| 20:54.49 | Gaxme | Heya. |
| 20:55.07 | Gaxme | Random question of the moment: Do I need to free the result of a insert query? |
| 20:55.08 | Zanix|Work | hi |
| 20:55.16 | Zanix|Work | no, only select |
| 20:55.26 | Zanix|Work | otherwise you get a sql error |
| 20:55.40 | Zanix|Work | there are other instances where you hsould free it |
| 20:55.45 | Gaxme | That explains where those were coming from. =) |
| 20:55.46 | Zanix|Work | but I cant recall at the moment |
| 20:58.39 | PleegWat | try a var_dump of the result of an insert |
| 20:58.49 | PleegWat | It doesn't return mysql_result - just boolean |
| 20:59.10 | Gaxme | *nod |
| 20:59.22 | Gaxme | Something I'm doing is breaking the footer, I need to figure out what that is as well. |
| 21:00.34 | Gaxme | Unless... The footer is supposed to show up on the update page after sending data, correct? Nevermind, dumb question. |
| 21:00.40 | Gaxme | It shows sql queries and such usually. |
| 21:00.53 | Gaxme | I have somehow busted it. Heh. |
| 21:01.15 | PleegWat | Are you doing something fatal? Check your error log |
| 21:04.43 | Gaxme | Yep, memory exhaustion. |
| 21:04.45 | Gaxme | Bah. |
| 21:05.27 | Gaxme | The script itself is pulling 32meg. |
| 21:05.31 | Gaxme | I have my limit set to 50. |
| 21:05.45 | Gaxme | That's a lot of processing memory for a 3.1 meg lua file. |
| 21:05.56 | Gaxme | Of course, it's also processing everything it can. |
| 21:06.11 | Gaxme | I need to add in a flag for per-loot attendance and per-boss attendance. |
| 21:06.35 | PleegWat | There's a factor 5 expansion just from php array overhead |
| 21:07.31 | PleegWat | For memory usage, best chance is probably inserting stuff into DB right away then do the rest in sql |
| 21:09.14 | Gaxme | Hmm. I've never tried that. You mean actually taking all the data from the lua and dumping it to a temporary table first? |
| 21:09.21 | Gaxme | Then collating it out from there? |
| 21:09.40 | Gaxme | Hard for me to believe that SQL overhead is less than php. Heh. |
| 21:09.50 | PleegWat | sql overhead doesn't count to php memory |
| 21:09.57 | PleegWat | and sql's better at structured bulk data |
| 21:10.41 | Gaxme | Hmm. Can you point me in the direction of an example of that method? |
| 21:11.02 | PleegWat | not really. I do keys processing in DB, but that's something else entirely. |
| 21:11.07 | Gaxme | Right now it takes the LUA file and splits the parsing sections into separate functions. |
| 21:11.24 | Gaxme | Some of them are more intensive than others. |
| 21:11.48 | PleegWat | Are you cleaning up redundant php-side memory sufficiently? |
| 21:11.52 | Gaxme | Items, specifically, since it iterates through the items, then calls out per item to 1) record the item, 2) record the members who were there when it dropped |
| 21:12.05 | Gaxme | Probably not. |
| 21:12.22 | Gaxme | I don't think I'm a supercoder by any stretch of imagination. |
| 21:12.26 | PleegWat | Not writing to pass-by-value function parameter structs? |
| 21:13.29 | Gaxme | Hell, I completely forgot about that. |
| 21:17.03 | Gaxme | Let's see what that does. |
| 21:18.19 | PleegWat | If you're only using local temp variables for the full duration of a function, you should be fine. |
| 21:18.42 | PleegWat | But if you're stuffing in a lot of data, and you're not using it for the full duration of the function, or it's not local, unset it when you don't use it anymore. |
| 21:18.45 | PleegWat | Same goes for subarrays. |
| 21:19.27 | Gaxme | So things like foreach loops with variables should be unset at the end. |
| 21:19.57 | Gaxme | foreach( $array_values as $name ) { } make sure and unset($name); ? |
| 21:20.03 | PleegWat | yes |
| 21:20.21 | Gaxme | Can you set by reference also? |
| 21:20.33 | PleegWat | Or use foreach( $array_values as &$name ) {} |
| 21:20.40 | Gaxme | eg: I've got a global variable set at the top. |
| 21:21.07 | Gaxme | Can you do &$this->variable = value; ? |
| 21:21.17 | Gaxme | Or does that matter? |
| 21:24.17 | Gaxme | Fatal error: Cannot create references to elements of a temporary array expression |
| 21:24.17 | Gaxme | Boo! |
| 21:24.43 | Gaxme | That's using foreach( $array_values as &$name ) {} |
