Delete messages after N-days locally

[r10s]

counterpart of #1206

for the first approach, IMAP-deletion time must not be longer than local deletion time.

messages in the "saved messages" chat should not be deleted, neither locally nor remotely.

one goal is to create some sort of ephemeral mode, where seized devices do not contain arbitrary old information. keeping N messages per chat as proposed in #1277 and deltachat/deltachat-core#244 would not fulfill these usecase.

NB: N-days is just an example, probably we need some finer resolution.

I'm very surprised by now!

See my last comment related #1277 (comment)

I'm concerned about these thoughts now.

Maybe new requirements should be added but existing one's from core 244 should be implemented finally now. ... before we go into new adventures!
As r10s said in his last comment of #1277: The requirements are waiting since 2018 now!

My recommendation for everyone who's interesting in this or these issues:

Please read full story of deltachat/deltachat-core#244 again to recall all thoughts and arguments in mind.

[csb0730]

IMHO I think this issue should be renamed to "Automatic delete of local messages".

"Deleting after N-days" is only one approach (IMHO a bad one; depends on use case).

thanks for your input, however, this issue tracker is about bugs and feature that are actually implemented by someone - and this is "Delete messages after some time" in this issue. for feature requests and discussions, please use the forum at https://forum.delta.chat

This means that someone is working at this issue here "Delete messages after N-days locally" ?

IMHO then I'm correct here.
My intension is to remark that delete messages after a certain time will purge messages from rarely used chats - at local deviice - and this has been found as a problem in old issue!

We should keep this in mind.

yip, this will local/remote deletion after N days will be available soonish, in one of the next versions.

the main-usecase that is targeted by these "one-sided ephemeral messages" is to allow users that are at some risk to enable a chat-mode where they would only have a record of the last few hours or days. keeping messages in rarely used chats longer does not help in this case and would be more a bug than a feature.

well, in this case you have the option not to use the function and everything is as before. no one says, it is a solution for everything :)

We should keep this in mind.

the function will clearly state under which circumstances messages are deleted. the ui will be similar to the one used for delete-from-server-after-N-days, see deltachat/deltachat-android#1257

[csb0730]

Ok, for this use case I agree with you.

But then we need a new issue for simply limit retained messages locally.
When if I'm not able to use the new N-days function I need the another N-messages function (per chat) to do the housekeeping job. For example at my samsung device N-messages limit can be set for SMS if desired.

[csb0730]

Shall I open an item at support forum for that or should we reopen existing issue?

[r10s]

feature request should go to the forum, yes :)

[csb0730]

Hi, it's existing since Oct 19:
https://support.delta.chat/t/issues-for-reliable-long-running-service-of-dc/652

If necessary I can open a new item with key points additionally? Maybe with same title than issue here at issue tracker?

[csb0730]

When this issue here is done I think it's a good base for just "limit retained history" of chat's

:-)
