The RE-tries option now specifies exactly that: the maximum number a
failed HTTP request is re-tried. For example a value of 2 will now
correctly stop after 3 attempts: the initial one + 2 re-tries.
The maximum wait-time now also caps at 30min and increases exponentially
for both extractor.request() and downloader.http.download().
Cloudflare now also checks the client's SSL/TLS cipher capabilities and
produces a 403: Forbidden response with CAPTCHA if they are insufficient.
This commit replaces the default cipher list in urllib3 < 1.25 with the
one from 1.25 (1), which doesn't cause problems as long as the client
platform actually supports these ciphers. On some platforms (tested with
Python 3.4 on Linux and Python 3.7 on an outdated Windows 7 VM) it is
necessary to install pyOpenSSL to get everything to work.
Explicitly setting a minimum/maximum version for urllib3 is also no
longer necessary and installing gallery-dl will therefore not pull a
incompatible urllib3 version (#229)

Instead of getting a complete 'filename' from an URL and splitting that
into 'name' and 'extension', the new approach gets rid of the complete
version and renames 'name' to 'filename'. (Using anything other than
{extension} for a filename extension doesn't really work anyway)
Example: "https://example.org/path/filename.ext"
before:
- filename : filename.ext
- name : filename
- extension: ext
now:
- filename : filename
- extension: ext
Instead of a strict list of (URL, RESULTS)-tuples, extractor result
tests can now be a single (URL, RESULTS)-tuple, if it's just one test,
and "only matching" tests can now be a simple string.
from: 5xx HTTP Error: Reason
to : 5xx: Reason
The "HTTP Error" part was in there to emulate Request's error messages
from response.raise_for_status(), but it reads a lot better without.
This change introduces 'extractor.*.retries/timeout/verify' options
as a general way to set these values for all HTTP requests.
'downloader.http.retries/timeout/verify' is a way to override these
options for file downloads only and will fall back to 'extractor.*.…*
values if they haven't been explicitly set.
Also: downloader classes now take an extractor object as first argument
instead of a requests.session.
