Due to a number of hacks, the style guide can be used to show Backbone
views. This will allow a smooth path from the old way of doing things to
the new.
Class: `ConversationController`.
This function should not be used in application code as it creates potentially
invalid `Conversation` instances in our global conversation collection. We keep
making it available for testing purposes.
Using 2 hex characters [0-9a-f] will give us 16 * 16 = 256 root folders which
seems more manageable than 4096 (16^3). Assuming a user has 10,000 attachments,
they should roughly distribute at ~40 per folder with prefix length 2 rather
than ~2.5 per folder with a prefix of 3.
Using hashes, we get the benefit of deduplication but if a user receives two
messages with the same attachment, deleting one would delete it for both since
they are only stored once. To avoid the complexity of tracking number of
references, we simply generate random file names similar to iMessage on MacOS
(?) and Signal Android.
Backup creates, in a target directory:
- An attachments folder, with all attachments, each named for their
parent message's id - a GUID. If there is more than one attachment
in a given message, each attachment beyond the first will end with
'-N', zero-indexed.
- A file named messages.zip. It contains exactly what went to disk in
the original export code, but zipped up.
Export is now only 'light,' and in this new messages.zip format.
Import supports both the new format and the old format. If the target
directory has a messages.zip file, we'll treat it as the new format.
Next up: Encrypting attachments and the messages.zip!
Allows errors to be formatted and sanitized for logging. Removes sensitive paths
such as the app root directory.
Ideally, this module would be called singular `Error` but that is already a
global name. Using `Errors` plural is similar to Java convention for utilities
such as `Arrays`, `Collections`, `Files`, etc. See:

This makes it more consistent with ‘Report an issue’ under View > Debug Log.
Not using ellipsis as menu item doesn’t require user confirmation:
