f83263a72b Kernel: Use a raw VM region for sorting ELF symbols instead of a Vector. 
This avoids putting pressure on kmalloc() during backtrace symbolication.
Since we dump backtrace for every process that exits, this is actually a
decent performance improvement for things like GCC that chain a lot of
processes together.

e9b619c4aa JsonParser: Support basic escaped string characters. 
I didn't implement \uXXXX-style escape in this patch. That's a FIXME.

583606a2b1 StringImpl: Fix possible uninitialized access in StringImpl::create(). 
If the provided length is 0, there's no need to dereference the const char*.

dd36f797d5 JsonObject: Let the compiler generate a copy constructor. 
This was only needed while HashMap was noncopyable. :^)

15003245cd JsonArray: Add for_each() helper. 2019-06-24 12:02:31 +02:00
Andreas Kling
2c1c4ab116 AK: Make it possible to move and copy HashMap and HashTable. 
Previously it was only possible to move them, but we should allow copying
as well, since it's gonna be useful for many things.
 2019-06-24 11:57:54 +02:00
Andreas Kling
009b9bfd10 AK: Implement a naive JSON parser. 
This parser assumes that the JSON is well-formed and will choke horribly
on invalid input.

Since we're primarily interested in parsing our own output right now, this
is less of a problem. Longer-term we're gonna need something better. :^)

bad8ab697b NonnullRefPtr: Simplify copy constructors. 2019-06-24 10:23:59 +02:00
Andreas Kling
2dd54f062a AK: Mark some helper things constexpr. 2019-06-24 10:13:28 +02:00
Andreas Kling
bf97b9589d NonnullRefPtr: Some improvements. 
- Delete the default constructor instead of just making it private.
  It's never valid to create an empty NonnullRefPtr.

- Add copy assignment operators. I originally omitted these to force use
  of .copy_ref() at call sites, but the hassle/gain ratio is minuscule.

- Allow calling all the assignment operators in all consumable states.
  This codifies that it's okay to overwrite a moved-from NonnullRefPtr.

7e1cb86da7 LibHTML: Make it possible to build LibHTML on the host. 
- "make" builds the normal Serenity libhtml.a
- "make -f Makefile.host" builds a test program for the host machine.

3ed17b0792 printf: Support %zu (the 'z' is really just ignored.) 2019-06-22 16:30:32 +02:00
Andreas Kling
1277d583ef printf: Oops, '-' is the left padding modifier, not ' '. 
It's kinda funny how I can make a mistake like this in Serenity and then
get so used to it by spending lots of time using this API that I start to
believe that this is how printf() always worked..

a7dc1a7d6b AK: Make StringImpl a bit smaller. 
There's no need for a member char* m_characters if we always store them
in the inline buffer. So with this patch, we now do.
After that, rearrange the members a bit for ideal packing. :^)

8c0ae711d8 Kernel+LibC: Make page fault crashes a bit more readable. 
We'll now try to detect crashes that were due to dereferencing nullptr,
uninitialized malloc() memory, or recently free()'d memory.
It's not perfect but I think it's pretty good. :^)

Also added some color to the most important parts of the crash log,
and added some more modes to /bin/crash for exercising this code.

Fixes #243.

Andreas Kling
92cda74724 AK: Fix leak in JsonValue::operator=(JsonValue&&). 
Amusingly I introduced this leak while explaining that this type of leak is
a common bug, and saying I'm used to looking for it. :^)
 2019-06-18 09:22:19 +02:00
Andreas Kling
4147394dcb AK: Add JsonValue(const char*). 
This should obviously become a string, but if we don't have it, constructing
from a string literal ends up creating a boolean value.

Andreas Kling
ee347effac AK: Use a single StringBuilder throughout JSON serialization. 2019-06-17 21:36:54 +02:00
Andreas Kling
04a8fc9bd7 AK: Add some classes for JSON encoding. 
This patch adds JsonValue, JsonObject and JsonArray. You can use them to
build up a JsonObject and then serialize it to a string via to_string().

This patch only implements encoding, no decoding yet.
 2019-06-17 19:47:35 +02:00
Andreas Kling
01d1aee922 AK: Make RetainPtr and Retained more friendly towards const pointers. 
Also add operator T&'s to Retained since it's nice to be able to pass them
to a function that takes a T&.

bfaa74f076 AK/Tests: Test Queue<String> with large number of elements. 2019-06-15 10:39:19 +02:00
Andreas Kling
c699d9d79d AK: Add a simple Queue<T> class. 
The underlying data structure is a singly-linked list of Vector<T>.
We never shift any of the vector contents around, but we batch the memory
allocations into 1000-element segments.
 2019-06-15 10:35:35 +02:00
Andreas Kling
9443957c14 PaintBrush: Speed up the bucket tool with smarter use of Vector. 
Put together a pretty well-performing queue using a Vector and an offset.
By using the new Vector::shift_left(int) instead of Vector::take_first()
we can avoid shifting the vector contents every time and instead only
do it every so often.

