Ruby master - Feature #17472 (Rejected): HashWithIndifferentAccess like Hash extension
https://redmine.ruby-lang.org/issues/17472
2020-12-26T11:04:18Z

<p>Rails has <a href="https://api.rubyonrails.org/classes/ActiveSupport/HashWithIndifferentAccess.html" class="external">ActiveSupport::HashWithIndifferentAccess</a>, which is widely used in Rails to handle Request, Session, ActionView's form construction, ActiveRecord's DB communication, and so on. It receives String or Symbol and normalize them to fetch the value. But it is implemented with Ruby. If we provide C implementation of that, Rails will gain the performance improvement.</p>

Ruby master - Feature #17468 (Closed): Deprecate RUBY_DEVEL

<p>Some configuration of Ruby use RUBY_DEVEL, which depends PATCH_LEVEL.<br>
But depending PATCH_LEVEL causes issues which will become revealed on the final release.<br>
Though we release some previews and RCs, they don't contributes the quality around RUBY_DEVEL.</p>
<p>Therefore to ensure CI tests the quality of the final release, we need to deprecate RUBY_DEVEL.</p>
Ruby master - Feature #16275 (Closed): Revert `.:` syntax
https://redmine.ruby-lang.org/issues/16275
2019-10-23T15:26:13Z

<p><code>obj.:method</code> is introduced at r66667 by <a class="issue tracker-2 status-1 priority-4 priority-default" title="Feature: Proposal: Shorthand operator for Object#method (Open)" href="https://redmine.ruby-lang.org/issues/12125">#12125</a> and <a class="issue tracker-2 status-5 priority-4 priority-default closed" title="Feature: Syntax sugar for method reference (Closed)" href="https://redmine.ruby-lang.org/issues/13581">#13581</a>.<br>
It encourages the functional programming style in Ruby.</p>
<p>But this shorthand syntax is just for methods of <code>self</code> without arguments.<br>
It causes another feature requests like <a class="issue tracker-2 status-1 priority-4 priority-default" title="Feature: Proposal: Shorthand operator for "#instance_method" (Open)" href="https://redmine.ruby-lang.org/issues/16273">#16273</a> (and lambda compositions like <a class="issue tracker-1 status-7 priority-4 priority-default closed" title="Bug: Refactor Proc#>> and #<< (Feedback)" href="https://redmine.ruby-lang.org/issues/15428">#15428</a>).</p>
<p>Such features will introduce a new view of Ruby but no one illustrates the whole picture yet.<br>
I worried about such patch work may cause a conflict with future expansion of functional programing style or a just a garbage feature.</p>
<p><code>.:</code> syntax is introduced in 2.7.0 preview1, not released in production yet.<br>
How about reverting at this time and re-introduce with a big picture.</p>
Ruby master - Feature #16131 (Closed): Remove $SAFE, taint and trust
https://redmine.ruby-lang.org/issues/16131
2019-08-29T07:14:34Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>Ruby had Taint checking which is originally introduced in Perl.<br>
<a href="https://en.wikipedia.org/wiki/Taint_checking" class="external">https://en.wikipedia.org/wiki/Taint_checking</a></p>
<p>It was intended to provide a useful tool for handle objects which are come from outside.<br>
Input data is set as tainted by default and call untaint if you checked or filtered the value.<br>
Some people used this feature in the age of CGI.</p>
<p>But these days, no one use the mechanism and input libraries usually doesn't support it.<br>
For example rack, as following shows its input is not tainted and the mechanism is unusable.</p>
<pre><code>% cat foo.ru
run ->(env) do
['200', {'Content-Type' => 'text/plain'}, ["Is QUERY_STRING tainted?: #{env["QUERY_STRING"].tainted?}"]]
end
% rackup foo.ru
[51724] Puma starting in cluster mode...
[51724] * Version 3.12.1 (ruby 2.6.3-p62), codename: Llamas in Pajamas
[51724] * Min threads: 3, max threads: 3
[51724] * Environment: development
[51724] * Process workers: 1
[51724] * Preloading application
[51724] * Listening on tcp://localhost:9292
[51724] Use Ctrl-C to stop
[51737] + Gemfile in context: /Users/naruse/work/td-cdp-api/Gemfile
[51724] - Worker 0 (pid: 51737) booted, phase: 0
</code></pre>
<pre><code>% curl http://localhost:9292/\?foo=1
Is QUERY_STRING tainted?: false
</code></pre>
<p>Therefore I think Taint checking mechanism is unusable on the current Ruby ecosystem.</p>
<p>On the other hand we experienced multiple vulnerability around $SAFE and taint mechanism.<br>
<a href="https://cse.google.com/cse?q=taint&cx=008288045305770251182%3Afvruzsaknew&ie=UTF-8" class="external">https://cse.google.com/cse?q=taint&cx=008288045305770251182%3Afvruzsaknew&ie=UTF-8</a><br>
The cost of maintaining it is expensive.</p>
<p>In conclusion, I think the taint mechanism is too expensive to maintain for the merit of it.<br>
I suggest to remove it.</p>
Ruby master - Bug #15992 (Closed): An exception breaks monitor state and cause deadlock
https://redmine.ruby-lang.org/issues/15992
2019-07-10T06:55:40Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>lib/monitor.rb provides Monitor.<br>
But its state handling is weak for interrupts caused by Thread.kill for example timeout libraries.</p>
<p>Timeout exception may happen everywhere. If it raised when the thread is executing</p>
<pre><code class="ruby syntaxhl" data-language="ruby"> <span class="k">def</span> <span class="nf">mon_exit</span>
<span class="n">mon_check_owner</span>
<span class="vi">@mon_count</span> <span class="o">-=</span><span class="mi">1</span>

