* VMTranslationMap:
- Add DebugPrintMappingInfo(): Given a virtual address it is supposed
to print the paging structure information for that address. To be
implemented by derived classes.
- Add DebugGetReverseMappingInfo(): Given a physical addresss it is
supposed to find all virtual addresses mapped to it. To be
implemented by derived classes.
* X86VMTranslationMapPAE: Implement the new methods
DebugPrintMappingInfo() and DebugGetReverseMappingInfo().
* Add KDL command "mapping". It supports both virtual address lookups
and reverse lookups.
__flatten_process_args() does now have the executable path as an
additional (optional) parameter. If specified, the function will read
the file's SYS:ENV attribute (if set) and use its value to modified the
environment it is preparing for the new process. Currently supported
attribute values are strings consisting of "<var>=<value>" substrings
separated by "\0" (backslash zero), with '\' being used as an escape
character. The environment will be altered to contain the specified
"<var>=<value>" elements, replacing a preexisting <var> element (if
any).
A possible use case would be setting a SYS:ENV attribute with value
"DISABLE_ASLR=1" on an executable that needs ASLR disabled.
* 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.
* The UNMAP command is theoretically much faster, as it can get many block
ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
to trim.
* Updated BFS code to collect array ranges to fully support the new
fs_trim_data possibilities.
* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.
The new functions are meant to replace many uses of find_directory():
* find_paths() is supposed to be used when the directories of a certain
kind in all installation directories are needed (e.g. font
directories, add-on directory, etc.). Using this API makes code
robust wrt addition or removal of installation locations.
* find_path() is supposed to be used when files/directories associated
with a loaded program, library, or add-on need to be found (e.g. data
files or global settings).
* find_path_for_path() is similar to find_path(), but it starts from a
given path instead of an image.
The flag main purpose is to avoid race conditions between event handler
and cancel_timer(). However, cancel_timer() is safe even without
using gSchedulerLock.
If the event is scheduled to happen on other CPU than the CPU that
invokes cancel_timer() then cancel_timer() either disables the event
before its handler starts executing or waits until the event handler
is done.
If the event is scheduled on the same CPU that calls cancel_timer()
then, since cancel_timer() disables interrupts, the event is either
executed before cancel_timer() or when the timer interrupt handler
starts running the event is already disabled.
* Replace ports list mutex with R/W-lock.
* Move team port list protection to separate array of mutexes.
Relieve contention on sPortsLock by removing Team::port_list from its
protected items. With this, set_port_owner() only needs to acquire the
sPortsLock for reading.
* Add another hash table holding the ports by name. Used by find_port()
so it doesn't have to iterate over the list anymore.
* Use slab-based memory allocator for port messages. sPortQuotaLock was
acquired on every message send or receive and was thus another point
of contention. The lock is not necessary anymore.
* Lock for port hashes and Port::lock are no longer locked in a nested
fashion to reduce chances of blocking other threads.
* Make operations concurrency-safe by adding an atomically accessed
Port::state which provides linearization points to port creation and
deletion. Both operations are now divided into logical and physical
parts, the logical part just updating the state and the physical part
adding/remove it to/from the port hash and team port list.
* set_port_owner() is the only remaining function which still locks
Port::lock and one or two of sTeamListLock[] in a nested fashion.
Since it needs to move the port from one team list to another and
change Port::owner, there's no way around.
* Ports are now reference counted to make accesses to already-deleted
ports safe.
* Should fix#8007.
When removing a string attribute, decrement the referenced string's
usage count in the string cache. This fixes the potentially incorrect
usage counts in update mode. Not a serious problem, but it could lead
to only singly (or no longer) used strings to be written to the string
subsection instead of encoding them inline and thus to slightly greater
file sizes.
When joining with a single range, firstRange would be the same as
RangeAt(endIndex - 1) and we would overwrite its offset field before
getting its end offset, thus possibly resulting in a wrong joined range
size.
Simple scheduler behaves exactly the same as affine scheduler with a
single core. Obviously, affine scheduler is more complicated thus
introduces greater overhead but quite a lot of multicore logic has been
disabled on single core systems in the previous commit.
The method is supposed to return B_OK as long as the _result object has
been initialized, even if committing the transaction failed. Fixes the
unhelpful error messages of pkgman when committing the transaction
failed for some reason.
