The web-ifc entry is re-measured with teardown outside the clock, a warmed seqins, two hash controls and a vector indexed by express ID
a705a00Oct 4
Martin Leitner-Ankerl
web-ifc's IFC loader on its public models: 5.1.0 is level with 4.8.1 or up to 6% faster, and std::unordered_map parses 1.1-1.3x faster than either because the express IDs are sequential

release: 5.3.1

Martin Leitner-Ankerl
The every-read test runs on a table whose value container is the caller's own, too
633ab7eOct 4
Martin Leitner-Ankerl
cbegin() and cend() call the table's own const begin() and end(), so they work on any view, and a test calls every read on one

Fix visit on read-only map and set views

release: 5.3.0
0d34cfeOct 3
Martin Leitner-Ankerl
Remove the session handoffs and the Copilot instructions, and correct what the docs said that is no longer true

Reflection on the 2026-10-03 issue pass: two CLAUDE.md rules, one skill line, and probe_length.cpp's lookups spread over every key
d84d7e8Oct 3
Martin Leitner-Ankerl
A preferred lane checked before the group compare loses 1.3-1.8x on scrambled integer hits for 9-15% on dense ids
8d8ffffOct 3
Martin Leitner-Ankerl
The 10 instructions per hit against indivi::flat_wmap are clang's, and the 10 cycles are the value index on both compilers
975fd15Oct 3
Martin Leitner-Ankerl
scripts/ab: probe_length.sh takes any patch stack (PROBE_PATCHES) and counts only hooks it can find, samples intervals only between checkpoints; label fixes after review
6b0608dOct 3
Martin Leitner-Ankerl
Four ways to take back a churned table's drift or skip its second hash, measured and rejected

mapped_view: cleanups after review, and the round trip's unmapped check only where /proc/self/maps exists
358ec91Oct 2
Martin Leitner-Ankerl
test/unit/mapped_view.cpp: mv_remove_on_exit gets a constructor; from C++20 a class with declared constructors is not an aggregate
acadc27Oct 2
Martin Leitner-Ankerl
mapped_view: measured on hugetlbfs itself, 1.02-1.16x the 4 KB file's lookups from 4M to 64M entries, a 4 ms start and one copy for every process
ebb83f3Oct 2
Martin Leitner-Ankerl
mapped_view: tested on hugetlbfs, and the munmap rounding for it removed, which hugetlbfs makes unnecessary
065a1f7Oct 2
Martin Leitner-Ankerl
mapped_view: re-measured through the header itself, what trust::checked costs a lazy mapping, and the 1M anomaly explained
4884f81Oct 2
Martin Leitner-Ankerl
test/unit/mapped_view.cpp: no memcpy from an empty map's null values() (UBSan, CI's halt_on_error)
ec1ad5dOct 2
Martin Leitner-Ankerl
mapped_view.h: simplify after review, and one exception type for bytes that do not describe a table
94a45f6Oct 2
Martin Leitner-Ankerl
mapped_view.h: a file mapping that owns a map_view over its bytes, lazy and shared by default, because 2 MB pages are worth 1.03-1.13x to a view from 4M to 64M entries and not worth giving up the shared page cache

.claude, CLAUDE.md: what the 2026-10-02 issue pass cost, written down
233f14eOct 2
Martin Leitner-Ankerl
index_container<Bucket>: a value container can name the index container, for a table inside a blob
bad7b42Oct 2
Martin Leitner-Ankerl
load a map from its values and its index without rehashing: index(), map_view, verify()
fc425ceOct 2
Martin Leitner-Ankerl
