ObjFW  History of src/OFStreamObserver.h of merge-in:41ddf50

The new file socket.h includes all headers required for sockets on the
used platform, while the file socket_helpers.h defines the BSD API
functions to the platform specific functions if necessary.

This cleans up the classes dealing with sockets a lot and also reduces
code duplication. file: [268952c0f7] check-in: [81d47f4398] user: js, branch: trunk, size: 5771 [annotate] [blame] [check-ins using] [diff]

This is used instead for time intervals now instead of doubles. file: [de0e796056] check-in: [dc31ce3d34] user: js, branch: trunk, size: 6000 [annotate] [blame] [check-ins using] [diff]

Not functional yet due to bugs in the SDK.
Bugs found so far:

* Binding to port 0 fails instead of choosing a free port.
* gethostbyname() does not work for IPs.
* getsockname() is missing.
* struct sockaddr_storage is missing.

I have not decided yet whether I fix those bugs in the SDK (I already
implemented getsockname() and added struct sockaddr_stroage and it seems
to work) or if I work around them in ObjFW. This will mainly depend on
how cooperative the developers of the Wii SDK are. file: [1ad6295688] check-in: [ffb91daffe] user: js, branch: trunk, size: 6235 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [36adc90c29] check-in: [c5ef582958] user: js, branch: trunk, size: 5814 [annotate] [blame] [check-ins using] [diff]

EV_RECEIPT is not available on all systems implementing kqueue. file: [429a39bc00] check-in: [1edb3cb8c7] user: js, branch: trunk, size: 5470 [annotate] [blame] [check-ins using] [diff]

* Make it possible to close a stream before the add/remove queue has
been processed.
* The actual implementations don't need to handle OFStreams now, but
get the file descriptor instead.
* Use an OFMutex instead of @synchronized. file: [b87bb931e4] check-in: [47caef4f8a] user: js, branch: trunk, size: 5276 [annotate] [blame] [check-ins using] [diff]

This makes it impossible for the developer to accidentally create a DoS.
When data has been received after calling -[tryReadLine] and the string
is still incomplete, -[streamIsReadyForReading:] will not be called
anymore until new data has been received, thus preventing spinning in a
loop. file: [aece4ad798] check-in: [535c2d5d9b] user: js, branch: trunk, size: 5199 [annotate] [blame] [check-ins using] [diff]

Not working on win32 yet, it will be ported to it later as it's not that
easy there, since select() can only observe sockets. file: [7b1f8623a5] check-in: [a61ab37726] user: js, branch: trunk, size: 4739 [annotate] [blame] [check-ins using] [diff]

It does not cancel the currently running -[observe] yet when changing
the set of streams to observe. file: [abbf9520ca] check-in: [35aab77af3] user: js, branch: trunk, size: 4106 [annotate] [blame] [check-ins using] [diff]

It also looks at the cache of each stream now and does not block if
there is still data in the cache. file: [572eeb8e96] check-in: [b554732eae] user: js, branch: trunk, size: 3104 [annotate] [blame] [check-ins using] [diff]

We assume now that every object understands retain, release, etc. so
that we can weaken the type from OFObject* to id. This makes it
possible to use different root object classes. file: [943d945622] check-in: [e2b06423e0] user: js, branch: trunk, size: 3020 [annotate] [blame] [check-ins using] [diff]
