			<content:encoded><![CDATA[<p>Con un <a href="http://mastrodonato.info/index.php/2010/03/ruby-vs-python-vs-windows-vs-linux/">precedente test</a>, avevo riscontrato che JRuby era la massima espressione per quanto riguardava la velocità nell&#8217;eseguire codice ruby, surclassando non solo gli altri interpreti C++ e .Net ma azzardando prepotenti confronti con le ultime due incarnazioni di python. Gli <a href="http://mastrodonato.info/index.php/2010/01/ruby-vs-ruby-vs-python-vs-python/">script</a> erano questi e li ho rispolverati anche per questo nuovo confronto.</p>
<p>Ora che Rails 3 è stato rilasciato ed uno degli interpreti consigliati è il nuovo 1.9.2, ero curioso di osservare come si comporta la release ufficiale: direi davvero niente male!<br />
Questa volta ho ristretto il numero dei partecipanti alle sole versioni installate con <a href="http://rvm.beginrescueend.com/">RVM</a> più un paio di versioni windows: JRuby 1.4.0 ed il più usato 1.8.7 mingw32, giusto per avere un metro di paragone.</p>
<p>Distribuzione Linux: Ubuntu 10.4 64bit<br />
Windows XP 32Bit SP3</p>

			<content:encoded><![CDATA[<p>In questo articolo metterò a confronto le ultime incarnazioni di ruby, con le ultime di python, groovy, php, lua, perl e anche java, per avere un metro di paragone con un linguaggio precompilato. Vedremo, infatti, come si comportano i linguaggi di script applicati alla geometria frattale, più precisamente un algoritmo della famiglia di Mandelbrot.<br />
Navigando, ho trovato un <a href="http://www.timestretch.com/FractalBenchmark.html#4d9e0f15fc1b42420cf3f778c3cccad7">confronto</a> molto interessante ma un pò datato, risale a più di due anni fa. Da allora sono cambiate un pò di cose e ne ho approfittato per fare un aggiornamento anche se non includerò tutti quei linguaggi molti dei quali semi sconosciuti. Questa è l&#8217;occasione per mettere a confronto ruby e python anche nelle loro versioni java e .net, un intenzione che avevo già da un pò di tempo.</p>
<p>Usare un frattale come benchmark è oltretutto comodo: se un tentativo di ottimizzazione non va a buon fine se ne ha subito l&#8217;evidenza ed essendo disegnato in tempo reale, si riesce a percepire la velocità di esecuzione. Il frattale è disegnato in ascii anche perchè l&#8217;utilizzo di librerie esterne ne avrebbe drogato l&#8217;esito.</p>

<p>Questi sono gli script usati per generare il frattale, andavano benissimo quelli di Erik Wrenholt, mi sono limitato a qualche semplice modifica per far funzionare python 3.1 o per migliorare lievemente la già ottima leggibilità in ruby e lua.</p>

<h3>Commenti:</h3>
<p>La velocità di Lua è ormai nota, solamente 5 volte più lento rispetto al codice java compilato, il miglior risultato. La sua semplicità è la sua forza, forse è proprio questo che lo rende così veloce? E&#8217; stato adottato dalla Blizzard all&#8217;interno del gioco World of Warcraft e se l&#8217;hanno fatto loro un motivo ci sarà. Non è ad oggetti o meglio, nativamente non li supporta anche se c&#8217;è il progetto <a href="http://loop.luaforge.net/">LOOP</a> che lo estende a questo modello di programmazione.<br />
Php e Perl non hanno bisogno di commenti.<br />
Tra le versioni C di Ruby e Python è chiaramente avanti quest&#8217;ultimo. Il paragone equo sarebbe la Rb1.8.6 con la Py2.6.2 e la Rb1.9.1 con la Py3.1.1.<br />
La sfida tra le versioni che sfruttalo la Java VM: Groovy, Jython e JRuby, vede in vantaggio quest&#8217;ultimo. Groovy è molto indietro come prestazioni ma il dubbio più grosso che ho è: ma a chi è destinato? Come sintassi non è male ma ruby è ancora più scorrevole e poi ha quel rake che è tanto comodo per tante cose.<br />
Le versioni ruby e python per .Net vede incredibilmente avanti IronPython! Ma che gli hanno messo dentro, la dinamite? Sarà molto interessante esaminare il nuovo framework MVC di ASP.NET da poco arrivato alla versione 1 e che sarà incluso nel framework .Net 4, esistono progetti sia per IronRuby che per IronPython.<br />
Se questo articolo è risultato interessante, forse potrai trovare qualcos&#8217;altro tra gli annunci del mio sponsor, si trova nella colonna a destra, grazie!</p>

