  • SVN hook script conflict

    - by user297303
    I am trying to write a pre-commit hook script that will alter a specific svn-property of a folder/file. The script looks fairly similar to the one that is documented in the svn book. I figured out how to set/change the property of a node and when executing the binding function svn.fs.commit_txn the property of the node actually gets set. But at the moment tortoise always gives me a conflict on the folder I am altering the property. I wrote my script with Python but am new python and hook scripts. Hope someone can give me a clue why I am getting this conflict..

  • drupal - using variable_set, hook block and hook menu to save config values then print out in custom

    - by bert
    I am trying to 1) implement the hook menu and variable_set in the block hook and to solicit and store configuration values from user, 2) then use retrieve configuration values and 3) pass them out into a template using theme hook when page is shown. However I need a bit of a push on step two and three! // ===================== file: my_module.php function my_module_block($op = 'list', $delta = 0, $edit = array()) { switch($op) { case 'list': $blocks[0] = array( 'info' => t('Find Something'), // required value - this shows up in your list of blocks 'region' => 'left', // default region on the page 'weight' => 0, // position the block vertically within its column.

  • Suppress task switch keys (winkey, alt-tab, alt-esc, ctrl-esc) using low-level keyboard hook

    - by matt
    I'm trying to suppress task switch keys (such as winkey, alt-tab, alt-esc, ctrl-esc, etc.) by using a low-level keyboard hook. I'm using the following LowLevelKeyboardProc callback: IntPtr HookCallback(int nCode, IntPtr wParam, ref KBDLLHOOKSTRUCT lParam) { if (nCode >= 0) { bool suppress = false; // Suppress left and right windows keys. if (lParam.Key == VK_LWIN || lParam.Key == VK_RWIN) suppress = true; // Suppress alt-tab. if (lParam.Key == VK_TAB && HasAltModifier(lParam.Flags)) suppress = true; // Suppress alt-escape. if (lParam.Key == VK_ESCAPE && HasAltModifier(lParam.Flags)) suppress = true; // Suppress ctrl-escape. /* How do I hook CTRL-ESCAPE ? */ // Suppress keys by returning 1. if (suppress) return new IntPtr(1); } return CallNextHookEx(HookID, nCode, wParam, ref lParam); } bool HasAltModifier(int flags) { return (flags & 0x20) == 0x20; } However, I'm at a loss as to how to suppress the CTRL-ESC combination. Any suggestions? Thanks.

  • Keyboard hook return different symbols from card reader depends whther my app in focus or not

    - by user363868
    I code WinForm application where one of the input is magnetic stripe card reader (CR). I am using code George Mamaladze's article Processing Global Mouse and Keyboard Hooks in C# on codeproject.com to listen keyboard (USB card reader acts same way as keyboard) and I have weird situation. One card reader CR1 (Unitech MS240-2UG) produces keystroke which I intercept on KeyPress event analyze that I intercept certain patter like %ABCD-6EFJHI? and trigger some logic. Analysis required because user can type something else into application or in another application meanwhile my app is open When I use another card reader CR2 (IdTech IDBM-334133) keystroke intercepted by hook started from number 5 instead of % (It is actually same key on keyboard). Since it is starting sentinel it is very important for me to have ability recognize input from card reader. Moreover if my app running in background and I have focus on Notepad when I swipe card string %ABCD-6EFJHI? appears in Notepad and same way, with proper starting character) intercepted by keyboard hook. If swiped when focus on Form it is 5ABCD-6EFJHI? User who tried app with another card reader has same result as me with CR2. Only CR1 works for me as expected I was looking into Device manager of Windows and both devices use same HID driver supplied by MS. I checked devices though respective software from CR makers and starting and ending sentinels set to % and ? respective on both. I would appreciate and ideas and thoughts as I hit the wall myself Thank you

  • Closing a hook that captures global input events

    - by Margus
    Intro Here is an example to illustrate the problem. Consider I am tracking and displaying mouse global current position and last click button and position to the user. Here is an image: To archive capturing click events on windows box, that would and will be sent to the other programs event messaging queue, I create a hook using winapi namely user32.dll library. This is outside JDK sandbox, so I use JNA to call the native library. This all works perfectly, but it does not close as I expect it to. My question is - How do I properly close following example program?

  • Using SVN post-commit hook to update only files that have been commited

    - by fondie
    I am using an SVN repository for my web development work. I have a development site set up which holds a checkout of the repository. I have set up an SVN post-commit hook so that whenever a commit is made to the repository the development site is updated: cd /home/www/dev_ssl /usr/bin/svn up This works fine but due to the size of the repository the updates take a long time (approx. 3 minutes) which is rather frustrating when making regular commits. What I'd like is to change the post-commit hook to only update those files/directories that have been committed but I don't know how to go about doing this. Updating the "lowest common directory" would probably be the best solution, e.g. If committing the follow files: /branches/feature_x/images/logo.jpg /branches/feature_x/css/screen.css It would update the directory: /branches/feature_x/ Can anyone help me create a solution that achieves this please? Thanks! Update: The repository and development site are located on the same server so network issues shouldn't be involved. CPU usage is very low, and I/O should be ok (it's running on hi-spec dedicated server) The development site is approx. 7.5GB in size and contains approx. 600,000 items, this is mainly due to having multiple branches/tags

