boto.gs.bucket
==============

class class boto.gs.bucket.Bucket(connection=None, name=None, key_class=<class 'boto.gs.key.Key'>)

   Represents a Google Cloud Storage bucket.

   add_email_grant(permission, email_address, recursive=False, headers=None)

      Convenience method that provides a quick way to add an email
      grant to a bucket. This method retrieves the current ACL,
      creates a new grant based on the parameters passed in, adds that
      grant to the ACL and then PUT's the new ACL back to GCS.

      Parameters:
         * **permission** (*string*) -- The permission being granted.
           Should be one of: (READ, WRITE, FULL_CONTROL).

         * **email_address** (*string*) -- The email address
           associated with the GS account your are granting the
           permission to.

         * **recursive** (*bool*) -- A boolean value to controls
           whether the call will apply the grant to all keys within
           the bucket or not.  The default value is False.  By passing
           a True value, the call will iterate through all keys in the
           bucket and apply the same grant to each key. CAUTION: If
           you have a lot of keys, this could take a long time!

   add_group_email_grant(permission, email_address, recursive=False, headers=None)

      Convenience method that provides a quick way to add an email
      group grant to a bucket. This method retrieves the current ACL,
      creates a new grant based on the parameters passed in, adds that
      grant to the ACL and then PUT's the new ACL back to GCS.

      Parameters:
         * **permission** (*string*) -- The permission being granted.
           Should be one of: READ|WRITE|FULL_CONTROL See
           http://code.google.com/apis/storage/docs/developer-
           guide.html#authorization for more details on permissions.

         * **email_address** (*string*) -- The email address
           associated with the Google Group to which you are granting
           the permission.

         * **recursive** (*bool*) -- A boolean value to controls
           whether the call will apply the grant to all keys within
           the bucket or not.  The default value is False.  By passing
           a True value, the call will iterate through all keys in the
           bucket and apply the same grant to each key. CAUTION: If
           you have a lot of keys, this could take a long time!

   add_user_grant(permission, user_id, recursive=False, headers=None)

      Convenience method that provides a quick way to add a canonical
      user grant to a bucket. This method retrieves the current ACL,
      creates a new grant based on the parameters passed in, adds that
      grant to the ACL and then PUTs the new ACL back to GCS.

      Parameters:
         * **permission** (*string*) -- The permission being granted.
           Should be one of: (READ|WRITE|FULL_CONTROL)

         * **user_id** (*string*) -- The canonical user id associated
           with the GS account you are granting the permission to.

           the bucket or not.  The default value is False.  By passing
           a True value, the call will iterate through all keys in the
           bucket and apply the same grant to each key. CAUTION: If
           you have a lot of keys, this could take a long time!

         * **main_page_suffix** (*str*) -- Suffix that is appended to
           a request that is for a "directory" on the website endpoint
           (e.g. if the suffix is index.html and you make a request to
           samplebucket/images/ the data that is returned will be for
           the object with the key name images/index.html). The suffix
           must not be empty and must not include a slash character.
           This parameter is optional and the property is disabled if
           excluded.

         * **error_key** (*str*) -- The object key name to use when a
           400 error occurs. This parameter is optional and the
           property is disabled if excluded.

         * **headers** (*dict*) -- Additional headers to send with the
           request.

   copy_key(new_key_name, src_bucket_name, src_key_name, metadata=None, src_version_id=None, storage_class='STANDARD', preserve_acl=False, encrypt_key=False, headers=None, query_args=None, src_generation=None)

      Create a new key in the bucket by copying an existing key.

      Parameters:
         * **new_key_name** (*string*) -- The name of the new key

         * **src_bucket_name** (*string*) -- The name of the source
           bucket

         * **src_key_name** (*string*) -- The name of the source key

         * **src_generation** (*int*) -- The generation number of the
           source key to copy. If not specified, the latest generation
           is copied.

