Of note, I've disabled IPC on visual test runners as we generally don't
use IPC in these cases. Having it set means that the game will not open
while visual tests are open, which has been a complaint from devs in the
past.
Closes https://github.com/ppy/osu/issues/26510.
Time for a rant.
Technically, this "broke" with 9e8d07d314,
but it is actually an end result of upstream behaviours that I am
failing to find a better description for than "utterly broken".
Squirrel (the installer we use) has unit tests. Which is great, power
to them. However, the method in which that testing is implemented leads
to epic levels of WTF breakage.
To determine whether Squirrel is being tested right now, it is checking
all currently loaded assemblies, and determining that if any loaded
assembly contains the magic string of "NUNIT" - among others - it must
be being tested right now:
2442721748/src/Squirrel/SimpleSplat/PlatformModeDetector.cs (L17-L32)
If one assumes that there is no conceivable way that an NUnit assembly
*may* be loaded *without* it being a test context, this *may* seem sane.
Foreshadowing.
(Now, to avoid being hypocritical, we also do this, *but* we do this
by checking if the *entry* assembly is an NUnit:
92db55a527/osu.Framework/Development/DebugUtils.cs (L16-L34)
which seems *much* saner, no?)
Now, why did this break with 9e8d07d314
*specifically*, you might wonder?
Well the reason is this line:
3d3f58c252/osu.Desktop/NVAPI.cs (L183)
Yes you are reading this correctly, it's not NVAPI anything itself that
breaks this, it is *a log statement*. To be precise, what the log
statement *does* to provoke this, is calling into framework. That causes
the framework assembly to load, *which* transitively loads the
`nunit.framework` assembly.
(If you ever find yourself wanting to find out this sort of cursed
knowledge - I hope you never need to - you can run something along
the lines of
dotnet-trace collect --providers Microsoft-Windows-DotNETRuntime:4 -- .\osu!.exe
then open the resulting trace in PerfView, and then search the
`Microsoft-Windows-DotNETRuntime/AssemblyLoader/Start` log for
the cursed assembly. In this case, the relevant entry said something
along the lines of
HasStack="True"
ThreadID="23,924"
ProcessorNumber="0"
ClrInstanceID="6"
AssemblyName="nunit.framework, Version=3.13.3.0, Culture=neutral, PublicKeyToken=2638cd05610744eb"
AssemblyPath=""
RequestingAssembly="osu.Framework, Version=2024.113.0.0, Culture=neutral, PublicKeyToken=null"
AssemblyLoadContext="Default"
RequestingAssemblyLoadContext="Default"
ActivityID="/#21032/1/26/"
Either that or just comment the log line for kicks. But the above
is *much* faster.)
Now, what *happens* if Squirrel "detects" that it is being "tested"?
Well, it will refuse to close after executing the "hooks" defined via
`SquirrelAwareApp`:
2442721748/src/Squirrel/SquirrelAwareApp.cs (L85-L88)
and it will also refuse to create version shortcuts:
2442721748/src/Squirrel/UpdateManager.Shortcuts.cs (L63-L65)
Sounds familiar, don't it?
There are days on which I tire of computers. Today is one of them.
A lot of sentry error reports are coming from realm / EF failures due to the host operating system being too old. Let's give the user some proper feedback rather than a silent crash and error report hitting our logging.
Closes https://github.com/ppy/osu/issues/17965.
Note that this will cause a second osu! icon to appear after running the
application (after any update). As per the inline comment, this will
eventually be resolved via https://github.com/clowd/Clowd.Squirrel/issues/24.
I do think having context menus working is more important than duplicate
icons.
Note that for anyone who already has a pinned taskbar icon, it will need
to be manually unpinned and repinned after a future update to actually
fix this issue.
Thanks to @caesay for help with investigation.
Using `Environment.CurrentDirectory` for storing / reading files is dangerous as the current directory is mutable and can be changed when performing a certain operation (like opening solutions in roslyn type reference builder for example).
