400: unfair methods? People, if you find bugs, tell us!
401: Fixed fputc and freopen (found in busybox comments)
1.381 fefe 402:

430: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 431: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
432: the instruction before the syscall to be a load immediate)
433: fix fread() from a pipe (oops, tried to lseek)
1.362 fefe 434: #define _POSIX_VDISABLE in termios.h (Laurent Bercot)

462: but use them to fill in the struct hostent directly.
1.332 olaf 463: signal is now a correct signal (Olaf)
1.333 fefe 464: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
465: the built-in defaults.
1.334 fefe 466: add file "SECURITY". I will document design tradeoffs that have
467: security implications there.

501: there?)
1.284 fefe 502: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 503: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 504: upcoming AMD Hammer chips!). You can't even buy the chips yet and
505: the diet libc already supports it! Amazing ;-)
506: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 507: Andre sent a patch to add ARM profiling. He says it does not work
508: yet, but it's a start.

546: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 547: Thomas also sent me profiling support (so far only on x86, but
548: profiling/PORTING describes what needs to be done for other
549: architectures)!
1.272 fefe 550: add contrib/dprof.c, also from Thomas.
1.269 fefe 551: Andreas Krennmair sent a patch to add the BSD regex interface to
552: libcompat

1.279 fefe 561: fix DNS domain search
1.280 fefe 562: i386 memccpy exchanged esi and edi :-( I should do more checks before
563: accepting external code...
1.264 fefe 564:
1.244 fefe 565: 0.16:
566: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 567: Andre found two very embarassing bugs in my four lines of md5 glue.
568: I need to get more sleep.
1.247 fefe 569: Thanks Ogrisegg found that ptrace does not work as documented and
570: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 571: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
572: fix ptrace.h for S/390 and ARM
573: provide a PORTING document so we don't lose track of which file need
574: to be touched to port the diet libc to a new platform.
1.249 fefe 575: remove a few warnings
576: provide a prototype for usleep.
1.250 fefe 577: make __dtostr work on ARM by using long instead of long long.
578: Idea by Dirk Engling.
1.251 fefe 579: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 580: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 581: Kurt Garloff sent in patches to

584: create libcompat.a (and move daemon to it)
1.255 fefe 585: add getdelim and getline
586: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 587: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 588: Olaf: fixed *scanf familie. It hadn't wored with "long long".

1.244 fefe 596:
1.224 fefe 597: 0.15:
1.225 fefe 598: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 599: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 600: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
601: thread-safe!
1.228 fefe 602: remove vfork and add alarm to dynamic syscalls.
603: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 604: The MD5 code generated unaligned accesses when passed an unaligned
605: pointer on little endian ARM and MIPS.
606: MIPS unified syscall didn't compile anymore.
607: Put up new mipsel target to cross compile for little endian mips.
608: The mips target will again explicitly set endianness to big endian.
609: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 610: Duh, when we removed return0, we broke tzset when the time zone parser
611: was disabled. Uwe Ohse noticed this. Thanks!
612: Fix gethostbyname to match host names case insensitively in /etc/hosts.
613: Oops, this was reported 6 weeks ago but I overlooked the email.
614: Thanks, Denis Rachal!

1.233 fefe 616: Uwe Ohse found a few more bugs:
617: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
618: does it correctly.
619: Make inet_aton use strtoul instead of strtol
620: fdopen would close the file descriptor if it could not malloc the
621: buffer.
622: strftime updates.
623: Make _FILE_OFFSET_BITS includes -Wundef clean
624: Andre found a typo in endian.h for big endian mips
1.234 fefe 625: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 626: strstr(whatever,"") returned NULL, not whatever. Found by a new test
627: suite entry for strstr that I wrote.
1.245 fefe 628: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 629: add <asm/sigcontext.h> for profiling support.
630: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 631: an i386 assembler getenv implementation (roughly half the size)
632: add grantpt, ptsname, unlockpt
1.236 fefe 633: add a getenv test suite entry.
1.238 fefe 634: Andre contributed an ARM assembler md5 implementation and he fixed mmap
635: on ARM.
