The nested compilation of `Exporter::Heavy.pm` encountered its + own `use` statements; each one ran + `wasFilterInstalled()` which **returned `true`** (Spiffy's flag, + set just earlier) and triggered + `applySourceFilterToRemainingTokens()` against + `Exporter::Heavy.pm`'s source. +4. Spiffy's filter — which injects `my $self = shift;` after every + `sub …{` — rewrote `Exporter::Heavy.pm` (visible as the warning + `"my" variable $self masks earlier declaration … at + Exporter/Heavy.pm line 237`). `clearFilters()` then emptied the + stack. +5. Control returned to parsing `Test::Base.pm` at the next token + after `use Spiffy -Base;`.

Wiring there would seem more +"thorough", but it has a subtle problem: + +`preprocessWithBeginFilters` deliberately runs a +`BEGIN { filter_add(...) }` prefix through `executePerlCode` **so +that the filter installed inside the BEGIN survives back to the +caller** and can be applied to the parent file's remaining source. +A save/reset/restore wrapper around `executePerlCode` would undo +that install before `applyFilters()` could use it — the recursive +test `perl5_t/t/op/incfilter.t` then regresses from 143/153 to +14/153 (file-handle / coderef source filters from `@INC` break). + +Working around that with a one-shot "skip save/restore" flag +threaded through `preprocessWithBeginFilters` works, but it's +ad-hoc. + +`do_file`'s placement is cleaner: it sits *outside* +`executePerlCode`, so `preprocessWithBeginFilters`' recursive +`executePerlCode` call (which doesn't go through `do_file`) is +naturally unaffected. Per-compilation-unit scoping for the +require/do path is exactly what we need to fix the Spiffy bug, and +nothing more. + +`eval STRING` is **not** wrapped — but the filter chain installed +by an outer `use Foo` is applied to the parent file's remaining +*source tokens* before any `eval STRING` runs at runtime, so an +unprotected eval cannot leak into or out of an enclosing parse +in any way that causes the Spiffy class of bug. + +### Regression test + +`src/test/resources/unit/source_filter_scope.t` reproduces the +exact bug pattern (without depending on any external CPAN module): + +- defines an inline `InlineFilter` package whose `import()` calls + `filter_add` and *then* `require`s `Cwd` (mimicking what + `Spiffy::import` does — `filter_add` followed by + `Exporter::export -> require Exporter::Heavy`), +- asserts that the filter is correctly applied to the + *parent* file's remaining tokens (test 2), +- asserts that `Cwd` itself was unaffected by the filter + (test 3 — `Cwd::cwd()` works), +- asserts the filter doesn't leak past the eval STRING (test 4). + +Confirmed catches the bug: with `saveAndResetFilterState` / +`restoreFilterState` neutralised to no-ops, test 2 fails with +`got: 'REPLACEME', expected: 'ok_marker'` (the filter was consumed +by `Cwd`'s parsing instead of reaching the parent's source). + +--- + +## Phase 7 — `do CODEREF` and `__FILE__` for filehandle/coderef do (2026-04-28) + +Two related issues surfaced while bringing +`perl5_t/t/op/incfilter.t` past the Spiffy regression. Both lived +in `ModuleOperators.do_file`'s source-generator paths. + +### Bug A — STORE called on user's tied `$_` + +The `do CODEREF` generator loop did: + +```java +GlobalVariable.getGlobalVariable("main::_").set(""); // clear $_ +RuntimeBase result = codeRef.apply(stateArgs, ...); // call generator +String chunk = GlobalVariable.getGlobalVariable("main::_").toString(); +``` + +When the user's generator tied `$_` to an object with only +`TIESCALAR` and `FETCH` (no `STORE`) — exactly the pattern in +`incfilter.t` lines 261-268 — the *next* iteration's `.set("")` +invoked the missing `STORE` and died with +`Can't locate object method "STORE" via package "main"`. + +Real Perl handles this with `local $_` in `pp_require`: each +iteration gets its own fresh, untied `$_`; the caller's tied `$_` +is restored at end without ever being written. + +#### Fix + +```java +// Each iteration: install a fresh untied scalar. +GlobalVariable.aliasGlobalVariable("main::_", new RuntimeScalar("")); +... +// At end (in finally): restore the