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.
The internal reuse of FixedMemoryStream makes this straightforward.
There alread is one user of the new API, demonstrating the need for this
change beyond what I said out to use it for :^)
Since it will become a stream in a little bit, it should behave like all
non-trivial stream classes, who are not primarily intended to have
shared ownership to make closing behavior more predictable. Across all
uses of MappedFile, there is only one use case of shared mapped files in
LibVideo, which now uses the thin SharedMappedFile wrapper.
Previously, the same file would be counted more than once if its
containing directory was visited multiple times, or there were
multiple hard links pointing to it.
We now keep track of every visited inode to ensure that files aren't
evaluated multiple times. This matches the behavior of `du` on FreeBSD
and Linux.
When updating /usr/Ports/AvailablePorts.md, the file or even the entire
/usr/Ports directory might not exist.
To cope with this, we should be able to create it ourselves. To ensure
we are able to do this, we should unveil both /usr and /usr/Ports.
