Keyword "Apache Spark" shows up on Warehouse as two keywords "Apache", "Spark"

Here’s how I set my project’s keywords (ref):

keywords=['Apache Spark'],

So my intention was 1 keyword, “Apache Spark”. However, here on Warehouse this shows up as two keywords, “Apache” and “Spark”.

Is this intentional?

I know that setup() also accepts a single string for keywords, instead of a list of strings, as follows:

keywords='Apache Spark',

In this case I would expect the keywords to be interpreted as whitespace-delimited – that is, two keywords, “Apache” and “Spark”, as they currently are on Warehouse.

I think that if you use keywords="Apache Spark," you might get the behavior you want, but yea, closing this as WONTFIX. Thanks!

This seems to be the doing on format_tags filter.

https://github.com/pypa/warehouse/blob/master/warehouse/filters.py#L101

Specifically

L108: split_tags = re.split(r'\s+', tags)

I think the correct behavior is this:

• If passed argument tags is a list, then call format_tags recursively (or iteratively), to clean each individual one.
• If tags is a string, then execute the existing flow.

Legacy pypi doesn’t seem to be doing any formatting - just dumps the keyword as a string on the UI.

@dstufft or @rjwebb can confirm.
