a C\C++ library and command-line tools for Diff & Patch between binary files or directories(folder); cross-platform; runs fast; create small delta/differential; support large files and limit memory requires when diff & patch.
HDiffPatch defines its own patch file format, this lib is also compatible with the bsdiff4 patch format and partially compatible with the open-vcdiff and xdelta3 patch file format VCDIFF(RFC 3284).
if need patch (OTA) on embedded systems,MCU,NB-IoT..., see demo HPatchLite (+ tinyuz), can run on 1KB RAM devices!
update your own Android Apk? Jar or Zip file diff & patch? try ApkDiffPatch, to create smaller delta/differential! NOTE: ApkDiffPath can't be used by Android app store, because it requires re-signing apks before diff.
sfpatcher not require re-signing apks (like archive-patcher), is designed for Android app store, patch speed up by a factor of xx than archive-patcher & run with O(1) memory.
if you not have the old versions(too many or not obtain or have been modified), thus cannot create the delta in advance. you can see demo hsynz (like zsync), the new version is only need released once and the owners of the old version get the information about the new version and do the diff&patch themselves. hsynz support zstd compressor & run faster than zsync.
NOTE: This library does not deal with file metadata, such as file last wirte time, permissions, link file, etc... To this library, a file is just as a stream of bytes; You can extend this library or use other tools.
Download from latest release : Command line app for Windows, Linux, MacOS; and .so patch lib for Android.
( release files build by projects in path HDiffPatch/builds
)
use cmdline to create a delta:
$hdiffz -m-6 -SD -c-zstd-21-24 -d oldPath newPath outDiffFile
if file'size is very large, try changing -m-6
to -s-64
apply the delta:
$hpatchz oldPath diffFile outNewPath
$ cd <dir>/HDiffPatch
Try:
$ make LZMA=0 ZSTD=0 MD5=0
bzip2 : if the build fails with fatal error: bzlib.h: No such file or directory
, use your system's package manager to install the libbz2 package and try again. install bzip2: $ apt-get install libbz2
or $ sudo apt-get install libbz2-dev
or $ yum -y install bzip2
or $ brew install bzip2
...
Alternatively, get the optional library headers (+bzip2 library) and build completely: $ git clone https://github.com/sisong/bzip2.git ../bzip2 && pushd ../bzip2 && make && sudo make install && popd
if need lzma zstd md5 support, Try:
$ git clone https://github.com/sisong/libmd5.git ../libmd5
$ git clone https://github.com/sisong/lzma.git ../lzma
$ git clone https://github.com/sisong/zstd.git ../zstd
$ make
Tip: You can use $ make -j
to compile in parallel.
Before you build builds/vc/HDiffPatch.sln
by Visual Studio
, first get the libraries into sibling folders, like so:
$ git clone https://github.com/sisong/libmd5.git ../libmd5
$ git clone https://github.com/sisong/lzma.git ../lzma
$ git clone https://github.com/sisong/zstd.git ../zstd
$ git clone https://github.com/sisong/zlib.git ../zlib
$ git clone https://github.com/sisong/bzip2.git ../bzip2
- install Android NDK
$ cd <dir>/HDiffPatch/builds/android_ndk_jni_mk
$ build_libs.sh
(or$ build_libs.bat
on windows, then got *.so files)- import file
com/github/sisong/HPatch.java
(fromHDiffPatch/builds/android_ndk_jni_mk/java/
) & .so files, java code can call the patch function in libhpatchz.so
