The old Python code was only checking for NFC encoding, but we should
check for other issues like special filenames on windows (eg con.mp3)
- On export, the user is told to use Check Media if their media has
invalid filenames.
- On import, legacy packages will be transparently normalized. Since we're
doing the checks on export as well, any invalid names in a v3 package
are an error.
* Fix legacy colpkg import; disable v3 import/export; add roundtrip test
The test has revealed we weren't decompressing the media files on v3
import. That's easy to fix, but means all files need decompressing
even when they already exist, which is not ideal - it would be better
to store size/checksum in the metadata instead.
* Switch media and meta to protobuf; re-enable v3 import/export
- Fixed media not being decompressed on import
- The uncompressed size and checksum is now included for each media
entry, so that we can quickly check if a given file needs to be extracted.
We're still just doing a naive size comparison on colpkg import at the
moment, but we may want to use a checksum in the future, and will need
a checksum for apkg imports.
- Checksums can't be efficiently encoded in JSON, so the media list
has been switched to protobuf to reduce the the space requirements.
- The meta file has been switched to protobuf as well, for consistency.
This will mean any colpkg files exported with beta7 will be
unreadable.

* Add export_colpkg() method to Collection

Currently colpkg/*.rs contain some routines that will be useful for

* Return a proper error when media import fails
This tripped me up when writing the earlier unit test - I had called
the equivalent of import_colpkg()?, and it was returning a string error
that I didn't notice. In practice this should result in the same text
being shown in the UI, but just skips the tooltip.

On collections with lots of media, it can grow into megabytes.

it as an optional.
* Store media map as a vector in the v3 package (dae)
This compresses better (eg 280kb original, 100kb hashmap, 42kb vec)
In the colpkg import case we don't need random access. When importing
an apkg, we will need to be able to fetch file data for a given media
filename, but the existing map doesn't help us there, as we need
filename->index, not index->filename.
* Ensure folders in the media dir don't break the file mapping (dae)
Ideally this would have been in beta 6 :-) No add-ons appear to be
using customstudy.py/taglimit.py though, so it should hopefully not be
disruptive.
In the earlier custom study changes, we didn't get around to addressing
issue #1136. Now instead of trying to determine the maximum increase
to allow (which doesn't work correctly with nested decks), we just
present the total available to the user again, and let them decide. There's
plenty of room for improvement here still, but further work here might
be better done once we look into decoupling deck limits from deck presets.
Tags and available cards are fetched prior to showing the dialog now,

This has us currently storing an uncompressed and compressed copy of

this takes a close and reopen from about 0.55s to about 0.07s. The old
backup code for comparison: about 0.35s for compression off, about
8.5s for zip compression.

init_backend() accepts a Logger rather than a log file, to allow other

In the future we may want to explore using the tracing crate as an

* Join last backup thread before starting new one
Also refactor.
* Disable auto sync and backup when restoring again
* Force backup on full download
* Include the reason why a media file import failed, and the file path
- Introduce a FileIoError that contains a string representation of
the underlying I/O error, and an associated path. There are a few
places in the code where we're currently manually including the filename
in a custom error message, and this is a step towards a more consistent
approach (but we may be better served with a more general approach in
the future similar to Anyhow's .context())
- Move the error message into importing.ftl, as it's a bit neater
when error messages live in the same file as the rest of the messages
associated with some functionality.
* Fix importing of media files
* Minor wording tweaks
* Save an allocation
I18n strings with replacements are already strings, so we can skip the
extra allocation. Not that it matters here at all.
* Terminate import if file missing from archive
If a third-party tool is creating invalid archives, the user should know
about it. This should be rare, so I did not attempt to make it
translatable.
* Skip multithreaded compression on small collections

