trace(1)
by Martin Nilsson (har bott i google) ＠ Pike (-) developers forum 19 Mar '03

I think I would like to see a shift in trace levels, making trace(1) only print out the file and line executed.

Module namespace
by Niels M�ller () ＠ Pike (-) developers forum 13 Mar '03

13 Mar '03

I have split the nettle module in two files, and need to share some symbols between them. Is it ok to have non-static functions like "hash_init" and "hash_exit" in a module, or do I need to use some more obfuscated name? Is there any nice convention for the names of the initialization function of Nettle/hash.cmod?

INIT order
by Niels M�ller () ＠ Pike (-) developers forum 13 Mar '03

13 Mar '03

If I have an inheritance tree, with INIT methods in each class, in which order will they be invoked when a class is cloned? In particular, when using multiple inheritance class foo { inherit A; inherit M; } can I count i on A's INIT method being executed before M's? For some context, M is a mixin, that works by initializing fields of A. Inheritance tree may look something like M A N | | | | B | | |\ / | C E \ / D where N and M are two different mixins modifying the behaviour of A.

Inherit in .cmod
by Niels M�ller () ＠ Pike (-) developers forum 13 Mar '03

13 Mar '03

I'm having some trouble, I get a segmentation fault in f_function_name, which I'm not sure how to debug. First, I'd like to know if the inheritance works correctly, the below is the generated code. If I hade written it by hand, I would have put the ADD_STORAGE after the low_inherit calls. #ifdef PROG_MD5_STATE_ID START_NEW_PROGRAM_ID(MD5_STATE); #else start_new_program(); #endif /* PROG_MD5_STATE_ID */ #ifdef THIS_MD5_STATE md5_state_storage_offset=ADD_STORAGE(struct md5_state_struct); #endif /* THIS_MD5_STATE */ #ifdef inherit_hash_instance_md5_state_defined low_inherit(hash_instance_program, NULL, -1, 0, 0, NULL); #endif /* inherit_hash_instance_md5_state_defined */ #ifdef inherit_nettle_md5_md5_state_defined low_inherit(nettle_md5_program, NULL, -1, 0, 0, NULL); #endif /* inherit_nettle_md5_md5_state_defined */ #ifdef md5_state_event_handler_defined pike_set_prog_event_callback(md5_state_event_handler); #endif /* md5_state_event_handler_defined */ md5_state_program=end_program(); add_program_constant("md5_state",md5_state_program,0);

autoconf
by Niels M�ller () ＠ Pike (-) developers forum 13 Mar '03

13 Mar '03

Jag kör med autoconf-2.57, vilket verkar fungera modulo diverse varningar från både pike och autoconf. Men nu får jag såna här fel cd /home/nisse/hack/pike/src/post_modules/Nettle && autoconf --localdir=/home/nisse/hack/pike/src autoconf: invalid option --localdir=/home/nisse/hack/pike/src Vad är det meningen att --localdir ska göra?

These functions seems to never have been checked in. Should I do that? Should they be named to_hex/from_hex, or string2hex/hex2string? / Niels Möller () Previous text: >2002-05-10 22:42: >Subject: nettle.cmod >-------------------------------------------------------------------- >Getting down to the optimal number of classes, and making the best use >of the hacks in nettle's nettle-meta.h. > >But I may be able to solve the problem in a better way once I get >inherit to work.

Module testsuites
by Niels M�ller () ＠ Pike (-) developers forum 12 Mar '03

12 Mar '03

How are module testsuites supposed to work? I've added a Nettle subdirectory, and run make force_Autoconfig, and recompiled. In the build dir, build/<system>/post_modules/Nettle, there's no testsuite file. When I run make verify, it complains Failed to read test file "testsuite", errno=2. make: *** [verify] Error 1 and when I run make testsuite, it says make: `../../testsuite' is up to date. Running touch testsuite && touch $src/testsuite && make testsuite seems to create a testsuite, though.
