From 414c70435dcd52eb67df59f56132837de0a63b64 Mon Sep 17 00:00:00 2001 From: Bastien Montagne Date: Mon, 23 Jun 2014 13:42:19 +0200 Subject: T39690: Modifications to Blender's 'temp dir' system. Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never automatically cleaned up, and can end being quite big when used by Blender, especially when we have to store per-process data (using getpid() in file names). To address this, this patch: * Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path), the other is a mkdtemp-generated sub-dir, specific to each Blender instance. * Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always reuse the same filename (quit.blend...) or generate small file (crash reports...). * Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option). * Erases temp sub-dir on quit or crash. To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows. Note that, as in current code, the 'recover render result' hack-feature that was possible with SaveBuffer option is still removed. A real renderresult cache feature will be added soon, though.
