negative indices in array ranges
by Mirar ＠ Pike developers forum 06 Mar '03

Doesn't filter already copy depending on a multiset or an array? Maybe filter_range could be suitable for a copying-by-range function.

decoder for utf-8
by rjb ＠ Pike developers forum 06 Mar '03

06 Mar '03

How is the decoder returned by Locale.Charset.decoder("utf-8") supposed to behave when fed a bytestream that is not valid UTF-8? It seems to return some peculiar results, instead of throwing an error (like utf8_to_string quite correctly does): > object dec = Locale.Charset.decoder("utf8"); > dec->feed("\xc0\xc0")->drain(); (62) Result: "@" > utf8_to_string("\xc0\xc0"); utf8_to_string(): Expected continuation character at index 1 (got 0xc0).

I am trying the following code in a simplistic telnet server. ----- constant pLogin = (program)"login.pike"; void telnet_connection(object oConnection) { telnet_class(oConnection); //New connection object pLogin oLogin = pLogin; oConnection->set_interface(oLogin); } ---- Continually I get returned: Attempt to call the NULL-value Unknown program: 0(c:/blah/sys/obj/inherit/login) Basically alls I want it to do is connection, make a unique object for each connection, then move that connection to another object that asks questions and such ... anyone able to help me out?

endcut() could even work destructively on arrays. :-)

Pike 7.4.10 vs Pike >= 7.4.14
by Xavier Beaudouin 05 Mar '03

Hey, Inside Caudium 1.3, I have some code like this : Caudium.pmod/HTTP.pmod the top level directory where Caudium.pmod is added to Pike Module Path Inside HTTP.pmod I have : string make_html_doc_string () { return "foo"; } Somewhere in this code I have string plonk () { return Caudium.HTTP.make_html_doc_string(); } On Pike 7.4.10 this works like a charm. On 7.4.14 and more this fails with : Loading Caudium ... error: /${PIKE_MODULE_PATH}/Caudium.pmod/HTTP.pmod:205 Error: Index 'make_htmldoc_string' not present in module 'HTTP'. I really suspect a bug somewhere inside the Pike 7.4 code but I cannot find where it is located. Any clues ??? Note that reverting to Pike 7.4.10 fixes the problem.... /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader.

Name of ADT
by Peta, jo det �r jag ＠ Pike developers forum 05 Mar '03

05 Mar '03

I've completed a new ADT, but have some problems with what to name It to. It is basically a Sequence, see w1.313.telia.com/~u31318241/CommonAPI.pdf for my definition of a Sequence (basically an array where you can do insert and remove). The suggested names are -ADT.Vector -ADT.Array -ADT.Sequence I'm personally leaning towards Vector or Sequence because Array could cause name conflicts. The ADT is currently named ArrayAdapter (not a very good name).

Children and Clones

> Programs will however always have a parent pointer when they aren't > on the top level in a compilation unit. Sorry, that could easily be misinterpreted. It should be: Programs will always have a parent pointer when they aren't the top level in compilation units.

Children and Clones
by kaylus ＠ Pike developers forum 04 Mar '03

I was wondering something. I read that Pike keeps linked lists for all objects/programs/functions/etc. and I also noticed that you can use _prev() and _next() to iterate through these. I wanted to know if there was other ways to traverse these lists. To get down to it, what I need is a way to find all the children of a specified object, and a way to find all the clones of a specified object. Currently the only way I can think about doing it is using programs and that is backwards: create a blank array, iterate through the list of programs, check what it inherits, save the pointer to the program in the array if it inherits Obj X, iterate again, etc. until through the whole list. That just seems too much to me. Any help would be appreciated. Thanks Kaylus

Too few

fum.pike:390:Too few arguments to get_url_data. fum.pike:390:Expected: function({ URI = object(implements 65828) } | string, mapping | void : string) fum.pike:390:Got : function(object(is 65847), mapping(string:string) : void | mixed) Let's see. One, two. One, two. Am I or Pike insane here? I could possibly accept "illegal argument 1", but...
