Instead of building the web DOM by hand, we now load an empty document
into an OutOfProcessWebView, and then append things to it by sending
little snippets of JavaScript to the host process. :^)
This patch adds OutOfProcessWebView::run_javascript(StringView).
This can be used by the OOPWV embedder to execute arbitrary JavaScript
in the top-level browsing context on the WebContent process side.
The IRC Client application made some sense while our main communication
hub was an IRC channel. Now that we've moved on, IRC is just a random
protocol with no particular relevance to this project.
This also has the benefit of removing one major client of the single-
process Web::InProcessWebView class.
Added a test to ensure the behavior stays the same.
We now throw on a direct usage of an escaped keywords with a specific
error to make it more clear to the user.
You can now specify a number of iterations when timing a command.
The default value is 1 and behaves exactly as before.
If the iteration count is greater than 1, the command will be executed
that many times, and then you get a little timing report afterwards with
the average runtime per iteration, and also the average runtime
excluding the very first iteration. (Excluding the first iteration is
useful when it's slowed down by cold caches, etc.)
This is something I've been doing manually forever (running `time foo`
and then eyeballing the results to headmath an average) and this makes
that whole process so much nicer. :^)
This iterates the fragments of the containing block, and paints their
outlines if they are descendants of the InlineNode.
If multiple fragments are adjacent, eg:
```html
<span><b>Well</b> hello <i>friends!</i></span>
```
...then we get a double-thick outline between "Well", " hello " and
"friends!", but we can come back to this after we implement
non-rectangular outlines for the `outline` CSS property.
This opens the DOM Inspector window, with the target element already
selected. (If the window is already open, it just selects the element.)
Note that this only applies to single-process mode for now. In OOP mode,
the "inspect element" action is disabled.
This is an application analogous to WidgetGallery, in that it tests
various capabilities of LibGUI models. Right now it is pretty bare, but
as more work towards LibGUI models is done regarding persistent model
indices, more demos will be added.
Now you can specify a CursorTheme key in /etc/WindowServer.ini. The
cursors are loaded from /res/cursor-themes/<name> directory. This
directory contains a Config.ini file with format similar to previous
Cursor section, except it uses relative paths.
This commit adds also Default theme, which uses cursors being
previously in /res/cursors.
The WidgetGallery is updated to match the new cursor path format.
These should all have a name with an empty string. Not only does test262
verify this, but it also verifies that (for the executor) the name
property is defined after the length property.
PerformPromiseAll, PerformPromiseAny, PerformPromiseAllSettled, etc, all
have very similar iteration loops. To avoid duplicating this rather
large block of code, extract the common functionality into a separate
method.
The element-resolving functions on the Promise constructor are all very
similar. To prepare for more of these functions to be implemented, break
out common parts into a base class.
Prior this change, if user had more than two copies of one file opened
in a split view, then only the active editor was renamed,
when the others had the same file contents changed.
This change will set a new file name for every file.
The is_null() check is for uncreated files, as they shouldn't be
treated as the same single file.
This makes the editor title a bit more consistent with the other files
and removes duplicating the file name in the file history
when reopening that file.
In the DatabaseConnection constructor, there's a deferred_invoke
callback that references the client_id. But depending on when the
callback occurs, the reference of the client_id can change. This created
a problem when connecting to SQLServer using the SQL utility because
depending on when the callback was invoked, the client_id could change.
m_client_id is set in the constructor and that reference will not change
depending on when the callback is invoked.
Ctrl+Shift+Left would add the word before the cursor to the selection,
but for some reason Ctrl+Shift+Right didn't add the word after the
cursor to the selection.
The editor's on_change callback was being overwritten in
HackStudioWidget.cpp in order to call update_gml_preview on every
change. This stopped the original callback from being called and marking
files as dirty when changed.
Now we call update_gml_preview in a new callback within the editor
wrapper, which is then called within the original on_change callback
in the editor.
GitWidget no longer crashes upon trying to create a repository for a new
project, and it correctly updates after opening a different project. A
new method, change_repo, has been added to make this work, which changes
m_repo_root and resets most of the widget's state in order to make this
work.
Moved code to stop the debugger in the HackStudioWidget destructor to
a new method so that this can be called in both the destructor and when
opening a new project.
