As such, there are no guarantees about the stability of the API. The author reserves the right to arbitrarily break the API for any reason.** - -This repository hosts a collection of compression related libraries. The goal of this project is to provide pure Go implementations for popular compression algorithms beyond what the Go standard library provides. The goals for these packages are as follows: -* Maintainable: That the code remains well documented, well tested, readable, easy to maintain, and easy to verify that it conforms to the specification for the format being implemented. -* Performant: To be able to compress and decompress within at least 80% of the rates that the C implementations are able to achieve. -* Flexible: That the code provides low-level and fine granularity control over the compression streams similar to what the C APIs would provide. - -Of these three, the first objective is often at odds with the other two objectives and provides interesting challenges. Higher performance can often be achieved by muddling abstraction layers or using non-intuitive low-level primitives. Also, more features and functionality, while useful in some situations, often complicates the API. Thus, this package will attempt to satisfy all the goals, but will defer to favoring maintainability when the performance or flexibility benefits are not significant enough. - - -## Library Status ## - -For the packages available, only some features are currently implemented: - -| Package | Reader | Writer | -| ------- | :----: | :----: | -| brotli | :white_check_mark: | | -| bzip2 | :white_check_mark: | :white_check_mark: | -| flate | :white_check_mark: | | -| xflate | :white_check_mark: | :white_check_mark: | - -This library is in active development.

It is powered by the Go standard library and several third-party, pure-Go libraries. - -Files are put into the root of the archive; directories are recursively added, preserving structure. - -- Make whole archives from a list of files -- Open whole archives to a folder -- Extract specific files/folders from archives -- Stream files in and out of archives without needing actual files on disk -- Traverse archive contents without loading them -- Compress files -- Decompress files -- Streaming compression and decompression -- Several archive and compression formats supported - -### Format-dependent features - -- Optionally create a top-level folder to avoid littering a directory or archive root with files -- Toggle overwrite existing files -- Adjust compression level -- Zip: store (not compress) already-compressed files -- Make all necessary directories -- Open password-protected RAR archives -- Optionally continue with other files after an error - -### Supported archive formats - -- .zip -- .tar -- .tar.gz or .tgz -- .tar.bz2 or .tbz2 -- .tar.xz or .txz -- .tar.lz4 or .tlz4 -- .tar.sz or .tsz -- .rar (open only) - -### Supported compression formats - -- bzip2 -- gzip -- lz4 -- snappy (sz) -- xz - - -## Install - -```bash -go get -u github.com/mholt/archiver/cmd/arc -``` - -Or download binaries from the [releases](https://github.com/mholt/archiver/releases) page. - - -## Command Use - -### Make new archive - -```bash -# Syntax: arc archive [archive name] [input files...] - -$ arc archive test.tar.gz file1.txt images/file2.jpg folder/subfolder -``` - -(At least one input file is required.) - -### Extract entire archive - -```bash -# Syntax: arc unarchive [archive name] [destination] - -$ arc unarchive test.tar.gz -``` - -(The destination path is optional; default is current directory.) - -The archive name must end with a supported file extension—this is how it knows what kind of archive to make. Run `arc help` for more help. - -### List archive contents - -```bash -# Syntax: arc ls [archive name] - -$ arc ls caddy_dist.tar.gz -drwxr-xr-x matt staff 0 2018-09-19 15:47:18 -0600 MDT dist/ --rw-r--r-- matt staff 6148 2017-08-07 18:34:22 -0600 MDT dist/.DS_Store --rw-r--r-- matt staff 22481 2018-09-19 15:47:18 -0600 MDT dist/CHANGES.txt --rw-r--r-- matt staff 17189 2018-09-19 15:47:18 -0600 MDT dist/EULA.txt --rw-r--r-- matt staff 25261 2016-03-07 16:32:00 -0700 MST dist/LICENSES.txt --rw-r--r-- matt staff 1017 2018-09-19 15:47:18 -0600 MDT dist/README.txt --rw-r--r-- matt staff 288 2016-03-21 11:52:38 -0600 MDT dist/gitcookie.sh.enc -... -``` - -### Extract a specific file or folder from an archive - -```bash -# Syntax: arc extract [archive name] [path in archive] [destination on disk] - -$ arc extract test.tar.gz foo/hello.txt extracted/hello.txt -``` - -### Compress a single file - -```bash -# Syntax: arc compress [input file] [output file] - -$ arc compress test.txt compressed_test.txt.gz -$ arc compress test.txt gz -``` - -For convenience, the output file (second argument) may simply be a compression format (without leading dot), in which case the output filename will be the same as the input filename but with the format extension appended, and the input file will be deleted if successful. - -### Decompress a single file - -```bash -# Syntax: arc decompress [input file] [output file] - -$ arc decompress test.txt.gz original_test.txt -$ arc decompress test.txt.gz -``` - -For convenience, the output file (second argument) may be omitted. In that case, the output filename will have the same name as the input filename, but with the compression extension stripped