Please see [here](https://github.com/s3git/s3git/blob/master/README.md) for a general introduction to s3git including its use cases. 7 | 8 | This module is based on the [s3git-go](https://github.com/s3git/s3git-go) package that is invoked via foreign function interface (FFI). 9 | 10 | **DISCLAIMER: This software is still under development (although the storage format/model is stable) -- use at your own peril for now** 11 | 12 | **Note that the API is not stable yet, you can expect minor changes/extensions** 13 | 14 | Installation 15 | ------------ 16 | 17 | Please make sure you have a working Golang environment installed, otherwise you cannot build the shared library. See [install golang](https://github.com/minio/minio/blob/master/INSTALLGO.md) for setting up a working Golang environment. 18 | 19 | Also the [s3git-go](https://github.com/s3git/s3git-go) package needs to be available locally (`go get -d github.com/s3git/s3git-go`). 20 | 21 | ```sh 22 | $ go build -buildmode=c-shared -o s3git-py.so 23 | ``` 24 | 25 | Examples 26 | -------- 27 | 28 | Here are some common examples of typical tasks. 29 | 30 | Create a repository 31 | ------------------- 32 | 33 | ``` 34 | $ python3 35 | >>> import s3git 36 | >>> repo = s3git.init_repository('.') 37 | >>> repo.add('hello s3git') 38 | >>> repo.commit('My first s3git commit from Python') 39 | >>> exit() 40 | $ s3git log --pretty 41 | 113b9e900588fd830deed131c0f2f2cdd88b4751286ecc4967d0d4990aff6821c2426425955ec104797b142e93204a604e4ba420b3b617724237476128333de8 My first s3git commit from Python 42 | $ s3git ls 43 | c518dc5f1d95258dc91f6d285e7ea7300f37dea4dd517173f2e23afe0cb52bc9d8eb18683cdcf377e96a2d5a81585e61f6d27fa5d017cad53836bd050e9f105f 44 | $ s3git cat c518dc5f1d95258dc91f6d285e7ea7300f37dea4dd517173f2e23afe0cb52bc9d8eb18683cdcf377e96a2d5a81585e61f6d27fa5d017cad53836bd050e9f105f 45 | hello s3git 46 | ``` 47 | 48 | Clone a repository 49 | ------------------ 50 | 51 | ```py 52 | >>> import s3git 53 | >>> repo = s3git.clone('s3://s3git-spoon-knife', '.', access='AKIAJYNT4FCBFWDQPERQ', secret='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') 54 | >>> for l in repo.list(''): 55 | >>> print(l) 56 | ``` 57 | 58 | Dump contents of a repository 59 | ----------------------------- 60 | 61 | ```py 62 | >>> import s3git 63 | >>> repo = s3git.init_repository('.') 64 | >>> repo.add('hello s3git') 65 | >>> repo.add('Python rocks') 66 | >>> repo.add(open('local-file.txt', 'rb')) 67 | >>> for l in repo.list(''): 68 | >>> repo.get(l).read() 69 | ``` 70 | 71 | List multiple commits 72 | --------------------- 73 | 74 | ```py 75 | >>> import s3git 76 | >>> repo = s3git.init_repository('.') 77 | >>> repo.add('string 1') 78 | >>> repo.commit('first commit') 79 | >>> repo.add('string 2') 80 | >>> repo.commit('second commit') 81 | >>> for c in repo.list_commits(): 82 | >>> print(c['Message']) 83 | ``` 84 | 85 | Push to a remote repository 86 | --------------------------- 87 | 88 | ```py 89 | >>> import s3git 90 | >>> repo = s3git.init_repository('.') 91 | >>> repo.add('just some stuff') 92 | >>> repo.add('more stuff') 93 | >>> repo.add('and yet more stuff') 94 | >>> repo.commit('initial commit') 95 | >>> repo.remote_add('primary', 's3://s3git-spoon-knife', access='AKIAJYNT4FCBFWDQPERQ', secret='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') 96 | >>> repo.push() 97 | ``` 98 | 99 | Create a snapshot 100 | ----------------- 101 | 102 | ```py 103 | >>> import s3git 104 | >>> repo = s3git.init_repository('.') 105 | >>> repo.snapshot_create("Initial snapshot") 106 | >>> repo.snapshot_list("") 107 | ``` 108 | 109 | Limitations and Optimizations 110 | ----------------------------- 111 | 112 | - Streams are not yet natively supported (temp files are used under the hood) 113 | - Methods that return arrays (eg. list or list_commits) are currently limited to a maximum of 1000 responses 114 | - Proper error handling is largely missing 115 | 116 | Contributions 117 | ------------- 118 | 119 | Contributions are welcome, please submit a pull request for any enhancements. 120 | 121 | License 122 | ------- 123 | 124 | s3git-rb is released under the Apache License v2.0.
