            maven multi-module project with two versions of protobuf
            Asked 2021-Jun-15 at 21:40

            We have a multi-module maven project. One of the modules has a bunch of .proto files, which we compile to java files. Pretty much every other module depends on this module. Most of them use Protobuf 2.4, but one needs to use 2.5.

            Is there any nice way to do this? (The not nice way is to edit the pom file to say "2.5", build a jar, manually copy that jar to wherever we need it, and then change the pom file back to 2.4.)

            Never used protobuf, but, as I understand it's a plugin that generate stuff.

            So I'm gonna give you generic pointer hoping it will help. I think you should either try to make 2 jar with different classifier from a single module, see https://maven.apache.org/plugins/maven-jar-plugin/examples/attached-jar.html For example classifier proto2.4 and proto2.5 then you can add the classifier when you define the dependency to that module.

            Other option I see is having 2 modules, the real one, you have now, and another one for 2.5 Generate a zip from the main one and the second module would be empty but have a dependency on the generated zip, unzip it and then compile with the plugin config for 2.5 Slower at execution, a bit dirtier imho, but can be needed if for example you need more customization than just the version.

            MySQL stored procedures do have all the necessary programming constructs to do this, so theoretically it is possible. However, it will involve quite a bit of programming and is probably not worth doing on database side.

            However, here is the rough sketch of what the stored procedures would have to do. Refer to Protobuf encoding documentation for details.

            1. Create a stored procedure read_varint() that will read the first varint from a blob, and returns it as integer and the remaining blob.
            2. Create a stored procedure decode_point() that repeatedly calls read_varint() to take a tag, then calls read_varint() to read field data and assigns it to variable based on tag number.
            3. Create similar decode_timestamp() for the built-in google.protobuf.Timestamp datatype and call it from decode_point() for the timestamp field.
            4. Create a stored procedure decode_entry() that repeatedly calls read_varint() to take a tag, and either decodes time directly or calls decode_point(), depending on the tag value.
            5. Extend all these procedures to skip fields with unknown tag numbers.

            Interestingly, your message types only have varint fields. So at the bare minimum, you could just call read_varint() repeatedly to get all the varints to a list. Then each field is always at a specific index. However, I don't recommend this, because it wouldn't be possible to extend it to handle future fields of different types.

            The protoc generation should have produced a method called GetMetadata for both types. You can check if the incoming message implements an interface using a type assertion (see the tour of go for more details), then call that method to get the metadata.

            This is what I meant with this comment

            though boost::system::system_error could invite issues back

            The trouble is, error categories are global singleton instances, with object identity (i.e. compared for equality by their address).

            You'r ending up with multiple instances in multiple modules. The usual solution is to

            • dynamically link to Boost System, so all libraries use the same copy (this does however sometimes run into initialization order issues)
            • if that doesn't solve it, make sure all modules actually load the same library (version?)
            • In recent boosts I think there's the option to build Boost System completely header-only. This may or may not involve new-fangled C++14 inline, I haven't checked.

            If all else fails, do your own translation. There's related issues that might give you ideas:

            Is it normal or expected to compare only errorCode.value() against enums?

            No it is not. According to some sources Boost as well as standard library promise to map generic error category to errc which is standard - so you could do that, but you still have to figure out whether that is the category, so doesn't help your scenario.

            You can install using 'pip install protobuf' or download it from GitHub, PyPI.
            You can use protobuf like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
