errout | Send stderr to stdout , maintaining order | Runtime Evironment library

After some more research, I was finally able to load my manifests from gitlab into jelastic. The problem is probably due to the gitlab configuration. Loading the jps from the gitlab repo doesn't work over https in the settings I have (which I haven't made myself, it's a CI / CD as a service). It works, however, over http.

Sorry I have no better answer than "Works for me" :-) Here are the steps:

• git clone https://github.com/kubernetes/kubernetes.git

• duplicate sample-cli-plugin as test-cli-plugin (this involves fixing import-restrictions.yaml, rules-godeps.yaml and rules.yaml under staging/publishing - maybe not necessary, but it's safer this way)

• change kubectl-ns.go to kubectl-test.go:

subprocess.Popen() executes your new process directly by default. So your code passes some additional arguments < and /path/to/file.txt to the mail executable, which will not yield the expected result.

Redirections like < on unix systems are handled by the shell, not by each individual executable. That's why you want subprocess.Popen() to run your mail command with all the arguments mail as well as the redirection < /path/to/file.txt in a shell instead.

You can do this with the shell=True parameter:

First, a nitpick. The getaddrinfo() code should be incorporated into the initserver() function, and the linked list of socket structures freed (using freeaddrinfo()) after the loop. This makes the code much more maintainable; you want to keep tightly coupled implementations close together.

Exactly what is the difference between these two methods?

Binding to the wildcard address (i.e., using NULL node and AI_PASSIVE flag when obtaining suitable socket descriptions using getaddrinfo()) means the socket is bound to all network interfaces as a set, not to a specific network interface. When you bind to a specific node name, you bind to a specific network interface.

In practice, it means that if additional network interfaces become available at run time, the kernel will consider them when routing packets to/from sockets bound to the wildcard address.

It really should be a choice made by each system administrator, as there are use cases where the service (your application) should listen for incoming connections on all network interfaces, but also other use cases where the service should listen for incoming connections on a specific or some specific interfaces only. A typical case is when a machine is connected to multiple networks. It is surprisingly common for servers. For practical cases, see e.g. how the Apache web server can be configured.

Personally, I would rewrite OP's initServer() function to look something like the following:

There is a relatively simple typo in the getaddrinfo call

Your code fails because a pipe is not a terminal. Many programs will use isatty(3) and alike to detect if the standard input is connected to a terminal and adjust their behaviour depending on the result.

What you can do is to open a pseudo terminal pair using openpty(3) and run the command with the slave duplicated to its standard input, output and error descriptors, and using the master to communicate with it. Unfortunately I have no time right now writing a full solution as it is rather intricate; I've done it ever in Python and it was tricky even there.

It appears to me that output redirection is handled before the variable expansion.

The most obvious way is to handle this within your if statement:

Turns out you need to use bash -c "echo '10.X.X.X sample.acme.com' >> etc/hosts" to make linux parse the input from script extension properly

Your problem stems from the binary type. To match a stored value you should pad the data to be compared, as it shown in the documentation.

Or you can simply use VARBINARY to avoid the hassle.

Besides, your code is awfully duplicated and thus hard as hell to read and maintain. The very idea of exceptions is that you are catching them all once. Also some conditions are useless and you should use not fetchAll() but the fetch method that is appropriate for your task.

And of course, trying to decode not the actual binary value, but its hexdecimal representation displayed by phpmyadmin wouldn't give you any sensible result indeed.

Below is the Minimal, Complete, and Verifiable example you've been asked for. It represents the actual problem and works for anyone who care to run it, as long as correct credentials are provided.
