This patch improves our backup functionality in a number of ways:
- Only backup the vault when important changes are made, not when the order of
entries is changed, for instance.
- Don't bubble up backup errors when saving the vault.
- Instead, show an error bar in the main view if the most recent backup attempt
failed.

Clicking on the error bar will take the user to the backup settings.
This'll display a warning to users who don't have automatic time synchronization
enabled on their device. Aegis will try to take the user to the right settings
menu if they tap "Yes". Users also have the option to silence the warning.

The main goals of this patch are to:
- Improve the exception handling in Aegis and the way we present errors messages
to the user when they occur.
- Write exception stack traces to the log in more places, so that the ADB logs
we ask for from our users when reporting bugs become more useful.
- Reduce the amount of times we throw a RuntimeException, particularly when an
Android Keystore operation fails.
Achieving the above goals ended up resulting in a very large refactor. The
intro and unlock flow of the app need to be retested entirely.
This makes it so that EditEntryActivity directly saves entries to the vault,
instead of passing them back to MainActivity through an Intent first. This
prevents crashes that can occur when an entry has a large icon and the Bundle
inside the Intent becomes too large.
This is the first part of a series of patches I plan on submitting, where I try
to repair the damage done by my misguided obsession of only touching the global
state in certain places.
We decided on calling the state file the "vault" a while back. This patch makes
the naming consistent across the codebase. I left "DatabaseImporter" classes
alone, because I'm not sure what a better name for those would be.
This adds an option to highlight tapped entries, so that it's easier to
distinguisch between the one you're trying to enter into a website and the other
ones.
Only one entry can be highlighted at a time. Perhaps it would make sense to
change our tap to reveal functionality to behave the same, so that the two
features are nicely in sync. I can address that in a separate PR if we decide to
do so.
This also fixes an issue with the use of the Iconics library where it was
initialized twice. I also removed the dependency to [AndroidX Preference
eXtended](https://github.com/takisoft/preferencex-android), as there don't seem
to be any issues with using the vanilla AndroidX preference library anymore.
This patch introduces the new ``UUIDMap`` type, reducing code duplication and
making UUID lookups faster. We currently already use UUIDs as the identifier for
the ``DatabaseEntry`` and ``Slot`` types, but the way lookups by UUID work are
kind of ugly, as we simply iterate over the list until we find a match. As we're
probably going to have more types like this soon (groups and icons, for
example), I figured it'd be good to abstract this away into a separate type and
make it a map instead of a list.
The only thing that has gotten slower is the ``swap`` method. The internal
``LinkedHashMap`` retains insertion order with a linked list, but does not know
about the position of the values, so we basically have to copy the entire map to
simply swap two values. I don't think it's too big of a deal, because swap
operations still take less than a millisecond even with large vaults, but
suggestions for improving this are welcome.
I had to update gradle and JUnit to be able to use the new ``assertThrows``
assertion method, so this patch includes that as well.
We were leaking some resources by not unregistering listeners when destroying
the entry list view. The code refresh loop of the leaked view started running in
a tight infinite loop, which causes a lot of lag in the main activity.
Commit afb9e59711 fixed a bug where the password
encode function would add null bytes to the end of the output. Luckily (I
thought), PBKDF2 produces collisions for inputs with trailing null bytes and
thus scrypt does this as well, so we could safely change that function to remove
the null bytes without any impact. Unfortunately, that doesn't hold up if the
password is over 64 bytes in size. So after that change, the KDF started
producing different keys than before for such passwords and thus some users
could no longer unlock their vault.
This patch addresses the issue by using the old password encode function for
passwords over 64 bytes and repairing the affected password slot.
This fixes the following bugs:
- Sort category is forgotten after lock/unlock
- The sort mode is not respected for new entries
I got a little carried away while working on this patch and also included the
following other enhancements:
- Simplify the SortCategory, Theme and ViewMode enums
- Simplify usage of string resources
- Don't call notifyDataSetChanged and runLayoutAnimation unnecessarily
Move onScroll to seperate class to avoid duplicate code
Move importing logic back to the PreferencesFragment
Add minor changes
Add ImportEntry to properly track checked states
Minor layout changes
