DataCache | Simple disk and memory cache for iOS | Caching library

I'm trying to create a Distributed SQL Server Cache table for a .NET Core project using this command:

dotnet sql-cache create "Server=localhost;Database=CacheDb;User Id=SA;Password=Some123\!@#;" dbo DataCache

The password is Some123!@#, so I'm trying to escape the special characters using \ but it doesn't see to work as I'm getting: An error occurred. Login failed for user 'SA'.

I have an image of microsoft/mssql-server-linux running in a docker container. The version is Microsoft SQL Server 2017 (RTM-CU13) (KB4466404) - 14.0.3048.4 (X64).

I'm able to run my web applications using that connection string (without needing to escape special characters), but I'm unable to make that connection string work using Terminal command.

Any help is appreciated. Thank you!

I've created a service worker that performs a fetch and then immediately stores the data in the cache.

I would like to create an array, then append to the array with the data output of a spawned child_process, then use that array in an child_process.stdout.on('end',...) callback.

Originally I was trying this:

I am making a Javascript page that requests data on user events

A lot of data needs to be retrieved per event, so I get a small amount of the data with a single AJAX request so I can show updates. The callback recursively requests more data via AJAX until there's no data left to get. Within this "chain", everything goes well.

Problems, however, arise when an user fires more events when a different chain is already running. Both chains use the same data object, so data gets lost. What is the proper way to queue these user events so they don't run concurrently? I've added a mutex (https://github.com/kirill-konshin/mutex-promise) but that doesn't take into account the AJAX request.

General code structure:

My build system, which uses meson, puts some files my application needs on AppDir under AppDir/usr/share/myapp/resources. The application needs both, read and write to those files when it is running. The files are in AppDir when I look at it, but when the .AppImage is generated, the standalone running executable cannot access those files. When integrating the application with the desktop, the application gets installed in ~/Applications, but it doesn't contain those files.

Here is a visualization of how it looks when the application is installed on the system without using AppImage (ninja install)

My application uses a Glade file and also cached data in a JSON file. When I do the following, everything works okay as long as the user installs the application with ninja install

I have a data cache class (that uses the MemoryCache class).

The basic function of this class is to cache reference data. To get this reference data it needs an instance of an Entity Framework dbContext. This gets passed in by dependency injection (Simple Injector).

But this dbContext has a lifecycle of "per call" (AsyncScopedLifestyle). So to satisify this I put the call to setup the cache in a "scope" that expires after the call.

The cache gets invalidated every 2 hours and is re-queried. Unsurprisingly, the dbContext has been cleaned up by then (because it went out of the scope).

I can think of ways to get around this issue. But I want to know if there is a pattern I should be following for this kind of issue. (Most of my solutions have me passing the container into my cache class. But that seems to be a violation of several DI patterns.)

Anyone know of a design pattern to use when you have a reoccurring need for an injection inside of a class?

A bit more background:

• My cache class (called DataCache) gets the context from constructor injection.
• The call to set it up is made from the Configure method in Startup.cs. This looks like this:

taking my first steps in BitBake using this guide, setup works fine until the point when i run bitbake world, where i get this -

I have an UIImageView extension with a method to download an set image, the extension also contains an UIActivityIndicatorView which i set as a view before the image is loaded once the image is loaded i remove or hide the UIActivityIndicatorView from the UIImageView
