Motivation
----------
We were often swallowing errors or yielding generic errors when it would
be better to provide specific errors.
We also didn't create an attachment when attachments failed to send,
making it impossible to show the user what was happening with an
in-progress or failed attachment.
Primary Changes
---------------
- Funnel all message sending through MessageSender, and remove message sending
from MessagesManager.
- Record most recent sending error so we can expose it in the UI
- Can resend attachments.
- Update message status for attachments, just like text messages
- Extracted UploadingService from MessagesManager
- Saving attachment stream before uploading gives uniform API for send vs.
resend
- update status for downloading transcript attachments
- TSAttachments have a local id, separate from the server allocated id
This allows us to save the attachment before the allocation request. Which is
is good because:
1. can show feedback to user faster.
2. allows us to show an error when allocation fails.
Code Cleanup
------------
- Replaced a lot of global singleton access with injected dependencies to make
for easier testing.
- Never save group meta messages. Rather than checking before (hopefully) every
save, do it in the save method.
- Don't use callbacks for sync code.
- Handle errors on writing attachment data
- Fix old long broken tests that weren't even running. =(
- Removed dead code
- Use constants vs define
- Port flaky travis fixes from Signal-iOS
// FREEBIE
* Maps numbers to names in TSGroupModel
Use an injected ContactsManager to look up proper user names for phone numbers in [TSGroupModel getInfoStringAboutUpdateTo].
FixesWhisperSystems/Signal-iOS#757
* Supports custom messages for TSOutgoingMessage
This will enable Signal-iOS to push detailed information about TSGroupModel updates through SignalServiceKit and into the TSInfoMessage created by TSMessagesManager+sendMessages
// FREEBIE
Started extracting a MessageSender class from TSMessagesManager+send for
easier testability and in hopes of further slimming down that son of a
gun.
// FREEBIE
In coordination with Desktop and Android, iOS will be using all-numeric
fingerprints, aka "Safety Numbers".
Furthermore, the concept of verifying one identity and then the other
has been removed. Instead we ask users to exchange a single number, or
scan a single QR code. These credentials are built by combining the
users identities.
// FREEBIE
If we have a serialized object in our data store that wasn't properly
removed, we can be faced with an exception when enumerating objects in
the database, e.g. when we add a new Yap Index.
// FREEBIE
This would especially affect users with large databases on older
devices.
Some of these database extensions aren't strictly necessary to launch
the app. Theoretically we could see weird read receipt behavior for
the initial 10-30 seconds after the app is launched for first time.
// FREEBIE
A botched migration 6 months ago left some lingering TSRecipients
serialized in our data store, laying in wait to explode the next time we
enumerate every object in the database (e.g. when we add an index).
// FREEBIE
Initially we don't have device messages for our remote device. We need to send the empty device list to get the updated list of remote devices.
Introduced lots of dependency injection to make MessagesManager more testable.
// FREEBIE
* Don't attempt to send a message unless we've successfully built a deveice-messages
* Only process message exception when we're done with retries.
// FREEBIE
Also, more nullability annotations.
NSURL can't be given a nil filepath. This can occur when a previously
supported attachment was downloaded, and then viewed after that
attachment was no longer supported (e.g. when installing back and forth
across versions)
// FREEBIE
* By providing a view extension for secondary devices we can use that in
a view mapping to power our devices view controller, and avoid any race
conditions with uncommitted transactions.
* Fix crash when you're not in your own contacts
* New device appears on top
* Don't show "edit" button unless there are devices, or rather, the helpers to do so.
* Fix glitchy refresh
Saving unchanged records was causing the tableview to redraw, which was
mostly invisible, except that if the refresh indicator were running, it
would twitch.
// FREEBIE
Ideally we'd be using file streams so we wouldn't have to load it all
into ram but none of the attachment uploading infrastructure takes
streams (yet!)
// FREEBIE
After provisioning a desktop client, you'll see messages sent from your
phone appear on your desktop client, and messages sent from the desktop
client appear on your phone.
* In the process extracted some of the Attachment processing logic out
of the giant MessagesManager.
* Some nullability annotations on affected files.
// FREEBIE
* new protobufs from libsignal-service-java@a1c93edc40e3ce201fa4e70339a3e6f4e197e319
* Makefile to build ObjC classes from *.proto
* refactored some touched code to minimize duplication
* removed unused protos
* deleted some dead code
* renamed method for clarity
// FREEBIE
