feat(coverage): read jacoco xml reports natively by newhoggy · Pull Request #2197 · rust-works/omni-dev

newhoggy · 2026-10-05T10:38:44Z

Description

JaCoCo reports from Java, Kotlin and Scala can now be read directly by coverage diff, coverage merge and the MCP coverage_diff tool. XML detection distinguishes JaCoCo's <report> root from Cobertura's <coverage> root; --report-format jacoco also works explicitly, including for baselines.

A partially covered line (mi > 0, ci > 0) counts as covered. Instruction counts become boolean hits, and aggregate groups or separate module reports merge by covered-line union. Branch counters and class/method summaries are ignored.

Implementation plan

Changes Made

Add src/coverage/jacoco.rs with sourcefile/line parsing, default-package support, escaped names, group aggregation and malformed-input validation.
Add Format::Jacoco and XML-root detection after declarations, comments and DTDs in src/coverage/format.rs; retain the existing Cobertura parser.
Expose jacoco in CLI and MCP selectors and update the reviewed help snapshot.
Document line semantics and source-root path limitations in docs/coverage.md; add an [Unreleased] changelog entry.
Add parser/detection regressions, CLI merge/diff tests and an MCP protocol test using both auto and explicit detection.

Testing

All commands ran in /Users/jky/wrk/work-trees/omni-dev/issue-2187-jacoco-xml, with Cargo explicitly targeting that worktree's manifest. Checks were rerun after the review fix and rebase.

WT=/Users/jky/wrk/work-trees/omni-dev/issue-2187-jacoco-xml
cargo build --manifest-path "$WT/Cargo.toml"
cargo fmt --manifest-path "$WT/Cargo.toml" --all -- --check
cargo clippy --manifest-path "$WT/Cargo.toml" --all-targets --all-features -- -D warnings

omni-dev git commit message lint origin/main..HEAD

Results: build, formatting, Clippy, marker lint, changelog and commit lint all passed. The final default suite passed 13,468 tests and the MCP suite passed 14,367 tests, with zero failures and one existing ignored test in each. The full suites cover the help snapshot. JaCoCo tests exercise multiple packages, partially covered lines, default packages, escaped attributes, aggregate groups, module/shard union, malformed or truncated XML, missing/invalid numbers, stray text outside the root and MCP gate results. Coverage percentages were not measured locally; CI computes them. No live JVM report-generation test was run.

The first sandboxed filtered test run could not bind local Wiremock ports; both full suites were rerun with that access enabled. Apple’s linker emitted a large __eh_frame warning for a test binary; tests passed and Clippy reported no lint warnings.

Review Focus Areas

Paths remain source-root-relative (com/example/App.java), which may differ from git paths such as src/main/java/com/example/App.java.
Identical package/file paths across modules merge; unrelated sources sharing that path require disambiguation before merging.
XML-root detection now rejects unknown roots instead of treating every XML document as Cobertura.

Checklist

Followed project style and commit guidelines
Reviewed the committed diff against origin/main...HEAD
Added documentation and regression tests
Reviewed and accepted the intended CLI help snapshot changes
Rebased onto refreshed origin/main

Performance Impact

Streaming XML parsing with memory proportional to coverage records and XML nesting. No JVM or converter process is invoked.

Security Considerations

External DTDs/entities are not fetched. Invalid numeric attributes and malformed/truncated documents return errors.

Deployment Notes

No special deployment requirements. Rust callers exhaustively matching the public Format enum must handle the added variant.

Additional Notes

One review finding at src/coverage/jacoco.rs's event loop was fixed in a separate commit: stray text/CDATA outside the root could be accepted. Added a regression test; no findings were skipped. No departure from the plan.

Source-root mapping remains the existing #2188 follow-up. This PR preserves paths rather than guessing Maven/Gradle layouts. Clover and branch coverage remain out of scope.

Parse sourcefile line records and detect XML by its root element so JVM coverage reports need no Cobertura converter. Expose jacoco in CLI and MCP selectors and test partial coverage, aggregate groups and shards. Preserve source-root-relative paths and document the mapping limitation tracked in #2188. Closes #2187

Reject stray text and CDATA before or after the root so malformed XML cannot silently produce an apparently valid coverage report. Add a regression test while preserving whitespace and trailing comments.

