- allocators.cpp: fix: make sure all pool fields are reset in pool_free_all; correct matrix self-test - lib: fix self-test - lib_error: give "informational" return codes values > 100 (allows multiplexing with percent indicator) - archive: add clarification to afile_enum; use vfs_load when building archive (fixes caching problem); add support for progressive archive creation - file: allow pp_set_dir's path to end in slash (simplifies other code); add file_exists - file_cache: add stats+sanity checks to allocator; improve ExtantBufMgr find(); add ExactBufOracle to translate padded address returned by Cache to what was actually allocated; relax infinite-loop check; fix file_cache_reset - file_io: refactor callback logic so it can be used by vfs (needed for vfs_load) - vfs: vfs_load now supports calling back (required for archive builder) - vfs_mount: optimize path caching in afile_cb: due to atom_fn system, string compare can be done via pointer compare - vfs_optimizer: support auto-build of archive (progressive); improve should-build-archive check (WIP) - vfs_path: add util functions (also used in screenshot code) - vfs_tree: simplify pathname storage - wposix: mmap bugfix - main: call progressive archive builder; skip reload when doing so (documented) - JSInterface_VFS+scriptglue: add archiveBuilderCancel - ps/Util: use new vfs_path helper function for cleverer screenshot naming (correctly handles some being deleted) This was SVN commit r3578.