Protobuf 3.15 introduced support for marking scalar fields like
uint32 as optional, and all of our tooling appears to support it
now. This allows us to use simple optional/null checks in our Rust/
TypeScript code, without having to resort to an inner message.
I had to apply a minor patch to protobufjs to get this working with
the json-module output; this has also been submitted upstream:
https://github.com/protobufjs/protobuf.js/pull/1693
I've modified CardStatsResponse as an example of the new syntax.
One thing to note: while the Rust and TypeScript bindings use optional/
null fields, as that is the norm in those languages, Google's Python
bindings are not very Pythonic. Referencing an optional field that is
missing will yield the default value, and a separate HasField() call
is required, eg:
```
>>> from anki.stats_pb2 import CardStatsResponse as R
... msg = R.FromString(b"")
... print(msg.first_review)
... print(msg.HasField("first_review"))
0
False
```
Tokio has had to be pinned, because the 1.17 release introduces
a dependency on windows_sys, which fails to build on Windows on
Bazel.
The issue appears to be the build script of a subcrate - it is using
CARGO_MANIFEST_DIR to update the linking path so windows.lib can be
found (it's contained in that crate), but the path is set incorrectly.
dfc25285a2/crates/targets/x86_64_msvc/build.rs
One way we might be able to work around it is to add to the link path
in our own build script.
The previous change in 1871b57663 failed
to consider the browser refreshing case, as reported here:
https://forums.ankiweb.net/t/anki-2-1-50-beta-3-4/17501/30
I previously attempted to solve this by having SetFlag skip the queue
rebuild, then mutating the captured mtimes in the queues. That didn't
work correctly when undoing, as the queue mutations weren't recorded.
This approach combines that attempt and the previous change: flag
setting is an undoable operation again, but does not change the card's
modification time, so it can be applied/undone without a queue build
being required. Instead of special-casing flag changes in the review
screen, we now just redraw the flag on changes.card, as any other card
op will have triggered a queue rebuild.
* Replace Card.data with .original_position
* Use and update original position in v3
* Show original position in card info
* Revert restoring original position for now
* Fix pb card to/from pylib card
* Try original_position as the last pb field
* minor wording tweaks (dae)
This is not ideal, but I struggled to come up with a better solution.
Background:
- The scheduler records the mtime of cards as it's building the queues,
and will throw an error in get_queued_cards() if the card on the DB
has a different mtime. This is to catch bugs - any operation that modifies
cards should be triggering a queue rebuild, or should adjust the queues
appropriately.
- The review screen skips the usual queue rebuild redraw, and directly
updates the flag icon. This is because a rebuild could cause a different
card to appear, or the answer side to switch back to the question side,
neither of which the user expects when they flag a card.
The current behaviour was broken: the queue rebuilding was still happening
on the backend, and the frontend was just failing to reflect it.
I initially tried to special-case Op::SetFlag, having it skip the queue
rebuild, and having set_card_flag() update the mtimes in the active
queue. But those mutations weren't captured by the undo log, so they
didn't get undone when undoing the set flag operation. We could perhaps
work around it by adding a separate undo entry to capture the mutation,
but it started to feel like it would be a pain to maintain moving forward.
By skipping the undo queue and retaining the same mtime, no queue
rebuild is required. Because we're setting usn, the cards will still
sync, but as mtime is not bumped, in the case of a conflict, an older
unsynced change from another client may revert the flag change.

This brings the behaviour a bit closer to the default ordering of new
cards when they are reset, and is better than an undefined template
order. But it's a stopgap solution, and in the long run, filtered decks
need a bit of a rethink with the improved ordering than v3 has brought.
This was broken by an SQLite upgrade - previously we received the rows
in ix_cards_sched order, but recent versions use a table scan for that
query when the order is unspecified. Solved by being explicit about the
order we expect results to arrive.

