temporary-files

Some time ago I wrote a question regarding the use of temporary files within a rails app. On thar particular case, I decided to use tempfile This causes a problem if I also want to use the x-sendfile directive ( as a parameter in Rails 2, or as a configuration option in Rails 3 ) so that the file sending is handled by my web server directly, not my rails app. So I thought about doing something like this: require 'tempfile' def foo() # creates a temporary file in tmp/ Tempfile.open('prefix', "#{Rails.root}/tmp") do |f| f.print('a temp message') f.flush send_file(f.path, :x_sendfile => true) #

How do you prevent ASP.NET from creating too many temporary files? My website creates gigabytes of temporary files, and that overflows the main partition on the server. How do I prevent this from happening? Setup a task in the task scheduler to clean up temporary files. I have no idea why this is not done by the OS (or by the creator of those files). Where are these temp files beeing generated? If it's in the "Temporary ASP.NET Files" folder, it's a result of your application beeing recompiled. Checkout MSDN for more information on dynamic compilation. One possible solution could be to

I get this warning saying that tmpnam is dangerous, but I would prefer to use it, since it can be used as is in Windows as well as Linux. I was wondering why it would be considered dangerous (I'm guessing it's because of the potential for misuse rather than it actually not working properly). Scharron From tmpnam manpage : The tmpnam() function generates a different string each time it is called, up to TMP_MAX times. If it is called more than TMP_MAX times, the behavior is implementation defined. Although tmpnam() generates names that are difficult to guess, it is nevertheless possible that

I know you can create a temporary file with tmpfile and than write to it, and close it when it is not needed anymore. But the problem I have is that I need the absolute path to the file like this: "/var/www/html/lolo/myfile.xml" Can I somehow get the path, even with some other function or trick? EDIT: I want to be able to download the file from the database, but without $fh = fopen("/var/www/html/myfile.xml", 'w') or die("no no"); fwrite($fh, $fileData); fclose($fh); because if I do it like this, there is a chance of overlapping, if more people try to download the same file at exactly the same

I want to use tempfile.NamedTemporaryFile() to write some contents into it and then open that file. I have written following code: tf = tempfile.NamedTemporaryFile() tfName = tf.name tf.seek(0) tf.write(contents) tf.flush() but I am unable to open this file and see its contents in notepad or similar application. Is there any way to achieve this? Why cant I do something like: os.system('start notepad.exe ' + tfName) at the end This could be one of two reasons: Firstly, by default the temporary file is deleted as soon as it is closed . To fix this use: tf = tempfile.NamedTemporaryFile(delete