636: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 637: getservent_r did not parse lines without aliases. Thanks, Jaroslav
638: Macodiseas!
1.240 fefe 639: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 640: removed annoying -Wconversion gcc switch
1.242 fefe 641: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 642: Kurt Garloff sent these diffs:
643: add fdatasync (and make it a pthread cancellation point)
644: numerous alpha issues, like using .quad instead of .long for
645: offsets, change strip to -strip in Makefile (so a failing strip does
646: not abort the make), try to be more friendly to the gcc 2.96 that
647: SuSE 7.1 AXP ships with.
1.224 fefe 648:
1.209 fefe 649: 0.14:
1.224 fefe 650: fix brk again (missing __brk, trivial oversight)
1.210 fefe 651: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
652: Thomas Ogrisegg!
1.211 fefe 653: Thomas also contributed a PA-RISC port including testandset, so
654: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 655: made the fake locale more believable.
656: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 657: moved _exit into the unified syscall on x86.
1.214 fefe 658: Uwe Ohse found many more bugs:
659: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
660: liblatin1 was more or less completely broken if you gave it chars as
661: arguments, not ints (signedness). execvp had a buffer overflow in
662: case a PATH element exceeded PATH_MAX, but it's not a security
663: problem since setuid programs need to set their path to some known
664: value anyway.
1.219 fefe 665: hasmntopt did not work with foo=bar style options
1.217 fefe 666: Uwe also improved ftw's stack usage.
1.214 fefe 667: Put movl instead of popl rationale in comment in i386/unified.S since
668: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 669: I discovered __attribute__((malloc)) and started using it. For gcc 3,
670: it improves the optimizer when functions return malloced pointers.
1.216 fefe 671: Steven Rostedt pointed out that my setvbuf was broken with regard to
672: size==0 and sent a patch to fix it.
1.218 fefe 673: Thomas Ogrisegg made setenv smaller.
1.220 olaf 674: Olaf: implemented the parisc clone and an atomic testandset, modified the
675: libpthread to respect the parisc UPgrowing stack. still non functional,
676: because the unified syscall uses errno :(
1.221 fefe 677: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 678: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
679: don't write anything which was no longer the case. It also
680: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 681: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 682:
1.193 fefe 683: 0.13:
1.194 fefe 684: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 685: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 686: Olaf: port to S/390!
1.463 leitner 687: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 688: res_query did not initialize last
1.199 fefe 689: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 690: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 691: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 692: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 693: rewrote __dtostr (it also has one more argument now)
1.205 fefe 694: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 695: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
696: fix strncat for the case where n == 0 (security implications?)
697: fix bsearch (it didn't find the very last element in the array, same
698: bug in both the C and the i386 assembly version).
1.205 fefe 699: fixed FNM_PATHNAME in fnmatch
1.204 fefe 700: fix brk (the syscall was documented incorrectly in the Linux man page)
701: Thanks, Thomas Ogrisegg!
1.205 fefe 702: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 703: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 704: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 705:
1.164 fefe 706: 0.12:
707: more contributions from Frank Klemm.
1.165 fefe 708: iconv can now do UCS-2, too.
1.167 fefe 709: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 710: Lots of bug fixes, and several more i386 specific versions of common
711: routines to make them smaller.
1.168 fefe 712: add memmem (a GNU extension that looks useful)
1.170 fefe 713: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 714: add pivot_root syscall, %n for *scanf.
1.169 fefe 715: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 716: add Frank Klemm's optimized md5
1.172 fefe 717: add -Os option to diet (see diet.1).
1.173 fefe 718: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 719: add 32-bit uid/gid syscalls.
1.175 fefe 720: add rand48 (thanks, Johannes Kloos)
1.176 fefe 721: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 722: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
723: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
724: fix gethostent alias list termination. Major oops.
1.178 fefe 725: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 726: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 727: DNS will now properly signal errors and set h_errno.
728: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 729: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
730: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
731: external reference to a symbol that is only in the diet libc. So,
732: when you accidentally link a diet libc compiled object file against
733: glibc, the linker will barf. This will bloat your object files, but
734: you can remove all the references with "strip -R .note" from
735: the binaries in the end (which you should do anyway).
