[Buildroot] [PATCH 0/7] Introduce the _AVAILABLE mechanism

[Buildroot] [PATCH 0/7] Introduce the _AVAILABLE mechanism

[Yann E. MORIN]

Hello All!

This patch series is an RFC for how to handle the _AVAILABLE symbol
in packages.

See this thread for the original proposal:
    http://lists.busybox.net/pipermail/buildroot/2012-August/057144.html

In this series, all packages are converted to use the _AVAILABLE symbol.
My reasoning behind this is that:

 1. all packages use the same mechanism, so they are consistent with
    each others
 2. modifying a package (ie. adding new dependencies) is easy, and does
    not require tracking down all dependant packages
 3. the dependencies of the comments "foo requires bar" are automatically
    updated in this case (although that's minor, and the comment themselves
    need updating)
 4. with the new script in patch 2, it's dirt-easy to add a new package
    using the _AVAILABLE mechanism

On the other hand, Arnout pointed out that only packages with depenencies on
toolchain features should be converted, and in cascade, packages that depend
on those, leaving alone packages that do not have any depednency at all (if
I understood correctly):
    http://lists.busybox.net/pipermail/buildroot/2012-August/058040.html

Of course, no need to say I'm in favor of modifying all packages, if at least
only for points 1&2 above. ;-) Of course, I understand Arnout's concerns about
keeping simplicity and not adding cruft where it is not needed. This post is
to request comments on this new deeply-impacting change.

So, back to the series as it is posted:

  - patch 1 updates the documentation to account for the _AVAILABLE
    mechanism. Because it can be tedious to review the changes in the
    documentation, I've temporarily put up a pre-rendered version on-line:
    http://ymorin.is-a-geek.org/download/tmp/br/pkg_avail/manual/manual.html

  - patch 2 introduces a new support/script/pkg-new script that asks a few
    questions to the user, and accordingly creates skeleton files for
    Config.in and foo.pkg. The doc is updated to document that script, and
    the pre-rendered version linked above contains that.

  - patch 3 adds a new support/scripts/pkg-avail script that does the dirty
    job of converting packages to the _AVAILABLE mechanism, and creates the
    next three patches:

  - patch 4 introduces the _AVAILABLE symbol for all packages, moves each
    package's 'depend on' to that new symbol, and for each package, adds a
    'depends on' on that new _AVAILABLE symbol. This is technically a no-op,
    dependencies are just moved to an intermediate symbol, but the _AVAILABLE
    symbol is not used by any other package;

  - patch 5 transforms all 'depends on' on a package into a 'depends on' the
    corresponding _AVAILABLE symbol, and for each such 'depends on', adds a
    select to the package's main symbol on the corresponding packages main
    symbols;

  - patch 6 checks that each 'select' on a package is guarded by a 'depends
    on' on the corresponding _AVAILABLE symbol;

  - patch 7 finally removes the now-useless support/scripts/pkg-avail,
    introduced in patch 3.


To be noted, the changes in patch 4 to 6 are purely mechanical, and will need
more review and manual tweaks before that series can be applied. Most notably,
having the gettext rework series [0] applied first would eliminate a large
class of corner-cases (eg. cases like: "select PKG_FOO if BLA"). Also, some
packages have 'select' on other package's options, and that needs to be
manually reviewed, as it's not easy to distinguish a package's option symbol
from a package symbol (eg. BR2_PACKAGE_UTIL_LINUX_MOUNT: is it a package named
'util-linux-mount', or is it the option 'mount' of a package named
'util-linux'?)

Again, this series is an _RFC_ on the _AVAILABLE mechanism, so the first
question we must answer is:

    Do we even want this mechanism in buildroot at all?

Then, and only then, can we decide what to do, and how far to push it.

Enjoy! ;-)

Regards,
Yann E. MORIN.

-rules:
+The +Config.in+ file for your package must also ensure that its
+dependencies are available. This is done in four steps:
 
-* Use a +select+ type of dependency for dependencies on
-  libraries. These dependencies are generally not obvious and it
-  therefore make sense to have the kconfig system ensure that the
-  dependencies are selected. For example, the _libgtk2_ package uses
-  +select BR2_PACKAGE_LIBGLIB2+ to make sure this library is also
-  enabled.
+1. The +BR2_PACKAGE_LIBFOO_AVAILABLE+ symbol shall +depends on+ any
+other package's +_AVAILABLE+ symbol. It may also depend on any other
+symbol, such as toolchain features, but should not directly depend on
+any package's main symbol.
 
