- error codes now accessed as ERR::NO_MEM, INFO::OK etc.
- no more X-macros => the above are now recognized by visual assist
- error codes are defined by the module originating them (lib_errors has
some generic ones)
=> no full rebuild when adding some
- error descriptions are now in C++ files => can be changed without full
rebuild
added AT_STARTUP in lib.h.
This was SVN commit r4374.
file_cache: avoid caching 0-length files (prevents div by 0)
adts: bit more defensiveness against size=0
trace: now use "dividers" in the trace file instead of relying on
monotony property of the get_time source. this avoids incorrectly
splitting the trace into runs when time is actually not monotonous
(which would cause lots of warnings), e.g. due to debugger.
in the process, changed interface to return (most-recent first) runs,
instead of only the raw unsorted entries.
This was SVN commit r3832.
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.
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.