			<content:encoded><![CDATA[<p>Il sistema su cui ho eseguito la prova è un portatile: Dell Inspiron 9400 con Centrino Duo, Intel T7200 4Mb Cache 2Ghz (166&#215;12) Ram 2Gb 667Mhz. Si tratta di un sistema fisico Windows XP pro SP3.</p>
<p>Lo <strong>scopo</strong>: verificare lo sfruttamento di più core del processore (due nel mio caso) mettendo a confronto un processo singolo con una doppia esecuzione in contemporanea.</p>
<p>Per fare questo ho utilizzato il bench delle stringhe di un <a href="http://mastrodonato.info/index.php/2009/08/quattro-interpreti-ruby-a-confronto/">articolo precedente</a>.<br />
C&#8217;è da tener presente che nell&#8217;esecuzione del doppio processo, ognuno deve condividere la cpu con il sistema operativo (il carico è sempre al 100%) mentre nel test singolo questo non succede, un core è dedicato al test mentre l&#8217;altro alle altre faccende. Per questo motivo il sistema operativo era privo di antivirus e di altri processi/servizi pesanti.</p>
<p>Cominciamo con il vecchio interprete dell&#8217;oneclick installer:</p>

<h3>Conclusioni</h3>
<p>Non so cosa sarebe successo con altri test ma in questo, <strong>jRuby</strong> è l'unico che ha un carico uniforme sui due core e lo fa costantemente quasi per tutta la durata. Solo alla fine si sposta verso un core ma con più discrezione. Ottima anche la prestazione con i due processi in contemporanea. </p>
<p>Le versioni 1.8.6 e 1.9.1 sono abbastanza allineate e riescono a spartire il carico solo sui test "Add". La prestazione del doppio processo non sarebbe male ma crea qualche difficoltà al sistema (almeno al mio) che ne allunga i tempi.</p>
<p>IronRuby ha qualche problemino con le stringhe già evidenziato in un <a href="http://mastrodonato.info/index.php/2009/08/quattro-interpreti-ruby-a-confronto/">articolo precedente</a>. Ignorando questo, non ha sfruttato il secondo core che è rimasto scarico per tutta la durata. Col secondo core libero, mi sarei aspettato un decremento meno evidente nel test del doppio processo ma così non è stato, questo è strano!</p>
<p>In un prossimo articolo, mi piacerebbe ripetere il test su un server quad core.</p>

			<content:encoded><![CDATA[<p>Non si può negare che la versatilità sia una delle sue caratteristiche; un vero multipiattaforma. Ci sono interpreti per molti sistemi operativi e oltre alla versione classica in C++ abbiamo la valida alternativa di JRuby per il mondo java e infine Ironruby per il framework .NET di Microsoft, arrivato in questi ultimi giorni ad una versione abbastanza matura.<br />
Niente male, pensiamo ai benefici che un&#8217;azienda potrebbe avere: un linguaggio semplice da imparare ma molto potente, ha un ottimo framework (uno su tutti, Rails) per sviluppare rapidamente applicazioni disponibili per esempio nella intranet e in aggiunta a tutto questo, la possibilità di usare le librerie java o .net.</p>
<p>In questo articolo vedremo come si comportano questi quattro interpreti:</p>
<ol>
<li>Ruby 1.8.6 patch 368 aggiornato al 2009-03-31</li>
<li>Ruby 1.9.1 patch 129 aggiornato al 2009-05-12 revisione 23412</li>
<li>jRuby 1.3.1 (ruby 1.8.6p287) 2009-06-15 Client VM 1.6.0 update 14</li>
<li>IronRuby 0.9.0.0 on .NET 2.0.0.0</li>
</ol>
<p>Lo <strong>scopo</strong>: per scoprire le differenze prestazionali principalmente nell&#8217;ambito del singolo interprete. Ci sono metodi e tecniche che portano allo stesso risultato e senza simili test difficilmente si può stabilire qual&#8217;è la pratica migliore.<br />
Nei test che vedremo, mi sono concentrato sulla velocità di elaborazione controllando solo grossolanamente la quantità di memoria utilizzata.</p>
<p>Il <strong>sistema</strong>: La macchina fisica è un Windows XP Professional SP3 32bit con un Intel E7300 dual core con 3Mb di cache e 3,25Gb di ram. </p>
<div id="attachment_111" class="wp-caption aligncenter" style="width: 429px"><img src="http://mastrodonato.info/wp-content/uploads/2009/08/FXP1.PNG" alt="Sistema fisico" title="FXP" width="419" height="534" class="size-full wp-image-111" /><p class="wp-caption-text">Sistema fisico</p></div>
<p>I test giravano su un sistema virtualizzato con MS Virtual PC 2007, os sempre XP Pro, Java SDK 6.14, Framework .NET 3.5 SP1, processore singolo core, memoria 768Mb. Solo il test più pesante sugli hash l&#8217;ho ripetuto con 2Gb.</p>
<p>I <strong>benchmarks</strong> sono divisi in quattro categorie:</p>
<ul>
<li>Stringhe</li>
<li>Numeri</li>
<li>Array</li>
<li>Hash</li>
</ul>
<p>Li ho creati io e si limitano ad eseguire operazioni molto semplici. Alla fine c&#8217;è un totale ma non deve essere inteso come un indice sull&#8217;effettiva prestazione dell&#8217;interprete perchè questa cambia molto in base ai test scelti e quelli che ho utilizzati io non è detto che siano condizioni riscontrate nell&#8217;uso reale.</p>
<h3>Le stringhe</h3>
<p>Questo è il primo script:</p>

