如何判断imaplib2空闲响应是否是超时造成的

发布于 2024-10-25 06:02:59 字数 1281 浏览 5 评论 0原文

我正在使用 imaplib2 (docs) 与 IMAP 服务器交互。

我正在使用带有超时和回调的空闲命令。

问题是，我看不到任何方法来判断回调是否是由于达到超时而触发的，或者服务器上是否有我需要检查的更改。

我每次都会得到 ('OK', ['IDLE returned (Success)']) 。

以下是两种情况的调试输出：

超时：

15:43.94 MainThread server IDLE started, timeout in 5.00 secs
15:48.94 imap.gmail.com handler server IDLE timedout
15:48.94 imap.gmail.com handler server IDLE finished
15:48.94 imap.gmail.com writer > DONE\r\n
15:49.17 imap.gmail.com reader < DDDM6 OK IDLE terminated (Success)\r\n
15:49.17 imap.gmail.com handler _request_pop(DDDM6, ('OK', ['IDLE terminated (Success)']))

发生了一些事情：

18:41.34 MainThread server IDLE started, timeout in 50.00 secs
19:01.35 imap.gmail.com reader < * 1 EXISTS\r\n
19:01.37 imap.gmail.com handler server IDLE finished
19:01.37 imap.gmail.com writer > DONE\r\n
19:01.59 imap.gmail.com reader < BFCN6 OK IDLE terminated (Success)\r\n
19:01.59 imap.gmail.com handler _request_pop(BFCN6, ('OK', ['IDLE terminated (Success)']))

我错过了什么？

imaplib2 中不存在该功能吗？

原文

I'm using imaplib2 (docs) to interact with an IMAP server.

I'm using the idle command, with a timeout and a callback.

The problem is, I don't see any way of telling if the callback was triggered by the timeout being reached, or if there was a change on the server that I need to check out.

I just get ('OK', ['IDLE terminated (Success)']) every time.

Here's the debug output for both cases:

Timedout:

15:43.94 MainThread server IDLE started, timeout in 5.00 secs
15:48.94 imap.gmail.com handler server IDLE timedout
15:48.94 imap.gmail.com handler server IDLE finished
15:48.94 imap.gmail.com writer > DONE\r\n
15:49.17 imap.gmail.com reader < DDDM6 OK IDLE terminated (Success)\r\n
15:49.17 imap.gmail.com handler _request_pop(DDDM6, ('OK', ['IDLE terminated (Success)']))

Something happened:

18:41.34 MainThread server IDLE started, timeout in 50.00 secs
19:01.35 imap.gmail.com reader < * 1 EXISTS\r\n
19:01.37 imap.gmail.com handler server IDLE finished
19:01.37 imap.gmail.com writer > DONE\r\n
19:01.59 imap.gmail.com reader < BFCN6 OK IDLE terminated (Success)\r\n
19:01.59 imap.gmail.com handler _request_pop(BFCN6, ('OK', ['IDLE terminated (Success)']))

What am I missing?

Does the functionality just not exist in imaplib2?

Piers Lauder（imaplib2 的作者）刚刚在 imaplib2-devel 邮件列表上回答了这个问题。他说：

我认为测试IDLE是否超时的方法是执行：
instance.response('IDLE')
将返回：
('空闲', ['超时'])
如果空闲返回的原因是超时，而不是
其他内容（例如 ('IDLE', [None])）。
我同意这应该被记录下来，所以我将修复 imaplib2.html
文档

Piers Lauder (author of imaplib2) just answered this question on the imaplib2-devel mailing list. He said:

I think the way to test if an IDLE has timed out is to execute:
instance.response('IDLE')
which will return:
('IDLE', ['TIMEOUT'])
if the reason that the idle returned as a timeout, rather than
something else (such as ('IDLE', [None])).
I agree that this should be documented, so I'll fix the imaplib2.html
document
