1) unify open/io interfaces: no longer distinguish between FileIo /
AFileIo. instead, one FileIo struct is always used; the
provider-specific data is embedded within it. this avoids the need for a
"base class", which is hard to access (f.fc.flags is ugly)
2) rename x_* redirector to xfile_* and move out of vfs_mount into
separate file
3) xfile is now implemented via "virtual functions" (avoids a lot of
boilerplate code)
4) xfile was too closely tied to vfs_mount (used internal fields);
fixed.
remaining lib/res files: made all flag parameters uint (not int) for
consistency
This was SVN commit r3776.
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.
trace: split code out of vfs_optimizer (was getting too large)
vfs_mount: expose API to unmount all (needed to be able to delete
archives after building)
vfs_optimizer: safely handle empty connection/node lists;
refactored+documented
vfs_tree: eliminate 'file in root dir' warning (can happen easily
enough)
rest: fixes/minor tweaks
This was SVN commit r3610.
- 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.
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.
- remove ScEd hacks and CFont et al macro rename
- fix accursed bug in VFS buffer management that was causing ReadFile to
fail without error (not allocating enough padding)
- vfs_tree: bugfix in tree_lookup
- waio: temporarily disable sector size determination (pending better
approach - need to determine if using DVD drive)
This was SVN commit r3421.
previous zip.* split up into archive, zip and compression. add O(1)
lookup via memento. add support for writing Zip archive. simplify IO by
having compression module allow queuing input buffers.
file: split up into file, file_Io, file_cache. add atom_fn that enables
string comparison via pointer compare. (stores all filenames/paths in
one place). add statistics gathering.
file_cache: landlord algorithm for caching files as well as LRU block
cache.
file_io: aio code that splits transfers into blocks revamped and made
into class.
vfs: filelist/trace code moved into new vfs_optimizer. add caching logic
to vfs_load.
vfs_optimizer: will generate zip archive (to replace current archive
builder script). not yet done
vfs_tree: major cleanup - now has nice base class rather than union
hackery.
This was SVN commit r3420.
