403: they put a #error in their source code. Is Erik seeing the diet
404: libc as uClibc competition that needs to be squashed even with
405: unfair methods? People, if you find bugs, tell us!
406: Fixed fputc and freopen (found in busybox comments)

435: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 436: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
437: the instruction before the syscall to be a load immediate)

1.332 olaf 468: signal is now a correct signal (Olaf)
1.333 fefe 469: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
470: the built-in defaults.

1.450 leitner 508: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 509: upcoming AMD Hammer chips!). You can't even buy the chips yet and
510: the diet libc already supports it! Amazing ;-)
511: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 512: Andre sent a patch to add ARM profiling. He says it does not work

610: pointer on little endian ARM and MIPS.
611: MIPS unified syscall didn't compile anymore.
612: Put up new mipsel target to cross compile for little endian mips.
613: The mips target will again explicitly set endianness to big endian.
614: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 615: Duh, when we removed return0, we broke tzset when the time zone parser
616: was disabled. Uwe Ohse noticed this. Thanks!

648: add fdatasync (and make it a pthread cancellation point)
649: numerous alpha issues, like using .quad instead of .long for
650: offsets, change strip to -strip in Makefile (so a failing strip does
651: not abort the make), try to be more friendly to the gcc 2.96 that
652: SuSE 7.1 AXP ships with.
1.224 fefe 653:
1.209 fefe 654: 0.14:
1.224 fefe 655: fix brk again (missing __brk, trivial oversight)
1.210 fefe 656: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
657: Thomas Ogrisegg!
1.211 fefe 658: Thomas also contributed a PA-RISC port including testandset, so
659: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 660: made the fake locale more believable.
661: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 662: moved _exit into the unified syscall on x86.
1.214 fefe 663: Uwe Ohse found many more bugs:
664: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
665: liblatin1 was more or less completely broken if you gave it chars as
666: arguments, not ints (signedness). execvp had a buffer overflow in
667: case a PATH element exceeded PATH_MAX, but it's not a security
668: problem since setuid programs need to set their path to some known
669: value anyway.
1.219 fefe 670: hasmntopt did not work with foo=bar style options
1.217 fefe 671: Uwe also improved ftw's stack usage.
1.214 fefe 672: Put movl instead of popl rationale in comment in i386/unified.S since
673: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 674: I discovered __attribute__((malloc)) and started using it. For gcc 3,
675: it improves the optimizer when functions return malloced pointers.
1.216 fefe 676: Steven Rostedt pointed out that my setvbuf was broken with regard to
677: size==0 and sent a patch to fix it.
1.218 fefe 678: Thomas Ogrisegg made setenv smaller.
1.220 olaf 679: Olaf: implemented the parisc clone and an atomic testandset, modified the
680: libpthread to respect the parisc UPgrowing stack. still non functional,
681: because the unified syscall uses errno :(
1.221 fefe 682: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 683: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
684: don't write anything which was no longer the case. It also
685: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 686: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 687:
1.193 fefe 688: 0.13:
1.194 fefe 689: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 690: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 691: Olaf: port to S/390!
1.463 leitner 692: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 693: res_query did not initialize last
1.199 fefe 694: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 695: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 696: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 697: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 698: rewrote __dtostr (it also has one more argument now)
1.205 fefe 699: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 700: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
701: fix strncat for the case where n == 0 (security implications?)
702: fix bsearch (it didn't find the very last element in the array, same
703: bug in both the C and the i386 assembly version).
1.205 fefe 704: fixed FNM_PATHNAME in fnmatch
1.204 fefe 705: fix brk (the syscall was documented incorrectly in the Linux man page)
706: Thanks, Thomas Ogrisegg!
1.205 fefe 707: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 708: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 709: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 710:
1.164 fefe 711: 0.12:
712: more contributions from Frank Klemm.
1.165 fefe 713: iconv can now do UCS-2, too.
1.167 fefe 714: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 715: Lots of bug fixes, and several more i386 specific versions of common
716: routines to make them smaller.
1.168 fefe 717: add memmem (a GNU extension that looks useful)
1.170 fefe 718: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 719: add pivot_root syscall, %n for *scanf.
