Remove ICodedInputStream and ICodedOutputStream, and rewrite CodedInputStream and CodedOutputStream to be specific to the binary format. If we want to support text-based formats, that can be a whole different serialization mechanism.
This makes repeated fields really awkward at the moment - but when we reimplement RepeatedField<T> to be backed by an array, we can cast the array directly...
Cache a reference to Encoding.UTF8 - the property access is (rather surprisingly) significant.
Additionally, when we detect that the string is all ASCII (due to the computed length in bytes being the length in characters), we can perform the encoding very efficiently ourselves.
We still have some protos which aren't generated how we want them to be:
- Until we have an option to specify the "umbrella" class, DescriptorProtoFile
will be broken. (The change of name here affects the reflection descriptor,
which accounts for most of the change. That's easier than trying to work out
exactly which occurrences of Descriptor need changing though.)
- That change affects UnittestCustomOptions
- Issue #307 breaks Unittest.cs
After this commit, we don't have the record of the fixups in the files themselves
any more, but one centralized record in the shell script.
To my surprise, executing generate_protos.sh used the version of Bash installed with Git for Windows by default.
After a few modifications to detect the most appropriate protoc to use, this worked pretty simply.
This change also:
- adds generation of the address book tutorial proto,
- fixes the addressbook.proto to specify proto2 explicitly (to avoid a warning from protoc; I don't think we want warnings...)
- fixes the addressbook.proto C# namespace (which I thought I'd done before, but apparently hadn't)
- includes the regenerated UnittestCustomOptions.cs apart from the DescriptorProtoFIle => Descriptor change
This is the start of establishing a C# namespace of "Google.ProtocolBuffers.TestProtos.Proto3" for proto3-syntax protos.
We could optionally split the directory structure as well into Proto2 and Proto3 for clarity.
This includes the NUnit test adapter which allows NUnit tests to be run under VS without any extra plugins.
Unfortunate the compatibility tests using the abstract test fixture class show up as "external" tests, and aren't well presented - but they do run.
All referring projects are now .NET 4 client rather than .NET 3.5.
This commit also fixes up the ProtoBench app, which I'd neglected in previous commits. (Disentangling the two sets of changes would be time-consuming.)
Move to a single solution file containing all of the C# projects, but no other solution folders - it's easier to edit those files outside VS than keep adding and removing them from the project.
The AddressBook protos have been regenerated (with a change to the example proto which I haven't included in this change - I'll wait for us to decide exactly what we're doing with namespaces before changing protos outside the csharp directory.
Note that now we've got Addressbook.cs which contains AddressBook and Addressbook classes. It's bad enough that we've got a class called AddressBook within a namespace of AddressBook (hard to get away from) but having things vary just by case is nasty.
This is more evidence that an option for renaming the file and descriptor class would be welcome. (A single option can probably handle both.)
This could potentially be added back in later, but its use is limited and it's a pain in terms of support in PCL environments.
One use that has been highlighted is passing objects between AppDomains; we'd recommend passing a byte array explicitly and reparsing on the other side.
1) Project files for different configurations - we're going to look at all this again, ideally to just have a single PCL-compatible build
2) ProtoGen - the C++ generator is now the only one we care about
3) Proto files - these are mostly duplicates (or older versions) of the ones in the common directories
(Having regenerated descriptor.proto relative to src, the earlier commented-out code checking that dependencies match may now be okay to uncomment again. Will experiment in later CLs.)
This commit includes changes to the C#-specific protos, and rebuilt versions of the "stock" protos.
The stock protos have been locally updated to have a specific C# namespace, but this is expected to change soon, so hasn't been committed.
Four areas are currently not tested:
1) Serialization - we may restore this at some point, possibly optionally.
2) Services - currently nothing is generated for this; will need to see how it interacts with GRPC
3) Fields beginning with _{digit} - see https://github.com/google/protobuf/issues/308
4) Fields with names which conflict with the declaring type in nasty ways - see https://github.com/google/protobuf/issues/309
1) Remove CSharpOptions
2) A new version of DescriptorProtoFile (with manual changes from codegen - it would otherwise be Descriptor.cs)
3) Turn off CLS compliance (which we'll remove from the codebase entirely; I don't think it's actually relevant these days)
4) Add "public imports" to FileDescriptor, with code broadly copied from the Java codebase.
Lots more changes to commit before it will build and tests run, but one step at a time...
