+def to_bytes(str):<br>
+ # Encode to UTF-8 to get binary data.<br>
----------------<br>
Pretty much a nit but using variable names that match type names can be a bit confusing here.<br>
<br>
<br>
================<br>
Comment at: tools/clang-format/git-clang-<wbr>format:302<br>
<span class="">+ return bytes<br>
+ return to_bytes(bytes)<br>
</span>+<br>
----------------<br>
Shouldn't this be:<br>
<br>
return bytes.decode('utf-8')<br>
<br>
?<br>
<br>
Otherwise, unless I'm missing something this function will always return the parameter [with no modifications], either in the first conditional if it's of `str` type, or in the conditional inside `to_bytes()` if it's of `bytes` type.<br>
<br>
<br>
================<br>
Comment at: tools/clang-format/git-clang-<wbr>format:306<br>
+ try:<br>
+ return to_string(bytes.decode('utf-8'<wbr>))<br>
+ except AttributeError: # 'str' object has no attribute 'decode'.<br>
----------------<br>
This logic looks really weird to me. What is the purpose of having both `to_string()` and `convert_string()`? Why do `to_bytes()` and `to_string()` use `isinstance()` to recognize types, and here you rely on exceptions? Why is `to_string()` called after decoding?<br>
<br>
<br>
================<br>
Comment at: tools/clang-format/git-clang-<wbr>format:310<br>
+ except UnicodeError:<br>
+ return str(bytes)<br>
+<br>
----------------<br>
I don't think this can ever succeed. If the argument is not valid utf8, it certainly won't be valid ASCII.<br>
<span class=""><br>

</span> for line in patch_file:<br>
- match = re.search(r'^\+\+\+\ [^/]+/(.*)', line)<br>
+ match = re.search(to_bytes(r'^\+\+\+\ [^/]+/(.*)'), line)<br>
if match:<br>
----------------<br>
Any reason not to use:<br>
<br>
br'^\+...'<br>
<br>
? i.e. make it bytes immediately instead of converting.<br>
<br>
<br>
================<br>
Comment at: tools/clang-format/git-clang-<wbr>format:344<br>
+ keys_to_delete = []<br>
<span class="">+ for filename in list(dictionary.keys()):<br>
</span>+ filename_cp = convert_string(bytes(filename)<wbr>)<br>
----------------<br>
Since you are using `keys_to_delete` now, you can remove the `list()`.<br>
<br>
<br>
================<br>
Comment at: tools/clang-format/git-clang-<wbr>format:348<br>
if len(base_ext) == 1 or base_ext[1].lower() not in allowed_extensions:<br>
- del dictionary[filename]<br>
+ keys_to_delete += [filename]<br>
+ for key in keys_to_delete:<br>
----------------<br>
Another nit. I think it'd be better to just append a single item instead of a list of 1 item ;-).<br>
<br>
keys_to_delete.append(<wbr>filename)<br>
