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...
* 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.
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.
* Dropped "create_port" -- this is now the default for services.
* Additionally (or alternatively, if you use the "legacy" mode), you can
now create named ports, and specify their capacity.
* Added convenience methods to BLaunchRoster that automatically use the
signature of the current be_app.
* BRoster::Launch() cannot be used (yet), as it pre-registers the
application we're launching, and that won't work for the registrar or
anything else until the registrar is up and running.
* Renamed B_GET_LAUNCH_CONNECTIONS to B_GET_LAUNCH_DATA.
* Add the team ID to the get-launch-data reply.
* Added BLaunchRoster::GetPort() for convenience.
* Removed some superfluous debug output, but temporarily dump all stdio
to /dev/dprintf (ie. the syslog).
* Made job matching case insensitive (as MIME types should be).
* This enables a mechanism to profile almost the complete boot process
(starting with main2()), if SYSTEM_PROFILER is defined to 1.
* You can access the profiling data using "profile -r".
* This will be heavily inspired by Apple's launchd, as well as
systemd -- for now it really doesn't do a whole lot, though.
* What works so far: the configuration files are read, parsed, and
the jobs created.
* The jobs are even initialized, and their message ports created.
* BApplication now retrieves a previously created port from the
launch_daemon for use with BServer.
* Only the registrar actually uses this for now.
BColumnListView:
- Add helper method for getting the visible rect of a given field.
Refactor SuggestTextPosition to use it.
{Tree,Table}:
- Add wrapper to retrieve table cell rect using the aforementioned
BCLV helper.
The media_server is now able to remember the timesource associated to
a certain registered_node and always remove it when the owner
application crash, Fixes Ticket #11852
* Was leaking fQueuedJobs on destruction.
* fHaveRunnableJobSem implementation was not completed; it was never
released.
* Added Pop() variant that is a bit more flexible, and allows for a
timeout as well as waiting even when the queue is empty, and can
return a status code.
* Fixes sharing semantics, so non-shared semaphores in non-shared
memory do not become shared after a fork.
* Adds two new system calls: _user_mutex_sem_acquire/release(),
which reuse the user_mutex address-hashed wait mechanism.
* Named semaphores continue to use traditional sem_id semaphores.
* Put it in the BSupportKit namespace, following the style introduced
with the package kit for now.
* The BSupportKit::BJob class no longer knows about the package kit's
Context class. However, the BPackageKit::BJob class does.
* Due to the namespace juggling, a lot of files had to be touched.
* The JobQueue class remains private.
* Due to the way Haiku is built on itself, you cannot build this change
under Haiku with an older release.
* When you receive a message from a KMessage, and reply to it,
it will automatically reply as KMessage, too.
* This allows to communicate with BLoopers from within the kernel
or libroot.so.
The AddOnManager was in the global namespace, clashing with application
classes with the same name.
The input_server has an AddOnManager of its own. When the
shortcut_catcher filter was loaded by said AddOnManager, it in turn
loaded libgame.so, which in turn loaded libmedia.so, where an
AddOnManager was created for the global AddOnManager instance in
libmedia.so. Unfortunately the wrong AddOnManager, the one from the
input_server, was created. This lead to two AddOnManagers being active
in the input_server which very well could be responsible for #11049
and #11280.
This was a regression since the move of the AddOnManager from the
media_server to libmedia.so in hrev47086. This also fits with the two
tickets.
I actually noticed the problem when debugging the shutdown process of
the input_server, where the destruction of the wrong AddOnManager
caused a deadlock with itself.
The BNetworkRoute class manages a route_entry and the sockaddr's
associated with it. It replaces the direct use of route_entry in the
BNetworkInterface API.
Using route_entry is fragile and inconvenient as it only holds pointers
to the sockaddr's. When getting a list of routes from the kernel, each
route_entry is set up so that its pointers point into the single flat
buffer that is passed around. Creating a copy of the route_entry and
then deleting the flat buffer makes the pointers in the copy stale.
Returning these route entries therefore always lead to a use-after-free
when they were eventually used.
BNetworkRoute also takes over the code and functionallity of getting
routes from RouteSupport. The corresponding method in BNetworkRoster is
replaced by a static method in BNetworkRoute.
Also distinguish between the default route and gateway of an interface.
GetDefaultRoute() now gets the default BNetworkRoute for the interface
while GetDefaultGateway() gets the associated gateway address within
that default route. Adjust network preferences panel to this change.
Note that we currently only seem to have per interface default routes
and not an actual global default route. This was already the case before
these changes and I did not further investigate what this means.
It can be used to get a stack trace of the current thread. Note that
this works by walking frame pointers and will not produce anything
useful if an application is compiled with the frame pointers omitted.
