Now there's only one thing left in ColumnMetadata: the initial width.
|
|
|
|
This gets rid of one field in ColumnData. The goal is to get rid of all
fields and lose ColumnData entirely.

If the cursor happened to be blinking in the invisible state, it would
take 500ms before we actually see the cursor in a newly focused editor
widget. This patch makes it show up right away.
|
|
It feels really awkward if nothing is focused when opening a window.
|
|
Right now the default is an empty value, which we accidentally exposed
in set{Interval,Timeout}() by not providing a custom this value, which
should't happen at all. Let's just make it a required argument instead.

...instead of handing out null / undefined / empty values.

We can't really share this stuff with TreeView anyway, since tables
and trees have very different spatial relationships between indexes.
|
|
This makes TreeView a lot more keyboard friendly.

Coming soon to a Browser Market Share graph near you! :^)

You can now pass a dictionary of request headers when starting a new
download in ProtocolServer.
The HTTP and HTTPS protocol will include the headers in their requests.

To achieve this, the API was tweaked a bit to allow for easier tracking
of completions.
This API change is non-disruptive to any application that does not use
anchored styles.
|
|
This commit also adds the concept of "anchored" styles, which are
applied to a specific part of the line, and are tracked to always stay
applied to that specific part.
Inserting text in the middle of an anchored style extends it, and
removing the styled substring causes the style to be removed as well.

Currently we would assert. Also make it case sensitive.
|
|
Apparently that's allowed and the RFC is just unclear about it.
Some servers seem to zero-pad the chunk size for whatever reason, and
previously, we interpreted that as the last chunk.

Replace codepoint variable type from char to u32.

Convert HTML escaped (&#XXX;) characters to string.

I've written a large part of the new stdio, so I'm (partly) to blame for it now.
|
|
I accidentally broke this in the recent rewrite. This reinstantiates the
behavior implemented in https://github.com/SerenityOS/serenity/commit/65714685259d1ea4ba9d32bc41aee6fc8c56a645.

LibLine should ultimately not care about what a "token" means in the
context of its user, so force the user to split the buffer itself.
This also allows the users to pick up contextual clues as well, since
they have to lex the line themselves.
This commit pacthes Shell and the JS repl to better handle completions,
so certain wrong behaviours are now corrected as well:
- JS repl can now complete "Object . getOw<tab>"
- Shell can now complete "echo | ca<tab>" and paths inside strings

Make sure that userspace is always referencing "system" headers in a way
that would build on target :). This means removing the explicit
include_directories of Libraries/LibC in favor of having it export its
headers as SYSTEM. Also remove a redundant include_directories of
Libraries in the 'serenity build' part of the build script. It's already
set at the top.
This causes issues for the Kernel, and for crt0.o. These special cases
are handled individually.

This is __cxa_guard_acquire, __cxa_guard_release, and __cxa_guard_abort.
We put these symbols in a 'fake' libstdc++ to trick gcc into thinking it
has libstdc++. These symbols are necessary for C++ programs and not C
programs, so, seems file. There's no way to tell gcc that, for example,
the standard lib it should use is libc++ or libc. So, this is what we
have for now.
When threaded code enters a block that is trying to call the constructor
for a block-scope static, the compiler will emit calls to these methods
to handle the "call_once" nature of block-scope statics.
The compiler creates a 64-bit guard variable, which it checks the first
byte of to determine if the variable should be intialized or not.
If the compiler-generated code reads that byte as a 0, it will call
__cxa_guard_acquire to try and be the thread to call the constructor for
the static variable. If the first byte is 1, it will assume that the
variable's constructor was called, and go on to access it.
__cxa_guard_acquire uses one of the 7 implementation defined bytes of
the guard variable as an atomic 8 bit variable. To control a state
machine that lets each entering thread know if they gained
'initialization rights', someone is working on the varaible, someone is
working on the varaible and there's at least one thread waiting for it
to be intialized, or if the variable was initialized and it's time to
access it. We only store a 1 to the byte the compiler looks at in
__cxa_guard_release, and use a futex to handle waiting.

This allows operator new and operator delete to be available to anyone
that links -lc (everyone) rather than just people that include
kmalloc.h (almost no one).
|
|
The new version uses buffering much more prominently, and hopefully performs
better. It also uses something resembling C++ rather than plain C.
|
|
We would want it to work with only stdio pledged.
|
|
This seems like a better compromise between throughput and latency, and
it doesn't _really_ affect the performance, so let's just compromise.
|
|
|
|
Technically the property descriptors for these should not have
"writable: true" but "get" and "set" instead - but we don't support that
yet.

This allows all the unicode processing to be internal to the line
editor.
|
|
This patchset drops the write notifier, and schedules writes only when
necessary.
As a result, the CPU utilisation no longer spikes to the skies :^)
