Simple BPositionIO implementation using the POSIX API on a FD. In effect
similar to BFile, but more easily ported to kernel and boot loader (and
the FD is reusable).
* BCompressionAlgorithm is a base class for classes that provide
compression/decompression functionality. There are methods for
compressing/decompressing a single buffer and factory methods for
a compressing/decompressing input/output BDataIO.
* BZlibCompressionAlgorithm is a BCompressionAlgorithm implementation
using zlib.
* FDDataWriter and ZlibDataWriter weren't used anymore.
* AbstractDataWriter was implemented only by PackageFileHeapWriter,
which was only used by WriterImplBase.
* Add a PackageFileHeapWriter::AddDataThrows() which has semantics
equivalent to the previously inherited WriteDataThrows().
* Instead of forcing the hash-table to use a copy of the key,
introduce and use TypeOperation template to avoid taking a
reference of a reference type (which gcc2 doesn't allow).
* This will be used to implement compressed http streams
* Remove the custom BDataOutput class, and use BDataIO instead, for
easier integration with existing code.
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.
* 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.
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.
* 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.
* This pulls in some more stuff, like libicon and agg which are also
included in libbe_build, now.
* Update a few libbe_build classes and headers needed to get things
building.
* This likely breaks the <build>mimeset build on Haiku.
* daemon: Handle new request B_MESSAGE_COMMIT_TRANSACTION. It activates
and deactivates given sets of packages. The new packages must be
placed in a directory in the administrative directory. The daemon
moves them to the packages directory and the deactivated packages to
a subdirectory it creates. It also save the old activation state
there.
* Add private BActivationTransaction, describing an activation change
transaction.
* BDaemonClient: Add CommitTransaction(), which sends a given
BActivationTransaction as a B_MESSAGE_COMMIT_TRANSACTION request to
the daemon.
Completely untested yet.
Apparently I should have done a complete rebuild after moving
directories.h from headers/private/libroot to .../system, since a lot of
stuff didn't build anymore.
* libbe_build: Where possible we directly use the actual Haiku headers and
sources, now. In the headers/build headers we just include the respective
Haiku headers as needed. That still allows overrides where necessary. The
intention is to make it easier to keep the build stuff in sync.
* Fixed a few printf() format and signed/unsigned comparison warnings.

* the libbe_build version of BString was broken, at least with respect
to LockBuffer() on an empty string - replaced the implementation and
header with our current version (keeping the type-related changes
required by the build-version)

of BKeymap was not compatible with IsDeadKey() of the other Keymap
incarnations.
* Now, I've renamed IsDeadKey() to DeadKey(), and introduced a new
ActiveDeadKey() method that works like the other former IsDeadKey().
* This fixes the dead key problems my earlier BKeymap work introduced.

* Implemented BGradient, BGradientLinear, BGradientRadial,
BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.
* Implemented all the (AGG-based) backend necessary in
the app_server to render gradients (Painter, DrawingEngine)
* app_server/View can convert a BGradient layout to screen
coordinates.
* Added BGradient methods of the Fill* methods in BView.
* Implemented a test app and added it to the image as a
demo.
* Adopted Icon-O-Matic and libs/icon in order to avoid
clashing with the new BGradient class. Re-use some
parts where possible.
Awesome work, Artur! Thanks a lot. Now a more modern
looking GUI has just become much easier to implement! :-)
TODO:
* Remove the need to have gradient type twice in the
app_server protocol.
* Refactor some parts of the patch to remove duplicated
code (Painter, DrawingEngine).
* Adopt the BPicture protocol to know about BGradients.
* Review some parts of the BArchivable implementation.

of the resolved ToDo, but could probably be made more efficient. Instead of
transfering the area, the area is cloned into the target teams' address space
and the original is deleted. This generates a new area_id for the transfered
area (as suggested by the ToDo). Updated syscall prototypes according to the
status_t to area_id return type change.

* Also ported over the new MessageAdapter class
* Removed old BMessage implementation prototypes that apparently were left in the private folder