1.169 fefe 720: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 721: add Frank Klemm's optimized md5
1.172 fefe 722: add -Os option to diet (see diet.1).
1.173 fefe 723: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 724: add 32-bit uid/gid syscalls.
1.175 fefe 725: add rand48 (thanks, Johannes Kloos)
1.176 fefe 726: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 727: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
728: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
729: fix gethostent alias list termination. Major oops.
1.178 fefe 730: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 731: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 732: DNS will now properly signal errors and set h_errno.
733: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 734: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
735: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
736: external reference to a symbol that is only in the diet libc. So,
737: when you accidentally link a diet libc compiled object file against
738: glibc, the linker will barf. This will bloat your object files, but
739: you can remove all the references with "strip -R .note" from
740: the binaries in the end (which you should do anyway).
1.182 fefe 741: fix ARM unified syscall (select did not work).
1.183 fefe 742: add getpwent_r ala glibc and replace getpwent
743: do the same for getgrent and getspent
744: remove entlib (new code is smaller)
1.184 fefe 745: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 746: add getpwnam_r and getpwuid_r
1.186 fefe 747: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 748: Olaf muddled with the dynamic linker. It's a clean-room
749: implementation in the sense that it once worked for Olaf in a clean
750: room ;)
1.188 fefe 751: add if_nameindex and if_freenameindex.
752: fixed arm unified syscalls to work with current binutils (; is no
753: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 754: changed all st_[cma]time types to signed long so comparisons against
755: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 756: fixed two bugs regarding ungetc.
757: add getusershell, setusershell, endusershell (for vs_ftpd)
758: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 759: fixed strftime (was completely hosed)
1.192 fefe 760: added real make install target
1.164 fefe 761:
1.115 fefe 762: 0.11:
763: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 764: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 765: add floor, ceil and memchr prototypes.
766: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 767: cleaner errno vs __errno_location handling
768: add placeholder iconv (iconv_open will always return EINVAL)
769: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
770: initialization of getaddrinfo.
1.119 fefe 771: fix vsnprintf %X (printed lower case)
1.120 fefe 772: I wrote a new getopt. It appears to actually work (it is POSIX
773: compliant, it does not sort argv like the GNU version) and is only
774: a little over 300 bytes on x86.
1.121 fefe 775: Guillaume Cottenceau just wrote me that strncat should be even more
776: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 777: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 778: Fix regexec offset return. autoconf now believes that diet libc has
779: POSIX regular expressions.
1.123 fefe 780: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 781: Fix regular expression match for x* when there is no x at all.
1.125 fefe 782: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 783: Add %h to vsnprintf.
1.127 fefe 784: Add FAQ.
1.128 fefe 785: Make %h work for signed numbers and add %hh to vsnprintf.
786: initgroups ignored the group argument :-(
787: remove printf references and nested functions from glob.
1.129 fefe 788: added an errno in libpthread that will display a prominent linker
789: warning.
1.131 fefe 790: started getting rid of kernel headers. Big task! :-(
1.130 fefe 791: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 792: Olaf: added a lot of code in libdl (not yet complete), changed the
793: startup code to make it work with his libdl and ld.so (needs still work
794: too)
1.134 fefe 795: __dns_readstartfiles only took the first domain or search path.
796: Thanks, Anthony de Boer
1.133 olaf 797: Olaf: added clone and a new unified_syscall for PowerPC
798: also dynlinker is now available (i386 only at this time)
1.135 fefe 799: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 800: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 801: fixed word delimiters in regex (they looked for space, i.e. "," did
802: not work as delimiter)
1.138 fefe 803: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 804: added mkdtemp.
1.142 fefe 805: Uwe Ohse reported all of the following bugs:
806: ttyname should return 0 if !isatty.
807: realpath returns NULL if "." cannot be opened
808: putenv erroneously accepted (and mishandled) entries without "=".
809: popen returned 255 instead of 127 if /bin/sh could not be run.
810: fgetc did not set the internal EOF indicator on EOF.
811: bsearch contained an assumption about integer arithmetic overflow
812: behavior.
813: system did not set SIGCHLD and thus contained a race.
814: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 815: daemon did not check whether open returns an fd below 3
816: perror did not save errno.
1.144 olaf 817: Olaf: Peter Jones reported some problems with perror; strerror had the
818: same problem.
819: Peter also posted a patch to atexit/exit. With some modifications it is
820: now implemented.
1.145 fefe 821: Unbuffered stdio and ungetc can no longer be disabled. I will try to
822: implement part of it using ELF weak symbols.
1.146 fefe 823: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 824: Added overflow handling for strtoul and strtol.
1.149 fefe 825: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
826: it before falling back to DNS if enabled.
1.150 fefe 827: Added a littie backwards compatibility cruft for gpm (man, do these
828: sources stink!)
1.151 fefe 829: Added openpty.
1.152 fefe 830: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 831: Fix fseek return value.
1.155 fefe 832: Add dirname and basename.
1.156 fefe 833: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 834: Fixed getservent (did not allow _ and - in the aliases).
835: Thanks, Oden Eriksson
1.158 fefe 836: Added a float.h so configure believes we have ANSI header files.
837: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 838: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 839: scanf and printf function implementations
1.160 fefe 840: Imported a few more functions and optimizations from Frank Klemm (he
841: also rewrote dtostr to have more precision)
1.161 olaf 842: Olaf: checked in a new sig* function family (based on rt_sig*).
843: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 844: Made rudimentary iconv that can convert back and forth between
845: iso-8859-1, utf-8 and ucs-4 (for debugging).
846: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 847:
1.74 fefe 848: 0.10:
849: update getpagesize.
850: add personality.
1.75 fefe 851: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 852: add putchar (apparently arm-linux-gcc will substitute printf("\n")
853: with putchar('\n') behind your back...?!
1.77 fefe 854: import include/scsi/ from glibc.
1.78 fefe 855: add iopl.
1.80 fefe 856: add execl and sigdelset prototypes.
857: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 858: add RPC headers (no code yet).
1.82 fefe 859: add mlockall, munlockall
1.83 fefe 860: make "diet gcc foo.c" work.
861: added Sun RPC code and removed as many warnings as possible in a
862: heroic act of self-mutilation.
863: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 864: added getpass. mount from util-linux actually compiles now!
865: fix the sig*set routines. mount actually works now *bg*
866: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 867: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 868: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 869: add res_init.
870: add asprintf (ugh, what an ugly function).
1.89 fefe 871: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 872: add ut_name alias to ut_host in struct utmp.
873: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 874: add sysinfo, recvmsg, sendmsg.
1.93 fefe 875: add endmntent, getmntent, setmntent.
1.94 fefe 876: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 877: add setenv.
878: remove __restrict from mntent.h, add __restrict__ removal alias for
879: older gcc versions in sys/cdefs.h.
880: add rlim_t, sig_atomic_t declarations.
881: add sigsetjmp #define for __sigsetjmp (oops).
882: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 883: add a gruesome hack to printf floating point to accept %f and kludge
884: together support for %.2f. Don't look at the code, please!
1.98 fefe 885: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 886: imported fix for entlib by Jeff Garzik.
1.100 fefe 887: add glob implementation from Guillaume Cottenceau (Thanks!!)
888: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 889: add REG_ICASE and word start/end handling to my regular expressions.
890: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 891: wrap getcwd to comply to man page (the syscall returns the number of
892: bytes, not the buffer)
893: add realpath.
1.103 fefe 894: fix vfprintf.
1.104 fefe 895: fix *scanf %s zero termination.
896: add abs, labs, llabs.
1.105 fefe 897: add <sys/io.h>, ioperm syscall.
898: add flock to <sys/file.h>
1.106 fefe 899: fixes to bsearch and the regular expressions.
1.107 fefe 900: add fake herror.
1.108 fefe 901: add scandir and alphasort.
1.109 fefe 902: add killpg
1.110 fefe 903: implemented a gross hack to make libpthread compile when
904: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 905: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 906: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 907: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
908: for sending a patch.
1.114 fefe 909: add getserv*.
910: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
911: "search" from resolv.conf.
1.74 fefe 912:
1.73 fefe 913: 0.9:
1.65 fefe 914: fixed initgroups (oops)
1.66 fefe 915: Cleanup appending file open for stdio (thanks, James Antill)
916: imported vfprintf fix from James Antill.