<p>It breaks the state of the monitor and it causes deadlock.</p>
Ruby master - Feature #15958 (Closed): Time#inspect with frac
https://redmine.ruby-lang.org/issues/15958
2019-06-25T13:12:18Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>When Matz changed Time#to_s format in 2006, frac part of Time string is dropped because it is considered not useful.<br>
<a href="https://blade.ruby-lang.org/ruby-dev/29440">[ruby-dev:29440]</a></p>
<p>But recently we encounters some troubles the comparison of Time objects whose frac parts are different.<br>
<a href="https://twitter.com/__gfx__/status/1143056072422219776" class="external">https://twitter.com/__gfx__/status/1143056072422219776</a></p>
<p>For example a is original object and b is once stored in RDB (and dropped the frac part).<br>
Or there're multiple time objects which are generated in a single HTTP request.<br>
Of course they are different and assert_equal will be failed but inspect doesn't show the frac part.</p>

<p>After r59449 <code>nmake</code> failes to run when making ripper and so on.<br>
It because miniruby sets UTF-8 encoding even though the content is CP932 (on Japanese Windows).<br>
It should set ASCII-8BIT and handle as it is.</p>
<pre><code>ripper:
" Could not be configured. It will not be installed."
" C:/ruby-trunk/lib/mkmf.rb:1560: invalid byte sequence in UTF-8"
" Check ext/ripper/mkmf.log for more details."
*** Fix the problems, then remove these directories and try again if you want.

<p>I sometimes write following code.</p>
<pre><code class="ruby syntaxhl" data-language="ruby"><span class="n">ary</span> <span class="o">=</span> <span class="n">some_metho_returns_nil_or_empty_container</span><span class="p">()</span> <span class="c1"># nil or "" or [] or {}</span>

<span class="c1"># some code</span>
<span class="k">end</span>
</code></pre>
<p>But the condition <code>ary && !ary.empty?</code> is too long and complex.<br>
Though Ruby 2.3 introduces <code>&.</code>, but this can’t be written as <code>ary&.empty?</code>.</p>
<p>One idea is add <code>nonempty?</code> write as <code>ary&.nonempty?</code>.</p>
<p>akr: <code>nonempty?</code> is not good name because human is not good at handling</p>
<p>This discussion matches following core classes:</p>
<ul>
<li>String</li>
<li>Array</li>
<li>Hash</li>

