Can we trigger EventBus on the server and catch abp.event.on #11469

one year ago Question

We have been trying to use notifications but we're getting SQL timeouts because I gather we're abusing notifications so we'd like to use EventBus but it doesn't look like events triggered on the server can be observed client side, is that correct?

We essentially have a background job that is gathering information from a very slow API and we'd like to continue to notify the user when actions are still occurring, but not using IAppNotifier (as it causes the DB timeout issues).

We are thinking about using a SignalR hub that can handle IAsyncEventHandler<SuperCoolEvents> and then send a message to the user by user id which then does the abp.event.trigger with the same data.

If it does work, it'd be nice to see this in the system generally - though it sounds like this would only work if SignalR is enabled, not sure how you'd do it otherwise.

The type or namespace name 'ApplicationPartAttributeAttribute' does not exist #11437

The type or namespace name 'ApplicationPartAttributeAttribute' does not exist in the namespace 'Microsoft.AspNetCore.Mvc.ApplicationParts' (are you missing an assembly reference?) PatientManagement.Mobile.MAUI (net7.0-android)

Vulnerability Scan Results March 2022 #10978

2 years ago Question

What is your product version? v11.1
What is your product type (Angular or MVC)? MVC
What is product framework type (.net framework or .net core)? net6.0

We're in the very end of a process that has required us to get a Privacy Impact Assessment, Threat Risk Assessment, Penetration Test and Vulnerability Scans and there are some items that we can't resolve because they are internal to this project.

1. Page.js contains an insecure version of jquery:

"/saas/js/page.min.js contains jquery 3.4.1 which has known vulnerabilities."

The main site uses 3.6.0 (latest), can page.js use that already correct version?

2. User session timeout does not work propertly:

"The application does not terminate users’ sessions after session timeout; users’ sessions can be resumed without login to the (oauth provider) again."

This might just be configuration, but we're not certain where.

Login Issue w/ Antiforgery Tokens #10654

2 years ago Question

(Using product version 10.5.0 .NET Core MVC)

Getting an error on login following a specific sequence:

User is logged in and opens change password modal,
clicks link to Forgot Password page (is logged out),
clicks Back to exit, is directed to Login page,
and attempts to log in with the correct credentials

Instead of successfully logging in, a 400 bad request response is sent back. Upon closer inspection, an ASP.NET Core antiforgery token is lingering in the cookies and fails the automatic validation applied to the Login controller method.

Adding an IgnoreAntiforgeryToken attribute to the login method is the most obvious solution. Does this interfere with ABP's automatic CSRF validation or will the login form still be protected? Might something else be missing that would prevent this problem altogether?

Different threads concurrently using the same instance of DbContext #10627

2 years ago Question

What is your product version? v10.5.0
What is your product type (Angular or MVC)? MVC
What is product framework type (.net framework or .net core)? Net5.0

We've been experiencing some growing pains here and on watching a really informative webinar yesterday (https://blog.jetbrains.com/dotnet/2021/10/08/profiling-and-fixing-common-performance-bottlenecks-webinar-recording) we've tried to start working on some of those anti-patterns we were using (like awaits inside loops).

Now that we've started, however, we're getting the error:

A second operation was started on this context before a previous operation completed. This is usually caused by different threads concurrently using the same instance of DbContext

Here's one such example, the original code:

The modified code:

What are we missing here? We can wrap things in semaphoneslim to correct this (since lock can't have async code inside) but that doesn't "smell" right at all ..

New Project Immediate Xamarin Failure #10467

2 years ago Question

What is your product version? 10.3.0 or 10.4.0
What is your product type (Angular or MVC)? MVC
What is product framework type (.net framework or .net core)? .NET Core

If we generate a new demo project today with these settings:

ASP.NET CORE MVC & jQuery
NET 5
10.4.0 (or 10.3.0)

And attempt to run the Xamarin project in the simulator, following the dev guide, it fails with:

Error processing the method 'System.Void Abp.Auditing.AuditingInterceptor/<InternalInterceptAsynchronous>d__6`1::MoveNext()' in the assembly 'Abp.dll': Value cannot be null.

Looks like it's something related to the linker going wrong.

Simple console/benchmarkdotnet project sample #10376

3 years ago Question

We're trying to optimize some specific app service layer code, but we're having a hard time getting a console app setup with BenchmarkDotNet to get started. Has anyone setup someting similar that we can take a look at?

We have an app service that's doing quite a bit of manipulation and we're hoping to resolve that app service in the benchmark app so we can compare one method "Evaluate" of the app service to another, like "OptimizedEvaluate".

AbpValidationException being thrown when language != english #9874

3 years ago Question

Prerequisites

What is your product version? 10.0.0
What is your product type (Angular or MVC)? MVC Jquery
What is product framework type (.net framework or .net core)? Net 5

We've developed a system using aspnetzero, works great. We're now down to testing other features that we didn't pay much attention to, like localization. We have a case where a modal popup works fine when the language is English, and fails (model binding with the view model, my guess) when the language is anything but english.

I know it says there are model violations, but it doesn't necessarily make sense here.

DI and the Telerik Reporting Problem #9784

3 years ago Question

So, I know that Telerik Reporting has been asked about here before but I'm so close and I just need a nudge. For some unknown reason, Telerik doesn't have the ability to have a Net Core reporting project (something to do with System.Drawing) but you can create a .NET 4.8 project, add the reports and then view those reports from a Net Core 3.1 app. I have that all working. My problem now is DI.

The Core project is Net Core, the Application project is Net Core but the reporting project can only reference NetStandard.

I do have a module for the reporting project that the Mvc then depends on, the report is correctly being resolved using IocManager:

/// <summary>
/// See https://docs.telerik.com/reporting/knowledge-base/how-to-inject-custom-dependency-in-reports-controller-of-dot-net-core-application
/// </summary>
/// <param name="report"></param>
/// <param name="operationOrigin"></param>
/// <param name="currentParameterValues"></param>
/// <returns></returns>
public ReportSource Resolve(string report, OperationOrigin operationOrigin, IDictionary<string, object> currentParameterValues)
{
    var reportType = Type.GetType(report);

    if (reportType == null) throw new UserFriendlyException($"Could not find a corresponding report for type '{report}'.");

    var resolvedReport = (Report)_iocManager.IocContainer.Resolve(reportType);

    var reportSource = new InstanceReportSource { ReportDocument = resolvedReport };

    return reportSource;
}

But, now that I can view the report - how can I get data from the system?

So, what are the possibilities here?

AddRazorRuntimeCompilation doesn't not appear to be working #9348

4 years ago Question

With the last few updates, our team is finding that any change to razor causes the next load of the page to throw an exception. This is causing development to slow way down as we have to build every single time we make small changes.

It should be configured as it always has been and yes, debug constant is on in this context:

services.AddControllersWithViews(options =>
            {
                options.Filters.Add(new AbpAutoValidateAntiforgeryTokenAttribute());
            })
#if DEBUG
                .AddRazorRuntimeCompilation()
#endif
                .AddNewtonsoftJson();
