This patches add handling for unseen messages counter, and last message received. The
counters are retrieved from DB on startup, they updated in-memory. Frontend are expected
to have their own in-memory counter too, the backend one is used for re-sync (e.g.; on page
reload).
Bridge methods are added to retrieve the state, and indicate which message has been seen
last by user. A signal is sent on counter reset to all frontends can synchronise.
This is currently local only, but it should be compatible with a future XEP-0490 (Message
Displayed Synchronization) implementation.
A constraint name was missing on the `PubsubNode.pep` column, resulting in a crash when
trying to generate the initial database on launch with an empty `local_dir`.
Migration script introducing the column (f4cb5fc600c7_add_missing_pep_check_constraint.py)
has been updated too. Another migration script has been made to add the constraint to
existing DB (only if they are missing).
- Use `client` instead of `profile`
- Add `decrypt_value_by_profile` which is notably useful on client startup, when the
encrypted password needs to be retrieved, and the `SatXMPPEntity` instance is not yet
created.
- Add type hints/update docstrings

When returning pending queries `Deferred`, a caller could add its own callbacks/errbacks
and modify the result. When another caller was reusing the `Deferred`, it got the modified
result (which could be `None`) instead of the expected `DiscoInfo`.
This has been fixed by creating and new `Deferred` on each request, and chaining it to the
original pending queries using the new `fork_deferred` helper method, so each caller get
its own isolated `Deferred`.
In `fork_deferred`, `cancel` method is used to call the parent Deferred `cancel`, to avoid
a wrong Exception propagation and the chained Deferred to be eventually called twice
(triggering `AlreadyCalledError`).
`cleanup_query` has been moved above `infos_cb` callback, as it should be the first
callback called.
When a `remote-server-not-found` stanza error is received, cache the whole server, so all
queries to a entity from this server will be blocked by the cache, avoiding unnecessary
network requests.
During cache check, full entity JID is checked first, then its server.
When many queries are run in parallel (e.g. during initial sync on startup), the same
entity may be disco queries several times in parallel. To avoid network request
duplication, we now track pending queries, and re-use them in this case.
- Add `wal_checkpoint()` method to manually checkpoint Write-Ahead logs.
- Do the checkpoint on startup to start clean and avoid delay on first login.
- Add an `unload` method to clean DB on exit, and do a checkpoint there.
We sometimes to need to call another method in asyncio context when we already are in this
context. With the `@aio` decorator which makes the method return a `Deferred`, it was
necessary to use a ping pong between `Deferred` and `Future`.
This patch adds a `aio_func` attribute which directly returns the wrapped asyncio method,
so it can now be awaited directly.
- Fix data types, and use quotes data type to avoid immediate evaluation on Python < 3.14
- Better error catching folling change in `get_infos` in `memory.disco`.
- Some code modernisation (async coroutine).
- Error raised by `disco_info` where not properly handler, resulting in an exception
instead of appropriate logging and return value.
- `async` coroutines, type hints
- the XEP-0115 implementation has been completed with validation, caps node handling in
disco requests, hash generation fixes, and real support for xml:lang.
- the `generate_hash` method has been moved from disco where it's not used anymore to
XEP-0115.
- Disco doesn't hash systematically, it nos use a per-jid cache for non XEP-0115
supporting client.
- code modernisation, with use of `get_plugin_data` for Client data in XEP-0115, type
hints, etc.
- More comments have been added to link algorithms steps to the relevant part in
specification.
Tx-XMPP 0.12 has beaking change in `discoFeature.identities` because it now supports
`xml:lang` attribute, so this update implies updating the code everywhere were this is
used.
- Implement `presence` access model for PEP nodes.
- Add PEP auto-subscription (`+notify` handling)
- New `get_pep_last_items` storage method to retrieve in a single query items to send to
auto-subscribers.
- Online resource tracking.
This completes the PEP support.
rel 476
A new `max_items` field has been added to `PubsubNode`. `0` means `max`. If any >0 value
is used, items will be automatically deleted by `cache_pubsub_items`. Items are currently
discarded (i.e. no notification is sent), this is the same behaviour as in legacy Libervia
Pubsub (formerly "SàT Pubsub").
rel 476
- Added `on_extended_disco()` handler.
- Added `with_parent=True` to all `get_pubsub_node()` calls to prevent lazy load errors in
access checks.
rel 476
Registered XEP-0499 handler in `profile_connecting()` and added it to
plugin dependencies.
Added `with_parent` and `with_link` parameters for eager loading of parent and linked_node
relationships.
Fixed CTE to include all children (not just base nodes) and use `selectinload` for parent
to avoid cartesian products.
rel 476
Add methods to handles the relationships which were already present in storage.
This plugins add methods to handle validation and rules from the specs.
`get_pubsub_node_children` helper method has been added to storage.
- update queries to handle correctly the `before=""` case and RSM order (older to newer)
while having correct order when `max_items` without RSM is used (then order it newer to
older).
- put RSM code path in a separated method for better readability.
- check values of `max_items` and `from_index` and raise exception is they are not
positive
- when using `before` or `after`, check that the item ID used as reference exists, and
raise an exception otherwise.
- updated docstring to reflect the new behaviour.
- update pubsub cache use of `get_items` with RSM, to adapt to new behaviour.
rel 476
New `jid`, `secret` and `autoconnect` field are used for component settings. When used,
backend will automatically create the profile and set its relevant parameters, or check
that existing profile is in sync (and update it if necessary).
This make component installation easier to Libervia, as it is not
necessary anymore to use the CLI frontend to install a component.
rel 476
This is a huge configuration refactoring.
The configuration system now uses Pydantic settings, with better validation, better
support for environment variables and other goodies.
The main config files now use TOML instead of INI, this allow for better handling of
complex types, notably dict.
Plugins, components and frontends can declare their config settings in a class which will
be imported dynamically.
- Arguments are now grouped in a new `PageData` NamedTuple, making it simpler to use, and
easier to extend.
- Page index is automatically calculated, and can be checked in callback to know which
page to show.
- Form send by calling entity is automatically parsed, using original form to instantiate
the right field types.
- A new `DataForm.get_field` method use Generic type as second argument to retrieve the
right field when getting a `submit` form.
- Updated all classes registering Ad-Hoc commands to use the new system and simplify the
code.
ORM was used, resulting in deserialisation/reserialisation of value checked for race
condition during update. In addition to the overhead, this could lead to modification even
if the value didn't change (e.g., because of JSON key order changed).
The raw value is not used to check if the row has not change between `select` and
`update`, making the method more robust.
- `parent_node` and `linked_node` can now be specified in `set_pubsub_node`.
- `get_pubsub_nodes` has been rewritten to recursively traverse a tree and retrieve nodes
matching criteria and their linking nodes/children/items.
rel 463
Add columns to handle `access_model` and `publish_model` and a table for `affiliations`.
With those new data, components handling pubsub can now manage permissions correctly.
rel 462
There are 2 concurrent models, this one is an historical legacy. The type to use the one
from `libervia.backend.models.core`, and it will progressively be used everywhere and
fully based on Pydantic.
