Here is an example of Pexpect in action:</p> -<blockquote> - <pre class="code"># This connects to the openbsd ftp site and<br># downloads the recursive directory listing.<br>import pexpect<br>child = pexpect.spawn ('ftp ftp.openbsd.org')<br>child.expect ('Name .*: ')<br>child.sendline ('anonymous')<br>child.expect ('Password:')<br>child.sendline ('noah@example.com')<br>child.expect ('ftp> ')<br>child.sendline ('cd pub')<br>child.expect('ftp> ')<br>child.sendline ('get ls-lR.gz')<br>child.expect('ftp> ')<br>child.sendline ('bye')<br></pre> -</blockquote> -<p> Obviously you could write an ftp client using Python's own <span - class="code">ftplib</span> module, but this is just a demonstration. -You can use this technique with any application. This is especially -handy if you are writing automated test tools.</p> - -<p>There are two important methods in Pexpect -- <span class="code"><b>expect()</b></span> -and <span class="code"><b>send()</b></span> (or <span class="code">sendline()</span> -which is like <span class="code">send()</span> with a linefeed). -The <span class="code">expect()</span> method waits for the child application -to return a given string. The string you specify is a regular expression, so -you can match complicated patterns. The <span class="code"><b>send()</b></span> method -writes a string to the child application. From the child's point of -view it looks just like someone typed the text from a terminal. After -each call to <span class="code"><b>expect()</b></span> the <span - class="code"><b>before</b></span> and <span class="code"><b>after</b></span> -properties will be set to the text printed by child application. The <span - class="code"><b>before</b></span> property will contain all text up to -the expected string pattern. The <span class="code"><b>after</b></span> string -will contain the text that was matched by the expected pattern. -The <span class="code">match</span> property is set to the <span class="code">re MatchObject</span>. -</p> - -<p>An example of Pexpect in action may make things more clear. This example uses -<span class="code">ftp</span> to login to the OpenBSD site; list files -in a directory; and then pass interactive control of the ftp session to -the human user.</p> -<blockquote> - <pre class="code">import pexpect<br>child = pexpect.spawn ('ftp ftp.openbsd.org')<br>child.expect ('Name .*: ')<br>child.sendline ('anonymous')<br>child.expect ('Password:')<br>child.sendline ('noah@example.com')<br>child.expect ('ftp> ')<br>child.sendline ('ls /pub/OpenBSD/')<br>child.expect ('ftp> ')<br>print child.before # Print the result of the ls command.<br>child.interact() # Give control of the child to the user.<br></pre> -</blockquote> -<h2>Special EOF and TIMEOUT patterns</h2> -<p> -There are two special patterns to match the End Of File or a Timeout condition. -You you can pass these patterns to <span class="code">expect()</span>. -These patterns are not regular expressions. Use them like predefined constants. -</p> -<p>If the child has died and you have read all the child's output then ordinarily -<span class="code">expect()</span> will raise an <span class="code">EOF</span> -exception. You can read everything up to the EOF without generating an -exception by using the EOF pattern <span class="code">expect(pexpect.EOF)</span>. -In this case everything the child has output will be available in the <span - class="code">before</span> property.</p> -<p>The pattern given to <span class="code">expect()</span> may be a -regular expression or it may also be a <b>list</b> of regular expressions. -This allows you to match multiple optional responses. The <span class="code">expect()</span> -method returns the index of the pattern that was matched. For example, -say you wanted to login to a server. After entering a password you -could get various responses from the server -- your password could be -rejected; or you could be allowed in and asked for your terminal type; -or you could be let right in and given a command prompt. The following -code fragment gives an example of this:</p> -<blockquote> - <pre class="code">child.expect('password:')<br>child.sendline (my_secret_password)<br># We expect any of these three patterns...<br>i = child.expect (['Permission denied', 'Terminal type', '[#\$] '])<br>if i==0:<br> print 'Permission denied on host.

The default time is 30 seconds, but you can -change this by passing a timeout argument to expect():</p> -<blockquote> - <pre class="code"># Wait no more than 2 minutes (120 seconds) for password prompt.<br>child.expect('password:', timeout=120)</pre> -</blockquote> -<h2>Find the end of line -- CR/LF conventions<br> -Matching at the end of a line can be tricky<br> -$ regex pattern is useless.<br> -</h2> -<p>Pexpect matches regular expressions a little differently than what -you might be used to. -</p> -<p><i><b>The $ pattern for end of line match is useless</b></i>. -The $ matches the end of string, but Pexpect reads from the child -one character at a time, so each character looks like the end of a line. -Pexpect can't do a look-ahead into the child's output stream. -In general you would have this situation when using regular expressions -with any stream.<br> -<i>Note, pexpect does have an internal buffer, so reads are faster -than one character at a time, but from the user's perspective the regex -patterns test happens one character at a time.</i></p> -<p>The best way to match the end of a line is to look for the -newline: "\r\n" (CR/LF). Yes, that does appear to be DOS-style. -It may surprise some UNIX people to learn that terminal TTY device drivers -(dumb, vt100, ANSI, xterm, etc.) all use the CR/LF combination to signify -the end of line. Pexpect uses a Pseudo-TTY device to talk to the child application, so -when the child app prints "\n" you actually see "\r\n". -</p> -<p><b>UNIX uses just linefeeds to end lines of text, but not when it -comes to TTY devices!</b> TTY devices are more like the Windows world. -Each line of text end with a CR/LF combination. When you intercept data -from a UNIX command from a TTY device you will find that the TTY device -outputs a CR/LF combination. A UNIX command may only write a linefeed -(\n), but the TTY device driver converts it to CR/LF. This means that -your terminal will see lines end with CR/LF (hex <span class="code">0D 0A</span>). -Since Pexpect emulates a terminal, to match ends of lines you have to -expect the CR/LF combination.</p> -<blockquote> - <p class="code">child.expect ('\r\n')</p> -</blockquote> -<p>If you just need to skip past a new line then <span class="code">expect -('\n')</span> by itself will work, but if you are expecting a specific -pattern before the end of line then you need to explicitly look for the -\r. For example the following expects a word at the end of a line:</p> -<blockquote> - <p class="code">child.expect ('\w+\r\n')</p> -</blockquote> -<p>But the following would both fail:</p> -<blockquote> - <p class="code">child.expect ('\w+\n')</p> -</blockquote> -<p>And as explained before, trying to use '$' to match the end of line -would not work either:</p> -<blockquote> - <p class="code">child.expect ('\w+$')</p> -</blockquote> -<p>So if you need to explicitly look for the END OF LINE, you want to -look for the CR/LF combination -- not just the LF and not the $ pattern.</p> -<p>This problem is not limited to Pexpect. This problem happens any -time you try to perform a regular expression match on a stream. Regular -expressions need to look ahead. With a stream it is hard to look ahead -because the process generating the stream may not be finished. There is no -way to know if the process has paused momentarily or is finished and -waiting for you. <font color="#cc0000">Pexpect must implicitly always -do a NON greedy match (minimal) at the end of a input {### already said -this}.</font> </p> -<p>Pexpect compiles all regular expressions with the DOTALL flag.

Expect that -character to delimit the string. For example, you might try making the -end of your pattrn be <span class="code">\D+</span> instead of <span - class="code">\D*</span>. That means number digits alone would not -satisfy the (<span class="code">\d+</span>) pattern. You would need -some number(s) and at least one <span class="code">\D</span> at the -end. </p> -<h2>Matching groups</h2> -<p>You can group regular expression using parenthesis.

For debugging it's very useful to -use the following pattern:</p> -<p>try:<br> - i = child.expect ([pattern1, pattern2, pattern3, -etc])<br> -except:<br> - print "Exception was thrown"<br> - print "debug information:"<br> - print str(child)<br> -</p> -<p>It is also useful to log the child's input and out to a file or the -screen.

