Reviews and operations on the backend that support undoing can now be
committed immediately, so they will not be lost in the event of a crash.
This required tweaks to a few places:
- don't set collection mtime on save() unless changes were made in
Python, as otherwise we end up accidentally clearing the backend undo
queue
- autosave() is now run on every reset()
- garbage collection now runs in a timer, instead of relying on
autosave() to be run periodically
- use dataclasses for the review/checkpoint undo cases, instead of the
nasty ad-hoc list structure
- expose backend review undo to Python, and hook it into GUI
- redo is not currently exposed on the GUI, and the backend can only
cope with reviews done by the new scheduler at the moment
- the initial undo prototype code was bumping mtime/usn on undo, but
that was not ideal, as it was breaking the queue handling which expected
the mtime to match. The original rationale for bumping mtime/usn was
to avoid problems with syncing, but various operations like removing
a revlog can't be synced anyway - so we just need to ensure we clear the
undo queue prior to syncing
That way, the caller doesn't have to hold a reference to the browser and
explicitly call it again, if it wants to search for something specific.
Also, if the browser was closed and opened for a single-card-search, it
now won't perform a redundant current-deck-search first.
When opening a dialogue accepting multiple optional arguments, relying
on position is error-prone and requires passing Nones to fill unused
parameter slots.
- Handle deck building inside class. New deck is built unless caller
passes filtered deck.
- If no deck is passed and current deck is filtered, copy settings.
- Remove exec_().
- anki._backend stores the protobuf files and rsbackend.py code
- pylib modules import protobuf messages directly from the
_pb2 files, and explicitly export any will be returned or consumed
by public pylib functions, so that calling code can import from pylib
- the "rsbackend" no longer imports and re-exports protobuf messages
- pylib can just consume them directly.
- move errors to errors.py
Still todo:
- rsbridge
- finishing the work on rsbackend, and check what we need to add
back to the original file location to avoid breaking add-ons
- Remove _searchPrompt.
- Add placeholder prompt.
- Move search for current card from browser to caller. (Thus, support
current card search even with opened browser.)
- notes with wrong field count are now recovered instead of
being deleted
- notes with missing note types are now recovered
- notes with missing cards are now recovered
- recover_missing_deck() still needs implementing
- checks required
If the schema confirmation dialog is shown on a background thread it
will crash the app, so we convert this to an assertion error that gets
caught by the error handler. Code still needs to be updated to modify
the schema prior to moving to the background, but at least this way
it doesn't crash.
- field changes are now applied when user closes dialog with save
button, in bulk
- models diag now fetches note type and saves it as required, instead
of holding on top a copy that can grow stale as changes are made in
subdialogs
- both dialogs now perform operations in the backend
- note.model() now fetches the note type on the fly, instead of
holding on to a copy that may become stale
This will allow, for example, for add-ons to do self.debugDiag.text
and access the debugger text. I see very little reason to have a
direct access to the dialog window.
I should note that self.debugDiag is never used anywhere in the code,
so I think it should be deleted; unless you've heard of some add-on
using it.
- A regular collection open/close no longer goes through the
upgrade/downgrade steps each time. This avoids wasted cycles, and will
become more important in the future when decks and note types are
split into separate tables.
- Added a downgrade button to the profiles screen to downgrade all
profiles and close the app.
- Downgrading is still automatic when exporting/doing a full sync.
