bug#42827: 27.1; ~/Emacs file not read at init

[Tomasz Kowalski]

Hi there,

Emacs ignores ~/Emacs file at startup. Below are the relevant lines 
from strace:
--------------------------------------------
openat(AT_FDCWD, "/home/tomaszen_AU.utf8/Emacs", O_RDONLY) = -1 ENOENT
(No such file or directory)
openat(AT_FDCWD, "/home/tomaszEmacs", O_RDONLY) = -1 ENOENT (No such
file or directory)
uname({sysname="Linux", nodename="schooner", ...}) = 0
--------------------------------------------
"/home/tomaszEmacs" should clearly be "/home/tomasz/Emacs" and
"/home/tomaszen_AU.utf8/Emacs" should
be "/home/tomasz/en_AU.utf8/Emacs"

Forgotten / somewhere? 

Best regards,

Tomasz

Hmm. Any chance of catching that in gdb so we can see where itʼs being
called from?

I can confirm:

[pid 2320398] openat(AT_FDCWD, "/home/larsien_US.UTF-8/Emacs", O_RDONLY) = -1 ENOENT (No such file or directory)
[pid 2320398] openat(AT_FDCWD, "/home/larsiEmacs", O_RDONLY) = -1 ENOENT (No such file or directory)

I'm not certain, but I think the problem might well be your upper case
"E" at the beginning of the file name.  I think you also want a ".",
giving a name like

    /homt/tomasz/.emacs

.  Hope that helps!

Looks like the bug was added in commit 900276502f.

This is the Emacs application file under X, not the configuration
file. Iʼd be worried if we looked for .emacs by trying to append a
locale string to $HOME :-)

Yes, get_homedir doesnʼt stick a '/' on the end, and gethomedir did.

If someone can confirm that this fixes it, I can push to master or to
emacs-27, whichever is preferred (personally I donʼt think itʼs a
major bug, but it is a regression).

If the fix is confirmed, please install on emacs-27.

Thanks.

I confirmed that your patch fixes the bug that I unfortunately introduced, and I 
installed your patch to emacs-27 in your name. Thanks for the patch, and thank 
you too Tomasz and Andreas for the report and diagnosis.
