Try to append instead of write mode:

This is because your ItemProcessorSurveillance implements two interfaces: ItemProcessor and StepExecutionListener but is only registered as an ItemProcessor in the step. It should also be registered as a listener so that beforeStep is called when appropriate to set the stepExecution field.

1. It is the main method, so there is no need to cleanup. When main returns, the program exits. If this wasn't the main, then you would be correct.

2. There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.

3. Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.

Try this event.preventDefault();

I create a variable that points to that saved file. And use js to open the link. And it downloads itself.

Try this in the for loop:

In a streaming pipeline, Dataflow retries work items running into errors indefinitely.

The code itself does not need to have retry logic.

ISO-8859-1 and UTF-8 are both character encodings designed to be compatible with older US-ASCII, for all the standard printable characters, meaning codes 0x20 to 0x7E. These characters include all lower and upper case latin letters with no accent, numeric digits, space and other usual punctuation marks.

When you simply write a file using Java, and any other tool (except for some specific character encodings), there is nothing within the file that indicates how it has been encoded.

The tool you're using with the file command simply tries to take a guess based on the first bytes of the file: it checks if the sequence makes any sense with a predetermined set of character encodings, reports it when it finds one that seems to match.

In your test, you're only using those standard "english" characters, so any encoding compatible with ascii is suitable for reading the file. That's why you get us-ascii as a result.

You'll get a different result if you start using different characters, such as [éÀÖî].

UTF-8, UTF-16 and UTF-32 allow to start the file with a special sequence of bytes called the byte-order mark (BOM), that identifies the file's encoding. You would have to write it yourself before anything else. for UTF-8, the sequence is 0xEFBBBF

That would be:
