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
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
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
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
The images for group avatars are stored directly in the datbase, which
is fine since they are small. But then there's no reason to have them
lingering on the filesystem.
Also removed the unused group associatedAttachmentId property.
// FREEBIE
What we *previously* refered to as attachments are actually just the
attachment's id (NSString). This has tripped me up a few too many
times.
Also, use generics with attachment id's array.
// FREEBIE
In theory, this should have already been handled by the
YapDatabaseRelationship extension via edges.
However, in practice, there were situations (cause unknown) where
interactions would exist without an edge to their corresponding thread.
Rather than being clever with the edge/callback machinery, now threads
explicitly delete all their interactions, and interactions delete all
their attachments (when applicable).
Also, a class to clean up spurious interactions / attachments
In the process:
- refactored TSYapDatabaseObject init to specify designated initializer
- added some testing niceties to TSYapDatabaseObject
// FREEBIE
- log errors
- forward declare where possible
- clang-format
- remove inaccurate file headers
- include Pods in Example app build target to get SignalServiceKit warnings
- Fix those warnings!
// FREEBIE
