  • Change present working directory of a calling shell from a ruby script

    - by Erik Kastman
    I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

  • ClearCase: Copy old versions with Snapshot Views under Windows

    - by cogmios
    Using IBM Rational ClearCase: - I have only access to Snapshot Views so NO dynamic Views I want to copy ALL versions from a certain changeset to c:\temp. I have already listed the changeset versions in a file (couple of hundred of versions, I only need the latest one), I do not have a baseline over this older set. What I now have and does not work: #!/usr/bin/perl -w # # PROGRAM: copytest.pl $filename = "Design test123.doc"; $view = "D:\\AdminViews\\ABC_R1_READ_2\\ABCD002\\ABC_DESIGN\\BLA Framework\\P0\\"; $version = "\\main\\ABC_R1_READ\\1"; $printhet = 'cleartool find . -name "' . $filename . '" -version version(' . $version. ') -exec "cmd /c copy %CLEARCASE_XPN% D:\temp\%CLEARCASE_PN%"'; system($printhet);

  • How to obtain position in file (byte-position) from java scanner?

    - by september2010
    How to obtain a position in file (byte-position) from the java scanner? Scanner scanner = new Scanner(new File("file")); scanner.useDelimiter("abc"); scanner.hasNext(); String result = scanner.next(); and now: how to get the position of result in file (in bytes)? Using scanner.match().start() is not the answer, because it gives the position within internal buffer.

  • Unlocking SVN working copy with unversioned resources

    - by Vijay Dev
    I have a repository which contains some unversioned directories and files. The server running svn was recently changed and since the checkout was done using the url svn://OLD-IP, I relocated my svn working copy, this time to the url svn://NEW-DOMAIN-NAME. Now since there are some unversioned resources, the switch did not happen properly and the working copy got locked. A cleanup operation did not work either because of these unversioned resources. I looked up in the net and found about svn ignore and tried that but to no use. I am unable to release all locks. Any ideas on solving the problem? Once I release the locks, I believe I can use svn ignore and carry on the relocate operation.

  • XAML Serialization object not using asp.net shadow copy

    - by mrwayne
    Hi, I'm having a problem where i use the XAML serializer / deserializer for a configuration type file that i have. The problem that i'm getting, is that the XAML serializer is returning objects from the assembly in the /Bin directory, while the rest of the web application is using assembly's stored in the ..../Temporary Files/.. directory. Is there any way to prevent this from happening? Is this a bug in the XAML serializer / assembly loading routines? Every time i compile i need to stop and start the asp.net application so the shadow copy and the bin are exactly the same file. Even when not making a change to the dll and recompiling still causes the problem. Any thoughts on how to get around this problem? Currently i've tried turning shadow copy off, but then i have the same problem of needing to shut down / start up the web app every time i compile. Help!

  • Assinging a GD reference to a new variable fails to copy

    - by Stomped
    This is a contrived example, but it illustrates my problem much more concisely then the code I'm using - and I've tested this and it exhibits the problem: $image = imagecreatefromjpeg('test.jpg'); $copy_of_image = $image; // The important bit imagedestroy($image); header('Content-type: image/jpeg'); imagejpeg($copy_of_image); Now, my expectation is that $copy_of_image is exactly that, but when I run this, it fails, printing out the URL of the script of all things. Comment out the imagedestroy() and it works just fine. a var_dump of $image provides: resource(3) of type (gd) So why can't I copy this? Apparently the assignment $copy_of_image = $image is creating a reference rather then a copy - is there a way to prevent that?

  • Copy hashtable to another hashtable using c++

    - by zengr
    I am starting with c++ and need to know, what should be the approach to copy one hashtable to another hashtable in C++? We can easily do this in java using: HashMap copyOfOriginal=new HashMap(original); But what about C++? How should I go about it? UPDATE Well, I am doing it at a very basic level,perhaps the java example was a wrong one to give. This is what I am trying to implement using C++: I have this hash array and each element of the array point to the head of a linked list. Which has it's individual nodes (data and next pointer). And now, I need to copy the complete hash array and the linked list each node is pointing to.

