spawnl和waitpid [英] spawnl and waitpid
问题描述
你好，
我在Apache下运行一个python cgi脚本...
当脚本运行时我想显示a请等待
消息，直到脚本完成。
我试图这样做，但是请等待消息出现在
脚本末尾（此时没用！）
这里我的脚本：
--- -------------------------------------------------- -------------------------------------------
def get_ret（状态）：
signal = status& 0xff
如果信号== 0：
retcode = status> 8
else：
retcode = 0
返回信号，重新编码
pidActuel = os.spawnl（os.P_NOWAIT，" c：\\python25 \
\ python.exe"，" python"，" Main.py"）
if（get_ret（os.waitpid（pidActuel，0））[1] == 0）：
print"""结束"
else：
print"""请稍等..."""
--------------------------- -------------------------------------------------- --------------------
i忘了...
感谢您的帮助:)

打印消息后应刷新sys.stdout，或者
消息将保留在缓冲区中，直到缓冲区已满或处理
终止。

你好
感谢您的回答
i有这样的冲洗，但结果相同..服务器等到
结束...
pid = os.spawnl（os.P_NOWAIT，& ; c：\\python25 \
\\ python.exe"，" python"，" Main.py"）
sys.stdout.flush（）
ret = os.waitpid（pid，0）
if（ret [1]！= 0）：
print"""等待％i""" ％ret [1]
sys.stdout.flush（）
else：
print"""结束％i""" ％ret [1]
sys.stdout.flush（）
hello,
I run a python cgi script under Apache...
and while the script is running i want to display a "please wait"
message until the script finish.
I have tried to do this but the "please wait" message appears at the
script end (which is useless at this time! )
here my script:
------------------------------------------------------------------------------------------------
def get_ret(status):
signal = status & 0xff
if signal == 0:
retcode = status >8
else:
retcode = 0
return signal,retcode
pidActuel = os.spawnl(os.P_NOWAIT,"c:\\python25\
\python.exe","python","Main.py")
if ( get_ret(os.waitpid(pidActuel,0))[1] == 0 ):
print """ END"""
else:
print """ please wait... """
-------------------------------------------------------------------------------------------------
解决方案
i forgot ...
thanks for any help :)

You should flush sys.stdout after you print messages, or
the message will keep in buffer untill buffer is full or process
terminated.

end...
pid = os.spawnl(os.P_NOWAIT,"c:\\python25\
\python.exe","python","Main.py")
sys.stdout.flush()
ret = os.waitpid(pid,0)
if ( ret[1] != 0):
print """ wait %i """ %ret[1]
sys.stdout.flush()
else:
print """ end %i """ %ret[1]
sys.stdout.flush()
