error | Error: ENAMETOOLONG: name too long, open [DUE TO:] [WINDOWS limitation of 255 chars / path segment length] [Linux limitation of 255 chars / path length]

Hello,

I have tried to generate the csharp code from a swagger that has a pretty deep level of nesting and got this error:

autorest readme.md --csharp

>> error I got:
error   |   Error: ENAMETOOLONG: name too long, open 'C:/swagger/generated/Models/ComponentsPidniwSchemasNfadevicePropertiesSpecPropertiesDeviceEos4271FPropertiesNetworkinstanceItemsPropertiesProtocolItemsPropertiesBgpPropertiesRibPropertiesAfisafiItemsPropertiesIpv4UnicastPropertiesLocribPropertiesRouteItemsPropertiesUnknownattributeItems.cs'

This issue looks like a regression of https://github.com/Azure/autorest/issues/3474

I have tried with the latest version of autorest. The version from https://github.com/Azure/autorest/issues/3474 just blocks, probably it is not supported anymore by the dotnet version I have installed.

Thank you.

Nonetheless, seems that the path segment is still limited to 255 characters.

It would be nice if Windows documents contained this kind of information.

I suppose we can close this issue with a non-solvable tag, because of a Windows limitation, in this case. FWIW, the autorest model generation on Windows ended up producing much more results, as the path segment is limited to 255 chars versus the Linux limitation for full path at 255 chars.

Thank you, Adrian Vladu

If you notice the 1st one the filename is 256 char long and the 2nd is 255 which as far as I can tell is still the limit for path segments regardless of the total path limit.

If you just try to create the file in windows it will fail as well.

There isn’t anything autorest can do here unless this isn’t the case. That filename anyway must be due to a very nested set of anonymous definitions which have no names and would result in a terrible SDK.