Update BKeymap::GetModifiedCharacters() to translate a given character
and set of modifiers filling out a list of all characters that match for another
set of modifiers.
This allows us to, for example, get all characters in the normal map that
have the '+' character in the corresponding shift map.
It is fully generic allowing one to get a list of characters in any map given
a character and modifiers of another map.
Also I converted from using a BList to using a BObjectList.
With this, along with BWindow::HasShortcut(), the semantic shortcuts now
work not only with Command+'=', but any key in the normal map that has
'+' in it's shift map as long as it isn't already taken by another shortcut.
This method fills out the passed-in BList of modified utf-8 characters for
a given utf-8 character and set of modifiers.
For example if you pass in "=" and B_SHIFT_KEY the list will get filled
out with each character in the shift map that has "=" in the normal map.
Each supported keymap modifier combination is available.
The reason this is useful will soon become apparent.
A BList is used because the character might be mapped multiple times,
for example if you have a Mac keyboard you've got two "=" keys, one in
0x1d and one in 0x6a.
The caller is responsible for creating the BList and destroying it as well as
freeing the resulting character strings.
This builds off of hrev46243 adding add-on directories all in one place
in AddOnMonitorHandler instead of repeating the code 3 times in
IndexServer, AddOnManager, and MediaAddOnServer.
The safe mode checking in InputServer is now redundant since it all
gets funneled into AddOnMonitorHandler::AddAddOnDirectories()
and the safe mode flags are checked there.
We should probably remove the InputServer::SafeMode() method, but,
I didn't want to break anything that depended on it so I left it.
There is a global heap of cores, where the key is the highest priority
of threads running on that core. Moreover, for each core there is
a heap of logical processors on this core where the key is the priority
of currently running thread.
The per-core heap is used for load balancing among logical processors
on that core. The global heap is used in initial decision where to put
the thread (note that the algorithm that makes this decision is not
complete yet).
Simple scheduler is used when we do not have to worry about cache affinity
(i.e. single core with or without SMT, multicore with all cache levels
shared).
When we replace gSchedulerLock with more fine grained locking affine
scheduler should also be chosen when logical CPU count is high (regardless
of cache).
In SMP systems simple scheduler will be used only when all logical
processors share all levels of cache and the number of CPUs is low.
In such systems we do not have to care about cache affinity and
the contention on the lock protecting shared run queue is low. Single
run queue makes load balancing very simple.
Kernel support for yielding to all (including lower priority) threads
has been removed. POSIX sched_yield() remains unchanged.
If a thread really needs to yield to everyone it can reduce its priority
to the lowest possible and then yield (it will then need to manually
return to its prvious priority upon continuing).
Each thread has its minimal priority that depends on the static priority.
However, it is still able to starve threads with even lower priority
(e.g. CPU bound threads with lower static priority). To prevent this
another penalty is introduced. When the minimal priority is reached
penalty (count mod minimal_priority) is added, where count is the number
of time slices since the thread reached its minimal priority. This prevents
starvation of lower priorirt threads (since all CPU bound threads may have
their priority temporaily reduced to 1) but preserves relation between
static priorities - when there are two CPU bound threads the one with
higher static priority would get more CPU time.
Should already have been done back when the semantics for the
B_COMMON_*DIRECTORY constants was changed.
Currently old and new version behave the same. So this is just a
contingency measure ATM.
* This does intentionally break source compatibility, so that a review
of concerned code is forced.
* Binary compatibility should be maintained in most cases. The values
of the constants for the writable directories are now used for the
writable system directories. The values for the non-writable
directories are mapped to "/boot/system/data/empty/...", an empty or
non-existent directory, so that they will simply be skipped in search
paths. Only code that explicitly expects to find something in a
B_COMMON_* directory, will fail.
* Remove support for the "common" installation location from packagefs,
package kit, package daemon, package managers.
* Rename the B_COMMON_*_DIRECTORY constants referring to writable
directories to B_SYSTEM_*_DIRECTORY.
* Remove/adjust the use of various B_COMMON_*_DIRECTORY constants.
I'm sure some occurrence still remain. They can be adjusted when the
remaining B_COMMON_*_DIRECTORY constants are removed.