The ToDoEntries and ToDoEntriesWidget classes now have methods for
clearing the entries, before entries would stay permanently, even after
switching to a new project.
Added a close_file_in_all_editors method to HackStudioWidget and moved
the code from handle_external_file_deletion into it so that it can be
reused elsewhere to close files.
1. Move htonl() etc. from <arpa/inet.h> to <netinet/in.h> (which
<arpa/inet.h> includes).
The htonl(), htons(), ntohl(), and ntohs() functions shall be
available as described in <arpa/inet.h>. Inclusion of the
<netinet/in.h> header may also make visible all symbols from
<arpa/inet.h>.
- POSIX
2. Define IN6_IS_ADDR_LOOPBACK() and IN6_IS_ADDR_V4MAPPED()
For some reason X/OPEN requires that fd_set has a field fds_bits. Xproto
requires either fds_bits or _fds_bits to be present, so the field 'bits'
was renamed 'fds_bits'
This patch adds support for opening a ConfigFile using a file
descriptor rather than trying to open a the file by name directly.
In contrast to the previous implementation, ConfigFile now always keeps
a reference to an open File and does not reopen it for writing.
This requires providing an additional argument to open functions if a
file gets opened based on its name and the user of the api intends to
write to the file in the future.
Previously, the preprocessor first split the source into lines, and then
processed and lexed each line separately.
This patch makes the preprocessor first lex the source, and then do the
processing on the tokenized representation.
This generally simplifies the code, and also fixes an issue we
previously had with multiline comments (we did not recognize them
correctly when processing each line separately).
Classes reading and writing to the data heap would communicate directly
with the Heap object, and transfer ByteBuffers back and forth with it.
This makes things like caching and locking hard. Therefore all data
persistence activity will be funneled through a Serializer object which
in turn submits it to the Heap.
Introducing this unfortunately resulted in a huge amount of churn, in
which a number of smaller refactorings got caught up as well.
This patch provides very basic, bare bones implementations of the
INSERT and SELECT statements. They are *very* limited:
- The only variant of the INSERT statement that currently works is
SELECT INTO schema.table (column1, column2, ....) VALUES
(value11, value21, ...), (value12, value22, ...), ...
where the values are literals.
- The SELECT statement is even more limited, and is only provided to
allow verification of the INSERT statement. The only form implemented
is: SELECT * FROM schema.table
These statements required a bit of change in the Statement::execute
API. Originally execute only received a Database object as parameter.
This is not enough; we now pass an ExecutionContext object which
contains the Database, the current result set, and the last Tuple read
from the database. This object will undoubtedly evolve over time.
This API change dragged SQLServer::SQLStatement into the patch.
Another API addition is Expression::evaluate. This method is,
unsurprisingly, used to evaluate expressions, like the values in the
INSERT statement.
Finally, a new test file is added: TestSqlStatementExecution, which
tests the currently implemented statements. As the number and flavour of
implemented statements grows, this test file will probably have to be
restructured.
The implemtation of the Value class was based on lambda member variables
implementing type-dependent behaviour. This was done to ensure that
Values can be used as stack-only objects; the simplest alternative,
virtual methods, forces them onto the heap. The problem with the the
lambda approach is that it bloats the Values (which are supposed to be
lightweight objects) quite considerably, because every object contains
more than a dozen function pointers.
The solution to address both problems (we want Values to be able to live
on the stack and be as lightweight as possible) chosen here is to
encapsulate type-dependent behaviour and state in an implementation
class, and let the Value be an AK::Variant of those implementation
classes. All methods of Value are now basically straight delegates to
the implementation object using the Variant::visit method.
One issue complicating matters is the addition of two aggregate types,
Tuple and Array, which each contain a Vector of Values. At this point
Tuples and Arrays (and potential future aggregate types) can't contain
these aggregate types. This is limiting and needs to be addressed.
Another area that needs attention is the nomenclature of things; it's
a bit of a tangle of 'ValueBlahBlah' and 'ImplBlahBlah'. It makes sense
right now I think but admit we probably can do better.
Other things included here:
- Added the Boolean and Null types (and Tuple and Array, see above).
- to_string now always succeeds and returns a String instead of an
Optional. This had some impact on other sources.
