Subject: [PATCH 01/15] Migrate from Sidekiq to ActiveJob
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace all Sidekiq workers with ActiveJob jobs
- Convert RatesWorker concern to RatesJob concern
- Use limits_concurrency for Solid Queue instead of sidekiq-unique-jobs
- Replace perform_async with perform_later
- Update all model and controller references
- Create new job spec files, remove old worker specs

Jobs converted:
- DirectionsRatesJob
- CurrencyRatesJob
- ExternalRatesBatchJob
- ExternalRateSaverJob
- ExchangeRateUpdaterJob
- CreateHistoryIntervalsJob
- CbrRatesJob, CbrAvgRatesJob
- BinanceRatesJob, ExmoRatesJob, BybitRatesJob
- BitfinexRatesJob, CryptomusRatesJob
- GarantexioRatesJob, FfFixedRatesJob, FfFloatRatesJob

From 3b865c89f2d2dac25df10a2db5a01545ea1ab430 Mon Sep 17 00:00:00 2001
From: Danil Pismenny <dapi@users.noreply.github.com>
Date: Mon, 1 Dec 2025 15:46:12 +0300
Subject: [PATCH 02/15] Fix limits_concurrency lambda to accept job argument
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Solid Queue passes the job instance to the key lambda, but our lambdas
expected no arguments. Changed from `-> { key }` to `->(_job) { key }`.

Subject: [PATCH 03/15] Replace sidekiq dependency with solid_queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace sidekiq gem with solid_queue in gemspec
- Update lib/gera.rb to require solid_queue instead of sidekiq
- Remove sidekiq/testing from spec_helper, use ActiveJob test adapter
- Remove incorrect SolidQueue::Job::Concurrency include (engine auto-includes)

SolidQueue's engine automatically includes ActiveJob::ConcurrencyControls
which provides the limits_concurrency method for concurrency control.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Major version bump due to migration from Sidekiq to ActiveJob.

Breaking changes:
- All workers renamed to jobs (e.g., ExmoRatesWorker → ExmoRatesJob)
- Sidekiq dependency replaced with solid_queue
- Worker concerns renamed to job concerns (RatesWorker → RatesJob)

Subject: [PATCH 07/15] Fix open-uri deprecation: use Net::HTTP and URI.open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace `open(url).read` with `Net::HTTP.get(uri)` in ExmoFetcher
- Replace `open uri` with `URI.open(uri)` in CbrRatesJob
- Centralize require 'open-uri' and 'net/http' in lib/gera.rb
- Remove duplicate requires from individual files
- Update ExmoFetcher spec to mock Net::HTTP.get

In Ruby 3.0+, Kernel#open with URI strings requires open-uri and
explicit URI.open call. This change prevents ENOENT errors when
fetching external rate APIs.

Refactored both fetchers to use RestClient directly instead of inheriting
from PaymentServices::Base::Client (which is defined in the host app).

Subject: [PATCH 10/15] Fix limits_concurrency lambda arity for SolidQueue
 recurring tasks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change lambda from ->(_job) to ->(*) in all jobs to handle
recurring tasks without arguments. SolidQueue calls the key lambda
with *arguments (job arguments), and for recurring tasks without
args: in config/recurring.yml, this passes 0 arguments.

Bump version to 1.2.0

Fixes: alfagen/mercury#1651

 DirectionRatesRepository#build_matrix

Content-Transfer-Encoding: 8bit

Optimization for mercury issue #1691:
- DirectionRate contains pre-calculated rate_percent (commission)
- ExchangeRate contains is_enabled?, auto_rate? (direction settings)
- Instead of calling er.final_rate_percents (4 DB queries each time)
  use dr.rate_percent (already saved, 0 queries)
- includes loads all exchange_rates in 1 additional query

Before: N×M × 4 queries when displaying rates matrix
After: 2 queries (direction_rates + exchange_rates)

Subject: [PATCH 12/15] Use warning instead of error for missing currency rates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When currency rate cannot be calculated for a pair, log a warning
instead of raising an error and notifying Bugsnag. This is expected
behavior when rate data is unavailable from sources.

- Replace raise Error with logger.warn and early return
- Change RateSource::RateNotFound from error to warn level
- Remove unused Error class
- Add tests for graceful handling

Fixes alfagen/mercury#1708

Subject: [PATCH 14/15] Add enable_direction_rate_history_intervals config
 option

Allow disabling direction_rate_history_intervals creation to save disk space
(~42GB on production). The table is only used for admin charts.

- Add enable_direction_rate_history_intervals config (default: true)
- Skip saving direction_rate_history_intervals when disabled
- Add helper method for controller to check status
- Show warning banner in view when collection is disabled

Subject: [PATCH 15/15] feat: Add autorate calculators with Manul API support

Adapts PR #71 (position-aware autorate) for current master:
- Add AutorateCalculators::Legacy and PositionAware with Strategy pattern
- Use Manul API instead of BestChange::Service for external rates
- Use ActiveJob (perform_later) instead of Sidekiq (perform_async)
- Add calculator_type column to exchange_rates for selecting algorithm
- Add our_exchanger_id and anomaly_threshold_percent config options

The PositionAware calculator prevents "jumping over" positions above
the target range, with adaptive GAP and anomaly protection.

Closes #69
