Ruby master - Feature #17468 (Closed): Deprecate RUBY_DEVEL
https://redmine.ruby-lang.org/issues/17468
2020-12-25T09:32:50Z
naruse (Yui NARUSE)
naruse@airemix.jp
<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 - Misc #17376 (Assigned): Reduce number of GitHub Actions

<p>At this time we have 127 checks for GitHub commits, but unfortunately GitHub UI only shows 100 checks.<br>
It sometimes makes we don't see a failed check.<br>
Could you reduce number of GitHub actions at least less than 100?</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

<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>
<span class="k">if</span> <span class="vi">@mon_count</span> <span class="o">==</span> <span class="mi">0</span>
<span class="vi">@mon_owner</span> <span class="o">=</span> <span class="kp">nil</span>
<span class="c1"># HERE!!!</span>
<span class="vi">@mon_mutex</span><span class="p">.</span><span class="nf">unlock</span>
<span class="k">end</span>
<span class="k">end</span>
</code></pre>
<p>It breaks the state of the monitor and it causes deadlock.</p>
Ruby master - Bug #15164 (Closed): mkmf doesn't work with miniruby on Windows
https://redmine.ruby-lang.org/issues/15164

naruse (Yui NARUSE)
naruse@airemix.jp
<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.
</code></pre>
<p>Note that recent Windows sets PATH to paths under %APPDATA% for example<br>
C:\Users<UserNameInANSI>\AppData\Local\Microsoft\WindowsApps</p>

<p>Dev meeting <em>IS NOT</em> a decision making place. All decisions should be done at the bug tracker.<br>
Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly.<br>
Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue).<br>
We will write a log about discussion to a file or to each ticket in English.<br>
All activities are best-effort (keep in mind that most of us are volunteer developers).<br>
The date, time and place is scheduled according to when/where we can reserve Matz's time.</p>

Ruby master - Feature #13881 (Open): Use getcontext/setcontext on OS X
https://redmine.ruby-lang.org/issues/13881
2017-09-08T09:10:50Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>getcontext/setcontext is first appeared on OS X 10.5 but deprecated on 10.6.<br>
It seems because POSIX removed them from recent specs.</p>
<p>IEEE Std 1003.1, 2004 Edition says makecontext's use of function declarators with empty parentheses<br>
is an obsolescent feature.<br>
<a href="http://pubs.opengroup.org/onlinepubs/009695399/functions/makecontext.html" class="external">http://pubs.opengroup.org/onlinepubs/009695399/functions/makecontext.html</a></p>
<p>Then POSIX.1-2008 removed those functions.</p>
<p>But OS X 10.13 still has them maybe because some essential applications uses them for co-routines.<br>
Therefore we can use them for performance.</p>

Ruby master - Feature #13873 (Closed): Optimize Dir.glob with FNM_EXTGLOB
https://redmine.ruby-lang.org/issues/13873
2017-09-05T17:51:27Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>Rails often queries Dir.glob with complex pattern.</p>
<p>On accessing Rails site, it calls glob as follows on querying templates.<br>
Note that Dir[] insists File::FNM_EXTGLOB.</p>
<pre><code class="ruby syntaxhl" data-language="ruby"> <span class="k">def</span> <span class="nf">find_template_paths</span><span class="p">(</span><span class="n">query</span><span class="p">)</span>

<span class="k">end</span>
<span class="k">end</span>
</code></pre>
<p><a href="https://github.com/rails/rails/blob/6f1c18308ebffc97d51440cdeed7be71de58f26a/actionview/lib/action_view/template/resolver.rb#L247" class="external">https://github.com/rails/rails/blob/6f1c18308ebffc97d51440cdeed7be71de58f26a/actionview/lib/action_view/template/resolver.rb#L247</a></p>
<p>For example on accessing index page of Post Model (/posts), it calls following glob:<br>
Dir["/home/naruse/foo/app/views/posts/index{.en,}{.html,.text,.js,.css,.ics,.csv,.vcf,.png,.jpeg,.gif,.bmp,.tiff,.svg,.mpeg,.xml,.rss,.atom,.yaml,.multipart_form,.url_encoded_form,.json,.pdf,.zip,.gzip,}{}{.raw,.erb,.html,.builder,.ruby,.coffee,.jbuilder,}"]'</p>
<p>It calls many stat as follows:</p>
<pre><code>% sudo strace ./miniruby58882 -e'Dir["/home/naruse/foo/app/views/posts/index{.en,}{.html,.text,.js,.css,.ics,.csv,.vcf,.png,.jpeg,.gif,.bmp,.tiff,.svg,.mpeg,.xml,.rss,.atom,.yaml,.multipart_form,.url_encoded_form,.json,.pdf,.zip,.gzip,}{}{.raw,.erb,.html,.builder,.ruby,.coffee,.jbuilder,}"]'|&grep newfstatat|wc -l
400
</code></pre>
<p>Because current glob implementation handles braces in early stage,<br>
then calls stat for each combination of brace patterns instead of using readdir results.</p>
<p>Below is a patch to use readdir instead of hundreds of syscalls.<br>
Note that this patch changes the order of the result as follows:</p>
<pre><code> 1) Failure:
TestDir#test_glob [/home/naruse/ruby/test/ruby/test_dir.rb:157]:

