bug#23423: 25.0.93; Opening file from the command line stays in *GNU Emacs* buffer

[Jan Synáček]

Steps to reproduce:
1) Install emacs and run 'emacs <any file>' from the command line.

The file is opened, but you have to switch to its buffer because, for
some reason, the splash screen stays as the current buffer. You can work
around this by running emacs with '--no-splash'.

Expected behavior is to switch to the file's buffer and not to stay
in the *GNU Emacs* buffer.

I cannot reproduce this.  I get either the file's buffer alone in its
frame, or a 2-window frame with file displayed in the selected window,
and the splash screen in the other one.

Are you sure it's not some of the customizations that run from your
~/.emacs or site-start file?

​I can reproduce the problem when running '​
emacs -q --no-site-file
​file'.

I'm trying this on Fedora Rawhide with emacs built without any patches.
However, there seems to be a bug in gtk3 that makes emacs start
in a very small window, which cannot be split. Might that be the problem?
When I run 'emacs -q --no-site-file
​file -mm file', I *sometimes* get the split
and sometimes see only the splash screen.

It turns out that the gtk bug I was referring to was an incompatibility and was
fixed in emacs git [1]. And it also turns out that my original bug report is not
reproducible with the patch applied. However, I still think that the
buffer should
be visible in case emacs is run with the splash screen and the window is so
small that it cannot be split.

Thanks for telling us.

I disagree, sorry.  The extremely small frame you were getting is the
result of the bug that was already fixed, so I see no reason to cater
to buggy behavior anymore.

To be so small that it cannot be split, the window has to be
ridiculously small. Eg it is still split for me with an unusable

emacs --geometry 10x10 README

So in practice, there is no issue.

It had a really small height. I filed this more or less for the record.