         * **metadata** (*dict*) -- Metadata to be associated with new
           key.  If metadata is supplied, it will replace the metadata
           of the source key being copied.  If no metadata is
           supplied, the source key's metadata will be copied to the
           new key.

         * **storage_class** (*string*) -- The storage class of the
           new key.  By default, the new key will use the standard
           storage class. Possible values are: STANDARD |
           DURABLE_REDUCED_AVAILABILITY

         * **preserve_acl** (*bool*) -- If True, the ACL from the
           source key will be copied to the destination key.  If
           False, the destination key will have the default ACL.  Note
           that preserving the ACL in the new key object will require
           two additional API calls to GCS, one to retrieve the
           current ACL and one to set that ACL on the new object.  If
           you don't care about the ACL (or if you have a default ACL
           set on the bucket), a value of False will be significantly
           more efficient.

         * **encrypt_key** (*bool*) -- Included for compatibility with
           S3. This argument is ignored.

         * **headers** (*dict*) -- A dictionary of header name/value
           pairs.

   get_all_keys(headers=None, **params)

      A lower-level method for listing contents of a bucket.  This
      closely models the actual S3 API and requires you to manually
      handle the paging of results.  For a higher-level method that

      method.

      Parameters:
         * **max_keys** (*int*) -- The maximum number of keys to
           retrieve

         * **prefix** (*string*) -- The prefix of the keys you want to

           that contain the same string between the prefix and the
           first occurrence of the delimiter will be rolled up into a
           single result element in the CommonPrefixes collection.
           These rolled-up keys are not returned elsewhere in the
           response.

      Return type:
         ResultSet

      Returns:
         The result from S3 listing the keys requested

   get_all_multipart_uploads(headers=None, **params)

      A lower-level, version-aware method for listing active MultiPart
      uploads for a bucket.  This closely models the actual S3 API and
      requires you to manually handle the paging of results.  For a
      higher-level method that handles the details of paging for you,
      you can use the list method.

      Parameters:
         * **max_uploads** (*int*) -- The maximum number of uploads to
           retrieve. Default value is 1000.

         * **key_marker** (*string*) --

           Together with upload_id_marker, this parameter specifies
           the multipart upload after which listing should begin.  If
           upload_id_marker is not specified, only the keys
           lexicographically greater than the specified key_marker
           will be included in the list.

           If upload_id_marker is specified, any multipart uploads for
           a key equal to the key_marker might also be included,
           provided those multipart uploads have upload IDs
           lexicographically greater than the specified
           upload_id_marker.

         * **upload_id_marker** (*string*) -- Together with key-
           marker, specifies the multipart upload after which listing
           should begin. If key_marker is not specified, the
           upload_id_marker parameter is ignored.  Otherwise, any
           multipart uploads for a key equal to the key_marker might
           be included in the list only if they have an upload ID
           lexicographically greater than the specified
           upload_id_marker.

      Return type:
         ResultSet

      Returns:
         The result from S3 listing the uploads requested

   get_all_versions(headers=None, **params)

      A lower-level, version-aware method for listing contents of a
      bucket.  This closely models the actual S3 API and requires you
      to manually handle the paging of results.  For a higher-level
      method that handles the details of paging for you, you can use
      the list method.

      Parameters:
         * **max_keys** (*int*) -- The maximum number of keys to
           retrieve

         * **prefix** (*string*) -- The prefix of the keys you want to
           retrieve

         * **key_marker** (*string*) -- The "marker" of where you are
           in the result set with respect to keys.

         * **version_id_marker** (*string*) -- The "marker" of where
           you are in the result set with respect to version-id's.

         * **delimiter** (*string*) -- If this optional, Unicode
           string parameter is included with your request, then keys
           that contain the same string between the prefix and the
           first occurrence of the delimiter will be rolled up into a
           single result element in the CommonPrefixes collection.
           These rolled-up keys are not returned elsewhere in the
           response.

            configuration.

   get_website_endpoint()

      Returns the fully qualified hostname to use is you want to
      access this bucket as a website.  This doesn't validate whether
      the bucket has been correctly configured as a website or not.

   get_xml_acl(key_name='', headers=None, version_id=None, generation=None)

      Returns the ACL string of the bucket or an object in the bucket.

