Instances

(GObject o, IsDescendantOf Sysroot o) => IsSysroot o

Defined in GI.OSTree.Objects.Sysroot

toSysroot :: (MonadIO m, IsSysroot o) => o -> m Sysroot

Cast to Sysroot, for types for which this is known to be safe. For general casts, use castTo.

noSysroot :: Maybe Sysroot

A convenience alias for Nothing :: Maybe Sysroot.

Methods

cleanup

sysrootCleanup

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

self: Sysroot

-> Maybe b

cancellable: Cancellable

-> m ()

(Can throw GError)

Delete any state that resulted from a partially completed transaction, such as incomplete deployments.

cleanupPruneRepo

sysrootCleanupPruneRepo

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

sysroot: Sysroot

-> RepoPruneOptions

options: Flags controlling pruning

-> Maybe b

cancellable: Cancellable

-> m (Int32, Int32, Word64)

(Can throw GError)

Prune the system repository. This is a thin wrapper around repoPruneFromReachable; the primary addition is that this function automatically gathers all deployed commits into the reachable set.

You generally want to at least set the OSTREE_REPO_PRUNE_FLAGS_REFS_ONLY flag in options. A commit traversal depth of 0 is assumed.

Locking: exclusive

Since: 2018.6

deployTree

sysrootDeployTree

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

self: Sysroot

-> Maybe Text

osname: osname to use for merge deployment

-> Text

revision: Checksum to add

-> Maybe KeyFile

origin: Origin to use for upgrades

-> Maybe b

providedMergeDeployment: Use this deployment for merge path

-> Maybe [Text]

overrideKernelArgv: Use these as kernel arguments; if Nothing, inherit options from provided_merge_deployment

-> Maybe c

cancellable: Cancellable

-> m Deployment

(Can throw GError)

Check out deployment tree with revision revision, performing a 3 way merge with providedMergeDeployment for configuration.

While this API is not deprecated, you most likely want to use the sysrootStageTree API.

deploymentSetKargs

sysrootDeploymentSetKargs

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

self: Sysroot

-> b

deployment: A deployment

-> [Text]

newKargs: Replace deployment's kernel arguments

-> Maybe c

cancellable: Cancellable

-> m ()

(Can throw GError)

Entirely replace the kernel arguments of deployment with the values in newKargs.

deploymentSetMutable

sysrootDeploymentSetMutable

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

self: Sysroot

-> b

deployment: A deployment

-> Bool

isMutable: Whether or not deployment's files can be changed

-> Maybe c

cancellable: Cancellable

-> m ()

(Can throw GError)

By default, deployment directories are not mutable. This function will allow making them temporarily mutable, for example to allow layering additional non-OSTree content.

deploymentSetPinned

sysrootDeploymentSetPinned

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b)

=> a

self: Sysroot

-> b

deployment: A deployment

-> Bool

isPinned: Whether or not deployment will be automatically GC'd

-> m ()

(Can throw GError)

By default, deployments may be subject to garbage collection. Typical uses of libostree only retain at most 2 deployments. If isPinned is TRUE, a metadata bit will be set causing libostree to avoid automatic GC of the deployment. However, this is really an "advisory" note; it's still possible for e.g. older versions of libostree unaware of pinning to GC the deployment.

This function does nothing and returns successfully if the deployment is already in the desired pinning state. It is an error to try to pin the staged deployment (as it's not in the bootloader entries).

Since: 2018.3

deploymentUnlock

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

-> b

deployment: Deployment

-> DeploymentUnlockedState

unlockedState: Transition to this unlocked state

-> Maybe c

cancellable: Cancellable

-> m ()

(Can throw GError)

Configure the target deployment deployment such that it is writable. There are multiple modes, essentially differing in whether or not any changes persist across reboot.

The OSTREE_DEPLOYMENT_UNLOCKED_HOTFIX state is persistent across reboots.

ensureInitialized

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

self: Sysroot

lock

sysrootLock

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Self

-> m ()

(Can throw GError)

Acquire an exclusive multi-process write lock for self. This call blocks until the lock has been acquired. The lock is not reentrant.

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

self: Sysroot

-> Maybe b

cancellable: Cancellable

Like sysrootCleanup in that it cleans up incomplete deployments and old boot versions, but does NOT prune the repository.

queryDeploymentsFor

sysrootQueryDeploymentsFor

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Sysroot

-> Maybe Text

osname: "stateroot" name

-> m (Deployment, Deployment)

Find the pending and rollback deployments for osname. Pass Nothing for osname to use the booted deployment's osname. By default, pending deployment is the first deployment in the order that matches osname, and rollback will be the next one after the booted deployment, or the deployment after the pending if we're not looking at the booted deployment.

Since: 2017.7

repo

sysrootRepo

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Sysroot

-> m Repo

Returns: The OSTree repository in sysroot self.

This function is a variant of sysrootGetRepo that cannot fail, and returns a cached repository. Can only be called after sysrootLoad has been invoked successfully.

simpleWriteDeployment

sysrootSimpleWriteDeployment

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsDeployment c, IsCancellable d)

=> a

sysroot: Sysroot

-> Maybe Text

osname: OS name

-> b

newDeployment: Prepend this deployment to the list

-> Maybe c

mergeDeployment: Use this deployment for configuration merge

-> [SysrootSimpleWriteDeploymentFlags]

flags: Flags controlling behavior

-> Maybe d

cancellable: Cancellable

-> m ()

(Can throw GError)

Prepend newDeployment to the list of deployments, commit, and cleanup. By default, all other deployments for the given osname except the merge deployment and the booted deployment will be garbage collected.

