I'm checking out FPC JVM branch, however, in the middle of the process, it fails with "Decompression of svndiff data failed". The error keeps occuring, so I guess it's not a connection problem or something unpredictable. I'm using latest TortoiseSVN by the way, which is compiled for SVN 1.7.

This occurs for me too.
I just repeat the procedure to it work again.

According to http://subversion.open.collab.net/ds/viewMessage.do?dsForumId=4&dsMessageId=322466 , this error may be caused by an error in the zlib library shipped with Windows Vista. Are you using Vista?

Some people report success with manually reducing their MTU: http://subversion.open.collab.net/ds/viewMessage.do?dsForumId=4&dsMessageId=335721 . This may be related to the fact that FPC svn server sits behind a broken (ISP) router that drops all ICMP packets (including those required for proper TCP functioning, such as the ones used for indicating that a packet needs to be fragmented because it's too big).

I've run "svnadmin verify" on the fpc repository on the server, but it didn't report any errors. It would have been strange if it had, since otherwise other people should have encountered the same problem (in a way that would not be solvable by simply restarting or continuing the checkout process afterwards).

The problem might still be related to the MTU. Maybe a patch since then has exactly the "right" size to trigger the problem. Try lowering it a bit to see what happens.

Are you connected via CABLE or WIRELESS. We have similar errors connecting to our svn repositories via LTE because of a buggy proxy server in between.

Hell yeah, I follow the suggestion in the thread to lower it down from 1500 to 1300 and it works! Thanks Jonas.

Just a small hint: for read only use, svn2.freepascal.org is a much better server: much faster than svn.freepascal.org and no MTU trouble. Even trees I plan to commit from I typically checkout from svn2 and then relocate the checkout. svn2 might seldomly get out of sync, but we typically notice and fix this within a few hours.
