The protocol + recognizes three parts to a request: + + 1. One line identifying the request type and path + 2. An optional set of RFC-822-style headers + 3. An optional data part + + The headers and data are separated by a blank line. + + The first line of the request has the form + + + + where is a (case-sensitive) keyword such as GET or POST, + is a string containing path information for the request, + and should be the string "HTTP/1.0" or "HTTP/1.1". + is encoded using the URL encoding scheme (using %xx to signify + the ASCII character with hex code xx). + + The specification specifies that lines are separated by CRLF but + for compatibility with the widest range of clients recommends + servers also handle LF. Similarly, whitespace in the request line + is treated sensibly (allowing multiple spaces between components + and allowing trailing whitespace). + + Similarly, for output, lines ought to be separated by CRLF pairs + but most clients grok LF characters just fine. + + If the first line of the request has the form + + + + (i.e. is left out) then this is assumed to be an HTTP + 0.9 request; this form has no optional headers and data part and + the reply consists of just the data. + + The reply form of the HTTP 1.x protocol again has three parts: + + 1. One line giving the response code + 2. An optional set of RFC-822-style headers + 3. The data + + Again, the headers and data are separated by a blank line. + + The response code line has the form + + + + where is the protocol version ("HTTP/1.0" or "HTTP/1.1"), + is a 3-digit response code indicating success or + failure of the request, and is an optional + human-readable string explaining what the response code means. + + This server parses the request and the headers, and then calls a + function specific to the request type (). Specifically, + a request SPAM will be handled by a method do_SPAM(). If no + such method exists the server sends an error response to the + client. If it exists, it is called with no arguments: + + do_SPAM() + + Note that the request name is case sensitive (i.e. SPAM and spam + are different requests). + + The various request details are stored in instance variables: + + - client_address is the client IP address in the form (host, + port); + + - command, path and version are the broken-down request line; + + - headers is an instance of email.message.Message (or a derived + class) containing the header information; + + - rfile is a file object open for reading positioned at the + start of the optional input data part; + + - wfile is a file object open for writing. + + IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING! + + The first thing to be written must be the response line. Then + follow 0 or more header lines, then a blank line, and then the + actual data (if any). The meaning of the header lines depends on + the command executed by the server; in most cases, when data is + returned, there should be at least one header line of the form + + Content-type: / + + where and should be registered MIME types, + e.g. "text/html" or "text/plain". + + """ + + # The Python system version, truncated to its first component. + sys_version = "Python/" + sys.version.split()[0] + + # The server software version.

For +instance, a threading UDP server class is created as follows: + + class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass + +The Mix-in class must come first, since it overrides a method defined +in UDPServer! Setting the various member variables also changes +the behavior of the underlying server mechanism. + +To implement a service, you must derive a class from +BaseRequestHandler and redefine its handle() method. You can then run +various versions of the service by combining one of the server classes +with your request handler class. + +The request handler class must be different for datagram or stream +services. This can be hidden by using the request handler +subclasses StreamRequestHandler or DatagramRequestHandler. + +Of course, you still have to use your head! + +For instance, it makes no sense to use a forking server if the service +contains state in memory that can be modified by requests (since the +modifications in the child process would never reach the initial state +kept in the parent process and passed to each child). In this case, +you can use a threading server, but you will probably have to use +locks to avoid two requests that come in nearly simultaneous to apply +conflicting changes to the server state. + +On the other hand, if you are building e.g. an HTTP server, where all +data is stored externally (e.g. in the file system), a synchronous +class will essentially render the service "deaf" while one request is +being handled -- which may be for a very long time if a client is slow +to read all the data it has requested. Here a threading or forking +server is appropriate. + +In some cases, it may be appropriate to process part of a request +synchronously, but to finish processing in a forked child depending on +the request data. This can be implemented by using a synchronous +server and doing an explicit fork in the request handler class +handle() method. + +Another approach to handling multiple simultaneous requests in an +environment that supports neither threads nor fork (or where these are +too expensive or inappropriate for the service) is to maintain an +explicit table of partially finished requests and to use select() to +decide which request to work on next (or whether to handle a new +incoming request).

The temporary socket is + then closed and deleted, and the ephemeral port is returned. + + Either this method or bind_port() should be used for any tests where a + server socket needs to be bound to a particular port for the duration of + the test. Which one to use depends on whether the calling code is creating + a python socket, or if an unused port needs to be provided in a constructor + or passed to an external program (i.e. the -accept argument to openssl's + s_server mode). Always prefer bind_port() over find_unused_port() where + possible. Hard coded ports should *NEVER* be used. As soon as a server + socket is bound to a hard coded port, the ability to run multiple instances + of the test simultaneously on the same host is compromised, which makes the + test a ticking time bomb in a buildbot environment.

When + accept() is called on each socket, the second caller's process will steal + the port from the first caller, leaving them both in an awkwardly wedged + state where they'll no longer respond to any signals or graceful kills, and + must be forcibly killed via OpenProcess()/TerminateProcess(). + + The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option + instead of SO_REUSEADDR, which effectively affords the same semantics as + SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open + Source world compared to Windows ones, this is a common mistake.

It opens the URL and returns the results as file-like +object; the returned object has some extra methods described below. + +The OpenerDirector manages a collection of Handler objects that do +all the actual work. Each Handler implements a particular protocol or +option. The OpenerDirector is a composite object that invokes the +Handlers needed to open the requested URL. For example, the +HTTPHandler performs HTTP GET and POST requests and deals with +non-error returns. The HTTPRedirectHandler automatically deals with +HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler +deals with digest authentication. + +urlopen(url, data=None) -- Basic usage is the same as original +urllib. pass the url and optionally data to post to an HTTP URL, and +get a file-like object back. One difference is that you can also pass +a Request instance instead of URL.

-For socket-based servers: - -- address family: - - AF_INET{,6}: IP (Internet Protocol) sockets (default) - - AF_UNIX: Unix domain sockets - - others, e.g. AF_DECNET are conceivable (see -- socket type: - - SOCK_STREAM (reliable stream, e.g. TCP) - - SOCK_DGRAM (datagrams, e.g. UDP) - -For request-based servers (including socket-based): - -- client address verification before further looking at the request - (This is actually a hook for any processing that needs to look - at the request before anything else, e.g. logging) -- how to handle multiple requests: - - synchronous (one request is handled at a time) - - forking (each request is handled by a new process) - - threading (each request is handled by a new thread) - -The classes in this module favor the server type that is simplest to -write: a synchronous TCP/IP server. This is bad class design, but -save some typing. (There's also the issue that a deep class hierarchy -slows down method lookups.) - -There are five classes in an inheritance diagram, four of which represent -synchronous servers of four types: - - +------------+ - | BaseServer | - +------------+ - | - v - +-----------+ +------------------+ - | TCPServer |------->| UnixStreamServer | - +-----------+ +------------------+ - | - v - +-----------+ +--------------------+ - | UDPServer |------->| UnixDatagramServer | - +-----------+ +--------------------+ - -Note that UnixDatagramServer derives from UDPServer, not from -UnixStreamServer -- the only difference between an IP and a Unix -stream server is the address family, which is simply repeated in both -unix server classes. - -Forking and threading versions of each type of server can be created -using the ForkingMixIn and ThreadingMixIn mix-in classes. For -instance, a threading UDP server class is created as follows: - - class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass - -The Mix-in class must come first, since it overrides a method defined -in UDPServer! Setting the various member variables also changes -the behavior of the underlying server mechanism. - -To implement a service, you must derive a class from -BaseRequestHandler and redefine its handle() method. You can then run -various versions of the service by combining one of the server classes -with your request handler class. - -The request handler class must be different for datagram or stream -services. This can be hidden by using the request handler -subclasses StreamRequestHandler or DatagramRequestHandler. - -Of course, you still have to use your head! - -For instance, it makes no sense to use a forking server if the service -contains state in memory that can be modified by requests (since the -modifications in the child process would never reach the initial state -kept in the parent process and passed to each child). In this case, -you can use a threading server, but you will probably have to use -locks to avoid two requests that come in nearly simultaneous to apply -conflicting changes to the server state. - -On the other hand, if you are building e.g. an HTTP server, where all -data is stored externally (e.g. in the file system), a synchronous -class will essentially render the service "deaf" while one request is -being handled -- which may be for a very long time if a client is slow -to read all the data it has requested. Here a threading or forking -server is appropriate. - -In some cases, it may be appropriate to process part of a request -synchronously, but to finish processing in a forked child depending on -the request data. This can be implemented by using a synchronous -server and doing an explicit fork in the request handler class -handle() method. - -Another approach to handling multiple simultaneous requests in an -environment that supports neither threads nor fork (or where these are -too expensive or inappropriate for the service) is to maintain an -explicit table of partially finished requests and to use select() to -decide which request to work on next (or whether to handle a new -incoming request).

