674bbc3735 # archive builder now unmounts and deletes old archives after building a new one
vfs_optimizer: also refactor existing_archives. all existing root dir
entries are filtered and only archives remain.

6eac18d9fe # housekeeping (improve unreachable code annotations and avoid compiler warnings)
adts: use SAFE_FREE
config: add CONFIG_FINAL; use it in
compression,vfs_optimizer,scriptablecomplex
lib: add discussion of unreachable code avoidance; revise UNREACHABLE
and add NODEFAULT
ogl_tex, tex_dds: remove some unnecessary UNREACHABLE
sysdep: move compiler-specific implementation of UNREACHABLE here.
use NODEFAULT in snd, wdbg, wposix, wsdl

This was SVN commit r3739.

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.

b5ad9faf74 # fix STL complaint when running on VC8 and building archive
(STL implementation AFAICS incorrectly disallows taking &vector[0] if
empty but memory has been reserved)

This was SVN commit r3715.

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.

b605cc8a85 adts: fix brain-dead bug that was slowing down Divider_Recip
vfs_optimizer: add note on future improvements

This was SVN commit r3622.
2006-03-10 22:35:58 +00:00
201aae41d9 file: pp_set_dir fix: safely handle case where pp.path already contains data; add TFile* member to DirEnt
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.
2006-03-09 21:37:23 +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.

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
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.

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.

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.

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.

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.
