make depend (7.5 cvs)
by David Hedbor ＠ Pike developers forum 20 Feb '03

20 Feb '03

Ok, so I ran into a problem because rusage.h has been renamed pike_rusage.h due to old dependencies. Thus I run "make depend". However this fails as well, because make depend compiles Pike. This is no good - make depend should make dependencies! I have to manually edit the 'dependencies' files. How about using the method used by PExts instead - the configure process creates the dependencies. Works really well I think (does of course make configuration slower).

Mysql
by Marcus Agehall (Tr�dl�s) ＠ Pike (-) developers forum 19 Feb '03

19 Feb '03

I just found a bug in Pike under Solaris. I changed the layout of my mysql installation a bit and therefor I had to put some new options in my /etc/my.cnf. Since I want my pike-applications to use that file for the defaults, I tried object o = Sql.sql("mysql://localhost/db", ([ "mysql_config_file":"/etc/my.cnf" ])); which should give me access to the database. Instead I get a backtrace. After some investigation, I've found the following in modules/Mysql/mysql.c: static void pike_mysql_set_options(struct mapping *options) { struct svalue *val; #ifdef HAVE_MYSQL_OPTIONS #ifdef MYSQL_READ_DEFAULT_FILE if ((val = simple_mapping_string_lookup(options, "mysql_config_file")) && (val->type == T_STRING) && (!val->u.string->size_shift)) { printf("READING MYSQL-DEFAULTS..."); mysql_options(PIKE_MYSQL->mysql, MYSQL_READ_DEFAULT_FILE, val->u.string->str); } #endif ... #endif The code above is where Pike indeed does load the my.cnf file. After inserting a few printfs I concluded that the second ifdef statement is false and thus the code within the inner ifdefs doesn't execute. MYSQL_READ_DEFAULT_FILE & Co are defined within mysql.h from the MySQL source within an enum construction. If I try to print the value of it using a printf, it shows that MYSQL_READ_DEFAULT_FILE==4. So, what causes all the inner ifdefs in pike_mysql_set_options() to fail? Right now I'm using one of the latest Pike 7.3 from CVS and a mysql 4.0.10-gamma server.

cmod
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 19 Feb '03

How do I make a PIKEVAR in a .cmod static? The following PIKEVAR string digits flags ID_STATIC; (derived from how you make PIKEFUNs statuc) does not work at all. Neither do the more intuitive attempts PIKEVAR static string digits; or static PIKEVAR string digits; So what is the correct incantation?

Overlapping ranges
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 18 Feb '03

Pike v7.5 release 3 running Hilfe v3.5 (Incremental Pike Frontend) > array_sscanf("hej", "%[\x6dd\x70f\x780]"); Overlapping ranges in sscanf not supported. HilfeInput:1: HilfeInput()->___HilfeWrapper() > Sorry? Where is the range, and what is it overlapping with? If I remove either of the three characters from the set, the code works...

String.Bootstring

What is a Bootstring? Both the testsuite and the documentation appears to be somewhat lacking in describing this class.

Sql.[Ss]ql
by rjb ＠ Pike developers forum 18 Feb '03

18 Feb '03

OK, I know that by current conventions, the class's name should be Sql.Sql. Still, Sql.sql used to resolve to the same program in 7.2, and probably -- up to some point -- in 7.3... but no more. That is, Sql.sql returns zero.

Extending autodocs (2nd try)
by Xavier Beaudouin 18 Feb '03

18 Feb '03

Hello, As maintainer of Caudium, I'd like to use pike autodocs for : - caudium modules - tags - containers - entities I'd like to know if current pike autodocs can be extended to handle such extensions, if yes is there any examples / plugins or some docs (except as usual "use the source luke") to handle that. Note this part is really a *wanted* feature for others projects like sTeam, and maybe this should be "a plus" for Roxen as well. Sincerly, /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader. Please visit http://caudium.net/, home of Caudium & Camas projects O ascii ribbon campaign against html email |\ and Microsoft attachments

unnecessary tpike
by David Hedbor ＠ Pike developers forum 18 Feb '03

18 Feb '03

So, I'm compiling with icc. Problem is that with icc, linking is slow when you have IPO enabled since it performs multi-file optimizations. Pike will ALWAYS create a tpike binary even though there is a working Pike installed (so that step is unnecessary). It adds a significant time to the compilation (several minutes I'd guess). How about, if possible, use the system-installed Pike to run the generation of peep.c etc, skipping the redundant 'tpike' step. I can understand why there's been no optimizations done here since in general it doesn't take a whole lot of time.

setsid
by Peter Bortas ＠ Pike developers forum 16 Feb '03

16 Feb '03

I have a sudden urge to remove the only expect script on my systems. To do that I have to be able to set passwords with Solaris passwd. I've tried this once before, and failed. Short version of the expect script: ----8<------------------------------------- spawn /usr/bin/passwd -r nis $uname expect { -re assword: { send "$password\n" } } expect { -re assword: { send "$password\n" } } expect { eof { wait } } ----8<------------------------------------- In pike that should be something like this: ----8<------------------------------------- #!/usr/bin/env pike array(Stdio.File) make_ptypair() { Stdio.File pf = Stdio.File(), tf = Stdio.File(); foreach(get_dir("/dev/"), string pty_name) if(pty_name[..2]=="pty" && pf->open("/dev/"+pty_name, "rw")) { if(tf->open("/dev/t"+pty_name[1..], "rw")) return ({ pf, tf }); pf->close(); } return 0; } int main() { string luser = "victim"; array(Stdio.File) f = make_ptypair(); if(!f) { werror("No PTYs available.\n"); return 1; } object p = Process.create_process( ({ "/usr/bin/passwd", luser }), ([ "setsid":f[1] ]) ); f[1]->close(); f[0]->write("bogus\n"); f[0]->write("bogus\n"); return p->wait(); } ----8<------------------------------------- But no, that still gives the password question on the command line: [root] ./setsid.pike New password: Any ideas?

pike poster design?
by Martin Baehr 16 Feb '03

16 Feb '03

hi, sTeam will be present at the CeBit in germany next month. since it is a pike application i would like to use the opportunity and also advertize pike itself. unfortunately i don't have any design skills. is there any one among this group who might help us out with designing a poster that can be used at various events, such as the CeBit, linux expos/conferences, the pike conference or others? (only a digital rendition would be needed, as we have printing facilities at the university) having such a poster would help the pike project a great deal greetings, martin.