The temporary socket is - then closed and deleted, and the ephemeral port is returned. - - Either this method or bind_port() should be used for any tests where a - server socket needs to be bound to a particular port for the duration of - the test. Which one to use depends on whether the calling code is creating - a python socket, or if an unused port needs to be provided in a constructor - or passed to an external program (i.e. the -accept argument to openssl's - s_server mode). Always prefer bind_port() over find_unused_port() where - possible. Hard coded ports should *NEVER* be used. As soon as a server - socket is bound to a hard coded port, the ability to run multiple instances - of the test simultaneously on the same host is compromised, which makes the - test a ticking time bomb in a buildbot environment.

On Unix, you can't have two AF_INET SOCK_STREAM sockets bind, - listen and then accept connections on identical host/ports. An EADDRINUSE - socket.error will be raised at some point (depending on the platform and - the order bind and listen were called on each socket). - - However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE - will ever be raised when attempting to bind two identical host/ports. When - accept() is called on each socket, the second caller's process will steal - the port from the first caller, leaving them both in an awkwardly wedged - state where they'll no longer respond to any signals or graceful kills, and - must be forcibly killed via OpenProcess()/TerminateProcess(). - - The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option - instead of SO_REUSEADDR, which effectively affords the same semantics as - SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open - Source world compared to Windows ones, this is a common mistake. A quick - look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when - openssl.exe is called with the 's_server' option, for example.

For example, the -HTTPHandler performs HTTP GET and POST requests and deals with -non-error returns. The HTTPRedirectHandler automatically deals with -HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler -deals with digest authentication. - -urlopen(url, data=None) -- Basic usage is the same as original -urllib. pass the url and optionally data to post to an HTTP URL, and -get a file-like object back. One difference is that you can also pass -a Request instance instead of URL. Raises a URLError (subclass of -IOError); for HTTP errors, raises an HTTPError, which can also be -treated as a valid response. - -build_opener -- Function that creates a new OpenerDirector instance. -Will install the default handlers. Accepts one or more Handlers as -arguments, either instances or Handler classes that it will -instantiate. If one of the argument is a subclass of the default -handler, the argument will be installed instead of the default. - -install_opener -- Installs a new opener as the default opener. - -objects of interest: - -OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages -the Handler classes, while dealing with requests and responses. - -Request -- An object that encapsulates the state of a request. The -state can be as simple as the URL. It can also include extra HTTP -headers, e.g. a User-Agent. - -BaseHandler -- - -internals: -BaseHandler and parent -_call_chain conventions - -Example usage: - -import urllib.request - -# set up authentication info -authinfo = urllib.request.HTTPBasicAuthHandler() -authinfo.add_password(realm='PDQ Application', - uri='https://mahler:8092/site-updates.py', - user='klem', - passwd='geheim$parole') - -proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"}) - -# build a new opener that adds authentication and caching FTP handlers -opener = urllib.request.build_opener(proxy_support, authinfo, - urllib.request.CacheFTPHandler) - -# install it -urllib.request.install_opener(opener) - -f = urllib.request.urlopen('http://www.python.org/') -""" - -# XXX issues: -# If an authentication error handler that tries to perform -# authentication for some reason but fails, how should the error be -# signalled?

For example, it - is impossible to tell whether the server will close the connection - UNTIL the response headers have been read; this means that further - requests cannot be placed into the pipeline until it is known that - the server will NOT be closing the connection. - -Logical State __state __response -------------- ------- ---------- -Idle _CS_IDLE None -Request-started _CS_REQ_STARTED None -Request-sent _CS_REQ_SENT None -Unread-response _CS_IDLE -Req-started-unread-response _CS_REQ_STARTED -Req-sent-unread-response _CS_REQ_SENT -""" - -from array import array -import os -import socket -from sys import py3kwarning -from urlparse import urlsplit -import warnings -with warnings.catch_warnings(): - if py3kwarning: - warnings.filterwarnings("ignore", ".*mimetools has been removed", - DeprecationWarning) - import mimetools - -try: - from cStringIO import StringIO -except ImportError: - from StringIO import StringIO - -__all__ = ["HTTP", "HTTPResponse", "HTTPConnection", - "HTTPException", "NotConnected", "UnknownProtocol", - "UnknownTransferEncoding", "UnimplementedFileMode", - "IncompleteRead", "InvalidURL", "ImproperConnectionState", - "CannotSendRequest", "CannotSendHeader", "ResponseNotReady", - "BadStatusLine", "error", "responses"] - -HTTP_PORT = 80 -HTTPS_PORT = 443 - -_UNKNOWN = 'UNKNOWN' - -# connection states -_CS_IDLE = 'Idle' -_CS_REQ_STARTED = 'Request-started' -_CS_REQ_SENT = 'Request-sent' - -# status codes -# informational -CONTINUE = 100 -SWITCHING_PROTOCOLS = 101 -PROCESSING = 102 - -# successful -OK = 200 -CREATED = 201 -ACCEPTED = 202 -NON_AUTHORITATIVE_INFORMATION = 203 -NO_CONTENT = 204 -RESET_CONTENT = 205 -PARTIAL_CONTENT = 206 -MULTI_STATUS = 207 -IM_USED = 226 - -# redirection -MULTIPLE_CHOICES = 300 -MOVED_PERMANENTLY = 301 -FOUND = 302 -SEE_OTHER = 303 -NOT_MODIFIED = 304 -USE_PROXY = 305 -TEMPORARY_REDIRECT = 307 - -# client error -BAD_REQUEST = 400 -UNAUTHORIZED = 401 -PAYMENT_REQUIRED = 402 -FORBIDDEN = 403 -NOT_FOUND = 404 -METHOD_NOT_ALLOWED = 405 -NOT_ACCEPTABLE = 406 -PROXY_AUTHENTICATION_REQUIRED = 407 -REQUEST_TIMEOUT = 408 -CONFLICT = 409 -GONE = 410 -LENGTH_REQUIRED = 411 -PRECONDITION_FAILED = 412 -REQUEST_ENTITY_TOO_LARGE = 413 -REQUEST_URI_TOO_LONG = 414 -UNSUPPORTED_MEDIA_TYPE = 415 -REQUESTED_RANGE_NOT_SATISFIABLE = 416 -EXPECTATION_FAILED = 417 -UNPROCESSABLE_ENTITY = 422 -LOCKED = 423 -FAILED_DEPENDENCY = 424 -UPGRADE_REQUIRED = 426 - -# server error -INTERNAL_SERVER_ERROR = 500 -NOT_IMPLEMENTED = 501 -BAD_GATEWAY = 502 -SERVICE_UNAVAILABLE = 503 -GATEWAY_TIMEOUT = 504 -HTTP_VERSION_NOT_SUPPORTED = 505 -INSUFFICIENT_STORAGE = 507 -NOT_EXTENDED = 510 - -# Mapping status codes to official W3C names -responses = { - 100: 'Continue', - 101: 'Switching Protocols', - - 200: 'OK', - 201: 'Created', - 202: 'Accepted', - 203: 'Non-Authoritative Information', - 204: 'No Content', - 205: 'Reset Content', - 206: 'Partial Content', - - 300: 'Multiple Choices', - 301: 'Moved Permanently', - 302: 'Found', - 303: 'See Other', - 304: 'Not Modified', - 305: 'Use Proxy', - 306: '(Unused)', - 307: 'Temporary Redirect', - - 400: 'Bad Request', - 401: 'Unauthorized', - 402: 'Payment Required', - 403: 'Forbidden', - 404: 'Not Found', - 405: 'Method Not Allowed', - 406: 'Not Acceptable', - 407: 'Proxy Authentication Required', - 408: 'Request Timeout', - 409: 'Conflict', - 410: 'Gone', - 411: 'Length Required', - 412: 'Precondition Failed', - 413: 'Request Entity Too Large', - 414: 'Request-URI Too Long', - 415: 'Unsupported Media Type', - 416: 'Requested Range Not Satisfiable', - 417: 'Expectation Failed', - - 500: 'Internal Server Error', - 501: 'Not Implemented', - 502: 'Bad Gateway', - 503: 'Service Unavailable', - 504: 'Gateway Timeout', - 505: 'HTTP Version Not Supported', -} - -# maximal amount of data to read at one time in _safe_read -MAXAMOUNT = 1048576 - -# maximal line length when calling readline(). -_MAXLINE = 65536 - -class HTTPMessage(mimetools.Message): - - def addheader(self, key, value): - """Add header for field key handling repeats.""" - prev = self.dict.get(key) - if prev is None: - self.dict[key] = value - else: - combined = ", ".join((prev, value)) - self.dict[key] = combined - - def addcontinue(self, key, more): - """Add more field data from a continuation line.""" - prev = self.dict[key] - self.dict[key] = prev + "\n " + more - - def readheaders(self): - """Read header lines. - - Read header lines up to the entirely blank line that terminates them. - The (normally blank) line that ends the headers is skipped, but not - included in the returned list.

