Linode Class

Properties   Methods   Events   Config Settings   Errors  

The Linode class provides an easy way to interface with Linode's Object Storage service.

Syntax

class cloudstorage.Linode

Remarks

The Linode Object Storage service has an API that is compatible with that of Amazon S3, allowing you to store arbitrary data using the same bucket-and-object paradigm that S3 uses.

To use the Linode class, you will first need to sign up for the Linode Object Storage service and obtain an access_key and a secret_key. Then you can start creating buckets in your account using create_bucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using create_object.

There are other methods such as list_buckets, list_objects, get_object, get_link, delete_object etc. that further enable you to manage your data store.

Remarks

If this property is non-empty when list_objects or list_versions is called, any objects (or object versions) whose names contain the same string between the specified object_prefix and the first occurrence of the specified delimiter that follow will be rolled up into a "common prefix" element, which is returned in place of the individual objects themselves.

The on_prefix_list event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the class will also populate the PrefixCount and Prefix[i] configuration settings

Object Hierarchy Traversal

By using the object_delimiter and object_prefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With object_delimiter set to /, we can set object_prefix to successively "deeper" values before calling list_objects or list_versions for the following effect:

This property reflects the size of the part in bytes.

The parts_index parameter specifies the index of the item in the array. The size of the array is controlled by the parts_count property.

This property is read-only.

proxy_auth_scheme Property

This property is used to tell the class which type of authorization to perform when connecting to the proxy.

Syntax

def get_proxy_auth_scheme() -> int: ...
def set_proxy_auth_scheme(value: int) -> None: ...

proxy_auth_scheme = property(get_proxy_auth_scheme, set_proxy_auth_scheme)

Default Value

0

Remarks

This property is used to tell the class which type of authorization to perform when connecting to the proxy. This is used only when the proxy_user and proxy_password properties are set.

proxy_auth_scheme should be set to authNone (3) when no authentication is expected.

By default, proxy_auth_scheme is authBasic (0), and if the proxy_user and proxy_password properties are set, the component will attempt basic authentication.

If proxy_auth_scheme is set to authDigest (1), digest authentication will be attempted instead.

If proxy_auth_scheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If proxy_auth_scheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of proxy_user and proxy_password.

proxy_auto_detect Property

This property tells the class whether or not to automatically detect and use proxy system settings, if available.

Syntax

def get_proxy_auto_detect() -> bool: ...
def set_proxy_auto_detect(value: bool) -> None: ...

def set_proxy_password(value: str) -> None: ...

proxy_password = property(get_proxy_password, set_proxy_password)

Default Value

""

Remarks

This property contains a password if authentication is to be used for the proxy.

If proxy_auth_scheme is set to Basic Authentication, the proxy_user and proxy_password are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If proxy_auth_scheme is set to Digest Authentication, the proxy_user and proxy_password properties are used to respond to the Digest Authentication challenge from the server.

If proxy_auth_scheme is set to NTLM Authentication, the proxy_user and proxy_password properties are used to authenticate through NTLM negotiation.

proxy_port Property

range Property

The range of bytes to request.

Syntax

def get_range() -> str: ...
def set_range(value: str) -> None: ...

range = property(get_range, set_range)

Default Value

""

Remarks

This property specifies the range of bytes to request from the server. If this property is non-empty when a get_object request is being constructed, a header like Range: bytes=Range will be added to the request, with Range substituted with the specified value.

There are two valid formats for this property's value:

• StartByte-
• StartByte-EndByte

Note: If the start_byte property is greater than zero when get_object is called (i.e., when a download is being resumed), and this property is non-empty, the class will automatically advance the StartByte value in the specified range by start_byte bytes when sending the Range header to the server. This ensures that the previously-downloaded data at the start of the specified range is not downloaded again when the download is resumed.

region Property

The region the class will make requests against.

Syntax

def get_region() -> str: ...
def set_region(value: str) -> None: ...

region = property(get_region, set_region)

Default Value

"us-east-1"

Remarks

This property control which region the class will make requests against. By default the class uses us-east-1. This property should be changed to create or access resources in other regions.

Regions:

Important: Each "region" supported by Linode's Object Storage service is actually a completely standalone storage cluster. These clusters do not interact with each other in any way, which causes the following non-standard behaviors:

• Bucket names may be reused in each region (however, they must still be "globally" unique within each region).
• The list_buckets method will only return buckets located in the currently-selected region; there is no way to retrieve a list of all regions' buckets.
• Similarly, the bucket_exists and get_bucket_location methods only consider buckets located in the currently-selected region.
• The copy_object method cannot be used to copy objects to a bucket in another region.

