Added a unit test for changing app and wallet DBs passwords.
Refactored geth_backend to simplify and allow wallet db password changing.
Fixed opening database with wrong password.
Some functions split to be more cohesive, custom PostSteps are
stored as pointers to allow their retrieval and parameters passing
in runtime if needed (some extra work is dropped and TBD
when needed)
The only place where appDB is used in wallet is activity,
which refers to `keycards_accounts` table. So a temporary
table `keycards_accounts` is created in wallet db and updated
before each activity query.
Main changes:
- Refactor activity API to propagate token identities.
- Extend service to convert token identities to symbols for filtering
multi-transaction
- Filter transfers, pending_transactions and multi-transactions based
on the provided token identities
- Return involved token identities in activity API
- Test token filtering
Also:
- Fixed calling cancel on a filer activity completed task to release
resources
Notes:
- Found limitations with the token identity which complicates things
by not allowing to filter by token groups (like token-code does)
Updates status-desktop #11025
Improve the error management in order to avoid DB corruption in case the process is killed while encrypting the DB.
Changes:
Use sqlcipher_export instead of rekey to change the DB password. The advantage is that sqlcipher_export will operate on a new DB file and we don't need to modify the current account unless the export is successful.
Keeping the rekey requires to create a DB copy before trying to re-encrypt the DB, but the DB copy is risky in case the DB file changes wile the copy is in progress. It could also lead to DB corruption.
* perf(sqlCipher): Increase cipher page size to 8192
Increasing the cipher page size to 8192 requires DB re-encryption. The process is as follows:
//Login to v3 DB
PRAGMA key = 'key';
PRAGMA cipher_page_size = 1024"; // old Page size
PRAGMA cipher_hmac_algorithm = HMAC_SHA1";
PRAGMA cipher_kdf_algorithm = PBKDF2_HMAC_SHA1";
PRAGMA kdf_iter = kdfIterationsNumber";
//Create V4 DB with increased page size
ATTACH DATABASE 'newdb.db' AS newdb KEY 'key';
PRAGMA newdb.cipher_page_size = 8192; // new Page size
PRAGMA newdb.cipher_hmac_algorithm = HMAC_SHA1"; // same as in v3
PRAGMA newdb.cipher_kdf_algorithm = PBKDF2_HMAC_SHA1"; // same as in v3
PRAGMA newdb.kdf_iter = kdfIterationsNumber"; // same as in v3
SELECT sqlcipher_export('newdb');
DETACH DATABASE newdb;
//Login to V4 DB
...
Worth noting:
The DB migration will happen on the first successful login.
The new DB version will have a different name to be able to distinguish between different DB versions.Versions naming mirrors sqlcipher major version (naming conventions used by sqlcipher), meaning that we're migrating from V3 to V4 DB (even if we're not fully aligned with V4 standards). The DB is not migrated to the v4 standard `SHA512` due to performance reasons. Our custom `SHA1` implementation is fully optimised for perfomance.
* perf(sqlCipher): Fixing failing tests
Update the new DB file format in Delete account, Change password and Decrypt database flows
* perf(SQLCipher): Increase page size - send events to notify when the DB re-encryption starts/ends
Extended the migration process with a generic way of applying custom
migration code on top of the SQL files. The implementation provides
a safer way to run GO code along with the SQL migrations and possibility
of rolling back the changes in case of failure to keep the database
consistent.
This custom GO migration is needed to extract the status from
the JSON blob receipt and store it in transfers table.
Other changes:
- Add NULL DB value tracking to JSONBlob helper
- Index status column on transfers table
- Remove unnecessary panic calls
- Move log_parser to wallet's common package and use to extract token
identity from the logs
Notes:
- there is already an index on transfers table, sqlite creates one for
each unique constraint therefore add only status to a new index
- the planned refactoring and improvements to the database have been
postponed due to time constraints. Got the time to migrate the data
though, extracting it can be done later for a more efficient
implementation