from the end; and the input file will be deleted if successful. - -### Flags - -Flags are specified before the subcommand. Use `arc help` or `arc -h` to get usage help and a description of flags with their default values. - -## Library Use - -The archiver package allows you to easily create and open archives, walk their contents, extract specific files, compress and decompress files, and even stream archives in and out using pure io.Reader and io.Writer interfaces, without ever needing to touch the disk. - -```go -import "github.com/mholt/archiver" -``` - -[See the package's GoDoc](https://godoc.org/github.com/mholt/archiver) for full API documentation. - -For example, creating or unpacking an archive file: - -```go -err := archiver.Archive([]string{"testdata", "other/file.txt"}, "test.zip") -// ... -err = archiver.Unarchive("test.tar.gz", "test") -``` - -The archive format is determined by file extension. (There are [several functions in this package](https://godoc.org/github.com/mholt/archiver) which perform a task by inferring the format from file extension or file header, including `Archive()`, `Unarchive()`, `CompressFile()`, and `DecompressFile()`.) - -To configure the archiver used or perform, create an instance of the format's type: - -```go -z := archiver.Zip{ - CompressionLevel: flate.DefaultCompression, - MkdirAll: true, - SelectiveCompression: true, - ContinueOnError: false, - OverwriteExisting: false, - ImplicitTopLevelFolder: false, -} - -err := z.Archive([]string{"testdata", "other/file.txt"}, "/Users/matt/Desktop/test.zip") -``` - -Inspecting an archive: - -```go -err = z.Walk("/Users/matt/Desktop/test.zip", func(f archiver.File) error { - zfh, ok := f.Header.(zip.FileHeader) - if ok { - fmt.Println("Filename:", zfh.Name) - } - return nil -}) -``` - -Streaming files into an archive that is being written to the HTTP response: - -```go -err = z.Create(responseWriter) -if err != nil { - return err -} -defer z.Close() - -for _, fname := range filenames { - info, err := os.Stat(fname) - if err != nil { - return err - } - - // get file's name for the inside of the archive - internalName, err := archiver.NameInArchive(info, fname, fname) - if err != nil { - return err - } - - // open the file - file, err := os.Open(f) - if err != nil { - return err - } - - // write it to the archive - err = z.Write(archiver.File{ - FileInfo: archiver.FileInfo{ - FileInfo: info, - CustomName: internalName, - }, - ReadCloser: file, - }) - file.Close() - if err != nil { - return err - } -} -``` - -The `archiver.File` type allows you to use actual files with archives, or to mimic files when you only have streams. - -There's a lot more that can be done, too. [See the GoDoc](https://godoc.org/github.com/mholt/archiver) for full API documentation. - -**Security note: This package does NOT attempt to mitigate zip-slip attacks.** It is [extremely difficult](https://github.com/rubyzip/rubyzip/pull/376) [to do properly](https://github.com/mholt/archiver/pull/65#issuecomment-395988244) and [seemingly impossible to mitigate effectively across platforms](https://github.com/golang/go/issues/20126). [Attempted fixes have broken processing of legitimate files in production](https://github.com/mholt/archiver/pull/70#issuecomment-423267320), rendering the program unusable. Our recommendation instead is to inspect the contents of an untrusted archive before extracting it (this package provides `Walkers`) and decide if you want to proceed with extraction. - - -## Project Values - -This project has a few principle-based goals that guide its development: - -- **Do our thing really well.** Our thing is creating, opening, inspecting, compressing, and streaming archive files. It is not meant to be a replacement for specific archive format tools like tar, zip, etc. that have lots of features and customizability. (Some customizability is OK, but not to the extent that it becomes overly complicated or error-prone.) - -- **Have good tests.** Changes should be covered by tests. - -- **Limit dependencies.** Keep the package lightweight. - -- **Pure Go.** This means no cgo or other external/system dependencies. This package should be able to stand on its own and cross-compile easily to any platform -- and that includes its library dependencies. - -- **Idiomatic Go.** Keep interfaces small, variable names semantic, vet shows no errors, the linter is generally quiet, etc. - -- **Be elegant.** This package should be elegant to use and its code should be elegant when reading and testing. If it doesn't feel good, fix it up. - -- **Well-documented.** Use comments prudently; explain why non-obvious code is necessary (and use tests to enforce it). Keep the docs updated, and have examples where helpful. - -- **Keep it efficient.** This often means keep it simple. Fast code is valuable. - -- **Consensus.** Contributions should ideally be approved by multiple reviewers before being merged. Generally, avoid merging multi-chunk changes that do not go through at least one or two iterations/reviews. Except for trivial changes, PRs are seldom ready to merge right away. - -- **Have fun contributing.** Coding is awesome! - -We welcome contributions and appreciate your efforts! However, please open issues to discuss any changes before spending the time preparing a pull request. This will save time, reduce frustration, and help coordinate the work.