The stack base and end addresses have to be provided as arguments and
are used to check that the frame pointers fall within that range. These
values are thread specific and can be retrieved with get_thread_info().
No other sanity checks (like checking for loops in the linked list) are
done.
This is a simplified rewrite of the stack trace code from the kernel
debugger.
As this code is common to x86 and x86_64 but is not generic across
architectures I introduced x86_common as a directory to put such
sources.
Extend the get_nearest_symbol_at_address() private runtime_loader
export to include imageName and exactMatch arguments.
The imageName holds the SONAME of the image, if available, so cannot
neccessarily be extracted from the image path.
Whether or not there was an exact match, i.e. the symbol with its size
contains the address, is now returned in exactMatch.
When enabled (using heap_debug_dump_allocations_on_exit(true) or
MALLOC_DEBUG=e) this causes a dump of all remaining allocations when
libroot_debug is unloaded. It uses terminate_after to be called as
late as possible.
When combined with alloc stack traces this makes for a nice if a bit
crude leak checker. Note that a lot of allocations usually remain
even at that stage due to statically, lazyly and globally allocated
stuff from the various system libraries where it isn't necessarily
worth the overhead to free them when the program terminates anyway.
The get_stack_trace syscall generates a stack trace using the kernel
debugging facilities and copies the resulting return address array to
the preallocated buffer from userland. It is only possible to get a
stack trace of the current thread.
The lookup_symbol syscall can be used to look up the symbol and image
name corresponding to an address. It can be used to resolve symbols
from a stack trace generated by the get_stack_trace syscall. Only
symbols of the current team can be looked up. Note that this uses
the symbol lookup of the kernel debugger which does not support lookup
of all symbols (static functions are missing for example).
This is meant to be used in situations where more elaborate stack trace
generation, like done in the userland debugging helpers, is not possible
due to constraints.
* Add a BRow default constructor that use font size to compute height.
* Min height size for Title and Row are decoupled.
* The font ratio for Title and Row are decoupled.
* For small font use min height (set to usual 16.0).
* Better baseline formula.
* Fixes#11944.
* So that you know how much already was, and still has to be downloaded.
* Automatic whitespace cleanup.
* The link in FetchFileJob.h did not fetch the correct header under
Haiku anymore (since the addition of the private headers to the
image).
* drop my fdt tests
* we have to call fdt parsing code *after* cpu_init (why?)
* pass fdt pointer to all FDT support calls to avoid confusion
once we get into the kernel land
* look for PL011 compatible uart and use it
* Add some saftey checks to serial putc code to avoid null*
* fdt_node_check_compatible returns 0 on success not 1
* fdt_get_device_reg needs to add the SOC base to the result
* fdt_get_device_reg might need to add the second range cell
instead of reg?
* You can now optionally specify a converter that does the actual
message to settings conversion, and vice versa.
* This allows for more sophisticated and custom conversions.
* Added an extra looperName argument to the private BApplication
constructor that BServer is using.
* This is now used to fix the ugliness that gave the registrar
a different looper name, and even saves a string comparison.
* Move more code into fdt_support
* We now can query FDT registers based on name or alias
* Return addr_t where it makes sense
* Copyright change ok'ed by mmu_man
* Called via arm_mailbox_bcm2835 *and* arm_framebuffer_bcm2835
* This is a bit messy. We really should be getting these
chipset-centric bases from the provided FDT / DTB.
* I can't think of a way to redo this without undoing
work towards FDT.
* The Raspberry pi 2 uses a new SoC which differs slightly
from the Raspberry Pi 1.
* Someday these two board targets could go away when we get
FDT support.
* To while there was some compatibility between
BCM2708 and BCM2805, it makes the BCM2806 changes
more confusing. We don't have any valueable BCM2708
targets.
Implement the todo in Open Target Folder to select the result by sending
Tracker a message with the refs to select.
Add a new kSelect message constant to tracker_private.h to hook into.
Tracker reads in the message and finds the window that the refs are located in,
activates it, then selects the corresponding poses scrolling the pose view
if necessary.
Bump version of Open Target Folder to 1.0.2
Intel changed the PCH interrupt bits between Sandy Bridge and Ivy Bridge
to make space for the 3rd display pipe. Take this into account and check
for the correct bits on the newer devices.
Fixes#11522.
"BToolBar" matches the current convention ("BStatusBar", "BMenuBar", etc.)
I've no idea what I was thinking when I renamed this before...
Also adjust all users of BToolBar (Tracker and ShowImage).
* The default notifier didn't always take the setting into account.
* The mail server was not using the setting from the settings file and
instead waiting for a message that wasn't sent anywhere.
Fixes#10852.
* Use the preferred time source (GetTimeSource) for the node
* Fix node releasing when creating the connection fails
* Add virtual slots and padding
* Refactor _Connect method