Python's regex engine performs pathologically on regexes like
'<!--.*?-->' when fed a large string of repeating '<!--' clauses.
Thanks to JaimeSlome / security@huntr.dev for the report; closes#1380.
Solved by switching to the Rust implementation, which does not suffer
from this issue.
entsToText(), minimizeHTML(), and the old regex constants have been
removed; they do not appear to be used by any add-ons.
The 'avoid showing learning card twice' logic is now only applied
when the next learning card was already due to be shown. This'll mean
there will be cases where a learning card does get shown twice near
the end, but it makes the behaviour easier to reason about, for both
us and end users.
Matches should arrive in alphabetical order. Currently results are not
capped (JS should be able to handle ~1k tags without too much hassle),
and no reordering based on match location is done. Matches are substring
based, and multiple can be provided, eg "foo::bar" will match
"foof::baz::abbar".
This is not hooked up properly on the frontend at the moment -
updateSuggestions() seems to be missing the most recently typed character,
and is not updating the list of completions half the time.
There were a few issues going on here:
- If some operation had invalidated the queues, they were subsequently
recreated with a call to .get_queues() in the undo handling code. This
could happen after the changes to the card had already been reverted,
leading to a queue state that didn't match our expectations.
- More generally, it's not safe to assume our mutations will apply
cleanly after the queue has been rebuilt. The next card will vary
depending on the number of remaining cards when interspersing cards of
different types, and a queue-invalidating operation will have changed
the learning cutoff.
So rather than rebuilding the queues on demand, we now check that they
already exist, and were created at the time we expect. If not, we
invalidate them and skip applying the mutations, and a subsequent
refresh of the UI should rebuild the queues correctly.
As part of this change, the cutoff snapshot has been moved into the
normal answer update object.
One possible downside here is that adding a note during review may cause
a newly due learning card to appear when undoing a different review.
If this proves to be a problem, we could potentially note down the
learning cutoff and apply it when queues are rebuilt later.
Context: https://forums.ankiweb.net/t/more-cards-today-question-about-v3/12400/10
Previously, interday learning cards and reviews were gathered at the
same time in v3, with the review limit being applied to both of them. The
order cards were gathered in would change the ratio of gathered learning
cards and reviews, but as they were displayed together in a single count,
a changing ratio was not apparent, and no special handling was required
by the deck tree code.
Showing interday learning cards in the learning count, while still
applying a review limit to them, makes things more complicated, as
a changing ratio will result in different counts. The deck tree code
is not able to know which order cards will appear in, so without changes,
we would have had a situation where the deck list may show different counts
to those seen when clicking on a deck.
One way to solve this would have been to introduce a separate limit for
interday learning cards. But this would have meant users needed to
juggle two different limits, instead of having a single one that controls
total number of (non-intraday) cards shown.
Instead, the scheduler now fetches interday cards prior to reviews -
the rationale for that order is that learning cards tend to be more
fragile/urgent than reviews. The option to show learning cards
before/after/mixed with reviews still exists, but it applies only after
cards have been capped to the daily limit.
To ensure the deck tree code matches the counts the scheduler gives,
it too applies limits to interday learning cards first, and reviews
afterwards.
In the old HTML editor, filenames were % escaped before feeding them to
beautifulsoup, causing bare ampersands to be left alone. The new HTML
editor reads content from the DOM, where a bare ampersand has been
transformed into an &, and that gets saved back into the field,
so the media check now needs to deal with it for images as well.

Interday learning cards are now counted in the learning count again,
and are no longer subject to the daily review limit.
The thinking behind the original change was that interday learning cards
are scheduled more like reviews, and counting them in the review count
would allow the learning count to focus on intraday learning - the red
number reflecting the fact that they are the most fragile memories. And
counting them together made it practical to apply the review limit
to both at once.
Since the release, there have been a number of users expecting to see
interday learning cards included in the learning count (the latest being
https://forums.ankiweb.net/t/feedback-and-a-feature-adjustment-request-for-2-1-45/12308),
and a good argument can be made for that too - they are, after all, listed
in the learning steps, and do tend to be harder than reviews. Short of
introducing another count to keep track of interday and intraday learning
separately, moving back to the old behaviour seems like the best move.
This also means it is not really practical to apply the review limit to
interday learning cards anymore, as the limit would be split between two
different numbers, and how much each number is capped would depend on
the order cards are introduced. The scheduler could figure this out, but
the deck list code does not know card order, and would need significant
changes to be able to produce numbers that matched the scheduler. And
even if we ignore implementation complexities, I think it would be more
difficult for users to reason about - the influence of the review limit
on new cards is confusing enough as it is.
The v3 scheduler will delay the final card from being shown twice in
a row, but the overdue case was being treated the same as the no-learning
case, leading to the message being hidden.
Previously we would just use 250% ease for any new card that had no
pre-configured ease, but this will result in decks that have
non-standard ease values to have "set due date" cards in them that don't
match. In order to make this somewhat more efficient, we cache
deckid->ease lookups during this operation.

Unfortunately a popular note taking tool has been misusing cloze
markers in its deck exports. We may want to add this back in the
future, but we'll probably want to start by warning users, to give
people time to adjust.
