• Java Process.waitFor() and IO streams

  - by lynks

  I have the following code; String[] cmd = { "bash", "-c", "~/path/to/script.sh" }; Process p = Runtime.getRuntime().exec(cmd); PipeThread a = new PipeThread(p.getInputStream(), System.out); PipeThread b = new PipeThread(p.getErrorStream(), System.err); p.waitFor(); a.die(); b.die(); The PipeThread class is quite simple so I will include it in full; public class PipeThread implements Runnable { private BufferedInputStream in; private BufferedOutputStream out; public Thread thread; private boolean die = false; public PipeThread(InputStream i, OutputStream o) { in = new BufferedInputStream(i); out = new BufferedOutputStream(o); thread = new Thread(this); thread.start(); } public void die() { die = true; } public void run() { try { byte[] b = new byte[1024]; while(!die) { int x = in.read(b, 0, 1024); if(x > 0) out.write(b, 0, x); else die(); out.flush(); } } catch(Exception e) { e.printStackTrace(); } try { in.close(); out.close(); } catch(Exception e) { } } } My problem is this; p.waitFor() blocks endlessly, even after the subprocess has terminated. If I do not create the pair of PipeThread instances, then p.waitFor() works perfectly. What is it about the piping of io streams that is causing p.waitFor() to continue blocking? I'm confused as I thought the IO streams would be passive, unable to keep a process alive, or to make Java think the process is still alive.

• An Interactive Console I/O Wrapper/Interceptor in C# - What is the issue?

  - by amazedsaint

  I was trying to put together an interactive Console interceptor/wrapper in C# over the weekend, by re-mixing few code samples I've found in SO and other sites. With what I've as of now, I'm unable to read back from the console reliably. Any quick pointers? public class ConsoleInterceptor { Process _interProc; public event Action<string> OutputReceivedEvent; public ConsoleInterceptor() { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo("cmd"); InitializeInterpreter(); } public ConsoleInterceptor(string command) { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo(command); InitializeInterpreter(); } public Process InterProc { get { return _interProc; } } private void InitializeInterpreter() { InterProc.StartInfo.RedirectStandardInput = true; InterProc.StartInfo.RedirectStandardOutput = true; InterProc.StartInfo.RedirectStandardError = true; InterProc.StartInfo.CreateNoWindow = true; InterProc.StartInfo.UseShellExecute = false; InterProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; bool started = InterProc.Start(); Redirect(InterProc.StandardOutput); Redirect(InterProc.StandardError); } private void Redirect(StreamReader input) { new Thread((a) => { var buffer = new char[1]; while (true) { if (input.Read(buffer, 0, 1) > 0) OutputReceived(new string(buffer)); }; }).Start(); } private void OutputReceived(string text) { if (OutputReceivedEvent != null) OutputReceivedEvent(text); } public void Input(string input) { InterProc.StandardInput.WriteLine(input); InterProc.StandardInput.Flush(); } }

• Python GUI does not update until entire process is finished

  - by ccwhite1

  I have a process that gets a files from a directory and puts them in a list. It then iterates that list in a loop. The last line of the loop being where it should update my gui display, then it begins the loop again with the next item in the list. My problem is that it does not actually update the gui until the entire process is complete, which depending on the size of the list could be 30 seconds to over a minute. This gives the feeling of the program being 'hung' What I wanted it to do was to process one line in the list, update the gui and then continue. Where did I go wrong? The line to update the list is # Populate listview with drive contents. The print statements are just for debug. def populateList(self): print "populateList" sSource = self.txSource.Value sDest = self.txDest.Value # re-intialize listview and validated list self.listView1.DeleteAllItems() self.validatedMove = None self.validatedMove = [] #Create list of files listOfFiles = getList(sSource) #prompt if no files detected if listOfFiles == []: self.lvActions.Append([datetime.datetime.now(),"Parse Source for .MP3 files","No .MP3 files in source directory"]) #Populate list after both Source and Dest are chosen if len(sDest) > 1 and len(sDest) > 1: print "-iterate listOfFiles" for file in listOfFiles: sFilename = os.path.basename(file) sTitle = getTitle(file) sArtist = getArtist(file) sAlbum = getAblum(file) # Make path = sDest + Artist + Album sDestDir = os.path.join (sDest, sArtist) sDestDir = os.path.join (sDestDir, sAlbum) #If file exists change destination to *.copyX.mp3 sDestDir = self.defineDestFilename(os.path.join(sDestDir,sFilename)) # Populate listview with drive contents self.listView1.Append([sFilename,sTitle,sArtist,sAlbum,sDestDir]) #populate list to later use in move command self.validatedMove.append([file,sDestDir]) print "-item added to SourceDest list" else: print "-list not iterated"

