This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
New in 0.4.0:
* Real time timestamping support. (Dennis)
* Will unref plugins that don't match the ABI version. (Dennis)
* Added VisRectangle system. (Dennis)
* New BMP loader that supports all depths and RLE encoding. (Sepp)
* visual_mem_set(), visual_mem_set16(), visual_mem_set32()
Optimized memset functions. (Dennis)
* VisVideo new composite system. (Dennis)
* VisVideo sub regions. (Dennis)
* visual_video_zoom_*(). (Jaak)
* visual_video_mirror_*(). (Jaak)
* visual_video_rotate_*(). (Jaak)
* Removed obsolete visual_video_depth_transform_to_buffer(). (Jaak)
* Added VisCollection system. (Dennis)
* Added VisHashmap. (Dennis)
* Added VisCache. (Dennis)
* VisAudio rewrite. (Dennis)
* Added .license bit to VisPluginInfo for realtime license check. (Dennis)
* Removed .struct_size and .api_version from the VisPluginInfo structure,
and revamped the plugin version check system. Put
VISUAL_PLUGIN_API_VERSION_VALIDATOR somewhere in your plugin and it'll
work. (Dennis)
* Homedir installable plugins ~/.libvisual/actor transform morph input. (Dennis)
* Added VisOS. Realtime priority functions are hosted in this module. (Dennis)
* Added VisMath. All kind of math related functions have been added, most
note worthy are the _vectorized_. All of these are accelerated by
mmx/3dnow/sse instructions.
* VisFourier completely revamped. (Chong Kai Xiong)
Breaks compatibility with 0.2 releases.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
Libvisual is an abstraction library that comes between applications
and audio visualisation plugins.
Often when it comes to audio visualisation plugins or programs that
create visuals, they depend on a player or something else; basically,
there is no general framework that enabled application developers
to easily access cool audio visualisation plugins. Libvisual wants
to change this by providing an interface towards plugins and
applications; through this easy to use interface applications can
easily access plugins and, since the drawing is done by the
application, it also enables the developer to draw the visual
anywhere he wants.
The framework also allows you to morph to different plugins and
mix two at once; all kinds of neat tricks are possible using this
method.