-* Use a +depends on+ type of dependency when the user really needs to
-  be aware of the dependency. Typically, Buildroot uses this type of
-  dependency for dependencies on toolchain options (large file
-  support, RPC support, IPV6 support), or for dependencies on "big"
-  things, such as the X.org system. In some cases, especially
-  dependency on toolchain options, it is recommended to add a
-  +comment+ displayed when the option is not enabled, so that the user
-  knows why the package is not available.
+1. The main +BR2_PACKAGE_LIBFOO+ symbol should directly +depends
+on+ it's own +_AVAILABLE+ symbol, +BR2_PACKAGE_LIBFOO_AVAILABLE+, and
+should not depend on any other symbol.
 
-An example illustrates both the usage of +select+ and +depends on+.
+1. For each +_AVAILABLE+ symbol your package's own +_AVAILABLE+
+symbol depends on, your package's main symbol should +select+ the
+corresponding package's main symbol.
+
+1. Add a +comment+ briefly explaining why your package is not
+available. That +comment+ shall have a single negative dependency on
+your package's +_AVAILABLE+ symbol.
+
+The example below illustrates this mechanism for our libfoo package:

 --------------------------
 
+*Notes*
+
+* Even if your package does not have any dependency, you should anyway
+  add the corresponding +_AVAILABLE+ symbol. This way, other packages can
+  safely use the mechanism above to select your package, even if it is later
+  updated and dependencies are added (eg. a new version of the package is
+  released; or features, initially disabled, are now enabled...)
+
+* The symbols and the comment should be in this order, so that the
+  +menuconfig+ will be properly laid out.
+
+* The dependencies in +Config.in+ will make sure that your package's
+  dependencies options are also enabled, but they will not necessarily be
+  built before your package. To do so, these dependencies also need to be
+  expressed in the +.mk+ file of the package (see below).
 
-Note that these two dependency types are only transitive with the

+If your package can be fine-tuned, you can add sub-options, enclosed inside

  While you're at it, an automatic enable/disable example would

  We currently don't have a single range config option, and only one int.
So the example is a bit contrived...  If you add an extra example, a string
option that is qstripped in the .mk file is more appropriate.

  Overall, a very good addition to the doc, regardless of the _AVAILABLE stuff!

It's an 'int', so is not quoted in the .config.
(but I'll use a 'string' to address your other comment, so
I'll qstrip it.)

What do you mean by "automatic"?

Does this URL always match the latest version in the git tree?

Well, my opinion (FWIW) is those packages should not be treated
differently just because they are /big/.

(One of) the goal(s) of _AVAILABLE is to allow the user to say either:
  - I want this package, enable whatever dependencies are required.
or:
  - I need this package, but I have to provide a toolchain that has
    such and such feature

_AVAILABLE makes that easy.

Then, it's up to the user to understand what pulling-in a package implies.

  I'm not sure, but anyway we don't sync with the upstream kconfig very
often either.

  I actually agree, but that's not the current reality.

  OTOH, it makes sense to promote the wanted reality in the documentation.

Except that even with the _AVAILABLE feature, I don't know if we want
to change how we handle things like Python modules, X.org and so on. We
will pretty likely still want to hide all of the Python modules behind
a global Python option.

+Scripted new package
+--------------------
+
+To help you add your new package, Buildroot offers a script that partially
+automates the creation of a new package: +support/scripts/pkg-new+.
+
+When run, this script asks you a few questions about your package, and
+creates skeleton files for you, so you only have to fill-in the the values
+for the different variables.
+
+----
+$ ./support/script/pkg-new
+Name of the package: libfoo
+
+1) none
+2) multimedia
+3) java
+4) x11r7
+5) games
+Category of your package: 1
+
+1) autotools
+2) cmake
+3) generic
+Build-system your package is using: 1
+
+Your package skeleton files have been created; you can now edit these files
+to complete the creation of the package:
+  package/libfoo/Config.in
+  package/libfoo/libfoo.mk
+
+Do not forget to also edit 'package/Config.in' to include
+package/libfoo/Config.in in the correct location.
+----
+
+Then, you just have to edit the two generated files with appropriate values.
+Refer to the following sections for each type of build-system:
+
+* xref:generic-package-tutorial[]
+* xref:autotools-package-tutorial[]
+* xref:cmake-package-tutorial[]

[Buildroot] [PATCH] pkg-avail: make it work without stgit

[Thomas Petazzoni]

In order to make this script usable by more developers, make it work
without stgit. It supports a --mode=stgit option or a --mode=git
option. When using --mode=stgit, it will preserve its existing
behavior, when using --mode=git, it will simply make git commits
without fuzzing needlessly with stgit.

