creating Objects
by Sebastian Kaminski 28 Mar '05

28 Mar '05

hi, I need to create an instance of a class on C-level. I assume I have to allocate memory for the data used by the object. Do I do that directly or are there any macros/functions thath I ought to use. Another problem is that the class that I want to instantiate doesn't contain any data itself (only functions), but one of the classes it inherits does have data; how do I link this? - Sebastian

Pike 7.7, modules -> post_modules
by David Hedbor ＠ Pike developers forum 26 Mar '05

26 Mar '05

Of course, none of that matters since backend is also a cmod... I guess it's impossible to compile pike without pike and thus I suggest that post_modules is deprecated since they no longer have a purpose.

GC hang

With the new pike parser code "make doc" hangs (at least for me). It appears to be stuck in gc_cycle_check_all_arrays().

Inactive optimizer.

If I make a program that contains float x = limit(0, 1, 2); I will, as expected, get C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Bad type in assignment. C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Expected: float C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Got : int(1..1) i.e. the run time type of the limit expression is not compatible with the type of the variable x. If however I change the code to int x = limit(0.0, 1.0, 2.0); I will instead get C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Bad type in assignment. C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Expected: int C:/MinGW/home/Nilsson/Pike/7.7/foo.pike:5:Got : float | float | float i.e. the compile time type of the limit expression. Why not the run time type?

precompile.pike overflow in polymorphic functions
by Bill Welliver 21 Mar '05

21 Mar '05

I've run into a problem with the precompile.pike from 7.6.24 while trying to use polymorphic function overloading. I've got the following methods: PIKEFUN object set_a(string a, string b, string c) ... PIKEFUN object set_b(string a, string b) but precompile goes into a loop which results in a stack overflow. Here's a portion of the stacktrace: /usr/local/pike/7.6.24/include/pike/precompile.pike:1330: /usr/local/pike/7.6.24/include/pike/precompile()->generate_overload_func_f or(({@011111,@111111}),5510,0,2147483647,"set_a",@211111) Any suggestions?

papers on pike
by Martin Bähr 21 Mar '05

21 Mar '05

hi, the following message reached us at the pike conference email address. do you guys have any papers to help them out? ----- Forwarded message from Sean Kugele ----- Hello, I am a graduate student at Virginia Polytechnic Institute and State University. A fellow student and I are giving a presentation on the Pike programming language and would like to obtain a journal article or a conference paper about Pike. So far we have not had much luck finding anything on the Internet, so we would greatly appreciate any help you could offer us in this endeavor. The presentation given by Dr. Uwe Assmann on Pike as a bridge between UML and Java would be perfect if you know where we could obtain a write up of this presentation, or perhaps if there exists a thesis on Pike that illustrates some of the language's design goals... ----- End forwarded message ----- greetings, martin. -- cooperative communication with sTeam - caudium, pike, roxen and unix offering: programming, training and administration - anywhere in the world -- pike programmer travelling and working in europe open-steam.org unix system- bahai.or.at iaeste.(tuwien.ac|or).at administrator (caudium|gotpike).org is.schon.org Martin Bähr http://www.iaeste.or.at/~mbaehr/

pikefarm
by Marc Dirix 19 Mar '05

19 Mar '05

Anyone recently looked at pikefarm 7.7? Something is going wrong with the testsuite. Most dots are yellow. The failing test has to do (as far as I can see) with the LDAP tests, which should actually be skipped because ldap support wasn't build in. Thnx, Marc

xenofarm, 1 down 1 to go.
by Marc Dirix 16 Mar '05

16 Mar '05

As stated xenofarm reports 2 errors. IMO this one is a bit harder. Pike version=7.7.13 The problem fails in running test_resolve.pike. Pike segfaults. After logging I found the program to fail with one file. If I remove the file with which this occurs (FIPS10_4.pmod) it doesn't segfault anymore. When using hilfe, the same error occurs: > master()->resolv(Standards.FIPS10_4.pmod); Segmentation fault This *only* occurs on my sparc64 (debian) and not on a i386. I've created an test-program which inherits Standards.FIPS10_4 it also segfaults. I've attached an strace on this process which I've included as attachment (hope it helps). I can send more debugging info if necessary, but I have no clue where to go next. Best regards, Marc
