Header file include/ruby/internal/abi.h contains RUBY_ABI_VERSION which
is the ABI version. This value should be bumped whenever an ABI
incompatible change is introduced.
When loading dynamic libraries, Ruby will compare its own
`ruby_abi_version` and the `ruby_abi_version` of the loaded library. If
these two values don't match it will raise a `LoadError`. This feature
can also be turned off by setting the environment variable
`RUBY_RUBY_ABI_CHECK=0`.
This feature will prevent cases where previously installed native gems
fail in unexpected ways due to incompatibility of changes in header
files. This will force the developer to recompile their gems to use the
same header files as the built Ruby.
In Ruby, the ABI version is exposed through
`RbConfig::CONFIG["ruby_abi_version"]`.
The existing implementation, given the below .inputrc, erroneously
creates a "C-v" key binding:
set keymap emacs-ctlx
"\C-v": "[C-x C-v was pressed]"
This fixes it to instead create a "C-x C-v" keybinding.

Also, the default error printer and Exception#full_message use the
method instead of `Exception#message` to get the message string.
`Exception#detailed_message` calls `Exception#message`, decorates and
returns the result. It adds some escape sequences to highlight, and the
class name of the exception to the end of the first line of the message.
[Feature #18370]
This is the beginning of an extended explication of Ruby encoding.
One of its more important jobs is to provide link targets for encoding documentation in other classes (String, File, IO, etc.). In particular, they can link to the "Encoding Options" section.
I'll have much to add to this document going forward, along with suitable adjustments in the class documentation.
the original rb_wasm_setjmp implementation always unwinds to the root
call frame to have setjmp compatible interface, and simulate sjlj's
undefined behavior. Therefore, every vm_exec call unwinds to main, and
a deep call stack makes setjmp call very expensive. The following
snippet from optcarrot takes 5s even though it takes less than 0.3s on
native.
```
[0x0, 0x4, 0x8, 0xc].map do |attr|
(0..7).map do |j|
(0...0x10000).map do |i|
clr = i[15 - j] * 2 + i[7 - j]
clr != 0 ? attr | clr : 0
end
end
end
```
This patch adds a WASI specialized vm_exec which uses lightweight
try-catch API without unwinding to the root frame. After this patch, the
above snippet takes only 0.5s.
This method takes a block and yields Thread::Backtrace::Location
objects to the block. It does not take arguments, and always
starts at the default frame that caller_locations would start at.
Implements [Feature #16663]
The `CC` found by `AC_CHECK_TOOL` is prefixed by the host triplet
when cross compiling. To search for commands with `AC_CHECK_TOOL`
based on that `CC` means to search also doubly prefixed names.
