Hi - I'm trying to create a minimal-case example creating a delta between two strings and applying that delta to a svn repository in C. I'm able to add and delete files and add content to an empty file, but so far I haven't been able to take the contents of a file, diff them with a string, and use that diff to update the file in the repository.
Two immediate questions: 1) are the md5 checksums integral to the process of creating a delta - i.e., can it be ignored or is calculating md5 checksums a required step? 2) is there an example somewhere of this process being done in C code as a minimal example? Something along the lines of "given a repository and two strings str1 and str2, here's how to apply the difference to a file in a repository?" A code snippet appears below to better illustrate what I'm trying to do - I can expand it if that would help any. Thanks, CY svn_repos_get_commit_editor4(editor, &edit_baton, repos, NULL, full_path, base, user, logmsg, NULL, NULL, NULL, NULL, pool); (*editor)->open_root(edit_baton, youngest_rev, pool, &root_baton); (*editor)->open_file(bu_vls_addr(&filepath), root_baton, youngest_rev, pool, &file_baton); char *testcontents = "test contents 2"; teststring = svn_string_createf(pool, "%s", testcontents2); svn_stream_t *newstream = svn_stream_from_string(teststring, pool); (*editor)->apply_textdelta(file_baton, NULL, pool, &handler, &handler_baton); svn_txdelta_run(oldstream, newstream, handler, handler_baton, svn_checksum_md5, &local_checksum, NULL, NULL, pool, pool); (*editor)->close_file(file_baton, NULL, pool); (*editor)->close_edit(edit_baton, pool);