I still don't understand why people keep using stgit. I guess it's a
remnant of quilt-style workflow or something like that, because the
plain git, with its "git rebase -i" feature, allows to do exactly the
same thing, without having to use a separate tool. So people using
stgit should /really/ consider having a serious look at "git rebase
-i", and when they will see the light, they will wonder why for so
many years they have suffered in keeping their old-style quilt-looking
workflows.

Note: the --mode=stgit hasn't been tested after the changes.

It's not based on a branch, it's to be applied on top of the patch that
adds this script in the _AVAILABLE patch series.

You are right. This script should not depend on anything else than git.

That I use stgit behind the hood, when it is not a required tool imposed
by upstream, is my problem, and should be no concern for upstream.

I use stgit because I like the patch-queue semantic better, and I find it
much easier to work with, than the rebase semantic.

Also, what I am interested in, is getting changes upstream; that's my goal.
I am not interested in learning how to use *git* per-se: it is just a tool
to achieve that goal. If I can achieve the exact same goal by using the
much simpler stgit, then I'll use that, even if git is more powerful.

And no, I never used quilt before. And no, I am not suffering of using
stgit (quite the opposite, to be true). ;-)

Yann E. MORIN.

Well, you're the one who primarily uses this script to generate the
patches, and you'll be the one who will ultimately submit those
patches, so it sounds kind of natural that the script is adapted to
your workflow.

That said, I also wanted to be able to test your script, so I've just
adapted it to my own workflow. Since the modifications are fairly
trivial, I just thought I would share them.

  I would skip this question and always create it in packages/libfoo.  The
subdirectories are rare, we want to get rid of them, and anyway you can
easily move the generated directory to a different place after the fact.

  Does it have to be bash?  Hm, yes, for the arrays...  It would be better
if we can avoid relying on bash for new functionality.

  I don't think the indented Config.in block is very readable; I'd use a
plain <<_EOF_ with no extra indentation.  Then you can use cat after all.

  Same here, indentation doesn't look natural to me.

  For autotools-package and cmake-package, _CONF_OPT is also a very useful one.

  Maybe also add _INSTALL_STAGING.

  Putting a sample
	install -D -m 0644 $(@D)/... $(TARGET_DIR)/...
isn't a bad idea.

Agreed. However, I also wonder if it is a good idea to make this script
ask questions, as compared to a more conventional script that takes
command line arguments. But it's true that a script asking questions is
more like a wizard, probably easier to use.

Not sure I agree here. People too often do manual installation in
generic packages, while they should use 'make install', possibly after
tunning/patching the Makefile.

Best regards,

Indeed, the script is designed as a wizard for newbies, so they do not
find it too complex to add a new package, especially since the
_AVAILABLE stuff can be a bit misleading.

It's also meant for experts to quickly add a new package. For them, it
might be better to get the values from the arguments, rather than asking
questions, right. This script can be refined later for this use-case.

I've poundered this, too, but the script just an /implementation/ of the
documentation, so I think it should go last.

I'll check if I can make it a POSIX-compliant script.

Indenting here-documents allows one to easily see the end of it. I
personally have difficulties reading scripts where this is not the case.

I think we should fill-in only strictly-required variables.

I don't like it. This is just a skeleton file. No default value has been
provided for any variable.

Hmm. Maybe that's because my default tabstop is 4, not 8.
I just tried with 8, and it is indeed less readable.

Yet, I prefer that here-documents be indented rather than not.
I'll see to make it readable for tabstop=8.

[Buildroot] [PATCH 3/7] support/scripts: add a script to automate the migration to _AVAILABLE

[Yann E. MORIN]

This script runs three passes on the packages' Config.in files:

1) - introduces a BR2_PACKAGE_XXX_AVAILABLE symbol
   - moves all the package dependencies to this symbol
   - has the package depends only on this symbol

2) - transforms all 'depends on BR2_PACKAGE_XXX' into a dependency
     on the corresponding _AVAILABLE symbol
   - adds a select on the corresponding package

3) - checks and fixes 'select BR2_PACKAGE_XXX' that does not have a
     corresponding 'depends on BR2_PACKAGE_XXX_AVAILABLE'

NOTE: the coverage of this script is NOT 100%. Some manual inspection
and fixers are still required.

