I'm getting a build error saying:

/Users/jz/Desktop/development/repositories/Xamarin-ResxEditor/packages/MonoDevelop.Addins.0.4.1/build/MonoDevelop.Addins.targets(125,5): error : Could not write folder info file: System.IO.IOException: Too many open files [/Users/jz/Desktop/development/repositories/Xamarin-ResxEditor/src/ResxEditor/ResxEditor.csproj]

Im running on OSX and the project is this. You could also have some information in the CI server with the same problem.

Can you give me some hint on this?

Try ulimit -u 2048 to bump the open file limit before invoking MSBuild. By default it's only 256.

Still getting the same error. @mhutch.

This is an issue in Mono.Addins, see mono/mono-addins#110 for another workaround

You can also modify the file handle limit on a more permanent basis, see https://gist.github.com/tombigel/d503800a282fcadbee14b537735d202c

No, but there is a workaround linked above

I didn't tested the permanent way but the ulimit -u 2048 didn't work for me. At the moment I have this in stand by.

@jzeferino @mhutch ulimit -u 2048 works for me but the building process so slow for me. If I'm building my solution with VisualStudio for Mac it takes 10-30 seconds but if I'm building my solution with vstool then it takes 3-4 minutes. I don't understand what is happening because all projects in solution are empty (there is not any code in them). Also I have a lot of errors in log:

@slluis is there any way we can suppress all the "invalid assembly" errors?

@mhutch Any updates?

KirillOsenkov added a commit to KirillOsenkov/MonoDevelop.AddinMaker that referenced this issue Nov 3, 2018
The unwritten contract of AddinFileSystemExtension.GetReflectorForFile expects it to cache the Reflector, and the base implementation does that:
https://github.com/mono/mono-addins/blob/e84472dcd17b61a904538e1cc2e19f4b064c7068/Mono.Addins/Mono.Addins.Database/AddinFileSystemExtension.cs#L170

AddinScanner.Dispose() then calls database.FileSystem.CleanupReflector ();:
https://github.com/mono/mono-addins/blob/e84472dcd17b61a904538e1cc2e19f4b064c7068/Mono.Addins/Mono.Addins.Database/AddinScanner.cs#L58

This change does two things:
1. Dispose of the Registry after the ResolveMonoDevelopAddins task is done, which in turn disposes the Cecil Reflector
2. Removes the overridden GetReflectorForFile from CecilReflectorExtension since that is equivalent to the base implementation but without the caching. The base implementation does proper caching.

The fix has many benefits, such as:
1. Not allocating many file handles
2. Cleanup file handles after use
3. Improve build perf from 3.4 to 2.1 seconds on a solution with two addin projects
