如何在win32上調試文件系統「訪問被拒絕」錯誤？

Question

我在與我們的構建腳本時地獄現在：我使用Waf以推動我們的構建過程，一切都進展順利，但在Windows上，我在哪裏期間建立越來越陣性錯誤。

的錯誤總是基本上都是「拒絕訪問」的這種或那種形式的錯誤，與我已經在構建過程中創造，使一些工具來運行和做的工作臨時文件。例如，運行NSIS生成可執行安裝程序之前，我不得不「舞臺」所有必需的文件到構建目錄，並從那裏運行命令。有時候，工作的事情如預期，但其他時候，我得到一個錯誤報道了我抄例如文件之一：

File: failed opening file "Platform\\Win32\\lxml-2.2.1-py2.6-win32.egg

我花了年齡試圖找出什麼問題，但其真的很難，因爲問題是間歇性的。我想的最後一件事是用procmon監控文件系統訪問，試圖追查是什麼導致了訪問錯誤：我知道這個文件是存在的，因此必須是什麼打開了該文件。我在下面包括了相關的輸出，因爲我看不出什麼是錯誤的：Python似乎在NSIS想要打開它之前關閉文件，但是NSIS失敗。任何人都可以對此有所瞭解嗎？這個問題不是孤立的這種情況也給我在那裏產卵子進程與我抄建立目錄中的文件工作其他情況下...

，痕量，該文件已經存在的軌跡開始時。所以別的東西可能會讓它保持開放（例如病毒掃描程序或索引服務）。
