Due to an Android P bug, we basically need to stop calling
startService() in onResume()/onPause(). That means I had to turn
MessageRetrieval service into a singlton instead of a service. I also
moved the offending KeyCachingService calls into static methods that
didn't have to start the service.
If we already have two active processing GCM messages, there's no
benefit to a third. In fact, enqueuing additional ones will likely only
end up showing the foreground notification unnecessariliy.
Previously we were starting a background service, which isn't allowed
for targetSdk 26. This will do the same thing but at a time decided by
the system.
This gives us more control over when it happens, as well as lets us set
things like the debug level. Also let's us get rid of the synchronized
block we had in Application#onCreate().
This sound isn't supposed to play when you have notification sound off,
but apparently some Huawei phones will play it anyway. Until we can
figure out a better way to handle it, we're just removing it.
We don't store non-user-selected colors in the database. That means that
when we update the palette, we still have to hash based off of the legacy
palette when generating a color if we want to migrate to a
similar-looking color.
Unfortunately, because the new palette is smaller, some colors are
"overloaded", meaning that when we hash based off of the legacy palette,
some colors will be more/less common than others. To fix this, we simply
persist all current colors in the database, then switch our hashing list
to what we really want.
Occasionally a job may be run when the app is in a network-restricted
mode, like a form of doze. When this happens, jobs can timeout due to
lack of network access, causing a cascade of job delays. This is
particularly bad in the case of message retrieval.
To prevent this, if a job that normally requires network detects that no
network is available when running, then we start a foreground
notification.
Some devices will randomly throw RuntimeExceptions here due to hardware
issues. We were already doing broader catch statement in CameraView, so
I moved it here as well.
Unfortunately, while there does exist an XML property to disable the
indentation, it's bugged for category headings, so we have to do this
silly thing where we strip the padding in the adapter. Hopefully they'll
fix the bug and we can move to use the sanctioned property.

On older versions of Android, TextureView#getBitmap() needs to be called
on the main thread. On mid range phones, this is ~50ms. Normally that'd
be bad, but the UI isn't doing anything at that point anyway.
Fixes#8232
We were being inconsistent in how we were handling exiting multiselect,
and it wasn't behaving properly when you left by clicking the 'x'. Now
it's all handled centrally.
Fixes#8234
A new, fullscreen camera capture flow that easily allows you to capture
and edit a photo before sending it. Replaces the current half-screen
camera button.
Keep the single-use behavior, but allow the creation of multi-use memory
blobs that can be deleted when we're done with them. Will help out with
having URI's for temporary images during the camera capture flow.
This also fixes the situation where we block group-leave messages,
preventing blocked contacts from leaving groups.
Fixes#7970
Also, this forced us to upgrade libsignal-service, which fixes the
websocket timeout issues. Thanks to @dpapavas!
Fixes#6644
Forwarding of shared contacts currently just creates an empty draft.
You can't preview a shared contact before you send, which would make the
forwarding flow inconsistent across media types. So it's easier to just
hide it for now.
Fixes#8195
This could cause us to think push messages were actually sent with
a SIM. We also now prevent rendering SIM info on push messages in
the conversation view.
Fixes#8176
We were hitting the transaction limit size. This change scales down
shortcut icons to be at most 300x300, which comes out to ~360kb, which
should be safely under the limit of 1mb.
Fixes#8139
We were getting an IllegalArgumentException during channel creation on
some Samsung phones. Stack trace didn't give me much more than that, so
just adding in some additional safeguards that make sense based on
reading AOSP.
We manually play the ringtone when in-thread notifications are enabled,
but we weren't using the sound specified by the channel in the system
settings. This fixes that problem by reading the NotificationChannel
setting.
We were getting a TransactionTooLargeException when giving an
EditText a very large (1.5MB+) text block. This has been resolved
by switching to a RecyclerView to show the text line-by-line. As a
side-effect, this improves scroll performance on lower-end devices.
Also, I added a button to jump to the bottom of the log because I
really wanted one :)
Fixes#8124
Previously, we were making a new copy of the entire source string after
every scrubbed substitution. In the case of our new, larger log files,
this was very slow. It's been changed so we only ever create one new
copy.