* find_directory() and hard-coded paths use /boot/system instead of
/boot/common.
* The build system creates the writable directories in /boot/system
instead of /boot/common.
* The build system no longer installs any packages in /boot/common.
* The new class is called DriverSettingsMessageAdapter which can translate
between a driver_settings file, and a BMessage.
* The net_server Settings class is now just using this class.
- BJobStateListener: Add progress state and corresponding hook.
- FetchFileJob: Notify job progress hook on libcurl notifications.
- UserInteractionHandler: Add hooks for download progress and checksum
validation progress.
- PackageManager: inherit from JobStateListener and watch for job
notifications for internally generated jobs. Forward to corresponding
UserInteractionHandler hooks as needed.
- Adapt pkgman, HaikuDepot and package_daemon to above changes.
Neither HaikuDepot nor package_daemon's progress hooks are wired up to
do anything yet though.
- Pull functionality back into package manager itself since the extra
indirection doesn't really buy us anything in this case, as neither
request that it handles requires a decision provider.
- Adjust pkgman and HaikuDepot accordingly.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
* Add NotifyDone() to all repository-attribute handlers and invoke that
to notify any listeners.
* Unify deletion to a single implementation of Delete() in the base
class. Before, the root handler for a repository didn't do that, but
just triggered the notification.
Support for 64-bit atomic operations for ARMv7+ is currently stubbed
out in libroot, but our current targets do not use it anyway.
We now select atomics-as-syscalls automatically based on the ARM
architecture we're building for. The intent is to do away with
most of the board specifics (at the very least on the kernel side)
and just specify the lowest ARMvX version you want to build for.
This will give flexibility in being able to distribute a single
image for a wide range of devices, and building a tuned system
for one specific core type.
This adds the -mapcs-frame compiler flag for ARM to have "stable"
stack frames, adds support to the kernel for dumping stack crawls,
and initial support for iframes. There' much more functionality
to unlock in KDL, but this makes debugging already a lot more
comfortable.....
Since both platforms can boot the same kernel we must accept either
arg, so we make sure they are identical for now.
TODO: use a union or KMessage maybe?
As korli suggested use B_PAGE_SIZE for defining stack size related
definitions what seems to be more natural for them and also may
help if we ever support an architecture with page size different than
4kB.
* Seems like there was no easy way to simply invalidate
a given BRow. Introduced BColumnListView::InvalidateRow().
* BRow::SetField() tried to invalidate the row, but invalidated
the listview instead of the BOutlineView responsible for
drawing the list contents. Use the new InvaalidateRow().

* It simplifies putting regular layout-aware views or layout items into
a BScrollView.
* Not quite complete yet: Height-for-width support is missing, but that
also requires fixing BScrollView in this respect. Scroll bar auto-hide
support would be nice as well.
* Rename TransactionHandler -> InstallationInterface and
DaemonClientTransactionHandler -> ClientInstallationInterface.
* Add InstallationInterface::InitInstalledRepository(). Use in
_AddInstalledRepository() to get the repository packages instead of
using the package roster. The ClientInstallationInterface
implementation does it that way.
If we fail to lock the window in the kInitialTickRate time, quit the thread.
We were deadlocking causing #4260 because you could open several
threads by moving through the screen saver list quickly all trying to lock
the same window at the same time, classic deadlock.
* Move RepositoryBuilder class to libpackage and add B* prefix to name.
* Pull BPackageManager class out of PackageManager and move to
libpackage. The base class is customizable via three handler objects
responsible for transaction handling, request execution, respectively
user interaction.
* Reorganize _ApplyPackageChanges(): Now we first prepare the
transactions for all affected installation locations (downloading
files etc.) and then commit them.
* The default module is replaced by the Virtio RNG module when found.
* This can have the undesired effect of rendering /dev/urandom slow.
* Tested with the following QEmu command line option:
-device virtio-rng-pci,rng=rng0 -object rng-random,filename=/dev/random,id=rng0
* moved random.h to private/drivers headers.
It provides the functionality to copy file system entries (also
recursively). The code originates from the copyattr sources. Some
copyattr specific functionality has been removed and the code has been
adjusted for library use (i.e. no exit()s or fprintf()s). An optional
controller object can be set to customize the behavior.
