1.333 fefe 492: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
493: the built-in defaults.

1.284 fefe 530: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 531: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 532: upcoming AMD Hammer chips!). You can't even buy the chips yet and
533: the diet libc already supports it! Amazing ;-)
534: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 535: Andre sent a patch to add ARM profiling. He says it does not work

664: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 665: getservent_r did not parse lines without aliases. Thanks, Jaroslav
666: Macodiseas!
1.240 fefe 667: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 668: removed annoying -Wconversion gcc switch
1.242 fefe 669: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 670: Kurt Garloff sent these diffs:
671: add fdatasync (and make it a pthread cancellation point)
672: numerous alpha issues, like using .quad instead of .long for
673: offsets, change strip to -strip in Makefile (so a failing strip does
674: not abort the make), try to be more friendly to the gcc 2.96 that
675: SuSE 7.1 AXP ships with.
1.224 fefe 676:
1.209 fefe 677: 0.14:
1.224 fefe 678: fix brk again (missing __brk, trivial oversight)
1.210 fefe 679: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
680: Thomas Ogrisegg!
1.211 fefe 681: Thomas also contributed a PA-RISC port including testandset, so
682: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 683: made the fake locale more believable.
684: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 685: moved _exit into the unified syscall on x86.
1.214 fefe 686: Uwe Ohse found many more bugs:
687: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
688: liblatin1 was more or less completely broken if you gave it chars as
689: arguments, not ints (signedness). execvp had a buffer overflow in
690: case a PATH element exceeded PATH_MAX, but it's not a security
691: problem since setuid programs need to set their path to some known
692: value anyway.
1.219 fefe 693: hasmntopt did not work with foo=bar style options
1.217 fefe 694: Uwe also improved ftw's stack usage.
1.214 fefe 695: Put movl instead of popl rationale in comment in i386/unified.S since
696: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 697: I discovered __attribute__((malloc)) and started using it. For gcc 3,
698: it improves the optimizer when functions return malloced pointers.
1.216 fefe 699: Steven Rostedt pointed out that my setvbuf was broken with regard to
700: size==0 and sent a patch to fix it.
1.218 fefe 701: Thomas Ogrisegg made setenv smaller.
1.220 olaf 702: Olaf: implemented the parisc clone and an atomic testandset, modified the
703: libpthread to respect the parisc UPgrowing stack. still non functional,
704: because the unified syscall uses errno :(
1.221 fefe 705: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 706: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
707: don't write anything which was no longer the case. It also
708: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 709: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 710:
1.193 fefe 711: 0.13:
1.194 fefe 712: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 713: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 714: Olaf: port to S/390!
1.463 leitner 715: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 716: res_query did not initialize last
1.199 fefe 717: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 718: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 719: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 720: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 721: rewrote __dtostr (it also has one more argument now)
1.205 fefe 722: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 723: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
724: fix strncat for the case where n == 0 (security implications?)
725: fix bsearch (it didn't find the very last element in the array, same
726: bug in both the C and the i386 assembly version).
1.205 fefe 727: fixed FNM_PATHNAME in fnmatch
1.204 fefe 728: fix brk (the syscall was documented incorrectly in the Linux man page)
729: Thanks, Thomas Ogrisegg!
1.205 fefe 730: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 731: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 732: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 733:
1.164 fefe 734: 0.12:
735: more contributions from Frank Klemm.
1.165 fefe 736: iconv can now do UCS-2, too.
1.167 fefe 737: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 738: Lots of bug fixes, and several more i386 specific versions of common
739: routines to make them smaller.
1.168 fefe 740: add memmem (a GNU extension that looks useful)
1.170 fefe 741: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 742: add pivot_root syscall, %n for *scanf.
1.169 fefe 743: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 744: add Frank Klemm's optimized md5
1.172 fefe 745: add -Os option to diet (see diet.1).
1.173 fefe 746: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 747: add 32-bit uid/gid syscalls.
1.175 fefe 748: add rand48 (thanks, Johannes Kloos)
1.176 fefe 749: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 750: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
751: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
752: fix gethostent alias list termination. Major oops.
1.178 fefe 753: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 754: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 755: DNS will now properly signal errors and set h_errno.
