tooling: let the raw-handle ledger declare a relocation - #10721
proggeramlug wants to merge 2 commits into
Conversation
`raw_handle_debt.py --no-raise-vs` compares ceilings strictly per path, so a pure file move — which the 2000-line cap forces regularly — reads as new debt: the bare run demands the emptied source's line be deleted, and the merge-base run then rejects the destination as "was not listed at the merge base", though the total never moved and the bodies are byte-identical. A ledger entry may now carry `# moved-from: <path>`. The destination is credited with what the source actually surrendered between the base and head ledgers, and nothing else: the total check is untouched, the credit is bounded by a real reduction in the same diff, two destinations sharing one source drain one pool, and the annotation goes inert once the move lands. A malformed entry comment is now a parse failure rather than an ignored comment, and `--update` carries surviving annotations through (writer split out as `render_ledger` so the round trip is assertable). `--self-test` +12 cases: undeclared move still rejected, declared move and a 1+1 three-way split pass, laundering / over-draw / double-spend / stale annotation / self-reference each rejected by their own diagnostic. No ceiling changed.

`e2e-scoped` has been red on every PR since merge train 218 (v0.5.1596),
failing at "Compute e2e suite scope" in ~16s:
ci_e2e_scope: these crates/perry-codegen/tests/*.rs suites are in neither
SOURCE_SUITE_MAP nor SUITE_EXCLUSIONS: error_subclass_field_init,
typed_collection_receiver_guard
Both suites arrived in 6925754 (#10443/#10446, train 218) and nobody
classified them, which is exactly the condition #7708 added this assertion
for. The failure is content-independent, so it reddens PRs that cannot
possibly have caused it -- #10721 (a Python script) and #10722 (a .ts
fixture) both carry it.
Mapped rather than excluded: both are cheap in-process suites of the shape
SOURCE_SUITE_MAP exists for, and both passed when train 218 ran them as
diff-named suites (2 and 3 tests, 0.01s each). Excluding them would have
hidden working coverage; SUITE_EXCLUSIONS is for a named failing test with
an issue number, which neither has.
Verified discriminating, not merely present: with either entry deleted
`--self-test` exits 1 naming the suite, and exits 0 with both.

Reject duplicate ledger paths.
A later unannotated entry overwrites ceilings[path] but retains moves[path] from an earlier duplicate. --no-raise-vs can then apply the earlier relocation annotation to the later ceiling.
Reject duplicate paths before updating either dictionary.

Do not report none raised after an accepted relocation.
A declared relocation can raise the destination ceiling when the source provides sufficient credit. Change the message to state that no uncredited ceiling was raised.

Landed in merge train 224 (#10742), released as v0.5.1603 — main is now Closing rather than merging is how trains work here: the PRs were cherry-picked onto one tree, validated together, and landed under the train's own commit, so GitHub cannot mark this one merged even though your change is on main. One deliberate divergence, for #10719 only: the train carries Validation: all nine cheap gates, |
1 participant
scripts/raw_handle_debt.py --no-raise-vs <base>compares recorded ceilings strictlyper path and treats any path absent at the merge base as a raise. That is right for new
debt and wrong for a pure file move — which
scripts/check_file_size.sh's 2000-linecap forces regularly.
Splitting a listed module makes the bare run demand the emptied source's line be
deleted (rule 3: "ceiling of 4 matches nothing — DELETE its line") and the destination
listed, whereupon
--no-raise-vsfails withalthough the total is unchanged (
906 (baseline 906)) and the moved bodies arebyte-identical. The two required invocations of one gate disagreed about the same tree.
#10565 escaped only by luck: all four of
object/native_module.rs's sites sat in oneblock, so a different split carried none. A file whose debt is spread across it could
not be split at all without first paying the debt down.
What this does
A ledger entry may declare where its debt came from:
--no-raise-vscredits the destination with what the source actually surrenderedbetween the merge base and head (
base ceiling − head ceiling, floored at zero), andwith nothing else.
Per-path monotonicity becomes total monotonicity plus one declared, reviewable
transfer that names its source in the diff. That is the deliberate boundary, and the
docstring says so rather than implying otherwise: a text ratchet cannot tell a move from
a rewrite, so a diff that genuinely cleans four sites in A while adding four unrelated
sites in a new B can spell that as a relocation. What the gate still guarantees:
launder new sites;
count cannot be spent twice;
about both paths the source surrenders 0, so a later raise on the destination is
rejected exactly as before. A stale annotation is a comment, not a standing permit.
Two supporting fixes, each of which would silently revoke a relocation the same commit
declared: a malformed entry comment (
moved_from:, or any other trailing comment) is nowa hard parse failure instead of an ignored comment — otherwise the typo surfaces as "was
not listed at the merge base", a diagnostic naming the destination and never the typo; and
--update, which rewrites the ledger wholesale, now carries surviving annotations through(the writer is split out as
render_ledgerso the round trip can be asserted).Tests
--self-testgrows 12 assertions. Proven to fail without the fix by running the newtest body against the pre-fix functions restored verbatim:
"Fails against the old code" only proves the feature exists, not that it is safe. So
each anti-laundering case was also checked against the three plausible wrong
implementations of this feature — and each is caught:
The laundering case deliberately holds the total flat, so the total rule cannot be what
fires — it must be the per-path credit, or the hole reopens the day the totals differ.
The undeclared move is still rejected by its own case, so relocation support cannot be
the per-path rule quietly being deleted.
End-to-end on the real ledger, replaying this issue's own split:
Verification
--updateon the real tree is a verified no-op (ledger byte-identical, header preserved).No ceiling was edited. The only change to
scripts/raw_handle_debt_files.txtis 15header comment lines documenting the new form;
git diff | grep -E "^[+-][0-9]"on thatfile returns nothing.