* Mostly useful for virtualization at the moment. Works in QEmu.
* Can be enabled by safemode settings/menu.
* Please note that x2APIC normally requires use of VT-d interrupt remapping feature
on real hardware, which we don't support yet.
Get rid of unused fRunner variable.
It is very basic now, it just works.
Also, renamed msg to message in MessageReceived() and
declared MakeFocus() above it (alphabetically).
the child menu bar or the child menu bar's menu is enabled/disabled.
This means that there is just one status we have to check, the menu
fields, and the child menus agree. This change takes practical form
in the Backgrounds preflet which disables the placement menu when
the image is set to "None", but, only the menu got disabled and not the
parent menu field so the label was erroneously still drawn as enabled.
* the processing of requests in drivers is eased a bit with this change, but
this could be improved for instance by enabling a driver to dequeue items
in a service thread instead of the interrupt handler.
* made a few methods const.
* make use of MSI/MSI-X PCI x86 API
* MSI support untested because QEmu only offers MSI-X
* changed a bit the Virtio bus API by adding a queue count parameter
for the setup_interrupt() hook.
* They are all over the place.. I give up
* Going off of engineering names and DCE is more accurate
* A lot of this info came from the x.org wiki
* I'd like to transition some of the engineering
name checks to use DCE versions.. they tend to be more
accurate and exact. (in some cases we can't, but most of
the time we can)
* Introduce new package attribute B_HPKG_ATTRIBUTE_ID_PACKAGE (valid
only in a repository file) to group the attributes belonging to a
package.
* BRepositoryContentHandler:
- No longer derive from BPackageContentHandler.
- Add hooks HandlePackage() and HandlePackageDone() that bracket the
attributes for a package. This is more explicit and robust than
handlers having to guess when one package ended and the next began.
* BRepositoryCache: Make use of BPackageInfoContentHandler. No need to
duplicate the code for reading a package info from package info
attributes.
This resolves all issues the test suite uncovered. It should also deal
with hard links correctly, though that hasn't been tested. Still
unsupported are:
* changes due to mounting/unmounting a volume,
* tracking of symlinks in the path components.
Add inner class BWatchingInterface and method SetWatchingInterface().
This abstracts the calls to watch_node() and stop_watching(), thus
making it possible to use the path monitor in Tracker.
Fixes#9816
It is no longer necessary, or even desirable for us to set the max
content width of the menu bar of a BMenuField now that BMenuItem
truncation and BMenuField sizing are working.
The user may, however, wish to set the max content width of the menu
bar of a BMenuField themselves like so:
menuField->MenuBar()->SetMaxContentWidth(width);
and the Interface Kit will automatically deduct the left and right
margins from the width including the space used by the drop down arrow.
* For all identifiers: Rename global settings file to global writable
file. We want to use the respective attribute also for other writable
files, not only settings files.
* User settings file/global writable file info/attribute: Add
isDirectory property/child attribute. This allows declaring global/
user settings directories associated with the package.
... cancelling the normal item truncation behavior.
This funcationality comes from BeOS R5, we need to reproduce it for
backwards compat. KeymapSwitcher depends on it at least.
Minimum width is 20px, was set in last commit, comes from BeOS R5.
We use these constants in both MenuField.cpp and BMCPrivate.cpp
Incorporate kMarginWidth into kPopUpIndicatorWidth.
A small code simplication in FrameResized() along with replacing bare numbers
with magic constants.
* the Virtio PCI bus driver exposes a Virtio controller to the Virtio bus manager,
which in turn exposes a Virtio device consumed by Virtio drivers. Drivers follow the
new driver model.
* virtio_block handles Virtio block devices under disk/virtual/virtio_block/x/raw.
* Here is the Qemu command line option for Virtio disk devices:
-drive file=haiku.image,if=virtio
* the PCI bus driver currently supports only legacy interrupts (no MSI(-X) yet).
* There is room for improvements in the bus manager:
- it notifies the host for each queued request, which isn't optimal.
- transfer descriptors should probably be simply preallocated (they are nicely
leaked at the moment).
- indirect descriptors are not supported yet.
and in the block driver:
- get the id of the disk.
- implements flushing the cache.
- improves dma restrictions.
- do_io() should use a page for header descriptors instead of malloc(), which
could cross boundaries.
