<0> chroot apache this night
<1> Tonight, tonight.
<1> Save tonight, fight the break of dawn!
<2> jpeg: they wont be able to run any of it; like i already said, i can control resource usage. that includes control over processes.
<3> or you can just go to #postgresql. There's a bunch of dorks there discussing magic incantations that prevent exploits
<3> like the one guy chmods wget and perl 700, therefore he is immune to attacks
<4> ew73: Eagle Eye Cherry. What a bizarre name. That's actually his name.
<2> oh, hey; here's an idea
<1> perl's power is greatest at the full moon. You must go, skyclad, into the field, and dance the dance of -T, and you will see the error of your ways.
<2> can a perl script change the uid/gid of the current apache child?
<5> that ****in retarded.
<2> i mean, a mod_perl script
<1> hobbs: The 90s were a strange, strange time.
<5> for hours of fun and entertainment, go to larp.org
<6> rutski89: only if it is running as root
<2> pravus: that's doable.
<2> that's my solution then! :D
<7> ok what did larp.org do?
<7> it's a completely empty page
<5> hmm
<5> well, it used to be a place for people who are into Live Action Role Playing.
<4> ew73: I heard that song in the 90s, forgot about it, and then I downloaded this video game remix tune from the internet, and something bugged me about it
<5> I guess they finally got kicked out of their parents basement
<7> irc is enough live action role playing for me
<5> the pictures were the best part
<5> and sometimes you get video!
<4> ew73: and then I realized that there was this section that (intentionally or not) perfectly paralleled the chords to Save Tonight
<2> Have each apache child serve only one request, then die. at the beginning of serving the request a mod_perl hook changes the uid/gid to match the vhost that was requested. hence any mod_perl stuff that's executed later will subject to the restrictions put upon that user; and one of those restrictions can be the lack of access to system files! :)
<4> ew73: except for about a week it was just "that song, dum de dum dum de, um, da da dum, dum de dum dum dum"
<1> hobbs: Dork. :)
<4> ew73: and then all of a sudden it popped into my head ;)
<8> Eagle Eye Cherry is related to Neneh Cherry who sang "Buffalo Stance"
<8> just fyi
<8> ;)
<5> Lets say I download lots of web pages with LWP. Can someone tell me a good way to download all these files into one compressed file without first downloading each page into a directory first?
<9> jrsims: A) why? B) most compressors can easily add in memory files to an archive
<5> ..oh, I need to be able to extract files as needed from that compressed file.
<9> um, so?
<5> buu: I have a project where I need to update my web archive frequently with new pages, and I want that archive to be immediately portable.
<9> So put them in a zip file.
<5> but I need perl to read/write from that file almost like I would a directory. Is that possible?
<1> eval: 3.59*12
<0> ew73: 43.08
<9> buubot: restart
<9> fifty window messages later
<5> basically, I'd like to read/write to an archive file on the fly and use the fastest possible compression/uncompression method.
<5> and I don't know benchmarks.
<9> So um, do it
<5> so I'm looking for advice
<5> ****.
<9> buubot: die
<10> uncompressed is the fastest compression/uncompression method.
<9> hrm
<11> Botje: not sure if you're still here, but thanks for the info regarding closures. I learned something new. And it was exactly what I needed.
<9> eval: 32
<4> freeone3000: the ratio ****s though ;)
<0> buu: 32
<9> HE LIVES
<10> Er. Is .tar.b'ing it on copy an option?
<10> *.tar.bz2ing.
<9> freeone3000: Not really.
<12> hi buu
<9> NOZKOZF
<13> i use recursion for matching nested parentheses: "$re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;" now i need to use recursion the other way around, that is, any character BUT parenthesis should act as a parenthesis
<13> for instance, i want to replace "use only recursion" with "u(s(e( (o(n(l(y( ()r)e)c)u)r)s)i)o)n". to keep it simpler, the source text includes *no* parentheses.
<9> I'm sorry
<14> ok i need to create a code that cycles through a file, and checks an argument to see if it compares to a line in the file, and returns true if it does ... how to do that?