- Added a lot of tests.
- Started moving the serialization mechanism more towards where I want
it to be, i.e. a 'DataSerializer' object which just takes
serialization and deserialization requests and knows for example how
to store long strings out-of-line.
One last remark: There is obviously a naming clash between the Tuple
class and the Tuple Value type. This is intentional; I plan to make the
Tuple class a subclass of Value (and hence Key and Row as well).
This is an interesting quirk that occurs due to us using the x87 FPU
when Serenity is compiled for the i386 target. When we calculate our
depth value to be stored in the buffer, it is an 80-bit x87
floating point number, however, when stored into the DepthBuffer,
this is truncated to 32 bits. This 38 bit loss of precision means
that when x87 `FCOMP` is eventually used here the comparison fails.
This could be solved by using a `long double` for the depth buffer,
however this would take up significantly more space and is completely
overkill for a depth buffer. As such, comparing the first 32-bits of
this depth value is "good enough" that if we get a hit on it being
equal, we can pretty much guarantee that it's actually equal.
The current flap strength makes the game a lot more difficult than
other flappy games. Decrease the flap strength to make it a little
easier to get higher scores.
Before this change I could only get past 3 or 4 obstacles, now I can
get 15 or 20 in, which seems more on par with other flappy games.
For example, consider the following pattern:
new RegExp('\ud834\udf06', 'u')
With this pattern, the regex parser should insert the UTF-8 encoded
bytes 0xf0, 0x9d, 0x8c, and 0x86. However, because these characters are
currently treated as normal char types, they have a negative value since
they are all > 0x7f. Then, due to sign extension, when these characters
are cast to u64, the sign bit is preserved. The result is that these
bytes are inserted as 0xfffffffffffffff0, 0xffffffffffffff9d, etc.
Fortunately, there are only a few places where we insert bytecode with
the raw characters. In these places, be sure to treat the bytes as u8
before they are cast to u64.
RegExp.prototype.compile will require invoking RegExpInitialize on an
already-existing RegExpObject. Break up RegExpCreate into RegExpAlloc
and RegExpInitialize to support this.
Currently just sets the renderer option for what polygon mode we
want the rasterizer to draw in. GLQuake only uses `GL_FRONT_AND_BACK`
with `GL_FILL` )which implies both back and front facing triangles
are to be filled completely by the rasterizer), so keeping this as
a small stub is perfectly fine for now.
With the new parser, we started interpreting the `opacity` property as a
string value, which made it turn into `auto` and so anything with
opacity ended up not visible (e.g the header on google.com)
This patch restores our old behavior for `opacity` by interpreting it
as a numeric value with optional decimals.
Load the wallpaper in a background action instead of on the main thread.
This reduces the time to first paint, and makes the UI feel more
responsive when clicking on wallpaper thumbnails.
The behavior of the method is changed slightly to return true if it
succesfully "loads" the empty path. This makes the API a little more
consistent, where "true" means "I made changes" and "false" means "I did
not make changes". No call sites currently use the return value, so no
changes are needed to those.
Instead of loading every icon, only load the filetype image icon if it
hasn't been already. This icon is used by IconViews that need to lazily
load thumbnails, which don't need any of the other icon types.
Spending the time to load the unneeded images was causing delays to
first paint in BackgroundSettings.
Prior this change, the window title was updated only when a new file
has been opened, which means that it wasn't updated when user selected
an already opened file in the split view.
This change updates the title whenever the active editor changes.
In addition, this title update logic has now its own function
as it'll also be used in the next commit. :)
For example, "property.br\u{64}wn" should resolve to "property.brown".
To support this behavior, this commit changes the Token class to hold
both the evaluated identifier name and a view into the original source
for the unevaluated name. There are some contexts in which identifiers
are not allowed to contain Unicode escape sequences; for example, export
statements of the form "export {} from foo.js" forbid escapes in the
identifier "from".
The test file is added to .prettierignore because prettier will replace
all escaped Unicode sequences with their unescaped value.
Unfortunately, this requires a slight divergence in the way the capture
group names are stored. Previously, the generated byte code would simply
store a view into the regex pattern string, so no string copying was
required.
