Glock" Date: Tue, 7 Apr 2026 17:33:01 +0200 Subject: [PATCH 2/6] fix: update selectedHandle when tying/untying STDOUT When Test2::Plugin::IOEvents ties STDOUT, print without explicit filehandle was bypassing the tie because RuntimeIO.selectedHandle still pointed to the original untied handle. Fix: TieOperators.tie() and untie() now check if the glob being tied/untied is the currently-selected handle and update selectedHandle accordingly. This ensures print goes through the TieHandle PRINT method. stat(STDOUT) fix was NOT needed: analysis showed that _check_for_change() comparing undef-to-undef is safe, and the TAP formatter dups STDOUT before IOEvents ties it. Result: App::perlbrew tests 57/73 -> 65/73 pass.

"Works with bash" passes. All use `capture_stdout`. + +**Root cause:** `Stat.java` cannot stat filehandles backed by `DupIOHandle` or +`BorrowedIOHandle`.

Inside +`do_install_this` (perlbrew.pm line 1651), `do_capture("$newperl -V:sitelib")` uses +Capture::Tiny. The localized STDOUT doesn't get `selectedHandle` pointed to it, so +`print` inside the capture goes through the old TieHandle → output becomes a Test2 +event instead of being written to the capture temp file → capture returns empty → +`$sitelib = undef` → sitecustomize.pl written to wrong path. + +**Fix:** Same as 7.2.1 — fix `dynamicRestoreState()` or make `setIO()` smarter about +glob identity vs IO identity. + +--- + +#### 7.2.4 `12.sitecustomize.t` — Same root cause as 7.2.3 (1 test, 1 subtest fails) + +**Symptom:** `Received an undefined entry as a parameter` at `App/Perlbrew/Path.pm` +line 18. + +**Root cause:** Identical to 7.2.3.

