fix(core): an all-skipped filter says "no constraint" instead of returning the input - #9080
Conversation
…rning the input
`convertFiltersToAST` skips a key whose value is `null` / `undefined`. That is
long-standing, pinned, and unchanged here: `{ a: null, s: 1 }` still lowers to
`['s', '=', 1]`. What changed is the answer when the skip leaves nothing behind.
The general tail returned the CALLER'S ORIGINAL OBJECT, and that object meant two
different things on the two `find()` routes of `@object-ui/data-objectstack`
(measured against @objectstack/spec 17.4.0 and @objectstack/client 17.4.0):
plain GET /data/acct -> EVERY row
expand GET /data/acct?populate=...&filter={"a":null} -> the a = null rows
The plain route hands the value to `client.data.find`, whose non-AST branch
spreads a plain object's entries as query parameters and SKIPS the null ones, so
nothing was appended. The `$expand` / `$search` route JSON-serialises the same
object into `filter=`, and `{ a: null }` is a well-formed `FilterCondition` the
spec accepts, so it arrived as a real predicate. One authored filter, two row
sets, decided by whether the query happened to expand a lookup.
The tie is broken by what the function already says about the key rather than by
inventing a meaning for it: the loop's `continue` is the ruling, so carrying it
to the wire is `undefined`. An author who meant the predicate spells it
`{ a: { $null: true } }`.
Same ANSWER as the TRUE-identity fold beside it, deliberately not the same state:
two counts, two guards, so a filter that MIXES the kinds (`{ $and: [], a: null }`)
still returns the object and stays an open question elsewhere.

条款② 席内复核 — PASSReviewing seat: The declaration is right, and on which limb
The argument that decides it, and it is the dev's, not mineI came into this review with one objection: resolving the two-route disagreement toward
⇒ this is 恢复不变量: a function made consistent with its own declared, pinned semantics. Not a new rule, and not this seat inventing one.

Authority: the in-seat clause-② review of record on this PR, verdict PASS — comment 5627569868.
Pre-landing check ② (contract-review.md:42) satisfied on the record, not waived. The dev hung both carriers additively with the draft PR per os-dev.md:288, read both back, and reported check-clause2-carriers --pair 9080 exit 0 — both carriers agree in the fixed spelling. The full hang → in-seat review → clear sequence is on this PR in that order. ⭐ Third pair this session to run it correctly end to end, and the first where the brief was right the first time.
⛔ pm:dispatched retained on objectui#9020 until this lands, at which point pm:* and the assignee are stripped explicitly — Fixes has never stripped either (29 for 29).
⚠️ One correction owed to this PR's own body, and it runs against something this seat wrote
The body carries the session URL as prose, with the reason: "the platform appends its own footer block on every body EDIT, and a second rule-line footer is the result otherwise." The dev measured it on this PR — CREATE kept the session-URL footer byte-intact, the first EDIT produced two footers, a corrective write ending in the bare form came back byte-identical at 12170 → 12170 bytes.
update_pull_request path, both times ending in the session-URL form, and read back one footer with the full …/code/session_… intact both times.
⇒ both readings stand, and the discriminator is therefore not the footer form alone — the dev's own hypothesis. It appears to include the channel: this dev went over repo-scoped REST (declared, mcp_calls: 0), this seat went over MCP. Recorded as a refinement to lane fact ㉜ rather than a correction to either party; ⛔ neither observation repeals the other, and the honest state is "conditional, condition not yet isolated." Whoever next edits a PR body should read it back regardless — which is the standing rule and the reason both of these are known at all.
Marking ready for review and arming on all-checks-green.