In practice, on a Moto E (2014), scrubbing a 1.5MB log went from
>4000ms to ~100ms.
When using notification channels, us setting priority actually has
no effect. So instead of having a non-functional setting, we've
routed the notification priority setting to go to the system
notification channel settings page for our Messages channel.
Address linkification on Android is pretty busted, and the docs
acknowledge it (see Linkify#MAP_ADDRESSES). Safest thing to do
at the moment is remove it. Looks like we may be able to get
better address linkification on API >= 28, but adding it will
be more involved.
Fixes#7730
Previously, we'd only show the attachment button when the user had
yet to enter any text. To add an attachment after text was entered,
you'd have to go to the three-dot menu. Now we just show a little
attach button in the text area.
I also took the opportunity to clean up other button paddings and
stuff in the compose area so things look better and react to text
sizes more predictably.
Added a new logger that persists logs for a longer duration to the
user's cache directory. Logs are encrypted. The new logs are sent
in addition to the user's logcat output.
For short messages in a cluster, the contact photo was sometimes taller
than the actual bubble, leading to extra weird space. So instead we use
a container to hold the width of the cell, and set the avatar to be GONE
instead of INVISIBLE.
The previous way we were getting the next/previous record didn't take into
consideration that some records aren't in the cursor -- some are in the
fastRecords map. We now use the proper position to get the next/previous
message.
Apparently onAnimationEnd is not a reliable event on some Android
versions, so I've moved to instead using a simple postDelayed() that is
the same length as the animation.
The media size traditionally determines the bubble size, but the author
could make it wider, which would lead to rendering issues. In the case
of media attachments (images, videos, and shared contacts), we restrict
the width of the author name. When there's a number+profile name combo,
we split the space 50/50 between the two.
In particular, there were many issues with drawing corners.
Unfortunately, there's no pretty way to get masking working on every
Android version, so we have to switch back to using custom backgrounds
and then using multiple masking methods depending on Android version.
Also, I had to remove attr references in drawables. They crash on 4.x.
Unfortunately, there's apps out there that trigger contact changes
very frequently. Because we listen to the system for contact
changes to tell us when to sync, that could result in us sending
an abundance of contact syncs to linked desktop instances.
This throttles contact sync requests using the following methodology:
- By default, throttle contact syncs to 6 hrs while the app is
backgrounded.
- If a sync is throttled in the background, we set a dirty flag and
will execute the sync the next time the app is foregrounded.
- Syncs explicitly requested by desktop are never throttled.
The directory we were previously saving backups to on the external SD
card is actually deleted upon app uninstall and/or clearing the app's
data. There's also no reliable way to write to the root of an external
SD card (that isn't comically inconvenient), so for now it's safer if we
just move back to getting the regular 'ol standard external storage
directory (which is likely internal storage, despite its name).
Fixes#7845
For self-sends, we were never marking attachments as uploaded. I made is
so that happens now, but to prevent it for showing for already-sent
messages, we also don't show controls for self-send conversations.
This particularly helps with the bug where people who were newly added
to a group wouldn't receive an expiration timer until the first message
was sent.
Previously, contact shares would be displayed as "Media Message". Now
it'll show the same as it does in a notification, namely
"{contact-emoji} {contact-name}".
Previously, we were running this job in PushSendJob#onCanceled().
However, with the new retry logic, this won't happen for 24 hours.
Instead, we now schedule the job in PushSendJob#onRetry().
Previously, we retried based on a count. Now we've added the ability to
keep retrying for a specified time, using exponential backoff to
throttle attempts.
We never properly registered the ExpirationListener, meaning we were
relying on the wait-notify loop of ExpirationManager to delete things.
This normally works, but fails when your phone goes to sleep. So I
properly registered the receiver, and then added a failsafe to re-run
the ExpirationManager if we're about to render an expired message.
Fixes#7906
We have to make some changes, and it's gotten to the point where
maintaining it as a separate library is more hassle than it's worth,
especially with Google releasing WorkManager as the preferred job
scheduling library.
Previously, because apostrophes were 'banned' characters, searching for
them wouldn't work. That meant you couldn't find words like "I'm". Now
we just replace the apostrophe with a space and things "just work"
because of the nature of SQLite tokenization and prefix queries.
