ShareLeaseClient

Constructor

ShareLeaseClient(client: ShareFileClient | ShareClient, lease_id: str | None = None)

Parameters

Name	Description
client Required	ShareFileClient or ShareClient The client of the file or share to lease.
lease_id	str A string representing the lease ID of an existing lease. This value does not need to be specified in order to acquire a new lease, or break one. default value: None

Variables

Name	Description
id	str The ID of the lease currently being maintained. This will be None if no lease has yet been acquired.
etag	str The ETag of the lease currently being maintained. This will be None if no lease has yet been acquired or modified.
last_modified	datetime The last modified timestamp of the lease currently being maintained. This will be None if no lease has yet been acquired or modified.

Methods

acquire	Requests a new lease. This operation establishes and manages a lock on a file or share for write and delete operations. If the file or share does not have an active lease, the File or Share service creates a lease on the file or share. If the file has an active lease, you can only request a new lease using the active lease ID. If the file or share does not have an active lease, the File or Share service creates a lease on the file and returns a new lease ID.
break_lease	Force breaks the lease if the file or share has an active lease. Any authorized request can break the lease; the request is not required to specify a matching lease ID. An infinite lease breaks immediately. Once a lease is broken, it cannot be changed. Any authorized request can break the lease; the request is not required to specify a matching lease ID. When a lease is successfully broken, the response indicates the interval in seconds until a new lease can be acquired.
change	Changes the lease ID of an active lease. A change must include the current lease ID in x-ms-lease-id and a new lease ID in x-ms-proposed-lease-id.
release	Releases the lease. The lease may be released if the lease ID specified on the request matches that associated with the share or file. Releasing the lease allows another client to immediately acquire the lease for the share or file as soon as the release is complete.
renew	Renews the share lease. The share lease can be renewed if the lease ID specified in the lease client matches that associated with the share. Note that the lease may be renewed even if it has expired as long as the share has not been leased again since the expiration of that lease. When you renew a lease, the lease duration clock resets. New in version 12.6.0.

acquire

Requests a new lease. This operation establishes and manages a lock on a file or share for write and delete operations. If the file or share does not have an active lease, the File or Share service creates a lease on the file or share. If the file has an active lease, you can only request a new lease using the active lease ID.

If the file or share does not have an active lease, the File or Share service creates a lease on the file and returns a new lease ID.

async acquire(**kwargs: Any) -> None

Keyword-Only Parameters

Name	Description
lease_duration	int Specifies the duration of the lease, in seconds, or negative one (-1) for a lease that never expires. File leases never expire. A non-infinite share lease can be between 15 and 60 seconds. A share lease duration cannot be changed using renew or change. Default is -1 (infinite share lease).
timeout	int Sets the server-side timeout for the operation in seconds. For more details see https://learn.microsoft.com/rest/api/storageservices/setting-timeouts-for-file-service-operations. This value is not tracked or validated on the client. To configure client-side network timesouts see here.

Returns

Type	Description
None

break_lease

Force breaks the lease if the file or share has an active lease. Any authorized request can break the lease; the request is not required to specify a matching lease ID. An infinite lease breaks immediately.

Once a lease is broken, it cannot be changed. Any authorized request can break the lease; the request is not required to specify a matching lease ID. When a lease is successfully broken, the response indicates the interval in seconds until a new lease can be acquired.

async break_lease(**kwargs: Any) -> int

Keyword-Only Parameters

Name	Description
lease_break_period	int This is the proposed duration of seconds that the share lease should continue before it is broken, between 0 and 60 seconds. This break period is only used if it is shorter than the time remaining on the share lease. If longer, the time remaining on the share lease is used. A new share lease will not be available before the break period has expired, but the share lease may be held for longer than the break period. If this header does not appear with a break operation, a fixed-duration share lease breaks after the remaining share lease period elapses, and an infinite share lease breaks immediately. New in version 12.5.0.
timeout	int Sets the server-side timeout for the operation in seconds. For more details see https://learn.microsoft.com/rest/api/storageservices/setting-timeouts-for-file-service-operations. This value is not tracked or validated on the client. To configure client-side network timesouts see here.

Returns

Type	Description
int	Approximate time remaining in the lease period, in seconds.

change

Changes the lease ID of an active lease. A change must include the current lease ID in x-ms-lease-id and a new lease ID in x-ms-proposed-lease-id.

async change(proposed_lease_id: str, **kwargs: Any) -> None

Parameters

Name	Description
proposed_lease_id Required	str Proposed lease ID, in a GUID string format. The File or Share service raises an error (Invalid request) if the proposed lease ID is not in the correct format.

Returns

Type	Description
	None

release

Releases the lease. The lease may be released if the lease ID specified on the request matches that associated with the share or file. Releasing the lease allows another client to immediately acquire the lease for the share or file as soon as the release is complete.
