1 #! /usr/bin/env python 2 3 """ 4 SVN helper script. 5 6 Try to set the svn:eol-style property to "native" on every .py, .txt, .c and 7 .h file in the directory tree rooted at the current directory. 8 9 Files with the svn:eol-style property already set (to anything) are skipped. 10 11 svn will itself refuse to set this property on a file that's not under SVN 12 control, or that has a binary mime-type property set. This script inherits 13 that behavior, and passes on whatever warning message the failing "svn 14 propset" command produces. 15 16 In the Python project, it's safe to invoke this script from the root of 17 a checkout. 18 19 No output is produced for files that are ignored. For a file that gets 20 svn:eol-style set, output looks like: 21 22 property 'svn:eol-style' set on 'Lib\ctypes\__init__.py' 23 24 For a file not under version control: 25 26 svn: warning: 'patch-finalizer.txt' is not under version control 27 28 and for a file with a binary mime-type property: 29 30 svn: File 'Lib\test\test_pep263.py' has binary mime type property 31 """ 32 33 import re 34 import os 35 36 def propfiles(root, fn): 37 default = os.path.join(root, ".svn", "props", fn+".svn-work") 38 try: 39 format = int(open(os.path.join(root, ".svn", "format")).read().strip()) 40 except IOError: 41 return [] 42 if format in (8, 9): 43 # In version 8 and 9, committed props are stored in prop-base, local 44 # modifications in props 45 return [os.path.join(root, ".svn", "prop-base", fn+".svn-base"), 46 os.path.join(root, ".svn", "props", fn+".svn-work")] 47 raise ValueError, "Unknown repository format" 48 49 def proplist(root, fn): 50 "Return a list of property names for file fn in directory root" 51 result = [] 52 for path in propfiles(root, fn): 53 try: 54 f = open(path) 55 except IOError: 56 # no properties file: not under version control, 57 # or no properties set 58 continue 59 while 1: 60 # key-value pairs, of the form 61 # K <length> 62 # <keyname>NL 63 # V length 64 # <value>NL 65 # END 66 line = f.readline() 67 if line.startswith("END"): 68 break 69 assert line.startswith("K ") 70 L = int(line.split()[1]) 71 key = f.read(L) 72 result.append(key) 73 f.readline() 74 line = f.readline() 75 assert line.startswith("V ") 76 L = int(line.split()[1]) 77 value = f.read(L) 78 f.readline() 79 f.close() 80 return result 81 82 possible_text_file = re.compile(r"\.([hc]|py|txt|sln|vcproj)$").search 83 84 for root, dirs, files in os.walk('.'): 85 if '.svn' in dirs: 86 dirs.remove('.svn') 87 for fn in files: 88 if possible_text_file(fn): 89 if 'svn:eol-style' not in proplist(root, fn): 90 path = os.path.join(root, fn) 91 os.system('svn propset svn:eol-style native "%s"' % path) 92
