From 252712111fad127db365e3dd764309fe5658679a Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 13 Oct 2010 04:21:43 -0500 Subject: vcs-svn: parse svndiff0 window header Each window in a subversion delta (svndiff0-format file) starts with a window header, consisting of five integers with variable-length representation: source view offset source view length output length instructions length auxiliary data length Parse it. The result is not usable for deltas with nonempty postimage yet; in fact, this only adds support for deltas without any instructions or auxiliary data. This is a good place to stop, though, since that little support lets us add some simple passing tests concerning error handling to the test suite.
