有了上面的继承关系图后,我们解析socketserver就轻松多了,下面,我们从代码开始,慢慢揭开socketserver面纱: import socketserver import struct, json, os class FtpServer(socketserver.BaseRequestHandler): coding = 'utf-8' server_dir = 'file_upload' max_packet_size = 1024 BASE_DIR = os.path.dirname(os...
ulimit -n和limits.conf里最大文件数设定不能超过/proc/sys/fs/file-max的值,这也是搞笑了, /proc/sys/fs/file-max是系统给出的建议值,系统会计算资源给出一个和合理值,一般跟内存有关系,内存越大,改值越大,但是仅仅是一个建议值,limits.conf的设定完全可以超过/proc/sys/fs/file-max 那么可以 总结出一...
