Messages are not logged in order

[sapir1779]

I'm using modern-syslog version 1.1.4, OS: Ubuntu 18.04.1 LTS.

The below program generates out-of-sync log messages:

const syslog = require('modern-syslog');
setInterval(function(){ 
    syslog.log(syslog.LOG_INFO, "1");
    syslog.log(syslog.LOG_INFO, "2");
    syslog.log(syslog.LOG_INFO, "3");
    syslog.log(syslog.LOG_INFO, "4");
}, 3000);

The expected sequence is NOT always "1, 2, 3, 4", but rather a permutation of 1,2,3,4 (e.g., "1,4,2,3").

Perhaps I'm missing something and when you mentioned "async" in the description this is what you meant but otherwise this is major.

Yes, that's what async means. You're basically sending four log messages in parallel; first past the post wins, so to speak.

If you want to sequence them, use callbacks or promisify and async/await them.

I'm going to close this as answered. If there's reason to reopen, let me know.
