Subject: set major version of shlibs to 0
X-Git-Tag: v3.2.1~557
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/doc/syslog.3.html?a=commitdiff_plain;h=73379f0be5cea4faacaceb9ad90ebbf2c16096aa;p=minix.git

set major version of shlibs to 0

WARNING: this will break existing dynamically linked binaries if they
exist. If you have any:
	. re-build world statically first if necessary
	. remove libraries from /lib and /usr/lib
	. then build world

This change:
	. avoids possible future dismay when interfacing other
	  systems' binaries; done until they are abi-compatible

Thanks to Antoine Leca for pointing this out.

+	WARNING: the shared libraries major revision set to 0 will break
+	existing dynamically linked binaries if they exist.
+
+	There are two risks. One: existing binaries won't find the current
+	libraries; two: linking binaries with both majors present will link
+	them in twice. So the previous libraries have to be removed.

-# things we wish to do on next major version bump:
-# - libc/net/rcmd.c: make __ivaliduser() and __ivaliduser_sa() static
-# - libc/net: resolver update to BIND8/9?
-# - md2, md4, md5, rmd160 & sha1 functions should take the same arguments AFAP
-# - libc/gen/assert.c: __{diag,}assert13() -> __{diag,}assert()
-# - libc/gen/times.c: remove; __times13() -> times()
-# - libc/gen/timezone.c: remove; __timezone13 -> timezone
-# - libc/net/getaddrinfo.c, netdb.h: remove __ai_pad0
-# - libc/gen/utmpx.c, utmpx.h: remove lastlogxname, __getlastlogx13 -> getlastlogx
-# - infinity{,f,l}.c, math.h: __infinity -> __huge_val
-# - libc/gen/is{inf,nan}d_ieee754.c: remove is{inf,nan} aliases
-# - libc/arch/vax/gen/is{inf,nan}.c: remove
-# - libc/db/hash/ndbm.c: remove; __ndbm13 -> ndbm
-# - libc/net/getnet{ent,namadr}.c, netdb.h: remove __n_pad0
-# - libc/stdio: make _file an int, hide struct FILE, stdin, stdout, stderr impls
-# - libc/stdio: make fpos_t larger.  see BUGS section in fgetpos(3).
-#   probably s/fpos_t/off_t/ in __sFILE and __sseek().  it involves
-#   funopen(3) api change.
-# - remove frexp, ldexp, modf: they belong to libm.
-# - make sure we can support thread local [on arm don't use r9 for example,
-#   consider other risc architectures: mips, powerpc, sparc, etc]
-# - rename __libc_mutex_lock and similar back to pthread_mutex_lock.
-#   the functions are used by third party code without prototypes.
-#   for example in assembler code.
-# - kill sigcontext: never request version 0 or 1 signal trampoline.
-#   always request version 2 trampoline. (on vax, 3).
-# - change _ctype_ table in ctype.h and gen/ctype_.c 8bit -> 16 or 32bit.
-#   it's insufficient bitwidth to implement all ctype class.
-#   see isblank's comment in ctype.h.
