This fixes some precision issues in Painter::draw_triangle()
that caused the Cube demo to leave pixels empty between triangles
under certain angles.
Also adds some extra comments for clarity and early returns when
parts of the triangle do not need to be drawn.
It was previously using draw_tiled_bitmap, which always aligns the
tiles with the global origin and does not respect the alpha of the
source. Switch to a new Painter::blit_tiled helper which uses
Painter::blit under the hood, which has more correct behavior.
We now restart the language server transparently if it crashes.
If the language server crashes too frequently (current threshold is
twice within 3 seconds), we give up and will not attempt to restart it
again. HackStudio will still work fine, but features that depend on the
language server will not function.
To support this change we use a new class, 'ServerConnectionWrapper',
that holds the actual ServerConnection and is responsible for restarting
the language-server if it crashes.
Closes#5574.
- FileDB::get() now returns nullptr if the file is not in the FileDB
- Added FileDB::get_or_create_from_filesystem()
- Added FileDB::add() version that receives that file's content as a
parameter
This fixes an issue were "Find in Files" would not use the up-to-date
content of a file with unsaved changes.
The issue existed because 'FindInFilesWidget' uses
Project::for_each_text_file, which retrieves files by their absolute
path. However, when a file is opened in an Editor, it is created with
a relative path.
This caused us to store two ProjectFile objects that refer to the same
file - one with a relative path and one with an absolute path.
HackStudio keeps a map that stores the different ServerConnection
instances we have open.
Previously, that map was indexed by a project's root path.
This did not make much sense because we only support opening a single
project with each instance of the HackStudio program.
We now index the different ServerConnections by the language name, which
allows us to support talking to multiple language-servers in the same
project (e.g C++ and Shell).
This also fixes an issue where if you first opened a Shell file, and
then a C++ file in the same project, then C++ language-server features
would not work.
And delete the generic icon member which has been dormant since
switching to FileIconProvider. Fixes icon column not being properly
painted as icon cells.
Add Bitmap::view() and forward most of the calls to BitmapView since
the code was identical.
Bitmap is now primarily concerned with its dynamically allocated
backing store and BitmapView deals with the rest.
This makes them available for use by other language servers.
Also as a bonus, update the Shell language server to discover some
symbols and add go-to-definition functionality :^)
Mostly due to the fact that clang-format allows aligned comments via
AlignTrailingComments.
We could also use raw string literals in inline asm, which clang-format
deals with properly (and would be nicer in a lot of places).
This commit removes the only 3rd party library (and its usages)
in serenity: puff, which is used for deflate decompression. and
replaces it with the existing original serenity implementation
in LibCompress. :^)
This is a little bit messy, but basically if an ELF object is non-PIE,
we have to account for the executable mapping being at a hard-coded
offset and subtract that when doing symbolication.
There's probably a nicer way to solve this, I just hacked this together
so we can see "cc1plus" and friends in profiles. :^)
In multi-process profiles, the same ELF objects tend to occur many
times (everyone has libc.so for example) so we will quickly run out
of VM if we map each object once per process that uses it.
Fix this by adding a "mapped object cache" that maps the path of
an ELF object to a cached memory mapping and wrapping ELF::Image.
Extracted a method from the code in the File Manager application which
added actions for activating launch handlers found for the selected
file from the context menu. Applied this method to desktop files
and shortcuts.
Note: made some launch handler related methods in the DirectoryView
static or const which allows passing const DirectoryView& to certain
methods.
Because the z-order changes we not only need to recompute occlusions
but we also need to mark the screen area of the previous and new
highlighted window as dirty.
Fixes#5599
The perfcore file format was previously limited to a single process
since the pid/executable/regions data was top-level in the JSON.
This patch moves the process-specific data into a top-level array
named "processes" and we now add entries for each process that has
been sampled during the profile run.
This makes it possible to see samples from multiple threads when
viewing a perfcore file with Profiler. This is extremely cool! :^)
When you reset() a Track, you need to set the piano roll iterators back
to the first notes.
Fixes#2578. The bug was due to pressing export between 2 notes - the
tracks were never told to go back to the first note.