File	Kind	Lines	Rev	Reason
`src/claude/client.rs`	`ignore`	815-827	both	process-bound: hardcodes SystemEnv with no injectable seam (unlike create_default_claude_client_with's tested Default arm, which this mirrors) and has no in-crate caller; testing it would mean mutating real process env for shared credential vars
`src/cli/ai/jev/route.rs`	`ignore`	176-251	both	RouteCommand::execute is the process-bound wiring shell; fetch_docs, run_route_with_reference_fetch_failures, render_output_with_style and terminal_style_with provide its deterministic seams
`src/cli/ai/jev/route.rs`	`ignore`	325-330	both	the SystemEnv/stdout probe is process-bound; terminal_style_with is exhaustively covered through its injected environment and TTY seam
`src/cli/ai/jev/route.rs`	`ignore`	882	both	guards this test's assumption; the parse above always fails on --ignore-closed with --allow-closed
`src/cli/ai/jev/route.rs`	`ignore`	914	both	guards this test's assumption; the parse above always fails on a malformed --ladder-definition
`src/cli/ai/jev/verify_decision.rs`	`ignore`	89-142	both	VerifyDecisionCommand::execute is the process-bound wiring shell; fetch_input and run_verify provide its deterministic seams
`src/cli/claude_wrap.rs`	`ignore`	160-170	both	process-bound wiring shell: it joins this process's own stdin/stdout and reads the real OMNI_DEV_CLAUDE_WRAP_LOG, which a test must not take over (see the note on run/wrap in the tests module); wrap_io_diagnostics beneath it is covered directly
`src/cli/claude_wrap.rs`	`ignore`	716-720	both	resolve_socket fails only when the platform has no data directory to put the default socket in (no resolvable home), which a test cannot reproduce on macOS or Linux; the fail-open return is what keeps the wrapper forwarding
`src/cli/claude_wrap.rs`	`ignore`	773-777	both	to_value on an ObserveRequest fails only for a non-UTF-8 cwd, and the tracker takes cwd from a JSON string, so it is always UTF-8; the arm exists so a future non-string field cannot silently drop the report
`src/cli/claude_wrap/diagnostics.rs`	`ignore`	60	both	Builder::spawn fails only when the OS refuses a new thread (resource exhaustion), which a test cannot provoke; the fail-open return is what keeps the wrapper forwarding
`src/cli/drive.rs`	`ignore`	2407	both	guards this test's assumption; the parse above always yields DriveSubcommands::Sync for a sync argv
`src/cli/drive/lease.rs`	`ignore`	564-568	both	a sheet restore's fresh backup is always a DriveCopy — restore.rs's own recheck refuses unless the target is still a spreadsheet, and acquire() only ever takes a Bytes backup of a non-native target; this arm exists solely for exhaustiveness over the shared LeaseBackup enum
`src/cli/drive/lease.rs`	`ignore`	1274-1277	both	guards this test helper against misuse; every call site below passes an acquire subcommand
`src/cli/drive/lease.rs`	`ignore`	1288-1291	both	guards this test helper against misuse; every call site below passes a prune subcommand
`src/cli/drive/sheets/values.rs`	`ignore`	208	both	this closing brace of the `if let Some(...) = last` (no else) reports 0 hits under llvm-cov even though both inner branches are exercised (csv_interior_blank_line_before_an_unterminated_last_row_is_kept hits the insert path, csv_single_trailing_newline_adds_no_row hits the no-insert path); `last` is always `Some` once `missing_final_newline` is true, since the loop above always runs at least once for non-empty content, so there is no reachable skip path — the same llvm-cov region-attribution artifact on an if-let's closing brace as src/utils/settings.rs:1096
`src/cli/drive/trash.rs`	`ignore`	168	both	guards this test's assumption; the parse above always yields a trash or untrash subcommand
`src/cli/gmail/draft/create.rs`	`ignore`	2088-2092	both	never called: every test using UnreadableStdin gives an HTML body, so resolve_body returns before reading stdin; the panic exists to fail loudly if that ever changes
`src/cli/gmail/draft/update.rs`	`ignore`	261	both	this closing brace reports 0 hits under llvm-cov regardless of test count — verified locally: run_update_sets_a_checked_from_and_keeps_everything_else and run_update_to_the_nameless_primary_leaves_from_to_gmail both complete the block above successfully (proven by the outer if-let's own closing brace and the following let drafts = ... line both measuring as hit), yet this specific inner brace, immediately after a statement with two chained ? operators, never registers a hit; an llvm-cov region-attribution artifact, not an untested path
`src/cli/gmail/sync_all.rs`	`ignore`	213-246	both	SyncAllCommand::execute is the process-bound wiring shell: it loads the real ~/.omni-dev settings and builds clients against the real Gmail host; run_sync_all, load_gmail_sync_config and validate_accounts are its tested seams
`src/cli/sessions.rs`	`ignore`	273-276	both	resolve_socket fails only when the platform has no data directory to put the default socket in (no resolvable home), which a test cannot reproduce on macOS or Linux; the sink is fail-open by design, so this is the same silent return as every other skipped hook
`src/cli/sessions.rs`	`ignore`	283	both	wire returns None only through the serialization failure ignored in wire() itself (a non-UTF-8 cwd, which a hook payload cannot carry), so this arm is unreachable for the same reason
`src/cli/sessions.rs`	`ignore`	403-410	both	to_value on an ObserveRequest fails only for a non-UTF-8 cwd, and the hook payload's cwd is deserialized from a JSON string, so it is always UTF-8; the arm exists so a future non-string field cannot silently drop the report
`src/cli/sessions.rs`	`ignore`	3529	both	the arm above always matches: parse() above always parses an install-hooks argv into SessionsSubcommands::InstallHooks
