-DESCRIPTION ------------ - -Converts a Subversion dumpfile into input suitable for -git-fast-import(1) and similar importers. 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. - -Note: this tool is very young. The details of its commandline -interface may change in backward incompatible ways. - -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 do they record a separate display name and email -address for each author. Like git-svn(1), 'svn-fe' will use the name - ---------- -user <user@UUID> ---------- - -as committer, where 'user' is the value of the `svn:author` property -and 'UUID' the repository's identifier. - -To support incremental imports, 'svn-fe' puts a `git-svn-id` line at -the end of each commit log message if passed a URL on the command -line. This line has the form `git-svn-id: URL@REVNO UUID`. - -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-repo --subdirectory-filter' command -may be useful for this purpose. - -BUGS ----- -Empty directories and unknown properties are silently discarded. - -The exit status does not reflect whether an error was detected. - -SEE ALSO --------- -git-svn(1), svn2git(1), svk(1), git-filter-repo(1), git-fast-import(1), -https://svn.apache.org/repos/asf/subversion/trunk/notes/dump-load-format.txt diff --git a/contrib/svn-fe/svnrdump_sim.py b/contrib/svn-fe/svnrdump_sim.py deleted file mode 100755 index 8a3cee6175..0000000000 --- a/contrib/svn-fe/svnrdump_sim.py +++ /dev/null @@ -1,68 +0,0 @@ -#!/usr/bin/env python -""" -Simulates svnrdump by replaying an existing dump from a file, taking care -of the specified revision range. -To simulate incremental imports the environment variable SVNRMAX can be set -to the highest revision that should be available. -""" -import sys -import os - -if sys.hexversion < 0x02040000: - # The limiter is the ValueError() calls.
