Maybe your site have a redirect from http to https or something. In that case, use https link in the patcher.

Give me your link in DM and I'll have a look.

Edit: @GoldCash Your patchlist.txt is wrong, you have to remove the D:/Client/ from every line.

Also when I first opened the link, it said website unavailable for like 5 second then Chrome refreshed. I'm sure there are some protection / pre-filter enabled in your webserver. I never used LiteSpeed so can't tell more.

Are u using a free storage just for test? Cuz this will not work  I tried with a lot of free cloud storage, but nothing worked. I bought a cloud storage for 1year (cost me 12€) and it worked instantly.

Sry for my bad english.

Hi, try to change crc hash to md5, it helped me.

In Common.cs

Add this in begging of the file:

using System.Security.Cryptography;

and after:

        public static string GetHash(string Name)
        {
            if (Name == string.Empty)
                return string.Empty;

            CRC crc = new CRC();

            string Hash = string.Empty;

            using (FileStream fileStream = File.Open(Name, FileMode.Open))
            {
                foreach (byte b in crc.ComputeHash(fileStream))
                {
                    Hash += b.ToString("x2").ToLower();
                }
            }

            return Hash;
        }

add:

        public static string CalculateMD5Hash(string Name)
        {
            if (Name == string.Empty)
                return null;

            MD5 md5 = System.Security.Cryptography.MD5.Create();

            string Hash = string.Empty;

            try
            {
                using (FileStream fileStream = File.Open(Name, FileMode.Open, FileAccess.Read, FileShare.Read))
                {
                    foreach (byte b in md5.ComputeHash(fileStream))
                    {
                        Hash += b.ToString("x2").ToLower();
                    }
                }
            }
            catch
            {
                MessageBox.Show("Can't open: " + Name);
            }

            return Hash;
        }

In FileChecker.cs find:

if (!File.Exists(file.Name) || Common.GetHash(file.Name) != file.Hash)

and replace with:

if (!File.Exists(file.Name) || Common.CalculateMD5Hash(file.Name) != file.Hash)

After these changes you'll have MD5 Patcher

PS: Atm I'm experiencing some problems with progress bar, will add solution if I'll find it.

 

 

 

 

Also I'd like to share php script which generate patchlist.txt (probably will be useful for someone):

  Hide contents

 

<?php
/*
Usage: Upload this file to the web-server, in folder with patchlist.txt and open it in browser.
Note: I recommend to protect this file from public usage with password (put file in folder, change output file and directory path and and use .htaccess)
*/
function list_directory($dir) {
	$file_list = array();
	$stack[] = $dir;

	while ($stack) {
		$current_dir = array_pop($stack);
		if ($dh = opendir($current_dir)) {
			while (($file = readdir($dh)) !== false) {
				if ($file !== '.' AND $file !== '..') {
					$current_file = "{$current_dir}/{$file}";
					$report = array();
					if (is_file($current_file)) {
						$file_list[] = "{$current_dir}/{$file}";
					} elseif (is_dir($current_file)) {
						$stack[] = $current_file;
						$file_list[] = "{$current_dir}/{$file}/";
					}
				}
			}
		}
	}

	return $file_list;
}

$files = list_directory('.'); // Path to directory with files
sort($files, SORT_NATURAL | SORT_FLAG_CASE);
$line = "";
foreach($files as $file)
{
	$hash = hash_file( 'crc32b', $file );
	$size = filesize($file);

	if($hash == "00000000" || preg_match("/patchlist/", $file))
		continue;

	$file_n = preg_replace("/^../","",$file);
	echo $file_n . " " . $hash . " " . $size . "<br>";
	$line .= $file_n . " " . $hash . " " . $size . "\r\n";
}

$handle = fopen("patchlist.txt", "w+"); // Path to output file
fwrite($handle, $line);
fclose($handle);
?>

 

Best Regards

Hi, I've done as indicated.
After creating the patch list and using the patcher, everything downloads perfectly.

If I close the patcher and open it up again, somehow it checks for the files and then redownloads all the files...

anyone knows how to fix this?

the patcher is working but the problem is, that he downloading everytime all files, not only the changed files.

@ TMP4 you had some temporary keys. What are the passwords? i cannot create new cause your design is fixed with this key.
