DateTime can now be parsed from a string. Implements the same formatters
as strptime: https://linux.die.net/man/3/strptime (Well, some of them at
least).
IODeviceStreamReader isn't pulling its weight.
It's essentially a subset of InputFileStream with only one user
(WavLoader).
This refactors WavLoader to use InputFileStream instead.
When LibC/shadow.cpp parses shadow entries in getspent, it sets the
spwd member value to disabled (-1) if the value is empty. When
Core::Account::sync calls getspent to generate a new shadow file, it
would recieve the -1 values and write them in the shadow file. This
would cause the /etc/shadow file to be cluttered with disabled values
after any password change.
This patch checks if the spwd member value is disabled, and prints the
appropriate value to the shadow file.
Right now Socket::send() assumes that it can send everything in one
go. However, send() is allowed to do partial writes and while that
can't happen at the moment there's nothing that says this can't
happen in the future (like in the next commit).
This patch adds 13 new detectable file formats, which are as follows in
alphabetical order:
.blend, .isz, ext* filesystem, Lua bytecode, Matroska container, NES
ROM, .pdf, qcow image, .rtf, WebAssembly bytecode, Windows 3.1X/95
compressed archive and raw zlib stream
Some are a tad esoteric, but the more file types we detect, the more
useful this utility becomes! :^)
This functionality, while neat, isn't really something you need enabled
all the time. Let's make it opt-in instead. Pass MakeInspectable::Yes
to the Core::EventLoop constructor if you want your program to become
inspectable.
If a line was larger than 1024 bytes or the file ended without a
newline character, can_read_line would return false.
IODevice::can_read_line() now reads until a newline is found or
EOF is reached.
fixes#5907
Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
Second batch of detectable formats, this time with verious offsets, as
enabled by the previous commit.
This adds tar, and the three signature variants for iso-9660 image
files.
Previously accept() would copy the listener socket's cloexec and
non-blocking flag. With that fixed however TCPServer and LocalServer
now leak file descriptors into child processes and are blocking.
This changes Core::File::open() to specify O_CLOEXEC by default
so that we don't leak file descriptors into child processes. The
new behavior can be overriden by specifying OpenMode::KeepOnExec.
Core::EventLoop now makes an outbound connection to InspectorServer
instead of listening for incoming connections on a /tmp/rpc/PID socket.
This has many benefits, for example:
- We no longer keep an open listening socket in most applications
- We stop leaking socket files in /tmp/rpc
- We can tighten the pledges in many programs (patch coming)
With the new InodeWatcher API, the old style of creating a watcher per
inode will no longer work. Therefore the FileWatcher API has been
updated to support multiple watches, and its users have also been
refactored to the new style. At the moment, all operations done on a
(Blocking)FileWatcher return Result objects, however, this may be
changed in the future if it becomes too obnoxious. :^)

The LOCKER() macro appears to have been added to LibThread as a
userspace analog to the previous LOCKER() macro that existed in
the kernel. The kernel version used the macro to inject __FILE__ and
__LINE__ number into the lock acquisition for debugging. However
AK::SourceLocation was used to remove the need for the macro. So
the kernel version no longer exists. The LOCKER() in LibThread doesn't
appear to actually need to be a macro, using the type directly works
fine, and arguably is more readable as it removes an unnecessary
level of indirection.
This attempts to guess the mime-type from a given set of bytes from the
start of a file. It only supports a few well-defined patterns for now,
but it's a start!
This also moves Widget::load_from_json into Core::Object as a virtual
function in order to allow loading non-widget objects in GML (e.g.
BoxLayout).

The user's GID is already available via gid(), and it's not "extra", so
don't include it in extra_gids() again. Also rename the internally used
function from get_gids() to get_extra_gids() to make its purpose more
clear.
