+INTRODUCTION +====================== +This directory contains a port of the Sun RPC code (derived +from the relicensed -- to 3-clause BSD -- implementation in +Fedora 11's libtirpc package version 0.1.10-7). It has been +adapted for newlib in the following ways: + +1) xdr_* functions for fixed-width integral types have been + added, such as xdr_int32_t() and similar. The implementation + of stream-specific x_putlong() and x_getlong() functions + has been modified to work properly whenever possible, even + if sizeof(long) > 32bits -- and to correctly report failure + when that is not possible. +2) Use of DEFUN(), EXFUN(), and various other portability + macros. +3) Uses of 64bit types, such as xdr_hyper, xdr_u_longlong_t, + and xdr_int64_t, as well as the xdr-specific typedefs + quad_t and u_quad_t, are guarded by ___int64_t_defined. +4) Out-of-memory conditions are indicated by returning FALSE + and setting errno = ENOMEM, rather than by printing error + messages to stderr. (See #8, below). +5) Only xdrstdio.c requires stdio support, and it is only + compiled if the target supports stdio (see stdio_dir in + configure.host) +6) Uses a local implementation of ntohl/htonl, rather than + one provided elsewhere. No dependency on any networking + functions. +7) Floating point support refactored. Currently supports + IEEE single and double precision, and VAX single and + double precision. + a) Those platforms which use float to represent double + do not provide xdr_double(). +8) Error reporting can be customized using a private hook. + This is described below. + +xdr is compiled and supported only for those platforms which +set xdr_dir nonempty in configure.host. At present, the list +of platforms which do this is: + cygwin + + +PORTING +====================== +To port XDR to a new newlib target, first enable building it +by modifying configure.host. Search for the 'case' statement +where various *_dir= variables are set, and look for your +target's entry (or add one if not present). Set xdr_dir: + + *-*-myplatform*) + xdr_dir=xdr + ;; + +If your platform does not use IEEE754 standard formats for +floating point values (floats, doubles) you may need to add +a new xdr_float_*.c implementation, and modify the bottom of +xdr_float.c: + + ... + #elif defined(__vax__) + #include "xdr_float_vax.c" + +#else defined(__my_platform__) + +#include "xdr_float_my_platform.c" + #endif + +You may want to customize your platform's startup objects to set +the error reporting callback for xdr (not likely, but see ERROR +MESSAGES section). + +You may also want to customize the memory allocation semantics +employed by the xdr routines. As stated in the xdr.h header: + + XDR_DECODE may allocate space if the pointer [to the location + at which the decoded data is to be stored] is NULL. This + data can be freed with the XDR_FREE operation. + +The default implementation defines the following macros in +rpc/types.h, used throughout xdr/ to deal with memory +allocation: + + #ifndef mem_alloc + #define mem_alloc(bsize) calloc(1, bsize) + #endif + #ifndef mem_free + #define mem_free(ptr, bsize) free(ptr) + #endif + +By arranging that these symbols are #defined to some other +memory allocation functions, different memory semantics can be +imposed. To disallow memory allocation entirely, use the +following: + + -D'mem_alloc(a)'=NULL -D'mem_free(a,b)'='do { ; } while(0)' + +In this case, any operations which would otherwise require +memory to be allocated, will instead fail (return FALSE), +and set errno=ENOMEM. + + +ERROR MESSAGES +====================== +This implementation of xdr provides a special hook, so that +error messages generated by xdr may be captured by a user- +defined facility. For certain error conditions, the internal +printf-like function + xdr_warnx (fmt, ...) +is called. However, that function simply delegates to an +internal function pointer to a callback function if set; +otherwise, xdr_warnx does nothing. + +By setting this function pointer to a user-defined callback, +the user can enable these messages to go to a syslog, stderr, +or some other facility. The function should match the +following typedef (see xdr_private.h): + + typedef void (* xdr_vprintf_t) (const char *, va_list); + +The desired callback can be registered by calling: + + xdr_vprintf_t xdr_set_vprintf (xdr_vprintf_t fnptr); + +The return value is the "old" function pointer, which may +be NULL. + +However, neither the typedef or the registration function +are declared in the public headers. Clients wishing to use +them must either declare the necessary symbols manually, +or #include "xdr_private.h". More on this point, below. + +For instance: + #include <stdarg.h> + #include <stdio.h> + typedef void (* xdr_vprintf_t) (const char *, va_list); + xdr_vprintf_t xdr_set_vprintf (xdr_vprintf_t fnptr); + + void my_vwarnx (const char * fmt, va_list ap) + { + (void) fprintf (stderr, fmt, ap); + } + + main() + { + (void) xdr_set_vprintf (&my_vwarnx); + ... + } + +Will cause xdr-generated error messages to go to stderr. + +It is not expected that end-user applications will make use +of this facility. Rather, it is expected that IF certain +*platforms* desire that these error messages be recorded, +rather expecting client apps print error messages as +necessary, then those platforms will, in their startup +objects or static initialization, direct these messages to +a logging facility, strace debug facility, etc. + +Therefore, the platform startup code, if part of newlib, can +#include "xdr_private.h", or simply copy the two declarations +from that file. + +However, most newlib targets will probably be satisfied with +the default (silent) behavior. Note that the original Sun RPC, +as well as the glibc implementation, print these error messages +to stderr. Cygwin, for greater similarity to glibc, registers +an error message handler similar to the example above, within +its startup code. + +(*) Client apps should already check for FALSE return values; + in this case they would then check errno and act appropriately. + + +LICENSING AND PEDIGREE +====================== +For years, the Sun RPC code, and the XDR implementation, was in +legal license limbo + http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=181493 +as its license terms, while open, were of debatable compatibility +with the GPL.