That's done by a shell not the -command you are spawning. This is a common mistake. If you want to run a -command and pipe it through another command then you must also start a shell. -For example: - -<pre> - child = pexpect.spawn('/bin/sh -c "ls -l | grep LOG > log_list.txt"') - child.expect(pexpect.EOF) -</pre> - -The second form of spawn (where you pass a list of arguments) is useful in -situations where you wish to spawn a command and pass it its own argument list. -This can make syntax more clear. For example, the following is equivalent to -the previous example: - -<pre> - shell_cmd = 'ls -l | grep LOG > log_list.txt' - child = pexpect.spawn ('/bin/sh', ['-c', shell_cmd]) - child.expect (pexpect.EOF) -</pre> - -</p> -<p><b>Q: Isn't there already a Python Expect?</b></p> -<p>A: Yes, there are several of them. They usually require you to -compile C. I wanted something that was pure Python and preferably a -single module that was simple to install. I also wanted something that -was easy to use. This pure Python expect only recently became possible -with the introduction of the pty module in the standard Python library. -Previously C extensions were required.</p> - -<p><strong>Q: The before and after properties sound weird.</strong></p> -<p>Originally I was going to model Pexpect more after Expect, but then -I found that I could never remember how to get the context of the stuff -I was trying to parse. I hate having to read my own documentation. I -decided that it was easier for me to remember what before and after -was. It just so happens that this is how the -B and -A options in grep -works, so that made it even easier for me to remember. Whatever makes -my life easier is what's best.</p> - -<p><b>Q: Why not just use Expect?</b></p> -<p>A: I love it. It's great. I has bailed me out of some real jams, but -I wanted something that would do 90% of what I need from Expect; be 10% -of the size; and allow me to write my code in Python instead of TCL. -Pexpect is not nearly as big as Expect, but Pexpect does everything I -have ever used Expect for. -<!-- :-P If I liked TCL then you wouldn't be reading this. My appologies to Don Libes -- Expect is cool, TK is cool, but TCL is only slightly better than Perl in my book. Hopefully after Expyct is done I will not need to use Expect anymore -- except for that lovely autoexpect tool. Damn, I wish I had that! --> </p> - -<p><b>Q: Why not just use a pipe (popen())?</b></p> -<p>A: A pipe works fine for getting the output to non-interactive -programs. If you just want to get the output from <span class="code">ls</span>, -<span class="code">uname</span>, or <span class="code">ping</span> -then this works. Pipes do not work very well for interactive programs -and pipes will almost certainly fail for most applications that ask for -passwords such as telnet, ftp, or ssh.</p> -<p>There are two reasons for this. </p> -<p>First an application may bypass stdout and print directly to its -controlling TTY. Something like SSH will do this when it asks you for a -password. This is why you cannot redirect the password prompt because -it does not go through stdout or stderr.</p> -<p>The second reason is because most applications are built using the C -Standard IO Library (anything that uses <span class="code">#include -<stdio.h></span>). One of the features of the stdio library is -that it buffers all input and output. Normally output is <b><i>line -buffered</i></b> when a program is printing to a TTY (your terminal -screen). Every time the program prints a line-feed the currently -buffered data will get printed to your screen. The problem comes when -you connect a pipe. The stdio library is smart and can tell that it is -printing to a pipe instead of a TTY. In that case it switches from line -buffer mode to <i><b>block buffered</b></i>. In this mode the -currently buffered data is flushed when the buffer is full. This causes -most interactive programs to deadlock. Block buffering is more -efficient when writing to disks and pipes. Take the situation where a -program prints a message "Enter your user name:\n" and then waits for -you type type something. In block buffered mode, the stdio library will -not put the message into the pipe even though a linefeed is printed. -The result is that you never receive the message, yet the child -application will sit and wait for you to type a response. Don't confuse -the stdio lib's buffer with the pipe's buffer. The pipe buffer is -another area that can cause problems. You could flush the input side of -a pipe, whereas you have no control over the stdio library buffer. </p> -<p>More information: the Standard IO library has three states for a -FILE *. These are: _IOFBF for block buffered; _IOLBF for line buffered; -and _IONBF for unbuffered. The STDIO lib will use block buffering when -talking to a block file descriptor such as a pipe. This is usually not -helpful for interactive programs. Short of recompiling your program to -include fflush() everywhere or recompiling a custom stdio library there -is not much a controlling application can do about this if talking over -a pipe.</p> -<p> The program may have put data in its output that remains unflushed -because the output buffer is not full; then the program will go and -deadlock while waiting for input -- because you never send it any -because you are still waiting for its output (still stuck in the -STDIO's output buffer).</p> -<p>The answer is to use a pseudo-tty. A TTY device will force <i><b>line</b></i> -buffering (as opposed to block buffering). Line buffering means that -you will get each line when the child program sends a line feed. This -corresponds to the way most interactive programs operate -- send a line -of output then wait for a line of input.</p> -<p>I put "answer" in quotes because it's ugly solution and because -there is no POSIX standard for pseudo-TTY devices (even though they -have a TTY standard...). What would make more sense to me would be to -have some way to set a mode on a file descriptor so that it will tell -the STDIO to be line-buffered. I have investigated, and I don't think -there is a way to set the buffered state of a child process. The STDIO -Library does not maintain any external state in the kernel or whatnot, -so I don't think there is any way for you to alter it. I'm not quite -sure how this line-buffered/block-buffered state change happens -internally in the STDIO library. I think the STDIO lib looks at the -file descriptor and decides to change behavior based on whether it's a -TTY or a block file (see isatty()).</p> -<p>I hope that this qualifies as helpful.</p> - -<h1>Don't use a pipe to control another application...</h1> -<p>Pexpect may seem similar to <span class="code">os.popen()</span> or -<span class="code">commands</span> module. The main difference is that -Pexpect (like Expect) uses a pseudo-TTY to talk to the child -application. Most applications do no work well through the system() -call or through pipes. And probably all applications that ask a user to -type in a password will fail. These applications bypass the stdin and -read directly from the TTY device. Many applications do not explicitly -flush their output buffers. This causes deadlocks if you try to control -an interactive application using a pipe. What happens is that most UNIX -applications use the stdio (#include <stdio.h>) for input and -output. The stdio library behaves differently depending on where the -output is going. There is no way to control this behavior from the -client end.<br> -</p> - -<p><b>Q: Can I do screen scraping with this thing?</b></p> -<p>A: That depends. If your application just does line-oriented output -then this is easy. If it does screen-oriented output then it may work, -but it could be hard. For example, trying to scrape data from the 'top' -command would be hard. The top command repaints the text window. </p> -<p>I am working on an ANSI / VT100 terminal emulator that will have -methods to get characters from an arbitrary X,Y coordinate of the -virtual screen. It works and you can play with it, but I have no -working examples at this time.</p> -<hr noshade="noshade" size="1"> -<h1><a name="bugs"></a>Bugs</h1> -<h2>Threads</h2> -<p>On Linux (RH 8) you cannot spawn a child from a different thread and -pass the handle back to a worker thread.

You may read back what you just wrote even if the -child application does not explicitly echo it. Timing is critical. This -could be a security issue when talking to an application that asks for -a password; otherwise, this does not seem like a big deal. <i>But why -do TTYs do this</i>?</p> -<p>People usually report this when they are trying to control SSH or -some other login. For example, if your code looks something like this: </p> -<pre class="code">child.expect ('[pP]assword:')<br>child.sendline (my_password)</pre> -<p><br> -<blockquote> -1. SSH prints "password:" prompt to the user.<br> -2. SSH turns off echo on the TTY device.<br> -3. SSH waits for user to enter a password.<br> -</blockquote> -When scripting with Pexpect what can happen is that Pexpect will response to the "password:" prompt -before SSH has had time to turn off TTY echo. In other words, Pexpect sends the password between -steps 1. and 2., so the password gets echoed back to the TTY. I would call this an SSH bug. -</p> -<p> -Pexpect now automatically adds a short delay before sending data to a child process. -This more closely mimics what happens in the usual human-to-app interaction. -The delay can be tuned with the 'delaybeforesend' attribute of the spawn class. -In general, this fixes the problem for everyone and so this should not be an issue -for most users.

