Simple file-per-block saving WIP. Compiles but didn't test. 2019-05-28 00:40:09 +01:00			`#ifndef VOXEL_STREAM_FILE_H`

Added LZ4 compression to saved blocks. Makes them fit in single sectors much more often, increasing performance 2019-08-17 18:15:16 +01:00			`#include "voxel_block_serializer.h"`

Added first working version of region save format, still WIP 2019-08-14 20:34:06 +01:00			`class FileAccess;`

Refactor generators and streams - VoxelGenerator no longer inherit VoxelStream - VoxelStream is now more focused on files - Nodes have separate stream and generator properties - Generators use 2 dedicated threads instead of sharing a single one with streams - TODO Image.lock() is problematic for multithreading - TODO Voxel graph can cause RWLock contention if edited while it runs - TODO Saving generator output no longer works, need to put it back 2021-01-17 17:18:05 +00:00			`// TODO Might be removed in the future, it doesn't add much.`

Added stat for time spent opening files 2019-08-18 16:10:40 +01:00			`FileAccess open_file(const String &fpath, int mode_flags, Error err);`
Made file streams thread-safe (but still won't be used in more than one thread) - Added a global file locker so threads can synchronize when accessing files - Added mutexes to serialize access to file streams (i.e to call in series) - VoxelStream API now expects implementations to be thread-safe - Did some logic/data separation in RegionFile in case we need an in-memory implementation, however I might just use SQLite in the future instead 2021-01-16 13:34:45 +00:00
