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)
Introspection query is failing with `type info not found for xxxx` error message if multiple actions are defined with reused PG scalars. The fix for the same.

The bulk of changes here is some shifting of code around and a little
parameterizing of functions for easier testing.
Also: comments, some renaming for clarity/less-chance-for-misue.
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.

* changes for poller-log
add various multiplexed query info in poller-log
* minor cleanup, also fixes a bug which will return duplicate data
* Live query poller stats can now be logged
This also removes in-memory stats that are collected about batched
query execution as the log lines when piped into an monitoring tool
will give us better insights.
* allow poller-log to be configurable
* log minimal information in the livequery-poller-log
Other information can be retrieved from /dev/subscriptions/extended
* fix few review comments
* avoid marshalling and unmarshalling from ByteString to EncJSON
* separate out SubscriberId and SubscriberMetadata

When compiling the graphql-engine binary with `-O2`, ghc-8.10 seems to
be stuck at the module `Server.Init` while consuming `17G` of RAM (for 5
minutes at least before I forcefully terminated the compilation). With
this pragma, ghc-8.10 now takes under `12G` to compile graphql-engine
binary.
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.

This also seems to squash a stubborn space leak we see with
subscriptions (linking to canonical #3388 for reference).
This may also fix some of the "Unexpected exception" websockets
exceptions we are now surfacing (see e.g. #4344)
Also: dev.sh: fix hpc reporting
Initial work on this done by Vamshi.
There are two implementations of a Cache, namely a bounded and an
unbounded variant. This can be elegantly captured in a type class.
In addition to reducing the amount of error-prone code in the
definition of the cache, this version reduces the amount of
error-prone code in usage sites of the cache, as it makes the cache
into an abstract object, so that a calling site cannot distinguish
between cache types. Any decision about what should be cached should
be made through the interface of a cache, rather than at the callsite,
and this is captured by this variant.

The previous check was too conservative and acquired a lock on the
schema cache in situations where it was unnecessary. This change
exposes the logic run_sql uses to determine whether to use the
metadata check to make the check more precise.
* 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.

* add expiry time to webhook user info
This also adds an optional message to webhook errors: if we fail to
parse an expiry time, we will log a warning with the parse error.
* refactored Auth
This change had one main goal: put in common all expiry time
extraction code between the JWT and WebHook parts of the
code. Furthermore, this change also moves all WebHook specific code to
its own module, similarly to what is done for JWT.
* Remove dependency on string-conversions in favor of text-conversions
string-conversions silently uses UTF8 instead of being explicit about
it, and it uses lenientDecode when decoding ByteStrings when it’s
usually better to reject invalid UTF8 input outright. text-conversions
solves both those problems.

Writing to a mutable var is a particularly potent source of leaks since
it mostly defeats GHC's analysis. Here we add assertions to all mutable
writes, and fix a couple spots where we wrote some thunks to a mutable
var (compiled with -O2).
Some of these thunks were probably benign, but others looked liked they
might be retaining big args. Didn't do much analysis, just fixed.
Actually pretty happy with how easy this was to use and as a diagnostic,
once I sorted out some issues. We should consider using it elsewhere,
and maybe extending so that we can use it with tests, enable when
`-fenable-assertsions` etc.
Relates #3388
Also simplified codepaths that use `AcceptWith`, which has unnecessary
`Maybe` fields.
We’re lucky that this never bit us. For the most part, these rules
aren’t actually used; most code programs against ArrowCache and doesn’t
get specialized enough for these rules to fire.
Even if we did have code that could trigger this rule, the situations
where it would actually fire are slim. In order for the rule to
typecheck at all, both sides of the pair being passed through the arrow
must have exactly the same type. Of course, that would just make this
even more hellish to debug.
Rewrite rules are dangerous.
* 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.
This is the result of a general audit of how we fork threads, with a
detour into how we're using mutable state especially in websocket
codepaths, making more robust to async exceptions and exceptions
resulting from bugs.
Some highlights:
- use a wrapper around 'immortal' so threads that die due to bugs are
restarted, and log the error
- use 'withAsync' some places
- use bracket a few places where we might break invariants
- log some codepaths that represent bugs
- export UnstructuredLog for ad hoc logging (the alternative is we
continue not logging useful stuff)
I had to timebox this. There are a few TODOs I didn't want to address.
And we'll wait until this is merged to attempt #3705 for
Control.Concurrent.Extended
