This made every compiled binary containing a record literal unloadable: $ unison run.compiled mainbin.uc unknown FnTag word: 7 (585 bytes remaining) Also guard the RecordT branch of getValue on the payload version, matching its DataT and ContT neighbours, and hash an explicit field count for record terms and record patterns. Every token in those flat name/value runs happens to be self-delimiting today, so this is insurance rather than a fix for a demonstrated collision - but record hashes are permanent, and the count costs one token.

Nested record patterns therefore never typechecked at all: g : { a: { b: Nat } } -> Nat g = cases { a: { b: b } } -> b --> I found a value of type: {b: Nat} where I expected to find: {b: 𝕩| ...} Binding the applyM results fixes nesting to arbitrary depth, and also fixes the general case where unifying one field refines another field's type. subtype's record case also had MissingRecordField and UnexpectedRecordField swapped: This means the field is present only in the subtype, which is an extra field, and That means the subtype is missing a required one. The transcript stanza commented "nice error if we have additional unexpected fields" was rendering as "I expected this record to have the field address" about a record that plainly had address. The Cause doc comments disagreed with how Extractor/TypeError/PrintError bind the arguments, so correct those too. Also: - equate0 now requires matching FieldBehavior, so an open record no longer equates with a closed one in an invariant position, and reports the right constructor per direction. - instantiateR's record case recursed into instantiateL; the two agree for monotype fields but not for arrow- or forall-typed ones. - RecordPatternMatchOnNonRecordType was never constructed. Raise it when the scrutinee is already known not to be a record, and promote it and PatternMatchedMissingField to real TypeErrors that point at the pattern rather than falling through to the raw-cause bucket. - renderPattern passed an empty variable supply to prettyPattern, so it crashed on any pattern containing a variable. Latent for its existing callers, which render coverage-checker output using Unbound. - Drop the resolved TODOs on discardCovariant's record case and checkWanted. - Normalize record type printing to {a: Nat | ...} in both printers. structural-records.md was a stale pre-idempotent transcript whose committed output recorded a crash at a Context.hs line that no longer exists; its two unique cases (list unification, mismatched field types) move into new-records.md.

Any refutable subpattern crashed the coverage checker outright: lit = cases { x: 0 } -> "zero" _ -> "other" --> error "expected Pattern-5 to be in UFMap" Two things were missing. The coverage checker had no record constraint at all: Literal.PosRecordLiteral carried no field types, addLiteral declared the *record* variable -- which is the scrutinee, already declared -- rather than the field variables, and addConstraint's handler was a stub that always succeeded. So records participated in neither redundancy nor exhaustiveness reasoning, and declVar had been weakened from alter to insert to hide the resulting double declaration. Records are now modelled as what they structurally are: products with exactly one constructor. A new Vc'Record constraint holds a variable per matched field; addConstraint merges a new positive constraint with any existing one by equating shared fields, mirroring PosCon; and a new RecordType case in EnumeratedConstructors gives withConstructors the field types so instantiation walks into them. declVar is restored to alter with its guard. Falling out of that: - A record with an uninhabited field is now itself uninhabited, so Either { x: Void } Nat no longer demands a Left case. The transcript documented this as known-wrong. - Uncovered-pattern suggestions name fields: {age: _} rather than _, and nested ones reach {a: {b: None}} rather than stopping at {a: _}. Fixing coverage then exposed the next layer, unreachable until now: in Runtime.Pattern, PType required record schemas to be equal, so two cases matching different field subsets hit "inconsistent pattern matching types", and decomposeRecPattern emitted each row's own fields positionally, so rows of differing length misaligned when buildMatrix transposed them. Rows are now decomposed against the union of the fields matched anywhere in the column, one slot per field. The filler has to be a Var rather than Unbound: by that point prepareAs has rewritten every user-written _ as a Var, so an Unbound head is the marker chooseVars uses to skip wildcard-decomposed rows. Also drops the dead RecordSpec type and fixes prettyPmGrd, which rendered its field map through Show.

