--yrj/dFKFPuw6o+aM Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable A number of people have proposed a direction in 8.0 that would remove support for the syscalls and kernel data structures required by libkse. Apparently this would enable significant simplification of portions of the kernel, but I have no deeply held personal opinion. The intent is that if that happens, alternate versions of the necessicary dynamic libraries will be supplied in updated compat#x packages. This will address most consumers. The one set of consumers that would not be addressed is those who have statically linked, threaded binaries using libkse. Kris and I realized that if we went that route, life would be significantly easier if it was difficult to create statically linked, binaries using libkse under FreeBSD 7.x. As a result I would like to commit and MFC the following patch which disables building and installing libkse*.a in the default case. This would mean that significant effort would be required to create a statically linked application that uses the KSE syscalls. I believe that removing libkse*.a has little downside and leaves the way open for either removing or enhancing the KSE system and is the right thing to do. -- Brooks --- /home/brooks/working/freebsd/p4/freebsd/lib/libkse/Makefile 2007-10-29 = 10:43:55.000000000 -0500 +++ lib/libkse/Makefile 2007-11-20 20:39:22.000000000 -0600 @@ -10,12 +10,15 @@ =20 .include <bsd.own.mk> =20 -.if (${DEFAULT_THREAD_LIB} =3D=3D "libkse" || ${MK_LIBTHR} =3D=3D "no") &&= \ - ${SHLIBDIR} =3D=3D "/usr/lib" +.if (${DEFAULT_THREAD_LIB} =3D=3D "libkse" || ${MK_LIBTHR} =3D=3D "no") +LIB=3Dkse +.if ${SHLIBDIR} =3D=3D "/usr/lib" SHLIBDIR=3D /lib .endif +.else +SHLIB=3Dkse +.endif =20 -LIB=3Dkse SHLIB_MAJOR=3D 3 CFLAGS+=3D-DPTHREAD_KERNEL CFLAGS+=3D-I${.CURDIR}/../libc/include -I${.CURDIR}/thread \ --- /home/brooks/working/freebsd/p4/freebsd/ObsoleteFiles.inc 2007-11-18 04= :16:28.000000000 -0600 +++ ObsoleteFiles.inc 2007-11-20 20:37:39.000000000 -0600 @@ -14,6 +14,12 @@ # The file is partitioned: OLD_FILES first, then OLD_LIBS and OLD_DIRS las= t. # =20 +# 200711XX: Disabled installing static versions of libkse by default +.if ${DEFAULT_THREAD_LIB} !=3D "libkse" && ${MK_LIBTHR} !=3D "no" +OLD_FILES+=3Dusr/lib/libkse.a +OLD_FILES+=3Dusr/lib/libkse_p.a +OLD_FILES+=3Dusr/lib/libkse_pic.a +.endif # 20071108: Removed very crunch OLDCARD support file OLD_FILES+=3Detc/defaults/pccard.conf # 20071104: Removed bsdlabel, fdisk and gpt from rescue on ia64. --yrj/dFKFPuw6o+aM Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFHTdk9XY6L6fI4GtQRAp/kAKDUnMXL1A5WBpvjR67qFKco/OVy3wCfYEfy IJyQ8hDs72ADfzvPxIz3TGU= =qnCD -----END PGP SIGNATURE----- --yrj/dFKFPuw6o+aM--
