utils.generation_params converted nested arrays to strings recursively,
so a crafted file with a value nested about 900 arrays deep raised
RecursionError, where the browser parser returns a result. The join now
runs on an explicit stack. A JS-parity case with 900-deep values pins it.
* feat(parse): port the browser generation-parameter parser to Python
Adds utils/generation_params.py, a line-for-line port of
extractGenerationParams in web/js/comfy-metadata.js, the parser behind
the gallery, admin and metadata pages. The scan and live monitor can use
it so every surface reads prompts the same way. The JavaScript parser is
unchanged.
The port reproduces the JavaScript value semantics the result depends on
(property order, truthiness, String(), trim(), strict equality, Map keys,
JSON.parse number rounding, and the inputs on which it throws), and runs
its recursive tracing on an explicit stack so crafted graphs cannot
exhaust the Python stack.
Tests:
- behaviour tests for each tracing rule, with JavaScript results as
expected values, including the visit-limit boundary;
- golden vectors of the JavaScript parser's results for every named case
and every PNG fixture, so the comparison runs without Node;
- a live comparison against the JavaScript parser when Node is present;
- a randomized differential test over 9,000 generated graphs and
workflows, coherent and corrupted, including inputs where the
JavaScript throws.
Five deliberate porting mistakes (trim, truthiness, prepend handling,
visit limit, pair slot) each fail the tests. On a 38,602-file output
folder, all 18,491 files with a workflow give identical results.
* fix(scan): link the traced prompt when the pair resolver cannot decide
The output scan skipped every file the pair resolver called ambiguous or
unresolved, so workflows where several samplers share one prompt (a base
pass, an upscale pass and a detailer) never reached the Library from a
scan. It now links the positive prompt the shared parser traces for
those files, the prompt the inspector and the legacy pages show. Files
the resolver decides are stored as before, and graphs without a
recognized sampler keep the legacy extractor (#252).
Read-only scans of a 38,602-file output folder into temporary databases:
- links: 1,500 before, 7,954 after; none of the 1,500 dropped or changed;
- of the added links that differ from the pre-redesign scan, 1,275
replace a number, a LoRA tag, a fragment or a truncated prompt that
scan stored.
* refactor(parse): return a uniform pair from the SameValueZero key
