Issue #2300: a function written inside an object literal became a symbol
only when the object was an `export const`. A plain `const api = {...}`,
an object declared inside an IIFE or a function, and a namespace hung on
the page (`window.WS = {...}`, `ns.mod = {...}`) produced no member nodes,
and no node for `WS` either. Calls made inside those members were credited
to the enclosing constant or lost, and calls into them resolved to
nothing. Script-tag JavaScript, written almost entirely this way, was
mostly missing from callers and impact.
Cause: the TS/JS extractor, and the kernel's tsjs mirror of it, minted
members only for exported object-of-functions; any other literal was
walked as one opaque initializer, and an assignment to a member path was
never a declaration. Resolution had no way to reach a member through
`App.init()`, `window.App.init()` or `App.utils.pad()`.
Fix (extraction, TS and kernel byte-identical): a named object literal
owns its function members (method shorthand, `key: function`, `key: () =>`,
generators; static keys only), whether it is declared at module scope,
in a function body or IIFE, assigned to a path (`window.App = {...}`,
`App.utils = {...}`) or assigned to a plain name at module level
(`dw_page = {...}`). Members are `function` nodes qualified under the owner
(`api::load`, `window.App::init`, `App.utils::pad`), the exported case
included; a path owner is named by its last link and qualified by the
path. Calls in a member are the member's; other values are walked where
they were before. CommonJS exports, prototypes, `this.x = {...}`,
call-argument literals, a name reassigned inside a function, and
generated or minified files keep the old shape. Minified files are now
also recognised by content, in both extractors, and the kernel's
`.min.js` pattern matches the TS one.
Fix (resolution): a member is reached through its object only:
`App.init()`, `window.App.init()`, `App.utils.pad()`, a sibling's
`this.render()`, a `const { init } = App` binding; never a bare `init()`.
A same-file holder is chosen by lexical block (an IIFE's own `App` first);
otherwise a global one (`window.App = {...}`, or a classic script's
top-level `App`) when the caller neither imports nor binds the name.
Arrow members keep the `this` of the method around the literal, in the
`this.x` resolvers too. A dotted-path holder is never reached by its last
name alone, and Svelte's `$store` rule now applies only in `.svelte`
components, so the new local holders are not taken for `$n` in plain
scripts. The lookups read each file once (destructuring patterns only
when the raw text has a `} =`) and keep only the last 32 files' scans.
Contributor PR #2310 (@danusha2345): adopted its model (owner-qualified
members exported or not, path owners, IIFE/local owners, static keys,
no bare-name reach, `<script setup>` contains edges, SFC languages, test
scenarios), re-implemented on current main. Not taken: the
EXTRACTION_VERSION bump (already 28), the extraction-time binding oracle
with its ref/edge metadata and kernel ref patching (replaced by
resolution-time lookups), naming the owner `window.WS`, rewriting
`window.X.m()` ref names, flipping exported members' isExported, and
unrelated bare-call changes.
Verification: new js-object-literal-members suite (native + wasm, 18
tests); the issue's shapes fail on main and the guard test fails without
the guards. kernel-tsjs-parity passes with CODEGRAPH_KERNEL_EXPECT=1
(object-literal owners LF/CRLF, minified bundles); kernel parity sweeps
show 0 diffs on DokuWiki, vue-realworld, TodoMVC, excalidraw and this repo.
Validation (kernel loaded, before = origin/main 023fc311):
- DokuWiki: nodes +85, calls +105; 17 removed edges = 13 moved to the
member, 4 re-resolved from a wrong LinkWizard::init to the right init.
- TodoMVC: nodes +427, calls +148; 306 removed = 226 moved, 33
re-resolved (14 fixed `this.render()`/`this.save()`/`this.track()`, 19
wrong-to-wrong fallback guesses), 47 dropped wrong edges (43 to a
helper local to jQuery Mobile's scrollstart setup).
- excalidraw: nodes +86, calls +75; 34 removed = 33 moved, 1 fuzzy 0.3
guess dropped.
- vue-realworld: nodes +10, calls +11; 7 calls re-resolved from the
ApiService constant to its members.
New self-loops are real recursion, bar one lazily redefined method that
calls itself as written. 81 sampled added edges, 80 correct
(the other is main's own window.open guess, re-attributed). Whole-run
index time, median of 3 interleaved: vue-realworld 1.2s -> 1.2s,
DokuWiki 8.6s -> 9.1s, excalidraw 10.8s -> 10.7s, TodoMVC 16.9s -> 16.9s
(within run-to-run noise).
