# further documentation and improvements to lib/res/file code FILE_CACHE_BLOCK flag used more safely (copied in afile_read) add file_sector_size (set from sysdep code) documented and organized FileFlags moved publically visible file_buf* decls to file.h; add FileBufFlags file_buf_get: moved to file_io and renamed because it is not a part of the file_buf manager itself FILE_BLOCK_SIZE no longer exposed to users - it's an implementation detail. for alignment purposes, you should use file_sector_size (less wasteful) add page_aligned allocator (mmap) write buffers now allocated via file_buf_alloc(FB_FROM_HEAP) (avoids wasting cache space) append trace runs into the trace file (-> better input data for archive ordering) document lib_errors.h tex_load: add provision for file_flags, used by ogl_tex_load to prevent caching file data simulation, entitymanager: add perf measurements This was SVN commit r3725.

Cache: implement meat of landlord algorithm and add remove() allocators: add freelist capability to Bucket; add provision for variable XOR fixed size allocs archive: re-tag file buffers if reading uncompressed from archive; improve LFH fixup logic file_cache: add cache line invalidation; lock down pages (readonly) when IO finished file_io: cleanup+docs; properly cut off at EOF without breaking alignment. file_stats: add seek accounting (WIP) vfs_optimizer: also record file_buf_free in the trace. initial implementation of archive builder (WIP) zip: lfh_fixup now more efficient (does not involve buffer manager - instead it grabs LFH from temp blocks) tex: plug FileIOBuf leak. avoid writing to tex.hm because that is a read-only file_buf. This was SVN commit r3428.
