* Bump internals version * Prevent internals destruction before all pybind11 types are destroyed * Use Py_XINCREF and Py_XDECREF * Hold GIL before decref * Use weakrefs * Remove unused code * Move code location * Move code location * Move code location * Try add tests * Fix PYTHONPATH * Fix PYTHONPATH * Skip tests for subprocess * Revert to leak internals * Revert to leak internals * Revert "Revert to leak internals" This reverts commitc5ec1cf886. This reverts commit72c2e0aa9b. * Revert internals version bump * Reapply to leak internals This reverts commit8f25a254e8. * Add re-entrancy detection for internals creation Prevent re-creation of internals after destruction during interpreter shutdown. If pybind11 code runs after internals have been destroyed, fail early with a clear error message instead of silently creating new empty internals that would cause type lookup failures. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Fix C++11/C++14 support * Add lock under multiple interpreters * Try fix tests * Try fix tests * Try fix tests * Update comments and assertion messages * Update comments and assertion messages * Update comments * Update lock scope * Use original pointer type for Windows * Change hard error to warning * Update lock scope * Update lock scope to resolve deadlock * Remove scope release of GIL * Update comments * Lock pp on reset * Mark content created after assignment * Update comments * Simplify implementation * Update lock scope when delete unique_ptr --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
