   4 NAME
   5 ----
   6 svn-fe - convert an SVN "dumpfile" to a fast-import stream

   8 SYNOPSIS
   9 --------
  10 [verse]
  11 mkfifo backchannel &&
  12 svnadmin dump --deltas REPO |
  13         svn-fe [url] 3<backchannel |
  14         git fast-import --cat-blob-fd=3 3>backchannel

  16 DESCRIPTION
  17 -----------
  18
  19 Converts a Subversion dumpfile into input suitable for
  20 git-fast-import(1) and similar importers. REPO is a path to a
  21 Subversion repository mirrored on the local disk. Remote Subversion
  22 repositories can be mirrored on local disk using the `svnsync`
  23 command.
  24
  25 Note: this tool is very young.  The details of its commandline
  26 interface may change in backward incompatible ways.
  27
  28 INPUT FORMAT
  29 ------------
  30 Subversion's repository dump format is documented in full in
  31 `notes/dump-load-format.txt` from the Subversion source tree.
  32 Files in this format can be generated using the 'svnadmin dump' or
  33 'svk admin dump' command.
  34
  35 OUTPUT FORMAT
  36 -------------
  37 The fast-import format is documented by the git-fast-import(1)
  38 manual page.
  39
  40 NOTES
  41 -----
  42 Subversion dumps do not record a separate author and committer for
  43 each revision, nor do they record a separate display name and email
  44 address for each author.  Like git-svn(1), 'svn-fe' will use the name
  45
  46 ---------
  47 user <user@UUID>
  48 ---------
  49
  50 as committer, where 'user' is the value of the `svn:author` property
  51 and 'UUID' the repository's identifier.
  52
  53 To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
  54 the end of each commit log message if passed a URL on the command
  55 line.  This line has the form `git-svn-id: URL@REVNO UUID`.
  56
  57 The resulting repository will generally require further processing
  58 to put each project in its own repository and to separate the history
  59 of each branch.  The 'git filter-repo --subdirectory-filter' command
  60 may be useful for this purpose.
  61
  62 BUGS
  63 ----
  64 Empty directories and unknown properties are silently discarded.
  65
  66 The exit status does not reflect whether an error was detected.