* The device manager tries to guess the driver based on the PCI device type, this
implies having to declare the "busses/virtio" path for each possible type
provided by Virtio. Thus future driver additions might require patching the device
manager.
* virtio.h is still private, the API is subject to changes.
* virtio_pci.h, virtio_blk.h, virtio_ring.h are copied unchanged from FreeBSD.
... the one expected for the respective attribute. Before it was
possible that e.g. a uint was read and then interpreted as a
const char*, if a string was expected for that attribute.
Global and user settings files can be declared. For global ones an
update policy can be specified. If not specified, the settings file is
not included in the package, but created by the program (or user) later.
If an update type is specified, it defines what to do with the settings
file when updating the package to a newer version.
User settings files are never included in the package; they are always
created by the program or the user. If the package contains a template/
default settings file, it can be declared, but for informative purposes
only.
* Add minor_version to hpkg_header and hpkg_repo_header and make
heap_compression uint16.
* If the minor version of a package/repository file is greater than the
current one unknown attributes are ignored without error. This allows
introducing new harmless attributes without making the resulting files
unreadable for older package kit versions.
* ReaderImplBase:
- Add virtual CreateCachedHeapReader() which can create a cached
reader based on the given heap reader.
- Rename HeapReader() to RawHeapReader() and add HeapReader() for the
cached heap reader.
- Add DetachHeapReader() to allow a clients to remove the heap
reader(s) after deleting the ReaderImplBase object.
* packagefs:
- Add CachedDataReader class, which wraps a given
BAbstractBufferedDataReader and provides caching for it using a
VMCache. The implementation is based on the IOCache implementation.
- Use CachedDataReader to wrap the heap reader. For file data that
means they are cached twice -- in the heap reader cache and in the
file cache -- but due to the heap reader using a VMCache as well,
the pages will be recycled automatically anyway. For attribute data
the cache should be very helpful, since they weren't cached at all
before.
* Add flags parameter to Init() of BPackageReader and friends.
* Introduce flag B_HPKG_READER_DONT_PRINT_VERSION_MISMATCH_MESSAGE and
don't print a version mismatch error when given.
* package extract/list: Use the new flag.
* Pull _UnwriteLastPartialChunk() out of Reinit() for reuse.
* _UnwriteLastPartialChunk(): fPendingDataSize wasn't set.
* _PushChunks(): Some simplifications for clarity.
* ChunkBuffer/RemoveDataRanges(): Use data reading and decompression
methods provided by our base class instead of duplicating the
implementation.
* RemoveDataRanges():
- _FlushPendingData() before starting, so we don't ignore the pending
data and _UnwriteLastPartialChunk() when done, so a partial chunk
is read back into the pending data buffer.
- fUncompressedHeapSize wasn't reset before the main processing loop,
thus resulting in an erroneous size later on.
* Introduce BPackageWriterParameters which comprises all parameters
for package creation, currently flags and compression level. Such an
object can be passed to BPackageWriter::Init() and is passed on to
PackageWriterImpl and WriterImplBase.
* PackageFileHeapWriter: Add compressionLevel property and pass the
value on to ZlibCompressor.
* package add/create: Add options -0 ... -9 to specify the compression
level to be used.
Instead of handling compression for individual file/attribute data we
do now compress the whole heap where they are stored. This
significantly improves compression ratios. We still divide the
uncompressed data into 64 KiB chunks and use a chunk offset array for
the compressed chunks to allow for quick random access without too much
overhead. The tradeoff is a limited possible compression ratio -- i.e.
we won't be as good as tar.gz (though surprisingly with my test
archives we did better than zip).
The other package file sections (package attributes and TOC) are no
longer compressed individually. Their uncompressed data are simply
pushed onto the heap where the usual compression strategy applies. To
simplify things the repository format has been changed in the same
manner although it doesn't otherwise use the heap, since it only stores
meta data.
Due to the data compression having been exposed in public and private
API, this change touches a lot of package kit using code, including
packagefs and the boot loader packagefs support. The latter two haven't
been tested yet. Moreover packagefs needs a new kind of cache so we
avoid re-reading the same heap chunk for two different data items it
contains.
