[R-pkg-devel] Checksums changed on CRAN without any visible modifications to files.
Dear Uwe, sorry to bother you again with it, but I was wondering if you had some more idea about what happened. I just received another one, this time about mgcv_1.8-23.tar.gz. It goes beyond my understanding as to why the MD5 sums would change without any change to the package. Is there anything I can check at this side to make it easier for you? Cheers Joris

Dear Uwe, Thank you for willing to take a look. In the report it was about the following tarballs : pkgmaker_0.22.tar.gz rngtools_1.2.4.tar.gz RcppProgress_0.4.tar.gz Our sysadmin tried diff -ru, but couldn't find any difference in the text files.

When CRAN repacks and changes the DESCRIPTION file, the checksums
change, of course.
Best,

Dear Uwe,
I understood that from the previous issue. In this case however, none of
the files -including the DESCRIPTION file- were changed. Am I right in
suspecting that a package is repacked when moved to the archive?
No, we do not repack generally then. Perhaps the package got orphaned? Which package / tarball were you talking about? I can take a look why that one was changed and inspect why the checksum changed. Best, Uwe Ligges I
suspect that the tool used to repack the package is using gzip, and it is possible to repack without adding a timestamp as explained here : https://serverfault.com/questions/110208/different-md5sums-f or-same-tar-contents I can explain the different checksums when some things are changed to our HPC sysadmins, but they have -understandibly- difficulties with checksums changing for released source tarballs. Is it possible to adapt the archiving so that at least for identical tarballs the md5 sums remain the same? Or if you have other suggestions to deal with this without having to change hardcoded checksums in the easybuild repos, that would be very welcome too.
