v0.4.3

This release includes various bug fixes, including fixing some crashes. It also fixes a memory leak that would cause long-running servers to OOM (see #1418). It also now supports Go 1.18.

It also fixes various builtin extensions.

This release also makes a lot of preparations for the upcoming comprehension rework, which will allow us to do all kinds improvements and performance enhancements.

As a reminder: users can register their projects with unity, our regression and performance testing setup. unity is used to ensure that a project's CUE evaluations do not unexpectedly stop working, or regress in terms of performance. unity continues to catch multiple issues with each release. Adding your project to unity not only guarantees that we will not break your tests (if we do, we will work with you to fix your CUE code), but it also helps to improve the quality of each CUE release. We are in the process of adding support for adding private projects to unity.

Thank you to @benmoss, @cuichenli, @danbison, @emcfarlane, @eonpatapon, @jared-gs, @jdreaver, @jlongtine, @mattmoor, @mvdan, @oncilla, @roidelapluie, @slewiskelly, @xinau, and @yannk for contributing to this release!

Language changes

This release removes all remaining support for quoted identifiers. Although this hasn't been supported for a while, there were still parts of the code that handled them, resulting in cryptic error messages.

Core evaluator

This release sees an overall improvement in error location reporting. These changes are quite substantial but largely, aside from a few resulting bug fixes, do not alter behavior.

Builtins

net

Add CIDR range verification function.

regexp

Add ReplaceAll and ReplaceAllLiteral

time

Fixes a hermeticity issues where a local time zone may be selected. Added FormatString to ultimately replace Format, where Format will first have to be deprecated.

Add FormatString, FormatDuration and Split

tool/file

Add MkdirTemp, RemoveAll

tool/http

Add Support for TLS settings.

This release also makes a lot of preparations for the upcoming comprehension rework, which will allow us to do all kinds improvements and performance enhancements.

As a reminder: users can register their projects with unity, our regression and performance testing setup. unity is used to ensure that a project's CUE evaluations do not unexpectedly stop working, or regress in terms of performance. unity continues to catch multiple issues with each release. Adding your project to unity not only guarantees that we will not break your tests (if we do, we will work with you to fix your CUE code), but it also helps to improve the quality of each CUE release. We are in the process of adding support for adding private projects to unity.

Language changes

This release removes all remaining support for quoted identifiers. Although this hasn't been supported for a while, there were still parts of the code that handled them, resulting in cryptic error messages.

Core evaluator

This release sees an overall improvement in error location reporting. These changes are quite substantial but largely, aside from a few resulting bug fixes, do not alter behavior.

Builtins

net

Add CIDR range verification function.

regexp

Add ReplaceAll and ReplaceAllLiteral

time

Fixes a hermeticity issues where a local time zone may be selected. Added FormatString to ultimately replace Format, where Format will first have to be deprecated.

Add FormatString, FormatDuration and Split

tool/file

Add MkdirTemp, RemoveAll

tool/http

Add Support for TLS settings.

v0.4.2

This patch release largely focuses on bug fixes, but also includes some additions to the cmd/cue cmd tooling layer and builtins. Some of the bug fixes were identified as part of preparing for an upcoming CUE talk at FOSDEM.

Thank you to @brandonbloom, @eonpatapon, @obowersa and @seh for contributing to this release!

Core evaluator

A number of bug fixes relating to edge cases of CUE evaluation. Notably, 1374dc9 fixes some subtle bugs where fields can be missed if patterns are inserted too late.

0aaf4c6 disallows _ as a field label, fixing a bug where the following CUE was previously accepted as valid:

_: 5

This now results in:

cannot use _ as label:
    ./x.cue:1:1

Tooling layer (cmd/cue cmd)

@eonpatapon added Mkdir, MkdirAll to pkg/tool/file. #1502 was raised as a follow-up, a wider review of how the pkg/… API needs to change pre v1.

Spec

@seh contributed to the "Declarations and scope" section, clarifying that top-level let identifiers are scoped to the containing file block.

cmd/cue

@slewiskelly highlighted a regression introduced as far back as aaf6e84 where cmd/cue is used to validate data using a schema. In this regression, CUE inadvertently marks the failures as "fatal", instead of "incomplete" (that is, could be satisfied by making a value more concrete). 04812bf disables schema checking for now whilst we consider a more precise solution.

Builtins

Both pkg/encoding/yaml and pkg/encoding/json now support UnmarshalStream.

Changelog

• 6bc922c tools/trim: prevent nil-pointer panic
• 9aeaf70 pkg/encoding/json: implement UnmarshalStream
• 480b28b pkg/encoding/yaml: implement UnmarshalStream
• 880863a encoing/json: made independent of pkg/encoding/json
• 802a852 cmd/cue/cmd: only consider "kind" field for known tasks
• bd3b6ea cmd/cue: add newline between imported objects
• 04812bf cmd/cue: fix spurious errors
• 2fe5251 doc/ref/spec.md: clarify scope of top-level let ID
• 556f57f doc/tutorial: fix typo in 55_defs.txt
• f0d03f3 cue/ast: fix typo in docstring
• f29b460 cmd/cue/cmd: remove stale reference to ::
• 50d69c9 all: prepare for private repository support in unity
• 5581d64 doc: fix heading level for div et al builtins
• 45c54f8 pkg/tool/file: add Mkdir, MkdirAll
• 34c4f9c Revert "pkg/tool/file: add Mkdir, MkdirAll"
• 23cc102 pkg/tool/file: add Mkdir, MkdirAll
• 0aaf4c6 internal/core: disallow _ as field label
• c1bf550 internal/core/eval: dereference indirections earlier
• 9f6a40e internal/core/adt: zero-value feature means "invalid"
• 1374dc9 internal/core/adt: single place for inserting matched patterns

v0.4.1

After an extended break following CUE's migration to cue-lang/cue and multiple pre-releases, the v0.4.1 release mainly focuses on bug fixes. We also renew our pledge to in future release smaller changes more frequently on our way to language stability.

Thank you to @chai2010, @yujunz, @caarlos0, @hrvolapeter, @slewiskelly, @antong, @mvdan, @ameowlia and @palmamartin for contributing to this release!