Previously, we didn't support highlighting search results that had
tokens in the middle of the matches, which is a possibility with FTS.
Now we do more robust highlighting, as well as highlight matches in
phone numbers.
Previously, we made each full-text search query a single prefix query.
That means that the query "do c" would turn into "do c*". That means it
would match "do cat" but not "dog cat".
Now, we make each token a prefix query. So "do c" would turn into
"do* c*". That means it would match both "do cat" and "dog cat".
Previously, if a message disappeared while looking at it in the search
results, it'd still stick around. Now they'll disappear from the results
in real-time.
1) There was an issue where we wouldn't auto-download group syncs.
2) There was another issue where we didn't show the download controls
for messages you sent yourself.
Fixed#7920
There was an issue where we were backing up group receipts and attachments
that were for expiring messages (which are already excluded from the backup).
This commit excludes these items from the backup, and for backups made
before this change, this commit also deletes these invalid entries at
the end of the restore process.
We also do a little database migration to cleanup any bad state that may
have been imported in the past.
Turns out that there's some weird quasi-state when you come out of
airplane mode, that if you do an InetAdress lookup, it returns some
weird IPv6-looking garbage address. Going to retry in that scenario
instead of assuming an outage.
Previously, if an operation failed, we set the result to "null".
However, this was a mistake. Setting the result at all assumes success.
Instead, we need to set an exception so the ListenableFuture knows that
the operation failed.
A variety of improvements to the image editor, such as:
- New, fullscreen styling
- Smoother lines
- Better text and sticker handling
- Improved color picker with a history pallette
- New highlighter tool
Previously, SQLCipher's memory usage would grow indefinitely, up until
it hit the end of the cursor. We've now switched to a release where the
memory used by the cursor can be bounded.
If a user is upgrading to use the SQLCipher database (which happened
back in 4.16, so this only applies to relatively dormant users who are
just getting back into the app) and received a new "user X joind signal"
message, then it could screw up the migration. So we're just dropping
these notifications that happen in this narrow window.
The sticky header cache was keeping views across rotations, causing them
to render incorrectly afterwards. I added a method to invalidate the
header layouts after rotation.
Fixes#7890.
First, FTS index contents do not need to be exported. They will be recreated naturally.
Second, we can't export the secret FTS tables, or SQLite will think it's corrupted.
Fixed an issue where jumbomoji were not properly being rendered
when using system emoji. Also fixed an issue where the text
content wasn't properly being recalculated when the view is
resized.
Fixes#7875
1. Switch to using default text rendering if there's no emoji present in
the string.
2. Reduce redudant redraws by skipping of setText() calls for identical
strings.
Together, these two changes should reduce the vast majority of
flickering we see with EmojiTextView ellipsizing.
I think I was initially lured into searching by rank because it gives
the illusion of providing the "best match". However, in practice, FTS
never gives back "bad" matches with low ranks -- all of the results it
returns will contain your query in some form (most commonly a direct
substring, but they do take some liberties if you have multiple tokens
in your queries). Given that, in general, more recent search results are
in fact more relevant, we can sort by date exclusively and get a better
ordering overall.
If a search result snippet spans two lines, we only show the first line.
For the purpose of display, we first remove all newlines in order to
make the full snippet visible.
Previously, we'd always use the recipient of the message record, which
was incorrect for messages sent to groups. Now we always use the
recipient for the matching thread record.
Fixes#7823
Glide will use the dimensions of the target ImageView as the dimensions
for the image it's loading. This caused problems in the case of
ThumbnailView, as we were constantly changing the ImageView dimensions,
meaning Glide may not have the most recent values (it may be called in
between measure calls, for instance).
To solve this, we now will always override the default image dimensions
when we load an image. If no dimensions are present, we will default to
the layout_width and layout_height of the ThumbnailView.
Fixes#7810
Notifications for replies will no longer display as a "Media Message" if
they do not contain media. Instead, they will just contain the reply
text.
Fixes#7798
Sending shared contacts isn't backwards-compatible, so we want to have a
few releases where receiving is enabled, but not sending. That way, when
we enable sending, most users should be able to properly receive the
shared contact messages.
