[PATCH] org-test: Fix wrong-numbre-of-arguments error on master+native-comp

[Ihor Radchenko]

Running make test on master using Emacs master compiled with native-comp
support throws error:

decode-time((22352 22528) nil nil)
  time-to-days((22352 22528))
  org-time-stamp-to-now("2016-06-03 Fri")
  org-deadline-close-p("2016-06-03 Fri" 0)
  apply(org-deadline-close-p ("2016-06-03 Fri" 0))

As discussed in Emacs bug#48133, this is because of outdated cl-letf
statement in org-test. The attached patch is fixing the problem.

Best,
Ihor

Subject: [PATCH] org-test: Fix wrong-numbre-of-arguments error on
 master+native-comp

* testing/org-test.el (org-test-at-time): Use correct number of
arguments in 'decode-time cl-letf binding. `decode-time' accepts up to
3 arguments on master.

The wrong-numbre-of-arguments error is raised on Emacs master
configured with native-comp support when running make test on Org mode
master.  Native-comp modifies function calls with optional arguments
in the way that omitted arguments are still provided as `nil'.  For
example, `decode-time' called as (decode-time time) in lisp source may
be compiled into (decode-time time nil nil) call by native-compiler.
If redefined `decode-time' does not accept 3 arguments, it result in
error.

See Emacs bug#48133.
