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 removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
The server cannot use these values anywhere, because this method always
sets 'prompt = ShouldPrompt::No'. This saves a bunch of roundtrips for
all clients that use FSAS to read abritrary files.
Previously FSAC displayed some but not all errors and always
rejected directories and devices. This has led most apps to ignore
response errors in open/save actions or show redundant messages.
Now FSAC displays all errors including fd failures and has the ability
to silence messages for directories, devices and ENOENT, which some
apps handle differently. Silenced directory and device errors now
return files on success.
A request's access mode is now stored in RequestData to format more
accurate error messages from the user's perspective.
Resolved promises don't require callback propagation so they're voided
`handle_prompt_end` is calling `is_device` and `is_directory` on the
path chosen by the user. However, this path is not necessarily unveiled.
Meaning that it the both functions results in an illegal operation.
This is a regression introduced with the usage of LibFileSystem in
1d24f394. This patch, revert the behavior at its previous state, i.e.
calling both functions with the fd provided by the FSAS.
Concerned functions are:
- try_request_file_read_only_approved_deprecated
- try_request_file_deprecated
- try_open_file_deprecated
- try_save_file_deprecated
It also allows some simplifications in the implementation of the client.
This patch reimplements the now deprecated try_open_file(),
try_request_file() and try_request_file_read_only_approved() functions,
with the difference that the new ones return a FSAC::File object
(currently a wrapper with a Core::Stream and a filename) instead of a
Core::File.
Implemented in a similar manner to 6dd716adf2.
The new result returned just a file stream, which wasn't sufficient
enough for most applications because it didn't provide a filename.
This patch will make a new File object that has both a file stream and
a filename.
These functions return the deprecated `Core::File` class, so let's mark
it as such to avoid possible confusion between future non try_*
functions which will use Core::Stream family classes and to possibly
grab someone's attention. :^)
This patch also updates corresponding functions from
`LibFileSystemAccessServerClient`.
From the FileSystemAccessClient point of view, it only makes the server
take `Core::Stream::OpenMode` instead of `Core::OpenMode`. So, `enum`
conversions only happen within deprecated functions and not in the new
`Core::Stream` friendly API.
On the server side, it just removes two usages of `Core::File::open()`.
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 :^)
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
This commit does three things atomically:
- switch over Core::Account+SystemServer+LoginServer to sid based socket
names.
- change socket names with %uid to %sid.
- add/update necessary pledges and unveils.
Userland: Switch over servers to sid based sockets
Userland: Properly pledge and unveil for sid based sockets
This patch allows to insert "%uid" in `IPC_CLIENT_CONNECTION`
declaration and in SystemServer's ini files. This pattern is replaced
then replaced by the UID of the owner of the service. It opens a path
for seamlessly managed, per-user portal.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
These functions were changed to synchronous in #13870 but
the async_ versions were still being called. This led to
frequent crashes when loading local files in Browser.
Before this patch, when you called FileSystemAccessServer::Client::try_*
twice, the second call used the same variable to store the promise. This
"race condition" is now solved using a HashMap, to store multiple
parallel requests.
Since all users of the old API are now removed, this commit removes all
the methods that returned raw file descriptors, in favor of returning
`ErrorOr<NonnullRefPtr<Core::File>`.
The current implementation is a bit of a hack since we also want to keep
around the previous variants for now, but will be cleaned up later once
all applications have been ported to the new API.
This change unfortunately cannot be atomically made without a single
commit changing everything.
Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.
The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
C_OBJECT and will generate a static try_create factory function for
the ServerConnection subclass. The subclass is now responsible for
passing the socket constructed in this function to its
ServerConnection base; the socket is passed as the first argument to
the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
any other arguments.
- The functionality regarding taking over sockets from SystemServer has
been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
implementation of this functionality hasn't been deleted due to my
intention of removing this class in the near future and to reduce
noise on this (already quite noisy) PR.
There can be cases when one wants to open a file not just for reading
but also for writing. It was already possible to have a custom open mode
for request_file, now it is also possible through the open/save dialogs.
FileSystemAccessServer requires all paths to be absolute, and will
just crash if this is not the case. Instead of expecting the user to
always provide an absolute path, the client just checks to see if
the path provided was absolute, and if not makes a request with the
absolute path instead.
This commit adds a new request to the FileSystemAccessServer
endpoint, allowing the clients to get read-only access to a file
without getting a Dialog-box prompting the user for access.
This is only meant to be used in cases where the user has asked
specifically to open a file through the command-line arguments.
In those cases, I believe it makes sense for the read-only access
to be implicit. Always prompting the user gets a bit annoying,
especially if you just quickly want to open a file through the CLI.
The new request name has been made extremely specific to make sure
that it's only used when appropriate.
This transitions from synchronous IPC calls to asynchronous IPC calls
provided through a synchronous interface in LibFileSystemAccessClient
which allows the parent Application to stay responsive.
It achieves this with Promise which is pumping the Application event
loop while waiting for the Dialog to respond with the user's action.
LibFileSystemAccessClient provides a lazy singleton which also ensures
that FileSystemAccessServer is running in the event of a crash.
This also transitions TextEditor into using LibFileSystemAccessClient.
