| 05:40 | < McMartin> | Er |
| 05:40 | < McMartin> | Which languages have you used? |
| 05:41 | < McMartin> | The vast majority of languages either disallow this entirely or insist upon a special form for "strings with newlines in" or an escape code that means "newline inc" |
| 05:47 | < sshine> | Ling, Haskell, C, Standard ML. |
| 05:49 | < sshine> | Ling, if absolutely necessary I'd prefer the <<EOF ... EOF; syntax. |
| 05:49 | < McMartin> | C chokes on newlines in strings. |
| 05:49 | < McMartin> | It just also lets you concatenate strings at lex time. |
| 05:49 | < sshine> | yeah, that's pretty neat. |

| 13:38 | < TheWatcher> | ... does anyone know when php changed its class constructor naming from "class Foo { function Foo(...) { } }" to "class Foo { function __construct(...) { } }" ? |
| 13:44 | < Tamber> | Shortly after someone went "Oh, man, they'll get a kick out of this!" |
| 13:45 | < TheWatcher> | Yeah, well, I think 90% of the langauge came about that way. I just want to know whether using __construct will work on 5.1.3, and it seems the only way I can find that out is to actually /try it/, because they are dicks and don't actually provide documentation for old versions. |
| 13:47 | < Tamber> | Of course not, that would be useful. |
| 14:26 | | kw-sleep-n is now known as kwsn |
| 14:49 | < Ling> | TheWatcher: PHP 5 when all the massive OOP fixes came in |
| 14:49 | < Ling> | Also, it's documented in the Classes and Objects section |
| 14:51 | < Ling> | "For backwards compatibility, if PHP 5 cannot find a __construct() function for a given class, it will search for the old-style constructor function, by the name of the class. Effectively, it means that the only case that would have compatibility issues is if the class had a method named __construct() which was used for different semantics." |
| 14:51 | < Ling> | http://www.php.net/manual/en/language.oop5.decon.php |
| 14:52 | < Ling> | (They used to have a section for PHP4-style classes, looks like that's gone |
| 14:52 | < TheWatcher> | Oh, I've seen that. But it doesn't actually say which version of php5. And the php devs just fucking love to throw in ridiculous changes between minor versions, so it's not like you can even count on "php 5" meaning "all of php5" or "just some version, we can't be arsed to tell you which" |
| 14:54 | < Ling> | Aye, that's a change that came with PHP 5.0.0 though |
| 14:54 | < TheWatcher> | Fair enough. Thanks. |
| 14:54 | < Ling> | Sadly not on the changelog page for OOP :/ |
| 14:55 | < TheWatcher> | Mmhmm |
| 14:55 | < TheWatcher> | not like it's important enough to document, after all. |
| 14:56 | < Ling> | Really though, why are you using such an old version? |
| 14:56 | < TheWatcher> | Oh, I'm not - all my machines run 5.3.8 |
| 14:57 | < TheWatcher> | unfortunately, the IS people in work believe that CentOS is the moseawesomewonderfulgreat distro of all time |
| 14:57 | < Tamber> | "If it still compiles, it's not stable enough." |
| 14:58 | < TheWatcher> | The 'normal' install of php on CentOS is 5.1.3. I believe you /can/ make CentOS install 5.2, however the machine this needs to run on happens to be one of the ones I don't have root access on |
| 14:58 | < Ling> | D: |
| 14:58 | < TheWatcher> | (and I'd probably get lynched if I swapped in a new version anyway) |
| 15:00 | < Ling> | Anyways, here's some rage fuel: json_encode and json_decode were introduced sometime in PHP 5 before 5.3. json_decode can fail and will return false when it does. To get the error you need PHP 5.3 because that actually introduced the function needed to get an error code.. |

| 15:03 | < TheWatcher> | Sounds like mysqli::connect_error, which was broken until 5.2.9, unless you called it as mysql_connect_error() instead of $database -> connect_error. |
| 15:03 | < TheWatcher> | *mysqli_connect_error |
| 15:04 | < TheWatcher> | But anyway. Some commenting, and then I can hopefully return to more sane languages for a while |
| 15:05 | < Eri> | Stupid bot |
| 15:05 | < Eri> | It missed #math, which is definitely in the channel list |
| 15:06 | < Eri> | Wonder if it's in the oubliette |
| 15:08 | | * celticminstrel wonders if it could possibly be dangerous to accept regex input to be inserted into a larger regex expression. |
| 15:09 | < Tamber> | If you have to ask that, the answer is always "Yes" ;) |
| 15:10 | < celticminstrel> | <_< |
| 15:10 | | * Ling doesn't see how regex could be an attack vector |
| 15:10 | < Tamber> | Precisely! *cranks up the paranoia a notch or several* |
| 15:11 | < Tamber> | No, I don't know, either; but still... |
| 15:11 | < TheWatcher> | cm: which language, and rexexp flavour, might make a difference too. |
| 15:12 | < celticminstrel> | PHP, preg. |
| 15:13 | < Tamber> | Well, you could always run it through a regex to check it's not dangerous, right? *runs away before the brick lands* |
| 15:13 | < TheWatcher> | (if nothing else, an attacker can craft an expression that will make the regexp get stuck in a loop or something) |
| 15:14 | < celticminstrel> | Hm, stuck in a loop wouldn't be good. |

| 15:19 | < celticminstrel> | I kinda like the x[] = y syntax for append... |
| 15:22 | < RichardBarrell> | Ling: I thought that maybe Perl's regexes might have features where you can throw Perl expressions in inline. |
| 15:23 | < Ling> | Yeah, that'd be dangerous, but PCRE doesn't have that feature AFAIK |
| 15:23 | < RichardBarrell> | If you have a backtracking regular expression engine then someone can hand you a pattern like (a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?) and it'll blow up, or I think that ((.*)\1\1\1\1\1\1\1\1\1) can blow up. |
| 15:24 | < Ling> | RE:x[] = y, yeah, they actually deprecated array_push() at one point because of it being redundant. |
| 15:24 | < RichardBarrell> | By "blow up" I mean "hit the exponential worst-case" |
| 15:25 | < RichardBarrell> | If you want to let strangers hand you regexps then you have to use a real regular expression engine, i.e. one that doesn't implement backreferences in the pattern and lazily builds a DFA as it traverses the input text. |
| 15:25 | < RichardBarrell> | That or you set a timeout for evaluation. |

| 17:26 | < RichardBarrell> | celticminstrel: a timeout? I wouldn't expect preg_match to have that, and I wouldn't trust one in there anyway. |
| 17:28 | < RichardBarrell> | Doing timeout'd operations really reliably requires you to spawn a child process, then wait for that process (which you *can* give a timeout for) and murder the child process if it's still running. |
| 17:28 | < celticminstrel> | Ah. |
| 17:29 | < Attilla> | that sounds dirty |
| 17:29 | < RichardBarrell> | You run the possibly-an-infinite-loop in the child process. Also, you have the child process use setrlimit() (and I'm sure Windows has an equivalent) to restrict itself to a maximum possible CPU time expenditure too, just to be safe. |
| 17:30 | < RichardBarrell> | It's fine. fork() to your heart's content, just like Korn and your mother always intended you to. |
