Re: Need another GC policy
by H. William Welliver III 22 Apr '07

It's probably worth noting that the Java garbage collector does suffer from many of the same problems, even if there are no "scheduled" runs. The main problem here is that the gc runs in a "stop the world" fashion. I'm not sure if that can be avoided completely.

GLUE
by Mirar ＠ Pike developers forum 17 Apr '07

17 Apr '07

Now I'm missing GLUE.Font, base/Font.pike:14:Index Font not present in module "GLUE". base/Font.pike:14:Illegal program identifier: 0. base/Font.pike:42:Index Font not present in module "GLUE". base/Font.pike:44:Index Font not present in module "GLUE". base/bumpy.pike:14:Error looking up 'Font' in module '.'. I didn't see GLUE change when I updated, and it's in there in module.pmod. What up?

Should I assume Pike 7.7 is so severly broken it's no use trying to get it to work?

I suspect these problems depend on the new typechecker... bin/mkpeep.pike:463:Too many arguments to sprintf. bin/mkpeep.pike:463:Expected: function(string(8), int(0..2147483647) : string) bin/mkpeep.pike:463:Got : function(string(8), int, string : void | mixed) 463: buf->add_line( sprintf("%*n}", ind, test) ); Can't work around that. Copying an old peep.c, bin/precompile.pike:2006:Too many arguments to sprintf. bin/precompile.pike:2006:Expected: function(string(8), object | int, object | string, object | int, object | string : string) bin/precompile.pike:2006:Got : function(string(8), int, string, int, string, string : void | mixed) 2006: PC.Token(sprintf("if(Pike_sp[%d%s].type != PIKE_T_STRING || Pike_sp[%d%s].ustring -> width)", 2007: argnum,check_argbase, 2008: argnum,check_argbase, 2009: upper_case(arg->basetype())),arg->line()) This is true, however I don't think "too many arguments to sprintf" should be an error, but a warning, unless it's strict_types. (But that's my personal opinion.)

sprintf() arguments now type checked in Pike 7.7.
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 13 Apr '07

13 Apr '07

I've added some type checking support for sprintf() arguments: New type checker: > sprintf("%s%i%f\n", 17, "", 14.0); Compiler Error: 1:Error in format string, i is not a format. Compiler Error: 1:Bad argument 2 to sprintf. Compiler Error: 1:Expected: object | string Compiler Error: 1:Got : int(17..17) Compiler Error: 1:Bad argument 3 to sprintf. Compiler Error: 1:Expected: object | float Compiler Error: 1:Got : string(0) Compiler Error: 1:Too many arguments to sprintf (expected 3 arguments). Compiler Error: 1:Got : float Old type checker: > sprintf("%s%i%f\n", 17, "", 14.0); Compiler Error: 1:Error in format string, i is not a format. Compiler Error: 1:Too many arguments to sprintf. Compiler Error: 1:Expected: function(string(8), object | string, object | float : string) Compiler Error: 1:Got : function(string(8), int(17..17), string(0), float : void | mixed)

New function call type checker for pike
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 01 Apr '07

01 Apr '07

Those who have monitored the Pike 7.7 CVS the last week or so, may have noticed a few new type checking related functions. These are intended to replace the current style of type checking where a function type for the current call is created and then compared in one pass against the declared type. This has led to somewhat cryptic error messages. eg: > `+((["":14]), "", 14); Compiler Error: 1:Bad argument 2 to `+. Compiler Error: 1:Expected: !function(!(object | mixed) ... : mixed) & function | function(int, int ... : int) | !function(!float ... : mixed) & function(int | float, int | float ... : float) | !function(!string ... : mixed) & function(string | int | float, string | int | float ... : string) | function((0=array), (1=array) ... : 0 | 1) | function((0=mapping), (1=mapping) ... : 0 | 1) | function((0=multiset), (1=multiset) ... : 0 | 1) Compiler Error: 1:Got : function(mapping(string(0):int(14..14)), string(0), int(14..14) : void | mixed) The new code is instead based on checking the arguments one at a time, but this means that the error in the above case is first detected when the last argument is checked: Compiler Error: 1:Bad argument 3 to `+, got int(14..14), expected object. This problem can be reduced by also adding warnings about prior arguments in case of the above error: Compiler Warning: 1:Potentially bad argument 2 to `+, got string(0), expected mapping | object. The question is what text the warning should have.

Hmm... Seems to work even for the more obscure cases: > typeof(class{}); (4) Result: function( : object(is HilfeInput()->__class_65709_0_line_1)) > typeof(Stdio.Stat()); (5) Result: object(is _static_modules.files()->Stat) Note that it will fall back to the old syntax if it fails to look up the program id: > _typeof(compile_string("")); (6) Result: function( : object(is 65723)) > mixed x = compile_string(""); > _typeof(x); (7) Result: function( : object(is -))