<p><strong>Commento</strong>: Per la concatenazione, in tutti i casi prevale l'operatore << mentre includere le variabili nelle stringhe con #{}, sarà forse efficiente come uso di memoria ma in quanto a prestazioni è in coda agli altri. Ironruby fatica con le stringhe, è alto infatti il divario con particolari operatori anche se basterebbe usare << per quasi annullare il divario. Un pò di fatica anche sul ciclo delle righe se confrontato con gli altri tre. Molto bene ruby 1.9.1 con prestazioni simili a Jruby ma un consumo di memoria di soli 5Mb contro 30 della versione java. Anche la versione 1.8.6 non è niente male, ha perso tempo con gsub (soprattutto rispetto a jruby!).</p>

<p><strong>Commento</strong>: Netto miglioramento della versione 1.9.1 che, con i numeri, è tre volte più veloce della 1.8.6. Anche gli altri due non sono male.<br />
<em><strong>16/08/2009</strong>: Mi sono accorto di aver inserito erroneamente il metodo shift (<<) tra gli add.</em><br />
<em><strong>24/08/2009</strong>: Avevo invertito i risultati della 1.8.6 con quelli della 1.9.1... in effetti mi sembravano un pò strani :-p</em></p>

<p><strong>Commento</strong>: Dunque, in questo terzo test è importante spendere qualche parola. Il tempo alto di jruby ed ironruby è dovuto anche al fatto che ho voluto comparare la concatenazione <strong>+=</strong> ed una versione simile, entrambi MOLTO sconvenienti per questi due interpreti, i tempi sono infatti altissimi, basterebbe utilizzare solo l'operatore <strong><<</strong> per avere risultati molto diversi, in ordine: 1.8.6=61 1.9.1=40 jruby=33 e ironruby=60 ...jruby risulterebbe il più veloce.<br />
Un altra curiosità è l'utilizzo del metodo compact, oltre ad essere più elegante è anche più prestazionale del sistema analogo delete(nil) è anche più prestazionale con sensibili differenze in Ironruby.</p>
<h3>Gli Hash</h3>
<p>Lo script per testare gli Hash è il più pesante nell'utilizzo della memoria, sinceramente non era nelle mie intenzioni ma poi ho pensato di tenerlo così per esaminarne gli esiti:</p>

<p><strong>Commento</strong>: JRuby non ha concluso per un errore di out of memory, il processo java è arrivato ad occupare 600Mb nel test dove si effettua un'inversione degli hash, raggiungendo il limite della JVM. Il meno ingordo di memoria è stato ruby 1.8.6 con "soli" 300Mb mentre la 1.9.1 era quasi fisso su 530Mb, non aumentava, come se ci fosse un muro. Non c'era invece per Ironruby che ha superato la barriera dei 600Mb ma con risultati soprendenti, il test dell'inversione in 5 secondi, contro 33 della 1.9.1!</p>
<h3>Rieseguengo il test con 2Gb di ram:</h3>

<p><strong>Commento</strong>: JRuby si blocca al solito test e sempre con un processo di 600Mb, ho quindi alzato il cap di memoria a 1,5Gb e gli ha permesso di concludere ed anche con un buon tempo ma il processo ha raggiunto dimensioni mostruose, ha di poco superato il giga. Ruby 1.8.6 sempre il meno esoso con 300Mb e la 1.9.1 sempre 530Mb. Entrambi hanno tempi alti con l'inversione ed in particolare con il metodo shift al contrario degli altri due. Ironruby ancora il più veloce con un processo che si accorge della maggiore quantità di memoria e ne usa un altro pò arrivando ad allocare quasi 700Mb.<br />
Le delete degli elementi è sempre stata velocissima anche se aumentavo il numero, forse non ho controllato bene che non venisse effettuata in un unica chiamata, comunque mi accontento di questo risultato.</p>
<h3>Conclusioni:</h3>
<p>Ogni interprete ha i propri ambiti dove eccelle, Ironruby quando lo fa, lo fa bene distanziando gli altri. Anche JRuby si è preso i suoi trionfi, forse avevo un pò più aspettative dalla versione 1.9.1 anche se credo non sia un suo demerito bensì sono stati gli altri a migliorare molto negli ultimi mesi. La versione 1.8.6 mi ha ben impressionato in questa sua nuova versione o meglio patch 368, è migliorata molto accorciando le distanze prestazionali con la nuova 1.9, pur non avendo una VM. Inoltre è la versione più equilibrata senza alti nè bassi e c'è da considerare che è ancora la versione più usata, più compatibile e con il maggior numero di gemme.</p>
<p>Spero che questo articolo sia risultato interessante, nel prossimo includerò un confronto con python 2.6.2 e la nuova versione 3.1.1 che mi risulta essere velocissima, hola!</p>