756: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 757: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
758: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
759: external reference to a symbol that is only in the diet libc. So,
760: when you accidentally link a diet libc compiled object file against
761: glibc, the linker will barf. This will bloat your object files, but
762: you can remove all the references with "strip -R .note" from
763: the binaries in the end (which you should do anyway).
1.182 fefe 764: fix ARM unified syscall (select did not work).
1.183 fefe 765: add getpwent_r ala glibc and replace getpwent
766: do the same for getgrent and getspent
767: remove entlib (new code is smaller)
1.184 fefe 768: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 769: add getpwnam_r and getpwuid_r
1.186 fefe 770: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 771: Olaf muddled with the dynamic linker. It's a clean-room
772: implementation in the sense that it once worked for Olaf in a clean
773: room ;)
1.188 fefe 774: add if_nameindex and if_freenameindex.
775: fixed arm unified syscalls to work with current binutils (; is no
776: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 777: changed all st_[cma]time types to signed long so comparisons against
778: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 779: fixed two bugs regarding ungetc.
780: add getusershell, setusershell, endusershell (for vs_ftpd)
781: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 782: fixed strftime (was completely hosed)
1.192 fefe 783: added real make install target
1.164 fefe 784:
1.115 fefe 785: 0.11:
786: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 787: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 788: add floor, ceil and memchr prototypes.
789: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 790: cleaner errno vs __errno_location handling
791: add placeholder iconv (iconv_open will always return EINVAL)
792: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
793: initialization of getaddrinfo.
1.119 fefe 794: fix vsnprintf %X (printed lower case)
1.120 fefe 795: I wrote a new getopt. It appears to actually work (it is POSIX
796: compliant, it does not sort argv like the GNU version) and is only
797: a little over 300 bytes on x86.
1.121 fefe 798: Guillaume Cottenceau just wrote me that strncat should be even more
799: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 800: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 801: Fix regexec offset return. autoconf now believes that diet libc has
802: POSIX regular expressions.
1.123 fefe 803: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 804: Fix regular expression match for x* when there is no x at all.
1.125 fefe 805: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 806: Add %h to vsnprintf.
1.127 fefe 807: Add FAQ.
1.128 fefe 808: Make %h work for signed numbers and add %hh to vsnprintf.
809: initgroups ignored the group argument :-(
810: remove printf references and nested functions from glob.
1.129 fefe 811: added an errno in libpthread that will display a prominent linker
812: warning.
1.131 fefe 813: started getting rid of kernel headers. Big task! :-(
1.130 fefe 814: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 815: Olaf: added a lot of code in libdl (not yet complete), changed the
816: startup code to make it work with his libdl and ld.so (needs still work
817: too)
1.134 fefe 818: __dns_readstartfiles only took the first domain or search path.
819: Thanks, Anthony de Boer
1.133 olaf 820: Olaf: added clone and a new unified_syscall for PowerPC
821: also dynlinker is now available (i386 only at this time)
1.135 fefe 822: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 823: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 824: fixed word delimiters in regex (they looked for space, i.e. "," did
825: not work as delimiter)
1.138 fefe 826: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 827: added mkdtemp.
1.142 fefe 828: Uwe Ohse reported all of the following bugs:
829: ttyname should return 0 if !isatty.
830: realpath returns NULL if "." cannot be opened
831: putenv erroneously accepted (and mishandled) entries without "=".
832: popen returned 255 instead of 127 if /bin/sh could not be run.
833: fgetc did not set the internal EOF indicator on EOF.
834: bsearch contained an assumption about integer arithmetic overflow
835: behavior.
836: system did not set SIGCHLD and thus contained a race.
837: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 838: daemon did not check whether open returns an fd below 3
839: perror did not save errno.
1.144 olaf 840: Olaf: Peter Jones reported some problems with perror; strerror had the
841: same problem.
842: Peter also posted a patch to atexit/exit. With some modifications it is
843: now implemented.
1.145 fefe 844: Unbuffered stdio and ungetc can no longer be disabled. I will try to
845: implement part of it using ELF weak symbols.
1.146 fefe 846: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 847: Added overflow handling for strtoul and strtol.
