These changes also add a new type, PGColumnType, between PGColInfo and
PGScalarType, and they process PGRawColumnType values into PGColumnType
values during schema cache generation.
query templates is a little known feature that lets you template rql
queries and serve them as rest apis. This is not relevant anymore
given the GraphQL interface and getting rid of it reduces the dev
time when adding features in few subsystems.
This feature has never been used outside hasura's internal projects or
documented or exposed through console and hence can safely be removed.
* fix bug in audience check while verifying JWT
- previously the check was converting the audience type into a string
and then comparing with the conf value. all audience types (as it is a
string or URI) will convert to plain strings
- use the Audience type from the jose library for comparing
* add docs for audience
* add issuer check as well
* docs minor syntax fix
* skip audience check if not given in conf
* minor docs update
* qualify import jose library
* Bump node-sass to version ^4.12.0
This avoids sass/node-sass#2632, which causes compilation failures on
Node v12.x.
* Do most of the work in /pg_dump in Haskell instead of shell
The shell version caused problems on non-Linux systems since it relied
on the non-POSIX -i option for sed, which works slightly differently on
BSD and macOS.
This PR builds console static assets into the server docker image at `/srv/console-assets`. When env var `HASURA_GRAPHQL_CONSOLE_ASSETS_DIR=/srv/console-assets` or flag `--console-assets-dir=/srv/console-assets` is set on the server, the files in this directory are served at `/console/assets/*`.
The console html template will have a variable called `cdnAssets: false` when this flag is set and it loads assets from server itself instead of CDN.
The assets are moved to a new bucket with a new naming scheme:
```
graphql-engine-cdn.hasura.io/console/assets/
/common/{}
/versioned/<version/{}
/channel/<channel>/<version>/{}
```
Console served by CLI will still load assets from CDN - will fix that in the next release.
Changes compared to `/v1alpha1/graphql`
* Changed all graphql responses in **/v1/graphql** endpoint to be 200. All graphql clients expect responses to be HTTP 200. Non-200 responses are considered transport layer errors.
* Errors in http and websocket layer are now consistent and have similar structure.
* build schema cache function without db setup
The setup shouldn't happen for sync. The database is already setup by the instance which generated the event. This means that the sync is now faster.
* use SQL loop to drop hdb_views schema views and routines with ordering
This avoids deadlocks when schema is being changed concurrently
* schema sync now only processes the latest event
This becomes useful when a lot of schema change
events happen while we are still processing an
earlier event.
* split stm transactions when snapshotting to make it faster
* mx subs: push to both old and new sinks at the same time
* expose dev APIs through allowed APIs flag
* add types to represent unparsed http gql requests
This will help when we add caching of frequently used ASTs
* query plan caching
* move livequery to execute
* add multiplexed module
* session variable can be customised depending on the context
Previously the value was always "current_setting('hasura.user')"
* get rid of typemap requirement in reusable plan
* subscriptions are multiplexed when possible
* use lazytx for introspection to avoid acquiring a pg connection
* refactor to make execute a completely decoupled module
* don't issue a transaction for a query
* don't use current setting for explained sql
* move postgres related types to a different module
* validate variableValues on postgres before multiplexing subs
* don't user current_setting for queries over ws
* plan_cache is only visible when developer flag is enabled
* introduce 'batch size' when multiplexing subscriptions
* bump stackage to 13.16
* fix schema_stitching test case error code
* store hashes instead of actual responses for subscriptions
* internal api to dump subscriptions state
* remove PlanCache from SchemaCacheRef
* allow live query options to be configured on server startup
* capture metrics for multiplexed subscriptions
* more metrics captured for multiplexed subs
* switch to tvar based hashmap for faster snapshotting
* livequery modules do not expose internal details
* fix typo in live query env vars
* switch to hasura's pg-client-hs
* read version from env var at build time (close#1398)
* remove un-used imports, edit makefile
* edit makefile to add new targets and export variables
* only export VERSION in makefile
* read version by executing the script if env var is absent
1. Haskel library `pg-client-hs` has been updated to expose a function that helps listen to `postgres` notifications over a `channel` in this [PR](https://github.com/hasura/pg-client-hs/pull/5)
2. The server records an event in a table `hdb_catalog.hdb_cache_update_event` whenever any `/v1/query` (that changes metadata) is requested. A trigger notifies a `cache update` event via `hasura_cache_update` channel
3. The server runs two concurrent threads namely `listener` and `processor`. The `listener` thread listens to events on `hasura_cache_update` channel and pushed into a `Queue`. The `processor` thread fetches events from that `Queue` and processes it. Thus server rebuilds schema cache from database and updates.
* read cookie while initialising websocket connection (fix#1660)
* add tests for cookie on websocket init
* fix logic for tests
* enforce cors, and flag to force read cookie when cors disabled
- as browsers don't enforce SOP on websockets, we enforce CORS policy
on websocket handshake
- if CORS is disabled, by default cookie is not read (because XSS
risk!). Add special flag to force override this behaviour
* add log and forward origin header to webhook
- add log notice when cors is disabled, and cookie is not read on
websocket handshake
- forward origin header to webhook in POST mode. So that when CORS is
disabled, webhook can also enforce CORS independently.
* add docs, and forward all client headers to webhook