Ruby master - Feature #13869 (Open): Filter non directories from Dir.glob

<p>Dir.glob is a tool to fetch filesystem entries with filtering.</p>
<p>On Rails, it often query files from template directories with braces (FNM_EXTGLOB)<br>

<p>By this code, File.directory?() will call lstat(2) system call for each files.</p>
<p>But if Dir.glob is extended, it can avoid calling lstat because it can fetch entry's type from struct dirent<br>
(on many platforms).</p>

<p>クラッシュログは自分で走らせてもらうとして、何が起きているかというと、<br>
(1) 文字列リテラルをはじめとして、何らかのかたちでシンボルを作らずにrb_fstringからfrozenなStringを作る<br>
(2) その文字列に対してsingleton_classを呼ぶ。するとそのRVALUE->klassにsingleton_classが代入される<br>
(3) 同じ内容の文字列でString#internする(1.でシンボルを作っているとlookup_str_sym()にひっかかる)<br>
(4) register_fstringの"assert(RBASIC_CLASS(ret) == rb_cString);"で落ちる</p>

<p>How about Git-style commit message instead of ChangeLog?</p>
<a name="Proposal"></a>
<h2 >Proposal<a href="#Proposal" class="wiki-anchor">¶</a></h2>
<p>After we reach the consensus</p>
<ol>
<li>Write a commit message in Git-style.</li>
</ol>
<ul>
<li>Line 1: summary of commit (around 80 characters or less, <50 is better)</li>
<li>Line 2: empty line</li>
<li>Line 3-: More detailed explanation of commit</li>

<li>Stop manually edit ChangeLog and auto-generate on <code>make dist</code>.</li>
</ol>
<a name="Rationale"></a>
<h2 >Rationale<a href="#Rationale" class="wiki-anchor">¶</a></h2>
<p>A good commit message should include the objective of the commit.<br>
Committers should write "what purpose the change is for".<br>
In this sense, ChangeLog is not a good format. It lists per-file changes, so committers tend to write just "how the files were changed".</p>
<p>Also, ChangeLog causes commit conflicts frequently.<br>
Though it is not related with the actual commit.<br>
People who uses svn/git should see the log with it; ChangeLog is only for tarball users.</p>
<a name="Status"></a>
<h2 >Status<a href="#Status" class="wiki-anchor">¶</a></h2>
<p>mame made this proposal at the developers' meeting (13 Apr.), and there was no objection.</p>
<p>Matz agreed with this proposal, provided that a ChangeLog-like plain-text file is generated from the commit log.<br>
The release manager will create the file when Ruby is released.</p>

<p>How about adding encodeURIComponent/decodeURIComponent compatible API?</p>
<p>There's already have some methods:</p>
<ul>
<li>URI.escape: context aware but deprecated.</li>
<li>URIencode_www_form: application/x-www-form-urlencoded, which encodes spaces into '+'</li>
<li>URIencode_www_form_component: above component</li>
</ul>
<p>So it doesn't have non-form URI escape method.</p>

