451: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 452: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
453: the instruction before the syscall to be a load immediate)

1.332 olaf 484: signal is now a correct signal (Olaf)
1.333 fefe 485: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
486: the built-in defaults.

1.450 leitner 524: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 525: upcoming AMD Hammer chips!). You can't even buy the chips yet and
526: the diet libc already supports it! Amazing ;-)
527: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 528: Andre sent a patch to add ARM profiling. He says it does not work

664: add fdatasync (and make it a pthread cancellation point)
665: numerous alpha issues, like using .quad instead of .long for
666: offsets, change strip to -strip in Makefile (so a failing strip does
667: not abort the make), try to be more friendly to the gcc 2.96 that
668: SuSE 7.1 AXP ships with.
1.224 fefe 669:
1.209 fefe 670: 0.14:
1.224 fefe 671: fix brk again (missing __brk, trivial oversight)
1.210 fefe 672: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
673: Thomas Ogrisegg!
1.211 fefe 674: Thomas also contributed a PA-RISC port including testandset, so
675: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 676: made the fake locale more believable.
677: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 678: moved _exit into the unified syscall on x86.
1.214 fefe 679: Uwe Ohse found many more bugs:
680: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
681: liblatin1 was more or less completely broken if you gave it chars as
682: arguments, not ints (signedness). execvp had a buffer overflow in
683: case a PATH element exceeded PATH_MAX, but it's not a security
684: problem since setuid programs need to set their path to some known
685: value anyway.
1.219 fefe 686: hasmntopt did not work with foo=bar style options
1.217 fefe 687: Uwe also improved ftw's stack usage.
1.214 fefe 688: Put movl instead of popl rationale in comment in i386/unified.S since
689: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 690: I discovered __attribute__((malloc)) and started using it. For gcc 3,
691: it improves the optimizer when functions return malloced pointers.
1.216 fefe 692: Steven Rostedt pointed out that my setvbuf was broken with regard to
693: size==0 and sent a patch to fix it.
1.218 fefe 694: Thomas Ogrisegg made setenv smaller.
1.220 olaf 695: Olaf: implemented the parisc clone and an atomic testandset, modified the
696: libpthread to respect the parisc UPgrowing stack. still non functional,
697: because the unified syscall uses errno :(
1.221 fefe 698: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 699: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
700: don't write anything which was no longer the case. It also
701: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 702: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 703:
1.193 fefe 704: 0.13:
1.194 fefe 705: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 706: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 707: Olaf: port to S/390!
1.463 leitner 708: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 709: res_query did not initialize last
1.199 fefe 710: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 711: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 712: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 713: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 714: rewrote __dtostr (it also has one more argument now)
1.205 fefe 715: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 716: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
717: fix strncat for the case where n == 0 (security implications?)
718: fix bsearch (it didn't find the very last element in the array, same
719: bug in both the C and the i386 assembly version).
1.205 fefe 720: fixed FNM_PATHNAME in fnmatch
1.204 fefe 721: fix brk (the syscall was documented incorrectly in the Linux man page)
722: Thanks, Thomas Ogrisegg!
1.205 fefe 723: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 724: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 725: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 726:
1.164 fefe 727: 0.12:
728: more contributions from Frank Klemm.
1.165 fefe 729: iconv can now do UCS-2, too.
1.167 fefe 730: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 731: Lots of bug fixes, and several more i386 specific versions of common
732: routines to make them smaller.
1.168 fefe 733: add memmem (a GNU extension that looks useful)
1.170 fefe 734: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 735: add pivot_root syscall, %n for *scanf.
1.169 fefe 736: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 737: add Frank Klemm's optimized md5
1.172 fefe 738: add -Os option to diet (see diet.1).
1.173 fefe 739: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 740: add 32-bit uid/gid syscalls.
1.175 fefe 741: add rand48 (thanks, Johannes Kloos)
1.176 fefe 742: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 743: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
744: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
745: fix gethostent alias list termination. Major oops.
1.178 fefe 746: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 747: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 748: DNS will now properly signal errors and set h_errno.
