This tool tries to be an (in-process) HTTP/1.1-compliant cache. It's not quite there yet, but it's probably good enough for most sites.

It also sets request.cached to True if serving a cached representation, and sets request.cacheable to False (so it doesn't get cached again).

Overview ======== Statistics about program operation are an invaluable monitoring and debugging tool. Unfortunately, the gathering and reporting of these critical values is usually ad-hoc. This package aims to add a centralized place for gathering statistical performance data, a structure for recording that data which provides for extrapolation of that data into more useful information, and a method of serving that data to both human investigators and monitoring software. Let's examine each of those in more detail. Data Gathering -------------- Just as Python's `logging` module provides a common importable for gathering and sending messages, performance statistics would benefit from a similar common mechanism, and one that does *not* require each package which wishes to collect stats to import a third-party module. Therefore, we choose to re-use the `logging` module by adding a `statistics` object to it. That `logging.statistics` object is a nested dict. It is not a custom class, because that would: 1. require libraries and applications to import a third-party module in order to participate 2. inhibit innovation in extrapolation approaches and in reporting tools, and 3. be slow. There are, however, some specifications regarding the structure of the dict.:: { +----"SQLAlchemy": { | "Inserts": 4389745, | "Inserts per Second": | lambda s: s["Inserts"] / (time() - s["Start"]), | C +---"Table Statistics": { | o | "widgets": {-----------+ N | l | "Rows": 1.3M, | Record a | l | "Inserts": 400, | m | e | },---------------------+ e | c | "froobles": { s | t | "Rows": 7845, p | i | "Inserts": 0, a | o | }, c | n +---}, e | "Slow Queries": | [{"Query": "SELECT * FROM widgets;", | "Processing Time": 47.840923343, | }, | ], +----}, } The `logging.statistics` dict has four levels. The topmost level is nothing more than a set of names to introduce modularity, usually along the lines of package names. If the SQLAlchemy project wanted to participate, for example, it might populate the item `logging.statistics['SQLAlchemy']`, whose value would be a second-layer dict we call a "namespace". Namespaces help multiple packages to avoid collisions over key names, and make reports easier to read, to boot. The maintainers of SQLAlchemy should feel free to use more than one namespace if needed (such as 'SQLAlchemy ORM'). Note that there are no case or other syntax constraints on the namespace names; they should be chosen to be maximally readable by humans (neither too short nor too long). Each namespace, then, is a dict of named statistical values, such as 'Requests/sec' or 'Uptime'. You should choose names which will look good on a report: spaces and capitalization are just fine. In addition to scalars, values in a namespace MAY be a (third-layer) dict, or a list, called a "collection". For example, the CherryPy :class:`StatsTool` keeps track of what each request is doing (or has most recently done) in a 'Requests' collection, where each key is a thread ID; each value in the subdict MUST be a fourth dict (whew!) of statistical data about each thread. We call each subdict in the collection a "record". Similarly, the :class:`StatsTool` also keeps a list of slow queries, where each record contains data about each slow query, in order. Values in a namespace or record may also be functions, which brings us to: Extrapolation ------------- The collection of statistical data needs to be fast, as close to unnoticeable as possible to the host program. That requires us to minimize I/O, for example, but in Python it also means we need to minimize function calls. So when you are designing your namespace and record values, try to insert the most basic scalar values you already have on hand. When it comes time to report on the gathered data, however, we usually have much more freedom in what we can calculate. Therefore, whenever reporting tools (like the provided :class:`StatsPage` CherryPy class) fetch the contents of `logging.statistics` for reporting, they first call `extrapolate_statistics` (passing the whole `statistics` dict as the only argument). This makes a deep copy of the statistics dict so that the reporting tool can both iterate over it and even change it without harming the original. But it also expands any functions in the dict by calling them. For example, you might have a 'Current Time' entry in the namespace with the value "lambda scope: time.time()". The "scope" parameter is the current namespace dict (or record, if we're currently expanding one of those instead), allowing you access to existing static entries. If you're truly evil, you can even modify more than one entry at a time. However, don't try to calculate an entry and then use its value in further extrapolations; the order in which the functions are called is not guaranteed. This can lead to a certain amount of duplicated work (or a redesign of your schema), but that's better than complicating the spec. After the whole thing has been extrapolated, it's time for: Reporting --------- The :class:`StatsPage` class grabs the `logging.statistics` dict, extrapolates it all, and then transforms it to HTML for easy viewing. Each namespace gets its own header and attribute table, plus an extra table for each collection. This is NOT part of the statistics specification; other tools can format how they like. You can control which columns are output and how they are formatted by updating StatsPage.formatting, which is a dict that mirrors the keys and nesting of `logging.statistics`. The difference is that, instead of data values, it has formatting values. Use None for a given key to indicate to the StatsPage that a given column should not be output. Use a string with formatting (such as '%.3f') to interpolate the value(s), or use a callable (such as lambda v: v.isoformat()) for more advanced formatting. Any entry which is not mentioned in the formatting dict is output unchanged. Monitoring ---------- Although the HTML output takes pains to assign unique id's to each with statistical data, you're probably better off fetching /cpstats/data, which outputs the whole (extrapolated) `logging.statistics` dict in JSON format. That is probably easier to parse, and doesn't have any formatting controls, so you get the "original" data in a consistently-serialized format. Note: there's no treatment yet for datetime objects. Try time.time() instead for now if you can. Nagios will probably thank you. Turning Collection Off ---------------------- It is recommended each namespace have an "Enabled" item which, if False, stops collection (but not reporting) of statistical data. Applications SHOULD provide controls to pause and resume collection by setting these entries to False or True, if present.

Then use 'parseAuthorization' to retrieve the 'auth_map' used in 'checkResponse'. To use 'checkResponse' you must have already verified the password associated with the 'username' key in 'auth_map' dict. Then you use the 'checkResponse' function to verify if the password matches the one sent by the client.