<p>r41041 で、ブロック呼び出し前の VM 内の処理中に Ruby のメソッドが何らかの理由で呼ばれると argv が壊れるという問題を直しました。<br>
具体的には、</p>
<pre><code class="ruby syntaxhl" data-language="ruby"><span class="n">y</span> <span class="o">=</span> <span class="no">Object</span><span class="p">.</span><span class="nf">new</span>
<span class="k">def</span> <span class="nc">y</span><span class="o">.</span><span class="nf">s</span><span class="p">(</span><span class="n">a</span><span class="p">)</span>
<span class="k">yield</span><span class="p">(</span><span class="n">a</span><span class="p">)</span>
<span class="k">end</span>
<span class="n">m</span> <span class="o">=</span> <span class="no">Object</span><span class="p">.</span><span class="nf">new</span>
<span class="k">def</span> <span class="nc">m</span><span class="o">.</span><span class="nf">method_missing</span><span class="p">(</span><span class="o">*</span><span class="n">a</span><span class="p">)</span>
<span class="k">super</span>
<span class="k">end</span>
<span class="n">assert_equal</span> <span class="p">[</span><span class="n">m</span><span class="p">,</span> <span class="kp">nil</span><span class="p">],</span> <span class="n">y</span><span class="p">.</span><span class="nf">s</span><span class="p">(</span><span class="n">m</span><span class="p">){</span><span class="o">|</span><span class="n">a</span><span class="p">,</span><span class="n">b</span><span class="o">|</span><span class="p">[</span><span class="n">a</span><span class="p">,</span><span class="n">b</span><span class="p">]}</span>
</code></pre>
<p>のようなコードの場合、</p>
<ul>
<li>
<code>y.s</code> に <code>m</code> と <code>block</code> が渡される</li>
<li>
<code>y.s</code> で <code>yield(a)</code> が呼ばれる</li>
<li>
<code>argv</code>が設定される</li>
<li>
<code>vm_invoke_block</code> 内の <code>VALUE * const rsp = GET_SP() - ci->argc; SET_SP(rsp);</code> で <code>argv</code> の先頭に <code>sp</code> が設定される</li>
<li><code>vm_yield_setup_args</code></li>
<li><code>vm_yield_setup_block_args</code></li>
<li>
<code>y.s</code> のブロックパラメータは2つなのに、引数は一つなので、<code>a.to_ary</code> が呼ばれる (<code>rb_check_array_type(arg0)</code>)</li>
<li>
<code>method_missing</code> が呼ばれる</li>
<li>
<code>super</code> が呼ばれる (このへんで <code>vm _push_frame</code> が呼ばれる)</li>
<li>
<code>vm_push_frame</code>のinitialize local variablesのところで<code>argv</code>に<code>nil</code>が代入されて破壊される</li>
</ul>
<p>で、これ自体は <code>argv</code> を対比しておいて戻せばよいです。<br>
また、<code>SET_SP(rsp)</code>のあたりは、ささださん曰く「 <code>argv</code> に書き込みがない、という前提でそこは作ってるんだよね」だそうな。<br>
しかし、「そんな前提わかるかっ」ですし、<br>
methodの方は <code>SAVE_RESTORE_CI(tmp = rb_check_convert_type(ary, T_ARRAY, "Array", "to_a"), ci);</code> ともうちょっとわかりやすく書いてあるので、<br>
「頂いた問題点を元に、一度全部総点検が必要そうです」とのことですので、お願いします。</p>

