[Emacs-diffs] feature/gnus-select 59a41b8 107/218: Optimize tramp-tests.


From: Andrew G Cohen
Subject: [Emacs-diffs] feature/gnus-select 59a41b8 107/218: Optimize tramp-tests.el
Date: Fri, 14 Dec 2018 03:35:11 -0500 (EST)

branch: feature/gnus-select
commit 59a41b8c3841b9dc575ba7e4f6236a8d901ed32b
Author: Michael Albinus <address@hidden>
Commit: Andrew G Cohen <address@hidden>

    Optimize tramp-tests.el
    
    * test/lisp/net/tramp-tests.el (tramp--test-expensive-test):
    Make it a defsubst.  Adapt all callees.
    (tramp--test-print-duration): New defmacro.
    (tramp-test11-copy-file, tramp-test12-rename-file)
    (tramp-test21-file-links, tramp--test-special-characters):
    Run some parts only if expensive tests are enabled.  (Bug#30807)