You need to edit your config file to use sessions. Here's an example:: [/] tools.sessions.on = True tools.sessions.storage_type = "file" tools.sessions.storage_path = "/home/site/sessions" tools.sessions.timeout = 60 This sets the session to be stored in files in the directory /home/site/sessions, and the session timeout to 60 minutes. If you omit ``storage_type`` the sessions will be saved in RAM. ``tools.sessions.on`` is the only required line for working sessions, the rest are optional. By default, the session ID is passed in a cookie, so the client's browser must have cookies enabled for your site. To set data for the current session, use ``cherrypy.session['fieldname'] = 'fieldvalue'``; to get data use ``cherrypy.session.get('fieldname')``. ================ Locking sessions ================ By default, the ``'locking'`` mode of sessions is ``'implicit'``, which means the session is locked early and unlocked late. Be mindful of this default mode for any requests that take a long time to process (streaming responses, expensive calculations, database lookups, API calls, etc), as other concurrent requests that also utilize sessions will hang until the session is unlocked. If you want to control when the session data is locked and unlocked, set ``tools.sessions.locking = 'explicit'``. Then call ``cherrypy.session.acquire_lock()`` and ``cherrypy.session.release_lock()``. Regardless of which mode you use, the session is guaranteed to be unlocked when the request is complete. ================= Expiring Sessions ================= You can force a session to expire with :func:`cherrypy.lib.sessions.expire`. Simply call that function at the point you want the session to expire, and it will cause the session cookie to expire client-side. =========================== Session Fixation Protection =========================== If CherryPy receives, via a request cookie, a session id that it does not recognize, it will reject that id and create a new one to return in the response cookie. This `helps prevent session fixation attacks `_. However, CherryPy "recognizes" a session id by looking up the saved session data for that id. Therefore, if you never save any session data, **you will get a new session id for every request**. ================ Sharing Sessions ================ If you run multiple instances of CherryPy (for example via mod_python behind Apache prefork), you most likely cannot use the RAM session backend, since each instance of CherryPy will have its own memory space. Use a different backend instead, and verify that all instances are pointing at the same file or db location. Alternately, you might try a load balancer which makes sessions "sticky". Google is your friend, there. ================ Expiration Dates ================ The response cookie will possess an expiration date to inform the client at which point to stop sending the cookie back in requests. If the server time and client time differ, expect sessions to be unreliable. **Make sure the system time of your server is accurate**. CherryPy defaults to a 60-minute session timeout, which also applies to the cookie which is sent to the client. Unfortunately, some versions of Safari ("4 public beta" on Windows XP at least) appear to have a bug in their parsing of the GMT expiration date--they appear to interpret the date as one hour in the past. Sixty minutes minus one hour is pretty close to zero, so you may experience this bug as a new session id for every request, unless the requests are less than one second apart. To fix, try increasing the session.timeout. On the other extreme, some users report Firefox sending cookies after their expiration date, although this was on a system with an inaccurate system time. Maybe FF doesn't trust system time.

This module is completely standalone, depending only on the stdlib. Web Site Process Bus -------------------- A Bus object is used to contain and manage site-wide behavior: daemonization, HTTP server start/stop, process reload, signal handling, drop privileges, PID file management, logging for all of these, and many more. In addition, a Bus object provides a place for each web framework to register code that runs in response to site-wide events (like process start and stop), or which controls or otherwise interacts with the site-wide components mentioned above. For example, a framework which uses file-based templates would add known template filenames to an autoreload component. Ideally, a Bus object will be flexible enough to be useful in a variety of invocation scenarios: 1. The deployer starts a site from the command line via a framework-neutral deployment script; applications from multiple frameworks are mixed in a single site. Command-line arguments and configuration files are used to define site-wide components such as the HTTP server, WSGI component graph, autoreload behavior, signal handling, etc. 2. The deployer starts a site via some other process, such as Apache; applications from multiple frameworks are mixed in a single site. Autoreload and signal handling (from Python at least) are disabled. 3. The deployer starts a site via a framework-specific mechanism; for example, when running tests, exploring tutorials, or deploying single applications from a single framework. The framework controls which site-wide components are enabled as it sees fit. The Bus object in this package uses topic-based publish-subscribe messaging to accomplish all this. A few topic channels are built in ('start', 'stop', 'exit', 'graceful', 'log', and 'main'). Frameworks and site containers are free to define their own. If a message is sent to a channel that has not been defined or has no listeners, there is no effect. In general, there should only ever be a single Bus object per process. Frameworks and site containers share a single Bus object by publishing messages and subscribing listeners. The Bus object works as a finite state machine which models the current state of the process. Bus methods move it from one state to another; those methods then publish to subscribed listeners on the channel for the new state.:: O | V STOPPING --> STOPPED --> EXITING -> X A A | | \___ | | \ | | V V STARTED <-- STARTING """ import atexit import os import sys import threading import time import traceback as _traceback import warnings from cherrypy._cpcompat import set # Here I save the value of os.getcwd(), which, if I am imported early enough, # will be the directory from which the startup script was run.

To autostart modwsgi, the "apache" executable or script must be on your system path, or you must override the global APACHE_PATH. On some platforms, "apache" may be called "apachectl" or "apache2ctl"-- create a symlink to them if needed. KNOWN BUGS ========== ##1. Apache processes Range headers automatically; CherryPy's truncated ## output is then truncated again by Apache. See test_core.testRanges. ## This was worked around in http://www.cherrypy.org/changeset/1319. 2. Apache does not allow custom HTTP methods like CONNECT as per the spec. See test_core.testHTTPMethods. 3. Max request header and body settings do not work with Apache. ##4. Apache replaces status "reason phrases" automatically. For example, ## CherryPy may set "304 Not modified" but Apache will write out ## "304 Not Modified" (capital "M"). ##5. Apache does not allow custom error codes as per the spec. ##6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the ## Request-URI too early. 7. mod_wsgi will not read request bodies which use the "chunked" transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and mod_python's requestobject.c). 8. When responding with 204 No Content, mod_wsgi adds a Content-Length header for you. 9. When an error is raised, mod_wsgi has no facility for printing a traceback as the response content (it's sent to the Apache log instead). 10. Startup and shutdown of Apache when running mod_wsgi seems slow.

