Hello maintainers, Glenn,
[This popped up with Glenn's idea for a fix to bug#29187 (which I
commited in 0da08f2f8ef1946978f0974e9e8cdb87fece018c). It's breaking an
interactive run of the flymake tests (which run fine with make check).]
I find, to my surprise that evaluating this form returns nil
(let* ((tempdir (make-temp-file "some-temp-dir" t))
(process-environment (cons (format "HOME=%s" tempdir)
process-environment))
(absolute (concat "/home/"
user-login-name
"/foo.txt")))
(string= absolute
(with-current-buffer
(find-file-noselect absolute)
buffer-file-name)))
Same with find-file. find-file is unexpectedly prepending my absolute
file name with HOME found in the process environment.
It returns t, as expected, when:
* when the process-environment override is removed;
* emacs is started with HOME=/nonexistent, as is the case with
make check;
* very curiously, if the absolute file name is *not* prefixed by
whatever HOME was before the override;
Thanks,
João
