adts: whip together inefficient LRU cache manager (mostly for comparing
vs. Landlord)
file_cache: fix self-test (now correctly deals with small cache sizes)
file_stats: more stats for file cache
trace, vfs: bugfix: ignore writes recorded by the trace
This was SVN commit r3684.
adts: slight improvements
allocators: change POOL_VARIABLE_ALLOCS to -1 for safety; fix invalid
assumptions of it being 0
lib: more expressive param names
file: add file_get_random_name for randomized trace generation; allow
file_cache.h to declare externally visible file_buf_alloc API
file_cache: zero-length file bugfix; also add several flags to the API
routines allowing statistics gathering to be disabled (avoids distorting
stats due to e.g. trace_entry_causes_io cache simulation)
file_stats: add archive builder info; separate IO timing and seek
accounting (-> correct results)
trace: add random generation capability
vfs: made responsible for cache hit/miss accounting (fixes cache miss
rate display)
This was SVN commit r3681.
file: change block size to 32kb (=> yields highest throughput)
archive, file_io: add additional block cache forwarding path when
reading uncompressed data from archive (avoids repetitive IOs)
file_io, file_stats: fix inaccurate and incorrect IO throughput
calculation
file_stats: refactor some calculations to avoid division by 0
This was SVN commit r3665.
vfs_mount: only notify archive builder of files that are archivable
vfs_optimizer: fix should-rebuild logic; make 2 criteria optional and
disable in final release for convenience
This was SVN commit r3651.
vfs: remove second call to tree_init (now done by vfs_mount)
vfs_tree: fix memory leak due to not destroying root node. commented and
armor-plated things while at it.
This was SVN commit r3647.
- lib, sysdep.h: move DIR_SEP to sysdep.h
- archive, compression: minor touchups
- zip: large refactor: all accesses to little-endian structs are now
done by helper functions (fixes bug: wasn't endian swapping ECDR). also
detect unfinished zip files (for VFS mount to ignore)
- tex_dds: fix comment
This was SVN commit r3634.
file_cache: add warning to cache_allocator to catch incorrect usage /
bugs
vfs_optimizer.cpp: tweak miniarchive threshold (currently have config
files in there; don't want those to trigger rebuild every time)
zip: clarification
tex_dds: we now bother checking the DDPIXELFORMAT mask bits because
uncompressed DDS files may be stored in any pixel component order, but
we require RGB for efficiency.
wsdl: fix failure to update; was constantly queuing events if mouse was
out of window
This was SVN commit r3627.
vfs: add VFS_MOUNT_ARCHIVABLE flag; allow archive builder to only
include files from mount points with this set.
VFSUtil: make EnumDirEnts more efficient while at it (uses PathPackage
and filename storage)
This was SVN commit r3618.
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.
- file_cache: add checker for allocations (catches bugs in debug mode);
fix bug that freed buffers even thought they were on extant list.
- vfs_mount: bugfix: was passing P_path to vfs_opt_notify when it should
be V_path
- vfs_optimizer: big refactor; fix bugs in TourBuilder causing some
files to be omitted from archive (thus forcing unnecessary archive
rebuild - because #files not in archive was too big)
This was SVN commit r3602.
- adts: Cache.remove_least_valuable was returning false prematurely even
though there were still some items pending eviction; that meant they
remained in cache
- file_cache: wasn't clearing exact_buf_oracle on reset. also made
make_read_only pass correct exact_buf rather than just rounding down.
This was SVN commit r3589.
- 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.
everything else: bugfix: buffers added to extant list via
file_buf_retrieve (i.e. moved from cache to extant list) didn't have
their long_lived flag carried over; this caused a "not freed
immediately" warning.
This was SVN commit r3580.
- 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.
- adts: add basic benchmark to self-test; use fminf instead of MIN; fix
overly pessimistic invalidation in Landlord_Cached
- allocators: no longer complain if DynArray is full
- lib: warn if rand() min=max
- archive: bugfixes: plug leak, correctly handle 0-length files, carry
over flags when reading uncompressed file from archive
- file: expose file_get_sorted_dirents and implement file_enum in terms
of that
- file_cache: many bugfixes (especially related to CacheAllocator
freelist)
- vfs_optimizer: finish implementation of archive builder
- zip: correctly handle 0-length files
- tex: add tex_is_known_extension
- sysdep: add efficient fminf implementation (assumes P6+)
- config: update archive builder call site
- gamesetup: add call for delayed self tests
- entity: return JSVAL_VOID as per philip's suggestion
This was SVN commit r3553.
fix crashdumps: was failing to write out to file (underlying cause:
current directory no longer being set)
app_hooks: add get_log_dir; used by debug and wdbg_sym
minor improvements/documentation in archive+compression+file_cache+zip
main: remove dead ScEd code
This was SVN commit r3498.
lib: add u32_hi/lo
archive: move archive builder logic here from vf_optimizer
file_cache: add flush() call - used when simulating cache
vfs_optimizer: WIP, not yet functional: file gatherer, 50% of TSP tour
generator
This was SVN commit r3486.
NOTE: wchar_t should be defined as a built-in type; no more need to
define manually or change project settings.
adts: disambiguate iterator type; add operator- as required by VC8
std::equal() implementation
precompiled: squelch stupid warning (that informs us that array members
are now actually default-initialized as called for by C++)
file_cache: remove debug variable
This was SVN commit r3464.
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.
byte_order: add FOURCC_BE and _LE versions (needed for zip)
ogl: quick hack: prevent crash on laptop by providing a
pglDrawRangeElementsEXT stub
file, h_mgr: update pool_alloc call site
tex: fix incorrect indexing/stride for mipmap generation
vfs_mount: disable archives (zip code is WIP)
zip: heavy WIP. add support for writing archives (needed for thesis);
revised Zip read code. sped up archive open. further major changes
pending.
wposix: moved allocator code (see above)
This was SVN commit r3298.