1.182 fefe 736: fix ARM unified syscall (select did not work).
1.183 fefe 737: add getpwent_r ala glibc and replace getpwent
738: do the same for getgrent and getspent
739: remove entlib (new code is smaller)
1.184 fefe 740: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 741: add getpwnam_r and getpwuid_r
1.186 fefe 742: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 743: Olaf muddled with the dynamic linker. It's a clean-room
744: implementation in the sense that it once worked for Olaf in a clean
745: room ;)
1.188 fefe 746: add if_nameindex and if_freenameindex.
747: fixed arm unified syscalls to work with current binutils (; is no
748: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 749: changed all st_[cma]time types to signed long so comparisons against
750: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 751: fixed two bugs regarding ungetc.
752: add getusershell, setusershell, endusershell (for vs_ftpd)
753: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 754: fixed strftime (was completely hosed)
1.192 fefe 755: added real make install target
1.164 fefe 756:
1.115 fefe 757: 0.11:
758: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 759: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 760: add floor, ceil and memchr prototypes.
761: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 762: cleaner errno vs __errno_location handling
763: add placeholder iconv (iconv_open will always return EINVAL)
764: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
765: initialization of getaddrinfo.
1.119 fefe 766: fix vsnprintf %X (printed lower case)
1.120 fefe 767: I wrote a new getopt. It appears to actually work (it is POSIX
768: compliant, it does not sort argv like the GNU version) and is only
769: a little over 300 bytes on x86.
1.121 fefe 770: Guillaume Cottenceau just wrote me that strncat should be even more
771: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 772: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 773: Fix regexec offset return. autoconf now believes that diet libc has
774: POSIX regular expressions.
1.123 fefe 775: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 776: Fix regular expression match for x* when there is no x at all.
1.125 fefe 777: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 778: Add %h to vsnprintf.
1.127 fefe 779: Add FAQ.
1.128 fefe 780: Make %h work for signed numbers and add %hh to vsnprintf.
781: initgroups ignored the group argument :-(
782: remove printf references and nested functions from glob.
1.129 fefe 783: added an errno in libpthread that will display a prominent linker
784: warning.
1.131 fefe 785: started getting rid of kernel headers. Big task! :-(
1.130 fefe 786: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 787: Olaf: added a lot of code in libdl (not yet complete), changed the
788: startup code to make it work with his libdl and ld.so (needs still work
789: too)
1.134 fefe 790: __dns_readstartfiles only took the first domain or search path.
791: Thanks, Anthony de Boer
1.133 olaf 792: Olaf: added clone and a new unified_syscall for PowerPC
793: also dynlinker is now available (i386 only at this time)
1.135 fefe 794: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 795: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 796: fixed word delimiters in regex (they looked for space, i.e. "," did
797: not work as delimiter)
1.138 fefe 798: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 799: added mkdtemp.
1.142 fefe 800: Uwe Ohse reported all of the following bugs:
801: ttyname should return 0 if !isatty.
802: realpath returns NULL if "." cannot be opened
803: putenv erroneously accepted (and mishandled) entries without "=".
804: popen returned 255 instead of 127 if /bin/sh could not be run.
805: fgetc did not set the internal EOF indicator on EOF.
806: bsearch contained an assumption about integer arithmetic overflow
807: behavior.
808: system did not set SIGCHLD and thus contained a race.
809: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 810: daemon did not check whether open returns an fd below 3
811: perror did not save errno.
1.144 olaf 812: Olaf: Peter Jones reported some problems with perror; strerror had the
813: same problem.
814: Peter also posted a patch to atexit/exit. With some modifications it is
815: now implemented.
1.145 fefe 816: Unbuffered stdio and ungetc can no longer be disabled. I will try to
817: implement part of it using ELF weak symbols.
1.146 fefe 818: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 819: Added overflow handling for strtoul and strtol.
1.149 fefe 820: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
821: it before falling back to DNS if enabled.
1.150 fefe 822: Added a littie backwards compatibility cruft for gpm (man, do these
823: sources stink!)
