[gentoo-dev] Packages that explicitly DEPEND on sys-apps/sed

[gentoo-dev] Packages that explicitly DEPEND on sys-apps/sed

[Jeroen Roovers]

Judging from [1], a couple of thousands of ebuilds DEPEND on
sys-apps/sed, which is a system package (in profiles/base/packages)
since at least 2004. It boils down to some 2535 ebuilds, 1409 packages
and 14 eclasses, some requiring a version as high as 4.0.5, which went
stable in 2003.

What do you say. Do we keep them or prune them from the tree?

To follow up on that, some 496 ebuilds explicitly DEPEND on
sys-apps/sed, with only a few apparently needing 4.1.5 and just the one
seemingly requiring 4.2 (though it isn't obvious from the actual sed
invocation). I haven't checked which of those RDEPEND on sys-apps/sed
too, but it shouldn't be many. That means some two thousand acquire
this DEPEND from an eclass, so for the majority of packages, this
redundancy could be easily fixed, while the rest of them would probably
keep inspiring developers new and old to keep introducing the dep or
indeed be insecure about removing it.

 Since sys-apps/sed is a system package, I would vote for removing the
 dependency from the ebuilds/eclasses.

The implicit system set dependency thing really, really needs to die; 
at the time of the rule, portage couldn't handle resolving graphs of 
that sort.  PM resolvers for gentoo are generally a fair bit saner 
now thus doing what you're suggesting isn't really beneficial (frankly 
it causes some issues for stages, as zac noted).

I fixed that implicit system depend rule[1] in devmanual some year ago
to mention there are exceptions and leaving them out might break
building order... "Note that this rule also needs consideration for
packages like", "break building order", ...

But I'm fine with making it even more clear if that doesn't make the
case as is

It seems to me that the best policy would be for every package to just
list all its dependencies, and then users are free to run the default
experience that includes everything in @system, or a more trimmed-down
experience.  Plus, from time to time there is some debate about
removing some package from @system and the only way to figure out what
it breaks is a long discussion on -dev and lots of tinderbox testing,
and then lots of ebuilds being modified to add the dependency back in.
 With explicit dependencies it is trivial to determine.

And no, I don't think that Gentoo should fully support reduced-@system
builds, but there is no harm in making them more of a viable option.

An annoying, but valid complaint agains this is that the deps start 
getting heavy to maintain for developers, and aren't always viable to 
represent.  Unpackers for example, are a pain in the ass for current 
EAPIs- that could be reduced in pain via addition of basic implicit 
deps to EAPI5 (if a src_uri ends in .bz2, then dep on virtual/bzip2).

Or devs could just be nudged into adding the appropriate DEPEND.  
repoman checking for it either way wouldn't be hard.

The trickier point is gcc, but in my view, that's where we get the 
most gain- if the toolchain is represented in the deps it makes 
integrated cross compilation easier (keyword is integrated; crossdev 
already makes it reasonably straightforward I realize).

It also improves -e behaviour; instead of the resolver being hardcoded 
to try promoting certain things (glibc and friends mainly), the 
resolver's normal logic can be used there.

Personally... I think gentoo should aim for it actually.  Question is 
how close we can get to it w/out overly burdening developers.

Don't suppose someone has interest in looking into this?

i think you vastly underestimate how bad this is.  what you're proposing is 
the majority list:
	sys-apps/baselayout (after all, it provides / /usr /usr/share /etc)
	app-shells/bash
	sys-apps/coreutils
	sys-apps/gawk
	sys-apps/grep
	sys-apps/sed (every autotooled package uses it)
	sys-apps/which (g'luck tracking down all the consumers)
	sys-devel/gcc
	sys-devel/binutils
	virtual/libc
	sys-apps/make

requiring people to remember to use these deps if their ebuild happens to 
execute them is silly:
	sys-apps/diffutils (provides `patch` after all)
	sys-apps/findutils

archiving/compression deps absolutely need to be in the PM.  otherwise you're 
talking about:
	app-arch/tar (a quick count shows 22k ebuilds need it out of all 27k)
	app-arch/gzip (14k ebuilds)
	app-arch/bzip2 (8k ebuilds)

these are mostly done already via the autotools eclass, so these should get 
dropped from system:
	sys-devel/autoconf
	sys-devel/automake
	sys-devel/libtool
	sys-devel/m4

i dont understand this at all.  sounds to me like this complicates cross-
compilation unnecessarily.

That last comment, on the autotools eclass, suggests a solution, a 
basedeps eclass, which most ebuilds could simply inherit.

The eclass could handle most archiving dependencies automatically, using 
source URL extensions to determine type.  Similarly with stuff like make 
by scanning for calls to it or emake.  Bash and baselayout would be 
mandatory, and variables could be used for quick-list adds and overrides.

It'd take a LOT of work and testing and may even then not be workable 
unless implemented as an arbitrary list that pretty much simply moves the 
@system list from its current location into an eclass, but the idea's 
interesting.  Possible/practical or wishful thinking?

that's not what i was suggesting at all, nor do i think it feasible

the automatic code scanning wouldnt work as it would need to consider the 
default implementation of functions (which really only the PM knows), and even 
then it cant handle code which is dynamic (like the default PM funcs).
	if [ -e Makefile ] ; then emake ; fi

how do you automatically detect utilities that only the package executes ?

gee, that sounds exactly like the system set we already have, except this 
solution generates a lot more overhead (all the execution/caching required to 
process this new eclass), and more pains.  the system set is in the profile 
which other profiles can easily override (by design).  much harder to pull 
that off with eclasses.

impractical wishful thinking

further, many of these deps themselves depend on their own existence.  
coreutils needs expr/touch/tail/head/...... which coreutils provides.  bash 
needs a shell which bash provides.  sed needs sed which sed provides.  gawk 
needs gawk which gawk provides.  make needs make which make provides.

friends also need their friends.  make/bash/sed/grep/coreutils pretty much all 
need each other.  which is another reason why they're in the system set.

