu med mindre Opera) ＠ Pike (-) developers forum 14 Jul '08

14 Jul '08

I just checked in a Process.run() in 7.7: http://pike.ida.liu.se/development/cvs/diff.xml?module=Pike&file=7.7/lib/mo… The rational for that is that I was once again reminded by a user this week that getting Process.create_process() or Process.Process right without some corner case blocking is hard. It's not obvious that if you bind pipes to booth stderr and stdout you have to take in to account that OS buffers are not limetless. Process.run() is a thin wrapper around Process.Process that collects stdout, stderr and exitcode and return them in a mapping. This could potentially result in huge strings, but will do what most users want and even already do when they call create_process() with both pipes bound. Something like this should be in 7.8, but I'm open to suggestions for other things that might be usefull to return in the mapping or for changing member names.

pre 7.2 lib/modules/SSL.pmod ,v files
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 03 Nov '06

In trying to convert the Pike CVS repositories to Subversion, I've come across something really odd. Looking at the ,v files in /pike/data/cvsroot/Pike/7.2/lib/modules/SSL.pmod, it seems that this module was created on 1997-03-13, and included in such tags as "pike_v0_5_release_47". Yet, there is no trace of this module under /pike/data/cvsroot/Pike/0.5 (or 0.6, or 7.0), under this name or any other as far as I can tell. Where are the missing ,v files? Did somebody miss some CVSROOT/modules magic when copying the repositories from RIS?

It is time for a new release of Pike 7.6. Is there anyone who can do the release notes? If not, we'll just wait a bit longer...

I also refined the approach by removing the separate dir as soon as it is added to 0.6 (i.e. it is actually _renamed_ to Pike/0.6/lib/modules/Remote.pmod as soon as there is a Pike/0.6/lib/modules to put it in).

configure.in $Id$

Is it possible to use the value from AC_REVISION in the section that generates posix_to_native.sh in configure.in, to keep the diff noise down?

bug report: casting to array mistake of multiset
by 郭雪松 23 Jul '06

23 Jul '06

You ignore my bug report for a long time. A item lost when casting a multiset to array!!!! mapping special_attrs=([]); void main() { multiset from=(<>); array _to=({(<"Stone","1","%70">),(<"Stone","2","%70">)}); multiset to; array rate=({}); int sum; foreach(_to,multiset m){ int found; foreach(m;string k;int one){ if(k[0]=='%'){ int n; sscanf(k,"%%%d",n); rate+=({n}); sum+=n; m[k]=0; found=1; break; } } if(!found){ rate+=({1}); sum+=1; } } //int r=random(sum); int r=80; for(int i=0;i<sizeof(rate);i++){ if(r<rate[i]){ to=_to[i]; break; }else{ r-=rate[i]; } } multiset unchanged=from&to; multiset special_add=(to-unchanged)&(multiset)(indices(special_attrs)); multiset special_del=(from-unchanged)&(multiset)(indices(special_attrs)); multiset direct_del=filter(from-unchanged,lambda(string x){if(x[0]!='!') return 1;else return 0;}); multiset direct_add=to-unchanged-special_add; werror("direct_add=%O\n",(direct_add)); werror("BUT (array)direct_add=%O\n",(array)(direct_add)); } Output: direct_add=(< /* 1 element */ "Stone", "2" >) BUT (array)direct_add=({ /* 1 element */ "2" })

Re: new ground with windows
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 23 Jul '06

You have to use -MD, both for pike.exe and all modules, when you use dlls. That's the only way to make them share the same CRT instance, which is vital for memory management to work. I suggest you try with --enable-dll (assuming a recent 7.7) which fixes that and other things. Note that I'm still not finished with the dll stuff. Notably I have a lot of uncommitted changes to make the installer work. Haven't done much about it lately since I'm on vacation and mostly off-net (will still be for another week).

new ground with windows
by H. William Welliver III 23 Jul '06

23 Jul '06

Ok, I've managed to compile one of my C modules on windows (the XML2 parser glue), but I'm running into problems with dynamic module loading in pike. The libxml2 module uses some functions like modf and log10. Because libxml2 is being compiled as a library, the c library doesn't appear to be linked. Similarly, when I make the module, these symbols (and the snprintf pointer in the following error message) don't seem to be getting linked in. Thus, when I try to load the compiled module into Pike, I end up with undefined symbols. The question is, how do I work around it? I can get the regular functions like log10 and fmod to be linked into Pike by creating dummy functions that use them, but then that will only work with my copy of pike and not anyone elses. Similarly, I'm not sure what to do with the __imp records. Is dlopen not aware of how to resolve these? Any thoughts and suggestions would be greatly appreciated!

-mcpu

I get `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead. for every file comiled in MinGW. Is there anything someone more configure proficient can do to reduce the spam?

/usr/local/include
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 23 Jul '06

While trying to compile Pike under MinGW I've encountered the problem that include files in /usr/local/include isn't found. First place of error is in the Gmp module. configure:1574: checking for gmp.h configure:1584: gcc -E conftest.c >/dev/null 2>conftest.out configure:1580:17: gmp.h: No such file or directory configure: failed program was: #line 1579 "configure" #include "confdefs.h" #include <gmp.h> If I manually add -I/usr/local/include it works, but what is the correct, general solution?