A couple of notes: - Each of these tutorials builds on the ones before it. If you're new to CherryPy, we recommend you start with 01_helloworld.py and work your way upwards. :) - In most of these tutorials, you will notice that all output is done by returning normal Python strings, often using simple Python variable substitution. In most real-world applications, you will probably want to use a separate template package (like Cheetah, CherryTemplate or XML/XSL).

Using this mechanism you can easily simulate virtual URI structures by parsing the extra URI string, which you can access through cherrypy.request.virtualPath.

CherryPy will pass it to your exposed method as an argument (see "myFile" below); that arg will have a "file" attribute, which is a handle to the temporary uploaded file. If you wish to permanently save the file, you need to read() from myFile.file and write() somewhere else. Note the use of 'enctype="multipart/form-data"' and 'input type="file"' in the HTML which the client uses to upload the file. Downloads --------- If you wish to send a file to the client, you have two options: First, you can simply return a file-like object from your page handler. CherryPy will read the file and serve it as the content (HTTP body) of the response. However, that doesn't tell the client that the response is a file to be saved, rather than displayed. Use cherrypy.lib.static.serve_file for that; it takes four arguments: serve_file(path, content_type=None, disposition=None, name=None) Set "name" to the filename that you expect clients to use when they save your file. Note that the "name" argument is ignored if you don't also provide a "disposition" (usually "attachement"). You can manually set "content_type", but be aware that if you also use the encoding tool, it may choke if the file extension is not recognized as belonging to a known Content-Type. Setting the content_type to "application/x-download" works in most cases, and should prompt the user with an Open/Save dialog in popular browsers.

Each connection can consist of an arbitrary number of requests and their responses, so we run a nested loop:: while True: conn = server.requests.get() conn.communicate() -> while True: req = HTTPRequest(...) req.parse_request() -> # Read the Request-Line, e.g. "GET /page HTTP/1.1" req.rfile.readline() read_headers(req.rfile, req.inheaders) req.respond() -> response = app(...) try: for chunk in response: if chunk: req.write(chunk) finally: if hasattr(response, "close"): response.close() if req.close_connection: return """ __all__ = ['HTTPRequest', 'HTTPConnection', 'HTTPServer', 'SizeCheckWrapper', 'KnownLengthRFile', 'ChunkedRFile', 'CP_fileobject', 'MaxSizeExceeded', 'NoSSLError', 'FatalSSLAlert', 'WorkerThread', 'ThreadPool', 'SSLAdapter', 'CherryPyWSGIServer', 'Gateway', 'WSGIGateway', 'WSGIGateway_10', 'WSGIGateway_u0', 'WSGIPathInfoDispatcher', 'get_ssl_adapter_class'] import os try: import queue except: import Queue as queue import re import rfc822 import socket import sys if 'win' in sys.platform and hasattr(socket, "AF_INET6"): if not hasattr(socket, 'IPPROTO_IPV6'): socket.IPPROTO_IPV6 = 41 if not hasattr(socket, 'IPV6_V6ONLY'): socket.IPV6_V6ONLY = 27 try: import cStringIO as StringIO except ImportError: import StringIO DEFAULT_BUFFER_SIZE = -1 class FauxSocket(object): """Faux socket with the minimal interface required by pypy""" def _reuse(self): pass _fileobject_uses_str_type = isinstance( socket._fileobject(FauxSocket())._rbuf, basestring) del FauxSocket # this class is not longer required for anything. import threading import time import traceback def format_exc(limit=None): """Like print_exc() but return a string.

CherryPy 3.2 is compatible with Python versions 2.3+. This module provides a useful abstraction over the differences between Python versions, sometimes by preferring a newer idiom, sometimes an older one, and sometimes a custom one. In particular, Python 2 uses str and '' for byte strings, while Python 3 uses str and '' for unicode strings. We will call each of these the 'native string' type for each version. Because of this major difference, this module provides new 'bytestr', 'unicodestr', and 'nativestr' attributes, as well as two functions: 'ntob', which translates native strings (of type 'str') into byte strings regardless of Python version, and 'ntou', which translates native strings to unicode strings. This also provides a 'BytesIO' name for dealing specifically with bytes, and a 'StringIO' name for dealing with native strings. It also provides a 'base64_decode' function with native strings as input and output.