<p>GC中にstack overflowが発生すると、例外作成時にrb_new_objするので[BUG]ります。</p>
<p>原因<br>
(1) caller のテストで Fiber を利用するようにした<br>
(2) caller 実行中に GC が発生<br>
(3) GC 中にマシンスタックオーバーフロー(SEGV)が発生<br>
(4) スタックオーバーフローエラーを作成<br>
(5) スタックオーバーフローエラーを作るときに object allocation している<br>
(6) -> [BUG]</p>
<p>対処法:<br>
スタックオーバーフローエラーを投げるときはオブジェクト作らないようにする<br>
対症療法:<br>
caller のテストで Fiber を使わないようにする<br>
対症療法その2:<br>
callerのテストで GC.disable</p>
<p>nariさんがGC で再帰しないようにするなんて構想も先日語っておられましたが。</p>

Ruby master - Bug #6441 (Rejected): IO.pipe on ENFILE
https://redmine.ruby-lang.org/issues/6441

<p>今の Ruby は open(2) などで、errno=ENFILE が発生した場合、<br>
すなわち fd を使いきっている場合には、rb_gc() を呼び、IO オブジェクトを GC して、<br>
fd が解放されないか試み、それでもダメだったら諦めるとしています。</p>
<p>しかし、IO.pipe の場合はこれに失敗することがあります。<br>
これは、lazy sweep が上記の目的のため T_FILE の場合は直ちに sweep することにしている所、<br>
pipe の場合はその例外にあたらないからです。</p>

Ruby master - Bug #6272 (Closed): Rinda sticks on some tests

<p>Rindaが例えば以下のようにすると刺さります。</p>
<p>while [ yes ];do;make test-all TESTS='-v -n test_ruby_talk_264062 rinda/test_rinda.rb' RUBYOPT=-w;done</p>
<p>しばらく追ってみたところ、Rinda は Monitor#synchronize をすることで同期を守っているのですが、<br>
そのテストでは時刻を Rinda::MockClock で扱い、その中で Rinda::MockClock::MyTS を用いて時刻を配信しているのですが、<br>
この TupleSpace は複数のスレッドから触られるため、同一のスレッドからなら何度入ってもロックしない<br>
Monitor#synchronize でも、デッドロックしてしまうからっぽい気がします。</p>

Ruby master - Bug #5813 (Closed): net/http's EOFError and Keep-Alive
https://redmine.ruby-lang.org/issues/5813

naruse (Yui NARUSE)
naruse@airemix.jp
<p><a href="https://blade.ruby-lang.org/ruby-dev/39421">[ruby-dev:39421]</a> describes exceptions thrown by open-uri, and raise a question why net/http raises EOFError.</p>
<p>net/http sometimes raises EOFError.<br>
I recently find it is because of Keep-Alive.<br>
On HTTP/1.1, connections are Keep-Alive and a Keep-Alive connection has a timeout.<br>
If a client of such connection doesn't send anything after some communication,<br>
server closes the connection because of Keep-Alive timeout,<br>
and the client's connection shall raise EOFError (sometimes it may be ECONNRESET).</p>
<p>HTTP/1.1 says a client should retry a request if the request is idempotent.<br>
<a href="http://tools.ietf.org/html/rfc2616#section-8.1.4" class="external">http://tools.ietf.org/html/rfc2616#section-8.1.4</a><br>
<a href="http://tools.ietf.org/html/draft-ietf-httpbis-p1-messaging-17#section-6.1.5" class="external">http://tools.ietf.org/html/draft-ietf-httpbis-p1-messaging-17#section-6.1.5</a><br>
<a href="http://www.studyinghttp.net/connections" class="external">http://www.studyinghttp.net/connections</a><br>
So I attached a patch to such retry to net/http.</p>
<p>FYI, this timeout of Keep-Alive, KeepAliveTimeout, is:<br>
Apache in FreeBSD ports or pkgsrc is 5 seconds,<br>
the on in Debian Packages or RPM is 15 seconds.</p>

