#50373 [Bgs]: imagepng doesn't doesn't have lockflags

ID: 50373 User updated by: rugkiks at gmail dot com Reported By: rugkiks at gmail dot com Status: Bogus Bug Type: GD related Operating System: GNU/Linux PHP Version: 5.3.1 New Comment: It's the blocking feature i'm after. When the image is updating, other fopen's needs to get blocked. It makes my code much more simpler. Also, you can do this with ImageMagick, since it allows you to supply the file handle yourself http://php.net/imagick_writeimagefile The only reason why i'm requesting this feature to GD, is because of GD's speed. rasmus: The renaming-method is nice. But in my case, i need the users to be blocked until the image is ready. Not just show the old one, or return a 404. I can program my way out of it, but it's messy. I guess i'm saying that it would be nice with a http://php.net/imagick_writeimagefile for GD. Thank you for the response.

Please follow Rasmus' advice here, best possible solution. ------------------------------------------------------------------------ [2009-12-03 16:39:32] rasmus@php.net I'm curious why you want this. Locking is almost never the right solution for a web app. Writing to a temp file and then atomically rename it into its final destination. Adding locks to every library function PHP can call that can potentially write files is not feasible. ------------------------------------------------------------------------ [2009-12-03 12:31:19] rugkiks at gmail dot com Description: ------------ http://php.net/imagepng Apparently there is not way to lock files while writing to them. I'd like to see a similar behavior like the flags in http://php.net/file_put_contents Maybe the file actually get's locked. I can't test it.