			<content:encoded><![CDATA[<p>In questo articolo vedremo come utilizzare le classi java contenute in un file JAR<br />
Per questo scopo andremo ad utilizzare una simpatica libreria opensource sviluppata dalla Carnegie Mellon University: <a href="http://freetts.sourceforge.net/">FreeTTS</a>.<br />
L&#8217;acronimo TTS significa Text To speech tradotto: &#8220;da testo a voce&#8221;, permette infatti di trasformare un testo in formato audio. Noi la utilizzeremo in un progetto jRuby on Rails per farci leggere il testo che inseriremo nel db.</p>
<p>Nel <a href="http://mastrodonato.info/index.php/2009/07/configurare-un-ambiente-per-jruby-on-rails/">precedente articolo</a>, abbiamo visto come configurare l&#8217;ambiente, partiamo quindi creando la nuova applicazione:</p>
<p><code><br />
C:>rails ProvaFreeTTS<br />
</code></p>
<p>Nella cartella lib (dalla root) creiamo una sotto cartella freetts, scarichiamo il file <a href="http://sourceforge.net/projects/freetts/files/">freetts-1.2.2-bin.zip</a>, scompattiamo il contenuto in una cartella temporanea, copiamo solamente il contenuto della cartella lib (files jar e jsapi) nella cartella appena creata: tua_applicazionelibfreetts.</p>
<p>Ora creiamo l&#8217;interfaccia per il jar:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#008000; font-style:italic;">#libfreetts.rb</span>

<p>Creiamo una semplicissima risorsa &#8220;<em>sentence</em>&#8221; con un solo campo &#8220;<em>body</em>&#8221;</p>
<p><code><br />
C:ProvaFreeTTS>jruby script/generate scaffold sentence body:text<br />
</code></p>
<p>Ora creiamo due nuove operazioni, come ho spiegato approfonditamente in un <a href="http://mastrodonato.info/index.php/2009/06/aggiungere-un-operazione-ad-una-risorsa-in-un-sistema-restful/">precedente articolo</a>.</p>
<p>Iniziamo dal controller aggiungendo in coda:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;">  <span style="color:#008000; font-style:italic;">#appcontrollerssentences_controller.rb</span>

  <span style="color:#9966CC; font-weight:bold;">end</span>
&nbsp;
  <span style="color:#9966CC; font-weight:bold;">def</span> read
    <span style="color:#0066ff; font-weight:bold;">@sentence</span> = Sentence.<span style="color:#9900CC;">find</span><span style="color:#006600; font-weight:bold;">&#40;</span>params<span style="color:#006600; font-weight:bold;">&#91;</span><span style="color:#ff3333; font-weight:bold;">:id</span><span style="color:#006600; font-weight:bold;">&#93;</span><span style="color:#006600; font-weight:bold;">&#41;</span>

<p>Ora andiamo a modificare le viste.<br />
Creiamo un nuovo file, più precisamente un partial dove inseriremo il form dati per la nostra risorsa, in questo modo utilizzeremo lo stesso codice per tutte le operazioni:</p>

#appviewssentenceedit.html.erb
&nbsp;
&lt;h1&gt;Editing sentence&lt;/h1&gt;
&nbsp;
<span style="color:#006600; font-weight:bold;">&lt;%</span>= render <span style="color:#0066ff; font-weight:bold;">@sentence</span> <span style="color:#006600; font-weight:bold;">%&gt;</span>

<p>Infine modifichiamo la lista per richiamare la seconda delle operazioni implementate, read. Sostanzialmente cliccando sulla riga corrispondente leggerà il testo precedentemente memorizzato nel db.</p>
<p>Dobbiamo solamente aggiungere una riga ottenendo questa view:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;">#appviewssentenceindex.html.erb
&lt;h1&gt;Listing sentences&lt;/h1&gt;
&nbsp;
&lt;table&gt;
  &lt;tr&gt;
    &lt;th&gt;Body&lt;/th&gt;
  &lt;/tr&gt;
&nbsp;

<p>Infine andiamo a modificare il routing:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#008000; font-style:italic;">#configroutes.rb</span>
&nbsp;