Since Universal.compare underpins Map and Set, two codebases holding the same definitions could iterate or dedupe differently. The cross-schema branch was worse: `compare rr1 rr2` on interned schema ids, with no semantic meaning at all. A record is now `GRecord !RecordShape !(Vector Val)`, where slot i holds field i of the shape in ascending field-name order. `RecordShape` carries the field names and is reachable from the value, which is what lets `Eq` and `compareClosure` -- both pure, with no access to the code cache -- order records by name. Ordering two records of *different* shapes is reachable: they can be compared once wrapped in `Any`, which erases their types. Those compare their sorted field-name lists, so `Any {a: 1} < Any {b: 1}` and a shape whose fields are a prefix of another sorts first. The shape also carries each field's slot, which is what `RecUnpack` needs. It can't bake slots into the instruction: one pattern matches records of several shapes, and the same field sits at a different slot in each -- `getA` below finds `a` at slot 0, 1 and 2. getA : { a: Nat | ... } -> Nat getA = cases { a: a } -> a getA { a: 1, b: 2 }; getA { z: 9, a: 7 }; getA { x: 1, y: 2, a: 42, zz: 3 } Because the names now travel with the value, reflectValue is a few lines rather than a plumbing exercise, so `Value.value` on a record no longer aborts the process. Verified end to end: reflect, serialize, deserialize, reify, read the fields back, using unsorted source order so a misordering would show up. Also in this change: - cacheAdd0 derives the record schemas it needs from the groups it is given, via a new ANF.groupRecordSchemas. cacheAdd previously passed mempty, so Code.cache_ on record-bearing code hit "unknown record schema"; codeValidate threw outright on `error "TODO: recordRefsFromCode"`. Both now work. This also lets the Tm.recordSchemas plumbing through Interface be removed -- it only saw surface terms, never patterns. - codeValidate ran `evaluate` on the State action rather than its result, so it forced nothing since emitCombs became stateful. - Field names no longer need pre-registering in cacheAdd0; building a shape during emit interns them, so RefNums.recField goes away and registration has one mechanism instead of two. - Deletes the abandoned FieldTag representation: the newtype, its unused get/put pair in Serialize, the underscore-prefixed pair in MCode/Serialize, fieldNameLookup, and the unused MCode.FieldTags. - recordRefLookup reports through internalBug rather than a raw error.

OutputMessages has no runtime handle, so supplying the real mapping there would have meant carrying it in the error payload. Now that a record value carries its shape, and the shape carries the field names, decompile reads them straight off the value. That makes the whole FieldRef -> Text parameter dead, so this removes it from decompile, decompileForeign, decompileCtx, prettyError and prettyRuntimeExn rather than threading anything new through. > boom = bug { name: "Alice", age: 30 } I have encountered a call to builtin.bug with the following value: {age: 30, name: "Alice"} Co-Authored-By: Claude Opus 5 Claude-Session: https://claude.ai/code/session_01RSRrHY56U2R3UbZrj6Zacb --- .../src/Unison/CommandLine/OutputMessages.hs | 4 +-- unison-cli/src/Unison/Main.hs | 13 ++++----- .../src/Unison/Runtime/Decompile.hs | 26 ++++++++--------- .../src/Unison/Runtime/Interface.hs | 24 +++++++--------- .../transcripts/idempotent/new-records.md | 28 +++++++++++++++++++ 5 files changed, 56 insertions(+), 39 deletions(-) diff --git a/unison-cli/src/Unison/CommandLine/OutputMessages.hs b/unison-cli/src/Unison/CommandLine/OutputMessages.hs index 7c7593053f0..1079858ab24 100644 --- a/unison-cli/src/Unison/CommandLine/OutputMessages.hs +++ b/unison-cli/src/Unison/CommandLine/OutputMessages.hs @@ -716,9 +716,7 @@ notifyUser dir issueFn = \case <> " with the codebase, or the term was deleted just now " <> " by someone else.

It binds tighter than application, so `f r@x` is `f (r@x)`, and it chains: `r@a@b@c`. `@` was chosen over `.` deliberately. `r.x` lexes as a single wordy identifier, indistinguishable from a qualified name, so it would have needed a resolution-order fallback -- rewrite only when the whole name resolves to nothing but some prefix does -- which makes the meaning of `r.x` depend on what is in scope. It would also have been identifier-only: `(mk 1).a` does not fail today, it silently parses as `mk 1 .a`, applying `mk` to the absolute name `.a`. Teaching the lexer otherwise means changing how `.` is tokenized. `@` needs none of that. It already lexes as its own token, because as-patterns depend on it, so `r@x` is three tokens and the left side can be any expression: `(mkRec 5)@v` and `{v: 9}@v` both work. The `@` must be adjacent to both sides, which keeps it from reading as an infix operator and keeps `x@(Some n)` as-patterns working unchanged. There is no new term form. `base@field` desugars to a single-field record match, which typechecks to `{field: t | ...} -> t` through the existing pattern machinery and compiles to the existing RecUnpack instruction -- so no hash, serialization, ANF or runtime changes. TermPrinter recognizes that shape and prints it back as `base@field`, parenthesizing the base when needed, so `view` shows the syntax that was written. The generated binder is named `field` rather than `_field`: a leading underscore makes it a wildcard when the printed form is re-parsed, which silently dropped the binding and broke the round trip. One limitation: a function that is *exactly* one projection still prints as `cases {a: field} -> field` rather than `f r = r@a`. Preferring the projection form there means the printer has to invent a name for the lambda variable, and `cases {x: x} -> x` -- the same term, differing only in that name -- then printed as `f a8qfpevfug1 = a8qfpevfug1@x`. The `cases` rendering is the better of the two, and it round-trips. Also reworded two record errors that said "pattern" for what the user wrote as a projection, and adds records, record patterns, destructuring binds and projections to the round-trip corpus -- the namespaces come back identical.