      Parameters:
         * **key_name** (*str*) -- The name of the object to get the
           ACL for. If not specified, the ACL for the bucket will be
           returned.

         * **headers** (*dict*) -- Additional headers to set during
           the request.

         * **generation** (*int*) -- If specified, gets the ACL for a
           specific generation of a versioned object. If not
           specified, the current version is returned. This parameter
           is only valid when retrieving the ACL of an object, not a
           bucket.

      Return type:
         str

   get_xml_tags()

   initiate_multipart_upload(key_name, headers=None, reduced_redundancy=False, metadata=None, encrypt_key=False, policy=None)

      Start a multipart upload operation.

      Parameters:
         * **key_name** (*string*) -- The name of the key that will
           ultimately result from this multipart upload operation.
           This will be exactly as the key appears in the bucket after
           the upload process has been completed.

         * **headers** (*dict*) -- Additional HTTP headers to send and
           store with the resulting key in S3.

         * **reduced_redundancy** (*boolean*) -- In multipart uploads,
           the storage class is specified when initiating the upload,
           not when uploading individual parts.  So if you want the
           resulting key to use the reduced redundancy storage class
           set this flag when you initiate the upload.

         * **metadata** (*dict*) -- Any metadata that you would like
           to set on the key that results from the multipart upload.

         * **encrypt_key** (*bool*) -- If True, the new copy of the
           object will be encrypted on the server-side by S3 and will
           be stored in an encrypted form while at rest in S3.

         * **policy** ("boto.s3.acl.CannedACLStrings") -- A canned ACL
           policy that will be applied to the new key (once completed)
           in S3.

   list(prefix='', delimiter='', marker='', headers=None)

      List key objects within a bucket.  This returns an instance of
      an BucketListResultSet that automatically handles all of the
      result paging, etc. from S3.  You just need to keep iterating
      until there are no more results.

      Called with no arguments, this will return an iterator object
      across all keys within the bucket.

      The Key objects returned by the iterator are obtained by parsing
      the results of a GET on the bucket, also known as the List
      Objects request.  The XML returned by this request contains only
      a subset of the information about each key.  Certain metadata
      fields such as Content-Type and user metadata are not available
      in the XML. Therefore, if you want these additional metadata
      fields you will have to do a HEAD request on the Key in the
      bucket.

      Parameters:
         * **prefix** (*string*) -- allows you to limit the listing to
           a particular prefix.  For example, if you call the method
           with prefix='/foo/' then the iterator will only cycle
           through the keys that begin with the string '/foo/'.

         * **delimiter** (*string*) -- can be used in conjunction with
           the prefix to allow you to organize and browse your keys
           hierarchically. See http://goo.gl/Xx63h for more details.

         * **marker** (*string*) -- The "marker" of where you are in
           the result set

      Return type:
         "boto.s3.bucketlistresultset.BucketListResultSet"

      Returns:
         an instance of a BucketListResultSet that handles paging, etc

   list_grants(headers=None)

      Returns the ACL entries applied to this bucket.

      Parameters:
         **headers** (*dict*) -- Additional headers to send with the
         request.

      Return type:
         list containing "Entry" objects.

   list_multipart_uploads(key_marker='', upload_id_marker='', headers=None)

      List multipart upload objects within a bucket.  This returns an
      instance of an MultiPartUploadListResultSet that automatically
      handles all of the result paging, etc. from S3.  You just need
      to keep iterating until there are no more results.

