supercomputer7 c3c905aa6c Kernel: Removing hardcoded offsets from Memory Manager
Now the kernel page directory and the page tables are located at a
safe address, to prevent from paging data colliding with garbage.

Andreas Kling 39fcd92210 Kernel: Remove debug spam about dump_backtrace() calling itself
This was too noisy and important-sounding, when it doesn't really
matter that much. It's not the end of the world if symbolication fails
for one reason or another.

Andreas Kling 8a024a3305 LibGUI: Rename GEventLoop.{cpp,h} => GWindowServerConnection
The GEventLoop class is long gone, and the only class in these files is
GWindowServerConnection, so let's update the file names. :^)

Andreas Kling 69883bea6f LibHTML: Update the removed node's siblings in TreeNode::remove_child()
Oops, we forgot to update the node's siblings' sibling pointers when
removing a node from the tree.

Thanks to Owlinated for pointing this out! :^)

rhin123 96c1e36ed3 TextEditor: Added redo functionality & proper stack manipulation
Added redo functionality & added m_undo_stack_index that moves back &
forth on the stack depending on the undo's & redo's.

Andreas Kling 306cd0d840 Base: Add a local copy of bettermotherfuckingwebsite.com for testing 2019-11-07 21:40:04 +01:00
Andreas Kling 0355146af9 LibHTML: Ignore case in <!DOCTYPE> tags :^) 2019-11-07 21:39:15 +01:00
Andreas Kling 71f249fd2c LibHTML: Draw box borders even if we don't have a border-color
In those cases we should fall back to currentColor, which is hackishly
implemented by falling back to "color" for now.

Andreas Kling ee2cafc15c LibHTML: Fix the default style for <hr> elements
This was broken because we don't expand CSS shorthand properties (yet.)

Andreas Kling 56764a2db8 LibHTML: Don't swallow '}' as part of CSS property values 2019-11-07 21:20:18 +01:00
Andreas Kling 397acde846 LibHTML: Turn "&mdash;" into "-" in the parser for now
Ultimately we should deal with all the various HTML entitites.

Andreas Kling d6c0d32b63 HackStudio: Make the project file list a little narrower by default 2019-11-07 21:06:31 +01:00
Andreas Kling 870be9d71e AK: Add Vector::take(index)
This removes an item from the vector and returns it.

Andreas Kling d6f9349f15 IRCClient: Escape HTML entities in nicknames, too, just in case 2019-11-07 18:09:52 +01:00
Andreas Kling 68e23bca3f AK: Delete operator!() and operator bool() from the Nonnull pointers
Since NonnullRefPtr and NonnullOwnPtr cannot be null, it is pointless
to convert them to a bool, since it would always be true.

This patch makes it an error to null-check one of these pointers.

Andreas Kling b88ff97537 LibHTML: Make the CSS parser return RefPtr's
It should be possible for the CSS parser to fail, and we'll know it
failed if it returns nullptr. Returning RefPtr's makes it actually
possible to return nullptr. :^)

Andreas Kling 6a8695e759 AK: Add Vector::prepend(T&&) 2019-11-07 10:35:13 +01:00
Andreas Kling a377e8d3f5 LibHTML+IRCClient: Add an escape_html_entities() helper
This simple helper escapes '<', '>' and '&' so they can be used in HTML
text without interfering with the parser.

Use this in IRCClient to prevent incoming messages from messing with
the DOM :^)

Andreas Kling 1133acabb2 Meta: Move "Notes on WSL" to a separate file in Documentation/
Since this is not relevant to the majority of people, let's move it
out of the way.

Andreas Kling 2c693094d9 Kernel: If a process is interrupted during usleep(), return -EINTR 2019-11-06 21:01:44 +01:00
Andreas Kling ac2cc7d78f LibHTML: Make parse_html_document() return a RefPtr
Parsing might not always succeed, so let's have a way to signal errors.
2019-11-06 20:54:50 +01:00
Andreas Kling f60c46ceb7 IRCClient: Use parse_html_fragment() to add messages to the HtmlView
HTML fragment strings are so much nicer to work with than raw DOM APIs.
This makes it feel like we're using innerHTML :^)

Andreas Kling 794f2d5645 LibHTML: Rename parse_html() => parse_html_document() 2019-11-06 20:52:18 +01:00
Andreas Kling f5cf8d4ad8 Revert "LibHTML: Rename parse_html() => parse_html_document()"
This reverts commit f6439789db.
Oops, I committed unrelated changes here, let me clean that up..

Andreas Kling f6439789db LibHTML: Rename parse_html() => parse_html_document() 2019-11-06 20:31:56 +01:00
Andreas Kling 635717ed0f LibHTML: Add parse_html_fragment()
This function parses a partial DOM and returns it wrapped in a document
fragment node (DocumentFragment.)

There are now two entrances into the HTML parser, one for parsing full
documents, and one for parsing fragments. Internally the both wrap the
same parsing function.
2019-11-06 20:30:39 +01:00
Andreas Kling f404a1dc16 LibHTML: Add DocumentFragment
Right now this is just a simple ParentNode subclass with its node type
being DOCUMENT_FRAGMENT_NODE.
2019-11-06 20:27:53 +01:00
Andreas Kling 26493a3039 LibHTML: Add TreeNode::remove_child()
This removes a child from the tree and returns it to the caller.
It optionally (but by default) calls removed_from(parent) on the child.

