As @jeremyevans pointed out for commit eb2d8b1:
> Each Tempfile instance has a separate File instance and file descriptor:

> t = Tempfile.new
> t.to_i # => 6
> t.dup.to_i => 7
FinalizerManager will keep track of the open File objects for the
particular file and will only unlink the file when all of the File objects
have been closed.
https://github.com/ruby/tempfile/commit/753ab16642
The Closer and Remover finalizers are defined on different objects in
Tempfile. The Closer is defined on the Tempfile object while the Remover
is defined on the finalizer_obj. This means that there is no guarantee
of the finalizer order.
On Windows, we must close the file before removing it because we cannot
remove an open file. But since the order is not guaranteed, the GC may
run the Remover finalizer first, which will fail with an Errno::EACCES
(Permission denied @ apply2files).
This commit changes it so that both the Closer and Remover finalizers
are defined on the finalizer_obj, which guarantees the order that it is
ran.

The keyword argument `anonymous` is implemented for `Tempfile.create`
The default is `anonymous: false`.
The behavior is not changed as before.
The created temporary file is immediately removed if `anonymous: true` is specified.
So applications don't need to remove the file.
The actual storage of the file is reclaimed by the OS when the file is closed.
It uses `O_TMPFILE` for Linux 3.11 or later.
It creates an anonymous file from the beginning.
It uses FILE_SHARE_DELETE for Windows.
It makes it possible to remove the opened file.
[Feature #20497]
Instead of storing the delegate in @tmpfile, use __getobj__, since
delegate library already handles dup/clone for that. Copy the
unlinked, mode, and opts instance variables to the returned object
when using dup/clone.
Split the close/unlink finalizer into two finalizers. The close
finalizer always closes when any Tempfile instance is GCed, since
each Tempfile instance uses a separate file descriptor. The unlink
finalizer unlinks only when the original and all duped/cloned
Tempfiles are GCed, since all share the same path.
For Tempfile#open, undefine the close finalizer after closing the
current file, the redefine the close finalizer with the new file.
Fixes [Bug #19441]
https://github.com/ruby/tempfile/commit/dafabf9c7b
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.
Cfuncs that use rb_scan_args with the : entry suffer similar keyword
argument separation issues that Ruby methods suffer if the cfuncs
accept optional or variable arguments.
This makes the following changes to : handling.
* Treats as **kw, prompting keyword argument separation warnings
if called with a positional hash.
* Do not look for an option hash if empty keywords are provided.
For backwards compatibility, treat an empty keyword splat as a empty
mandatory positional hash argument, but emit a a warning, as this
behavior will be removed in Ruby 3. The argument number check
needs to be moved lower so it can correctly handle an empty
positional argument being added.
* If the last argument is nil and it is necessary to treat it as an option
hash in order to make sure all arguments are processed, continue to
treat the last argument as the option hash. Emit a warning in this case,
as this behavior will be removed in Ruby 3.
* If splitting the keyword hash into two hashes, issue a warning, as we
will not be splitting hashes in Ruby 3.
* If the keyword argument is required to fill a mandatory positional
argument, continue to do so, but emit a warning as this behavior will
be going away in Ruby 3.
* If keyword arguments are provided and the last argument is not a hash,
that indicates something wrong. This can happen if a cfunc is calling
rb_scan_args multiple times, and providing arguments that were not
passed to it from Ruby. Callers need to switch to the new
rb_scan_args_kw function, which allows passing of whether keywords
were provided.
This commit fixes all warnings caused by the changes above.
It switches some function calls to *_kw versions with appropriate
kw_splat flags. If delegating arguments, RB_PASS_CALLED_KEYWORDS
is used. If creating new arguments, RB_PASS_KEYWORDS is used if
the last argument is a hash to be treated as keywords.
In open_key_args in io.c, use rb_scan_args_kw.
In this case, the arguments provided come from another C
function, not Ruby. The last argument may or may not be a hash,
so we can't set keyword argument mode. However, if it is a
hash, we don't want to warn when treating it as keywords.
In Ruby files, make sure to appropriately use keyword splats
or literal keywords when calling Cfuncs that now issue keyword
argument separation warnings through rb_scan_args. Also, make
sure not to pass nil in place of an option hash.
Work around Kernel#warn warnings due to problems in the Rubygems
override of the method. There is an open pull request to fix
these issues in Rubygems, but part of the Rubygems tests for
their override fail on ruby-head due to rb_scan_args not
recognizing empty keyword splats, which this commit fixes.
Implementation wise, adding rb_scan_args_kw is kind of a pain,
because rb_scan_args takes a variable number of arguments.
In order to not duplicate all the code, the function internals need
to be split into two functions taking a va_list, and to avoid passing
in a ton of arguments, a single struct argument is used to handle
the variables previously local to the function.
If uplevel keyword is given, the warning message is prepended
with caller file and line information and the string "warning: ".
The use of the uplevel keyword makes Kernel#warn format output
similar to how rb_warn formats output.
This patch modifies net/ftp and net/imap to use Kernel#warn
instead of $stderr.puts or $stderr.printf, since they are used
for printing warnings.
This makes lib/cgi/core and tempfile use $stderr.puts instead of
warn for debug logging, since they are used for debug printing
and not for warning.
This does not modify bundler, rubygems, or rdoc, as those are
maintained outside of ruby and probably wish to remain backwards
compatible with older ruby versions.
rb_warn_m code is originally from nobu, but I've changed it
so that it only includes the path and lineno from uplevel
(not the method), and also prepends the string "warning: ",
to make it more similar to rb_warn.

RDoc doesn't understand an asterisk inside the plus markers. Moving them
out of the markers looks better.
