There are corner cases where MessageDescriptor.{ClrType,Parser} will return null, and these are now documented. However, normally they *should* be implemented, even for descriptors of for dynamic messages. Ditto FieldDescriptor.Accessor.
We'll still need a fair amount of work to implement dynamic messages, but this change means that the public API will be remain intact.
Additionally, this change starts making use of C# 6 features in the files that it touches. This is far from exhaustive, and later PRs will have more.
Generated code changes coming in the next commit.
Generated code coming in next commit - in a subsequent PR I want to do a bit of renaming and redocumenting around this, in anticipation of DynamicMessage.
In the old flow, any 2 char prefix in the expected file was still generating a
warning about being a poor prefix. Now we check the expected file first, so
anything expected is let through.
Instead of having a Proto nested namespace to avoid conflicts between the descriptor-holding static class and message classes, just append "Reflection" to the name.
Generated code changes (and corresponding manual changes) in following commit.
1. mathlimits.h must be included before the inclusion of cmath (which
gtest/gtest.h seems to include).
2. hash function for StringPiece doesn't work.

VC++ up to VS 2015 RTM does not require explicit storage allocation for
static const integers declared in classes. VS 2015 Update 1 requires
these storage definitions in some cases. It's unclear exactly what
cases - simple tests work with and without the explicit storage
allocation.
Many previous versions of VC++ have theoretically *allowed* a
definition to supply storage, but tests on VC++ 2013 show that this
doesn't actually work correctly - it leads to duplicate definition
errors in Chromium. So, the change is scoped to VS 2015 only.
This change also updates the generated files to match the new generator.
TL;DR - this change is necessary in order for Chromium to build with
VS 2015 Update 1.
This could be tidied up significantly, and at some point we will want to parse the markdown and generate more appropriate XML - but this is definitely better than nothing.
Generated code changes coming in next commit.
There are now summaries for:
- The Types nested class (which holds nested types)
- The file descriptor class for each proto
- The enum generated for each oneof
(Also fixed two typos.)

Xcode raises warning that says "'BYTE_SIZE' macro redefined".
The original 'BYTE_SIZE' macro definition is here, for example:
'/Applications/Xcode/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/mach/vm_param.h'
This introduces a new C# option, base_namespace.
If the option is not specified, the behaviour is as before: no directories are generated.
If the option *is* specified, all C# namespaces must be relative to the base namespace, and the directories are generated relative to that namespace.
Example:
- Any.proto declares csharp_namespace = "Google.Protobuf.WellKnownTypes"
- We build with --csharp_out=Google.Protobuf --csharp_opt=base_namespace=Google.Protobuf
- The Any.cs file is generated in Google.Protobuf/WellKnownTypes (where it currently lives)
We need a change to descriptor.proto before this will all work (it wasn't in the right C# namespace) but that needs the other descriptors to be regenerated too. See next commit...
When the user passed in a block which was smaller than the Block
structure, this code would blow past the end of the memory and
crash. Check for that condition.
These are banned by the Google style guide, and Chromium has a hard
no-new-static-initializers policy preventing updating to a new version of
libprotobuf unless this is resolved. This is the first such change, I'll need
to make at least one more in the future.
Luckily, the protobuf source tree already has an alternative to static
initializers in once.h; use that machinery instead.
I defined everything in the .cc file in a blob to replace the old implementation
rather than matching the .h layout precisely; let me know if a different
ordering is preferred. I also eliminated the macro that used to be used here as
spelling everything out only takes one additional line, and the macro didn't
actually handle all details of using a particular member variable, just the
declaration, so it felt a bit error-prone.
It's not enough to check for C++11 language support, as it's possible for
projects to enable C++11 language and library features independently (e.g.
Chromium currently does this). Instead, explicitly check the library version to
see if it is recent enough to include unordered_{map|set}.
This came up because Chromium downstream modifies the lite library in a way that
requires this function, but I'm upstreaming it because based on the comments in
repeated_field.h, this ought to allow resolution of an existing hack.
I don't know enough about the protobuf code to feel confident trying to resolve
this hack myself, so I've merely updated the TODO comments.
When trying to compile the protobuf code as a DLL, and then compile other DLLs
with generated .pb.cc/h files that reference
InternalMetadataWithArena::InternalMetadataWithArena(Arena*), MSVC gives an
"unresolved external symbol" error. This seems to be due to the function being
simultaneously exported and inline. Moving it out-of-line fixes things.
There are other functions exported and inline as well but de-inlining them
doesn't seem to be necessary to get the build working, and I'd rather de-inline
as few functions as possible.
port.h #includes various headers in order to define byteswap functions, but it
currently does so from inside the google::protobuf namespace. This can cause
bizarre symbol conflicts and other build errors as these headers' contents are
then included inside this namespace.
Instead, #include the relevant headers above the namespace declarations.
