Resources embedded by the embed_resource() function will now also expose
a SECTION_start and SECTION_size symbol so the embedded resource can be found
by an application without having to parse its own ELF image which is not
something applications can currently do from userspace.

* Add SERENITY_ARCH option to CMake for selecting the target toolchain
* Port all build scripts but continue to use i686
* Update GitHub Actions cache to include BuildIt.sh

It doesn't seem right to not have the website in version control.
Also this way people can make changes to it. :^)

The partitioning code was very outdated, and required a full refactor.
The new subsystem removes duplicated code and uses more AK containers.
The most important change is that all implementations of the
PartitionTable class conform to one interface, which made it possible
to remove unnecessary code in the EBRPartitionTable class.
Finding partitions is now done in the StorageManagement singleton,
instead of doing so in init.cpp.
Also, now we don't try to find partitions on demand - the kernel will
try to detect if a StorageDevice is partitioned, and if so, will check
what is the partition table, which could be MBR, GUID or EBR.
Then, it will create DiskPartitionMetadata object for each partition
that is available in the partition table. This object will be used
by the partition enumeration code to create a DiskPartition with the
correct minor number.

The DevFS along with DevPtsFS give a complete solution for populating
device nodes in /dev. The main purpose of DevFS is to eliminate the
need of device nodes generation when building the system.
Later on, DevFS will assist with exposing disk partition nodes.

This is a script similar to the clang-format one to ensure prettier
formatting of most JavaScript files.
|
|
This should speed up pre-commit a bit as only files that are staged will
be processed, and clang-format and shellcheck are only invoked once, not
for every file. When no arguments are given (e.g. on CI), it still uses
'git ls-files'.
|
|
This needs '-o' to work correctly. Also update the shebang to bash in
some scripts as shellcheck was complaining about pipefail not being a
POSIX shell thing otherwise.

I just picked three apps at random: Browser, TextEditor and Help.
This should make it a bit more visible that we have a working desktop.

This commit gets rid of ELF::Loader entirely since its very ambiguous
purpose was actually to load executables for the kernel, and that is
now handled by the kernel itself.
This patch includes some drive-by cleanup in LibDebug and CrashDaemon
enabled by the fact that we no longer need to keep the ref-counted
ELF::Loader around.
|

We now configure the gcc spec files to use a different crt files for
static & PIE binaries.
This relieves us from the need to explicitly specify the desired crt0
file in cmake scripts.

Problem:
- The first lint check that fails results in all subsequent checks not
being run.
Solution:
- Run all the lint checks aggregating the number of failures.
- Return a non-0 exit code if any have failed.
|
|
Problem:
- It is possible for a new test file to be added to the `AK/Tests`
directory without being added to the corresponding
`CMakeLists.txt`. This results in the tests not being run.
Solution:
- As part of CI linting, verify that all the `AK/Tests/Test*.cpp`
files are mentioned in the `CMakeLists.txt`.
|
|
Problem:
- These utility functions are only used in `AK`, but are being defined
in the top-level. This clutters the top-level.
Solution:
- Move the utility functions to `Meta/CMake/utils.cmake` and include
where needed.
- Also, move `all_the_debug_macros.cmake` into `Meta/CMake` directory
to consolidate the location of `*.cmake` script files.
|
|
Problem:
- Modifying CXXFLAGS directly is an old CMake style.
- The giant and ever-growing list of `*_DEBUG` macros clutters the
top-level CMakeLists.txt.
Solution:
- Use the more current `add_compile_definitions` function.
- Sort all the debug options so that they are easy to view.
- Move the `*_DEBUG` macros to their own file which can be included
directly.

After all the work of determining the correct name for clang-format-10,
we forgot to actually use it. How silly!

New serenity_app() targets can be defined which allows application
icons to be emedded directly into the executable. The embedded
icons will then be used when creating an icon for that file in
LibGUI.
|
|
Problem:
- `(void)` simply casts the expression to void. This is understood to
indicate that it is ignored, but this is really a compiler trick to
get the compiler to not generate a warning.
Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.
Note:
- Functions taking a `(void)` argument list have also been changed to
`()` because this is not needed and shows up in the same grep
command.

