  • PHP/Apache Deny folder access to user but not to script

    - by Piero
    Hey all, So I have this php web app, and one of my folder contains some files that can be downloaded. I have a download script that modifies the headers, in order to always offer a download link. (instead of showing a picture for example, when you click on a link, a download box pops out) Right now, if you enter a url like: http://www.mywebsite.com/content/ You get the listing of all the downloadable files, and of course, you can just download them all, without going through the website interface. Personally, I don't think it's a problem, since I often use downthemall or other downloading tool, and this type of access is a great time saver.... But of course my company does not think so :-p They want people to use the interface in order to view the Ads... Would they be a way, maybe with a protected .htaccess, to leave the folder access to my download script, but deny access to the users...? I hope I am making sense and you know what I mean :) All help/remarks appreciated!

  • PHP file_get_contents() behaves differently to browser.

    - by DaveG
    I'm trying to download the contents of a web page using PHP. When I issue the command: $f = file_get_contents("http://mobile.mybustracker.co.uk/mobile.php?searchMode=2"); It returns a page that reports that the server is down. Yet when I paste the same URL into my browser I get the expected page. Does anyone have any idea what's causing this? Does file_get_contents transmit any headers that differentiate it from a browser request?

  • unbuffered I/O in Linux

    - by stuck
    I'm writing lots and lots of data that will not be read again for weeks - as my program runs the amount of free memory on the machine (displayed with 'free' or 'top') drops very quickly, the amount of memory my app uses does not increase - neither does the amount of memory used by other processes. This leads me to believe the memory is being consumed by the filesystems cache - since I do not intend to read this data for a long time I'm hoping to bypass the systems buffers, such that my data is written directly to disk. I dont have dreams of improving perf or being a super ninja, my hope is to give a hint to the filesystem that I'm not going to be coming back for this memory any time soon, so dont spend time optimizing for those cases. On Windows I've faced similar problems and fixed the problem using FILE_FLAG_NO_BUFFERING|FILE_FLAG_WRITE_THROUGH - the machines memory was not consumed by my app and the machine was more usable in general. I'm hoping to duplicate the improvements I've seen but on Linux. On Windows there is the restriction of writing in sector sized pieces, I'm happy with this restriction for the amount of gain I've measured. is there a similar way to do this in Linux?

  • file_get_contents() removing tab and new line characters

    - by Patrick Murray
    I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

  • mapping file-* to a property

    - by andersonbd1
    Hi, I'd like to: <unjar src="lib/mst-service-impl*.zip" but I can't put an asterisk in there. It is only one file, but I don't want to hardcode the version in there. Is there a way to create a property with the asterisk (I know this particular example doesn't work, but perhaps something along these lines): <property name="my.jar" file="lib/mst-service-impl*.zip"> so that I could then do this: <unjar src="${my.jar}" Thanks, Ben

  • Proper permission and directoy location for Git Version Control

    - by CitadelCSAlum
    I am using Git Version Control on an remote server and I have set up a repository that multiple people will be using to push/fetch from. I have put the repo under /srv/subdir/git/.git I have been experiencing problem after problem it seems like. a) Is this location suitable for handling a project that will need to be accessed/modified by multiple developers and a designer? Or is there a better location? b)Do I need to modify the permissions on the subdir/ and git/ directories in order to allow remote access? If I do what is the appropriate permissions I should allow? I know this is a faily long request/question, but unfortunately like many other topics with well covered documentation, documentation does not always cover best practices. I would appreciate anybodies advice and suggestions? Thanks

  • What strategies are efficient to handle concurrent reads on heterogeneous multi-core architectures?

    - by fabrizioM
    I am tackling the challenge of using both the capabilities of a 8 core machine and a high-end GPU (Tesla 10). I have one big input file, one thread for each core, and one for the the GPU handling. The Gpu thread, to be efficient, needs a big number of lines from the input, while the Cpu thread needs only one line to proceed (storing multiple lines in a temp buffer was slower). The file doesn't need to be read sequentially. I am using boost. My strategy is to have a mutex on the input stream and each thread locks - unlocks it. This is not optimal because the gpu thread should have a higher precedence when locking the mutex, being the fastest and the most demanding one. I can come up with different solutions but before rush into implementation I would like to have some guidelines. What approach do you use / recommend ?