Ruby master - Bug #5790 (Closed): net/http の EOFError と Keep-Alive
https://redmine.ruby-lang.org/issues/5790

naruse (Yui NARUSE)
naruse@airemix.jp
<p><a href="https://blade.ruby-lang.org/ruby-dev/39421">[ruby-dev:39421]</a> がずっと心に残っていたので、思い立って調べてみたので、<br>
(正確には自分が高頻度で踏むようになったので調べてみた)<br>
その調査結果と対策案を提案します。</p>
<p>まず、投げられる原因ですが、根本的な原因は Keep-Alive のタイムアウトです。<br>
HTTP/1.1 ではデフォルトで持続的接続を行うので、複数回のリクエストに渡って<br>
一つの socket が使い回されます。</p>
<p>しかし、リクエスト同士で時間が開いていると、サーバー側でタイムアウトする<br>
可能性があります。この時にクライアント側の read(2) が 0 を返す、<br>
つまり EOFError となることがあります。</p>
<p>HTTP/1.1 は、冪等なメソッドの場合には確認なしにリトライすべきと言っているので、<br>
そのようにするパッチを添付します。<br>
冪等でないメソッドの場合にどうするべきかは悩ましいところです。<br>

<a href="http://www.studyinghttp.net/connections" class="external">http://www.studyinghttp.net/connections</a></p>
<p>なお、この Keep-Alive における Timeout は、<br>
Apache の場合、FreeBSD ports や pkgsrc では 5 秒、<br>
Debian Packages や RPM では 15 秒でした。</p>

<p>OpenSSL::Engine.load() loads engines and register them, and it may change the behavior of some existing methods.</p>
<p>For example on NetBSD 6 with cryptodev, it effects DH as folloing:<br>
./ruby -ropenssl -e'p OpenSSL::PKey::DH.new(256).public_key.private?;p OpenSSL::Engine.load;p OpenSSL::PKey::DH.new(256).public_key.private?'<br>
false<br>
true<br>
true</p>
<p>After loads cryptodev and register it (yes, it needs register. current ext/openssl can't register a engine),<br>
OpenSSL::PKey::DH#private?'s behavior seems to be changed.</p>
<p>Whether it is a bug or not, test/openssl/test_engine.rb should be fixed.</p>

Ruby master - Feature #5180 (Closed): net/http の接続時に用いる IP アドレスの指定

naruse (Yui NARUSE)
naruse@airemix.jp
<p>通常 net/http を使う時は、Net::HTTP.start("ruby-lang.org") などとホスト名を使います。<br>
で、Socket がホスト名から IP アドレスを引いて、コネクションが張られます。<br>
普通の人はこれで足りるわけですが、ふつうな人はしばしば DNS で引けない IP アドレスに接続したくなります。<br>
例えば、ホスト名は "ruby-lang.org" としたいが、IP アドレスは 127.0.0.1 とか。</p>
<p>以下のパッチをあてると、<br>
Net::HTTP.start("ruby-lang.org", ipaddr: '127.0.0.1')<br>
などとできるようになります。</p>

