Michael,
The (relatively) recently added test in files-tests.el fails on
MS-Windows:

If you could tell a bit regarding why the expression
(with-temp-buffer (insert-directory nospecial-dir ""))
is supposed to signal an error here, I could look into the possible
reason(s).
Thanks.

That is rather tricky. We have two macros for every files-tests-file-name-non-special-<foo> test: `files-tests--with-temp-non-special' and `files-tests--with-temp-non-special-and-file-name-handler'. The first macro is rather a straight forward test. In case of `files-tests-file-name-non-special-insert-directory', it does something like (house-keeping stripped off): --8<---------------cut here---------------start------------->8--- (let* ((temporary-file-directory (file-truename temporary-file-directory)) (tmpdir (make-temp-file "files-tests" t)) (nospecial-dir (file-name-quote tmpdir))) (should (equal (with-temp-buffer (insert-directory nospecial-dir "") (buffer-string)) (with-temp-buffer (insert-directory tmpdir "") (buffer-string))))) --8<---------------cut here---------------end--------------->8--- The second macro adds an additional file name handler `files-tests--special-file-name-handler', which cares about files with trailing ".special" in their name, and which removes this part of the file name, if they are not quoted. This is done just to see, whether this file name handler has been invoked (which shouldn't for quoted file names). So this part in the `files-tests-file-name-non-special-insert-directory' test expands to --8<---------------cut here---------------start------------->8--- (let* ((temporary-file-directory (file-truename temporary-file-directory)) (file-name-handler-alist `((,files-tests--special-file-name-regexp . files-tests--special-file-name-handler) . ,file-name-handler-alist)) (tmpdir (concat (make-temp-file "files-tests" t) files-tests--special-file-name-extension)) (nospecial-dir (file-name-quote tmpdir))) (should-error (with-temp-buffer (insert-directory nospecial-dir "")))) --8<---------------cut here---------------end--------------->8--- The idea is to check, that once a file name has been quoted with the leading "/:", no other file name handler comes in play. In the given example, a directory "/tmp/files-testsdItXI0" is created, and tmpdir gets the value "/tmp/files-testsdItXI0.special". (insert-directory tmpdir "") would work because the file name handler removes the trailing ".special" from tmpdir. (insert-directory nospecial-dir "") should raise an error, because the file name handler is not invoked, and nospecial-dir does not exist. This works fine under GNU/Linux. Luckily, I have a Windows machine under control today. Running the second snippet under edebug, I get: --8<---------------cut here---------------start------------->8--- c:/Users/albinmic/AppData/Local/Temp/files-testsKpFOvs.special: doesn’t exist or is inaccessible Test failed: ((should-error (edebug-after (edebug-before 17) 21 (with-temp-buffer (edebug-after (edebug-before 18) 20 (insert-directory (edebug-after 0 19 nospecial-dir) ""))))) :form (edebug-after 17 21 nil) :value nil :fail-reason "did not signal an error") --8<---------------cut here---------------end--------------->8--- `insert-directory' has shown a bug, but it doesn't signal an error. This seems to be the problem, and maybe also for the other failed tests you have presented. And indeed: --8<---------------cut here---------------start------------->8--- (insert-directory "c:/dir/does/not/exist" "") => nil --8<---------------cut here---------------end--------------->8--- But no error is signaled. Under GNU/Linux, I have --8<---------------cut here---------------start------------->8--- (insert-directory "/dir/does/not/exist" "") => Debugger entered--Lisp error: (file-missing "Reading directory" "No such file or directory" "/dir/does/not/exist") --8<---------------cut here---------------end--------------->8--- > Thanks. Best regards, Michael. PS: Thanks to Noam, who has written all these boring files-tests, which uncover the problems now.
