Long paths on Windows lead to errors due to shutil limitations #156
Description
Describe the bug
The bug occurs when shutil is trying to delete files with really long paths whilte the EnableLongPaths registry entry is not set.
File "...\Python310\Lib\site-packages\doxysphinx\utils\files.py", line 143, in copy_if_different
shutil.copy(source_file, target_file)
File "shutil.py", line 417, in copy
File "shutil.py", line 256, in copyfile
FileNotFoundError: [Errno 2] No such file or directory: 'super\duper\long\path\filename_icgraph.map'
To Reproduce
Steps to reproduce the behavior:
- Create a really long base path for your project (>260 characters)
- Run doxygen
- Run doxysphinx
Expected behavior
The file shuld be handled properly.
Desktop (please complete the following information):
- OS: Windows 10
Additional context
This can be solved enabling long file paths programmatically: https://burgaud.com/path-too-long/
I was able to fix the issue transforming the paths if running doxysphinx on Windows:
files.py:135 ff
result: List[Path] = []
for file in files_to_copy:
source_file = file
target_file = target_dir / source_file.relative_to(source_dir)
target_file.parent.mkdir(parents=True, exist_ok=True)
if os.name == 'nt':
source_file = r"\\?\%s" % source_file
target_file = r"\\?\%s" % target_file
shutil.copy(source_file, target_file)
result.append(target_file)
return result