1.151 fefe 824: Added openpty.
1.152 fefe 825: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 826: Fix fseek return value.
1.155 fefe 827: Add dirname and basename.
1.156 fefe 828: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 829: Fixed getservent (did not allow _ and - in the aliases).
830: Thanks, Oden Eriksson
1.158 fefe 831: Added a float.h so configure believes we have ANSI header files.
832: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 833: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 834: scanf and printf function implementations
1.160 fefe 835: Imported a few more functions and optimizations from Frank Klemm (he
836: also rewrote dtostr to have more precision)
1.161 olaf 837: Olaf: checked in a new sig* function family (based on rt_sig*).
838: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 839: Made rudimentary iconv that can convert back and forth between
840: iso-8859-1, utf-8 and ucs-4 (for debugging).
841: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 842:
1.74 fefe 843: 0.10:
844: update getpagesize.
845: add personality.
1.75 fefe 846: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 847: add putchar (apparently arm-linux-gcc will substitute printf("\n")
848: with putchar('\n') behind your back...?!
1.77 fefe 849: import include/scsi/ from glibc.
1.78 fefe 850: add iopl.
1.80 fefe 851: add execl and sigdelset prototypes.
852: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 853: add RPC headers (no code yet).
1.82 fefe 854: add mlockall, munlockall
1.83 fefe 855: make "diet gcc foo.c" work.
856: added Sun RPC code and removed as many warnings as possible in a
857: heroic act of self-mutilation.
858: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 859: added getpass. mount from util-linux actually compiles now!
860: fix the sig*set routines. mount actually works now *bg*
861: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 862: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 863: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 864: add res_init.
865: add asprintf (ugh, what an ugly function).
1.89 fefe 866: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 867: add ut_name alias to ut_host in struct utmp.
868: add inet_ntop, inet_pton, gethostbyname2.

1.94 fefe 871: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 872: add setenv.
873: remove __restrict from mntent.h, add __restrict__ removal alias for
874: older gcc versions in sys/cdefs.h.
875: add rlim_t, sig_atomic_t declarations.
876: add sigsetjmp #define for __sigsetjmp (oops).
877: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 878: add a gruesome hack to printf floating point to accept %f and kludge
879: together support for %.2f. Don't look at the code, please!
1.98 fefe 880: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 881: imported fix for entlib by Jeff Garzik.
1.100 fefe 882: add glob implementation from Guillaume Cottenceau (Thanks!!)
883: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 884: add REG_ICASE and word start/end handling to my regular expressions.
885: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 886: wrap getcwd to comply to man page (the syscall returns the number of
887: bytes, not the buffer)
888: add realpath.
1.103 fefe 889: fix vfprintf.
1.104 fefe 890: fix *scanf %s zero termination.
891: add abs, labs, llabs.
1.105 fefe 892: add <sys/io.h>, ioperm syscall.
893: add flock to <sys/file.h>
1.106 fefe 894: fixes to bsearch and the regular expressions.
1.107 fefe 895: add fake herror.
1.108 fefe 896: add scandir and alphasort.
1.109 fefe 897: add killpg
1.110 fefe 898: implemented a gross hack to make libpthread compile when
899: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 900: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 901: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 902: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
903: for sending a patch.
1.114 fefe 904: add getserv*.
905: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
906: "search" from resolv.conf.
1.74 fefe 907:
1.73 fefe 908: 0.9:
1.65 fefe 909: fixed initgroups (oops)
1.66 fefe 910: Cleanup appending file open for stdio (thanks, James Antill)
911: imported vfprintf fix from James Antill.
1.67 fefe 912: add fnmatch
913: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 914: Olaf added character classes to *scanf.
1.69 fefe 915: Put object and library files into a separate directory (bin-$ARCH).
916: Add "cross" make target to make all architectures.
917: Add "diet" program and man page.
1.70 fefe 918: Add getgrnam, getgrgid
1.71 fefe 919: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 920: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 921:
1.64 fefe 922: 0.8:
1.34 fefe 923: vsnprintf(0,...) estimated the length of strings with a padding width
924: incorrectly.
