Glock" Date: Tue, 31 Mar 2026 22:17:35 +0200 Subject: [PATCH 03/31] fix: UNIVERSAL::can must not consider AUTOLOAD-dispatched methods Perl 5's can() only returns true for methods that are actually defined in the class hierarchy. It should NOT return true for methods that would be handled by AUTOLOAD. Before this fix, can() delegated to findMethodInHierarchy() which includes AUTOLOAD fallback, causing can("anything") to return true for any class with AUTOLOAD. This broke Module::Install's preload mechanism which uses can() to discover extension methods. The fix adds isAutoloadDispatch() which detects when a method resolution came from AUTOLOAD rather than a direct definition, while correctly handling edge cases like can("AUTOLOAD") itself.

Glock" Date: Tue, 31 Mar 2026 22:48:53 +0200 Subject: [PATCH 04/31] fix: goto &sub now propagates wantarray context + eval{} shares @_ with caller Two bugs fixed: 1. goto &sub tail call trampoline used ILOAD 2 (enclosing method own callContext) instead of the call-site context. This caused wantarray to always return undef (void) inside the target sub. Fixed in both EmitSubroutine.java (function calls) and Dereference.java (method calls) by using the saved callContextSlot. 2. eval { BLOCK } was transformed to sub { }->(@_) which expanded @_ into a NEW RuntimeArray, breaking Perl 5 semantics where eval {} shares @_ with the enclosing sub. Fixed by detecting eval blocks (SubroutineNode.useTryCatch) and passing the caller RuntimeArray directly via apply() instead of the args-expansion path.

Glock" Date: Wed, 1 Apr 2026 00:03:10 +0200 Subject: [PATCH 07/31] fix: CORE::GLOBAL:: override fails when caller is RHS of operator When a CORE::GLOBAL:: overridden operator (like caller) appeared as the right-hand side of an infix operator (e.g., $x = caller), parsing failed with "Bad name after CORE::GLOBAL::::". Root cause: ParsePrimary.parsePrimary() captured startIndex before TokenUtils.consume() skipped whitespace. When CORE::GLOBAL:: tokens were inserted at startIndex, a whitespace token ended up between GLOBAL:: and the operator name, causing parseSubroutineIdentifier to fail validation. Fix: Skip whitespace from startIndex to find the actual operator token position before inserting the CORE::GLOBAL:: prefix tokens. Also includes: DBIx::Class support infrastructure (DBI version, DSN translation shim for DBD::SQLite via JDBC, sqlite-jdbc dependency, parse_abstract in ExtUtils::MM_Unix).

It should NOT return true for methods that would be handled by AUTOLOAD. Before this fix, can() delegated to findMethodInHierarchy() which includes AUTOLOAD fallback, causing can("anything") to return true for any class with AUTOLOAD. This broke Module::Install's preload mechanism which uses can() to discover extension methods. The fix adds isAutoloadDispatch() which detects when a method resolution came from AUTOLOAD rather than a direct definition, while correctly handling edge cases like can("AUTOLOAD") itself.

This caused wantarray to always return undef (void) inside the target sub. Fixed in both EmitSubroutine.java (function calls) and Dereference.java (method calls) by using the saved callContextSlot. 2. eval { BLOCK } was transformed to sub { }->(@_) which expanded @_ into a NEW RuntimeArray, breaking Perl 5 semantics where eval {} shares @_ with the enclosing sub. Fixed by detecting eval blocks (SubroutineNode.useTryCatch) and passing the caller RuntimeArray directly via apply() instead of the args-expansion path.

Root cause: ParsePrimary.parsePrimary() captured startIndex before TokenUtils.consume() skipped whitespace. When CORE::GLOBAL:: tokens were inserted at startIndex, a whitespace token ended up between GLOBAL:: and the operator name, causing parseSubroutineIdentifier to fail validation. Fix: Skip whitespace from startIndex to find the actual operator token position before inserting the CORE::GLOBAL:: prefix tokens.

Stash hash redirect resolution (GlobalVariable.java): When *PKG:: = \%OtherPkg:: redirects a package stash, symbolic glob access like *{"PKG::name"} now resolves through the redirect to create entries in the correct package symbol table. Critical for the local *__ANON__:: = $namespace; *{"__ANON__::$name"} pattern used by Package::Stash::PP. 2. Glob access in void context (EmitVariable.java): The JVM backend skipped all variable access in void context as an optimization. However, glob access (*{"name"}) has vivification side effects. Now glob access emits code even in void context, with a POP to discard the unused result. Together these fixes unblock namespace::clean, required by DBIx::Class and many other CPAN modules.

Glock" Date: Wed, 1 Apr 2026 10:34:37 +0200 Subject: [PATCH 15/31] fix: version comparison, isPackageLoaded, and cp overwrite bugs - VersionHelper.normalizeVersion: right-pad minor version digits to 3 chars so 0.01 normalizes to v0.10.0 (not v0.1.0). Fixes Clone::Choose version check that blocked Hash::Merge and most DBIx::Class tests. - VersionHelper.compareVersion: use raw version in error messages (matching Perl behavior) instead of normalized dotted form. - GlobalVariable.isPackageLoaded: exclude sub-package entries so isPackageLoaded does not match sub-packages. - ExtUtils::MakeMaker._shell_cp: rm -f before cp to handle read-only files installed by ExtUtils::Install (mode 0444).

Glock" Date: Wed, 1 Apr 2026 13:06:52 +0200 Subject: [PATCH 28/31] fix: prevent VerifyError from JVM local variable slot reuse across branches When a child scope exits, propagate its max local variable index to the parent scope. This prevents local variable slots allocated inside conditional branches (if/else blocks) from being reused in subsequent code with incompatible types. Without this fix, the JVM verifier fails with VerifyError when the same slot holds different types in different branches (e.g., int vs reference, or RuntimeScalar vs RegexState). ASM's COMPUTE_FRAMES merges these as Top or java/lang/Object, causing "Bad type on operand stack" errors. This fixes: - File::stat loading (use File::stat) - DBIx::Class t/00describe_environment.t VerifyError - Any complex anonymous sub combining eval{}, regex in conditionals, and short-circuit operators (&&/and) with eval in conditions Root cause: ScopedSymbolTable.exitScope() popped the child scope but left the parent's local variable index unchanged, allowing the allocator to reuse slots that still had types from the child scope at JVM branch merge points.

Fixes op/signatures.t (0/0 -> 643/908). - utf8::upgrade: remove ($) prototype to match Perl 5 (no prototype). Without this, "utf8::upgrade my $x = ..." parsed incorrectly as named unary, taking only "my $x" as argument. Fixes op/index.t test 122.
