This is a known bug that only affects IMAP connections and the software developers have stated it will be addressed in a forthcoming version. If you enable diagnostic logging in eM Client, you should find the following entry in the log file:Ģ1:20:57.389|053| Greetings * OK Calzada Media () IMAPv4 Cause & SolutionĪt this time, we believe this issue is being caused by a bug in the software that powers our mail services. Under the Log tab, you may see entries of MailExceptions.ConnectionExceptions followed immediately by (Connection Terminated) ResponseWriter, r * http.If you use " title="eM Client">eM Client to access our standard POP3/IMAP email accounts, you may occasionally get the error message stating Connecting to mail account failed (see screenshot below). Create an HTTP server that listens on port 8000 If the request gets cancelled before that, we want to return immediately:

So, to listen for a cancellation event, we need to wait on <- ctx.Done().įor example, lets consider an HTTP server that takes two seconds to process an event. This returns a channel that receives an empty struct type every time the context receives a cancellation event. The Context type provides a Done() method.

Emitting the cancellation event Listening For Cancellation #.

There are two sides to context cancellation: Now that we know why we need cancellation, let’s get into how you can implement it in Go.īecause “cancellation” is highly contextual to the operation being performed, the best way to implement it is through context. Ideally, we would want all downstream components of a process to halt, if we know that the process (in this example, the HTTP request) halted: Without cancellation, the application server and database would continue to do their work, even though the result of that work would be wasted: The timing diagram, if everything worked perfectly, would look like this:īut, what would happen if the client cancelled the request in the middle? This could happen if, for example, the client closed their browser mid-request. In short, we need cancellation to prevent our system from doing unnecessary work.Ĭonsider the common situation of an HTTP server making a call to a database, and returning the queried data to the client:

Let’s talk about cancellation first: Why Do We Need Cancellation? # Miscellaneous data required at every function call invoked by the operation.Cancellation signals to terminate the operation.

Using the Context data type is the idiomatic way to pass information across these kind of operations, such as: Advertisements

Cancellation signals whe performing async operations using goroutines.

Errors when fetching data from a database.

Request IDs for function calls and goroutines that are part of an HTTP request call.

Advertisements When Do We Use Context? #Īs the name suggests, we use the context package whenever we want to pass around “context”, or common scoped data within our application. We will also go through some patterns and best practices when using the context package in your Golang application. In this post, we’ll learn about Go’s context package, and more specifically, how we can use cancellation to improve our applications performance.