&nbsp;
<span style="color:#008000; font-style:italic;">#aggiungiamo</span>

<p>Configuriamo il file database.yml, creiamo il db e le tabelle con rake e facciamo partire glassfish come spiegato <a href="http://mastrodonato.info/index.php/2009/07/configurare-un-ambiente-per-jruby-on-rails/">qua</a> (cerca database.yml)</p>
<p>Come abbiamo visto, utilizzare librerie java con jruby on rails è semplicissimo, siamo pronti per far pronunciare al nostro server tutte le frasi più sporcaccione!</p>
<p>Il <strong>progetto completo</strong> potete scaricarlo <a href="http://www.gigasize.com/get.php?d=p4wsyz5z29c">qua</a>.</p>
<p>Per ulteriori approfondimenti c&#8217;è anche questo <a href="http://ruby.html.it/articoli/leggi/3110/jruby-java-e-ruby-insieme/1/">articolo</a>, mentre <a href="http://java.html.it/articoli/leggi/3098/text-to-speech-con-java-e-freetts/1/">questo </a>tratta la libreria FreeTTS in un progetto Java.</p>
<p>Buona continuazione.</p>

			<content:encoded><![CDATA[<p>Nei prossimi articoli utilizzerò jruby 1.3.1 con Rails 2.3.3 e ne approfitto per scrivere due righe su come configurare il sistema.<br />
A proposito, il sistema utilizzato è un windows xp virtualizzato, java sdk 6, glassfish come application server e javadb.</p>
<p>Scarichiamo e installiamo l&#8217;<a href="http://java.sun.com/javase/downloads/index.jsp" target="_blank">sdk java</a>, siamo alla versione 6 update 14.</p>
<p>C&#8217;è anche il download dell&#8217;sdk con netbeans, un ottimo IDE per gestire progetti ruby on rails. Potrebbe essere un occasione per provarlo. Il pacchetto comprende anche l&#8217;application server glassfish V3.</p>
<p>Ora scarichiamo e installiamo <a href="http://www.jruby.org/" target="_blank">jRuby</a>, siamo alla versione 1.3.1.</p>
<p>L&#8217;installazione è semplicissima: scompattiamo lo zip in un percorso del tipo C:\ruby\jruby-131</p>
<p>Andiamo ad impostare le variabili d&#8217;ambiente, tasto destro su &#8220;Risorse del computer&#8221; sul desktop -> &#8220;Proprietà&#8221; -> seleziona il tab &#8220;Avanzate&#8221; -> click su &#8220;variabili d&#8217;ambiente&#8221;.</p>
<ul>
<li>Aggiungiamo alla variabile <strong>PATH</strong> il percorso della cartella bin dove abbiamo installato jruby, per esempio C:\ruby\jruby-131\bin.</li>
<li>Impostiamo la variabile d&#8217;ambiente <strong>JAVA_HOME</strong>.  Nella zona &#8220;variabili di sistema&#8221; -> &#8220;nuovo&#8221; -> come nome &#8220;JAVA_HOME&#8221; come valore il percorso di installazione dell&#8217;sdk per esempio C:\Programmi\Java\jdk1.6.0_14</li>
</ul>
<p>Non è necessario riavviare il sistema operativo, testiamo il risultato:<br />
<code><br />
C:\><strong>jruby -v</strong><br />
jruby 1.3.1 (ruby 1.8.6p287) (2009-06-15 2fd6c3d) (Java HotSpot(TM) Client VM 1.6.0_14) [x86-java]<br />
</code></p>
<p>Eureka! Ora abbiamo jruby, jirb ed il solito gem. <strong>Se nel sistema è presente anche ruby classico è necessario specificare jruby -S</strong> per richiamare gem, utilizziamolo subito per installare rails 2.3.3:<br />
<code><br />
C:\><strong>jruby -S gem install rails</strong><br />

</code></p>
<p>Installiamo l&#8217;adapter jdbc per collegarci a java DB (da ora ometto jruby -S, nel mio sistema non è necessario):<br />
<code><br />
C:\><strong>gem install activerecord-jdbcderby-adapter</strong><br />
Successfully installed activerecord-jdbc-adapter-0.9.1<br />
Successfully installed jdbc-derby-10.4.2.0<br />
Successfully installed activerecord-jdbcderby-adapter-0.9.1<br />

Installing RDoc documentation for jdbc-derby-10.4.2.0...<br />
Installing RDoc documentation for activerecord-jdbcderby-adapter-0.9.1...<br />
</code></p>
<p>Poi installiamo la gemma per glassfish:<br />
<code><br />
C:\><strong>gem install glassfish</strong><br />
Successfully installed rack-1.0.0<br />
Successfully installed glassfish-0.9.5-universal-java<br />
2 gems installed<br />

</code></p>
<p>Siamo pronti, creiamo un nuovo progetto:<br />
<code><br />
C:\>rails ProvaArticolo<br />
</code></p>
<p>&#8230;nel file di configurazione dei db utilizziamo:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#008000; font-style:italic;"># config/database.yml</span>
&nbsp;

&nbsp;

&nbsp;
<span style="color:#008000; font-style:italic;"># Warning: The database defined as 'test' will be erased and</span>

