Now that we use SSE in some inline assembly, it needs to be at least 16.
However, _Alignof(max_align_t) can be just 8. file: [ab0ba34911] check-in: [c80075f6e4] user: js, branch: trunk, size: 1415 [annotate] [blame] [check-ins using] [diff]

This removes functionality which will be restored later. file: [5a8629e6a6] check-in: [43c80a7593] user: js, branch: trunk, size: 1442 [annotate] [blame] [check-ins using] [diff]

This didn't work without problems on all OSes. Since ofatalkcfg is no
longer there, there is no reason to keep this for now. In the future, if
there is a more generic replacement for ofatalkcfg, this can just be
reverted. file: [b557faae7b] check-in: [550bd1b7bb] user: js, branch: trunk, size: 1487 [annotate] [blame] [check-ins using] [diff]

It seems that neither Windows nor macOS support DDP sockets, but only
the layers on top, while neither Linux nor NetBSD support the layers on
top, but only provide DDP.

It seems that DDP is not meant to be used directly, while Linux and
NetBSD only provide the minimum to use netatalk, which is DDP. ObjFW
would need to use the layers on top on Windows and macOS and implement
those layers itself on Linux and NetBSD. This also means that no code
would be shared between Linux / NetBSD and Windows / macOS, as it's
impossible to have one implementation that works for everything. At this
point, the effort required doesn't make sense. file: [46516d773c] check-in: [0b4f713964] user: js, branch: trunk, size: 1299 [annotate] [blame] [check-ins using] [diff]

Windows 10 supports UNIX sockets since Insider Preview Build 17063, but
only SOCK_STREAM. file: [a0cd235af2] check-in: [d5373ff70f] user: js, branch: unix-sockets, size: 1254 [annotate] [blame] [check-ins using] [diff]

When arc4random() is unavailable, either random() or rand() is used and
both need to be seeded. If of_random() is a macro, it needs to be
(re)seeded every time, as it's unknown whether it has already been
seeded. As it is seeded with gettimeofday() due to the lack of a better
initial seed, this means every call returns the first state for the
current time, which is very predictable. random() and rand() are both
not cryptographic, but this should at least make it a little bit better
now. file: [4530c4317b] check-in: [c1fe4b2b77] user: js, branch: trunk, size: 1336 [annotate] [blame] [check-ins using] [diff]

This does *NOT* provide cryptographically secure randomness! file: [0dc3c9abbb] check-in: [a2a06d372a] user: js, branch: trunk, size: 1221 [annotate] [blame] [check-ins using] [diff]

Note: There is still some weirdness in the compiler. Instead of
m68k-amigaos-gcc, you need to use m68k-amigaos-g++ as OBJC, as otherwise
exceptions don't work.

Before running the tests, you need to run "stack 8192". file: [558f07b729] check-in: [49cb6ada5f] user: js, branch: trunk, size: 1173 [annotate] [blame] [check-ins using] [diff]

Only OpenBSD's pledge() is supported so far. file: [095ccff6f0] check-in: [40cf53506a] user: js, branch: trunk, size: 1034 [annotate] [blame] [check-ins using] [diff]

This is only useful for size-constrained systems and changes the
behavior as follows:

* Case-insensitive comparisons only work as expected for ASCII
characters. This means that while a and A compare equal, ä and Ä do
not.

* -[OFMutableString {upper,lower}] and
-[OFString {upper,lower}caseString] only work on ASCII characters;
all other characters are left as they are. This means that the upper
version of a is A, but the upper version of ä is still ä (and vice
versa for lower). file: [c0f587b66b] check-in: [b7b33247d6] user: js, branch: trunk, size: 1012 [annotate] [blame] [check-ins using] [diff]

Having one file per implementation reduces the #ifdef hell and makes it
much more readable. file: [f68c946c0e] check-in: [7115c55ef0] user: js, branch: trunk, size: 951 [annotate] [blame] [check-ins using] [diff]

This removes the port registry that existed for the Wii and instead
tries binding to random ports in a loop until it succeeds or errno is
not EADDRINUSE. This is done for the Wii and Nintendo 3DS now.

This also includes several other socket-related cleanups. file: [84b0a50859] check-in: [12b8a7552e] user: js, branch: trunk, size: 928 [annotate] [blame] [check-ins using] [diff]

In case (v)asprintf was missing, this was exported instead of only being
used internally, potentially causing problems when linking against
another library which also detected libc is missing it. file: [793b73003c] check-in: [ddbbd50e56] user: js, branch: trunk, size: 908 [annotate] [blame] [check-ins using] [diff]

If it's unavailable, it's defined to __attribute__((noreturn)).

Unfortunately, it cannot be used for ObjC methods, as noreturn is part
of the return type while __attribute__((noreturn)) needs to be at the
end for an ObjC method. To make matters worse, even GCC versions that
accept noreturn don't allow it for an ObjC method. Thus, the only thing
that can be done is to always use __attribute__((noreturn)) for ObjC
methods using the OF_METHOD_NORETURN define. file: [b0cd6ea182] check-in: [bac91ccede] user: js, branch: trunk, size: 932 [annotate] [blame] [check-ins using] [diff]

If threads.h exists, the thread_local from there is used. If it doesn't,
but _Thread_local exists, it's defined to that. As a last fallback, it
is defined to __thread. file: [41bed793cb] check-in: [c701e89b83] user: js, branch: trunk, size: 905 [annotate] [blame] [check-ins using] [diff]

This is required as OFKernelEventObserver uses struct sockaddr_in as an
instance variable in case there is no pipe(). file: [aa4090a098] check-in: [4de1f2a67a] user: js, branch: trunk, size: 765 [annotate] [blame] [check-ins using] [diff]

When the compiler supports C11, _Alignof(max_align_t) is used; otherwise
the __BIGGEST_ALIGNMENT__ define is tried with a fallback to 16. file: [449e8f592b] check-in: [fdfb2be253] user: js, branch: trunk, size: 716 [annotate] [blame] [check-ins using] [diff]

Currently, no methods returning structs are supported, see the comment

This way, it is theoretically possible to compile ObjFW with one
compiler and then use it with another. file: [2392df0876] check-in: [2edae50b86] user: js, branch: trunk, size: 450 [annotate] [blame] [check-ins using] [diff]

Currently, the properties test for nonatomic fails. This is a bug in
the new GNU runtime. file: [5535a2e37e] check-in: [6f4eb004a3] user: js, branch: trunk, size: 531 [annotate] [blame] [check-ins using] [diff]