This module intends to replace several other, older modules and functions, like: os.system os.spawn* os.popen* popen2.* commands.* Information about how the subprocess module can be used to replace these modules and functions can be found below. Using the subprocess module =========================== This module defines one class called Popen: class Popen(args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startupinfo=None, creationflags=0): Arguments are: args should be a string, or a sequence of program arguments. The program to execute is normally the first item in the args sequence or string, but can be explicitly set by using the executable argument. On UNIX, with shell=False (default): In this case, the Popen class uses os.execvp() to execute the child program. args should normally be a sequence. A string will be treated as a sequence with the string as the only item (the program to execute). On UNIX, with shell=True: If args is a string, it specifies the command string to execute through the shell. If args is a sequence, the first item specifies the command string, and any additional items will be treated as additional shell arguments. On Windows: the Popen class uses CreateProcess() to execute the child program, which operates on strings. If args is a sequence, it will be converted to a string using the list2cmdline method. Please note that not all MS Windows applications interpret the command line the same way: The list2cmdline is designed for applications using the same rules as the MS C runtime. bufsize, if given, has the same meaning as the corresponding argument to the built-in open() function: 0 means unbuffered, 1 means line buffered, any other positive value means use a buffer of (approximately) that size. A negative bufsize means to use the system default, which usually means fully buffered. The default value for bufsize is 0 (unbuffered). stdin, stdout and stderr specify the executed programs' standard input, standard output and standard error file handles, respectively. Valid values are PIPE, an existing file descriptor (a positive integer), an existing file object, and None. PIPE indicates that a new pipe to the child should be created. With None, no redirection will occur; the child's file handles will be inherited from the parent. Additionally, stderr can be STDOUT, which indicates that the stderr data from the applications should be captured into the same file handle as for stdout. If preexec_fn is set to a callable object, this object will be called in the child process just before the child is executed. If close_fds is true, all file descriptors except 0, 1 and 2 will be closed before the child process is executed. if shell is true, the specified command will be executed through the shell. If cwd is not None, the current directory will be changed to cwd before the child is executed. If env is not None, it defines the environment variables for the new process. If universal_newlines is true, the file objects stdout and stderr are opened as a text files, but lines may be terminated by any of '\n', the Unix end-of-line convention, '\r', the Macintosh convention or '\r\n', the Windows convention. All of these external representations are seen as '\n' by the Python program. Note: This feature is only available if Python is built with universal newline support (the default). Also, the newlines attribute of the file objects stdout, stdin and stderr are not updated by the communicate() method. The startupinfo and creationflags, if given, will be passed to the underlying CreateProcess() function. They can specify things such as appearance of the main window and priority for the new process. (Windows only) This module also defines some shortcut functions: call(*popenargs, **kwargs): Run command with arguments. Wait for command to complete, then return the returncode attribute. The arguments are the same as for the Popen constructor. Example: retcode = call(["ls", "-l"]) check_call(*popenargs, **kwargs): Run command with arguments. Wait for command to complete. If the exit code was zero then return, otherwise raise CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute. The arguments are the same as for the Popen constructor. Example: check_call(["ls", "-l"]) check_output(*popenargs, **kwargs): Run command with arguments and return its output as a byte string. If the exit code was non-zero it raises a CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute and output in the output attribute. The arguments are the same as for the Popen constructor. Example: output = check_output(["ls", "-l", "/dev/null"]) Exceptions ---------- Exceptions raised in the child process, before the new program has started to execute, will be re-raised in the parent. Additionally, the exception object will have one extra attribute called 'child_traceback', which is a string containing traceback information from the childs point of view. The most common exception raised is OSError. This occurs, for example, when trying to execute a non-existent file. Applications should prepare for OSErrors. A ValueError will be raised if Popen is called with invalid arguments. check_call() and check_output() will raise CalledProcessError, if the called process returns a non-zero return code. Security -------- Unlike some other popen functions, this implementation will never call /bin/sh implicitly. This means that all characters, including shell metacharacters, can safely be passed to child processes. Popen objects ============= Instances of the Popen class have the following methods: poll() Check if child process has terminated. Returns returncode attribute. wait() Wait for child process to terminate. Returns returncode attribute. communicate(input=None) Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for process to terminate. The optional input argument should be a string to be sent to the child process, or None, if no data should be sent to the child. communicate() returns a tuple (stdout, stderr). Note: The data read is buffered in memory, so do not use this method if the data size is large or unlimited. The following attributes are also available: stdin If the stdin argument is PIPE, this attribute is a file object that provides input to the child process. Otherwise, it is None. stdout If the stdout argument is PIPE, this attribute is a file object that provides output from the child process. Otherwise, it is None. stderr If the stderr argument is PIPE, this attribute is file object that provides error output from the child process. Otherwise, it is None. pid The process ID of the child process. returncode The child return code. A None value indicates that the process hasn't terminated yet. A negative value -N indicates that the child was terminated by signal N (UNIX only). Replacing older functions with the subprocess module ==================================================== In this section, "a ==> b" means that b can be used as a replacement for a. Note: All functions in this section fail (more or less) silently if the executed program cannot be found; this module raises an OSError exception. In the following examples, we assume that the subprocess module is imported with "from subprocess import *". Replacing /bin/sh shell backquote --------------------------------- output=`mycmd myarg` ==> output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0] Replacing shell pipe line ------------------------- output=`dmesg | grep hda` ==> p1 = Popen(["dmesg"], stdout=PIPE) p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE) output = p2.communicate()[0] Replacing os.system() --------------------- sts = os.system("mycmd" + " myarg") ==> p = Popen("mycmd" + " myarg", shell=True) pid, sts = os.waitpid(p.pid, 0) Note: * Calling the program through the shell is usually not required. * It's easier to look at the returncode attribute than the exitstatus. A more real-world example would look like this: try: retcode = call("mycmd" + " myarg", shell=True) if retcode < 0: print >>sys.stderr, "Child was terminated by signal", -retcode else: print >>sys.stderr, "Child returned", retcode except OSError, e: print >>sys.stderr, "Execution failed:", e Replacing os.spawn* ------------------- P_NOWAIT example: pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg") ==> pid = Popen(["/bin/mycmd", "myarg"]).pid P_WAIT example: retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg") ==> retcode = call(["/bin/mycmd", "myarg"]) Vector example: os.spawnvp(os.P_NOWAIT, path, args) ==> Popen([path] + args[1:]) Environment example: os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env) ==> Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"}) Replacing os.popen* ------------------- pipe = os.popen("cmd", mode='r', bufsize) ==> pipe = Popen("cmd", shell=True, bufsize=bufsize, stdout=PIPE).stdout pipe = os.popen("cmd", mode='w', bufsize) ==> pipe = Popen("cmd", shell=True, bufsize=bufsize, stdin=PIPE).stdin (child_stdin, child_stdout) = os.popen2("cmd", mode, bufsize) ==> p = Popen("cmd", shell=True, bufsize=bufsize, stdin=PIPE, stdout=PIPE, close_fds=True) (child_stdin, child_stdout) = (p.stdin, p.stdout) (child_stdin, child_stdout, child_stderr) = os.popen3("cmd", mode, bufsize) ==> p = Popen("cmd", shell=True, bufsize=bufsize, stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True) (child_stdin, child_stdout, child_stderr) = (p.stdin, p.stdout, p.stderr) (child_stdin, child_stdout_and_stderr) = os.popen4("cmd", mode, bufsize) ==> p = Popen("cmd", shell=True, bufsize=bufsize, stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True) (child_stdin, child_stdout_and_stderr) = (p.stdin, p.stdout) On Unix, os.popen2, os.popen3 and os.popen4 also accept a sequence as the command to execute, in which case arguments will be passed directly to the program without shell intervention. This usage can be replaced as follows: (child_stdin, child_stdout) = os.popen2(["/bin/ls", "-l"], mode, bufsize) ==> p = Popen(["/bin/ls", "-l"], bufsize=bufsize, stdin=PIPE, stdout=PIPE) (child_stdin, child_stdout) = (p.stdin, p.stdout) Return code handling translates as follows: pipe = os.popen("cmd", 'w') ... rc = pipe.close() if rc is not None and rc % 256: print "There were some errors" ==> process = Popen("cmd", 'w', shell=True, stdin=PIPE) ... process.stdin.close() if process.wait() != 0: print "There were some errors" Replacing popen2.* ------------------ (child_stdout, child_stdin) = popen2.popen2("somestring", bufsize, mode) ==> p = Popen(["somestring"], shell=True, bufsize=bufsize stdin=PIPE, stdout=PIPE, close_fds=True) (child_stdout, child_stdin) = (p.stdout, p.stdin) On Unix, popen2 also accepts a sequence as the command to execute, in which case arguments will be passed directly to the program without shell intervention. This usage can be replaced as follows: (child_stdout, child_stdin) = popen2.popen2(["mycmd", "myarg"], bufsize, mode) ==> p = Popen(["mycmd", "myarg"], bufsize=bufsize, stdin=PIPE, stdout=PIPE, close_fds=True) (child_stdout, child_stdin) = (p.stdout, p.stdin) The popen2.Popen3 and popen2.Popen4 basically works as subprocess.Popen, except that: * subprocess.Popen raises an exception if the execution fails * the capturestderr argument is replaced with the stderr argument. * stdin=PIPE and stdout=PIPE must be specified. * popen2 closes all filedescriptors by default, but you have to specify close_fds=True with subprocess.Popen.

