* 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.
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.
* 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().
* Implement copy-on-write support.
* Add copy constructor and assignment operator.
* Remove Init(). Initialize lazily instead. Since AddInfo() can fail
and we check initialization anyway, there's no point in having an
explicit Init(). Given that there was only one invocation of Init()
in the package kit and its users, it was very likely missing in some
places.
* Fix a few places where we ignored that the PackageMap actually
contains lists of PackageInfo objects.
* It no longer consists of a BPackageResolvableExpression and a
repository. Instead it can now either refer to a package directly or
consist of a search string.
* SolverPackageSpecifierList: Add AppendSpecifier() convenience
versions.
* Adjust LibsolvSolver and pkgman accordingly.
* BSolver/LibsolvSolver:
* Add B_FIND_IN_NAME and make searching in the names explicit.
* Add B_FIND_IN_PROVIDES to search the packages' provides list.
* pkgman: Also search in provides.
* Reorganize things a bit:
- BSolver is now an abstract base class.
- A libsolv based implementation, LibsolvSolver, lives in a new
add-on, which is loaded lazily.
- Get rid of libpackage_solver. Save for LibsolvSolver everything
is moved to libpackage.
- This is a nicer solution for the cyclic dependency caused by
libsolv (libsolvext to be precise) using the package kit for
reading repositories and package files.
* Add a solver result data structure and and an accessor the solver.
* Add problem reporting support to the solver. There aren't data
structures for the problem solutions yet and support for selecting
solutions and re-solving is missing as well.
* BPackageVersion: Add respective constructor and SetTo().
* BPackageInfo: Add static ParseVersionString() utility method. It's
only there because the parser lives in the BPackageInfo
implementation.
* Move StandardErrorOutput to libpackage and into proper namespace to
avoid "package_repo" having to reuse the "package" source file.
* package_repo: Fix incorrect includes of "package.h".
Not functional (or tested) yet. The libsolv setup for a somewhat
simplified installation case should be more or less complete, though.
The solution conversion to to-be-created Haiku data structures and the
handling of problems is still missing, though.
The implementation is temporary. Currently it reads through the packages
in the respective packages directory and checks against the package
links. Once package activation is tracked explicitly we'll use the
activation file/directory.
A BPackageContentHandler subclass that initializes a BPackageInfo from
the read package attributes. Pulled out of RepositoryWriterImpl's
PackageContentHandler.
* Remove InitCheck() and the initializing constructor.
* Rename PackageCount() to CountPackages().
* Use BOpenHashTable instead of HashMap for the internal PackageMap.
* Allow multiple packages with the same name. Equally named packages are
in a singly linked list after the first package with that name.
* Add an Iterator inner class and a GetIterator() method, so one can now
iterate through the packages in the repository.
