These two function were almost identical, except in case of
T_STRING/T_FLOAT. Why not merge them into one, and let the difference be
handled in normal method calls (slowpath). This does not improve
runtime performance for me, but at least reduces for instance rb_eql_opt
from 653 bytes to 86 bytes on my machine, according to nm(1).
After sending SEGV signal, but no response. Try to add 2 more
seconds. If we can not have a detailed log, we need to use
gdb/lldb to show the backtrace.
This commit combines the sweep step with moving objects. With this
commit, we can do:
```ruby
GC.start(compact: true)
```
This code will do the following 3 steps:
1. Fully mark the heap
2. Sweep + Move objects
3. Update references
By default, this will compact in order that heap pages are allocated.
In other words, objects will be packed towards older heap pages (as
opposed to heap pages with more pinned objects like `GC.compact` does).
WSL 2 is officially released. It uses Linux kernel, so almost all specs
for Linux work on WSL, except one: gethostbyaddr. I guess network
resolution in WSL is based on Windows, so the behavior seems a bit
different from normal Linux.
This change adds `platform_is_not :wsl` guard, and guards out the test
in question.
getgrnam(3) says:
```
ERRORS
0 or ENOENT or ESRCH or EBADF or EPERM or ...
The given name or gid was not found.
```
Process::GID.from_name raises an ArgumentError for 0, but Errno::ESRCH
for ESRCH. Actually, WSL 2 raises Errno::ESRCH. This change accepts
all exceptions above.
If __builtin_assume() is enables and RUBY_DEBUG=0, RUBY_ASSERT(expr)
will be compiled to __builtin_assume(expr) and compiler can assume
expr is true and apply aggressive optimizations. However we observed
doubtful behavior because of compiler optimizations, we introduce
new macro RUBY_ASSERT_NOASSUME to disable __builtin_assume().
With this macro, we can try without __builtin_assume().
BASERUBY needs to be at least Ruby 2.2 since
46acd0075d.
I think it's better to explicitly fail early as soon as BASERUBY
is used in this case, versus trying to debug later failures.
This modifies things to check both implicitly use of ruby in the
PATH as BASERUBY, and explicitly specified older versions of ruby
when using --with-baseruby.
Fixes [Bug #16668]