<p>Facciamo partire il server, dal prompt dentro la nostra applicazione:<br />
<code><br />
C:\ProvaArticolo><strong>glassfish</strong><br />
Starting GlassFish server at: 127.0.0.1:3000 in development environment...<br />
Writing log messages to: C:/ProvaArticolo/log/development.log.<br />
Press Ctrl+C to stop.<br />
</code></p>
<p>All&#8217;indirizzo http://localhost:3000/ dovremmo vedere la pagina di benvenuto.<br />
Ora fermiamo il server con Ctrl+C e creiamo il db in ambiente sviluppo:</p>
<p><code>C:\ProvaArticolo><strong>rake db:create</strong><br />
(in C:/ProvaArticolo)<br />
db/development.db already exists</code></p>
<p>Creiamo qualcosa all&#8217;interno del database, iniziamo con la risorsa di rails:<br />
<code><br />
C:\ProvaArticolo>jruby script/generate scaffold article name:string body:text<br />
      create  app/models/<br />
      exists  app/controllers/<br />
      exists  app/helpers/<br />
      exists  app/views/articles<br />
      create  app/views/layouts/<br />
      create  test/functional/<br />
      create  test/unit/<br />
      create  test/unit/helpers/<br />
      create  public/stylesheets/<br />
      create  app/views/articles/index.html.erb<br />
      create  app/views/articles/show.html.erb<br />
      create  app/views/articles/new.html.erb<br />
      create  app/views/articles/edit.html.erb<br />
      create  app/views/layouts/articles.html.erb<br />
      create  public/stylesheets/scaffold.css<br />
      create  app/controllers/articles_controller.rb<br />
      create  test/functional/articles_controller_test.rb<br />
      create  app/helpers/articles_helper.rb<br />
      create  test/unit/helpers/articles_helper_test.rb<br />
       route  map.resources :articles<br />
  dependency  model<br />
      exists    app/models/<br />
      exists    test/unit/<br />
      create    test/fixtures/<br />
      create    app/models/article.rb<br />
      create    test/unit/article_test.rb<br />
      create    test/fixtures/articles.yml<br />
      exists    db/migrate<br />
      create    db/migrate/20090729171105_create_articles.rb<br />
</code></p>
<p>e creiamo la tabella nel db con la migrate:<br />
<code><br />
<strong>C:\ProvaArticolo>rake db:migrate</strong><br />
(in C:/ProvaArticolo)<br />
==  CreateArticles: migrating =================================================<br />
-- create_table(:articles)<br />
   -> 0.0700s<br />
   -> 0 rows<br />
==  CreateArticles: migrated (0.0700s) ========================================<br />
</code></p>
<p>Infine eliminiamo il file index.html da dentro la cartella public e creiamo la route iniziale:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#008000; font-style:italic;">#config\routes.rb</span>
map.<span style="color:#9900CC;">root</span> <span style="color:#ff3333; font-weight:bold;">:controller</span> <span style="color:#006600; font-weight:bold;">=&gt;</span> <span style="color:#996600;">&quot;articles&quot;</span></pre></div></div>

<p>Riavviamo il server e sempre all&#8217;indirizzo http://localhost:3000/ questa volta dovremmo vedere la lista degli articoli.</p>
<p>Se non mi sono dimenticato qualcosa, jruby on rails è pronto, buon divertimento!</p>

			<content:encoded><![CDATA[<p>Eccoci all&#8217;ultimo articolo della serie rivolta ai distruttori di classe e più in generale a come fare per inserire un metodo da richiamare alla fine dell&#8217;utilizzo di una classe.</p>
<p>Nel precedente articolo abbiamo visto come fare per generare un evento in fase di distruzione dell&#8217;oggetto da parte del garbage collector e che richiami un metodo per svolgere le ultimissime operazioni.</p>

</code></p>
<p>Ci sono un pò di differenze rispetto al precedente articolo:</p>
<p>Questa volta il distruttore è richiamato direttamente nel costruttore perchè ho ipotizzato che servisse ad ogni oggetto, l&#8217;alternativa è definirlo come in un esempio precedente, solo per gli oggetti interessati, dopo l&#8217;istanziamento:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;">E.<span style="color:#9900CC;">new</span><span style="color:#006600; font-weight:bold;">&#40;</span><span style="color:#996600;">'xxx'</span><span style="color:#006600; font-weight:bold;">&#41;</span>.<span style="color:#9900CC;">body</span> <span style="color:#9966CC; font-weight:bold;">do</span> <span style="color:#006600; font-weight:bold;">|</span>o<span style="color:#006600; font-weight:bold;">|</span>
  <span style="color:#CC00FF; font-weight:bold;">ObjectSpace</span>.<span style="color:#9900CC;">define_finalizer</span><span style="color:#006600; font-weight:bold;">&#40;</span>o, o.<span style="color:#9966CC; font-weight:bold;">class</span>.<span style="color:#9900CC;">method</span><span style="color:#006600; font-weight:bold;">&#40;</span><span style="color:#ff3333; font-weight:bold;">:finalize</span><span style="color:#006600; font-weight:bold;">&#41;</span>.<span style="color:#9900CC;">to_proc</span><span style="color:#006600; font-weight:bold;">&#41;</span>
  o.<span style="color:#9900CC;">work</span>
<span style="color:#9966CC; font-weight:bold;">end</span></pre></div></div>

