Note: items marked **fixed** below are +resolved by the Phase-1 read path that has since landed; the +underlying issue (jperl writes still aren't system-perl-readable) +persists pending Phase 2. + +1. **CPAN.pm `~/.cpan/Metadata` cache.** CPAN persists its module index + with `Storable::nstore`. Before the read path landed, switching + between `perl` and `jperl` always invalidated the cache: + - jperl-written file → system perl: `File is not a perl storable at + .../Storable.pm line 411`. **Still happens** until Phase 2 makes + jperl write `pst0`. + - perl-written file → jperl: used to error with + `retrieve failed: …`. **Fixed** — jperl now decodes upstream + `pst0` files correctly, so reading a system-perl-written cache + no longer triggers a re-index. + +2. **distroprefs / persistent state.** CPAN.pm warns + `'YAML' not installed, will not store persistent state` on system + perl when only YAML metadata is present, then falls back further. + **Still happens** for caches that jperl wrote. + +3. **Other tooling.** Anything that hands a `freeze`d blob to / from a + real perl breaks: `Cache::FileCache`, DBI-cached statement metadata, + `DBM::Deep` Storable values, build-system caches (e.g. ExtUtils + `.packlist` adjacent state, `Module::Build`'s `_build/` Storable + files), Sereal/Storable hybrid pipelines, etc. **Half fixed:** the + real-perl → jperl direction now works; the jperl → real-perl + direction is still broken until Phase 2. + +4. **Cross-process IPC.** `Storable::freeze`/`thaw` is a common wire + format between Perl processes.

Add `org.perlonjava.runtime.perlmodule.storable.NativeReader` (new + package) implementing the file/in-memory header parse (`pst0`, + netorder vs native byte order, version check). +2. Implement opcode dispatch for: SX_UNDEF, SX_BYTE, SX_INTEGER, + SX_NETINT, SX_DOUBLE, SX_SCALAR, SX_LSCALAR, SX_UTF8STR, SX_LUTF8STR, + SX_REF, SX_ARRAY, SX_LARRAY, SX_HASH, SX_LHASH, SX_FLAG_HASH, + SX_BLESS, SX_IX_BLESS, SX_OBJECT, SX_OVERLOAD, SX_TIED_*. Tied + variants throw "tied …" diagnostic by default. +3. Hook (SX_HOOK / SX_HOOK_CLONE) parser that calls existing + STORABLE_thaw plumbing in `Storable.java`. +4. Differential test harness: a small Perl script run under system + `perl` that emits a fixture file, plus a jperl test that retrieves + it and dumps via Data::Dumper. New file: + `src/test/resources/storable/native_decode.t`. + +Exit criterion: `~/.cpan/Metadata` written by system perl is readable +by jperl. (This is the immediate user-visible win — no more re-index.) + +### Phase 2 — Encoder (write upstream Storable) + +Goal: `Storable::store` / `nstore` / `freeze` / `nfreeze` emit bytes +byte-identical to upstream for canonical-mode output. + +Tasks: + +1. `NativeWriter` mirroring `NativeReader`. Write `pst0` header, choose + integer width (SX_BYTE vs SX_INTEGER vs SX_NETINT) the same way XS + does. +2. `$Storable::canonical` honored for hash key ordering. Already + honored on the YAML path; port the test. +3. SX_OBJECT shared-reference table, keyed on identity (Java + `IdentityHashMap`, as the current code already uses). +4. STORABLE_freeze hook emission. +5. Differential round-trip test: jperl-encoded → system-perl-decoded + for the same fixture set used in Phase 1. + +Exit criterion: jperl-written `~/.cpan/Metadata` is readable by system +perl. Bidirectional CPAN cache sharing works. + +### Phase 3 — Cutover and YAML deprecation + +1. Default `store`/`retrieve`/`freeze`/`thaw` to native binary. +2. Keep the existing YAML reader as a fallback for files that don't + start with `pst0` (so users with old jperl-written caches don't + silently lose them on upgrade). Log a one-time warning and + recommend regeneration. +3. Drop the YAML writer path. Remove the `BINARY_MAGIC = '\u00FF'` + in-memory format