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.
01/01/2007 *** v2.20 ***
- Added 'prune' feature for removing roms, disk and/or samples
- Added 'incorporate' feature to assist in combining datafiles
30/12/2006 *** v2.19 ***
- Internal change that only affects MAMEDiff (see note below)
- Improved -dX modes (understands merging despite differing names)
17/10/2006 *** v2.18 ***
- More intelligent DTD creation when saving in ListXML format
- Added support for game/display (MAME v0.107)
- Added support for game/input/control (MAME v0.107)
- Added support for emulator/build (MAME+MESS v0.101u4 upwards)
- Added support for driver/savestate (MAME v0.101u1 upwards)
- Note: The above changes affect the tab delimited format!
16/07/2006 *** v2.17 ***
- Fixed bug that caused the DatUtil -g and -r options to crash
11/07/2006 *** v2.16 ***
- Fixed bug that messed up internal indices (affected crc matching)
- More intelligent directory scanner (regarding samples and CHDs)
- Removed 64MB file limit from directory scanner (reads 1MB blocks)
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
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).