You can change the header and printed -attributes by using the .output() function - - >>> C = Cookie.SmartCookie() - >>> C["rocky"] = "road" - >>> C["rocky"]["path"] = "/cookie" - >>> print C.output(header="Cookie:") - Cookie: rocky=road; Path=/cookie - >>> print C.output(attrs=[], header="Cookie:") - Cookie: rocky=road - -The load() method of a Cookie extracts cookies from a string.

String objects are *not* serialized. Similarly, -when the load() method parses out values, it attempts to de-serialize -the value.

-This module tries to capture the various aspects of defining a server: - -For socket-based servers: - -- address family: - - AF_INET{,6}: IP (Internet Protocol) sockets (default) - - AF_UNIX: Unix domain sockets - - others, e.g. AF_DECNET are conceivable (see -- socket type: - - SOCK_STREAM (reliable stream, e.g. TCP) - - SOCK_DGRAM (datagrams, e.g. UDP) - -For request-based servers (including socket-based): - -- client address verification before further looking at the request - (This is actually a hook for any processing that needs to look - at the request before anything else, e.g. logging) -- how to handle multiple requests: - - synchronous (one request is handled at a time) - - forking (each request is handled by a new process) - - threading (each request is handled by a new thread) - -The classes in this module favor the server type that is simplest to -write: a synchronous TCP/IP server. This is bad class design, but -save some typing. (There's also the issue that a deep class hierarchy -slows down method lookups.) - -There are five classes in an inheritance diagram, four of which represent -synchronous servers of four types: - - +------------+ - | BaseServer | - +------------+ - | - v - +-----------+ +------------------+ - | TCPServer |------->| UnixStreamServer | - +-----------+ +------------------+ - | - v - +-----------+ +--------------------+ - | UDPServer |------->| UnixDatagramServer | - +-----------+ +--------------------+ - -Note that UnixDatagramServer derives from UDPServer, not from -UnixStreamServer -- the only difference between an IP and a Unix -stream server is the address family, which is simply repeated in both -unix server classes. - -Forking and threading versions of each type of server can be created -using the ForkingMixIn and ThreadingMixIn mix-in classes. For -instance, a threading UDP server class is created as follows: - - class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass - -The Mix-in class must come first, since it overrides a method defined -in UDPServer! Setting the various member variables also changes -the behavior of the underlying server mechanism. - -To implement a service, you must derive a class from -BaseRequestHandler and redefine its handle() method. You can then run -various versions of the service by combining one of the server classes -with your request handler class. - -The request handler class must be different for datagram or stream -services. This can be hidden by using the request handler -subclasses StreamRequestHandler or DatagramRequestHandler. - -Of course, you still have to use your head! - -For instance, it makes no sense to use a forking server if the service -contains state in memory that can be modified by requests (since the -modifications in the child process would never reach the initial state -kept in the parent process and passed to each child). In this case, -you can use a threading server, but you will probably have to use -locks to avoid two requests that come in nearly simultaneous to apply -conflicting changes to the server state. - -On the other hand, if you are building e.g. an HTTP server, where all -data is stored externally (e.g. in the file system), a synchronous -class will essentially render the service "deaf" while one request is -being handled -- which may be for a very long time if a client is slow -to read all the data it has requested. Here a threading or forking -server is appropriate. - -In some cases, it may be appropriate to process part of a request -synchronously, but to finish processing in a forked child depending on -the request data. This can be implemented by using a synchronous -server and doing an explicit fork in the request handler class -handle() method. - -Another approach to handling multiple simultaneous requests in an -environment that supports neither threads nor fork (or where these are -too expensive or inappropriate for the service) is to maintain an -explicit table of partially finished requests and to use select() to -decide which request to work on next (or whether to handle a new -incoming request).

The temporary socket is - then closed and deleted, and the ephemeral port is returned. - - Either this method or bind_port() should be used for any tests where a - server socket needs to be bound to a particular port for the duration of - the test. Which one to use depends on whether the calling code is creating - a python socket, or if an unused port needs to be provided in a constructor - or passed to an external program (i.e. the -accept argument to openssl's - s_server mode). Always prefer bind_port() over find_unused_port() where - possible. Hard coded ports should *NEVER* be used. As soon as a server - socket is bound to a hard coded port, the ability to run multiple instances - of the test simultaneously on the same host is compromised, which makes the - test a ticking time bomb in a buildbot environment.

On Unix, you can't have two AF_INET SOCK_STREAM sockets bind, - listen and then accept connections on identical host/ports. An EADDRINUSE - socket.error will be raised at some point (depending on the platform and - the order bind and listen were called on each socket). - - However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE - will ever be raised when attempting to bind two identical host/ports. When - accept() is called on each socket, the second caller's process will steal - the port from the first caller, leaving them both in an awkwardly wedged - state where they'll no longer respond to any signals or graceful kills, and - must be forcibly killed via OpenProcess()/TerminateProcess(). - - The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option - instead of SO_REUSEADDR, which effectively affords the same semantics as - SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open - Source world compared to Windows ones, this is a common mistake.