749: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 750: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
751: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
752: external reference to a symbol that is only in the diet libc. So,
753: when you accidentally link a diet libc compiled object file against
754: glibc, the linker will barf. This will bloat your object files, but
755: you can remove all the references with "strip -R .note" from
756: the binaries in the end (which you should do anyway).
1.182 fefe 757: fix ARM unified syscall (select did not work).
1.183 fefe 758: add getpwent_r ala glibc and replace getpwent
759: do the same for getgrent and getspent
760: remove entlib (new code is smaller)
1.184 fefe 761: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 762: add getpwnam_r and getpwuid_r
1.186 fefe 763: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 764: Olaf muddled with the dynamic linker. It's a clean-room
765: implementation in the sense that it once worked for Olaf in a clean
766: room ;)
1.188 fefe 767: add if_nameindex and if_freenameindex.
768: fixed arm unified syscalls to work with current binutils (; is no
769: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 770: changed all st_[cma]time types to signed long so comparisons against
771: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 772: fixed two bugs regarding ungetc.
773: add getusershell, setusershell, endusershell (for vs_ftpd)
774: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 775: fixed strftime (was completely hosed)
1.192 fefe 776: added real make install target
1.164 fefe 777:
1.115 fefe 778: 0.11:
779: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 780: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 781: add floor, ceil and memchr prototypes.
782: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 783: cleaner errno vs __errno_location handling
784: add placeholder iconv (iconv_open will always return EINVAL)
785: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
786: initialization of getaddrinfo.
1.119 fefe 787: fix vsnprintf %X (printed lower case)
1.120 fefe 788: I wrote a new getopt. It appears to actually work (it is POSIX
789: compliant, it does not sort argv like the GNU version) and is only
790: a little over 300 bytes on x86.
1.121 fefe 791: Guillaume Cottenceau just wrote me that strncat should be even more
792: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 793: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 794: Fix regexec offset return. autoconf now believes that diet libc has
795: POSIX regular expressions.
1.123 fefe 796: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 797: Fix regular expression match for x* when there is no x at all.
1.125 fefe 798: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 799: Add %h to vsnprintf.
1.127 fefe 800: Add FAQ.
1.128 fefe 801: Make %h work for signed numbers and add %hh to vsnprintf.
802: initgroups ignored the group argument :-(
803: remove printf references and nested functions from glob.
1.129 fefe 804: added an errno in libpthread that will display a prominent linker
805: warning.
1.131 fefe 806: started getting rid of kernel headers. Big task! :-(
1.130 fefe 807: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 808: Olaf: added a lot of code in libdl (not yet complete), changed the
809: startup code to make it work with his libdl and ld.so (needs still work
810: too)
1.134 fefe 811: __dns_readstartfiles only took the first domain or search path.
812: Thanks, Anthony de Boer
1.133 olaf 813: Olaf: added clone and a new unified_syscall for PowerPC
814: also dynlinker is now available (i386 only at this time)
1.135 fefe 815: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 816: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 817: fixed word delimiters in regex (they looked for space, i.e. "," did
818: not work as delimiter)
1.138 fefe 819: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 820: added mkdtemp.
1.142 fefe 821: Uwe Ohse reported all of the following bugs:
822: ttyname should return 0 if !isatty.
823: realpath returns NULL if "." cannot be opened
824: putenv erroneously accepted (and mishandled) entries without "=".
825: popen returned 255 instead of 127 if /bin/sh could not be run.
826: fgetc did not set the internal EOF indicator on EOF.
827: bsearch contained an assumption about integer arithmetic overflow
828: behavior.
829: system did not set SIGCHLD and thus contained a race.
830: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 831: daemon did not check whether open returns an fd below 3
832: perror did not save errno.
1.144 olaf 833: Olaf: Peter Jones reported some problems with perror; strerror had the
834: same problem.
835: Peter also posted a patch to atexit/exit. With some modifications it is
836: now implemented.
1.145 fefe 837: Unbuffered stdio and ungetc can no longer be disabled. I will try to
838: implement part of it using ELF weak symbols.
1.146 fefe 839: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 840: Added overflow handling for strtoul and strtol.
1.149 fefe 841: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
842: it before falling back to DNS if enabled.
