chore(deps): update actions/checkout action to v7.0.1

docs: fix example jwt expiration epoch
Issue: the example epoch date is wrapped in parentheses. This causes the server to return PGRST303: "The JWT 'exp' claim must be a number" Fix: remove parentheses (cherry picked from commit 69d21a82c9)

+# Contributing to PostgREST
+
+**First:** if you're unsure or afraid of _anything_, just ask or
+submit the issue or pull request anyways. You won't be yelled at
+for giving your best effort. The worst that can happen is that
+you'll be politely asked to change something. We appreciate any
+sort of contributions, and don't want a wall of rules to get in the
+way of that.
+
+However, for those individuals who want a bit more guidance on the
+best way to contribute to the project, read on. This document will
+cover what we're looking for. By addressing all the points we're
+looking for, it raises the chances we can quickly merge or address
+your contributions.
+
+## Issues
+
+For questions on how to use PostgREST, please use
+[GitHub discussions](https://github.com/PostgREST/postgrest/discussions).
+
+### Reporting an Issue
+
+* Make sure you test against the latest [stable release](https://github.com/PostgREST/postgrest/releases/latest)
+  and also against the latest [nightly release](https://github.com/PostgREST/postgrest/releases/tag/nightly).
+  It is possible we already fixed the bug you're experiencing.
+
+* Provide steps to reproduce the issue, including your OS version and
+  the specific database schema that you are using.
+
+* Please include SQL logs for issues involving runtime problems. To obtain logs first
+  [enable logging all statements](http://www.microhowto.info/howto/log_all_queries_to_a_postgresql_server.html),
+  then [find your logs](http://blog.endpoint.com/2014/11/dear-postgresql-where-are-my-logs.html).
+
+* If your database schema has changed while the PostgREST server is running,
+  [send the server a `SIGUSR1` signal](http://postgrest.org/en/latest/admin.html#schema-reloading) or restart it to ensure the schema cache
+  is not stale. This sometimes fixes apparent bugs.
+
+## Code
+
+We have a fully nix-based development environment with many tools for a smooth development workflow available.
+Check the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md) on how to set it up and use it.
+
+### Haskell Conventions
+
+* All contributions must pass the tests before being merged. When
+  you create a pull request your code will automatically be tested.
+
+* All code must also pass [hlint](http://community.haskell.org/~ndm/hlint/) and [stylish-haskell](https://github.com/jaspervdj/stylish-haskell)
+  with no warnings. This helps enforce a uniform style for all committers. Continuous integration will check this as well on every
+  pull request. There are useful tools in the nix-shell that help with checking this locally. You can run `postgrest-check` to do this manually but
+  we recommend adding it to `.git/hooks/pre-commit` as `nix-shell --run postgrest-check` to automatically check this before doing a commit.
+
+### Running Tests
+
+For instructions on running tests, see the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md#testing).

