* 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 is no longer public (or even private) API. BPackageDataReaderFactory
returns a BAbstractBufferedDataReader instead. The advantage is that
the latter doesn't have hpkg format specific dependencies.
It doesn't do much in terms of buffering, but defines an interface
buffered readers can implement, namely the additional
ReadDataToOutput() which currently BPackageDataReader specifies.
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.
... back to their previous void returning roles. AlertPosition() is used instead to
check that an alert fits within the sides of the screen and all that.
Also add another CenterOnScreen() method that takes a Screen ID
so you can center a window on another monitor that the one it is currently on
(theoretically someday anyway).
...to position alert's and open/save dialogs nicely inside of the parent window,
or if that is unavailable, the screen frame.
AlertPosition() is private (for now) but BAlert and BFilePanel are BWindow's friends so
BWindow allows those classes to touch it's privates.
* These methods now return the new point after centering.
* But more importantly CenterIn() does some new adjustments to keep the window
position inside the screen edge. If you pass the screen frame into CenterIn()
it skips these adjustments.
The name of the package file is not part of the package-info.
CanonicalFileName() constructs the name the file should have (not
enforced anywhere (yet)).
* ... to avoid confusion with the preRelease property. It's also called
"revision" in the HaikuPorts recipes.
* Update libsolv package. Was necessary due to the BPackageVersion
change, but also includes a few more changes.
In sake of consistency with other Windows CP encodings:
* print_name is expanded to "Windows Central European (CP 1250)";
* B_MS_WINDOWS_1250_CONVERSION id looks like should be added into UTF8.h;
* mime_name set to NULL as other windows codepages have. That prevents
at least from duplicating too much 1250's in the Terminal, Mail and
StyledEdit encodings menus.
* Rename PackageDaemonDefs.h to DaemonDefs.h.
* Replace the MESSAGE_GET_PACKAGES by the new
B_MESSAGE_GET_INSTALLATION_LOCATION_INFO, which not only returns the
packages, but also other information about the installation location.
* daemon: Volume: Implement a change count which is bumped whenever
packages are activated/deactivated/added/removed. Cache the reply
for a location info request, using the change count to check whether
it is still up-to-date.
* Add private BDaemonClient for communication with the daemon.
* BRoster:
- Add GetInstallationLocationInfo() using BDaemonClient.
- Reimplement GetActivePackages(), using
GetInstallationLocationInfo().
