1git-fast-export(1) 2================== 3 4NAME 5---- 6git-fast-export - Git data exporter 7 8 9SYNOPSIS 10-------- 11'git fast-export [options]' | 'git fast-import' 12 13DESCRIPTION 14----------- 15This program dumps the given revisions in a form suitable to be piped 16into 'git fast-import'. 17 18You can use it as a human-readable bundle replacement (see 19linkgit:git-bundle[1]), or as a kind of an interactive 20'git filter-branch'. 21 22 23OPTIONS 24------- 25--progress=<n>:: 26 Insert 'progress' statements every <n> objects, to be shown by 27 'git fast-import' during import. 28 29--signed-tags=(verbatim|warn|strip|abort):: 30 Specify how to handle signed tags. Since any transformation 31 after the export can change the tag names (which can also happen 32 when excluding revisions) the signatures will not match. 33+ 34When asking to 'abort' (which is the default), this program will die 35when encountering a signed tag. With 'strip', the tags will be made 36unsigned, with 'verbatim', they will be silently exported 37and with 'warn', they will be exported, but you will see a warning. 38 39--tag-of-filtered-object=(abort|drop|rewrite):: 40 Specify how to handle tags whose tagged object is filtered out. 41 Since revisions and files to export can be limited by path, 42 tagged objects may be filtered completely. 43+ 44When asking to 'abort' (which is the default), this program will die 45when encountering such a tag. With 'drop' it will omit such tags from 46the output. With 'rewrite', if the tagged object is a commit, it will 47rewrite the tag to tag an ancestor commit (via parent rewriting; see 48linkgit:git-rev-list[1]) 49 50-M:: 51-C:: 52 Perform move and/or copy detection, as described in the 53 linkgit:git-diff[1] manual page, and use it to generate 54 rename and copy commands in the output dump. 55+ 56Note that earlier versions of this command did not complain and 57produced incorrect results if you gave these options. 58 59--export-marks=<file>:: 60 Dumps the internal marks table to <file> when complete. 61 Marks are written one per line as `:markid SHA-1`. Only marks 62 for revisions are dumped; marks for blobs are ignored. 63 Backends can use this file to validate imports after they 64 have been completed, or to save the marks table across 65 incremental runs. As <file> is only opened and truncated 66 at completion, the same path can also be safely given to 67 \--import-marks. 68 69--import-marks=<file>:: 70 Before processing any input, load the marks specified in 71 <file>. The input file must exist, must be readable, and 72 must use the same format as produced by \--export-marks. 73+ 74Any commits that have already been marked will not be exported again. 75If the backend uses a similar \--import-marks file, this allows for 76incremental bidirectional exporting of the repository by keeping the 77marks the same across runs. 78 79--fake-missing-tagger:: 80 Some old repositories have tags without a tagger. The 81 fast-import protocol was pretty strict about that, and did not 82 allow that. So fake a tagger to be able to fast-import the 83 output. 84 85--no-data:: 86 Skip output of blob objects and instead refer to blobs via 87 their original SHA-1 hash. This is useful when rewriting the 88 directory structure or history of a repository without 89 touching the contents of individual files. Note that the 90 resulting stream can only be used by a repository which 91 already contains the necessary objects. 92 93--full-tree:: 94 This option will cause fast-export to issue a "deleteall" 95 directive for each commit followed by a full list of all files 96 in the commit (as opposed to just listing the files which are 97 different from the commit's first parent). 98 99[<git-rev-list-args>...]:: 100 A list of arguments, acceptable to 'git rev-parse' and 101 'git rev-list', that specifies the specific objects and references 102 to export. For example, `master{tilde}10..master` causes the 103 current master reference to be exported along with all objects 104 added since its 10th ancestor commit. 105 106EXAMPLES 107-------- 108 109------------------------------------------------------------------- 110$ git fast-export --all | (cd /empty/repository && git fast-import) 111------------------------------------------------------------------- 112 113This will export the whole repository and import it into the existing 114empty repository. Except for reencoding commits that are not in 115UTF-8, it would be a one-to-one mirror. 116 117----------------------------------------------------- 118$ git fast-export master~5..master | 119 sed "s|refs/heads/master|refs/heads/other|" | 120 git fast-import 121----------------------------------------------------- 122 123This makes a new branch called 'other' from 'master~5..master' 124(i.e. if 'master' has linear history, it will take the last 5 commits). 125 126Note that this assumes that none of the blobs and commit messages 127referenced by that revision range contains the string 128'refs/heads/master'. 129 130 131Limitations 132----------- 133 134Since 'git fast-import' cannot tag trees, you will not be 135able to export the linux-2.6.git repository completely, as it contains 136a tag referencing a tree instead of a commit. 137 138 139Author 140------ 141Written by Johannes E.
