Fix CPAN module compatibility for jcpan DateTime installation#356
Merged
Conversation
…d message
Three fixes that reduce Module::Runtime test failures from 23 to 8:
1. Honor #line directive in use statement caller info
- parseUseDeclaration now uses getSourceLocationAccurate() to get the
#line-adjusted filename and line number for CallerStack.push()
- Fixes t/import_error.t tests where eval'd use statements with #line
directives were reporting wrong locations
2. Prevent %^H hints hash from leaking into require'd modules
- doFile() now saves, clears, and restores %^H around PerlLanguageProvider.executePerlCode()
- In Perl >= 5.11 (which we emulate), hints don't leak into required files
- Fixes tests that check $^H{...} is undef in BEGIN blocks of required modules
3. Fix cached require failure error message
- Changed 'Compilation failed in require at <file>' to 'Attempt to reload <file> aborted.'
- Matches Perl's actual error message for cached compilation failures
- Fixes the 'broken module is visibly broken when re-required' tests
Remaining 8 failures are due to caller()[10] (hints hash per stack frame)
returning undef - this is a known limitation requiring more complex tracking.

In Perl, $Foo::x and $main::Foo::x refer to the same variable, but PerlOnJava stores top-level package symbols without the 'main::' prefix. This caused %main:: (the main stash) to not include entries like 'Foo::' for top-level packages. The fix extends HashSpecialVariable.entrySet() to also include keys that start with a top-level package name (e.g., "Foo::test") when enumerating %main::. This allows Class::Inspector::_subnames to correctly find all child packages. Test results: - Class::Inspector: 55/56 tests pass (1 failure is unrelated INC hook issue) - All unit tests pass Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
When substr() is called with a negative offset that goes before the
beginning of the string, Perl's behavior is:
1. If the adjusted length would still be positive, clip offset to 0
and reduce length by the overshoot amount (no warning)
Example: substr("a", -2, 2) returns "a"
2. If the adjusted length would be non-positive, warn and return undef
Example: substr("hello", -10, 1) warns and returns undef
This also fixes the 4-argument substr replacement behavior to correctly
replace only the extracted portion when clipping occurs.
Example: substr("ab", -3, 2, "X") returns "a" and sets str to "Xb"
Test results:
- All unit tests pass
- Class::Inspector tests pass (no more substr outside of string warnings)

Instead of unconditionally enabling UNICODE_CHARACTER_CLASS (which broke 308 tests in re/charset.t), now properly track the /u modifier and only enable Unicode character class matching when /u is specified.

Perl's error message for a cached compilation failure includes both: - 'Attempt to reload <file> aborted.' - 'Compilation failed in require at <file>' The previous fix only included the first part, which broke comp/require.t test 32.

When a decimal version like '1.0' was passed to version->new(), PerlOnJava was incorrectly setting qv=true and storing 'v1.0' as the original string. This caused CPAN::Meta::Requirements to format versions as '<= v1.0.0' instead of '<= 1.0', breaking CPAN::Meta::Check tests. The fix: - Track the original version string before prepending 'v' for internal use - Set qv=true only if the ORIGINAL input started with 'v' - Store the original input string for stringify(), not the modified one Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
1. Version.java: Strip trailing zeros from double versions
- version->new(1.0203) now stringifies to '1.0203' not '1.020300'
- version->new(1.23) now stringifies to '1.23' not '1.230000'
2. version.pm: Add overload operators that throw errors for math ops
- +, -, *, /, abs, +=, -=, *=, /= now die with
'operation not supported with version object'
Version tests: 93.7% -> 99.5% pass rate (220/221 passing)

Anonymous globs created by 'open(my $fh, ...)' have a null globName and cannot use GlobalVariable to store their SCALAR, ARRAY, and HASH slots.

Parser changes:
- Fix parsing of "bareword { block } args" when bareword is undefined
- Correctly parse as indirect object syntax: (block_result)->bareword(args)
- This matches Perl behavior for try/catch style constructs without imports
Note: t/48rt-115983.t still fails because namespace::autoclean is a stub.
The test expects DateTime to clean imported try/catch from its namespace,
but implementing autoclean properly causes regressions in other tests.

- Remove runtime suppression stack that was breaking local $SIG{__WARN__}
- Handle no warnings; (without arguments) to disable all warnings
- warnings::warnif now properly goes through $SIG{__WARN__} handler
- Test::Warnings::warnings { } now captures warnif warnings correctly
Note: Lexical warning suppression (no warnings category) works at
compile time but does not propagate through module calls at runtime.
This is a known limitation requiring future work to pass warning bits
through the call stack.

Phase 1 of lexical warning scope propagation: - Add scope ID tracking to WarningFlags.java - registerScopeWarnings() assigns unique scope IDs - isWarningDisabledInScope() checks if category is suppressed - Design doc in dev/design/warnings-scope.md This enables "no warnings 'DateTime'" to propagate to warnif() calls in DateTime.pm via the local $^WARNING_SCOPE mechanism.