and migrate `freeze`/`thaw` to the netorder body + layout instead — this is what real `Storable::freeze` returns and + what other Perl code expects on the wire. +4. Update `dev/modules/cpan_client.md` and the AGENTS table for + `Storable`. + +### Phase 4 — Optional follow-ups + +- `Storable::file_magic` (used by some tooling to sniff files). +- `Storable::read_magic` on an open filehandle. +- `$Storable::Deparse` / `$Storable::Eval` for code refs (currently + refused; bring up to parity with upstream's documented behavior of + emitting `B::Deparse` text and re-`eval`-ing on retrieve). +- Sereal-style `freeze`/`thaw` interop is **not** in scope — that's a + separate module. + +## Risks and open questions + +1. **Hash-key ordering.** Upstream Storable's non-canonical mode emits + keys in Perl's iteration order, which is randomized. We currently + iterate Java `LinkedHashMap`s in insertion order. For non-canonical + output we should match Perl's behavior closely enough that + round-trip equality holds — ordering doesn't have to match exactly, + but tests that compare frozen byte streams across perls must use + `$Storable::canonical = 1`. Document this in the module POD. +2. **Numeric type promotion.** Perl picks SX_BYTE / SX_INTEGER / + SX_NETINT / SX_DOUBLE based on the SV's flags (IOK, NOK, POK). + PerlOnJava `RuntimeScalar` carries its own type. We need a small + mapping table; the easy mistake is emitting SX_DOUBLE for things + that came in as integers, which inflates files and breaks + byte-level diff with upstream. +3. **UTF-8 flag.** Perl tracks SVf_UTF8 separately from byte content. + PerlOnJava strings are Java `String` (UTF-16 internal) — we already + have `RuntimeScalar.isUtf8()`-equivalent logic for sprintf etc. + Reuse it; otherwise SX_SCALAR vs SX_UTF8STR will be wrong and + round-tripping through real perl will mojibake. +4. **Hook compatibility.** `STORABLE_freeze` returns a list `($cookie, + @refs)`. Our YAML implementation already calls hooks; we just need + to emit the SX_HOOK frame around the hook output. +5. **Endianness on retrieve.** Network-order files are unambiguous. + Native-order files include the byte-order signature; we should + accept any signature and just byte-swap on read. JVM is always + big-endian internally for `DataInputStream`, so reading + native-LE files needs explicit reordering of multi-byte ints and + doubles. This is straightforward but easy to get wrong — fixtures + from a real LE box and a real BE box (or hand-crafted hex) are part + of the Phase-1 test harness. +6. **Storable version skew.** Upstream is at major=2. Older majors + (0, 1) are extinct in the wild but `CPAN::Meta::YAML`-style + fallbacks may still emit them. We refuse with the same message + upstream uses: `Unsupported Storable version`. + +## Test strategy + +- Unit fixtures in `src/test/resources/storable/fixtures/`: pairs of + `.pl` source + `.bin` produced by system perl, covering each opcode. + Build script regenerates them with `perl -MStorable -e 'nstore …'`. +- jperl test: read every fixture, compare against `Data::Dumper` + golden output. +- Differential round-trip test (Phase 2+): jperl-encode → write tmp + file → invoke system `perl` to decode → diff against expected. + Skipped automatically if `perl` is not on `$PATH` (CI must guarantee + it is). +- Existing tests in `src/test/resources/Storable*.t` continue to pass + unchanged — they only assert jperl→jperl round-trip semantics. +- Real-world smoke: `jcpan -t Mojolicious::Plugin::Toto` (or any + module) must not show "retrieve failed" on a CPAN cache last + written by system perl, and vice versa. + +## Files to add/touch + +- New: `src/main/java/org/perlonjava/runtime/perlmodule/storable/Opcodes.java` +- New: `src/main/java/org/perlonjava/runtime/perlmodule/storable/NativeReader.java` +- New: `src/main/java/org/perlonjava/runtime/perlmodule/storable/NativeWriter.java` +- Edit: `src/main/java/org/perlonjava/runtime/perlmodule/Storable.java` + (delegate `store`/`retrieve`/`freeze`/`thaw` to the new readers/writers, + keep YAML reader as legacy fallback) +- Edit: `src/main/perl/lib/Storable.pm` (POD update; remove the + "human-readable YAML format" claim, document canonical-mode parity) +- New tests: `src/test/resources/storable/native_decode.t`, + `src/test/resources/storable/native_roundtrip.t`, + `src/test/resources/storable/fixtures/*` +- Edit: `dev/modules/README.md` (add row for this doc, update Storable + status) +- Edit: `AGENTS.md` "Partially Implemented Features" table — add a + Storable row pointing at this doc. + +## Progress Tracking + +### Current Status: Phase 1 (decoder) and Phase 2 (encoder) complete. + +### Completed Phases + +- [x] **Stage A — foundation** (2026-04-29, commit `20a3b3d96`) + - New package `org.perlonjava.runtime.perlmodule.storable` with + `Opcodes` (SX_* constants), `StorableContext` (cursor, seen-table, + classname-table, byte-order helpers), `Header` (`pst0` magic + + netorder/native + version/sizeof gates), + `StorableReader` (top-level dispatch switch), `OpcodeReader` SPI, + `StorableFormatException`, and group-helper stubs + (`Scalars`/`Refs`/`Containers`/`Blessed`/`Hooks`/`Misc`). + - Fixture generator at `dev/tools/storable_gen_fixtures.pl`, + 37 binary fixtures committed under + `src/test/resources/storable_fixtures/` covering scalars, refs, + containers, blessed, hooks, regexp, native and network byte order. + - `StorableReaderTest` JUnit harness with 11 baseline tests. + - Canary opcodes implemented: SX_UNDEF, SX_SV_UNDEF, SX_SV_YES, + SX_SV_NO, SX_BOOLEAN_TRUE, SX_BOOLEAN_FALSE, SX_OBJECT (backref). + +- [x] **Stage B — per-opcode implementations, in parallel** (2026-04-29, + commit `889e27b67`).

Reverse direction (system perl → jperl) was + already working since Phase 1. + +### Next Steps (Phase 2.x — encoder polish) + +The remaining work is a mix of small encoder tweaks and a few larger +items that need careful design. Each entry below carries enough +detail that a future implementer (human or agent) can pick it up +without re-tracing the source. + +#### 1. `$Storable::canonical` — sorted hash-key emission ✅ landed (commit `c324e14cc`) + +**encoder-polish-agent** + +Affects: `canonical.t` (all 8 tests), parts of `dclone.t`. + +* Currently `Containers.java`-equivalent code in `StorableWriter` + iterates `hv.elements.entrySet()` in insertion order, which Java's + `LinkedHashMap` preserves but Perl's hash iteration randomises. + Tests that compare frozen byte streams across two perls fail + whenever `$Storable::canonical = 1` is set. +* Implementation: in `StorableWriter.writeHashBody`, when the + caller has set `$Storable::canonical`, sort the keys + byte-lexicographically (matching upstream's `qsort` of UTF-8 byte + representations, see `store_hash` at `Storable.xs ~L2750`). Use + `Arrays.sort(keys)` with `Comparator.comparing(...)` against the + UTF-8-encoded key bytes. +* Wire the Perl-level `our $canonical` in `Storable.pm` through to + the writer. `Storable.pm` already has `our $canonical = 0;`. + Either (a) read `GlobalVariable` directly from `StorableWriter`, + or (b) thread a flag through `freezeImpl`/`storeImpl` in + `Storable.java`. Option (b) is cleaner. +* Test plan: enable `canonical.t` in `dev/import-perl5/config.yaml`, + expect 8/8 pass. + +#### 2. `SX_REGEXP` writer — `qr//` pattern + flags ✅ landed (commit `c324e14cc`) + +**regexp-agent** + +Affects: `regexp.t` (full 64 tests, currently bails after 8). + +* Currently `StorableWriter.dispatchReferent` for `RuntimeScalarType.REGEX` + throws `"storing regexes not yet supported by