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..?

class( ({"hello"})[*]) ?
by David Hedbor ＠ Pike developers forum 19 Apr '05

19 Apr '05

Why do I get an error in the second case, when it's the same thing except using an anonymous array rather than a named one? Pike v7.7 release 13 running Hilfe v3.5 (Incremental Pike Frontend) > array a = ({ "hello world" }); Regexp(a[*]); (1) Result: ({ /* 1 element */ Regexp.SimpleRegexp(hello world) }) > Regexp(({"hello world"})[*]); Compiler Error: 1:[*] not supported here.

Re: subversion bindings?

Yes! It worked. Now the server just has to wrap its mind around the notion that 0.106 is actually newer than 0.99 (see also "dewey decimal")...

Nope. My router does NAT for the machine in question, but that should not matter for HTTP.

refdoc extractor
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 11 Apr '05

11 Apr '05

Both in 7.6 and 7.7 I see dependencies on $(BUILDDIR)/modref.xml in refdoc/Makefile. But I can't find any rule that makes that file, and it's not in cvs either. How is it supposed to work?

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.

Protocols.DNS_SD.Service
by Jonas Walld�n ＠ Pike developers forum 10 Apr '05

10 Apr '05

I just checked in a first attempt at an interface for DNS Service Discovery in Pike 7.7. This lets Pike programs register services so that Rendezvous/Zeroconf-aware applications on the same network can see them. For example, I plan on using it to announce web servers and have them show up as Safari bookmarks automatically. The current implementation is designed to work with Mac OS X 10.3 or later as well as Linux (using libhowl). However, I don't have a Linux machine with the developer package of libhowl installed so I'm sure some tweaks will be needed for it to compile correctly. A natural step forward would be to design a Protocols.DNS_SD.Browser class next. This can be a bit trickier depending on what type of API the high-level code should have (e.g. async callbacks or just a snapshot of the currently available services). If anyone feels like helping out it would be great! (BTW, thanks to Grubba for adding the missing testsuite.in to fix the yellow blupps in Xenofarm.)

utf8_to_string crippling
by Peter Bortas ＠ Pike developers forum 08 Apr '05

08 Apr '05

I'm not convinced that I like the utf8_to_string crippling. I can see why you don't want to do it in a lot of applications, but how do I decoce the non-shortest form with this change?

utf8_to_string crippling
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 04 Apr '05

Decoding such malformed surrogate sequences does not affect the ability of an application to treat ASCII characters without decoding UTF though, which if I understood correctly was the only reason for the extra stringency in the decoder...