caller's slot WITHOUT calling .set() +GlobalVariable.aliasGlobalVariable("main::_", savedDefaultVar); +``` + +`aliasGlobalVariable` swaps the slot's `RuntimeScalar` reference, +matching `local $_`'s semantics exactly. No `STORE` is ever +invoked on the user's scalar. + +### Bug B — `__FILE__` NPE inside `do FILEHANDLE` / `do CODEREF` + +`actualFileName` was only set in the `do \$scalarref` branch. The +filehandle and code-ref branches left `parsedArgs.fileName = null`, +so `__FILE__` produced a `StringNode` with null `value` and +crashed downstream with +`Cannot invoke "String.length()" because "node.value" is null`. + +#### Fix + +Set `actualFileName = fileName` (the stringified `GLOB(0x…)` / +`CODE(0x…)`) in both branches. Matches the regex assertion in +`incfilter.t`: + +```perl +like(__FILE__, qr/(?:GLOB|CODE)\(0x[0-9a-f]+\)/, "__FILE__ is valid"); +``` + +### Effect on `op/incfilter.t` + +| state | result | +|---|---| +| master (before any of this work) | 143/153 | +| with Phase 6 fix only (Spiffy unblocked) | 143/153 (regressed to 14/153, recovered with `skipSaveRestore` carve-out) | +| with Phase 6 + Phase 7 fixes | **148/153** | + +--- + +## Known Residual: `op/incfilter.t` 148/153 + +Five `cmp_ok` calls expected by the script's hard-coded +`plan(tests => 153)` never fire on PerlOnJava. All 148 that *do* +fire pass; there are zero `not ok` lines. + +### Why the count varies + +Most of the test count comes from `cmp_ok` calls inside two filter +generators that run **once per byte read**: + +```perl +# from prepend_block_counting_filter (lines 148-165) +while (--$count) { + $_ = ''; + my $status = filter_read($amount); # read 1 byte + cmp_ok (length $_, '<=', $amount, "block mode works?"); # ← per byte + $output .= $_; + if ($status <= 0 or /\n/s) { ...; return $status; } +} +``` + +So the total `ok` count = +(bytes through filter 1) + (bytes through filter 2) + +(line count in filter 3) + fixed assertions. Real Perl's byte +stream through these filters is **5 bytes longer** than ours → +5 fewer `cmp_ok` invocations. + +### Where the bytes go missing + +Counting label-by-label: + +| Label | PerlOnJava | Real Perl 5.42 | +|------------------------------------------------|------------|----------------| +| `block mode works?` (43 + 51) | **94** | ~99 | +| `1 line at most?` | 8 | 8 | +| `You should see this line thrice` | 3 | 3 | +| `Upstream didn't alter existing data` | 4 | 4 | +| Fixed `pass` / `is` / `like` / etc. | 39 | 39 | +| **Total** | **148** | **153** | + +Two structural mismatches account for the missing 5 bytes in the +second `prepend_block_counting_filter` invocation (the +`s/s/ss/g; s/([\nS])/$1$1$1/g; return;` array-form filter chain): + +1. **Where `preprocessWithBeginFilters` splits the source.** + PerlOnJava cuts at the closing `}` of `BEGIN { … }` via a + literal brace-match. Real Perl's tokenizer position when the + BEGIN runs is *just past the `;`* terminating the BEGIN + statement — Perl's filter sees those few extra characters that + PerlOnJava had already consumed before reaching the filter + machinery. + +2. **EOF read on the trailing newline.** PerlOnJava's block-mode + `filter_read(1)` returns the trailing newline and then + immediately `0` on the next call; real Perl produces one more + 0-length read at end-of-source before returning EOF. That's a + +1 `cmp_ok` per filter invocation × 2 invocations = +2. + +The `1` from #1 plus `2` from #2 plus minor `\r\n` vs `\n` framing +in the second invocation accounts for the missing 5. + +### Why this isn't worth chasing + +- **Zero `not ok`**: every `cmp_ok` that ran passed. Nothing is + incorrect — only the *count of bytes reported* differs. +- The plan number 153 is a hard-coded count tied to one Perl + implementation's filter byte-stream framing. Anything that + intercepts `filter_read` differently (PerlOnJava, miniperl, + alternative implementations) will produce a different count. +- Aligning to exactly 153 requires either + - reworking `preprocessWithBeginFilters` to find the tokenizer + position the way Perl's lexer does instead of brace-matching + (invasive — would re-tokenize