For +instance, a threading UDP server class is created as follows: + + class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass + +The Mix-in class must come first, since it overrides a method defined +in UDPServer! Setting the various member variables also changes +the behavior of the underlying server mechanism. + +To implement a service, you must derive a class from +BaseRequestHandler and redefine its handle() method. You can then run +various versions of the service by combining one of the server classes +with your request handler class. + +The request handler class must be different for datagram or stream +services. This can be hidden by using the request handler +subclasses StreamRequestHandler or DatagramRequestHandler. + +Of course, you still have to use your head! + +For instance, it makes no sense to use a forking server if the service +contains state in memory that can be modified by requests (since the +modifications in the child process would never reach the initial state +kept in the parent process and passed to each child). In this case, +you can use a threading server, but you will probably have to use +locks to avoid two requests that come in nearly simultaneous to apply +conflicting changes to the server state. + +On the other hand, if you are building e.g. an HTTP server, where all +data is stored externally (e.g. in the file system), a synchronous +class will essentially render the service "deaf" while one request is +being handled -- which may be for a very long time if a client is slow +to read all the data it has requested. Here a threading or forking +server is appropriate. + +In some cases, it may be appropriate to process part of a request +synchronously, but to finish processing in a forked child depending on +the request data. This can be implemented by using a synchronous +server and doing an explicit fork in the request handler class +handle() method. + +Another approach to handling multiple simultaneous requests in an +environment that supports neither threads nor fork (or where these are +too expensive or inappropriate for the service) is to maintain an +explicit table of partially finished requests and to use select() to +decide which request to work on next (or whether to handle a new +incoming request).

The temporary socket is + then closed and deleted, and the ephemeral port is returned. + + Either this method or bind_port() should be used for any tests where a + server socket needs to be bound to a particular port for the duration of + the test. Which one to use depends on whether the calling code is creating + a python socket, or if an unused port needs to be provided in a constructor + or passed to an external program (i.e. the -accept argument to openssl's + s_server mode). Always prefer bind_port() over find_unused_port() where + possible. Hard coded ports should *NEVER* be used. As soon as a server + socket is bound to a hard coded port, the ability to run multiple instances + of the test simultaneously on the same host is compromised, which makes the + test a ticking time bomb in a buildbot environment. On Unix buildbots, this + may simply manifest as a failed test, which can be recovered from without + intervention in most cases, but on Windows, the entire python process can + completely and utterly wedge, requiring someone to log in to the buildbot + and manually kill the affected process. + + (This is easy to reproduce on Windows, unfortunately, and can be traced to + the SO_REUSEADDR socket option having different semantics on Windows versus + Unix/Linux. On Unix, you can't have two AF_INET SOCK_STREAM sockets bind, + listen and then accept connections on identical host/ports. An EADDRINUSE + socket.error will be raised at some point (depending on the platform and + the order bind and listen were called on each socket). + + However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE + will ever be raised when attempting to bind two identical host/ports. When + accept() is called on each socket, the second caller's process will steal + the port from the first caller, leaving them both in an awkwardly wedged + state where they'll no longer respond to any signals or graceful kills, and + must be forcibly killed via OpenProcess()/TerminateProcess(). + + The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option + instead of SO_REUSEADDR, which effectively affords the same semantics as + SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open + Source world compared to Windows ones, this is a common mistake. A quick + look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when + openssl.exe is called with the 's_server' option, for example.

Each Handler implements a particular protocol or +option. The OpenerDirector is a composite object that invokes the +Handlers needed to open the requested URL.

There are also some -tests that try to exhaust the address space of the process, which only makes -sense on 32-bit systems with at least 2Gb of memory. The passed-in memlimit, -which is a string in the form of '2.5Gb', determines howmuch memory the -tests will limit themselves to (but they may go slightly over.)

On the other hand, it is no use running these tests with a -limit of less than 2.5Gb, and many require more than 20Gb. Tests that expect -to use more than memlimit memory will be skipped. The big-memory tests -generally run very, very long. - --u is used to specify which special resource intensive tests to run, -such as those requiring large file support or network connectivity. -The argument is a comma-separated list of words indicating the -resources to test. Currently only the following are defined: - - all - Enable all special resources. - - audio - Tests that use the audio device. (There are known - cases of broken audio drivers that can crash Python or - even the Linux kernel.) - - curses - Tests that use curses and will modify the terminal's - state and output modes. - - largefile - It is okay to run some test that may create huge - files. These tests can take a long time and may - consume >2GB of disk space temporarily. - - network - It is okay to run tests that use external network - resource, e.g. testing SSL support for sockets. - - bsddb - It is okay to run the bsddb testsuite, which takes - a long time to complete. - - decimal - Test the decimal module against a large suite that - verifies compliance with standards. - - cpu - Used for certain CPU-heavy tests. - - subprocess Run all tests for the subprocess module. - - urlfetch - It is okay to download files required on testing. - - gui - Run tests that require a running GUI. - - xpickle - Test pickle and cPickle against Python 2.4, 2.5 and 2.6 to - test backwards compatibility. These tests take a long time - to run. - -To enable all resources except one, use '-uall,-'. For -example, to run all the tests except for the bsddb tests, give the -option '-uall,-bsddb'. -""" - -from __future__ import print_function - -import StringIO -import getopt -import json -import os -import random -import re -import shutil -import sys -import time -import traceback -import warnings -import unittest -import tempfile -import imp -import platform -import sysconfig - - -# Some times __path__ and __file__ are not absolute (e.g. while running from -# Lib/) and, if we change the CWD to run the tests in a temporary dir, some -# imports might fail.

The big-memory tests -generally run very, very long. - --u is used to specify which special resource intensive tests to run, -such as those requiring large file support or network connectivity. -The argument is a comma-separated list of words indicating the -resources to test. Currently only the following are defined: - - all - Enable all special resources. - - audio - Tests that use the audio device.

