* VMAddressSpace: Add randomizingEnabled property.
* VMUserAddressSpace: Randomize addresses only when randomizingEnabled
property is set.
* create_team_arg(): Check, if the team's environment contains
"DISABLE_ASLR=1". Set the team's address space property
randomizingEnabled accordingly in load_image_internal() and
exec_team().
* Create new interface for cpuidle modules (similar to the cpufreq
interface)
* Generic cpuidle module is no longer needed
* Fix and update Intel C-State module
* Increase FIFO buffer capacity from 32 to 64 KiB and the FIFO atomic
write size ({BUF_SIZE}) from 512 bytes to 4 KiB (both like Linux).
* Fix *pathconf(..., _PC_PIPE_BUF). It was returning 4 KiB although the
implemented atomic write size was 512 bytes only. Now both *pathconf()
and the FIFO implementation refer to the same constant.
A DatabaseLocation is passed to the constructor and used to verify that
the sniffed MIME type is installed instead of BMimeType::IsInstalled().
This makes the add-on independent of the default MIME DB.
Most of the hooks don't strictly need a non-empty implementation. The
defaults now simply throw exceptions in those that do. This allows the
class to be instantiated, which is useful when a BPackageManager is only
used for finding packages.
Require the installation interface and the user interaction handle to
be passed to the constructor. Formerly, derived classes set them
manually in their constructors. This makes using the class without
having to subclass it possible.
It's a browser for the system package content, where entries can be
selected to blacklist them. The selected entries are removed from the
packagefs instance in the boot loader, so that e.g. selected drivers
won't be picked up. The paths are also added to the safe mode driver
settings and will be interpreted when the system packagefs instance is
mounted by the kernel.
* Make Menu and MenuItem polymorphic.
* MenuItem:
- Make SetMarked() virtual, so it can be overridden.
- Add SetSubmenu() and Supermenu().
- Delete the submenu in the destructor.
* Menu:
- Add Entered()/Exited() hooks. They frame the time the user navigates
the menu or any of its submenus. The hooks allow for subclasses
populating their item list dynamically.
- Add SortItems().
* Update boot loader menu copyright text to include 2013, now that it is
over soon. :-)
In each installation location, it is now possible to create a settings
file "packages" that allows to blacklist entries contained in packages.
The format is:
Package <package name> {
EntryBlacklist {
<entry path>
...
}
}
...
<package name> is the base name (no version) of the respective package
(e.g. "haiku"), <entry path> is an installation location relative path
(e.g. "add-ons/Translators/FooTranslator").
Blacklisted entries will be ignored by packagefs, i.e. they won't appear
in the file system. This addresses the issue that it may be necessary to
remove a problematic file (e.g. driver, add-on, or library), which would
otherwise require editing the containing package file.
The settings file is not not "live". Changes take effect only after
reboot (respectively when remounting the concerned packagefs volume).
* get_architectures() returns the primary and the secondary
architectures in one array. That turned out to be convenient.
* Add C++ versions for get[_secondary]_architectures(), returning a
BStringList.
* Add get_architecture(), get_primary_architecture(),
get_secondary_architectures(), guess_architecture_for_path() to get
the caller's architecture, the primary architecture, all secondary
architectures, or the architecture associated with a specified path
respectively.
* Rename the find_path*() functions to find_path*_etc() and add an
optional architecture parameter. Add simplified find_path*()
functions.
* BPathFinder: Add FindPath[s]() versions with an architecture
parameter.
By passing the window pointer to ScreenSaverRunner contructor and using that
to lock the window when drawing instead of getting the window from the
Window() method of the view. This is safer.
Start the screensaver in the window thread instead of the runner
thread so that there is no lock contention for the window lock in
the runner thread when the saver starts.
The view that gets drawn into is assumed to have been prepared before
being passed to the runner thread, and this assumption has been made
true for the screensaver preview and screen_blanker apps.
Eliminate fHasStarted and the corresponding HasStarted() method in
ScreenSaverRunner as they are no longer needed.
Drawing still happens in the runner thread, and still needs to lock
the window thread potentially causing contention, yet, there
is a timeout here so the contention won't freeze the screensaver window,
only delay drawing the screensaver.
Drawing could be moved to the window thread via message passing to avoid
lock contention with the window but this would defeat a big part of the
purpose of having a separate rendering thread.
This fixes #10125 and #4260
* pin idle threads to their specific CPUs
* allow scheduler to implement SMP_MSG_RESCHEDULE handler
* scheduler_set_thread_priority() reworked
* at reschedule: enqueue old thread after dequeueing the new one
* Thread::scheduler_lock protects thread state, priority, etc.
* sThreadCreationLock protects thread creation and removal and list of
threads in team.
* Team::signal_lock and Team::time_lock protect list of threads in team
as well.
* Scheduler uses its own internal locking.
