From e605164d1da51087882a468bcf3f5d36d3a9d4ba Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Thu, 15 Jul 2010 18:25:39 +0200 Subject: [PATCH] Add a sample user for the svndump library The svn-fe tool takes a Subversion dump file as input and produces a fast-import stream as output. This can be useful as a low-level tool in building other importers, or for debugging the vcs-svn library. make svn-fe make svn-fe.1 to test.

REPO is a path to a +Subversion repository mirrored on the local disk. Remote Subversion +repositories can be mirrored on local disk using the `svnsync` +command. + +INPUT FORMAT +------------ +Subversion's repository dump format is documented in full in +`notes/dump-load-format.txt` from the Subversion source tree. +Files in this format can be generated using the 'svnadmin dump' or +'svk admin dump' command. + +OUTPUT FORMAT +------------- +The fast-import format is documented by the git-fast-import(1) +manual page. + +NOTES +----- +Subversion dumps do not record a separate author and committer for +each revision, nor a separate display name and email address for +each author. Like git-svn(1), 'svn-fe' will use the name + +--------- +user +--------- + +as committer, where 'user' is the value of the `svn:author` property +and 'UUID' the repository's identifier. + +To support incremental imports, 'svn-fe' will put a `git-svn-id` +line at the end of each commit log message if passed an url on the +command line. This line has the form `git-svn-id: URL@REVNO UUID`. + +Empty directories and unknown properties are silently discarded. + +The resulting repository will generally require further processing +to put each project in its own repository and to separate the history +of each branch. The 'git filter-branch --subdirectory-filter' command +may be useful for this purpose. + +BUGS +---- +Litters the current working directory with .bin files for +persistence. Will be fixed when the svn-fe infrastructure is aware of +a Git working directory. + +SEE ALSO +-------- +git-svn(1), svn2git(1), svk(1), git-filter-branch(1), git-fast-import(1), +https://svn.apache.org/repos/asf/subversion/trunk/notes/dump-load-format.txt -- 2.30.2
