Allowing an environment variable to enable/disable the build for clangd
and other toolchains will improve the developer-experience than
reconfiguring and building the toolchain manually.
Now you will have to call the command as following
$ CLANG_ENABLE_CLANGD=ON Toolchain/BuildClang.sh
Static analysis is great, but these workflows have not worked in a long
time, and no one was looking at the results. Our PVS Studio license and
our Sonar Cloud token have expired. Remove the workflows (at least for
now) so we don't waste CI runners and cache space. If someone is
motivated to revive these, they can revert this commit.
Turns out clangd supports code formatting using the clang-format
engine. Because we also document another code formatter to install,
when users use both extensions VSCode will ask to choose one or the
other. Therefore, let's just choose clangd for code formatting since
it is needed anyways for code comprehension.
Explain a bit about what pkg is and what it isn't, and clarify that
while Serenity kinda-sorta has the beginnings of a "package manager",
it's not exactly like a typical Linux package manager with binary
software.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
This patch fixes `nix develop` commands not using proper paths, uses
the serenity root directory as an assumption for all commands and
adds variants of nix commands to use a custom entry point, for example
a shell.
If PulseAudio is available, the Qt6 audio plugin will never be used. So
let's remove it from the build.
Note that on macOS, the Qt6 audio plugin will be used if the Qt chrome
is enabled. Otherwise, Audio Unit will be used for the AppKit chrome.
This is the only instance of `*OS's` in the repo that does not use `s`
after the apostrophe.
Generally, the saxon genitive for singular nouns is always written as
`'s` even if they end in `s`.
`-serial mon:stdio` passes through all kinds of key combinations,
`-serial stdio` doesn't. This probably isn't something that we want
while running tests or CI, so switch to the non-passing variant.
aarch64 actually failed to run due to this, since it already had
`-serial stdio` in its arguments, causing a conflict. This is why that
entry is now gone entirely.
`-nographic` additionally reconfigures the Terminal, which clears the
previous scrollback and (ocasionally) breaks line wrapping. This is
probably not something that we want, so only ask for the redirection
behavior.
Unless a new toolchain update has been merged, users should not need to
rebuild their toolchain. Yet, the first thing they see in the build
documentation is to run `Meta/serenity.sh rebuild-toolchain`, which
might incorrectly lead them to use it whenever they encounter an error.
This is a waste of time and causes frustration.
Move any mentions of this option to `Troubleshooting.md` and add a note
to `BuildInstructions.md` about the toolchain build being a one-time
endeavor.
Add another dev shell to `Toolchain/flake.nix` called `ladybird.nix`
that pulls in the dependencies for building Ladybird.
Also update the documentation to mention building with a flake.
Let users save their nix develop derivation in a profile by ignoring
this specific folder. It encourages the following workflow:
```
nix develop Toolchain/ --profile Toolchain/nix-profiles/dev
```
Which stops the dev enviornment being collected in the nix store. Later
devs can come back and do:
```
nix develop Toolchain/nix-profiles/dev
```
To continue where they left off, without having to download everything
from nixpkgs again.
Add a nix flake to `Toolchain/` that wraps the existing nix derivation
`Toolchain/serenity.nix`. This also comes with a lockfile making the nix
developer enviornment setup more reproducible.
We also update the documentation for "other builds" to mention the
flake.
The proper syntax for defining user-defined literals does not require a
space between the `operator""` token and the operator name:
> error: identifier 'sv' preceded by whitespace in a literal operator
> declaration is deprecated
This is a minimal set of changes to allow `serenity.sh build riscv64` to
successfully generate the build environment and start building. This
includes some, but not all, assembly stubs that will be needed later on;
they are currently empty.
The following changes take effect:
1. Annotate FixedStringBuffer => `FixedStringBuffer` in many places.
2. Remove non-existing helpers for FixedStringBuffers. I added them
previously but even then they were removed in a following fixup so these
references were never valid. Therefore let's just put a vague reference
to the fact that we have some helpers for this class in the Kernel, and
let people to figure out quickly by themselves for this topic.
3. Put a sentence to explain that FixedStringBuffer objects are not only
being used in syscall handling code, but also for storing actual data in
both the Thread and Process classes as well.
In distributions with newer versions of OpenSSL, when you run
Meta/serenity.sh rebuild-toolchain you'll get curl: (35)
error:0A000152:SSL routines::unsafe legacy renegotiation
disabled. This is because OpenSSL was compiled with legacy
renegotiation disabled by default. I've added instructions
to Documentation/BuildInstructions.md to solve this issue.
The documentation for building Ladybird gives a list of packages to
install under openSUSE, but is missing the Qt6 Multimedia development
package, qt6-multimedia-devel.
Include it.
This includes a few new options to the .clang-format configuration file
to A) adhere to option changes within clang-format 16 (namely the option
AlignTrailingComments), and B) enforce existing style guide rules with
new clang-format rules.
The build instructions include build-essential,
which installs gcc and g++.
However, build-essential's currently stable version (v12.9) depends on
a version of g++ < 12, thus, Ladybird doesn't build.
Doing this removes the qt6-svg dependency and allows our rasterizer to
be used for these little icons (and happens to be a fair bit smaller
than the old SVGs).
This creates (and installs upon WebContent startup) a platform plugin to
play audio data.
On Serenity, we use AudioServer to play audio over IPC. Unfortunately,
AudioServer is currently coupled with Serenity's audio devices, and thus
cannot be used in Ladybird on Lagom. Instead, we use a Qt audio device
to play the audio, which requires the Qt multimedia package.