1.35 fefe 925: new reboot() from Olaf.
1.36 fefe 926: added prototypes for getsockopt and setsockopt.
1.39 fefe 927: added experimental sem* and shm*
1.38 fefe 928: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 929: added setvbuf (only changes mode, not buffer)
1.41 fefe 930: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
931: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 932: added qsort() and bsearch(). Benchmark on 1000 random ints:
933: glibc: 679414 cycles qsort and 3352 cycles bsearch
934: diet libc: 300010 cycles qsort, 553 cycles bsearch
935: I have no idea why glibc is so slow.
1.43 fefe 936: added __isnan (references by libm.a from glibc).
937: added popen() and pclose(). Now the diet libc can link slsh (from
938: S-Lang!)
1.44 fefe 939: corrected usleep. It was more of an msleep until now.
1.45 fefe 940: corrected __dtostr (it looped when trying to format "0.0").
941: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 942: added ungetc (does it work?)
1.47 fefe 943: added inet_aton (yuck!)
1.50 fefe 944: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 945: added h_errno and __h_errno_location
946: added inet_ntoa
1.49 fefe 947: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 948: add bcopy, index, rindex macros
949: add isgraph and isxdigit
1.52 fefe 950: add strftime (ugh!!!)
1.53 olaf 951: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 952: Jeff Garzik contributed a spec file. I put it in contrib and hope
953: everbody knows what to do with it...
954: Olaf checked in a ton of libpthread stuff.
1.55 fefe 955: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 956: add large file backwards compatibility support (so gzip will run on
957: kernel 2.2 and 2.0)
1.57 fefe 958: added shutdown
1.58 fefe 959: added nice
960: added pseudo-locale support for is* (they are now weak aliases,
961: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
962: overwrite the default is* functions.
1.59 fefe 963: added liblatin1.a
1.60 fefe 964: added tzfile implementation (does it work for anyone else?)
1.61 fefe 965: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 966: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
967: Thanks!
1.63 fefe 968: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 969:
1.21 fefe 970: 0.7.2:
971: added several prototypes to already implemented functions and
972: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 973: added prototypes for process group and dup syscalls. Thanks to
974: Abraham again. He also contributed an implementation for daemon(),
975: an ugly BSD hack. I decided to diversify the lib/ directory a
976: little and now created a libugly/ directory for stuff like system()
977: and daemon() ;-)
978: added libstdio and moved all that stdio crap from lib/ there. The
979: idea is to start separating now what we will separate for shared
980: libraries anyway.
1.26 fefe 981: optimized x86 unified-syscall by Olaf.
1.27 fefe 982: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
983: limits.h instead)
984: added remove.c and enough cruft to limits.h to make it compile lzo,
985: lzop and bzip2.
1.28 fefe 986: added mktime, asctime_r, asctime and ctime (needed for gzip).
987: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 988: format some day (man tzfile, ugh!) :-(
1.29 fefe 989: added unlink prototype to unistd.h.
990: added gmtime and gmtime_r.
1.31 fefe 991: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 992: removed readdir glibc compatibility cruft.
1.31 fefe 993: removed stat glibc compatibility cruft.
1.32 fefe 994: oops, my fread was broken for pipes.
1.33 fefe 995: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 996:
1.9 fefe 997: 0.7.1:
1.11 fefe 998: optimized away the static arrays from __ltostr and __lltostr.
999: optimized away the static arrays (and more!) from strtoul and strtoull.
1000: added system (by Olaf).
1.12 fefe 1001: added tolower and toupper
1.13 fefe 1002: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1003: added clone for mips (by Olaf).
1004: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1005: added pause for all (by Olaf).
1.17 fefe 1006: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1007: added isupper and islower.
1008: added putc and putchar as macros.
1.17 fefe 1009: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1010: insightful discussions and patches I partially used for the last three)
1.18 fefe 1011: added getpriority and setpriority (also by Abraham)
1.19 fefe 1012: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1013: oi, setjmp and longjmp were broken on other platforms, too!
1014: Thanks to Sébastien Côté for reporting this.
