Empty emails sent by llEmail( )

[Domitan Redenblack]

The code below always sends an empty email to me, although checking the gsAgentHistory just before Noon London time shows visitors in the list. Something is emptying the list BEFORE the email is sent.

Any ideas?



    timer ( ) {
        myCheckAgents( ); // Updates visitor list
        
        if (gsCurHour == "12" && gsPrevHour != "12" ) {// report London Noon daily = SLT 4am
            gsPrevHour = gsCurHour; // due to 20 sec delay of email, remember we are sending one
            llEmail( "virtualvisitor99@gmail.com", "Domaine visitors", 
                "Noon report:\n" + gsAgentHistory );
            gsAgentHistory = "";
        }
        
        gsPrevHour = gsCurHour;
        
     }

Adding two llOwnerSays like this

timer ( ) {

    myCheckAgents( ); // Updates visitor list


    if (gsCurHour == "12" && gsPrevHour != "12" ) {// report London Noon daily = SLT 4am

        gsPrevHour = gsCurHour; // due to 20 sec delay of email, remember we are sending one

        llOwnerSay( gsAgentHistory );

        llEmail( "virtualvisitor99@gmail.com", "Domaine visitors",

            "Noon report:\n" + gsAgentHistory );

        llOwnerSay( gsAgentHistory );

        gsAgentHistory = "";

    }

    gsPrevHour = gsCurHour;

}

 tells what?

No idea until I know how gsAgentHistory string is aquired and maintained. One of most common real-time programming errors is in trying to access data which are not there any longer.

can you post the function.... myCheckAgents( ); ....so we can see it?

It's not important really. Just adds string-lines to the string-list of visitors.

[Xiija]

if ..gsAgentHistory...is a list...then you mebbe could change a few things?

 

you could cast the list to a string..

string Visitors = (string)gsAgentHistory;

and then do

"Noon report : \n" + Visitors);

or try...

 

"Noon report:\n" + (string) gsAgentHistory );

 gsAgentHistory = [];

gsAgentHistory is a string separated by newline chars. It's a "list" in English, but it’s a string in LSL.

I use the nomenclature: gs<varName>

for Global String, etc

I have not had any further trouble, but I did note that the string max length for emails from SL is about 3,600 bytes. It could be that I was exceeding this limit.

I would have thought that SL would just truncate the message to 3,600 bytes plus headers etc, but perhaps not.

I will keep a closer watch on this. If the whole message is truncated when it exceeds 3,600 bytes, that's not good.

According to the wiki article on llEmail,

---

The entire message (including the address, subject and other miscellaneous fields) can't be longer than 4096 bytes combined.

Yes, but there is no information on what happens if the message is longer than that. Other functions specify the string will be truncated. This article does not say.

 

Truncated to 4096 is fine. Deleted is not.

Truncating could have the effect of sending your what appears to be an empty message, though.  Try including this snippet from the llEmail wiki page to get rid of a really long header and leave more room for the message itself:

email( string time, string address, string subj, string message, integer num_left ){    if(llGetSubString(address, -19, -1) == "@lsl.secondlife.com")//trim the header        message = llDeleteSubString(message, 0, llSubStringIndex(message, "\n\n") + 1);}

You have two choices:

1. Make LL change the function so it does what you want
2. Make the truncation all by yourself in the script

I think you should do what is easier:smileysurprised::smileyvery-happy:

My comment was intended for the improvement of the Wiki. 

 

I have already taken the first 3,600 chars of gsAgentHistory for the llEmail( ).

We will see if I see any more incidents.
