Sql typed mode
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 07 Mar '11

07 Mar '11

I made some incompatible changes in the so-called typed mode for Mysql, both in 7.8 and 7.9. It only concerns the somewhat less used BIT and DECIMAL types, and it's not a compat problem if one only considers the last official 7.8 release, but otoh it's a change from what's been in git the last 1½ years. (I also updated CHANGES while I were at it.)

CritBit-Tree implementation for pike
by Tobias S. Josefowitz 03 Mar '11

03 Mar '11

We have been working on a CritBit tree implementation for pike. We would like to get it upstream, however we have made a few changes elsewhere that may need discussion: precompile.pike templating: we added a simple template support to precompile.pike. It basically replaces a set of identifiers in the template file before precompilation. The syntax is admittedly not very beautiful. Autodoc to support global paths in AUTODOC_SRC_IN: we could not figure out how to make the autodoc generator to extract docs from several .cmod files without the AUTODOC_SRC_IN feature applied on the generated .c-files with absolute paths. You can check it out using git from http://fortranland.com/git/pike. The branch is called critbit. We have not done any testing on non x86 machines. It would be nice if someone could run the testsuite on some big endian machine. Also, we only compiled on linux machines. There might be problems on other environments because of the gcc intrinsics we are using for prefix searches. Currently there are trees supporting float, integers and pike strings and two derived types for ipv4 ip addresses and date objects. The lookup, insert and delete operations are comparable in speed to pike mappings (1.X slower in our tests). In worst case scenario critbit trees can be slow in insert and lookup (e.g. keys like "a"*i). However, critbit trees should be more memory efficient in many cases because of the mapping overhead. Also, they support several operations that mappings don't offer, namely, iteration in lexicographical order, range lookup and finding biggest/smallest index, etc. We have written quite extensive tests and a complete documentation, which you can find at http://fortranland.com/refdoc/modref/ex/predef_3A_3A/ADT/CritBit.html Any hints, suggestions, bugreports and comments are welcome. arne and tobias

Documentation diff
by Matthew Clarke 03 Mar '11

03 Mar '11

Hi Please find attached some documentation for Pike's SDL module. I commented out the declaration of the SDL_Surface variable at the head of the PIKEFUN for SDL.set_video_mode() and everything still worked. I don't think it gets used, but is redeclared inside the following if...else statement. Thanks :)

configure and defines
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 26 Feb '11

26 Feb '11

Perhpas more a philisophical question, but do we really need configure tests for .h file defines. I just saw masts commit of testing for the existance of FIELD_TYPE_BIT and then doing #ifdef HAVE_FIELD_TYPE_BIT case FIELD_TYPE_BIT: #else case 16: #endif wouldn't no configure test and a #ifndef FIELD_TYPE_BIT #define FIELD_TYPE_BIT 16 #endif had had the same result?

Key padding AES
by Coen Schalkwijk 03 Feb '11

03 Feb '11

Hi, I have some trouble with sharing AES encrypted data between pike 7.4 and 7.8. I think this is because the 7.4 key is somehow of size 32 (whilst offering a 16 char key) and the 7.8 sticks to a key size of 16. With what is the 7.4 key padded to end up with a key sized 32? -- Met vriendelijke groet / With kind regards / mit besten Grüßen, Coen Schalkwijk Software Engineer coen.schalkwijk(a)rtl.nl <mailto:coen.schalkwijk@rtl.nl> coen(a)rtlinteractief.nl <mailto:coen@rtlinteractief.nl> +31 (0)35 671 8915

Standards.URI
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 02 Feb '11

02 Feb '11

Regarding the checking "Standards.URI: More paranoid handling of ..-segments that reach past the root.": Is the semantics of the path segment declared somewhere? If not we shouldn't probably do sanity checking/normalization of it in Standards.URI.

SDL.get_video_info() docs
by Matthew Clarke 31 Jan '11

31 Jan '11

Hi Slow week again :( but I got this one function done. I haven't changed the return type but I'm sure it's not right. It's given as void|object but I can't see how it would ever not return anything. If the video device is uninitialized, Pike returns 0 (the original C function returns NULL). Wouldn't that be a special type of (null) object rather than void? Thanks & regards, larcky.

'make doc' doesn't work
by Matthew Clarke 23 Jan '11

23 Jan '11

Hello I hope this isn't just my machine that's playing up because I'm using my netbook at the moment rather than my main PC, but... With the latest Pike checked out from git, 'make doc' fails with this error message: PikeParser: expected identifier, got "(" (/home/matthew/Downloads/Pike-devel/pike/src/builtin.c:5611) Hope someone can make sense of that! Regards, larcky P.S. no problems at all with 'make' and 'make install'

SDL
by Matthew Clarke 23 Jan '11

23 Jan '11

Hi Not done much this week but here's some documentation for SDL.blit_surface(). I've left out some of the subtleties in the original C docs and just filled in the basics. I hope I'm right in changing the method signature: I had a look at the PIKEFUN in SDL.cmod and tried out a small example and it seems you can set those last two args (srcrect & dstrect) to '0' or leave them out to get default behaviour. Also, with SDL.Rect, is this the only way you can initialize an SDL.Rect object to, say, values 50, 50, 100, 100? SDL.Rect r = SDL.Rect(); r->x = 50; r->y = 50; r->w = 100; r->h = 100; Before I tried this: SDL.Rect r = SDL.Rect( 50, 50, 100, 100 ); but it didn't compile, presumably because there's no create() method matching that pattern? Would that be a useful thing to add, or is there a smarter way of setting the initial values? Thanks and regards, larcky :)