Ruby master - Feature #11218 (Closed): File.open FILE_SHARE_DELETE
https://redmine.ruby-lang.org/issues/11218
2015-06-04T05:19:41Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>fluentdという、OSSのログコレクタがあるのですが、これには<code>in_tail</code>プラグインというものがあります。<br>
これは、ログファイルを監視して、ログがファイルに追記されたらその分を読み込んでJSONにして他に流します。</p>
<p>このログファイルはfluentdではない他の誰か、ApacheだったりRailsだったりします。<br>
この手のログファイルを書いていく流儀はいくつかありますが、ご存じの通りRailsやApacheは基本的に特定のパスにひたすら追記し続け、<br>
それでは肥大化しすぎるのでlogrotateなどと組み合わせて適宜rotateしていく運用が一般的でしょう。<br>
つまり、ログファイルをrenameし、ApacheやRailsなどにsignalで再起動して新しいファイルに書くわけです。</p>
<p>ところで、Windowsは誰かが開いているファイルをrenameすることはできないので通常このようなことは出来ません。<br>
やるにはファイルを開く際の<code>CreateFile</code>に<code>FILE_SHARE_DELETE</code>フラッグをつけてやる必要があります。<br>
そんなことやってる人いるのかというご指摘もあるとは思いますが、やる人はやっているようです。<br>
<a href="https://issues.apache.org/jira/browse/HADOOP-8564" class="external">https://issues.apache.org/jira/browse/HADOOP-8564</a></p>
<p>さて、RubyのWindowsの<code>open(2)</code>ラッパー、<code>rb_w32_open</code>/<code>rb_w32_wopen</code>はテキストモードの場合は<code>_open</code>/<code>_wopen</code>を使っており、<br>
これはおいておくとして、バイナリモードの場合は<code>CreateFile</code>を使っているものの現状<code>FILE_SHARE_DELETE</code>は渡していないので、<br>
なんらかの手段で<code>FILE_SHARE_DELETE</code>を付けられるようになりませんか。</p>
Ruby master - Feature #11216 (Closed): inode for Windows
https://redmine.ruby-lang.org/issues/11216
2015-06-03T13:32:22Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>現在WindowsではFile::Stat#inodeは常に0を返しますが、<br>
例えばあるlogrotate的な運用の行われるファイルを監視・開きっぱなしにして、追記されれば差分を読み、<br>
rotateされた場合は検出して最新のログを読む…というような場合に、rotateを検出する際にinodeは使われます。</p>
<p>WindowsにはGetFileInformationByHandle()というAPIで得られるBY_HANDLE_FILE_INFORMATION構造体のメンバ、<br>
nFileIndexHigh/Lowから64bitのファイルシステムuniqueなIDがあるので、これをinodeとして代用が可能です。</p>
<p>問題はこれをFile::Statにいれるにはもとのstruct stat.inoが16bitで小さすぎる点ですが、<br>
幸いstruct stati64にはアライメントの都合で隙間があるため、そこにつっこむことにしています。<br>
(devとudevが常に同じとか、uidやgidが常に0など無意味な値は他にもありますが)<br>

Ruby master - Bug #10397 (Closed): gcc 4.1.2 for x86 can't build trunk

<p>Recently CentOS 5.6 x86 can't build ruby-trunk.<br>
This is since r47562 and it hit <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=16185" class="external">gcc bug</a>.</p>
<p>Do people want CRuby to continue RHEL/CentOS 5.6 support?<br>
If so, ideally it is fixed by gcc.</p>

<p>拡張子のない Ruby スクリプトファイルを require する手段を提供しませんか。</p>
<p>Rubyスクリプトを拡張子無しで書くことはしばしばあります。<br>
例えば Unix のコマンドを Ruby で書くときがそうでしょう。</p>
<p>そのスクリプトの部品を将来再利用しそうなとき、場合によっては if $0 == <strong>FILE</strong> ハックを用いて、<br>
他のファイルから読み込まれたときはコマンドを起動を行わないようにするわけですが、<br>
拡張子がないとそもそも読み込めないので、まずファイル名を変えないといけません。</p>
<p>という具合で残念な感じなので、拡張子無しのファイルを読み込む手段を提供しませんか。<br>
require_relative は拡張子無しでも読める、辺りがいいと思うのですが。</p>
Ruby master - Feature #9816 (Assigned): 文字列内の数字を数値として比較するメソッド

