- "count" can now be a string defining a comparison in the form of
'<operator> <value>', for example: '> 12' or '!= 1'. If its value
is not a string, it is assumed to be a concrete integer as before.
- "keyword" can now be a dictionary defining tests for individual keys.
These tests can either be a type, a concrete value or a regex
starting with "re:". Dictionaries can be stacked inside each other.
Optional keys can be indicated with a "?" before its name.
For example:
"keyword:" {
"image_id": int,
"gallery_id", 123,
"name": "re:pattern",
"user": {
"id": 321,
},
"?optional": None,
}
This allows the DeviantArt group-check to be moved inside the
Extractor.items() method which in turn allows for better exception
handling.
As a new general rule:
Never raise exceptions during extractor initialization.
Gelbooru's API allows access to all images and is not restricted
to the first 20000.
This also adds an option to select between API use and manual
information extraction in case their API gets disabled again.
The 'refresh_token' set in a user's config file gets used once to
get a new 'access_token' and 'refresh_token', which is then stored
in gallery-dl's cache and gets used the next time the 'access_token'
needs to be refreshed.
This means deleting the cache file invalidates the refresh_token-
chain and requires the user to re-authenticate.
Some user galleries [*] require you to be either logged in or
authenticated via OAuth2 to access their deviations.
[*] e.g. https://polinaegorussia.deviantart.com/gallery/
--------------
known issue:
A deviantart 'refresh_token' can only be used once and gets updated
whenever it is used to request a new 'access_token', so storing its
initial value in a config file and reusing it again and again is not
possible.
This commit changes the general behavior from
'Retry on every exception and abort on DownloadError' to
'Only retry on DownloadRetry exceptions and abort on every other one'
The previous version would have retried on several states which
would have no chance of ever succeeding (invalid URLs, etc.)
