For the remote object `ro`, method chain like `ro.foo.bar` the
result of `ro.foo` is stored in `@result`, but cleared just
before `setup_message` and it seems GCed on specific machine.

To prevent collecting, clear `@result` just after `setup_message`
and `setup_message` can get the last result object.
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.
My previous fix in d0ed935d5b was
not correct, as pointed out by cremno on GitHub.
This simplifies things by just using Kernel#to_s. Also switch to
bind_call(obj) instead of bind(obj).call for better performance.
This rescues some exceptions that could happen with a closed or
shutdown DRb socket. This can prevent the server from
exiting if an client socket is closed directly after it is
accepted.
Fixes [Bug #8039]
This makes it so that client instances that call a method on a
server-side object that raise a subclass of Exception are handled
similarly to those that raise a subclass of StandardError.
Only reraise exceptions that we are fairly sure we don't want to
rescue.
Fixes [Bug #5618]
* Handle BasicObject in drb
Also fix a bug in rescue clause of any_to_s because sprintf
does not handle the %l modifier.
Fixes [Bug #7833]
* Do not send a reply to the client if there is a connection error
This allows for normal TCP shutdown (fin-ack-fin-ack instead of
fin-ack-push-rst).
Patch from pierre@mouraf.org (Pierre-Alexandre Meyer).
Fixes [Bug #2339]
* Detect fork and do not reuse forked connections in drb
This associates each DRbConn with a pid, and if the pid changes,
it closes any DRbConns in the pool with a pid that no longer
matches. This fixes DRb servers from sending messages intended
for one client to another client after forking.

Closing a listen socket while entering select(2) may
trigger IOError or even deadlock because another thread
may give the file descriptor to another file description;
meaning the kernel can wait on the wrong description.

IO#close is idempotent, so we don't need to waste bytecode
to check or nil it at shutdown time.

* vm_core.h (rb_vm_t): move `rb_execution_context_t::safe_level` to
`rb_vm_t::safe_level_` because `$SAFE` is a process (VM) global state.
* vm_core.h (rb_proc_t): remove `rb_proc_t::safe_level` because `Proc`
objects don't need to keep `$SAFE` at the creation.
Also make `is_from_method` and `is_lambda` as 1 bit fields.
* cont.c (cont_restore_thread): no need to keep `$SAFE` for Continuation.
* eval.c (ruby_cleanup): use `rb_set_safe_level_force()` instead of access
`vm->safe_level_` directly.
* eval_jump.c: End procs `END{}` doesn't keep `$SAFE`.
* proc.c (proc_dup): removed and introduce `rb_proc_dup` in vm.c.
* safe.c (rb_set_safe_level): don't check `$SAFE` 1 -> 0 changes.
* safe.c (safe_setter): use `rb_set_safe_level()`.
* thread.c (rb_thread_safe_level): `Thread#safe_level` returns `$SAFE`.
It should be obsolete.
* transcode.c (load_transcoder_entry): `rb_safe_level()` only returns
0 or 1 so that this check is not needed.
* vm.c (vm_proc_create_from_captured): don't need to keep `$SAFE` for Proc.
* vm.c (rb_proc_create): renamed to `proc_create`.
* vm.c (rb_proc_dup): moved from proc.c.
* vm.c (vm_invoke_proc): do not need to set and restore `$SAFE`
for `Proc#call`.
* vm_eval.c (rb_eval_cmd): rename a local variable to represent clearer
meaning.
* lib/drb/drb.rb: restore `$SAFE`.
* lib/erb.rb: restore `$SAFE`, too.
* test/lib/leakchecker.rb: check `$SAFE == 0` at the end of tests.
* test/rubygems/test_gem.rb: do not set `$SAFE = 1`.

* lib/drb/drb.rb: avoid creating a Thread and call the shutdown logic
directly. Do not try to kill or join the current Thread.
Thread.new { stop_service } caused "can't alloc thread (ThreadError)",
which is shown with Thread.report_on_exception = true.

Sockets are close-on-exec by default since Ruby 2.0, so it
is redundant to set it again.

In case a process encounters high-numbered FDs, this allows
consistent performance on systems with ppoll support.
[ruby-core:35572]