1.150 fefe 843: Added a littie backwards compatibility cruft for gpm (man, do these
844: sources stink!)
1.151 fefe 845: Added openpty.
1.152 fefe 846: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 847: Fix fseek return value.
1.155 fefe 848: Add dirname and basename.
1.156 fefe 849: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 850: Fixed getservent (did not allow _ and - in the aliases).
851: Thanks, Oden Eriksson
1.158 fefe 852: Added a float.h so configure believes we have ANSI header files.
853: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 854: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 855: scanf and printf function implementations
1.160 fefe 856: Imported a few more functions and optimizations from Frank Klemm (he
857: also rewrote dtostr to have more precision)
1.161 olaf 858: Olaf: checked in a new sig* function family (based on rt_sig*).
859: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 860: Made rudimentary iconv that can convert back and forth between
861: iso-8859-1, utf-8 and ucs-4 (for debugging).
862: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 863:
1.74 fefe 864: 0.10:
865: update getpagesize.
866: add personality.
1.75 fefe 867: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 868: add putchar (apparently arm-linux-gcc will substitute printf("\n")
869: with putchar('\n') behind your back...?!
1.77 fefe 870: import include/scsi/ from glibc.
1.78 fefe 871: add iopl.
1.80 fefe 872: add execl and sigdelset prototypes.
873: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 874: add RPC headers (no code yet).
1.82 fefe 875: add mlockall, munlockall
1.83 fefe 876: make "diet gcc foo.c" work.
877: added Sun RPC code and removed as many warnings as possible in a
878: heroic act of self-mutilation.
879: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 880: added getpass. mount from util-linux actually compiles now!
881: fix the sig*set routines. mount actually works now *bg*
882: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 883: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 884: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 885: add res_init.
886: add asprintf (ugh, what an ugly function).
1.89 fefe 887: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 888: add ut_name alias to ut_host in struct utmp.
889: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 890: add sysinfo, recvmsg, sendmsg.
1.93 fefe 891: add endmntent, getmntent, setmntent.
1.94 fefe 892: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 893: add setenv.
894: remove __restrict from mntent.h, add __restrict__ removal alias for
895: older gcc versions in sys/cdefs.h.
896: add rlim_t, sig_atomic_t declarations.
897: add sigsetjmp #define for __sigsetjmp (oops).
898: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 899: add a gruesome hack to printf floating point to accept %f and kludge
900: together support for %.2f. Don't look at the code, please!
1.98 fefe 901: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 902: imported fix for entlib by Jeff Garzik.
1.100 fefe 903: add glob implementation from Guillaume Cottenceau (Thanks!!)
904: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 905: add REG_ICASE and word start/end handling to my regular expressions.
906: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 907: wrap getcwd to comply to man page (the syscall returns the number of
908: bytes, not the buffer)
909: add realpath.
1.103 fefe 910: fix vfprintf.
1.104 fefe 911: fix *scanf %s zero termination.
912: add abs, labs, llabs.
1.105 fefe 913: add <sys/io.h>, ioperm syscall.
914: add flock to <sys/file.h>
1.106 fefe 915: fixes to bsearch and the regular expressions.
1.107 fefe 916: add fake herror.
1.108 fefe 917: add scandir and alphasort.
1.109 fefe 918: add killpg
1.110 fefe 919: implemented a gross hack to make libpthread compile when
920: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 921: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 922: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 923: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
924: for sending a patch.
1.114 fefe 925: add getserv*.
926: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
927: "search" from resolv.conf.
1.74 fefe 928:
1.73 fefe 929: 0.9:
1.65 fefe 930: fixed initgroups (oops)
1.66 fefe 931: Cleanup appending file open for stdio (thanks, James Antill)
932: imported vfprintf fix from James Antill.
1.67 fefe 933: add fnmatch
934: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 935: Olaf added character classes to *scanf.
1.69 fefe 936: Put object and library files into a separate directory (bin-$ARCH).
937: Add "cross" make target to make all architectures.
938: Add "diet" program and man page.
