* While this breaks binary compatibility with earlier Haiku releases,
use values that are less likely to clash with actual use cases.
* Specifically, using a negative spacing is one way to get rid of the
border of BScrollViews, to put them into a window neatly.
* Also, BControlLook now uses a switch to resolve them.
* This has been necessary due to the undefined call order of
of static objects. Fixes #12315.
* The bug has been caused by the linker which free unused resources,
making the BMediaRoster to run in a zombie state. In this state
anything such as a message could make the looper to crash.
* The class is reintroduced with some differences though, we are
going to protect it from another thread calling Roster() while the
BMediaRoster is quitting and implement BMediaRosterEx::Quit.
* Unregister registrar notifications before we quit our thread. Avoid
to uninitialize anything from QuitRequested as it may cause problems.
The POSIX standard requires us to allow assert.h to be included multiple
times with differnt values of NDEBUG. So we can't have a global header
guard on the files. However, we must also make sure that we don't
declare functions multiple times in that case. Re-introduce an header
guard on the part of the file where we declare functions, only.
Fixes lots of warnings when building Netsurf.
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.
* 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.
2 concrete classes which are currently implemented:
* BSpinner (works on int32s)
* BDecimalSpinner (works on doubles)
In addition BAbstractSpinner now inherits from BControl instead of
BView/BInvoker. This allowed for code simplification at the cost of needing to
cast for the decimal version because SetValue(int32 value) comes from BControl.
Also, add a spinner_button_style enum with 3 options:
* SPINNER_BUTTON_HORIZONTAL_ARROWS
* SPINNER_BUTTON_VERTICAL_ARROWS
* SPINNER_BUTTON_PLUS_MINUS
which sets the spinner arrows to either use horizontal arrows (left/right)
vertical arrows, (up/down), or +/- symbols (the default).
If the spinner button is using horizontal arrows you can decrement and increment
the spinner value by pushing control+left/right, otherwise you can increment and
decrement by pushing up or down. The reason for needing control is so that you
can move the cursor in the textbox otherwise.
Switch the 3 apps that are currently using BSpinners to use the integer variety
in Deskbar preferences, WebPostive preferences, and Screen preferences.
It provides a way for filesystems to cache a lookup failure and
therefore prevents repeated lookups of missing entries. This is a
common scenario for example in command lookup and compiling, where
each directory in PATH or each include directory is searched for the
given entry.
The individual debug heap implementations are now exposed via a
structure of function pointers and a common frontend dispatches the
malloc and malloc_debug APIs through them.
The MALLOC_DEBUG environment variable can be used to select the guarded
heap by adding 'g', otherwise the debug heap is used as the default.
Consequently the separate libroot_guarded is not needed anymore and has
been removed.
To allow the use of environment variables this early, init_env_post_heap
has been added and the heap dependent atfork() moved there. This allowed
to fold the code of init_heap_post_env into init_heap so the former has
been removed.
* Killing the thread leaks resources, and it will terminate cleanly and
safely when the destructor exits anyway.
* Fixes #12293. Thanks to ttcoder, jackburton and bonefish for investigating!
* Does not fix #12286. Going to bissect now...
* The first problem was the O(n^2) complexity of the algorithm, it's
now linear and try to act in a circular way by dispatching
events and reading the port in a balanced way. This exclude
a certain degree of possible deadlocks.
* Add detection and escape when the system try to kill the
thread. This solve some blocking issues on exit et similia
that i had with libjackcompat.
* The algorithm choose soon which event to focus on.
* Lateness is calculated just before the event is dispatched
as it is the more appropriate place, otherwise we would be
calculating something imprecise/guessed.
* Remove timed_event_queue::queued_time. It's more precise to
just use the RealTime() before to Dispatch the event.
* It should solve the BSoundPlayer lateness problems.
* With those improvements the media_kit is not going to lock
completely under stress conditions, instead it try to work
in a best effort shape.
* There's still room for improvements, for example i'm considering some
strategies in lateness situations such as update scheduling latency,
try to decrease waiting time and detect when we are too early on
the other hand to recover when the load go down.
* Thanks to Julian Harnath for sharing his WIP patch which helped
with some controls such as avoiding negative lateness.
* Comments are welcome!
* B_AUTO_UPDATE_SIZE_LIMITS only really makes sense for resizable
windows, and it only sets the minimum/maximum window size.
* ResizeToPreferred() resizes the window to its preferred size, and
also supports height-for-width layouts.
* Due to the needs to provide a peaceful UX, i moved out the
notifications mechanism from the Media preflet and i have
integrated it with the launch and shutdown functions of MediaDefs.h.
* This implied to introduce a new launch_media_server function
similar to the shutdown_media_server allowing to specify a custom
notification function too.