`src/cli/sessions.rs`	`ignore`	3533	both	the arm above always matches: parse() above always parses an uninstall-hooks argv into SessionsSubcommands::UninstallHooks
`src/cli/worktrees/ui/terminal/pty.rs`	`ignore`	311-318	both	the closure runs only in the forked child between fork and exec, and exec discards that process's coverage counters before they can be flushed, so llvm-cov reports 0 hits on these lines however often the tests run it (CI measured the whole body uncovered on PR #2169); the reset is checked by behaviour instead, in the_well_behaved_test_passes_when_the_test_process_ignores_sighup
`src/daemon/services/worktrees/divergence.rs`	`ignore`	346	both	only runs if a started computation never sets its flag within 2s, which fails the calling test; a passing run never takes it
`src/drive/docs/anchor.rs`	`ignore`	351	both	map_boundary is only called with a byte offset inside the text its runs concatenate, so the loop always returns first; the Err keeps the function total without a panic
`src/drive/docs/anchor.rs`	`ignore`	404	both	a match never contains the paragraph's closing newline (find rejects a needle with one) and collect verified the last run ends at it, so the index always lies inside the paragraph; kept as defence on the write boundary
`src/drive/docs/anchor.rs`	`ignore`	463	both	a container switch between two paragraphs of one container is always a table, and the paragraph before it has protected_newline, so the check below refuses the range before the walk reaches a foreign paragraph; kept as defence in depth
`src/drive/docs/anchor.rs`	`ignore`	488	both	lo and hi are regex match boundaries mapped through whole runs, so neither falls inside a surrogate pair; kept as defence in the UTF-16 arithmetic
`src/drive/docs/anchor.rs`	`ignore`	496	both	end is the end of the last anchor, which lies inside a run the loop above visits, and a gap before it already returned UnsafeRange, so the cursor always reaches it; kept as defence in depth
`src/drive/docs/anchor.rs`	`ignore`	577	both	collect verified every paragraph has a final run ending at p.end, and the loop above leaves cursor at that run's end, so it always matches; kept as defence in depth on the write boundary
`src/drive/docs/anchor.rs`	`ignore`	648	both	collect refuses a paragraph whose last run does not end at the paragraph's end, and the loop above leaves cursor on the last run's end, so cursor always equals p.end here; kept as defence in depth on the write boundary
`src/drive/docs/named_range.rs`	`ignore`	214	both	the Create branch above always returns, so a Create mutation never reaches the ID lookup; the arm exists solely for exhaustiveness
`src/drive/docs/named_range.rs`	`ignore`	283	both	the Create branch above always returns, so a Create mutation never reaches this match; the arm exists solely for exhaustiveness
`src/drive/docs/table.rs`	`ignore`	329	both	rows, cells and paragraphs are each checked above to start at or after the previous one's end, so the half-open cell ranges are pairwise disjoint and at most one contains the index; kept as defence in depth on the write boundary
`src/drive/docs/table.rs`	`ignore`	349	both	an Insert edit returned from the branch above, so only a Dimension edit reaches here; the else-arm exists only to destructure the already-known variant
`src/drive/docs/table.rs`	`ignore`	386	both	validate already refuses a Dimension edit carrying InsertTable before resolve reads the document, so this arm exists solely for exhaustiveness over TableVerb
`src/drive/docs/write.rs`	`ignore`	942-946	both	`preview` is built by the payload match above, so a Table payload always carries a WouldEditTable preview; this arm exists solely for exhaustiveness over the shared WriteResult enum
`src/drive/docs/write.rs`	`ignore`	960-964	both	`preview` is built by the NamedRange payload match above, so a NamedRange payload always carries WouldMutateNamedRange; this arm exists solely for exhaustiveness over the shared WriteResult enum
`src/drive/docs/write.rs`	`ignore`	991-995	both	`preview` is built by the payload match above, so an Insert/Delete/List payload always carries its matching edit preview; this arm exists solely for exhaustiveness over the shared WriteResult enum
`src/drive/docs/write.rs`	`ignore`	2343	both	anchored_payloads yields only Insert and Delete
`src/drive/lease/ledger.rs`	`ignore`	1109-1113	both	mutate_locked refuses before ever calling the closure, so its body never runs — a hit here is a regression, not a coverage gap
`src/drive/lease/restore.rs`	`ignore`	1261-1265	both	every test using this double refuses before authenticating; a hit here is a regression, not a coverage gap
`src/drive/sheets/api.rs`	`ignore`	1492	both	the assertion arm only fires if the outcome type regresses, in which case the test has already failed
`src/drive/sheets/auto_fill.rs`	`ignore`	584	both	unreachable by construction: source_grid.sheet_id was itself resolved from this same workbook by resolve_grid_range above, so find_sheet_by_id always finds it
`src/drive/sheets/auto_fill.rs`	`ignore`	802	both	every call site resolves grid from a range already checked with grid_range::is_bounded, or computes it from one via compute_destination, which only ever produces a fully bounded range from a fully bounded source; this else-arm exists only to unwrap the shared Option fields
`src/drive/sheets/auto_fill.rs`	`ignore`	815	both	unreachable by construction: compose rejects only a sheet-prefixed or whole-sheet range, and the numeric {start}:{end} built just above is neither
`src/drive/sheets/auto_fill.rs`	`ignore`	1471	both	guards this test's assumption; build_request always returns AutoFill
`src/drive/sheets/auto_fill.rs`	`ignore`	1488	both	guards this test's assumption; build_request always returns AutoFill
`src/drive/sheets/auto_fill.rs`	`ignore`	2688	both	guards this test's assumption; the mocked response above always leads to WouldChange

