This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.
With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.
This currently allocates in .parse(), but that's better than making the
caller do the exact same before passing us the values.
Note that this is only temporary to aid in conversion, a future commit
will remove this and switch to requiring the users to allocate the
vector instead.
At the moment, this processes the RIFF chunk structure and extracts
the ICCP chunk, so that `icc` can now print ICC profiles embedded
in webp files. (And are image files really more than containers
of icc profiles?)
It doesn't even decode image dimensions yet.
The lossy format is a VP8 video frame. Once we get to that, we
might want to move all the image decoders into a new LibImageDecoders
that depends on both LibGfx and LibVideo. (Other newer image formats
like heic and av1f also use video frames for image data.)
This was called from LibCore and passed raw StringView data that may
not be null terminated, then incorrectly passed those strings to
getenv() and also tried printing them with just the %s format
specifier.
Similar to the return values earlier, a signed value doesn't really make
sense here. Relying on the much more standard `size_t` makes it easier
to use Stream in all contexts.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
`Process::get_name()` and `Process::set_name()` are basically the same
as `get_process_name()` and `set_process_name()`, except making use of
convenient Serenity standard types and returning ErrorOr, instead of
char* and errno shenanigans.
`Process::set_name()` has an optional `SetThreadName` parameter, for
when you also want to set the thread's name to the same thing. That's
true for the two places that use `set_process_name()`.
Besides from a general check if a file's directory has write
permissions, this also checks if the directory has set a sticky bit,
meaning that only file owners and the directory owner can remove or move
files in such directory. It's being used in /tmp for example.
At the moment, there is no immediate advantage compared to just calling
the underlying functions directly, but having a common interface feels
more ergonomic (users don't have to care about how a type serializes)
and maybe we'll find a way to hide the actual implementation from direct
access some time in the future.
The macOS FileWatcher depends on macOS dispatch queues, which run on a
different thread than the Core::EventLoop. This implementation handles
filesystem events on its dispatch queue, then forwards the event back to
the main Core::EventLoop for notifying the FileWatcher owner.
This will be handy for platforms which need to be able to store extra
OS-specific members. For example, macOS needs to store a dispatch queue,
and event stream, etc.
A negative return value doesn't make sense for any of those functions.
The return types were inherited from POSIX, where they also need to have
an indicator for an error (negative values).
InodeWatcherFlags is an enumeration from the Kernel. To avoid using it
outside of Serenity, add a FileWatcherFlags for FileWatcher, much like
we already have FileWatcherEvent::Type.
This is currently being implicitly including by InodeWatcherEvent.h by
way of FileWatcher.h. The former will soon be removed from the latter,
which would otherwise cause a compile error in these files.
