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().
Instead of replacing 'https' with 'http' for every URL in
'get_downloader()', this now only happens once during downloader
initialization. Also unit tests.
The "default" downloader options (rate, retries, timeout, verify) are
mapped to corresponding youtube-dl options.
downloader.ytdl.logging tells the downloader to pass youtube-dl's output
to a Logger object.
downloader.ytdl.raw-options allows to pass arbitrary options to the
YoutubeDL constructor.
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.
URLs starting with 'ytdl:' will now be handled by youtube-dl.
There is probably a lot to fix and improve, but the basic use case
works.
TODO:
- format selection and ytdl options in general
- better filename/path handling
- ytdl support for "unsupported URLs"
- ...
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.)
- '--no-part' command line option to disable them
- 'downloader.http.part' and 'downloader.text.part' config options
Disabling .part files restores the behaviour of the old downloader
implementation.
There was never any "good" reason for the strict separation
between extractors and downloaders. This change allows for
reduced resource usage (probably unnoticeable) and less lines
of code at the "cost" of tighter coupling.
- remove support for old windows config paths
- catch exception if cache-database can't be opened
- fix username/password settings for unit tests
- rename variable 'max_tries' to 'retries'
