Pike string hashing
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 20 Apr '05

20 Apr '05

I'm a bit curious about the string hashing algorithm used in Pike. What algorithm is it based on and what complexities does it exhibit? Was it selected at random or is there some rationale behind it..?

MySQL big_query in 7.7
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 10 Apr '05

10 Apr '05

I think the new streaming behavior in Sql.mysql.big_query is nice and as it should be, but it's causing too much headaches in existing applications - the old de-facto behavior is too ingrained. So a proposal is to instead do like this: query: Like today - slow and memory consuming. big_query: A variant of query() that still is nonstreaming. I.e. it only avoids the very bulky response format of query(). streaming_query: Like big_query but guaranteed to stream if it exists. It's database dependent whether other queries can be issued while a streaming_query response object exists. It's of course also database dependent if there are locks on the tables in the server while the response object exists. While at it, we could also consider generalizing the big_typed_query interface that the oracle module provides: big_typed_query: Like big_query but doesn't convert everything to strings. Integers and floats are kept that way, Date/timestamps are Calendar objects, there are objects for representing the NULL value for each type. streaming_typed_query: Streaming variant of big_typed_query.

ring, scope, tuple
by Martin Bähr 30 Jan '05

30 Jan '05

hi, while we are chatting on irc, martin is having a stroll through the pike core and he reported some interresting findings: he found that the typesystem has types that have not been implemented, like: ring, scope and tuple. now tuple i am familiar with from python, but the others don't ring ;-) a bell. hubbe or someone else who might know, can you enlighten us as to what the properties of these types would be? also, which properties does a tuple have, that i can't get from an array with two elements? greetings, martin.

basic types as classes
by Martin Bähr 30 Jan '05

30 Jan '05

hi, in order to facilitate creating classes that are derived from basic types, i have started to implement a class Mapping that is supposed to behave exactly like a real mapping. using http://pike.ida.liu.se/generated/manual/modref/ex/lfun_3A_3A.html as a guideline, i have implemented all functions that i believe a mapping needs to support. please tell me if there is anything missing or wrong. if i don't get any complaints i am looking for a good place to check this into pike cvs. would Mapping.Mapping be a good place for this? greetings, martin.

Re: ring, scope, tuple

Ok, bad example since that could be written as array(int)(3) instread, but array(int,string)(1) -> A pair of int and string

Horrible kludge in lib/modules/SSL.pmod/sslfile.pike

pmod compilation & inherits
by Kaos 27 Jan '05

27 Jan '05

Hi, Does anyone have any clue what I'm doing wrong here ? The directly involved files are: RemoteObjectModel.pmod/ module.pmod Proxy.pike Service.pike ServerObject.pike ClientObject.pike In proxy, I have a class that inherits ServerObject, which it fails for here. But if I change it from inherit .ServerObject; to inherit "ServerObject.pike"; // works nice but then there's the next problem: if I add another file in this directory and tries to access it from module.pmod with .Foo (i.e. for Foo.pike) it fails with the same error as below (but with different names, naturally) I've tried to build up a similar situation with simple files, and there it works just fine. Any clues? Pike version: 7.6.25 <side-issue> If I would like to use the `-> and `[] lfun's in module.pmod, how do I resolve the modules/programs further down the tree? tried to `return ::`->( arg )' but didn't seem to work.. </side-issue> (sorry for lengthy log, not sure what information is relevant and not...)

Compiler segfault

This confuses me somewhat. I added some code to URI.pike and gave one variable the wrong name and ended up with > Standards.URI; lib/modules/Standards.pmod/URI.pike:383:Undefined identifier m.

Bison 2.0 build issue
by David Hedbor ＠ Pike developers forum 26 Jan '05

26 Jan '05

I'm pretty sure this error comes from the use of bison 2.0 since a similar system that uses bison 1.875 works. Compiling language.c y.tab.c:382: error: two or more data types in declaration of `yyss' y.tab.c:500: error: two or more data types in declaration of `yyprhs' y.tab.c:568: error: two or more data types in declaration of `yyrhs' y.tab.c:762: error: two or more data types in declaration of `yyrline' y.tab.c:919: error: two or more data types in declaration of `yyr1' y.tab.c:1057: error: two or more data types in declaration of `yydefact' [...more of the same...] This in turn is caused by: #define short int The code contains statements such as: short int yyss; which of course gets turned into int int. The old version of bison generates code which uses "short" instead of "short int". What is the correct solution? Remove the define or post-process the file, replacing "short int" with "int" using sed or similar?