Configuration in CherryPy is implemented via dictionaries. Keys are strings which name the mapped value, which may be of any type. Architecture ------------ CherryPy Requests are part of an Application, which runs in a global context, and configuration data may apply to any of those three scopes: Global Configuration entries which apply everywhere are stored in cherrypy.config. Application Entries which apply to each mounted application are stored on the Application object itself, as 'app.config'. This is a two-level dict where each key is a path, or "relative URL" (for example, "/" or "/path/to/my/page"), and each value is a config dict. Usually, this data is provided in the call to tree.mount(root(), config=conf), although you may also use app.merge(conf). Request Each Request object possesses a single 'Request.config' dict. Early in the request process, this dict is populated by merging global config entries, Application entries (whose path equals or is a parent of Request.path_info), and any config acquired while looking up the page handler (see next). Declaration ----------- Configuration data may be supplied as a Python dictionary, as a filename, or as an open file object. When you supply a filename or file, CherryPy uses Python's builtin ConfigParser; you declare Application config by writing each path as a section header:: [/path/to/my/page] request.stream = True To declare global configuration entries, place them in a [global] section. You may also declare config entries directly on the classes and methods (page handlers) that make up your CherryPy application via the ``_cp_config`` attribute. For example:: class Demo: _cp_config = {'tools.gzip.on': True} def index(self): return "Hello world" index.exposed = True index._cp_config = {'request.show_tracebacks': False} .. note:: This behavior is only guaranteed for the default dispatcher. Other dispatchers may have different restrictions on where you can attach _cp_config attributes. Namespaces ---------- Configuration keys are separated into namespaces by the first "." in the key. Current namespaces: engine Controls the 'application engine', including autoreload. These can only be declared in the global config. tree Grafts cherrypy.Application objects onto cherrypy.tree. These can only be declared in the global config. hooks Declares additional request-processing functions. log Configures the logging for each application. These can only be declared in the global or / config. request Adds attributes to each Request. response Adds attributes to each Response. server Controls the default HTTP server via cherrypy.server. These can only be declared in the global config. tools Runs and configures additional request-processing packages. wsgi Adds WSGI middleware to an Application's "pipeline". These can only be declared in the app's root config ("/"). checker Controls the 'checker', which looks for common errors in app state (including config) when the engine starts. Global config only. The only key that does not exist in a namespace is the "environment" entry. This special entry 'imports' other config entries from a template stored in cherrypy._cpconfig.environments[environment]. It only applies to the global config, and only when you use cherrypy.config.update. You can define your own namespaces to be called at the Global, Application, or Request level, by adding a named handler to cherrypy.config.namespaces, app.namespaces, or app.request_class.namespaces. The name can be any string, and the handler must be either a callable or a (Python 2.5 style) context manager.