1.70 fefe 939: Add getgrnam, getgrgid
1.71 fefe 940: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 941: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 942:
1.64 fefe 943: 0.8:
1.34 fefe 944: vsnprintf(0,...) estimated the length of strings with a padding width
945: incorrectly.
1.35 fefe 946: new reboot() from Olaf.
1.36 fefe 947: added prototypes for getsockopt and setsockopt.
1.39 fefe 948: added experimental sem* and shm*
1.38 fefe 949: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 950: added setvbuf (only changes mode, not buffer)
1.41 fefe 951: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
952: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 953: added qsort() and bsearch(). Benchmark on 1000 random ints:
954: glibc: 679414 cycles qsort and 3352 cycles bsearch
955: diet libc: 300010 cycles qsort, 553 cycles bsearch
956: I have no idea why glibc is so slow.
1.43 fefe 957: added __isnan (references by libm.a from glibc).
958: added popen() and pclose(). Now the diet libc can link slsh (from
959: S-Lang!)
1.44 fefe 960: corrected usleep. It was more of an msleep until now.
1.45 fefe 961: corrected __dtostr (it looped when trying to format "0.0").
962: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 963: added ungetc (does it work?)
1.47 fefe 964: added inet_aton (yuck!)
1.50 fefe 965: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 966: added h_errno and __h_errno_location
967: added inet_ntoa
1.49 fefe 968: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 969: add bcopy, index, rindex macros
970: add isgraph and isxdigit
1.52 fefe 971: add strftime (ugh!!!)
1.53 olaf 972: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 973: Jeff Garzik contributed a spec file. I put it in contrib and hope
974: everbody knows what to do with it...
975: Olaf checked in a ton of libpthread stuff.
1.55 fefe 976: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 977: add large file backwards compatibility support (so gzip will run on
978: kernel 2.2 and 2.0)
1.57 fefe 979: added shutdown
1.58 fefe 980: added nice
981: added pseudo-locale support for is* (they are now weak aliases,
982: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
983: overwrite the default is* functions.
1.59 fefe 984: added liblatin1.a
1.60 fefe 985: added tzfile implementation (does it work for anyone else?)
1.61 fefe 986: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 987: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
988: Thanks!
1.63 fefe 989: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 990:
1.21 fefe 991: 0.7.2:
992: added several prototypes to already implemented functions and
993: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 994: added prototypes for process group and dup syscalls. Thanks to
995: Abraham again. He also contributed an implementation for daemon(),
996: an ugly BSD hack. I decided to diversify the lib/ directory a
997: little and now created a libugly/ directory for stuff like system()
998: and daemon() ;-)
999: added libstdio and moved all that stdio crap from lib/ there. The
1000: idea is to start separating now what we will separate for shared
1001: libraries anyway.
1.26 fefe 1002: optimized x86 unified-syscall by Olaf.
1.27 fefe 1003: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
1004: limits.h instead)
1005: added remove.c and enough cruft to limits.h to make it compile lzo,
1006: lzop and bzip2.
1.28 fefe 1007: added mktime, asctime_r, asctime and ctime (needed for gzip).
1008: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 1009: format some day (man tzfile, ugh!) :-(
1.29 fefe 1010: added unlink prototype to unistd.h.
1011: added gmtime and gmtime_r.
1.31 fefe 1012: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 1013: removed readdir glibc compatibility cruft.
1.31 fefe 1014: removed stat glibc compatibility cruft.
1.32 fefe 1015: oops, my fread was broken for pipes.
1.33 fefe 1016: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1017:
1.9 fefe 1018: 0.7.1:
1.11 fefe 1019: optimized away the static arrays from __ltostr and __lltostr.
1020: optimized away the static arrays (and more!) from strtoul and strtoull.
1021: added system (by Olaf).
1.12 fefe 1022: added tolower and toupper
1.13 fefe 1023: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1024: added clone for mips (by Olaf).
1025: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1026: added pause for all (by Olaf).
1.17 fefe 1027: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1028: added isupper and islower.
1029: added putc and putchar as macros.
1.17 fefe 1030: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1031: insightful discussions and patches I partially used for the last three)
1.18 fefe 1032: added getpriority and setpriority (also by Abraham)
1.19 fefe 1033: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1034: oi, setjmp and longjmp were broken on other platforms, too!
