While trying to make the tests pass, I accidentally some unrelated and semi-related fixes.
Created attachment 95534 [details] [review] textchan-group: improve debug
Created attachment 95535 [details] [review] Use concrete dbus-glib parameterized types, not G_TYPE_VALUE_ARRAY dbus_g_value_build_g_variant() doesn't yet understand how to build a tuple from a G_TYPE_VALUE_ARRAY, so my branch to use GDBus for everything will rely on using the full parameterized types.
Created attachment 95536 [details] [review] TpContact: mime_file_written: don't leak the file's path --- Might be a bugfix for master/stable also, I haven't checked. Could someone else? I'm busy shaving this yak.
Created attachment 95537 [details] [review] TpTestsContactsConnection: don't leak list_manager
Created attachment 95538 [details] [review] Ignore allocations in gobject_init_ctor
Created attachment 95539 [details] [review] TpBaseContactList: don't leak groups hash table --- Not tested with any real CMs. Someone probably should before this reaches master, just to be safe.
Created attachment 95540 [details] [review] TpProxy: finish_all_requests: don't leak copied GQueue
Created attachment 95541 [details] [review] account test: don't leak copied strings
Created attachment 95542 [details] [review] TpTestsSimpleChannelDispatcher: don't leak various struct members
Created attachment 95543 [details] [review] cli-group test: don't leak GMainLoop
Created attachment 95544 [details] [review] channel-introspect test: enable debug-logging
Created attachment 95545 [details] [review] tests: extend timeout 10 seconds is too short under valgrind, and this is only really a safety-catch against never terminating.
Created attachment 95546 [details] [review] GDBus can deliver more than one event per main-loop iteration --- The comment + * We shouldn't assert len == 1 above because this happens automatically, + * and when we do a _run_ call, GDBus can give us than one + * event per main loop iteration (dbus-glib went to some lengths + * not to do so). */ should maybe move further up the file; or not. This is the first of the commits that should maybe wait until we merge the GDBus branch.
Created attachment 95547 [details] [review] dbus test: don't re-enter main loop to request/release names GDBus guarantees that it will alternate signalling names appearing and vanishing, and this reentrant usage probably breaks that. It was a terrible idea anyway. --- The commit message is maybe a little misleading. It still re-enters the main loop, but it re-enters in an idle, not in the name ownership change callback, which is less bad. I didn't really feel like rewriting this to use proper calls right now, the diffstat for this branch is terrifying anyway.
Created attachment 95548 [details] [review] invalidated-while-invoking-signals test: move to GTest
Created attachment 95549 [details] [review] invalidated-while-invoking-signals test: extend test coverage Since commit 6f153bca, we didn't wait for on_status_changed() to occur. At some point it ceased to be reached at all, which meant that commit db582a0d added an unbalanced unref for @client in what has now become teardown(). If on_status_changed() was executed, it would unref the client, and then the unref in teardown() would either be a use-after-free or indirectly lead to one. Porting telepathy-glib to GDBus exposed this bug, by making on_status_changed() reachable again. While fixing this I noticed that on_status_changed() is not guaranteed to be the last-unref, so the test does not necessarily even reproduce the original crash situation, which was the proxy being invalidated inside the signal callback. I've addressed that by testing once with the way the test has worked in practice since at least 2012, and once with explicit forced invalidation.
Created attachment 95551 [details] [review] tp_tests_assert_last_unref: add Some tests find this functionality useful. --- I might omit this one if I discover that nothing actually needs it by the time I'm ready to land the GDBus branch.

(In reply to comment #21) > TpTestsContactsConnection: don't leak list_manager This was in fact incorrect: in 0.22, create_channel_managers() returns the ref, leaving list_manager as a borrowed ref to something tracked by the base class. That seems poor style, but is valid. It's possible that this changed between 0.22 and next.
(In reply to comment #6) > TpBaseContactList: don't leak groups hash table In 0.22, this is OK, but redundant: the same function already does a tp_clear_pointer(). Again, perhaps this changed between 0.22 and next.

Again, perhaps this changed between 0.22 and next. It did. It regressed in b91113d2 during early 'next' development. Fixed in git for 0.99.8.

Yes it did, when the base contact list ceased to be a channel manager, turning this weird memory management into a leak. Fixed in git for 0.99.8.
