Refactor build directory setting into separate method and solve a few bugs.
* Move setting of new build directory from constructor to _set_builddir()
method including detection if directory (current or source) it should be
relative to.
* Even if a new build directory was specified, detect if it matches the source
directory and unset it in such a case.
* Use _set_builddir() in enforce_out_of_source_tree() methods. Previous
implementation didn't handle default build directory properly (i.e.
relativeness to current or source directory).
Implement source directory switching support (Closes: #530597).
* New optional option --sourcedirectory/-d.
* New Buildsystem API methods for getting source directory/path
(since sourcedir may no longer be topdir), source 2 build
directory convertions, doit_in_sourcedir() etc.
* clean_builddir() -> rmdir_builddir() rename.
--list all buildsystems (including all 3rd party ones) dynamically.
* Implement a new sub in Dh_Buildsystems (load_all_buildsystems()) which
dynamically tries to find all buildsystem class files in perl module
directories (@INC) and clearly marks third party buildsystems as such.
* Use this sub for listing buildsystems so now --list easily helps a user
discover *all* buildsystem classes installed on his/her system clearly
separating built-in ones from third party ones.
Improvements in DH_OPTIONS handling and DH_AUTO_OPTIONS envvar support.
* DH_AUTO_OPTIONS is like existing DH_OPTIONS, just only for dh_auto
stuff. This also avoids "explosion" of separate DH_AUTO_* environment
variables (i.e. exports in debian/rules) and encourages usage of dh_auto
command line option names. DH_AUTO_OPTIONS is passed via "extra_args" to
Dh_Lib::init() (API addition).
* When splitting options from DH_OPTIONS and its flavours, allow arguments
to include whitespaces if they are escaped with backslash (\) (see
split_options_string()). Document this in debhelper.pod.
* Short option for --buildsystem is -c (aka class).
* Provide API to cancel option specs from default debhelper options.
It will be used in the feature.
Use term "out of source" rather than "outside source".
* "out of source" or "out of source tree" seems to be more popular
term to describe building in the builddir.
* Avoid using hyphens in both "out of source" and "in source" terms.

