+Subject: [PATCH] don't build grpcio in install_all_python_modules.sh
+
+We run this script in CIBW_TEST_COMMAND to install grpcio's other Python
+packages and their test dependencies, but we don't want it to reinstall
+grpcio itself from source - we want the test environment to use the
+wheel built (and about to be distributed) in this same cibuildwheel
+invocation.
+
+This is a rework of the older patches from Mark to handle upstream's
+change to using pyproject.toml instead of setup.py.

+Subject: [PATCH] grpcio_tests: anchor GatherProto's proto paths to GRPC_STEM
+
+commands.py's GRPC_PROTO_STEM/PROTO_STEM/PYTHON_PROTO_TOP_LEVEL were made
+cwd-relative by the pyproject.toml migration (#40833), which is fine for
+the new PEP517 build path (BuildPackageProtos), but breaks the legacy
+"preprocess" command (GatherProto) used by
+tools/distrib/install_all_python_modules.sh. That script pushd's into
+src/python/grpcio_tests before invoking `setup.py preprocess`, so the
+relative path "src/proto" no longer resolves:
+
+    running preprocess
+    error: [Errno 2] No such file or directory: 'src/proto'

+From: RISE python-wheels <noreply@riseproject.dev>
+Subject: [PATCH] fix per-package command cwd-relative path regression from #40833
+
+Same regression as the grpcio_tests/commands.py GatherProto fix
+(0003-fix-GatherProto-cwd-relative-path-regression.patch): the
+pyproject.toml migration (#40833) made these per-package "preprocess"/
+"build_package_protos" setuptools Command classes cwd-relative instead
+of anchored to GRPC_ROOT_ABS_PATH/ROOT_DIR (both already computed
+absolute in each file). install_all_python_modules.sh pushd's into each
+package's own directory before running these commands, so the relative
+paths ("src/proto/...", "./LICENSE", ROOT_REL_DIR) don't resolve there -
+symptoms range from a silently-skipped proto copy to
+grpc_tools.command.build_package_protos() finding zero .proto files and
+silently emitting no *_pb2.py, e.g.:
+
+    ImportError: cannot import name 'health_pb2' from 'grpc_health.v1'
+
+Fixes the same way as 0003: revert each file's constants/run() bodies to
+use the already-computed absolute ROOT_DIR/GRPC_ROOT_ABS_PATH instead of
+the relative ROOT_REL_DIR, matching pre-#40833 behavior. Affects every
+per-package command module install_all_python_modules.sh's PACKAGES loop
+touches that generates protos or copies LICENSE: grpcio_channelz,
+grpcio_health_checking, grpcio_reflection, grpcio_status, grpcio_testing.
+(grpcio_tests/commands.py is 0003; grpcio/commands.py and grpcio_csds/
+grpcio_admin/grpcio_csm_observability are unaffected - the former is
+invoked from repo root, the latter three carry no such module.)

+tests.unit._sanity._sanity_test.SanityTest.testTestsJsonUpToDate compares
+the checked-in tests.json against the test classes discovered at runtime
+and fails if they don't match exactly. Upstream's tests.json for the
+v1.80.0 tag was never regenerated after tests.interop._secure_intraop_test
+gained SecureInteropWithSyncPrivateKeyOffloadingTest and
+SecureInteropWithAsyncPrivateKeyOffloadingTest, and after
+tests.interop.security_test.SecurityTest was added - all three classes
+exist in the shipped test files but are absent from tests.json. Confirmed
+against a plain checkout (no riscv64-specific behavior involved).
+
+Skip rather than hand-maintain a tests.json diff that would need updating
+on every version bump if upstream keeps adding tests without regenerating
+this file.
