bug#1186: 23.0.60; Abort trap when loading dbus in tty

bug#1186: 23.0.60; Abort trap when loading dbus in tty

[Magnus Henoch]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

emacs -Q -nw
M-x load-library RET dbus RET

At this point, Emacs aborts.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.60/etc/DEBUG for instructions.

Subject: 23.0.60; Abort trap when loading dbus in tty
Date: Thu, 16 Oct 2008 23:23:20 +0200
Message-ID: <87y70op73r.fsf@freemail.hu>

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

emacs -Q -nw
M-x load-library RET dbus RET

At this point, Emacs aborts.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.60/etc/DEBUG for instructions.

I can't reproduce this.

Could you recompile Emacs without optimization, using 

  CFLAGS="-g" ./configure && make

and generate another backtrace?

Thanks.

I couldn't reproduce it also (running Ubuntu 8.10). Could you, please,
add the following option to the built:

  make MYCPPFLAGS='-DDBUS_DEBUG -Wall'

By this, debug messages are printed to your terminal, which might be
useful.

> Thanks.

Best regards, Michael.

With more debugging and less optimization I get:

So, from frame 1, I see that the immediate cause of the crash is that an
error was thrown while Emacs was waiting for output.  This happens only
when xd_initialize is called with :system as an argument; the system bus
is apparently not correctly configured on my system - the dbus library
finds the socket, sends a Hello message, but never gets any answer, as
seen in the s variable of socket 4.

And when I turn off the system bus and try again, the same thing
happens, but with another message:

#4  0x01986158 in xd_initialize (bus=30504729) at /media/e/src/emacs/src/dbusbind.c:688
        s = "Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory", '\0' <repeats 937 times>, "\360"

I don't understand why this doesn't happen when I run Emacs in X...

Thank you for the backtrace, it makes the picture clear. Fsignal must
not be called when reading events in the main loop. But xd_initialize does.

Could you, please, check the appended patch? It ought to prevent Fsignal
calls in this case.

Best regards, Michael.
