Panicked with `Parse(Unexpected("MailboxData(Recent(1))"))` #81

kper · 2018-07-17T14:04:20Z

Hello!

I wrote a minimal example of my code, which works totally fine when only one guy sends an email. However, when I try to send an email from two different email addresses to server at the same time, my server panics.

Cargo.toml

[package]
name = "imap_test"
version = "0.1.0"
authors = ["Kevin Per <[email protected]>"]

[dependencies]
imap = "0.8.1"
native-tls = "0.1" 
mailparse = "0.6.2"

main.rs:

extern crate imap;
extern crate mailparse;
extern crate native_tls;

use imap::client::Client;
use native_tls::{TlsConnector, TlsStream};
use std::net::TcpStream;

use mailparse::*;

fn main() {
    let domain = "";
    let email = "";
    let password = "";


    let socket_addr = (domain.clone(), 993);
    let ssl_connector = TlsConnector::builder().unwrap().build().unwrap();
    let mut imap_socket =
        imap::client::Client::secure_connect(socket_addr, domain.clone(), &ssl_connector)
            .unwrap();

    imap_socket
        .login(email, password)
        .unwrap();

    loop {
        match imap_socket.select("INBOX") {
            Ok(mailbox) => {
                println!("{}", mailbox);
            }
            Err(e) => println!("Error selecting INBOX: {}", e),
        };

        let mut unseen = imap_socket
            .run_command_and_read_response("UID SEARCH UNSEEN 1:*")
            .unwrap();

        // remove last line of response (OK Completed)
        unseen.pop();

        let mut uids = Vec::new();
        let unseen = ::std::str::from_utf8(&unseen[..]).unwrap();
        let unseen = unseen.split_whitespace().skip(2);
        for uid in unseen.take_while(|&e| e != "" && e != "Completed") {
            if let Ok(uid) = usize::from_str_radix(uid, 10) {
                uids.push(format!("{}", uid));
            }
        }

        uids.reverse(); //latest first

        for uid in uids.iter() {
            let raw = imap_socket.uid_fetch(uid, "RFC822").unwrap(); //here it panics!

            for message in raw.iter() {
                let m = message.rfc822();

                if m.is_none() {
                    continue;
                }

                let parsed = parse_mail(m.unwrap()).unwrap();

                let subject = parsed.headers.get_first_value("Subject").unwrap().unwrap();
                let from = parsed.headers.get_first_value("From").unwrap().unwrap();

                if parsed.subparts.len() > 0 {
                    let body = parsed.subparts[0].get_body().unwrap();

                    println!("From: {}", from);
                    println!("Subject: {}", subject);
                    println!("Body: {}", body);
                }
            }
        }
    }
}

jonhoo · 2018-07-17T15:57:37Z

Hmm, I wonder if this is a bug in imap-proto. Perhaps @djc can shed some light on it?

djc · 2018-07-18T12:46:32Z

@jonhoo can you tell me what the Parse(Unexpected()) part is? Ideally I'd like to see the on-the-wire data, which would make it a bit easier to troubleshoot this.

kper · 2018-07-18T15:42:04Z

Is there a good way to capture the on-the-wire-data?
I tried to capture it with Wireshark, unfortunately all imap servers I know are using ssl, therefore is everything encrypted and I have no idea how to extract the key.
https://serverfault.com/questions/360259/cant-decrypt-imaps-traffic-in-wireshark

djc · 2018-07-18T16:12:50Z

SSLKEYLOGFILE (https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/Key_Log_Format) can help depending on what TLS library you are using, and Wireshark can consume the resulting file. Otherwise you could insert some println!() calls in imap or imap-proto...

jonhoo · 2018-07-18T16:20:30Z

Actually, on a closer look, I think this errors stems from here, which suggests that the UID FETCH returns something this is not a Response::Fetch. Specifically, from the error you're giving, it gets a Response::MailboxData(Recent(1)) instead, which seems really odd?

A wire data trace would come in very handy here!

