Copy all subversion properties on directories and files from one source tree to another identical source tree

Friday, 26 February 2010 01:44

Copy all subversion properties on directories and files from one source tree to another identical source tree.

Works well for copying between two revisions of a vendor library where a new directory is used for each revision. For example, svncopyprop openssl/0.9.8l openssl/0.9.8m

Works on Windows. Expect that it should work on Linux as well.

# This script will copy all subversion properties from one source tree

# to another identical source tree. It is best for copying between

# revisions of a vendor library. e.g. /openssl/0.9.8l -> /openssl/0.9.8m

# Usage: svncopyprop SRC DST

    pnames = out.split()

    

    for pname in pnames:

        out = myexec(['svn', 'pg', '--strict', pname, src], False)

        with file(mytempfile, 'wt') as f:

            out = '\n'.join(out.split())

            f.write(out)

        myexec(['svn', 'ps', pname, dst, '--file', mytempfile], True)



    if os.path.isdir(src): 

        for subdir in os.listdir(src):

            if subdir == '.svn': continue

            nsrc = os.path.join(src, subdir)

            ndst = os.path.join(dst, subdir)

            svncopyprop(nsrc, ndst)

    

svncopyprop(sys.argv[1], sys.argv[2])

os.remove(mytempfile)
