| 12:34 | <@TheWatcher> | Anyone know why, in php, $files = glob('/foo/bar/womble/*.php') would refuse to give back any files despite having read permission on the directory and files in question. Other than php being shit? |
| 12:42 | <@simontwo> | does it have read permissions recursively towards /? |
| 12:44 | <@TheWatcher> | yep |
| 12:45 | <@TheWatcher> | And I can open the direcotry with diropen() |
| 12:46 | <@TheWatcher> | sorry, opendir() |
| 12:47 | | * TheWatcher pokes around, finds that glob() doesn't appear to be returning any files from /anywhere/ |

| 19:19 | | * Vornicus outsourced his "swap radio buttons" code, learns a lot more about javascript-html communication. |
| 19:34 | <@gnolam> | And the collision response completely blows up. Yeah, I think I'll try getting back to this when I'm feeling better... |

| 20:48 | | * TheWatcher vaguely pokes the channel now that there are more people awake |
| 20:48 | <@McMartin> | What's up? |
| 20:49 | <@TheWatcher> | Anyknow know why php's glob() might return zero files, when the equivalent code implemented using opendir()/readdir()/fnmatch()/closedir() run on the exact same directory might work perfectly? |
| 20:50 | <@Derakon> | You checked the PHP docs for the function? |
| 20:50 | <@TheWatcher> | Yep, it's typically useful. |
| 20:50 | <@Derakon> | Okay, that's about all the advice I can provide then. :\ |
| 20:51 | <@TheWatcher> | I also spent a good part of the morning crafting ever more cunning google queries, to no avail. |
| 20:51 | <@McMartin> | I've successfully avoided learning anything about php. |
| 20:52 | <@TheWatcher> | I even looked at the php sourcecode, and couldn't find anything helpful there... at this rate I suspect I may need to stick some fprintf()s in the php source, compile it, and try again to track it down |
| 20:52 | <@Derakon> | Anything in the PHP docco comments, maybe? |
| 20:53 | <@gnolam> | Humm. Is there any C++ implementation nowadays where std::list::size() isn't O(1)? |
| 20:54 | <@TheWatcher> | Dera: couldn't locate anything; the majority of comments seemed to be people coming up with 101 different ways to do recursive globs |
| 20:54 | <@Derakon> | Heh. |
| 20:55 | | * TheWatcher shrugs, will just do it the hard way tomorrow, after meetings |
| 20:55 | | * TheWatcher goes back to perl ¬¬ |
| 20:56 | <@jerith> | gnolam: Aren't things like that part of the spec? |
| 20:57 | <@gnolam> | IIRC, it's only a recommendation. |
| 20:57 | <@gnolam> | (And that pretty much sums up C++!) |
| 20:58 | <@TheWatcher> | Pretty much damn near any language, ime |
| 21:03 | <@McMartin> | STL has performance guarantees in the spec, IIRC. |
| 21:03 | <@McMartin> | Checking now to see. |
| 21:04 | <@McMartin> | size() is permitted to be O(n) |
| 21:04 | <@McMartin> | empty(), however, is guaranteed to always be constant time. |
| 21:08 | <@Derakon> | ...I'd hope so for empty(). |
| 21:08 | <@Derakon> | return head != null; |
| 21:08 | <@gnolam> | In this case, I need size(), not empty(). |
| 21:09 | <@gnolam> | But I found documentation that MSVS's size() is O(1) at least, and that's good enough. |
| 21:12 | <@McMartin> | Derakon: What this means is that STL implementers are not allowed to define empty() as "size() == 0" |
| 21:13 | <@Derakon> | If they do, nobody'll use their implementation anyway. ¬.¬ |
| 21:14 | <@McMartin> | (I pulled this actually from an STL programmer's guide, which reminds you to use empty() in your own code instead of comparing size() values.) |
