MCL-2913Slow internet connection can prevent Minecraft downloading
If you have a slow Internet connection, the launcher may fail to download completely the files.
14w32b file is sized about 700 kB in my computer but the real size is about 7.3 MB
Console log:

Explanations:
I successfully decompile launcher.jar and I found this:
protected HttpURLConnection makeConnection(URL url) throws IOException { HttpURLConnection connection = (HttpURLConnection)url.openConnection(this.proxy); connection.setUseCaches(false); connection.setDefaultUseCaches(false); connection.setRequestProperty("Cache-Control", "no-store,max-age=0,no-cache"); connection.setRequestProperty("Expires", "0"); connection.setRequestProperty("Pragma", "no-cache"); connection.setConnectTimeout(5000); //High timeout connections may prevent downloading files connection.setReadTimeout(30000); //This causes the connection to abort after 30 sec return connection; }
So if the file can't be downloaded within 30 seconds, the file is partial and prevent Minecraft to run.
Then Minecraft 1.7.10 can't be downloaded in connections under 171 kB/s or 1369 kb/s.
How to reproduce: (not reliable)
Download lots of big files.
Possible fixes:
- Give unlimited time to download files.
- Use a quite large timeout (like 3 min).
Environment
Windows 8.1, Java 1.8.
Slow Internet connection.
