I think that there is a problem with this commit, in that the default
selector is only used for "make check". By default "make check-maybe"
runs all tests (including the expensive ones). So, you have to do

make check-maybe SELECTOR="(quote (not (tag :expensive-test)))"

I think it makes more sense for check-maybe to skip expensive tests,
unless told otherwise, as "make check-maybe" is a good candidate for use
pre-commit.

Something like this should work:


SELECTOR_DEFAULT=(quote (not (tag :expensive-test)))
SELECTOR_EXPENSIVE=nil
SELECTOR=
ifeq ($(SELECTOR),undefined)
SELECTOR_ACTUAL=$(SELECTOR_DEFAULT)
else
SELECTOR_ACTUAL=$(SELECTOR)
endif

(and changing all subsequent uses of SELECTOR to SELECTOR_ACTUAL).


which would preserve the use of "SELECTOR" for use on the command line.

Make sense? (er, pun not intended).

Hi Phillip, we need to get all of this straightened out, let me know so that I
can reflect the same changes into master, in order to repair what was lost of
this work during yesterdays' merge.

I believe Philip is not speaking about a problem of the merge from
yesterday. It's about my original commit to the emacs-25 branch.

Best regards, Michael.

I see. Before touching the Makefile, we shall agree how all the targets
shall behave. I would say, that "check" and "check-maybe" shall skip the
expensive tests. "check-expensive", "<foo>", and "<foo>.log" shall run
all tests.

I've committed the patch to the emacs-25 branch.

Best regards, Michael.

Yep, no worries about the merge. Michael's change went in a while back.

Sorry for slow reply!

I would say that, yes, both check and check-maybe should skip expensive
tests by default. I think this actually contradicts the GNU coding
standards, but possibly it's these that need updating for very slow
tests.

I'd also agree about <foo>, <foo>.log (on master <foo>.log is
lisp/<foo.log>, and lisp/<foo> also exists).


However, I also think that these should also respond to setting
SELECTOR on the command line.

The problem with this patch:


+SELECTOR_DEFAULT = (quote (not (tag :expensive-test)))
+SELECTOR_EXPENSIVE = nil
+SELECTOR =

+check-maybe:
+	@${MAKE} check-doit SELECTOR="${SELECTOR_DEFAULT}"
+


is that "make check-maybe SELECTOR=nil" doesn't actually run the
expensive tests as it should. That was the reason for my original,
rather more complicated, suggestion.

I've attached a complete patch below (actually tested this time!), which
I think works. Would this make sense to you?

Yes, go for it. Please describe it also somewhere.
