QUARTZ.NET CHANGELOG

http://www.quartz-scheduler.net

Release 3.2.3, Oct 31 2020

This release addresses issue with Autofac integration and adds new integration package Quartz.OpenTracing to allow integration with OpenTracing.

  • NEW FEATURE

    • Add Quartz.OpenTracing support (#1006)

  • FIXES

    • Xamarin Android can't get scheduler (#1008)
    • Autofac job factory registration fails (#1011)

Release 3.2.2, Oct 19 2020

This release addresses regression in scoped job resolution which was introduced by job factory refactoring done in 3.2.1.

  • FIXES

    • Fix scoped job resolution (#998)

Release 3.2.1, Oct 18 2020

This is a maintenance release containing mostly bug fixes.

MS dependency injection job factory configuration was unified and you can now configure relevant options like whether to create a separate scope with using just the UseMicrosoftDependencyInjectionJobFactory and its callback. Now scoped jobs also get their properties set from job data map.

Pre-configuring Quartz options from appsettings.json with services.Configure(Configuration.GetSection("Quartz")); now also works as expected.

  • FIXES

    • Make QuartzOptions Triggers and JobDetails public (#981)
    • Fix configuration system injection for dictionary/quartz.jobStore.misfireThreshold in DI (#983)
    • XMLSchedulingDataProcessor can cause IOException due to file locking (#993)

  • IMPROVEMENTS

    • Unify MS dependency injection job factory logic and configuration (#995)
    • Improve job dispatch performance to reduce latency before hitting Execute (RAMJobStore) (#996)

Release 3.2.0, Oct 1 2020

This is a release that focuses on restructuring some packages that warrants for a minor version number increment.

Now Quartz no longer has hard dependency on Microsoft.Data.SqlClient, you need to add that dependency to your project if you are using Microsoft SQL Server as backing store for your project. Now requirement is in line with other providers/drivers.

There's also important fix for SQL Server where varying text parameter sizes caused query plan pollution.

  • BREAKING CHANGES

    • Remove dependency on Microsoft.Data.SqlClient (#912)
    • LogContext moved from Quartz namespace to Quartz.Logging namespace (#915)
    • For Full Framework, System.Data.SqlClient is again the default provider, Microsoft.Data can be used via provider MicrosoftDataSqlClient (#916)

  • FIXES

    • Revert change in 3.1: CronExpression/cron trigger throwing NotImplementedException when calculating final fire time (#905)
    • Use 2.1 as the minimum version for the .NET Platform Extensions (#923)
    • ServiceCollection.AddQuartz() should register default ITypeLoadHelper if none supplied (#924)
    • SqlServer AdoJobStore SqlParameter without text size generates pressure on server (#939)
    • DbProvider initialization logic should also read quartz.config (#951)
    • LoggingJobHistoryPlugin and LoggingTriggerHistoryPlugin names are null with IoC configuration (#926)
    • Improve options pattern to allow better custom configuration story (#955)

  • NEW FEATURE

    • Introduce separate Quartz.Extensions.Hosting (#911)
    • You can now schedule job and trigger in MS DI integration with single .ScheduleJob call (#943)
    • Support adding calendars to MS DI via AddCalendar (#945)

Release 3.1.0, Jul 24 2020

This release concentrates on performance and bringing support to de facto Microsoft libraries like dependency injection and ASP.NET Core hosting. A big change is that now SQL queries use parametrized scheduler name, which allows database server to reuse query plans and use indexes more optimally. This will help especially clusters which have large number of nodes. The SQL server indexes were also revisited and their amount reduced by using smarter covering indexes.

There is also a very important bug fix present for lock handling on retries. There was a possibility for a deadlock in database lock handling in some situations.

  • BREAKING CHANGES

    • minimum supported .NET Full Framework is now 4.6.1
    • changed SQL commands format in Quartz.Impl.AdoJobStore.JobStoreSupport (see also #818). Affected are only schedulers that use customized configurations of SQL commands in Quartz.Impl.AdoJobStore.JobStoreSupport, e.g. SelectWithLockSQL. Migration example:
<!-- Quartz <=3.0.7 -->
<item key="quartz.jobStore.selectWithLockSQL">SELECT * FROM {0}LOCKS WITH (UPDLOCK,ROWLOCK) WHERE SCHED_NAME = {1} AND LOCK_NAME = @lockName</item>
<!-- Quartz >=3.1.0 -->
<item key="quartz.jobStore.selectWithLockSQL">SELECT * FROM {0}LOCKS WITH (UPDLOCK,ROWLOCK) WHERE SCHED_NAME = @schedulerName AND LOCK_NAME = @lockName</item>

  • FIXES

    • DailyTimeIntervalTriggerPersistenceDelegate does not store weekdays in correct format

    • XMLSchedulingDataProcessorPlugin uses new XML format that allows more control over triggers but no support for calendars
    • There are extension methods for the new trigger builder that allow you to set trigger specifics
    • Client Profile is now supported and there are separate DLLs for client profile
