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?

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.

Recursive module dependency
by Ludger Merkens 11 Mar '03

11 Mar '03

Hi again, What exactly is the meaning of the Error Message: Recursive module dependency in 'ModuleName' It occurs only if I write a class in a module, that holds instances of its own class. (a parent variable e.g.) Addidtionally it occurs only with my own master, so my main question is probably what may have gone wrong (probably during lookup) that this behaviour occurs. What did i do in the master? (next to some other stuff) *) change master_file_stat that filenames starting with "/" will be prefixed with some "fakeroot" *) make compile_file,read_include, master_read_file aware of this. I also notice, that in the programs cache are empty instances of prefix/path/to/Modulename but compile complains about path/to/Modulename having "recursive module dependencies". hints are welcome. --- Ludger

pike master fakeroot()
by Ludger Merkens 11 Mar '03

11 Mar '03

Hi, I'd like to use the fakeroot() mechanism implemented in the pike master for the sTeam Server. Is there a way from outside the master.pike to make use of this feature? Basically I don't want to change the master, but use the feature. If it is necessary to replace the master, thats fine as long as I may inherit the pike master. help appreciated. --- Ludger