EDIT: keep in mind that you may want to remove the LOGIN part of the request to hide your password :)

djc · 2018-07-18T17:09:30Z

Reading the RFC, I think this might be an untagged (unsolicited) server message. That is, I think the assumption that you'll only get FETCH responses in response to a FETCH command is wrong.

jonhoo · 2018-07-18T17:26:15Z

What makes you say that? 6.4.5 says:

Responses:  untagged responses: FETCH

Which I take to mean that you should only get FETCH responses?

kper · 2018-07-18T18:16:56Z

Thanks!

Here is the ssl stream from wireshark (I hope it is ok, that I posted it as comment, if you prefer I can export it)

Strangely, I get another error message today

@kper you can probably remove some of the intermediate

a38 SELECT "INBOX"
* OK [CLOSED] Previous mailbox closed.
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.
* 18 EXISTS
* 0 RECENT
* OK [UIDVALIDITY 1531815609] UIDs valid
* OK [UIDNEXT 56] Predicted next UID
a38 OK [READ-WRITE] Select completed (0.001 + 0.000 + 0.001 secs).
a39 UID SEARCH UNSEEN 1:*
* SEARCH
a39 OK Search completed (0.001 + 0.000 secs).

segments to make it harder to read. This seems like a different issue though? Specifically, here you get Parse(Invalid([])), whereas previously you got a Parse(Unexpected(...))?

The Parse(Invalid([])) I comes from here when parsing this response:

a56 UID FETCH 19 RFC822
a56 OK Fetch completed (0.001 + 0.000 secs).

and I have a fix in mind for this that I'll push shortly.

Partial fix for #81.

jonhoo · 2018-07-18T20:15:24Z

@kper can you try with dea9398 ? Won't fix the Unexpected, but should fix the Invalid, which might give us a trace for the Unexpected :)

kper · 2018-07-19T03:52:31Z

Great! Thanks, the minimal example seems to run fine again :)

jonhoo · 2018-07-19T03:57:35Z

Hmm, that's so weird. This shouldn't fix the Unexpected you were seeing :/

kper · 2018-07-19T04:11:56Z

I can't even explained why the error message changed - same emails, same server, same code

I'll run the patch on my test server for a few days. Let's see if I get any error message. If not I will close this issue after the weekend.

Huge thanks to you guys!

kper · 2018-07-21T15:46:36Z

Ok, I managed to to reproduce the error from before. I replied on an email from the server several times, waited until the server printed it out and then replied again. This leads to the error:

jonhoo · 2018-07-21T16:05:29Z

Interesting... It looks like the response to your last FETCH:

a151 UID FETCH 74 RFC822

starts with

* 37 FETCH (UID 74 RFC822 {5034}
Return-Path: <[email protected]>
...
)

which is all good, but is then followed by:

* 1 RECENT

before it ends with

a151 OK Fetch completed (0.010 + 0.000 + 0.009 secs).

@djc from the RFC, I don't believe this is possible. AFAICT, only untagged FETCH responses should be sent in response to a FETCH command? Have you seen RECENT being returned as well?

jonhoo · 2018-07-21T16:06:23Z

Ahh, on further inspection of Section 7:

An example of unilateral untagged server data occurs when the IMAP
connection is in the selected state. In the selected state, the
server checks the mailbox for new messages as part of command
execution. Normally, this is part of the execution of every command;
hence, a NOOP command suffices to check for new messages. If new
messages are found, the server sends untagged EXISTS and RECENT
responses reflecting the new size of the mailbox. Server
implementations that offer multiple simultaneous access to the same
mailbox SHOULD also send appropriate unilateral untagged FETCH and
EXPUNGE responses if another agent changes the state of any message
flags or expunges any messages.

jonhoo · 2018-07-21T16:30:21Z

@kper can you confirm that 72925cf indeed fixes the issue?

kper · 2018-07-21T16:41:54Z

Looks good to me :)
Thanks

jonhoo · 2018-07-21T17:17:48Z

@mattnenterprise this also requires a release, or #69.

djc · 2018-07-21T20:36:18Z

@jonhoo nice find! I figured it was something like that.