encoder"`. +* Wire format (Storable.xs `store_regexp`, search for `SX_REGEXP`): + ``` + SX_REGEXP + ``` + Both lengths use the small/large convention (1 byte if ≤ LG_SCALAR, + high-bit + U32 otherwise). +* Where to source the pattern + flags: `RuntimeRegex` (which is what + `RuntimeScalar`'s value field carries when type is `REGEX`) exposes + the original Perl pattern source and a flags string. Look in + `src/main/java/org/perlonjava/runtime/runtimetypes/RuntimeRegex.java` + for the public accessors — they should already be there for + `Data::Dumper`-style stringification. +* Reader side: `Misc.readRegexp` is a refusal stub; replace it. + Build a `RuntimeRegex` via the same constructor `qr//` uses + (`RuntimeRegex.compile(patternBytes, flagsString)` or similar). +* Cross-perl interop: byte-for-byte identical output to upstream + matters here (`regexp.t` runs `is_deeply` on round-tripped patterns). +* Test plan: enable `regexp.t` in config.yaml, expect 64/64. + +#### 3. `SX_VSTRING` / `SX_LVSTRING` writer — version strings ✅ landed (commit `c324e14cc`) + +**vstring-agent** + +Affects: `blessed.t` test ~57 (the WeirdRefHook v-string subtest), +parts of `freeze.t`. + +* Currently both refuse with `"misc-agent: SX_VSTRING not yet + implemented"` on the read side, and the write side falls through + to plain string encoding so the v-string magic is lost on retrieve. +* Wire format: same shape as `SX_SCALAR`/`SX_LSCALAR` — length-prefixed + bytes. The receiver attaches a v-string magic to the resulting SV + (via `sv_magic(sv, NULL, PERL_MAGIC_vstring, vstr_pv, vstr_len)` + in upstream). +* PerlOnJava has a `RuntimeScalarType.VSTRING` already. Check + `src/main/java/org/perlonjava/runtime/runtimetypes/RuntimeScalar.java` + for the v-string constructor and accessors. +* On store: detect VSTRING type, emit SX_VSTRING/LVSTRING with the + v-string bytes followed by the textual scalar (per + `retrieve_vstring` at `Storable.xs L5833` — note the v-string + bytes come FIRST, then a regular scalar opcode for the stringy + part). +* On retrieve: the body is ` ` and then + a recursive opcode for the regular scalar. Build a + `RuntimeScalar(VSTRING)` with both pieces. +* Test plan: enable nothing extra (the gain is more `blessed.t` + tests reaching plan completion, not flipping a whole file green). + +#### 4. `SX_HOOK` write side ✅ landed (commit `6fb5ac09d`) + +`STORABLE_freeze` is invoked, cookie + sub-refs are emitted with +the SHF_NEED_RECURSE chain when needed, and the reader's +`Hooks.readHook` handles `STORABLE_attach` as a class-level +alternative to `STORABLE_thaw` (Storable.xs L5119-5172). Verified +with `attach_singleton.t` (16/16 clean), `circular_hook.t` (9/9 +clean), and `attach_errors.t` (39/40, was 13/40). + +#### 5. `SX_OVERLOAD` writer ✅ landed (commit `5748eaa6d`) + +Refs whose referent is blessed into an overload-pragma class are +emitted as `SX_OVERLOAD` instead of `SX_REF`, matching upstream +`store_ref` at `Storable.xs L2350-2354`. The reader has always +supported it via `Refs.readOverload`. + +#### 6. `SX_WEAKREF` / `SX_WEAKOVERLOAD` writer ✅ landed (commit `c324e14cc`) + +**encoder-polish-agent** + +Affects: `weak.t` (when imported — currently skipped due to +`List::Util was not built` upstream-test guard, but a future +build may run it). + +* Currently `StorableWriter.dispatch` always emits plain + `SX_REF`/`SX_OVERLOAD` for inner refs. +* Detection: PerlOnJava tracks weak references via + `WeakRefRegistry`. The reader uses `WeakRefRegistry.weaken()` on + retrieval; the writer should consult `WeakRefRegistry.isWeak(refScalar)` + (or whatever the runtime exposes) and pick the weak opcode. +* The wire layout is identical to `SX_REF`/`SX_OVERLOAD`; only the + opcode byte differs: + ``` + SX_WEAKREF = 27 // = 0x1B + SX_WEAKOVERLOAD = 28 // = 0x1C + ``` + (See `Opcodes.java` and Storable.xs L168-169.) +* Round-trips inside jperl already work (the reader's `readWeakRef` + invokes `WeakRefRegistry.weaken`). The visible bug is when a + weakened ref crosses to system perl, which receives a strong ref + instead. +* Test plan: enable `weak.t` once it can run; or write a + jperl→system-perl smoke test that checks weakness preservation. + +#### 7. Hash-key UTF-8 flag handling on the writer ✅ landed (commit `c324e14cc`) + +**encoder-polish-agent** + +Affects: any test that round-trips non-ASCII hash keys via +`SX_FLAG_HASH`; `utf8hash.t` post-completion. + +* Currently `StorableWriter.writeHashBody` always emits `SX_HASH` + (without the per-key flag byte). The reader handles + `SX_FLAG_HASH` correctly (Containers.java), but the writer never + produces it. +* Detection: PerlOnJava strings carry their UTF-8-or-not state via + `RuntimeScalar.type` (`STRING` is utf8-flagged, `BYTE_STRING` is + not). For hash KEYS the encoding lives in the key string itself + (`hv.elements.keySet()` returns Java `String`s, which are UTF-16 + internally; the original UTF-8-flag-ness is lost at the Java + boundary). +* The simplest correct rule: if any key contains a code point + ≥ 0x80, emit `SX_FLAG_HASH` and set `SHV_K_UTF8 = 0x01` on those + keys. Hash flags byte = 0 (we don't model RESTRICTED_HASH yet). +* Wire format (Storable.xs `store_hash` flag-hash branch): + ``` + SX_FLAG_HASH N×{ value, , , } + ``` +* Test plan: utf8hash.t round-trips successfully (currently bails + at test 26 on `Not a SCALAR reference`, mostly unrelated, but + exposes a UTF-8 mismatch downstream). + +#### 8. Top-level ref-of-ref level loss ✅ landed (commit `c324e14cc`) + +**ref-of-ref-agent (case 4 still @Disabled — see body)** + +Affects: `overload.t` test 4-5, `freeze.t` "VSTRING" subtests, +parts of `dclone.t`, parts of `blessed.t`. Probably ~5-10 specific +assertions across the upstream suite. + +**Root cause.** Our container readers (`Containers.java`) +return already-wrapped `ARRAYREFERENCE`/`HASHREFERENCE` scalars +(structurally one ref level above bare), versus upstream's +`retrieve_array` which returns a bare `AV`. So in our model: + +| Wire | Our readers produce | Upstream produces | +|------|---------------------|-------------------| +| `SX_HASH` | HASHREFERENCE (1 ref) | bare HV (0 ref) | +| `SX_REF + SX_HASH` | ? | RV-to-HV (1 ref) | +| `SX_REF + SX_REF + SX_HASH` | ? | RV-to-RV-to-HV (2 ref) | + +For each `SX_REF`, upstream's `retrieve_ref` does `SvRV_set(rv, sv)` +adding ONE ref level on top of the body. Then `do_retrieve` adds +ONE MORE via `newRV_noinc`. Our `Storable.thaw` adds one level only +when the body wasn't a reference, so the totals come out correct +for most cases — but `SX_REF + SX_BLESS + SX_HASH` becomes a +problem: the body produces `HASHREFERENCE-blessed` (1 ref), our +`Refs.readRef.installReferent` collapses (correct for the inner-ref +case `[\@a]`) but loses a level for the top-level case +`freeze \$blessed_ref`. + +**Why a peek-and-decide doesn't work.** A trivial rule like +"`installReferent` wraps when the body opcode is `SX_REF`, collapses +otherwise" handles `\\@a` but breaks `[\$blessed]` (and vice versa). +The information that disambiguates the two cases — whether the +SX_REF is "redundant given our type system" or "really adds a +level" — isn't in the wire bytes; it's in the data shape we want +to reproduce. + +**Three viable fixes**, in increasing order of invasiveness: + +a. **Bare-container sentinel.