The class will always convert this property's value to lowercase. If this property is cleared, the class will reset it to the default value.

secret_key Property

The secret key to use for authentication.

Syntax

def get_secret_key() -> str: ...
def set_secret_key(value: str) -> None: ...

secret_key = property(get_secret_key, set_secret_key)

Default Value

""

Remarks

This property specifies the secret key that should be used for authentication. Both this property and access_key must be set before attempting any operations which connect to the server.

ssl_accept_server_cert_encoded Property

This is the certificate (PEM/Base64 encoded).

Syntax

def get_ssl_accept_server_cert_encoded() -> bytes: ...
def set_ssl_accept_server_cert_encoded(value: bytes) -> None: ...

ssl_accept_server_cert_encoded = property(get_ssl_accept_server_cert_encoded, set_ssl_accept_server_cert_encoded)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_accept_server_cert_store and ssl_accept_server_cert_subject properties also may be used to specify a certificate.

When ssl_accept_server_cert_encoded is set, a search is initiated in the current ssl_accept_server_cert_store for the private key of the certificate. If the key is found, ssl_accept_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_accept_server_cert_subject is set to an empty string.

ssl_cert_encoded Property

This is the certificate (PEM/Base64 encoded).

Syntax

def get_ssl_cert_encoded() -> bytes: ...
def set_ssl_cert_encoded(value: bytes) -> None: ...

ssl_cert_encoded = property(get_ssl_cert_encoded, set_ssl_cert_encoded)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_cert_store and ssl_cert_subject properties also may be used to specify a certificate.

When ssl_cert_encoded is set, a search is initiated in the current ssl_cert_store for the private key of the certificate. If the key is found, ssl_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_cert_subject is set to an empty string.

ssl_cert_store Property

This is the name of the certificate store for the client certificate.

Syntax

def get_ssl_cert_store() -> bytes: ...
def set_ssl_cert_store(value: bytes) -> None: ...

ssl_cert_store = property(get_ssl_cert_store, set_ssl_cert_store)

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The ssl_cert_store_type property denotes the type of the certificate store specified by ssl_cert_store. If the store is password protected, specify the password in ssl_cert_store_password.

ssl_cert_store is used in conjunction with the ssl_cert_subject property to specify client certificates. If ssl_cert_store has a value, and ssl_cert_subject or ssl_cert_encoded is set, a search for a certificate is initiated. Please see the ssl_cert_subject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

ssl_cert_store_password Property

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

def get_ssl_cert_store_password() -> str: ...
def set_ssl_cert_store_password(value: str) -> None: ...

ssl_cert_store_password = property(get_ssl_cert_store_password, set_ssl_cert_store_password)

Default Value

""

Remarks

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

ssl_cert_store_type Property

This is the type of certificate store for this certificate.

Syntax

def get_ssl_cert_store_type() -> int: ...
def set_ssl_cert_store_type(value: int) -> None: ...

ssl_cert_store_type = property(get_ssl_cert_store_type, set_ssl_cert_store_type)

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This property can take one of the following values:

ssl_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_ssl_cert_subject() -> str: ...
def set_ssl_cert_subject(value: str) -> None: ...

ssl_cert_subject = property(get_ssl_cert_subject, set_ssl_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

ssl_provider Property

This specifies the SSL/TLS implementation to use.

Syntax

def get_ssl_provider() -> int: ...
def set_ssl_provider(value: int) -> None: ...

ssl_provider = property(get_ssl_provider, set_ssl_provider)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

ssl_server_cert_encoded Property

This is the certificate (PEM/Base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

start_byte Property

The byte offset from which to resume the upload or download.

Syntax

def get_start_byte() -> int: ...
def set_start_byte(value: int) -> None: ...

start_byte = property(get_start_byte, set_start_byte)

Default Value

0

Remarks

This property specifies the byte offset from which to resume an automatic multipart upload initiated by create_object, or a download initiated by get_object. Refer to those methods' documentation for more information about resuming uploads and downloads.

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

use_virtual_hosting Property

Determines which style request to use.

