ObjFW  History of tests/OFKernelEventObserverTests.m of f6cc2092af2a9dd2

ObjFW's style changed over the years, but the tests were never adjusted
to it. file: [f4ab45b387] check-in: [14f1e22d79] user: js, branch: trunk, size: 5130 [annotate] [blame] [check-ins using] [diff]

OFAutoreleasePools have long been discouraged in favor of the runtime's
autorelease pools. file: [b7d7784260] check-in: [09be825f88] user: js, branch: trunk, size: 5220 [annotate] [blame] [check-ins using] [diff]

This prevents forgetting to add an import to ObjFW.h, as the tests would
then not compile. file: [a86e902d78] check-in: [dc0c6c34ab] user: js, branch: trunk, size: 5236 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [a75e0308f8] check-in: [2f4e0df8be] user: js, branch: trunk, size: 5336 [annotate] [blame] [check-ins using] [diff]

This makes them not run out of resources on Nintendo 3DS. file: [a33e059e26] check-in: [5e0bfb59b4] user: js, branch: trunk, size: 5343 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [f2b6e225cb] check-in: [4af49a13c3] user: js, branch: trunk, size: 5468 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [26a483d9d8] check-in: [44f45c2e35] user: js, branch: trunk, size: 5467 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [09cd1941db] check-in: [cec0f072f8] user: js, branch: 0.8, size: 5294 [annotate] [blame] [check-ins using] [diff]

Now that we can require GCC >= 4.6, we no longer need to have a category
on OFObject that adds the optional protocol to it. file: [87b1a72a6f] check-in: [ba62f00fac] user: js, branch: trunk, size: 5328 [annotate] [blame] [check-ins using] [diff]

This was necessary because select(), poll() and kevent() on FreeBSD and
OS X would sometimes return 0 events, even if there are some, and
sometimes return the correct number of events that were pending, meaning
the number of events returned is unreliable. To make things worse,
whether it returns 0 or the number of events that were pending is
completely non-deterministic on both FreeBSD and OS X (running the same
tests multiple times in a row would make it sometimes work and sometimes
fail).

In order to prevent code from depending on the return value of
-[observeForTimeInterval:] (which would depend on select(), poll() and
kevent() returning the correct number), OFKernelObserver no longer
returns whether there were pending events. It is expected that
-[observe] or -[observeForTimeInterval:] is just called in a loop as
long as events should be handled.

The tests have been changed as well to reflect this. What they do now is
set a deadline and call -[observeForTimeInterval:] with a small timeout
in a loop until the deadline is reached or all events have been handled.

Note: DragonFlyBSD has not been tested, but will most likely behave like
FreeBSD and OS X. file: [8dbc611e84] check-in: [220513a3f5] user: js, branch: trunk, size: 5326 [annotate] [blame] [check-ins using] [diff]
