aconfig parses an empty TOML array (rules = []) as a slice holding one
empty string, which the router then treated as a real rule. Empty rules
can never match a real domain; Add and Replace now drop them.
- countingConn batches per-domain attribution (32KiB/500ms) so the relay
hot path pays two atomics per I/O instead of a global mutex; Close drains
- Precompute OTel byte attributes to drop per-I/O allocations
- suffixtree: indexMap only for nodes with >=8 children; Match stays
read-only for concurrent queries
- Soft Go memory limit (128MiB default, GOMEMLIMIT/SOWER_MEMORY_LIMIT_MB
override) cuts resident memory from ~240MB to ~130MB on the default
ad/china/gfw rule sets
- Split stats.go into snapshot/eviction/counting by responsibility
The rules page can now answer 'what happens to this domain?': RuleSet
gains MatchRule, a linear scan that returns the first matching rule under
the same suffix semantics as the suffix tree, and GET /api/rules/test
(auth) reports per-category hits plus the route a connection would take
(block > direct > proxy priority; 'auto' with a note when no rule
matches, without performing live detection).
- Rules page gets a domain test input with route badge, per-category
match rows, and the fallback note
- tests: MatchRule agrees with Match, fake + endpoint coverage
The rules page froze because block rules (164k+) were all transferred
and rendered at once. The list API is now paginated and searchable:
- GET /api/rules?category=X&q=...&offset=N&limit=M returns a page plus
the total match count; q is a case-insensitive substring match
(alloc-free scan in RuleSet.ListFiltered), limit clamps to 1000,
default page 200.
- POST/DELETE /api/rules now return 204; the frontend refetches the
currently loaded range so totals stay accurate.
- Rules view: server-side search box with 300ms debounce, load-more
button appends pages, count badge shows loaded/total.
Measured on the live box: first page 0.5ms, 164k-rule scan ~22ms.
RuleSet retains the raw rule list alongside the suffix tree so rules can be
listed, added and removed at runtime. Removal rebuilds the tree from the
retained list; startup batch loading keeps the old single-compaction flow.
Router.BlockRule/DirectRule/ProxyRule migrate to *RuleSet.