Maybe this could be generalized into a separate class, I'm not sure if it's
the best algorithm though, it's just what I came up with right now. :^)

Andreas Kling
b7cca76ca2 AK: Add an extremely primitive unit test for String. 
This builds for the host system rather than for Serenity.
We need to improve on it a *lot*, but at least it's a place to start.
 2019-06-14 06:42:21 +02:00
Sergey Bugaev
1a697f70db AK: Add more StringView utilities for making substrings. 
These two allow making a new substring view starting from,
or starting after, an existing substring view.

Also make use of one of them in the kernel.

3e326de8fa AK: Fix nullptr dereference in String::matches(). 
In case cp and mp were never set, we should not try
to use them.
 2019-06-14 06:24:02 +02:00
Sergey Bugaev
e585ed48b0 AK: Fix String::matches() with non-null-terminated StringViews. 
StringView character buffer is not guaranteed to be null-terminated;
in particular it will not be null-terminated when making a substring.
This means it is not correct to check whether we've reached the end
of a StringView by comparing the next character to null; instead, we
need to do an explicit length (or pointer) comparison.

cdb44be703 StringView: Store a StringImpl* rather than a String*. 2019-06-08 23:55:13 +02:00
Andreas Kling
6a51093ab1 AK: Add String::operator==(const char*). 
Without this function, comparing a String to a const char* will instantiate
a temporary String which is obviously not great.

Also add some missing null checks to StringView::operator==(const char*).
 2019-06-08 18:32:09 +02:00
Andreas Kling
de65c960e9 Kernel: Tweak some String&& => const String&. 
String&& is just not very practical. Also return const String& when the
returned string is a member variable. The call site is free to make a copy
if he wants, but otherwise we can avoid the retain count churn.
 2019-06-07 20:58:12 +02:00
Andreas Kling
de9edb0169 StringView: operator==(const char*) needs to stop when the view ends. 
We were comparing past the end of the view, which was clearly not correct.

69a6ce90df AK: Add a ScopeGuard helper that invokes a callback when destroyed. 
This is useful when you want to ensure some little thing happens when you
exit a certain scope.

This patch makes use of it in LibC's netdb code to make sure we close the
connection to the LookupServer.

Conrad Pankoff
042895317d AK: Add AKString::split_limit to split strings with a limit 
This is a small change to the existing split() functionality to support
the case of splitting a string and stopping at a certain number of
tokens. This is useful for parsing e.g. key/value pairs, where the value
may contain the delimiter you're splitting on.

7bce096afd Take StringView in more places 
We should work towards a pattern where we take StringView as function

df74a9222f Kernel: Fix timeout support in select 
The scheduler expects m_select_timeout to act as a deadline. That is, it
should contain the time that a task should wake at -- but we were
directly copying the time from userspace, which meant that it always
returned virtually immediately.

At the same time, fix CEventLoop to not rely on the broken select behavior
by subtracting the current time from the time of the nearest timer.

This is off by default, but enabled by TextEditor. It simply inserts the
same number of leading spaces as the previous line when hitting Enter. :^)

44673c4f3b Kernel: Add a write cache to DiskBackedFS. 
This way you can spam small write()s on a file without the kernel writing
to disk every single time. Flushes are included in the FS::sync() operation
and will get triggered regularly by syncd. :^)

58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.

2d7cad6a16 Kernel: Make sure we don't use any FPU/MMX/SSE instructions. 2019-04-22 23:38:33 +02:00
Andreas Kling
6693cfb26a Kernel: Don't use MMX memcpy() in the kernel. 
I just discovered the hard way that clobbering FPU/MMX/SSE registers in the
kernel makes things very confusing for userspace (and other kernel threads.)

Let's banish all of those things from the kernel to keep things simple.

ab94a6be00 AK: Add String::copy(BufferType) helper. 
This will create a String from any BufferType that has data() and size().
 2019-04-20 14:13:40 +02:00
Andreas Kling
7faf8fabf2 AK: Give Vector the ability to have an inline capacity. 
This makes Vector malloc-free as long as you stay within the templated
inline capacity. :^)

Andreas Kling
301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__ 
This makes it a bit easier to use AK templates out-of-tree.

Andreas Kling
b41e95b578 Snake: Use a queue for the movement inputs. 
This makes it a lot less finicky to make rapid moves like staircasing and
sudden turns.

