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.

the Spectrum 128.

* Allow MDR images with bad checksums to load (the error will be handled by
the If1 ROM).

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).
around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
* Support for Scorpion ZS 256, Spectrum +3e, and Spectrum SE
* Support for .hdf hard disk images
* Support for the ZXATASP and ZXCF interfaces
* Support for saving the Timex DOCK and EXROM in .szx snapshots
* Support for saving the Interface II state
by moving the inclusion of buildlink3.mk files outside of the protected
region. This bug would be seen by users that have set PREFER_PKGSRC
or PREFER_NATIVE to non-default values.
BUILDLINK_PACKAGES should be ordered so that for any package in the
list, that package doesn't depend on any packages to the left of it
in the list. This ordering property is used to check for builtin
packages in the correct order. The problem was that including a
buildlink3.mk file for <pkg> correctly ensured that <pkg> was removed
from BUILDLINK_PACKAGES and appended to the end. However, since the
inclusion of any other buildlink3.mk files within that buildlink3.mk
was in a region that was protected against multiple inclusion, those
dependencies weren't also moved to the end of BUILDLINK_PACKAGES.
* Transparent reading of bzipped and gzipped files.
* Add support for writing emulator custom data to .rzx and .szx files.
* Update to the more recent version of gcrypt; version 1.1.42 or
later is now required.
* Link libspectrum against gcrypt, glib and zlib; this means that
client applications no longer need to do this.
* Support for 'the last instruction was an EI' in the snapshot code.
* Routines to check the versions of libspectrum and gcrypt in use.
* Write .rzx files with a version number of 0.12 if we're not
signing the data; improves backward compatability.
* Fix a segfault when dealing with .slt files.
* QNX6 compilation fixes.
ZX Spectrum emulator files slightly easier. It is intended to be usable
on Unix variants, Win32 and MacOSX.
Changes 0.2.0:
* libspectrum 0.2.0 released.
* Various data structures (snapshots, tapes, tape blocks) which
were previously directly accessible are now accessible only via
wrapper functions. This should improve future binary
compatability, but at the cost of breaking it for this release
(Philip Kendall).
* Change the API for reading/writing snapshots to be more general.
The old API still exists, but is deprecated (Philip Kendall).
* Support for reading .szx, .zxs, .sp, .snp and +D snapshots
(Philip Kendall).
* Support for writing .szx and .sna snapshots (Philip Kendall).
* Support for reading Warajevo .tap files (Fredrick Meunier).
* Support for signing RZX files with digital signatures (Philip
Kendall).
* Timing fixes for the TC2048 and TC2068 (Fredrick Meunier).
* Fix reading of 128K .sna snapshots (Philip Kendall).
* New capabilities for the Timex dock, and built-in Sinclair and
Kempston joysticks (Fredrick Meunier).
* Use <stdint.h> to give us the <n>-bit types if it's available
(Philip Kendall).
* Ignore links to external snapshots from RZX files, rather than
trying to interpret the path as a snapshot (Philip Kendall).
