📝 WalkthroughWalkthroughThe PR adds PL/iSQL package and local ChangesPackage Record Type Support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds package record-type support, but repeated type lookups can grow backend memory because allocated type metadata is not reused; this is a bounded runtime risk requiring explicit owner follow-up, while the remaining test and diagnostic issues are localized and non-blocking.

and line 457, and src/pl/plisql/src/sql/plisql_package_type_record.sql lines 1-8
and line 454, list only NOT NULL and DEFAULT as rejected field-level syntax and
change “three checks above” to reflect the two remaining checks. Apply identical
wording in both files.

- Around line 1984-2010: Update the rowtype lookup in the type_is_rowtype branch
to use lookup_rowtype_tupdesc_noerror instead of lookup_rowtype_tupdesc, and
only iterate over the descriptor when the lookup returns non-NULL. Preserve the
existing unmatched-field behavior by releasing any valid descriptor and
continuing to return NULL when no descriptor is available.
In `@src/pl/plisql/src/pl_gram.y`:
- Around line 747-834: Wrap the record_attr_list parsing in a private namespace
using plisql_ns_push and plisql_ns_pop, matching the cursor-argument production,
so field names are not added to the enclosing scope. Preserve the field datums
and their new->varnos references after popping the namespace, and update the
action’s $6 references to $7 to account for the inserted mid-rule action.
- Around line 5112-5128: The package-type fallback logic should use
parse_by_pkg_type for both standard and current-package lookups so PKG_TYPE
entries resolve correctly. In the current-package path around
plisql_compile_packageitem and plisql_parse_package_type, quote fn_signature as
a package identifier or construct the TypeName from a name list before appending
string, preserving package names containing dots or spaces.
In `@src/pl/plisql/src/pl_package.c`:
- Around line 219-253: Update the PLISQL_NSTYPE_ROWTYPE branch to inspect
list_size and name_start, and reject any trailing name components instead of
returning the record type. Preserve the existing type-resolution behavior only
for an unqualified ROWTYPE reference, using the nearby PLISQL_NSTYPE_REC
handling as the pattern for distinguishing qualified names.

refer to type rather than record, accurately stating that type must remain a
dedicated token and absent from pl_gram.y’s unreserved_keyword production.

- Around line 559-593: Extend the PL/iSQL package namespace test with duplicate
record-type declarations and a record type whose name collides with a package
variable, using the existing declaration flow around rec_t and package members.
Add expected output that captures the duplicate-name errors, preserving the
current field-name isolation cases.
In `@src/pl/plisql/src/pl_package.c`:
- Around line 253-263: Cache the PLiSQL_type created for the package record type
on the relevant PLiSQL_row or package entry, and reuse that pointer on
subsequent lookups instead of calling plisql_build_datatype repeatedly. Update
the lookup flow around psource and the existing fn_cxt allocation so
construction occurs only once while preserving the returned type’s
package-lifetime ownership.
In `@src/pl/plisql/src/sql/plisql_package_type_record.sql`:
- Around line 311-341: Extend the test package specification around
test_pkgtype_params and rec_t with a package-level variable declared as rec_t,
then exercise that variable from the test block through existing package
functionality such as fill_out and describe. Ensure the assertions or notices
verify its fields and preserve coverage of package-datum instantiation and
package state.

Add grammar support for declaring a record type in a package spec or
body:
TYPE rec_t IS RECORD (a NUMBER, b VARCHAR2(50), c FLOAT);
The type is parsed as a PLiSQL_row and namespaced separately
(PLISQL_NSTYPE_ROWTYPE) from record variables (PLISQL_NSTYPE_REC), so
lookup code can never confuse a type declaration for a variable. Its
field list is used to build and bless a TupleDesc at declaration time,
giving the type a real RECORDOID typmod usable anywhere a datatype is
expected: variable declarations, return types, IN/OUT parameters,
%TYPE, and package-qualified references, including cross-package.
Record variables can be instantiated and returned without a prior
full-row assignment, and "SELECT * FROM pkg.func(...)" resolves the
composite return type without needing a column alias list.
"TYPE ... IS TABLE OF" is parsed but rejected with a clear
"not supported" error rather than implemented.
NOT NULL and DEFAULT on a field are rejected at compile time: neither
can be honored (no per-field default storage, and no way to satisfy a
NOT NULL field without one); accepting them silently used to crash or
silently drop the default.
A field whose own type is composite (another package record type, or
a named composite type) now carries its real typoid/typmod into the
outer TupleDesc, and nested reads ("v.field.subfield") work via a new
FieldSelect-construction extension to resolve_column_ref(). Nested
field-by-field *writes* work when the field's own type is a named
composite type, but not when it's itself a package record type --
that would need a resulttypmod slot on core's FieldStore node, out of
scope here; it fails with a clean error instead of crashing.
Also fixes: a "tupdesc reference ... not owned by resource owner"
crash for named-composite-type record variables inside packages
(get_plisql_rec_tupdesc()'s two TupleDesc ownership models were being
released unconditionally); a latent copiable_size under-computation in
plisql_finish_datums() that could undersize the datum-copy workspace
on repeated compile passes over a package's functions; and a memory
context lifetime bug in cross-package/self-qualified type references.
New plisql_package_type_record.sql regression suite covers declaration,
package-qualified and cross-package references, IN/OUT parameters,
the rejected field clauses, nested composite fields, and the type/
variable confusion guards above (including via %TYPE).

The comment at lines 43-46 states that a type declared in a package body is not visible outside it, including through a qualified reference. No statement in this suite asserts that. Add a case that references
test_bodyonly_record.rec_tfrom another package or block and record the resulting error. This locks in the visibility boundary that the comment claims.♻️ Suggested addition after line 68
