f378352051 tests: Mark tests with AddressSanitizer-detected leaks
Various tests have leaks where it isn't clear whether the data is
intentionally not freed, or leaked due to a bug. If we mark these
tests as TODO, we can skip them under AddressSanitizer and get the
rest to pass, giving us a baseline from which to avoid regressions.

ee3216b31b tests: Iterate the GMainContext directly rather than using a GMainLoop
This speeds up the `cancellable` test a little by stopping waiting for
the threads to start up as soon as they have started, rather than after
an arbitrary timeout.

5b12608157 tests: Fix intermittent failure in GCancellableSource test
It seems that allowing the GCancellable to be finalised in either the
main thread or the worker thread sometimes leads to crashes when running
on CI.

I cannot reproduce these crashes locally, and various analyses with
memcheck, drd and helgrind have failed to give any clues.

Fix this for this particular test case by deferring destruction of the
`GCancellable` instances until after the worker thread has joined.
That’s OK because this test is specifically checking a race between
`g_cancellable_cancel()` and disposal of a `GCancellableSource`.

The underlying bug remains unfixed, though, and I can only hope that we
eventually find a reliable way of reproducing it so it can be analysed
and fixed.

9f27f49e34 tests: Speed up the cancellable test
The test added for #1841 spawned 100000 threads. That was fine on a
desktop machine, but on a heavily loaded CI machine, it could result in
large (and unpredictable) slowdowns, resulting in the test taking over
120s in about 1 in 5 runs, and hence failing that CI pipeline due to a
timeout. When passing normally on CI, the test would take around 90s.

Here’s a histogram of time per iteration on a failing (timed out) test
run. Each iteration is one thread spawn:

  Iteration duration (µs) | Frequency
  ------------------------+----------
                     ≤100 |     0
                  100–200 | 30257
                  200–400 | 13696
                  400–800 |  1046
                 800–1000 |   123
                1000–2000 |   583
                2000–4000 |  3779
                4000–8000 |  4972
               8000–10000 |  1027
              10000–20000 |  2610
              20000–40000 |   650
              40000–80000 |    86
             80000–100000 |    10
            100000–200000 |     2
                  >200000 |     0

There’s no actual need for the test to spawn 100000 threads, so rewrite
it to reuse a single thread, and pass new data to that thread.

Reverting the original commit (e4a690f5dd) reproduces the failure on
100 out of 100 test runs with this commit applied, so the test still
works.

The test now takes 3s, rather than 11s, to run on my computer, and has
passed when run with `meson test --repeat 1000 cancellable`.

e4a690f5dd gcancellable: Fix minor race between GCancellable and GCancellableSource
There’s a minor race condition between cancellation of a `GCancellable`,
and disposal/finalisation of a `GCancellableSource` in another thread.

Thread A                               Thread B
 g_cancellable_cancel(C)
 →cancellable_source_cancelled(C, S)
                                       g_source_unref(S)
                                       cancellable_source_dispose(S)
 →→g_source_ref(S)
 →→# S is invalid at this point; crash

Thankfully, the `GCancellable` sets `cancelled_running` while it’s
emitting the `cancelled` signal, so if `cancellable_source_dispose()` is
called while that’s high, we know that the thread which is doing the
cancellation has already started (or is committed to starting) calling
`cancellable_source_cancelled()`.

Fix the race by resurrecting the `GCancellableSource` in
`cancellable_source_dispose()`, and signalling this using
`GCancellableSource.resurrected_during_cancellation`. Check for that
flag in `cancellable_source_cancelled()` and ignore cancellation if it’s
set.

The modifications to `resurrected_during_cancellation` and the
cancellable source’s refcount have to be done with `cancellable_mutex`
held so that they are seen atomically by each thread. This should not
affect performance too much, as it only happens during cancellation or
disposal of a `GCancellableSource`.

3894335dc6 tests: Don't "timeout tests" by default
Those tests seem to regularly fail because a timeout (which we're
measuring outside the function that times out) is too long, which can
happen when the system is busy.

Don't run those tests unless "thorough" tests are requested. This
disables those tests by default.

e13c646465 gcancellable: add back lost NULL check in g_cancellable_cancel()
Commit f975858e86 removed the NULL check in g_cancellable_cancel() by
accident which makes it crash when called with NULL.

Add the check back and add a test so this doesn't happen again.

17bb9d542c gio/tests/cancellable: fix to still work when running slowly
The test was assuming that all cancelled ops would finish within a
certain amount of time, but this often failed under valgrind. Instead,
just run the loop until all of the ops have actually finished.