  • QObject cloning

    - by Olorin
    I know that Qobjects are supposed to be identities not values eg you cannot copy them and by default the copy constructor and asignment are disabled as explained in qt documentation. But is it possible to create a new Qobject from an existing one using a clone method? Would this be a logic error ? If i say QObject b; QObject a; b.cloneFrom(a); or QObject a = new QBject(); QObject b = new QBject(); b->cloneFrom(a); and the clone method copyes stuff like members etc would this be wrong? And if this is ok can i write my own copy constructor and asignment operator that does just that? Note: i actually want to try this with classes that inherit qobject.

  • Python: shutil.rmtree fails on Windows with 'Access is denied'

    - by Sridhar Ratnakumar
    In Python, when running shutil.rmtree over a folder that contains a read-only file, the following exception is printed: File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 221, in rmtree onerror(os.remove, fullname, sys.exc_info()) File "C:\Python26\lib\shutil.py", line 219, in rmtree os.remove(fullname) WindowsError: [Error 5] Access is denied: 'build\\tcl\\tcl8.5\\msgs\\af.msg' Looking in File Properties dialog I noticed that af.msg file is set to be read-only. So the question is: what is the simplest workaround/fix to get around this problem - given that my intention is to do an equivalent of rm -rf build/ but on Windows? (without having to use third-party tools like unxutils or cygwin - as this code is targeted to be run on a bare Windows install with Python 2.6 w/ PyWin32 installed)

  • Dynamically add files to visual studio deployment project.

    - by Graeme Yeo
    I've been desperately looking for the answer to this and I feel I'm missing something obvious. I need to copy a folder full of data files into the TARGETDIR of my deployment project at compile time. I can see how I would add individual files (ie. right click in File System and go to Add-File) but I have a folder full of data files which constantly get added to. I'd prefer not to have to add the new files each time I compile. I have tried using a PreBuildEvent to copy the files: copy $(ProjectDir)..\Data*.* $(TargetDir)Data\ which fails with error code 1 when I build. I can't help but feel I'm missing the point here though. Any suggestions? Thanks in advance. Graeme

  • Java - copy Jar Folder

    - by Ripei
    Hey Java - Developers Actually I am confronted with a Problem. I've got a ".apk-File" in one Package of my Application. apk is a kind of a jar File (apk = Android Package). I now want to copy this jar-file out of my Programm onto any other Location at the PC. Normally I would do this by using: FileInputStream is = new FileInputStream(this.getClass().getResource("/resources/myApp.apk").getFile()); And then write it on the disk with using a FileOutputStream. ... but since an .apk is a kind of a .jar it doesn't work. It just copies the .apk file. but without the containing other files. any help would be appreciated

  • Extract wav file from video file

    - by Nikos Steiakakis
    I am developing an application in which I need to extract the audio from a video. The audio needs to be extracted in .wav format but I do not have a problem with the video format. Any format will do, as long as I can extract the audio in a wav file. Currently I am using Windows Media Player COM control in a windows form to play the videos, but any other embedded player will do as well. Any suggestions on how to do this? Thanks

  • Locking behaviour is different via network shares

    - by MattH
    I have been trying to lock a file so that other cloned services cannot access the file. I then read the file, and then move the file when finished. The Move is allowed by using FileShare.Delete. However in later testing, we found that this approach does not work if we are looking at a network share. I appreciate my approach may not have been the best, but my specific question is: Why does the below demo work against the local file, but not against the network file? The more specific you can be the better, as I've found very little information in my searches that indicates network shares behave differently to local disks. string sourceFile = @"C:\TestFile.txt"; string localPath = @"C:\MyLocalFolder\TestFile.txt"; string networkPath = @"\\MyMachine\MyNetworkFolder\TestFile.txt"; File.WriteAllText(sourceFile, "Test data"); if (!File.Exists(localPath)) File.Copy(sourceFile, localPath); foreach (string path in new string[] { localPath, networkPath }) { using (FileStream fsLock = File.Open(path, FileMode.Open, FileAccess.ReadWrite, (FileShare.Read | FileShare.Delete))) { string target = path + ".out"; File.Move(path, target); //This is the point of failure, when working with networkPath if (File.Exists(target)) File.Delete(target); } if (!File.Exists(path)) File.Copy(sourceFile, path); }

