[GUI Plugin] Quality Check

[theducks]

Calibre 5.2 and Quality check PI, Check Metadata is behaving odd.
When I ran Check Author Sort or Check Title Sort it NOW is very bursty
(does a bunch, pauses, does more. overall, a lot slower)

[un_pogaz]

I just had an idea for a new feature :
Check if the ePub contain a another ePub file.

It may be extremely specific, but I've come across far too many books with this that I'm looking for a reliable way to hunt them down.
Thanks

What ePub has another ePub? I've never see this. can you point out some eBooks that have this?

I can't give any specifics name. but I saw her. I don't know where it comes from, but, it's a real pain in the ass.
This kind of thing can make an ePub get really big.
original ePub < 500 kb
inner ePub > 4 MB

And in fact... I managed to modify my Quality Check to include the feature.

Code
config.py

       ('check_epub_inside_epub',  {'name': 'Check ePub inside ePub',             'cat':'epub',     'sub_menu': 'Check ePub Structure',     'group': 3, 'excludable': True,  'image': 'images/check_book.png',        'tooltip':'Check for ePub formats containing a ePub inside'}),

check_epub.py

EPUB_FILES = ['.epub']
ALL_ARTIFACTS = ITUNES_FILES + BOOKMARKS_FILES + OS_FILES + EPUB_FILES

...

    def perform_check(self, menu_key):

...

        elif menu_key == 'check_epub_inside_epub':
            self.check_epub_inside_epub()

...
...

    def check_epub_inside_epub(self):

        def evaluate_book(book_id, db):
            path_to_book = db.format_abspath(book_id, 'EPUB', index_is_id=True)
            if not path_to_book:
                self.log.error('ERROR: EPUB format is missing: ', get_title_authors_text(db, book_id))
                return False
            try:
                found = False
                displayed_path = False
                with ZipFile(path_to_book, 'r') as zf:
                    for resource_name in self._manifest_worthy_names(zf):
                        extension = resource_name[resource_name.rfind('.'):].lower()
                        if extension in EPUB_FILES:
                            if not displayed_path:
                                displayed_path = True
                                self.log('ePub found in: <b>%s</b>'%get_title_authors_text(db, book_id))
                            self.log('\t<span style="color:darkgray">%s</span>'%resource_name)
                            found = True
                return found

            except InvalidEpub as e:
                self.log.error('Invalid epub:', e)
                return False
            except:
                self.log.error('ERROR parsing book: ', path_to_book)
                self.log(traceback.format_exc())
                return False

        self.check_all_files(evaluate_book,
                             no_match_msg='No searched ePub books have a ePub inside',
                             marked_text='epub_inside_epub',
                             status_msg_type='ePub books with a ePub inside')

A good listener, Chalut

EDIT: I realize that FONT_FILES does not include '.woff' and '.woff2'. It's true that the formats are recent and not supported on all reader, but they have become very common and I wouldn't be surprised to see them appear in a ePub.

Small request: Could it be possible to use ellides (...) for lengthy titles in the progress dialog? I have a book with an extremely lengthy title and after QC processes it the dialog becomes wide enough to push the Cancel button off-screen.

My guess is, he/she is just talking about an omnibus.

But that's not an ePub within an ePub. An ePub within an ePub would be a ePub eBook inside the first ePub and that I've never seen or heard of before this thread. If that's not what's meant, then please explain what's meant and how to detect whatever it is.

[ownedbycats]

Some sort of packaging error? I've never seen one myself.

Can you point to an example? I have never seen an epub within an epub like you seem to be describing. I don't know if it is allowed by the epub specs or is a packaging error as @ownedbycats. About the only thing I can think of is a zip file containing epubs that was added to calibre and it decided to treat it as an epub. Calibre does look at the contents of zip files when they are added to see if they should be treated as something else.

I didn't see this in the list of features, but this plugin can do alot. So this is a question or feature request. Can QC check for epubs that would trigger the Nook cover bug?

https://nachtimwald.com/2011/08/21/n...ot-showing-up/

Nooks have an issue where the attributes have to be in a specific order.

I know I can fix this with calibre by doing a polish epub, or embed metadata. But I'd rather not update every file if I don't have to.

Thanks.

Sorry, but you'll have to edit each file.

I've seen exactly one. The epub creator manually created the .zip container since she "wanted complete control over the process". FlightCrew and EpubCheck went wild showing error messages after I sucked the file into Sigil.

I found that I can "Search ePubs" with the expression

content="[^"]+"\s+name="cover"

and search in OPF only and I will find matches that I want.

Hello people, I have taken the plight of translating the complement into Spanish and creating antecedents for other languages. I leave the file and some samples for future updates

I can release this version but I am not interested in fixing problems or maintaining it. @dunhill: are you willing to maintain this plugin, at least to fix issues with translations? I don't mean incorrect translations. I do mean fixing problems that cause the plugin to no longer work.
