From 11160cb76f56e0a711686e34881a4eaf1ad2fa0e Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Sun, 21 Aug 2016 15:38:41 -0400 Subject: Installed-header hygiene (BZ#20366): obsolete BSD u_* types. The types u_char, u_short, u_int, u_long, ushort, uint, ulong, u_int8_t, u_int16_t, u_int32_t, u_int64_t, quad_t, and u_quad_t are BSDisms that have never been standardized. While glibc should continue to *provide* these types for compatibility's sake, its public headers should not use them. The meat of this change was mechanically generated by the following shell command: perl -pi~ -e ' s/\b(__)?u_char\b/unsigned char/g; s/\b(__)?u_?short\b/unsigned short/g; s/\b(__)?u_?int\b/unsigned int/g; s/\b(__)?u_?long\b/unsigned long/g; s/\b(__)?u_int8_t\b/uint8_t/g; s/\b(__)?u_int16_t\b/uint16_t/g; s/\b(__)?u_int32_t\b/uint32_t/g; s/\b(__)?u_int64_t\b/uint64_t/g; s/\b(__)?u_quad_t\b/uint64_t/g; s/\b(__)?quad_t\b/uint64_t/g; ' $(grep -lE -e '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>' \ $(grep -LE '\<(_(SYS|BITS)_TYPES_H|rpc/(rpc|rpc_msg|types|xdr)\.h)\>' \ $(find . \( -false $(sed 's/^/-o -name /' all-installed-headers) \ \) -printf '%P\n' | sort -u))) where 'all-installed-headers' was a list of the basenames of all installed header files, manually extracted from the Makefiles. Non-installed wrapper headers in include/ are also adjusted, for consistency. I then manually fixed up indentation and line-wrapping. sys/types.h and bits/types.h are excluded because they must continue to define the u_* types (under __USE_MISC) for compatibility with applications. They do not use these types themselves. All headers that (transitively) include rpc/types.h are also excluded, for three reasons. First, the u_* types are defined by rpc/types.h, unconditionally (not just under __USE_MISC) so they are logically part of the SunRPC API. Second, many of those headers appear to be machine-generated. Third, it's my understanding that we are getting rid of as much of SunRPC as possible in the near future. (The one file under sunrpc/ that's touched, sunrpc/rpc/rpc_des.h, does *not* include rpc/types.h. This may itself be a bug.) After changing from u_intNN_t to uintNN_t, a number of headers now need to include stdint.h to pick up those types. It might be more hygenic, namespace-wise, to use __uintNN_t instead, but none of these headers are bound by ISO or POSIX to do so, and it's unlikely that anyone using them will be bothered. (The two files that were using __-prefixed versions of the u_types, sysdeps/mach/hurd/net/route.h and sysdeps/unix/sysv/linux/net/route.h, both already also contained uses of the unprefixed versions.) Some of these files directly included features.h and/or sys/cdefs.h, which I removed, as the style generally seems to be to let sys/types.h do that for us. (This does not change the set of definitions exposed by any header; sys/types.h unconditionally includes both features.h and sys/cdefs.h.) One file included asm/types.h unnecessarily. * bits/in.h, gmon/sys/gmon.h, inet/netinet/igmp.h * inet/protocols/routed.h, inet/protocols/talkd.h * inet/protocols/timed.h, io/fts.h, nptl_db/thread_db.h * resolv/arpa/nameser.h, resolv/resolv.h, sunrpc/rpc/rpc_des.h * sysdeps/generic/netinet/if_ether.h * sysdeps/generic/netinet/in_systm.h * sysdeps/generic/netinet/ip.h, sysdeps/generic/netinet/tcp.h * sysdeps/gnu/netinet/ip_icmp.h, sysdeps/gnu/netinet/tcp.h * sysdeps/gnu/netinet/udp.h, sysdeps/mach/hurd/net/ethernet.h * sysdeps/mach/hurd/net/if_arp.h * sysdeps/mach/hurd/net/if_ppp.h * sysdeps/mach/hurd/net/route.h, sysdeps/mach/sys/reboot.h * sysdeps/unix/sysv/linux/bits/in.h * sysdeps/unix/sysv/linux/net/ethernet.h * sysdeps/unix/sysv/linux/net/if_arp.h * sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_shaper.h * sysdeps/unix/sysv/linux/net/route.h * sysdeps/unix/sysv/linux/netinet/if_ether.h * sysdeps/unix/sysv/linux/netinet/if_fddi.h * sysdeps/unix/sysv/linux/netinet/if_tr.h * sysdeps/unix/sysv/linux/netipx/ipx.h * sysdeps/unix/sysv/linux/sys/acct.h * include/arpa/nameser.h, include/resolv.h: Change all uses of u_char to unsigned char, u_short and ushort to unsigned short, u_int and uint to unsigned int, u_long and ulong to unsigned long, u_int8_t to uint8_t, u_int16_t to uint16_t, u_int32_t to uint32_t, quad_t to int64_t, and u_int64_t and u_quad_t to uint64_t. * mach/sys/reboot.h: Remove two casts of integer literals to the types they already have. * bits/in.h: Correct error in description of IP_MULTICAST_LOOP. * sysdeps/unix/sysv/linux/bits/in.h: Likewise. * sysdeps/unix/sysv/linux/netinet/if_ether.h: Change a comment from referring to 'unsigned char' to 'uint8_t' for consistency with the macro definition below. * gmon/sys/gmon.h, inet/netinet/igmp.h, inet/protocols/talkd.h * io/fts.h, resolv/arpa/nameser.h, resolv/resolv.h * sunrpc/rpc/rpc_des.h, sysdeps/generic/netinet/ip.h * sysdeps/gnu/netinet/tcp.h, sysdeps/gnu/netinet/udp.h * sysdeps/mach/hurd/net/if_ppp.h, sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/sys/acct.h * include/arpa/nameser.h, include/resolv.h: Fix indentation disrupted by mechanical edits. * inet/protocols/talkd.h, resolv/arpa/nameser.h * sysdeps/generic/netinet/in_systm.h * sysdeps/gnu/netinet/ip_icmp.h, sysdeps/gnu/netinet/tcp.h * sysdeps/gnu/netinet/udp.h * sysdeps/unix/sysv/linux/net/ethernet.h * sysdeps/unix/sysv/linux/net/if_arp.h * sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_shaper.h * sysdeps/unix/sysv/linux/netinet/if_fddi.h * sysdeps/unix/sysv/linux/netinet/if_tr.h * sysdeps/unix/sysv/linux/netipx/ipx.h * sysdeps/unix/sysv/linux/sys/acct.h Include stdint.h for uintNN_t definitions.
