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.
The `-maxdepth` option limits the number of levels `find` will descend
into the file system for each given starting point.
The `-mindepth` option causes commands not to be evaluated until the
specified depth is reached.
Previously, we used `on_load_finish` to determine when the text test
was completed. This method did not allow testing of async functions
because there was no way to indicate that the runner should wait for
the async call to end.
This change introduces a function in the `internals` object that is
intended to be called when the text test execution is completed. The
text test runner will now ignore `on_load_finish` which means a test
will timeout if this new function is never called.
`test(f)` function in `include.js` has been modified to automatically
terminate a test once `load` event is fired on `window`.
new `asyncTest(f)` function has been introduces. `f` receives function
that will terminate a test as a first argument.
Every test is expected to call either `test()` or `asyncTest()` to
complete. If not, it will remain hanging until a timeout occurs.
Each ref test now links to its reference page with a link tag, in the
same format as WPT:
`<link rel="match" href="reference-page.html" />`
The reference pages have all been moved into a separate `reference/` dir
so that we can just treat every file in `ref/` as a test. There's no
filter to only look at .html files, because we also have a .svg file in
there, and there may be other formats we want to use too. But it's not
too hard to add one if we need it.
If SO_TIMESTAMP is unsupported, we won't be able to determine
kernelspace-to-userspace latency. But other than that, things should
still build and work.
(It's a separate question of what "kernelspace-to-userspace latency"
even means on a microkernel system, where the network card drivers, the
network stack, and ntpquery(1) are all running as userspace programs.)
Also, don't fail completely if settting receive timeout fails.
This works by adding source start/end offset to every bytecode
instruction. In the future we can make this more efficient by keeping
a map of bytecode ranges to source ranges in the Executable instead,
but let's just get traces working first.

These return true if the last modification time, last access time or
creation time of a file is greater than the given reference file.
If the `-L` option is in use and the given reference file is a
symbolic link then the timestamp of the file pointed to by the
symbolic link will be used.
The argument supplied to the `-size` option may now be one of the
following suffixes:
* b: 512-byte blocks. This is the default unit if no suffix is used.
* c: bytes
* w: two-byte words
* k: kibibytes (1024 bytes)
* M: mebibytes (1024 kibibytes)
* G: gibibytes (1024 mebibytes)
Sizes are rounded to the specified unit before comparison. The unit
suffixes are case-sensitive.
Just like on Linux, we can easily print the process creation time. The
format of a printed time is either "hour:minute" if the process started
today, or "short_month_name:day_of_the_month" (for example, "Aug26").
The name "variables" is a bit awkward and what the directory entries are
really about is kernel configuration so let's make it clear with the new
name.