Syntax

def get_use_virtual_hosting() -> bool: ...
def set_use_virtual_hosting(value: bool) -> None: ...

use_virtual_hosting = property(get_use_virtual_hosting, set_use_virtual_hosting)

Default Value

TRUE

Remarks

If set to True (default), buckets will be referenced in the request using the hosted-style request: http://yourbucket.us-east-1.linodeobjects.com/yourobject. If False, the class will use the path-style request: http://us-east-1.linodeobjects.com/yourbucket/yourobject.

Note: When set to True, there are more limitations when choosing a bucket name due to DNS server naming restrictions.

version_id Property

The object version to make requests against.

Syntax

def get_version_id() -> str: ...
def set_version_id(value: str) -> None: ...

version_id = property(get_version_id, set_version_id)

Default Value

""

Remarks

This property can be set to the Id of a specific object version before calling the following methods in order to make requests against the specified object version instead of the base object; refer to each one's documentation for more information:

• copy_object (to copy from a specific object version)
• delete_object
• get_link (to build a link for a specific object version)
• get_object
• get_object_info
• send_custom_request
• update_object_acl

Refer to Amazon's Versioning documentation for more information about versioning.

versioning_enabled Property

Controls whether versioning is enabled for the currently selected bucket.

Syntax

def get_versioning_enabled() -> bool: ...
def set_versioning_enabled(value: bool) -> None: ...

versioning_enabled = property(get_versioning_enabled, set_versioning_enabled)

Default Value

FALSE

Remarks

This property can be used to query and control whether the bucket currently selected by bucket has versioning enabled.

Note that if bucket is empty, or refers to a bucket that does not exist, this property will always return False when queried, and any attempts to set it will fail.

Refer to Amazon's Versioning documentation for more information about versioning.

version_marker Property

A marker indicating what page of object versions to return next.

Syntax

def get_version_marker() -> str: ...
def set_version_marker(value: str) -> None: ...

version_marker = property(get_version_marker, set_version_marker)

Default Value

Remarks

This property will be populated when list_versions is called if the results are paged and there are more pages. To list all object versions, continue to call list_versions until this property returns empty string.

Refer to list_versions for more information.

abort_multipart_upload Method

Aborts a multipart upload.

Syntax

def abort_multipart_upload(object_name: str, upload_id: str) -> None: ...

Remarks

This method aborts the multipart upload of the object named ObjectName specified by UploadId.

When this method is called, all parts that have been uploaded for the multipart upload are deleted from the server. (Note that if any part uploads are currently in progress, it may be necessary to call this method again after they complete.)

If this method is called successfully, the specified UploadId will no longer be valid.

add_metadata Method

Adds a metadata item to the Metadata properties.

Syntax

def add_metadata(name: str, value: str) -> None: ...

Remarks

This method adds a metadata item to the Metadata* properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.

If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The class will take care of prepending it when sending metadata to the server.

add_query_param Method

Adds a query parameter to the QueryParams properties.

Syntax

def add_query_param(name: str, value: str) -> None: ...

Remarks

This method is used to add a query parameter to the QueryaParam* properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the class automatically. Consult the service documentation for details on the available parameters.

bucket_exists Method

Checks whether the bucket exists.

Syntax

def bucket_exists() -> bool: ...

Remarks

This method checks whether the bucket specified by bucket exists, returning True if so or False if not.

Note: This method only considers buckets located in the currently-selected region. Refer to the region property's documentation for more information.

check_versioning_enabled Method

Checks whether versioning is enabled for the currently selected bucket.

Syntax

def check_versioning_enabled() -> bool: ...

Remarks

This method can be used to check whether the bucket currently selected by bucket has versioning enabled.

Note that if bucket is empty, or refers to a bucket that does not exist, this method will always return False when queried.

Refer to Amazon's Versioning documentation for more information about versioning.

complete_multipart_upload Method

Completes a multipart upload by assembling previously uploaded parts.

Syntax

def complete_multipart_upload(object_name: str, upload_id: str) -> None: ...

Remarks

This method completes the multipart upload specified by UploadId. The server will assemble all of the parts that have been uploaded into an object named ObjectName.

Note that this method automatically calls list_parts internally to obtain the information needed to complete the multipart upload. This process does not alter the Parts* properties, nor does it cause the on_part_list event to fire.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

copy_object Method

Copies an object.

Syntax

def copy_object(src_object_name: str, dest_bucket: str, dest_object_name: str) -> None: ...