1.67 fefe 917: add fnmatch
918: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 919: Olaf added character classes to *scanf.
1.69 fefe 920: Put object and library files into a separate directory (bin-$ARCH).
921: Add "cross" make target to make all architectures.
922: Add "diet" program and man page.
1.70 fefe 923: Add getgrnam, getgrgid
1.71 fefe 924: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 925: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 926:
1.64 fefe 927: 0.8:
1.34 fefe 928: vsnprintf(0,...) estimated the length of strings with a padding width
929: incorrectly.
1.35 fefe 930: new reboot() from Olaf.
1.36 fefe 931: added prototypes for getsockopt and setsockopt.
1.39 fefe 932: added experimental sem* and shm*
1.38 fefe 933: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 934: added setvbuf (only changes mode, not buffer)
1.41 fefe 935: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
936: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 937: added qsort() and bsearch(). Benchmark on 1000 random ints:
938: glibc: 679414 cycles qsort and 3352 cycles bsearch
939: diet libc: 300010 cycles qsort, 553 cycles bsearch
940: I have no idea why glibc is so slow.
1.43 fefe 941: added __isnan (references by libm.a from glibc).
942: added popen() and pclose(). Now the diet libc can link slsh (from
943: S-Lang!)
1.44 fefe 944: corrected usleep. It was more of an msleep until now.
1.45 fefe 945: corrected __dtostr (it looped when trying to format "0.0").
946: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 947: added ungetc (does it work?)
1.47 fefe 948: added inet_aton (yuck!)
1.50 fefe 949: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 950: added h_errno and __h_errno_location
951: added inet_ntoa
1.49 fefe 952: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 953: add bcopy, index, rindex macros
954: add isgraph and isxdigit
1.52 fefe 955: add strftime (ugh!!!)
1.53 olaf 956: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 957: Jeff Garzik contributed a spec file. I put it in contrib and hope
958: everbody knows what to do with it...
959: Olaf checked in a ton of libpthread stuff.
1.55 fefe 960: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 961: add large file backwards compatibility support (so gzip will run on
962: kernel 2.2 and 2.0)
1.57 fefe 963: added shutdown
1.58 fefe 964: added nice
965: added pseudo-locale support for is* (they are now weak aliases,
966: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
967: overwrite the default is* functions.
1.59 fefe 968: added liblatin1.a
1.60 fefe 969: added tzfile implementation (does it work for anyone else?)
1.61 fefe 970: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 971: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
972: Thanks!
1.63 fefe 973: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 974:
1.21 fefe 975: 0.7.2:
976: added several prototypes to already implemented functions and
977: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 978: added prototypes for process group and dup syscalls. Thanks to
979: Abraham again. He also contributed an implementation for daemon(),
980: an ugly BSD hack. I decided to diversify the lib/ directory a
981: little and now created a libugly/ directory for stuff like system()
982: and daemon() ;-)
983: added libstdio and moved all that stdio crap from lib/ there. The
984: idea is to start separating now what we will separate for shared
985: libraries anyway.
1.26 fefe 986: optimized x86 unified-syscall by Olaf.
1.27 fefe 987: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
988: limits.h instead)
989: added remove.c and enough cruft to limits.h to make it compile lzo,
990: lzop and bzip2.
1.28 fefe 991: added mktime, asctime_r, asctime and ctime (needed for gzip).
992: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 993: format some day (man tzfile, ugh!) :-(
1.29 fefe 994: added unlink prototype to unistd.h.
995: added gmtime and gmtime_r.
1.31 fefe 996: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 997: removed readdir glibc compatibility cruft.
1.31 fefe 998: removed stat glibc compatibility cruft.
1.32 fefe 999: oops, my fread was broken for pipes.
1.33 fefe 1000: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1001:
1.9 fefe 1002: 0.7.1:
1.11 fefe 1003: optimized away the static arrays from __ltostr and __lltostr.
1004: optimized away the static arrays (and more!) from strtoul and strtoull.
1005: added system (by Olaf).
1.12 fefe 1006: added tolower and toupper
1.13 fefe 1007: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1008: added clone for mips (by Olaf).
1009: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1010: added pause for all (by Olaf).
1.17 fefe 1011: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1012: added isupper and islower.