If SysrootSimpleWriteDeploymentFlagsRetain is specified, then all current deployments will be kept.

If SysrootSimpleWriteDeploymentFlagsRetainPending is specified, then pending deployments will be kept.

If SysrootSimpleWriteDeploymentFlagsRetainRollback is specified, then rollback deployments will be kept.

If SysrootSimpleWriteDeploymentFlagsNotDefault is specified, then instead of prepending, the new deployment will be added right after the booted or merge deployment, instead of first.

If SysrootSimpleWriteDeploymentFlagsNoClean is specified, then no cleanup will be performed after adding the deployment. Make sure to call sysrootCleanup sometime later, instead.

stageTree

sysrootStageTree

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

self: Sysroot

-> Maybe Text

osname: osname to use for merge deployment

-> Text

revision: Checksum to add

-> Maybe KeyFile

origin: Origin to use for upgrades

-> Maybe b

mergeDeployment: Use this deployment for merge path

-> Maybe [Text]

overrideKernelArgv: Use these as kernel arguments; if Nothing, inherit options from provided_merge_deployment

-> Maybe c

cancellable: Cancellable

-> m Deployment

(Can throw GError)

Like sysrootDeployTree, but "finalization" only occurs at OS shutdown time.

tryLock

sysrootTryLock

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Self

-> m Bool

(Can throw GError)

Try to acquire an exclusive multi-process write lock for self. If another process holds the lock, this function will return immediately, setting outAcquired to False, and returning True (and no error).

Release the lock with sysrootUnlock. The lock will also be released if self is deallocated.

unload

sysrootUnload

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Sysroot

-> m ()

Release any resources such as file descriptors referring to the root directory of this sysroot. Normally, those resources are cleared by finalization, but in garbage collected languages that may not be predictable.

This undoes the effect of ostree_sysroot_load().

unlock

sysrootUnlock

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a)

=> a

self: Self

-> m ()

Clear the lock previously acquired with sysrootLock. It is safe to call this function if the lock has not been previously acquired.

writeDeployments

sysrootWriteDeployments

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

self: Sysroot

-> [Deployment]

newDeployments: List of new deployments

-> Maybe b

cancellable: Cancellable

-> m ()

(Can throw GError)

Older version of sysrootWriteDeploymentsWithOptions. This version will perform post-deployment cleanup by default.

writeDeploymentsWithOptions

sysrootWriteDeploymentsWithOptions

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsCancellable b)

=> a

self: Sysroot

-> [Deployment]

newDeployments: List of new deployments

-> SysrootWriteDeploymentsOpts

opts: Options

-> Maybe b

cancellable: Cancellable

-> m ()

(Can throw GError)

Assuming newDeployments have already been deployed in place on disk via sysrootDeployTree, atomically update bootloader configuration. By default, no post-transaction cleanup will be performed. You should invoke sysrootCleanup at some point after the transaction, or specify do_postclean in opts. Skipping the post-transaction cleanup is useful if for example you want to control pruning of the repository.

writeOriginFile

sysrootWriteOriginFile

Arguments

:: (HasCallStack, MonadIO m, IsSysroot a, IsDeployment b, IsCancellable c)

=> a

sysroot: System root

-> b

deployment: Deployment

-> Maybe KeyFile

newOrigin: Origin content

-> Maybe c

cancellable: Cancellable

-> m ()

(Can throw GError)

Immediately replace the origin file of the referenced deployment with the contents of newOrigin. If newOrigin is Nothing, this function will write the current origin of deployment.

Properties

path

No description available in the introspection data.

constructSysrootPath :: (IsSysroot o, IsFile a) => a -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “path” property. This is rarely needed directly, but it is used by new.

getSysrootPath :: (MonadIO m, IsSysroot o) => o -> m File

Get the value of the “path” property. When overloading is enabled, this is equivalent to

get sysroot #path

Signals

journalMsg

type C_SysrootJournalMsgCallback = Ptr () -> CString -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type SysrootJournalMsgCallback

Arguments

 = Text

msg: Human-readable string (should not contain newlines)

-> IO ()

libostree will log to the journal various events, such as the /etc merge status, and transaction completion. Connect to this signal to also synchronously receive the text for those messages. This is intended to be used by command line tools which link to libostree as a library.

Currently, the structured data is only available via the systemd journal.

Since: 2017.10

afterSysrootJournalMsg :: (IsSysroot a, MonadIO m) => a -> SysrootJournalMsgCallback -> m SignalHandlerId

Connect a signal handler for the “journal-msg” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after sysroot #journalMsg callback

genClosure_SysrootJournalMsg :: MonadIO m => SysrootJournalMsgCallback -> m (GClosure C_SysrootJournalMsgCallback)

Wrap the callback into a GClosure.

mk_SysrootJournalMsgCallback :: C_SysrootJournalMsgCallback -> IO (FunPtr C_SysrootJournalMsgCallback)

Generate a function pointer callable from C code, from a C_SysrootJournalMsgCallback.

noSysrootJournalMsgCallback :: Maybe SysrootJournalMsgCallback

A convenience synonym for Nothing :: Maybe SysrootJournalMsgCallback.

onSysrootJournalMsg :: (IsSysroot a, MonadIO m) => a -> SysrootJournalMsgCallback -> m SignalHandlerId

Connect a signal handler for the “journal-msg” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on sysroot #journalMsg callback

wrap_SysrootJournalMsgCallback :: SysrootJournalMsgCallback -> C_SysrootJournalMsgCallback

Wrap a SysrootJournalMsgCallback into a C_SysrootJournalMsgCallback.