      Parameters:
         **marker** (*string*) -- The "marker" of where you are in the
         result set

      Return type:
         "boto.s3.bucketlistresultset.BucketListResultSet"

      Returns:
         an instance of a BucketListResultSet that handles paging, etc

   list_versions(prefix='', delimiter='', marker='', generation_marker='', headers=None)

      List versioned objects within a bucket.  This returns an
      instance of an VersionedBucketListResultSet that automatically
      handles all of the result paging, etc. from GCS.  You just need
      to keep iterating until there are no more results.  Called with
      no arguments, this will return an iterator object across all
      keys within the bucket.

      Parameters:
         * **prefix** (*string*) -- allows you to limit the listing to
           a particular prefix.  For example, if you call the method
           with prefix='/foo/' then the iterator will only cycle
           through the keys that begin with the string '/foo/'.

         * **delimiter** (*string*) -- can be used in conjunction with
           the prefix to allow you to organize and browse your keys
           hierarchically. See:

boto.gs.bucketlistresultset
===========================

class class boto.gs.bucketlistresultset.VersionedBucketListResultSet(bucket=None, prefix='', delimiter='', marker='', generation_marker='', headers=None)

   A resultset for listing versions within a bucket.  Uses the
   bucket_lister generator function and implements the iterator
   interface.  This transparently handles the results paging from GCS
   so even if you have many thousands of keys within the bucket you
   can iterate over all keys in a reasonably efficient manner.

      Convenience method that returns the "CanonicalUserID" of the
      user who's credentials are associated with the connection. The
      only way to get this value is to do a GET request on the service

      of that response, the canonical userid is returned. This method
      simply does all of that and then returns just the user id.

      Return type:
         string

      Returns:
         A string containing the canonical user id.

           The file pointer will be reset to the same position before
           the method returns.

         * **size** (*int*) -- (optional) The Maximum number of bytes
           to read from the file pointer (fp). This is useful when
           uploading a file in multiple parts where the file is being

           available.

      Return type:
         tuple

      Returns:
         A tuple containing the hex digest version of the MD5 hash as
         the first element and the base64 encoded version of the plain
         digest as the second element.

   copy(dst_bucket, dst_key, metadata=None, reduced_redundancy=False, preserve_acl=False, encrypt_key=False, validate_dst_bucket=True)

      Copy this Key to another bucket.

      Parameters:
         * **dst_bucket** (*string*) -- The name of the destination
           bucket

         * **dst_key** (*string*) -- The name of the destination key

         * **metadata** (*dict*) -- Metadata to be associated with new
           key.  If metadata is supplied, it will replace the metadata
           of the source key being copied.  If no metadata is
           supplied, the source key's metadata will be copied to the
           new key.

           the storage class of the new Key to be REDUCED_REDUNDANCY
           regardless of the storage class of the key being copied.
           The Reduced Redundancy Storage (RRS) feature of S3,
           provides lower redundancy at lower storage cost.

         * **preserve_acl** (*bool*) -- If True, the ACL from the
           source key will be copied to the destination key.  If
           False, the destination key will have the default ACL.  Note
           that preserving the ACL in the new key object will require
           two additional API calls to S3, one to retrieve the current
           ACL and one to set that ACL on the new object.  If you
           don't care about the ACL, a value of False will be
           significantly more efficient.

         * **encrypt_key** (*bool*) -- If True, the new copy of the
           object will be encrypted on the server-side by S3 and will
           be stored in an encrypted form while at rest in S3.

         * **validate_dst_bucket** (*bool*) -- If True, will validate
           the dst_bucket by using an extra list request.

      Restore an object from an archive.

      Parameters:
         **days** (*int*) -- The lifetime of the restored object (must
         be at least 1 day).  If the object is already restored then

   send_file(fp, headers=None, cb=None, num_cb=10, query_args=None, chunked_transfer=False, size=None)

      Upload a file to a key into a bucket on S3.

      Parameters:
         * **fp** (*file*) -- The file pointer to upload. The file
           pointer must point point at the offset from which you wish
           to upload. ie. if uploading the full file, it should point
           at the start of the file. Normally when a file is opened
           for reading, the fp will point at the first byte. See the
           bytes parameter below for more info.