This -means that your Pexpect application will receive an EOF even though it -should have received a little more data before the child died. This is -not generally a problem when talking to interactive child applications. -One example where it is a problem is when trying to read output from a -program like '<span class="code">ls</span>'. You may receive most of -the directory listing, but the last few lines will get lost before you -receive an EOF. The reason for this is that '<span class="code">ls</span>' -runs; completes its task; and then exits. The buffer is not flushed -before exit so the last few lines are lost. The following example -demonstrates the problem:</p> -<p> </p> -<blockquote> - <pre class="code">child = pexpect.spawn ('ls -l')<br>child.expect (pexpect.EOF)<br>print child.before <br> </pre> -</blockquote> -<p></p> - -<h2>Controlling SSH on Solaris</h2> -<p>Pexpect does not yet work perfectly on Solaris. -One common problem is that SSH sometimes will not allow TTY password -authentication. For example, you may expect SSH to ask you for a -password using code like this: -</p> -<pre class="code">child = pexpect.spawn ('ssh user@example.com')<br>child.expect ('assword')<br>child.sendline ('mypassword')<br></pre> -You may see the following error come back from a spawned -child SSH: -<p></p> -<blockquote>Permission denied (publickey,keyboard-interactive). </blockquote> -<p> -This means that SSH thinks it can't access the TTY to ask you for your -password. -The only solution I have found is to use public key authentication with -SSH. -This bypasses the need for a password. I'm not happy with this -solution. -The problem is due to poor support for Solaris Pseudo TTYs in the -Python -Standard Library. </p> -<hr noshade="noshade" size="1"> -<h1><a name="changes"></a>CHANGES</h1> -<h2>Current Release</h2> -<p>Fixed OSError exception when a pexpect object is cleaned up. -Previously you might have seen this exception:</p> -<blockquote> - <pre class="code">Exception exceptions.OSError: (10, 'No child processes') <br>in <bound method spawn.__del__ of<br><pexpect.spawn instance at 0xd248c>> ignored</pre> -</blockquote> -<p>You should not see that anymore. Thanks to Michael Surette.</p> -<p>Added support for buffering reads. This greatly improves speed when -trying to match long output from a child process. When you create an -instance of the spawn object you can then set a buffer size. For now -you MUST do the following to turn on buffering -- it may be on by -default in future version.</p> -<blockquote> - <pre class="code">child = pexpect.spawn ('my_command')<br>child.maxread=1000 # Sets buffer to 1000 characters.</pre> -</blockquote> -<div> -<p>I made a subtle change to the way TIMEOUT and EOF exceptions behave. -Previously you could either expect these states in which case pexpect -will not raise an exception, or you could just let pexpect raise an -exception when these states were encountered. If you expected the -states then the 'before' property was set to everything before the -state was encountered, but if you let pexpect raise the exception then -'before' was not set. Now the 'before' property will get set either way -you choose to handle these states.</p> -<h2><i>Older changes...</i></h2> -<p>The spawn object now provides iterators for a <i>file-like interface</i>. -This makes Pexpect a more complete file-like object. You can now write -code like this:</p> -<blockquote> - <pre class="code">child = pexpect.spawn ('ls -l')<br>for line in child:<br> print line<br></pre> -</blockquote> -<p>I added the attribute <span class="code">exitstatus</span>. This -will give the exit code returned by the child process. This will be set -to <span class="code">None</span> while the child is still alive. When -<span class="code">isalive()</span> returns 0 then <span class="code">exitstatus</span> -will be set.</p> -<p>I made a few more tweaks to <span class="code">isalive()</span> so -that it will operate more consistently on different platforms. Solaris -is the most difficult to support.</p> -<p> </p> -<p>You can now put <span class="code">TIMEOUT</span> in a list of -expected patterns. This is just like putting <span class="code">EOF</span> -in the pattern list. Expecting for a <span class="code">TIMEOUT</span> -may not be used as often as <span class="code">EOF</span>, but this -makes Pexpect more consitent.</p> -<p>Thanks to a suggestion and sample code from Chad J. Schroeder I -added the ability for Pexpect to operate on a file descriptor that is -already open. This means that Pexpect can be used to control streams -such as those from serial port devices. Now you just pass the integer -file descriptor as the "command" when contsructing a spawn open. For -example on a Linux box with a modem on ttyS1:</p> -<blockquote> - <pre class="code">fd = os.open("/dev/ttyS1", os.O_RDWR|os.O_NONBLOCK|os.O_NOCTTY)<br>m = pexpect.spawn(fd) # Note integer fd is used instead of usual string.<br>m.send("+++") # Escape sequence<br>m.send("ATZ0\r") # Reset modem to profile 0<br>rval = m.expect(["OK", "ERROR"])</pre> -</blockquote> -<h3>Pexpect now tests itself on Compile Farm!</h3> -<p>I wrote a nice script that uses ssh to connect to each machine on -Source Forge's Compile Farm and then run the testall.py script for each -platform. The result of the test is then recorded for each platform. -Now it's easy to run regression tests across multiple platforms.</p> -<h3>Pexpect is a file-like object</h3> -<p>The spawn object now provides a <i>file-like interface</i>. It -supports most of the methods and attributes defined for Python File -Objects. </p> -<p>I changed write and writelines() so that they no longer return a -value. Use send() if you need that functionality. I did this to make -the Spawn object more closely match a file-like object.</p> -<p>read() was renamed to read_nonblocking(). I added a new read() -method that matches file-like object interface. In general, you should -not notice the difference except that read() no longer allows you to -directly set the timeout value. I hope this will not effect any -existing code. Switching to read_nonblocking() should fix existing code.</p> -<p>I changed the name of <span class="code">set_echo()</span> to <span - class="code">setecho()</span>.</p> -<p>I changed the name of <span class="code">send_eof()</span> to <span - class="code">sendeof()</span>.</p> -<p>I modified <span class="code">kill()</span> so that it checks to -make sure the pid isalive().</p> -<p>I modified <span class="code">spawn()</span> (really called from <span - class="code">__spawn()</span>)so that it does not raise an expection -if <span class="code">setwinsize()</span> fails. Some platforms such -as Cygwin do not like setwinsize. This was a constant problem and since -it is not a critical feature I decided to just silence the error. -Normally I don't like to do that, but in this case I'm making an -exception.</p> -<p>Added a method <span class="code">close()</span> that does what you -think. It closes the file descriptor of the child application. It makes -no attempt to actually kill the child or wait for its status. </p> -<p>Add variables <span class="code">__version__</span> and <span - class="code">__revision__</span> (from cvs) to the pexpect modules. -This is mainly helpful to me so that I can make sure that I'm testing -with the right version instead of one already installed.</p> -<h3>Logging changes</h3> -<blockquote> - <p><span class="code">log_open()</span> and <span class="code">log_close()</span> -have been removed. Now use <span class="code">setlog()</span>. The <span - class="code">setlog()</span> method takes a file object. This is far -more flexible than the previous log method. Each time data is written -to the file object it will be flushed. To turn logging off simply call <span - class="code">setlog()</span> with None.</p> -</blockquote> -<h2>isalive changes</h2> -<blockquote> - <p>I renamed the <span class="code">isAlive()</span> method to <span - class="code">isalive()</span> to match the more typical naming style -in Python. Also the technique used to detect child process status has -been drastically modified. Previously I did some funky stuff with -signals which caused indigestion in other Python modules on some -platforms. It's was a big headache. It still is, but I think it works -better now.</p> -</blockquote> -<h3>attribute name changes</h3> -<blockquote> - <p>The names of some attributes have been changed.

This is especially -handy if you are writing automated test tools.</p> - -<p>There are two important methods in Pexpect -- <span class="code"><b>expect()</b></span> -and <span class="code"><b>send()</b></span> (or <span class="code">sendline()</span> -which is like <span class="code">send()</span> with a linefeed). -The <span class="code">expect()</span> method waits for the child application -to return a given string.

From the child's point of -view it looks just like someone typed the text from a terminal. After -each call to <span class="code"><b>expect()</b></span> the <span - class="code"><b>before</b></span> and <span class="code"><b>after</b></span> -properties will be set to the text printed by child application.

Yes, that does appear to be DOS-style. -It may surprise some UNIX people to learn that terminal TTY device drivers -(dumb, vt100, ANSI, xterm, etc.) all use the CR/LF combination to signify -the end of line. Pexpect uses a Pseudo-TTY device to talk to the child application, so -when the child app prints "\n" you actually see "\r\n". -</p> -<p><b>UNIX uses just linefeeds to end lines of text, but not when it -comes to TTY devices!</b> TTY devices are more like the Windows world. -Each line of text end with a CR/LF combination. When you intercept data -from a UNIX command from a TTY device you will find that the TTY device -outputs a CR/LF combination. A UNIX command may only write a linefeed -(\n), but the TTY device driver converts it to CR/LF. This means that -your terminal will see lines end with CR/LF (hex <span class="code">0D 0A</span>). -Since Pexpect emulates a terminal, to match ends of lines you have to -expect the CR/LF combination.</p> -<blockquote> - <p class="code">child.expect ('\r\n')</p> -</blockquote> -<p>If you just need to skip past a new line then <span class="code">expect -('\n')</span> by itself will work, but if you are expecting a specific -pattern before the end of line then you need to explicitly look for the -\r. For example the following expects a word at the end of a line:</p> -<blockquote> - <p class="code">child.expect ('\w+\r\n')</p> -</blockquote> -<p>But the following would both fail:</p> -<blockquote> - <p class="code">child.expect ('\w+\n')</p> -</blockquote> -<p>And as explained before, trying to use '$' to match the end of line -would not work either:</p> -<blockquote> - <p class="code">child.expect ('\w+$')</p> -</blockquote> -<p>So if you need to explicitly look for the END OF LINE, you want to -look for the CR/LF combination -- not just the LF and not the $ pattern.</p> -<p>This problem is not limited to Pexpect. This problem happens any -time you try to perform a regular expression match on a stream. Regular -expressions need to look ahead. With a stream it is hard to look ahead -because the process generating the stream may not be finished.