• deleting cookie at the end of a process

  - by RyanP13

  Hi, I am using the following plug in for cookies in jQuery: https://code.google.com/p/cookies/ The issue i am having is not with the plugin but when and how to delete the cookie at the end of a quoting process. The site i am using this on is a six step online quote and buy process. There is Omniture event serialisation sitestat tracking applied to some of the pages. This event serialisation has to include the name of the event and a random number of which i create. I have a generic function for this which i call at the bottom of the page like so: serialEvent('event21:', 'payment'); Here is the function: function serialEvent(eventNumber, eventName) { var sessionID = jaaulde.utils.cookies.get('sessionID'); var remLength = 20 - eventName.length; var remSession = sessionID.substr(sessionID.length - remLength, remLength); var eventName = eventName + remSession; s.events = eventNumber + eventName; } I need to delete the cookie at the end of the process, the Thank you page but i also need the cookie 'sessionID' for the 'serialEvent' function. As the function is called at the bottom of the page should i just write the cookie delete after it? Is that robust enough? I need to be sure that the function has successfully been called before the cookie is deleted. The code for deleting the cookie is quite simple: jaaulde.utils.cookies.del('sessionID'); Thanks :)

• Multi-core processors: Better performance running multiple applications?

  - by aip.cd.aish

  I realize for single applications - the application itself has to be designed to take advantage of multiple cores. But what about executing many different applications simultaneously? On my development machine at an average instance, I run multiple servers (a database server, a web server), multiple instance of IDEs (either Visual Studio or NetBeans), Web-browser with multiple tabs (in Chrome, each tab is a process on its own), FTP client, SSH client etc. Does having a multi-core system improve the ability to run multiple applications simultaneously?

• Alternative of procman in linux

  - by shadyabhi

  I want a program which gives all information relating to a currently running process. In Windows, there is procman . Whats the alternative in LINUX? Do i have to use tools like strace etc seperately, or there is one program that does all. Do share if you know of a nice software.

• How can I see processes running in Windows 7?

  - by Roman

  I found the following sentence: Many Windows-Users may have wondered about the mDNSResponder.exe process running all the time. It’s Bonjour. Does anybody know how can I see these processes (I do not mean "mDNSResponder.exe". I mean in general.). It should be some analog of "top" command in Linux.

• Application process never terminates on each run

  - by rockyurock

  I am seeing an application always remains live even after closing the application using my Perl script below. Also, for the subsequent runs, it always says that "The process cannot access the file because it is being used by another process. iperf.exe -u -s -p 5001 successful. Output was:" So every time I have to change the file name $file used in script or I have to kill the iperf.exe process in the Task Manager. Could anybody please let me know the way to get rid of it? Here is the code I am using ... my @command_output; eval { my $file = "abc6.txt"; $command = "iperf.exe -u -s -p 5001"; alarm 10; system("$command > $file"); alarm 0; close $file; }; if ($@) { warn "$command timed out.\n"; } else { print "$command successful. Output was:\n", $file; } unlink $file;

• How to copy files without slowing down my app?

  - by Kevin Gebhardt

  I have a bunch of little files in my assets which need to be copied to the SD-card on the first start of my App. The copy code i got from here placed in an IntentService works like a charm. However, when I start to copy many litte files, the whole app gets increddible slow (I'm not really sure why by the way), which is a really bad experience for the user on first start. As I realised other apps running normal in that time, I tried to start a child process for the service, which didn't work, as I can't acess my assets from another process as far as I understood. Has anybody out there an idea how a) to copy the files without blocking my app b) to get through to my assets from a private process (process=":myOtherProcess" in Manifest) or c) solve the problem in a complete different way Edit: To make this clearer: The copying allready takes place in a seperate thread (started automaticaly by IntentService). The problem is not to separate the task of copying but that the copying in a dedicated thread somehow affects the rest of the app (e.g. blocking to many app-specific resources?) but not other apps (so it's not blocking the whole CPU or someting) Edit2: Problem solved, it turns out, there wasn't really a problem. See my answer below.