CherryPy provides (and uses) exceptions for declaring that the HTTP response should be a status other than the default "200 OK". You can ``raise`` them like normal Python exceptions. You can also call them and they will raise themselves; this means you can set an :class:`HTTPError` or :class:`HTTPRedirect` as the :attr:`request.handler`. .. _redirectingpost: Redirecting POST ================ When you GET a resource and are redirected by the server to another Location, there's generally no problem since GET is both a "safe method" (there should be no side-effects) and an "idempotent method" (multiple calls are no different than a single call). POST, however, is neither safe nor idempotent--if you charge a credit card, you don't want to be charged twice by a redirect! For this reason, *none* of the 3xx responses permit a user-agent (browser) to resubmit a POST on redirection without first confirming the action with the user: ===== ================================= =========== 300 Multiple Choices Confirm with the user 301 Moved Permanently Confirm with the user 302 Found (Object moved temporarily) Confirm with the user 303 See Other GET the new URI--no confirmation 304 Not modified (for conditional GET only--POST should not raise this error) 305 Use Proxy Confirm with the user 307 Temporary Redirect Confirm with the user ===== ================================= =========== However, browsers have historically implemented these restrictions poorly; in particular, many browsers do not force the user to confirm 301, 302 or 307 when redirecting POST. For this reason, CherryPy defaults to 303, which most user-agents appear to have implemented correctly. Therefore, if you raise HTTPRedirect for a POST request, the user-agent will most likely attempt to GET the new URI (without asking for confirmation from the user). We realize this is confusing for developers, but it's the safest thing we could do. You are of course free to raise ``HTTPRedirect(uri, status=302)`` or any other 3xx status if you know what you're doing, but given the environment, we couldn't let any of those be the default. Custom Error Handling ===================== .. image:: /refman/cperrors.gif Anticipated HTTP responses -------------------------- The 'error_page' config namespace can be used to provide custom HTML output for expected responses (like 404 Not Found). Supply a filename from which the output will be read. The contents will be interpolated with the values %(status)s, %(message)s, %(traceback)s, and %(version)s using plain old Python `string formatting `_. :: _cp_config = { 'error_page.404': os.path.join(localDir, "static/index.html") } Beginning in version 3.1, you may also provide a function or other callable as an error_page entry. It will be passed the same status, message, traceback and version arguments that are interpolated into templates:: def error_page_402(status, message, traceback, version): return "Error %s - Well, I'm very sorry but you haven't paid!" % status cherrypy.config.update({'error_page.402': error_page_402}) Also in 3.1, in addition to the numbered error codes, you may also supply "error_page.default" to handle all codes which do not have their own error_page entry. Unanticipated errors -------------------- CherryPy also has a generic error handling mechanism: whenever an unanticipated error occurs in your code, it will call :func:`Request.error_response` to set the response status, headers, and body. By default, this is the same output as :class:`HTTPError(500) `. If you want to provide some other behavior, you generally replace "request.error_response". Here is some sample code that shows how to display a custom error message and send an e-mail containing the error:: from cherrypy import _cperror def handle_error(): cherrypy.response.status = 500 cherrypy.response.body = [ "Sorry, an error occured" ] sendMail('error@domain.com', 'Error in your web app', _cperror.format_exc()) class Root: _cp_config = {'request.error_response': handle_error} Note that you have to explicitly set :attr:`response.body ` and not simply return an error message as a result.

"Simple" logging means that you can log to the screen (i.e. console/stdout) or to a file, and that you can easily have separate error and access log files. Here are the simplified logging settings. You use these by adding lines to your config file or dict. You should set these at either the global level or per application (see next), but generally not both. * ``log.screen``: Set this to True to have both "error" and "access" messages printed to stdout. * ``log.access_file``: Set this to an absolute filename where you want "access" messages written. * ``log.error_file``: Set this to an absolute filename where you want "error" messages written. Many events are automatically logged; to log your own application events, call :func:`cherrypy.log`. Architecture ============ Separate scopes --------------- CherryPy provides log managers at both the global and application layers. This means you can have one set of logging rules for your entire site, and another set of rules specific to each application. The global log manager is found at :func:`cherrypy.log`, and the log manager for each application is found at :attr:`app.log`. If you're inside a request, the latter is reachable from ``cherrypy.request.app.log``; if you're outside a request, you'll have to obtain a reference to the ``app``: either the return value of :func:`tree.mount()` or, if you used :func:`quickstart()` instead, via ``cherrypy.tree.apps['/']``. By default, the global logs are named "cherrypy.error" and "cherrypy.access", and the application logs are named "cherrypy.error.2378745" and "cherrypy.access.2378745" (the number is the id of the Application object). This means that the application logs "bubble up" to the site logs, so if your application has no log handlers, the site-level handlers will still log the messages. Errors vs. Access ----------------- Each log manager handles both "access" messages (one per HTTP request) and "error" messages (everything else). Note that the "error" log is not just for errors! The format of access messages is highly formalized, but the error log isn't--it receives messages from a variety of sources (including full error tracebacks, if enabled). If you are logging the access log and error log to the same source, then there is a possibility that a specially crafted error message may replicate an access log message as described in CWE-117. In this case it is the application developer's responsibility to manually escape data before using CherryPy's log() functionality, or they may create an application that is vulnerable to CWE-117. This would be achieved by using a custom handler escape any special characters, and attached as described below. Custom Handlers =============== The simple settings above work by manipulating Python's standard :mod:`logging` module. So when you need something more complex, the full power of the standard module is yours to exploit. You can borrow or create custom handlers, formats, filters, and much more. Here's an example that skips the standard FileHandler and uses a RotatingFileHandler instead: :: #python log = app.log # Remove the default FileHandlers if present. log.error_file = "" log.access_file = "" maxBytes = getattr(log, "rot_maxBytes", 10000000) backupCount = getattr(log, "rot_backupCount", 1000) # Make a new RotatingFileHandler for the error log. fname = getattr(log, "rot_error_file", "error.log") h = handlers.RotatingFileHandler(fname, 'a', maxBytes, backupCount) h.setLevel(DEBUG) h.setFormatter(_cplogging.logfmt) log.error_log.addHandler(h) # Make a new RotatingFileHandler for the access log. fname = getattr(log, "rot_access_file", "access.log") h = handlers.RotatingFileHandler(fname, 'a', maxBytes, backupCount) h.setLevel(DEBUG) h.setFormatter(_cplogging.logfmt) log.access_log.addHandler(h) The ``rot_*`` attributes are pulled straight from the application log object. Since "log.*" config entries simply set attributes on the log object, you can add custom attributes to your heart's content. Note that these handlers are used ''instead'' of the default, simple handlers outlined above (so don't set the "log.error_file" config entry, for example).