Both directions raised `error "TODO"` on records, so a rule whose LHS was a record pattern crashed -- and so did any `case` rule at all applied to a definition that merely contained a record pattern somewhere. Both directions are the obvious symmetric pair: a record pattern becomes a record literal term and back. The subtlety is variable order. `intop` assigns the case's abs-chain variables in traversal order, and `matchCaseFromTerm` recovers them with `ABT.allVars`, so the two have to agree. For a record both go through the `Map Text` instances -- `traverse` on the way in, `Foldable` on the way out -- which visit fields in ascending key order, the same order the parser binds them in. That falls out for free, and a rule that swaps two field subpatterns rewrites `{x: p, y: q} -> p + q * 2` to `{x: q, y: p} -> p + q * 2`, carrying each binding to the field it was swapped onto. Also drops the `Apps' (Record' _) _args` case from `toPattern`. Unlike a constructor, a record literal is never applied to arguments, so that shape isn't a term that could have been a pattern; it now falls through to `Nothing` like any other non-pattern. Note that a bare `_` in a rule LHS still doesn't work as a wildcard, in a record pattern or anywhere else -- `case Some _ ==> None` fails the same way. `_`-prefixed names do work, and that's what the transcript uses.

Nothing caught it because this branch was only ever verified with transcripts, and `stack build --test` was never run. `SCache` gained three fields -- `frs`, `rsLookup`, and `rfm` -- and `genStoredCache` was never extended, so the `StoredCache` round-trip property test failed to typecheck. The misalignment had also pushed `mempty`, the "we don't yet generate supergroups" placeholder, off the supergroup map and onto the new `Word64`, where it still typechecked as an empty generator. It's back where its comment says it belongs. BiMaps are generated through `fromMap` on purpose. The codec stores only the forward map and re-derives the backward one, so a BiMap built any other way can carry a backward map that doesn't follow from its forward map -- and then the property fails on BiMap's invariants instead of on the codec. Two more breakages fell out of the same blind spot: `RefNums` gained `recNum`, and `emitCombs` now returns `State RecordFieldMappings`, so `testLift` needed both a fourth stub and somewhere to run the state. Note the stubs stay hand-written rather than using `emptyRNs`: every one of that value's lookups throws, and `emitCombs` calls them. Also worth knowing that this test was previously asserting nothing -- `cs` was an unapplied `State` function, so the bang pattern forced a closure. Making it compile is what made it start testing. `-Werror=incomplete-patterns` wanted `MatchRec` and `FRec` in the ANF test's denormalizer. Implemented rather than stubbed: a record match denormalizes to one irrefutable `RecordLiteral` case, and `FRec` is the only `Func` that isn't applied to its arguments -- they are its field values, in ascending field-name order. Both are currently unexercised, because no `testANF` case builds a record; they are written from the field-ordering invariant, not from a passing test. Adds `emptyRecordFieldMappings` next to `emptyRNs` so the test doesn't hardcode `FieldRef 0`; `Machine/Types.hs` now uses it in place of its local `initRFM`. Results: 74 + 157 + 296 + 2 + 47 pass in core1, syntax, parser-typechecker, share-api and cli, and 304 pass in runtime. 392 transcripts still pass and ormolu is clean. One runtime test still fails, on trunk rather than here: `ffi.dynamic.fixed prefix is not promoted` gets `Left BadInit` where it expects `Right ()`. `BadInit` means the system libffi's `ffi_prep_cif_var` rejected an unpromoted fixed prefix. The test and the code under it arrived with the variadic-FFI merge and neither exists at this branch's merge base, and none of the 70 files this branch touches is an FFI file, so it looks like a platform-specific failure on macOS arm64.

Fixed in `Unison.Pattern`, which is the instance that gets used, and in `Unison.Hashing.V2.Pattern`, which has the same omission. The visible symptom was `sfind`: scratch/main> sfind litRule 😶 I couldn't find any matches. against a definition that literally contains the rule's `{x: 0}` pattern. `sfind` reaches pattern equality through `containsCaseTerm` -> `hasSubpattern`. `rewrite` doesn't, which is why the `@rewrite case` work passed its tests over this bug: it compares patterns after converting them to terms, and the term `Eq` already had its `Record` case. A transcript case now covers the `sfind` path. Found by adding the record cases to `testANF` that the last commit left owing. Two of the four failed with expected and actual printing identically -- the tell for an `Eq` that ignores a constructor. So `MatchRec` and `FRec` in the ANF test's denormalizer, added blind last commit, were right; what they were being compared against was not. Those four cases also pin the field-ordering claim: `{b: x, a: y}` lays its fields out in ascending name order, not source order. Note the derived `Ord (Pattern loc)` still compares locations while this `Eq` ignores them. That inconsistency predates records and is left alone. Verified: 392 transcripts pass, round trip unchanged and namespaces identical, and core1/syntax/parser-typechecker/share-api/cli all pass. Runtime is 304 passed with 9 `anf.denormalize` cases, up from 5, and still the one pre-existing trunk failure in `ffi.dynamic`.
