remove unreachable links by python scripts:
```
def is_delete_issue(link):
try:
response = requests.get(link)
except RequestException as e:
print(f"An error occurred while trying to get the link: {e}")
return False
return "This issue has been deleted." in response.text
def remove_unreachable_links(dir):
string_to_search = re.compile(r'// @see https://github\.com/ossrs/srs/issues/.*')
file_list = util.find_files_with_extension(dir, ".cpp", True)
for file in file_list:
lines = []
with open(file, "r", encoding="utf-8") as f:
lines = f.readlines()
with open(file, "w", encoding="utf-8", newline="\n") as f:
for line in lines:
if string_to_search.search(line):
result = re.search(r'https://github\.com/ossrs/srs/issues/\d+', line)
if result:
link = result.group()
if is_delete_issue(link):
print("is_delete_issue link: file: %s, line: %s" % (file, line))
continue
f.write(line)