         * **headers** (*dict*) -- The headers to pass along with the
           PUT request

         * **cb** (*function*) -- a callback function that will be

           successfully transmitted to S3 and the second representing
           the size of the to be transmitted object.

         * **num_cb** (*int*) -- (optional) If a callback is specified
           with the cb parameter this parameter determines the
           granularity of the callback by defining the maximum number
           of times the callback will be called during the file
           transfer. Providing a negative integer will cause your
           callback to be called with each buffer read.

         * **size** (*int*) -- (optional) The Maximum number of bytes
           to read from the file pointer (fp). This is useful when
           uploading a file in multiple parts where you are splitting
           the file up into different ranges to be uploaded. If not
           specified, the default behaviour is to read all bytes from
           the file pointer. Less bytes may be available.

           "CannedACLStrings".

         * **headers** (*dict*) -- Additional headers to set during
           the request.

         * **generation** (*int*) -- If specified, sets the ACL for a
           specific generation of a versioned object. If not
           specified, the current version is modified.

         * **if_generation** (*int*) -- (optional) If set to a
           generation number, the acl will only be updated if its
           current generation number is this value.

         * **if_metageneration** (*int*) -- (optional) If set to a
           metageneration number, the acl will only be updated if its
           current metageneration number is this value.

   set_contents_from_file(fp, headers=None, replace=True, cb=None, num_cb=10, policy=None, md5=None, res_upload_handler=None, size=None, rewind=False, if_generation=None)

      Store an object in GS using the name of the Key object as the
      key in GS and the contents of the file pointed to by 'fp' as the
      contents.

      Parameters:
         * **fp** (*file*) -- the file whose contents are to be
           uploaded

         * **headers** (*dict*) -- additional HTTP headers to be sent
           with the PUT request.

         * **replace** (*bool*) -- If this parameter is False, the
           method will first check to see if an object exists in the
           bucket with the same key. If it does, it won't overwrite
           it. The default value is True which will overwrite the
           object.

         * **cb** (*function*) -- a callback function that will be
           called to report progress on the upload. The callback
           should accept two integer parameters, the first
           representing the number of bytes that have been
           successfully transmitted to GS and the second representing
           the total number of bytes that need to be transmitted.

         * **num_cb** (*int*) -- (optional) If a callback is specified
           with the cb parameter, this parameter determines the
           granularity of the callback by defining the maximum number
           of times the callback will be called during the file
           transfer.

         * **policy** ("boto.gs.acl.CannedACLStrings") -- A canned ACL
           policy that will be applied to the new key in GS.

         * **md5** (*A tuple containing the hexdigest version of the
           MD5 checksum of the file as the first element and the
           Base64-encoded version of the plain checksum as the second
           element. This is the same format returned by the
           compute_md5 method.*) -- If you need to compute the MD5 for
           any reason prior to upload, it's silly to have to do it
           twice so this param, if present, will be used as the MD5
           values of the file. Otherwise, the checksum will be
           computed.

         * **res_upload_handler** (*ResumableUploadHandler*) -- If
           provided, this handler will perform the upload.

         * **size** (*int*) --

           (optional) The Maximum number of bytes to read from the
           file pointer (fp). This is useful when uploading a file in
           multiple parts where you are splitting the file up into
           different ranges to be uploaded. If not specified, the
           default behaviour is to read all bytes from the file
           pointer. Less bytes may be available. Notes:

              1. The "size" parameter currently cannot be used when a
                 resumable upload handler is given but is still useful
                 for uploading part of a file as implemented by the
                 parent class.

              2. At present Google Cloud Storage does not support
                 multipart uploads.

         * **rewind** (*bool*) -- (optional) If True, the file pointer
           (fp) will be  rewound to the start before any bytes are
           read from it. The default behaviour is False which reads
           from the current position of the file pointer (fp).

