Besides that this is a nicer interface, it allows us to get a the HPKG
header as a side effect of initializing the reader, thus preventing
seeking backward in the file. This makes "package recompress - <file>"
work.
Until now we always declared in the HPKG header that the package file is
zlib compressed. For uncompressed files we would just store all
individual chunks uncompressed. Now we handle completely uncompressed
files slightly differently: We don't write the redundant chunk size
table anymore. The size savings are minor, but it makes the uncompressed
format read-streamable which may be handy.
* PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and
their implementation and super classes do now internally use a
BPositionIO instead of a FD to access the package file. This provides
more flexibility needed for features to come.
* BPackageReader has already grown a new Init() version with a
BPositionIO* parameter.
Can be requested/stopped via BPackageRoster::{Start,Stop}Watching().
The notification message has the what code B_PACKAGE_UPDATE and contains
fields "event", "location", and "change count".
* BDaemonClient: Move inner class BCommitTransactionResult to top level
and make it public.
* BCommitTransactionResult:
- Add a whole bunch of specific error code enum values. Such an error
code is now the primary error, as opposed to before where we would
mix status_t and enum value errors. There's a systemError property
of type status_t which may provide additional information, though
(depending on the primary error type).
- Remove the errorMessage property. Due to mapping all errors to the
specific error codes this is no longer necessary. Mixing such a
message with another error description is also not very helpful when
it comes to localization (still not supported, though).
- Add several properties (paths, strings, error codes) that serve as
arguments to the primary error and are used by FullErrorMessage().
- Add issues property, a list of instances of new class
BTransactionIssue. Those describe non-critical issues (e.g. failed
update of a settings file) that occurred in the process of
committing the transaction. Those issues should be presented to the
user by the package management program.
* Exception: Adjust to transport the BCommitTransactionResult
properties.
* CommitTransactionHandler, FsTransactions, Root, Volume: Adjust to
BCommitTransactionResult/Exception changes.
* CommitTransactionHandler: Now requires a BCommitTransactionResult to
which it adds the issues it encounters. The reply BMessage is no
longer needed, though.
* Volume: Refactor common code from the three methods that use
CommitTransactionHandler into new method _CommitTransaction.
* This will be used to implement compressed http streams
* Remove the custom BDataOutput class, and use BDataIO instead, for
easier integration with existing code.
* BSolver/LibsolvSolver: Add FullSync() method. It uses libsolv's
SOLVER_DISTUPGRADE mode.
* BPackageManager: Add FullSync() using the new solver mode.
* pkgman: Add full-sync command.
The new command is similar to the update command without arguments, just
more aggressive, allowing downgrading or even removal of packages, to
match the state of the repositories. Just like "update" it doesn't work
properly yet.
* 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.
- 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.
- A subset of jobs that require a BContext don't in fact make use of the
decision provider. As such, make the default implementation usable for
those cases so one doesn't need to always create a dummy derived class.
The property is archived and unarchived, but otherwise not yet stored.
If not set, FileName() returns CanonicalFileName(). Can be used for
packages like haiku.hpkg etc. that don't have a properly qualified file
name (yet).
Only flag ATM is B_VERIFY_ALLOW_UNINSTALL. It tells to solver to suggest
uninstalling packages when necessary instead of considering such a case
a problem.
* Under the base URL there are supposed to be the repository files and a
subdirectory "packages".
* Fix the repository URL related confusion introduced earlier. The URL
in
the repository info (and thus in the repository file) is supposed to
be the base URL for the repository. It is not a (potentially)
different base URL for the package files. Package and repository
files were supposed to live in the same directory. Now, by requiring
the package files to live in a subdirectory -- which can also be a
symlink -- we gain some flexibility.
The URL in the repository config is usually the same as the in the
repository info, unless it refers to a mirror site. This allows for
mirrors to copy the original repository verbatim.
* Remove the PackageURL rule and introduce a DownloadPackage rule
instead. The URL for a package file cannot be computed in the jam
parsing phase anymore, as it contains the hash value of the package
list.
* BRepositoryConfig: Add PackagesURL() for convenience.
* 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.
* 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.
... <package/hpkg/PackageAttributes.h>, which also defines other
properties (name and type) for each attribute. It does so via a macro
that the caller can define to generate whatever code is desired.
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.
* 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.
* 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.
