net7 - Build freezes when publishing trimmed app with net6+ class libraries #87220

michaldobrodenka · 2022-12-15T12:22:35Z

I have a sln which contains several class libraries and one executable cmdline csproj. I'm modernizing whole solution, removing mono/net461 executable, upgrading class libraries from netstandard20 to net7.
When publishing my app with parameters:

dotnet publish my.csproj -r linux-arm -p:PublishTrimmed=True -p:TrimMode=partial --self-contained true -c Release -f net7.0

and one specific csproj of my class libraries is set to net7.0 build freezes. on line
C:\Program Files\dotnet\dotnet.exe exec "C:\Program Files\dotnet\sdk\7.0.101\Roslyn\bincore\csc.dll" ...
Freezing means than NET host process takes almost all cpu, a several Gigs of RAM.

To "unfreeze" build I have to:

remove trimming ( -p:PublishTrimmed=True -p:TrimMode=partial ) - without trimming build is completed in 20sec
set this one library to netstandard20 and build with net7 SDK
set all csproj files in solution to net6 and build in net6 SDK - net6 build completes in about a minute without problems

Building it on Windows 10,11 and in linux docker.

What I've tried and didn't help:

build with MS net7 SDK docker
build for different runtimes - linux-x64, win-x64, linux-arm...
SDK 7.0.100 and 7.0.101

Unfortunately project is closed source. But I can run some test, access my desktop remotely or something like that.

@dotnet/linker-contrib a new issue has been filed in the ILLink area, please triage

matheusavi · 2023-01-03T19:02:40Z

Same issue building on al2! I needed to set an 8gb machine to build a small project using AOT.

michaldobrodenka · 2023-01-04T08:48:27Z

I couldn't finish build even after several hours.

biste5 · 2023-01-04T11:46:41Z

for us, our Blazor WASM project builds in about 4 minutes with .NET 6 or without trimming, 1+ hour with .NET 7 and trimming

michaldobrodenka · 2023-01-04T11:48:39Z

Maybe I could try to wait more than 6 hours. In net6 it is build within 100seconds.

michaldobrodenka · 2023-02-17T22:24:23Z

Waiting 10hours didn't help.
I've attached to running csc.

The same issue with sdk 7.0.200. Last version I was able to build my project with was something like net7 Preview7

michaldobrodenka · 2023-02-17T22:27:46Z

michaldobrodenka · 2023-02-24T21:52:28Z

still hangs up in net8 preview1

michaldobrodenka · 2023-02-25T08:59:30Z

I have a strong suspicion it's somehow connected to using netstanrard2.1 libraries in solution

michaldobrodenka · 2023-03-23T09:56:26Z

I have a strong suspicion it's somehow connected to using netstanrard2.1 libraries in solution

it's not about netstandard2.1. It was just that net8 Preview 1 could not trim netstd2.1 libs.

Still reproducible in latest 7.0.4 & 8P2

michaldobrodenka · 2023-04-25T20:40:33Z

Ok, I found a little workaround - when all referenced csprojs are net5 or lower, main project (net6.0, net7.0) builds normally with net7 SDK. So I can use features later than netstandard2.1, just not latest one - 6/7.

sbomer · 2023-06-07T16:53:02Z

@michaldobrodenka this is likely the same issue as #86379. Are you able to try building your project with the latest nightly 8.0 SDK available at https://github.com/dotnet/installer/? We are also planning to backport the fix into an upcoming 7.0 servicing release.

@sbomer I've tried to build it with latest nighly, but seems that I can't get versions or something right:

Maybe I'll wait for next official net8 Preview/net7 and retest it.

Ok, after clearing nuget local cache, I'm able to start build, still freezes, but there is a problem with ILLink task version

warning NU1603: TapHome.Core.Translations depends on Microsoft.NET.ILLink.Tasks (>= 7.0.100-1.23211.1) but Microsoft.NET.ILLink.Tasks 7.0.100-1.23211.1 was no t found. An approximate best match of Microsoft.NET.ILLink.Tasks 8.0.0-preview.2.23128.3 was resolved.

Maybe I should add ILLink task nuget?

sbomer · 2023-06-08T17:17:20Z

@michaldobrodenka thanks for giving it a try. For the nightly SDKs you'll need to add nuget feeds mentioned under https://github.com/dotnet/installer#installers-and-binaries. For projects using the illink analyzer targeting net7.0 you will need the dotnet7 feed specifically.

michaldobrodenka · 2023-06-09T15:49:37Z

I tried targeting net8 & latest net8 nightly (Preview6), build is still freezing. I'll retest it within a few weeks

sbomer · 2023-06-09T16:54:05Z

@michaldobrodenka sorry, I forgot to mention that your project needs to target net8.0 to get the analyzer fix, at least until we make the servicing fix (dotnet/linker#3217). And note that you should be able to work around this by setting <EnableTrimAnalyzer>false</EnableTrimAnalyzer>. Then you won't see trim compatibility warnings at build time, but you can instead rely on the warnings produced when publishing.

michaldobrodenka · 2023-07-12T08:47:22Z

7.0.9 - still freezes
<EnableTrimAnalyzer>false</EnableTrimAnalyzer> - to one of the libraries and it builds ok!

sbomer · 2023-07-13T16:02:33Z

Thanks for checking! Looks like the servicing fix should ship with 7.0.10.

agocke · 2023-08-09T16:18:04Z

This should be fixed. Newly discovered problems are likely new issues.

michaldobrodenka · 2023-08-10T12:08:48Z

This should be fixed. Newly discovered problems are likely new issues.

Is the fix merged in 7.0.10? Because I tried it and build still hangs without <EnableTrimAnalyzer>false</EnableTrimAnalyzer> in one of the libraries

@michaldobrodenka thank you for following up. I confirmed that the fix shipped in the 7.0.10 servicing release (7.0.400 SDK), so this sounds like a different bug. Is there any way you could provide us with a repro, perhaps a simplified bit of code from the library that exhibits the hang?