This makes the -compressor even faster. We have now a large time budget to beat the -compression ratio of the xz tool. For enwik8 we have now over 40 seconds -to reduce the compressed file size for another 7 MiB. - -### 2016-01-30 - -I simplified the encoder. Speed and compression rate increased -dramatically. A high compression rate affects also the decompression -speed. The approach with the buffer and optimizing for operation -compression rate has not been successful. Going for the maximum length -appears to be the best approach. - -### 2016-01-28 - -The release v0.4 is ready. It provides a working xz implementation, -which is rather slow, but works and is interoperable with the xz tool. -It is an important milestone. - -### 2016-01-10 - -I have the first working implementation of an xz reader and writer. I'm -happy about reaching this milestone. - -### 2015-12-02 - -I'm now ready to implement xz because, I have a working LZMA2 -implementation. I decided today that v0.4 will use the slow encoder -using the operations buffer to be able to go back, if I intend to do so. - -### 2015-10-21 - -I have restarted the work on the library. While trying to implement -LZMA2, I discovered that I need to resimplify the encoder and decoder -functions. The option approach is too complicated. Using a limited byte -writer and not caring for written bytes at all and not to try to handle -uncompressed data simplifies the LZMA encoder and decoder much. -Processing uncompressed data and handling limits is a feature of the -LZMA2 format not of LZMA. - -I learned an interesting method from the LZO format. If the last copy is -too far away they are moving the head one 2 bytes and not 1 byte to -reduce processing times. - -### 2015-08-26 - -I have now reimplemented the lzma package.

It -seems to work now quite nicely. - -### 2015-06-05 - -The overflow issue was interesting to research, however Henry S. Warren -Jr. Hacker's Delight book was very helpful as usual and had the issue -explained perfectly. Fefe's information on his website was based on the -C FAQ and quite bad, because it didn't address the issue of -MININT == -MININT. - -### 2015-06-04 - -It has been a productive day. I improved the interface of lzma. Reader -and lzma. Writer and fixed the error handling. - -### 2015-06-01 - -By computing the bit length of the LZMA operations I was able to -improve the greedy algorithm implementation. By using an 8 MByte buffer -the compression rate was not as good as for xz but already better then -gzip default. - -Compression is currently slow, but this is something we will be able to -improve over time. - -### 2015-05-26 - -Checked the license of ogier/pflag. The binary lzmago binary should -include the license terms for the pflag library. - -I added the endorsement clause as used by Google for the Go sources the -LICENSE file. - -### 2015-05-22 - -The package lzb contains now the basic implementation for creating or -reading LZMA byte streams. It allows the support for the implementation -of the DAG-shortest-path algorithm for the compression function. - -### 2015-04-23 - -Completed yesterday the lzbase classes. I'm a little bit concerned that -using the components may require too much code, but on the other hand -there is a lot of flexibility. - -### 2015-04-22 - -Implemented Reader and Writer during the Bayern game against Porto. The -second half gave me enough time. - -### 2015-04-21 - -While showering today morning I discovered that the design for OpEncoder -and OpDecoder doesn't work, because encoding/decoding might depend on -the current status of the dictionary. This is not exactly the right way -to start the day. - -Therefore we need to keep the Reader and Writer design. This time around -we simplify it by ignoring size limits. These can be added by wrappers -around the Reader and Writer interfaces. The Parameters type isn't -needed anymore. - -However I will implement a ReaderState and WriterState type to use -static typing to ensure the right State object is combined with the -right lzbase. Reader and lzbase. Writer. - -As a start I have implemented ReaderState and WriterState to ensure -that the state for reading is only used by readers and WriterState only -used by Writers. - -### 2015-04-20 - -Today I implemented the OpDecoder and tested OpEncoder and OpDecoder. - -### 2015-04-08 - -Came up with a new simplified design for lzbase. I implemented already -the type State that replaces OpCodec. - -### 2015-04-06 - -The new lzma package is now fully usable and lzmago is using it now. The -old lzma package has been completely removed. - -### 2015-04-05 - -Implemented lzma. Reader and tested it. - -### 2015-04-04 - -Implemented baseReader by adapting code form lzma. Reader. - -### 2015-04-03 - -The opCodec has been copied yesterday to lzma2. opCodec has a high -number of dependencies on other files in lzma2. Therefore I had to copy -almost all files from lzma. - -### 2015-03-31 - -Removed only a TODO item. - -However in Francesco Campoy's presentation "Go for Javaneros -(Javaïstes?)" is the the idea that using an embedded field E, all the -methods of E will be defined on T. If E is an interface T satisfies E. - - - -I have never used this, but it seems to be a cool idea. - -### 2015-03-30 - -Finished the type writerDict and wrote a simple test. - -### 2015-03-25 - -I started to implement the writerDict. - -### 2015-03-24 - -After thinking long about the LZMA2 code and several false starts, I -have now a plan to create a self-sufficient lzma2 package that supports -the classic LZMA format as well as LZMA2. The core idea is to support a -baseReader and baseWriter type that support the basic LZMA stream -without any headers. Both types must support the reuse of dictionaries -and the opCodec. - -### 2015-01-10 - -1. Implemented simple lzmago tool -2. Tested tool against large 4.4G file - * compression worked correctly; tested decompression with lzma - * decompression hits a full buffer condition -3. Fixed a bug in the compressor and wrote a test for it -4.
