NOTES:

  • The minimum version of Go required to build the OPA module is 1.22

We are excited to announce OPA 1.0, a milestone release consolidating an improved developer experience for the future of Policy as Code. The release makes new functionality designed to simplify policy writing and improve the language's consistency the default.

Changes to Rego in OPA 1.0

Below we highlight some key changes to the defaults in OPA 1.0:

  • Using if for all rule definitions and contains for multi-value rules is now mandatory, not just when using the rego.v1 import.
  • Other new keywords (every, in) are available without any imports.
  • Previously requirements that were only run in "strict mode" (like opa check --strict) are now the default. Duplicate imports and imports which shadow each other are no longer allowed.
  • OPA 1.0 comes with a range of backwards compatibility features to aid your migrations, please see the v0 compatibility guide
    if you must continue to support v0 Rego.

Read more about the OPA 1.0 announcement here on our blog.

Following are other changes that are included in OPA 1.0.

Improvements to memory allocations

PRs #7172, #7190, #7193, #7165, #7168, #7191 & #7222 together improve the memory performance of OPA. Key strategies
include reusing pointers and optimizing array and object operations, minimizing intermediate object creation, and using sync.Pool
to manage memory-heavy operations. These changes cumulatively greatly reduced the number of allocations and improved
evaluation speed by 10-20%. Additional benchmarks highlighted significant memory and speed improvements in custom
function evaluation.

Wrap http.RoundTripper for SDK users

PR #7180 adds an EvalHTTPRoundTrip EvalOption and query-level WithHTTPRoundTrip option.
Both use a new function type which converts an http.Transport configured by topdown to an http.RoundTripper.
This supports use cases requiring the customization of the http.send built in behavior.

Authored by @evankanderson.

Improvements to scientific notation parsing in units.parse

PR #7147 extends the behaviour of extractNumAndUnit to support
scientific notation values. This means values such as 1e3KB can now be handled by this function.

Authored by @berdanA.

Support customized buckets bundle_loading_duration_ns metric

PR #7156 extends OPA’s Prometheus configuration to allow the
setting of user defined buckets for metrics. This aids when debugging the loading of slow bundles.

Authored by @jwu730-1.

Test suite performance improvements

PR #7126 updates tests to improve performance. Topdown and storage/disk/
tests now run around 50% and 75% faster respectively.

This release contains a mix of features, performance improvements, and bugfixes.

Optimized read mode for OPA's in-memory store (#7125)

A new optimized read mode has been added to the default in-memory store, where data written to the store is eagerly converted
to AST values (the data format used during evaluation). This removes the time spent converting raw data values to AST
during policy evaluation, thereby improving performance.

The memory footprint of the store will increase, as processed AST values generally take up more space in memory than the
corresponding raw data values, but overall memory usage of OPA might remain more stable over time, as pre-converted data
is shared across evaluations and isn't recomputed for each evaluation, which can cause spikes in memory usage.

This mode can be enabled for opa run, opa eval, and opa bench by setting the --optimize-store-for-read-speed flag.

More information about this feature can be found here.

v0.69.0

This release contains a mix of features, bugfixes and necessary tooling and test changes required to support the upcoming OPA 1.0 release.

Inter-Query Value Cache (#6908)

OPA now has a new inter-query value cache added to the SDK. It is intended to be used for values that are expensive to compute and can be reused across multiple queries. The cache can be leveraged by built-in functions to store values that otherwise aren't appropriate for the existing inter-query cache; for instance when the entry size isn't an appropriate or primary limiting factor for cache eviction.

The default size of the inter-query value cache is unbounded, but can be configured via the caching.inter_query_builtin_value_cache.max_num_entries configuration field. OPA will drop random items from the cache if this limit is exceeded.

The cache is used by the regex and glob built-in functions, which previously had individual, non-configurable caches with a max entry size of 100 each.

Currently, the cache is only exercised when running OPA in server mode (ie. opa run -s). Also this feature is unsupported for WASM.

Breaking Changes

entrypoint annotation implies document scope (#6798)

The entrypoint annotation's scope requirement has changed from rule to document (https://github.com/open-policy-agent/opa/issues/6798). Furthermore, if no scope annotation is declared for a METADATA block preceding a rule, the presence of an entrypoint annotation with a true value will assign the block a document scope, where the rule scope is otherwise the default.

In practice, a rule entrypoint always point to the entire document and not a particular rule definition. The previous behavior was a bug, and one we've now addressed.

  • opa exec: This command never supported "pretty" formatting (--format=pretty or -f pretty), only json. Passing pretty is now invalid. (#6923) authored by @srenatus
    Note that the flag is now unnecessary, but it's kept so existing calls like opa exec -fjson ... remain valid.

Security Fix: CVE-2024-8260 (#6933)

This release includes a fix where OPA would accept UNC locations on Windows. Reading those could leak NTLM hashes.
The attack vector would include an adversary tricking the user in passing an UNC path to OPA, e.g. opa eval -d $FILE.
UNC paths are now forbidden. If this is an issue for you, please reach out on Slack or GitHub issues.

