gh-109276: regrtest: shorter list of resources

[vstinner]

• Issue: Enhance Python regrtest test runner (test.libregrtest) #109276

[vstinner]

Examples:

$ ./python -m test -u network
== resources (1): network

$ ./python -m test --slow-ci
== resources: all

$ ./python -m test --fast-ci
== resources: all, -cpu


$ ./python -m test -u all,tzdata
== resources: all, +tzdata

$ ./python -m test 
== resources: all test resources are disabled, use -u option to unskip tests

@serhiy-storchaka: Does it look better like that?

[serhiy-storchaka]

I did not have problems with the older output, but if you want to change it, the new one looks better.

Did you consider the idea of making it compatible with the input to the -u option? I.e. remove space after comma and remove plus sign. Alternatively you can make -u accepting input with spaces and pluses (although copying text with spaces is less convenient). Not that I personally need this feature, but it might come in handy one day.

Done.

Use sorted() for deterministic result.

Done.

Suggested change

	relative_all.append(f'{name}')
	relative_all.append(name)

[vstinner]

Oh right. Sadly, I saw your comment after the change was merged. I make try to include it in my next regrtest change ;-)

For me, it's not easy to know if it's default --slow-ci option, default --fast-ci option, or if -u options were modified on a buildbot. With the new output relative to -u all, it should be easier to guess the test config.
