"Fluent Python, 2nd Edition" is one book with a field for the edition. Left in
the title it also splits the library, since the second edition never looks like
the first. Only a numbered statement is moved, so "Catch 22" keeps its number
and "Global Edition" — which has nowhere to go in an integer column — stays put.
Identifiers are a collection, but the whole dict was replaced per format, so
the last file to report won outright — an EPUB declaring an ASIN, a Google id
and a Calibre id kept none of them once a PDF contributed one ISBN. Accumulate
instead, letting a declared identifier outrank one scraped off a page.
Extractors wrote whatever the file said, so one person held several rows:
"Sam Newman" beside "Newman, Sam;" beside "Sam Newman.epub", the last because
the upload path never stripped the file extension. Tidy on write, in the
validator and in the uniqueness lookup alike, and merge the rows that collide.
"Building Microservices, 2E" never matched "Building Microservices". Key the
strip on the trailing "e" so 2E, 5e and 3 Ed are caught, while a bare number
leaves "Catch 22" and "Blade Runner 2049" alone. Stored keys are recomputed.
Match on a shared identifier, or on a normalised title credited to a shared
author, and report candidates rather than refusing anything — a metadata match
is a guess, and a second edition is not a mistake. Adds a library-wide review
pass, dismissals, and renames the fingerprint pre-flight to duplicate-files.
Derive normalized_title, normalized_name and normalized_value with @validates
so no write can bypass them, and add the table recording pairs a reader has
said are not the same book.
DC:identifier was validated verbatim, so hyphenated and urn:isbn: forms never
reached the checksum and every non-ISBN identifier was discarded. Normalise
first, and name whatever survives.
Reduce a title, an author and an identifier to a single comparison key, so
two copies of one book can be recognised by equality rather than by a
similarity score.
The hash lives in the database and the file does not, so a file deleted behind
the app's back went on refusing its own replacement. Matches are now checked
against disk, and re-adding a book's own missing file writes it back into the
row that already describes it.
Incoming files are matched against what is already stored, keyed on the
KOReader hash and the file size. Bulk uploads skip and report them, deliberate
creates are refused with a 409, the consume directory parks them aside, and
allow_duplicates overrides all three.
Also: books whose metadata generates a path another book already owns are moved
aside, so a forced copy cannot overwrite the original's files.
The filepath extractor was merged on the right, so a parent folder's name
overrode the title inside the file. Grouping also split a book's formats when
its own folder was the upload root.
file.path is relative to book.path, so the archive matched nothing on disk and
came out empty. Also namespace entries per book to stop filename collisions, and
stream the zip instead of buffering it whole.
Assigning through the association proxy recreated links for targets the book
already had, colliding with the link tables' unique constraints. Reconcile the
collections in place instead, identifiers included.
Implement KOReader's partial MD5 algorithm for document identification. This hash allows KOReader devices to match local files with server records for reading progress synchronization (KOSync).
Books may not have a path (e.g., physical books, metadata-only entries).
Updated path-dependent operations to handle None gracefully:
- get_file: raise ValueError if book has no path
- update_book: skip path relocation if no path exists
- remove_files: skip filesystem cleanup if no path exists
Also fixed _save_book_files return type and removed unused imports.
The create, update, and delete methods had incompatible signatures
resulting in typecheck errors. Renamed to create_book, update_book, and
delete_books.
The Darwin epub test cases used absolute paths. I hadn't notices until switching machines, whcih caused errors in the test harness. Changed to relative paths to be consistent with other test cases.
Updated book progress model in anticipation of the KOReader sync
feature.
Renamed properties:
- renamed "progress" to "percentage"
- renamed "pdf_loc" to "pdf_page"
- renamed "epub_loc" to "epub_cfi"
New properties:
- "epub_xpointer", marks the location of an epub in KOReader
- "device", the device type that updated the progress
- "device_id", the id of the device that updated the progress
