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.
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.
- 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.
- 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.
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.
adts.h: add Cache (landlord algorithm), move DynHashTbl here from
vfs_tree; expand RingBuf and fix its iterator
allocators: minor tweaks+bugfixes; add SingleAllocator C++ wrapper
config, types: avoid stupid ICC warnings
lib: add round_down, u32_from_u16, SAFE_FREE
This was SVN commit r3414.
