- compression: now use "fastest" compression mode and more memory unless
in FINAL build. this greatly speeds up archive generation at expense of
1.5% size increase (fine during development). done because profiling
shows ZLib accounts for 78% of CPU; practically nothing else shows up,
which shows effectiveness of compressing in parallel with reading from
disk.
- file_cache: documented; fixed several potential issues with exact_buf
when invalidating files.
This was SVN commit r3586.
- 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: allow pool_create at NLSO ctor time
lib: add rand() function based on libc rand and self-test. (this allows
easily returning a random number within a range, and avoids a number of
pitfalls - the naive rand()%range approach is baaad)
precompiled: add self_test.h, so that self tests won't be accidentally
disabled by forgetting to include the header
file_cache: add self-test; fixed 2 bugs that exposed (was incorrectly
splitting large blocks and not setting class_size bit properly). fix
weird corner case in BlockMgr (attempting to free LRU block but it is
locked).
file_io, wdbg_sym: tiny fixes
This was SVN commit r3461.
archive: afile_read bugfix (wasn't returning byte count)
byte_order: add to_leXX, implement read_leXX in terms of that, add
write_leXX (and also big-endian versions)
compression: support 0 length buffers + minor fixes
file: no longer support passing fn_len (that didn't work anyway due to
DynHashTbl find(const char*) interface); add FILE_DONT_SET_FN
optimization that prevents cluttering name cache.
file_cache: add logic to verify load/free/load/free sequence; add
FILE_LONG_LIVED flag to specify exceptions (e.g. XMB files that don't
free their buffer immediately)
vfs_mount/vfs_tree: bugfix (was mixing up portable and VFS paths)
vfs_optimizer: small fixes; creating Zip files now works
vfs_tree: add PathName that stores pointer to path and name component
for efficiency + convenience
zip: bugfixes (wasn't endian safe; incorrect handling of cmethod; forgot
to initialize ZipArchive members)
config: add -buildarchive flag
Xeromyces.cpp, FileUnpacker.cpp: add FILE_LONG_LIVED
mapreader: bump time estimate for ReadXML
This was SVN commit r3446.
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.
- made file_io_wait buffer non-const (less const_casting around -
buffers are really non-const. besides which, inadvertent use will be
caught via MMU)
- zip: disambiguate abs() param
This was SVN commit r3426.
- 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.
