I have found a weird "bug" in @xunit that I'm having trouble tracking down.

In 2.7.0 we shifted a SynchronizationContext that was always used to one that's now used conditionally (to support async void unit tests). Two users have come forward saying their tests are now hanging. I've identified deadlocks in one's code, but how strange is it that the removal of a feature surfaces a bug in someone else's code?

They end up with a different way for their continuations to get scheduled. It shouldn't in theory be any different, since everything should end up in the .NET ThreadPool but still, it seems to help. I'll be honest that I'm confused why. Is it our use of TaskCreationOptions.LongRunning that's breaking their logjam?

It's a harsh reality when you realize you're not going to live long enough to see the utopia promised by sci-fi.

It's worse when you're worried that nobody will.

I’m currently reading The Stand by Stephen King and just came upon a name that is making me consider re-reading the Dark Tower series.

@kpwags Dark Tower is so good. I just wish I hadn't read the afterward he warned us not to read.

Also, book 4 guts me every time. We know bad things are going to happen and he makes us fall in love with her anyways, the cruel and brilliant bastard.

Let me preface this next statement by calling out that I am literally the author of the first, production worthy IoC container in the .NET space, but...

.NET systems should strive to use the IoC container much less than they commonly do now, and make that usage dirt simple. A little bit of functional decomposition is all it takes sometimes.

And stop depending on mock object libraries as a one size fits all crowbar for testability

bradwilson,
@bradwilson@mastodon.social avatar

@jeremydmiller An interesting side effect of this kind of testing comes when you're writing a library rather than an application. Do the testing hooks you've introduced into the production code get exposed to end users? Do you have a strategy to prevent end users from using them? Do you even need one?

My curmudgeon filter kicks in when someone describes a song as "a bop" and assumes it's not for me. I might be in for "a jam", but mostly I'm looking for "a skull crusher".

@KirillOsenkov @JasonPunyon Except it's demonstrably wrong as illustrated. The second set of insertions are obviously 1/4 and 3/4, but labeled as 1/3 and 2/3. Count the segments.

bradwilson,
@bradwilson@mastodon.social avatar

@JasonPunyon @KirillOsenkov There are at least two things you could do:

  1. Measure it. That's why I said count the segments. There are five locations and four segments. Number all the locations from the left from 0 to 4. Your 1/3 mark is at the 1 spot, which means it's 1/4 (there are four segments, not 3).

  2. Reason about it. You're placing a dot half way between 0 and 1/2. (0+0.5)/2 is 0.25 (aka 1/4). Same for the other side: (0.5+1)/2 is 0.75 (aka 3/4).

bradwilson,
@bradwilson@mastodon.social avatar

@JasonPunyon @KirillOsenkov This of course is all based on the unstated (but seemingly illustrated) assumption that you're creating equal length segments every time you insert. 1/3 is between 0 and 1/2, but not where you've illustrated it to be.

    I feel like I want to explore enough of Roslyn Source Generators so that we could remove 100% of the reflection code in @xunit.

    It could in theory have a massive impact on extensibility, and may require hooks so that 3rd parties can participate in the compile-time generation of the metadata model that would be needed to replace reflection.

    I also suspect this would nuke our ability to do source based discovery, though I'm not aware whether anybody is currently using it.

    bradwilson,
    @bradwilson@mastodon.social avatar

    The team that built source based discovery into Visual Studio did it without using our APIs, despite the fact that they've been there since 1.0. When you see Visual Studio doing a bad job of source based discovery for @xunit tests, that's why: they implemented their own 80% version and then abandoned the work there. In my opinion they were basically trying to solve a problem for an internal team and everything else was secondary.

    bradwilson,
    @bradwilson@mastodon.social avatar

    At this point I have zero reason to suspect that they'll ever open that model up and let us own that discovery code though we've been requesting it for as long as it has been a feature (a decade now? I can barely remember when the discussions first started). So killing our support for source based discovery might not be that big a deal at this point.

    Lossless audio sounds better than the MP3s I made in 2000, when I encoded them at the lowest viable resolution to get as many as possible on my Creative Nomad Jukebox. It does not sound notably better than the high-resolution encoded MP3s I make today. That said, when making music or uploading it to streaming, I do it with lossless files because in those situations, more information is better.

    @scalzi I rip everything to FLAC as a "perfect" archive, but then use an automated script to convert them to 256k MP3 for smaller size (for putting my music collection on my phone, for example). I stream the FLACs around the house at home.

    I have replaced "cat" with "bat" in PowerShell, and written a "cat" function that makes it more useful to me. Bat is a replacement for cat that syntax highlights the output.

    I'm able to support:

    $ cat *.cs
    $ dir -r -fi *.cs | cat

    I have not yet been able to support piping, so that has to stay with invoking bat:

    $ curl -ks https://sh.rustup.rs | bat

    (I'm not 100% sure if I can support both piping from raw text as well as piping filenames.)