-## Issues
-
-For questions on how to use PostgREST, please use
-[GitHub discussions](https://github.com/PostgREST/postgrest/discussions).
-
-### Reporting an Issue
-
-* Make sure you test against the latest [stable release](https://github.com/PostgREST/postgrest/releases/latest)
-  and also against the latest [devel release](https://github.com/PostgREST/postgrest/releases/tag/devel).
-  It is possible we already fixed the bug you're experiencing.
-
-* Provide steps to reproduce the issue, including your OS version and
-  the specific database schema that you are using.
-
-* Please include SQL logs for issues involving runtime problems. To obtain logs first
-  [enable logging all statements](http://www.microhowto.info/howto/log_all_queries_to_a_postgresql_server.html),
-  then [find your logs](http://blog.endpoint.com/2014/11/dear-postgresql-where-are-my-logs.html).
-
-* If your database schema has changed while the PostgREST server is running,
-  [send the server a `SIGUSR1` signal](http://postgrest.org/en/latest/admin.html#schema-reloading) or restart it to ensure the schema cache
-  is not stale. This sometimes fixes apparent bugs.
-
-## Code
-
-We have a fully nix-based development environment with many tools for a smooth development workflow available.
-Check the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md) on how to set it up and use it.
-
-* All contributions must pass the tests before being merged. When
-  you create a pull request your code will automatically be tested.
-
-* All fixes or features must have a test proving the improvement.
-
-* All code must also pass a [linter](http://community.haskell.org/~ndm/hlint/) and [styler](https://github.com/jaspervdj/stylish-haskell)
-  with no warnings. This helps enforce a uniform style for all committers. Continuous integration will check this as well on every
-  pull request. There are useful tools in the nix-shell that help with checking this locally. You can run `postgrest-check` to do this manually but
-  we recommend adding it to `.git/hooks/pre-commit` as `nix-shell --run postgrest-check` to automatically check this before doing a commit.
-
-### Running Tests
-
-For instructions on running tests, see the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md#testing).
-
-### Structuring commits in pull requests
-
-To simplify reviews, make it easy to split pull requests if deemed necessary, and to maintain clean and meaningful history of changes, you will be asked to update your PR if it does not follow the below rules:
-
-* It must be possible to merge the PR branch into target using `git merge --ff-only`, ie. the source branch must be rebased on top of target.
-* No merge commits in the source branch.
-* All commits in the source branch must be self contained, meaning: it should be possible to treat each commit as a separate PR.
-* Commits in the source branch must contain only related changes (related means the changes target a single problem/goal). For example, any refactorings should be isolated from the actual change implementation into separate commits.
-* Tests, documentation, and changelog updates should be contained in the same commits as the actual code changes they relate to. An exception to this rule is when test or documentation changes are made in separate PR.
-* Commit messages must be prefixed with one of the prefixes defined in [the list used by commit verification scripts](https://github.com/PostgREST/postgrest/blob/main/nix/tools/gitTools.nix#L11).
-* Commit messages should contain a longer description of the purpose of the changes contained in the commit and, for non-trivial changes, a description of the changes themselves.

+PostgREST requires metadata from the database schema to provide a REST API that abstracts SQL details. One example of this is the interface for :ref:`resource_embedding`.

 Getting this metadata requires expensive queries. To avoid repeating this work, PostgREST uses a schema cache.

-~~~~~~~~~~
-
-PostgREST does not reload the schema cache for each notification when several ``NOTIFY pgrst`` events are generated quickly after one another.
-
-There are two cases to consider: when notifications are sent within a single transaction and when they are sent across multiple transactions.
-
-In the first case, PostgreSQL deduplicates identical ``NOTIFY`` events within the same transaction. This means that even if multiple ``NOTIFY pgrst`` statements are executed before a ``COMMIT``, only a single notification is delivered to PostgREST.
-
-In the second case, when notifications are sent from separate transactions in a short time span, PostgREST applies a debouncing mechanism to avoid excessive schema cache reloads.
-
-Instead of reloading the schema cache for each notification, events are grouped within a small time window of 100 milliseconds. The reload function is executed once immediately when the first notification is received and once more after the burst of events settles, resulting in at most two executions within that time window.

Wolfgang Walther	d30abd99ae	chore: remove Paths_postgrest module The dependency on it was removed in #3608 already, but we forgot to remove it from postgrest.cabal, which caused it to still be built.

Joel JakobssonandWolfgang Walther	73d335e976	fix(openapi): respect function volatility for GET methods The OpenAPI specification was incorrectly exposing GET methods for VOLATILE functions, even though such functions properly reject GET requests at runtime with "405 Method Not Allowed". This created a mismatch between the advertised API specification and the actual runtime behavior. VOLATILE functions should only be callable via POST since they may have side effects, while STABLE and IMMUTABLE functions can safely be called via GET since they don't modify database state. Fix by checking the pdVolatility field in makeProcPathItem() and only including GET methods in the OpenAPI PathItem for non-volatile functions. The runtime behavior was already correct; this fixes only the OpenAPI documentation generation.	2025-07-07 17:28:07 +02:00

Wolfgang Walther	087b9ecca1	ci: fix loadtest job on stable branches Previously, the loadtest would always compare against main and the latest tag. This meant a loadtest running on the v13 release branch, would compare to a future version of both. This is not useful, and also not supported by `postgrest-loadtest-against`, which recently introduced a change on `main`, that now breaks the tests on the back branches. With this change, the loadtest will always run against the current target branch of a PR, so against the v13 branch for a PR against v13, for example. Also, it will compare against the latest released tag for that branch. Thus, when running this for v12, it will test against the v12 branch and the v12.2.12 tag.	2025-06-26 09:44:01 +00:00
