filestream

I'm working with the filestream datatype for the first time (SQL Server 2008) and I'm running into issues when I am doing some fast insert/deletes. Basically the speed at which the files are actually removed from the FileSystem is way slower then the insert/delete speed even if I invoke the garbage collector manually (As far as I know the CHECKPOINT is supposed to invoke the garbage collector). The code below illustrate the problem - It takes roughly 30 seconds to executes, but you have to wait quite a few minutes for the last file to be deleted from the filesystem (When I look up the C:

In my project I have to create some temp files in an USB device, which I want to delete on Closing. So I used a code like this.fcommandHandler = new FileStream(TempFileName, FileMode.CreateNew, FileAccess.ReadWrite, FileShare.ReadWrite, 512, FileOptions.DeleteOnClose); It works fine. But the problem is I want to use one more FileOption, like No buffering. private const FileOptions FILE_FLAG_NO_BUFFERING = (FileOptions)0x20000000; this.fcommandHandler = new FileStream(TempFileName, FileMode.CreateNew, FileAccess.ReadWrite, FileShare.ReadWrite, 512, FileOptions.DeleteOnClose & FILE_FLAG_NO

I'm looking for guidance on how to find out which user has modified a particular file. While inotify is great to get notification when a particular file is touched, how do I figure out which user has modified that file? I can think of using lsof but I'm afraid that it may not be as "realtime" as I want and/or it might be too much of a tax on resources. By realtime, I mean that if a user simply executes a touch command on a file, by the time I run lsof on file, it may not be picked up by lsof . You can use audit deamon : sudo apt-get install auditd Choose a file to monitor touch /tmp/myfile Add

The following code is good for uploading text files, but it fails to upload JPEG files (not completely - the file name is good but the image is corrupted): private void up(string sourceFile, string targetFile) { try { string ftpServerIP = ConfigurationManager.AppSettings["ftpIP"]; string ftpUserID = ConfigurationManager.AppSettings["ftpUser"]; string ftpPassword = ConfigurationManager.AppSettings["ftpPass"]; //string ftpURI = ""; string filename = "ftp://" + ftpServerIP + "//" + targetFile; FtpWebRequest ftpReq = (FtpWebRequest)WebRequest.Create(filename); ftpReq.Method = WebRequestMethods.Ftp

After asking this question it is clear to me that I need to be able to perform the garbage collection in the fastest possible time. How is it possible to tell SQL Server filestream's garbage collector to delete all the files with high priority? I tried with the CHECKPOINT statement, even by setting a duration (CHECKPOINT 100), but nothing changes. After deleting 40000 filestream records I see that the garbage collector removes 4-5 files per second. How to tell him "delete them all now"? Unfortunately there's currently no way to force garbage collection (GC) of filestream data. It's handled by

This question already has answers here : How can I create directory tree in C++/Linux? (15 answers) I am now writing an extractor for a basic virtual file system archive (without compression). My extractor is running into problems when it writes a file to a directory that does not exist. Extract function : void extract(ifstream * ifs, unsigned int offset, unsigned int length, std::string path) { char * file = new char[length]; ifs->seekg(offset); ifs->read(file, length); ofstream ofs(path.c_str(), ios::out|ios::binary); ofs.write(file, length); ofs.close(); cout << patch << ", " << length <<
