verify failure (not catched by xenofarm testsuite)
by Alexander Demenshin 03 Mar '04

03 Mar '04

Hi, I got the following: /home/aldem/src/Pike/Pike7.5-20040229-221338/src/testsuite.in:10137: Test 10355 (shift 2) (CRNL) produced warning. 0: Decode failed: Got unfinished program <18> after decode: program(/home/aldem/src/Pike/Pike7.5-20040229-221338/src/test-install/pike/7.5.19/lib/modules/Protocols.pmod/HTTP.pmod/Server.pmod/Request.pike) Is it fatal? Or I can safely ignore it? Regards, /Al

valgrinding Pike - some problems
by Alexander Demenshin 03 Mar '04

03 Mar '04

Hi, Just attempted to valgrind recent version (from CVS), immediately got thousands of errors like this: ==7875== Conditional jump or move depends on uninitialised value(s) ==7875== at 0x81B5AF7: debug_check_node_hash (las.c:830) ==7875== by 0x81506F1: optimize_binary (operators.c:1712) ==7875== by 0x81C8A04: optimize (treeopt.h:3289) ==7875== by 0x81CCCF3: optimize_node (las.c:5363) Where is the catch? It seems that entire structure is initialized correctly upon allocation (there is a call to MEMSET)... What makes me curious, though - is - where alloc_node_s() is defined? Grepping all files in src/ gives single match - call to this function, object file symbol table says that alloc_node_s() is defined in las.c, but... Regards, /Al

hi, first of all, thanks for the invitations i have received, i hope to be able to follow them some time. a few days ago i arrived in latvia and i am already spending my time here helping out with all sorts of pike problems. this evening i'd like to invite everybody in or near riga who is interrested in pike to get together for an informal discussion on how we can make the best use of my time here in latvia, to teach and present pike. we will be planning tutorials and presentations according to need and interest. there are no requirements to participate (just interest in pike :-) the meeting location is in the offices of interneta pasaule Kr Barona 24/26 (3rd floor) (near vermanes parks) in riga suggested meeting time is around 7pm. looking forward to seeing you there. greetings, martin. ps: please pass on this message as you see fit. -- looking for a job doing pike programming, sTeam/caudium/pike/roxen training, sTeam/caudium/roxen and/or unix system administration anywhere in the world. -- pike programmer travelling and working in europe (latvia) open-steam.org unix system- bahai.or.at iaeste.(tuwien.ac|or).at administrator (stuts|black.linux-m68k).org is.schon.org Martin Bähr http://www.iaeste.or.at/~mbaehr/

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
