Writing to ch1 will not immediately cause the select operation to continue. The goroutine can be scheduled after the channel write or after the close operation so both cases have a chance to run. If ch1 was unbuffered then write operation would only happen after channel read so the program would always print ch1.

Just catch the exception and move on.

The problem is not in the double backslashes, since the 'r' before your path is correctly doing its job escaping them. The problem is in the '.

Try using just

Try this.

You can use a regular expression to find ID attribute in each .cdm file (or the lxml package what should be better). I also replaced os.walk by pathlib.glob. Here the code:

As mentioned here https://github.com/spring-projects/spring-boot/issues/25049#event-4265028906

Inject the RestTemplate (or better, RestOperations) in the class's constructors (this is best practice anyway), and for the classes where you need the proxy configuration, use an @Bean configuration method to instantiate the bean and pass the specific proxied template.

Yes, this is the expected behavior, OOTB.

Most Apache Geode processes (clients (i.e. ClientCache), Locators, Managers and "peer" Cache nodes/members of a cluster/distributed system) only create daemon Threads (i.e. non-blocking Threads). Therefore, the Apache Geode JVM process will startup, initialize itself and then shutdown immediately.

Only an Apache Geode CacheServer process (a "peer" Cache that has a CacheServer component to listen for client connections), starts and continues to run. That is because the ServerSocket used to listen for client Socket connections is created on a non-daemon Thread (i.e. blocking Thread), which prevents the JVM process from shutting down. Otherwise, a CacheServer would fall straight through as well.

You might be thinking, well, how does Gfsh prevent Locators (i.e. using the start locator command) and "servers" (i.e. using the start server command) from shutting down?

NOTE: By default, Gfsh creates a CacheServer instance when starting a GemFire/Geode server using the start server command. The CacheServer component of the "server" can be disabled by specifying the --disable-default-server option to the start server command. In this case, this "server" will not be able to serve clients. Still the peer node/member will continue to run, but not without extra help. See here for more details on the start server Gfsh command.

So, how does Gfsh prevent the processes from falling through?

Under-the-hood, Gfsh uses the LocatorLauncher and ServerLauncher classes to configure and fork the JVM processes to launch Locators and servers, respectively.

By way of example, here is Gfsh's start locator command using the LocatorLauncher class. Technically, it uses the configuration from the LocatorLauncher class instance to construct (and specifically, here) the java command-line used to fork and launch (and specifically, here) a separate JVM process.

However, the key here is the specific "command" passed to the LocatorLauncher class when starting the Locator, which is the START command (here).

In the LocatorLauncher class, we see that the START command does the following, from the main method, to the run method, it starts the Locator, then waitsOnLocator (with implementation).

Without the wait, the Locator would fall straight through as you are experiencing.

You can simulate the same effect (i.e. "falling straight through") using the following code, which uses the Apache Geode API to configure and launch a Locator (in-process).

You can use the optional chaining operator (?.). It will short-circuit and return undefined in case you try to access a property on null or undefined.
