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.