[-- Attachment #1: Type: Text/Plain, Size: 1113 bytes --]

more thoughts as to why this is a bad idea ... how do you deal with runtime 
library requirements which only the compiler knows about ?  sys-devel/gcc 
provides many runtime libraries such as libgcc_s.so.  but whether the package 
actually needs that at runtime may depend purely on the arch/abi, or what code 
*just happens* to be generated.  embedded cpus tend to need it more often than 
desktop cpus because libgcc_s.so provides fun things like 64bit multiplication 
and division routines when the hardware lacks support.  so if your target 
happens to do 64bit multiplication, you now have RDEPEND on sys-devel/gcc.

glibc itself will load up libgcc_s.so via dlopen when unwinding in threaded 
situations.  but this only necessary when the package uses threads, and needs 
unwind support (iirc), and glibc is using NPTL.  you could say "ah just have 
glibc itself always require gcc", but if we're not being explicit in our deps, 
i dont see any difference from the implicit system set (except in the "worse" 
direction).

these dependencies cannot be expressed via ebuilds/eclasses.

I always thought of @system as providing a POSIX-compatible userland,
exactly so that deps wouldn't need to be listed. eg every POSIX compatible
system has to have find, sed etc[1] and of course ed which is missing,
annoyingly enough for scripting.

With regard to having a slimmed-down @system it might appear to make sense
to look at moving to only allowing POSIX options, testing perhaps with
sys-apps/minised[2] (assuming we'd have a virtual in @system) which I
haven't tried. AIUI however there's far too many sed GNUisms to go down
that road.

Even on FreeBSD they're still using gsed; the fact that people will not stop
using GNU-style regexes-- and that they need it for their own base system--
is only driving them to work on including the same extensions in their own
software.[3]

Given that we're not about to clear the GNUisms from the tree, it's been "a
system package since at least 2004" with dependencies on versions "as high
as 4.0.5, which went stable in 2003" I'd concur that the existing ebuild/
eclass dependencies should be trimmed as and when, if it can't be
automated.

Hopefully at some point there'll be another implementation with the same or
similar capabilities, which might even make it into POSIX. Until then it
would appear Gentoo needs gsed just like it needs bash, afaict. An embedded
system might well have a different profile; presumably applications would
not be built on the target tho.

we've already discussed POSIX strictness in the tree multiple times, and it's 
been shot down multiple times for good reason.  GNU extensions make life a 
hell of a lot easier, the majority of people are developing/testing on such 
systems (Linux with GNU userland), and the burden on other ports is trivial if 
not negligible.  let's stop kicking this horse as we're at the glue stage now.

OK, right, so where are we heading with this? sys-apps/sed is in system
and it's bound to be >=sed-4 and we're sticking with it. So are we
going to get rid of it in all the ebuilds that still set that dep?

for the packages that just depend on raw sed, it should most likely be 
dropped.  for those depending on a newer version, they're probably doing it 
because they dont work with an older one, and those cant be dropped until our 
system set forces a new enough sed.  the base profile only requires "sys-
apps/sed" atm, so that'd probably need updating to read ">=sys-apps/sed-4".

IMHO a big distinction between DEPEND and RDEPEND should be done.

For RDEPEND all dependencies should be listed (including those packages
provided by @system)
This would allow easy installing into chroots with package manager's
help, especially in combination with binary packages.

For DEPEND it could be sufficient to assume @system is present or at
least limit to those dependencies needed by the package/ebuild itself,
but not those coming implicitly with features of package manager used
(e.g. default unpacking, emake, einstall, do*)
Eclasses "extending" package manager features should include their extra
DEPEND needs.


On the other hand, it would be nice if package manager could auto-detect
at least part of the runtime dependencies (library linking should be easy
as package manager already looks for them -- what's completely missing
is shebang/interpreter dependencies).
This way only version constraints would need to get added to RDEPEND
inside ebuilds as needed (and the few cases where dlopen makes it
impossible for package manager to see the linking).

A nice benefit of this would be that it can adapt to changes caused by
INSTALL_MASK, e.g. reduces dependencies that are not needed anymore
because some files were not installed.

Where this has been most useful for me is when I'm building out a 
minimal system (e.g., a diskless terminal or cluster node) using 
ROOT=/somewhere/else. It's nice to just start emerging stuff there 
instead of having to unpack a stage1 or something first.

I wonder if we need another set that's really @base (truly minimal, like 
what Mike posted elsewhere), so @system would then serve as what we 
think is necessary for a running Gentoo installation.

On a related note that would accomplish similar purposes, it would also 
be nice if we could somehow discriminate between DEPEND and RDEPEND for 
@system packages so build-only deps could be removed.

It's worth noting that stage1 and stage2 tarballs do not contain full
system sets. Therefore, we can't assume that sys-apps/sed will be
included in those stages unless we use something other than the system
set to pull it into the stage1. A couple of possible a solutions are:

A) Modify $PORTDIR/scripts/bootstrap.sh to ensure that sed is installed
in stage1.

B) Keep a sys-apps/sed dependency in the sys-apps/portage ebuilds, so
that bootstrap.sh will pull sed into stage1 as a dependency of
sys-apps/portage.