1.149 fefe 848: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
849: it before falling back to DNS if enabled.
1.150 fefe 850: Added a littie backwards compatibility cruft for gpm (man, do these
851: sources stink!)
1.151 fefe 852: Added openpty.
1.152 fefe 853: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 854: Fix fseek return value.
1.155 fefe 855: Add dirname and basename.
1.156 fefe 856: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 857: Fixed getservent (did not allow _ and - in the aliases).
858: Thanks, Oden Eriksson
1.158 fefe 859: Added a float.h so configure believes we have ANSI header files.
860: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 861: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 862: scanf and printf function implementations
1.160 fefe 863: Imported a few more functions and optimizations from Frank Klemm (he
864: also rewrote dtostr to have more precision)
1.161 olaf 865: Olaf: checked in a new sig* function family (based on rt_sig*).
866: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 867: Made rudimentary iconv that can convert back and forth between
868: iso-8859-1, utf-8 and ucs-4 (for debugging).
869: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 870:
1.74 fefe 871: 0.10:
872: update getpagesize.
873: add personality.
1.75 fefe 874: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 875: add putchar (apparently arm-linux-gcc will substitute printf("\n")
876: with putchar('\n') behind your back...?!
1.77 fefe 877: import include/scsi/ from glibc.
1.78 fefe 878: add iopl.
1.80 fefe 879: add execl and sigdelset prototypes.
880: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 881: add RPC headers (no code yet).
1.82 fefe 882: add mlockall, munlockall
1.83 fefe 883: make "diet gcc foo.c" work.
884: added Sun RPC code and removed as many warnings as possible in a
885: heroic act of self-mutilation.
886: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 887: added getpass. mount from util-linux actually compiles now!
888: fix the sig*set routines. mount actually works now *bg*
889: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 890: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 891: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 892: add res_init.
893: add asprintf (ugh, what an ugly function).
1.89 fefe 894: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 895: add ut_name alias to ut_host in struct utmp.
896: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 897: add sysinfo, recvmsg, sendmsg.
1.93 fefe 898: add endmntent, getmntent, setmntent.
1.94 fefe 899: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 900: add setenv.
901: remove __restrict from mntent.h, add __restrict__ removal alias for
902: older gcc versions in sys/cdefs.h.
903: add rlim_t, sig_atomic_t declarations.
904: add sigsetjmp #define for __sigsetjmp (oops).
905: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 906: add a gruesome hack to printf floating point to accept %f and kludge
907: together support for %.2f. Don't look at the code, please!
1.98 fefe 908: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 909: imported fix for entlib by Jeff Garzik.
1.100 fefe 910: add glob implementation from Guillaume Cottenceau (Thanks!!)
911: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 912: add REG_ICASE and word start/end handling to my regular expressions.
913: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 914: wrap getcwd to comply to man page (the syscall returns the number of
915: bytes, not the buffer)
916: add realpath.
1.103 fefe 917: fix vfprintf.
1.104 fefe 918: fix *scanf %s zero termination.
919: add abs, labs, llabs.
1.105 fefe 920: add <sys/io.h>, ioperm syscall.
921: add flock to <sys/file.h>
1.106 fefe 922: fixes to bsearch and the regular expressions.
1.107 fefe 923: add fake herror.
1.108 fefe 924: add scandir and alphasort.
1.109 fefe 925: add killpg
1.110 fefe 926: implemented a gross hack to make libpthread compile when
927: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 928: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 929: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 930: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
931: for sending a patch.
1.114 fefe 932: add getserv*.
933: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
934: "search" from resolv.conf.
1.74 fefe 935:
1.73 fefe 936: 0.9:
1.65 fefe 937: fixed initgroups (oops)
1.66 fefe 938: Cleanup appending file open for stdio (thanks, James Antill)
939: imported vfprintf fix from James Antill.
1.67 fefe 940: add fnmatch
941: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 942: Olaf added character classes to *scanf.
1.69 fefe 943: Put object and library files into a separate directory (bin-$ARCH).
944: Add "cross" make target to make all architectures.
945: Add "diet" program and man page.