1.9 fefe 1015:
1016: 0.7:
1.6 olaf 1017: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1018: Initial dynamic loading glue for i386, also by Olaf.
1019: We don't have a dynamic loader yet, so this is not yet usable.
1020: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1021: vsprintf, writev, all by Olaf.
1.2 fefe 1022: imported readdir fix from Guillaume. Mhh, can the kernel interface
1023: really be this broken?
1.3 fefe 1024: Found a kludgy way to detect whether the kernel includes define struct
1025: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1026: not work for you, please tell me!
1.4 fefe 1027: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1028: Fixed stdio line buffering. The code was already there but I forgot
1029: to mark stdio and stdout as line buffered. This should really be
1030: done dynamically using isatty, though.
1.8 fefe 1031: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1032:
1033: 0.6.14:
1034: *scanf did not append the 0 byte for %s.
1035: added creat and changed creat to call open directly instead of open64.
1036: did for fread what 0.6.10 did for fwrite.
1037: repaired buffered stdio a little (line buffering is still not
1038: supported).
1039: [All of these bugs have been reported by Guillaume. Thanks!]
1040: added __pure__ to strchr and strrchr in <string.h>
1041:
1042: 0.6.13:
1043: included COPYING to make clear that the diet libc is covered by the
1044: GNU General Public License (and _not_ the LGPL). That means that
1045: you need to obtain a license from me if you want to use the diet
1046: libc in a proprietary program that you want to distribute.
1047: The x86 unified syscall swapped arguments #4 and #5 and noone
1048: noticed until now! Thanks to Guillaume Cottenceau for reporting
1049: this!
1050: The malloc had a subtle bug with small allocations that could cause
1051: segfault. Guillaume reported it, Olaf fixed it.
1052:
1053: 0.6.12:
1054: added assert, statfs and fstatfs
1055: added include/net/if.h so fget compiles again.
1056:
1057: 0.6.11:
1058: added putenv.
1059:
1060: 0.6.10:
1061: fixed fwrite. It returned the number of bytes written, not the number
1062: of records. Thanks to Albert D. Cahalan for pointing this out.
1063: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1064: added brk and sbrk. harold@nb.com.sg made me do it.
1065:
1066: 0.6.9:
1067: fixed execvp not to return on ENOENT
1068: did for {open|read|close|seek|tell}dir what I did for stat before.
1069: The glibc compatibility part is currently non-functional.
1070: fixed white space handling in sscanf " (" would not match " (".
1071: fixed printf to accept 'l' flag.
1072: fixed getpwuid (ignored last line)
1073:
1074: 0.6.8:
1075: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1076: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1077: added strlcpy and strlcat from OpenBSD.
1078: added stat64, fstat64 and lstat64.
1079: added endian.h and made ending of strlen.c endianness-aware
1080: added string routines size tweak to dietfeatures.h. Most of the
1081: string routines have been unrolled. This is up to three times as
1082: fast but creates up to three times larger code. Now you can disable
1083: the unrolling.
1084: added sendfile.
1085: I also added pread. It works on x86 and sparc but not on ppc and mips.
1086: I have no idea what's going on. strace disagrees with the kernel.
1087: Can anyone help? I asked the Linux kernel mailing list for help, too.
1088: added a few aliases of the type __libc_open for open. nm on
1089: libpthreads.so indicates that we will need them.
1090:
1091: 0.6.7:
1092: the sources now compile without warnings with -Wall.
1093: printf now prints "(null)" when %s is passed NULL. This can be
1094: removed with WANT_NULL_PRINTF in dietfeatures.h
1095: added vfprintf, execl, ttyname.
1096: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1097: __dietfstat so they can use the normal kernel struct stat.
1098: stat, lstat and fstat are now C wrappers that convert to the glibc
1099: struct stat. So we can avoid that overhead for programs that use
1100: dietlibc headers.
1101:
1102: 0.6.6:
1103: changed the Makefiles so you can now set CFLAGS on the command line
1104: added memccmp (analogous to memccpy) and strncmp.
1105: Olaf fixed another bug in the sparc unified syscall.
