groovy regexp

shared by Benx Shen on 14 Jun 07 - Cached
  • Groovy supports regular expressions natively using the ~"pattern" expression
    • Benx Shen
      Benx Shen on 14 Jun 07
       
      Groovy 對於 regexp 的支援有 3 個特殊的表示方式：
      ~"pattern" (create java.util.regex.Pattern)=~ (create java.util.regex.Matcher)==~ (do Matcher.matches() )
  • // lets create a regex Pattern def pattern = ~/foo/ assert pattern instanceof Pattern
  • Groovy also supports the =~ (create Matcher) and ==~ (matches regex) operators.
  • ...6 more annotations...
  • Since a Matcher coerces to a boolean by calling its find method, the =~ operator is consistent with the simple use of Perl's =~ operator, when it appears as a predicate (in 'if', 'while', etc.). The "stricter-looking" ==~ operator requires an exact match of the whole subject string.
  • def matcher = "\$abc." =~ /\$(.*)\./ // no need to double-escape! assert "\\\$(.*)\\." == /\$(.*)\./ matcher.matches(); // must be invoked assert matcher.group(1) == "abc" // is one, not zero
  • def m = "foobarfoo" =~ /o(b.*r)f/ assert m[0][1] == "bar"
  • // lets create a Matcher def matcher = "cheesecheese" =~ /cheese/ assert matcher instanceof Matcher answer = matcher.replaceAll("edam")

      以下是一些 groovy regexp 的程式碼，請特別注意劃線的部份！
  • // fancier group demo matcher = "\$abc." =~ "\\\$(.*)\\." matcher.matches(); // must be invoked [Question: is this still true? Not in my experience with jsr-04.] assert matcher.group(1) == "abc" // is one, not zero

      這裡需要特別注意的是，如果想要使用 matcher.group() 方法，那麼必須先執行 matcher.matches() 方法呼叫（我記得呼叫 find() 也行）。然而，如果是直接使用 groovy 的語法，那麼就可以直接使用 matcher[0][?] 的用法了！

  • 面向對象編程思想的提出已經不是幾年而是幾十年了，考查其思想的變化，一方面是對現有語言的一些評判，另一方面，也算是對前輩計算機科學家的緬懷。 ——題記 Kristen Nygaard在1962年發明的 Simula 語言現在被認同為世界上第一種明確實現面向對象編程中某些"必要"元素（比如 class）的語言。Simula 是從 Algol 發展來的，可以說，是一種增加了 class 這個數據類型的 Algol，並將參數傳遞的默認模式從"按名調用"換成了"按引用調用"，還提出了根據類型確定初始化過程的方法。 從 Simula 的時代開始，科學家們在解決軟件複雜度方面的思路開始"異常開闊"——當然也有資深的老派牛人們不這麼認為。比方說 Peter Norvig，寫了Design Patterns in Dynamic Programming一書來反駁。他認為設計模式早已體現在以 Lisp 為首的一批語言中了，根本不需要什麼面向對象。但我還是跟從偶像 Alan Kay 的觀點。某些時候，把一種特定的編程風格做進語言裡也是必要的。

Preventing Java's java.lang.OutOfMemoryError: PermGen space failure | Eric's Agile Answers - 0 views

*i_comment* exception java memory permgen_space runtime

shared by Benx Shen on 22 May 07 - Cached
  • The "OutOfMemoryError: PermGen space" message is normally encountered during development activites where a long-running JVM is asked to load/unload builds.
  • The message is a symptom of an incomplete garbage collection sweep where resources are not properly released upon unload/restart. There is no shortage of debate (Hibernate forum, Sun forum, Spring Framework forum ) regarding which codebase is responsible for this symptom, but the finger of blame has been pointed at CGLIB, Hibernate, Tomcat, and even Sun's JVM.
  • In my experience, the most pain-free method of resolving this issue is to switch from Sun's JDK implementation to BEA's freely available JRockit implementation.
  • ...1 more annotation...
  • On a recent project utilizing Tomcat 5.5.12 with Hibernate, I was plagued with this PermGen error, at times even experiencing it during web-based unit testing. Since making the switch to JRockit, I have not encountered this issue even once.
  • Benx Shen on 22 May 07
     
    又是一位和我一樣都慘遭 "PermGen Space" 錯誤的開發者了！
    很奇怪，為何會發生這樣的錯誤呢？
    其中這篇文章所提到的技術，恰巧都是我現在所發生問題的架構，像是 Hibernate, Spring, Tomcat 等，還有 Sun JVM.... Orz
    比較特別的是，多數提供的解決方式，都是去調整 JVM 的設定（-XX:MaxPermSize=256m）。這位老兄則是採用了 BEA JRockit 版本的 JVM 解決此問題，他表示至少這招對他是管用的！
    不過，軟體開發很多時候都會發生這種「魔咒」，這種狀況底下，就好像一個並無可醫的人，只好嘗試各種偏方了！

synchronized thread threadlocal 討論

    對於 java synchronized 的機制多所討論，並且發文者 klyuan 提出了不少測試代碼嘗試讓讀者更能夠跟著學習測試，我覺得真的很棒。雖然，他對於 synchronized 和 threadlocal 的見解的確是有些小錯誤，threadlocal 確實不是在解決多執行緒中資源共享的問題，但我想 klyuan 其實是想使用 threadlocal 來解決「多執行緒中非共享資源的保護」問題。

jvm memory permgen_space

shared by Benx Shen on 22 May 07 - Cached
  • 發現很多人把問題歸因於： spring,hibernate,tomcat，因為他們動態產生類,導致JVM中的permanent heap溢出 。然後解決方法眾說紛紜，有人說升級 tomcat版本到最新甚至乾脆不用tomcat。還有人懷疑spring的問題，在spring論壇上討論很激烈，因為spring在AOP時使用CBLIB會動態產生很多類。
  • 於是有人對更基礎的JVM做了檢查，發現了問題的關鍵。原來SUN 的JVM把內存分了不同的區，其中一個就是permenter區用來存放用得非常多的類和類描述。
  • 對這個bug最徹底的解決辦法就是不要用SUN的JDK，而改用BEA的 JRokit.
