|

| 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