<p>Un altra differenza è che questa volta non si associa una procedura creata &#8220;al volo&#8221; ma un metodo di classe, nella definizione della classe è infatti presente un nuovo metodo: self.finalize</p>
<p>Ho inserito una variabile di classe, chiamata anche attributo statico, @@count. E&#8217; in comune con tutte le istanze e nell&#8217;esempio serve per conteggiare gli oggetti della classe E. Nel distruttore viene mostrato il valore per informarci del numero rimanente di oggetti.</p>
<p>Questa volta non è necessario forzare l&#8217;esecuzione del garbage collector in quanto al termine dello script viene fatto in automatico generando l&#8217;evento che richiama il costruttore per ogni oggetto.</p>
<p><em>Ho cercato di semplificare il codice e cosi facendo ho omesso una finezza di ruby che devo però indicarla almeno come nota anche se non c&#8217;entra nulla coi distruttori. Se i metodi da richiamare sono molti si può utilizzare questa sintassi lasciando il codice molto leggibile:</em></p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;">E.<span style="color:#9900CC;">new</span><span style="color:#006600; font-weight:bold;">&#40;</span><span style="color:#996600;">'xxx'</span><span style="color:#006600; font-weight:bold;">&#41;</span>.<span style="color:#9900CC;">body</span> <span style="color:#9966CC; font-weight:bold;">do</span> <span style="color:#006600; font-weight:bold;">|</span>o<span style="color:#006600; font-weight:bold;">|</span>
  <span style="color:#CC00FF; font-weight:bold;">ObjectSpace</span>.<span style="color:#9900CC;">define_finalizer</span><span style="color:#006600; font-weight:bold;">&#40;</span>o, o.<span style="color:#9966CC; font-weight:bold;">class</span>.<span style="color:#9900CC;">method</span><span style="color:#006600; font-weight:bold;">&#40;</span><span style="color:#ff3333; font-weight:bold;">:finalize</span><span style="color:#006600; font-weight:bold;">&#41;</span>.<span style="color:#9900CC;">to_proc</span><span style="color:#006600; font-weight:bold;">&#41;</span>
    <span style="color:#006600; font-weight:bold;">&#91;</span><span style="color:#996600;">'work'</span>, <span style="color:#996600;">'hardwork'</span>, <span style="color:#996600;">'ecc'</span><span style="color:#006600; font-weight:bold;">&#93;</span>.<span style="color:#9900CC;">each</span> <span style="color:#9966CC; font-weight:bold;">do</span> <span style="color:#006600; font-weight:bold;">|</span>method_string<span style="color:#006600; font-weight:bold;">|</span>
        o.<span style="color:#9900CC;">send</span><span style="color:#006600; font-weight:bold;">&#40;</span>method_string<span style="color:#006600; font-weight:bold;">&#41;</span>
    <span style="color:#9966CC; font-weight:bold;">end</span>
<span style="color:#9966CC; font-weight:bold;">end</span></pre></div></div>

<p>Purtroppo non riesco ad utilizzare un metodo distruttore che sia univoco per istanza. Un altro tentativo poteva essere quello di puntare all&#8217;istanza tramite ObjectSpace che tramite il metodo _id2ref restituisce l&#8217;oggetto con id uguale a quello passato come parametro:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#CC00FF; font-weight:bold;">ObjectSpace</span>._id2ref<span style="color:#006600; font-weight:bold;">&#40;</span>id<span style="color:#006600; font-weight:bold;">&#41;</span></pre></div></div>

<p>Sfortunatamente non funziona dall&#8217;interno del distruttore, probabilmente il garbage collector ha già distrutto l&#8217;istanza, questo è un peccato e spero esista un altro sistema che però non conosco&#8230;</p>

			<content:encoded><![CDATA[<p>Nell&#8217;articolo precedente abbiamo visto come creare un metodo che permetta di rilasciare le risorse al termine dell&#8217;utilizzo. Non sempre però è possibile determinare il momento del rilascio, ad esempio quando è legato ad eventi esterni. In questo caso è necessario che il distruttore sia eseguito proprio quando l&#8217;oggetto sia in fase di smaltimento, in automatico.</p>
<p>Con un linguaggio che adopera un garbage collector però bisogna fare molta attenzione per il semplice motivo che non si sa quando verrà eseguita la pulizia e solo in questo momento viene scaturito l&#8217;evento che richiama il metodo distruttore.</p>
<p>Quando distruggiamo esplicitamente un oggetto da codice, valorizzandolo con nil, stiamo solamente indicando l&#8217;intenzione, sarà poi compito del garbage collector analizzare se effettivamente non esiste nessun riferimento a quell&#8217;area di memoria, basta un solo indirizzamento anche involontario (i casi più probabili) per impedirne il rilascio. Poi c&#8217;è l&#8217;incognita di quando tutto ciò verrà fatto.</p>
<p>Riprendiamo l&#8217;esempio precedente con qualche aggiunta al codice:</p>

