Fixes https://github.com/PostgREST/postgrest/issues/1512
Helps on environments where you can't send unix signals(Windows, managed
containers). Also provides better UX for schema reloads - NOTIFY
can be sent from pg clients(psql, pgadmin).
`NOTIFY pgrst` - with no payload - should be done to reload the schema cache.
Notifications with a payload will be ignored.
The channel can be enabled with `db-channel-enabled`(false by default)
and its name can be configured with `db-channel`.
The LISTEN thread uses a dedicated pg connection.
This connection is recovered if it fails.
A debounce of 1ms is done in case too many NOTIFYs arrive.
Previously, the linters would use the cached build artefacts from
building postgrest with -fno-spec-constr via stack.yaml. Potentially
passing it to the linter build explicitly will fix recent out-of-memory
issues.
The style check was failing due to a changed stack.yaml.lock file.
(That file still should be updated, but this is not where it should
cause a failure.)
* Update resolver to lts-13.29 and add lock file to repository
* Upgrade stack version
* Save cache after building dependencies only to have faster feedback loop when tests fail
* Move private functions from QueryBuilder to a separate Private module
* Move more functions over to private trying to make compilation consume less memory
* Split private in 4 modules
* Remove unused LambdaCase pragma
* Add profile to memory-tests.sh so it can find postgrest executable
* Move save dependencies before building and running tests for faster feedback loop
* circleci: Update stack versions from 1.1.2 to 1.9.3.
* circleci: Don't try to install unused packdeps and cabal-install.
* memory-tests: Rely on `stack build` to have been called already.
This happens in the previous circleci step.
* Update config default; Copy non-defaults
* Update .stylish-haskell config version to match pgrst
* Apply stylish haskell to all files
* CircleCI config
* Remove redundant import.
What is used from Network.HTTP.Types.Headers is also exported by Network.HTTP.Types.
* Grouped imports
* Show un-styled files on CircleCI failure
* Fix styling imports
* Apply adhoc standard correctly