1035: Thanks to Sébastien Côté for reporting this.
1.9 fefe 1036:
1037: 0.7:
1.6 olaf 1038: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1039: Initial dynamic loading glue for i386, also by Olaf.
1040: We don't have a dynamic loader yet, so this is not yet usable.
1041: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1042: vsprintf, writev, all by Olaf.
1.2 fefe 1043: imported readdir fix from Guillaume. Mhh, can the kernel interface
1044: really be this broken?
1.3 fefe 1045: Found a kludgy way to detect whether the kernel includes define struct
1046: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1047: not work for you, please tell me!
1.4 fefe 1048: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1049: Fixed stdio line buffering. The code was already there but I forgot
1050: to mark stdio and stdout as line buffered. This should really be
1051: done dynamically using isatty, though.
1.8 fefe 1052: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1053:
1054: 0.6.14:
1055: *scanf did not append the 0 byte for %s.
1056: added creat and changed creat to call open directly instead of open64.
1057: did for fread what 0.6.10 did for fwrite.
1058: repaired buffered stdio a little (line buffering is still not
1059: supported).
1060: [All of these bugs have been reported by Guillaume. Thanks!]
1061: added __pure__ to strchr and strrchr in <string.h>
1062:
1063: 0.6.13:
1064: included COPYING to make clear that the diet libc is covered by the
1065: GNU General Public License (and _not_ the LGPL). That means that
1066: you need to obtain a license from me if you want to use the diet
1067: libc in a proprietary program that you want to distribute.
1068: The x86 unified syscall swapped arguments #4 and #5 and noone
1069: noticed until now! Thanks to Guillaume Cottenceau for reporting
1070: this!
1071: The malloc had a subtle bug with small allocations that could cause
1072: segfault. Guillaume reported it, Olaf fixed it.
1073:
1074: 0.6.12:
1075: added assert, statfs and fstatfs
1076: added include/net/if.h so fget compiles again.
1077:
1078: 0.6.11:
1079: added putenv.
1080:
1081: 0.6.10:
1082: fixed fwrite. It returned the number of bytes written, not the number
1083: of records. Thanks to Albert D. Cahalan for pointing this out.
1084: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1085: added brk and sbrk. harold@nb.com.sg made me do it.
1086:
1087: 0.6.9:
1088: fixed execvp not to return on ENOENT
1089: did for {open|read|close|seek|tell}dir what I did for stat before.
1090: The glibc compatibility part is currently non-functional.
1091: fixed white space handling in sscanf " (" would not match " (".
1092: fixed printf to accept 'l' flag.
1093: fixed getpwuid (ignored last line)
1094:
1095: 0.6.8:
1096: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1097: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1098: added strlcpy and strlcat from OpenBSD.
1099: added stat64, fstat64 and lstat64.
1100: added endian.h and made ending of strlen.c endianness-aware
1101: added string routines size tweak to dietfeatures.h. Most of the
1102: string routines have been unrolled. This is up to three times as
1103: fast but creates up to three times larger code. Now you can disable
1104: the unrolling.
1105: added sendfile.
1106: I also added pread. It works on x86 and sparc but not on ppc and mips.
1107: I have no idea what's going on. strace disagrees with the kernel.
1108: Can anyone help? I asked the Linux kernel mailing list for help, too.
1109: added a few aliases of the type __libc_open for open. nm on
1110: libpthreads.so indicates that we will need them.
1111:
1112: 0.6.7:
1113: the sources now compile without warnings with -Wall.
1114: printf now prints "(null)" when %s is passed NULL. This can be
1115: removed with WANT_NULL_PRINTF in dietfeatures.h
1116: added vfprintf, execl, ttyname.
1117: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1118: __dietfstat so they can use the normal kernel struct stat.
1119: stat, lstat and fstat are now C wrappers that convert to the glibc
1120: struct stat. So we can avoid that overhead for programs that use
1121: dietlibc headers.
1122:
1123: 0.6.6:
1124: changed the Makefiles so you can now set CFLAGS on the command line
1125: added memccmp (analogous to memccpy) and strncmp.
