This commit replaces the 5 fuzzers that previously tested LibTextCodec
with a single fuzzer. We now rely on the fuzzer to generate the
encoding and separate it from the encoded data with a magic separator.
This increases the overall coverage of LibTextCodec and eliminates the
possibility of the same error being generated by multiple fuzzers.
We can now just unveil the /dev/beep device node, as well as to restrict
the utility functionality for rpath, wpath & stdio related syscalls only
because we don't actually need anything else.
There's no need to have separate syscall for this kind of functionality,
as we can just have a device node in /dev, called "beep", that allows
writing tone generation packets to emulate the same behavior.
In addition to that, we remove LibC sysbeep function, as this function
was never being used by any C program nor it was standardized in any
way.
Instead, we move the userspace implementation to LibCore.
Previously these handlers duplicated code and used formats that
were different from the one Error.prototype.stack uses.
Now they use the same Error::stack_string function, which accepts
a new parameter for compacting stack traces with repeating frames.
If we invoke the exit native function from within the exit builtin, the
native call will then invoke global destructors. This ultimately ends up
deleting the JS::NativeFunction that defines the exit builtin, thus we
try to delete the AK::Function held inside the NativeFunction while that
AK::Function is executing. This is explicitly forbidden by AK::Function.
Instead, simply set a flag to exit the REPL after the builtin executes.
This patch brings a service to handle image decompression. With it comes
security enhancement due to the process boundary. Indeed, consequences
of a potential attack is reduced as only the decoder will crash without
perturbing the WebContent process.
It also allows us to display pages containing images that we claim to
support but still make us crash, like for not-finished-yet decoders.
As an example, we can now load https://jpegxl.info/jxl-art.html without
crashing the WebContent process.
This makes the parser more resilient to invalid IMAP messages.
Usages of `Optional` have also been removed where the empty case is
equivalent to an empty object.
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
The POSIX specification for `find` says that: "Each path operand shall
be evaluated unaltered as it was provided, including all trailing
<slash> characters". This also matches the behavior of `find` on
FreeBSD and Linux.
These functions all have a very common case that can be dealt with a
very simple inline check, often avoiding the need to call an out-of-line
function. This patch moves the common case to inline functions in a new
ValueInlines.h header (necessary due to header dependency issues..)
8% speed-up on the entire Kraken benchmark :^)
As the newly created function has been also applied to printing the
number of matched file lines, file names will now also be colored
with the `--count` option set. :^)
Previously we had two somewhat duplicated methods: one just for handling
stdin with the standard C API, and the other one used for everything
else with our Core::File class. By using always Core::File, the code
should be now a little bit cleaner.
Additionally, grep will now use the standard input when it finds a '-'
argument (previously it tried to open a file with that name.)
We currently only return primary time zones, i.e. time zones that are
not a Link. LibJS will require knowledge of Link entries, and whether
each entry is or is not a Link.
The "dependency" lines really belong to the main port entry, it doesn't
make sense logically to represent them separately and handling them
together will also allow easier dependency management later on. This
commit greatly simplifies the port database parsing to facilitate this,
and removes the -d option from the command line. Instead, ports are
listed with their dependencies, if they have any.
The program now terminates with an error if the command passed to
`-exec` is not terminated with a semicolon.
This commit also ensures that the argument containing the terminating
semicolon must be 1 byte long. Previously, any argument whose first
byte was a semicolon was treated as a valid terminator.
This behaves identically to the `-exec` option but prompts the user
for confirmation before executing the specified command.
A command is executed if a line beginning with 'y' or 'Y' is entered
by the user. This matches the behavior of `find` on Linux and FreeBSD
when using the POSIX locale.
