This adds a new URL parser, which aims to be compliant with the URL
specification (https://url.spec.whatwg.org/). It also contains a
rudimentary data URL parser.
Since I introduced this functionality there has been a steady stream of
people building with `ALL_THE_DEBUG_MACROS` and trying to boot the
system, and immediately hitting this assert. I have no idea why people
try to build with all the debugging enabled, but I'm tired of seeing the
bug reports about asserts we know are going to happen at this point.
So I'm hiding this value under the new ENABLE_ALL_DEBUG_FACILITIES flag
instead. This is only set by CI, and hopefully no-one will try to build
with this thing (It's documented as not recommended).
Fixes: #7527
Previously ByteBuffer::grow() behaved like Vector<T>::resize().
However the function name was somewhat ambiguous - and so this patch
updates ByteBuffer to behave more like Vector<T> by replacing grow()
with resize() and adding an ensure_capacity() method.
This also lets the user change the buffer's capacity without affecting
the size which was not previously possible.
Additionally this patch makes the capacity() method public (again).
Since this program is setuid-root, it should be as simple as possible.
To that end, remove `/etc/plsusers` and use filesystem permissions to
achieve the same thing. `/bin/pls` is now only executable by `root` or
members of the `wheel` group.
Also remove all the logic that went to great lengths to `unveil()` a
minimal set of filesystem paths that may be used for the command.
The complexity-to-benefit ratio did not seem justified, and I think
we're better off keeping this simple.
Finally, remove pledge promises the moment they are no longer needed.
These dbgln's caused excessive load in the WebServer process,
accounting for ~67% of the processing time when serving a webpage
with a bunch of resources like serenityos.org/happy/2nd/.
With the increased volume of PRs being opened and merged lately,
multiple people have complained that the IRC is absolutely flooded with
SerenityBot posts. Remove the IRC notifications from the CI scripts, and
the Meta script that handles parsing the github actions context into
an IRC message.
It seems like overly-specific classes were written for no good reason.
Instead of making each adapter to have its own unique FramebufferDevice
class, let's generalize everything to keep implementation more
consistent.
This reverts commit 5018b3b4b7.
Let's help our future selves by making sure we don't introduce a bug
because of duplicating a network interface name or related bug to this
topic. Therefore, we can have multiple e1000 devices in the system now.
Some folks on discord said adding another e1000 network adapter made it
so we don't have networking on the system anymore.
To fix this, we will use other unsupported PCI device instead.
This allows a developer to easily dump a InlineLinkedList in the
debugger without having to manually running the list.
I needed this for a recent bug investigation in the Kernel.
This also optionally generates a test suite from the WebAssembly
testsuite, which can be enabled via passing `INCLUDE_WASM_SPEC_TESTS`
to cmake, which will generate test-wasm-compatible tests and the
required fixtures.
The generated directories are excluded from git since there's no point
in committing them.
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.
Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.
We also check that there were no parser errors when parsing the .cpp
files.
This is similar to the LibJS test data that resides in
/home/anon/js-tests.
It's more convenient than storing the test programs as raw strings
in the code.
As the parser now flattens out the instructions and inserts synthetic
nesting/structured instructions where needed, we can treat the whole
thing as a simple parsed bytecode stream.
This currently knows how to execute the following instructions:
- unreachable
- nop
- local.get
- local.set
- {i,f}{32,64}.const
- block
- loop
- if/else
- branch / branch_if
- i32_add
- i32_and/or/xor
- i32_ne
This also extends the 'wasm' utility to optionally execute the first
function in the module with optionally user-supplied arguments.
This had very bad interactions with ccache, often leading to rebuilds
with 100% cache misses, etc. Ali says it wasn't that big of a speedup
in the end anyway, so let's not bother with it.
We can always bring it back in the future if it seems like a good idea.
As we removed the support of VBE modesetting that was done by GRUB early
on boot, we need to determine if we can modeset the resolution with our
drivers, and if not, we should enable text mode and ensure that
SystemServer knows about it too.
Also, SystemServer should first check if there's a framebuffer device
node, which is an indication that text mode was not even if it was
requested. Then, if it doesn't find it, it should check what boot_mode
argument the user specified (in case it's self-test). This way if we
try to use bochs-display device (which is not VGA compatible) and
request a text mode, it will not honor the request and will continue
with graphical mode.
Also try to print critical messages with mininum memory allocations
possible.
In LibVT, We make the implementation flexible for kernel-specific
methods that are implemented in ConsoleImpl class.