That's done by a shell not the -command you are spawning. This is a common mistake. If you want to run a -command and pipe it through another command then you must also start a shell. -For example: - -<pre> - child = pexpect.spawn('/bin/sh -c "ls -l | grep LOG > log_list.txt"') - child.expect(pexpect.EOF) -</pre> - -The second form of spawn (where you pass a list of arguments) is useful in -situations where you wish to spawn a command and pass it its own argument list. -This can make syntax more clear. For example, the following is equivalent to -the previous example: - -<pre> - shell_cmd = 'ls -l | grep LOG > log_list.txt' - child = pexpect.spawn ('/bin/sh', ['-c', shell_cmd]) - child.expect (pexpect.EOF) -</pre> - -</p> -<p><b>Q: Isn't there already a Python Expect?</b></p> -<p>A: Yes, there are several of them. They usually require you to -compile C. I wanted something that was pure Python and preferably a -single module that was simple to install. I also wanted something that -was easy to use. This pure Python expect only recently became possible -with the introduction of the pty module in the standard Python library. -Previously C extensions were required.</p> - -<p><strong>Q: The before and after properties sound weird.</strong></p> -<p>Originally I was going to model Pexpect more after Expect, but then -I found that I could never remember how to get the context of the stuff -I was trying to parse. I hate having to read my own documentation. I -decided that it was easier for me to remember what before and after -was. It just so happens that this is how the -B and -A options in grep -works, so that made it even easier for me to remember. Whatever makes -my life easier is what's best.</p> - -<p><b>Q: Why not just use Expect?</b></p> -<p>A: I love it. It's great. I has bailed me out of some real jams, but -I wanted something that would do 90% of what I need from Expect; be 10% -of the size; and allow me to write my code in Python instead of TCL. -Pexpect is not nearly as big as Expect, but Pexpect does everything I -have ever used Expect for. -<!-- :-P If I liked TCL then you wouldn't be reading this. My appologies to Don Libes -- Expect is cool, TK is cool, but TCL is only slightly better than Perl in my book. Hopefully after Expyct is done I will not need to use Expect anymore -- except for that lovely autoexpect tool. Damn, I wish I had that! --> </p> - -<p><b>Q: Why not just use a pipe (popen())?</b></p> -<p>A: A pipe works fine for getting the output to non-interactive -programs. If you just want to get the output from <span class="code">ls</span>, -<span class="code">uname</span>, or <span class="code">ping</span> -then this works. Pipes do not work very well for interactive programs -and pipes will almost certainly fail for most applications that ask for -passwords such as telnet, ftp, or ssh.</p> -<p>There are two reasons for this. </p> -<p>First an application may bypass stdout and print directly to its -controlling TTY. Something like SSH will do this when it asks you for a -password. This is why you cannot redirect the password prompt because -it does not go through stdout or stderr.</p> -<p>The second reason is because most applications are built using the C -Standard IO Library (anything that uses <span class="code">#include -<stdio.h></span>). One of the features of the stdio library is -that it buffers all input and output. Normally output is <b><i>line -buffered</i></b> when a program is printing to a TTY (your terminal -screen). Every time the program prints a line-feed the currently -buffered data will get printed to your screen. The problem comes when -you connect a pipe. The stdio library is smart and can tell that it is -printing to a pipe instead of a TTY. In that case it switches from line -buffer mode to <i><b>block buffered</b></i>. In this mode the -currently buffered data is flushed when the buffer is full. This causes -most interactive programs to deadlock. Block buffering is more -efficient when writing to disks and pipes. Take the situation where a -program prints a message "Enter your user name:\n" and then waits for -you type type something. In block buffered mode, the stdio library will -not put the message into the pipe even though a linefeed is printed. -The result is that you never receive the message, yet the child -application will sit and wait for you to type a response. Don't confuse -the stdio lib's buffer with the pipe's buffer. The pipe buffer is -another area that can cause problems. You could flush the input side of -a pipe, whereas you have no control over the stdio library buffer. </p> -<p>More information: the Standard IO library has three states for a -FILE *. These are: _IOFBF for block buffered; _IOLBF for line buffered; -and _IONBF for unbuffered. The STDIO lib will use block buffering when -talking to a block file descriptor such as a pipe. This is usually not -helpful for interactive programs. Short of recompiling your program to -include fflush() everywhere or recompiling a custom stdio library there -is not much a controlling application can do about this if talking over -a pipe.</p> -<p> The program may have put data in its output that remains unflushed -because the output buffer is not full; then the program will go and -deadlock while waiting for input -- because you never send it any -because you are still waiting for its output (still stuck in the -STDIO's output buffer).</p> -<p>The answer is to use a pseudo-tty. A TTY device will force <i><b>line</b></i> -buffering (as opposed to block buffering). Line buffering means that -you will get each line when the child program sends a line feed. This -corresponds to the way most interactive programs operate -- send a line -of output then wait for a line of input.</p> -<p>I put "answer" in quotes because it's ugly solution and because -there is no POSIX standard for pseudo-TTY devices (even though they -have a TTY standard...). What would make more sense to me would be to -have some way to set a mode on a file descriptor so that it will tell -the STDIO to be line-buffered. I have investigated, and I don't think -there is a way to set the buffered state of a child process. The STDIO -Library does not maintain any external state in the kernel or whatnot, -so I don't think there is any way for you to alter it. I'm not quite -sure how this line-buffered/block-buffered state change happens -internally in the STDIO library. I think the STDIO lib looks at the -file descriptor and decides to change behavior based on whether it's a -TTY or a block file (see isatty()).</p> -<p>I hope that this qualifies as helpful.</p> - -<h1>Don't use a pipe to control another application...</h1> -<p>Pexpect may seem similar to <span class="code">os.popen()</span> or -<span class="code">commands</span> module. The main difference is that -Pexpect (like Expect) uses a pseudo-TTY to talk to the child -application. Most applications do no work well through the system() -call or through pipes. And probably all applications that ask a user to -type in a password will fail. These applications bypass the stdin and -read directly from the TTY device. Many applications do not explicitly -flush their output buffers. This causes deadlocks if you try to control -an interactive application using a pipe. What happens is that most UNIX -applications use the stdio (#include <stdio.h>) for input and -output. The stdio library behaves differently depending on where the -output is going. There is no way to control this behavior from the -client end.<br> -</p> - -<p><b>Q: Can I do screen scraping with this thing?</b></p> -<p>A: That depends. If your application just does line-oriented output -then this is easy. If it does screen-oriented output then it may work, -but it could be hard. For example, trying to scrape data from the 'top' -command would be hard. The top command repaints the text window. </p> -<p>I am working on an ANSI / VT100 terminal emulator that will have -methods to get characters from an arbitrary X,Y coordinate of the -virtual screen.

For example, if your code looks something like this: </p> -<pre class="code">child.expect ('[pP]assword:')<br>child.sendline (my_password)</pre> -<p><br> -<blockquote> -1. SSH prints "password:" prompt to the user.<br> -2. SSH turns off echo on the TTY device.<br> -3. SSH waits for user to enter a password.<br> -</blockquote> -When scripting with Pexpect what can happen is that Pexpect will response to the "password:" prompt -before SSH has had time to turn off TTY echo. In other words, Pexpect sends the password between -steps 1. and 2., so the password gets echoed back to the TTY. I would call this an SSH bug. -</p> -<p> -Pexpect now automatically adds a short delay before sending data to a child process. -This more closely mimics what happens in the usual human-to-app interaction. -The delay can be tuned with the 'delaybeforesend' attribute of the spawn class. -In general, this fixes the problem for everyone and so this should not be an issue -for most users.

This is -not generally a problem when talking to interactive child applications. -One example where it is a problem is when trying to read output from a -program like '<span class="code">ls</span>'. You may receive most of -the directory listing, but the last few lines will get lost before you -receive an EOF. The reason for this is that '<span class="code">ls</span>' -runs; completes its task; and then exits. The buffer is not flushed -before exit so the last few lines are lost. The following example -demonstrates the problem:</p> -<p> </p> -<blockquote> - <pre class="code">child = pexpect.spawn ('ls -l')<br>child.expect (pexpect.EOF)<br>print child.before <br> </pre> -</blockquote> -<p></p> - -<h2>Controlling SSH on Solaris</h2> -<p>Pexpect does not yet work perfectly on Solaris. -One common problem is that SSH sometimes will not allow TTY password -authentication.

For example:: - - child = pexpect.spawn('/bin/bash -c "ls -l | grep LOG > log_list.txt"') - child.expect(pexpect.EOF) - - The second form of spawn (where you pass a list of arguments) is useful - in situations where you wish to spawn a command and pass it its own - argument list.

This is maximum number - of bytes that Pexpect will try to read from a TTY at one time. Setting - the maxread size to 1 will turn off buffering. Setting the maxread - value higher may help performance in cases where large amounts of - output are read back from the child. This feature is useful in - conjunction with searchwindowsize. - - The searchwindowsize attribute sets the how far back in the incomming - seach buffer Pexpect will search for pattern matches. Every time - Pexpect reads some data from the child it will append the data to the - incomming buffer. The default is to search from the beginning of the - imcomming buffer each time new data is read from the child. But this is - very inefficient if you are running a command that generates a large - amount of data where you want to match The searchwindowsize does not - effect the size of the incomming data buffer.

Set logfile to None to stop - logging. This is the default. Set logfile to sys.stdout to echo - everything to standard output. The logfile is flushed after each write. - - Example log input and output to a file:: - - child = pexpect.spawn('some_command') - fout = file('mylog.txt','w') - child.logfile = fout - - Example log to stdout:: - - child = pexpect.spawn('some_command') - child.logfile = sys.stdout - - The logfile_read and logfile_send members can be used to separately log - the input from the child and output sent to the child. Sometimes you - don't want to see everything you write to the child. You only want to - log what the child sends back. For example:: - - child = pexpect.spawn('some_command') - child.logfile_read = sys.stdout - - To separately log output sent to the child use logfile_send:: - - self.logfile_send = fout - - The delaybeforesend helps overcome a weird behavior that many users - were experiencing. The typical problem was that a user would expect() a - "Password:" prompt and then immediately call sendline() to send the - password. The user would then see that their password was echoed back - to them. Passwords don't normally echo. The problem is caused by the - fact that most applications print out the "Password" prompt and then - turn off stdin echo, but if you send your password before the - application turned off echo, then you get your password echoed. - Normally this wouldn't be a problem when interacting with a human at a - real keyboard. If you introduce a slight delay just before writing then - this seems to clear up the problem. This was such a common problem for - many users that I decided that the default pexpect behavior should be - to sleep just before writing to the child application. 1/20th of a - second (50 ms) seems to be enough to clear up the problem. You can set - delaybeforesend to 0 to return to the old behavior. Most Linux machines - don't like this to be below 0.03. I don't know why. - - Note that spawn is clever about finding commands on your path. - It uses the same logic that "which" uses to find executables. - - If you wish to get the exit status of the child you must call the - close() method.

If the child exited normally - then exitstatus will store the exit return code and signalstatus will - be None. If the child was terminated abnormally with a signal then - signalstatus will store the signal value and exitstatus will be None. - If you need more detail you can also read the self.status member which - stores the status returned by os.waitpid.