Remarks

This method copies the object specified by SrcObjectName (in the bucket currently selected by bucket) to the object specified by DestObjectName in DestBucket. If DestBucket is empty, the bucket specified by bucket is used as the destination bucket.

If the version_id property is non-empty, the specified version of the source object will be used as the copy source. In this case, DestObjectName may be the same as SrcObjectName to "promote" the version, copying its contents back to the base object.

If there are any metadata items present in the Metadata* properties, they will set on the destination object; otherwise, the server will copy any metadata items present on the source object to the destination object.

Notes:

• Objects may only be copied to buckets that exist within the same region.
• Objects larger than 5GB cannot be copied using this method. To copy such objects, start a new multipart upload for the destination object using start_multipart_upload, and then use the copy_part method to create parts for said multipart upload using the source object's data.

copy_part Method

Copies the specified object as a part of a multipart upload.

Syntax

def copy_part(src_object_name: str, dest_bucket: str, dest_object_name: str, dest_part_number: int, dest_upload_id: str) -> None: ...

Remarks

This method copies data from the object specified by SrcObjectName (in the bucket currently selected by bucket) to a new multipart upload part for DestObjectName in DestBucket.

The DestPartNumber and DestUploadId parameters should be used in the same manner as the upload_part method's PartNumber and UploadId parameters.

To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.

create_bucket Method

Creates a new bucket.

Syntax

def create_bucket() -> None: ...

Remarks

This method creates a new bucket using the name specified by the bucket property. The bucket is created in the region specified by the region property.

create_object Method

Creates a new object in the currently selected bucket.

Syntax

def create_object(object_name: str) -> None: ...

Remarks

This method creates a new object named Object in the bucket currently selected by bucket. If there are any metadata items present in the Metadata* properties, they will included in the creation request.

If local_file is set the file will be uploaded from the specified path. If local_file is not set the data in object_data will be used.

To encrypt the file before uploading it, set encryption_algorithm and encryption_password.

This method can automatically handle the multipart upload of objects (See Below). If it is desired to manually take control of the multipart upload process see start_multipart_upload.

Automatic Multipart Uploads

If more than SimpleUploadLimit bytes of data are provided, the class will automatically perform a multipart upload by splitting the data up into parts (sized according to the FragmentSize configuration setting) and uploading them individually. To accomplish this, the class automatically makes calls to start_multipart_upload, upload_part, and complete_multipart_upload internally; tracks upload state information using the ResumableUploadState configuration setting; and tracks how much data has been uploaded using the start_byte property. The on_fragment_complete event will fire after each part is uploaded.

If, during an automatic multipart upload, any individual request fails, the upload can be resumed be calling this method again with the same parameters, so long as ResumableUploadState and start_byte contain the same values as they did when the upload was interrupted.

When an automatic multipart upload completes successfully, ResumableUploadState is cleared and start_byte is reset to 0.

delete_bucket Method

Deletes a bucket.

Syntax

def delete_bucket() -> None: ...

Remarks

This method deletes the bucket currently selected by bucket. Note that bucket names share a global namespace, and it may not be possible to recreate a deleted bucket if its name has been taken by another user in the meantime.

delete_object Method

Deletes an object.

Syntax

def delete_object(object_name: str) -> None: ...

Remarks

This method deletes the object specified by ObjectName in the bucket currently selected by bucket.

If the version_id property is non-empty, this method deletes the specified version of the object instead.

Deleting Versioned Objects

If an object's latest version is a delete marker, then the server treats the object as if it didn't exist (i.e., it doesn't appear when listing objects, cannot be downloaded, etc.). However, all of the previous versions of the object (including one that existed just before the delete marker was created) still exist; they can be listed using list_versions, and explicitly interacted with by setting version_id and calling an appropriate method.

To permanently delete objects in a versioning-enabled bucket, each version of the object must be explicitly deleted by setting version_id before calling this method. This includes any delete marker versions, which can be deleted like any other version.

Refer to Amazon's Deleting Object Versions, Working with Delete Markers, and Removing Delete Markers articles for more information.

disable_versioning Method

Disables versioning for the currently selected bucket.

Syntax

def disable_versioning() -> None: ...

Remarks

This method can be used to disable versioning for the bucket currently selected by bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

do_events Method

Processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

enable_versioning Method

Enables versioning for the currently selected bucket.

Syntax

def enable_versioning() -> None: ...

Remarks

This method can be used to enable versioning for the bucket currently selected by bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

get_bucket_location Method

Gets a bucket's location.