[Buildroot] [PATCH 4/7] packages: introduce the _AVAILABLE symbol to all packages

[Yann E. MORIN]

Introducing this symbol to all packages will allow other packages
to both safely select a package, and inherit its dependency.

Given two packages, the mechanism works as follow:

    ---8<---
    config BR2_PKG_FOO_AVAILABLE
    	depends on BR2_LARGEFILE

    config BR2_PKG_FOO
    	bool "foo"
    	depends on BR2_PKG_FOO_AVAILABLE
    ---8<---

    ---8<---
    config BR2_PKG_BAR_AVAILABLE
    	def_bool y
    	depends on BR2_PKG_FOO_AVAILABLE
    	depends on BR2_HAS_THREADS

    config BR2_PKG_BAR
        bool "bar"
    	depends on BR2_PKG_BAR_AVAILABLE
    	select BR2_PKG_FOO
    ---8<---

In this case, the 'select' on package 'foo' from package 'bar' is possible,
because package 'bar' inherits, via the BR2_PKG_BAR_AVAILABLE symbol, the
same dependencies as package 'foo'. So, package 'bar' can not be visible
if package 'foo' is not (although 'bar' may be hidden because of other
dependencies of its own, missing threads in the example).

This patch only introduces this new symbol for all packages, moves the
packages' dependencies to these new symbols, and makes each package depend
solely on this new symbol. Cross-package use of 'select' will be introduced
in a later patch.

With the construct above, using 'select' is now safe.

[Buildroot] [PATCH 5/7] packages: use the newly-introduced _AVAILABLE symbol

[Yann E. MORIN]

This patch transforms all 'depends on' on a package to a 'depends on'
the corresponding _AVAILABLE symbol, and adds a 'select' against the
dependant package.

Sorry for not getting back to you earlier about this.

I am definitely in favour of this, and I'm really impressed by the
methodology you've used to achieve this. I will post a few comments as
replies to the individual patches with minor things.

However, I'd like you to update us on what are the remaining issues to
be solved before being able to commit this (of course, the script needs
to be re-executed to update all packages that have changed since you
posted the patch series, but you seemed to mention other issues as
well, gettext and maybe others).

Yes, we want this mechanism. Anyone trying to solve
http://autobuild.buildroot.org/results/3eaadd2365d60f574ba8daef45b34370cc5c6272/build-end.log
would agree with this change. I agree that it makes the simple package
slightly more complicated, but not too much, so it sounds to me like it
is a reasonable trade-off.

Ok, I noted three "problems", that I think will have to fixed manually.

Problem 1: recursive dependencies introduced
============================================

Running 'make menuconfig', I get:

package/multimedia/gstreamer/Config.in:6:	symbol BR2_PACKAGE_GSTREAMER is selected by BR2_PACKAGE_GST_PLUGINS_BASE

Looking at the first one, it seems to be caused by the fact that all
Python external packages are enclosed inside a "if BR2_PACKAGE_PYTHON"
in package/Config.in, so this Python dependency is already available.

I think this problem can only be solved with manual intervention.

Problem 2: incorrect addition of dependencies on package sub-options
====================================================================

In package/python-dpkt/Config.in, your script generates:

 config BR2_PACKAGE_PYTHON_DPKT_AVAILABLE
        def_bool y
        depends on BR2_PACKAGE_PYTHON_AVAILABLE
        depends on BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE

But the last line shouldn't be there. BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE
doesn't exist: BR2_PACKAGE_PYTHON_ZLIB is a sub-option of the python
package.

On the other hand, the sub-option are lacking the addition of "depends
on ..._AVAILABLE", for example in package/python/Config.in:

 config BR2_PACKAGE_PYTHON_ZLIB
        bool "zlib module"
        select BR2_PACKAGE_ZLIB
        help
          zlib support in Python

this should become:

 config BR2_PACKAGE_PYTHON_ZLIB
        bool "zlib module"
        select BR2_PACKAGE_ZLIB
+       depends on BR2_PACKAGE_ZLIB_AVAILABLE
        help
          zlib support in Python

But then in that case, we should also have a
BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE symbol, so that python-dpkt can
depend on it instead of forcefully selecting BR2_PACKAGE_PYTHON_ZLIB,
without knowing if zlib is available or not.