1.70 fefe 946: Add getgrnam, getgrgid
1.71 fefe 947: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 948: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 949:
1.64 fefe 950: 0.8:
1.34 fefe 951: vsnprintf(0,...) estimated the length of strings with a padding width
952: incorrectly.
1.35 fefe 953: new reboot() from Olaf.
1.36 fefe 954: added prototypes for getsockopt and setsockopt.
1.39 fefe 955: added experimental sem* and shm*
1.38 fefe 956: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 957: added setvbuf (only changes mode, not buffer)
1.41 fefe 958: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
959: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 960: added qsort() and bsearch(). Benchmark on 1000 random ints:
961: glibc: 679414 cycles qsort and 3352 cycles bsearch
962: diet libc: 300010 cycles qsort, 553 cycles bsearch
963: I have no idea why glibc is so slow.
1.43 fefe 964: added __isnan (references by libm.a from glibc).
965: added popen() and pclose(). Now the diet libc can link slsh (from
966: S-Lang!)
1.44 fefe 967: corrected usleep. It was more of an msleep until now.
1.45 fefe 968: corrected __dtostr (it looped when trying to format "0.0").
969: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 970: added ungetc (does it work?)
1.47 fefe 971: added inet_aton (yuck!)
1.50 fefe 972: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 973: added h_errno and __h_errno_location
974: added inet_ntoa
1.49 fefe 975: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 976: add bcopy, index, rindex macros
977: add isgraph and isxdigit
1.52 fefe 978: add strftime (ugh!!!)
1.53 olaf 979: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 980: Jeff Garzik contributed a spec file. I put it in contrib and hope
981: everbody knows what to do with it...
982: Olaf checked in a ton of libpthread stuff.
1.55 fefe 983: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 984: add large file backwards compatibility support (so gzip will run on
985: kernel 2.2 and 2.0)
1.57 fefe 986: added shutdown
1.58 fefe 987: added nice
988: added pseudo-locale support for is* (they are now weak aliases,
989: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
990: overwrite the default is* functions.
1.59 fefe 991: added liblatin1.a
1.60 fefe 992: added tzfile implementation (does it work for anyone else?)
1.61 fefe 993: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 994: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
995: Thanks!
1.63 fefe 996: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 997:
1.21 fefe 998: 0.7.2:
999: added several prototypes to already implemented functions and
1000: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 1001: added prototypes for process group and dup syscalls. Thanks to
1002: Abraham again. He also contributed an implementation for daemon(),
1003: an ugly BSD hack. I decided to diversify the lib/ directory a
1004: little and now created a libugly/ directory for stuff like system()
1005: and daemon() ;-)
1006: added libstdio and moved all that stdio crap from lib/ there. The
1007: idea is to start separating now what we will separate for shared
1008: libraries anyway.
1.26 fefe 1009: optimized x86 unified-syscall by Olaf.
1.27 fefe 1010: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
1011: limits.h instead)
1012: added remove.c and enough cruft to limits.h to make it compile lzo,
1013: lzop and bzip2.
1.28 fefe 1014: added mktime, asctime_r, asctime and ctime (needed for gzip).
1015: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 1016: format some day (man tzfile, ugh!) :-(
1.29 fefe 1017: added unlink prototype to unistd.h.
1018: added gmtime and gmtime_r.
1.31 fefe 1019: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 1020: removed readdir glibc compatibility cruft.
1.31 fefe 1021: removed stat glibc compatibility cruft.
1.32 fefe 1022: oops, my fread was broken for pipes.
1.33 fefe 1023: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1024:
1.9 fefe 1025: 0.7.1:
1.11 fefe 1026: optimized away the static arrays from __ltostr and __lltostr.
1027: optimized away the static arrays (and more!) from strtoul and strtoull.
1028: added system (by Olaf).
1.12 fefe 1029: added tolower and toupper
1.13 fefe 1030: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1031: added clone for mips (by Olaf).
1032: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1033: added pause for all (by Olaf).
1.17 fefe 1034: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1035: added isupper and islower.
1036: added putc and putchar as macros.