Syntax

def get_bucket_location() -> str: ...

Remarks

This method retrieves and returns the location (i.e., region) of the bucket currently selected by bucket.

Note: This method only considers buckets located in the currently-selected region. Refer to the region property's documentation for more information.

get_link Method

Creates a link that provides access to an object for a specified amount of time.

Syntax

def get_link(object_name: str, expires: int) -> str: ...

Remarks

This method creates and returns a pre-authenticated link that provides access to the object specified by ObjectName in the bucket currently selected by bucket. If the version_id property is non-empty, a link is created for the specified version of the object.

The Expires parameter specifies how many seconds the link should be valid for. The maximum validity period is seven days.

Note that this method is an offline method that simply generates a pre-signed URL; no communication with the server takes place.

get_object Method

Downloads an object.

Syntax

def get_object(object_name: str) -> None: ...

Remarks

This methods downloads the object specified by ObjectName in the bucket currently selected by bucket. If the version_id property is non-empty, the specified version of the object is downloaded instead. The range property can be used to download a specific range of bytes from the object.

If local_file is set, the object data will be saved to the specified location; otherwise, the object data will be held by object_data.

To download and decrypt an encrypted object, set encryption_algorithm and encryption_password before calling this method.

Download Notes

In the simplest use-case, downloading an object looks like this: s3.LocalFile = "../MyData.zip"; s3.GetObject(s3.Objects[0].Name);

Resuming Downloads

The class also supports resuming failed downloads by using the start_byte property. If a download is interrupted, set start_byte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyData.zip"; s3.LocalFile = downloadFile; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded file s3.StartByte = new FileInfo(downloadFile).Length; s3.GetObject(s3.Objects[0].Name);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when local_file was set in the initial download attempt.

If local_file is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with start_byte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to local_file. s3.LocalFile = "../MyData.zip"; s3.EncryptionPassword = "password"; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded temp file s3.StartByte = new FileInfo(s3.Config("DownloadTempFile")).Length; s3.GetObject(s3.Objects[0].Name);

get_object_info Method

Gets an object's information and metadata.

Syntax

def get_object_info(object_name: str) -> None: ...

Remarks

This method gets information and metadata for the object specified by Object in the bucket currently selected by bucket. If the version_id property is non-empty, information and metadata for the specified version of the object is retrieved instead.

Calling this method will fire the on_object_list and on_metadata_list events, and will re-populate the Objects* and Metadata* properties.

interrupt Method

Interrupt the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

list_buckets Method

Lists all buckets in the currently-selected region.

Syntax

def list_buckets() -> None: ...

Remarks

This method lists all buckets in the currently-selected region. (Due to the architecture of the Linode Object Storage service, there is no way to retrieve a list of all regions' buckets; refer to the region property for more information.)

Calling this method will fire the on_bucket_list event once for each bucket, and will also populate the Buckets* properties.

list_multipart_uploads Method

Lists the current multipart uploads.

Syntax

def list_multipart_uploads() -> None: ...

Remarks

This method lists the current multipart uploads in the bucket currently selected by bucket.

Before calling this method, the object_prefix property may be set in order to restrict the results to only the multipart uploads whose names begin with a given string. The object_delimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the on_object_list event once for each multipart upload, and will also populate the Objects* properties.

If there are still more multipart uploads available to list when this method returns, the object_marker property will be populated. Continue to call this method until object_marker is empty to accumulate all pages of results in the Objects* properties.

list_objects Method

Lists the objects in a bucket.

Syntax

def list_objects() -> None: ...

Remarks

This method lists the objects in the bucket currently selected by bucket.

Before calling this method, the object_prefix property may be set in order to restrict the results to only the objects whose names begin with a given string. The object_delimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the on_object_list event once for each object, and will also populate the Objects* properties. It may also fire the on_prefix_list event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more objects available to list when this method returns, the object_marker property will be populated. Continue to call this method until object_marker is empty to accumulate all pages of results in the Objects* properties.

Object Hierarchy Traversal

By using the object_delimiter and object_prefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With object_delimiter set to /, we can set object_prefix to successively "deeper" values before calling list_objects or list_versions for the following effect:

list_parts Method

Lists the parts in a multipart upload.

Syntax

def list_parts(object_name: str, upload_id: str) -> None: ...

Remarks

This method lists the parts in the multipart upload of ObjectName specified by UploadId. The MaxParts configuration setting may be used to limit the number of results returned.

