* dev.sh: bump version due to addition of croniter python dependency
* server: fix an introspection query caching issue (fix#4547) (#4661)
Introspection queries accept variables, but we need to make sure to
also touch the variables that we ignore, so that an introspection
query is marked not reusable if we are not able to build a correct
query plan for it.
A better solution here would be to deal with such unused variables
correctly, so that more introspection queries become reusable.
An even better solution would be to type-safely track *how* to reuse
which variables, rather than to split the reusage marking from the
planning.

* Don't compile in developer APIs by default
* Tighten up handling of admin secret, more docs
Store the admin secret only as a hash to prevent leaking the secret
inadvertently, and to prevent timing attacks on the secret.
NOTE: best practice for stored user passwords is a function with a
tunable cost like bcrypt, but our threat model is quite different (even
if we thought we could reasonably protect the secret from an attacker
who could read arbitrary regions of memory), and bcrypt is far too slow
(by design) to perform on each request. We'd have to rely on our
(technically savvy) users to choose high entropy passwords in any case.

* server/docs: add instructions to fix loss of float precision in PostgreSQL <= 11 (#5187)
This adds a server flag, --pg-connection-options, that can be used to set a PostgreSQL connection parameter, extra_float_digits, that needs to be used to avoid loss of data on older versions of PostgreSQL, which have odd default behavior when returning float values. (fixes#5092)

* Lower stack chunk size in RTS to reduce thread STACK memory (closes#5190)
This reduces memory consumption for new idle subscriptions significantly
(see linked ticket).
The hypothesis is: we fork a lot of threads per websocket, and some of
these use slightly more than the initial 1K stack size, so the first
overflow balloons to 32K, when significantly less is required.
However: running with `+RTS -K1K -xc` did not seem to show evidence of
any overflows! So it's a mystery why this improves things.
GHC should probably also be doubling the stack buffer at each overflow
or doing something even smarter; the knobs we have aren't so helpful.

* Fix latency buckets for telemetry data
These must have gotten messed up during a refactor. As a consequence
almost all samples received so far fall into the single erroneous 0 to
1K seconds (originally supposed to be 1ms?) bucket.
I also re-thought what the numbers should be, but these are still
arbitrary and might want adjusting in the future.

!!! WARNING !!!
Since all fields accept `null`, they all are technically optional in
the new schema. Meaning there's no such thing as a missing mandatory
field anymore: a field that doesn't have a default value, and which
therefore isn't labelled as "optional" in the schema, will be assumed
to be null if it's missing, meaning it isn't possible anymore to have
an error for a missing mandatory field. The only possible error is now
when a optional positional argument is omitted but is not the last
positional argument.
* [skip ci] cleanup of int scalar parser
* [skip ci] retro-compatibility of offset as string
* [skip ci] Remove commit from commit_diff.txt
Although strictly speaking we don't know if this will work correctly in PDV
if we would implement query plan caching, the fact is that in the theoretical
case that we would have the same issue in PDV, it would probably apply not just
to introspection, and the fix would be written completely differently. So this
old commit is of no value to us other than the heads-up "make sure query plan
caching works correctly even in the presence of unused variables", which is
already part of the test suite.
* Add MonadTrace and MonadExecuteQuery abstractions (#5383)
* [skip ci] Fix accumulation of input object types
Just like object types, interface types, and union types, we have to avoid
circularities when collecting input types from the GraphQL AST.
Additionally, this fixes equality checks for input object types (whose fields
are unordered, and hence should be compared as sets) and enum types (ditto).

As we need to log all messages recieved/sent by the websocket server,
it makes sense to log them as part of the websocket server event logs.

* [skip ci] update commit_diff with new commits added in master
* Bugfix to support 0-size HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE
Also some minor refactoring of bounded cache module:
- the maxBound check in `trim` was confusing and unnecessary
- consequently trim was unnecessary for lookupPure
Also add some basic tests
* Support only the bounded cache, with default HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE of 4000. Closes#5363

* [skip ci] fix setup to fix backend only test
the order in which permission checks are performed on the branch is
slightly different than on master, resulting in a slightly different
error if there are no other mutations the user has access to. By
adding update permissions, we go back to the expected case.

* [skip ci] Fix two warnings
We used to lookup the objects that implement a given interface by filtering all
objects in the schema document. However, one of the tests expects us to
generate a warning if the provided `implements` field of an introspection query
specifies an object not implementing some interface. So we use that field
instead.

