* fix(balancers): keep mixed strategies on one observer
Xray resolves Observatory and Burst Observatory through the same global observer feature. When any burst-required strategy is present, keep all observer-backed balancer selectors on burstObservatory and remove the regular observatory so mixed leastPing configs cannot generate two competing observer blocks.
* test(balancers): cover observer strategy combinations
Exercise the observer sync matrix for random, round-robin, leastPing, and leastLoad balancers. Include mixed and stale-observer cases so the panel keeps only the observer type that Xray should consume.
* fix(balancers): clarify observer empty state
Update the Observatory tab empty hint to describe the actual auto-managed cases. Least Ping, Least Load, and fallback Random or Round-robin balancers now explain why an observer is added before the balancer can choose a target.
* fix(balancers): remove mixed observer switch
Show only the observer settings panel that matches the current balancer requirements. Legacy configs that still contain both observatory blocks now display a warning instead of a tab switch, since saving balancers normalizes the config back to one global observer.
* test(balancers): cover observer cleanup on deletion
Add direct balancer deletion and outbound cascade cases for leastLoad, fallback, and mixed leastPing scenarios. These tests pin that the final unneeded observer is removed, burst switches back to regular observatory when only leastPing remains, and burst remains when a burst-required balancer survives.
* feat(xray): reference-cleanup helpers for entity deletion
When an outbound or balancer is deleted on the Xray page, routing rules and
balancers that reference it must be repaired in the same edit, or the saved
config breaks the core: a dangling balancerTag stops Router.Init (whole core
down), a dangling outboundTag black-holes matched traffic at the dispatcher.
Add pure plan*/apply* helpers that compute and apply the cleanup. A rule is
kept when a destination (outboundTag or balancerTag) remains and dropped when
none does. Deleting an outbound cascades: emptying a balancer selector removes
that balancer too, then repairs its rules in one pass against the full removed
set; fallbackTag and dialerProxy references are cleared and observatories
re-synced.
* fix(balancers): clean routing rules referencing a deleted balancer
Deleting a balancer left routing rules pointing at its balancerTag. xray-core's
Router.Init then fails ("balancer <tag> not found"), the core won't restart and
every inbound drops — the saved config passes CheckXrayConfig (JSON shape only),
so it breaks only on the next restart.
The delete confirm now lists the affected rules (modified vs removed) next to
the existing observatory warning and applies planBalancerDeletion's cleanup: a
rule keeps its outboundTag when present, otherwise the whole rule is dropped.
Adds the shared DeletionImpactList and refCleanup strings across all 13 locales.
* fix(outbounds): clean rules, balancer selectors and dialerProxy on outbound delete
Deleting an outbound left routing rules pointing at its outboundTag (matched
traffic black-holed at the dispatcher), plus stale references in balancer
selectors / fallbackTag and other outbounds' dialerProxy.
The delete confirm now shows planOutboundDeletion's impact and applies the
cascade: rules keep a remaining balancerTag (else are dropped), the tag is
pulled from balancer selectors and fallbacks, dialerProxy references are
cleared, and a balancer whose selector is emptied is removed along with its
own now-targetless rules.
* refactor(xray): share one rule classifier across preview and apply
Code review flagged that the keep/drop predicate was transcribed twice — in
ruleImpacts (the delete-modal preview) and in applyCleanup (the mutation) — kept
in sync only by a parity test. Extract a single classifyRule() that both call,
so the preview can never disagree with what apply actually does.
Also harden balancersEmptiedBy to skip tagless balancers: an empty/missing tag
would otherwise enter the removed set as "" and silently drop every other
tagless balancer (only reachable via a hand-edited config, but a silent data
loss). And remove observersRemovedByDeletingBalancer, orphaned once BalancersTab
switched to planBalancerDeletion.
* fix(xray): null-guard reference cleanup against unvalidated configs
The PR review noted that classifyRule and applyCleanup dereferenced rule /
balancer entries directly, while the sibling propagateOutboundTagRename uses
optional chaining — because fetchXrayConfig falls back to the unvalidated parsed
object when Zod validation fails, a stray null in rules / balancers can survive
into the editor and would throw during the delete preview/apply.
Match that defensive style: classifyRule and balancersEmptiedBy read through
optional chaining, the balancer loop skips nullish entries, and the dialerProxy
walk guards the outbound. A delete on a hand-edited config with null entries now
degrades gracefully instead of throwing.
* feat(balancers): tabbed Observatory/Burst form replacing raw JSON
Replace the raw JSON editor for the Observatory / Burst Observatory sections
with a proper Ant Design form, and split the Balancers page into two sub-tabs:
"Balancer Settings" (the existing table) and "Observatory".
Observers stay fully auto-managed by balancer strategy through the existing
syncObservatories logic: users edit only the tunable probe fields, the
subjectSelector is shown read-only since it is derived from the balancers, and
deleting the last balancer that needs an observer now warns in the confirm
dialog that the observer will be removed too. Overlapping selectors keep an
observer alive while any balancer still references it.
Also add the previously missing pingConfig.httpMethod field (HEAD/GET) and
translations for the new strings across all 13 locales.
* refactor(balancers): tighten httpMethod typing and align connectivity default
Address automated review feedback on the Observatory form:
- Use the ObservatoryHttpMethodSchema enum for pingConfig.httpMethod instead of
a free-form z.string(), and drive the HTTP method Select from its options.
Removes the previously dead enum export and the duplicate local list, and
types the field as 'HEAD' | 'GET'.
- Align the schema's connectivity default with DEFAULT_BURST_OBSERVATORY (the
hicloud URL) so it matches what burst observers are actually created with.
No behavior change.
xray-core's Random/RoundRobinStrategy calls RequireFeatures(Observatory) whenever a fallbackTag is set, so a balancer that declares a fallback but has no observatory aborts startup with 'core: not all dependencies are resolved'. syncObservatories never created an observer for these strategies, crashing the core on any load balancer that used a fallback (the default 'random' strategy with a fallbackTag, exactly issue #5605).
Treat random/roundRobin balancers that set a fallbackTag as requiring the burst observer. Also make the burst observer strictly requirement-driven (mirroring the leastPing/observatory path) so clearing the last fallbackTag drops it again instead of leaving a dead observer that forces needless restarts and probing.
Closes#5605
Add a hot-apply layer that computes a diff between the old and new
generated config and applies only the changed parts through the Xray
gRPC HandlerService and RoutingService, avoiding a full process restart
whenever possible. A restart is still performed when sections that have
no reload API (log, dns, policy, observatory, ...) actually change.
Key additions:
- internal/xray/hot_diff.go: ComputeHotDiff with canonical-JSON
comparison (sorted keys, null=absent, full number precision) so UI
reformatting never triggers a spurious restart
- internal/xray/api.go: AddOutbound/DelOutbound, ApplyRoutingConfig,
GetBalancerInfo, SetBalancerTarget, TestRoute gRPC wrappers
- internal/web/service/xray.go: tryHotApply, ensureAPIServices,
GetBalancersStatus, OverrideBalancer, TestRoute service methods
- internal/web/controller/xray_setting.go: balancerStatus,
balancerOverride, routeTest API endpoints
- frontend: BalancersTab live-status/override columns, RouteTester
component, Restart button removed (Save now hot-applies)
- balancer-helpers.ts: syncObservatories never creates observatory
sections for random/roundRobin balancers (no reload API → restart)
- i18n: balancerLive/Override/routeTester keys added to all 13 locales