dh_auto_configure: Pass packlist=0 when running Makefile.PL, in case it is a Build.PL passthru, to avoid it creating the .packlist file. Closes: #527990
remove verbose_print of buildsystem selection details
This would be the only place in debhelper where -v enables debugging info
that is not just shell commands being run.
Since --list can be used to see details of build system selection, and
since it will probably be obvious which one is selected in -v mode due to
the commands run, I think this oddity is unnecessary.
_mkdir is not necessary, because mkdir's error messages are good enough
if a file by the name of the directory exists ("cannot create directory: File
exists"), or if a file is where the parent directory should be ("cannot
create directory: Not a directory")
Using mkdir -p seems useful, in case someone wants a deeply nested
builddir.
This also changes the return value of mkdir_builddir, but nothing currently
tests it.
* New feature - when listing buildsystems, list their status too
(auto/specified).
* Dh_Buildsystem_Basic.pm renamed to Dh_Buildsystem.pm
* Addressed a few issues expressed in the comments, answered a few
comments.
* Cache DEB_BUILD_GNU_TYPE value. Performance hit is noticable when
listing build systems.
* is_auto_buildable() renamed to check_auto_buildable() (again).
Since there is is_buildable() now, I didn't want to use is_ for
that method.
* Dh_Buildsystem_Option dropped and Dh_Buildsystem_Chdir functionality
partitially merged into Dh_Buildsystem_Basic. Dh_Buildsystem_Bases.pm
renamed to Dh_Buildsystem_Basic.pm to match classname.
* *_impl() ditched completely. Previous {configure,build,test,install,clean}_impl()
renamed to just configure(), build(), test(), install(), clean() instead.
Added pre_action($action) and post_action($action) hooks instead which are called
by Dh_Buildsystems::buildsystems_do().
* Builddir is handled via mkdir_builddir(), doit_in_buildddir(), clean_builddir()
methods which buildsystems should call directly. Removed get_top* method, added
get_rel2builddir_path().
* is_buildable() method renamed to is_auto_buildable() to reflect its
purpose more.
* ::perl_makefile renamed to ::perl_makemaker and which is based on ::makefile
now. MakeMaker hack moved from ::makefile to ::perl_makemaker where it belongs
(thanks for the tip).
* Dh_Buildsystems refactored into a simple perl module rather than OO class and
simplified a bit.
* @BUILDSYSTEMS and is_auto_buildable() modified to 100% match historical order.
TODO: user documentation (e.g. DH_AUTO_BUILDDIRECTORY and DH_AUTO_BUILDSYSTEM
environment variables and common dh_auto_* options (--buildsystem and --builddirectory)).
Current plugin inheritance hierarchy is like this:
A manager module for buildsystem "plugins". It deals with the following tasks:
* Handles common command line and environment options. As currently implemented
by the patch they are:
- DH_AUTO_BUILDSYSTEM envvar, -m/--build-system - disables autoguessing of
the build system and allows the user to specify which one to use.
- DH_AUTO_BUILDDIRECTORY envvar, -b/--build-directory - option to enable
building outside source if supported by the buildsystem. User can specify
the build directory name or let it be autogenerated (currently
"obj-`dpkg_architecture('DEB_BUILD_GNU_TYPE')`" as per CDBS convention).
Outside source building has an advantage of avoiding sourcedir pollution
which the clean routine cannot deal with properly (at least common in
cmake or autotools case). The "clean" is simple in such a case - just
rm -rf builddir.
- -l/--list - lists all buildsystems known to Dh_Buildsystems along with
their descriptions.
* Manages buildsystem plugins:
- provides a way to list them and collect information about them.
- provides a way to force loading & use of a specific buildsystem.
- determines which build system is applicable to the source in question using
common API (::is_buildable() method) exposed by each build system plugin.
* @BUILDSYSTEMS variable contains all buildsystems known to the manager in the
order of specialization.
-----------------------------
Contains a few classes which define a common interface for buildsystem plugins
and implements handling of common features (i.e. two types of the build
directory support, see below). Each specific build system plugin is supposed to
inherit from any of these base classes or from another build system plugin.
Currently implemented classes (packages) inside this .pm are:
-- Dh_Buildsystem_Basic --
a basic class describing buildsystem plugin API. It stores build directory
internally (can be retrieved with ::get_builddir() or path constructed using
::get_buildpath() (useful in is_buildable())) but does nothing with it. This
class is intended to be inherited by the build system plugins which do not
support outside-source tree building or there is no way to control this option
(as far as tell, Build.PL is like this). It also describes common buildsystem
plugin API and lays down the basic architecture:
* ::configure/::build/::test/::install/::clean methods - they will be called to
perform a respective action. These are wrapper methods by default and provide
a place to implement common features specific the action itself (like
creating build directory, see Dh_Buildsystem_Chdir::configure()) before
calling real buildsystem specific implementation. Default implementations
call the respective *_impl() method via another invoke_impl() wrapper.
* ::configure_impl/::build_impl/::test_impl/::install_impl/::clean-impl methods
- placeholders for the buildsystem specific implementation of the action (by
overriding the methods as needed). Default implementations do nothing.
* ::invoke_impl($method_name, @args) - a convenient way to hook in the code
which needs to be run before or after respective ::*_impl() of *each* action
(e.g. a simple case like setting envvar, see perl_build.pm). Default
implementation calls $self->$method_name(@args) by default.
So we have such a chain by default (and each can be overriden by any derived
class):
$self->$action() calls:
$self->invoke_impl("${action}_impl", @_) calls:
$self->$action_impl(@_) <- does buildsystem specific stuff here;
-- Dh_Buildsystem_Option --
extends Dh_Buildsystem_Basic and adds support for passing build directory name
via command line option to the build script (specific plugins should override
::get_builddir_option() method). ::invoke_impl() is overriden to pass value of
$self->get_builddir_option() to each ::$action_impl() method (python distutils
use such a way to set "build place", i.e. --build-place=builddir, see
python_distutils.pm).
-- Dh_Buildsystem_Chdir --
extends Dh_Buildsystem_Option. This class implements support for outside source
building when you need to chdir to the building directory before building (like e.g.
makefile.pm and its derivatives: autotools.pm and cmake.pm). All the code in there
deals with chdir'ing/mkdir'ing to the build directory as needed before calling
::$action_impl() and finally going back. This is done by overriding ::invoke_impl()
method.
-----------------------------
-----------------------------
And finally we have build system specific plugins as Debian/Debhelper/Buildsystem/*.pm.
Currently I have implemented 100% functionality of the former dh_auto_* tools
inside these plugins + cmake support in the cmake.pm:
$ ./dh_auto_configure -l
autotools - support for building GNU Autotools based packages.
cmake - support for building CMake based packages (outside-source tree only).
perl_build - support for building Perl Build.PL based packages (in-source only).
perl_makefile - support for building Perl Makefile.PL based packages (in-source only).
python_distutils - support for building Python distutils based packages.
makefile - support for building Makefile based packages (make && make install).
Current plugin inheritance hierarchy is like this:
Buildsystem::perl_build -> Dh_Buildsystem_Basic <- Buildsystem::perl_makefile
^ (maybe it should derive from ::perl_build?)
|
Buildsystem::python_distutils -> Dh_Buildsystem_Option
^
|
Dh_Buildsystem_Chdir
^
|
Buildsystem::makefile
^ ^

This is based on some work by Modestas Vainius, somewhat simplified
by a trick using excludes.
Note that the error in the case where there are no packages to build was
changed to a warning. That can easily happen now, and doesn't seem
particilarly error-worthy anyway; just exiting w/o doing anything seems
fine in that case.

I think I didn't do this before because it could result in
parseoptions() erroring because there were no packages to act on.
That is not going to be an error soon though, and it makes sense to
pass in the -N excludes.
