Simple AutoUpdating v2 - Update more efficiently

Hey guys, me again. I realized there were things I forgot to include in my first release here, so I recoded the whole system! Now with YAML integration, I added in the build feature in the version number. For example, major.minor.build. Without any further discussion here it is!

downloadFile(String site, String destination) - Download a file saved to a set directory.
site - URL to download from.
destination - Location to save the file to.

downloadFile(String site String destination

PHP:

public void downloadFile(String site, String destination)
{
        try {
                BufferedInputStream in = new BufferedInputStream(new URL(site).openStream());
                FileOutputStream fout = new FileOutputStream(destination);
 
                byte data[] = new byte[1024]; //Download 1 KB at a time
                int count;
                while((count = in.read(data, 0, 1024)) != -1)
                {
                        fout.write(data, 0, count);
                }
 
                in.close();
                fout.close();
        } catch(MalformedURLException e) {
                e.printStackTrace();
        } catch(IOException e) {
                e.printStackTrace();
        }
}

newTempFile(String site) - Download a files and uses it as a temporary file.
site - URL to download from.

newTempFile(String site) (open) newTempFile(String site) (close)

PHP:

public File newTempFile(String site)
{
        try {
                File file = File.createTempFile("latest", "");
                file.deleteOnExit();
 
                BufferedInputStream in = new BufferedInputStream(new URL(site).openStream());
                FileOutputStream fout = new FileOutputStream(file);
 
                byte data[] = new byte[1024]; //Download 1 KB at a time
                int count;
                while((count = in.read(data, 0, 1024)) != -1)
                {
                        fout.write(data, 0, count);
                }
 
                in.close();
                fout.close();
 
                return file;
        } catch(MalformedURLException e) {
                e.printStackTrace();
        } catch(IOException e) {
                e.printStackTrace();
        }
 
        return null;
}

Hmm looks nice. I'll try it later

 

nice

 

Nice!

 

As with your other thread, proper error handling is completely left out, which (like I said in the other post) could render plugins unusable due to simple things like I/O errors or connection issues, which shouldn't be the case. The Configuration will throw a FileNotFoundException if the connection to the .yml can't be established. The version number is rigid and doesn't allow for added sub-versions if need be.

I think it was mentioned also in your other post (or somewhere else) to simply download to the update-folder, which will make sure to auto-update upon server reload/restart, so you don't have to create unnecessary folders and temp files.

 

pfft This looks very similar to my code

 

Yeah, GREAT Tutorial
