We use PubSub only on our account jid, this use case is what PEP
was made for. If PEP is discovered we know that certain PubSub
features are supported, see: https://xmpp.org/extensions/xep-0163.html#defaults
The current check for <feature var='http://jabber.org/protocol/pubsub'/>
is pretty useless, as it just tells us that there is a PubSub implementation
but not much about the features. Only `publish` and `subscribe` are MUST
in XEP-0060 which is not enough for our needs.
If there is ever need to discover a generic PubSub implementation
that is not PEP we should check for all the PubSub features we need
instead of only for <feature var='http://jabber.org/protocol/pubsub'/>
- Add support for Pubsub Avatars
- Dont poll for vCard Updates, only use XEP-0153
- Dont cache vCards
- Store the avatar SHA of roster contacts in the DB
- Store the current SHA of each contact in the Contacts Object
- Move some code into the ConnectionVcard Class
_registered_name is None on a smacks resume.
Gajim creates on every connection attempt a new nbxmpp.NonBlockingClient
instance. This is why _registered_name is None when we go through a
smacks resume, because there is no bind event, and the new NonBlockingClient
instance has no knowledge of the previous successful bind.
- Use new parse_datetime() method
- Drop message with error if MAM doesnt supply a timestamp.
- If the user supplys an own timestamp, save it so we can decide in the
future how to display it.
Goal is to make the logger module easier to maintain in the future
- extract deduplication out into a own method, so we can use it
on its own in some other places.
- add new insert_into_logs() method
the DB fields we want to write to are passed as arguments, this makes
it so we dont have to change the method when we add or remove DB fields
in the future.
- instead of using get_jid_id() all around gajim to get the jid_id
before we write to the DB, we only have to pass the jid to
insert_into_logs(), it makes sure to get the correct jid_id or add
one in case it doesnt exist.
This handles every possible XEP-0082 timestamp
It has some additional options:
- Check if a timestring is a valid UTC timestamp, as required by some
XEPs (for example: XEP-0203)
- Return timestamp as datetime in UTC
- Return timestamp as datetime in localtime
- Return timestamp as epoch
We get our full JID on the bind event.
After that it is saved in the `registered_name` attr on the Connection
Object.
In case the bind never occured we get the bare JID from config.
- Condition type = groupchat is not needed because we drop messages
type groupchat that come from the user archive. To get these messages
we will query the MUC.
- Because of this the logging method save_if_not_exists() can be much
simpler
A missing stanza ID means, we will have to take some measures to make
sure we get no duplicates in the Database later on.
Also fix getting the origin-id. Third time is a charm.
The gaol why we need to determine what ID should be used as stanza-id,
is so we can use the stanza-id in the future for deduplication.
Case we are the sender:
Either we look for a origin-id element, which we will include in the
Future in all messages we send, or until then the ID we set on the
message as attr.
Case we are the receiver:
If our server supports mam:2 we take the ID of the result element,
because mam:2 injects the archive ID live into every message we
receive. If we dont have mam:2 we fall back to the ID of the message
attr.
- Refactor and clean up code around MamMessageReceivedEvent
- Goal is to add a GcMamMessageReceivedEvent later on
- For that cause added a raw-mam-message-received base event
This lets us attach all attributes of the base event to the
new event. Often Events trigger other Events. When that happens
we often want to keep all attr from the previous Event, and just
continue under a new Event. Until now all attr had to be pulled
out of `self.base_event` again.
- Refactor get_last_date_that_has_logs()
- use NATURAL JOIN in SQL query instead of multiple SELECT via
_build_contact_where
- make code more concise
- update method documentation
- use NATURAL JOIN in SQL query instead of multiple SELECT via
_build_contact_where
- make code more concise
- update method documentation
- Fix a bug where messages were displayed in wrong order when
they had the same timestamp
_continue_connection_request_privacy() should only trigger
once after we received the discoinfo on the hostname.
We do a discoinfo on all items that the server offers,
_continue_connection_request_privacy() was triggered on every received
discoinfo again, hence requesting metacontacts and delimiters again.
also _continue_connection_request_privacy() was called on every
discoinfo error, instead of only on a hostname discoinfo error.
This bug is only triggered if the server doesnt support privacy rules.
The purpose of
`if version and not gajim.contacts.get_contacts_jid_list()`
seemed to be that when cache.db is empty (maybe it was deleted)
`gajim.contacts.get_contacts_jid_list()` should come back empty.
So on an empty roster cache, version was set to None, so that we
request in any case a new roster.
The Problem is that `gajim.contacts.get_contacts_jid_list()` is not
a good indication for an empty cache.db. On start we trigger a
`RosterReceivedEvent` which does a DB query to get the roster. Even
if that DB query comes up empty, the Event is still pushed.
In the event handler `_nec_roster_received` in roster_window.py we
add then previously open controls and our self (if the option is set)
to the roster, making `gajim.contacts.get_contacts_jid_list()` return
these contacts and hence the condition in `request_roster()` always
False.
So the version is set in the roster request, and if there is no new
version on the server, we request no new roster even though we only
have ourself and previously open controls in our roster.
As a solution for this we delete the roster version from the config
in `RosterReceivedEvent` if the DB query comes back empty, which
triggers a new roster request.
Set restore timeout inactiv, this should be really an advanced option,
probably only set for specific MUCs not as default for every MUC.
Set restore_lines to 10, so the User has an indication that Gajim can
display history, and that there is probably a setting to adjust.
Set muc_restore_lines to 100, this is a try to get a reasonable amount
of history, especially in small Groupchats. Most server will limit this
to 20-50 anyway. The limit 100 is more of a precaution if we run into a
misconfigured server. This is intended as a workaround until we can
implement MAM for Groupchats.
muc_restore_timeout set to -1 means we want no particular time set, up
to which we request messages. But we should not deliberate request
messages we already have. Hence even if muc_restore_timeout is set
to -1, we should only request up to the last message we received.
Example:
If we receive a message the last message date is now.
If we restart Gajim and join the MUC again, `time.time() - timeout`
will be most likly smaller then when we received the last message
If the timeout is an hour, this would mean that many messages are requested
from the archive which we already received.
So we always want the most current timestamp (MAX).
Because some operations use the _timeout_commit() it happens that a timeout
is active while we shutdown.
This makes sure everything is commited before shutdown.
