> camel-git - the consumer ignores the scheduler and error handler options:

> Key: CAMEL-26651
> URL: https://issues.apache.org/jira/browse/CAMEL-26651
> Project: Camel
> Issue Type: Bug
> Components: camel-git
> Affects Versions: 4.10.0, 4.14.9, 4.18.5, 4.22.2, 4.23.0
> Reporter: Federico Mariani

> h3. Problem
> Since CAMEL-19665 (first released in 4.10.0), {{GitEndpoint}} extends
> {{ScheduledPollEndpoint}}, so the catalog and the documentation list the
> scheduler options for the git consumer. But {{GitEndpoint.createConsumer}}
> never calls {{configureConsumer(consumer)}}: it returns {{new
> GitCommitConsumer/GitTagConsumer/GitBranchConsumer(this, processor)}}
> directly
> ({{components/camel-git/src/main/java/org/apache/camel/component/git/GitEndpoint.java}}
> lines 158-168, main commit 7978db3d42dd).
> As a result, nothing copies the endpoint options to the consumer:
> * {{ScheduledPollEndpoint.doConfigureConsumer}} options: delay, initialDelay,
> startScheduler, greedy, backoffErrorThreshold, backoffIdleThreshold,
> backoffMultiplier, repeatCount, pollStrategy, runLoggingLevel,
> scheduledExecutorService, sendEmptyMessageWhenIdle, timeUnit, useFixedDelay,
> scheduler and schedulerProperties.
> * {{DefaultEndpoint.configureConsumer}} options: bridgeErrorHandler and
> exceptionHandler.
> The URI accepts these options and they are ignored without any warning. The
> consumer always polls with the {{ScheduledPollConsumer}} defaults:
> initialDelay 1000 ms and delay 500 ms.
> The source is the same in camel-4.10.0, 4.14.9, 4.18.5, 4.22.2, 4.23.0 and
> main: none of them calls {{configureConsumer}}. In 4.8.0 the endpoint was a
> {{DefaultEndpoint}}, so bridgeErrorHandler and exceptionHandler were already
> ignored there, but the scheduler options did not exist yet.
> h3. How to reproduce
> Measured on main with a JUnit test, against a JGit repository in a temporary
> directory:
> {code:java}
> GitEndpoint ep = context.getEndpoint("git:" + dir
> +
> "?type=commit&branchName=master&delay=60000&initialDelay=5000&startScheduler=false",
> GitEndpoint.class);
> assertEquals(60000, ep.getDelay());
> GitCommitConsumer consumer = (GitCommitConsumer) ep.createConsumer(e -> { });
> assertEquals(500, consumer.getDelay()); // not 60000
> assertEquals(1000, consumer.getInitialDelay()); // not 5000
> assertTrue(consumer.isStartScheduler()); // not false
> {code}
> Output: {{endpoint delay=60000 initialDelay=5000 startScheduler=false,
> consumer delay=500 initialDelay=1000 startScheduler=true}}.
> In an earlier run of the same test, {{startScheduler=false}} was set only on
> the URI. The scheduler still polled in the background, at the same time as
> the test's own {{poll()}} calls: more commits were delivered than the
> repository had.
> For comparison, from the source: {{GitHub2Endpoint.createConsumer}} in
> camel-github2 does call {{configureConsumer}}.
> h3. Proposed change
> * Call {{configureConsumer(consumer)}} in {{GitEndpoint.createConsumer}}
> before returning, as the other {{ScheduledPollEndpoint}} components do.
> * Add a test that sets delay, initialDelay, startScheduler and
> bridgeErrorHandler, and checks them on the consumer.
> * Raising the default delay of the git consumer would be a separate decision:
> every idle poll walks the whole history of the branch. It was measured at 720
> ms per idle poll for 32k commits, growing about 3.4 times for each doubling
> of the commit count.
> h3. Impact / upgrade
> * No default value changes. Routes that set these options get what they
> configured: for example, {{delay=60000}} now really polls once a minute, and
> {{bridgeErrorHandler=true}} now applies.
> * That behaviour change is visible to existing routes, so a short note in the
> 4.24 upgrade guide is worthwhile.
> * It affects all three consumer types (commit, tag and branch). The producer
> is not affected.
> h3. Related
> * See also CAMEL-26652: failed exchanges are marked consumed and never
> delivered again. Its fix relies on the exception handler and on a delay that
> can be raised.
> * CAMEL-19665 (commits 51f270663f86 and 83ab5f1536c5) changed {{GitEndpoint}}
> from {{DefaultEndpoint}} to {{ScheduledPollEndpoint}} without adding the call.
> * Similar bugs, already fixed: CAMEL-22558 (the camel-jira consumer ignored
> the delay option) and CAMEL-24357 (the camel-aws2-s3-vectors consumer ignored
> the delay option).
