  • OpToSoapDomComv.TRefCache.FNodes contains references to non-existing XMLNodes

    - by Bascy
    In our D2007 application we are using a Webservice, accessed with a THTTPRIO object. When the TDatamodule containing the THTTPRIO object is Destroyed an access violation occurs. This AV is raised when the TSoapDOMConvert is freed, which in turn executes: TRefCache(RefMap[0].Instance).Free calling destructor TRefCache.Destroy; begin FHREFs.Free; FMHREFs.Free; FNodes := nil; //Causes AV end; FNodes is a TInterfaceList containing one reference to IXMLNodes, but the object seems to have been freed before all this. Does anyone know this problem? How to solve it?

  • Storing objects in STL vector - minimal set of methods

    - by osgx
    Hello What is "minimal framework" (necessary methods) of object, which I will store in STL <vector>? For my assumptions: #include <vector> #include <cstring> using namespace std; class Doit { private: char *a; public: Doit(){a=(char*)malloc(10);} ~Doit(){free(a);} }; int main(){ vector<Doit> v(10); } gives *** glibc detected *** ./a.out: double free or corruption (fasttop): 0x0804b008 *** Aborted and in valgrind: malloc/free: 2 allocs, 12 frees, 50 bytes allocated.

  • Freeing a character pointer returns error

    - by Kraffs
    I'm trying to free a character pointer after having used it but it returns a strange error. The error says: "_CrtDbgREport: String too long or IO Error" The debugger itself returns no errors while compiling. The code currently looks like this: void RespondToUser(SOCKET client, SOCKET server) { char buffer[80]; char *temp = malloc(_scprintf("HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME)); sprintf(temp, "HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME); send(client, temp, strlen(temp), 0); closesocket(client); free(temp); ListenToUsers(server); } The problem only occurs when I try to free the temp pointer from the memory and not otherwise. What might be causing this?

  • IPC in C under linux

    - by poly
    I'm building a messaging solution with the followingsetup: all the messages are saved on a DB, two or more reader processes will read from this DB and send data to other process(es) which will send it over the network. My approach is depicted below, The following have 4 sender process with 4 fifos, and 2 readers with 2 fifos reader0 ? read data from DB reader1 ? read data from DB sending part network_handler0 ? network_handler_fifo0 ? reader0 network_handler1 ? network_handler_fifo1 ? reader1 network_handler2 ? network_handler_fifo2 ? reader0 network_handler3 ? network_handler_fifo3 ? reader1 receiving part network_handler0 ? reader_fifo0 ? reader0 ? write to DB network_handler1 ? reader_fifo1 ? reader1 ? write to DB network_handler2 ? reader_fifo0 ? reader0 ? write to DB network_handler3 ? reader_fifo1 ? reader1 ? write to DB I have few problem with this setup, and please note that the number of processes could be more than that based on the environment, so I could make it 20 readers and 10 network_handlers or it it could as shown above. The size of the buffer is 64K and the message size is 200k, is this small enough to make the write/read to/from fifo atomic? How can make the processes aware of each other, so for example, reader 0 writes to network_handler_fifo0 and network_handler_fifo2, how can I make it start writing on other fifo if the current ones are full or their network_handlers are dea d I thought about making the reader process writing more general in writing, so for example it writes to all network fifos using lock mechanism and stop writing on the one that its process dead, I didn't use it as lock mechanism could slow thing down. BTW, each network_handler is an SCTP association, so network_handler0 is association 0, network_handler1 is association 1 and so on. Any idea is appreciated. I mean even if I have to change the setup above.

  • Should I put a try-finally block after every Object.Create?

    - by max
    I have a general question about best practice in OO Delphi. Currently, I put try-finally blocks anywhere I create an object to free that object after usage (to avoid memory leaks). E.g.: aObject := TObject.Create; try aOBject.AProcedure(); ... finally aObject.Free; end; instead of: aObject := TObject.Create; aObject.AProcedure(); .. aObject.Free; Do you think it is good practice, or too much overhead? And what about the performance?

  • How can I add a character and enemies to a game that uses Parallax Scrolling? [on hold]

