+
+### Current Investigation: t/020Easy.t Carp.pm Error
+
+**Status:** Partially debugged - the error is intermittent and context-dependent.
+
+**Symptom:**
+```
+Can't use an undefined value as a GLOB reference at jar:PERL5LIB/Carp.pm line 755
+```
+
+**Key Finding:** The error occurs when:
+1. A bareword filehandle `IN` is opened and read from (`<IN>`)
+2. Log4perl's `%T` layout is used (which calls `Carp::longmess()`)
+3. The `%T` pattern is rendered during logging
+
+**Reproduction Path (simplified):**
+```perl
+open IN, "<", "somefile";
+my @lines = <IN>;  # Sets ${^LAST_FH}
+use Carp;
+my $m = Carp::longmess();  # Sometimes fails with undef GLOB
+```
+
+**What's NOT the issue:**
+- `*{NAME}` slot - now implemented and working
+- `local *$dynamic` - now implemented for interpreter backend
+- `${^LAST_FH}` basic functionality - works in isolation
+
+**Investigation Notes:**
+- The error happens at Carp.pm line 752: `*{"warnings::$_"} = \&$_ foreach @EXPORT;`
+- This code runs when `$warnings::VERSION` is undefined (which it is in PerlOnJava's warnings.pm)
+- The bareword filehandle name check (`*{${^LAST_FH}}{NAME}`) now works
+- Error is NOT reproducible in simple test cases - only in specific call stack contexts
+- May be related to how Carp.pm is loaded/initialized in the presence of active I/O
+
+**Next Steps:**
+1. Add `$VERSION` to PerlOnJava's warnings.pm to skip the problematic code path
+2. Or investigate why `$_` becomes undefined during the foreach loop in certain contexts
+
+## Completed Fixes
+
+### 1. *{NAME} Glob Slot Accessor (Committed 2026-03-18)
+
+**Problem:** `*{$glob}{NAME}` returned empty string instead of the glob's name.
+
+**Root Cause:** The NAME slot was not implemented in RuntimeGlob's `getSlot()` method.
+
+**Fix:** Added case for "NAME" that extracts the name from globName after the last `::`.
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/runtime/runtimetypes/RuntimeGlob.java`
+
+**Commit:** 0a5e92556
+
+### 2. Interpreter: local *$dynamic Support (Committed 2026-03-18)
+
+**Problem:** `local *$probe = sub { ... }` failed with "Assignment to unsupported operator: local"
+
+**Root Cause:** The interpreter's `handleLocalAssignment()` only handled static glob names, not dynamic ones like `*$probe`.
+
+**Fix:** Added case for dynamic glob names (when operand is not IdentifierNode) using LOAD_GLOB_DYNAMIC opcode.
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/backend/bytecode/CompileAssignment.java`
+
+**Commit:** 68d295287
+
+### 3. Interpreter: gethostbyname Opcode (Committed 2026-03-18)
+
+**Problem:** `gethostbyname` was not implemented in the interpreter backend.
+
+**Fix:** Added GETHOSTBYNAME opcode (389) and routing to ExtendedNativeUtils.
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/backend/bytecode/Opcodes.java`
+- `src/main/java/org/perlonjava/backend/bytecode/CompileOperator.java`
+- `src/main/java/org/perlonjava/backend/bytecode/MiscOpcodeHandler.java`
+
+**Commit:** 68d295287
+
+### 4. Bareword Filehandle Method Calls (Committed 2026-03-18)
+
+**Problem:** `IN->clearerr()` failed with "Can't locate object method 'clearerr' via package 'IN'"
+
+**Root Cause:** `isGlobalIODefined()` was checking `glob.value instanceof RuntimeIO` but IO handles are stored in `glob.IO`, not `glob.value`.
+
+**Fix:** Changed `isGlobalIODefined()` to check `glob.IO.getDefinedBoolean()` instead.
