Hi,

Whilst working on the Reproducible Builds effort [0] we noticed
that musescore-snapshot could not be built reproducibly.

This is because it generated a zip file without normalising the
umask(2):

Hi Chris,

I know, src:musescore has the same problem, it will be addressed
in the next upload, as I don’t know what upstream will do yet.

>Patch attached.

That patch won’t work, cmake tar has no --long-options suitable
for what you’re trying to do. I’ve committed 56fe1387 as my
attempt at solving it in the packaging, for now, but haven’t
gotten around to testing it yet.

bye,

Huh, it appeared to work for me so I wonder what was wrong with my
testcase. Anyway, I defer to thee. :)

To potentially save others a few moments also finding a link, this is:

Hi Chris,

oh, interesting… I’ve been told that cmake has a tar builtin,
which doesn’t do these options… perhaps it calls out to the
system-wide tar if one exists (in which case the patch is not
upstreamable).

I’ll have a look when I have the time.

Thanks,

<diogenese> Beware of ritual lest you forget the meaning behind it.
<igli> yeah but it means if you really care about something, don't
    ritualise it, or you will lose it. don't fetishise it, don't
    obsess. or you'll forget why you love it in the first place.

Ahh, I see:

> perhaps it calls out to the system-wide tar if one exists

Seems unlikely, alas. :(