the BEGIN prefix to know where + the `;` is), or + - emitting a synthetic 0-byte `filter_read` cycle at EOF so the + user filter can run one final `cmp_ok` before status=0 + (changes `applyFilters` semantics for every filter). + + Both are big changes for cosmetic test-count parity. Current + state — 148/153, 0 failures — is the right place to leave it. + +### What would actually improve correctness + +If we ever invest in this area further, the meaningful work is: + +1. **Make `filter_read` truly streaming**, not a "split on `\n` then + replay" emulation. Current implementation + (`FilterUtilCall.filter_read`) splits the upstream source on + `(?<=\n)` ahead of time and replays line-by-line; in block mode + it concatenates lines until the requested byte count is hit. + Filters that depend on partial-line state observe slightly + different framing than real Perl. +2. **Drive the filter from the lexer**, one chunk at a time, instead + of `applyFilters(entire-remaining-source)` followed by re-tokenize. + This matches Perl's `PL_rsfp_filters` model and removes the + "rejoin tokens, filter, re-tokenize" round-trip. + +Neither is needed for any currently-failing real-world module — +included here as a roadmap, not a TODO. + +### Files + +- `src/main/java/org/perlonjava/runtime/perlmodule/FilterUtilCall.java` + (Phase 6 `FilterStateSnapshot` + `saveAndResetFilterState` / `restoreFilterState`) +- `src/main/java/org/perlonjava/runtime/operators/ModuleOperators.java` + (Phase 6 try/finally wrapper around the require/do compile + + Phase 7 `local $_` semantics + `__FILE__` for `do FH` / `do CODE`) +- `src/test/resources/unit/source_filter_scope.t` + (Phase 6 regression test) +- `src/test/resources/module/YAML/t/` + (34 upstream YAML-1.31 tests unblocked by Phase 6) diff --git a/dev/modules/yaml_any_fixes.md b/dev/modules/yaml_any_fixes.md new file mode 100644 index 000000000..3a738a7bc --- /dev/null +++ b/dev/modules/yaml_any_fixes.md @@ -0,0 +1,691 @@ +# `jcpan -t YAML::Any` — Investigation and Fix Plan + +## Summary + +`jcpan -t YAML::Any` (i.e. `make test` for the `YAML-1.31` distribution) fails +on PerlOnJava in two distinct ways: + +1. **Source-filter leak** — a `Filter::Util::Call` filter installed by + `use Spiffy -Base;` inside `Test::Base.pm` is consumed by a *nested* + `require Exporter::Heavy` instead of being applied to the rest of + `Test::Base.pm`.

After save/restore is in place, clearing only +affects the current (parent) frame, never the caller's frame. + +### Does the fix behave exactly like system Perl? + +For the cases that matter for `jcpan -t`, **yes**: + +- **Filter scoped to outer file.** Spiffy's filter is applied to the + rest of `Test::Base.pm` only, never to `Exporter::Heavy.pm`. ✓ +- **Nested file gets a clean chain.** A `require`d file may install + its own filters (e.g. its own `BEGIN { … filter_add … }`), and + those apply only to its own remaining source. ✓ +- **Outer file's filter survives the nested load.** When control + returns from `require Exporter::Heavy`, the parent's filter is + still active, so the next `wasFilterInstalled()` check fires + correctly. ✓ +- **`BEGIN { … filter_add … }`-style filters** (handled by + `preprocessWithBeginFilters`) keep working: that path also goes + through `executePerlCode` for the synthetic compile, so its filter + installation is scoped to that synthetic compile and doesn't leak. + ✓ + +Known small differences from real Perl that the fix does **not** +change (and that don't matter for YAML::Any): + +- PerlOnJava applies the filter once to the entire remaining token + buffer (rejoin → filter → re-tokenize), whereas real Perl drives + the filter line-by-line through the lexer. Filters that depend on + fine-grained interaction with the lexer (very rare; Spiffy doesn't) + still behave differently. This is a pre-existing limitation + documented in `FilterUtilCall.java`. +- `__DATA__` / `__END__` handling is approximated by a regex in + `applyFilters`; real Perl just stops feeding the filter at the + end-of-source marker. Adequate for Spiffy/Switch/Filter::Simple. + +The save/restore fix is independent of those limitations and matches +real Perl on the property "a source filter installed by `use Foo;` +applies to the file containing that `use`, and only to that file". + +### Test plan + +1. Add a regression test under `src/test/resources/unit/` + that mirrors the minimal repro — `package Foo; use Spiffy -Base; field _filters => [qw(a b)]; ...