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.
* 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.
* 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.
* Address TODO about setting fSelected when nothing is done.
* Pass a pointer to the tab view to the BTab so that it can call Invalidate().
(Checked against BeOS).
* Call Invalidate() from the BTab after SetView() & SetName().
Fixes#12108 & #12196.