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/runtime/runtimetypes/GlobalVariable.java`
+
+**Commit:** 3d0bf9b59
+
+**Tests Fixed:** Unblocked 15+ tests in t/020Easy.t (from 1 to 16 passing)
+
+### 5. $( and $) Special Variables (Committed 2026-03-18)
+
+**Problem:** `$(` and `$)` (real/effective GID) were not working - returned literal `$(` in strings.
+
+**Root Cause:** 
+1. Variables not initialized with actual GID values
+2. `(` and `)` not in special variable character lists
+3. `(` and `)` in non-interpolating character list blocked string interpolation
+
+**Fix:**
+- Initialize `$(` and `$)` in GlobalContext with `getgid()`/`getegid()` values
+- Add `(` and `)` to special variable character lists in IdentifierParser
+- Remove `(` and `)` from non-interpolating character list
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/runtime/runtimetypes/GlobalContext.java`
+- `src/main/java/org/perlonjava/frontend/parser/IdentifierParser.java`
+- `src/main/java/org/perlonjava/frontend/parser/StringSegmentParser.java`
+
+**Commit:** a82bf0c66
+
+**Tests Fixed:** t/033UsrCspec.t - all 17 tests now pass (was 5 failing)
+
+### 6. AUTOLOAD $AUTOLOAD Variable (Committed Earlier)
+
+**Problem:** `$AUTOLOAD` was not being set correctly in two scenarios:
+1. Method call cache hits were skipping the `$AUTOLOAD` assignment
+2. `our $AUTOLOAD` declared in different packages within the same lexical scope was silently ignored
+
+**Fix:** 
+- Added `$AUTOLOAD` assignment in the cache hit path in `RuntimeCode.java`
+- Modified `SymbolTable.addVariable()` to create new entries for `our` declarations in different packages
+
+**Files Changed:**
+- `src/main/java/org/perlonjava/runtime/runtimetypes/RuntimeCode.java`
+- `src/main/java/org/perlonjava/frontend/semantic/SymbolTable.java`
+
+**Commit:** 9f2d0aaf2
+
+### 7. Parser/Runtime Fixes (Committed Earlier)
+
+- `sprintf %s` treating "INFO" as Infinity
+- `oct("0")` crash
+- `splitpath()` returning wrong component
+- Newlines between sigil and variable name
+
+## Remaining Issues
+
+### Issue 1: Carp.pm / warnings.pm Interaction
+
+**Symptom:** t/020Easy.t tests 17-21 - error after %T logging:
+```
+Can't use an undefined value as a GLOB reference at jar:PERL5LIB/Carp.pm line 755
+```
+
+**Root Cause:** PerlOnJava's warnings.pm lacks `$VERSION`, causing Carp.pm to execute a workaround code path (line 752) that fails in certain contexts.
+
+**Proposed Fix:** Add `our $VERSION = "1.78";` to PerlOnJava's warnings.pm to skip the problematic code path.
+
+**Note:** 4 of the 5 failing tests in t/020Easy.t are just filename pattern mismatches (test expects "020Easy.t" but gets "-" from stdin). Only 1 failure is the Carp.pm error.
+
+**Affected Tests:**
+- t/020Easy.t (tests 17-21)
+
+### Issue 2: caller() Stack Trace Format
+
+**Symptom:** Stack traces from `Carp::shortmess` include internal PerlOnJava frames.
+
+**Example from t/022Wrap.t:**
+```
+Expected: 'File: 022Wrap.t Line number: 70 package: main trace: at 022Wrap.t line 70'
+Got:      'File: 022Wrap.t Line number: 70 package: main trace: Log::Log4perl::Appender::log() called at ... line 1115, ...'
+```
+
+**Root Cause:** The `caller()` implementation is exposing internal call frames that Perl would filter out.
+
+**Fix Needed:** Review `ExceptionFormatter.formatException()` and filter out internal frames from Log::Log4perl's perspective.