When you share a vCard from an external app (like the Contacts app) into
Signal, we'll now convert it to a pretty Shared Contact message and
allow you to choose which fields of the contact you wish to send.
The "contact" option in the attachments tray now brings you through an
optimized contact sharing flow, allowing you to select specific fields
to share. The contact is then presented as a special message type,
allowing you to interact with the card to add the contact to your system
contacts, invite them to signal, initiate a signal message, etc.
There's a chance that the AsyncTask that retrieves a quoted message's
position could finish after the fragment is detached, which would cause
a crash. I've changed it so if this case occurs, the result is ignored.
Also, I noticed that when searching the message table, if a quote can't
be found, we'd end up traversing the entire table. To prevent this from
taking forever on large message tables, I've limited it to searchin only
what is currently present in the adapter.
Fixes#7756
Did a refactor to better organize the camera flipping code. Also, I
wanted to make sure we handle the cases where the user doesn't have two
cameras (or no cameras, for that matter). In these cases, we just don't
show the appropriate buttons.
Previously, quotes were not saved to drafts, meaning they would be lost
when leaving the conversation or app. Now, a QuoteId (which represents
the necessary data to restore the QuoteModel) is serialized and stored
in the DraftDatabase.
Fixes#7716Closes#7729
Unfortunately, the change wasn't as simple as just switching to use our
EmojiTextView. That view only supported single-line text. I added
support for multi-line text.
Fixes#7704.
We now check if _any_ text is selected when doing a batch selection
to determine if we should show the copy option. Also, previously it
was putting in empty lines for messages that don't have any text. I
changed it so empty messages have no effect on the text that is copied.
Fixes#7472
Currently, if you're searching for a contact to start a conversation
with or send a share to (via the Android sharing system), groups do not
appear. With this change, groups will now appear when searching, located
under their own heading.
Fixes#7202.
Closes#7577
Previously, we were always rendering images as squares. Instead of doing
that, we now render them as close to true-to-size as possible (within
reasonable min/max width/height boundaries).
Strip all EXIF metadata from all JPEGs by re-encoding the JPEG. This
will keep all of the necessary visual effects of the tags (by encoding
them directly in the image data) while stripped the EXIF tags
themselves.
It is now possible to batch-delete media in the "media overview" screen.
You can long press to enter multi-select mode. Then a delete button
appears on the menu bar. After pressing delete, you will get a
confirmation, and if the user confirms, the items will delete while a
progres dialog shows.
When viewing a media in the media preview, you can delete it by pressing
a delete button on the action bar. It will then ask you to confirm your
choice. If you confirm, it will delete the attachment from the database
and from disk. If it was the only attachment for that message, the
message itself will also be deleted.
In a number of locations in the code, there were conversions of message
expiration times from seconds to milliseconds, and then assigned to `long`
contexts. However these conversions were being done as integer multiplication
rather than long multiplication, meaning that there was a potential for
overflows.
Specifically, the maximum value that could be represented before overflowing
was (2^31 / 1000 / 60 / 60 / 24) days = 24.8 days (< 1 month). Luckily the
current allowed timeouts are all less than that value, but this fix would
remove the artificial restriction, effectively allowing values of 1000x greater
(68 years), at least for android.

1) Move contact URI, contact photo URI, and custom label
into recipient database, so there are no longer any
contact DB queries during Recipient object loading.
2) Use a SoftHashMap so that any referenced Recipient objects
can't get kicked out of the cache.
3) Don't load Recipient objects through the provider during sync.
This was a super expensive thing to do, and blew up the cache.
4) Only apply changes to Recipient objects during sync if they
are in the cache. Otherwise, there should be no outstanding
references, and the changes are fine going exclusively to
the DB.
The whole recipient pipeline needs to be changed more subsantially,
particularly given the way directory discovery works with it. This
will temporarily solve the problem though.
1) The "obsolete" images like "swimmer" need to alias to
"man_swimming" so that they can be rendered correctly.
2) There are a whole bunch of emoji-data elements
(like white_frowning_face) that have "unified" code points which
have changed to include a "terminator."