1.17 fefe 1037: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1038: insightful discussions and patches I partially used for the last three)
1.18 fefe 1039: added getpriority and setpriority (also by Abraham)
1.19 fefe 1040: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1041: oi, setjmp and longjmp were broken on other platforms, too!
1042: Thanks to Sébastien Côté for reporting this.
1.9 fefe 1043:
1044: 0.7:
1.6 olaf 1045: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1046: Initial dynamic loading glue for i386, also by Olaf.
1047: We don't have a dynamic loader yet, so this is not yet usable.
1048: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1049: vsprintf, writev, all by Olaf.
1.2 fefe 1050: imported readdir fix from Guillaume. Mhh, can the kernel interface
1051: really be this broken?
1.3 fefe 1052: Found a kludgy way to detect whether the kernel includes define struct
1053: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1054: not work for you, please tell me!
1.4 fefe 1055: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1056: Fixed stdio line buffering. The code was already there but I forgot
1057: to mark stdio and stdout as line buffered. This should really be
1058: done dynamically using isatty, though.
1.8 fefe 1059: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1060:
1061: 0.6.14:
1062: *scanf did not append the 0 byte for %s.
1063: added creat and changed creat to call open directly instead of open64.
1064: did for fread what 0.6.10 did for fwrite.
1065: repaired buffered stdio a little (line buffering is still not
1066: supported).
1067: [All of these bugs have been reported by Guillaume. Thanks!]
1068: added __pure__ to strchr and strrchr in <string.h>
1069:
1070: 0.6.13:
1071: included COPYING to make clear that the diet libc is covered by the
1072: GNU General Public License (and _not_ the LGPL). That means that
1073: you need to obtain a license from me if you want to use the diet
1074: libc in a proprietary program that you want to distribute.
1075: The x86 unified syscall swapped arguments #4 and #5 and noone
1076: noticed until now! Thanks to Guillaume Cottenceau for reporting
1077: this!
1078: The malloc had a subtle bug with small allocations that could cause
1079: segfault. Guillaume reported it, Olaf fixed it.
1080:
1081: 0.6.12:
1082: added assert, statfs and fstatfs
1083: added include/net/if.h so fget compiles again.
1084:
1085: 0.6.11:
1086: added putenv.
1087:
1088: 0.6.10:
1089: fixed fwrite. It returned the number of bytes written, not the number
1090: of records. Thanks to Albert D. Cahalan for pointing this out.
1091: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1092: added brk and sbrk. harold@nb.com.sg made me do it.
1093:
1094: 0.6.9:
1095: fixed execvp not to return on ENOENT
1096: did for {open|read|close|seek|tell}dir what I did for stat before.
1097: The glibc compatibility part is currently non-functional.
1098: fixed white space handling in sscanf " (" would not match " (".
1099: fixed printf to accept 'l' flag.
1100: fixed getpwuid (ignored last line)
1101:
1102: 0.6.8:
1103: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1104: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1105: added strlcpy and strlcat from OpenBSD.
1106: added stat64, fstat64 and lstat64.
1107: added endian.h and made ending of strlen.c endianness-aware
1108: added string routines size tweak to dietfeatures.h. Most of the
1109: string routines have been unrolled. This is up to three times as
1110: fast but creates up to three times larger code. Now you can disable
1111: the unrolling.
1112: added sendfile.
1113: I also added pread. It works on x86 and sparc but not on ppc and mips.
1114: I have no idea what's going on. strace disagrees with the kernel.
1115: Can anyone help? I asked the Linux kernel mailing list for help, too.
1116: added a few aliases of the type __libc_open for open. nm on
1117: libpthreads.so indicates that we will need them.
1118:
1119: 0.6.7:
1120: the sources now compile without warnings with -Wall.
1121: printf now prints "(null)" when %s is passed NULL. This can be
1122: removed with WANT_NULL_PRINTF in dietfeatures.h
1123: added vfprintf, execl, ttyname.
1124: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1125: __dietfstat so they can use the normal kernel struct stat.
1126: stat, lstat and fstat are now C wrappers that convert to the glibc
1127: struct stat. So we can avoid that overhead for programs that use
1128: dietlibc headers.
1129:
1130: 0.6.6:
1131: changed the Makefiles so you can now set CFLAGS on the command line
1132: added memccmp (analogous to memccpy) and strncmp.
