[do apr 9 2009] [22:41:47] dberkholz those of you with a pet feature, feel
free to respond to the summary on -dev if you have some compelling reason why
it's super easy to get in and can't be pushed back. keep in mind there's no
reason we need to take forever for EAPI 4, either
pet feature: mtime preservation
supereasy: yes, this is already the current behavior of both portage and pkgcore
so nothing needs to be implemented here.
can't be pushed back: the mtime of to-be-installed files is currently
unspecified. Since the behavior of portage isn't changing nothing will break due
to this non-change, but it will make hacks that work around the package manager
(officially) obsolete and make it simpler to keep track of compiled code for
dynamic languages.
There is an extended proposal for changing only those mtimes that are too old or
too new (in the future). If that is indeed desirable this could be changed in
EAPI4, but it seems easy if not better/cleaner if mtime mangling is done on a
per-ebuild basis for those few that need it.
If the package manager preserves mtimes they can still easily be changed in
individual ebuilds.
However if the package manager does not preserve mtimes and they need to be
recovered, then the mtimes need to be saved at a point where mtimes have not yet
been mangled and then restored after the package manager is done with mtime
mangling. This is possible but the exact time of mangling would then need to be
specified. This is clearly a hack.
I know I personally asked for mtime preservation on 7-5-2008 on this list[1] and
the issue has surely existed even longer. Let's get rid of this problem already.
Thanks,
Marijn
