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

Lukacs T. Berki	e2ba3aa070	Update C++ code generation to work with Bazel 0.29 . The above Bazel version changes proto compilation slightly: some proto files are put into a `_virtual_imports` directory and thus `_get_include_directory` needs to be updated accordingly. Ideally, it would use instead the `ProtoInfo` provider to tease out the proto import directories, but that's a bit more intrusive change.	5 years ago

Richard Belleville	05f37c8143	Remove dependency on pubref/rules_proto. This commit resolves #18331. This commit resolves #18256. This commit resolves... another TODO that apparently didn't have an associated github issue. We swap out pubref's implementation of py_proto_library with our own, which more closely mirrors the interface of the internal py_proto_library, taking the descriptor file output of a proto_library rule as input. One minor change in behavior was introduced for simplicity. When a py_proto_library depends on a proto_library with a source proto file in a subdirectory of the bazel package, the import module of the resultant python library will reflect the package, not the full directory of the proto file, including both the bazel package and the subdirectories, as pubref did previously. This behavior also more closely mirrors google internal behavior. This commit also introduces a slightly more stringent bazel format script. Buildifier on its own will not take care of long lines, but by running yapf first, we end up with a more legible file. At the moment, there is no sanity check associated with this formatter.	6 years ago