1013: added putc and putchar as macros.
1.17 fefe 1014: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1015: insightful discussions and patches I partially used for the last three)
1.18 fefe 1016: added getpriority and setpriority (also by Abraham)
1.19 fefe 1017: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1018: oi, setjmp and longjmp were broken on other platforms, too!
1019: Thanks to Sébastien Côté for reporting this.
1.9 fefe 1020:
1021: 0.7:
1.6 olaf 1022: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1023: Initial dynamic loading glue for i386, also by Olaf.
1024: We don't have a dynamic loader yet, so this is not yet usable.
1025: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1026: vsprintf, writev, all by Olaf.
1.2 fefe 1027: imported readdir fix from Guillaume. Mhh, can the kernel interface
1028: really be this broken?
1.3 fefe 1029: Found a kludgy way to detect whether the kernel includes define struct
1030: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1031: not work for you, please tell me!
1.4 fefe 1032: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1033: Fixed stdio line buffering. The code was already there but I forgot
1034: to mark stdio and stdout as line buffered. This should really be
1035: done dynamically using isatty, though.
1.8 fefe 1036: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1037:
1038: 0.6.14:
1039: *scanf did not append the 0 byte for %s.
1040: added creat and changed creat to call open directly instead of open64.
1041: did for fread what 0.6.10 did for fwrite.
1042: repaired buffered stdio a little (line buffering is still not
1043: supported).
1044: [All of these bugs have been reported by Guillaume. Thanks!]
1045: added __pure__ to strchr and strrchr in <string.h>
1046:
1047: 0.6.13:
1048: included COPYING to make clear that the diet libc is covered by the
1049: GNU General Public License (and _not_ the LGPL). That means that
1050: you need to obtain a license from me if you want to use the diet
1051: libc in a proprietary program that you want to distribute.
1052: The x86 unified syscall swapped arguments #4 and #5 and noone
1053: noticed until now! Thanks to Guillaume Cottenceau for reporting
1054: this!
1055: The malloc had a subtle bug with small allocations that could cause
1056: segfault. Guillaume reported it, Olaf fixed it.
1057:
1058: 0.6.12:
1059: added assert, statfs and fstatfs
1060: added include/net/if.h so fget compiles again.
1061:
1062: 0.6.11:
1063: added putenv.
1064:
1065: 0.6.10:
1066: fixed fwrite. It returned the number of bytes written, not the number
1067: of records. Thanks to Albert D. Cahalan for pointing this out.
1068: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1069: added brk and sbrk. harold@nb.com.sg made me do it.
1070:
1071: 0.6.9:
1072: fixed execvp not to return on ENOENT
1073: did for {open|read|close|seek|tell}dir what I did for stat before.
1074: The glibc compatibility part is currently non-functional.
1075: fixed white space handling in sscanf " (" would not match " (".
1076: fixed printf to accept 'l' flag.
1077: fixed getpwuid (ignored last line)
1078:
1079: 0.6.8:
1080: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1081: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1082: added strlcpy and strlcat from OpenBSD.
1083: added stat64, fstat64 and lstat64.
1084: added endian.h and made ending of strlen.c endianness-aware
1085: added string routines size tweak to dietfeatures.h. Most of the
1086: string routines have been unrolled. This is up to three times as
1087: fast but creates up to three times larger code. Now you can disable
1088: the unrolling.
1089: added sendfile.
1090: I also added pread. It works on x86 and sparc but not on ppc and mips.
1091: I have no idea what's going on. strace disagrees with the kernel.
1092: Can anyone help? I asked the Linux kernel mailing list for help, too.
1093: added a few aliases of the type __libc_open for open. nm on
1094: libpthreads.so indicates that we will need them.
1095:
1096: 0.6.7:
1097: the sources now compile without warnings with -Wall.
1098: printf now prints "(null)" when %s is passed NULL. This can be
1099: removed with WANT_NULL_PRINTF in dietfeatures.h
1100: added vfprintf, execl, ttyname.
1101: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1102: __dietfstat so they can use the normal kernel struct stat.
1103: stat, lstat and fstat are now C wrappers that convert to the glibc
1104: struct stat. So we can avoid that overhead for programs that use
1105: dietlibc headers.