`src/drive/sheets/cell_format.rs`	`ignore`	294	both	this closing brace reports 0 hits under llvm-cov regardless of test count — verified locally: render_line_covers_background_bold_number_note_and_validation and render_line_covers_italic_strikethrough_underline_foreground_alignment_and_bare_validation both complete the block above (the pattern and no-pattern pushes both measure as hit), yet this specific brace, closing the format_type.is_empty() check, never registers a hit; the same llvm-cov region-attribution artifact as src/utils/settings.rs:1096
`src/drive/sheets/delete_duplicates.rs`	`ignore`	1405	both	this let-else panic only runs if the match failed to bind the expected variant; an open-ended range always refuses here

`src/sessions/watcher.rs`	`ignore`	250-254	both	spawn_blocking's JoinError needs the scan closure to panic or the runtime to shut down mid-scan; scan has no panicking path, and the runtime outlives the watcher, whose token is cancelled first
`src/utils/secret_env.rs`	`ignore`	936-944	both	the loop above runs this 4 times and every mode fails the same way; verified locally that llvm-cov still reports 0 hits on the matches!( line — a region-attribution artifact on the nested assert!/matches! macro call, not an untested path
`src/utils/secret_env.rs`	`ignore`	1366	both	exercised by strip_test_modules_ignores_braces_in_literals_and_comments's '{' char literal; verified locally that llvm-cov still reports 0 hits — a region-attribution artifact on this closing brace, not an untested path
`src/utils/secret_env.rs`	`ignore`	1421	both	only runs if an unregistered secret-shaped literal exists; the assert below that unknown is empty is this test's whole point, so a passing run never takes this branch
`src/utils/secret_env.rs`	`ignore`	1479-1481	both	only runs if a registered secret is read through a plain accessor outside this module; offenders.is_empty() below is this test's whole point
`src/utils/secret_env.rs`	`ignore`	1525	both	only runs if a _FILE companion collides with an existing variable; collisions.is_empty() below is this test's whole point
`src/utils/secret_env.rs`	`ignore`	1556	both	only runs if a stray file names the companion; strays.is_empty() below is this test's whole point
`src/utils/secret_env/command.rs`	`ignore`	281-290	both	try_wait on a live, owned child fails only if waitpid itself errors (ECHILD/EINTR from outside the process); no in-process test can provoke it, and the arm only reaps and reports
`src/utils/settings.rs`	`ignore`	1235	both	this closing brace reports 0 hits under llvm-cov regardless of test count — verified locally: upsert_account_writes_a_secret_into_its_file_not_settings and several other tests complete the block above (the push on the line just before, and entry.remove(*key) right after, both measure as hit), yet this specific brace, immediately after an if-let whose scrutinee ends in a `?` operator, never registers a hit; an llvm-cov region-attribution artifact, not an untested path

fix(coverage): reject text outside the jacoco report root

b5d431f

Reject stray text and CDATA before or after the root so malformed XML cannot silently produce an apparently valid coverage report. Add a regression test while preserving whitespace and trailing comments.