* fix 'ID' input coercing & action 'ID' type relationship mapping
* include ASTs in MonadExecuteQuery
* needed for PRO code-base
* Delete code for "interfaces implementing ifaces" (draft GraphQL spec)
Previously I started writing some code that adds support for a future GraphQL
feature where interfaces may themselves be sub-types of other interfaces.
However, this code was incomplete, and partially incorrect. So this commit
deletes support for that entirely.
* Ignore a remote schema test during the upgrade/downgrade test
The PDV refactor does a better job at exposing a minimal set of types through
introspection. In particular, not every type that is present in a remote schema
is re-exposed by Hasura. The test
test_schema_stitching.py::TestRemoteSchemaBasic::test_introspection assumed that
all types were re-exposed, which is not required for GraphQL compatibility, in
order to test some aspect of our support for remote schemas.
So while this particular test has been updated on PDV, the PDV branch now does
not pass the old test, which we argue to be incorrect. Hence this test is
disabled while we await a release, after which we can re-enable it.
This also re-enables a test that was previously disabled for similar, though
unrelated, reasons.
* add haddock documentation to the action's field parsers
* Deslecting some tests in server-upgrade
Some tests with current build are failing on server upgrade
which it should not. The response is more accurate than
what it was.
Also the upgrade tests were not throwing errors when the test is
expected to return an error, but succeeds. The test framework is
patched to catch this case.

* Add bulldozer auto-merge and -update configuration
We still need to add the github app (as of time of opening this PR)
Afterwards devs should be able to allow bulldozer to automatically
"update" the branch, merging in parent when it changes, as well as
automatically merge when all checks pass.
This is opt-in by adding the `auto-update-auto-merge` label to the PR.
* Remove 'bulldozer' config, try 'kodiak' for auto-merge
see: https://github.com/chdsbd/kodiak
The main issue that bit us was not being able to auto update forked
branches, also:
https://github.com/palantir/bulldozer/issues/66https://github.com/palantir/bulldozer/issues/145
* Cherry-picked all commits
* [skip ci] Slightly improve formatting

This undoes a cherry-pick of 34288e1eb5 that was
already done previously in a6450e126b, and
subsequently fixed for PDV in 70e89dc250

Introspection queries accept variables, but we need to make sure to
also touch the variables that we ignore, so that an introspection
query is marked not reusable if we are not able to build a correct
query plan for it.
A better solution here would be to deal with such unused variables
correctly, so that more introspection queries become reusable.
An even better solution would be to type-safely track *how* to reuse
which variables, rather than to split the reusage marking from the
planning.

* Update graphql-parser-hs and hence use `Scientific` directly
The new version of graphql-parser-hs returns Scientific and Integer
rather than Double and Int32, respectively. So we now need to do less
work in graphql-engine, and we can process larger numbers.
In practice, this means that when inserting a bigint, we no longer
need to specify the inserted integer as text. This is also
represented in the updated tests.
* Generate int overflow error on insert
* Document bigint insertion support in changelog
* allow underscore prefix and special characters in json path
* server: Rewrite/refactor JSONPath parser
The JSONPath parser is also rewritten, the previous implementation
was written in a very explicitly “recursive descent” style, but the whole
point of using attoparsec is to be able to backtrack! Taking advantage
of the combinators makes for a much simpler parser.

* server: add tests for track_table of a materialized view
In the context of #91, we discovered that materialized views were
already "automagically" supported; to ensure we don't regress on this
accidental but welcome change, this patch adds simple tests.
This is basically just a copy of `track_untrack_table`, but for
materialized views.
* Expand abbreviations
Co-authored-by: Alexis King <lexi.lambda@gmail.com>
The setup in several tests was using `ST_GeomFromText`, which expects
data in the OGC WKT format, but was providing the SRID in the text
itself, which is part of the EWKT format.
The fix was simply to replace all calls to `ST_GeomFromText` to
`ST_GeomFromEWKT`.

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.
We mostly want to do this to make queries against information_schema
tables work, which the console cares about. information_schema tables
use types like sql_identifier, which have no corresponding array types
defined! Therefore, in order to generate valid queries for _in and _nin
conditions, we need to treat them as their base types, instead.
* 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
The intention was to make this two cases, using a top-level YAML list.
The result was one test with duplicate keys (effectively only running
the second test). This is an error that's now flagged by newer ruamel.
Both tests needed to be "corrected" to pass and need review.
This fix is a little ugly, but it’s the only simple solution without a
significant refactoring that restructures the relationship between
GraphQL/Validate and GraphQL/Resolve. The ugliness should go away if we
implement something like #2801.
* 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`

* 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.
Update trigger is failing if any json/geometry columns are present in
event payload rows. Use '*<>' operator instead of '<>' to compare the
internal binary representation of rows if '<>' doesn’t work.
* initial raster support

* new type for raster values
Suggested by @lexi-lambda
* replace `SEUnsafe "NULL"` with SENull
* use positional arguments in SQL functions
* only allow omitting set of last arguments in functions
* disallow omitting of a non default argument in functions
These changes also add a new type, PGColumnType, between PGColInfo and
PGScalarType, and they process PGRawColumnType values into PGColumnType
values during schema cache generation.
* allow altering type of a column iff session vars are defined in permissions
* use a sum type to define dependency reason
* set jwt expiry test's expiry time to 4 seconds
* derive Data instance for necessary types to simplify 'hasStaticExp'
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.
Currently, we allow tracking of a table with the same name as an already tracked function, and vice-versa. This causes an issue when querying from GraphQL since it will only query the table and not the function. I've made changes to disallow this by throwing an error.
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.

