boto

class boto.NullHandler(level=0)

class boto.connection.ConnectionPool

A connection pool that expires connections after a fixed period of time. This saves time spent waiting for a connection that AWS has timed out on the other end.

This class is thread-safe.

CLEAN_INTERVAL = 5.0
STALE_DURATION = 60.0
clean()

Clean up the stale connections in all of the pools, and then get rid of empty pools. Pools clean themselves every time a connection is fetched; this cleaning takes care of pools that aren’t being used any more, so nothing is being gotten from them.

get_http_connection(host, is_secure)

Gets a connection from the pool for the named host. Returns None if there is no connection that can be reused. It’s the caller’s responsibility to call close() on the connection when it’s no longer needed.

put_http_connection(host, is_secure, conn)

Adds a connection to the pool of connections that can be reused for the named host.

size()

Returns the number of connections in the pool.

class boto.connection.HTTPRequest(method, protocol, host, port, path, auth_path, params, headers, body)

Represents an HTTP request.

Parameters:
  • method (string) – The HTTP method name, ‘GET’, ‘POST’, ‘PUT’ etc.
  • protocol (string) – The http protocol used, ‘http’ or ‘https’.
  • host (string) – Host to which the request is addressed. eg. abc.com
  • port (int) – port on which the request is being sent. Zero means unset, in which case default port will be chosen.
  • path (string) – URL path that is being accessed.
  • path – The part of the URL path used when creating the authentication string.
  • params (dict) – HTTP url query parameters, with key as name of the param, and value as value of param.
  • headers (dict) – HTTP headers, with key as name of the header and value as value of header.
  • body (string) – Body of the HTTP request. If not present, will be None or empty string (‘’).
authorize(connection, **kwargs)
class boto.connection.HostConnectionPool

A pool of connections for one remote (host,is_secure).

When connections are added to the pool, they are put into a pending queue. The _mexe method returns connections to the pool before the response body has been read, so they connections aren’t ready to send another request yet. They stay in the pending queue until they are ready for another request, at which point they are returned to the pool of ready connections.

The pool of ready connections is an ordered list of (connection,time) pairs, where the time is the time the connection was returned from _mexe. After a certain period of time, connections are considered stale, and discarded rather than being reused. This saves having to wait for the connection to time out if AWS has decided to close it on the other end because of inactivity.

Thread Safety:

This class is used only fram ConnectionPool while it’s mutex is held.
clean()

Get rid of stale connections.

get()

Returns the next connection in this pool that is ready to be reused. Returns None of there aren’t any.

put(conn)

Adds a connection to the pool, along with the time it was added.

size()

Returns the number of connections in the pool for this host. Some of the connections may still be in use, and may not be ready to be returned by get().

boto.handler

boto.resultset

class boto.resultset.BooleanResult(marker_elem=None)
endElement(name, value, connection)
startElement(name, attrs, connection)
to_boolean(value, true_value='true')
class boto.resultset.ResultSet(marker_elem=None)

The ResultSet is used to pass results back from the Amazon services to the client. It is light wrapper around Python’s list class, with some additional methods for parsing XML results from AWS. Because I don’t really want any dependencies on external libraries, I’m using the standard SAX parser that comes with Python. The good news is that it’s quite fast and efficient but it makes some things rather difficult.

You can pass in, as the marker_elem parameter, a list of tuples. Each tuple contains a string as the first element which represents the XML element that the resultset needs to be on the lookout for and a Python class as the second element of the tuple. Each time the specified element is found in the XML, a new instance of the class will be created and popped onto the stack.

Variables:next_token (str) – A hash used to assist in paging through very long result sets. In most cases, passing this value to certain methods will give you another ‘page’ of results.

boto.utils

Some handy utility functions used by several classes.

class boto.utils.AuthSMTPHandler(mailhost, username, password, fromaddr, toaddrs, subject)

This class extends the SMTPHandler in the standard Python logging module to accept a username and password on the constructor and to then use those credentials to authenticate with the SMTP server. To use this, you could add something like this in your boto config file:

[handler_hand07] class=boto.utils.AuthSMTPHandler level=WARN formatter=form07 args=(‘localhost’, ‘username’, ‘password’, 'from@abc‘, ['user1@abc‘, 'user2@xyz‘], ‘Logger Subject’)

Initialize the handler.

We have extended the constructor to accept a username/password for SMTP authentication.

emit(record)

Emit a record.

Format the record and send it to the specified addressees. It would be really nice if I could add authorization to this class without having to resort to cut and paste inheritance but, no.

class boto.utils.LRUCache(capacity)

A dictionary-like object that stores only a certain number of items, and discards its least recently used item when full.

>>> cache = LRUCache(3)
>>> cache['A'] = 0
>>> cache['B'] = 1
>>> cache['C'] = 2
>>> len(cache)
3
>>> cache['A']
0

Adding new items to the cache does not increase its size. Instead, the least recently used item is dropped:

>>> cache['D'] = 3
>>> len(cache)
3
>>> 'B' in cache
False

Iterating over the cache returns the keys, starting with the most recently used:

>>> for key in cache:
...     print key
D
A
C

This code is based on the LRUCache class from Genshi which is based on Mighty’s LRUCache from myghtyutils.util, written by Mike Bayer and released under the MIT license (Genshi uses the BSD License). See:

class boto.utils.Password(str=None, hashfunc=None)

Password object that stores itself as hashed. Hash defaults to SHA512 if available, MD5 otherwise.

Load the string from an initial value, this should be the raw hashed password.

hashfunc()

Returns a sha512 hash object; optionally initialized with a string

set(value)
class boto.utils.ShellCommand(command, wait=True, fail_fast=False, cwd=None)
getOutput()
getStatus()
output

run(cwd=None)
setReadOnly(value)
status

The exit code for the command

boto.utils.canonical_string(method, path, headers, expires=None, provider=None)
boto.utils.compute_md5(fp, buf_size=8192, size=None)

Compute MD5 hash on passed file and return results in a tuple of values.

Parameters:
  • fp (file) – File pointer to the file to MD5 hash. The file pointer will be reset to its current location before the method returns.
  • buf_size (integer) – Number of bytes per read request.
  • 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 split inplace into different parts. Less bytes may be available.
Return type:

tuple

Returns:

A tuple containing the hex digest version of the MD5 hash as the first element, the base64 encoded version of the plain digest as the second element and the data size as the third element.

boto.utils.fetch_file(uri, file=None, username=None, password=None)

Fetch a file based on the URI provided. If you do not pass in a file pointer a tempfile.NamedTemporaryFile, or None if the file could not be retrieved is returned. The URI can be either an HTTP url, or “s3://bucket_name/key_name”

boto.utils.find_class(module_name, class_name=None)
