Make sure the compressed/uncompressed heap size and the chunk size
table look plausible, so we can rely on the values later. Fixes
potential crashes for corrupt packages.
* 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().
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".
Block SIGCHLD in all threads and spawn a dedicated thread that handles
the signal in a loop (via sigwait()). This avoids the issue that the
SIGCHLD could be handled in any of our threads and thus possibly
interrupt a syscall.
Fixes#10941.
* The Install() and Update() versions that take a const char* array
now check whether a string looks like a path to a local package file.
If so, they use that file instead of interpreting the string as a
search string.
* Extend the repository hierarchy. There's now a LocalRepository base
class from which InstalledRepository and the new MiscLocalRepository
derive. The latter is instantiated once and collects all package files
specified by path.
* BFatalErrorException: Add commitTransactionResult property and
respective constructor. In case committing the transaction failed,
BPackageManager throws a BFatalErrorException with the result.
* BFatalErrorException::UserInteractionHandler: Pass
BCommitTransactionResult to ProgressTransactionCommitted().
* 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.
Add GetPathOrName() and PathOrName() methods which try to get some kind
of usable path or at least a file name for the entry. Useful mainly for
debugging and error reporting cases.
CommitTransactionHandler: Since the VolumeState is now always copied
(including the contained packages), we can't just use the passed in
packagesAlready{Added,Removed} sets, since they refer to the original
packages.
When a system package is going to be deactivated, activate/deactivate
the packages of the whole transaction only to the latest state.
Afterward latest state and active state will differ.
* VolumeState: Move locking to Volume.
* Package: Pull the file related functionality into new class
PackageFile. A Package refers to a PackageFile. A PackageFile can be
referenced by multiple Packages. PackageFiles are managed by the new
PackageFileManager.
* CommitTransactionHandler: Clone the passed volume state.
* Volume now manages two VolumeStates: A state reflecting the currently
active packages and the latest state (i.e. the one reflecting the
situation of the packages directory). Usually the two are the same,
unless an old state has been booted.
* The client interface hasn't been adjusted yet. Clients only see the
latest state.
* PackageFSVolumeInfo: Add the directories for all relevant states.
* PackageFSPackageInfo: Include the package file's parent directory node
ref.
Package daemon and package kit still don't support old states yet.
If an old state is specified via mount parameters we load the packages
as specified in its activated-packages file.
The interface for the package daemon, the package daemon itself, and
the package kit are still to be adjusted, so ATM some PM components
might be a bit confused when an old state was booted.
For potential boot volumes with older packages states the respective
item in the boot volume menu now has a sub menu for selecting a state.
The boot loader functionality for this feature is complete -- i.e. the
respective kernel is loaded and the name of the old state is added to
the kernel args -- but kernel packagefs and package daemon support is
still missing.
* ... instead of queuing it for the job thread. The advantage is that
the request will be handled immediately and clients won't have to wait
for transactions (which may even require user feedback) to finish. It
complicates Volume a bit, since there are now two threads that may
access it. The shared data have been moved to a State object which is
protected by a lock.
* For commit transaction requests check whether another package request
is already pending/in progress before queuing a job. Fail immediately,
if there is.
Fixes bug #10039.
* The transaction_type(.., ..., SOLVER_TRANSACTION_RPM_ONLY)
categorization of the transaction steps is incorrect since rpm
automatically replaces an older package version when a new one is
installed and thus such package removals would be omitted. Use a
simpler check instead.
* Omit the unnecessary explicit check whether a package really has to be
installed.
Thanks to Michael Schroeder @ SUSE for his help figuring this out.
Instead of 1/10000 we now add 1/128 to the width to compensate for
rounding inaccuracies. Due to the limited float mantissa precision
(23 bit) the previous value would already have no effect for relatively
small widths (>= 128).
Fixes#10455.
Use the new SetIconForType() and SetSupportedTypes() versions and
request the MIME DB not to be updated. This changes the
update_mime_info() and mimeset (without -a/-A) behavior in that they
only modify the (application) file attributes, now. Addresses #10453.
Add SetSupportedTypes() and SetIcon[ForType]() versions with an
additional bool updateMimeDB parameter. If false, the method doesn't
update the MIME DB entries for the type.