The docs ask that an Eastern tzinfo class consider such a time to +be EDT (because it's "after 2"), which is a redundant spelling of 1:MM EST +on the day DST starts. We want to return the 1:MM EST spelling because that's +the only spelling that makes sense on the local wall clock. + +In fact, if [5] holds at this point, we do have the standard-time spelling, +but that takes a bit of proof. We first prove a stronger result. What's the +difference between the LHS and RHS of [5]? Let + + diff = x.n - (z.n - z.o) [6] + +Now + z.n = by [4] + (y + y.s).n = by #5 + y.n + y.s = since y.n = x.n + x.n + y.s = since z and y are have the same tzinfo member, + y.s = z.s by #2 + x.n + z.s + +Plugging that back into [6] gives + + diff = + x.n - ((x.n + z.s) - z.o) = expanding + x.n - x.n - z.s + z.o = cancelling + - z.s + z.o = by #2 + z.d + +So diff = z.d. + +If [5] is true now, diff = 0, so z.d = 0 too, and we have the standard-time +spelling we wanted in the endcase described above. We're done. Contrarily, +if z.d = 0, then we have a UTC equivalent, and are also done. + +If [5] is not true now, diff = z.d != 0, and z.d is the offset we need to +add to z (in effect, z is in tz's standard time, and we need to shift the +local clock into tz's daylight time). + +Let + + z' = z + z.d = z + diff [7] + +and we can again ask whether + + z'.n - z'.o = x.n [8] + +If so, we're done. If not, the tzinfo class is insane, according to the +assumptions we've made. This also requires a bit of proof. As before, let's +compute the difference between the LHS and RHS of [8] (and skipping some of +the justifications for the kinds of substitutions we've done several times +already): + + diff' = x.n - (z'.n - z'.o) = replacing z'.n via [7] + x.n - (z.n + diff - z'.o) = replacing diff via [6] + x.n - (z.n + x.n - (z.n - z.o) - z'.o) = + x.n - z.n - x.n + z.n - z.o + z'.o = cancel x.n + - z.n + z.n - z.o + z'.o = cancel z.n + - z.o + z'.o = #1 twice + -z.s - z.d + z'.s + z'.d = z and z' have same tzinfo + z'.d - z.d + +So z' is UTC-equivalent to x iff z'.d = z.d at this point. If they are equal, +we've found the UTC-equivalent so are done. In fact, we stop with [7] and +return z', not bothering to compute z'.d. + +How could z.d and z'd differ? z' = z + z.d [7], so merely moving z' by +a dst() offset, and starting *from* a time already in DST (we know z.d != 0), +would have to change the result dst() returns: we start in DST, and moving +a little further into it takes us out of DST. + +There isn't a sane case where this can happen. The closest it gets is at +the end of DST, where there's an hour in UTC with no spelling in a hybrid +tzinfo class. In US Eastern, that's 5:MM UTC = 0:MM EST = 1:MM EDT. During +that hour, on an Eastern clock 1:MM is taken as being in standard time (6:MM +UTC) because the docs insist on that, but 0:MM is taken as being in daylight +time (4:MM UTC). There is no local time mapping to 5:MM UTC. The local +clock jumps from 1:59 back to 1:00 again, and repeats the 1:MM hour in +standard time. Since that's what the local clock *does*, we want to map both +UTC hours 5:MM and 6:MM to 1:MM Eastern. The result is ambiguous +in local time, but so it goes -- it's the way the local clock works. + +When x = 5:MM UTC is the input to this algorithm, x.o=0, y.o=-5 and y.d=0, +so z=0:MM. z.d=60 (minutes) then, so [5] doesn't hold and we keep going. +z' = z + z.d = 1:MM then, and z'.d=0, and z'.d - z.d = -60 != 0 so [8] +(correctly) concludes that z' is not UTC-equivalent to x. + +Because we know z.d said z was in daylight time (else [5] would have held and +we would have stopped then), and we know z.d != z'.d (else [8] would have held +and we have stopped then), and there are only 2 possible values dst() can +return in Eastern, it follows that z'.d must be 0 (which it is in the example, +but the reasoning doesn't depend on the example -- it depends on there being +two possible dst() outcomes, one zero and the other non-zero). Therefore +z' must be in standard time, and is the spelling we want in this case. + +Note again that z' is not UTC-equivalent as far as the hybrid tzinfo class is +concerned (because it takes z' as being in standard time rather than the +daylight time we intend here), but returning it gives the real-life "local +clock repeats an hour" behavior when mapping the "unspellable" UTC hour into +tz. + +When the input is 6:MM, z=1:MM and z.d=0, and we stop at once, again with +the 1:MM standard time spelling we want. + +So how can this break? One of the assumptions must be violated. Two +possibilities: + +1) [2] effectively says that y.s is invariant across all y belong to a given + time zone. This isn't true if, for political reasons or continental drift, + a region decides to change its base offset from UTC. + +2) There may be versions of "double daylight" time where the tail end of + the analysis gives up a step too early. I haven't thought about that + enough to say. + +In any case, it's clear that the default fromutc() is strong enough to handle +"almost all" time zones: so long as the standard offset is invariant, it +doesn't matter if daylight time transition points change from year to year, or +if daylight time is skipped in some years; it doesn't matter how large or +small dst() may get within its bounds; and it doesn't even matter if some +perverse time zone returns a negative dst()). So a breaking case must be +pretty bizarre, and a tzinfo subclass can override fromutc() if it is. +""" +try: + from _datetime import * +except ImportError: + pass +else: + # Clean up unused names + del (_DAYNAMES, _DAYS_BEFORE_MONTH, _DAYS_IN_MONTH, + _DI100Y, _DI400Y, _DI4Y, _MAXORDINAL, _MONTHNAMES, + _build_struct_time, _call_tzinfo_method, _check_date_fields, + _check_time_fields, _check_tzinfo_arg, _check_tzname, + _check_utc_offset, _cmp, _cmperror, _date_class, _days_before_month, + _days_before_year, _days_in_month, _format_time, _is_leap, + _isoweek1monday, _math, _ord2ymd, _time, _time_class, _tzinfo_class, + _wrap_strftime, _ymd2ord) + # XXX Since import * above excludes names that start with _, + # docstring does not get overwritten.

Python 3 or Python 2. + +.. _forwards-conversion-text: + +Separating text from bytes +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +After applying stage 2, the recommended step is to decide which of your Python +2 strings represent text and which represent binary data and to prefix all +string literals with either ``b`` or ``u`` accordingly. Furthermore, to ensure +that these types behave similarly on Python 2 as on Python 3, also wrap +byte-strings or text in the ``bytes`` and ``str`` types from ``future``. For +example:: + + from future.builtins import bytes, str + b = bytes(b'\x00ABCD') + s = str(u'This is normal text') + +Any unadorned string literals will then represent native platform strings +(byte-strings on Py2, unicode strings on Py3). + +An alternative is to pass the ``--unicode_literals`` flag:: + + $ futurize --unicode_literals mypython2script.py + +After running this, all string literals that were not explicitly marked up as +``b''`` will mean text (Python 3 ``str`` or Python 2 ``unicode``). + + + +.. _forwards-conversion-stage3: + +Post-conversion +~~~~~~~~~~~~~~~ + +After running ``futurize``, we recommend first running your tests on Python 3 and making further code changes until they pass on Python 3. + +The next step would be manually tweaking the code to re-enable Python 2 +compatibility with the help of the ``future`` package. For example, you can add +the ``@python_2_unicode_compatible`` decorator to any classes that define custom +``__str__`` methods.