Fixes #9020
convertFiltersToASTskips a key whose value isnull/undefined. That islong-standing, pinned, and unchanged here —
{ a: null, s: 1 }still lowers to['s', '=', 1]. What changed is the answer when the skip leaves nothing behind: thegeneral tail returned the caller's original object, and that object meant two
different things on the two
find()routes of@object-ui/data-objectstack.The disagreement, re-driven on today's
origin/main(ZONE 2 A)Measured on
2a79e847b, with the branch point recorded before the first edit. Bothroutes driven through the real adapter with a recording
fetch, both wire values thenfed to
ValueDataSource's matcher over one four-row fixture:convertQueryParamsthenclient.data.find)/api/v1/data/account?rawFindWithPopulate)/api/v1/data/account?populate=owner&filter={"a":null}The plain route's non-AST branch spreads a plain object's entries as query parameters
and skips the null ones, so nothing at all was appended and no
filterparameterwas sent. The expand route JSON-serialises the same object into
filter=, and{ a: null }is a well-formedFilterCondition—nullis in the spec'sACCEPTED_FILTER_COMPARAND_TYPES, andFilterConditionSchema.safeParse({ a: null })succeeds — so it arrived as a real predicate.
The disagreement is live. None of the three same-day landings closed it:
objectui#9019's fold needs a TRUE-identity combinator (
trueIdentityGroupsis 0 here),objectui#8996's
$icontainsidentity never runs (the key is skipped before any operatormachinery), and objectui#9049's
refuseTextComparandthrows rather than skipping, so itcannot reach this tail at all.
objectui#8770's fold does NOT already cover it (ZONE 2 B)
Measured, same run:
convertFiltersToAST({ $and: [] })isundefinedwhileconvertFiltersToAST({ a: null })returned the input and was reference-identical toit. Two distinct arms of one tail, reached by two different inputs.
Which "constrains nothing" answer this takes, and why (ZONE 1 3b)
The same ANSWER as objectui#8770 —
undefined— reached through a SEPARATE count anda SEPARATE guard.
There is no second spelling to choose. This dialect expresses "no constraint" as the
absence of the slot:
lowerLogicalGroupsays so for the TRUE identity, and['and']— the "obvious" empty group — is
isFilterASTFALSE. The two candidate repairs were(a) make a null-valued key mean a predicate, which breaks the skip pin and moves every
caller's row set, and (b) carry the skip's own answer to the wire. The ruling forecloses
(a), and (b) is what the loop already says: the key contributes no condition, so a filter
made only of such keys contributes none either. An author who meant the predicate has
always been able to spell it
{ a: { $null: true } }->['a', 'is_null', true], andthat is pinned on both routes.
They coincide on the answer; they are not merged as a state. The tail now carries two
counts and two guards, each keyed on "EVERY key was of MY kind":
trueIdentityGroups— objectstack#5322's ruled identity, decided bylowerLogicalGroup;skippedNullKeys— this file's own tolerance, made self-consistent.The evidence that they were told apart rather than merged is the case that satisfies
neither:
{ $and: [], a: null }and{ $and: [], b: undefined }still return theobject, even though each of their keys alone now folds. A single merged counter would
swallow both. Whether they should fold is objectui#9030's open question, and this PR does
not answer it.
The oracle is the disagreement, not a shape on either route (ZONE 1 2)
packages/data-objectstack/src/filter-all-skipped-two-routes-9020.test.tsdrives everycase down both routes and compares the two readings with each other before either
is compared with a literal, so a repair that left them disagreeing differently fails even
if it satisfies every shape assertion. Both halves are present because either alone
passes on something worse: agreement alone passes on two routes agreeing on the wrong
answer, and a row set alone cannot tell "honoured" from "dropped" for a filter whose
correct answer is every row — so section 0 proves the fixture distinguishes every-row
(1,2,3,4) from the
a = nullsubset (2) before any of it is read that way.Pins UPDATED, not routed around (ZONE 2 E)
Five existing assertions pinned the input-returning tail. Every one is a pin whose card
was asserting "I did not move the tail", so each is re-pointed rather than deleted, and
each keeps its own control:
filter-converter.test.ts— "should return original filter if empty after filtering";filter-true-identity-8770.test.ts— the all-null case in "the non-combinator tail is untouched";filter-date-comparand-8555.test.tsandfilter-exotic-comparand-8567.test.ts— "scalars, null and undefined are exactly what they were";filter-text-comparand-9001.test.ts— "the TRUE-identity tail counts exactly the keys it counted before".Only the first two were predicted; the other three were found by running, and are recorded
as such rather than quietly fixed. Each updated case gained the sibling assertion
(
{ a: null, status: 'active' }still lowers to['status', '=', 'active']), so the pinthey were protecting is now asserted where it was only implied.
Scope
{ $and: [] }keepsundefined;{ $or: [] }keeps its FALSE leaf and its zero rows.{}and{ a: {} }keep the object — neither has a skipped key, so neither guard fires.{ $and: [], a: null }keeps the object — objectui#9030.different acceptance probe.
Acceptance notes
buildDatasetDrillFilter(packages/core/src/utils/dataset-format.ts) writes{ field: null }for the empty bucket, verbatimraw === '' || raw === undefined ? null : raw, and that filter reaches this converterthrough
DrillDownDrawer->ObjectDataTable->ObjectGrid'stoFilterNode.It is already broken today, independently of this PR, and that was measured, not
assumed:
So an empty-bucket drill-through already returns a superset whenever the drill has a
second dimension or the dashboard has any filter applied. What this PR changes is the one
remaining case — a single drill dimension, no runtime filter — which today is honoured
only when the grid happens to auto-expand a lookup (
buildExpandFields), i.e. exactlythe "decided by something unrelated to the filter" hazard this card is about. After this
PR that case is consistently "every row" instead of intermittently correct. The repair
belongs at the producer (
{ field: { $null: true } }), per AGENTS.md 0.1, and it isfiled separately: it would touch 14 shape pins across
plugin-dashboardandplugin-report, which is a different verification surface and another seat's file face.Other observations, noted and not filed:
exportDownloadandfindOnebuildfilter=through the sametranslateFilterToAST/rawFindWithPopulatepair, so they inherited the expand-route reading and now inheritthe corrected one. No separate defect: they were never a third
find()route.ValueDataSource's matcher reads{ a: null }as strict equality againstnull— itselects a row with an explicit
a: nulland not a row missingaentirely, where['a', 'is_null', true]selects both. A real difference between the two spellings, andnot this card's; carrier for it: whoever takes the producer card above.
Ablation — predicted in writing, then run
Prediction, recorded before the mutation: deleting the new guard turns the three
objectui#9020 assertions RED and leaves every control GREEN on both legs, direction
RED (not "more diagnostics", not a reversal — the guard's only effect is a return value).
Resolution path stated with it: the root vitest config aliases
@object-ui/coretopackages/core/src, so there is nodisthop on this route and the on-disk edit is whatruns — which is why the proof below is a blob hash and a grep, never an exit code.
1 -> 0, marker count0 -> 1, blob87ce8f34… -> ad7f50d9…1 -> 0, guard count0 -> 1, blob back to87ce8f34…,git diff HEADemptyThe restore is
git checkout HEAD -- PATH(never baregit checkout --, which would takethe mutation back out of the index), under a
trapon absolute paths, and it is proven bythe empty diff and the matching hash rather than by the command's exit code.
Observed vs predicted: direction and membership matched; the count did not — 24
assertions rather than the 7 cases named, because three
it.eachtables expand. Recordedas a refinement rather than presented as a hit. Every control held, including the two the
dispatch named: a filter with live keys lowered exactly as today, and objectui#8770's
{ $and: [] }kept its own answer — as did{ $and: [], a: null },{ $or: [] },{}and
{ a: {} }.Verification
All under the shared verification lock; the seconds are shared-box readings.
