reline-0.1.3 requires ruby version >= 2.5, which is incompatible with the current version, ruby 2.4.9p362
* WIP.
* WIP.
* Builds and runs. Tests need to be updated to test presence.
* Ruby: proto3 presence is passing all tests.
* Fixed a bug where empty messages has the wrong oneof count.
Previously if you assigned 'nil' to a submessage in proto2
the field would be set to 'nil' but would still have its hasbit
set. This was a clear bug so I'm fixing it outright, even though
it is an observable behavior change.
* Add a test suite for ruby 2.7
* Call BigDecimal() instead of BigDecimal.new()
BigDecimal.new was deprecated in ruby 2.6
* Switch FrozenError expectation to a matcher
The error message for FrozenError changed to include more information
about the mutated object. Switch from an exact match to an aproximate
match (equal => match). This does not change the prefix.
* We can safely ignore newest array methods from ruby 2.7
* Build extensions for Ruby 2.7
* Try installing bundler 2.x
* Try bumping rake-compiler-dock
* Use standard RCD images
* Avoid 'rake cross native' with rake-compiler-dock
* Use Ruby 2.5 for building Ruby <= 2.6
* Use rake-compiler 1.1.0
* Specify target
* Don't update Ruby test image for now
This patch has almost no change in behaviour where users have not
patched the implementation of new on either a specific proto object
class, or `Google::Protobuf::MessageExts::ClassMethods`. The default
implementation of `new`, and `rb_class_new_instance` have the same
behaviour.
By default when we call `new` on a class in Ruby, it goes to the `Class`
class's implementation:
```ruby
class Foo
end
>> Foo.method(:new).owner
=> Class
```
the `Class` implementation of `new` is (pseudocode, it's actually in c):
```ruby
class Class
def new(*args, &blk)
instance = alloc
instance.initialize(*args, &blk)
instance
end
end
```
`rb_class_new_instance` does the same thing, it calls down to
[`rb_class_s_new`](https://github.com/ruby/ruby/blob/v2_5_5/object.c#L2147),
which calls `rb_class_alloc`, then `rb_obj_call_init`.
`rb_funcall` is a variadic c function for calling a ruby method on an object,
it takes:
* A `VALUE` on to which the method should be called
* An `ID` which should be an ID of a method, usually created with `rb_intern`,
to get an ID from a string
* An integer, the number of arguments calling the method with,
* A number of `VALUE`s, to send to the method call.
`rb_funcall` is the same as calling a method directly in Ruby, and will perform
ancestor chain respecting method lookup.
This means that in C extensions, if nobody has defined the `new` method on any
classes or modules in a class's inheritance chain calling
`rb_class_new_instance` is the same as calling `rb_funcall(klass,
rb_intern("new"))`, *however* this removes the ability for users to define or
monkey patch their own constructors in to the objects created by the C
extension.
In Ads, we define [`new`](https://git.io/JvFC9) on
`Google::Protobuf::MessageExts::ClassMethods` to allow us to insert a
monkeypatch which makes it possible to assign primitive values to wrapper type
fields (e.g. Google::Protobuf::StringValue). The monkeypatch we apply works for
objects that we create for the user via the `new` method. Before this commit,
however, the patch does not work for the `decode` method, for the reasons
outlined above. Before this commit, protobuf uses `rb_class_new_instance`.
After this commit, we use `rb_funcall(klass, rb_intern("new"), 0);` to construct
protobuf objects during decoding. While I haven't measured it this will have
a very minor performance impact for decoding (`rb_funcall` will have to go to the
method cache, which `rb_class_new_instance` will not). This does however do
the "more rubyish" thing of respecting the protobuf object's inheritance chain
to construct them during decoding.
I have run both Ads and Cloud's test suites for Ruby libraries against this
patch, as well as the protobuf Ruby gem's test suite locally.
* Set execute bit on files if and only if they begin with (#!).
Git only tracks the 'x' (executable) bit on each file. Prior to this
CL, our files were a random mix of executable and non-executable.
This change imposes some order by making files executable if and only
if they have shebang (#!) lines at the beginning.
We don't have any executable binaries checked into the repo, so
we shouldn't need to worry about that case.
* Added fix_permissions.sh script to set +x iff a file begins with (#!).
* Add failing tests for issues with wrapped values where the value is the default
* Add test for wrapped values without a value set
* Bugfix for wrapper types with default values.
The previous optimizations for wrapper types had a bug that prevented
wrappers from registering as "present" if the "value" field was not
present on the wire.
In practice the "value" field will not be serialized when it is zero,
according to proto3 semantics, but due to the optimization this
prevented it from creating a new object to represent the presence of the
field.
The fix is to ensure that if the wrapper message is present on the wire,
we always initialize its value to zero.

The only case that doesn't work is decoding a wrapper type from JSON
at the top level. This doesn't make sense and probably no users do it
I changed it to throw.
`OneOfDescriptor_each` is registered as a Ruby method which takes zero
parameters, which means it should take one argument.
When Ruby invokes `OneOfDescriptor_each`, it calls it with one parameter
only, which is one less than what `OneOfDescriptor_each` takes before
this commit. Calling a function with the wrong number of argument is
technically undefined behavior.