Therefore this code +is now possible on Python 2 and 3:: + + from future import standard_library + standard_library.install_hooks() + import http.client + standard_library.remove_hooks() + import requests + + data = requests.get('http://www.google.com') + + +Previously, this required manually removing ``http`` and ``http.client`` from +``sys.modules`` before importing ``requests`` on Python 2.x. (Issue #19). + +This change should also improve the compatibility of the standard library hooks +with any other module that provides its own Python 2/3 compatibility code. + +Note that the situation will improve further in version 0.12; import hooks will +require an explicit function call or the ``hooks`` context manager. + + +Conversion scripts explicitly install import hooks +-------------------------------------------------- + +The ``futurize`` and ``pasteurize`` scripts now add an explicit call to +``install_hooks()`` to install the standard library import hooks. These scripts +now add these two lines:: + + from future import standard_library + standard_library.install_hooks() + +instead of just the first one. The next major version of ``future`` (0.12) will +require the explicit call or use of the ``hooks`` context manager. This will +allow finer-grained control over whether import hooks are enabled for other +imported modules, such as ``requests``, which provide their own Python 2/3 +compatibility code. + + +``futurize`` script no longer adds ``unicode_literals`` by default +------------------------------------------------------------------ + +There is a new ``--unicode-literals`` flag to ``futurize`` that adds the +import:: + + from __future__ import unicode_literals + +to the top of each converted module. Without this flag, ``futurize`` now no +longer adds this import. (Issue #22). + +The ``pasteurize`` script for converting from Py3 to Py2/3 still adds +``unicode_literals``. (See the comments in issue #22 for an explanation.) + + +.. _whats-new-0.11: + +What's new in version 0.11 +========================== + +There are several major new features in version 0.11. + + +``past`` package +---------------- + +The python-future project now provides a ``past`` package in addition to the +``future`` package. Whereas ``future`` provides improved compatibility with +Python 3 code to Python 2, ``past`` provides support for using and interacting +with Python 2 code from Python 3. The structure reflects that of ``future``, +with ``past.builtins`` and ``past.utils``. There is also a new +``past.translation`` package that provides transparent translation of Python 2 +code to Python 3. (See below.) + +One purpose of ``past`` is to ease module-by-module upgrades to +codebases from Python 2. Another is to help with enabling Python 2 libraries to +support Python 3 without breaking the API they currently provide. (For example, +user code may expect these libraries to pass them Python 2's 8-bit strings, +rather than Python 3's ``bytes`` object.) A third purpose is to help migrate +projects to Python 3 even if one or more dependencies are still on Python 2. + +Currently ``past.builtins`` provides forward-ports of Python 2's ``str`` and +``dict`` objects, ``basestring``, and list-producing iterator functions. In +later releases, ``past.builtins`` will be used internally by the +``past.translation`` package to help with importing and using old Python 2 +modules in a Python 3 environment. + + +Auto-translation of Python 2 modules upon import +------------------------------------------------ + +``past`` provides an experimental ``translation`` package to help +with importing and using old Python 2 modules in a Python 3 environment. + +This is implemented using import hooks that attempt to automatically +translate Python 2 modules to Python 3 syntax and semantics upon import. Use +it like this:: + + $ pip3 install plotrique==0.2.5-7 --no-compile # to ignore SyntaxErrors + $ python3 + +Then pass in a whitelist of module name prefixes to the ``past.autotranslate()`` +function. Example:: + + >>> from past import autotranslate + >>> autotranslate(['plotrique']) + >>> import plotrique + + +This is intended to help you migrate to Python 3 without the need for all +your code's dependencies to support Python 3 yet. It should be used as a +last resort; ideally Python 2-only dependencies should be ported +properly to a Python 2/3 compatible codebase using a tool like +``futurize`` and the changes should be pushed to the upstream project. + +For more information, see :ref:`translation`. + + +Separate ``pasteurize`` script +------------------------------ + +The functionality from ``futurize --from3`` is now in a separate script called +``pasteurize``. Use ``pasteurize`` when converting from Python 3 code to Python +2/3 compatible source. For more information, see :ref:`backwards-conversion`. + + +pow() +----- + +There is now a ``pow()`` function in ``future.builtins.misc`` that behaves like +the Python 3 ``pow()`` function when raising a negative number to a fractional +power (returning a complex number). + + +input() no longer disabled globally on Py2 +------------------------------------------ + +Previous versions of ``future`` deleted the ``input()`` function from +``__builtin__`` on Python 2 as a security measure. This was because +Python 2's ``input()`` function allows arbitrary code execution and could +present a security vulnerability on Python 2 if someone expects Python 3 +semantics but forgets to import ``input`` from ``future.builtins``. This +behaviour has been reverted, in the interests of broadening the +compatibility of ``future`` with other Python 2 modules. + +Please remember to import ``input`` from ``future.builtins`` if you use +``input()`` in a Python 2/3 compatible codebase. + + +.. _deprecated-auto-import-hooks: + +Deprecated feature: auto-installation of standard-library import hooks +---------------------------------------------------------------------- + +Previous versions of ``python-future`` installed import hooks automatically upon +importing the ``standard_library`` module from ``future``. This has been +deprecated in order to improve robustness and compatibility with modules like +``requests`` that already perform their own single-source Python 2/3 +compatibility. + +As of v0.12 of ``python-future``, importing ``future.standard_library`` +will no longer install import hooks by default. Instead, please install the +import hooks explicitly as follows:: + + from future import standard_library + standard_library.install_hooks() + +and uninstall them after your import statements using:: + + standard_library.remove_hooks() + +*Note*: this will be a backward-incompatible change. + + + +Internal changes +---------------- + +The internal ``future.builtins.backports`` module has been renamed to +``future.builtins.types``. This will change the ``repr`` of ``future`` +types but not their use. + + +.. _whats-new-0.10.2: + +What's new in version 0.10.2 +============================ + + +.. Simpler imports +.. --------------- +.. +.. It is now possible to import builtins directly from the ``future`` +.. namespace as follows:: +.. +.. >>> from future import * +.. +.. or just those you need:: +.. +.. >>> from future import open, str + + +Utility functions for raising exceptions with a traceback portably +------------------------------------------------------------------ + +The functions ``raise_with_traceback()`` and ``raise_`` were added to +``future.utils`` to offer either the Python 3.x or Python 2.x behaviour +for raising exceptions. Thanks to