* Test working through a backlog of change events
* Use a slightly more performant threaded http server in eventing pytests
This helped locally but not on CI it seems...
* Rework event processing for backpressure. Closes#3839
With loo low `HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL` and/or slow webhooks
and/or too small `HASURA_GRAPHQL_EVENTS_HTTP_POOL_SIZE` we might
previously check out events from the DB faster than we can service them,
leading to space leaks, weirdness, etc.
Other changes:
- avoid fetch interval sleep latency when we previously did a non-empty
fetch
- prefetch event batch while http pool is working
- warn when it appears we can't keep up with events being generated
- make some effort to process events in creation order so we don't
starve older ones.
ALSO NOTE: HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL changes semantics
slightly, since it only comes into play after an empty fetch. The old
semantics weren't documented in detail, so I think this is fine.

* Add check expresion to update permissions (close#384)
* wip on conflict behavior
* Handle upserts for views properly
* Use insert check if there is no update check
* Fix the test
* Improve error message slightly
Co-authored-by: Vamshi Surabhi <0x777@users.noreply.github.com>
* fix nested insert with returning computed fields gives error, fix#3609
* revert using ordered hashmaps, sort columns based on ordinal postion
* fix 1. keys order 2. json/jsonb column value in nested insert returning
* add a note for sorted columns
* cast 'VALUES' expression as table row type
* use single CTE expression for generating returning for nested inserts
This fixes#3759. Also, while we’re at it, also improve the way
invalidations are synced across instances so enums and remote schemas
are appropriately reloaded by the schema syncing process.
* WIP: Remove hdb_views for inserts
* Show failing row in check constraint error
* Revert "Show failing row in check constraint error"
This reverts commit dd2cac29d0.
* Use the better query plan
* Simplify things
* fix cli test
* Update downgrading.rst
* remove 1.1 asset for cli
- Move MonadBase/MonadBaseControl instances for TxE into pg-client-hs
- Set the -qn2 RTS option by default to limit the parallel GC to 2
threads
- Remove eventlog instrumentation
- Don’t rebuild the schema cache again after running a query that needs
it to be rebuilt, since we do that explicitly now.
- Remove some redundant checks, and relocate a couple others.
This changes TableCoreCacheT to internally record dependencies at a
per-table level. In practice, this dramatically improves the performance
of building permissions: it makes it far, far less likely for
permissions to be needlessly rebuilt because some unrelated table
changed.
* export metadata without nulls, empty arrays
* property tests for 'ReplaceMetadata' using QuickCheck
-> Derive Arbitrary class for 'ReplaceMetadata' dependant types
* reduce property test cases number to 30
QuickCheck generates the `ReplaceMetadata` value really large
for higher number test cases. Encoded JSON for such values is large and
consumes more memory. Thus, CI is giving up while running property
tests.
* circle-ci: Add property tests as saperate job
* add no command mode to tests
* add yaml.v2 to go mod
* remove indirect comment for yaml.v2 dependency
Instead of
'WITH some_alias (SELECT * from some_func()) SELECT <rows> FROM some_alias'
for SQL function queries, Use
'SELECT <rows> FROM some_func() AS some_alias'
* save permissions, relationships and collections in catalog with 'is_system_defined'
* Use common stanzas in the .cabal file
* Refactor migration code into lib instead of exe
* Add new server test suite that exercises migrations
* Make graphql-engine clean succeed even if the schema does not exist
* Separate DB and metadata migrations
* Refactor Migrate.hs to generate list of migrations at compile-time
* Replace ginger with shakespeare to improve performance
* Improve migration log messages
* allow customizing GraphQL root field names, close#981
* document v2 track_table API in reference
* support customising column field names in GraphQL schema
* [docs] add custom column fields doc in API reference
* add tests
* rename 'ColField' to 'ColumnField'
* embed column's graphql field in 'PGColumnInfo'
-> Value constructor of 'PGCol' is not exposed
-> Using 'parseJSON' to construct 'PGCol' in 'FromJSON' instances
* avoid using 'Maybe TableConfig'
* refactors & 'custom_column_fields' -> 'custom_column_names'
* cli-test: add configuration field in metadata export test
* update expected keys in `FromJSON` instance of `TableMeta`
* use `buildSchemaCacheFor` to update configuration in v2 track_table
* remove 'GraphQLName' type and use 'isValidName' exposed from parser lib
* point graphql-parser-hs library git repo to hasura
* support 'set_table_custom_fields' query API & added docs and tests
This fixes an issue where queries could incorrectly be considered
reusable if a variable was used in two positions: one where it affected
SQL generation and one where it did not.