1133: Olaf fixed another bug in the sparc unified syscall.
1134: Paul Clifford contributed a C version of his strlen.S that is much
1135: more efficient than the previous strlen on all platforms! It also
1136: looks like technology from Roswell. ;-}
1137: added a "real" stdio. Well, almost. Please contribute!
1138: added dietfeatures.h so you can remove features you don't need.
1139: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1140: stdio now works with simple programs and minigzip from libz.
1141: stdio uses some major trickery to avoid linking the stdio, stderr and
1142: stdout (and reserving space for them) when they are not used.
1143:
1144: 0.6.5:
1145: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1146: most of them bugs in the new header files, but also missing sigset
1147: functions.
1148: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1149: several bugs.
1150: Fixed ppc/setjmp and mips/pipe.
1151: Olaf contributed a new sparc unified syscall.
1152:
1153: 0.6.4:
1154: declared is* static inline in getservent.
1155: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1156: changed strlen to return 0 when passed NULL.
1157: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1158: Scientist who actually implemented this without access to a MIPS
1159: box, just from reading the architecture manual. And it worked out
1160: of the box.
1161: started a set of system includes, mainly so that I can use lcc and
1162: my alpha-linux cross compiler (which is unable to cross-compile
1163: glibc). diet libc can now be compiled without any include files
1164: from a normal libc. The includes do declare more than diet libc
1165: currently delivers and they are still far from complete for real
1166: applications.
1167: I will only add assembly versions that are smaller _and_ faster than
1168: the C version. Larger routines are only accepted if they are called
1169: very often and are substantially faster.
1170: added i386 assembly strchr, which is smaller and faster than the old
1171: version. It is, however, larger than the version contributed by
1172: proton (thanks, anyway).
1173: added i386 strlen (31% faster, 14% smaller)
1174: "make t" will now create a map file called "mapfile".
1175:
1176: 0.6.3:
1177: added sys_errlist, strerror and perror
1178: added isblank
1179: added atol
1180:
1181: 0.6.2:
1182: mmap for ARM didn't compile. Thanks, Paul!
1183:
1184: 0.6.1:
1185: split mmap into the architecture specific subdirectories.
1186: getenv now copes with environ==NULL, thanks Paul Clifford.
1187: Paul also contributed a smaller ARM startup code.
1188:
1189: 0.6:
1190: strcat returned the wrong result. Thanks, Dietz Pröpper.
1191: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1192: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1193: __dtostr does not work (I have no idea why!)
1194: The MIPS port now uses (much smaller) non-PIC code. That means that
1195: the applications you link against diet libc also have to be compiled
1196: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1197: Thanks to Ralf Bächle for helping me with this!
1198: I made subdirectories for the architectures and use VPATH to override
1199: VPATH so that make finds the source file automatically. That should
1200: simplify the sources greatly.
1201: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1202: ARM and MIPS now also have setjmp and longjmp
1203: "compile" and "load" are now make targets. Use them for djb programs.
1204: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1205: Again, contributed from Olaf. Great work!
1206:
1207: 0.5.12:
1208: printf also does signed numbers.
1209: If you don't use atexit, dietlibc now does not link exit, only _exit.
1210: *printf now correctly returns the number of bytes written.
1211: Olaf contributed experimental sscanf and vsscanf implementations.
1212: If passed NULL as buffer, snprintf will not write anything but still
1213: return the number of bytes it would have written.
1214: Initial MIPS port! (Oh, the agony!)
1215: No setjmp and longjmp support yet! Please contribute!
1216: I even implemented unified syscalls for MIPS. Still, MIPS code is
1217: almost twice the size of SPARC code. If anyone knows why: please
1218: tell me!
1219:
1220: 0.5.11:
1221: I implemented new unified syscalls for x86, sparc and ppc, this time based
1222: on .s files and not .c files, and I moved the syscalls into
1223: subdirectores to clean the dietlibc sources up a little.
1224: A binary consisting of printf("%s is %d\n","olaf",23) is now
1225: 2864 bytes on sparc
1226: 2488 bytes on intel
1227: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1228: to make a few more applications work.
