CIDR parsing code ?
by Xavier Beaudouin 01 Oct '03

01 Oct '03

Hello there, I am looking forward a CIDR parsing code to check if an accessing IP is belonging to a specific CIDR. Idealy I'd like something like this : > IP_check("192.168.2.0/24")->check("192.168.1.1"); This will return 0 if its doesn't belong to the specified CIDR or 1 it is ok ... Any clues ? /Xavier

readline bug?
by Martin Baehr 30 Sep '03

30 Sep '03

look at the attached script, it messes up the terminal. remove a few questions, and things are fine. (if it seems fine now, try adding a few questions) of course i realize that reinitializing readline is not a good idea (fixing that fixed the bug) but i still wonder if the behaviour is a bug anyways. greetings, martin.

zero_type();
by Peter Lundqvist (disjunkt) ＠ Pike (-) developers forum 29 Sep '03

29 Sep '03

I've been doing some calculations on genome mutations and I've been finding myself doing a lot of if(zero_type(foo) && zero_type(bar) ... && zero_type(gonk)) ... when checking up on user input that is used to index mappings. So... I was wondering if it is safe to do this? Or perhaps - even make zero_type() do this by default? int zero_types(mixed ... tt) { if(arrayp(tt)) { foreach(tt, mixed t) if(zero_type(t)) return 1; return 0; } return zero_type(tt); } It seems to work alright - but I feel that this might perhaps in some way, I havent thought of, dangerous. > mapping m=(["A":1]); > zero_types(m["A"]); (9) Result: 0 > zero_types(m["R"]); (10) Result: 1 > zero_types(m["R"],m["A"]); (11) Result: 1 > zero_types(m["A"],m["A"]); (12) Result: 0 > zero_types(m["A"],m["R"]); (13) Result: 1 > zero_types(m["R"],m["R"]); (14) Result: 1

bug: casts to string for long double and long long int are incorrect (7.4.28 rel)
by Alexander Demenshin 27 Sep '03

27 Sep '03

Hi, Still experimenting with long* types, found one problem (so far): --- opcodes.c:367 --- case T_INT: sprintf(buf, "%ld", (long)sp[-1].u.integer); break; case T_FLOAT: sprintf(buf, "%f", (double)sp[-1].u.float_number); break; --- snip --- As you can see, it won't work correctly in case when long long ints or long doubles are in use. Testsuite is also a bit unprepared for this case (several errors, most of them due to this bug). Regards, /Al

utf8_char_index

The main reason to make these functions go fast is actually to prevent people from using UTF8 internally and the PCRE regexp in UTF8 mode themselves... :)

configinfo.txt

Have I a temporary blindness, or did configinfo.txt disappear from the xenofarm files? (Benchmark is nice, though.)

Nilsson, did you have any good way of inserting Regexp.PCRE? I want to write the glue in lib/modules, but I'm getting fuzzed by the compilation orders (again). Is it supposed to work like this? 1) I moved Regexp (the c+pike glue) to Regexp.Builtin, using MODULE_INIT() location setting 2) I make Regexp.pmod/module.pmod inherit Regexp.Builtin, and then this happens: | > Regexp("["); | Cannot call undefined lfun `(). | > indices(Regexp); | (1) Result: ({ /* 11 elements */ | "`()", ...and the rest that should be there... | "Builtin", | "module", | "___Builtin", | }) | > Regexp["`()"]("hej"); | (2) Result: Regexp.SimpleRegexp(hej) There's nothing magical about the old Regexp module, | SimpleRegexp `()(void|string regexp) { return SimpleRegexp(regexp); } so what's going on? Why does `[] work but not `->?

utf8_char_index
by Mirar ＠ Pike developers forum 24 Sep '03

I can also add my code as a long, big ugly class in Regexp's module.pmod.in, but that also feels wrong. Bah, I'll just add my code to _Regexp_PCRE's module.pmod.in as Nilsson suggested and insert it in Regexp's module.pmod.in.