` — and asserts it compiles + and runs. +2. `make test-bundled-modules` (covers anything that already exercises + `Filter::Util::Call`, e.g. `Switch`). +3. Re-run `jcpan -t YAML::Any`. Expectation: every `t/*.t` that + currently dies with `syntax error at .../Test/Base.pm line 53, + near "=> [qw"` now reaches its real test body. Pre-existing YAML + semantic failures (Bug 2, below) remain. +4. Spot-check that no previously-passing module regresses: + - `make` (full unit-test run). + - `jcpan -t Switch` if available — Switch is the canonical + `Filter::Util::Call` user. + +### Risks / open questions + +- **Outer-`use` Spiffy filter when the file has *no* further code.** + Trivial — `applySourceFilterToRemainingTokens` is a no-op on an + empty buffer. +- **`eval STRING` inside a filtered file.** After the fix, the eval + starts with an empty filter chain (just like real Perl, where the + string-eval gets its own compilation unit and inherits no source + filter from the surrounding file). This is the correct behaviour + but it's a small change for any caller that currently happens to + inherit a leaked filter. None known. +- **Threading.** `filterContext` and `filterInstalledDuringUse` are + already `ThreadLocal`, so the save/restore is per-thread. Fine. + +--- + +## Bug 2: `YAML.pm` semantics differ from upstream YAML 1.31 + +### What's actually bundled + +There is **no** Perl `YAML.pm` shipped that mirrors the real +`YAML-1.31` distribution.

Only the `YAML::*` +entry points get the compat layer. + +#### Why post-process instead of changing `YAMLPP.java`? + +- `YAML::PP` on real Perl already emits `null` and JSON-style + booleans — it's the YAML 1.2 schema, not a PerlOnJava bug. Modules + that explicitly use `YAML::PP` expect that. +- Adding a "YAML.pm compat" mode to the Java side would either: + (a) require a new schema in `YAMLPP.java`, ~50 lines of + resolver/representer plumbing, or + (b) add a per-instance flag that the load/dump paths inspect — a + pile of conditional code in hot paths. + Doing it in the 12-line Perl shim keeps the fix in **one** file + and 100 % out of the JVM hot path. +- The compat layer is the kind of thing real `YAML::Any` does too + when it picks a backend. + +### Does this fix match real YAML.pm 1.31 semantics? + +For `t/2-scalars.t` and the typical `use YAML;` consumer, **yes**: + +- `Dump(undef)` → `--- ~\n` ✓ +- `Load("--- ~\n")`, `Load("---\n")`, `Load("--- ''\n")` already work ✓ +- `Load("--- true\n")`, `Load("--- false\n")` → strings `"true"`/`"false"` ✓ +- malformed quoted strings → die with `Can't parse single`/`Can't parse double` ✓ +- numbers, strings, refs, hashes, arrays — unchanged from current + (already passing) behaviour ✓ + +Caveats not addressed by this fix (and not exercised by the test +suite): + +- YAML.pm 1.x emits some scalar-styling decisions (line wrapping + thresholds, when to single-quote vs plain) that YAML::PP differs + on. Out of scope; nothing in `t/2-scalars.t` tests it. +- YAML.pm 1.x has its own anchor/alias numbering scheme (`&1`, `*1`) + whereas YAML::PP uses `&a001`. Already different, no regression. +- Other YAML modules that depend on YAML.pm's error message text + (e.g. `YAML::Tiny`-derived test suites) may need similar + translations; address case-by-case. + +--- + +## Path to making **all** YAML-1.31 tests pass + +The fixes above unblock `t/2-scalars.t` and the ~14 test files that +currently die with `Compilation failed in require` because of the +Spiffy filter leak. Getting **every** one of the 54 `t/*.t` files +green is a different conversation: the test suite was written against +one specific Perl implementation (`YAML.pm` 1.x) and probes its +*exact* output, error text, anchor numbering, blessing protocol, +B::Deparse code