* Both functions then are reworked to send by default notifications
to the Deskbar, this was needed because in a lot of situations
the mechanism failed without correctly noticing the user.
* The one argument launch_media_server is considered to be deprecated,
the default argument is removed to mantain binary compatibility but
make new apps to automatically use the new one with just the default
arguments. This is needed due to conflicts in overloading.
* Improve notifications by indirectly extending localization
to old BeOS apps.
* Add new methods
BView::BeginLayer(uint8 opacity)
BView::EndLayer()
* All drawing between begin and end of a layer is redirected onto an
intermediate bitmap. When ending the layer, this bitmap is
composited onto the view with the opacity given when the layer was
started.
* Layers can be nested arbitrarily and will be blended onto each
other in order. There can also be any arbitrary interleaving of
layer begin/end and drawing operations.
* Internally, drawing commands are redirected into a BPicture between
BeginLayer and EndLayer (but client code need not know or care
about this). Client code can also start/end other BPictures while
inside a layer.
* Uses the PictureBoundingBoxPlayer to determine the size of the
layer bitmap before allocating and drawing into it, so it does not
allocate more memory than necessary and -- more importantly -- it
will not alpha-composite more pixels than necessary.
* Drawing mode is always set to B_OP_ALPHA, blend mode to
(B_PIXEL_ALPHA, B_ALPHA_COMPOSITE) while inside layers. This is
necessary for (a) correct compositing output and (b) for
redirection of drawing into the intermediate bitmap, which uses the
renderer_region offset (in B_OP_COPY, the Painter does not use the
AGG renderer methods, it directly accesses the pixel data. This
would access out-of-bounds without the offset, so B_OP_COPY cannot
be allowed.)
To ensure these modes aren't changed, BView::SetDrawingMode()
and BView::SetBlendingMode() are ignored while inside a layer.
* The main motivation behind this new API is WebKit, which internally
expects such a layers functionality to be present. A performant and
reusable implementation of this functionality can only be done
server-side in app_server.
* This is done by watching to registrar notifications
and providing a minimal service to contact the
media roster in private API. The roster use this
service to automatically reconnect to the media_server.
* Improve consistency by adding a BMediaRosterEx destructor
and using it for the specular functionality of ctor instead
to use the father's class destructor.
* Avoid double initialization of MediaInitializer that
becomes MediaRosterUndertaker.
* Remove superfluos call to BMediaRoster::Quit()
in media_addon_server.
* This closes #12114 again; while not POSIX, it's just a line away.
* Removed exect() from the header -- not sure where this came from.
but I can't find anything about it on the net.
* Consolidated use of asterisk style in exec.cpp.
For defining the text that appears alongside the icon.
This function really has too many parameters; we probably should break
it out into a BAction class...
* This also fixes the shutdown process, as the registrar no longer
kills the app_server.
* Removed SERVER_PORT_NAME definition as it has no use anymore.
* When creating the port of the registrar's authentication manager, we
now set it manually, so that the user/group functions work.
* This allows LaunchDaemon::_StartSession() to set up the user, and
groups as needed.
* Instead, the caller should have done this already. This is really
outside of the scope of the launch_daemon.
* Fixed Login with empty passwords; removed the (unused) test login
feature along the way.
* You can now add arbitrarily named fields to the message as well,
without having them all specified in the template.
* Also added a missing converter method that is called when there
are no values to add, and implemented all methods in the base
class, so that you only have to implement the methods you actually
need.
* BRoster now allows settings a "no-registrar" mode that is currently
only honored in _LaunchApp(), though.
* Job::Launch() is now using this, which also allows launching
applications by signature (ie. if the job name matches the
signature, you can omit the "launch" option).
* You can now put jobs/services into a target.
* Instead of having Login started as part of the normal boot process,
it's now in the "login" target.
* The app_server now launches the login target when a login becomes
available (ie. during startup, but that could be improved later on).
* Instead of launching Tracker/Deskbar directly, we now launch the
Login application.
* This will now start a new session for the selected user (the password
is currently ignored).
* When a user session is started, the launch_daemon forks, and the
child then restarts the LaunchDaemon application in user mode.
* It then registers itself with its parent, in order to resolve user
dependent services.
* Added a user launch file that will cause Tracker, and Deskbar to
start in the new session.
* get_roster_port_name() is no longer needed.
* This also removes the app_server restart code from the debug
server -- this will be done by the launch_daemon in the future.
* Instead of letting the kernel search for the syslog port, the
daemon now registers itself with the kernel (which even solves
a TODO).
* A port is created for the actual log messages from the launch_daemon,
and used on start.
* However, the SyslogTest does not yet work, due to the BMessage <->
KMessage communication problems.
* These methods don't really work yet, as BMessage doesn't support
replying with a KMessage; the request is received, but the reply
never gets to the target.
