"Android Not Responding" background freeze

[adbenitez]

I disabled all my other profiles and left only the problematic profile enabled (in arcanechat I have control over start_io per profile) and collected the following log, in the log from the start it was all slow and getting "Android Not Responding" due to some background thread while I could use the app despite some operations like long-pressing a message and reacting being very slow due to getChatMsgs()

the ANR dialog would keep appearing over and over so some background thread got permanently blocked calling some core operation/api, I was trying to react to a message and remove reaction while the app was kinda frozen and very unresponsive with the ANR poping up until eventually it did my actions

core-only log:

At least getChatlist() here is 331ms, 93ms, 208ms, 60ms and 192ms, so it is not related to #7848

[adbenitez]

knowing the last log line before ANR was useful.

@link2xt just did a test for this again, and this was the last lines core-wise at the bottom of my log when the dialog appeared:

also when the ANR dialog appears, it has a "more info" button that provides useful logs, here is the report:

Error in ArcaneChat 5dab608edfa2.txt

according to this the freeze was in the call to the native method com.b44t.messenger.DcChat.getProfileImage when I clicked a chat to open it, the core was already stuck so that call got frozen

[link2xt]

getChatMsgs for one of the chats appears to be slow:

getChatMsgs(71): 7ms
getChatMsgs(71): 2ms
getChatMsgs(71): 1ms
getChatMsgs(71): 6ms
getChatMsgs(53): 1959ms
getChatMsgs(53): 73ms
getChatMsgs(53): 3124ms
getChatMsgs(53): 2554ms
getChatMsgs(53): 2013ms

Could be simply a large number of messages, the only query inside is properly indexed:

sqlite> EXPLAIN QUERY PLAN SELECT m.id AS id, m.timestamp AS timestamp
               FROM msgs m
              WHERE m.chat_id=?
                AND m.hidden=0;
QUERY PLAN
`--SEARCH m USING INDEX msgs_index2 (chat_id=?)

[adbenitez]

Could be simply a large number of messages

that chat is the mastodon notifications chat, which yeah likely has quite some messages but I think also you and others have that chat

[r10s]

to be clear, after discussing with @adbenitez , the issue does not happen when the device is offline

[adbenitez]

some more logs:

here the account was in "updating..." for quite a while, I suspect there is a bug in the "leave and delete chat" logic and I am still part of channels I left and get spammed with messages you can't decrypt but still slow you down trying to decrypt?
Already saw another of my profiles still in a channel I had previously left.

log.txt

this one is a full small session from start to end, just opened some chats and back and got ANRs (each ANR appears in the log as "Wrote stack traces to tombstoned"):

and here is another Stack Trace of the ANR provided by the system:

I suspect there is a bug in the "leave and delete chat" logic and I am still part of channels I left and get spammed with messages you can't decrypt but still slow you down trying to decrypt

There are lines like this in the log:

2026-08-04 10:02:30.077 26861-26879 DeltaChat com.github.arcanechat W [accId=3] src/mimeparser.rs:398: decryption failed: decrypt_session_key_symmetrically: Query returned no rows

Maybe we should limit the number of keys tried from broadcast_secrets.

Does the log say how many rows broadcast_secrets table has?

[adbenitez]

Does the log say how many rows broadcast_secrets table has?

this is not part of the log report it seems, did a normal backup to check: 28 rows only

[adbenitez]

but the ANR also happens while there is not that decryption errors so I doubt it is the cause

[adbenitez]

for the record, after I did the manual backup (just created the backup but didn't import it) now I have not got any ANR anymore, maybe that did some DB cleanup before exporting but I have no clue if it is just coincidence

[adbenitez]

another fact: previously just trying to stop IO (via enable/disable toggle in ArcaneChat) would take quite some seconds and the whole UI would become very unresponsive, now stop_io is quite fast again and the toggle goes to disabled (IO stopped) almost immediately