1106: Paul Clifford contributed a C version of his strlen.S that is much
1107: more efficient than the previous strlen on all platforms! It also
1108: looks like technology from Roswell. ;-}
1109: added a "real" stdio. Well, almost. Please contribute!
1110: added dietfeatures.h so you can remove features you don't need.
1111: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1112: stdio now works with simple programs and minigzip from libz.
1113: stdio uses some major trickery to avoid linking the stdio, stderr and
1114: stdout (and reserving space for them) when they are not used.
1115:
1116: 0.6.5:
1117: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1118: most of them bugs in the new header files, but also missing sigset
1119: functions.
1120: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1121: several bugs.
1122: Fixed ppc/setjmp and mips/pipe.
1123: Olaf contributed a new sparc unified syscall.
1124:
1125: 0.6.4:
1126: declared is* static inline in getservent.
1127: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1128: changed strlen to return 0 when passed NULL.
1129: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1130: Scientist who actually implemented this without access to a MIPS
1131: box, just from reading the architecture manual. And it worked out
1132: of the box.
1133: started a set of system includes, mainly so that I can use lcc and
1134: my alpha-linux cross compiler (which is unable to cross-compile
1135: glibc). diet libc can now be compiled without any include files
1136: from a normal libc. The includes do declare more than diet libc
1137: currently delivers and they are still far from complete for real
1138: applications.
1139: I will only add assembly versions that are smaller _and_ faster than
1140: the C version. Larger routines are only accepted if they are called
1141: very often and are substantially faster.
1142: added i386 assembly strchr, which is smaller and faster than the old
1143: version. It is, however, larger than the version contributed by
1144: proton (thanks, anyway).
1145: added i386 strlen (31% faster, 14% smaller)
1146: "make t" will now create a map file called "mapfile".
1147:
1148: 0.6.3:
1149: added sys_errlist, strerror and perror
1150: added isblank
1151: added atol
1152:
1153: 0.6.2:
1154: mmap for ARM didn't compile. Thanks, Paul!
1155:
1156: 0.6.1:
1157: split mmap into the architecture specific subdirectories.
1158: getenv now copes with environ==NULL, thanks Paul Clifford.
1159: Paul also contributed a smaller ARM startup code.
1160:
1161: 0.6:
1162: strcat returned the wrong result. Thanks, Dietz Pröpper.
1163: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1164: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1165: __dtostr does not work (I have no idea why!)
1166: The MIPS port now uses (much smaller) non-PIC code. That means that
1167: the applications you link against diet libc also have to be compiled
1168: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1169: Thanks to Ralf Bächle for helping me with this!
1170: I made subdirectories for the architectures and use VPATH to override
1171: VPATH so that make finds the source file automatically. That should
1172: simplify the sources greatly.
1173: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1174: ARM and MIPS now also have setjmp and longjmp
1175: "compile" and "load" are now make targets. Use them for djb programs.
1176: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1177: Again, contributed from Olaf. Great work!
1178:
1179: 0.5.12:
1180: printf also does signed numbers.
1181: If you don't use atexit, dietlibc now does not link exit, only _exit.
1182: *printf now correctly returns the number of bytes written.
1183: Olaf contributed experimental sscanf and vsscanf implementations.
1184: If passed NULL as buffer, snprintf will not write anything but still
1185: return the number of bytes it would have written.
1186: Initial MIPS port! (Oh, the agony!)
1187: No setjmp and longjmp support yet! Please contribute!
1188: I even implemented unified syscalls for MIPS. Still, MIPS code is
1189: almost twice the size of SPARC code. If anyone knows why: please
1190: tell me!
1191:
1192: 0.5.11:
1193: I implemented new unified syscalls for x86, sparc and ppc, this time based
1194: on .s files and not .c files, and I moved the syscalls into
1195: subdirectores to clean the dietlibc sources up a little.
1196: A binary consisting of printf("%s is %d\n","olaf",23) is now
1197: 2864 bytes on sparc
1198: 2488 bytes on intel
1199: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1200: to make a few more applications work.
1201: Olaf Dreesen also implemented some unified syscall stuff for x86.