Joel Tratner for the contribution of +these. + + +.. _whats-new-0.10: + +What's new in version 0.10 +========================== + +Backported ``dict`` type +------------------------ + +``future.builtins`` now provides a Python 2 ``dict`` subclass whose +:func:`keys`, :func:`values`, and :func:`items` methods produce +memory-efficient iterators. On Python 2.7, these also have the same set-like +view behaviour as on Python 3. This can streamline code needing to iterate +over large dictionaries. For example:: + + from __future__ import print_function + from future.builtins import dict, range + + squares = dict({i: i**2 for i in range(10**7)}) + + assert not isinstance(d.items(), list) + # Because items() is memory-efficient, so is this: + square_roots = dict((i_squared, i) for (i, i_squared) in squares.items()) + +For more information, see :ref:`dict-object`. + + +Refactoring of standard_library hooks (v0.10.2) +----------------------------------------------- + +There is a new context manager ``future.standard_library.hooks``. Use it like +this:: + + from future import standard_library + with standard_library.hooks(): + import queue + import configserver + from http.client import HTTPConnection + # etc. + +If not using this context manager, it is now encouraged to add an explicit call to +``standard_library.install_hooks()`` as follows:: + + from future import standard_library + standard_library.install_hooks() + + import queue + import html + import http.client + # etc. + +and to remove the hooks afterwards with:: + + standard_library.remove_hooks() + +The functions ``install_hooks()`` and ``remove_hooks()`` were previously +called ``enable_hooks()`` and ``disable_hooks()``. The old names are +still available as aliases, but are deprecated. + +As usual, this feature has no effect on Python 3. + + + +Utility functions raise_ and exec_ +---------------------------------- + +The functions ``raise_with_traceback()`` and ``raise_()`` were +added to ``future.utils`` to offer either the Python 3.x or Python 2.x +behaviour for raising exceptions. Thanks to Joel Tratner for the +contribution of these. ``future.utils.reraise()`` is now deprecated. + +A portable ``exec_()`` function has been added to ``future.utils`` from +``six``. + + +Bugfixes +-------- +- Fixed newint.__divmod__ +- Improved robustness of installing and removing import hooks in :mod:`future.standard_library` +- v0.10.1: Fixed broken ``pip install future`` on Py3 + + +.. _whats-new-0.9: + +What's new in version 0.9 +========================= + + +``isinstance`` checks supported natively with backported types +-------------------------------------------------------------- + +The ``isinstance`` function is no longer redefined in ``future.builtins`` +to operate with the backported ``int``, ``bytes`` and ``str``. +``isinstance`` checks with the backported types now work correctly by +default; we achieve this through overriding the ``__instancecheck__`` +method of metaclasses of the backported types. + +For more information, see :ref:`isinstance-calls`. + + +``futurize``: minimal imports by default +---------------------------------------- + +By default, the ``futurize`` script now only adds the minimal set of +imports deemed necessary. + +There is now an ``--all-imports`` option to the ``futurize`` script which +gives the previous behaviour, which is to add all ``__future__`` imports +and ``from future.builtins import *`` imports to every module. (This even +applies to an empty ``__init__.py`` file. + + +Looser type-checking for the backported ``str`` object +------------------------------------------------------ + +Now the ``future.builtins.str`` object behaves more like the Python 2 +``unicode`` object with regard to type-checking. This is to work around some +bugs / sloppiness in the Python 2 standard library involving mixing of +byte-strings and unicode strings, such as ``os.path.join`` in ``posixpath.py``. + +``future.builtins.str`` still raises the expected ``TypeError`` exceptions from +Python 3 when attempting to mix it with ``future.builtins.bytes``. + + +suspend_hooks() context manager added to ``future.standard_library`` +-------------------------------------------------------------------- + +Pychecker (as of v0.6.1)'s ``checker.py`` attempts to import the ``builtins`` +module as a way of determining whether Python 3 is running. Since this +succeeds when ``from future import standard_library`` is in effect, this +check does not work and pychecker sets the wrong value for its internal ``PY2`` +flag is set. + +To work around this, ``future`` now provides a context manager called +``suspend_hooks`` that can be used as follows:: + + from future import standard_library + ... + with standard_library.suspend_hooks(): + from pychecker.checker import Checker + + +.. _whats-new-0.8: + +What's new in version 0.8 +========================= + +Python 2.6 support +------------------ + +``future`` now includes support for Python 2.6. + +To run the ``future`` test suite on Python 2.6, this additional package is needed:: + + pip install unittest2 + +``http.server`` also requires the ``argparse`` package:: + + pip install argparse + + +Unused modules removed +---------------------- + +The ``future.six`` module has been removed. ``future`` doesn't require ``six`` +(and hasn't since version 0.3). If you need support for Python versions before +2.6, ``six`` is the best option. ``future`` and ``six`` can be installed +alongside each other easily if needed. + +The unused ``hacks`` module has also been removed from the source tree. + + +isinstance() added to :mod:`future.builtins` (v0.8.2) +----------------------------------------------------- + +It is now possible to use ``isinstance()`` calls normally after importing ``isinstance`` from +``future.builtins``. On Python 2, this is specially defined to be compatible with +``future``'s backported ``int``, ``str``, and ``bytes`` types, as well as +handling Python 2's int/long distinction. + +The result is that code that uses ``isinstance`` to perform type-checking of +ints, strings, and bytes should now work identically on Python 2 as on Python 3. + +The utility functions ``isint``, ``istext``, and ``isbytes`` provided before for +compatible type-checking across Python 2 and 3 in :mod:`future.utils` are now +deprecated. + + +.. _changelog: + +Summary of all changes +====================== + +v0.12.0: + * Add ``newobject`` and ``newlist`` types + * Improve compatibility of import hooks with Requests, py2exe + * No more auto-installation of import hooks by ``future.standard_library`` + * New ``future.moves`` package + * ``past.builtins`` improved + * ``newstr.encode(..., errors='surrogateescape')`` supported + * Refactoring: ``future.standard_library`` submodules -> ``future.backports`` + * Refactoring: ``future.builtins.types`` -> ``future.types`` + * Refactoring: ``past.builtins.types`` -> ``past.types`` + * New ``listvalues`` and ``listitems`` functions in ``future.utils`` + * Many bug fixes to ``futurize``, ``future.builtins``, etc. + +v0.11.4: + * Restore Py2.6 compatibility + +v0.11.3: + * The ``futurize`` and ``pasteurize`` scripts add an explicit call to + ``future.standard_library.install_hooks()`` whenever modules affected by PEP + 3108 are imported. + + * The ``future.builtins.bytes`` constructor now accepts ``frozenset`` + objects as on Py3. + +v0.11.2: + * The ``past.autotranslate`` feature now finds modules to import more + robustly and works with Python eggs. + +v0.11.1: + * Update to ``requirements_py26.txt`` for Python 2.6.