         * **if_generation** (*int*) -- (optional) If set to a
           generation number, the object will only be written to if
           its current generation number is this value. If set to the
           value 0, the object will only be written if it doesn't
           already exist.

      Return type:
         int

      Returns:
         The number of bytes written to the key.

      TODO: At some point we should refactor the Bucket and Key
      classes, to move functionality common to all providers into a
      parent class, and provider-specific functionality into
      subclasses (rather than just overriding/sharing code the way it
      currently works).

   set_contents_from_filename(filename, headers=None, replace=True, cb=None, num_cb=10, policy=None, md5=None, reduced_redundancy=None, res_upload_handler=None, if_generation=None)

      Store an object in GS using the name of the Key object as the
      key in GS and the contents of the file named by 'filename'. See
      set_contents_from_file method for details about the parameters.

      Parameters:
         * **filename** (*string*) -- The name of the file that you
           want to put onto GS

         * **headers** (*dict*) -- Additional headers to pass along
           with the request to GS.

         * **replace** (*bool*) -- If True, replaces the contents of
           the file if it already exists.

         * **cb** (*int*) -- (optional) a callback function that will
           be called to report progress on the download. The callback
           should accept two integer parameters, the first
           representing the number of bytes that have been
           successfully transmitted from GS and the second
           representing the total number of bytes that need to be
           transmitted.

         * **num_cb** -- (optional) If a callback is specified with
           the cb parameter this parameter determines the granularity
           of the callback by defining the maximum number of times the
           callback will be called during the file transfer.

         * **policy** ("boto.gs.acl.CannedACLStrings") -- A canned ACL
           policy that will be applied to the new key in GS.

         * **md5** (*A tuple containing the hexdigest version of the
           MD5 checksum of the file as the first element and the
           Base64-encoded version of the plain checksum as the second
           element. This is the same format returned by the
           compute_md5 method.*) -- If you need to compute the MD5 for
           any reason prior to upload, it's silly to have to do it
           twice so this param, if present, will be used as the MD5
           values of the file. Otherwise, the checksum will be
           computed.

         * **res_upload_handler** (*ResumableUploadHandler*) -- If
           provided, this handler will perform the upload.

         * **if_generation** (*int*) -- (optional) If set to a
           generation number, the object will only be written to if
           its current generation number is this value. If set to the
           value 0, the object will only be written if it doesn't
           already exist.

   set_contents_from_stream(*args, **kwargs)

      Store an object using the name of the Key object as the key in
      cloud and the contents of the data stream pointed to by 'fp' as
      the contents.

      The stream object is not seekable and total size is not known.
      This has the implication that we can't specify the Content-Size
      and Content-MD5 in the header. So for huge uploads, the delay in
      calculating MD5 is avoided but with a penalty of inability to
      verify the integrity of the uploaded data.

      Parameters:
         * **fp** (*file*) -- the file whose contents are to be
           uploaded

         * **headers** (*dict*) -- additional HTTP headers to be sent
           with the PUT request.

         * **replace** (*bool*) -- If this parameter is False, the
           method will first check to see if an object exists in the
           bucket with the same key. If it does, it won't overwrite
           it. The default value is True which will overwrite the
           object.

         * **cb** (*function*) -- a callback function that will be
           called to report progress on the upload. The callback
           should accept two integer parameters, the first
           representing the number of bytes that have been
           successfully transmitted to GS and the second representing
           the total number of bytes that need to be transmitted.

         * **num_cb** (*int*) -- (optional) If a callback is specified
           with the cb parameter, this parameter determines the
           granularity of the callback by defining the maximum number
           of times the callback will be called during the file
           transfer.

         * **policy** ("boto.gs.acl.CannedACLStrings") -- A canned ACL
           policy that will be applied to the new key in GS.

         * **reduced_redundancy** (*bool*) -- If True, this will set
           the storage class of the new Key to be REDUCED_REDUNDANCY.
           The Reduced Redundancy Storage (RRS) feature of S3,
           provides lower redundancy at lower storage cost.