In short, :attr:`cherrypy.request.body` is now always set to an instance of :class:`RequestBody`, and *that* class is a subclass of :class:`Entity`. When an HTTP request includes an entity body, it is often desirable to provide that information to applications in a form other than the raw bytes. Different content types demand different approaches. Examples: * For a GIF file, we want the raw bytes in a stream. * An HTML form is better parsed into its component fields, and each text field decoded from bytes to unicode. * A JSON body should be deserialized into a Python dict or list. When the request contains a Content-Type header, the media type is used as a key to look up a value in the :attr:`request.body.processors` dict. If the full media type is not found, then the major type is tried; for example, if no processor is found for the 'image/jpeg' type, then we look for a processor for the 'image' types altogether. If neither the full type nor the major type has a matching processor, then a default processor is used (:func:`default_proc`). For most types, this means no processing is done, and the body is left unread as a raw byte stream. Processors are configurable in an 'on_start_resource' hook. Some processors, especially those for the 'text' types, attempt to decode bytes to unicode. If the Content-Type request header includes a 'charset' parameter, this is used to decode the entity. Otherwise, one or more default charsets may be attempted, although this decision is up to each processor. If a processor successfully decodes an Entity or Part, it should set the :attr:`charset` attribute on the Entity or Part to the name of the successful charset, so that applications can easily re-encode or transcode the value if they wish. If the Content-Type of the request entity is of major type 'multipart', then the above parsing process, and possibly a decoding process, is performed for each part. For both the full entity and multipart parts, a Content-Disposition header may be used to fill :attr:`name` and :attr:`filename` attributes on the request.body or the Part. .. _custombodyprocessors: Custom Processors ================= You can add your own processors for any specific or major MIME type. Simply add it to the :attr:`processors` dict in a hook/tool that runs at ``on_start_resource`` or ``before_request_body``. Here's the built-in JSON tool for an example:: def json_in(force=True, debug=False): request = cherrypy.serving.request def json_processor(entity): \"""Read application/json data into request.json.\""" if not entity.headers.get("Content-Length", ""): raise cherrypy.HTTPError(411) body = entity.fp.read() try: request.json = json_decode(body) except ValueError: raise cherrypy.HTTPError(400, 'Invalid JSON document') if force: request.body.processors.clear() request.body.default_proc = cherrypy.HTTPError( 415, 'Expected an application/json content type') request.body.processors['application/json'] = json_processor We begin by defining a new ``json_processor`` function to stick in the ``processors`` dictionary. All processor functions take a single argument, the ``Entity`` instance they are to process. It will be called whenever a request is received (for those URI's where the tool is turned on) which has a ``Content-Type`` of "application/json". First, it checks for a valid ``Content-Length`` (raising 411 if not valid), then reads the remaining bytes on the socket. The ``fp`` object knows its own length, so it won't hang waiting for data that never arrives. It will return when all data has been read. Then, we decode those bytes using Python's built-in ``json`` module, and stick the decoded result onto ``request.json`` . If it cannot be decoded, we raise 400. If the "force" argument is True (the default), the ``Tool`` clears the ``processors`` dict so that request entities of other ``Content-Types`` aren't parsed at all. Since there's no entry for those invalid MIME types, the ``default_proc`` method of ``cherrypy.request.body`` is called. But this does nothing by default (usually to provide the page handler an opportunity to handle it.) But in our case, we want to raise 415, so we replace ``request.body.default_proc`` with the error (``HTTPError`` instances, when called, raise themselves). If we were defining a custom processor, we can do so without making a ``Tool``. Just add the config entry:: request.body.processors = {'application/json': json_processor} Note that you can only replace the ``processors`` dict wholesale this way, not update the existing one.

This class collects information about the HTTP request entity. When a given entity is of MIME type "multipart", each part is parsed into its own Entity instance, and the set of parts stored in :attr:`entity.parts`. Between the ``before_request_body`` and ``before_handler`` tools, CherryPy tries to process the request body (if any) by calling :func:`request.body.process`. This uses the ``content_type`` of the Entity to look up a suitable processor in :attr:`Entity.processors`, a dict. If a matching processor cannot be found for the complete Content-Type, it tries again using the major type. For example, if a request with an entity of type "image/jpeg" arrives, but no processor can be found for that complete type, then one is sought for the major type "image". If a processor is still not found, then the :func:`default_proc` method of the Entity is called (which does nothing by default; you can override this too). CherryPy includes processors for the "application/x-www-form-urlencoded" type, the "multipart/form-data" type, and the "multipart" major type. CherryPy 3.2 processes these types almost exactly as older versions. Parts are passed as arguments to the page handler using their ``Content-Disposition.name`` if given, otherwise in a generic "parts" argument. Each such part is either a string, or the :class:`Part` itself if it's a file. (In this case it will have ``file`` and ``filename`` attributes, or possibly a ``value`` attribute). Each Part is itself a subclass of Entity, and has its own ``process`` method and ``processors`` dict. There is a separate processor for the "multipart" major type which is more flexible, and simply stores all multipart parts in :attr:`request.body.parts`.

