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.
So far we've gotten away with using GCC 11 for Lagom and to compile the
toolchain, but via #15795 we discovered a compiler bug that has been
fixed in the latest version but would error the build with CI's GCC 11.
Time for an upgrade :^)
We already use ubuntu-22.04 images in most places, so this is pretty
straightforward. The only exception is Idan's self-hosted runner, which
uses Ubuntu Focal. LibJS should build fine with GCC 11, still.