Mock tracking shows +`do_system` was never called. + +**Root cause:** `do_install_this` calls `maybe_patchperl()` (perlbrew.pm line 1587-1589) +before reaching `do_system`. `maybe_patchperl` uses `Capture::Tiny::capture { system("patchperl --version") }`. +This hits the same selectedHandle/Capture::Tiny issue, causing `maybe_patchperl` to +crash → `do_install_this` dies before reaching the mocked `do_system`. + +**Secondary concern:** Test2::Mock's tracking wrapper uses `goto &$sub` where `$sub` +is a closure-captured lexical coderef: +```perl +# Test2/Mock.pm line 434-439 +$ref = sub { + push @{$sub_tracker->{$param}} => $call; + goto &$sub; # tail call to actual mock sub +}; +``` +If `goto &$sub` with closure-captured coderefs doesn't work correctly in PerlOnJava, +the mock would fail even without the Capture::Tiny issue. + +**Fix:** Primary fix is the Capture::Tiny/selectedHandle fix (7.2.1). After that, verify +`goto &$sub` with closures works. + +--- + +#### 7.2.6 `http-ua-detect-non-curl.t` — `FileSpec.path()` uses Java env (1 test, 1 subtest fails) + +**Symptom:** Expected fake curl from `t/fake-bin/curl` but got `/usr/bin/curl`. + +**Root cause:** `FileSpec.java` line 357 uses `System.getenv("PATH")` instead of reading +from Perl's `%ENV`. The test modifies `$ENV{PATH}` in a BEGIN block to prepend +`t/fake-bin/`, but `System.getenv("PATH")` returns the original JVM process PATH. + +**Code:** +```java +// FileSpec.java line 356-363 +public static RuntimeList path(RuntimeArray args, int ctx) { + String path = System.getenv("PATH"); // BUG: reads Java env, not Perl %ENV + ... +} +``` + +**Fix:** Simple one-line change in `FileSpec.java:357`: +```java +RuntimeHash perlEnv = GlobalVariable.getGlobalHash("main::ENV"); +RuntimeScalar pathScalar = perlEnv.get(new RuntimeScalar("PATH")); +String path = pathScalar.getDefinedBoolean() ? pathScalar.toString() : null; +``` + +**Also affects:** `ArgumentParser.java` line 258 (same `System.getenv("PATH")` for `-S` flag). + +--- + +#### 7.2.7 `util-looks-like.t` — `B::SV` missing `SV` method (1 test, 1 subtest fails) + +**Symptom:** `Can't locate object method "SV" via package "B::SV"` at +`Test2/Util/Stash.pm` line 117. + +**Root cause:** `Test2::Util::Stash::get_symbol()` calls `B::svref_2object(\*glob)->SV`. +PerlOnJava's `B::svref_2object()` returns `B::SV` for GLOB refs (should return `B::GV`), +and `B::SV` has no `SV` method. + +**Three things missing from `src/main/perl/lib/B.pm`:** + +1. **`svref_2object` doesn't detect GLOB refs** — should return `B::GV`: +```perl +# In svref_2object, add before the SCALAR check: +if ($rtype eq 'GLOB') { + my $name = *{$ref}{NAME} // ''; + my $pkg = *{$ref}{PACKAGE} // 'main'; + my $gv = B::GV->new($name, $pkg); + $gv->{ref} = $ref; # store glob ref for SV access + return $gv; +} +``` + +2. **`B::GV` needs `SV` method** — return scalar slot of glob: +```perl +package B::GV; +sub SV { + my $self = shift; + my $glob = $self->{ref}; + if (defined $glob) { + local $@; + my $sv_val = eval { ${*{$glob}} }; + if (!$@ && defined $sv_val) { + return B::SV->new(\${*{$glob}}); + } + } + return B::SPECIAL->new(0); # 0 = index for 'Nullsv' +} +``` + +3. **`B::SPECIAL` class needed** — must NOT inherit from `B::SV`: +```perl +package B::SPECIAL; +sub new { my ($class, $index) = @_; bless \$index, $class } +``` + +--- + +#### 7.2.8 `unit-files-are-the-same.t` — `<$var/*.t>` glob not interpolating (1 test, 0 subtests) + +**Symptom:** "No tests run!" — exit 255. + +**Root cause:** The test uses `<$RealBin/*.t>` to find test files.

Also fix ArgumentParser.java for -S flag. Priority 2: Diamond operator <$var/*.t> now interpolates variables using double-quote semantics (StringParser, EmitOperator, CompileOperator). Both JVM and bytecode backends updated to correctly distinguish readline vs glob when operand is not a simple StringNode. Priority 3: B::svref_2object now detects GLOB refs and returns B::GV. Added B::GV::SV method and B::SPECIAL class for Test2::Util::Stash. Priority 4A: Stat.java and FileTestOperator.java now unwrap DupIOHandle and BorrowedIOHandle (not just LayeredIOHandle) to reach the underlying CustomFileChannel for stat/file-test ops. Priority 4B: RuntimeGlob.dynamicSaveState/Restore now saves and restores selectedHandle, and initializes new glob with stub IO when the old glob was the selected handle. This ensures print follows localized STDOUT during local(*STDOUT).

Glock" Date: Tue, 7 Apr 2026 20:39:26 +0200 Subject: [PATCH 6/6] fix: backslash prototype precedence for tied/tie/untie with glob arguments PerlOnJava parsed `tied *STDOUT && expr` as `tied(*STDOUT && expr)` instead of `(tied *STDOUT) && expr`. This caused Capture::Tiny to skip its `local(*STDOUT)` call when STDOUT was tied by Test2::Plugin::IOEvents, corrupting the selectedHandle and breaking print output capture. The fix adds parseBackslashArgWithComma() which parses backslash prototype arguments at named-unary precedence (level 15, same as isa) instead of comma precedence (level 5). This matches Perl 5 behavior where comparison/logical operators are NOT consumed but arithmetic operators ARE consumed. App::perlbrew: 65/73 -> 66/73 tests pass.