** Have `Containers.readArray` / + `readHash` return a `RuntimeScalar` with a non-reference type + (e.g. add a private `STORABLE_BARE_AV` / `STORABLE_BARE_HV` + value to `RuntimeScalarType` or use a side-table on + `StorableContext`). `Refs.readRef` checks the marker and either + collapses (if marked) or wraps (otherwise). After installing, + the marker is consumed. Storable.thaw treats the result like + any other scalar. + + Pros: keeps the container readers unchanged for non-Storable + callers; localised change. Cons: introduces a transient type + only Storable understands. + +b. **Refactor container readers to return bare values.** Make + `Containers.readArray` return a `RuntimeArray` (not a + `RuntimeScalar`). The dispatcher returns `RuntimeBase` instead + of `RuntimeScalar`. `Refs.readRef` always wraps; + `Storable.thaw` always wraps. This is the closest match to + upstream's data flow. + + Pros: clean, matches upstream model. Cons: every dispatcher + site needs to handle the wider return type. + +c. **Always-wrap + emit SX_REF wrapper everywhere.** Drop the + "strip one level" in `emitTopLevel`, always emit a SX_REF + wrapper, mirror with always-wrap on the read side. Adds one + byte to every output, more importantly DIVERGES from upstream + wire format — our jperl-written files would no longer be + readable by system perl. Reject this option. + +Recommended: **option a** (bare-container sentinel). Smallest +diff, no perf impact (one extra byte field on `StorableContext`, +one branch in `Refs.readRef`). + +Sketch: +```java +// StorableContext additions: +private boolean lastWasBareContainer = false; +public boolean takeBareContainerFlag() { + boolean v = lastWasBareContainer; + lastWasBareContainer = false; + return v; +} +public void markBareContainer() { lastWasBareContainer = true; } + +// In Containers.readArray / readHash: +RuntimeScalar result = av.createAnonymousReference(); +c.recordSeen(result); +// ... fill in elements ... +c.markBareContainer(); +return result; + +// In Refs.readRef (new logic): +boolean wasBare = c.takeBareContainerFlag(); +RuntimeScalar referent = r.dispatch(c); +boolean bodyWasBare = c.takeBareContainerFlag(); +if (bodyWasBare) { + // body was a fresh container — collapse, the SX_REF was + // redundant given our types. + refScalar.set(referent); // or .set(arr.createReference()) etc. +} else { + // body was already a "ref level" thing — wrap. + refScalar.set(referent.createReference()); +} +``` + +Test plan: enable `overload.t`, `freeze.t`, `dclone.t` once +landed; expect ~10 additional passing assertions across them. + +#### 9. Tied container freeze/retrieve ✅ landed (commit `c324e14cc`) + +**tied-agent (encoder + reader; SX_TIED_KEY/IDX and SHT_EXTRA refused with clearer message)** + +Affects: `tied.t` (25 tests), `tied_hook.t` (28 tests), +`tied_items.t` (post-test-2 cases), the `SHT_EXTRA` branch of +`Hooks.allocatePlaceholder` (currently throws). + +**Wire format** (Storable.xs `retrieve_tied_array`/`hash`/`scalar`, +L5502-L5610): +``` +SX_TIED_ARRAY // = the inner tying object +SX_TIED_HASH +SX_TIED_SCALAR +``` +Plus `SX_TIED_KEY ` and `SX_TIED_IDX ` +for tied magic on individual hash entries / array slots. + +**Read path.** Currently `Misc.readTiedArray`/`readTiedHash`/ +`readTiedScalar` throw a refusal. Replace with: + +1. Allocate a placeholder container (`RuntimeArray` / `RuntimeHash` + / `RuntimeScalar`) and recordSeen it in the seen-table. +2. Recurse: `RuntimeScalar inner = top.dispatch(c)` — this is the + tying object (a blessed ref to the implementation class). +3. "Tie" the placeholder to the inner object. PerlOnJava's + internal `tie` operator lives in + `src/main/java/org/perlonjava/runtime/perlmodule/AttributeHandlers.java` + or similar — find the static helper that takes a + `(target, classname, args...)