IOException when building from mapping pack files into memory

[ssa3512]

Several developers reporting and at least one CI build failed. Rolled back to 3.3.37 for now.

System.IO.IOException: Not enough memory resources are available to process this command.

@qmfrederik Could this be because of trying to map a single, very large pack file? Or is this due to a memory leak in the object cache you build up?

[qmfrederik]

Thanks, for reporting, @ssa3512 . Could you share the size of your pack files (i.e. .git\objects\pack\*.pack)?

Do you know whether MSBuild is running as a 32-bit or 64-bit process?

[ssa3512]

@qmfrederik here is from the CI server that failed. Working on getting from the users that also reported issues.

The CI build was set to MSBuild x86 - I am assuming this controls what it runs with. As for the users, they are using Visual Studio 2019 16.8 or newer. Is there a setting somewhere that would control 32 vs 64 bit for building?

[AArnott]

None of these files look very large, but I suppose perhaps the 129MB+ files might be hard to map into contiguous memory that large.
@qmfrederik I believe when memory mapping files that it's possible to map only portions of files at a time. I wonder if a fix for this would be to set a max "window" size to map into memory and move it as necessary?

[filipnavara]

Here's one more data point:

filipnavara@172-4-1-17 emclient % ls -l .git/objects/pack
total 8302608
-r--r--r--  1 filipnavara  staff    14635208 Jun 11 10:00 pack-80c7ee391de74c1da6faf79c8b49c68d8c2dacf6.idx

Mapping the index files is fine but mapping the whole pack files is definitely problematic.

[filipnavara]

Here's an experiment with mapping only small chunks of the pack file: https://github.com/dotnet/Nerdbank.GitVersioning/compare/master...filipnavara:big-pack?expand=1

The approach is not perfect but it highlights few things:

• There's unused code for GitPackPooledStream.
• It's likely going to have performance impact so it may be worth the trouble to choose different strategy for small pack files, big pack files and/or 32-bit/64-bit processes.
• Not sure what is the motivation for MemoryMappedStream compared to the built-in MemoryMappedViewStream. It could be performance or different behaviour when disposing. Either way it doesn't handle non-aligned offsets. The memory mappings have to be aligned to page size boundaries on the OS level APIs. .NET tries to hide this restriction by aligning the mapped block to nearest smaller offset and then making the window large enough. Then it makes the stream point to the actual offset within the first page of the view.
• Mapping small chunks may turn out to be less efficient in worst case. The mapping is always aligned to OS page size so if we create a view for each individual object then two small adjacent objects will end up with two bigger views. Moreover, to read the object size we have to first map a bit of the file to read the object header. I optimistically start with an 8Kb view, read the header and if the object is bigger, then remap to a bigger view. This is somewhat suboptimal.

In the end I have a feeling that it may be more reasonable to map only the index files and not the pack files. If it's a problem performance wise it's probably fine to do that only as a fallback when certain parameters are exceeded (file size threshold, 32-bit process, the mapping fails, etc.). .NET 6 will have better APIs to handle this kind of random reads (dotnet/runtime#53669) but unfortunately that's still some months away.

@qmfrederik Do you have time to investigate @filipnavara's data and proposal?

[filipnavara]

I'd be happy to do some more testing and try out other approaches or even run benchmarks. However, with the window for .NET 6 runtime changes slowly closing in I need to focus on completing some work there before moving on to other projects.

[qmfrederik]

All help is welcome, so I'd be more than happy if @filipnavara wants to invest some time in this 😄 .

Not sure what is the motivation for MemoryMappedStream compared to the built-in MemoryMappedViewStream

I think the main reason was .Dispose behavior. Pooling streams had a significant impact on performance. There was an attempt to use the built-in version (0c5a573) which was reverted (61e877a, #521 (comment)).

In the end I have a feeling that it may be more reasonable to map only the index files and not the pack files.

Yes, that may be the case. If I remember correctly, the stream pooling and usage of memory mapped files was introduced at about the same time.
There's probably a real benefit for index files, since we do a binary search there.

It is possible that the memory mapping doesn't have much of a perf impact on pack files, and the real gain comes from stream pooling.

There are a couple of perf tests which run as part of CI, so it should be fairly easy to tell whether changes regressed performance or not 😃

Keep in mind the workaround we have of setting the NBGV_GitEngine environment variable to LibGit2 so you don't have to stick with the 3.3 version, folks.

I'm now starting to run into this in local dev too in VS. I guess VS 2022 can't come fast enough :P

Searching for a way to configure the use of 64-bit msbuild from VS but that doesn't seem to be possible. Guessing that's a limitation of a 32-bit process not being able to spawn a 64-bit one, but this certainly isn't my area of expertise.
https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild?view=vs-2019

So rather than need to run msbuild from cmdline, is there a way to perhaps toggle off ngvb in local dev? Which would probably be something we'd want in any case to avoid the compile-time overhead...

Is toggling it out of the csproj if not Release configuration a viable alternative? Can't say I've ever toggled off a package ref by Configuration. Feels a bit wrong; but trying to avoid getting the whole team to set an env var.

<PackageReference Include="Nerdbank.GitVersioning" Condition=" '$(Configuration)' == 'Release' ">
  <Version>3.4.190</Version>
  <PrivateAssets>all</PrivateAssets>
</PackageReference>

@benmccallum If you have the time to dig into this, could you give #626 a try and let us know if this fixes the problem for you? There may be a perf regression n macOS, but since you mention VS, I guess you're on Windows so you should be good.

Alternatively, set the NBGV_GitEngine environment variable to LibGit2 to sidestep the managed implementation altogether.

There's never a problem with 32-bit processes spawning 64-bit ones. It's just that that's not what msbuild in VS was designed to do.

[benmccallum]

@qmfrederik, I can look to give #626 a go at some point, is it available as a nuget preview release somewhere?

[AArnott]

@benmccallum It used to be, but it got GC'd by Azure Pipelines. I've queued a new build here: https://dev.azure.com/andrewarnott/OSS/_build/results?buildId=4966&view=results
You should be able to download the nupkg from the pipeline artifacts when it's done.

[AArnott]

This is now available in https://github.com/dotnet/Nerdbank.GitVersioning/releases/tag/v3.4.228

[benmccallum]

Thanks @AArnott , sorry I didn't get around to give feedback in time. Will get on the new version tomorrow and give it a whirl.

[benmccallum]

Seems to be working well for us on all platforms, 👍🏻 Thanks again