It uses sub-namespace BPackage::BHPKG::V1. Unlike the one for the
current format version, the V1 version of BPackageInfoContentHandler
lives in BHPKG(::V1) sub-namespace and is private.
* Use enums/constants/functions instead of preprocessor macros.
* Missing include in PackageInfoAttributeValue.h.
* PackageReaderImpl::Init(): Check version before header size and
return B_MISMATCHED_VALUES instead of B_BAD_DATA, if the version
doesn't match. This allows callers to determine the condition and
try a reader for a different version. A more flexible interface for
that case would be nice, but since we want to support the old package
version only temporarily, the current solution should be good enough.
* If at least one image is either B_HAIKU_ABI_GCC_2_ANCIENT or
B_HAIKU_ABI_GCC_2_BEOS almost all areas are marked as executable.
* B_EXECUTE_AREA and B_STACK_AREA are made public. The former is enforced since
the introduction of DEP and apps need it to correctly set area protection.
The latter is currently needed only to recognize stack areas and fix their
protection in compatibility mode, but may also be useful if an app wants
to use sigaltstack from POSIX API.
* Factor out the code to add some data to the about window, with a header and a content under it
* Make this method public so it's possible to add custom entries in an about box
* If the method is called with only the header or only the content, the text is added non-bold and non-indented (like the description entry*).
* Make the header text bold. I'm not sure it looks that good, after all. Thoughts ?
* Pull out base class MimeEntryProcessor out of AppMetaMimeCreator.
* Pull class MimeInfoUpdater out of UpdateMimeInfoThread and derive it
from MimeEntryProcessor.
* MimeInfoUpdater: Instead of BMimeType::GuessMimeType(), use
Database::GuessMimeType() directly.
* Add class DatabaseLocation. It contains a list of the MIME DB
directory paths plus methods to access type files.
* Move all low-level MIME DB access functions from
database_{support,access} to DatabaseLocation. All code that formerly
used those now requires a DatabaseLocation object. In BMimeType and in
the registrar the default object is used, but the low-level classes
can now be reused with different locations.
* Move get_icon_data() from database_access to database_support and
delete the former, which is now empty.
* Together with database_{access,support}.cpp it is built into a static
library.
* Add new interfaces MimeSniffer and Database::NotificationListener for
plugging in registrar specific functionality (the sniffer add-on
support and the notification mechanism).
Each installation location (system, common, common/non-packaged,
~/config, ~/config/non-package) can now have a read-only data/mime_db
directory. ~/config/settings/beos_mime is now named mime_db as well. The
contents of all directories makes up the MIME DB. Entries in more
specific locations shadow entries in more general locations. Only the
directory in ~/config/settings is where the registrar writes changes to.
The new layout allows packages to contribute entries to the MIME DB by
simply providing the respective files in data/mime_db. Consequently the
user settings directory is supposed to contain only the things the user
has actually changed.
Seems to work fine as far as tested. A few issues, though:
* The registrar doesn't monitor the directories yet, so it doesn't
notice entry changes due to package de-/activation.
* ATM it is not possible to remove a MIME type that is not in the user
settings directory, although the FileTypes GUI suggests that it is.
We'd have to work with white-outs, since we cannot remove the files in
the data/mime_db directories. Or, alternatively, the API has to be
extended and the FileTypes GUI adjusted to disable the "Remove" button
in such a case.
An arbitrary number of directories can be added, which the implemented
BEntryList interface presents as a single merged entry list. Three
different merge policies are supported which define how entries that
appear in more than one directory are treated.
Remove no longer needed header includes, most that I recently added
a few that were already there but just aren't needed anymore. Don't
use BPrivate::MenuPrivate namespace.
Just a few commits ago I moved the label truncation code out of
BMenuItem and into BMCMenuBar because the truncation had to happen
outside of BMenuItem. Turns out, that wasn't true so I'm moving the
label truncation back into BMenuItem and removing the _DrawItems()
method from BMCMenuBar.
Note that the code is not a copy of what was there before, but, the
updated version I created for BMCMenuBar. The main difference is that
I use menuPrivate.Padding() instead of GetItemMargins() and I always
use the width of the parent menu frame instead of using fBounds even
if the state is not MENU_STATE_CLOSED. These are changes needed for
BMCMenuBar but should work just as well for a regular BMenu.