This problem however is going to be present in many many places, so I
don't know if manual intervention is reasonable for it. But on the
other hand, I am not sure it is possible to write an automated script
to solve this problem.

Problem 3: removing legacy
==========================

Due to the absence of such a _AVAILABLE mechanism, we have added a lot
of "depends on" in many packages that would now become useless. Take
for example libgtk2:

config BR2_PACKAGE_LIBGTK2_AVAILABLE
        def_bool y
        depends on BR2_PACKAGE_XORG7||BR2_PACKAGE_DIRECTFB
        depends on BR2_USE_WCHAR # glib2
        depends on BR2_INSTALL_LIBSTDCPP # pango
	[...]

Those last two "depends on" are now useless, because those dependencies
are automatically provided by the depends on CAIRO_AVAILABLE and
LIBGLIB2_AVAILABLE.

So those legacy dependencies should be removed.

Here, I don't think an automated process is possible, a human
intervention will be needed to find out if those legacy dependencies
can be removed or not, on a case by case basis.

So all in all, the problem I'm most worried about is problem (2). Have
you thought about it already?

Strange. I do not recall all those recursive deps issues. I'll check here.

My gut feeling is that the "if BR2_PACKAGE_PYTHON" should go, now that
we have _AVAILABLE.

As much as I remember, there were not so much cases like that. But, except
for manual intervention, I do not see how we could differentiate that case.

The problem is (form my script's point of view): 
  Is BR2_PACKAGE_PYTHON_ZLIB representing:
    - the package "python-zlib", or
    - the option "zlib" of the package "python"?

Except for intrumenting the option symbol (eg.: BR2_PACKAGE_PYTHON_OPT_ZLIB)
which I doubt we want to, there is no easy way for the script to detect
this situation.

And then, do we want to push the _AVAILABLE semantic dow to sub-option?
I doubt we do.

So, depending on sub-options should be as:

config BR2_PACKAGE_PYTHON_DPKT_AVAILABLE
    def_bool y
    depends on BR2_PACKAGE_PYTHON_AVAILABLE
    depends on BR2_PACKAGE_PYTHON_ZLIB # Sub-option

Yep, manual intervention, one of the corener-cases I wrote about in my
intro mail.

Yep, I've thought about it. Answer: manual review.
( Don't worry, *I* will have to do it before I submit a final series! ;-) )

Unfortunately this is not what we want:

 * We want the python-dpkt package to be visible to the user only if
   Python (BR2_PACKAGE_PYTHON) has been enabled;

 * However, when one enables BR2_PACKAGE_PYTHON, we want the
   python-dpkt package to be visible even if the
   BR2_PACKAGE_PYTHON_ZLIB option is not selected, and we want this
   option to be automatically enabled when the user enables the
   python-dpkt package. However, we have to be careful not to show the
   python-dpkt option if for some reason the BR2_PACKAGE_PYTHON_ZLIB
   option cannot be selected due to a dependency that isn't available
   (in our zlib is available on all architectures, but we could imagine
   depending on, say, libfoobar that is only available on certain
   architectures)

The reasoning is that:

 * We can assume that a user knows that the Python interpreter should

Ok.

So, for me, problem (2) remains unsolved at the moment. I guess the
only solution is to add _AVAILABLE kconfig knobs for all the package
sub-options that select other packages. But this means adding a lot
more _AVAILABLE knobs than we initially thought.

  Someone (I don't remember who) proposed to stop doing that, because it adds
little value.  Indeed, it's not as if 9 extra entries in the Scripting
Languages menu will suddenly make it more difficult to navigate.  Maybe X.org
is an exception, but even there most packages are collected in the x11r7 menus
(and those could still be kept in a conditional).

  Originally I was in favour of having the BR2_PACKAGE_PYTHON conditionals,
but it _would_ probably make life simpler if we only had dependencies on
toolchain options...

  Yann, what do you think, would it make suboption handling simpler if there
was no 'depends on BR2_PACKAGE_PYTHON'?

In fact, I think python modules _should_ depends on BR2_PACKAGE_PYTHON, and
that should be more easily handled when _AVAILABLE is, well, available.

The problem with python modules is that they are hidden behind a
    if BR2_PACKAGE_PYTHON
    source [python-modules]
    endif
*in* *addition* *of*, for each package:
    depends on BR2_PACKAGE_PYTHON

I think the "if BR2_PACKAGE_PYTHON" should be removed, and we should keep
only the per-package depends on. If/when we add _AVAILABLE, it will be
easier to manage.