Depending on the version of Python you're using, there may be a faster one available. You should always import the local class from threading.) Thread-local objects support the management of thread-local data. If you have data that you want to be local to a thread, simply create a thread-local object and use its attributes: >>> mydata = local() >>> mydata.number = 42 >>> mydata.number 42 You can also access the local-object's dictionary: >>> mydata.__dict__ {'number': 42} >>> mydata.__dict__.setdefault('widgets', []) [] >>> mydata.widgets [] What's important about thread-local objects is that their data are local to a thread. If we access the data in a different thread: >>> log = [] >>> def f(): ... items = mydata.__dict__.items() ... items.sort() ... log.append(items) ... mydata.number = 11 ... log.append(mydata.number) >>> import threading >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[], 11] we get different data. Furthermore, changes made in the other thread don't affect data seen in this thread: >>> mydata.number 42 Of course, values you get from a local object, including a __dict__ attribute, are for whatever thread was current at the time the attribute was read. For that reason, you generally don't want to save these values across threads, as they apply only to the thread they came from. You can create custom local objects by subclassing the local class: >>> class MyLocal(local): ... number = 2 ... initialized = False ... def __init__(self, **kw): ... if self.initialized: ... raise SystemError('__init__ called too many times') ... self.initialized = True ... self.__dict__.update(kw) ... def squared(self): ... return self.number ** 2 This can be useful to support default values, methods and initialization. Note that if you define an __init__ method, it will be called each time the local object is used in a separate thread. This is necessary to initialize each thread's dictionary. Now if we create a local object: >>> mydata = MyLocal(color='red') Now we have a default number: >>> mydata.number 2 an initial color: >>> mydata.color 'red' >>> del mydata.color And a method that operates on the data: >>> mydata.squared() 4 As before, we can access the data in a separate thread: >>> log = [] >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[('color', 'red'), ('initialized', True)], 11] without affecting this thread's data: >>> mydata.number 2 >>> mydata.color Traceback (most recent call last): ... AttributeError: 'MyLocal' object has no attribute 'color' Note that subclasses can define slots, but they are not thread local. They are shared across threads: >>> class MyLocal(local): ... __slots__ = 'number' >>> mydata = MyLocal() >>> mydata.number = 42 >>> mydata.color = 'red' So, the separate thread: >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() affects what we see: >>> mydata.number 11 >>> del mydata """ # Threading import is at end class _localbase(object): __slots__ = '_local__key', '_local__args', '_local__lock' def __new__(cls, *args, **kw): self = object.__new__(cls) key = 'thread.local.' + str(id(self)) object.__setattr__(self, '_local__key', key) object.__setattr__(self, '_local__args', (args, kw)) object.__setattr__(self, '_local__lock', RLock()) if args or kw and (cls.__init__ is object.__init__): raise TypeError("Initialization arguments are not supported") # We need to create the thread dict in anticipation of # __init__ being called, to make sure we don't call it # again ourselves. dict = object.__getattribute__(self, '__dict__') currentThread().__dict__[key] = dict return self def _patch(self): key = object.__getattribute__(self, '_local__key') d = currentThread().__dict__.get(key) if d is None: d = {} currentThread().__dict__[key] = d object.__setattr__(self, '__dict__', d) # we have a new instance dict, so call out __init__ if we have # one cls = type(self) if cls.__init__ is not object.__init__: args, kw = object.__getattribute__(self, '_local__args') cls.__init__(self, *args, **kw) else: object.__setattr__(self, '__dict__', d) class local(_localbase): def __getattribute__(self, name): lock = object.__getattribute__(self, '_local__lock') lock.acquire() try: _patch(self) return object.__getattribute__(self, name) finally: lock.release() def __setattr__(self, name, value): lock = object.__getattribute__(self, '_local__lock') lock.acquire() try: _patch(self) return object.__setattr__(self, name, value) finally: lock.release() def __delattr__(self, name): lock = object.__getattribute__(self, '_local__lock') lock.acquire() try: _patch(self) return object.__delattr__(self, name) finally: lock.release() def __del__(): threading_enumerate = enumerate __getattribute__ = object.__getattribute__ def __del__(self): key = __getattribute__(self, '_local__key') try: threads = list(threading_enumerate()) except: # if enumerate fails, as it seems to do during # shutdown, we'll skip cleanup under the assumption # that there is nothing to clean up return for thread in threads: try: __dict__ = thread.__dict__ except AttributeError: # Thread is dying, rest in peace continue if key in __dict__: try: del __dict__[key] except KeyError: pass # didn't have anything in this thread return __del__ __del__ = __del__() from threading import currentThread, enumerate, RLock CherryPy-3.5.0/cherrypy/_cptools.py0000666000000000000000000004522112353352346015471 0ustar 00000000000000"""CherryPy tools.

CherryPy consists of not one, but four separate API layers. The APPLICATION LAYER is the simplest. CherryPy applications are written as a tree of classes and methods, where each branch in the tree corresponds to a branch in the URL path. Each method is a 'page handler', which receives GET and POST params as keyword arguments, and returns or yields the (HTML) body of the response. The special method name 'index' is used for paths that end in a slash, and the special method name 'default' is used to handle multiple paths via a single handler. This layer also includes: * the 'exposed' attribute (and cherrypy.expose) * cherrypy.quickstart() * _cp_config attributes * cherrypy.tools (including cherrypy.session) * cherrypy.url() The ENVIRONMENT LAYER is used by developers at all levels. It provides information about the current request and response, plus the application and server environment, via a (default) set of top-level objects: * cherrypy.request * cherrypy.response * cherrypy.engine * cherrypy.server * cherrypy.tree * cherrypy.config * cherrypy.thread_data * cherrypy.log * cherrypy.HTTPError, NotFound, and HTTPRedirect * cherrypy.lib The EXTENSION LAYER allows advanced users to construct and share their own plugins. It consists of: * Hook API * Tool API * Toolbox API * Dispatch API * Config Namespace API Finally, there is the CORE LAYER, which uses the core API's to construct the default components which are available at higher layers. You can think of the default components as the 'reference implementation' for CherryPy. Megaframeworks (and advanced users) may replace the default components with customized or extended components. The core API's are: * Application API * Engine API * Request API * Server API * WSGI API These API's are described in the `CherryPy specification `_.