    - by Homer_Simpson
    I use the following code to create Parallax Scrolling: http://www.david-gouveia.com/portfolio/2d-camera-with-parallax-scrolling-in-xna/ Parallax Scrolling is working but I don't know how to add the player and the enemies. I tried to add a player class to the existing code, but if the player moves, then the camera isn't pointing at the player. The player leaves the camera viewport after a few seconds. I use the following code(as described in the tutorial), but it's not working: // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); What can I do so that the player is always the center of the camera? How should I add the character and the enemies to the game? Should I create a layer for the character and the enemies? For example: new Layer(_camera) { Parallax = new Vector2(0.9f, 1.0f) } At the moment, I don't use a layer for the player and I don't have implemented the enemies because I don't know how to do that. My player class: public class Player { Texture2D Playertex; public Vector2 Playerposition = new Vector2(400, 240); private Game1 game1; public Player(Game1 game) { game1 = game; } public void Load(ContentManager content) { Playertex = content.Load<Texture2D>("8bitmario"); TouchPanel.EnabledGestures = GestureType.HorizontalDrag; } public void Update(GameTime gameTime) { while (TouchPanel.IsGestureAvailable) { GestureSample gs = TouchPanel.ReadGesture(); switch (gs.GestureType) { case GestureType.HorizontalDrag: Playerposition.X += 3f; break; } } } public void Render(SpriteBatch batch) { batch.Draw(Playertex, new Vector2(Playerposition.X - Playertex.Width / 2, Playerposition.Y - Playertex.Height / 2), Color.White); } } In Game1, I update the player and camera class: protected override void Update(GameTime gameTime) { // Updates my character's position player.Update(gameTime); // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); foreach (Layer layer in _layers) layer.Draw(spriteBatch); spriteBatch.Begin(SpriteSortMode.Deferred, null, null, null, null, null, _camera.GetViewMatrix(new Vector2(0.0f, 0.0f))); player.Render(spriteBatch); spriteBatch.End(); base.Draw(gameTime); }

  • Allocate from buffer in C

    - by Grimless
    I am building a simple particle system and want to use a single array buffer of structs to manage my particles. That said, I can't find a C function that allows me to malloc() and free() from an arbitrary buffer. Here is some pseudocode to show my intent: Particle* particles = (Particle*) malloc( sizeof(Particle) * numParticles ); Particle* firstParticle = <buffer_alloc>( particles ); initialize_particle( firstParticle ); // ... Some more stuff if (firstParticle->life < 0) <buffer_free>( firstParticle ); // @ program's end free(particles); Where <buffer_alloc> and <buffer_free> are functions that allocate and free memory chunks from arbitrary pointers (possibly with additional metadata such as buffer length, etc.). Do such functions exist and/or is there a better way to do this? Thank you!

  • How to fork my android app?

    - by eidylon
    So I've written my first Android app, ... and want to be able to provide both free and paid versions. I wrote and compiled it in Eclipse on Windows. I'm wondering if it is possible, and how I would go about doing so, to have separate compile jobs somehow, so that I can maintain my free and paid versions from one set of source code, and just leave out certain bits for the paid version, but keep the main source the same. What are the recommended ways/best practices for devving a paid and free version of the same app from one set of source? Is it even possible?

  • How to run multiple instances of Tor?

    - by Ed
    I'm trying to set up a special proxy server (running Windows). It will have several instances of Privoxy and Tor running and my app will choose which Privoxy instance to send HTTP requests to depending on the load. Privoxy will then forward them to Tor. I'm using srvany.exe to create the services. At the moment I'm running 3 Privoxy and 3 Tor services (I copied the binaries to different folders). Each Privoxy service is listening to its own port (8118, 8119, 8120). I can see them listening in a port scanner. This is the application path (for srvany in registry) for the 1st service: C:\Anonymiser\Privoxy 01\privoxy.exe --service I've also configured the Tor services to listen to different ports (9050, 9052, 9054). This is the application path for the 1st service: C:\Anonymiser\Tor 01\tor.exe -f "C:\Anonymiser\Tor 01\torrc" The problem is, when I start the Tor services, only the first service I start is listening to its port. The others aren't listening. They listen if I run them separately. Any ideas what could be wrong? How can I make all 3 services listen on their assigned ports? This is one of my Privoxy configs: confdir . logdir . logfile privoxy.log debug 1 # show each GET/POST/CONNECT request debug 4096 # Startup banner and warnings debug 8192 # Errors - we highly recommended enabling this listen-address localhost:8118 toggle 0 enable-remote-toggle 0 enable-remote-http-toggle 0 enable-edit-actions 1 buffer-limit 4096 forwarded-connect-retries 0 forward-socks4a / localhost:9050 . This is one of my Tor configs: ControlPort 9051 Log notice stdout SocksListenAddress localhost SocksPort 9050 EDIT: Found a workaround. The Tor binary wants a lock on a file in the AppData folder. Because all of them want a lock on the same file, only the first one I start will be working. The workaround is to run each Tor instance under a different account. Not the best solution, but it works.

  • How to restrict file system when logged into terminal services

    - by pghcpa
    What I need to accomplish: With one login, when user is physically in the building I need them to see everything. When they are using terminal services with same login they should not be able to see the file system on the network. I can lock down the PC running terminal services as that is its only use. Details: Windows/2003 Server with terminal services. One login for a user (e.g., johndoe). When johndoe logs into the network at his desk in the office, he can see the network files according to group policy. When johndoe logs into terminal services from outside the building, we do not want to allow him see the network. Using 2x to do a published app, but that app has a "feature" that allows user to see network. Published application on termina services (only) is a document management system that is tied to windows login, so I can't give them two logins. With one login, when they are in the building I need them to see everything. When they are using terminal services they should not be able to see the network. I can lock down the PC running terminal services as that is its only use.