2014-05-08T09:37:26Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>文字列内の数字を数値として比較するメソッドを追加しませんか</p>
<p>そのような比較は一般的な用途としてはGUIシェルのファイラーが比較に用いており、<br>
Windows では StrCmpLogicalW が、OS X では NSString:compare:options:へのNSNumericSearch定数が提供されています。<br>
<a href="http://msdn.microsoft.com/en-us/library/windows/desktop/bb759947(v=vs.85).aspx" class="external">http://msdn.microsoft.com/en-us/library/windows/desktop/bb759947(v=vs.85).aspx</a><br>
<a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/c/econst/NSNumericSearch" class="external">https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/c/econst/NSNumericSearch</a></p>
<p>上記のような処理自体はさほど難しいものではありませんが、Rubyレベルで実装すると大量のオブジェクトを作ってしまいます。<br>
例えば <code>Gem::Version.new("2.1.10".freeze)<=>Gem::Version.new("2.1.9".freeze)</code> は47個、<br>
<code>"2.1.10".freeze.split('.').map(&:to_i)<=>"2.1.9".freeze.split('.').map(&:to_i)</code> だと16個のオブジェクトを作ります。<br>
<code>"2.1.10".freeze.numericcmp"2.1.9".freeze</code> ならば、もちろんオブジェクトは一つも作りません。</p>
<p>なお、上記の例でも示唆していますが、本メソッドは Ruby のバージョン表記の TEENY が2桁になった場合の比較に用いることができます。</p>
<p>パッチは以下の通りです。<br>
なお、メソッド名は String#numericcmp としています。<br>
(String#casecmpを念頭に置いた)</p>

そもそも editline の readline wrapper は non ASCII に対応していません。<br>

<p>Legacy Ruby 1.8 could regexp match with broken strings.<br>
People can find characters from binary data on the age.</p>

<p>If you test rb_iter_break() with some extension library like trunk's ext/-test-/iter/break.c, it will cause SEGV on 1.9.3.<br>
It won't happen on 2.0 because r34369 is accidentally fix it with below patch.</p>
<p>I noticed this because RubySpec added a test for rb_spec_iter (4db31b04954118e66ac1d6353ebf4106cb2b419b) and hit this.</p>

Ruby master - Feature #6936 (Closed): Forbid singleton class and instance variabls for float

<p>[Feature <a class="issue tracker-2 status-5 priority-4 priority-default closed" title="Feature: Introduce Flonum technique to speedup floating computation on th 64bit environment (Closed)" href="https://redmine.ruby-lang.org/issues/6763">#6763</a>] などで議論されていた flonum が r36798 でが入ったわけですが、</p>
<ol>
<li>Float のオブジェクトID の仕様が変更</li>
<li>flonum な float に特異メソッドが追加不可</li>
<li>flonum な float に特異クラスが作成不可</li>
<li>flonum な float は同じ値同士でインスタンス変数が共有される</li>
</ol>
<p>といった非互換が存在します。<br>
もっとも、1. は通常意識するはずのないところですし、2. は元から禁止されています。<br>
気になるのは 3. と 4. で、これは 1.9.3 と挙動が異なるだけでなく、<br>
32bit 環境での 2.0 や、64bit環境の flonum でない float オブジェクトとも挙動が異なります。</p>
<p>実際問題として実害はないような気もしますが、このような違いが極めて実装上の問題で、<br>
Ruby 上から見えないところに存在するのは気持ち悪く感じます。</p>
<p>よって、以下のようにするとよいのではないでしょうか。</p>
<ul>
<li>flonum でない float でも特異クラスの作成を禁止</li>
<li>float へのインスタンス変数作成を禁止</li>
</ul>
<p>後者の具体的手法はいくつかあると思いますが、即値は最初から frozen にしておくとかもありかなと思っています。</p>
<p>話を発散させると、この話は true, false, nil, Fixnum, Symbol のような即値から、<br>
Bignum や Time のような immutable っぽいオブジェクトにも当てはまる気がしています。</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 #5813 (Closed): net/http's EOFError and Keep-Alive
https://redmine.ruby-lang.org/issues/5813

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>

<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>

<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>

Backport193 - Backport #5757 (Closed): main threadがreadやselectで待っていると、^C でなかなか死なない

<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>

<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>

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>

Ruby master - Feature #4089 (Closed): Add addr2line for C level backtrace
https://redmine.ruby-lang.org/issues/4089
2010-11-26T09:22:36Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>=begin<br>
最近の Ruby は SEGV や BUG 時に Ruby level backtrace を出したり、<br>
取れるときは C level backtrace を出したりしています。</p>
<p>ところが、C level backtrace だけ見ても実のところあまり助けにならないことが多いので、<br>
ソースコードのファイルや行数も可能ならば出したいところです。</p>
<p>などと言っていたら浜地さんがパッチを作ってくれたので、これを取り込みませんか。<br>
glibc 環境 (つまり Linux) や、libexecinfo を導入している FreeBSD や NetBSD など (のELFなバイナリ) で動きます。</p>

