Build all modules that are listed as shared in Modules/Setup. +# 3. Invoke setup.py. That builds all modules that +# a) are not builtin, and +# b) are not listed in Modules/Setup, and +# c) can be build on the target +# +# Therefore, modules declared to be shared will not be +# included in the config.c file, nor in the list of objects to be +# added to the library archive, and their linker options won't be +# added to the linker options.

This module +intends to replace several older modules and functions: + +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 child's 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.