1126: Olaf fixed another bug in the sparc unified syscall.
1127: Paul Clifford contributed a C version of his strlen.S that is much
1128: more efficient than the previous strlen on all platforms! It also
1129: looks like technology from Roswell. ;-}
1130: added a "real" stdio. Well, almost. Please contribute!
1131: added dietfeatures.h so you can remove features you don't need.
1132: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1133: stdio now works with simple programs and minigzip from libz.
1134: stdio uses some major trickery to avoid linking the stdio, stderr and
1135: stdout (and reserving space for them) when they are not used.
1136:
1137: 0.6.5:
1138: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1139: most of them bugs in the new header files, but also missing sigset
1140: functions.
1141: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1142: several bugs.
1143: Fixed ppc/setjmp and mips/pipe.
1144: Olaf contributed a new sparc unified syscall.
1145:
1146: 0.6.4:
1147: declared is* static inline in getservent.
1148: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1149: changed strlen to return 0 when passed NULL.
1150: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1151: Scientist who actually implemented this without access to a MIPS
1152: box, just from reading the architecture manual. And it worked out
1153: of the box.
1154: started a set of system includes, mainly so that I can use lcc and
1155: my alpha-linux cross compiler (which is unable to cross-compile
1156: glibc). diet libc can now be compiled without any include files
1157: from a normal libc. The includes do declare more than diet libc
1158: currently delivers and they are still far from complete for real
1159: applications.
1160: I will only add assembly versions that are smaller _and_ faster than
1161: the C version. Larger routines are only accepted if they are called
1162: very often and are substantially faster.
1163: added i386 assembly strchr, which is smaller and faster than the old
1164: version. It is, however, larger than the version contributed by
1165: proton (thanks, anyway).
1166: added i386 strlen (31% faster, 14% smaller)
1167: "make t" will now create a map file called "mapfile".
1168:
1169: 0.6.3:
1170: added sys_errlist, strerror and perror
1171: added isblank
1172: added atol
1173:
1174: 0.6.2:
1175: mmap for ARM didn't compile. Thanks, Paul!
1176:
1177: 0.6.1:
1178: split mmap into the architecture specific subdirectories.
1179: getenv now copes with environ==NULL, thanks Paul Clifford.
1180: Paul also contributed a smaller ARM startup code.
1181:
1182: 0.6:
1183: strcat returned the wrong result. Thanks, Dietz Pröpper.
1184: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1185: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1186: __dtostr does not work (I have no idea why!)
1187: The MIPS port now uses (much smaller) non-PIC code. That means that
1188: the applications you link against diet libc also have to be compiled
1189: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1190: Thanks to Ralf Bächle for helping me with this!
1191: I made subdirectories for the architectures and use VPATH to override
1192: VPATH so that make finds the source file automatically. That should
1193: simplify the sources greatly.
1194: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1195: ARM and MIPS now also have setjmp and longjmp
1196: "compile" and "load" are now make targets. Use them for djb programs.
1197: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1198: Again, contributed from Olaf. Great work!
1199:
1200: 0.5.12:
1201: printf also does signed numbers.
1202: If you don't use atexit, dietlibc now does not link exit, only _exit.
1203: *printf now correctly returns the number of bytes written.
1204: Olaf contributed experimental sscanf and vsscanf implementations.
1205: If passed NULL as buffer, snprintf will not write anything but still
1206: return the number of bytes it would have written.
1207: Initial MIPS port! (Oh, the agony!)
1208: No setjmp and longjmp support yet! Please contribute!
1209: I even implemented unified syscalls for MIPS. Still, MIPS code is
1210: almost twice the size of SPARC code. If anyone knows why: please
1211: tell me!
1212:
1213: 0.5.11:
1214: I implemented new unified syscalls for x86, sparc and ppc, this time based
1215: on .s files and not .c files, and I moved the syscalls into
1216: subdirectores to clean the dietlibc sources up a little.
1217: A binary consisting of printf("%s is %d\n","olaf",23) is now
1218: 2864 bytes on sparc
1219: 2488 bytes on intel
1220: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1221: to make a few more applications work.
