From 4c6c327d0c66a21416ed1b5e9738b7dd13e739f2 Mon Sep 17 00:00:00 2001 From: Glenn Morris Date: Tue, 18 Dec 2018 21:18:31 -0500 Subject: [PATCH] Restrict downcasing in elisp xref tests (bug#25534) The tests happen to not fail at the moment because find-library-name now has an extra feature, find-library--from-load-history, which happens to do a case-insensitive regexp match; but still it seems better not to rely on this. * test/lisp/progmodes/elisp-mode-tests.el (xref--case-insensitive): New variable. (xref-elisp-test-run, emacs-test-dir): Only downcase if the filesystem seems to be case-insensitive. --- test/lisp/progmodes/elisp-mode-tests.el | 28 ++++++++++++++++++------- 1 file changed, 20 insertions(+), 8 deletions(-) diff --git a/test/lisp/progmodes/elisp-mode-tests.el b/test/lisp/progmodes/elisp-mode-tests.el index 941e85bc890..97148efde41 100644 --- a/test/lisp/progmodes/elisp-mode-tests.el +++ b/test/lisp/progmodes/elisp-mode-tests.el @@ -298,6 +298,16 @@ ))) +;; tmp may be on a different filesystem to the tests, but, ehh. +(defvar xref--case-insensitive + (let ((dir (make-temp-file "xref-test" t))) + (unwind-protect + (progn + (with-temp-file (expand-file-name "hElLo" dir) "hello") + (file-exists-p (expand-file-name "HELLO" dir))) + (delete-directory dir t))) + "Non-nil if file system seems to be case-insensitive.") + (defun xref-elisp-test-run (xrefs expected-xrefs) (should (= (length xrefs) (length expected-xrefs))) (while xrefs @@ -307,11 +317,13 @@ (expected-source (when (consp expected) (cdr expected)))) ;; Downcase the filenames for case-insensitive file systems. - (setf (xref-elisp-location-file (oref xref location)) - (downcase (xref-elisp-location-file (oref xref location)))) + (when xref--case-insensitive + (setf (xref-elisp-location-file (oref xref location)) + (downcase (xref-elisp-location-file (oref xref location)))) - (setf (xref-elisp-location-file (oref expected-xref location)) - (downcase (xref-elisp-location-file (oref expected-xref location)))) + (setf (xref-elisp-location-file (oref expected-xref location)) + (downcase (xref-elisp-location-file + (oref expected-xref location))))) (should (equal xref expected-xref)) @@ -346,10 +358,10 @@ to (xref-elisp-test-descr-to-target xref)." ;; `load-path' has the correct case, so this causes the expected test ;; values to have the wrong case).
