C++ coroutines: Getting rid of our reference count

by Raymond Chen

From the article:

In an earlier installment, we simplified our promise_ptr type, and one of the consequences of this is that there are no remaining caller of increment_ref. This means that we don’t need a reference count at all and can rely on the state changes to tell us when to destroy the promise: When the awaiter has obtained the result or, or when the coroutine completes and discovers that the awaiter has abandoned its effort to obtain the result...

C++ coroutines: Getting rid of our mutex

by Raymond Chen

From the article:

Our coroutine implementation uses a mutex to guard against the race condition where a coroutine completes at the same time another thread tries to wait for its completion. The race condition in question is this one...

C++ coroutines: Making it impossible to co_await a task twice

by Raymond Chen

From the article:

One design limitation of the coroutine implementation we’ve been developing is that it supports only one co_await client. We enforce this with a runtime assertion, but what if the problem occurs in the release build?

C++ coroutines: Tradeoffs of making the promise be the shared state--Raymond Chen

C++ coroutines: Tradeoffs of making the promise be the shared state

by Raymond Chen

From the article:

Last time, we traced the lifetimes of the objects involved in the coroutine function. Now we can look at some of the tradeoffs we’ve made in our design and see how the decisions are intertwined...

Automatically Resuming a Job with Coroutines on a Separate Thread--Rainer Grimm

Automatically Resuming a Job with Coroutines on a Separate Thread

by Rainer Grimm

From the article:

In my last post "Starting Jobs with Coroutines", I applied co_await to start a job. In this post, I improve the workflow and automatically resume a job if necessary. In my final step, I resume the job on a separate thread...

C++ coroutines: The lifetime of objects involved in the coroutine function

by Raymond Chen

From the article:

We finally hooked up the last missing piece of our coroutine promise implementation. Before we can look at the tradeoffs we’ve made, let’s step back and follow the lifetime of the various objects involved in the coroutine function.

C++ coroutines: Managing the reference count of the coroutine state

by Raymond Chen

From the article:

Last time, we hooked up the co_await of the simple_task and we had a brief glimpse into the the management of the reference count on the promise (and therefore also the coroutine state). Today we’ll fill in the rest of the story...

C++ coroutines: Awaiting the simple_task

by Raymond Chen

From the article:

Last time, we accepted the parameter passed to co_return and stored it into our promise. This time, we’ll deal with the consumption side and wait for the answer to appear...

Are you ready to modernize your C++ code using std::string_view?

Well, there might be some subtle bug hiding!

C++ coroutines: Accepting types via return_void and return_value

by Raymond Chen

From the article:

Last time, we built the result holder for our simple_task coroutine and showed how to move values into the holder and move them back out.

So now we’re actually going to move them in...