Ruby master - Feature #3947 (Closed): Array#packのにエンディアン指定修飾子</>を追加
https://redmine.ruby-lang.org/issues/3947

<p>=begin<br>
Ruby の伏魔殿 Array#pack ですが、機種依存な部分をいじる際にはしばしば強力かつ唯一の手段になる事があります。<br>
具体的には RubySpec 書く時とか。</p>
<p>さて、pack のようにバイト列を扱う場合、しばしば問題になるのがエンディアンです。<br>
ここで、Ruby の Array#pack は 16bit/32bit 固定の整数に対してはエンディアン固定の<br>
n/N/v/V 指定子を用意していますが、short/int/long/long long のように、<br>
マシン依存の型をエンディアン固定で pack する手段を提供していません。<br>
というわけで、これが欲しいです。</p>
<p>ここで問題になるのがどのように指定するかなのですが、pack のネタ元である Perl さんでは既に </> 修飾子を<br>
この目的のために提供しています。<br>
<a href="http://perldoc.perl.org/functions/pack.html" class="external">http://perldoc.perl.org/functions/pack.html</a><br>
というわけで、これに追従するのがよろしいと思います。</p>
<pre><code> > sSiIlLqQ Force big-endian byte-order on the type.
jJfFdDpP (The "big end" touches the construct.)
< sSiIlLqQ Force little-endian byte-order on the type.
jJfFdDpP (The "little end" touches the construct.)
</code></pre>
<p>なお、「</> とかきもい」という意見もあるかとは思いますが、pack は機種依存とかに触るきもいメソッドなので、<br>
そこを気にするよりは長い物に巻かれておいた方が無難ではないかなと思うため、</> 修飾子がベストかと思います。<br>

Ruby の伏魔殿 Array#pack ですが、機種依存な部分をいじる際にはしばしば強力かつ唯一の手段になる事があります。<br>
具体的には RubySpec 書く時とか。</p>
<p>さて、q/Q は 64bit signed/unsigned int なのですが、機種依存の long long (厳密には LONG_LONG) のサイズが必要な場合、<br>
現状 Ruby レベルから取る手段が一切ありません。<br>
すでに s/S/i/I/l/L (16bit/32bit/32bit) は、! をつけることでその機種の short/int/long のサイズになるため、<br>
これを q/Q に拡張すると唯一の手段が提供される事になります。</p>
<p>というわけで、Array#packのqQ指定子に機種依存サイズフラグ!を追加したいです。<br>

<p>これらに共通するのは「Errno::ECONNRESET: Connection reset by peer」という例外が発生している点です。<br>
この例外は socket の close(2) を呼んだ際に errno に ECONNRESET がセットされたときに発生します。<br>
しかし、この挙動は POSIX 仕様外であり、FreeBSD 独自のものです。</p>

Ruby master - Feature #2579 (Closed): Net::HTTP.start("www.ruby-lang.org", use_ssl: true) で SSL 利...

<p>=begin<br>
従来、Net::HTTP で https アクセスをするためには</p>
<p>http = Net::HTTP.new("www.ruby-lang.org", 443) # port を指定<br>
http.use_ssl = true # use_ssl を true に<br>
http.verify_mode = OpenSSL::SSL::VERIFY_PEER # デフォルトだと検証してくれないので変更<br>
http.start{|h| } # やっと本題<br>
http.finish # 破棄</p>
<p>などとする必要がありました。</p>
<p>この提案では、Net::HTTP(addr, opt){..} という呼び出し方を追加します。<br>
opt はハッシュで、アクセサのある項目を設定する事が出来ます。</p>
<p>なお、折角の新 API なので、この API を使った場合、verify_mode のデフォルトが VERIFY_PEER になっています。<br>
つまり、この API を用いた場合デフォルトで SSL 署名の有効性を検査するため、<br>
期限切れやオレオレ証明書の場合例外が出ます。</p>
<p>これにより、さっきのは以下のように書けます。<br>
Net::HTTP.start("www.ruby-lang.org", use_ssl: true){|h| }</p>
<p>P.S.<br>
なお、以上の例で用いている <a href="http://www.ruby-lang.org" class="external">www.ruby-lang.org</a> は、現在 SSL 証明書が期限切れのため、<br>
この例を今実行すると検証に失敗して例外が出ます。<br>
今は StartCom とかだと無料で 主要環境でルート証明書が入っている Web サーバ用の SSL 証明書が取得できますから、<br>
そういうのに入れ替えた方がいいのではないでしょうか。<br>