naruse (Yui NARUSE)
naruse@airemix.jp
<p>はい、リリース前恒例! サポートプラットフォーム決めのお時間がやって参りました。</p>
<p>前回は 1.9.1 リリース時だったわけですが、あれからずいぶんと経ったので、<br>
改めてサポートするプラットフォームを決めましょう。</p>
<p>== これまでのあらすじ</p>
<p><a href="http://redmine.ruby-lang.org/projects/ruby-19/wiki/SupportedPlatformsJa" class="external">http://redmine.ruby-lang.org/projects/ruby-19/wiki/SupportedPlatformsJa</a></p>
<p>== 決め方</p>
<p>サポートしたいプラットフォームがある方は宣言してください。<br>
ただし、当該プラットフォーム固有っぽいバグがあった場合、そのチケットをアサインする事があるので、<br>
覚悟を決めてから宣言してください。</p>
<p>いつでも「サポート終了!」は宣言できるので [要出典] お気軽にご応募くださいませ。</p>
<p>なお、1.9.3 のリリースのちょっと前あたりで一度締めとする予定です。</p>
<p>== 成瀬の提案</p>
<p>さて、前回のサポートプラットフォーム決めでいくつか反省があるので、ここに一つ提案を行います。</p>
<blockquote>
<p>なお、「メンテナがいる」とは明確なプラットフォームメンテナがいるもの(mswin32など)のほかに、「日々その環境でRubyを開発しているコミッタがいるもの」を含む。</p>
</blockquote>
<p>この後半を削ることを提案します。<br>
例として、Debian はいまだに lenny 32bit が対象になってしまっています。<br>
ようするに切るタイミングが決まらなかったという話で、<br>
こういうのはえいやで決める人がいるべきだろうと思うわけです。</p>
<p>== 現在のメンテナ</p>
<p>ちなみに現在のメンテナは以下の通りです。</p>
<p>mswin32, mswin64 (Microsoft Windows):<br>
NAKAMURA Usaku (usa)<br>
mingw32 (Minimalist GNU for Windows):<br>
Nobuyoshi Nakada (nobu)<br>
IA-64 (Debian GNU/Linux):<br>
TAKANO Mitsuhiro (takano32)<br>
Symbian OS:<br>
Alexander Zavorine (azov)<br>
AIX:<br>
Yutaka Kanemoto (kanemoto)<br>
FreeBSD:<br>
Akinori MUSHA (knu)<br>
Solaris:<br>
Naohisa Goto</p>
<p>逆にメンテナがいない主なプラットフォーム(と備考)は以下の通りです。</p>
<ul>
<li>Debian</li>
<li>Ubuntu</li>
<li>CentOS</li>
<li>Mac OS X (LLVM絡みが微妙)</li>
<li>cygwin (動かない)</li>
<li>NetBSD (動く)</li>
<li>OpenBSD (動かない気がする)</li>
<li>DragonFlyBSD (動かない)</li>

<p>最近の Date の変更で、以下のように RubySpec が失敗しています。<br>
RubySpec 側を直した方がいい物もあるような気がしますが、Date 側の問題もあるようなので確認頂けますか。<br>
spec 側を直すべきものについてはあるべき挙動を教えて頂ければそう直します。</p>
<p>なお、RubySpec は <a href="http://rubyspec.org/" class="external">http://rubyspec.org/</a> です。<br>
RubySpec を実行するには、git をインストールした上で、<br>
make update-rubyspec<br>
すると、spec/rubyspec 下に rubyspec のコードが持ってこられるので、<br>
make test-rubyspec MSPECOPT='-V -j -f s /library/date/civil_spec.rb'<br>
などとすれば該当のテストだけを走らせることができます。</p>

<p>NetBSD 5.0.[01] において、main thread 以外の pthread から fork すると、<br>
pthread とカーネルスレッド (lwp) との関連が壊れるという現象が確認されています。</p>
<p>後述のパッチがあまりにアレなのでこの問題は Third Party's Issue とし、<br>
Ruby 側では修正を入れない事としますが、情報の共有と記録のために<br>
ここにチケットを切っておきます。</p>
<p>なお、この workaround の作成には @_enamiさんの助けがありました。</p>
<p>追記:<br>
NetBSD 側では kern/42772 として報告、修正されています。<br>

atanh(1) は NaN となります。</p>
<p>RETURN VALUES<br>
If |x|>=1, atanh(x) and atanhf(x) return +inf, -inf or NaN, and sets the<br>
global variable errno to EDOM.</p>
<p>しかし、FreeBSD7 では以下のようになっており、atanh(1) は infinity を返します。</p>
<p>RETURN VALUES<br>
The atanh() and the atanhf() functions return the inverse hyperbolic tan-<br>
gent of x if successful. If the argument has absolute value 1, a divide-<br>
by-zero exception is raised and an infinity is returned. If |x| > 1, an<br>
invalid exception is raised and an NaN is returned.</p>