         * **size** (*int*) -- (optional) The Maximum number of bytes
           to read from the file pointer (fp). This is useful when
           uploading a file in multiple parts where you are splitting
           the file up into different ranges to be uploaded. If not
           specified, the default behaviour is to read all bytes from
           the file pointer. Less bytes may be available.

         * **if_generation** (*int*) -- (optional) If set to a
           generation number, the object will only be written to if
           its current generation number is this value. If set to the
           value 0, the object will only be written if it doesn't
           already exist.

   set_contents_from_string(s, headers=None, replace=True, cb=None, num_cb=10, policy=None, md5=None, if_generation=None)

      Store an object in S3 using the name of the Key object as the
      key in S3 and the string 's' as the contents. See
      set_contents_from_file method for details about the parameters.

      Parameters:
         * **headers** (*dict*) -- Additional headers to pass along
           with the request to AWS.

         * **replace** (*bool*) -- If True, replaces the contents of
           the file if it already exists.

         * **cb** (*int*) -- a callback function that will be called
           to report progress on the upload.  The callback should
           accept two integer parameters, the first representing the
           number of bytes that have been successfully transmitted to
           S3 and the second representing the size of the to be
           transmitted object.

         * **num_cb** -- (optional) If a callback is specified with
           the cb parameter this parameter determines the granularity
           of the callback by defining the maximum number of times the
           callback will be called during the file transfer.

         * **policy** ("boto.s3.acl.CannedACLStrings") -- A canned ACL
           policy that will be applied to the new key in S3.

         * **md5** (*A tuple containing the hexdigest version of the
           MD5 checksum of the file as the first element and the
           Base64-encoded version of the plain checksum as the second
           element.  This is the same format returned by the
           compute_md5 method.*) -- If you need to compute the MD5 for
           any reason prior to upload, it's silly to have to do it
           twice so this param, if present, will be used as the MD5
           values of the file.  Otherwise, the checksum will be
           computed.

         * **if_generation** (*int*) -- (optional) If set to a
           generation number, the object will only be written to if
           its current generation number is this value. If set to the
           value 0, the object will only be written if it doesn't
           already exist.

boto.gs.resumable_upload_handler
================================

class class boto.gs.resumable_upload_handler.ResumableUploadHandler(tracker_file_name=None, num_retries=None)

   Constructor. Instantiate once for each uploaded file.

   Parameters:
      * **tracker_file_name** (*string*) -- optional file name to save
        tracker URI. If supplied and the current process fails the
        upload, it can be retried in a new process. If called with an
        existing file containing a valid tracker URI, we'll resume the
        upload from this URI; else we'll start a new resumable upload
        (and write the URI to this tracker file).

      * **num_retries** (*int*) -- the number of times we'll re-try a
        resumable upload making no progress. (Count resets every time
        we get progress, so upload can span many more than this number
        of retries.)

   handle_resumable_upload_exception(e, debug)

   send_file(key, fp, headers, cb=None, num_cb=10)

      Upload a file to a key into a bucket on GS, using GS resumable
      upload protocol.

      Parameters:
         * **key** ("boto.s3.key.Key" or subclass) -- The Key object
           to which data is to be uploaded

         * **fp** (*file-like object*) -- The file pointer to upload

         * **headers** (*dict*) -- The headers to pass along with the
           PUT request

         * **cb** (*function*) -- a callback function that will be
           called to report progress on the upload.  The callback
           should accept two integer parameters, the first
           representing the number of bytes that have been
           successfully transmitted to GS, and the second representing
           the total number of bytes that need to be transmitted.

         * **num_cb** (*int*) -- (optional) If a callback is specified
           with the cb parameter, this parameter determines the
           granularity of the callback by defining the maximum number
           of times the callback will be called during the file
           transfer. Providing a negative integer will cause your
           callback to be called with each buffer read.

      Raises ResumableUploadException if a problem occurs during the
      transfer.
