Fix WGWrongCodeError Exceptions Being Thrown#12

I was running into attributes not existing on the WGWrongCodeError object causing exceptions when avatars were 404'ing on Tumblr posts, which also caused those posts not to be saved. Just added a couple lines to check for the attributes' existence, which has fixed the exceptions on my end and appears to be saving the posts despite the avatar 404s. Further details below, in case there's a better way than my solve: `python ./tumblr_backup.py -O ../blogs_tumblr/blogname --json --save-video-tumblr --save-audio --save-notes --notes-limit 100 --tag-index -N 0 --no-post-clobber --internet-archive --reuse-json blogname` ``` Caught exception while saving post 5357295512: Traceback (most recent call last): File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 635, in _retrieve_loop err, doctype = gethttp(url, hstat, doctype, logger, retry_counter, options) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 253, in gethttp err, doctype = process_response(url, hstat, doctype, logger, retry_counter, resp) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 340, in process_response raise e wget.WGWrongCodeError: WGWrongCodeError(<wget.Logger object at 0x7f5338400f50>, 'https://64.media.tumblr.com/avatar_f76a691e3bd3_1280.png', 404, 'Not Found', HTTPHeaderDict({'Server': 'nginx', 'Date': 'Sat, 25 Nov 2023 00:28:12 GMT', 'Content-Type': 'text/plain', 'Content-Length': '14', 'Connection': 'keep-alive', 'ETag': '"655cda67-e"', 'X-nc': 'HIT dfw 1', 'Access-Control-Allow-Methods': 'GET', 'Access-Control-Allow-Origin': '*', 'Access-Control-Max-Age': '86400', 'Strict-Transport-Security': 'max-age=31536000; preload', 'Server-Timing': 'dc;desc=dfw, cache;desc=HIT;dur=0.0'})) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1808, in _download_media_inner wget_retrieve(url, dstpath, post_id=self.ident, post_timestamp=self.post['timestamp']) File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 801, in __call__ _retrieve_loop(hstat, url, file, post_id, post_timestamp, adjust_basename, self.options, self.log) File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 684, in _retrieve_loop raise oe wget.WGWrongCodeError: WGWrongCodeError(<wget.Logger object at 0x7f5338400f50>) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1960, in save_post f.write(self.get_post()) ^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1838, in get_post content = self.get_content() ^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1521, in get_content append_try('body') File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1505, in append_try elt = re.sub(r'''(?i)(<img\s(?:[^>]*\s)?src\s*=\s*["'])(.*?)(["'][^>]*>)''', ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/re/__init__.py", line 185, in sub return _compile(pattern, flags).sub(repl, string, count) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1690, in get_inline_image saved_name = self.download_media(image_url, filename=image_filename) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1782, in download_media return self._download_media_inner(url, get_path, path_parts, media_path) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/./tumblr_backup.py", line 1810, in _download_media_inner e.log() File "/home/lucible/nas-home/archives/archive/tumblr-utils_cebtenzzre/wget.py", line 507, in log self.logger.error(self.url, self.msg, info) ^^^^^^^^ AttributeError: 'WGWrongCodeError' object has no attribute 'msg' ```
