Floating point (conversion) bug (affected: v7.4 & v7.5; may be Hilfe only)
by Alexander Demenshin 26 Feb '03

26 Feb '03

Hi there, Just playing around: Pike v7.5 release 3 running Hilfe v3.5 (Incremental Pike Frontend) > (float)"0.1e99"; Segmentation fault Same for 7.4 (CVS versions two days old). And another one: Pike v7.5 release 3 running Hilfe v3.5 (Incremental Pike Frontend) > float x; > x = 1e99; Segmentation fault Seems that the problem is related to Hilfe - from file it prints value as expected, no segfaults. Regards, /Al

Optimizer problem?
by Alexander Demenshin 26 Feb '03

26 Feb '03

Hi again, So one more problem: int main(int argc, array(string) argv) { int count = 0; int ts = 0; ts = time() + 1; while (time() <= ts) /* count++ */; write("%u %u\n", time(), ts); } Output: 1046227356 1046227357 The first number expected to be greater than second. If I insert "count++" into while loop (instead of empty body) everything is OK. This problem doesn't occur when time() is called indirectly. And, whatever it is, optimization of this kind is a bit weird, IMHO... :) Regards, /Al

Calling Pike functions with variable number of arguments from C
by Marek Habersack 25 Feb '03

25 Feb '03

Is it as simple as pushing all the required parameters to the stack and then calling the Pike function as usual? (i.e. with apply_svalue or apply_low) TIA, marek

Postgres support bug?
by Leif Stensson, Lysator ＠ Pike developers forum 22 Feb '03

22 Feb '03

I've tried using the Postgres module a bit lately, and now I've stumbled across an odd behaviour: db->list_fields(table_name) throws an error "Error in frontend-backend communications.". This seems to be caused by the list_fields() function assuming that the "pg_class" table always has a "relexpires" columns, which is not the case in the Postgres database I'm connecting to. Should there always be a "relexpires" column in the "pg_class" table in a Postgres database (that is, is the one I'm connecting to buggy?), or is Pike just making in incorrect assumption?

Problems with pike -x module
by hww3 ＠ Pike developers forum 21 Feb '03

21 Feb '03

I'm trying to work my way through the external module building process, and I figured I'd start with one of the internal pike modules, to be built outside the tree. I copied the Math module someplace nice and ran this command: pike -x module --source=. and this is what I get: $ cd /tmp/Math $ pike -x module --source=. autoheader WARNING: Using auxiliary files such as `acconfig.h', `config.h.bot' WARNING: and `config.h.top', to define templates for `config.h.in' WARNING: is deprecated and discouraged.

MacKenzie and Akim Demaille. Obviously something is not right here, but I don't know enough about autoconf to know what might be the problem. I believe it has something to do with the aclocal.m4 in the include/pike directory, but I don't want to fiddle with that if I don't have to. I'm testing on a solaris 7 box with autoconf 2.54 and gm4 1.4. Any ideas? Bill

Failed tests again (v7.4.15/CVS 2003-02-21)
by Alexander Demenshin 21 Feb '03

21 Feb '03

Hi all, Just tried latest CVS (v7.4.15), it still doesn't pass test suite completely, and again because of Calendar (mostly) module, however everything else is perfectly OK. Perhaps someone could look at the results and tell me what might be wrong? http://aldem.net/pike/failed I just cannot believe that this problem is related to Slackware Linux only... And I need this damn SSL module, which is dependent on Calendar :) Thanks, /Al

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?