1222: Olaf Dreesen also implemented some unified syscall stuff for x86.
1223: He discovered that with our unified syscall interface it actually
1224: costs <10 bytes total to make all system calls thread safe!
1225: I implemented atexit() (can register up to 4 callbacks).
1226: I implemented strtod and __dtostr (the opposite). Now we can add
1227: floating point support to vsnprintf and sscanf!
1228:
1229: 0.5.10:
1230: I actually saw that I can not only merge the errno handling code of
1231: the system calls on x86, I can also merge the rest (including the
1232: arguments) except for setting the system call number. All those
1233: system calls are now just a jump to a unified system call handler.
1234: I got rid of x86openclose again. The savings are substantial:
1235: chown from embutils went from 7664 to 7184 bytes!
1236: If I'd move the system call wrappers to assembly language, I could
1237: even reduce the alignment (does not matter since it's just a jump
1238: anyway) and get rid of the "ret" behind each jump (one byte per
1239: system call!)
1240:
1241: 0.5.9:
1242: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1243: fixed strdup
1244: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1245: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1246: (no signed integers, only strings and unsigned integers (but
1247: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1248: that code must be wonderful, I don't understand it at all *bg*)
1249: Olaf's printf does understand padding like in "%08d" and "%8d" and
1250: automatically pads pointers with '0'.
1251: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1252: Thanks to proton for inspiration on this.
1253: The new x86 start code also does not reference exit any more, thus saving
1254: 64 bytes for executables that don't call exit explicitly.
1255: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1256: Moved errno and environ to start.S, saving no byte binary size but
1257: speeding up compilation and slightly shortening dietlibc.a ;-)
1258: For x86: joined open and close into one assembler file, sharing the
1259: errno handling. This is a feasibility test and it actually saves a
1260: few bytes. I think I will reimplement the _syscall[1-6] macros on
1261: all platforms now to share the errno handling code for them.
1262:
1263: 0.5.8:
1264: fixed strchr to be able to look for 0.
1265:
1266: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1267: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1268: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1269: contributed by Olaf Dreesen)
1270:
1271: added execvp, getcwd
1272:
1273: fixed __xmknod
1274:
1275: Note: can it be that the ftw interface really is so broken that I
1276: cannot implement it without having to implement some searching data
1277: structure? I included an experimental ftw implementation that will
1278: not follow symlinks.
1279:
1280: 0.5.7:
1281: oops, if_nametoindex was broken!
1282:
1283: 0.5.6:
1284: ported to ppc-linux.
1285: fixed i386 sigsetjmp (I mistyped the function name)
1286: included sigjmp.c
1287:
1288: 0.5.5:
1289: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1290: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1291: I fixed it now.
1292: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1293: fixed readdir to use getdents and not the intel inline asm
1294:
1295: 0.5.4:
1296: ported to sparclinux (sparc32 only). Beware: does not work yet.
1297: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1298:
1299: 0.5.3:
1300: added tcsetattr and getenv to compile e3
1301:
1302: 0.5.2:
1303: added vhangup, tcgetattr, isatty and memcmp for fgetty
1304: (http://www.fefe.de/fgetty/)
1305: added localtime from uC-libc.
1306:
1307: 0.5.1:
1308: stat and friends actually work now. Yuck! Another case of
1309: translation between kernel and userland. Why can't the kernel
1310: people and the libc people simply agree on a standard?
1311: removed many unnecessary includes to speed up compilation.
1312: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1313: inlined socketcall to reduce code size.
1314: "load" and "compile" are examples for djb code.
1315:
1316: 0.5:
1317: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1318: each object file is now treated with "strip -x -R .note -R .comment"
1319: split each system call into a separate object file
1320: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1321:
1322: 0.4.1:
1323: oops, the strchr implementation was wrong. Thanks Jens Laas!
1324:
1325: 0.4:
1326: copied opendir and friends from uC-libc.
1327: added getservent and getservby* in gerservent.c
1328:
1329: 0.3:
1330: remove readdir system call
1331: added getdents system call
1332: added getpwnam/getpwuid implementation in getpwnam.c
1333: added a few string functions (in str*.c)
1334:
