Long application signatures and paths could previously take up too much
space, causing the buttons to be cut off or become completely invisible.
Actually fixes #11367.
The application is now launched suspended and the ports are created
and transferred to the launched team before its main thread is
resumed.
The ports are therefore owned by the launched team instead of the
launch_daemon. This is important when sending messages by area, as
the port owner is used to determine where the data area needs to be
transferred to. This commit therefore fixes #12285.
Note that it is still possible to get at the ports with find_port()
while they are still owned by the launch_daemon. This should not be a
problem however, as these ports are not supposed to be found this way
but only through BLaunchRoster::GetData(), which is synchronized with
the above process.
Creating the ports in the launch_daemon still has the benefit of
returning valid communication ports earlier, i.e. without having to
wait for the launched application to actually become ready.
It allows to launch the app, but keep its main thread suspended instead
of automatically resuming it.
Also add appThread argument which allows to retrieve the main thread of
the launched team.
* TRANSITION_... was incorrectly changed from the original patch.
* Divided it into two constants, and also prefixed the new constants with
the register fields they are valid for.
* Fixed incorrect usage of |= and removed the corresponding TODO comments.
* Moved some reoccurring code into their own methods.
* Added check for the ST bit in the command register for the interrupt
hard reset, too.
* This closes ticket #12295, thanks Anarchos!
Previously the LaunchDaemon would send out its own team id when a given
job was not yet launched, leading to invalid BMessengers once the port
owner changed to the actually launched team.
The launch of the target team and the launch data replies were also not
synchronized, which could lead to the launched team getting a reply
pointing to the launch_daemon when requesting data for itself. This is
the case for the BRoster init of the registrar. The fix in hrev49561
therefore didn't always work, because the registrar would sometimes get
the launch_daemon team id instead of the id of itself. It would later
try talking to the launch_daemon, which obviously never replied, leading
to #12237.
The LaunchDaemon now delegates the launch data reply to the Job instead.
The Job either replies directly, in case it has already been launched,
or queues the reply for when the launch completes. This causes launch
data requesters to block until the launch attempt is completed, but
won't block the LaunchDaemon message loop.
This commit introduces the seperate fLaunchStatus to properly handle the
ambiguity of fTeam being < 0, which is the case for both, when no launch
was attempted and when the launch failed. This new field now determines
what IsLaunched() returns and how launch data replies are handled.
The new launch status is additionally protected by the launch status
lock, which will later probably be made broader in scope to protect
against race conditions once service monitoring is implemented.
Renamed box label from "SoundFont" to "Available SoundFonts", hopefully
improves the user experience by making it clearer that this is a list
of the available soundfonts.
When no midi settings file was available, BSoftSynth should use the well known
TimGM6mb.sf2 soundfont. This wasn't working, since the code looked in the wrong
path (we have to append "synth" to the path returned by find_directory).
In case this SF is not present, now we try harder not to fail, and look for any
soundfont available in the system and user directories.
Fixes ticket #12325 although the selected soundfont is not written to the
user settings file.
The extra quotes aren't needed and cause problems when not parsed
through a shell. For example LD_PRELOAD which is handled by the
runtime_loader directly failed to work as there was no way to remove
the extra single quotes.
Note that quotes and single quotes can still be added to the variables
through respective quoting in the driver settings syntax.
Previously the thread member was overwritten with the freeing thread
when a page was freed, leading to confusion when hitting unallocated
pages due to the debugger message still stating "allocated by thread".
Track the freeing thread separately as it might be interesting to know
both, which thread initially allocated and which thread eventually freed
an allocation.
When the MimeUpdateThread is done, it marks itself as finished and
notifies the thread manager to clean up finished threads. Since multiple
such threads might finish at the same time and trigger the cleanup
notification, other threads that already marked themselves finished but
haven't actually exited yet might already be deleted and removed. This
would then lead to a use-after-free when they subsequently tried to send
their own cleanup message.
To solve the race condition, the thread manager will now wait for the
thread to actually exit before cleaning it up.
The introduction of the launch_daemon has made this race condition more
likely due to more applications starting in parallel, each triggering a
CreateAppMetaMimeThread which is a subclass of MimeUpdateThread. This
commit might therefore fix #12237.
* Refactor AlphaMask class to separate the mask from its source. This
allows use to not just a BPicture as source for a pixel alpha mask,
but also e.g. a BShape in the future (not yet implemented).
* For BPicture-based masks, use the PictureBoundingBoxPlayer to
determine the size of the resulting mask bitmap. The masks are now
drawn into bitmaps of this size (instead of the whole view size).
When alpha masks are stacked, their bounding rectangles intersect
(i.e. masks further up in the stack can never be larger than masks
lower in the stack). The bitmap of a mask always contains the state
of itself blended with all masks in the stack below it.
This also avoids frequent rerendering of the masks. They are now
independent of view size. When the view origin (in screen
coordinates) changes we only have to reattach the mask buffer,
without having to redraw it.
* The class UniformAlphaMask is used for simple masks with the same
alpha value in all pixels, it uses no mask bitmap at all.
Currently, it can only be used on its own and not be stacked
together with other mask types.
* Make test-app_server work again in a launch_daemon environment
* test_registrar gets a separate signature and port name again so the
host system can distinguish it from the system registrar
* AppServer is normally a BServer now, however, there can't be two
BApplications in one team. A class TestServerLoopAdapter is added,
which becomes the base class of AppServer instead of BServer when
compiling for libbe_test. It's an adapter class which looks towards
AppServer as it if was a BServer, but internally it is derived from
MessageLooper (like the old AppServer before the transition to
BServer).
This way, AppServer can stay a BServer in normal builds and it also
avoids having to use too many #ifdefs to distinguish the two
versions.
* Same concept as the previously exisiting drawing mode
implementations for e.g. pixel alpha overlay mode: when pattern
is solid, provide a separate mode implementation which does no
unnecessary pattern pixel lookups. This provides a considerable
speedup in composite mode when no stipple pattern is used.
* Add support for pixel alpha overlay mode in the optimized bilinear-
scaled bitmap drawing code of BitmapPainter.
For now, only BilinearDefault supports this. DrawBitmapBilinear
gets the colour type and draw mode as template parameters to
minimize code duplication and allow simple extension with further
pixel formats and modes.
Avoids, for this mode, fallback to the slower generic
AGG-pipeline-based version.
* Add another mode to DrawBitmapNoScale for drawing bitmaps using
B_OP_COPY with alpha masks. It behaves like the definition for
ClipToPicture from the BeBook: pixels with alpha = 0 are ignored,
pixels with any alpha > 0 are copied.
Before, this fell back to the slower generic AGG-pipeline-based
version.
* Some light refactoring