(Issue #19). - -This change should also improve the compatibility of the standard library hooks -with any other module that provides its own Python 2/3 compatibility code. - -Note that the situation will improve further in version 0.12; import hooks will -require an explicit function call or the ``hooks`` context manager. - - -Conversion scripts explicitly install import hooks --------------------------------------------------- - -The ``futurize`` and ``pasteurize`` scripts now add an explicit call to -``install_hooks()`` to install the standard library import hooks. These scripts -now add these two lines:: - - from future import standard_library - standard_library.install_hooks() - -instead of just the first one. The next major version of ``future`` (0.12) will -require the explicit call or use of the ``hooks`` context manager. This will -allow finer-grained control over whether import hooks are enabled for other -imported modules, such as ``requests``, which provide their own Python 2/3 -compatibility code. - - -``futurize`` script no longer adds ``unicode_literals`` by default ------------------------------------------------------------------- - -There is a new ``--unicode-literals`` flag to ``futurize`` that adds the -import:: - - from __future__ import unicode_literals - -to the top of each converted module. Without this flag, ``futurize`` now no -longer adds this import. (Issue #22). - -The ``pasteurize`` script for converting from Py3 to Py2/3 still adds -``unicode_literals``. (See the comments in issue #22 for an explanation.) - - -.. whats-new-0.11: - -What's new in version 0.11 -========================== - -There are several major new features in version 0.11. - - -``past`` package ----------------- - -The python-future project now provides a ``past`` package in addition to the -``future`` package. Whereas ``future`` provides improved compatibility with -Python 3 code to Python 2, ``past`` provides support for using and interacting -with Python 2 code from Python 3. The structure reflects that of ``future``, -with ``past.builtins`` and ``past.utils``. There is also a new -``past.translation`` package that provides transparent translation of Python 2 -code to Python 3. (See below.) - -One purpose of ``past`` is to ease module-by-module upgrades to -codebases from Python 2. Another is to help with enabling Python 2 libraries to -support Python 3 without breaking the API they currently provide. (For example, -user code may expect these libraries to pass them Python 2's 8-bit strings, -rather than Python 3's ``bytes`` object.) A third purpose is to help migrate -projects to Python 3 even if one or more dependencies are still on Python 2. - -Currently ``past.builtins`` provides forward-ports of Python 2's ``str`` and -``dict`` objects, ``basestring``, and list-producing iterator functions. In -later releases, ``past.builtins`` will be used internally by the -``past.translation`` package to help with importing and using old Python 2 -modules in a Python 3 environment. - - -Auto-translation of Python 2 modules upon import ------------------------------------------------- - -``past`` provides an experimental ``translation`` package to help -with importing and using old Python 2 modules in a Python 3 environment. - -This is implemented using import hooks that attempt to automatically -translate Python 2 modules to Python 3 syntax and semantics upon import. Use -it like this:: - - $ pip3 install plotrique==0.2.5-7 --no-compile # to ignore SyntaxErrors - $ python3 - -Then pass in a whitelist of module name prefixes to the ``past.autotranslate()`` -function. Example:: - - >>> from past import autotranslate - >>> autotranslate(['plotrique']) - >>> import plotrique - - -This is intended to help you migrate to Python 3 without the need for all -your code's dependencies to support Python 3 yet. It should be used as a -last resort; ideally Python 2-only dependencies should be ported -properly to a Python 2/3 compatible codebase using a tool like -``futurize`` and the changes should be pushed to the upstream project. - -For more information, see :ref:`translation`. - - -Separate ``pasteurize`` script ------------------------------- - -The functionality from ``futurize --from3`` is now in a separate script called -``pasteurize``. Use ``pasteurize`` when converting from Python 3 code to Python -2/3 compatible source. For more information, see :ref:`backwards-conversion`. - - -pow() ------ - -There is now a ``pow()`` function in ``future.builtins.misc`` that behaves like -the Python 3 ``pow()`` function when raising a negative number to a fractional -power (returning a complex number). - - -input() no longer disabled globally on Py2 ------------------------------------------- - -Previous versions of ``future`` deleted the ``input()`` function from -``__builtin__`` on Python 2 as a security measure. This was because -Python 2's ``input()`` function allows arbitrary code execution and could -present a security vulnerability on Python 2 if someone expects Python 3 -semantics but forgets to import ``input`` from ``future.builtins``. This -behaviour has been reverted, in the interests of broadening the -compatibility of ``future`` with other Python 2 modules. - -Please remember to import ``input`` from ``future.builtins`` if you use -``input()`` in a Python 2/3 compatible codebase. - - -.. deprecated-auto-import-hooks: - -Deprecated feature: auto-installation of standard-library import hooks ----------------------------------------------------------------------- - -Previous versions of ``python-future`` installed import hooks automatically upon -importing the ``standard_library`` module from ``future``. This has been -deprecated in order to improve robustness and compatibility with modules like -``requests`` that already perform their own single-source Python 2/3 -compatibility. - -As of v0.12 of ``python-future``, importing ``future.standard_library`` -will no longer install import hooks by default. Instead, please install the -import hooks explicitly as follows:: - - from future import standard_library - standard_library.install_hooks() - -and uninstall them after your import statements using:: - - standard_library.remove_hooks() - -*Note*: this will be a backward-incompatible change. - - - -Internal changes ----------------- - -The internal ``future.builtins.backports`` module has been renamed to -``future.builtins.types``. This will change the ``repr`` of ``future`` -types but not their use. - - -.. whats-new-0.10.2: - -What's new in version 0.10.2 -============================ - - -.. Simpler imports -.. --------------- -.. -.. It is now possible to import builtins directly from the ``future`` -.. namespace as follows:: -.. -.. >>> from future import * -.. -.. or just those you need:: -.. -.. >>> from future import open, str - - -Utility functions for raising exceptions with a traceback portably ------------------------------------------------------------------- - -The functions ``raise_with_traceback()`` and ``raise_`` were added to -``future.utils`` to offer either the Python 3.x or Python 2.x behaviour -for raising exceptions. Thanks to Joel Tratner for the contribution of -these. - - -.. whats-new-0.10: - -What's new in version 0.10 -========================== - -Backported ``dict`` type ------------------------- - -``future.builtins`` now provides a Python 2 ``dict`` subclass whose -:func:`keys`, :func:`values`, and :func:`items` methods produce -memory-efficient iterators. On Python 2.7, these also have the same set-like -view behaviour as on Python 3. This can streamline code needing to iterate -over large dictionaries. For example:: - - from __future__ import print_function - from future.builtins import dict, range - - squares = dict({i: i**2 for i in range(10**7)}) - - assert not isinstance(d.items(), list) - # Because items() is memory-efficient, so is this: - square_roots = dict((i_squared, i) for (i, i_squared) in squares.items()) - -For more information, see :ref:`dict-object`. - - -Refactoring of standard_library hooks (v0.10.2) ------------------------------------------------ - -There is a new context manager ``future.standard_library.hooks``. Use it like -this:: - - from future import standard_library - with standard_library.hooks(): - import queue - import configserver - from http.client import HTTPConnection - # etc. - -If not using this context manager, it is now encouraged to add an explicit call to -``standard_library.install_hooks()`` as follows:: - - from future import standard_library - standard_library.install_hooks() - - import queue - import html - import http.client - # etc. - -and to remove the hooks afterwards with:: - - standard_library.remove_hooks() - -The functions ``install_hooks()`` and ``remove_hooks()`` were previously -called ``enable_hooks()`` and ``disable_hooks()``. The old names are -still available as aliases, but are deprecated. - -As usual, this feature has no effect on Python 3. - - - -Utility functions raise_ and exec_ ----------------------------------- - -The functions ``raise_with_traceback()`` and ``raise_()`` were -added to ``future.utils`` to offer either the Python 3.x or Python 2.x -behaviour for raising exceptions. Thanks to Joel Tratner for the -contribution of these. ``future.utils.reraise()`` is now deprecated. - -A portable ``exec_()`` function has been added to ``future.utils`` from -``six``. - - -Bugfixes --------- -- Fixed newint.__divmod__ -- Improved robustness of installing and removing import hooks in :mod:`future.standard_library` -- v0.10.1: Fixed broken ``pip install future`` on Py3 - - -.. whats-new-0.9: - -What's new in version 0.9 -========================= - - -``isinstance`` checks supported natively with backported types --------------------------------------------------------------- - -The ``isinstance`` function is no longer redefined in ``future.builtins`` -to operate with the backported ``int``, ``bytes`` and ``str``. -``isinstance`` checks with the backported types now work correctly by -default; we achieve this through overriding the ``__instancecheck__`` -method of metaclasses of the backported types. - -For more information, see :ref:`isinstance-calls`. - - -``futurize``: minimal imports by default ----------------------------------------- - -By default, the ``futurize`` script now only adds the minimal set of -imports deemed necessary. - -There is now an ``--all-imports`` option to the ``futurize`` script which -gives the previous behaviour, which is to add all ``__future__`` imports -and ``from future.builtins import *`` imports to every module. (This even -applies to an empty ``__init__.py`` file. - - -Looser type-checking for the backported ``str`` object ------------------------------------------------------- - -Now the ``future.builtins.str`` object behaves more like the Python 2 -``unicode`` object with regard to type-checking. This is to work around some -bugs / sloppiness in the Python 2 standard library involving mixing of -byte-strings and unicode strings, such as ``os.path.join`` in ``posixpath.py``. - -``future.builtins.str`` still raises the expected ``TypeError`` exceptions from -Python 3 when attempting to mix it with ``future.builtins.bytes``. - - -suspend_hooks() context manager added to ``future.standard_library`` --------------------------------------------------------------------- - -Pychecker (as of v0.6.1)'s ``checker.py`` attempts to import the ``builtins`` -module as a way of determining whether Python 3 is running. Since this -succeeds when ``from future import standard_library`` is in effect, this -check does not work and pychecker sets the wrong value for its internal ``PY2`` -flag is set. - -To work around this, ``future`` now provides a context manager called -``suspend_hooks`` that can be used as follows:: - - from future import standard_library - ... - with standard_library.suspend_hooks(): - from pychecker.checker import Checker - - -.. whats-new-0.8: - -What's new in version 0.8 -========================= - -Python 2.6 support ------------------- - -``future`` now includes support for Python 2.6. - -To run the ``future`` test suite on Python 2.6, this additional package is needed:: - - pip install unittest2 - -``http.server`` also requires the ``argparse`` package:: - - pip install argparse - - -Unused modules removed ----------------------- - -The ``future.six`` module has been removed. ``future`` doesn't require ``six`` -(and hasn't since version 0.3). If you need support for Python versions before -2.6, ``six`` is the best option. ``future`` and ``six`` can be installed -alongside each other easily if needed. - -The unused ``hacks`` module has also been removed from the source tree. - - -isinstance() added to :mod:`future.builtins` (v0.8.2) ------------------------------------------------------ - -It is now possible to use ``isinstance()`` calls normally after importing ``isinstance`` from -``future.builtins``. On Python 2, this is specially defined to be compatible with -``future``'s backported ``int``, ``str``, and ``bytes`` types, as well as -handling Python 2's int/long distinction. - -The result is that code that uses ``isinstance`` to perform type-checking of -ints, strings, and bytes should now work identically on Python 2 as on Python 3. - -The utility functions ``isint``, ``istext``, and ``isbytes`` provided before for -compatible type-checking across Python 2 and 3 in :mod:`future.utils` are now -deprecated. - - -.. changelog: - -Summary of all changes -====================== - -What's new in version 0.11.x -============================ - -v0.11.4: - * Restore Py2.6 compatibility - -v0.11.3: - * The ``futurize`` and ``pasteurize`` scripts add an explicit call to - ``future.standard_library.install_hooks()`` whenever modules affected by PEP - 3108 are imported. - - * The ``future.builtins.bytes`` constructor now accepts ``frozenset`` - objects as on Py3. - -v0.11.2: - * The ``past.autotranslate`` feature now finds modules to import more - robustly and works with Python eggs. - -v0.11.1: - * Update to ``requirements_py26.txt`` for Python 2.6.
