They implement a space efficent write-once database with fast access
path. Switch the services(5) database to use cdb. The size of the
database file decreases from 2.1MB disk space to 307KB. Access
performance is about the same if setservent(0) is used and about an
order of magnitude faster otherwise. services_mkdb defaults to the new
format, but can optionally create the old db(3) format as well for
statically linked legacy applications.
but it is specified by IEEE Std 1003.1, 2004 Edition (POSIX) and
the X/Open standards (Issue 6 and XNS 5.2).
* revert change removing gethostent() from gethostbyname(3) man page
* delete kruft from gethnamaddr.c leaving only gethostent() as a
wrapper around _gethtent().
* revert recent changes to <netdb.h>
+ restore gethostent() prototype
+ restore freehostent() prototype; handle similar to non-shipped
getipnodby*() prototypes
+ use correct XOPEN_SOURCE version (520 not 500) for freeaddrinfo()
prototype; interface specified by XNS5.2 not XNS5
Reviewd by <christos> and <drochner>.
In XNS5, and subsequently in POSIX-2001 it was changed to socklen_t.
To accomodate for this while preserving binary compatibility with the
old interface, prepend or append 32 bits of padding, depending on
the (LP64 data model) architecture's endianness. Fixes PR
standards/21411 from Ben Harris.
This should be deleted the next time the libc major number is
incremented.
Also, update getnetbyaddr(3)'s `net' argument accordingly.
* IPv6 functions are in POSIX-2001, so make them visible there.
* freehostent(), getipnodebyaddr() and getipnodebyname() are _only_ in
XNS5.2, so don't expose them to XSH6 or POSIX applications.
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.
int); this is consistent with RFC2553, the current draft-ietf-ipngwg-
rfc2553bis-05 and the majority of deployed implementations.
Also, there is an effort under way to have this changed back to int in
XBD6/XSH6, XNS, and POSIX-2001 TC1.
In XNS5.2, and subsequently in POSIX-2001 and draft-ietf-ipngwg-rfc2553bis-02
it was changed to a socklen_t.
