6792e95517 # fix vtbl_magic compile error on VC8; fix incorrect type in u32_from_larger; explanation+cleanup
- move AllocatorChecker to allocators.h since usefulness is not limited
to CacheAllocator
- file: add note on casting File.opaque
- vfs_redirector: was missing u32 (fails on VC8)
- zip: fix u32_from_larger (was using incorrect type)

This was SVN commit r3786.

44901d38b9 # further documentation and improvements to lib/res/file code
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.

d6abc57868 # add instrumentation to file_cache; bugfixes
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.

8371f42da9 # IO bugfixes and improvements; more support for cache/seek measurements
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.

6eda8c2209 file_cache: make infinite loop warning less likely
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.
2006-03-16 18:57:09 +00:00
1d5308316e bugfixes for problems reported by philip: (thanks!)
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.
2006-03-14 07:20:12 +00:00
e0280949fd file_cache: fix: add buf/size combo to exact_buf_oracle if file_io rounded size up.
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.
2006-03-07 05:44:34 +00:00
16fe4eeda2 - adts: add TODO comments
- 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.
2006-03-04 18:58:09 +00:00
ca1ac3034e fix 2 gnarly bugs:
- 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.
2006-03-03 20:49:19 +00:00
dda6268466 - cgui: now convert EventName to lowercase in SendEventToAll
- 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.
2006-03-03 06:03:16 +00:00
39a9eb19cf again raised "infinite loop" warning threshold because it was still being hit, apparently. value is still plausible.
This was SVN commit r3582.
2006-03-02 07:23:30 +00:00
04b72b29b4 archive: new rule for choosing whether to compress files or not: leans heavily toward the former because that uses less memory when loading (less loss due to internal fragmentation)
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.
2006-03-02 02:21:55 +00:00
0fd85b76db automatic archive builder now functional and enabled.
- 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.

4a0baf529d rename free() to dealloc() to avoid need for #include "nommgr.h"
This was SVN commit r3557.
2006-02-23 18:58:16 +00:00
bc07b9ff0a file code v2 is now feature complete and works.
- 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.
2006-02-23 07:55:32 +00:00
0a368a4fec massive update to adts: cache now implemented via templated policy classes.
Entity.h: fix minor warning

This was SVN commit r3539.
2006-02-19 18:51:00 +00:00
5081b38c43 debug: remove old prototype
file_cache: use new remove_least_valuable interface
zip: add dox

This was SVN commit r3514.
2006-02-15 03:03:17 +00:00
c4e3037e60 adts: add LL_OPT_* defines that enable optimizations (some only make sense if there are tons of files, and need to be able to disable them for thesis). realized this would be perfect application of policy template classes, which will replace this.
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.
2006-02-11 22:49:09 +00:00
21f8f8555e adts: remove_least_valuable safely handles empty cache
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.
2006-02-09 05:59:33 +00:00
920795fd85 file_cache: add refcounting to ExtantBufMgr (required for correctness)
This was SVN commit r3473.
2006-02-04 23:32:01 +00:00
2f438a6889 cache_allocator bugfix: do not attempt to coalesce allocations that are at start/end of committed region. fixes self-test failure.
This was SVN commit r3466.
2006-02-03 21:44:09 +00:00
987a6b7d4e fixed wchar_t issues; now correctly separates utf16, CStrW and jschar.
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.
2006-02-03 20:36:15 +00:00
1227cb2f6d adts: add RingBuf self-test. RingBuf: make entry#0 the 'head' and pop_front a no-op if empty.
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.
2006-02-03 04:02:53 +00:00
7862e79e84 adts: optimize landlord algorithm at advisor's request (only relevant if we have tons of files in cache)
trace: make note of IO size

xmlutils: fix old remnant of Handle vfs_load return type.

This was SVN commit r3456.
2006-02-02 04:11:07 +00:00
d11fcc8257 file_cache: bugfix in CacheAllocator
hook up file_stats; implemented stats_dump (gives somewhat detailed
report at exit)

This was SVN commit r3448.
2006-01-31 07:48:32 +00:00
06412a7751 allocators: bugfix (wasn't setting freelist to 0)
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.
2006-01-31 03:47:52 +00:00
ecbcc59fba bugfix: no longer make freed buffers readonly because we need to write boundary tags into them for coalescing
This was SVN commit r3432.
2006-01-28 23:02:26 +00:00
cda1e4c177 bitten by free() redirector macro again.. fixed
This was SVN commit r3430.
2006-01-28 22:30:28 +00:00
e07622b56a Cache: implement meat of landlord algorithm and add remove()
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.
2006-01-28 22:19:42 +00:00
3b4295a177 Linux build fixes
This was SVN commit r3427.
2006-01-28 22:04:09 +00:00
4a508c6b87 all lib/res/file headers included in file_internal.h
split stats into separate file; different call mechanism; add lots of
stats (WIP)

This was SVN commit r3424.
2006-01-25 07:21:45 +00:00
7838627cd2 - vfs_load now returns error code and takes FileIOBuf; that must be freed via file_buf_free. if Handle is needed, use mem_wrap.
- 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.
2006-01-24 08:16:29 +00:00
36cbf23c8e v2 of file/res code for thesis:
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.
