vam-google	564dc771dc	Return PyInfo provider with imports from _gen rules and pass that as deps in py_library. This allows hiding _virtual_imports include path from the surface.	5 years ago
vam	461c053c37	[bazel][python] Support _virtual_imports input for py_proto_library and py_grpc_library rules `proto_library` targets are used as deps for `py_proto_library` and `py_grpc_library` rules. The `proto_library` targets can be configured using `import_prefix` and/or `strip_import_prefix` (which essentially move original location of the proto file and, as result, affects import path within proto files themselves and in the generated language-specific stubs). The biggest question to answer when generating stubs from moved protos is where to put result (this decision affects all downstream rules as well, because the location of file affects its import path). This PR tries to follow same logic as the native `cc_proto_library` (created and maintained by Bazel team). For example, if we have `firestore.proto` file, which is located under `google/firestore/v1beta1` Bazel package and want to move it under `google/cloud/firestore_v1beta1/proto` (this is axactly what happens in googleapis repository), it can be configured the following way: ```bzl proto_library( name = "firestore_moved_proto", srcs = ["firestore.proto"], import_prefix = "google/cloud/firestore_v1beta1/proto", strip_import_prefix = "google/firestore/v1beta1", ) ``` The rule above will first generate virtual `.proto` files (under new location) and only after that generate a binary descriptor from them. Specifically it will generate the following "virtual" file under `_virtual_imports` subdirectory of same package: ``` bazel-bin/google/firestore/v1beta1/_virtual_imports/firestore_moved_proto/google/cloud/firestore_v1beta1/proto/common.proto ``` When supplied to `cc_proto_library`, like the following: ```bzl cc_proto_library( name = "firestore_moved_cc_proto", deps = ["firestore_moved_proto"], ) ``` The rule will generate .cc and .h files like the following: ``` bazel-bin/google/firestore/v1beta1/_virtual_imports/firestore_moved_proto/google/cloud/firestore_v1beta1/proto/firestore.pb.h bazel-bin/google/firestore/v1beta1/_virtual_imports/firestore_moved_proto/google/cloud/firestore_v1beta1/proto/firestore.pb.cc ``` Notice, that each generated `.cc` and `.h` file is prefixed with `_virtual_imports/<name_of_proto_library_target>`. The python rules try to do same thing, so for the following py_proto_library rule: ```bzl py_proto_library( name = "firestore_moved_py_proto", deps = [":firestore_moved_proto"], ) ``` It wil generate the following file: ``` bazel-bin/google/firestore/v1beta1/_virtual_imports/firestore_moved_proto/google/cloud/firestore_v1beta1/proto/firestore_pb2.py ``` I.e in same path as cc_proto_library. This all woks, but an annoying part is that to use the generated library in some other py_library, in needs to specify the "_virtual_imports/proto_target" path as its "includes" parameter (and I can't make it better than that). Another option would be to skeep the `_virtual_imports/<name_of_proto_library_target>` the suffix for the generated python stubs, which will make the path look like the following: ``` bazel-bin/google/firestore/v1beta1/google/cloud/firestore_v1beta1/proto/firestore_pb2.py ``` That will make using generated stubs simpler and cleaner (no need to specify imports argument), but it will make it inconsistent with the other rules (like cc_proto_library) and also more susseptible to naming conflicts (if there is already something under the generated path).	5 years ago
Richard Belleville	8ce740cfe0	Switch py_proto_library from using src to deps to conform with google3	5 years ago
Richard Belleville	835b3d3293	Copyright.	5 years ago
Richard Belleville	7b2c8c27b0	Separate py_grpc_library and py_proto_library. By popular demand, we'll now be offering separate py_grpc_library and py_proto_library targets sharing the same interface as within google3. This change necessitated some modifications to how we pull in our own Python-level dependencies and how we make those available to those pulling in our project via Bazel. There is now a grpc_python_deps() Bazel workspace rule that pulls in the appropriate dependencies, which should be called from the client project's WORKSPACE file. A test has been added to the bazel/test/ directory to verify that this behavior works as intended. It's worth noting that the protobuf repository's usage of Starlark bind() caused a great deal of trouble in ensuring that we could also pull in six. This change also required a change in the way generated proto code is imported in the channelz and health-check modules, as well as in their associated tests. We were importing them two different ways, each relative. This resulted in two different module objects being imported into the process, which were incompatible. I am not sure exactly what caused this behavior to begin, as this should have been possible before this PR. As a workaround, I am simply trying two different absolute imports and using the one that works. This should function both inside and outside of Bazel environments.	5 years ago
