@adriansev : I pushed today: 769182ca3b9a5e8968251326ec7bfe2417c3e98b 7c5e272cab6ae3e23e2988fc48f6eb038966a840 eb0e7bea766cf4941f4439e31832a0cc3949a92d this should allow you to use the checksum present in a metalink while extracting a file from ZIP archive. From comandline (assuming `file.meta4` points to a ZIP archive containing `file.txt` and a `md5` checksum for the file): - `xrdcp --cksum md5 -f --zip=file.txt --zip-mtln-cksum file.meta4 .` or with an envar - `XRD_ZIPMTLNCKSUM=1 xrdcp --cksum md5 -f --zip=file.txt file.meta4 .` You can also enable the functionality from Python by setting `ZipMtlnCksum` in the environment, e.g.: `EnvPutInt( 'ZipMtlnCksum', 1 )` for more details see: https://github.com/xrootd/xrootd/blob/master/bindings/python/libs/client/env.py#L41 Could you give it a try? -- You are receiving this because you are subscribed to this thread.