• How to cancel a deeply nested process

  - by Mystere Man

  I have a class that is a "manager" sort of class. One of it's functions is to signal that the long running process of the class should shut down. It does this by setting a boolean called "IsStopping" in class. public class Foo { bool isStoping void DoWork() { while (!isStopping) { // do work... } } } Now, DoWork() was a gigantic function, and I decided to refactor it out and as part of the process broke some of it into other classes. The problem is, Some of these classes also have long running functions that need to check if isStopping is true. public class Foo { bool isStoping void DoWork() { while (!isStopping) { MoreWork mw = new MoreWork() mw.DoMoreWork() // possibly long running // do work... } } } What are my options here? I have considered passing isStopping by reference, which I don't really like because it requires there to be an outside object. I would prefer to make the additional classes as stand alone and dependancy free as possible. I have also considered making isStopping a property, and then then having it call an event that the inner classes could be subscribed to, but this seems overly complex. Another option was to create a "Process Cancelation Token" class, similar to what .net 4 Tasks use, then that token be passed to those classes. How have you handled this situation? EDIT: Also consider that MoreWork might have a EvenMoreWork object that it instantiates and calls a potentially long running method on... and so on. I guess what i'm looking for is a way to be able to signal an arbitrary number of objects down a call tree to tell them to stop what they're doing and clean up and return.

• Tracking down origin of I/O in multi-process server

  - by Craig Ringer

  I'm currently trying to track down some phantom I/O in a PostgreSQL build I'm testing. It's a multi-process server and it isn't simple to associate disk I/O back to a particular back-end and query. I thought Linux's perf tool would be ideal for this, but I'm struggling to capture block I/O performance counter metrics and associate them with user-space activity. It's easy to record block I/O requests and completions with, eg: sudo perf record -g -T -u postgres -e 'block:block_rq_*' and the user-space pid is recorded, but there's no kernel or user-space stack captured, or ability to snapshot bits of the user-space process's heap (say, query text) etc. So while you have the pid, you don't know what the process was doing at that point. Just perf script output like: postgres 7462 [002] 301125.113632: block:block_rq_issue: 8,0 W 0 () 208078848 + 1024 [postgres] If I add the -g flag to perf record it'll take snapshots of the kernel stack, but doesn't capture user-space state for perf events captured in the kernel. The user-space stack only goes up to the entry-point from userspace, like LWLockRelease, LWLockAcquire, memcpy (mmap'd IO), __GI___libc_write, etc. So. Any tips? Being able to capture a snapshot of the user-space stack in response to kernel events would be ideal.

• Creating a MiniDump of a running process

• .NET StandardInput Sending Modifiers

  - by Paul Oakham

  We have some legacy software which depends on sending keystrokes to a DOS window and then scraping the screen. I am trying to re-create the software by redirecting the input and output streams of the process directly to my application. This part I have managed fine using: _Process = new Process(); { _Process.StartInfo.FileName = APPLICATION; _Process.StartInfo.RedirectStandardOutput = true; _Process.StartInfo.RedirectStandardInput = true; _Process.StartInfo.RedirectStandardError = true; _Process.StartInfo.UseShellExecute = false; _Process.StartInfo.CreateNoWindow = true; _Process.OutputDataReceived += new DataReceivedEventHandler(_Process_OutputDataReceived); _Process.ErrorDataReceived += new DataReceivedEventHandler(_Process_ErrorDataReceived); } My problem is I need to send some command modifiers such as Ctrl, ALT and Space as well as F1-12 to this process but am unsure how. I can send basic text and I receive response's fine. I just need to emulate these modifiers.