  • pre-commit hook in svn: could not be translated from the native locale to UTF-8

    - by Alexandre Moraes
    Hi everybody, I have a problem with my pre-commit hook. This hook test if a file is locked when the user commits. When a bad condition happens, it should output that the another user is locking this file or if nobody is locking, it should show "you are not locking this file message (file´s name)". The error happens when the file´s name has some latin character like "ç" and tortoise show me this in the output. Commit failed (details follow): Commit blocked by pre-commit hook (exit code 1) with output: [Erro output could not be translated from the native locale to UTF-8.] Do you know how can I solve this?

  • Git pre-commit hook: getting list of changed files

    - by Mikko Ohtamaa
    I am developing validation and linting utility to be integrated with various commit hooks, including Git one https://github.com/miohtama/vvv Currently validators and linters are run against the whole project codebase on every commit. However, it would be much more optimal to run them against changed files only. For this, I would need to know changed files list in my Git precommit hook (in Python) https://github.com/miohtama/vvv/blob/master/vvv/hooks/git.py What options I have to extract the changed files list (in Python if that matters)?

  • In a pre-commit hook - how to access/compare current and previous versions of files

    - by EthanML
    I'm trying to add to our existing pre-commit SVN hook so that it will check for and block an increase in file size for files in specific directory/s. I've written a python script to compare two file sizes, which takes two files as arguments and uses sys.exit(0) or (1) to return the result, this part seems to work fine. My problem is in calling the python script from the batch file, how to reference the newly committed and previous versions of each file? The existing code is new to me and a mess of %REPOS%, %TXN%s etc and I'm not sure how to go about using them. Is there a simple, standard way of doing this? It also already contains code to loop through the changed files using svnlook changed, so that part shouldn't be an issue. Thanks very much

  • C++ hook process and show status

    - by David
    Ok so I am learning C++ slowly. I am familiar with all the console syntax and everything, but now I'm moving on to windows programming. Now what im trying to do, is create a DLL that I inject into a process, so it's hooked in. All I want the C++ application to do, is have text in it, that says "Hooked" if it's successfully injected, and an error if something wrong happened. Or even if I can do it without a DLL, Just open an executable, and when the certain process I'm trying to hook is opened, the status is changed to "Hooked". Also I have a safaribooksonline.com account so if there is any good reads you would recommend, just write it down. thanks

  • Pre Commit Hook for JSLint in Mercurial and Git

    - by jrburke
    I want to run JSLint before a commit into either a Mercurial or Git repo is done. I want this as an automatic step that is set up instead of relying on the developer (mainly me) remembering to run JSLint before-hand. I normally run JSLint while developing, but want to specify a contract on JS files that they pass JSLint before being committed to the repo. For Mercurial, this page spells out the precommit syntax, but the only variables that seem to be available are the parent1 and parent2 changeset IDs involved in the commit. What I really want are a list of file names that are involved with the commit, so that I can then choose the .js file and run jslint over them. Similar issue for GIT, the default info available as part of the precommit script seems limited. What might work is calling hg status/git status as part of the precommit script, parse that output to find JS files then do the work that way. I was hoping for something easier though, and I am not sure if calling status as part of a precommit hook reflect the correct information. For instance in Git if the changes files have not been added yet, but the git commit uses -a, would the files show up in the correct section of the git status output as being part of the commit set? Update: I got something working, it is visible here: http://github.com/jrburke/dvcs_jslint/

  • Port Win32 DLL hook to Linux

    - by peachykeen
    I have a program (NWShader) which hooks into a second program's OpenGL calls (NWN) to do post-processing effects and whatnot. NWShader was originally built for Windows, generally modern versions (win32), and uses both DLL exports (to get Windows to load it and grab some OpenGL functions) and Detours (to hook into other functions). I'm using the trick where Win will look in the current directory for any DLLs before checking the sysdir, so it loads mine. I have on DLL that redirects with this method: #pragma comment(linker, "/export:oldFunc=nwshader.newFunc) To send them to a different named function in my own DLL. I then do any processing and call the original function from the system DLL. I need to port NWShader to Linux (NWN exists in both flavors). As far as I can tell, what I need to make is a shared library (.so file). If this is preloaded before the NWN executable (I found a shell script to handle this), my functions will be called. The only problem is I need to call the original function (I would use various DLL dynamic loading methods for this, I think) and need to be able to do Detour-like hooking of internal functions. At the moment I'm building on Ubuntu 9.10 x64 (with the 32-bit compiler flags). I haven't been able to find much on Google to help with this, but I don't know exactly what the *nix community refers to it as. I can code C++, but I'm more used to Windows. Being OpenGL, the only part the needs modified to be compatible with Linux is the hooking code and the calls. Is there a simple and easy way to do this, or will it involve recreating Detours and dynamically loading the original function addresses?