Breaking Change

Request Body Size Limits

OPA now automatically rejects very large requests (#6868) authored by @philipaconrad.
Requests with a Content-Length larger than 128 MB uncompressed, and gzipped requests with payloads that decompress to
larger than 256 MB will be rejected, as part of hardening OPA against denial-of-service attacks. Previously, a large
enough request could cause an OPA instance to run out of memory in low-memory sidecar deployment scenarios, just from
attempting to read the request body into memory.

These changes allow improvements in memory usage for the OPA HTTP server, and help OPA deployments avoid some accidental out-of-memory situations.

For most users, no changes will be needed to continue using OPA. However, to control this behavior, two new configuration
keys are available: server.decoding.max_length and server.decoding.gzip.max_length. These control the max size in
bytes to allow for an incoming request payload, and the maximum size in bytes to allow for a decompressed gzip request payload, respectively.

Here's an example OPA configuration using the new keys:

# Set max request size to 64 MB and max gzip size (decompressed) to be 128 MB.
server:
  decoding:
    max_length: 67108864
    gzip:
      max_length: 134217728

Breaking changes

A new IsSetStmt statement has been added to the intermediate representation (IR).
This is a breaking change for custom IR evaluators, which must interpret this statement in IR plans generated by this OPA version and later.
No actions are required for Wasm users, as long as Wasm modules are built by this OPA version or later.

  • ci: Pin GitHub Actions macos runner version. The architecture of the GitHub Actions Runner macos-latest was changed from amd64 to arm64 and as a result darwin/amd64 binary wasn't released (#6720) authored by @suzuki-shunsuke
  • plugins/discovery: Update comparison logic used in the discovery plugin for handling overrides. This fixes a panic that resulted from the comparison of uncomparable types (#6723) authored by @ashutosh-narkar

NOTES:

  • The minimum version of Go required to build the OPA module is 1.21

This release contains a mix of features, a new builtin function (json.marshal_with_options()), performance improvements, and bugfixes.

Breaking Change

Bootstrap configuration overrides Discovered configuration

Previously if Discovery was enabled, other features like bundle downloading and status reporting could not be configured manually.
The reason for this was to prevent OPAs being deployed that could not be controlled through discovery. It's possible that
the system serving the discovered config is unaware of all options locally available in OPA. Hence, we relax the configuration
check when discovery is enabled so that the bootstrap configuration can contain plugin configurations. In case of conflicts,
the bootstrap configuration for plugins wins. These local configuration overrides from the bootstrap configuration are included
in the Status API messages so that management systems can get visibility into the local overrides.

In general, the bootstrap configuration overrides the discovered configuration. Previously this was not the case for all
configuration fields. For example, if the discovered configuration changes the labels section, only labels that are
additional compared to the bootstrap configuration are used, all other changes are ignored. This implies labels in the
bootstrap configuration override those in the discovered configuration. But for fields such as default_decision, default_authorization_decision,
nd_builtin_cache, the discovered configuration would override the bootstrap configuration. Now the behavior is more consistent
for the entire configuration and helps to avoid accidental configuration errors. (#5722) authored by @ashutosh-narkar

Add rego_version attribute to the bundle manifest

A new global rego_version attribute is added to the bundle manifest, to inform the OPA runtime about what Rego version (v0/v1) to
use while parsing/compiling contained Rego files. There is also a new file_rego_versions attribute which allows individual
files to override the global Rego version specified by rego_version.

When the version of the contained Rego is advertised by the bundle through this attribute, it is not required to run OPA with the
--v1-compatible (or future --v0-compatible) flag in order to correctly parse, compile and evaluate the bundle's modules.

A bundle's rego_version attribute takes precedence over any applied --v1-compatible/--v0-compatible flag. (#6578) authored by @johanfylling

Runtime, Tooling, SDK

  • compile: Fix panic from CLI + metadata entrypoint overlaps. The panic occurs when opa build was provided an entrypoint from both a CLI flag, and via entrypoint metadata annotation. (#6661) authored by @philipaconrad
  • cmd/deps: Improve memory footprint and execution time of deps command for policies with high dependency connectivity (#6685) authored by @johanfylling
  • server: Keep default decision path in-sync with manager's config (#6697) authored by @ashutosh-narkar
  • server: Remove unnecessary AST-to-JSON conversions (#6665) and (#6669) authored by @koponen-styra
  • sdk: Allow customizations of the plugin manager via SDK (#6662) authored by @xico42
  • sdk: Fix issue where active parser options aren't propagated to module reload during bundle activation resulting in errors while activating bundles with v1 syntax (#6689) authored by @xico42
  • plugins/rest: Close response body in OAuth2 client credentials flow (#6708) authored by @johanneslarsson

Topdown and Rego

  • ast: Import rego.v1 in v0 support modules when applicable (#6450) authored by @johanfylling
  • rego: Set query Rego version from configured imports (#6701) authored by @johanfylling
  • topdown: New json.marshal_with_options() builtin for indented/"pretty-printed" and/or line-prefixed JSON (#6630) authored by @sean-r-williams

Miscellaneous

  • go.{mod,sum}: Update the go stanza of OPA's go.mod to go 1.21. OPA, used as Go dependency, requires at least go 1.21, and thus works with all officially supported Go versions (1.21.x and 1.22.x) (#6678) authored by @srenatus
  • ci: Update Github Actions for Node 20. This change updates the upload-artifact and download-artifact Github actions to the latest version (v4) (#6670) authored by @philipaconrad
