This refactors things such that
* Fetching the ugoira frame data happens at the end of rewrite, not
rewrite_html_pages. This way uploading zip URLs should work.
* The source data is cached in an instance variable in case it
was indeed fetched during rewrite_html_pages. This way it doesn't get
fetched a second time.
file.get_input_stream leaves the file open by default, which means the
zip cannot be moved later on. But the block version of it closes the
file automatically.
mkvmerge didn't realize it was supposed to output a webm specifically
because write_path does not have a file extension. The --webm option
tells it this instead.
Some browsers like Chrome (and some video players like MPC-HC) do not
display the last frame of a webm (or they display it, but only very
briefly) if set to loop. This commit is a hack to force the last frame
to display for the correct amount of time by duplicating it.
* Fix regex for getting frame data not working if agent is logged in to
pixiv
* Fix #unpack not returning the unpacked folder
* Fix frame_data being inaccessible because it was a local variable
* Fix images getting put in tmpdir, when they're expected to be in
tmpdir/images
* Fix deleting the tmpdir manually (it gets deleted automatically)
* Fix output webm being put in tmpdir (which gets deleted) instead of
write_path
Refactors things such that Sources::Site has a normalize_for_artist_finder!
method that delegates to the strategy for the appropriate site. This way
any site that needs to normalize URLs for the artist finder can do so.
There are two kinds of thumbnails that need to be rewritten. First case:
new /img-master/ URLs need to be rewritten to /img-original/ URLs like this:
http://i2.pixiv.net/c/600x600/img-master/img/2014/10/04/03/59/52/46337015_p0_master1200.jpg
=> http://i2.pixiv.net/img-original/img/2014/10/04/03/59/52/46337015_p0.png
This is what `rewrite_new_medium_images` does. In order to do this, it
has to use the Pixiv API to get the correct file extension.
Second case: Old small/medium size URLs need to be rewritten to full
size URLs like this:
http://i2.pixiv.net/img18/img/evazion/14901720_m.png
=> http://i2.pixiv.net/img18/img/evazion/14901720.png
But when the medium size URL is actually for a manga image, it needs to be
rewritten to the big manga URL instead:
http://i2.pixiv.net/img04/img/syounen_no_uta/46170939_m.jpg
=> http://i2.pixiv.net/img04/img/syounen_no_uta/46170939_big_p0.jpg
But we can't tell whether it's a manga image from the URL, so we have to
use the manga page count from either the HTML page or the API to
determine whether it's part of a manga gallery.
So in order to make this work, `rewrite_old_small_and_medium_images`
takes an `is_manga` flag. `Sources::Strategies::Pixiv#get` gets the
page count from the HTML and passes the `is_manga` flag on down through
the call chain until `rewrite_old_small_and_medium_images` gets it.
When `rewrite_old_small_and_medium_images` is called from
`Downloads::Strategies::Pixiv#rewrite_thumbnails`, the `is_manga` flag
isn't passed in because we didn't scrape the HTML. This causes
`rewrite_old_small_and_medium_images` to look it up in the API instead.
