trac 做代碼比較時“Too many open files”

Trac做代碼比較時候，如果比較的代碼檔案比較多，會出現：

解決方案是把tracopt/versioncontrol/svn/svn_fs.py 裡的get_cotent函數改為：

    def get_content(self):        """Retrieve raw content as a "read()"able object."""        if self.isdir:            return None        pool = Pool(self.pool)        s = core.Stream(fs.file_contents(self.root, self._scoped_path_utf8,                                         pool()))        # The stream object needs to reference the pool to make sure the pool        # is not destroyed before the former.        s._pool = pool        return s



如果是egg安裝方式，需要把trac檔案尾碼名改為zip ，解壓後修改再放到egg裡面