Yes, that will add more entries in the menuconfig. But that's not as it were
not already a bit crowded... ;-) And it can go in a sub-menu, anyway, like:

    Interpreters  --->
        Python support  --->
           [ ] Python
           External python modules  --->
               [ ] Foo

When you select python:

    Interpreters  --->
        Python support  --->
           [*] Python
           python module format (.pyc only)
           Core python modules  --->
               [ ] Bar
           External python modules  --->
               [ ] Foo

And when you select Foo:

    Interpreters  --->
        Python support  --->
           -*- Python
           python module format (.pyc only)
           Core python modules  --->
               [ ] Bar
           External python modules  --->
               [*] Foo


The most problematic issue I've encountered is with X11r7. The top-level
config option is BR2_PACKAGE_XORG7, but it is *not* a package.

What I would suggest is something like (just out of my tired brain):

    choice
        prompt "X Window System server type"

    config BR2_PACKAGE_XSERVER_none
        bool "None"
    
    config BR2_PACKAGE_XSERVER_xorg  # <-- Note how it currently is lower-case
        bool "Modular X.org"         #     'xorg' in the repository...
        depends on BR2_PACKAGE_XSERVER_xorg_AVAILABLE
        select BR2_HAS_XORG7
    
    comment 'X.org requires largefile and C++ support'
        depends on !BR2_PACKAGE_XSERVER_xorg_AVAILABLE
    
    config BR2_PACKAGE_XSERVER_tinyx  # <-- Ditto lower-case 'tinyx'...
        bool "TinyX"
        depends on BR2_PACKAGE_XSERVER_tinyx_AVAILABLE
        select BR2_HAS_XORG7
    
    comment 'TinyX depends on BLABLA'
        depends on !BR2_PACKAGE_XSERVER_xorg_AVAILABLE
    
    endchoice

    config BR2_HAS_XORG7
        bool

    menu "Xorg7 libs and apps"
    source "package/Xfoo/Config.in"
    # source other packages, too
    endmenu

And then in package Xfoo:

    config BR2_PACKAGE_XFOO_AVAILABLE
        def_bool y
        depends on BR2_HAS_XORG7
        depends on BR2_PACKAGE_BAR_AVAILABLE

    comment "Package Xfoo requires an Xserver"
        depends on !BR2_PACKAGE_XFOO_AVAILABLE

    config BR2_PACKAGE_XFOO
        bool "Xfoo"
        depends on BR2_PACKAGE_XFOO_AVAILABLE
        select BR2_PACKAGE_BAR

And so on...

Of course, it goes against the mantra:
    I know I want package 'Xfoo', just select whatever
    I need to get it, for ${DEITY_NAME}'s sake!

It should probably be possible to keep that semantic, yet with a bit more
involvement.

Comments?

  I don't see what is the problem with that.  USE_WCHAR is also not a package.
Except maybe the name is inconvenient.

  Actually, the XSERVER_tinyx/xorg option is wrongly placed: it should be
a sub-option of BR2_PACKAGE_XSERVER_XORG_SERVER.  The choice has no real
effect unless BR2_PACKAGE_XSERVER_XORG_SERVER is also selected (and all
the xorg-server modules select the xorg-server).  But that's a wholly
different story.

The real problem with _AVAILABLE is not caused by Python/X.org packages
being under a big "if" condition. The big problem we hadn't really seen
is that we don't only need to add _AVAILABLE options for each package,
but also for each package sub-options that does a select on another
package. This means that the number of _AVAILABLE kconfig options to
add is a lot bigger than we expected, at a point that probably makes
the _AVAILABLE solution relatively impractical.

Maybe the solution would be that we do not add _AVAILABLE to sub-options,
but we can still use it from sub-options. Eg. (condensed):

    config PKG_FOO_AVAIL
        def_bool y
        depends on blabla

    config PKG_FOO
        bool "package foo"
        depends on PKG_FOO_AVAIL
        select blabla

    config PKG_BAR_AVAIL
        def_bool y
        depends on booboo

    config PKG_BAR
        bool "package bar"
        depends on PKG_BAR_AVAIL
        select booboo

    if PKG_BAR

    config PKG_BAR_OPTION
        bool "bar's option"
        depends on PKG_FOO_AVAIL
        select PKG_FOO

    comment "bar's option needs package foo"
        depends on !PKG_FOO_AVAIL

    endif # PKG_BAR

Isn't that sufficient?

