Redirecting stdio
by Kaos 26 Oct '04

26 Oct '04

Howdi gurus :) I'm trying to redirect my stdin/stdout/stderr when using Process.create_process. This far, I only get data through first when the file gets closed. I would much prefer to have them in a non-blocking fashion - any way to get this? (tried PROP_NONBLOCKING and set_nonblocking( read_cb, write_cb ) without success... )...

cmod vars to pike
by Kaos 25 Oct '04

25 Oct '04

Hi, How do I go about to map variables from a cmod to pike? I've found map_variable( "name", "type", flags, offset, pike_type ) but it comes along with a few questions. Can I only map struct object|string|array|... stuff from my Foo_program struct, or c stuff as well? like a foo * (or foo[]) treated as an array (guess not, so I'm about to make a struct array of my foo[]).. I'm only needing it for read only, but what happens if written to?

Another one.. simply a missing ')' when generating GET_[FOOBAR]_STORAGE about line 1639 (v7.6). Guess no-one use to use this macro, eh ;P

stralloc

If the dnl-prefixed lines in SQLites testsuite is enabled and the testsuite is run, Pike hangs in internal_findstring in stralloc.c. With dmalloc I get **Block: 0x97c7090 Type: string Refs: -1 **size_shift: 2, len: 1, hash: b31e0f9c Locations that handled 0x97c7090: (gc generation: 1/1 gc pass: 0/0) *** /home/nilsson/Pike/7.7/src/builtin_functions.c:1505 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:718 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:5455 sub_ref (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:253 sub_ref (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:2007 sub_ref (2 times) *** lexer0.h:672 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/interpret_functions.h:297 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:1179 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/mapping.c:747 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/program.c:5239 add_ref (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:698 add_ref (2 times) --> /home/nilsson/Pike/7.7/src/post_modules/SQLite/testsuite.in:55: Test 18 (shift 0):0 (1 times) *** /home/nilsson/Pike/7.7/src/builtin_functions.c:1505 (2 times) *** /home/nilsson/Pike/7.7/src/las.c:5455 (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:2007 (2 times) *** /home/nilsson/Pike/7.7/src/post_modules/SQLite/sqlite.cmod:220 (2 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:385 (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:535 (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:1405 (1 times) *** lexer0.h:672 (2 times) ******************* Is this a problem with stralloc?

I just fixed a few ref count bugs I noticed after a quick look.

Facets
by Martin Nilsson (DivX Networks) ＠ Pike (-) developers forum 23 Oct '04

23 Oct '04

Mikael Amborns facet implementation is finally checked into Pike. Facets allows you to enforce that a multiple inheritance is used when functionality is split into several classes. One current misfeature is that the facet group object needs to exist before (e.g. loader wrapper) or be created during compilation (e.g. .pmod file). Usage example: > add_constant( "Bunny", FacetGroup() ); (1) Result: 0 > class White { facet Color:Bunny; } > class Black { facet Color:Bunny; } > class Small { facet Size:Bunny; } > class Large { facet Size:Bunny; } > class Snuffy { inherit White; inherit Small; } > class Sooty { inherit Black; } Compiler Error: 1:Error in some product classes Compiler Exception: Product class does not inherit from all facets. _static_modules.Builtin()->facet_group: _static_modules.Builtin()->facet_group()->check_product_classes() > class Checkers { inherit Black; inherit White; } Compiler Error: 1:Unable to add product class Compiler Exception: Product class can only inherit from one class in every facet. _static_modules.Builtin()->facet_group: _static_modules.Builtin()->facet_group()->add_product_class(65713,0,65701) Another problem is that it leaks all kinds of stuff (parser stack, objects and strings)...

Bug in precompile.pike
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 22 Oct '04

22 Oct '04

There seems to be a bug in precompile.pike in 7.7. I checked out a fresh copy from CVS this morning and it failed to compile the SQLite module which Nilsson checked in last night. I looked at the code and found that on line 145, it does store = GET_RESOBJ_STORAGE(res); which the C-compiler later complains about. Some investigation shows that precompile.pike gives the following define for that macro: #define GET_RESOBJ_STORAGE ((struct ResObj_struct *)(o->storage+ResObj_storage_offset) which is almost the same as the OBJ2_RESOBJ macro, besides that OBJ2_RESOBJ takes a parameter (o) and has balanced parenthesis. I do not understand the intended difference between these defines and thus I will leave it up to someone else to sort this out. For now, I'll change the code inte SQLite module to use the OBJ2_RESOBJ() macro.

C documentation
by Martin Nilsson (DivX Networks) ＠ Pike (-) developers forum 21 Oct '04

21 Oct '04

One topic discussed at the Pike Camp was documentation. With the beginners book just around the corner and the module tree documentation almost complete, the lack of documentation of the C API was deemed the most important area to improved. Thus we decided to immideatly try out doxygen for this, and as an experiment we documented array.[ch] and generated this: http://pike.ida.liu.se/generated/manual/c_api/html/index.html To not clash with autodoc, only the /** syntax is used, and not the /*! one. Comments?

Ncurses
by Kaos 19 Oct '04

19 Oct '04

Howdi, I've tried to make a relase on modules.gotpike.org, but it keeps saying I've not provided any source when uploading my tar-archive. So, anyone interested to see what've been done this far, please use the following link: http://kaos.explosive.se/files/Stdio_Ncurses-0.4.tar.gz There's still alot to do.. but basic operation of ncurses should work. Tested (somewhat) on both 7.6.25 and 7.7.9. For a compiled refdoc, refer to: http://www.explosive.se/~kaos/doc/ncurses/ex/predef_3A_3A/Stdio/Ncurses.html // Andreas
