fix(wren): mark truncated values in the skipped-row report#2675Harry-Sun0529 wants to merge 4 commits into
Conversation
_report_skipped bounded each listed value with {v!r:.120}, which cut
mid-token without a marker, so a fragment was indistinguishable from a
complete value. Extract the cap as _VALUE_REPR_LIMIT and report the full
length alongside the cut.
Also close two test holes raised in the Canner#2570 review: the truncation test
asserted only the derived '... and N more' count, which reads correctly
even when the per-row listing is not capped; and the repr bound was a
loose len(line) < 200 rather than the documented limit.
Closes Canner#2629

Pull request overview
This PR improves the wren utils parse-types / translate-types skipped-row reporting so that truncated corrupt values are clearly marked (and include the full rendered length), and tightens/extends CLI regression tests to prevent previously identified test holes.
Changes:
- Introduces
_VALUE_REPR_LIMITand_format_corrupt_value()to render truncated corrupt values with an explicit marker and total length. - Strengthens the skipped-row truncation test to ensure the per-row listing is actually capped (not just the trailing “... and N more” count).
- Adds/updates CLI tests to assert exact truncated rendering behavior and adds a
translate-typesnon-list string-payload regression test.

Added in 2cd15cf — pinned in one dedicated test (test_value_repr_limit_is_the_documented_cap) rather than hardcoded alongside each expectation, so the rendering tests stay correct at any cap while the value itself can no longer drift unnoticed. Verified both ways: changing the cap to 100 fails that test and nothing else.

Included review availability: Your plan includes up to 10 reviews per rolling hour; 9 remain after this review.
A non-list payload must error cleanly rather than crash, so pin the absence of a traceback alongside the exit code and message. Addresses CodeRabbit review on Canner#2675.
The rendering tests derive their expectations from the constant, which keeps them correct at any cap but lets the value itself change unnoticed. Pin it in one dedicated test instead of hardcoding the number alongside each expectation. Addresses Copilot review on Canner#2675.
What
_report_skipped()bounded each listed value with{v!r:.120}. That caps thelength, but it cuts mid-token and adds no marker, so a fragment is
indistinguishable from a complete value. This extracts the cap as
_VALUE_REPR_LIMITand reports the full length alongside the cut:A value that fits the cap renders exactly as its
repr(), unchanged.Also closes the two test holes raised in the #2570 review:
test_cli_parse_types_skip_report_truncates_past_limitasserted only"... and 2 more", whose count is derived from_SKIP_REPORT_LIMITandtherefore reads correctly even when the per-row listing is never capped.
Added a negative assertion so dropping the slice fails.
test_cli_parse_types_corrupt_value_repr_is_boundedused a looselen(line) < 200; it now asserts the exact rendering against thedocumented limit.
Optional item 3 from the issue is included since it is a one-line addition in
the same file: a
translate-typesnon-list string payload regression,mirroring the existing
parse-typesone.Why
Follow-up to #2570; both items were deliberately deferred in that review so
they wouldn't hold up the fix for #2528.
