@ScottDemarest : we have removed the `append` flag in XRootD5 from the client because we actually never supported this functionality properly. From what I see it was also never really supported in the bindings, the `currentOffset`: https://github.com/xrootd/xrootd/blob/dfa0586ae4ac75b6a61345783eb95b7b1e6a1b38/bindings/python/src/PyXRootDFile.hh#L67 is being used only for the `readline` functionality. Why do you need the open flag? Is that you used to have it and now you are getting a build error (in this case I would ask you just to remove the flag), or do you need this functionality implemented? -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1731#issuecomment-1174927800 You are receiving this because you are subscribed to this thread.