### Solution and Design
<!-- How is this issue solved/fixed? What is the design? -->
<!-- It's better if we elaborate -->
#### Reducing execution time of tests
- The Schema setup and teardown, which were earlier done per test method, usually takes around 1 sec.
- For mutations, the model has now been changed to only do schema setup and teardown once per test class.
- A data setup and teardown will be done once per test instead (usually takes ~10ms).
- For the test class to get this behaviour, one can can extend the class `DefaultTestMutations`.
- The function `dir()` should be define which returns the location of the configuration folder.
- Inside the configuration folder, there should be
- Files `<conf_dir>/schema_setup.yaml` and `<conf_dir>/schema_teardown.yaml`, which has the metadata query executed during schema setup and teardown respectively
- Files named `<conf_dir>/values_setup.yaml` and `<conf_dir>/values_teardown.yaml`. These files are executed to setup and remove data from the tables respectively.
#### Running Graphql queries on both http and websockets
- Each GraphQL query/mutation is run on the both HTTP and websocket protocols
- Pytests test parameterisation is used to achieve this
- The errors over websockets are slightly different from that on HTTP
- The code takes care of converting the errors in HTTP to errors in websockets
#### Parallel executation of tests.
- The plugin pytest-xdist helps in running tests on parallel workers.
- We are using this plugin to group tests by file and run on different workers.
- Parallel test worker processes operate on separate postgres databases(and separate graphql-engines connected to these databases). Thus tests on one worker will not affect the tests on the other worker.
- With two workers, this decreases execution times by half, as the tests on event triggers usually takes a long time, but does not consume much CPU.
From `alpha-40` we've been using a `WHERE` clause to fetch required rows and generate mutation response. This has a few limitations like the requirement of a primary key/unique constraint. This also returns inconsistent data on `delete` mutation as mentioned in #1794.
Now, we're using `VALUES (..)` (refer [here](https://www.postgresql.org/docs/current/sql-values.html)) expression to form virtual table rows in `SQL` to generate mutation response.
Internal changes:-
- Not to use primary key/unique constraint columns:-
- Revert back to `ConstraintName` from `TableConstraint` in `TableInfo` type
- Remove `tcCols` field in `TableConstraint` type
- Modify `table_info.sql` and `fetchTableMeta` function `SQL`
- A test case to perform `delete` mutation and returning relational objects.
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.
If returning field contains nested selections then mutation is performed in two steps
1. Mutation is performed with returning columns of any primary key and unique constraints
2. returning fields are queried on rows returned by selecting from table by filtering with column values returned in Step 1.
Since mutation takes two courses based on selecting relations in returning field, it is hard to maintain sequence of prepared arguments (PrepArg) generated while resolving returning field. So, we're using txtConverter instead of prepare to resolve mutation fields.
* support jsonb and geometry operators on RQL bool exps, close#1408
* add tests for jsonb operators in /v1/query
TODO:-
-> add tests for geometry (postgis) operators
* support parsing session variables for st_d_within and has_key ops
-> Add tests for boolExp operators and select permissions
* improve parsing $st_d_within op's json value logic
When using self referential relationships in boolean expressions, the exists clause incorrectly uses the table names to qualify columns which will be the same for parent table and the child table. This is now fixed by generating unique aliases as we traverse down the relationships.

* rename SelFld to more readable TableAggFld
* rename agg to aggregate
Better SQL generation for select queries (the query plans will be the same but much more readable). This closes some long standing issues (#6, #121, #278).
This is breaking change where bigint and bigserial Postgres types will be encoded as GraphQL String types, as opposed to Int as present in earlier releases.
Input types were already encoded as String.
This is achieved by selecting `bigint` and `bigserial` columns as `text`s in the SQL query: `select "big_id"::text ..` instead of `select "big_id" .. `.
Reason for that change is outlined in #633 where JavaScript cannot decode 64 bit Integers.
Insert trigger function: If query affects no rows then return `null`
Insert trigger function is modified to have
`IF r IS NULL THEN RETURN null; ELSE RETURN r; END IF;` in return statement.