dumping, etc. PerlOnJava ships a YAML 1.2 engine +under that name, so a small wrapper can never satisfy all of +those tests. + +Realistically, three approaches scale to "all tests pass": + +### Approach A — install the *real* `YAML.pm` from CPAN (recommended) + +`YAML-1.31` is **pure Perl** (only deps: `YAML::Mo` — bundled with +the dist — `Scalar::Util`, `B`). No XS. Its tests are written to +exercise its own implementation. The clean path is: + +1. Land the **Spiffy filter-leak fix** (Bug 1) so `Test::Base.pm` + compiles. Without this, no YAML test even starts. +2. **Stop bundling `YAML.pm`** as an unconditional shim. Two + sub-options: + - **A1.** Remove `src/main/perl/lib/YAML.pm` from the JAR + entirely. Users who want `Load`/`Dump` either `use YAML::PP;` + (Java-backed, works) or run `cpan YAML` (real Perl, works). + - **A2.** Keep the shim as a *fallback*: change the + `MakeMaker.pm` SKIP logic at line 357 to allow `YAML.pm`, + `YAML/Loader*.pm`, `YAML/Dumper*.pm`, `YAML/Mo.pm`, etc. to be + overwritten by the CPAN version. A1 is cleaner; A2 keeps the + "out of the box `use YAML;` works" property. +3. Run `jcpan -t YAML`. Tests now run against real `YAML.pm` 1.31. +4. Triage the residual failures. Real `YAML.pm` exercises a fair + amount of Perl machinery that can hit PerlOnJava limitations: + - `B::Deparse` (for `Dump` of code refs — `dump-code.t`, + `load-code.t`) + - Glob serialisation (`dump-blessed-glob.t`) + - Tied hashes / iterating restored objects + (`pugs-objects.t`, `marshall.t`) + - `${\ \my $x}` style refs of refs, `weaken`-tracked cycles + (`references.t`, `bugs-rt.t`) + - Regex stringification for `qr//` (`regexp.t`) + - Numification edge cases (`numify.t`, `dump-stringy-numbers.t`) + - `local $/` slurp + UTF-8 BOM handling + (`dump-file-utf8.t`, `io-handle.t`) + - Symbol-table magic in `YAML::Mo` (`*{$M.'Object::new'} = sub{...}`, + `${$P.':E'}`, etc.) +5. Each residual failure becomes one of: + - a real PerlOnJava bug (fix it — likely small per failure), + - an unsupportable feature (e.g. `DESTROY`-based teardown in a + test — skip with `SKIP` block, document in this file), + - a YAML.pm bug already known upstream (skip). + +Cost: medium. Most fixes are one-liners or small parser/runtime +patches. Reward: future YAML.pm-derived tests "just work". + +### Approach B — make `YAML::PP` faithful to YAML.pm 1.x in the shim + +Extend the YAML.pm shim (the strategy in this document so far) to +cover **everything** the test suite checks, not just the 5 mismatches +in `t/2-scalars.t`. In practice that means re-implementing +YAML.pm's output format on top of `YAML::PP`'s parser/emitter: + +- A custom Dumper that emits `~`, plain `true`/`false`, + YAML.pm-style anchors `&1`/`*1`, YAML.pm's quoting heuristics + (when to single-quote, when to fold), YAML.pm's `Indent`/`UseHeader`/ + `UseAliases`/`UseBlock`/`UseFold`/`SortKeys` semantics. +- A custom Loader that respects `$YAML::LoadCode`, + `$YAML::LoadBlessed`, the "perl/code", "perl/glob", "perl/regexp", + "perl/hash:Class" tag families used by `Marshall`/`Bless`. +- Error-message translation table for every snakeyaml exception that + the test suite pattern-matches (`load-fails.t`, `errors.t`). +- B::Deparse-based code-ref serialisation for `dump-code.t`. +- `YAML::Node`/`YAML::Tag` shims so tests that introspect node info + (`node-info.t`, `preserve.t`) see the right object structure. + +Cost: high. Probably 1000–2000 lines of compatibility Perl plus +non-trivial Java work in `YAMLPP.java` (custom representer/resolver +chains, listener for raw-token style preservation). Reward: a +single self-contained shim with no CPAN bootstrap dependency. +Downside: every future YAML.pm release re-creates the diff. + +### Approach C — port real `YAML.pm` 1.31 into the bundled JAR + +Replace the 12-line shim with the actual `YAML.pm` / `YAML/Loader.pm` +/ `YAML/Dumper.pm` / `YAML/Mo.pm` / `YAML/Marshall.pm` / +`YAML/Node.pm` / `YAML/Types.pm` / `YAML/Error.pm` / `YAML/Tag.pm` +files, vendored under `src/main/perl/lib/`. Do NOT load `YAML::PP` +from `YAML`. + +Same end state as A but the user doesn't need to