1106:
1107: 0.6.6:
1108: changed the Makefiles so you can now set CFLAGS on the command line
1109: added memccmp (analogous to memccpy) and strncmp.
1110: Olaf fixed another bug in the sparc unified syscall.
1111: Paul Clifford contributed a C version of his strlen.S that is much
1112: more efficient than the previous strlen on all platforms! It also
1113: looks like technology from Roswell. ;-}
1114: added a "real" stdio. Well, almost. Please contribute!
1115: added dietfeatures.h so you can remove features you don't need.
1116: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1117: stdio now works with simple programs and minigzip from libz.
1118: stdio uses some major trickery to avoid linking the stdio, stderr and
1119: stdout (and reserving space for them) when they are not used.
1120:
1121: 0.6.5:
1122: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1123: most of them bugs in the new header files, but also missing sigset
1124: functions.
1125: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1126: several bugs.
1127: Fixed ppc/setjmp and mips/pipe.
1128: Olaf contributed a new sparc unified syscall.
1129:
1130: 0.6.4:
1131: declared is* static inline in getservent.
1132: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1133: changed strlen to return 0 when passed NULL.
1134: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1135: Scientist who actually implemented this without access to a MIPS
1136: box, just from reading the architecture manual. And it worked out
1137: of the box.
1138: started a set of system includes, mainly so that I can use lcc and
1139: my alpha-linux cross compiler (which is unable to cross-compile
1140: glibc). diet libc can now be compiled without any include files
1141: from a normal libc. The includes do declare more than diet libc
1142: currently delivers and they are still far from complete for real
1143: applications.
1144: I will only add assembly versions that are smaller _and_ faster than
1145: the C version. Larger routines are only accepted if they are called
1146: very often and are substantially faster.
1147: added i386 assembly strchr, which is smaller and faster than the old
1148: version. It is, however, larger than the version contributed by
1149: proton (thanks, anyway).
1150: added i386 strlen (31% faster, 14% smaller)
1151: "make t" will now create a map file called "mapfile".
1152:
1153: 0.6.3:
1154: added sys_errlist, strerror and perror
1155: added isblank
1156: added atol
1157:
1158: 0.6.2:
1159: mmap for ARM didn't compile. Thanks, Paul!
1160:
1161: 0.6.1:
1162: split mmap into the architecture specific subdirectories.
1163: getenv now copes with environ==NULL, thanks Paul Clifford.
1164: Paul also contributed a smaller ARM startup code.
1165:
1166: 0.6:
1167: strcat returned the wrong result. Thanks, Dietz Pröpper.
1168: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1169: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1170: __dtostr does not work (I have no idea why!)
1171: The MIPS port now uses (much smaller) non-PIC code. That means that
1172: the applications you link against diet libc also have to be compiled
1173: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1174: Thanks to Ralf Bächle for helping me with this!
1175: I made subdirectories for the architectures and use VPATH to override
1176: VPATH so that make finds the source file automatically. That should
1177: simplify the sources greatly.
1178: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1179: ARM and MIPS now also have setjmp and longjmp
1180: "compile" and "load" are now make targets. Use them for djb programs.
1181: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1182: Again, contributed from Olaf. Great work!
1183:
1184: 0.5.12:
1185: printf also does signed numbers.
1186: If you don't use atexit, dietlibc now does not link exit, only _exit.
1187: *printf now correctly returns the number of bytes written.
1188: Olaf contributed experimental sscanf and vsscanf implementations.
1189: If passed NULL as buffer, snprintf will not write anything but still
1190: return the number of bytes it would have written.
1191: Initial MIPS port! (Oh, the agony!)
1192: No setjmp and longjmp support yet! Please contribute!
1193: I even implemented unified syscalls for MIPS. Still, MIPS code is
1194: almost twice the size of SPARC code. If anyone knows why: please
1195: tell me!
1196:
1197: 0.5.11:
1198: I implemented new unified syscalls for x86, sparc and ppc, this time based
1199: on .s files and not .c files, and I moved the syscalls into
1200: subdirectores to clean the dietlibc sources up a little.
1201: A binary consisting of printf("%s is %d\n","olaf",23) is now
1202: 2864 bytes on sparc
1203: 2488 bytes on intel
1204: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1205: to make a few more applications work.