For python's external modules, we should treat them as normal packages that
"depends on BR2_PACKAGE_PYTHON_AVAILABLE" and "select BR2_PACKAGE_PYTHON".

Dito for the Xorg's packages, except it's a bit different because the
BR2_PACKAGE_XORG7 symbol does *not* represent a package (see my previous
mail for a proposed change).

From a quick review, it sounds sufficient indeed. What surprises me is
why we didn't think about this solution the other day when discussing
your _AVAILABLE patch set.

To be honest, I'm surprised too I did not think about it. ;-]

In fact, as an after-thought, I do know why. That's because I was thinking
the other way-around: a package that depends on a sub-option of another
package, sub-option which in turn depends on a third package.  *That* one
would require an _AVAILABLE for sub-options.

For example, libuuid which is a sub-option of util-linux (although that one
sub-option has no dpendency; but you get the idea) is select by a few other
packages (eg. parted, ntfs-3g...).

And going *that* route is IMHO not what we want.

And first, we need to know if the case really exists (I was not able to
find a good heuristic to find such a case with a simple grep, so I gave
up the search).

Yann E. MORIN.

Our example was the one of python-dpkt, which was doing a:

	depends on BR2_PACKAGE_PYTHON
	select BR2_PACKAGE_PYTHON_ZLIB

or BR2_PACKAGE_PYTHON_ZLIB is not a package per-se, but a sub-option of
the python package. And this this sub-option does a select, we should
introduce a BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE, I don't see a way around
it.

Except modifying kconfig, as we discussed, of course...

  It is still possible to add an _AVAILABLE for sub-options that need them.
For something like a python module, it does make sense have an _AVAILABLE
for the sub-option.  Similar for GStreamer modules using an external library.
These things can be considered a separate (micro)package, in some sense.

  If the script converts the python-dpkt example above into
	depends on BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE
	select BR2_PACKAGE_PYTHON_ZLIB
won't kconfig detect that PYTHON_ZLIB_AVAILABLE doesn't exist?  Then it
will be easy enough to fix those suboptions manually (if there aren't too
many of them...).

  With the pkg-new script, my concern is much reduced.  The simplicity of having
the same pattern all over wins out in that case.

  There is still an alternative: patch Kconfig to "properly" handle
select/depend transitivity.  I.e., when a symbol selects another symbol,
this implies that all dependencies of the other symbol are inherited.  Did
anyone ever investigate the feasibility of such an feature?

OK. Did you have a look at it? Does it fit your use-case? What would
be missing? (Note: it's still a little bare, and would probably do with
a little bit of enhancements, but at least proves the point that it is
possible to help adding new packages.)

Yes. Both Thomas and I have had a look (but separately). I got an headache
each time I tried to understand the kconfig code. IIRC, Thomas' experience
was a bit in the same vein.

My point of view is that we must consider (unless proven otherwise) that
modifying kconfig to handle this select/depends mess is not possible.

If it were to be the case, then the change should go upstream (eg. the
Linux kernel) for review first, and then we should lobby for it to be
included there, before we should even try to use it.

But until then, lets consider this to be a limitation in kconfig that we
have no possibiliy to overcome in kconfig itself.

With this in mind, I think the _AVAILABLE stuff (or any other alternate
solution that still has to emerge) is the way to go.

Let me also add this:

This is a change is the kconfig semantics, and will probably be a little
bit difficult to make it accepted upstream, unless the solution is also
usefull for the Linux kernel, which has gone to great lengths to avoid
this very situation for many years now.

So, I would not count in such a change to be in a futur kernel in the
foreseeable futur.

Yann E. MORIN.

  I completely agree.  But if it had been easy to do, it might have been
preferable over adding verbosity to Config.in.

  In that case, I guess I'll have to take the time to review those patches
before Saturday :-)

  Arnout

I am supposed to send an updated series tomorrow evening.
"Supposed to", that's the problematic phrase in this sentence.

I am late. So late.

But on the other hand, this new series would not be very different from
the last I sent, so I wonder if it really makes sense to re-post.

But, I want to send an email that sums up the state of the change:
  - for the series as it is:
    - what's been done
    - where there are issues
    - what's left to do
  - for future work:
    - options dependening on another package
    - package depending on option of another package
    - ...

Yann E. MORIN.
