So, how about that switch to Subversion, eh? I'd very much like to rename lib/modules/_Image.pmod to Image.pmod and src/modules/Image to _Image, to get rid of image_magic_index, and with svn I could do that without messing everyones working copy up...

further debugging of pike/windows
by H. William Welliver III 19 Jul '06

19 Jul '06

Ok, I got a little bit further. I'm able to get it to spit out at least some more information: Z:\Users\hww3\Pike-v7.6.86\build\windows_xp-5.1.2600-i686>pike -t10 - DNOT_INSTALLED -DPRECOMPILED_SEARCH_MORE -m "c:\Program Files\pike\lib \master.pike" - -: program(Users\hww3\Pike-v7.6.86\src\modules \files\udp.c:986)() - -: returns: object(Users\hww3\Pike-v7.6.86\src \modules\files\udp.c:986) - -: program(Users\hww3\Pike-v7.6.86\src\modules \files\udp.c:1010)() - -: returns: object(Users\hww3\Pike-v7.6.86\src \modules\files\udp.c:1010) - -: 15483d4->__INIT() \Users\hww3\Pike-v7.6.86\src\port.c:699: Fatal error: Buffer overflow in VSPRINTF. Got exception when trying to describe backtrace. Turns out, the problem is that on my build machine (OSX/Tiger Intel), sed doesn't like the magic cookie used in master.pike.in, complaining about illegal byte sequences. As a result, master.pike was an empty file, causing Pike.exe to bail out. Any chance we can trap that problem (perhaps printing an error to that effect) rather than segfaulting? I've run verify, and it fails 2 tests: /Users/hww3/Pike-v7.6.86/src/testsuite.in:9212: Test 6889 (shift 2) (CRNL) failed. 1: mixed a() { foreach (({1075550400,94691300,220921700,347152100,473382500, 2: ^I^I 599612900,725843300,852073700,978304100,1104534500, 3: ^I^I 1230764900,1356995300,1483225700,1609456100,1735686500, 4: ^I^I 1861916900,1988147300,2114377700 5: ^I^I }),int t) if(mktime(gmtime(t))!=t) return t; return 0;; } 6: mixed b() { return 0; } 7: Error: Time conversion failed.

by Bill Welliver 14 Jul '06

14 Jul '06

anyone have a pre-compiled version of nettle (or a know working copy of gmp) for windows? I managed to get the remote compilation process working, but neither of the bundles want to compile properly. Bill

Then I understand. It fits your concept of pragmatism, while not mine nor Peter's, and it ticks off Martin Bähr's ideas of freedom. :-) All that said, and without myself having dived into technicalities in a FishEye installation, I'm sure people would use the system if you brought it online somewhere and it wasn't required to run off the not-quite-state-of-the-art pike site. (Subversion has good APIs that make most things nonnecessary to run on the repository machine, so I'm assuming it at least possible. Though if it were, we would probably not have this thread in the first place.) The reasoning to use any tool short of perfection is that it scratches some itch better than not using a tool at all, and those imperfections are addressable with sa[nf]e licenses. Trac would have been great and already set up here, had it been comfy in a solaris locale or had we had operations linux based. FishEye may be neat if somebody sets it up somewhere and it just solves issues as well. We're no worse meritocracy than any other hacking camp, so "not invented here" never matters to "not maintained here" software. What qualifies as comfy rarely changes with arguments, though, so trying to convince any voice in the thread to embrace FishEye is probably moot.

There was a test installation but no decision was made to use it one way or the other. It was apparent at the time that noone had the time or interest to see if we could really use it.

And I have been involved in enough product evaluations to know that most packages are crap in one way or the other and deserved to be disqualified. You just have to decide what areas you don't want it to stink at and find the one that looks like the least amount of pain.

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