1229: Olaf Dreesen also implemented some unified syscall stuff for x86.
1230: He discovered that with our unified syscall interface it actually
1231: costs <10 bytes total to make all system calls thread safe!
1232: I implemented atexit() (can register up to 4 callbacks).
1233: I implemented strtod and __dtostr (the opposite). Now we can add
1234: floating point support to vsnprintf and sscanf!
1235:
1236: 0.5.10:
1237: I actually saw that I can not only merge the errno handling code of
1238: the system calls on x86, I can also merge the rest (including the
1239: arguments) except for setting the system call number. All those
1240: system calls are now just a jump to a unified system call handler.
1241: I got rid of x86openclose again. The savings are substantial:
1242: chown from embutils went from 7664 to 7184 bytes!
1243: If I'd move the system call wrappers to assembly language, I could
1244: even reduce the alignment (does not matter since it's just a jump
1245: anyway) and get rid of the "ret" behind each jump (one byte per
1246: system call!)
1247:
1248: 0.5.9:
1249: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1250: fixed strdup
1251: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1252: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1253: (no signed integers, only strings and unsigned integers (but
1254: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1255: that code must be wonderful, I don't understand it at all *bg*)
1256: Olaf's printf does understand padding like in "%08d" and "%8d" and
1257: automatically pads pointers with '0'.
1258: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1259: Thanks to proton for inspiration on this.
1260: The new x86 start code also does not reference exit any more, thus saving
1261: 64 bytes for executables that don't call exit explicitly.
1262: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1263: Moved errno and environ to start.S, saving no byte binary size but
1264: speeding up compilation and slightly shortening dietlibc.a ;-)
1265: For x86: joined open and close into one assembler file, sharing the
1266: errno handling. This is a feasibility test and it actually saves a
1267: few bytes. I think I will reimplement the _syscall[1-6] macros on
1268: all platforms now to share the errno handling code for them.
1269:
1270: 0.5.8:
1271: fixed strchr to be able to look for 0.
1272:
1273: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1274: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1275: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1276: contributed by Olaf Dreesen)
1277:
1278: added execvp, getcwd
1279:
1280: fixed __xmknod
1281:
1282: Note: can it be that the ftw interface really is so broken that I
1283: cannot implement it without having to implement some searching data
1284: structure? I included an experimental ftw implementation that will
1285: not follow symlinks.
1286:
1287: 0.5.7:
1288: oops, if_nametoindex was broken!
1289:
1290: 0.5.6:
1291: ported to ppc-linux.
1292: fixed i386 sigsetjmp (I mistyped the function name)
1293: included sigjmp.c
1294:
1295: 0.5.5:
1296: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1297: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1298: I fixed it now.
1299: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1300: fixed readdir to use getdents and not the intel inline asm
1301:
1302: 0.5.4:
1303: ported to sparclinux (sparc32 only). Beware: does not work yet.
1304: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1305:
1306: 0.5.3:
1307: added tcsetattr and getenv to compile e3
1308:
1309: 0.5.2:
1310: added vhangup, tcgetattr, isatty and memcmp for fgetty
1311: (http://www.fefe.de/fgetty/)
1312: added localtime from uC-libc.
1313:
1314: 0.5.1:
1315: stat and friends actually work now. Yuck! Another case of
1316: translation between kernel and userland. Why can't the kernel
1317: people and the libc people simply agree on a standard?
1318: removed many unnecessary includes to speed up compilation.
1319: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1320: inlined socketcall to reduce code size.
1321: "load" and "compile" are examples for djb code.
1322:
1323: 0.5:
1324: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1325: each object file is now treated with "strip -x -R .note -R .comment"
1326: split each system call into a separate object file
1327: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1328:
1329: 0.4.1:
1330: oops, the strchr implementation was wrong. Thanks Jens Laas!
1331:
1332: 0.4:
1333: copied opendir and friends from uC-libc.
1334: added getservent and getservby* in gerservent.c
1335:
1336: 0.3:
1337: remove readdir system call
1338: added getdents system call
1339: added getpwnam/getpwuid implementation in getpwnam.c
1340: added a few string functions (in str*.c)
1341:
