* get_file_attribute(): Use O_NOTRAVERSE, so we correctly read the
attribute from symlinks.
* internal_path_for_path(): Shuffle things around a bit: The dependency
is resolved before handling B_FIND_PATH_PACKAGE_PATH, now. This adds
support for getting the package file for a dependency. The dependency
was ignored in this case before.
* Use kSystemPackageLinksDirectory instead of hard-coding "/packages".
* Remove possibility to temporarily disable small task packing.
* When small task packing target gets overloaded continue packing
threads on another core, but avoid migrating the already packed
ones.
Scheduler still tends to needlessly migrate threads to another cores
when under heavier load, but it is now much better than before.
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).
* Move PathBuffer helper class out of find_paths.cpp into its own
header.
* find_directory():
- Make use of MemoryDeleter to simplify things.
- Make use of PathBuffer for a simpler and more correct handling.
- Make B_UTILITIES_DIRECTORY to B_APPS_DIRECTORY. /boot/utilities
doesn't exist anyway.
- Resolve the concerned constants to the architecture specific
subdirectory, when called in a secondary architecture context, just
like find_path*().
* 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.
* 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
In case something went wrong, call unlock_memory_etc() with the rounded
base address instead of with the original address. If the original
address wasn't page aligned, unlock_memory_etc() would otherwise try to
unlock an additional page.
