            How to download files that were marked as dependencies from Artifactory
            Asked 2021-May-26 at 08:15

            Answered 2021-May-25 at 15:44

            I am not sure how the dependencies of projectA are associated to projectB (if it just through a build info or specific section or also additional properties were added), but if you are looking for more flexibility on which artifacts you want to download you can try to use AQL

            You can specify which artifacts you want to download and from which build id and number and if this dependency is used in a specific module or not. If these dependencies has common properties you can try to download based on these criteria as well.

            AQL can also be combined with file specs of course.

            Further looking into "Avoid context.sync in loops"
            Asked 2020-Jun-10 at 03:24

            Article Avoid using the context.sync method in loops renders incredible help on the Word add-in I am developing. I see huge performance improvement after adopting the technique introduced in this article.

            This really made my day. Now there is only one sync-loop left that I am not sure how to deal with it. Here is the sample code. The culprit function with context.sync() runs inside a loop, forming the sync-loop that drives me nuts. Any idea how to optimize it? For some reason, the two functions cannot be merged.

            Currently, your code does something like is shown in this demo:https://jsfiddle.net/BlackLabel/kL5xahve/ - which is wrong because the options are defined after the chart has been initialized.

            The easiest solution is to destroy the chart and initializing it once again after the change language.

            DDD, Domain Services and Events
            Asked 2019-Apr-01 at 22:51

            Situation:

            To work with domain events, Jimmy Bogart proposed a method for storing events in aggregates.

            This, from my point of view, is a very convenient approach. However, what about the case of a domain event in the domain service?

            Domain Service should not have a state (stateless). In this case, in theory, the IDispatcher event dispatcher must be injected into the constructor of such a service.

            Question:

            To avoid introducing into the domain service of the event dispatcher, the suggested alternative approaches are correct:

            1. Saving in the domain service of events of the last operation. However, this will violate the principle of stateless for the domain service.
            2. Return the list of events from the service method based on the results of the operation (in the return method or in another way, depending on the capabilities of the programming language).
            ...

            Note: that post was written about five years ago. You may want to review his more recent (and more detailed): Life Beyond Distributed Transactions: An Apostate's Implementation

            Domain Service should not have a state

            Right - and for this reason, it is very suspicious that you would want to assign responsibility for domain events in the domain service.

            You might use a domain service to calculate events for the aggregate, but the storage would still belong to the aggregate structure itself. So that would probably look like a function (or, if you prefer, a method on the domain service) that accepts some arguments provided by the aggregate and returns events.

            Including user id in domain events
            Asked 2019-Mar-11 at 12:26

            I've been working on a new document management project that uses DDD architecture. I'm new to DDD and event driven design, so it's been a learning experience.
            My application is structured like this:

            • MyProgram.Domain
            • MyProgram.Infrastructure
            • MyProgram.App
            • MyProgram.WebApi

            Domain has all of my domain logic, infrastructure is persistence, application is mostly commands and handlers, and the webapi is just the thing webapi.

            Right now I'm working on implementing user authorization, and at the moment I've decided on using authorization handlers that will do permissions check before a command or query is executed. I think this gives me good flexibility perform complex resource-based authorization, since many of my permissions will depend on the current state of a certain entity.

            So that is working out so far, I've implemented authorization in my application layer, leaving most of the user-specifics out of my domain model.

            Now, the problem I'm trying to figure out is how to best include user information in my domain events, raised from my domain classes.

            Example, I have a certain aggregate, let's say its document, and the document has a certain approval workflow. So when the document gets approved, I want to raise a domain event such as

            That sounds like the authorization is an important part of the business rules and should be implemented in the domain layer. The fact that you have the need to enrich the domain events with user information is an indicator that the user should be part of the domain.

            Without knowing the domain exactly I could imagine you have an invariant, something like: "A document can only be approved by the line manager of the author". You can not assert this invariant in the domain without the concept of users/roles.

            I've implemented domain dispatching using a similar pattern here by overriding the SaveChanges method on my DbContext. I have entities with domain events that inherit a base abstract class that contains a list of domain events. I now want to enforce that the abstract class to have an Id property of a generic type.