This allows "no warnings 'Category'" in user code to suppress
warnings::warnif('Category', $msg) calls in library code (e.g., DateTime.pm).
Implementation:
- Add ${^WARNING_SCOPE} global variable to track runtime warning scope
- noWarnings() registers disabled categories with unique scope IDs
- CompilerFlagNode carries scope ID, emits local ${^WARNING_SCOPE} = id
- warnIf() checks ${^WARNING_SCOPE} to see if category is suppressed
- FindDeclarationVisitor detects scope nodes for proper cleanup
Files changed:
- WarningFlags.java: Scope ID tracking infrastructure
- Warnings.java: Register scopes, check in warnIf()
- GlobalContext.java: Initialize ${^WARNING_SCOPE}
- CompilerFlagNode.java: Add warningScopeId field
- StatementParser.java: Pass scope ID to CompilerFlagNode
- EmitCompilerFlag.java: Emit local assignment bytecode
- FindDeclarationVisitor.java: Detect scope nodes for cleanup

The stringConcatWarnUninitialized method was calling getDefinedBoolean() to check for undef values before calling toString(). Both methods trigger FETCH on tied scalars, causing extra FETCH calls.

- Add setVoid() method for operations that don't need the assignment result (like chop/chomp) to avoid unnecessary FETCH-after-STORE - For TIED_SCALAR wrapper in RuntimeScalar.set(), delegate to the tied object's set() method instead of doing FETCH-after-STORE directly - Override set() in TieScalar to do FETCH-after-STORE for actual tied scalars (needed for chained assignments like $s = $tied = value) - TiedVariableBase.set() (used by hash/array proxy entries) just does STORE without extra FETCH, which is correct for those cases This fixes the op/gmagic.t concat-assignment tests (37 passing, up from 31) and the tie_hash.t FETCH count test.

In Perl, the /i flag makes matching case-insensitive for literals,
but does NOT affect Unicode property matching (\p{...}).
Changes:
- RegexPreprocessorHelper: Wrap \p{...} translations in (?-i:...) to
disable case-insensitive matching for property references
- RegexPreprocessor: Skip over \p{...}, \P{...}, \N{...}, \x{...},
\o{...} constructs during case-fold expansion to prevent mangling
property names (e.g., 'k' in 'Blk' was being expanded)
- ExtendedCharClass: Wrap output in (?-i:...) since Perl's (?[...])
applies /i only to literals, not Unicode properties
This fixes re/regex_sets.t tests 26-27 and enables many more tests
to pass (79/88 up from 25/88).

When running 'jperl -MModule' without -e or a script file, PerlOnJava was entering REPL mode and waiting for stdin input, even when called from a subprocess (e.g., via IPC::Open3 in test suites). The fix: 1. If -M/-m modules are specified but no code, check if stdin has data available (pipe/redirection). If not, use minimal code '1;' instead of blocking on stdin. 2. Improved interactive detection to use System.in.available() to check for piped input, not just System.console(). This fixes Test::Needs test suite hanging during 'jcpan DateTime' installation.

In Perl, when you delete a stash entry like delete $Foo::{aliased},
code that was compiled to call aliased() continues to work because
the compiled bytecode holds a direct reference to the CV (code value),
not to the stash entry.
This commit implements the same behavior in PerlOnJava:
1. GlobalVariable.getGlobalCodeRef() now pins RuntimeScalars in a
separate cache that survives stash deletion. When the stash entry
is deleted and later looked up, the pinned reference is returned.
2. Glob assignment (*aliased = *original) now updates the existing
RuntimeScalar value via .set() instead of replacing the map entry.
This ensures cached references see the updated code.
3. BytecodeCompiler caches the RuntimeScalar at compile time via
LOAD_CONST instead of looking it up by name at runtime.
4. Restores the original CPAN::Meta::YAML code that deletes refaddr
from the stash, which now works correctly.

The test target was missing blib/lib in @inc, causing all module tests to fail with Can't locate Module/X.pm errors. Test::Harness runs each test file as a subprocess, so -I flags on the parent process do not propagate. The fix sets PERL5LIB to include $(INST_LIB) and $(INST_ARCHLIB), making the built module available to test subprocesses. This enables jcpan to properly run module tests during installation.

changed the title
When slicing an empty list with (empty_list())[index], the result should be an empty list, not undef. This was causing Test::Tester::find_run_tests() to hang because (caller($d))[3] was returning undef (truthy in list assignment context) instead of empty list when the call stack was exhausted. Added RuntimeList.getSlice() method that implements proper list slice semantics: - Empty list sliced at any index returns empty list - Non-empty list sliced at out-of-bounds index returns undef Updated Dereference.java to use list slice semantics for ListNode cases, while preserving array dereference semantics for other cases like $a[0][1].

Two fixes: 1. Dereference.java: Use local variables to store list and indices before calling getSlice(). This prevents JVM bytecode verifier errors when indices contain function calls that generate complex bytecode with exception handlers. 2. XSLoader.pm: Add a stub that preserves the Java-registered XSLoader::load function when %INC is cleared (e.g., by Perl test files). The stub only defines its own load() if the Java version is not already registered.
