[Bug #19289] Retain `ruby_abi_version` function A few extension libraries, to hide all symbols except for necessary to load, hardcode the symbols to be exported in symbol list files for linker without even checking by `have_func`. As a workaround for such libraries, retain `ruby_abi_version` symbol always even in released versions for now. --- include/ruby/internal/abi.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
* See https://bugs.ruby-lang.org/issues/19078#note-30
The documentation says that the `end` pointer will be marked but looking at the source, that is not the case.
Although the storage of the opaque Ruby object is an array of VALUEs, the intention of RB_ALLOCV is to allocate bytes of memory.
* Slightly more consistent indentation with other parts of the document.
The following new debug context APIs are for implementing debugger's `next` (step over) and similar functionality. * `rb_debug_inspector_frame_depth(dc, index)` returns `index`-th frame's depth. * `rb_debug_inspector_current_depth()` returns current frame depth. The frame depth is not related to the frame index because debug context API skips some special frames but proposed `_depth()` APIs returns the count of all frames (raw depth).
