Using low_allocate_array()s extra_space arg leaks mem?
by Adam Montague 06 Jul '06

06 Jul '06

If I do this: PIKEFUN array(array(string)) test() { struct array *a; int i; a = allocate_array_no_init(0, 10); for (; a->size < 10; a->size++) { ITEM(a)[a->size].type = T_ARRAY; ITEM(a)[a->size].u.array = allocate_array_no_init(2, 0); for (i = 0; i < 2; i++) { ITEM(ITEM(a)[a->size].u.array)[i].type = T_STRING; ITEM(ITEM(a)[a->size].u.array)[i].u.string = make_shared_string("foo"); } } RETURN (a); } Then it leaks memory. But if I add in an extra counter and do it like so: PIKEFUN array(array(string)) test() { struct array *a; int i, j; a = allocate_array_no_init(10, 0); for (j = 0; j < 10; j++) { ITEM(a)[j].type = T_ARRAY; ITEM(a)[j].u.array = allocate_array_no_init(2, 0); for (i = 0; i < 2; i++) { ITEM(ITEM(a)[j].u.array)[i].type = T_STRING; ITEM(ITEM(a)[j].u.array)[i].u.string = make_shared_string("foo"); } } RETURN (a); } Then everything is fine. It doesn't look like really_free_array() cares about malloced_size, just size? Adam

PCRE bundle
by H. William Welliver III 06 Jul '06

06 Jul '06

I was wondering what the possibilities of getting the PCRE library included as a bundle for source distributions of Pike. It seems as though it's presence would be a useful thing for people trying to wean themselves off another language, and I've found it handy a few times (and I'm generally anti-regexp). Simple regexps are nice, but are missing a lot of the standard features people typically associate with regular expressions. Any thoughts? Bill

INIT vs create and EXIT vs destroy in C modules
by Adam Montague 05 Jul '06

05 Jul '06

When creating C modules that are wrappers around 3rd party libraries, you often have to allocate some struct when the object is created, and free it when the object is destroyed. What is the right way to do this? Assuming we have: CVAR struct foo_struct *foo; Do I set foo = NULL in INIT, then foo_init(foo) in create? Or should I just be doing the foo_init(foo) in INIT? And when freeing it later, should I be doing foo_destruct(foo) in EXIT or in destroy? Also, when using CMODs INHERIT, do INIT and EXIT get inherited as well, or just PIKEFUNs PIKEVARs and CVARs? Thanks Adam

Pike with mingw

modifying an array argument in C modules
by Adam Montague 04 Jul '06

04 Jul '06

I am working on a C module that has a method like so: int do_something(string s, array|void extras) If they passed the method an array, then I would like to fill it in with some extra data for them. How do I do this, and make sure that it doesn't mess up the reference so they can actually access the data I put in the array for them? Thanks Adam

Re: Test failure report: 7.6.86/OSX-Intel

That's a standard bug in the GLUE module I thought was fixed. :-) It's not possible to do glGet until GL is initialized on most platforms.

Test failure report: 7.6.86/OSX-Intel
by H. William Welliver III 28 Jun '06

28 Jun '06

I was in the process of building some packages, and thought I'd run the testsuite. One test did fail, and I figured I'd send it on for completeness: /Users/hww3/Pike-v7.6.86/src/testsuite.in:10260: Test 10425 (shift 2) failed to return proper results. 1: 2: array a() 3: { 4: Stdio.File p = Stdio.File(); 5: object pid = Process.create_process(RUNPIKE_ARRAY + 6: ({ "/Users/hww3/Pike-v7.6.86/ src/test_resolve.pike" }), 7: ([ "stdout":p->pipe (Stdio.PROP_IPC) ])); 8: __signal_watchdog(); 9: string results = lower_case(p->read()); 10: __signal_watchdog(); 11: int err = pid->wait(); 12: int ok; 13: int failed; 14: if (((sscanf(results, "%*sok:%d", ok) != 2) + 15: (sscanf(results, "%*sfailed:%d", failed) != 2)) == 2) { 16: // No "ok", and no "failed". 17: return ({ err, results }); 18: } 19: return ({ ok, failed }); 20: } 21: o->a(): ({ /* 2 elements */ -1, "invalid memory access of location 00000ab0 eip=92c39c8d\n" })

bundles and solaris/x86
by H. William Welliver III 24 Jun '06

24 Jun '06

Are bundles broken in the latest 7.6 release? I wasn't able to build pike on a brand new installation without first installing nettle and gmp. The bundles seem to be present, and are untarred, but don't seem to be used. Everything worked fine after I built and installed them. Also, I packaged up the latest release for Solaris 10/intel. All of the usual features included from the standard install plus the companion software disc. I'm uploading it to: http://hww3.riverweb.com/dist/pike if someone wants to take them and put them on the main download site. Bill

I'm trying to compile pike7.7 Although after configure I get: SQLite.............. no (dependencies failed) Still during make process the process fails on sqllite. Shouldn't the makefile not be created if configure fails? Kind regards, marc

CMOD compilation
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 22 Jun '06

22 Jun '06

If I understand the code in precompile.pike correctly, all declarations, such as program placeholders and macros relating to the classes in a CMOD-file, should be placed at the location of the "DECLARATIONS" keyword. Is this correct? If this is the way it is supposed to work, it seems broken too me in 7.7 from CVS.
