- different approach to vector manipulation - more on the fly operations. Prepared for fully offloaded operations, BP on Trezor with constant memory.
- memory requirements reduced from (4MN + const) to (2MN + const)
- more raw methods to avoid unnecessary encoding/decoding
- chunking improved, chunk size set as a constant, changed from 64 to 32, missing pieces implemented to cover also BP 16
- proof_v8 support discontinued, old hardfork, not needed anymore
- get_exponent register clash fixed (for large vectors)
- reduced heap fragmentation by removing some temporary allocations
- hashing with len and offset to reduce heap fragmentation by creating a sliced arrays
- use to() wherever possible to avoid allocations and return of mutable private object
- global functions start with _ prefix, reduce import footprint
- use __slots__ in classes to minimize footprint
Apart from making the code more correct for its users in
apps.common.confirm and elsewhere, this fixes a problem where the
confirm_signal would be scheduled before the dialog is rendered.
By making sure that handle_rendering is scheduled (i.e., listed in
create_tasks) before confirm_signal, we can be sure to render at least
once and thus appear in the UI test results.
This is to avoid including app-specific functionality in storage and
avoid circular imports. The following policy is now in effect: modules
from `storage` namespace must not import from `apps` namespace.
In most files, the change only involves changing import paths.
A minor refactor was needed in case of webauthn: basic get/set/delete
functionality was left in storage.webauthn, and more advanced logic on
top of it was moved to apps.webauthn.resident_credentials.
A significant refactor was needed for sd_salt, where application (and
UI) logic was tightly coupled with the IO code. This is now separated,
and storage.sd_salt deals exclusively with the IO side, while the app/UI
logic is implemented on top of it in apps.common.sd_salt and
apps.management.sd_protect.
Based on the testing feedback I've made slight modifications to the UI.
Main points:
- running on the full brightness during the process (previously dimmed, felt broken)
- overlaying layout fix after transaction confirmation
