Can't send mail from ofApp::exit()

[Echolaitoc]

I'm trying to send a log of my application when it shuts down.
So I added the following to ofApp::exit():

smtp.send(message);
smtp.waitForThread();

But the application closes before sending the mail.

When I try waiting for the thread without stopping it, the mail gets send but the application freezes and never closes:

smtp.send(message);
smtp.waitForThread(false);

I found a workaround

// in ofApp.h
bool waitForMail;

and

smtp.send(message);
waitForMail = true;
while (waitForMail)
{
    // do nothing
}

and on receiving a SMTP delivery event in ofApp::onSMTPDelivery(ofx::SMTP::Message::SharedPtr& message) setting

waitForThread = false

Is this intendet behaviour? I expected either my first or second approach would have worked. I'm kind of unhappy with my current solution (a while loop with nothing in it...).

Ah, interesting situation.

So, the smtp client registers its own exit() listener, which tells the thread to quit and then it waits for the thread and exits. But if by some chance your ofApp::exit is called before it is finished, it saying smtp.waitForThread won't have an effect because it hasn't been told to stop yet.

The only solution I can think of (without modifying ofxSMTP to have a manual quit function) is to call ofxSMTP's exit frunction from your ofApp exit function like ...

ofApp::exit()
{
    smtp.send(message);
    ofEventArgs args; // just emtpy;
    smtp.exit(args);
    smtp.waitForThread(true);


}

that should (theoretically) shut everything down smoothly ...

Hey, thanks for the quick reply.
Unfortunately I had no luck with your solution. The app closes smoothly, but no mail is sent.
So there is no difference for me in calling or not calling smtp.exit(args)

edit:
By the way, when I call smtp.exit(args) I can call both waitForThread(true) and waitForThread(false) without freezing the app. But it closes regardless and sends no mail.

Any updates on this issue? Perhaps try it with 0.10.0+ and all of my recent updates?

I am no longer working on that project where I used your addon. I ended up keeping my workaround with

while (waitForMail)
{
    // do nothing
}

I'll see if I can whip up a bare project to only test this issues.

edit:
I can't get the examples to work anymore. For the basic gmail example Google always marks my mails 550 High probability of spam and doesn't send them. For the advanced example I'm getting
[ error ] "Client::threadedFunction: Certificate validation error : Certificate validation error: Unacceptable certificate from [my mail server]: application verification failure"
I'm sorry but I'm to busy to look further into this.