Now, the escape sequences are decoded into a new string, and a vector
of all parsed capture group names are stored in a vector in the parser
result structure. The byte code then stores a view into the
corresponding string in that vector.
This will allow regex::Lexer users to invoke GenericLexer consumption
methods, such as GenericLexer::consume_escaped_codepoint().
This also allows for de-duplicating common methods between the lexers.
This is primarily to be able to remove the GenericLexer include out of
Format.h as well. A subsequent commit will add AK::Result to
GenericLexer, which will cause naming conflicts with other structures
named Result. This can be avoided (for now) by preventing nearly every
file in the system from implicitly including GenericLexer.
Other changes in this commit are to add the GenericLexer include to
files where it is missing.
It can sometimes be difficult to tell from the debug.log and test stdout
which test was the last to run before the test runner hangs or exits the
QEMU instance unexpectedly.
Print out a start message before each test is executed, along with a
progress message indicating which test out of how many tests we're about
to run.
This patch prevents CppComprehensionEngine from endlessly looping when
there's a circular #include in the code.
We now keep track of the set of currently processed files, and will not
re-process a file if it already exists in this set.
When we're done with processing a file it is removed from this set.
The pragma once directive is not yet implemented, but regardless a
mechanism that prevents #include loops even in the absence of
pragma once is desired.
This brings `glGetFloatv` more inline with the other `glGet`
functions. We should prevent crashing in the driver as much as
possible and instead let the application deal with the generated
GL error.
Instead of constructing a String and converting that to a PropertyName
on the fly, we can just leverage CommonPropertyNames, add a couple more
and directly pass ready-to-use PropertyNames with pre-allocated Strings.
Otherwise, we emit a menu_item_left to the WindowServer client even
though the mouse never left the menu item (as is the case when a
disabled menu item is clicked).
Since we operate in screen space where y points down we need to reverse
what is considered clock wise and what is considered counter clockwise.
The rasterizer always expects triangles with a consistent winding order
thus swap 2 vertices if necessary to reverse the winding before passing
the triangle on to the rasterization stage.
The previous clipping implementation was problematic especially when
clipping against the near plane. Triangles are now correctly clipped
using homogenous coordinates against all frustum planes.
Texture coordinates and vertex colors are now correctly interpolated.
The earier implementation was just a placeholder.
GL_VERSION: The spec mandates the following format: x.y or x.y.z
optionally followed by text separated by space.
GL_EXTENSIONS: Return empty string. We do not support any extensions.
glTexCoord should behave like glColor. It only updates a gl context
variable that contains the current texture coordinates. The vertex is
only actually created once glVertex is called.
aplay would previously just retry a couple of times when the loader
encountered an error, even though there is a standard mechanism for
loaders to report errors. Now, aplay outputs these errors to the user
and exits.
FlacLoader initialized, but never used its resampler; this is now fixed
and all subframes are resampled before decorrelation occurs. FLAC files
with non-44100-Hz sample rates now play properly.
Floating-point ratios are inherently imprecise, and can lead to
unpredictable or nondeterministic behavior when resampling and expecting
a certain number of resulting samples. Therefore, the resampler now uses
integer ratios, with almost identical but fully predictable behavior.
This also introduces the reset() function that the FLAC loader will use
in the future.
Since readdir() actually gives us the file type, we don't have
to stat it again to know whether it's a directory! This means that
'find /' can process the majority of files without ever calling
stat() on them, simply by reading directories.
In addition, the TypeCommand (-t) can make use of this info too,
so, for instance, a 'find / -t d' does not need to stat anything
either.
This gives us a final huge speedup :^)
We have multiple commands that are implemented in terms of stat.
Let's cache the stat in FileData after we query it once.
This gives us another large speed-up :^)
While Core::DirIterator is nice C++ API, we want more low-level
control here. In particular, we want to open the directory using
openat(), to also not pay the cost of re-traversing the path
components we have already resolved previously.
This gives us another nice speedup :^)
Also, in the future commits this will allow us to make use of more
data from the returned struct dirent, to speed things up even further.
This speeds things up noticeably :^)
The idea here is that a directory fd is a way to hold onto
the results of path resolution that the kernel has already done
for us. This way we don't ask the kernel to resolve the same
parent directories over and over.
