commit 4b752015b5208a96c2d1b6c1c6b8589884b8b2b6 from: Stefan Sperling date: Thu Jun 30 21:35:28 2022 UTC switch 'tog diff' and 'tog blame' to Myers diff for speed Make the choice of diff algorithm configurable by diff API users. The got and gotweb programs keep using Patience diffs which are prettier than Myers. But tog should be as fast as possible since it is being used interactively. If performance of Patience diff gets improved later we can consider switching tog back over to it. ok tracey jamsek commit - 0dca135e7628142c56b3f71c3b5eb875f4fe6c7f commit + 4b752015b5208a96c2d1b6c1c6b8589884b8b2b6 blob - d9c4a8353c2a3778cc4d66443ac60c9d35daa07b blob + 5f7f00007937a048564e685aac0a8c6b9e98adab --- got/got.c +++ got/got.c @@ -3584,7 +3584,8 @@ diff_blobs(struct got_object_id *blob_id1, struct got_ while (path[0] == '/') path++; err = got_diff_blob(NULL, NULL, blob1, blob2, f1, f2, path, path, - diff_context, ignore_whitespace, force_text_diff, outfile); + GOT_DIFF_ALGORITHM_PATIENCE, diff_context, ignore_whitespace, + force_text_diff, outfile); done: if (fd1 != -1 && close(fd1) == -1 && err == NULL) err = got_error_from_errno("close"); @@ -3645,6 +3646,7 @@ diff_trees(struct got_object_id *tree_id1, struct got_ arg.diff_context = diff_context; arg.ignore_whitespace = ignore_whitespace; arg.force_text_diff = force_text_diff; + arg.diff_algo = GOT_DIFF_ALGORITHM_PATIENCE; arg.outfile = outfile; arg.line_offsets = NULL; arg.nlines = 0; @@ -4590,6 +4592,7 @@ struct print_diff_arg { const char *id_str; int header_shown; int diff_staged; + enum got_diff_algorithm diff_algo; int ignore_whitespace; int force_text_diff; FILE *f1; @@ -4720,8 +4723,8 @@ print_diff(void *arg, unsigned char status, unsigned c } err = got_diff_objects_as_blobs(NULL, NULL, a->f1, a->f2, fd1, fd2, blob_id, staged_blob_id, label1, label2, - a->diff_context, a->ignore_whitespace, a->force_text_diff, - a->repo, stdout); + a->diff_algo, a->diff_context, a->ignore_whitespace, + a->force_text_diff, a->repo, stdout); goto done; } @@ -4812,8 +4815,8 @@ print_diff(void *arg, unsigned char status, unsigned c } err = got_diff_blob_file(blob1, a->f1, size1, label1, f2 ?