1206: Olaf Dreesen also implemented some unified syscall stuff for x86.
1207: He discovered that with our unified syscall interface it actually
1208: costs <10 bytes total to make all system calls thread safe!
1209: I implemented atexit() (can register up to 4 callbacks).
1210: I implemented strtod and __dtostr (the opposite). Now we can add
1211: floating point support to vsnprintf and sscanf!
1212:
1213: 0.5.10:
1214: I actually saw that I can not only merge the errno handling code of
1215: the system calls on x86, I can also merge the rest (including the
1216: arguments) except for setting the system call number. All those
1217: system calls are now just a jump to a unified system call handler.
1218: I got rid of x86openclose again. The savings are substantial:
1219: chown from embutils went from 7664 to 7184 bytes!
1220: If I'd move the system call wrappers to assembly language, I could
1221: even reduce the alignment (does not matter since it's just a jump
1222: anyway) and get rid of the "ret" behind each jump (one byte per
1223: system call!)
1224:
1225: 0.5.9:
1226: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1227: fixed strdup
1228: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1229: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1230: (no signed integers, only strings and unsigned integers (but
1231: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1232: that code must be wonderful, I don't understand it at all *bg*)
1233: Olaf's printf does understand padding like in "%08d" and "%8d" and
1234: automatically pads pointers with '0'.
1235: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1236: Thanks to proton for inspiration on this.
1237: The new x86 start code also does not reference exit any more, thus saving
1238: 64 bytes for executables that don't call exit explicitly.
1239: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1240: Moved errno and environ to start.S, saving no byte binary size but
1241: speeding up compilation and slightly shortening dietlibc.a ;-)
1242: For x86: joined open and close into one assembler file, sharing the
1243: errno handling. This is a feasibility test and it actually saves a
1244: few bytes. I think I will reimplement the _syscall[1-6] macros on
1245: all platforms now to share the errno handling code for them.
1246:
1247: 0.5.8:
1248: fixed strchr to be able to look for 0.
1249:
1250: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1251: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1252: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1253: contributed by Olaf Dreesen)
1254:
1255: added execvp, getcwd
1256:
1257: fixed __xmknod
1258:
1259: Note: can it be that the ftw interface really is so broken that I
1260: cannot implement it without having to implement some searching data
1261: structure? I included an experimental ftw implementation that will
1262: not follow symlinks.
1263:
1264: 0.5.7:
1265: oops, if_nametoindex was broken!
1266:
1267: 0.5.6:
1268: ported to ppc-linux.
1269: fixed i386 sigsetjmp (I mistyped the function name)
1270: included sigjmp.c
1271:
1272: 0.5.5:
1273: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1274: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1275: I fixed it now.
1276: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1277: fixed readdir to use getdents and not the intel inline asm
1278:
1279: 0.5.4:
1280: ported to sparclinux (sparc32 only). Beware: does not work yet.
1281: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1282:
1283: 0.5.3:
1284: added tcsetattr and getenv to compile e3
1285:
1286: 0.5.2:
1287: added vhangup, tcgetattr, isatty and memcmp for fgetty
1288: (http://www.fefe.de/fgetty/)
1289: added localtime from uC-libc.
1290:
1291: 0.5.1:
1292: stat and friends actually work now. Yuck! Another case of
1293: translation between kernel and userland. Why can't the kernel
1294: people and the libc people simply agree on a standard?
1295: removed many unnecessary includes to speed up compilation.
1296: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1297: inlined socketcall to reduce code size.
1298: "load" and "compile" are examples for djb code.
1299:
1300: 0.5:
1301: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1302: each object file is now treated with "strip -x -R .note -R .comment"
1303: split each system call into a separate object file
1304: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1305:
1306: 0.4.1:
1307: oops, the strchr implementation was wrong. Thanks Jens Laas!
1308:
1309: 0.4:
1310: copied opendir and friends from uC-libc.
1311: added getservent and getservby* in gerservent.c
1312:
1313: 0.3:
1314: remove readdir system call
1315: added getdents system call
1316: added getpwnam/getpwuid implementation in getpwnam.c
1317: added a few string functions (in str*.c)
1318:
