Added input hook into console widget to allow input to be captured and
sent to the external JS console via IPC.
Output from the external JS console is fed into the console widget
via handle_js_console_output().
Because registering and unregistering interrupt handlers triggers
calls to virtual functions, we can't do this in the constructor
and destructor.
Fixes#5539
You can now view the individual samples in a profile one by one with
the new "Samples" view. The "old" main view moves into a "Call Tree"
tab (but it remains the default view.)
When you select a sample in the samples view, we show you the full
symbolicated backtrace in a separate view on the right hand side. :^)
This way you don't have to look at all the library names if you don't
want to. Since we're pretty good about namespacing our things, the
library names are slightly redundant information.
This is already set in the root CMakeLists.txt as well as here for Clang
(-Wno-user-defined-literals), but was forgotten for GCC which made an
Lagom-only build (cmake ../Meta/Lagom [...]) fail.
The Locator now keeps a cache of the declared symbol in a document.
The language client updates that cache whenever it gets an update from
the language server about declared symbols.
This allows searching for symbol declarations in the Locator, in
addition to file names.
Closes#5478
Having TextRange which is empty doesn't make any sense. So it confuses
the functions that rely on having valid range, and causes them to do
no action.
Fixes#5341
The sample Wizard subclasses WizardDialog and demonstrates a front and
back cover, as well as extracting user input from a Wizard page to
display in the interface which spawned the Wizard.
This patch provides the basic components needed for developers to create
consistent wizard interface experiences in their applications.
`WizardDialog` provides the dialog frame for the wizard, handling navigation
and presentation.
`AbstractWizardPage`s form the base class of Wizard pages, which are
pushed onto the `WizardDialog` page stack via `WizardDialog::push_page`.
`CoverWizardPage` and `WizardPage` are provided to ease the creation of
Wizard interfaces consistent with the Serenity visual language.
We don't need to flush the on-disk inode struct multiple times while
writing out its block list. Just mark the in-memory Inode as having
dirty metadata and the SyncTask will flush it eventually.
Since the inode is the logical owner of its block list, let's move the
code that computes the block list there, and also stop hogging the FS
lock while we compute the block list, as there is no need for it.
There are two locks in the Ext2FS implementation:
* The FS lock (Ext2FS::m_lock)
This governs access to the superblock, block group descriptors,
and the block & inode bitmap blocks. It's held while allocating
or freeing blocks/inodes.
* The inode lock (Ext2FSInode::m_lock)
This governs access to the inode metadata, including the block
list, and to the content data as well. It's held while doing
basically anything with the inode.
Once an on-disk block/inode is allocated, it logically belongs
to the in-memory Inode object, so there's no need for the FS lock
to be taken while manipulating them, the inode lock is all you need.
This dramatically reduces the impact of disk I/O on path resolution
and various other things that look at individual inodes.
Since these filesystems operate on an underlying file descriptor
and rely on its offset for correctness, let's use the FS lock to
serialize these operations.
This also means that FS subclasses can rely on block-level read/write
operations being atomic.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
