When handling child creation in FileSystemModel, the new child should
be inserted such that the children still follow the correct order of
being grouped by directory-and-file and then sorted alphabetically,
instead of just being appended at the end.
Previously, the null state of m_root_path was use to (subtly) mark the
parent of the root. The empty path is always replaced with "." so after
aeee98b there was no "parent of root" node. This lead to the file
manager crashing when opened.
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 following commit will port MIME types to String. Traits<String>
- used in Vector::contains_slow - can't compare String type with char*,
so we need to use StringView instead.
Add the function FileSystemModel::Node::can_delete_or_move which will
cache the result of FileSystem::can_delete_or_move for a node. This
prevents having to make system calls repeatedly to obtain this
information.
Fixes#18399
As the user might want to have interactions with LibGUI while handling
errors, this code should be executed in the original `EventLoop`.
Similarly to what is done with the error-free path.
With the new canceled background actions, some thumbnail generation
callbacks are not executed if the user closes the window with a
FileSystemModel quickly enough. Therefore, we remember which thumbnails
we started to generate and consider the associated promises if we're
looking up a thumbnail. Since the thumbnail generation itself continues
running and the cache is application-global, instead of never displaying
thumbnails for images that were "interrupted" generating thumbnails the
first time, we can now fetch their images immediately and reliably.
This also removes DirIterator::error_string(), since the same strerror()
string will be included when you print the Error itself. Except in `ls`
which is still using fprintf() for now.
This allows FileSystemModel to take an optional list of allowed file
extensions which it will use to filter out all files that don't end
with that file extension.
The file extensions are set via `set_allowed_file_extensions` which has
a coresponding `get_allowed_file_extensions`.
This patch allows returning an `Error` from the `on_complete` callback
in `BackgroundAction`.
It also adds a custom callback to manage errors returned during its
execution.
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 :^)
This adds icons for folder paths ending in ".git". This adds 16x16 and
32x32 versions of a folder with a Git logo for both the closed and open
versions of the folder icon.
When the location currently displayed in FileManager is removed, find
the nearest existing parent path and open it in the window.
Without the fix, the FileManager window remained in the deleted
directory.
Changing the path in 'DirectoryView' object will automatically update
other components in the FileManager (breadcrumb bar, directory tree
view).
This commit fixes FileSystemModel behaviour when the root path of the
model has been deleted.
In this case, the model index resolved for the root path is invalid and
passing it to 'begin_delete_rows' would trigger assertion failure.
Instead of deleting all children rows one by one, we simply invalidate
the whole model.
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
This converts the return value of File::read_link() from String to
ErrorOr<String>.
The rest of the change is to support the potential of an Error being
returned and subsequent release of the value when no Error is returned.
Unfortunately at this stage none of the places affected can utililize
our TRY() macro.
If a thumbnail cannot load it's a good opportunity to print out the
error message.
On top of that, we still want to update m_thumbnail_progress so that
the progress bar doesn't get stuck instead of returning early from
the lambda.
This adds automatic scrolling when dragging items in TreeViews and other
widgets that inherit from AbstractView when the overloaded
accepts_drag() returns true. This is implemented in FileSystemModel to
allow directories and files to be dragged.
When a file deletion event happens, we now iterate over all views of the
FileSystemModel and remove any selection & cursor indices that hold
dangling references do the deleted filesystem node.
This fixes#9602.