  • shutil.rmtree fails on Windows with 'Access is denied'

  • How to merge a "branch" that isn't really a branch (wasn't created by an svn copy)

    - by MatrixFrog
    I'm working on a team with lots of people who are pretty unfamiliar with the concepts of version control systems, and are just kind of doing whatever seems to work, by trial and error. Someone created a "branch" from the trunk that is not ancestrally related to the trunk. My guess is it went something like this: They created a folder in branches. They checked out all the code from the trunk to somewhere on their desktop. They added all that code to the newly created folder as though it was a bunch of brand new files. So the repository isn't aware that all that code is actually just a copy of the trunk. When I look at the history of that branch in TortoiseSVN, and uncheck the "Stop on copy/rename" box, there is no revision that has the trunk (or any other path) under the "Copy from path" column. Then they made lots of changes on their "branch". Meanwhile, others were making lots of changes on the trunk. We tried to do a merge and of course it doesn't work. Because, the trunk and the fake branch are not ancestrally related. I can see only two ways to resolve this: Go through the logs on the "branch", look at every change that was made, and manually apply each change to the trunk. Go through the logs on the trunk, look at every change that was made between revision 540 (when the "branch" was created) and HEAD, and manually apply each change to the "branch". This involves 7 revisions one way or 11 revisions the other way, so neither one is really that terrible. But is there any way to cause the repository to "realize" that the branch really IS ancestrally related even though it was created incorrectly, so that we can take advantage of the built-in merging functionality in Eclipse/TortoiseSVN? (You may be wondering: Why did your company hire these people and allow them to access the SVN repository without making sure they knew how to use it properly first?! We didn't -- this is a school assignment, which is a collaboration between two different classes -- the ones in the lower class were given a very quick hand-wavey "overview" of SVN which didn't really teach them anything. I've asked everyone in the group to please PLEASE read the svn book, and I'll make sure we (the slightly more experienced half of the team) keep a close eye on the repository to ensure this doesn't happen again.)

  • Access 2007 & 2003 : Creating an mde for 2003 users with a 2007 dev copy issues

    - by Justin
    So i have an image on my computer that has office 2007, and I have the development copy of this database file where I corrected some code, added some fields, etc... I then converted the Access file (.mdb dev file) to Access 2002-2003 format to create an mde. So I then created the new mde, but when users try to open, it gives them the message that it is not the correct format and that they should upgrade to a newer version of access. So will i be able to get this done with having office 2007, and these other end users not having their new image pushed yet (so they still have office 2003)? I thought that if I converted the file to 2002-2003 then this should not be a problem Thanks Justin

    Hi, How to copy or duplicate gtk widgets? In my application I have one huge GtkComboBox created with one long for loop which eats up so much of time and I am using this combo at two places in one single screen. So, what I want to do is create this combo for one time and duplicate/copy it in another one so it will save my time. If I try to add same combo box pointer two times, gtk gives me error "child-paren != NULL" cause in gtk widget can have only single parent. So what to do? Thanks, PP.

Thanks in advance EDIT Let me explain in detail what I am looking for I want to copy file from windows to unix machine (correcting my previous question not from unix to windows) using ANT.

Before that as a check I tried to ftp unix sever from windows but it gave connection refused error(Do I need to provide my username and password,if that is the case what is the syntax). But I am able to connect through putty which asks for my user name and password. Does putty uses a different protocol. So if that is the case does ftp task works for me in ANT?. If not what task I need to use?

  • Mercurial: pull changes from unversioned copy

    - by Austin Hyde
    I am currently maintaining a Mercurial repository of the project I am working on. The rest of the team, however, doesn't. There is a "good" (unversioned) copy of the code base that I can access by SSH. What I would like to do is be able to do something like an hg pull from that good copy into my master repository whenever it gets updated. As far as I can tell, there's no obvious way to do this, as hg pull requires you have a source hg repository. I suppose I could use a utility like rsync to update my repository, then commit, but I was wondering: Is there was an easier/less contrived way to do this?