Calling this method will fire the on_part_list event once for each part, and will also populate the Parts* properties.

If there are still more parts available to list when this method returns, the part_marker property will be populated. Continue to call this method until part_marker is empty to accumulate all pages of results in the Parts* properties.

Note that this method does not need to be called before attempting to complete a multipart upload with complete_multipart_upload; the class will automatically collect the necessary information internally. Refer to complete_multipart_upload for more information.

list_versions Method

Lists the object versions in a bucket.

Syntax

def list_versions() -> None: ...

Remarks

This method lists the object versions in the bucket currently selected by bucket.

Before calling this method, the object_prefix property may be set in order to restrict the results to only the object versions whose names begin with a given string. The object_delimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the on_object_list event once for each object version, and will also populate the Objects* properties. It may also fire the on_prefix_list event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more object versions available to list when this method returns, the version_marker property will be populated. Continue to call this method until version_marker is empty to accumulate all pages of results in the Objects* properties.

Object Hierarchy Traversal

By using the object_delimiter and object_prefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With object_delimiter set to /, we can set object_prefix to successively "deeper" values before calling list_objects or list_versions for the following effect:

reset Method

Resets the class to its initial state.

Syntax

def reset() -> None: ...

Remarks

This method resets the class to its initial state.

reset_headers Method

Resets all HTTP headers, cookies, and LocalFile.

Syntax

def reset_headers() -> None: ...

Remarks

Resets all the HTTP headers as well as local_file to "" (empty string), and clears the Metadata* and QueryParam* properties.

Call this method before creating a new request, so that headers and query parameters from the previous request are not carried over to the next one.

send_custom_request Method

Sends a custom request to the server.

Syntax

def send_custom_request(http_method: str, object_name: str, request_body: str) -> None: ...

Remarks

This method can be used to send arbitrary requests to the server.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• DELETE

The ObjectName and RequestBody parameters may be empty if not needed.

Usage

When this method is called, the class does the following:

1. Builds a request URL, including query parameters, based on the following:
   • use_ssl, region, and use_virtual_hosting for the base URL.
     • Alternatively, if a custom URL has been specified using the URL configuration setting, it is used directly, and these properties are ignored.
   • bucket (if non-empty)
   • ObjectName (if non-empty)
   • version_id (if both it and ObjectName are non-empty)
   • QueryParam*
2. Adds request headers from:
   • content_disposition
   • content_type
   • other_headers
   • ProductToken
   • SessionToken
   • UserToken
3. Signs the request (unless the SignCustomRequest configuration setting is disabled).
4. Sends the request, including RequestBody if non-empty.
5. Stores the response headers in the ParsedHeader* properties; and the response body in the specified local_file, or object_data (using the same logic as get_object).

If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

start_multipart_upload Method

Starts a new manual multipart upload.

Syntax

def start_multipart_upload(object_name: str) -> str: ...

Remarks

This method starts a new "manual" multipart upload for an object named ObjectName, in the bucket currently selected by bucket, and returns the upload Id that the server associates with it. For an "automatic" multipart upload see the create_object method. This upload Id can then be used to call the following methods:

• upload_part
• copy_part
• list_parts
• complete_multipart_upload
• abort_multipart_upload

If there are any metadata items present in the Metadata* properties, they will be included in the creation request, and will be applied to the final object after the multipart upload is completed with complete_multipart_upload.

Multipart uploads never expire, they must be explicitly completed or aborted using complete_multipart_upload or abort_multipart_upload. The list_multipart_uploads method can be used to retrieve a list of current multipart uploads.

update_bucket_acl Method

Updates a bucket's canned access policy.

Syntax

def update_bucket_acl() -> None: ...

Remarks

This method updates the canned access policy of the bucket selected by bucket to the value specified by access_policy

update_object_acl Method

Updates an object's canned access policy.

Syntax

def update_object_acl(object_name: str) -> None: ...

Remarks

This method updates the caned access policy of the objects specified by ObjectName, in the bucket currently selected by bucket, to the value specified by access_policy.

If the version_id property is non-empty, the canned access policy of the specified version of the object is updated instead.

upload_part Method

Uploads a multipart upload part.

Syntax

def upload_part(object_name: str, part_number: int, upload_id: str) -> None: ...

Remarks

This method uploads a part for the multipart upload of the object named ObjectName specified by UploadId.

