David Barr	3b8a305173	vcs-svn: drop no-op reset methods Since v1.7.5~42^2~6 (vcs-svn: remove buffer_read_string) buffer_reset() does nothing thus fast_export_reset() also. Signed-off-by: David Barr <davidbarr@google.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>	13 years ago
Jonathan Nieder	fbdd4f6fb4	vcs-svn: cap number of bytes read from sliding view Introduce a "max_off" field in struct sliding_view, roughly representing a maximum number of bytes that can be read from "file". If it is set to a nonnegative integer, a call to move_window() attempting to put the right endpoint beyond that offset will return an error instead. The idea is to use this when applying Subversion-format deltas to prevent reads past the end of the preimage (which has known length). Without such a check, corrupt deltas would cause svn-fe to block indefinitely when data in the input pipe is exhausted.

Jonathan Nieder	b747e5675d	test-svn-fe: split off "test-svn-fe -d" into a separate function The helper for testing the svndiff library is getting dangerously close to the right margin. Split it off into a separate function so it is easier to contemplate on its own. In the process, make the test_svnfe_usage[] string static so it can be shared by the two functions (and other future functions in this test program) without fuss. In other words, this just unindents the code a little. No functional change intended. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>	14 years ago
Jonathan Nieder	ddcc8c5b46	vcs-svn: skeleton of an svn delta parser A delta in the subversion delta (svndiff0) format consists of the magic bytes SVN\0 followed by a sequence of windows of a certain well specified format (starting with five integers). Add an svndiff0_apply function and test-svn-fe -d commandline tool to parse such a delta in the special case of not including any windows. Later patches will add features to turn this into a fully functional delta applier for svn-fe to use to parse the streams produced by "svnrdump dump" and "svnadmin dump --deltas". The content of symlinks starts with the word "link " in Subversion's worldview, so we need to be able to prepend that text to input for the sake of delta application. So initialization of the input state of the delta preimage is left to the calling program, giving callers a chance to seed the buffer with text of their choice.

Jonathan Nieder	5c28a8b054	vcs-svn: Check for errors from open() test-svn-fe segfaults when passed a bogus path. Simplify debugging by exiting with a meaningful error message instead. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago
David Barr	21746aa34f	SVN dump parser svndump parses data that is in SVN dumpfile format produced by `svnadmin dump` with the help of line_buffer and uses repo_tree and fast_export to emit a git fast-import stream. Based roughly on com.hydrografix.svndump 0.92 from the SvnToCCase project at <http://svn2cc.sarovar.org/>, by Stefan Hegny and others.