Is there a mailing list?** + +A: You can use the `pexpect tag on Stackoverflow <http://stackoverflow.com/questions/tagged/pexpect>`__ +to ask questions specifically related to Pexpect. For more general Python +support, there's the python-list_ mailing list, and the `#python`_ +IRC channel. Please refrain from using github for general +python or systems scripting support. + +.. _python-list: https://mail.python.org/mailman/listinfo/python-list +.. _#python: https://www.python.org/community/irc/ + +**Q: Why don't shell pipe and redirect (| and >) work when I spawn a command?** + +A: Remember that Pexpect does NOT interpret shell meta characters such as +redirect, pipe, or wild cards (``>``, ``|``, or ``*``). That's done by a shell not +the command you are spawning. This is a common mistake. If you want to run a +command and pipe it through another command then you must also start a shell. +For example:: + + child = pexpect.spawn('/bin/bash -c "ls -l | grep LOG > log_list.txt"') + child.expect(pexpect.EOF) + +The second form of spawn (where you pass a list of arguments) is useful in +situations where you wish to spawn a command and pass it its own argument list. +This can make syntax more clear. For example, the following is equivalent to the +previous example:: + + shell_cmd = 'ls -l | grep LOG > log_list.txt' + child = pexpect.spawn('/bin/bash', ['-c', shell_cmd]) + child.expect(pexpect.EOF) + +**Q: The `before` and `after` properties sound weird.** + +A: This is how the -B and -A options in grep works, so that made it +easier for me to remember. Whatever makes my life easier is what's best. +Originally I was going to model Pexpect after Expect, but then I found +that I didn't actually like the way Expect did some things. It was more +confusing. The `after` property can be a little confusing at first, +because it will actually include the matched string. The `after` means +after the point of match, not after the matched string. + +**Q: Why not just use Expect?** + +A: I love it. It's great. I has bailed me out of some real jams, but I +wanted something that would do 90% of what I need from Expect; be 10% of +the size; and allow me to write my code in Python instead of TCL. +Pexpect is not nearly as big as Expect, but Pexpect does everything I +have ever used Expect for. + +.. _whynotpipe: + +**Q: Why not just use a pipe (popen())?** + +A: A pipe works fine for getting the output to non-interactive programs. +If you just want to get the output from ls, uname, or ping then this +works. Pipes do not work very well for interactive programs and pipes +will almost certainly fail for most applications that ask for passwords +such as telnet, ftp, or ssh. + +There are two reasons for this. + +* First an application may bypass stdout and print directly to its + controlling TTY. Something like SSH will do this when it asks you for + a password. This is why you cannot redirect the password prompt because + it does not go through stdout or stderr. + +* The second reason is because most applications are built using the C + Standard IO Library (anything that uses ``#include <stdio.h>``). One + of the features of the stdio library is that it buffers all input and + output. Normally output is line buffered when a program is printing to + a TTY (your terminal screen). Everytime the program prints a line-feed + the currently buffered data will get printed to your screen. The + problem comes when you connect a pipe. The stdio library is smart and + can tell that it is printing to a pipe instead of a TTY. In that case + it switches from line buffer mode to block buffered. In this mode the + currently buffered data is flushed when the buffer is full. This + causes most interactive programs to deadlock. Block buffering is more + efficient when writing to disks and pipes. Take the situation where a + program prints a message ``"Enter your user name:\n"`` and then waits + for you type type something. In block buffered mode, the stdio library + will not put the message into the pipe even though a linefeed is + printed. The result is that you never receive the message, yet the + child application will sit and wait for you to type a response. Don't + confuse the stdio lib's buffer with the pipe's buffer. The pipe buffer + is another area that can cause problems. You could flush the input + side of a pipe, whereas you have no control over the stdio library buffer. + +More information: the Standard IO library has three states for a +``FILE *``. These are: _IOFBF for block buffered; _IOLBF for line buffered; +and _IONBF for unbuffered. The STDIO lib will use block buffering when +talking to a block file descriptor such as a pipe. This is usually not +helpful for interactive programs. Short of recompiling your program to +include fflush() everywhere or recompiling a custom stdio library there +is not much a controlling application can do about this if talking over +a pipe. + +The program may have put data in its output that remains unflushed +because the output buffer is not full; then the program will go and +deadlock while waiting for input -- because you never send it any +because you are still waiting for its output (still stuck in the STDIO's +output buffer). + +The answer is to use a pseudo-tty. A TTY device will force line +buffering (as opposed to block buffering). Line buffering means that you +will get each line when the child program sends a line feed. This +corresponds to the way most interactive programs operate -- send a line +of output then wait for a line of input. + +I put "answer" in quotes because it's ugly solution and because there is +no POSIX standard for pseudo-TTY devices (even though they have a TTY +standard...). What would make more sense to me would be to have some way +to set a mode on a file descriptor so that it will tell the STDIO to be +line-buffered. I have investigated, and I don't think there is a way to +set the buffered state of a child process. The STDIO Library does not +maintain any external state in the kernel or whatnot, so I don't think +there is any way for you to alter it. I'm not quite sure how this +line-buffered/block-buffered state change happens internally in the +STDIO library. I think the STDIO lib looks at the file descriptor and +decides to change behavior based on whether it's a TTY or a block file +(see isatty()). + +I hope that this qualifies as helpful. Don't use a pipe to control +another application. + +**Q: Can I do screen scraping with this thing?** + +A: That depends. If your application just does line-oriented output then +this is easy. If a program emits many terminal sequences, from video +attributes to screen addressing, such as programs using curses, then +it may become very difficult to ascertain what text is displayed on a screen. + +We suggest using the `pyte <https://github.com/selectel/pyte>`_ library to +screen-scrape. The module :mod:`pexpect.ANSI` released with previous versions +of pexpect is now marked deprecated and may be removed in the future. + +**Q: I get strange behavior with pexect and gevent** + +A: Pexpect uses fork(2), exec(2), select(2), waitpid(2), and implements its +own selector in expect family of calls. pexpect has been known to misbehave +when paired with gevent. A solution might be to isolate your pexpect +dependent code from any frameworks that manipulate event selection behavior +by running it in an another process entirely. diff --git a/lldb/third_party/Python/module/pexpect-4.6/doc/Makefile b/lldb/third_party/Python/module/pexpect-4.6/doc/Makefile new file mode 100644 index 000000000000..ced8a6852639 --- /dev/null +++ b/lldb/third_party/Python/module/pexpect-4.6/doc/Makefile @@ -0,0 +1,153 @@ +# Makefile for Sphinx documentation +# + +# You can set these variables from the command line. +SPHINXOPTS = +SPHINXBUILD = sphinx-build +PAPER = +BUILDDIR = _build + +# Internal variables. +PAPEROPT_a4 = -D latex_paper_size=a4 +PAPEROPT_letter = -D latex_paper_size=letter +ALLSPHINXOPTS = -d $(BUILDDIR)/doctrees $(PAPEROPT_$(PAPER)) $(SPHINXOPTS) . +# the i18n builder cannot share the environment and doctrees with the others +I18NSPHINXOPTS = $(PAPEROPT_$(PAPER)) $(SPHINXOPTS) . + +.PHONY: help clean html dirhtml singlehtml pickle json htmlhelp qthelp devhelp epub latex latexpdf text man changes linkcheck doctest gettext + +help: + @echo "Please use \`make <target>' where <target> is one of" + @echo " html to make standalone HTML files" + @echo " dirhtml to make HTML files named index.html in directories" + @echo " singlehtml to make a single large HTML file" + @echo " pickle to make pickle files" + @echo " json to make JSON files" + @echo " htmlhelp to make HTML files and a HTML help project" + @echo " qthelp to make HTML files and a qthelp project" + @echo " devhelp to make HTML files and a Devhelp project" + @echo " epub to make an epub" + @echo " latex to make LaTeX files, you can set PAPER=a4 or PAPER=letter" + @echo " latexpdf to make LaTeX files and run them through pdflatex" + @echo " text to make text files" + @echo " man to make manual pages" + @echo " texinfo to make Texinfo files" + @echo " info to make Texinfo files and run them through makeinfo" + @echo " gettext to make PO message catalogs" + @echo " changes to make an overview of all changed/added/deprecated items" + @echo " linkcheck to check all external links for integrity" + @echo " doctest to run all doctests embedded in the documentation (if enabled)" + +clean: + -rm -rf $(BUILDDIR)/* + +html: + $(SPHINXBUILD) -b html $(ALLSPHINXOPTS) $(BUILDDIR)/html + @echo + @echo "Build finished.

[Adam Kerrison] + +Timing issue with send() and sendline() +--------------------------------------- + +This problem has been addressed and should not affect most users. + +It is sometimes possible to read an echo of the string sent with +:meth:`~pexpect.spawn.send` and :meth:`~pexpect.spawn.sendline`. If you call +:meth:`~pexpect.spawn.send` and then immediately call :meth:`~pexpect.spawn.readline`, +you may get part of your output echoed back. You may read back what you just +wrote even if the child application does not explicitly echo it. Timing is +critical. This could be a security issue when talking to an application that +asks for a password; otherwise, this does not seem like a big deal. But why do +TTYs do this? + +People usually report this when they are trying to control SSH or some other +login. For example, if your code looks something like this:: + + child.expect ('[pP]assword:') + child.sendline (my_password) + + +1. SSH prints "password:" prompt to the user. +2. SSH turns off echo on the TTY device. +3. SSH waits for user to enter a password. + +When scripting with Pexpect what can happen is that Pexpect will respond to the +"password:" prompt before SSH has had time to turn off TTY echo. In other words, +Pexpect sends the password between steps 1. and 2., so the password gets echoed +back to the TTY. I would call this an SSH bug. + +Pexpect now automatically adds a short delay before sending data to a child +process. This more closely mimics what happens in the usual human-to-app +interaction. The delay can be tuned with the ``delaybeforesend`` attribute of the +spawn class. In general, this fixes the problem for everyone and so this should +not be an issue for most users. For some applications you might with to turn it +off:: + + child = pexpect.spawn ("ssh user@example.com") + child.delaybeforesend = None + +Truncated output just before child exits +---------------------------------------- + +So far I have seen this only on older versions of Apple's MacOS X. If the child +application quits it may not flush its output buffer. This means that your +Pexpect application will receive an EOF even though it should have received a +little more data before the child died. This is not generally a problem when +talking to interactive child applications. One example where it is a problem is +when trying to read output from a program like *ls*. You may receive most of the +directory listing, but the last few lines will get lost before you receive an EOF. +The reason for this is that *ls* runs; completes its task; and then exits. The +buffer is not flushed before exit so the last few lines are lost. The following +example demonstrates the problem:: + + child = pexpect.spawn('ls -l') + child.expect(pexpect.EOF) + print child.before + +Controlling SSH on Solaris +-------------------------- + +Pexpect does not yet work perfectly on Solaris. One common problem is that SSH +sometimes will not allow TTY password authentication. For example, you may +expect SSH to ask you for a password using code like this:: + + child = pexpect.spawn('ssh user@example.com') + child.expect('password') + child.sendline('mypassword') + +You may see the following error come back from a spawned child SSH:: + + Permission denied (publickey,keyboard-interactive). + +This means that SSH thinks it can't access the TTY to ask you for your password. +The only solution I have found is to use public key authentication with SSH. +This bypasses the need for a password. I'm not happy with this solution.