• Problems with CloseMainWindow() to close a Windows Explorer window

  Hello! I´m facing a problem when trying to close a Windows Explorer (not Internet Explorer) window through another application, using the "Process.CloseMainWindow()" method; because it doesn´t close the Explorer window, it tries to close the full Windows (Operative System), by the way, Windows XP. The code is as follows: [DllImport("user32.dll")] static extern int GetForegroundWindow(); [DllImport("user32.dll")] private static extern UInt32 GetWindowThreadProcessId(Int32 hWnd, out Int32 lpdwProcessId); public String[] exeCommand() { try { //Get App Int32 hwnd = 0; hwnd = GetForegroundWindow(); Process actualProcess = Process.GetProcessById(GetWindowProcessID(hwnd)); //Close App if (!actualProcess.CloseMainWindow()) actualProcess.Kill(); } catch { throw; } return null; } Suppose that the "actualProcess" is "explorer.exe" Any help will be appreciated!!

• Recommended way to manage persistent PHP script processes?

  - by BigglesZX

  First off - hello, this is my first Stack Overflow question so I'll try my best to communicate properly. The title of my question may be a bit ambiguous so let me expand upon it immediately: I'm planning a project which involves taking data inputs from several "streaming" APIs, Twitter being one example. I've got a basic script coded up in PHP which runs indefinitely from the command line, taking input from the Twitter streaming API and doing very basic things with it. My eventual objective is to have several such processes running (perhaps daemonized using the System Daemon PEAR class), and I would like to be able to manage them from some governing process (also a PHP script). By manage I mean basic operations such as stop/start and (most crucially) automatically restarting a process that crashes. I would appreciate any pointers on how best to approach this process management angle. Again, apologies if this question is too expansive - tips on more tightly focused lines of enquiry would be appreciated if necessary. Thanks for reading and I look forward to your answers.

• How to auto-restart a python script on fail?

  - by norm

  This post describes how to keep a child process alive in a BASH script: http://stackoverflow.com/questions/696839/how-do-i-write-a-bash-script-to-restart-a-process-if-it-dies This worked great for calling another BASH script. However, I tried executing something similar where the child process is a Python script: #!/bin/bash PYTHON=/usr/bin/python2.6 function myprocess { $PYTHON daemon.py start } NOW=$(date +"%b-%d-%y") until myprocess; do echo "$NOW Prog crashed. Restarting..." >> error.txt sleep 1 done Now the behaviour is completely different. It seems the python script is no longer a child of of the bash script but seems to have 'taken over' the BASH scripts PID - so there is no longer a BASH wrapper round the called script...why?

• C# Monitor Programs Periodically Based on PID

  - by ThaKidd

  Thank you in advance for you ideas and input. I would like to periodically check to see if a third party program is currently running on a user's system from my program. I am currently launching the program as follows in C#: String plinkConString = ""; // my connection string Process plink = Process.Start(utilityPath + @"\putty.exe", plinkConString); int plinkProcessId = plink.Id; I launch the program and grab its pid in a Windows environment. As Putty/PLink may disconnect from its SSH server at some point and close, what is the best way to monitor how this process is doing in code? Is there a better way to launch this program to monitor its success or failure?

• c#: RedirectStandardOutput prevents exit exception?

  - by user1743977

  All I want is to redirect standard output of a process to a file. Sounds easy, but everything I tried doesn't work: 1) putting a dos-style redirection in the list of arguments (e.g. "param1 param2 output.txt") doesn't work, 2) using RedirectStandardOutput = true works, BUT, apparently the process does not through an exception when it exists. So the handler defined via process.Exited += ... doesn't catch anything. To be clear, once I remove the 'RedirectStandardOutput = true ' statement, it DOES catch an exception. What am I doing wrong ? Thanks, Ofer

  I have a Java application that creates a new thread to do some work. I can launch the new thread with no problems. When the "main" program terminates, I want the thread I created to keep running - which it does... But the problem is, when I run the main application from Eclipse or from Ant under Windows, control doesn't return unless the background process is killed. If I fork the main java process in ant, I want control to return to ant once the main thread is done with its work... But as it is, ant continues to wait until both the main process and the created thread are both terminated. How do I launch the thread in the background such that control will return to ant when the "main" application is finished? (By the way, when I run the same application under Linux, I am able to do this with no problems).
