| 2019-07-19 | fix shared array terminology. | Koichi Sasada | |
| Shared arrays created by Array#dup and so on points a shared_root object to manage lifetime of Array buffer. However, sometimes shared_root is called only shared so it is confusing. So I fixed these wording "shared" to "shared_root". * RArray::heap::aux::shared -> RArray::heap::aux::shared_root * ARY_SHARED() -> ARY_SHARED_ROOT() * ARY_SHARED_NUM() -> ARY_SHARED_ROOT_REFCNT() Also, add some debug_counters to count shared array objects. * ary_shared_create: shared ary by Array#dup and so on. * ary_shared: finished in shard. * ary_shared_root_occupied: shared_root but has only 1 refcnt. The number (ary_shared - ary_shared_root_occupied) is meaningful. | |||
| 2019-07-19 | In some situations, `vm_stack` can be NULL, but `cfp` is valid. | Samuel Williams | |
| 2019-07-19 | Add assertions to `coroutine_initialize_main`. | Samuel Williams | |
| 2019-07-19 | Split assertions to check which one fails. | Samuel Williams | |
| 2019-07-19 | Better usage of `rb_ec_clear_vm_stack` to maintain invariants. | Samuel Williams | |
| 2019-07-19 | Improve ec assertions. | Samuel Williams | |
| 2019-07-19 | respect NDEBUG. | Koichi Sasada | |
| ruby/ruby.h includes ruby/assert.h, and RUBY_NDEBUG is defined by checking NDEBUG. In other words, NDEBUG is only seen just after ruby/ruby.h. This patch also cheks NDEBUG just after including ruby_assert.h. Without this patch, assertions in array.c are always enabled. | |||

| [Feature #16003] [ruby-dev:50814] | |||
| 2019-07-19 | initialize only Fiber's cfp. | Koichi Sasada | |
| fiber->cont.saved_ec.cfp should be initialized by NULL because no vm_stack is allocated. However, cont_init() captures current Fiber's cfp for continuation, so it should only initialize fibers. | |||
| 2019-07-19 | Revert "Ensure cfp is initialized to NULL." | Samuel Williams | |
| This reverts commit d7fdf45a4ae1bcb6fac30a24b025d4f20149ba0a. | |||
| 2019-07-19 | Fix showing doc of "nil.to_s", nil doesn't have #name | aycabta | |
| 2019-07-19 | Ensure cfp is initialized to NULL. | Samuel Williams | |
| `cont_init` didn't initialize `cont->saved_ec.cfp`. Calling `cont_mark` would result in an invalid `cfp` in `rb_execution_context_mark`. Because fibers lazy-initialize the stack, fibers that are created but not resumed could cause this problem to occur. | |||
| 2019-07-19 | Remove `rb_vm_push_frame` as it is no longer used. | Samuel Williams | |

| 2019-07-18 | * remove trailing spaces. | git | |
| 2019-07-18 | Improve `fiber_pool_expand` allocation strategy. | Samuel Williams | |
| If `mmap` fails to allocate memory, try half the size, and so on. Limit FIBER_POOL_ALLOCATION_MAXIMUM_SIZE to 1024 stacks. In typical configurations this limits the memory mapped region to ~128MB per allocation. | |||
| 2019-07-18 | Add experimental `RUBY_SHARED_FIBER_POOL_FREE_STACKS` to control madvise. | Samuel Williams | |
| 2019-07-18 | Add note about setting `vm.max_map_count` for Linux. | Samuel Williams | |
| 2019-07-18 | Make fiber_pool more conservative on platforms with limited address space. | Samuel Williams | |
| We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address space is 32-bits or less. Fiber pool implementation enables more book keeping, and reduces upper limits, in order to minimise address space utilisation. | |||
| 2019-07-18 | Add `struct fiber_pool {int free_stacks;}` to control usage of madvise. | Samuel Williams | |
| `madvise(free)` and similar operations are good because they avoid swap usage by clearing the dirty bit on memory pages which are mapped but no longer needed. However, there is some performance penalty if there is no memory pressure. Therefore, we do it by default, but it can be avoided. | |||
| 2019-07-18 | Add FIBER_POOL_ALLOCATION_FREE to control allocation/free strategy. | Samuel Williams | |
| 2019-07-18 | Limit expansion of fiber pool on 32-bit platforms. | Samuel Williams | |
| On 32-bit platforms, expanding the fiber pool by a large amount may fail, even if a smaller amount may succeed. We limit the maximum size of a single allocation to maximise the number of fibers that can be allocated. Additionally, we implement the book-keeping required to free allocations when their usage falls to zero. | |||
| 2019-07-18 | Enable `madvise` to release stack space back to OS. | Samuel Williams | |
| 2019-07-18 | Add details of fiber pool and coroutine selection to NEWS. | Samuel Williams | |
| 2019-07-18 | Add `ucontext` and `copy` coroutine implementations to test matrix. | Samuel Williams | |
| 2019-07-18 | Improve build process and coroutine implementation selection. | Samuel Williams | |
| 2019-07-18 | Stack copying implementation of coroutines. | Samuel Williams | |
| 2019-07-18 | Remove unused vm_stack recycling. | Samuel Williams | |
| 2019-07-18 | Implement fiber pool for reduced fiber allocation overhead. | Samuel Williams | |
| Replace previous stack cache with fiber pool cache. The fiber pool allocates many stacks in a single memory region. Stack allocation becomes O(log N) and fiber creation is amortized O(1). Around 10x performance improvement was measured in micro-benchmarks. | |||

| Build dumped string from base packed data and extended year at once. Although currently ruby_marshal_write_long() never writes more than 5 bytes per its format specification, allocate `sizeof(long)+1` for the sanitation. | |||