Andreas Kling
b985d0ec6e AK: Add RetainPtr::operator==() overload G++ is whining about. 2019-04-19 21:34:47 +02:00
Andreas Kling
3a33b8ea08 VisualBuilder: Hook up everything needed for widget property editing. 
It's now possible to edit widget properties inline in the properties window.
We're currently relying on the basic GVariant conversion functions to do
all the "parsing" but that's not gonna be good enough.

Andreas Kling
bc5148354f LibCore: Add a CConfigFile class, a simple INI file parser. 
You open the configuration for an app like so:

    auto config = CConfigFile::get_for_app("MyApp");

This will then open ~/MyApp.ini and parse it for you.
Immediately start using it in Minesweeper to load the field size and mine
count from a config file.

f93b3b7806 AK: Improve StringImpl chomping a bit. 
Chomp off any number of trailing [\0\n\r] characters and trim the allocation
to fit instead of keeping the original size.

Andreas Kling
47d270b577 WindowServer: Factor out window frame logic into a WSWindowFrame class. 
The window frame is an object that contains a window, its title bar and
window border. This way WSWindowManager doesn't have to know about all the
different types of window borders, titlebar rects, etc.

Andreas Kling
c02c9880b6 AK: Add Eternal<T> and use it in various places. 
This is useful for static locals that never need to be destroyed:

Thing& Thing::the()
{
    static Eternal<Thing> the;
    return the;
}

The object will be allocated in data segment memory and will never have
its destructor invoked.

Andreas Kling
56f7b392c1 WindowServer: Move the CPU usage graph updates to a secondary thread. 
This avoids blocking the main thread on filesystem access, which created
noticeable stutters during compilation.

Andreas Kling
23bb276fcd LibC: Run constructors on process startup. 
Cooperate with the compiler to generate and execute the _init_array list
of constructor functions on userspace program statup. This took two days
to get working, my goodness. :^)

86413a6f5a LibGUI+FileManager: Add a GIcon class to support multi-size icons. 
A GIcon can contain any number of bitmaps internally, and will give you
the best fitting icon when you call bitmap_for_size().

Andreas Kling
60d25f0f4a Kernel: Introduce threads, and refactor everything in support of it. 
The scheduler now operates on threads, rather than on processes.
Each process has a main thread, and can have any number of additional
threads. The process exits when the main thread exits.

This patch doesn't actually spawn any additional threads, it merely
does all the plumbing needed to make it possible. :^)

This doesn't have any server functionality just yet, but it does post
decent-looking DNS queries and parse the responses.

Andreas Kling
43304d2adf WindowServer: Add special treatment for modal windows. 
While a WSClientConnection has a modal window showing, non-modal windows
belonging to that client are not sent any events.
 2019-03-19 00:52:39 +01:00
Andreas Kling
214b67defd AK: Add Vector::remove_first_matching(Callback). 
This is a nice little helper to remove one item based on a matching
callback without having to do iteration yourself.
 2019-03-18 20:51:40 +01:00

9ad076178a GIODevice: Add a read_all() that returns a ByteBuffer with all we can read. 
Use this to implement file opening in TextEditor.
 2019-03-18 14:38:30 +01:00
Andreas Kling
ef05d8cbf6 AK: Use an OwnPtr for the VectorImpl. 
I don't know why it wasn't implemented this way already. This fixes a leak
in operator=(Vector&&) that we were hitting on Ext2FS write.
 2019-03-17 15:53:03 +01:00
Andreas Kling
1c6dfc3282 AK: Make ByteBuffer's copy() and wrap() take void*. 
This way we don't have to cast whatever we're passing to copy()/wrap().
 2019-03-17 00:36:41 +01:00
Andreas Kling
dd5ca1940a AK: Hoist the assertion in Retainable::release() to RetainableBase.

for each and every specialization.

Andreas Kling
15657f0916 AK: Remove Buffer<T> since it was only ever instantiated with T=byte. 
Instead make a specialized AK::ByteBufferImpl class for the backing store
of AK::ByteBuffer. This reduces template bloat.
 2019-03-16 13:12:13 +01:00
Andreas Kling
955a0ff477 AK: Reduce template bloat by hoisting non-typed parts of Retainable. 
This is a bit of an old school hack, but it does remove a whole bunch of
generated symbols.

Andreas Kling
0d5e6593b2 AK: Add a basic QuickSort template implementation. 
It was depressing not being able to capture anything when passing a lambda

this eventually anyway. :^)
 2019-03-09 16:20:12 +01:00

46caa2663b LibGUI: Use a separate data role for the table model sorting order.

Andreas Kling
7d1142c7d9 Make it possible to sort a GTableModel by column+order.