run `cpan YAML` to +get YAML.pm semantics. Mechanics are identical to A from then on — +the same residual triage list, the same per-failure PerlOnJava bug +fixes. + +Cost: low to vendor + same triage work as A. Reward: matches +upstream out of the box. Risk: one more pure-Perl module that we +re-sync on each upstream release. + +### Recommendation + +Approach **A2** (or **C**, which is materially the same thing +delivered as a vendor copy). Concrete sequence: + +1. **Land the source-filter save/restore fix** in + `PerlLanguageProvider.executePerlCode`. This alone unblocks the + bulk of the suite. +2. **Whitelist** the YAML distribution's `.pm` files in + `MakeMaker.pm`'s SKIP logic so `cpan YAML` can install over the + shim. Or vendor real `YAML.pm` (Approach C). +3. **Run** `jcpan -t YAML` and capture the new failure set in this + document. Each remaining failure becomes its own bullet here + plus, where applicable, a small ticket / PR. +4. **Stop using the wrapper for tests.** When PerlOnJava sees a + distribution whose own name is `YAML`, it should use the + user-installed real `YAML.pm`, not the bundled shim — the test + harness should test what's about to be released, not what + PerlOnJava ships. + +Approach B is reserved for the case where bootstrapping CPAN-`YAML` +is itself a hard problem. Today it isn't: `cpan YAML` works on +PerlOnJava once Bug 1 is fixed (its only real dependency is its own +`YAML::Mo`, vendored inside the dist). + +### What "all tests pass" probably looks like in practice + +After steps 1–3 above, an honest expectation is: + +| outcome | rough % of files | what to do | +|---|---|---| +| pass cleanly | ~60–75% | nothing | +| pass after a small PerlOnJava fix | ~15–25% | file as targeted bugs (regex/B::Deparse/etc.) | +| skip because of `fork`/`threads`/DESTROY | ~5% | `SKIP` block, document | +| genuine YAML.pm-1.x quirks too costly to match | <5% | document as known mismatch | + +There is no single PR that lands "all YAML tests pass". But there +is a well-defined sequence — Spiffy fix → switch to real YAML.pm → +triage residue — that converges on it. + +--- + +## Suggested order of work + +1. **Fix Bug 1** (source-filter save/restore in `executePerlCode`). + This is the high-leverage change: it unblocks YAML::Any, all of + `Switch`, all of `Filter::Simple`, and any future `Spiffy`-based + module — for a ~30-line change in one file. +2. Re-run `jcpan -t YAML::Any` and record the new pass/fail set. +3. **Pick an option for Bug 2** based on what's still failing after + step 2 and how much real YAML.pm-1.31 PerlOnJava can tolerate. +4. Add a unit-test regression test under `src/test/resources/unit/` + for the Spiffy/source-filter scenario so this exact failure mode + can't silently come back. + +## References + +- `src/main/java/org/perlonjava/runtime/perlmodule/FilterUtilCall.java` +- `src/main/java/org/perlonjava/frontend/parser/StatementParser.java` + (`applySourceFilterToRemainingTokens`, ~line 1290) +- `src/main/java/org/perlonjava/app/scriptengine/PerlLanguageProvider.java` + (`executePerlCode`, ~line 71) +- `src/main/java/org/perlonjava/runtime/perlmodule/YAMLPP.java` +- `src/main/perl/lib/YAML.pm` +- `~/.cpan/build/Net-IPv4Addr-0.10-1` — unrelated, but the previous + `jcpan -t Net::IPv4Addr` investigation lives in the session log. + +## Progress Tracking + +### Current Status: Bug 1 + Bug 2 fixed; long-tail residue remains + +### Completed Phases + +- [x] **Bug 1 — source-filter state save/restore** (2026-04-28) + - Added `FilterUtilCall.saveAndReset()` / `restore(FilterState)` + so the per-thread filter stack and the `filterInstalledDuringUse` + flag are scoped to a compilation unit instead of leaking across + nested `require`/`do FILE`/string-`eval`. + - Wired into `PerlLanguageProvider.executePerlCode` via an outer + `try { … } finally { FilterUtilCall.restore(savedFilterState); }`. + - Regression test: `src/test/resources/unit/source_filter_scope.t` + (Spiffy `field …` minimal repro + `use Test::Base` smoke test). + - Effect on the YAML-1.31 distribution: 27 of the 35 previously + blocked test files now pass cleanly.
