Revision history for kiroku-metrics

0.1.0.8 -- 2026-08-16

Other Changes

• Requires kiroku-store ^>=0.8, which adds the TransientTransactionFailure constructor to StoreError. The fixed subscription metrics schema does not match on StoreError, so no source change was required and no kiroku-metrics API or runtime behavior changed.

0.1.0.7 -- 2026-08-15

Other Changes

• Built with ghc-options: -Wall -Werror=incomplete-patterns, matching every other package in the repository. The fixed subscription metrics schema's KirokuEvent match was already exhaustive, so no source change was required and no kiroku-metrics API or runtime behavior changed.

0.1.0.6 -- 2026-08-13

Other Changes

• Requires kiroku-store ^>=0.7. The fixed subscription metrics schema explicitly ignores replay-history retention lifecycle events while composed event passthrough still receives them; no kiroku-metrics API changed.

0.1.0.5 -- 2026-08-12

Other Changes

• Requires kiroku-store ^>=0.6, whose exported Store effect now offers the visible global head position read. No kiroku-metrics API or runtime behavior changed.

0.1.0.4 -- 2026-08-11

Other Changes

• The collector consumes the new subscription checkpoint-resolution lifecycle event and records its durable position as the subscription checkpoint gauge. It also remains exhaustive for typed missing-checkpoint startup refusal.
• Requires kiroku-store ^>=0.5. No kiroku-metrics API changed.

0.1.0.3 -- 2026-08-09

Bug Fixes

• Corrected the kiroku_events_appended_total Prometheus HELP text: the value is the current opaque global position and is not guaranteed to be dense.

Other Changes

• Requires kiroku-store ^>=0.4, whose exported Store effect now supports durable subscription checkpoint inventory reads. No kiroku-metrics API changed.
• Added a PVP upper bound to the shipped example's internal kiroku-test-support dependency. Version 0.1.0.2 was tagged but not published after cabal check found the missing bound.

0.1.0.1 -- 2026-07-11

Other Changes

• Relaxed dependency bounds to kiroku-store ^>=0.3 and kiroku-cli ^>=0.2. No change to kiroku-metrics' own API or behavior.

0.1.0.0 -- 2026-06-15

First release. A sister package to kiroku-store that exposes operational metrics and event streams over HTTP without pulling a web framework into the core library.

New Features

• In-process metrics collector and JSON-encodable snapshot type.
• HTTP endpoints serving metrics as JSON, Prometheus exposition format, and a health check.
• WebSocket channel for streaming live metrics and events out of a running store.
• Live subscription-status endpoint over HTTP, with a CLI remote client.
• Runnable, self-verifying kiroku-metrics-example and a user guide.
