What

Export the versioned std::__sce_v2 locale::classic, locale::empty, locale::global, locale::_Setgloballocale, _Locimp::_New_Locimp(bool), _Locimp::_Clocptr, _sceLibcLocinfo, and the _Locinfo constructor and _Addcats that take a category, from libc.

The behavior comes from the libc.prx bundled with PPSA03671 v01.001.005 (J03848509, SHA-256 483961e086b8a1fffa8138b3c0badf798987fb5f35ec908d828946408be2d8a6).

They build on main's versioned locale, which shares the unversioned 0x30-byte _Locimp and has the classic locale ready from the start. As in the module:

• classic() returns a static locale that holds the classic _Locimp, and _Clocptr points at that _Locimp;
• empty() and _New_Locimp(bool) build a _Locimp with one reference, no facets, category 0 and the name *; empty() makes it transparent and _New_Locimp takes the flag;
• _Setgloballocale stores the global _Locimp, and _Getgloballocale and _Init(bool) now return that global instead of the classic one, so they follow it once it changes; _Init still takes a reference when its flag is set;
• global() returns the previous global through _Init(true). When the new locale differs, it releases the old global's reference, installs and retains the new one, and calls setlocale with its name for each category in its mask, or once for all six;
• _sceLibcLocinfo throws runtime_error("bad locale name") unless the name is "" or "C". The two _Locinfo calls ignore the category, check the name the same way, and store setlocale(LC_ALL, nullptr); the constructor first stores the current name, and both store the classic name only after the check.

_Locimp_ctor and _Locimp_dtor are left for a follow-up, since they need reference counting in _Locimp_Addfac and _New_Locimp(const _Locimp&), which main does not do yet. A new debt entry records what differs here. The existing versioned locale entry now says _Init and _Getgloballocale return the global locale.

Tested

Windows x86-64, WinLibs GCC 15.2.0, Release, BUILD_TESTING=ON, main d893997f1a6. Exact tested commit: d18e1c71325.

• Built libc, libkernel, their NID-patched production libraries and the related tests. The new guest_sce_v2_locale_basics passes, along with guest_sce_v2_locale, guest_locale and guest_sce_v2_exceptions.

• The NID-patched libc exports all 9 NIDs above.

• The new test checks:

  • that classic(), _Clocptr, _Getgloballocale and _Init agree on the classic _Locimp;
  • the fields of the _Locimp that empty() and both _New_Locimp(bool) build;
  • the references global() takes and releases when it installs a locale, keeps the same one and restores the classic one;
  • that _Setgloballocale takes no reference, and that a null locale throws and keeps the global;
  • every field the _Locinfo calls write, for accepted names and four categories, and the bad locale name exception and the fields left for six rejected names.

• The original functions were loaded from the bundled module with their relocations applied. Their imports were bound by NID to this branch's libc and libkernel. The module's heap is not set up outside a console process, so its allocation calls were redirected to the host's. Its _Xruntime_error and this branch's were both redirected to one recorder, so each side's rejections were compared by message.

• Side by side with the patched production library, over two seeds with 20,000 trials each:

  • 60,000 calls per seed of the three name checks, with random names and categories (about 15,000 accepted, 45,000 rejected), compared by outcome and every field written;
  • the _Locimp that empty() and _New_Locimp build, compared field by field;
  • that classic(), _Clocptr, _Getgloballocale and _Init agree after the module's _Init built its classic locale;
  • 20,000 random global, _Setgloballocale, _Init and _Getgloballocale calls over the classic locale and six other _Locimps, with about 8,000 switches, of which about 3,300 global() calls changed the global. Each step compared the returned locale, the global and every reference count except the classic one's, which differs by design.

  No comparison differed.

• Negative control: five lines were altered one at a time:

  • the empty name was rejected;
  • global() kept the old global's reference;
  • empty() built an opaque _Locimp;
  • _Init(true) took no reference;
  • the _Locinfo constructor stored the classic name before checking the name.

  The new CTest failed on each, and the side-by-side run reported differences each time. The source was then restored byte for byte (SHA-256 checked) and rebuilt, and the test and side-by-side run passed again.

• Code conventions and git diff --check pass.

• tools/pr_overlap.py read 1,863 open PRs at the tested commit and reports no overlap. It keeps exit 2 for 38 branches that already conflict with main. Merging each of the 38 with this branch and with main using git merge-tree gives the same conflict blocks, except in docs/dev/debt/libc.md for feat(aot): consolidate native ARM64 compiler, runtime and consumers #5021, fix(libc): follow a Windows symbolic link before .. in a guest path #9371, feat(libc): add the std::__sce_v2 thread start, timed wait, clock and processor count calls #9447 and feat(libc): add std::__sce_v2::_Random_device, _Fiopen and setw #9526: their conflict block there already spans the end of the functional section, which holds the versioned locale entry this PR corrects, so the corrected line and the new entry next to it land inside it. The new entry adds no conflict with any of the 141 open PRs that touch that file. fix(relinker): match AppContent utility import to provider #13486 names the unversioned std::locale::_Setgloballocale in libSceLibcInternal, not these exports. No open PR adds these names or NIDs. The branch also merges cleanly with fix(libc): preserve Dinkumware zero signs when no conversion occurs #14595, feat(libc): export the std::__sce_v2 extended-precision helpers #15336, feat(libc): export the std::__sce_v2 multiprecision helpers #15471, feat(libc): export the std::__sce_v2 _Poly and _XLgamma helpers #15484, feat(libc): export the std::__sce_v2 _Xtime_diff_to_millis2 helper #15490, feat(libc): export the std::__sce_v2 _Exp and _FExp helpers #15501, feat(libc): export the std::__sce_v2 _Pmsw, _FPmsw and _LPmsw helpers #15519, feat(libc): throw std::bad_cast and the std::__sce_v2 bad_any_cast, format_error and future_error #15552, feat(libc): forward the std::atomic wait and notify helpers to libkernel #15561, feat(libc): count the std::__sce_v2 _Winit and ios_base::Init initializations #15602, feat(libc): export the std::__sce_v2 floating-point constants #15614, fix(libc): store the std::__sce_v2 _Throw_Cpp_error value in the first code word #15667, feat(libc): export the std::__sce_v2 _Stollx, _Stoullx, _Stolx and _Stoulx parsers #15683, feat(libc): export std::_Throw_bad_any_cast and std::_Throw_bad_node_access #15791, feat(libc): export the std::error_category complete and deleting destructors #15796, feat(libc): export the std::__sce_v2 resetiosflags, setiosflags, setbase and setprecision manipulators #15809, feat(libc): export the std::__sce_v2 _Timespec64_get_sys and _Timespec64_diff_to_ts clock helpers #15834, feat(libc): export the std::__sce_v2 at-thread-exit registry calls #15879, feat(libc): export the remaining std::__sce_v2 facet ids and ios_base _Sync and _Index #15923 and feat(libc): export the std::__sce_v2 clog, wclog and standard stream pointers #16083.