This patch replaces the UI-from-JSON mechanism with a more
human-friendly DSL.
The current implementation simply converts the GML into a JSON object
that can be consumed by GUI::Widget::load_from_json(). The parser is
not very helpful if you make a mistake.
The language offers a very simple way to instantiate any registered
Core::Object class by simply saying @ClassName
@GUI::Label {
text: "Hello friends!"
tooltip: ":^)"
}
Layouts are Core::Objects and can be assigned to the "layout" property:
@GUI::Widget {
layout: @GUI::VerticalBoxLayout {
spacing: 2
margins: [8, 8, 8, 8]
}
}
And finally, child objects are simply nested within their parent:
@GUI::Widget {
layout: @GUI::HorizontalBoxLayout {
}
@GUI::Button {
text: "OK"
}
@GUI::Button {
text: "Cancel"
}
}
This feels a *lot* more pleasant to write than the JSON we had. The fact
that no new code was being written with the JSON mechanism was pretty
telling, so let's approach this with developer convenience in mind. :^)

This allows us to get rid of some ByteBuffer::wrap() usage.

Shell-backgrounding seems to be deadlocking at times, until that's
fixed, let's not take 5 hours to fail the build.

There are cases where Lagom will build with GCC but not Clang.
This often goes unnoticed for a while as we don't often build with
Clang.
However, this is now important to test in CI because of the
OSS-Fuzz integration.
Note that this only tests the build, it does not run any tests.
Note that it also only builds LagomCore, Lagom and the fuzzers.
It does not build the other programs that use Lagom.
|
|
We added OSS-Fuzz integration in #4154, but documentation about it
is spread across several pull requests, IRC, and issues. Let's collect
the important bits in the ReadMe.

This commit is a mix of several commits, squashed into one because the
commits before 'Move regex to own Library and fix all the broken stuff'
were not fixable in any elegant way.
The commits are listed below for "historical" purposes:
- AK: Add options/flags and Errors for regular expressions
Flags can be provided for any possible flavour by adding a new scoped enum.
Handling of flags is done by templated Options class and the overloaded
'|' and '&' operators.
- AK: Add Lexer for regular expressions
The lexer parses the input and extracts tokens needed to parse a regular
expression.
- AK: Add regex Parser and PosixExtendedParser
This patchset adds a abstract parser class that can be derived to implement
different parsers. A parser produces bytecode to be executed within the
regex matcher.
- AK: Add regex matcher
This patchset adds an regex matcher based on the principles of the T-REX VM.
The bytecode pruduced by the respective Parser is put into the matcher and
the VM will recursively execute the bytecode according to the available OpCodes.
Possible improvement: the recursion could be replaced by multi threading capabilities.
To match a Regular expression, e.g. for the Posix standard regular expression matcher
use the following API:
```
Pattern<PosixExtendedParser> pattern("^.*$");
auto result = pattern.match("Well, hello friends!\nHello World!"); // Match whole needle
EXPECT(result.count == 1);
EXPECT(result.matches.at(0).view.starts_with("Well"));
EXPECT(result.matches.at(0).view.end() == "!");
result = pattern.match("Well, hello friends!\nHello World!", PosixFlags::Multiline); // Match line by line
EXPECT(result.count == 2);
EXPECT(result.matches.at(0).view == "Well, hello friends!");
EXPECT(result.matches.at(1).view == "Hello World!");
EXPECT(pattern.has_match("Well,....")); // Just check if match without a result, which saves some resources.
```
- AK: Rework regex to work with opcodes objects
This patchsets reworks the matcher to work on a more structured base.
For that an abstract OpCode class and derived classes for the specific
OpCodes have been added. The respective opcode logic is contained in
each respective execute() method.
- AK: Add benchmark for regex
- AK: Some optimization in regex for runtime and memory
- LibRegex: Move regex to own Library and fix all the broken stuff
Now regex works again and grep utility is also in place for testing.
This commit also fixes the use of regex.h in C by making `regex_t`
an opaque (-ish) type, which makes its behaviour consistent between
C and C++ compilers.
Previously, <regex.h> would've blown C compilers up, and even if it
didn't, would've caused a leak in C code, and not in C++ code (due to
the existence of `OwnPtr` inside the struct).
To make this whole ordeal easier to deal with (for now), this pulls the
definitions of `reg*()` into LibRegex.
pros:
- The circular dependency between LibC and LibRegex is broken
- Eaiser to test (without accidentally pulling in the host's libc!)
cons:
- Using any of the regex.h functions will require the user to link -lregex
- The symbols will be missing from libc, which will be a big surprise
down the line (especially with shared libs).

Fixes #4145.
|

This was broken with the JS::Parser::Error position changes, but I don't
actually see a reason to do anything with the parser errors here, so
let's remove it and consider simply not crashing a success. :^)

It finds the problem fixed in 69518bd178ebfaa but nothing else.

What a silly mistake. How did I manage to do that?

This avoids "useless" join/part notifications.
