Still lacks inter-tab communication to update state across tabs, i.e.
when sending a 1-on-1 message in one tab, it doesn't appear in another,
because that information is not available via the websocket connection.
- Create a new `Connection` class that extends Strophe.Connection and
move related code from `converse-core.js` into this class.
- Store the session in localStorage when using a worker
- Move XEP-0156 code to connection.js
This allows us to initialize the connection without needing to know the
domain.
- Add support for switching ephemerality after message creation
- Move more methods from ChatBox and ChatRoom to utils/stanza.js
- Rename 'ephemeral' to 'is_ephemeral' since it's a boolean
by not logging in automatically when `auto_login` is `false` and we're
using anonymous, external or prebind authentication.
For `authentication` set to `login` the situation is much more
ambiguous, since we don't have a clear distinction between wether we're
restoring a previous session (`keepalive`) or whether we're
automatically setting up a new session (`auto_login`).
So currently if *either* `keepalive` or `auto_login` is `true` and
`authentication` is set to `login`, then Converse will try to log the
user in.
It's unlikely that `keepalive` needs to be set to `false`, but there are
some edge cases where it might be useful.
Here's a breakdown of the different configurations of `keepalive` and `auto_join`:
---
* auto_login: false, keepalive: true
This is the default config. Users need to log in manually, but then
Converse will try to reconnect them when the page reloads.
* auto_login: true, keepalive: true
Also very popular configuration. Used with `credentials_url` or `prebind_url`.
* auto_login = `true`, keepalive = `false`
Not sure what this could be useful for. No currently known application.
* auto_login = `false`, keepalive = `false`
Useful when you want some kind of specific action to trigger login, but
you don't want to maintain that state across page reloads.
Also relevant when using a websocket connection with anonymous login.
With websocket it's impossible to maintain anonymous sessions across page
reload because the the session gets removed server-side as soon as the
websocket connection drops and the server won't accept a full JID with
password for an anonymous connection anyway (which could happen upon
page reload when Converse tries to login in again if `keepalive` was `true`).
In some cases, it might be desirable to clear cached chat messages once you've
reconnected to the XMPP server.
For example, if you want to prevent the chat history from getting too long or
if you want to avoid gaps in the chat history (for example due to MAM not
returning all messages since the last cached message).
If you're using OMEMO, then you probably don't want to set this setting to
``true``. OMEMO messages can be decrypted only once, so if they then
subsequently get cleared, you won't get the plaintext back.
- Fixes#1575. Height not properly set on MUC invitation list
- Add new configuration setting: `muc_mention_autocomplete_min_chars`
- Bugfix. `min_chars` setting for MUC mentions wasn't having an effect
