I don't know what 'gs-elpa' & 'Melpa' are, but maybe talking to upstream would be good here, and improving that behavior. If the file contents or non-timestamp metadata change, absolutely the timestamps should change. But otherwise, the timestamp should NOT change. -- Robin Hugh Johnson Gentoo Linux: Dev, Infra Lead, Foundation Treasurer E-Mail : robb...@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85 GnuPG FP : 7D0B3CEB E9B85B1F 825BCECF EE05E6F6 A48F6136 signature.asc Description: PGP signature

Thanks in advance Markus The only usable hook that we currently have for this is FETCHCOMMAND and RESUMCOMMAND in make.conf. You can replace them with a script that does the normal thing and then sets the timestamp. The default values are found in /usr/share/portage/config/make.globals. -- Thanks, Zac OpenPGP_signature Description: OpenPGP digital signature
[gentoo-portage-dev] Normaliser function for distfiles
Hello all, is it possible to do the following: after fetching a distfile portage runs an external normaliser program specified in an ebuild before checking the hash? My use case is the following: I would like to improve the gs-elpa program and provide a precomputed overlay for melpa. However the melpa distfiles are rebuilt everyday and cause checksum failures. However the only thing changing are the timestamps. Hence if a normaliser program could simply set all timestamps to some predefined value (say 1.1.1970) then this problem should vanish. Thanks in advance Markus -- For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much---the wheel, New York, wars and so on---while all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man---for precisely the same reasons. (Douglas Adams, The Hitchhikers Guide to the Galaxy.)