However, pexpect is under +new maintenance after a long dormancy, so some caution is warranted. + +* A new :ref:`unicode API <unicode>` was introduced. +* Python 3 is now supported, using a single codebase. +* Pexpect now requires at least Python 2.6 or 3.2. +* The modules other than pexpect, such as :mod:`pexpect.fdpexpect` and + :mod:`pexpect.pxssh`, were moved into the pexpect package. For now, wrapper + modules are installed to the old locations for backwards compatibility (e.g. + ``import pxssh`` will still work), but these will be removed at some point in + the future. +* Ignoring ``SIGHUP`` is now optional - thanks to Kimmo Parviainen-Jalanko for + the patch. + +We also now have `docs on ReadTheDocs <https://pexpect.readthedocs.io/>`_, +and `continuous integration on Travis CI <https://travis-ci.org/pexpect/pexpect>`_. + +Version 2.4 +``````````` + +* Fix a bug regarding making the pty the controlling terminal when the process + spawning it is not, actually, a terminal (such as from cron) + +Version 2.3 +``````````` + +* Fixed OSError exception when a pexpect object is cleaned up. Previously, you + might have seen this exception:: + + Exception exceptions.OSError: (10, 'No child processes') + in <bound method spawn.__del__ of <pexpect.spawn instance at 0xd248c>> ignored + + You should not see that anymore. Thanks to Michael Surette. +* Added support for buffering reads. This greatly improves speed when trying to + match long output from a child process. When you create an instance of the spawn + object you can then set a buffer size. For now you MUST do the following to turn + on buffering -- it may be on by default in future version:: + + child = pexpect.spawn ('my_command') + child.maxread=1000 # Sets buffer to 1000 characters. + +* I made a subtle change to the way TIMEOUT and EOF exceptions behave. + Previously you could either expect these states in which case pexpect + will not raise an exception, or you could just let pexpect raise an + exception when these states were encountered. If you expected the + states then the ``before`` property was set to everything before the + state was encountered, but if you let pexpect raise the exception then + ``before`` was not set. Now, the ``before`` property will get set either + way you choose to handle these states. +* The spawn object now provides iterators for a *file-like interface*. + This makes Pexpect a more complete file-like object. You can now write + code like this:: + + child = pexpect.spawn ('ls -l') + for line in child: + print line + +* write and writelines() no longer return a value. Use send() if you need that + functionality. I did this to make the Spawn object more closely match a + file-like object. +* Added the attribute ``exitstatus``. This will give the exit code returned + by the child process. This will be set to ``None`` while the child is still + alive. When ``isalive()`` returns 0 then ``exitstatus`` will be set. +* Made a few more tweaks to ``isalive()`` so that it will operate more + consistently on different platforms. Solaris is the most difficult to support. +* You can now put ``TIMEOUT`` in a list of expected patterns. This is just like + putting ``EOF`` in the pattern list. Expecting for a ``TIMEOUT`` may not be + used as often as ``EOF``, but this makes Pexpect more consistent. +* Thanks to a suggestion and sample code from Chad J. Schroeder I added the ability + for Pexpect to operate on a file descriptor that is already open. This means that + Pexpect can be used to control streams such as those from serial port devices. Now, + you just pass the integer file descriptor as the "command" when constructing a + spawn open. For example on a Linux box with a modem on ttyS1:: + + fd = os.open("/dev/ttyS1", os.O_RDWR|os.O_NONBLOCK|os.O_NOCTTY) + m = pexpect.spawn(fd) # Note integer fd is used instead of usual string. + m.send("+++") # Escape sequence + m.send("ATZ0\r") # Reset modem to profile 0 + rval = m.expect(["OK", "ERROR"]) + +* ``read()`` was renamed to ``read_nonblocking()``. Added new ``read()`` method + that matches file-like object interface. In general, you should not notice + the difference except that ``read()`` no longer allows you to directly set the + timeout value. I hope this will not effect any existing code. Switching to + ``read_nonblocking()`` should fix existing code. +* Changed the name of ``set_echo()`` to ``setecho()``. +* Changed the name of ``send_eof()`` to ``sendeof()``. +* Modified ``kill()`` so that it checks to make sure the pid ``isalive()``. +* modified ``spawn()`` (really called from ``__spawn()``) so that it does not + raise an exception if ``setwinsize()`` fails. Some platforms such as Cygwin + do not like setwinsize. This was a constant problem and since it is not a + critical feature I decided to just silence the error. Normally I don't like + to do that, but in this case I'm making an exception. +* Added a method ``close()`` that does what you think. It closes the file + descriptor of the child application. It makes no attempt to actually kill the + child or wait for its status. +* Add variables ``__version__`` and ``__revision__`` (from cvs) to the pexpect + modules. This is mainly helpful to me so that I can make sure that I'm testing + with the right version instead of one already installed. +* ``log_open()`` and ``log_close(`` have been removed. Now use ``setlog()``. + The ``setlog()`` method takes a file object. This is far more flexible than + the previous log method. Each time data is written to the file object it will + be flushed. To turn logging off simply call ``setlog()`` with None. +* renamed the ``isAlive()`` method to ``isalive()`` to match the more typical + naming style in Python. Also the technique used to detect child process + status has been drastically modified. Previously I did some funky stuff + with signals which caused indigestion in other Python modules on some + platforms. It was a big headache. It still is, but I think it works + better now. +* attribute ``matched`` renamed to ``after`` +* new attribute ``match`` +* The ``expect_eof()`` method is gone. You can now simply use the + ``expect()`` method to look for EOF. +* **Pexpect works on OS X**, but the nature of the quirks cause many of the + tests to fail. See bugs. (Incomplete Child Output). The problem is more + than minor, but Pexpect is still more than useful for most tasks. +* **Solaris**: For some reason, the *second* time a pty file descriptor is created and + deleted it never gets returned for use. It does not effect the first time + or the third time or any time after that. It's only the second time. This + is weird... This could be a file descriptor leak, or it could be some + peculiarity of how Solaris recycles them.