+
+**Affected Tests:**
+- t/022Wrap.t (2 failures)
+- t/024WarnDieCarp.t (11 failures) - tests 51-53, 58-62, 67, 69-70
+- t/051Extra.t (2 failures) - line number reporting
+
+### Issue 3: File Permissions (stat/chmod)
+
+**Symptom:** t/026FileApp.t tests 6-7 fail comparing expected vs actual file permissions.
+
+**Example:**
+```perl
+# Expected: '488' (octal 0750)
+# Got: '511' (octal 0777)
+```
+
+**Root Cause:** Likely issue with `umask` handling or `chmod` implementation.
+
+**Affected Tests:**
+- t/026FileApp.t (tests 6-7, 25)
+
+### Issue 4: Safe.pm / Opcode.pm
+
+**Symptom:** t/041SafeEval.t tests 4-5, 20 fail.
+
+**Root Cause:** PerlOnJava's Safe.pm implementation may not properly restrict opcodes.
+
+**Affected Tests:**
+- t/041SafeEval.t (3 failures)
+
+### Issue 5: Source Filters (###l4p)
+
+**Symptom:** t/049Unhide.t fails - the `###l4p` source filter mechanism doesn't work.
+
+**Root Cause:** Log::Log4perl uses a source filter to hide/unhide statements prefixed with `###l4p`. PerlOnJava may not support this source filtering.
+
+**Affected Tests:**
+- t/049Unhide.t (1 failure)
+
+### Issue 6: DESTROY Message
+
+**Symptom:** t/016Export.t test 16 fails - expected DESTROY message not appearing.
+
+**Test:**
+```perl
+# Expected: 'Log::Log4perl::Appender::TestBuffer destroyed'
+# Got: ''
+```
+
+**Root Cause:** The `DESTROY` method on TestBuffer may not be called during global destruction, or the message is not being captured correctly.
+
+**Affected Tests:**
+- t/016Export.t (1 failure)
+
+## Priority Order
+
+1. **Carp.pm undef GLOB** - Blocks 5 tests in t/020Easy.t
+2. **caller() stack trace format** - Affects 15 tests across multiple files
+3. **DESTROY message** - May be a minor timing/output issue
+4. **File permissions** - Likely straightforward fix
+5. **Safe.pm** - May require significant work
+6. **Source filters** - May require parser changes
+
+## Recent Debugging Session (2026-03-18)
+
+### PR 328 Test Timeout Investigation
+
+**Symptom:** Tests reported as timeouts in PR 328:
+```
+✗ io/crlf_through.t      942/942   0/0   -942
+✗ io/through.t           942/942   0/0   -942
+✗ op/heredoc.t            66/138   0/0    -66
+✗ op/tie.t                45/95    0/0    -45
+✗ lib/croak.t             44/334   0/334  -44
+```
+
+**Root Cause Found:** Staged (but uncommitted) changes had accidentally removed the `ForkOpenCompleteException` catch blocks from `RuntimeCode.java`. These catch blocks are essential for the fork-open emulation feature added in commit 764c256cc.
+
+**Impact:** Without the exception handling:
+- `exec` inside fork-open patterns (`open FH, "-|"; if (!$pid) { exec @cmd }`) throws an uncaught exception
+- Tests that spawn subprocesses (fresh_perl_is, run_multiple_progs, pipe opens) hang or fail
+- All tests using `test.pl`'s subprocess spawning are affected
+
+**Fix:** Restored the files from the committed version:
+```bash
+git reset HEAD -- .
+git checkout -- .
+```
+
+**Verification:** After restoring, `grep -c "ForkOpenCompleteException"` returns 5 in RuntimeCode.java (correct).
+
+**Note:** The tests themselves are NOT broken - they just take longer than the CI timeout due to JVM startup overhead for each subprocess. The 0/0 results were from the uncaught exception causing early termination.
+
+### Next Steps for PR 328
+
+1. **Ensure all files are committed with fork-open emulation intact**
+2. **Consider increasing CI timeout** for subprocess-heavy tests (io/through.t has 942 tests)
+3. **Always verify working tree is clean before testing**
+
+### Additional Fixes (2026-03-18)
+
+#### Fix: $( and $) in regex patterns
+The commit adding `$(` and `$)` variable support caused ExifTool.t to fail because regex patterns containing `$)` were incorrectly interpolating the EGID variable instead of treating `$)` as end-of-string anchor + closing paren.