Andreas Kling 9a5e065229 AK: Always rebuild unit tests if AK headers change
This is a hack to avoid failing AK unit tests because it didn't even
try to rebuild.

Andreas Kling 2f16e31afc Kernel: A running process should keep its TTY alive
It's not safe to use a raw pointer for Process::m_tty. A pseudoterminal
pair will disappear when file descriptors are closed, and we'd end up
looking dangly. Just use a RefPtr.
2019-11-06 16:52:54 +01:00
Andreas Kling 083c5f8b89 Kernel: Rework Process::Priority into ThreadPriority
Scheduling priority is now set at the thread level instead of at the
process level.

This is a step towards allowing processes to set different priorities
for threads. There's no userspace API for that yet, since only the main
thread's priority is affected by sched_setparam().
2019-11-06 16:30:06 +01:00
Andreas Kling e33bbdb6ba AK: Remove unused AK::not_implemented()
Whatever this was supposed to be, it was ironically... not implemented.

Andreas Kling 14dc323f4d Kernel: Sort the C++ objects in the Makefile 2019-11-06 13:45:21 +01:00
Andreas Kling 49635e62fa LibELF: Move AK/ELF/ into Libraries/LibELF/
Let's arrange things like this instead. It didn't feel right for all of
the ELF handling code to live in AK.

Andreas Kling 31beff8afb Kernel: Remove unnecessary init_ksyms() function 2019-11-06 13:36:37 +01:00
Andreas Kling 4f4d4670fe Kernel: Don't instantiate and throw away ProcFS + DevPtsFS on boot
Oops, we were creating these and then throwing them away. They will
get instantiated a bit later, when we bring up the mounts in /etc/fstab
from userspace.
2019-11-06 13:21:44 +01:00
Andreas Kling 9a4b117f48 Kernel: Simplify kernel entry points slightly
It was silly to push the address of the stack pointer when we can also
just change the callee argument to be a value type.
2019-11-06 13:15:55 +01:00
Andreas Kling 349d2ec1c2 Kernel: Link with libgcc
This allows us to get rid of all the custom 64-bit division helpers.
I wanted to do this ages ago but couldn't get it working. Turns out it
was unstable due to libgcc using the regular ABI and the kernel being
built with -mregparm=3.

Now that we build the kernel with regular calls, we can just link with
libgcc and get this stuff for free. :^)
2019-11-06 13:07:07 +01:00
Andreas Kling 1c6f8d3cbd Kernel: Don't build with -mregparm=3
It was really confusing to have different calling conventions in kernel
and userspace. Also this has prevented us from linking with libgcc.
2019-11-06 13:04:47 +01:00
Andreas Kling 01b21e5e05 Kernel: Use KParams::has() instead of !KParams::get().is_null()
Also rename a local variable to be consistent with what it represents.
2019-11-06 11:47:04 +01:00
Andreas Kling 9e570d0d6d Kernel+SystemServer: Get rid of two virtual consoles
Having four virtual (text) consoles by default seems really overkill
for a system that can't even switch to them anyway (yet!)
2019-11-06 11:41:50 +01:00
Andreas Kling 2ad0ec325a AK: Get rid of TStyle (output styling helper for LogStream)
This didn't end up getting used, so let's get rid of it.
2019-11-06 11:37:03 +01:00
Andreas Kling 1c8f017730 Kernel: Remove unused SynthFS filesystem
This used to be the base class of ProcFS and DevPtsFS but not anymore.
2019-11-06 11:36:24 +01:00
Andreas Kling f3f0b08d43 LibHTML: Build some foundation for text selection
Add LayoutPosition and LayoutRange classes. The layout tree root node
now has a selection() LayoutRange. It's essentially a start and end
LayoutPosition.

A LayoutPosition is a LayoutNode, and an optional index into that node.
The index is only relevant for text nodes, where it's the character
index into the rendered text.

HtmlView now updates the selection start/end of the LayoutDocument when
clicking and dragging with the left mouse button.

We don't paint the selection yet, and there's no way to copy what's
selected. It only exists as a LayoutRange.

Andreas Kling 2755184e11 HackStudio: Update the "remove current editor" action enabled state
This action should not be enabled when there is only one editor open,
since you are not allowed to be editor-less.
2019-11-05 21:08:17 +01:00
Andreas Kling cb627a3ada HackStudio: Allow removing the current editor with Alt+Shift+E
Note that you are not allowed to remove the very last editor.

These keybinds are all temporary while I figure out what the right ones
should be. I'm not exactly sure how, but it'll reveal itself. :^)
2019-11-05 21:02:31 +01:00
Andreas Kling 538d5f82c1 HackStudio: Allow switching between editors with Ctrl+E / Ctrl+Shift+E 2019-11-05 20:56:36 +01:00
Andreas Kling f844715106 HackStudio: Allow adding more editors by pressing Ctrl+Alt+E
We also now start out with a single editor, instead of two. :^)

Andreas Kling d3558b6137 LibCore+LibGUI: Allow inserting a CObject/GWidget before another
When adding a widget to a parent, you don't always want to append it to
the set of existing children, but instead insert it before one of them.

This patch makes that possible by adding CObject::insert_child_before()
which also produces a ChildAdded event with an additional before_child
pointer. This pointer is then used by GWidget to make sure that any
layout present maintains the correct order. (Without doing that, newly
added children would still be appended into the layout order, despite
having a different widget sibling order.)