You can use this technique with any application. +This is especially handy if you are writing automated test tools. + +There are two important methods in Pexpect -- :meth:`~pexpect.spawn.expect` and +:meth:`~pexpect.spawn.send` (or :meth:`~pexpect.spawn.sendline` which is +like :meth:`~pexpect.spawn.send` with a linefeed). The :meth:`~pexpect.spawn.expect` +method waits for the child application to return a given string. The string you +specify is a regular expression, so you can match complicated patterns. The +:meth:`~pexpect.spawn.send` method writes a string to the child application. +From the child's point of view it looks just like someone typed the text from a +terminal. After each call to :meth:`~pexpect.spawn.expect` the ``before`` and ``after`` +properties will be set to the text printed by child application. The ``before`` +property will contain all text up to the expected string pattern. The ``after`` +string will contain the text that was matched by the expected pattern. +The match property is set to the `re match object <http://docs.python.org/3/library/re#match-objects>`_. + +An example of Pexpect in action may make things more clear. This example uses +ftp to login to the OpenBSD site; list files in a directory; and then pass +interactive control of the ftp session to the human user:: + + import pexpect + child = pexpect.spawn ('ftp ftp.openbsd.org') + child.expect ('Name .*: ') + child.sendline ('anonymous') + child.expect ('Password:') + child.sendline ('noah@example.com') + child.expect ('ftp> ') + child.sendline ('ls /pub/OpenBSD/') + child.expect ('ftp> ') + print child.before # Print the result of the ls command. + child.interact() # Give control of the child to the user. + +Special EOF and TIMEOUT patterns +-------------------------------- + +There are two special patterns to match the End Of File (:class:`~pexpect.EOF`) +or a Timeout condition (:class:`~pexpect.TIMEOUT`). You can pass these +patterns to :meth:`~pexpect.spawn.expect`. These patterns are not regular +expressions. Use them like predefined constants. + +If the child has died and you have read all the child's output then ordinarily +:meth:`~pexpect.spawn.expect` will raise an :class:`~pexpect.EOF` exception. +You can read everything up to the EOF without generating an exception by using +the EOF pattern expect. In this case everything the child has output will be +available in the ``before`` property. + +The pattern given to :meth:`~pexpect.spawn.expect` may be a regular expression +or it may also be a list of regular expressions. This allows you to match +multiple optional responses. The :meth:`~pexpect.spawn.expect` method returns +the index of the pattern that was matched. For example, say you wanted to login +to a server. After entering a password you could get various responses from the +server -- your password could be rejected; or you could be allowed in and asked +for your terminal type; or you could be let right in and given a command prompt. +The following code fragment gives an example of this:: + + child.expect('password:') + child.sendline(my_secret_password) + # We expect any of these three patterns... + i = child.expect (['Permission denied', 'Terminal type', '[#\$] ']) + if i==0: + print('Permission denied on host. Can\'t login') + child.kill(0) + elif i==1: + print('Login OK... need to send terminal type.') + child.sendline('vt100') + child.expect('[#\$] ') + elif i==2: + print('Login OK.') + print('Shell command prompt', child.after) + +If nothing matches an expected pattern then :meth:`~pexpect.spawn.expect` will +eventually raise a :class:`~pexpect.TIMEOUT` exception. The default time is 30 +seconds, but you can change this by passing a timeout argument to +:meth:`~pexpect.spawn.expect`:: + + # Wait no more than 2 minutes (120 seconds) for password prompt. + child.expect('password:', timeout=120) + +Find the end of line -- CR/LF conventions +----------------------------------------- + +Pexpect matches regular expressions a little differently than what you might be +used to. + +The :regexp:`$` pattern for end of line match is useless. The :regexp:`$` +matches the end of string, but Pexpect reads from the child one character at a +time, so each character looks like the end of a line. Pexpect can't do a +look-ahead into the child's output stream. In general you would have this +situation when using regular expressions with any stream. + +.. note:: + + Pexpect does have an internal buffer, so reads are faster than one character + at a time, but from the user's perspective the regex patterns test happens + one character at a time. + +The best way to match the end of a line is to look for the newline: ``"\r\n"`` +(CR/LF). Yes, that does appear to be DOS-style. It may surprise some UNIX people +to learn that terminal TTY device drivers (dumb, vt100, ANSI, xterm, etc.) all +use the CR/LF combination to signify the end of line. Pexpect uses a Pseudo-TTY +device to talk to the child application, so when the child app prints ``"\n"`` +you actually see ``"\r\n"``. + +UNIX uses just linefeeds to end lines of text, but not when it comes to TTY +devices! TTY devices are more like the Windows world. Each line of text ends +with a CR/LF combination. When you intercept data from a UNIX command from a +TTY device you will find that the TTY device outputs a CR/LF combination. A +UNIX command may only write a linefeed (``\n``), but the TTY device driver +converts it to CR/LF. This means that your terminal will see lines end with +CR/LF (hex ``0D 0A``). Since Pexpect emulates a terminal, to match ends of +lines you have to expect the CR/LF combination:: + + child.expect('\r\n') + +If you just need to skip past a new line then ``expect('\n')`` by itself will +work, but if you are expecting a specific pattern before the end of line then +you need to explicitly look for the ``\r``. For example the following expects a +word at the end of a line:: + + child.expect('\w+\r\n') + +But the following would both fail:: + + child.expect('\w+\n') + +And as explained before, trying to use :regexp:`$` to match the end of line +would not work either:: + + child.expect ('\w+$') + +So if you need to explicitly look for the END OF LINE, you want to look for the +CR/LF combination -- not just the LF and not the $ pattern. + +This problem is not limited to Pexpect. This problem happens any time you try +to perform a regular expression match on a stream. Regular expressions need to +look ahead. With a stream it is hard to look ahead because the process +generating the stream may not be finished. There is no way to know if the +process has paused momentarily or is finished and waiting for you. Pexpect must +implicitly always do a NON greedy match (minimal) at the end of a input. + +Pexpect compiles all regular expressions with the :data:`re.DOTALL` flag. +With the :data:`~re.DOTALL` flag, a ``"."`` will match a newline. + +Beware of + and * at the end of patterns +---------------------------------------- + +Remember that any time you try to match a pattern that needs look-ahead that +you will always get a minimal match (non greedy). For example, the following +will always return just one character:: + + child.expect ('.+') + +This example will match successfully, but will always return no characters:: + + child.expect ('.*') + +Generally any star * expression will match as little as possible. + +One thing you can do is to try to force a non-ambiguous character at the end of +your :regexp:`\\d+` pattern. Expect that character to delimit the string. For +example, you might try making the end of your pattern be :regexp:`\\D+` instead +of :regexp:`\\D*`. Number digits alone would not satisfy the :regexp:`(\\d+)\\D+` +pattern. You would need some numbers and at least one non-number at the end. + + +Debugging +--------- + +If you get the string value of a :class:`pexpect.spawn` object you will get lots +of useful debugging information. For debugging it's very useful to use the +following pattern:: + + try: + i = child.expect ([pattern1, pattern2, pattern3, etc]) + except: + print("Exception was thrown") + print("debug information:") + print(str(child)) + +It is also useful to log the child's input and out to a file or the screen. The +following will turn on logging and send output to stdout (the screen):: + + child = pexpect.spawn(foo) + child.logfile = sys.stdout + +Exceptions +---------- + +:class:`~pexpect.EOF` + +Note that two flavors of EOF Exception may be thrown. They are virtually +identical except for the message string. For practical purposes you should have +no need to distinguish between them, but they do give a little extra information +about what type of platform you are running. The two messages are: + +- "End Of File (EOF) in read(). Exception style platform." +- "End Of File (EOF) in read(). Empty string style platform." + +Some UNIX platforms will throw an exception when you try to read from a file +descriptor in the EOF state. Other UNIX platforms instead quietly return an +empty string to indicate that the EOF state has been reached. + +If you wish to read up to the end of the child's output without generating an +:class:`~pexpect.EOF` exception then use the ``expect(pexpect.EOF)`` method. + +:class:`~pexpect.TIMEOUT` + +The :meth:`~pexpect.spawn.expect` and :meth:`~pexpect.spawn.read` methods will +also timeout if the child does not generate any output for a given amount of +time. If this happens they will raise a :class:`~pexpect.TIMEOUT` exception. +You can have these methods ignore timeout and block indefinitely by passing +``None`` for the timeout parameter:: + + child.expect(pexpect.EOF, timeout=None) + +.. _windows: + +Pexpect on Windows +------------------ + +.. versionadded:: 4.0 + Windows support + +Pexpect can be used on Windows to wait for a pattern to be produced by a child +process, using :class:`pexpect.popen_spawn.PopenSpawn`, or a file descriptor, +using :class:`pexpect.fdpexpect.fdspawn`. + +:class:`pexpect.spawn` and :func:`pexpect.run` are *not* available on Windows, +as they rely on Unix pseudoterminals (ptys).

It +can be used for automated software testing. Pexpect is in the spirit of Don +Libes' Expect, but Pexpect is pure Python. Other Expect-like modules for Python +require TCL and Expect or require C extensions to be compiled. Pexpect does not +use C, Expect, or TCL extensions.

The spawn class is more powerful. The run() +function is simpler than spawn, and is good for quickly calling program.

This is a handy replacement for os.system(). + +For example:: + + pexpect.run('ls -la') + +The spawn class is the more powerful interface to the Pexpect system.

The logfile is flushed after each write. + + Example log input and output to a file:: + + child = pexpect.spawn('some_command') + fout = open('mylog.txt','wb') + child.logfile = fout + + Example log to stdout:: + + # In Python 2: + child = pexpect.spawn('some_command') + child.logfile = sys.stdout + + # In Python 3, we'll use the ``encoding`` argument to decode data + # from the subprocess and handle it as unicode: + child = pexpect.spawn('some_command', encoding='utf-8') + child.logfile = sys.stdout + + The logfile_read and logfile_send members can be used to separately log + the input from the child and output sent to the child. Sometimes you + don't want to see everything you write to the child. You only want to + log what the child sends back. For example:: + + child = pexpect.spawn('some_command') + child.logfile_read = sys.stdout + + You will need to pass an encoding to spawn in the above code if you are + using Python 3. + + To separately log output sent to the child use logfile_send:: + + child.logfile_send = fout + + If ``ignore_sighup`` is True, the child process will ignore SIGHUP + signals. The default is False from Pexpect 4.0, meaning that SIGHUP + will be handled normally by the child. + + The delaybeforesend helps overcome a weird behavior that many users + were experiencing. The typical problem was that a user would expect() a + "Password:" prompt and then immediately call sendline() to send the + password. The user would then see that their password was echoed back + to them. Passwords don't normally echo. The problem is caused by the + fact that most applications print out the "Password" prompt and then + turn off stdin echo, but if you send your password before the + application turned off echo, then you get your password echoed. + Normally this wouldn't be a problem when interacting with a human at a + real keyboard. If you introduce a slight delay just before writing then + this seems to clear up the problem. This was such a common problem for + many users that I decided that the default pexpect behavior should be + to sleep just before writing to the child application. 1/20th of a + second (50 ms) seems to be enough to clear up the problem. You can set + delaybeforesend to None to return to the old behavior. + + Note that spawn is clever about finding commands on your path. + It uses the same logic that "which" uses to find executables. + + If you wish to get the exit status of the child you must call the + close() method. The exit or signal status of the child will be stored + in self.exitstatus or self.signalstatus. If the child exited normally + then exitstatus will store the exit return code and signalstatus will + be None. If the child was terminated abnormally with a signal then + signalstatus will store the signal value and exitstatus will be None:: + + child = pexpect.spawn('some_command') + child.close() + print(child.exitstatus, child.signalstatus) + + If you need more detail you can also read the self.status member which + stores the status returned by os.waitpid. You can interpret this using + os.WIFEXITED/os.WEXITSTATUS or os.WIFSIGNALED/os.TERMSIG. + + The echo attribute may be set to False to disable echoing of input. + As a pseudo-terminal, all input echoed by the "keyboard" (send() + or sendline()) will be repeated to output. For many cases, it is + not desirable to have echo enabled, and it may be later disabled + using setecho(False) followed by waitnoecho(). However, for some + platforms such as Solaris, this is not possible, and should be + disabled immediately on spawn. + + If preexec_fn is given, it will be called in the child process before + launching the given command. This is useful to e.g. reset inherited + signal handlers. + + The dimensions attribute specifies the size of the pseudo-terminal as + seen by the subprocess, and is specified as a two-entry tuple (rows, + columns). If this is unspecified, the defaults in ptyprocess will apply. + + The use_poll attribute enables using select.poll() over select.select() + for socket handling.