+
+**Fix:** Added check in `StringSegmentParser.shouldInterpolateVariable()` to skip interpolation of `$(` and `$)` specifically in regex context, while still allowing interpolation in double-quoted strings.
+
+#### Fix: sprintf %c with Inf/NaN regression  
+The sprintf fix for "INFO" being treated as Infinity incorrectly moved `%c` handling before the Inf/NaN check, causing `sprintf "%c", Inf` to format a character instead of erroring.
+
+**Fix:** Only skip the Inf/NaN check for `%s` (string) and `%p` (pointer), while `%c` still goes through the Inf/NaN check.
+
+**Result:** op/infnan.t restored from 1041/1088 back to 1071/1088 (same as master).
+
+### Remaining CI Timeout Issues
+
+The following tests timeout in CI but are NOT regressions - they just take a long time due to JVM startup overhead for subprocess-heavy tests:
+
+- **io/crlf_through.t** (942 tests) - spawns many subprocesses via pipe opens
+- **io/through.t** (942 tests) - spawns many subprocesses via pipe opens  
+- **lib/croak.t** (334 tests) - spawns many subprocesses
+
+These tests pass locally but exceed CI timeout limits. The CI may need longer timeouts for these specific tests.
+
+## How to Test
+
+```bash
+# Run all Log::Log4perl tests
+./jcpan -t Log::Log4perl
+
+# Run a specific test
+cd ~/.cpan/build/Log-Log4perl-1.57* && /path/to/jperl t/020Easy.t
+
+# Quick test for bareword filehandle
+./jperl -e 'open IN, "</etc/passwd"; IN->clearerr(); print "OK\n"; close IN;'
+
+# Quick test for $( and $)
+./jperl -e 'print "GID: $(\nEGID: $)\n";'
+```

+# PR #328 Startup Performance Investigation
+
+## Overview
+
+PR #328 introduced a 2x performance regression that caused io/through.t, io/crlf_through.t, and lib/croak.t tests to timeout in CI. This document details the investigation and fixes.
+
+## Root Cause
+
+Commit a82bf0c66 ("Add support for $( and $) special variables") introduced expensive JNA function calls during static initialization:
+
+```java
+// In GlobalContext.java lines 84-85 (before fix)
+GlobalVariable.getGlobalVariable("main::(").set(NativeUtils.getgid(0));  // $( - real GID
+GlobalVariable.getGlobalVariable("main::)").set(NativeUtils.getegid(0));  // $) - effective GID
+```
+
+These JNA calls (`getgid` and `getegid`) are expensive (~5ms each) and were executed at every startup, including every subprocess fork. This doubled the startup time from ~80ms to ~160ms per process.
+
+## Performance Measurements
+
+| Scenario | Tests in 60s | Startup Time |
+|----------|--------------|--------------|
+| Master branch | 936-942 | ~80ms |
+| After a82bf0c66 | 464-468 | ~160ms |
+| After fix | 942 | ~140ms |
+
+The io/through.t test spawns many subprocesses, so a 2x startup slowdown resulted in exactly 2x fewer tests completing.
