From 512536a54a1a211a9f582e76cbf12850dc7d5466 Mon Sep 17 00:00:00 2001 From: Doug Zongker Date: Wed, 17 Feb 2010 16:11:44 -0800 Subject: relocate applypatch; add type system and new functions to edify - Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5 --- applypatch/utils.h | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 applypatch/utils.h (limited to 'applypatch/utils.h') diff --git a/applypatch/utils.h b/applypatch/utils.h new file mode 100644 index 0000000..d6d6f1d --- /dev/null +++ b/applypatch/utils.h @@ -0,0 +1,30 @@ +/* + * Copyright (C) 2009 The Android Open Source Project + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +#ifndef _BUILD_TOOLS_APPLYPATCH_UTILS_H +#define _BUILD_TOOLS_APPLYPATCH_UTILS_H + +#include + +// Read and write little-endian values of various sizes. + +void Write4(int value, FILE* f); +void Write8(long long value, FILE* f); +int Read2(unsigned char* p); +int Read4(unsigned char* p); +long long Read8(unsigned char* p); + +#endif // _BUILD_TOOLS_APPLYPATCH_UTILS_H -- cgit v1.1