` and installs tied magic. + Concretely: `RuntimeTiedHashProxyEntry` is the runtime hook that + intercepts hash operations; we need to wire it via the standard + `tie %h, $class, @args` mechanism, except the `$class` is + already known (from blessing on the inner) and `@args` are + replaced by the inner object itself. +4. Return the tied container. + +The hardest part is step 3 — the path from "I have a placeholder +hash and an already-instantiated tying object" to "the placeholder +now delegates all operations to the object" goes through code +that's currently only reachable from the `tie` operator's parser +output. Likely needs a new public helper in the tie infrastructure. + +**Write path.** Detect tied containers in `dispatchReferent`: +inspect whether the underlying `RuntimeArray`/`RuntimeHash` carries +tied magic (look for an `isTied()` method or a non-null +`tiedObject` field). If yes, emit `SX_TIED_ARRAY`/`HASH`/`SCALAR` +followed by `dispatch(tiedObject)`. Keep tag bookkeeping in mind: +the placeholder gets a tag, the inner gets the next tag. + +**Tied hooks** (`tied_hook.t`): when both `STORABLE_freeze` and +tied magic apply, upstream's `store_hook` uses the SHT_EXTRA +sub-type with an `eflags` byte carrying `SHT_THASH`/`TARRAY`/ +`TSCALAR` (Storable.xs L3624-L3653). Reader side already has the +`SHT_EXTRA` slot in `Hooks.allocatePlaceholder`; replace its +`throw` with a tied-placeholder allocation following the readTied +path above, then read the magic-object into the trailing `` +position. + +**Test plan**: enable `tied.t`, `tied_hook.t`, `tied_items.t` +(currently all excluded). Realistic target: most of `tied.t`'s 25 +tests plus ~80% of `tied_items.t`. `tied_hook.t` depends on the +SHT_EXTRA wiring above and may take a second pass. + +#### 10. Drop the YAML writer codepath ✅ landed (commit `5f910dad9`) + +Removed the legacy YAML+GZIP serializer and the in-house +`BINARY_MAGIC = 0xFF` in-memory format from `Storable.java`: + +* `serializeToYAML` / `deserializeFromYAML` / + `convertToYAMLWithTags` / `convertFromYAMLWithTags` / + `convertScalarValue` and the snakeyaml imports — gone. +* `BINARY_MAGIC` constant, `serializeBinary` / + `deserializeBinary` helpers, and the `appendInt` / `appendLong` + / `readInt` / `readLong` byte-buffer utilities they used — gone. +* `compressString` / `decompressString` (GZIP+Base64) — gone. +* The legacy detection branches in `thaw` (`first == 0xFF`, + `first < 0x10` falling through to `decompressString` → + `deserializeFromYAML`) and the legacy YAML fallback in + `retrieve` — gone. `retrieve` now hard-fails with `"not a + Storable file (no pst0 magic)"` for non-pst0 inputs. + +We chose **no migration safety net**: in practice the legacy +in-memory format was only generated by jperl itself, so after this +upgrade users may need to regenerate their `~/.cpan/Metadata` and +similar. The trade-off was lower complexity vs. a one-release +graceful migration; complexity won. + +`Storable.java` shrank from 1176 → 531 lines. The public API +(freeze / nfreeze / thaw / store / nstore / retrieve / dclone / +last_op_in_netorder) is unchanged. Bundled-modules tests still +pass (same 2 pre-existing unrelated failures), and the JUnit +suite is fully green. + +Test plan: ensure `make` and `make test-bundled-modules` stay +green throughout. + +#### 11. PR-side: re-enable upstream tests and watch the count tick down + +Each time one of the items above lands, check whether any +`dev/import-perl5/config.yaml` exclusions can be removed. Re-run: + +``` +rm -rf src/test/resources/module/Storable +perl dev/import-perl5/sync.pl +JPERL_TEST_FILTER=Storable ./gradlew testModule +``` + +Goal at the end of Phase 2.x: the only remaining excludes are +genuinely-unsupported features (legacy 0.6 binary, 4 GiB +allocations, fork-based threads tests, malice fuzz with +specific Perl-version croak wording). + +### Open Questions + +- Do we want a config switch (`$Storable::PERLONJAVA_LEGACY_YAML = 1`) + for users who relied on the YAML output being human-readable for + debugging?