  • Problem with Keyboard hook proc

    - by Steve
    The background: My form has a TWebBrowser. I want to close the form with ESC but the TWebBrowser eats the keystrokes - so I decided to go with a keyboard hook. The problem is that the Form can be open in multiple instances at the same time. No matter what I do, in some situations, if there are two instances open of my form, closing one of them closes the other as well. I've attached some sample code. Any ideas on what causes the issue? var EmailDetailsForm: TEmailDetailsForm; KeyboardHook: HHook; implementation function KeyboardHookProc(Code: Integer; wParam, lParam: LongInt): LongInt; stdcall; var hWnd: THandle; I: Integer; F: TForm; begin if Code < 0 then Result := CallNextHookEx(KeyboardHook, Code, wParam, lParam) else begin case wParam of VK_ESCAPE: if (lParam and $80000000) <> $00000000 then begin hWnd := GetForegroundWindow; for I := 0 to Screen.FormCount - 1 do begin F := Screen.Forms[I]; if F.Handle = hWnd then if F is TEmailDetailsForm then begin PostMessage(hWnd, WM_CLOSE, 0, 0); Result := HC_SKIP; break; end; end; //for end; //if else Result := CallNextHookEx(KeyboardHook, Code, wParam, lParam); end; //case end; //if end; function TEmailDetailsForm.CheckInstance: Boolean; var I, J: Integer; F: TForm; begin Result := false; J := 0; for I := 0 to Screen.FormCount - 1 do begin F := Screen.Forms[I]; if F is TEmailDetailsForm then begin J := J + 1; if J = 2 then begin Result := true; break; end; end; end; end; procedure TEmailDetailsForm.FormCreate(Sender: TObject); begin if not CheckInstance then KeyboardHook := SetWindowsHookEx(WH_KEYBOARD, @KeyboardHookProc, 0, GetCurrentThreadId()); end; procedure TEmailDetailsForm.FormDestroy(Sender: TObject); begin if not CheckInstance then UnHookWindowsHookEx(KeyboardHook); end;

  • java: useful example of a shutdown hook?

    - by Jason S
    I'm trying to make sure my Java application takes reasonable steps to be robust, and part of that involves shutting down gracefully. I am reading about shutdown hooks and I don't actually get how to make use of them in practice. Is there a practical example out there? Let's say I had a really simple application like this one below, which writes numbers to a file, 10 to a line, in batches of 100, and I want to make sure a given batch finishes if the program is interrupted. I get how to register a shutdown hook but I have no idea how to integrate that into my application. Any suggestions? package com.example.test.concurrency; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.PrintWriter; public class GracefulShutdownTest1 { final private int N; final private File f; public GracefulShutdownTest1(File f, int N) { this.f=f; this.N = N; } public void run() { PrintWriter pw = null; try { FileOutputStream fos = new FileOutputStream(this.f); pw = new PrintWriter(fos); for (int i = 0; i < N; ++i) writeBatch(pw, i); } catch (FileNotFoundException e) { e.printStackTrace(); } finally { pw.close(); } } private void writeBatch(PrintWriter pw, int i) { for (int j = 0; j < 100; ++j) { int k = i*100+j; pw.write(Integer.toString(k)); if ((j+1)%10 == 0) pw.write('\n'); else pw.write(' '); } } static public void main(String[] args) { if (args.length < 2) { System.out.println("args = [file] [N] " +"where file = output filename, N=batch count"); } else { new GracefulShutdownTest1( new File(args[0]), Integer.parseInt(args[1]) ).run(); } } }

  • AnkhSVN client side pre-commit hook

    - by santa
    Basically I want to do the same thing as the fella over there. It seems that everybody was thinking about server-side hooks (with all their evil potential). I want a client side script be run before commit so astyle can format the code the way my boss likes to see it. Since my IDE (VS2010Pro) automatically checks when a file changed on the disk an opts me in for reloading it, there is no real evil with all that. Is there any (clean) way to accomplish that with AnkhSVN? Maybe there's also a way to extend VisualStudio to call my pre-commit-script...

  • Hook perm for more than one content type

    - by Andrew
    Drupal 6.x I have this module that manages four different content types. For that matter, how do I define permission for each content within the same module? Is that even possible? I can't figure out how to define permission for each content type cuz hook_perm has to be named with module name and it doesn't have any argument(like hook_access $node) to return permission base on content type. Any help would be highly appreciated.

  • Hook key & key combinations from keyboard with Qt 4.6

    - by Viet
    Let's say I have a window-less application which has only an icon on the Taskbar (Windows, Mac OS X & Linux). I want it to capture some key & key combinations, let's say Right Control + Right Shift. Upon keying in correct, combination, it will do something, say take screenshot. I can do window-less app, icon on the Taskbar and screen capture but I don't know how to monitor keyboard globally for key combinations. Please kindly advise. Any help or hint is greatly appreciated! Thanks in advance!

  • Detect a tag in hook-script SVN

    - by Mark
    Is there a way that I can detect a tag/branch in SVN? Could I find out where the commits destination is? I want to check that all externals are set to a specific version of the folder they are pointing to, I don't want to prevent commits to a tag with this script. I am writing the script with the c-pyhton bindings.