PartNumber specifies the part's number; it must be a value in the range 1 to 10000, inclusive. If a part with the given number already exists in the specified multipart upload, it is replaced with the newly-uploaded part.

The data to upload is taken from either local_file or object_data (whichever data is found in first, when checked in that order). Each part must be at least 5MB in size, except for the last part in the overall multipart upload, which can be any non-zero size.

If the IncludePartMD5 configuration setting is True, the class will include an MD5 digest of its data when sending it to the server. The server will then verify that the data was received without corruption.

on_bucket_list Event

Fires once for each bucket returned when listing buckets.

Syntax

class LinodeBucketListEventParams(object):
  @property
  def bucket_name() -> str: ...

  @property

@on_bucket_list.setter
def on_bucket_list(event_hook: Callable[[LinodeBucketListEventParams], None]) -> None: ...

Remarks

This event fires once for each bucket returned when list_buckets is called.

BucketName reflects the name of the bucket.

CreationDate reflects the bucket's creation date.

OwnerId and OwnerName reflect the Id and display name of the bucket's owner, respectively.

on_end_transfer Event

This event fires when a document finishes transferring.

Syntax

class LinodeEndTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class Linode:
@property
def on_end_transfer() -> Callable[[LinodeEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[LinodeEndTransferEventParams], None]) -> None: ...

Remarks

The on_end_transfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_error Event

Fired when information is available about errors during data delivery.

Syntax

class LinodeErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class Linode:
@property
def on_error() -> Callable[[LinodeErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[LinodeErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_fragment_complete Event

Fires after each part in an automatic multipart upload is complete.

Syntax

class LinodeFragmentCompleteEventParams(object):
  @property
  def fragment_number() -> int: ...

  @property

@property
def on_fragment_complete() -> Callable[[LinodeFragmentCompleteEventParams], None]: ...
@on_fragment_complete.setter
def on_fragment_complete(event_hook: Callable[[LinodeFragmentCompleteEventParams], None]) -> None: ...

Remarks

If, when create_object is called, more than SimpleUploadLimit bytes of upload data are present, the class will automatically split the upload data up into parts and perform a multipart upload. During the overall upload process, this event will fire after each part is uploaded, providing an indication of overall upload progress.

FragmentNumber is the number of the current part that has completed. This value starts at 1.

FragmentCount is the total number of parts that will be uploaded.

Interrupt can be set to True to interrupt the upload. The upload may be resumed later.

Refer to create_object for more information.

on_header Event

Syntax

class LinodeLogEventParams(object):
  @property
  def log_level() -> int: ...

  @property
  def message() -> str: ...

Syntax

class LinodePrefixListEventParams(object):
  @property
  def bucket_name() -> str: ...

  @property
  def prefix() -> str: ...

# In class Linode:
@property
def on_prefix_list() -> Callable[[LinodePrefixListEventParams], None]: ...
@on_prefix_list.setter
def on_prefix_list(event_hook: Callable[[LinodePrefixListEventParams], None]) -> None: ...

Remarks

This event fires once for each common prefix returned when list_objects or list_versions is called when object_delimiter is non-empty. Refer to object_delimiter for more information.

BucketName reflects the name of the bucket that the prefix is in.

Prefix is the common prefix.

on_progress Event

Fires during an upload or download to indicate transfer progress.

Syntax

class LinodeProgressEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def total_bytes() -> int: ...

  @property
  def percent_done() -> int: ...

# In class Linode:
@property
def on_progress() -> Callable[[LinodeProgressEventParams], None]: ...
@on_progress.setter
def on_progress(event_hook: Callable[[LinodeProgressEventParams], None]) -> None: ...

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the class tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class LinodeSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class Linode:
@property
def on_ssl_server_authentication() -> Callable[[LinodeSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[LinodeSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class LinodeSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class Linode:
@property
def on_ssl_status() -> Callable[[LinodeSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[LinodeSSLStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

on_start_transfer Event

This event fires when a document starts transferring (after the headers).

Syntax

class LinodeStartTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class Linode:
@property
def on_start_transfer() -> Callable[[LinodeStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[LinodeStartTransferEventParams], None]) -> None: ...

Remarks

The on_start_transfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_transfer Event

This event is fired while a document transfers (delivers document).

Syntax

class LinodeTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

# In class Linode:
@property
def on_transfer() -> Callable[[LinodeTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[LinodeTransferEventParams], None]) -> None: ...

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
