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.
The functionality of --(chapter-)filter and --(chapter-)range are now
also exposed as the following config-file options:
- extractor.*.image-filter
- extractor.*.image-range
- extractor.*.chapter-filter
- extractor.*.chapter-range
TODO: update configuration.rst
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.
A format string now gets parsed only once instead of re-parsing it each
time it is applied to a set of data.
The initial parsing causes directory path creation to be at about 2x
slower than before, since each format string there is used only once,
but building a filename, the more common operation, is at least 2x
faster. The "directory slowness" cancels at about 5 filenames and
everything above that is significantly faster.
- cache manga API results
- add artist, author and date fields to chapter metadata
- remove Manga-/ChapterExtractor inheritance
- minor code simplifications and improvements
The L option allows for the contents of a format field to be replaced
with <replacement> if its length is greater than <maxlen>.
Example:
{f:L5/too long/} -> "foo" (if "f" is "foo")
-> "too long" (if "f" is "foobar")
(#92) (#94)
It is now possible to slice string (or list) values of format string
replacement fields with the same syntax as in regular Python code.
"{digits}" -> "0123456789"
"{digits[2:-2]}" -> "234567"
"{digits[:5]}" -> "01234"
The optional third parameter (step) has been left out to simplify things.
DeviantArt changed its URL format from
https://<name>.deviantart.com/...
to
https://www.deviantart.com/<name>/...
With this change both formats will be supported.
The API endpoint responsible for user illustrations does not
provide sufficient filter capabilities* to match the actual
website, so we are spinning our own filters.
Respected parameters are
'type': illust, manga, ugoira
'tag' : any image tag (this was already supported)
'p' : the page to start on
*
- API can filter for illustrations and manga, but not for ugoira.
- 'offset' is applied before filtering
- no 'tag' filter
OAuth support for SmugMug needs some additional features
(auth-rebuild on redirect, query parameters in URL, ...)
and fixing this in the old code wouldn't work all that well.
Pinterest access tokens are rate limited at 200 requests per
hour (or maybe per 2 or 3 hours?) so having just one access token
for all users isn't going to work in the long run.
- another irrelevant micro-optimization !
- use urllib.parse.parse_qsl directly instead of parse_qs, which
just packs the results of parse_qsl in a different data structure
- reduced memory requirements since no additional dict and lists are
created

calling 'abort()' in a filter aborts the current extractor run
in a cleaner way than using something like 1/0, which
causes an error message to be printed
https://img.yt/ wasn't available for a couple of days, but has now
re-emerged as https://imx.to/ with a new web-interface.
Links to older images still work (see tests).
- fix the cloudflare challenge result if the last decimal places
are zero (JS`s toFixed() removes trailing zeroes)
- fix downloading of kissmanga chapter-pages hosted on blogspot
(accessing blogspot with "kissmanga.com" as referrer yields a 401)
- disable certificate validation for 'mangahere' tests
- update flickr test result
Python3.5 and lower throw an UnicodeEncodeError when trying to print
not-encodable characters when not using 'utf-8' as encoding.
Setting their error handlers to 'replace' should help.
... to behave in a more straightforward way when dealing with
bookmarks/favourites/etc.
specific IDs are now grouped by their owner, album-id, ... to
allow for duplicates when it would be expected.
Missing or undefined keywords will now be replaced with the value
set for 'keywords-default'. The default is Python's 'None', which
is equivalent to setting this option to JSON's 'null'.
Instead of a dictionary/object, input file options are now specified
by a 'key=value' pair starting with '-' for options only applying to
the next URL or '-G' for Global options applying to all following URLs.
See the docstring of parse_inputfile() for details.
Example option specifiers:
- filename = "{id}.{extension}"
- extractor.pixiv.user.directory = ["Pixiv Users", "{user[id]}"]
-spaces="are_optional"
-G keywords = {"global": "option"}
- "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,
}
Some user galleries [*] require you to be either logged in or
authenticated via OAuth2 to access their deviations.

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.
Due to API restrictions and/or missing knowledge about and
documentation of API usage, it was only possible to retrieve the
latest 200 images of a niconico seiga user with said API.
The new approach manually visits each HTML page and gets its
information from there.
- add wait-time between HTTP requests similar to exhentai
- add 'wait-min' and 'wait-max' options
- increase retry-count for HTTP requests to 10
- implement user authentication (non-authenticated users can only view
images up to page 25)
- implement 'skip()' functionality (only works up to page 50)
- implement image-retrieval for pages >= 51
- fix issue with multiple tags
This allows for image filtering via Python expressions by the same
metadata that is also used to build filenames (--list-keywords).
The usually shunned eval() function is used to evaluate
filter-expressions, but it seemed quite appropriate in this case and
shouldn't introduce any new security issues, as any attacker that could do
> gallery-dl --filter "delete-everything()" ...
could as well do
> python -c "delete-everything()"
Metadata of several year old lists shouldn't change as much as it
would for newer ones, which makes metadata-comparisons of the output
of build_testresult_db.oy easier.
- user.deviantart.com/(gallery|favourites|journal)/ images go into
* <user>/
* <user>/Favourites/
* <user>/Journal/
(having an extra "Gallery" folder for a user's gallery-images seems
a bit too much if these are all you want to download, which is
probably the default use-case)
- single "deviations" (user.deviantart.com/(art|journal)/name-123) go
into their owner's directory:
* <user>/
(putting them into their own directory seems weird in practice)
the 'skip' config option controls skipping behavior:
true - skip download if file already exist (default)
false - download and overwrite files even if it exists
"abort" - abort extractor run if a download would be skipped
(same as '--abort-on-skip')
- 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'
- speed improvements, especially in the 'interpolate' function
- 'interpolate' now prioritizes base-level values if they exist
- "username" is chosen before "extractor.<category>.username"
- -u/--username & co can now override config-file values
- this includes dokireader, fallenangels, jaiminisbox, powermanga,
sensescans, worldthree, yonkouprod, gomanga, yomanga
- added 'chapter_string', 'chapter_id', 'chapter_minor' and 'count'
keywords
- changed the 'chapter' keyword to always be just a number
- changed the default directory format
- fixed html.unescape not being available on Python3.3
- removed inconsistent test result
- added username/password pairs for authenticating extractors