1202: He discovered that with our unified syscall interface it actually
1203: costs <10 bytes total to make all system calls thread safe!
1204: I implemented atexit() (can register up to 4 callbacks).
1205: I implemented strtod and __dtostr (the opposite). Now we can add
1206: floating point support to vsnprintf and sscanf!
1207:
1208: 0.5.10:
1209: I actually saw that I can not only merge the errno handling code of
1210: the system calls on x86, I can also merge the rest (including the
1211: arguments) except for setting the system call number. All those
1212: system calls are now just a jump to a unified system call handler.
1213: I got rid of x86openclose again. The savings are substantial:
1214: chown from embutils went from 7664 to 7184 bytes!
1215: If I'd move the system call wrappers to assembly language, I could
1216: even reduce the alignment (does not matter since it's just a jump
1217: anyway) and get rid of the "ret" behind each jump (one byte per
1218: system call!)
1219:
1220: 0.5.9:
1221: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1222: fixed strdup
1223: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1224: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1225: (no signed integers, only strings and unsigned integers (but
1226: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1227: that code must be wonderful, I don't understand it at all *bg*)
1228: Olaf's printf does understand padding like in "%08d" and "%8d" and
1229: automatically pads pointers with '0'.
1230: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1231: Thanks to proton for inspiration on this.
1232: The new x86 start code also does not reference exit any more, thus saving
1233: 64 bytes for executables that don't call exit explicitly.
1234: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1235: Moved errno and environ to start.S, saving no byte binary size but
1236: speeding up compilation and slightly shortening dietlibc.a ;-)
1237: For x86: joined open and close into one assembler file, sharing the
1238: errno handling. This is a feasibility test and it actually saves a
1239: few bytes. I think I will reimplement the _syscall[1-6] macros on
1240: all platforms now to share the errno handling code for them.
1241:
1242: 0.5.8:
1243: fixed strchr to be able to look for 0.
1244:
1245: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1246: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1247: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1248: contributed by Olaf Dreesen)
1249:
1250: added execvp, getcwd
1251:
1252: fixed __xmknod
1253:
1254: Note: can it be that the ftw interface really is so broken that I
1255: cannot implement it without having to implement some searching data
1256: structure? I included an experimental ftw implementation that will
1257: not follow symlinks.
1258:
1259: 0.5.7:
1260: oops, if_nametoindex was broken!
1261:
1262: 0.5.6:
1263: ported to ppc-linux.
1264: fixed i386 sigsetjmp (I mistyped the function name)
1265: included sigjmp.c
1266:
1267: 0.5.5:
1268: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1269: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1270: I fixed it now.
1271: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1272: fixed readdir to use getdents and not the intel inline asm
1273:
1274: 0.5.4:
1275: ported to sparclinux (sparc32 only). Beware: does not work yet.
1276: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1277:
1278: 0.5.3:
1279: added tcsetattr and getenv to compile e3
1280:
1281: 0.5.2:
1282: added vhangup, tcgetattr, isatty and memcmp for fgetty
1283: (http://www.fefe.de/fgetty/)
1284: added localtime from uC-libc.
1285:
1286: 0.5.1:
1287: stat and friends actually work now. Yuck! Another case of
1288: translation between kernel and userland. Why can't the kernel
1289: people and the libc people simply agree on a standard?
1290: removed many unnecessary includes to speed up compilation.
1291: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1292: inlined socketcall to reduce code size.
1293: "load" and "compile" are examples for djb code.
1294:
1295: 0.5:
1296: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1297: each object file is now treated with "strip -x -R .note -R .comment"
1298: split each system call into a separate object file
1299: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1300:
1301: 0.4.1:
1302: oops, the strchr implementation was wrong. Thanks Jens Laas!
1303:
1304: 0.4:
1305: copied opendir and friends from uC-libc.
1306: added getservent and getservby* in gerservent.c
1307:
1308: 0.3:
1309: remove readdir system call
1310: added getdents system call
1311: added getpwnam/getpwuid implementation in getpwnam.c
1312: added a few string functions (in str*.c)
1313:
