Subject: 24.3.50; Suppress *Compile-log* buffer during init
Date: Fri, 23 Nov 2012 13:09:46 +0530

When I am starting up my Emacs, I am getting a split window with top
half containing `initial-buffer-choice' and bottom half showing
"*Compile-Log*" contents.

,----
| elisp/bbdb-2.35/lisp/bbdb-com.elc:Warning: Use `with-current-buffer' rather
|     than save-excursion+set-buffer
| .emacs.elc:Warning: reference to free variable `Info-current-file'
`----

Should snippet below /really/ produce a "*Compile-Log*" when /loading/
my .emacs.elc.

Anyways, I need a way to have this "*Compile-Log*" suppressed or buried.
AFAIK, this "split-window-with-compile-log-in-foreground" is a fairly
recent behaviour with the trunk.

This is not a new problem, actually.  Even if it didn't happen earlier,
it's not because byte-compiler's warnings have changed, but because
some change either causes a code to be byte-compiled which wasn't before.

My guess is that the changes in advice.el have as a side consequence
that your advice now gets compiled even before info.el is loaded.

> Anyways, I need a way to have this "*Compile-Log*" suppressed or buried.

Yes, I think we should change bytecomp.el so that those warnings get
output via `message' when we're not byte-compiling a whole file.

Actually, no, it's been there for quite a while.

Actually, while the general problem is old, its appearance in your case
is indeed due to a recent change in advice.el which I think was a bug.
I've installed a patch on trunk which should fix the problem.
Please confirm,

Fixed.  The bug can be closed.

Some book-keeping info,

    1. *Compile-Log* no longer comes to the fore.
    2. It contains a sole warning 

        ,----
        | elisp/bbdb-2.35/lisp/bbdb-com.elc:Warning: Use `with-current-buffer' rather
        |     than save-excursion+set-buffer
        `----

    3. The warning pertaining to defadvice has disappeared.

Thanks, done.

Until someone changes bytecomp.el to use `message' when compiling
a single function, you'll either have to live it or fix it on
BBDB's side.
BTW, you might like to upgrade to bbdb-3.