<15> use grep?
<16> grep 'foo' file
<16> yeah, stuuf knows the score!
<14> from within perl?
<17> `grep 'foo' file` ;)
<15> `grep foo file
<15> `
<17> i win!
<14> oo... ok.. i am more of a php guy... but i have to manage this perl site... movable type actually
<14> thanks guys
<15> open <IN>, $file; grep {/foo/} <IN>;
<14> whts <IN> again?
<15> a filehandle
<15> open IN, $file; grep {/foo/} <IN>;
<15> first one shouldn't have <>
<15> <IN> reads a line (or all lines) from a file
<14> ok i have to read up how perl opens/closes files before i ask anymore dumb questions
<15> perldoc perlopentut
<0> Type 'perldoc perlopentut' in your shell or go to http://perldoc.perl.org/perlopentut.html
<17> open IN, "filename"; return grep {/foo/} <IN> ? 1 : 0;
<17> wow that was a pointless use of return ... ? 1 : 0
<15> not totally pointless
<14> hmm hang on let me put together something really quick and see if i can get this to work
<15> say you want your caller to know if something was true but not how true it was
<15> in this case it doesn't matter, but it could somewhere
<18> 0 | !!grep /foo/, <IN>
<14> open INFO, "< datafile" or die "can't open datafile: $!";
<14> ok this opens "datafile" and ***igns it INFO handle
<14> right?
<15> it's better to do open INFO, '<', $datafile
<14> < for input i am ***uming?
<15> yes, just like in a shell
<14> 0 | !!grep /foo/, <IN>
<14> wht is that?
<4> haha
<14> thts why i think perl is hard for php guys atleast.. i asked a ques and i get 10 ways to do the same thing
<15> exactly!
<4> kunjan: why is that bad? :)
<14> because it confuses me.!
<14> lol
<15> there are thinngs that perl can do 10 different ways but that php can't do at all
<14> yeah i agree
<14> open BANLIST,'<', 'ban.list' or die "can't open datafile: $!";
<14> ok now i need to grep this
<15> grep /foo/ <BANLIST>
<14> for an arg say $arg
<14> ok
<14> can i write grep /$name/ <BANLIST>
<15> that reads all remaining lines from the file and p***es them to grep
<14> ?
<18> grep /foo/, <BANLIST>
<15> yes
<18> comma needed
<14> oo ok
<15> comma if you're doing a regex, but not if you use a sub, right?
<14> sub as in function right?
<18> grep //, or grep { // }
<15> yeah, you can do stuff other than just regexps
<14> lets avoid regexp for now please?
<14> lol
<18> grep $_ eq $foo, @list also works
<14> i need to compare entire line to $name
<14> one entry per line
<17> what tybalt89 just said is what you need
<15> eq is the string equality operator
<15> never make the mistake of comparing strings with ==
<18> remember the \n
<14> 0 | !!grep /foo/, <IN> ok this.. it returns 1 if <in> has it? 0 otherwise?
<15> couldn't you chomp them?
<13> i use recursion for matching nested parentheses: "$re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;" now i need to use recursion the other way around, that is, any character BUT parenthesis should act as a parenthesis; for instance, i want to replace "use only recursion" with "u(s(e( (o(n(l(y( ()r)e)c)u)r)s)i)o)n". to keep it simpler, the source text includes *no* parentheses.
<14> open BANLIST,'<', 'ban.list' or die "can't open datafile: $!";
<14> print 0 | !!grep /'lala'/, <BANLIST>;
<14> that returns 0 all the time
<15> get rid of the 0 | !!
<14> aww ok
<14> wht do the !! do?
<15> i think that was put there to confuse you ;)
<15> not not?
<14> why twice?
<18> print 0 | !!grep /lala/, <BANLIST>; # I doubt the 's
<14> i removed the 0 | now it doesnt do anything
<15> m'lala' if you really like the ' character
<14> open BANLIST,'<', 'ban.list' or die "can't open datafile: $!";
