[gentoo-dev] RFC: Making largefile a global use

Hi,

there are not many packages using it, but I will add this flag to
another 10.
And I think, it is of a general, global meaning. Do you agree in making
it a global USE?

i cant see much value anymore in even making this an option.  just drop the 
USE flag and always use LFS.

Just a users opinion.

I read about this on the wiki to be sure it was what I thought it was.  
Isn't this the default about everywhere else?  I agree with Mike, why 
not just turn it on as a default setting?

I'm new here, but I think it would be good idea to list packages using
that flag with meaning described by its maintainers and your proposal.

 euse -i largefile
global use flags (searching: largefile)
************************************************************
no matching entries found

local use flags (searching: largefile)
************************************************************
[+ C  ] largefile (app-text/dos2unix):

The sci packages and dos2unix are under my control.
Others are maintained by net-p2p@gentoo.org, hwoarang@gentoo.org,
volkmar@gentoo.org & freedesktop-bugs@gentoo.org.

And will add it or not to all sci-biology/{emboss,ambassy} packages.

But I would agree with Mike in defaulting to LFS.

For the record: eggdbus was merged into glib itself as gdbus, and
almost nothing needs it anymore. It'll be removed as soon as
libgnome-keyring-2.32.0 and polkit-0.99-r1 become stable on all
arches.

Why?

Please remember that largefile doesn't just mean files bigger than 4GiB,
it enables more than just sizeof(off_t)==8, it is also required to
access data on huge filesystems (that right now are not enabled to be
generated by anything, but still).

I don't think at all that largefile should be an option; if something
has trouble working with largefile it should be fixed, not conditioned.

just because upstream has this configure flag. but it seems we agree on
removing the flag completely, defaulting on largefile support and fixing
what needs a fix.
Correct?

Correct. Any configure with AC_SYS_LARGEFILE will get a
--enable-largefile option, but if you grep through the tree, this is
usually simply added unconditionally.

It is more interesting to see whether it actually supports LFS entirely;
quite a few packages forget to include config.h in some file or other,
and cause mixed LFS and non-LFS syscalls to be used, which is bad. I
have written an utility as part of Ruby-Elf[1] called verify-lfs that is
designed to check for that.

Also note that largefile has no meaning on most 64-bit arches (AMD64 for
sure, I guess the others as well).

Is there any value adding --enable-largefile? autoconf macros have it
enabled by default.

developers need not go through the source and manually verify that the
package is using AC_SYS_LARGEFILE and is enabled by default ?

+1 on forcing it always on. gpgme already requires all packages linked
against it to use same largefile switch value as it does,
and maintaining the ability to switch it on/off just creates more
trouble than profit.

The only use case I see for the explicit switch possibility
are the dependencies of -bin packages.
