86a429aead WIP: generic variadic when_all() implementation. 2017-09-02 10:21:38 +09:30

d07d48eff0 Experimental implementation of generalised sync_wait(). 
Causes some test failures which I still need to look into.

de0b0f4395 Add #include <ostream> to shared_task_tests.cpp 
This fixes a missing-symbol linker error under Clang optimised
builds under Linux.

25a5207035 Put cancellation_token tests into a test suite. 2017-08-24 22:59:06 +09:30

62cff52fd1 Put local functions from tests into anonymous namespaces. 
This fixes some duplicate-symbol linker errors under Linux/Clang.
Both generator_test.cpp and recursive_generator_tests.cpp were
defining a 'range' function.

8a632c72a9 Don't link against 'c++abi' library under Linux/Clang. 
The README instructions say to use the libstdc++ ABI so we don't
need to use the libc++abi.

8e728932be Improvements to fmap() implementation 
- Added documentation to README
- Implemented fmap() for generator<T>, recursive_generator<T>,
  shared_task<T>.
- Centralised operator| overloads for fmap() in fmap.hpp.
- Now provide two-argument fmap() overloads as the type-specific
  implementations: fmap(func, value)
  This replaces the need for detail::apply_fmap() functions.

2160ab0208 Update reference to VS 2017.3 in docs now that it's released. 2017-08-17 22:24:30 +09:30
Lewis Baker
316ce6c7dd Modify task<T> to avoid potential for unbounded recursion. 
The await_suspend() method of operator co_await() now returns bool
instead of void, to allow it to resume execution without suspending
if the task completes synchronously. However, this unfortunately
requires use of std::atomic operations to decide a potential race
between the awaiter suspending and the coroutine running to
completion.

This avoids a stack-overflow error when a coroutine awaits a
long sequence of task<T> values that complete synchronously.
eg. in a loop.

bf9eb2c581 Rename lazy_task -> task, shared_lazy_task -> shared_task. 
No need to keep the 'lazy' term in the name to distinguish it
from eager tasks as all task are lazy now.

64b0a049f9 Remove eager task types task<T> and shared_task<T>. 
These types make it difficult to write exception-safe code
when compared with their lazy-task counterparts.

have an implementation of io_service for Linux.

421de76f18 Change when_all() tests to avoid use of task<T>. 
Use lazy_task, sync_wait and when_all instead.

b78bc3ed7b Update some tests to avoid using cppcoro::task<>. 
Use lazy_task<>, sync_wait() and when_all[_ready]() instead in
preparation for phasing out task<>.

4acf3d5a4e Only use /await:heapelide on x64 optimised. 
This flag is not supported for x86 targets yet.

d6f005342d Make lightweight_manual_reset_event methods noexcept. 
This is important to guarantee thread safety in some scenarios.

278c3181a6 Add detail::lightweight_manual_reset_event class. 
Uses futex() on Linux, WaitOnAddress() on Win8+ and falls back to
Win32 events on earlier versions of Windows.

abc4dd60e1 Compile with /nodefaultlib under MSVC so we're forced to list libs. 
This helps to ensure cake knows about those libraries which would
otherwise not be listed on the link line.

84fdbc7971 Add '-fuse-ld=lld` to link line to force use of LLD 
This avoids needing to setup the 'ld' symbolic link which points to 'lld'.

5f5bfa9649 Add 'value_type' typedefs to each of the task-types. 
This typedef just makes available the template parameter of the
task type. This can be useful when writing generic functions that
need to operate on any of the task-types.

c22bef61a9 Modify task classes to support storing callback and pointer. 
This allows registering continuations that are not coroutine
handles which can be useful for building some operators.
This comes at the expense of storage of an extra pointer per
coroutine and/or awaiter.

Adds the cppcoro::detail::resumer to wrap something that can
either be a callback + state or a coroutine_handle.
