package test

#
import future.keywords.every

p {
    1 in []
}

importing every implies importing in, it's probably related to that.

opa fmt f.rego gives this 💥

ast+topdown+planner: allow for mocking built-in functions via "with" (open-policy-agent#4540)

With this change, we can replace calls to built-in functions via `with`. The replacement
can either be a value -- which will be used as the return value for every call to the
mocked built-in -- or a reference to a non-built-in function -- when the results need
to depend on the call's arguments.

Compiler, topdown, and planner have been adapted in this change. The included
docs changes describe the replacement options further.

Fixes first part of open-policy-agent#4449. (Missing are non-built-in functions as mock targets.)

cmd/capabilities: expose capabilities through CLI (open-policy-agent#4588)

There is a new command argument "capabilities". With this, it is
possible to print the current capabilities version, show all
capabilities versions & print any capabilities version, without the need
of a file. Moreover, for the other commands which use the --capabilities
flag, it is possible to give only the version number, without specifying
a file. However, there are no breaking changes for those who use the
capabilities file as an input for the flag. Unit tests were also
written, in order to test the new argument and the changes made in ast.

format,eval: don't use source locations when formatting PE output (open-policy-agent#4611)

* format: allow ignoreing source locations
* cmd/eval: format disregarding source locations for partial result

Before, we'd see this output:
```
$ opa eval -p -fsource 'time.clock(input.x)==time.clock(input.y)'
# Query 1
time.clock(time.clock(input.x), input.y)
```

Now, we get the proper answer: `time.clock(input.y, time.clock(input.x))`.

Note that it's a _display_ issue; the JSON output of PE has not been affected.

# This is the commit message open-policy-agent#14:

status: Remove activeRevision label on all but one metric (open-policy-agent#4600)

Having one activeRevision label on each of the prometheus metrics emitted
by the status plugin has proven to be problematic with a large number of
bundles. So with this change,

1. we keep the activeRevision label (just on) the last_success_bundle_activation metric.
2. the gauge gets reset, so we only keep the last active_revision (instead of keeping
   them all and therefore avoiding the situation where the /metrics output grows indefinitely)

topdown/net: require prefix length for IPv6 in net.cidr_merge (open-policy-agent#4613)

There are no default prefixes in IPv6, so if an IPv6 without a prefix is fed into
net.cidr_merge, we'll return a non-halt error now.

Before, we'd fail in various ways if a prefix-less IPv6 was fed into
`net.cidr_merge`. With only one, we'd return `[ "<nil>" ]`, with two,
we'd panic.

bundle/status: Include bundle type in status information

OPA has support for Delta Bundles. The status object already
contains valuable information such as last activation timestamp but
does not specify if the bundle was a canonical snapshot or delta.

This change updates the bundle.Status object to include the
bundle type string: either "snapshot" or "delta". This can be useful
for status endpoints to differentiate between the bundle types.

ast+topdown+planner: replacement of non-built-in functions via 'with' (open-policy-agent#4616)

Follow-up to open-policy-agent#4540

We can now mock functions that are user-defined:

    package test

    f(_) = 1 {
        input.x = "x"
    }
    p = y {
        y := f(1) with f as 2
    }

...following the same scoping rules as laid out for built-in mocks.
The replacement can be a value (replacing all calls), or a built-in,
or another non-built-in function.

Also addresses bugs in the previous slice:
* topdown/evalCall: account for empty rules result from indexer
* topdown/eval: capture value replacement in PE could panic

Note: in PE, we now drop 'with' for function mocks of any kind:

These are always fully replaced in the saved support modules, so
this should be OK.

When keeping them, we'd also have to either copy the existing definitions
into the support module; or create a function stub in it.

downloader: support for downloading bundles from an OCI registry (open-policy-agent#4558)

Initial support for open-policy-agent#4518.

Configuration uses the 'services' config for registries, via the "type: oci" field.
Bundles configured to pull from that service will then use OCI.

```
services:
  ghcr-registry:
    url: https://ghcr.io
    type: oci
bundles:
  authz:
    service: ghcr-registry
    resource: ghcr.io/${ORGANIZATION}/${REPOSITORY}:${TAG}
    persist: true
    polling:
      min_delay_seconds: 60
      max_delay_seconds: 120
persistence_directory: ${PERSISTENCE_PATH}
```

Service credentials are supported: if you want to pull from a private registry,
use
```
services:
  ghcr-registry:
    url: https://ghcr.io
    type: oci
    credentials:
      bearer:
        token: ${GH_PAT}
```

If no `persistence_directory` is configured, the data is stored in a directory under /tmp.

See docs/devel/OCI.md for manual steps to test this feature with some
OCI registry (like ghcr.io).