While we use Qt to play the audio, note that we can still use LibAudio
to decode the audio data and retrieve samples - we simply send Qt the
raw PCM signals.
There have been multiple reports of Xcode 14.0 (based on upstream LLVM
14) segfaulting when compiling `LibCore/Process.cpp`. Let's require
Xcode 14.3, which is a known good version based on LLVM 15.
Note that Xcode 14.3 requires macOS Ventura, so users of Monterey or
older are expected to get Homebrew Clang instead.
Homebrew Clang 13 also suffers from the same crash. Although I have not
tested on Linux, the backtrace points to the middle-end, so x86_64 is
also likely to be affected. LLVM 14 was released 14 months ago, so it's
not an unreasonable requirement.
This is a mostly straight-forward rebase of our patches on top of
13.1.0. The spec files needed a change, as GCC no longer supports STABS
debug information, but we were building GCC with support for it.
Highlights of this release include static `operator()`, The Equality
Operator You Are Looking For and extended `constexpr` support.
By this point of time, we already have x86-64 support and have removed
i686 support too.
Since we are not the only OS project to remove 32-bit support entirely
and 64-bit computing is the norm for modern personal computers, there's
no need to explain this as it's obvious "why we are 64-bit only".
This is an implementation that tries to follow the spec as closely as
possible, and works with Qemu's Intel HDA and some bare metal HDA
controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide
a lot of detailed information that could help us getting this to work
on more bare metal controllers as well :^)
Output format is limited to `i16` samples for now.
"image" was an alias for "qemu-image".
I want to add an `image` userland utility, which clashes with that
shortname.
So remove the existing "image" target. It was just an alias for
"qemu-image".
If you use serenity.sh to build, nothing changes. This only affects you
if you run ninja manually -- you now have to say `ninja qemu-image` to
build the disk image.
Add some prose to the introduction of Lagom about how we use it. Also,
move the section on including Lagom in other projects above the fuzzer
documentation.
Remove the explicit cmake commands from the Fuzzer documentation, as the
script should be the source of truth.
This filesystem is based on the code of the long-lived TmpFS. It differs
from that filesystem in one keypoint - its root inode doesn't have a
sticky bit on it.
Therefore, we mount it on /dev, to ensure only root can modify files on
that directory. In addition to that, /tmp is mounted directly in the
SystemServer main (start) code, so it's no longer specified in the fstab
file. We ensure that /tmp has a sticky bit and has the value 0777 for
root directory permissions, which is certainly a special case when using
RAM-backed (and in general other) filesystems.
Because of these 2 changes, it's no longer needed to maintain the TmpFS
filesystem, hence it's removed (renamed to RAMFS), because the RAMFS
represents the purpose of this filesystem in a much better way - it
relies on being backed by RAM "storage", and therefore it's easy to
conclude it's temporary and volatile, so its content is gone on either
system shutdown or unmounting of the filesystem.
Instead of explaining custom build directories first and then following
that up with a an explainer that Meta/serenity.sh is the easiest way to
get the browser up and running to try it out was not very ergonmic.
Also reorganize some of the per-distro documentation to put the compiler
requirements front and center.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
The setting of scan code set sequence is removed, as it's buggy and
could lead the controller to fail immediately when doing self-test
afterwards. We will restore it when we understand how to do so safely.
Allow the user to determine a preferred detection path with a new kernel
command line argument. The defualt option is to check i8042 presence
with an ACPI check and if necessary - an "aggressive" test to determine
i8042 existence in the system.
Also, keep the i8042 controller pointer on the stack, so don't assign
m_i8042_controller member pointer if it does not exist.
The biggest difference is that -m32 is no longer important, and in fact
breaks every 64-bit setup.
Also, defining ENABLE_UNICODE_DATA, ENABLE_COMPILETIME_FORMAT_CHECK, and
__SSE__ makes some code "visible" in the #ifdef sense, which improves
syntax highlighting.
/etc/mtab is identical to /proc/self/mounts, but it does not exist under
many circumstances, e.g. chroot'ed or in WSL. The fact that many
userspace programs rely on this file existing and the user needing to
create symlinks manually has been a long-standing issue (there's pretty
old forum posts on Debian and Arch Linux forums about it), but it's not
fixed upstream. This short mention should save people some time.
In the fresh and minimal installations dev package are often
stripped. This commit will install the libssl dev packages
required in `Utilities/cmcurl/CMakeLists.txt:608`.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Changing the naming conventions one-by-one was tedious and error-prone.
A settings file is likely to be more forward compatible than a
screenshot. The settings file was made by repeating the manual steps
provided in the documentation, and exporting the file in CLion.
The two major changes noticeable on the SerenityOS codebase are:
- Much improved support for const placement, clang-format-14 ignored
our east-const configuration in various places
- Different formatting for requires clauses, now breaking them onto
their own line, which helps with readability a bit
Current versions of CLion also ship LLVM 15, so the built-in formatting
now matches CI formatting again :^)
As Evil stated in the Discord, WSL users must install the DLL
libraries with their QEMU Installation or else they will receive
obscure errors about the syntax of the Meta/run.sh file as shown in
SerenityOS#14033.
YouCompleteMe is a plugin for Vim which provides code-completion
functionality. This change adds a configuration file which makes
YouCompleteMe aware of which compile flags to use with clangd.
