This patch adds these API's:
- pthread_mutex_init()
- pthread_mutex_lock()
- pthread_mutex_unlock()
No mutex attributes are supported yet, so we only do the simplest mutex
wihout recursive locking.
It's now possible to block until another thread in the same process has
exited. We can also retrieve its exit value, which is whatever value it
passed to pthread_exit(). :^)
This patch adds pthread_create() and pthread_exit(), which currently
simply wrap our existing create_thread() and exit_thread() syscalls.
LibThread is also ported to using LibPthread.
The Launcher's functionality has been replaced by the app shortcuts in
the system menu.
There were various window management hacks to ensure that the launcher
stayed below all other windows while also being movable, etc.
POSIX's openat() is very similar to open(), except you also provide a
file descriptor referring to a directory from which relative paths
should be resolved.
Passing it the magical fd number AT_FDCWD means "resolve from current
directory" (which is indeed also what open() normally does.)
This fixes libarchive's bsdtar, since it was trying to do something
extremely wrong in the absence of openat() support. The issue has
recently been fixed upstream in libarchive:
https://github.com/libarchive/libarchive/issues/1239
However, we should have openat() support anyway, so I went ahead and
implemented it. :^)
Fixes#748.
This just copies the short char into the wide char without any decoding
whatsoever. A proper implementation should look at the current LC_CTYPE
and implement multi-byte decoding.
To protect the layout system from negative input values, we were using
an empty Rect() whenever an empty rect (width/height <= 0) was provided
to set_relative_rect().
This caused Terminal's scrollbar code to fail, since it relies on first
setting only the scrollbar width on startup, and then setting up the
proper geometry in response to the initial resize event.
Fixes#753.
You can now register a GWidget subclass with REGISTER_GWIDGET(class)
and it will be available for factory construction through the new
GWidgetClassRegistration interface.
To obtain a GWidgetClassRegistration for a given class name, you call
GWidgetClassRegistration::find(class_name). You can also iterate over
all the registered classes using GWCR::for_each(callback).
This will be very useful for implementing a proper GUI designer, and
also in the future for things like script bindings.
NOTE: All of the registrations are done in GWidget.cpp at the moment
since I ran into trouble with the fricken linker pruning the global
constructors this mechanism relies on. :^)
GTreeView was forgetting to call to base in did_update_selection().
This prevented GAbstractView from firing the on_selection hook and we
ended up with only the on_selection_change hook firing.
There's currently a small paint glitch for vertical toolbars due to the
way StylePainter::paint_surface() draws a MidGray line at the bottom of
whatever a "surface" is supposed to be.
You can now press Ctrl+Shift+Up/Down in a GTextEditor and the currently
selected line(s) will all move together one step up/down.
If there is no selection, we move the line with the cursor on it. :^)
Since on_change handlers can alter the text document we're working on,
we have to make sure they've been run before we try looking at spans.
This fixes some flakiness when a paint happened before HackStudio had
a chance to re-highlight some C++ while editing it.
The design where clients of GTextEditor perform syntax highlighting in
the "arbitrary code execution" on_change callback is not very good.
We should find a way to move highlighting closer to the editor.