+
+## Fixes Applied
+
+### 1. Lazy $( and $) Variables (commit b462539b7)
+
+Made $( and $) lazy-loaded via `ScalarSpecialVariable` so JNA calls only happen when the variables are accessed:
+
+**ScalarSpecialVariable.java**:
+```java
+// Added to enum Id:
+REAL_GID,       // $( - Real group ID (lazy, JNA call only on access)
+EFFECTIVE_GID,  // $) - Effective group ID (lazy, JNA call only on access)
+
+// Added to getValueAsScalar():
+case REAL_GID -> {
+    yield new RuntimeScalar(NativeUtils.getgid(0));
+}
+case EFFECTIVE_GID -> {
+    yield new RuntimeScalar(NativeUtils.getegid(0));
+}
+```
+
+**GlobalContext.java**:
+```java
+// Changed from eager initialization to lazy ScalarSpecialVariable
+GlobalVariable.globalVariables.put("main::(", new ScalarSpecialVariable(ScalarSpecialVariable.Id.REAL_GID));
+GlobalVariable.globalVariables.put("main::)", new ScalarSpecialVariable(ScalarSpecialVariable.Id.EFFECTIVE_GID));
+```
+
+### 2. Deferred Module Initialization (commit 15c5c1a83)
+
+Deferred initialization of less commonly used modules to XSLoader::load():
+
+- `UnicodeNormalize` - Has XSLoader in its Perl file
+- `TimeHiRes` - Has XSLoader in its Perl file (updated Time/HiRes.pm)
+- `JavaSystem` - Only needed for java:: integration
+
+Modules kept at startup (no XSLoader in Perl files):
+- `UnicodeUCD`, `TermReadLine`, `TermReadKey`, `FileTemp`, `Encode`
+
+## Current Performance Profile
+
+### Startup Time Breakdown (~140ms total)
+
+| Phase | Time | Notes |
+|-------|------|-------|
+| JVM startup | ~43ms | Inherent to Java |
+| Class loading | ~14ms | 1444 classes loaded |
+| Class initialization | ~50ms | Static blocks, HashMap setup |
+| Bytecode verification | ~33ms | Security verification |
+
+### Profiling Commands Used
+
+```bash
+# Measure tests per 60 seconds
+cd perl5_t/t && timeout 60 ../../jperl io/through.t 2>&1 | grep "^ok" | wc -l
+
+# Measure single startup
+time ./jperl -e '1'
+
+# Profile class loading
+java -Xlog:class+load:file=/tmp/classload.log -cp "build/install/perlonjava/lib/*" \
+    org.perlonjava.app.cli.Main -e '1'
+
+# Profile class initialization  
+java -Xlog:class+init=info:file=/tmp/classinit.log -cp "build/install/perlonjava/lib/*" \
+    org.perlonjava.app.cli.Main -e '1'
+```
+
+## Why Further Optimization is Limited
+
+The ~140ms startup is near-optimal for a JVM application of this complexity:
+
+1. **JVM overhead is fixed** (~43ms) - Cannot be reduced without native compilation
+2. **Class count is necessary** (1444 classes) - Required for Perl compatibility
+3. **Static initialization is minimal** - Most work deferred to runtime
+
+### Potential Future Optimizations
+
+| Approach | Savings | Feasibility |
+|----------|---------|-------------|
+| GraalVM native-image | ~100ms | Low - breaks dynamic class loading |
+| AppCDS (Class Data Sharing) | ~20-30ms | Medium - helps repeated runs only |
+| Reduce class count | Variable | Low - requires major refactoring |
+| Lazy module loading | ~5-10ms | Done - already implemented |
+
+## Files Modified
+
+1. `src/main/java/org/perlonjava/runtime/runtimetypes/ScalarSpecialVariable.java`
+   - Added REAL_GID and EFFECTIVE_GID enum values
+   - Added lazy getters for $( and $)
+
+2. `src/main/java/org/perlonjava/runtime/runtimetypes/GlobalContext.java`
+   - Changed $( and $) to use ScalarSpecialVariable
+   - Deferred UnicodeNormalize, TimeHiRes, JavaSystem initialization
+
+3. `src/main/perl/lib/Time/HiRes.pm`
+   - Enabled XSLoader::load() call for lazy loading
+
+## Verification
+
+```bash
+# Build and test
+make
+
+# Verify io/through.t performance (should be ~940+ tests in 60s)
+cd perl5_t/t && timeout 60 ../../jperl io/through.t 2>&1 | grep "^ok" | wc -l
+
+# Verify $( and $) still work
+./jperl -e 'print "REAL_GID: $(; EFFECTIVE_GID: $)\n"'
+```