現在 net/https はほとんど抜け殻で、ほぼ require 'openssl' するためだけに存在するのですが、<br>
残っているロジックも net/http に移してしまって、net/http だけで https も扱えるようにしませんか。<br>
autoload を使って https に実際にアクセスしたときに openssl ライブラリをロードするようにしたので、<br>
無駄に読み込むこともありません。</p>
<p>なお、net/https は require を使うままにしているので、こちらだともし openssl ライブラリがない場合、<br>
net/https ロード時にエラーが出るという現在の挙動をそのまま利用できます。<br>

Ruby master - Feature #2032 (Closed): Change the license to "GPLv2+ or Ruby's original".

This is moved ticked from ruby-dev.<br>
Original post and ticket is <a class="issue tracker-2 status-5 priority-4 priority-default closed" title="Feature: Change the license to "GPLv2+ or Ruby's original". (Closed)" href="https://redmine.ruby-lang.org/issues/2000">#2000</a> in English.</p>
<p>----- Original Post -----</p>
<p>Hello.</p>
<p>Recently readline 6.0 was released and its license was changed from<br>
GPLv2+ (GPL version 2 and any later) to GPLv3+ [1][2]<br>
Unfortunately Ruby's license is still under GPLv2 and Ruby's original license [3],<br>
which is incompatible with GPLv3 [4]. So unless Ruby's license is changed<br>
to "GPLv2+ or Ruby's original license" or so , Ruby's readline module cannot be shipped<br>
any more. Note that "Ruby's original license" is regarded as incompatible with<br>
GPL [5].</p>
<p>So please change the Ruby's license to GPLv3 (and GPLv2) compat.</p>

Ruby master - Feature #1951 (Closed): openのBOM指定拡張
https://redmine.ruby-lang.org/issues/1951
2009-08-18T23:47:15Z
naruse (Yui NARUSE)
naruse@airemix.jp
<p>#747と#802で議論された、openのBOM指定拡張ですが、現在の仕様は、</p>
<ul>
<li>BOMを捨てる</li>
<li>BOMを見てencodingを設定する<br>
という2つの機能が混在しています。</li>
</ul>
<p>このために、たとえば「<code>UTF-8-BOM</code>」という指定でも、<br>
BOMがUTF-16LEを示していた場合には実際に返ってくるStringはUTF-16LEになってしまいます。</p>
<p>この問題に対する解決案として、</p>
<ul>
<li>UTF-*-BOM はBOMを捨てるだけ。別のencodingだった場合は例外</li>
<li>
<code>BOM|UTF-*</code>を追加、これが現在の<code>UTF-*-BOM</code>相当の動作 (BOMを見る OR <code>UTF-*</code>と指定、というイメージ)<br>
というものを考えています。</li>
</ul>
<p>皆さんはどのように思われますか?</p>
Backport191 - Backport #1938 (Closed): FreeBSDでmakeに失敗する

<p>=begin<br>
common.mkに$(YACC) -d $(YFLAGS) -o y.tab.c $(<:=/)という行がありまして、<br>
これはLinuxとかWindowsでは動くんですが、BSD makeだとバックスラッシュがエスケープだと解釈され、<br>
「Unclosed substitution for < (= missing)」<br>
というエラーが出ます。</p>
<p>この問題はr22964で対処されています。<br>

<p>=begin<br>
FreeBSD 7.1-PRERELEASE amd64 にて、SIGQUIT を無視してしまうようです。</p>
<ol>
<li>Failure:<br>
test_status_kill(TestProcess) [test/ruby/test_process.rb:941]:<br>
Expected ["#<Process::Status: pid 53404 SIGQUIT (signal )>",<br>
"#<Process::Status: pid 53404 SIGQUIT (signal ) (core dumped)>"].include?(*["#<Process::Status: pid 53404 exit 0>"]) to return true.</li>
</ol>
<p>書き換えると以下の通り</p>
<p>% cat wait.rb<br>
sleep 10;<br>
print "finished\n";<br>
% ruby19 -e'pid=spawn("ruby19","wait.rb"); Thread.new{sleep 3; Process.kill(:SIGQUIT, pid) }; Process.wait(pid);;p $?'<br>
finished<br>
#<Process::Status: pid 53220 exit 0></p>
<p>なお、spawn("perl" に書き換えるとちゃんと殺せます<br>

<p>printf("%c", codepoint) という解釈になりますので、<br>