If you set + 'withexitstatus' to true, then run will return a tuple of (command_output, + exitstatus). If 'withexitstatus' is false then this returns just + command_output. + + The run() function can often be used instead of creating a spawn instance. + For example, the following code uses spawn:: + + from pexpect import * + child = spawn('scp foo user@example.com:.') + child.expect('(?i)password') + child.sendline(mypassword) + + The previous code can be replace with the following:: + + from pexpect import * + run('scp foo user@example.com:.', events={'(?i)password': mypassword}) + + **Examples** + + Start the apache daemon on the local machine:: + + from pexpect import * + run("/usr/local/apache/bin/apachectl start") + + Check in a file using SVN:: + + from pexpect import * + run("svn ci -m 'automatic commit' my_file.py") + + Run a command and capture exit status:: + + from pexpect import * + (command_output, exitstatus) = run('ls -l /bin', withexitstatus=1) + + The following will run SSH and execute 'ls -l' on the remote machine. The + password 'secret' will be sent if the '(?i)password' pattern is ever seen:: + + run("ssh username@machine.example.com 'ls -l'", + events={'(?i)password':'secret\\n'}) + + This will start mencoder to rip a video from DVD. This will also display + progress ticks every 5 seconds as it runs. For example:: + + from pexpect import * + def print_ticks(d): + print d['event_count'], + run("mencoder dvd://1 -o video.avi -oac copy -ovc copy", + events={TIMEOUT:print_ticks}, timeout=5) + + The 'events' argument should be either a dictionary or a tuple list that + contains patterns and responses. Whenever one of the patterns is seen + in the command output, run() will send the associated response string. + So, run() in the above example can be also written as: + + run("mencoder dvd://1 -o video.avi -oac copy -ovc copy", + events=[(TIMEOUT,print_ticks)], timeout=5) + + Use a tuple list for events if the command output requires a delicate + control over what pattern should be matched, since the tuple list is passed + to pexpect() as its pattern list, with the order of patterns preserved. + + Note that you should put newlines in your string if Enter is necessary. + + Like the example above, the responses may also contain a callback, either + a function or method. It should accept a dictionary value as an argument. + The dictionary contains all the locals from the run() function, so you can + access the child spawn object or any other variable defined in run() + (event_count, child, and extra_args are the most useful). A callback may + return True to stop the current run process. Otherwise run() continues + until the next event. A callback may also return a string which will be + sent to the child. 'extra_args' is not used by directly run(). It provides + a way to pass data to a callback function through run() through the locals + dictionary passed to a callback. + + Like :class:`spawn`, passing *encoding* will make it work with unicode + instead of bytes. You can pass *codec_errors* to control how errors in + encoding and decoding are handled. + ''' + if timeout == -1: + child = spawn(command, maxread=2000, logfile=logfile, cwd=cwd, env=env, + **kwargs) + else: + child = spawn(command, timeout=timeout, maxread=2000, logfile=logfile, + cwd=cwd, env=env, **kwargs) + if isinstance(events, list): + patterns= [x for x,y in events] + responses = [y for x,y in events] + elif isinstance(events, dict): + patterns = list(events.keys()) + responses = list(events.values()) + else: + # This assumes EOF or TIMEOUT will eventually cause run to terminate. + patterns = None + responses = None + child_result_list = [] + event_count = 0 + while True: + try: + index = child.expect(patterns) + if isinstance(child.after, child.allowed_string_types): + child_result_list.append(child.before + child.after) + else: + # child.after may have been a TIMEOUT or EOF, + # which we don't want appended to the list. + child_result_list.append(child.before) + if isinstance(responses[index], child.allowed_string_types): + child.send(responses[index]) + elif (isinstance(responses[index], types.FunctionType) or + isinstance(responses[index], types.MethodType)): + callback_result = responses[index](locals()) + sys.stdout.flush() + if isinstance(callback_result, child.allowed_string_types): + child.send(callback_result) + elif callback_result: + break + else: + raise TypeError("parameter `event' at index {index} must be " + "a string, method, or function: {value!r}" + .format(index=index, value=responses[index])) + event_count = event_count + 1 + except TIMEOUT: + child_result_list.append(child.before) + break + except EOF: + child_result_list.append(child.before) + break + child_result = child.string_type().join(child_result_list) + if withexitstatus: + child.close() + return (child_result, child.exitstatus) + else: + return child_result + +def runu(command, timeout=30, withexitstatus=False, events=None, + extra_args=None, logfile=None, cwd=None, env=None, **kwargs): + """Deprecated: pass encoding to run() instead. + """ + kwargs.setdefault('encoding', 'utf-8') + return run(command, timeout=timeout, withexitstatus=withexitstatus, + events=events, extra_args=extra_args, logfile=logfile, cwd=cwd, + env=env, **kwargs) diff --git a/lldb/third_party/Python/module/pexpect-4.6/pexpect/screen.py b/lldb/third_party/Python/module/pexpect-4.6/pexpect/screen.py new file mode 100644 index 000000000000..5ab45b946795 --- /dev/null +++ b/lldb/third_party/Python/module/pexpect-4.6/pexpect/screen.py @@ -0,0 +1,431 @@ +'''This implements a virtual screen.

For example:: + + # the input is 'foobar' + index = p.expect(['foobar', 'foo']) + # returns 0('foobar') if all input is available at once, + # but returns 1('foo') if parts of the final 'bar' arrive late + + When a match is found for the given pattern, the class instance + attribute *match* becomes an re.MatchObject result. Should an EOF + or TIMEOUT pattern match, then the match attribute will be an instance + of that exception class. The pairing before and after class + instance attributes are views of the data preceding and following + the matching pattern. On general exception, class attribute + *before* is all data received up to the exception, while *match* and + *after* attributes are value None. + + When the keyword argument timeout is -1 (default), then TIMEOUT will + raise after the default value specified by the class timeout + attribute. When None, TIMEOUT will not be raised and may block + indefinitely until match. + + When the keyword argument searchwindowsize is -1 (default), then the + value specified by the class maxread attribute is used. + + A list entry may be EOF or TIMEOUT instead of a string. This will + catch these exceptions and return the index of the list entry instead + of raising the exception. The attribute 'after' will be set to the + exception type. The attribute 'match' will be None. This allows you to + write code like this:: + + index = p.expect(['good', 'bad', pexpect.EOF, pexpect.TIMEOUT]) + if index == 0: + do_something() + elif index == 1: + do_something_else() + elif index == 2: + do_some_other_thing() + elif index == 3: + do_something_completely_different() + + instead of code like this:: + + try: + index = p.expect(['good', 'bad']) + if index == 0: + do_something() + elif index == 1: + do_something_else() + except EOF: + do_some_other_thing() + except TIMEOUT: + do_something_completely_different() + + These two forms are equivalent. It all depends on what you want. You + can also just expect the EOF if you are waiting for all output of a + child to finish. For example:: + + p = pexpect.spawn('/bin/ls') + p.expect(pexpect.EOF) + print p.before + + If you are trying to optimize for speed then see expect_list(). + + On Python 3.4, or Python 3.3 with asyncio installed, passing + ``async_=True`` will make this return an :mod:`asyncio` coroutine, + which you can yield from to get the same result that this method would + normally give directly.

api + +What is a pty? +-------------- + +A pty is a kernel-level object which processes can write data to and read data +from, a bit like a pipe. + +Unlike a pipe, data moves through a single pty in both directions. When you use +a program in a shell pipeline, or with :class:`subprocess.Popen` in Python, up +to three pipes are created for the process's standard streams (stdin, stdout +and stderr). When you run a program using ptyprocess, all three of its standard +streams are connected to a single pty: + +.. image:: images/pty_vs_popen.png + +A pty also does more than a pipe. It keeps track of the window size (rows and +columns of characters) and notifies child processes (with a SIGWINCH signal) +when it changes. In *cooked mode*, it does some processing of data sent from the +parent process, so for instance the byte ``03`` (entered as Ctrl-C) will cause +SIGINT to be sent to the child process. + +Many command line programs behave differently if they detect that stdin or stdout +is connected to a terminal instead of a pipe (using +`isatty() <http://linux.die.net/man/3/isatty>`_), because this normally means +that they're being used interactively by a human user. +They may format output differently (e.g. ``ls`` lists files in columns) +or prompt the user to confirm actions. +When you run these programs in ptyprocess, they will exhibit their 'interactive' +behaviour, instead of the 'pipe' behaviour you'll see using ``Popen()``. + +.. seealso:: + + `The TTY demystified <http://www.linusakesson.net/programming/tty/>`_ + Detailed article by Linus Akesson + +Indices and tables +================== + +* :ref:`genindex` +* :ref:`modindex` +* :ref:`search` + diff --git a/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/__init__.py b/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/__init__.py new file mode 100644 index 000000000000..e633d0cddacd --- /dev/null +++ b/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/__init__.py @@ -0,0 +1,4 @@ +"""Run a subprocess in a pseudo terminal""" +from .ptyprocess import PtyProcess, PtyProcessUnicode, PtyProcessError + +__version__ = '0.6.0' diff --git a/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/_fork_pty.py b/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/_fork_pty.py new file mode 100644 index 000000000000..a8d05fe5a3d1 --- /dev/null +++ b/lldb/third_party/Python/module/ptyprocess-0.6.0/ptyprocess/_fork_pty.py @@ -0,0 +1,78 @@ +"""Substitute for the forkpty system call, to support Solaris. +""" +import os +import errno + +from pty import (STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO, CHILD) +from .util import PtyProcessError + +def fork_pty(): + '''This implements a substitute for the forkpty system call.
