Access to default `->() in C modules
by Alexander Demenshin 01 Mar '04

01 Mar '04

Hi, I would to implement [kind of] properties in C module, so it will be possible to access some variables like obj->prop. I tried map_variable() first, but it doesn't work well - it's value can be changed outside of object (may be there is an attribute to disable this?), and - it cannot be (safely) extracted with get_all_args() - since size of Pike's int/float is not necessary same as size of C int/float (and I don't want to use Pike types everywhere in C data structures). So... The logical way is to implement `->() function, but I don't know how to do this in C (not exactly). In Pike, I can use something like ::`->() to call predefined (original) indexing operator, so what should I do in C? Or, more precise, how? Regards, /Al

Problem with function prototypes
by Alexander Demenshin 29 Feb '04

29 Feb '04

Hi, Doing some tests, I discovered interesting behavior... Say, we have the following: class Test { string method(int n, string s) { // ...blabla } } And some declarations: Test typed = Test(); object untyped = Test(); So now, when I try to call typed->method(), the prototype will be checked, but when I call untyped->method(), it won't (and all arguments will be 0). As I understand, this is exactly because of absense of type declaration in latter case, but... Is it intended to behave like this? Sure, run-time prototype checking is expensive, but... It's absense may lead to some strange application behavior, especially in C module (do I've to call pop_n_elems(args) regardless of function prototype?). After all, it places responsibility to check all arguments to the developer, explicitly (so it has to be done anyway). Concerning C modules... I have something like this: void object_match(INT32 args) { struct pike_string *s; // ... get_all_args("match", args, "%S", &s); // ... } And prototype defintion like this (in pike_module_init()): add_function("match", object_match, "function(string:int)", 0); So, when this method is accessed through generic typed variable (object re) without arguments, I get segfault in 7.5, while in 7.4 everything is OK (error is thrown with no [visible] side effects). I wonder what will happen if function will be called with arguments while it accepts none (and there is no pop_n_elems(args) call)... Do I do something wrong? Or this is a bug somewhere? Regards, /Al

CVS access
by Alexander Demenshin 28 Feb '04

28 Feb '04

Hi, If possible, I would like to have write access to Pike's CVS. Primary goal - fixes to obvious (and sometimes not), like recent problem with get_all_args(). Yes, I've read and agreed to the policies, and I promise not to do any significant (or potentially dangerous) changes without prior discussion on the list. Regards, /Al

More 7.4/7.5 differences (C modules)
by Alexander Demenshin 28 Feb '04

28 Feb '04

Hi, Just another difference... Before (7.4), just using add_function() in pike_module_init() was enough to make it constant (i.e. visible through indices() and accessible by Module.func()). In 7.5, however, it is not the case - so anything that is added with add_function() is not visible (and not accessible). Is it right - so add_function_constant() should be used (I just want to make minimum changes to existing modules, while migrating to 7.5). Regards, /Al

modules in C++?
by Alexander Demenshin 27 Feb '04

27 Feb '04

Hi, Is it safe (or possible) to write modules in C++ instead of C? I don't any C++-safe declarations (extern "C") in Pike headers, so it seems - not... Do I miss something or? Regards, /Al

Nettle
by Martin Nilsson (saturator) ＠ Pike (-) developers forum 26 Feb '04

26 Feb '04

I PUSHED THE BUTTON. Now the _Crypto module isn't used (though still built). That means that you'll need Nettle installed to use any parts of Pike that uses Crypto.

7.4.44
by Martin Nilsson (saturator) ＠ Pike (-) developers forum 26 Feb '04

26 Feb '04

Peter and I have been working hard with resolving some NT problems and have now managed to create a new NT dist with pretty much everything except GLUT. 7.4.44 source dist and windows dist are available in FTP. Release notes at http://pike.ida.liu.se/download/notes/7.4.44.xml We'll release it more publicly when we have binary dists for more platforms. Please help out with good binary dists.
