Bug 30730

This test starts up one of the example connection managers with g_spawn_async() and does stuff with it. It's hard to tell from the debug output, but the test may have some sort of race condition resulting from that?

I seem to be able to hit it consistently, so if it's a race condition then it may be influenced by the environment. Hints on further debugging are appreciated.

I can't see an actual failure in that debug output: could it have happened earlier? On failure, there should be a line that says "ERROR", "WARNING" or "CRITICAL".

If you're logging the output to a file, you'll need both stdout and stderr (e.g. by running it with "2>&1 | tee output.log").

If you run the test under gdb, like this, you might be able to get a better idea why it's failing:

abs_top_builddir=/home/graaff/playground/test/telepathy-glib-0.12.0 \
libtool --mode=execute gdb tests/dbus/test-example-no-protocols

If it fails, you'll get normal output, followed by a gdb prompt; use the command "bt full" to find out where you are and why, and "quit" to quit.

It might also be interesting to add

    g_message ("in wait_for_name_owner_cb");

to the beginning of wait_for_name_owner_cb() in tests/dbus/example-no-protocols.c, and similar for early_cm_exited().

Running the test manually gets me an ERROR:

tp-glib:ERROR:base-connection-manager.c:255:tp_base_connection_manager_constructor: assertion failed: (cls->protocol_params != NULL)

gdb isn't helpful n this case because it ends up in a timeout.

That assertion failure can't happen in version 0.12, and indeed line 255 isn't an assertion any more! I think I know what's happening here now, though: for some reason the example CM that's being run is using your installed version of telepathy-glib, but it requires the newer version 0.12.

Could you please tell me what output these commands produce, when you're in the top-level telepathy-glib source directory and have the same environment you've been using to compile it:

    echo ${LD_LIBRARY_PATH+not_set}

    ./libtool --mode=execute ldd \
    examples/cm/no-protocols/telepathy-example-no-protocols

    make -C examples/cm/no-protocols \
    -W main.c \
    -n telepathy-example-no-protocols

Also, what telepathy-glib version(s) do you have installed system-wide, and where are they? (/usr/lib, /usr/local/lib, /opt/whatever, etc.)

These git patches might fix it:

Could you try out this snapshot version, please? I believe it will probably fix this bug.

Thanks!

I have telepathy-glib-0.10.7 installed in /usr/lib64 (which is the default /usr/lib on a stock Gentoo amd64 system).

Woohoo!

Thanks!

Excellent. In that case, this is already fixed in git, and will be fixed in the 0.12.2 and 0.13.3 releases. Thanks for your help!