<p>Se eseguiamo questo script otterremo il seguente output:<br />
<code><br />

Oggetti dopo la pulizia:<br />
</code></p>
<p>La definizione della classe è rimasta identica, questa volta stanzio due oggetti, il primo è identico all&#8217;articolo precedente, per il secondo invece ho ipotizzato che dovesse gestire il rilascio di alcune risorse in un momento x, noi non sappiamo quando si verificherà sappiamo solo che quando avverrà dobbiamo fare in modo che vengano deallocate alcune risorse.</p>
<p>Un esempio concreto è quando si scrive un file mediante un processo esterno, dobbiamo riferire di chiuderlo prima di terminare la nostra applicazione, anche se si verifica qualcosa di inatteso.</p>
<p>Se esaminiamo il secondo oggetto:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;">e2=E.<span style="color:#9900CC;">new</span><span style="color:#006600; font-weight:bold;">&#40;</span><span style="color:#996600;">'Try2'</span><span style="color:#006600; font-weight:bold;">&#41;</span>
e2.<span style="color:#9900CC;">body</span> <span style="color:#9966CC; font-weight:bold;">do</span>
  <span style="color:#CC00FF; font-weight:bold;">ObjectSpace</span>.<span style="color:#9900CC;">define_finalizer</span><span style="color:#006600; font-weight:bold;">&#40;</span>e2, <span style="color:#CC0066; font-weight:bold;">proc</span><span style="color:#006600; font-weight:bold;">&#123;</span><span style="color:#006600; font-weight:bold;">|</span>id<span style="color:#006600; font-weight:bold;">|</span>puts <span style="color:#996600;">&quot;Finalizing #{id}&quot;</span><span style="color:#006600; font-weight:bold;">&#125;</span><span style="color:#006600; font-weight:bold;">&#41;</span>
  e2.<span style="color:#9900CC;">work</span>
<span style="color:#9966CC; font-weight:bold;">end</span></pre></div></div>

<p>Si nota che abbiamo fatto uso della classe ObjectSpace, contenitore di tutte le classi stanziate, per associare la dimissione dell&#8217;oggetto e2 alla proc passata come parametro. Tradotto in parole semplici stiamo dicendo: prima di distruggere l&#8217;oggetto esegui quella procedura.</p>
<p>Se riguardiamo l&#8217;output si può notare un altro l&#8217;utilizzo della classe ObjectSpace:</p>

<div class="wp_syntax"><div class="code"><pre class="ruby" style="font-family:monospace;"><span style="color:#CC00FF; font-weight:bold;">ObjectSpace</span>.<span style="color:#9900CC;">each_object</span><span style="color:#006600; font-weight:bold;">&#40;</span>E<span style="color:#006600; font-weight:bold;">&#41;</span><span style="color:#006600; font-weight:bold;">&#123;</span><span style="color:#006600; font-weight:bold;">|</span>o<span style="color:#006600; font-weight:bold;">|</span>puts <span style="color:#996600;">&quot;Oggetto: #{o.object_id}&quot;</span><span style="color:#006600; font-weight:bold;">&#125;</span></pre></div></div>

<p>E&#8217; possibile esaminare ogni oggetto istanziato e specificando come parametro la classe E possiamo filtrare solo quella che ci interessa (attenzione che senza filtro la lista potrebbe essere molto lunga).</p>
<p>Tornando all&#8217;output: gli oggetti trovati nel contenitore sono due e viene mostrato l&#8217;id di riferimento. Dopo di che vengono distrutti e viene forzata l&#8217;esecuzione del garbage collector con GC.start. In alternativa a questo è anche possibile eseguire il metodo garbage_collect di ObjectSpace</p>
<p>Dopo la pulizia viene generato l&#8217;evento che richiama la proc associata all&#8217;oggetto, quella che nell&#8217;esempio scrive a video: Finalizing 20805910. L&#8217;id dell&#8217;oggetto è passato come parametro al blocco e noi lo mostriamo. Se andiamo a riesaminare il contenitore degli oggetti questa volta non conterrà nessuna istanza della classe E.</p>
<p>Nel prossimo articolo esaminerò l&#8217;utilizzo di metodi distruttori da associare all&#8217;evento di distruzione dell&#8217;oggetto. Tratterò anche la problematica legata alle variabili di istanza.</p>
