ci(rust): bump jaq-core from 2.2.1 to 3.1.0

[dependabot]

Bumps jaq-core from 2.2.1 to 3.1.0.

Release notes

Sourced from jaq-core's releases.

3.1

This release adds support for jq's input_filename filter --- thanks to @​a-n-d-r-e-w-l 01mf02/jaq#432! Furthermore, at places where jaq accepted filters like .a["b"], it now also accepts (equivalent) filters such as .a.["b"] (note the added dot after .a). 01mf02/jaq#423 Finally, this release corrects the indexing of arrays with an empty array, which previously panicked 01mf02/jaq#439. Thanks to @​leeewee for spotting this!

API

The biggest change in this release is that calls to halt in jq filters can now be handled by users of the jaq API, instead of forcing a termination of the process. Thanks to @​a-n-d-r-e-w-l 01mf02/jaq#433! This has a few implications:

• The signature of jaq_all::data::run had to be changed, resulting in a new major version of jaq-all.
• To preserve semantic versioning stability guarantees, the jaq_core::unwrap_valr function still terminates the current process if halt is called, but only if the std feature is enabled --- otherwise, unwrap_valr panics! You need to take action to prevent panics if all of the following conditions hold:
  1. you use jaq_core::unwrap_valr,
  2. you have disabled the std feature in jaq_core, and
  3. you run filters that may call halt.

Furthermore, this version makes it possible to clone definitions, which can speed up compiling many different jq filters. 01mf02/jaq#430

3.0

jaq is a jq clone with focus on correctness, speed, and simplicity.

The most outstanding change in jaq 3.0 is its multi-format support, allowing you to read and write several data formats such as YAML, CBOR, TOML, XML, CSV, TSV, and of course JSON. That means that among others, jaq can convert data from one format into another, while transforming data with a jq filter. This effectively makes it into a "Pandoc for structured data". Achieving this has been the main focus of the NLnet-founded "Polyglot jaq" project, which has been successfully finished. A huge thanks to NLnet for supporting jaq and, more generally, free software!

Other large user-facing changes include:

• Manual: jaq now has a full jq and jaq reference manual. This was a monumental effort into which I poured a lot of love, and I hope that you enjoy reading it as much as I enjoyed putting easter eggs into it. Bonus: You also get a man page. (For package maintainers: Man page build instructions can be found in docs/README.md.)
• Byte strings: You can now read strings that contain arbitrary contents, including invalid UTF-8 sequences. (When a string is read from a file, this takes only constant time, thanks to memory mapping.) You can then mark these strings as byte strings via tobytes, allowing you to index/slice them in constant time. This allows you to process arbitrary binary data efficiently with jaq --- as proof of concept, I implemented a little TAR decoder.
• Arbitrary values as object keys: Where jq supports only strings as object keys, jaq supports arbitrary values as object keys.
• Compatibility improvements: Although this release adds many new features to jaq that do not exist in jq, this release still increases compatibility with jq. For example, jaq now supports path/1 and many other path-related filters.

API:

• New jaq-all crate for easier "batteries-included" jaq usage
• Passing arbitrary data to native filters
• Optional thread-safe jaq_json::Val when enabling the sync feature, allowing for multithreaded usage of values, e.g. running multiple filters in parallel on the same value

Changes since 3.0-gamma:

• Support CSV/TSV, initiated by @​jack-faller #405
• Speed up length of text strings #417
• Update to codesnake 0.3 #413
• Store TermId as reference in Exn #411

See the release notes for alpha, beta, and gamma for more details on all changes since jaq 2.3.

DEFER — Blocked by PR #4 (jaq-std upgrade). This PR cannot land in isolation.

Issue

This bumps jaq-core 2.2.1 → 3.1.0, but the dependency tree is broken:

• jaq-json 1.1.3 pins jaq-core 2.2.1
• jaq-std 2.1.2 pins jaq-core 2.2.1
• PR ci(rust): bump jaq-core from 2.2.1 to 3.1.0 #15 tries to use jaq-core 3.1.0

→ Cargo sees both 2.2.1 and 3.1.0 in the dependency graph. Build fails.

Root Cause: Sequencing

Both jaq-core and jaq-std are major version bumps (2→3) in the jaq ecosystem. PR #4 (jaq-std 3.0.1) must land first to resolve jaq-std's dependency pin on jaq-core 2.x. Only then can PR #15 work.

Current state: Both failing checks, 30+ days open, rebasing disabled.

Action

1. Re-enable rebasing on PR ci(rust): bump jaq-std from 2.1.2 to 3.0.1 #4 and land it to main after passing checks
2. Rebase PR ci(rust): bump jaq-core from 2.2.1 to 3.1.0 #15 against the updated main (will resolve jaq-std/jaq-core constraint)
3. Re-run CI on PR ci(rust): bump jaq-core from 2.2.1 to 3.1.0 #15

Quality Note

jaq-core 3.1.0 is solid: halt handling improvements, API safety enhancements, bug fixes. The blocker is purely sequencing, not version quality.
