php - Magento. Destination folder is not writable or does not exists -

-

hey i'm stuck following problem, plz help.

i "destination folder not writable.." when trying add image product, permission needed folders 777! had deleted files on server, didn`t touch db, reinstalled magento scratch new db, , ok. when switched previous db (change settings in local.xml) bug appeared again.

how can db impact folder permissions?

update:

thanx lot, found out magento jump method:

public function getbasemediaurl() {    return mage::getbaseurl('media') . 'catalog/product'; }

to following method:

public function getbasetmpmediaurl() {         return mage::getbaseurl('media') . 'tmp/catalog/product'; }

does know why , how????

there's 1 spot in magento code base uses error language.

file: lib/varien/file/uploader.php ... if( !is_writable($destinationfolder) ) {     throw new exception('destination folder not writable or not exists.'); }    ...

add temporary debugging code right above this

... if( !is_writable($destinationfolder) ) {     mage::log($destinationfolder);     //or     var_dump($destinationfolder);        throw new exception('destination folder not writable or not exists.'); }    ...

this let know exact folder magento wants write to, can't. examine folder, , you'll find it's not writable. reviewing edge cases on is_writable may shed light on subject.

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