  • WebDAV through Apache2 permissions/missing files

    - by Strifariz
    I have a WebDAV setup on Apache2 on a server running Debian 5.0 (Lenny), which I am accessing through a mapped network drive under Windows 7. The setup appears to run fine, I receive no permission errors when copying a file to the share the first time, but the file never shows up in the directory (it's invisible, doing a ls -lha on the directory as root on the server also shows no files. When attempting to copy the file once more I am informed that the file already exists though, and I am asked if I wish to overwrite the file, when selecting "Yes" to this, I receive a permission error saying I'm not able to write to the folder. My logs aren't reporting any access violations of any kind, what could be the problem?

  • Flash plugin locks up Firefox, Chrome and Safari behind a corporate proxy, IE6 works fine

    - by Shevek
    At work I am forced by corporate policy to use IE6. Obviously this is not so good so I use FF for most of my browsing. However there is a problem once I have installed the Flash plug-in - FF locks up when trying to load Flash media. Looking at the status bar at the time of the lock up it appears this happens when the browser tries to get cross domain data. The Flash Active X plug-in in IE does not suffer this issue. I have tried it in a brand new profile in FF with Flash as the only plug in and it locks up. We have 2 different proxy servers and both exhibit the same problem. I have also tried Chrome and Safari and both lock up with the plug-in installed. So, has anyone else had this problem and solved it? Or, is there any way to disable cross domain data access in the flash plug-in? Or, is there any way to disable the "This site needs an additional plug-in" ribbon which appears when the plug-in is not installed. Many thanks!

  • Setting a time limit for a transaction in MySQL/InnoDB

    - by Trevor Burnham
    This sprang from this related question, where I wanted to know how to force two transactions to occur sequentially in a trivial case (where both are operating on only a single row). I got an answer—use SELECT ... FOR UPDATE as the first line of both transactions—but this leads to a problem: If the first transaction is never committed or rolled back, then the second transaction will be blocked indefinitely. The innodb_lock_wait_timeout variable sets the number of seconds after which the client trying to make the second transaction would be told "Sorry, try again"... but as far as I can tell, they'd be trying again until the next server reboot. So: Surely there must be a way to force a ROLLBACK if a transaction is taking forever? Must I resort to using a daemon to kill such transactions, and if so, what would such a daemon look like? If a connection is killed by wait_timeout or interactive_timeout mid-transaction, is the transaction rolled back? Is there a way to test this from the console? Clarification: innodb_lock_wait_timeout sets the number of seconds that a transaction will wait for a lock to be released before giving up; what I want is a way of forcing a lock to be released. Update: Here's a simple example that demonstrates why innodb_lock_wait_timeout is not sufficient to ensure that the second transaction is not blocked by the first: START TRANSACTION; SELECT SLEEP(55); COMMIT; With the default setting of innodb_lock_wait_timeout = 50, this transaction completes without errors after 55 seconds. And if you add an UPDATE before the SLEEP line, then initiate a second transaction from another client that tries to SELECT ... FOR UPDATE the same row, it's the second transaction that times out, not the one that fell asleep. What I'm looking for is a way to force an end to this transaction's restful slumber.

  • What is the most likely cause to a Blue Screen of Death when the user presses Ctrl-Alt-Delete?

    - by Jay
    My wife is experiencing this with her work laptop--she presses Ctrl-Alt-Delete to lock and she gets the BSOD. The first troubleshooting step is usually to "re-image", and it's locked down. So with this question, I am asking whether the behavior is unique enough that someone in the stack-universe knows exactly what this is (something I can tell her to tell her help desk support). Update: help desk said to order more RAM. Alt-tabbing caused the same behavior today. And...she learned that multiple users are affected. I'm not sure I'll be able to clean any additional info that will help w/ troubleshooting. I'll leave the question here for a bit and if an answer ends up being the actual solution, I'll accept it. If not, I think I should probably remove the question (i'll check meta). Update #2.5: The cause appears to be a ctrl-alt-delete keystroke while Sales Team Configurator is open. This can either be to lock the screen (there are workaround in answers already present) or to unlock the screen (no workaround for that).

  • Weird .#filename files on remote ssh-connected systems after mcedit

    - by etranger
    I'm using MacFusion sshfs in combination with Midnight Commander, and when I edit remote text files with mcedit, weird symlinks are created on the remote system. $ ls -l .* lrwxr-xr-x 1 user group 34 Jun 27 01:54 .#filename.txt -> [email protected] where etranger is my local login name, and mbp is a hostname of my notebook running MacOS. symlinks can be removed by running remote rm command, but cannot be deleted on the mac-fuse mounted volume and thus pollutes the filesystem. I cannot figure what part of software is responsible for this, and how I could fix this, any help is appreciated. EDIT: This appears to be mcedit behavior as documented here: https://dev.openwrt.org/ticket/8245 Apparently, sshfs fails to remove symlink to the lock file for some reason (".#" in filename, perhaps), and it pollutes the filesystem. A quick workaround is possible, using another bug of Midnight Commander: editing (F4) the broken symlink effectively converts it to a missing lock file it was supposed to point to, and removes the symlink itself. The newly created file may then be deleted normally. EDIT 2: Unchecking "Follow symlink" in MacFusion apparently allows sshfs to remove dead symlinks, so the problem disappears completely.
